Business owners often face challenges with financing their companies. Business owners face many challenges when running companies. Competition can be stiff in any industry. Thus, you must find time to keep track of what key competitors are doing. Consumer preferences can also change over time, so you must fully understand what products and features your customers want. You also will face other key challenges with regard to capital, employees and planning. 1. Financing the Business * Owners are faced with the challenge of financing their businesses — both when starting out and during growth phases. Sole proprietors sometimes use savings or investment accounts to start businesses. However, financing your own business can be risky. Make sure you have money for your living expenses when financing your business, as it may take months to earn a profit. It is often difficult to get a bank loan. All banks will check your credit before giving you a loan, so get copies of your credit report and make sure it is accurate; errors can negatively impact your credit score. You also can apply for a loan through the SBA (Small Business Administration). However, the SBA often charges higher interest rates, the Microsoft Business website notes. 2. Building Profits * It can take time to build profits in a business, whether you are using direct sales or advertising to grow your business. You will need reinvest a large portion of your profits into additional advertising. Companies that use advertising build profits by gradually increasing advertising expenditures each month. For example, you may need to spend $500 to make $1,500, a 300 percent return on your advertising investment. Assuming you can average similar returns, you may decide to invest the entire $1,000 profit to make $3,000. Keep in contact with your customers. Try to get repeat sales as often as you can, which also will help you increase profits. 3. Finding Qualified Employees * Small business owners will have the challenge of finding qualified employees. Larger companies usually offer higher salaries and better health benefits than smaller ones, so you may need to find employees who recognize the inherent benefits of working for smaller companies. For example, employees can move up more quickly in a smaller organization. Another option is offering some type of profit sharing. With a solid product concept and business plan, some job applicants will recognize the monetary benefits of profit sharing. 4. Time Management * A smaller but still important challenge for business owners is time management. Small business owners often need to multitask as they have fewer employees to perform routine tasks. The key to mastering time management is prioritizing your tasks each day. Complete the tasks that are most crucial to building profits. For example, go to the meeting with a customer and work on your sales budget afterward.

Negative Mindset The battle always starts in the mind! Our own fears, excuses, and just basically any thing that paralyzes us from moving forward to our destiny is cultivated in our mind. Feelings of inadequacy such as â€Å"I don’t know if I can do this† or â€Å"I am not qualified enough to start this happen† – these are often thoughts that entrepreneurs deal with. This can often come from our own low self-esteem, lack of support, or our upbringing. How to Overcome: a. Do not entertain the thoughts. Remember that whatever you focus on gets magnified. If you pay no attention to it, it will not linger. But for as long as you are nursing it, it will grow in your head and eventually overtake you! b. Surround yourself with positive people. Birds of same feathers flock together is a popular saying but it is true. If you hang with negative people who criticize other people and put them down and do pity party, then before long, you will find yourself like one. See why it’s important to surround yourself with positive people. c. Empower yourself by reading inspirational articles, success stories, great books, movies and anything that will encourage you and motivate you. Attend seminars and workshops if you can! 2. Overwhelming Feelings There is always a huge learning curve when you first start a business. Although you may have lots of experience in the corporate world in your field, it’s totally different when you’re the captain of your own ship. Now, you have to be the boss, the marketer, the secretary, the customer service person, the shipper, and the list goes on! But these overwhelming feelings surely do not only come to starting entrepreneurs. Some experienced and successful entrepreneurs tend to feel overwhelmed at times too so don’t be discouraged. How to Overcome: a. Take short breaks in between your tasks. I find that taking 2 or 3 minute break away from my computer helps. b. Pace yourself. Create a to-do list and make sure that you only put whatever you can handle within a realistic time frame on any given day. c. Outsource some of your tasks. If you’re growing too quick, hire a virtual assistant or a local person who doesn’t mind coming over to your home office to help you out with some tasks. d. Make sure to set aside two days off. A business is a business, however, this time it is yours and you have the flexibility to create your own hours and set your days off without any problem. It is ideal to have a couple of days off or more if you can afford it to avoid possible quick burn out. e. If you’re suffering from information overload, 3. Lack of Support Some entrepreneurs have been blessed to have supportive husbands, family, children, and friends. Some of this support group have the ability to help make the entrepreneur’s business grow but some could only offer moral support†¦which, hey, it’s more than you could ask for! While some of us are blessed like that, others lack both moral and business support. How to Overcome: a. Network with your local business organizations and find people that have the same vision and goal as you do. b. Find a virtual group of people in Social Media that support and promote each other. (Shameless Plugging: Yes, this is what The Entrepreneur Chic Social Club is all about! Details coming soon! *Wink wink*) c. Invest in a mentor or a business coach. 4. Growing a Business The challenge in growing a business mostly lies in the lack of financial resources. Let’s face it, money begets money. If you have the money, it’s easier to put your product out there in hundreds of thousands of people just like the bigger brands, the Fortune 500 companies. You see them on TV, radio, billboards, social media, and sometimes maybe in your inbox! Unfortunately, for most small business and starting entrepreneurs, this is not the case. You have to work hard to make money so you can use that to make more money! How ironic, isn’t it? But that’s where the challenge is! I really do believe that this area of having your own business teaches you a lot about persistence and creates such an experience for you that molds you as a business person. How to Overcome: a. Be patient. Growing a business takes time. The level of effort that you put in is directly equivalent to the level of result you’re going to get but do not expect an overnight result. It’s like planting a seed, it takes time to become a tree. b. Learn as much as you could about marketing (including social marketing) for as long as your brain can handle without overloading it! c. Research on ways you can acquire funding. Be creative! (perhaps you can do your own fundraising technique) See if you might be qualified for a small business loan. 5. Feelings of Wanting to Give Up Because a business takes time to grow and it usually takes a lot of effort to make it work, feelings of wanting to give up do come sometimes, especially when you’re not seeing the results that you want when you want it. Perhaps your funds are already starting to get depleted or you’re getting physically and mentally drained. How to Overcome: a. Do not entertain the thought. b. If you’re not seeing any results, evaluate your product, service, target market, and your marketing strategies. Perhaps your product isn’t the right one for the group of people that you’re presenting it to. Maybe it needs to have a lot of improvement in its presentation/packaging or price. c. Take some time off. Sometimes stepping away gives you a better perspective of where things are at and ideas flow better when your mind is rested. http://www.entrepreneurchic.com/5-most-common-challenges-entrepreneurs-face-and-how-to-overcome-them/ 5 Types of Business Opportunities for Entrepreneurs Are you a restless entrepreneur? Are you the type of person who wants to go into business to be your own boss and succeed through your own decision making? Many people feel the call to become an entrepreneur, but are not sure what type of business to start. There are many entrepreneur opportunities you could choose. Here is a brief look at different types of business opportunities available: Buy a Franchise Many entrepreneurs like to have a business going full speed right off the bat. Rather than spending time reinventing the proverbial wheel, an entrepreneur will buy a franchise opportunity. A franchise is an existing business with a solid business plan and process already in place. An entrepreneur can operate a new business under a recognized business name and receive support from the franchise headquarters with marketing, promotional materials, new business products or services, etc. Good examples of popular franchises are McDonalds and Subway restaurants, home cleaning businesses, Dollar Store, or fitness centers. Distributorship or Dealership Another place to find business opportunity leads is with distributorships and dealerships. A distributor is a person or business that has an agreement to sell products or services produced by another company. Think of an Amway distributor or Avon distributor as a good example. A dealer is much like a distributor, but more focused on one product. An auto dealership may sell only Hondas, or an insurance agent might be considered a ‘dealer’ in life insurance. Network Marketing While an Avon lady might be considered a ‘distributor,’ there is much more to this type of business opportunity. In addition to distributing the products or services offered by the parent company, a network marketer also strives to recruit other distributors. By creating a â€Å"network† of distributors, a person can earn considerable income through residual commissions made from the distributors working under them. This entrepreneur opportunity is also known as Multilevel Marketing. Licensing You might also find entrepreneur opportunities through licensing. Licensing is where you can be creative and invent products, but use the name brand, icon, or trademark of a widely recognized business. Think of Disney products. An inventor may come up with a great idea for a child’s toy that would become a big seller if the famous Mickey Mouse was associated with the product. By obtaining a license from Disney, the inventor could produce his product and profits would be shared by both parties. Filling a Niche While pre-made or other types of business opportunities can be lucrative through a parent or franchise company already enjoying great success, entrepreneur opportunities also exist for a person to simply find a consumer need and discover a way to solve it. Perhaps you are a new mother who finds a need for a baby product not on the market, and therefore, you create and distribute one of your own. Or you are a specialist who finds that other businesses will pay for your consultation and expertise in improving a business function. Any entrepreneur who wants to make a business of his or her own has many types of business opportunities to explore. Find the one right for you and enjoy the success you can build on your own. At the beginning of each year, there is always a little buzz about what will be the next new big ticket. The world is supposed to end in 2012, so I hope you’ll buy 50 pair of underwear, six months’ worth of food rations and about 500 gallons of water. I hope you will make those purchases, not because I think the world is going to end, but because I’m starting an underwear-manufacturing company, a food-rations-supply firm and a water-supply business. Each of these businesses will be hot in the new year as hysteria kicks into overdrive in 2012. Don’t believe me? Flash back to Y2K. Businesses spent around $500 billion to save themselves from impending doom. But nothing happened. Not even a little Y2K postmortem belch. Nothing happened, except that vendors in 1999 pulled in a cool half trillion! So if you’re looking for the next hot opportunity for entrepreneurs in 2012, keep these five areas in mind. 1. Elderly consumers Because people are living longer these days, a flood of products and services will be designed to cater to the older crowd. Businesses will introduce not-so-obvious services. New retirement villages will spring up and new services that cater to the elderly, such as chair lifts for getting into airplane seats. 2. Domestic purchasing With Europe on shaky financial ground, expect businesses to do more domestic purchasing. There is volatility ahead, so if you are based in the U.S. and have competitors overseas, you may have an advantage in 2012. It’s safer to purchase domestically, where buyers perceive more stability, even if it is more costly. 3. Mobile purchasing If you are familiar with Square, you know that this is just the beginning. In 2012, we will see a big surge in payments made with smartphones. Entrepreneurs who have not optimized their websites and their businesses for smartphone transactions are giving money away. In fact, the research firm Emarketer says that smartphone transactions are expected to exceed $6.5 billion by 2015. That’s a lot of coin. 4. Genetic DNA sequencing It’s not the sequencing itself that entrepreneurs need to jump on, but keeping it under $1,000. Technological advancements continue at mind-blowing speed. As Moore’s Law predicts, every 18 months technology doubles in performance and cuts the cost in half. In 2012, we should see genetic decoding available for $1,000 or less. That price point would make it available to the average person. Most people would have the means to determine their genetic propensity to problems, and to take immediate action to live longer and healthier. This will create a boom in DNA-sequencing services and related health care services. Jump on it now, before it becomes another Walmart offering, like flu shots are now. 5. World ending Not. My biggest, boldest prediction is that the world will not end in December 2012 (even though the Mayan calendar shows that it will). But that doesn’t mean there won’t be big opportunities to profit from the hype that will build. It could represent millions, or even billions, in revenue. People spent nearly $1 billion preparing for Y2K to hit, and nothing happened. We are creatures of habit and will likely do the same for 2012. So, if you believe the Mayan calendar may not be accurate about the world ending in 2012, consider ways to profit from these areas. They should be lucrative and provide plenty of opportunity. Besides, the Mayan calendar also predicted that the Kim Kardashian marriage would last more than 12 months, and it was wrong about that, too!

Micro and Nanotechnology Adoption by the Pharmaceutical Industry Essay

Micro and nanotechnology is starting to show promise in the pharmaceutical industry. The two key questions in this field are ‘what is nanotech’ and ‘aren’t all drugs nanotech – after all, they are in the nano size range’. These can be answered fairly simply; Nanotechnology is where the nano-size of a substance affects its activity – the size placing the substance at the interface between quantum and material effects. The classic example to demonstrate these effects is that of gold nanoparticles. Bulk gold is insoluble and metallic-yellow in colour. However, once the gold is formulated as a nanoparticle it is soluble and the size of the particle determines its colour – from bright blue to vivid red. Two key areas where nanotechnology is showing promise in the pharmaceuticals industry are tools for drug discovery, and secondly in formulation and delivery systems. In the development of tools to support drug discovery, nanotechnology is developing a trend to move away from high throughput to high content screening, where greater information on fewer compounds is achieved. As our knowledge about drug-target interactions increases, it is becoming apparent that high-volume/low-content screening can miss extremely interesting interactions and effects. For example, SPR biosensors can detect a ligand binding step and measure the binding constants. But it cannot measure surface stresses caused by binding, which are an important factor for example in antibiotic efficacy against MRSA and VRE. Here nanomechanical cantilevers have been shown to be effective in providing extremely elegant information that can explain the difference between various drugs that appear to have the same binding kinetics.[i] The move to high content screening has been slow due to the large investments in high throughput screening laboratories and so new systems need to be compatible. However, where systems are compatible with these techniques – for example using 96 well plate platforms, adoption is possible. As a result, improvements and adoption is currently iterative, rather than revolutionary, but it is happening. With regards to nanotechnology in formulation and delivery science, there are a number of early adopters of nanotechnology in the pharmaceutical industry. Table 1 shows a number of types of nanoparticle formulations that are already approved for marketing. The full list of approved ‘nano-enabled’ products is very small and those that have made it to the market are generally reformulations of existing generic drugs. We are still awaiting the second-generation nanodrug, where the nano-effect is integral to the product activity. Nanotechnology appears to be following the classic technology adoption curve as shown in Figure 1. This shows the bell-shaped adoption curve for any technology, overlaid by the technology acceptance line. Nanotechnology appears to have passed through the hype and trough and is now starting to be slowly adopted. It appears that the problem for nanotechnology in formulation is one of risk. Companies need to get their products to market quickly to allow as much market exclusivity time as possible – not to recoup their investment, as this is a sunk cost, but to recoup the cost of developing future drugs, the cost of which is becoming ever more expensive. The Tufts Center for Drug Development estimated that the cost of bringing a single drug to market was in the order of $1.2 billion in 2008, compared to $802 million in 2000.[ii],[iii] Given these issues, companies won’t adopt new technology unless they know that the technology has a clear and fast route to approval. This is particularly poignant in drug formulation and other rate-limiting activities that occur post-patent filing. Once a patent is filed, the clock is ticking on the product’s life. If a product is going to be a $1billion a year blockbuster, lost revenues will be at least $2.7 million for every day a product is held from the market. This produces a catch 22 scenario; no-one will take the risk to demonstrate a new technology, especially if it is competing with existing and proven methods, so no-one will see a clear adoption path and use it. This is reminiscent of the fledgling biotech industry 15-20 years ago. Pharma was focussed on small molecules and didn’t want to risk bringing into their portfolio relatively unstable products, with complex manufacturing methods and which were without a clear regulatory pathway. Now however, many traditional large-pharma refer to themselves as biopharma companies and Amgen and Genentech (prior to the Roche purchase) are in the top twenty pharma by revenue. Early adopters, such as Abraxis and Elan, have started to clear a pathway to approval, but as yet no company has developed a true nanodrug – ie one which was conceived as a nano-enabled product from first principles as opposed to using nano-formulation on existing products. Nanotech has a lot to offer the pharmaceuticals industry and if it follows previous technology examples such as biotech, the successful early adopters will reap the rewards. It still has a number of hurdles to leap, such as a clear regulatory pathway and a demonstration of value above and beyond current technologies, before it can become mainstream. However, there are significant efforts by industry and governments to help it to jump the technology adoption gap quickly and ensure it can assist in developing the next generation of products that are needed to solve some of the significant unmet medical needs faced by patients and healthcare professionals. ———————– [i] Ndieyira, J.

Computer Operating System

An operating system (OS) is like a facilitator, providing an environment for application programs to run in. It provides an interface between computer hardware and the user of the application programs. Application programs are a stored set of instructions for responding to a specific request. Hardware are the physical devices that make up the system such as the monitor, keyboard, printer, ect. The OS typically includes anywhere from tens to thousands of built-in subroutines called functions which applications can call to perform basic tasks such as displaying a string of text on the screen or inputting a character from the keyboard. The OS allows the user to interact with and obtain information from the hardware through a series of layers. The command layer is the only part of the OS that interacts with the user and sometimes is referred to as the shell. It is the user†s interface to the OS in that the user can request system services via a Job Control Language (JCL), which is the set of commands and their syntax requirements, or through a GUI (Graphical User Interface), the newest command language. The command interpreter decides which services must be executed to process the request and passes these to the service layer. The service layer accepts the commands and translates them into detailed instructions. There is one service call for each number of system requests provided by this layer. It handles functions in process control, file control, and device control. It makes requests to drivers for access to the kernel layer, which interacts directly with the hardware. Input must travel through these layers to reach the hardware and the results must travel back. First and foremost, an operating system must provide a mechanism for starting processes, which most of us know as programs. There are two main types of operating systems: single-tasking and multitasking. DOS is an example of a single-tasking operating system, which simply means that it can only run one program at a time. Windows95 (or newer editions, prior editions were a GUI interface to DOS) is the most widely used multitasking operating system on PC†s. Multitasking means that many programs can run at the same time. The processor (CPU), which selects and executes instructions, must divide its time to each active application to make it appear that all are running at once. These types of operating systems contain schedulers that divide the processor†s time among active processes. The schedulers are located in the kernel. Each process has one or several threads of execution. Every few milliseconds the scheduler takes control of the CPU from the thread it is currently executing, uses a complex time-allocation algorithm to decide which thread should execute next, and continues executing the thread at the point where it was last interrupted. The next fundamental duty of an operating system is to manage the memory – or storage of data – available to it and its applications. The goal in memory management is to give each application the memory it needs without infringing upon memory used by other applications. When a program is loaded and ran, the OS allocates a block of memory to hold the program†s code and data. If a program requires additional memory, it can call a function in the operating system to request more. DOS does not handle memory very well because it runs in real mode, where only 1MB of RAM (Random Access Memory) is addressable. The RAM is volatile memory that stores the running applications but the information is lost when the computer is turned off. Windows95 does a much better job of managing memory because it runs in protected mode, which allows it to use all memory, including extended memory. And even when that much memory isn†t enough, it can make more available by creating virtual memory from free space (space that has nothing stored in it) on a hard disk (non-removable secondary storage hardware device). Virtual Memory is a memory management technique that only loads active portions of a program into main memory. Windows95 also takes steps to prevent an application from accessing memory that it does not own. In DOS, and application can write to someone else†s memory, including the operating system†s, which can crash the entire system. Windows95 runs applications in private address spaces that are logically isolated from each other and identify the start of the file. One of an operating system†s most important components is its file system – the part responsible for managing files stored on hard disks and other mass-storage devices. An operating system provides high-level functions that applications can call to control file I/O, which covers the opening, closing, creating, deleting, and renaming of files. To read a chunk of data from a file, the application calls an operating system function and passes the operating system the file handle (which uniquely identifies an open file), the address in memory where the data should be copied, and the number of bytes to copy. The OS has to identify each sector on the disk that holds a portion of the requested file and program the drive controller to retrieve the information, sector by sector. It has to do this efficiently so that the information is retrieved quickly. The OS finds the right locations on the disk because it keeps a map that contains the name of each file and a record of where it is stored. DOS and Windows95 use a file allocation table as a map to find the locations. Another role that operating systems play in making a computer work is controlling device I/O. A device is a piece of hardware such as a video adapter, keyboard, or mouse. To talk to a device, a program must speak the device†s language, which usually consists of streams of 1†³s and 0†³s. There are thousands of different devices and â€Å"languages†, so the OS helps out by serving as an interpreter. It talks to the devices through device drivers, which are interface programs specially designed for each individual I/O device. Most operating systems like Windows95 come with dozens of different drivers for each I/O device. DOS also uses drivers, but they are often so primitive that the applications perform device I/O by relying on low-level routines encoded in ROM (Read Only Memory – allows the data to be read but not written) in the computer†s BIOS (Basic Input/Output System) or by talking directly to the hardware.

Change in Boiling Point of Water with Molarity Essay

Change in Boiling Point of Water with Molarity - Essay Example In the beaker A NaCl was not dissolved. Concentration of this solution was expressed as 0 molar aqueous solution (0M). In beaker B 5.8gms of NaCl was dissolved and hence a 1 molar aqueous solution (1M) was obtained. In the beaker C 17.4gms of NaCl was dissolved and hence a 3 molar aqueous solution (3M) was obtained. Lastly in the beaker D 29.0gms of NaCl was dissolved and the molarity of this aqueous solution was 5M. It is very clear that boiling point of the solution increases with molarity of the aqueous solution. It implies that the boiling point of water and the amount of dissolved salt, or molarity of the solution, are in direct proportion. If the increase in temperature were to be denoted by t and the molarity of the aqueous solution by M and if k were to be a constant, then, 4) The exact amounts of salt to get 0M, 1M, 3M, 5M aqueous solutions respectively should be dissolved in the water in the beakers. The formula Molarity = Moles of solute/Liters of Solution should be used for this purpose1. Some of controlled variables are Normal Pressure of 1 atmosphere, Identical beakers in all regards like made of same dimensions and material, The burner level, Pure distilled water, etc. The independent variable was the molarity and the dependent variable was the temperature.

Research Proposal on the effect of hydrostatic pressure on plants

On the effect of hydrostatic pressure on plants - Research Proposal Example The four plants will be subjected to external pressure values in a closed medium for a period of two months, while the one (controlled plant) will be left in the opening, without the closed medium pressure control. Water level and pressure will be monitored every 2-3 days to insure their constancy using two method while the water flow measurements are taken. The plant will experience four different external pressure values in a closed medium for approximately two months. Water level and pressure will be monitored every 2-3 days to insure their constancy using two methods. Factors such as stem length and diameter leaves length and manifestation, room and soil temperature, water soil to leave ratio, coloration, and other vegetation and evolving aspects will be measured. The observed changes in the above factors would be compared to observed changes in these factors in the case of the control plants, in an attempt to identify the effect of an external pressure on a plant. Aim of the Stu dy Osmotic pressure is that pressure that is required to be applied to a solution in order to prevent the flow of water inwardly across a semipermeable membrane (Edward 34). Fundamentally, it is the minimum pressure required to nullify osmosis. ... Studies have shown that many plants require osmotic pressure for purposes of performing many functions. For instance, herbaceous plants depend on turgor pressure on the plant cell wall to allow them stand upright. Moreover, the regulating of the opening and closing of the stomata in plants is only achieved through osmotic pressure. Animals cells, on the other hand, lack cell wall, thus excessive osmotic pressure can cause cytolysis. The importance of osmotic pressure has been the reason behind increased studies on this subject. Osterhout1 (34), for instance sought to investigate the process of water movement in a cell in a process referred to as osmosis. In other studies, Mees and Weatherley (56) carried out an experiment to ascertain the mechanism of water movement in plant roots. Similarly, Voet, Judith, Voet and Pratt, (56) sought to investigated the application of osmosis in Biochemistry. Fiscus (1975) explored the interaction between Osmotic and Pressure-induced Water Flow in Pl ant Roots. In this research Fiscus was confined to the interaction of water and solute transport in the detached root systems and the non-linear relationship existing between driving force and water. In yet another study, Edward (35) demonstrated that under influence of applied hydrostatic pressure gradients there was a drop in resistance of water flow in the detopped tomato root systems. In this study, Mees and Weatherley showed that in simple membrane systems, it is possible to have changes in water conductivity with increasing hydrostatic pressure without actual change in the hydraulic conductivity coefficient. The findings of this study, as well showed that in absence of hydraulic pressure gradient, such a system may develop a steady state concentration

It has furthermore provided a way to personalize brands and help spread out the brand message in a conversational and relaxed mode. BMW (Bavarian Motor Works) a Germany manufacturing company that specializes in automobiles, motorcycles, as well as engine making was founded 96 years ago and has operations worldwide with divisions and manufacturing plants in more than 13 countries on all five continents (Robson, 2008). BMW and Honda are two different companies targeting very different clientele. BMW generally invests a lot in technology 85% of their investments is in technology as their target market are the affluent buyers which in turn helps BMW maintain its incredible high margins. Honda, on the other hand, is more focused on price tags and mass production of vehicles to maintain or even make profits. Furthermore, it can be said that customers of Honda can upgrade to BMW status while BMW customers very rarely downgrade to Hondas. Since BMW invests heavily in technology, with the use of their e-marketing strategy, which incorporates social network applications with the likes of Facebook, YouTube and Twitter in order to reach a high number of people at fairly low costs. BMW’s use of social media allows for multimedia as well as interactive communication with numerous customers thus allowing better marketing (Mbwette, 2013). While Honda, on the other hand, has less than 50% investment in technology but rely mostly on pricing and TV commercials to make sales in the various countries that Honda sells because the Honda company is generally reluctant on spending money especially to do with promotions. Regarding BMW, the general overall impressions are impressive their business model is great, everything

Historical Events - Research Paper Example The development and expansion story of education has just remained to be one of the expanding accesses with various differences arising at every dawn of collegiate growth in each new era. Higher educational institutions were largely supported by the educational philanthropists whenever reflected back in the 12th century during the time of medieval universities development (Riesman, 2001). The higher education system is perceived to have mainly originated in the United States whereby its development has been influenced by a series of events. The federal government became directly linked to the higher education during the time of the civil war. During this period, the southern congressmen who had a tendency of opposing the legislature were missing in the action. Most of the proposals and objectives were created under the Morril Act of 1862 that was in pursuit of the educational motion gearing programs. Among the programs proved to subdue the higher educational programs included: mechanical, agricultural, and military sciences encompassing the liberal arts. The state decided to attach some new programs like agricultural and engineering to historic colleges. This was aimed at boosting the political strength and expansion of the university definition scope and the curricula between 1887 and 1914. This Act of Morril was termed as the land grant-act due to the collective su pport gain exert on colleges to enhance development. The second Morril Act of 1890 considered to be the latest stimulated the expansion power of the federal engagement in the education development. This led to the funding of projects that related to land-grant campuses (Razzell, 2006). Basing on the Morril Act with the federal legislation furry, African –Americans were faced with great attention through the receivership of mixed results due to differences experienced in treatment. This act provided the policy of strictly funding the African-American

However, the construction process was delayed by 1 week. The planning process also realized delays of about 3 weeks. In total, delays in the schedule were 4 weeks (approximately 1 month). The planning permission was to commence on March 1, 2013 while construction was to begin a month later (April 1). It means that the first complete housing units were to be rescheduled to the end of October. The sales process should have started on November 1, 2013. The sales would remain at the same rate indicated earlier in the feasibility study since the shifts in house sales have not affected the current revised rate. It remains at 2 housing units sold per month. However, completing the sales would be realized three in February 2014. There are changes on the interest rate charged by the financial institution responsible for the funding of the housing project. With the increase in the rates of interest, loan facility would have to be viable until the end of February 2014. The simple interest would have to be scaled to 1.3% or simply 1% because of the 0.8% rise in the simple interest rates. The interest on the loan facility remains at the original schedule of a quarterly model in arrears. The developer’s cash will be used to pay it out. Roll-ups will not be allowed on the payments. The commitment fee of  £5000 will not be affected by scaling up the interest or the changes in planning and construction schedules. It will still be paid once the loan has been processed. The disposal fee of  £500 per housing sold will also remain unchanged. The funding of construction costs in a revolving basis will not be affected by the changes. It will remain at  £525,000.

Landscapes and Film Essay Example | Topics and Well Written Essays - 1000 words

Landscapes and Film - Essay Example esis statement: In the film Witchfinder General, the director (say, Michael Reeves) makes use of the landscape as an effective and active container or important character to prove how beautiful landscapes can be used to portray human attitude towards violence, bloodshed, and manipulation within horror film genre. The opening scene (see, appendix-1) in the film Witchfinder General is symbolic of the director’s decision to make use of British landscape as a contrasting character against violence and bloodshed. For instance, the director blends the beautiful British landscape with the hanging of a lady by a group of witch hunters. The scenic beauty of British landscape, including villages, hills, and trees are beautifully portrayed in the film. The viewer may suspect that the director is trying to divert his/her attention from the violence and bloodshed in the film. In actual sense, the director is aware of the fact that landscape is important to a film with historical and cultural importance. If the film’s background is different, the viewers may not feel the presence of British culture. The director chose an important time period within British history (Civil War era), for his film. To be specific, the British civil society underwent rapid transformation during the Civil War. During this period, armed conflicts and unexpected rebellions were usual in the society. The fight between the rebels and the supporters of the monarchy created trouble among the mass. Besides, the civil war ended by making sure that the parliament (symbolic of the people) will be an influential factor within British politics. One can see that rural England is renowned for its scenic beauty. Within this context, Matthew Hopkins’ (say, the antagonist) unexpected arrival at the village is symbolic of the urban invasion on rural atmosphere. To be specific, the director makes use of the antagonist to prove that his arrival created trouble among the villagers and destroyed their peaceful

Oral Script About Titanic Essay Example for Free

Oral Script About Titanic Essay Good morning to my teacher and fellow friends. Today I want to talk about the sinking of Titanic. RMS Titanic was a passenger liner that sank in the North Atlantic Ocean on 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton to New York City. The sinking of Titanic caused the deaths of 1,514 people in history. She was the largest ship afloat at the time of her maiden voyage. One of three liners operated by the White Star Line, she was built between 1909-11 by the Harland and Wolff Shipyard in Belfast. Her passengers included some of the wealthiest people in the world, as well as over a thousand emigrants from Britain,  Ireland,  Scandinavia  and elsewhere seeking a new life in North America. The ship was designed to be the last word in comfort and luxury, with an on-board gymnasium, swimming pool, libraries, high-class restaurants and opulent cabins. She also had a powerful wireless telegraph provided for the convenience of passengers as well as for operational use. Though she had advanced safety features such as watertight compartments and remotely activated watertight doors, she lacked enough lifeboats to accommodate all of those aboard. Due to outdated maritime safety regulations, she carried only enough lifeboats for 1,178  people – a third of her total passenger and crew capacity. After leaving Southampton, England on 10  April 1912,  Titanic  called at  France  and Ireland before heading westwards towards New York. On 14 April 1912, four days into the crossing and about 375 miles south of Newfoundland, she hit an iceberg at 11:40  pm. The glancing collision caused  Titanics hull plates to buckle inwards in a number of locations on her  starboard  side and opened five of her sixteen watertight compartments to the sea. Over the next two and a half hours, the ship gradually filled with water and sank. Passengers and some crew members were evacuated in lifeboats, many of which were launched only partly filled. Just before 2:20  am  Titanic  broke up and sank bow-first with over a thousand people still on board. Those in the water died within minutes from  hypothermia  caused by immersion in the freezing ocean. The 710 survivors were taken aboard from the lifeboats by the  RMS Carpathia  a few hours later. The disaster was greeted with worldwide shock and outrage at the huge loss of life and the regulatory and operational failures that had led to it. Many of the survivors lost all of their money and possessions and were left destitute; many families, particularly those of crew members from Southampton, lost their primary bread-winners. They were helped by an outpouring of public sympathy and charitable donations. Some of the male survivors, notably the White Star Lines chairman,  J.Bruce Ismay, were accused of cowardice for leaving the ship while people were still on board, and they faced social ostracism. The  wreck of the  Titanic  remains on the seabed, gradually disintegrating at a depth of 12,415 feet (3,784  m). Since its rediscovery in 1985, thousands of artifacts have been recovered from the sea bed and put on display at museums around the world. Titanic  has become one of the most famous ships in history, her memory kept alive by numerous  books, films, exhibits and memorials. That’s all. Thank you.

Ethics & Philosophy Essay Example for Free

Ethics Philosophy Essay Free markets can be said to be the markets which have no government interference or regulation. The only regulations present are the ones which involve protecting property rights and maintaining the legal system. Free markets are markets in which the product prices are solely set through market forces, as opposed to interference by external forces. There is also free competition in free markets, and the law of supply and demand is used to fix prices of goods and services in such markets. There are various philosophers who support free markets while others are opposed to such markets. The paper will analyze the contributions of Adam smith, Karl Marx and Milton Friedman on the issue and will give a brief conclusion on the issues discussed. Karl Marx. Karl Marx was a German philosophers who is considered to be amongst the most controversial philosophers in history. He was against capitalism and free markets, which he viewed to be a means with which property owners or the rich use to maintain control over the peasants or poor. Karl Marx viewed the capitalist system as a system meant to make the rich richer and the poor poorer. He explained that initially, capitalism was meant to be a means with which people exchanged commodities which they did not have. However, after money was created, it evolved and became a means with which people could make profits as opposed to satisfying the demand for products. Over time, capitalism undermined the human development and well being, and products created could now dictate how interactions between human beings would be. Soon, the relations between society became material as everything was treated in terms of its monetary worth, as opposed to creative and artistic qualities possessed. Capitalism led to the alienation of workers since they were separated from owning the means which was used for production, and they became slaves to the people who owned those means. This led to the emergence of two economic groups; the property owners and the workers, and the latter were oppressed by the former. This is the reason which made him predict the collapse of capitalism and its replacement with socialism. Socialism is a system in which the government or authority controls production so that it may be mutually beneficial to all members of the society or state. Karl Marx was opposed to free markets since they tended to favor the rich and oppress the poor. Free markets are a feature of the capitalist system, which made Karl Marx oppose them. Weaknesses of this argument. Karl Marx is opposed to free markets due to the weaknesses which he views in capitalism. Karl Marx views capitalism to be a system where the rich oppress the poor. He therefore opposes all features of capitalist systems which he views to be a means which promote the exploitation of the poor . However, Karl Marx does not consider the model which combines both capitalism and socialism in order to take advantage of the positive attributes of the two models. Since socialism has its weaknesses, combining both models may be more beneficial to the economy. In this respect, moderate government interference in trade by the government is an option which Karl Marx should have pursued. Adam Smith. He is considered to be the father of the modern economics and he contributed a lot toward the modern capitalist system. Adam Smith was of the opinion that production was the key to economic growth and that this could only be achieved through economic liberalization. Adam Smith therefore supported unregulated markets since he saw them as a means of stimulating economic growth. He explained that free markets would enable individuals to develop a business without having government intervention, and that the people who consume the products developed would do so at prices which have been determined by demand and supply forces . Adam Smith added that free markets enabled the most competitive producers and consumers to survive, which was beneficial to the economy. He viewed free markets are independent problem solvers which did not require government interference, since market forces eventually address any surpluses or shortages which are inherent in the market. Adam Smith uses the invisible hand theory to explain the way in which different parts of the economy are integrated. Smith explains that each individual is guided by an invisible hand in making their decisions which benefit the economy, without their knowledge. He explains that individuals carry out actions which are meant to benefit themselves, but they end up benefiting the society at large, which is not the initial aim of the individual. Smith gives an illustration of the creation of a wool coat. He says that the coat is developed after a series of processes which are undertaken by different people. The shepherd who owns the sheep, the spinner who develops the coats, and the shipper who transports them to the market all play a role in the creation of the finished product. He explains that this subconscious process by the different parties involved achieves higher levels of efficiencies than would be achieved had the process been planned by the players involved. It means that markets which are regulated by the government have lower efficiency levels compared to markets which are not regulated . This is the major reason why Adam Smith supports the free markets as opposed to regulated markets. Weaknesses of this argument. Adam smith is of the opinion that free markets enabled the most competitive producers and consumers to survive, which is beneficial to the economy. He gives many attributes of free markets, most of which are true. However, he does not discuss the weaknesses of free markets. Free markets suffer from certain weaknesses such as inhibiting the growth of small firms. Free markets may also experience monopolistic and oligopolistic tendencies which adversely affect the economy. The economy may also suffer certain effects attributed to unfair practices in trade. Other effects like inflation, market downturns and others require regulation by a central authority. Adam Smith does not discuss these situations, which makes his argument inconclusive. Milton Friedman. Friedman made major contributions to the economic crisis during the early 20th century. He viewed the 1920s as a period of sustainable and vital growth. Friedman believed that economic growth and freedom had a direct relationship. He used several principles and arguments to further his support from free markets. The political principle was used by Friedman to define the features of free markets. He explained that in free markets, individuals cannot coerce each other and that there is voluntary cooperation between the parties involved . He further explained that parties which are involved in transactions under such circumstances benefit in one way or another, otherwise they would not participate in these transactions. In free market transactions, there are no social responsibilities and values; there are only shared responsibilities and values. However, Friedman was also of the opinion that the government should intervene in the economy if there is threat to it. One of the instances when Friedman supported government interference was during the Great depression which occurred in 1929. The Great Depression changed the view that the United States economy was robust and that it should be totally free from government control, after the US Stock Exchange collapsed due to various factors. Friedman supports the market regulation and explains that if the Federal Government had intervened and applied the right policies, this depression would have been avoided. He explains that the Federal Government should have suspended payment for the withdrawals being requested by people. The policy which was used at the time, which involved printing more money to supplement the increased demand, is blamed for the Great Depression. This reveals a more soft approach to the initial stand that government intervention should not be allowed, and that the markets should be allowed to operate as free markets. However, it does not completely change the stance which had been taken by Friedman regarding free markets. Government interference is allowed only under special circumstances where lack of intervention would lead to severe effects to the economy. This was the case during the Great depression and is also currently the case in the event of the global financial crisis being experienced. Weaknesses of this argument. Friedman is categorical that there should be free markets if economies are to grow. He argues that the absence of social values and responsibilities and the presence of shared values are factors which facilitate economic growth. However, he appears to take a soft stand when discussing the Great Depression where he advocates for government interference, but using the right policies. This is a deviation from his stand that the government should not interfere with the business environment. It also reveals that free trade has weaknesses which he does not effectively address. Personal view. In my opinion, free markets do not lead to serious political, social, or environmental problems as explained by some philosophers. This is because free markets are the most effective and natural means in which prices should be set to ensure effectiveness. On the contrary, a wrong approach of interference by the government may lead to serious political, social, or environmental problems as was seen in the Great Depression. The current financial crisis which began in the United States can also be said to have been accelerated by the government failure to limit the borrowings by investors and excess lending by financial institutions using predatory lending practices. This is a similar problem which led to the great depressions, and the government interference is seen to have led to adverse effects rather than positive effects on the economy. However, in extreme cases of economic problems, the government should intervene. This should only be done to save the economy in cases where the market forces are clearly unable to rectify the situation. For instance, the current financial crisis facing the world requires the governments intervention. This does not mean that the government supports the regulation of markets since in the absence of economic crises, the market forces would usually be used to set the product prices. My major reasons for supporting free markets is that regulated markets usually discourage investments, especially if the regulations are too strict. Investors prefer investing in countries where there is free trade since they can predict their future earnings or returns on investment, due to the absence of external factors in the business environment. Regulated markets may also adversely affect the economy especially if the policies which are applied are retrogressive. Summary and conclusion. It is evident that the three philosophers made major contributions to the modern world. Their theories are still in use several years after some of them passed away. However, it is important to note that their arguments relating to free trade are inconclusive since some of the facts which they used to support their arguments have changed. It is also important to note that none of them has a wrong view, it is only that they looked at free trade from different perspectives. The contributions which each of them has made to society should be appreciated since they all talked about various issues affecting the society, and not just free trade. It is important that other scholars improve on the theories which were advanced by Adam smith, Karl Marx and Milton Friedman. This will reflect the market environment as it is today, and the arguments developed can be used to improve the policies in the current business environment. Works cited. Amadae Samuel.

Discharge of Water through a Spherical Orifice

Discharge of Water through a Spherical Orifice There are multiple factors that affect the discharge of water through a spherical orifice. These can include the height of water above the incision, the cross sectional area of the hole and the shape of the hole that the fluid is flowing through [New Century Senior Physics 2004]. But first of all, what is fluid?       Fluids are defined as any substance that cannot sustain any tangential or shearing force while maintaining its form at rest, basically any substance in the form of a gas or liquid [Britannica 2017]. They generally have no fixed shape and when exposed to stress, the fluid will experience a continuous change [Britannica 2017]. Flow is a universal property for all fluids [Britannica 2017]. For liquids in particular, the flow is influenced by the acceleration due to gravity. If the fluid is non-viscous and incompressible, while the flow of the fluid is steady, then this flow can be seen from an energy perspective [Fluid Mechanics and Bernoullis Principle 1999]. In pipes, there are two factors to allow a fluid to flow, the first method is to tilt the pipe so the fluid gains Gravitational Potential Energy [Fluid Mechanics and Bernoullis equation 1999]. This is defined as the stored energy that liquids or solids with mass possess that is dependent on the acceleration due to gravity and the respective height the object or substance above the ground [Hyperphysics 2017]. When the pipe has been tilted enough, the flow will be downhill, this moment is where the accumulated gravitational potential energy is transferred to kinetic energy, the energy of motion, hence creating the flow of a fluid [Fluid Mechanics and Be rnoullis Principle 1999]. The law of conservation of energy states that for any physical or chemical change, energy cannot be created nor destroyed, this describes this procedure of the energy transfer previously mentioned [Madden et al. 2004]. {FLOW} The second method to make a fluid flow is to increase the pressure at one end of the pipe so it is larger than the pressure accumulated on the other end. This in turn creates a pressure difference which acts as a net force, accelerating the fluid through the pipe which is known as flow [Fluid Dynamics and Bernoullis Principle 1999]. Jets are a common form of fluid flow. They are defined as a fluid discharged forcefully through a narrow opening or orifice, resulting in a stream like motion [Meriam Webster 2017]. One of the main components of the jet is its velocity, this is affected by multiple factors including the holes size and shape, the fluids pressure and viscosity, even the medium which it passes through can, inhibit the jets potential velocity. If the composition of the jets fluid is somewhat identical with a stationary medium surrounding the flow, the jet can be classed a submerged jet [Farlex Inc 2017]. Examples of this flow are the air currents through a still atmosphere, this is because the fluid is air and the surrounding media is also air [Farlex Inc 2017]. There are many other forms of jets including free jets which are the opposite from submerged, they are where the jet passes through unbounded mediums. Semi-contained jets occur when the jet passes along a flat surface while confined jets exist in mediums bounded by solid surfaces, for example a pipe with a diameter larger than that of the inlet [Farlex Inc. 2017]. {Jets, discharge, vena contracta?} When fluid jets are in motion, their cross sectional area is quite often subject to contracting. The site of this contraction is known as the natural phenomenon of vena contracta, which can be defined as any of the locations in a jet of fluid emerging from and orifice where the flows cross sectional area is at its minimum [Dicionary.com, LLC 2016]. Vena contracta usually occurs as a result of the fluids streamlines converging as they approach an orifice [Calvert J.B. 2003]. Generally, this leads to the cross sectional area of the jet decreasing slightly until the pressure in the cross-section has been equalized, it is also at this point where the jet experiences its maximum velocity in its flow [Calvert J.B. 2003]. Beyond the site of vena contracta, the jets streams start to diverge as a result of friction and drag caused by the jet flowing through another fluid, in this case, the air surrounding the flow [Calvert J.B. 2003]. The cross-sectional area will increase while the jet decel erates from the surrounding fluid as a result which is why the jet can be seen transforming from a constant flow to small droplets. Jets are held together by surface tension which is why they generally do not continue to be a perfect flow, this tension has a stronger effect the smaller the diameter of the jet [J.B. Calvert 2003]. This is why decreasing the size of the orifice will lead to an increase in the displacement of the jet from the container because by decreasing the cross section, the jet will accumulate more velocity at vena contracta. Pressure is another factor that affects the displacement of the jet from the orifice. If the pressure accumulated inside the container is substantially high, the fluid tends to compress in a closed container [Spence Regan 2007]. However, if the fluid is incompressible like water, an increase in pressure will generally lead the fluid molecules to basically push up against the walls of the container as it attempts to decompress back to the normal atmospheric pressure surrounding the container [Spence Regan 2007]. Because of this, when a leak has been sprung in a container consisting of a pressurized fluid, the fluid will be inclined to escape, and with more pressure, the faster the fluids discharging velocity will be [Khan Academy 2017]. Naturally, especially when dealing with water as a fluid, pressure is most commonly affected by and directly proportional to the height of the waters (fluids) surface above the specific measured location, or the depth of the location from that surface [Madden et al. 2004]. The reason for this is because the height of the fluid administers a mass over that specific location, which then, assuming that the fluid analysed is influenced by the acceleration due to gravity, a force will be produced as stated in the equation below [Madden et al. 2004]. or [Madden et al. 2004] This accumulated force will result in Pressure through the equation Where: P= Pressure (Pa) f=force (N) A=Area (m2) [Madden et al. 2004] However in fluid mechanics, another more accurate equation is required, this is known as Bernoullis equation which relates to Bernoullis Principle. This principle is based on the law of conservation of energy and states that a fluids pressure decreases when it is subjected to increased velocities, vice versa [Madden et al. 2004]. The pressure, velocity or heights of surfaces above the hole in most fluids are related to the same parameters at a second point through Bernoullis equation as stated below [Fluid Dynamics and Bernoullis equation 1999]. Where: P=Pressure (Pa) à Ã‚ =Density (kgm-3) v=Velocity of Fluid (ms-1) g=Acceleration due to gravity (ms-2) h=Height (m) [Madden et al. 2004] The pressure of a fluid at depth can be given through a derivative of Bernoullis equation. Where: Ph=the pressure at depth (Pa) à Ã‚ =density of fluid (kgm-3) g=acceleration due to gravity (9.81ms-2) h=the height of the fluids surface, in this case the water, above the specific location where Pressure at depth is measured. Ptop = the pressure at the fluids surface (Pa) [Madden et al. 2004]. This equation can be used to find the pressure at certain points like at the same level as the orifice inside the bottle [Madden et al. 2004]. For this experiment however, the pressure will be measured and calculated at the same level as the orifice and since the pressure at the fluids surface can also be considered as the air temperature inside the room this will also be used in the equation. For eg, If the waters density, the acceleration due to gravity and the air pressure were kept at constant while the height of the surface above a certain location was increased, then the Pressure at that location should also increase like so [Madden et al. 2004]. If à Ã‚ =1000kgm-3, Ptop=94500Pa and g=9.81ms-2 When h= 10m [Madden et al. 2004] This is important in many applications like dams, towns and especially high rise buildings. Water will need to be mechanically pushed up to the top of a building so people at the top floors can have sufficient water to have a shower [Madden et al. 2004]. It is also because of this understanding of fluid mechanics that hilly cities often build water towers or reservoirs at the top of hills or mountains to help accumulate this needed pressure to effectively distribute water to the population [Madden et al. 2004]. Pressure can directly affect the exit velocity of the fluid being discharged as it flows out through an opening in any form of container or reservoir. This is known as the velocity of efflux and is determined through many similar formulae. The most common is derived from Torricellis theorem which is about the relationship between the height of the fluid above the orifice, and the exit velocity of the fluid projected from a sharp edged orifice [Boundless 2016]. The law also states that the speed (velocity) of a liquid flowing under the influence of gravity out of an orifice in a reservoir is directly proportional to the square root of the vertical distance between the surface of the liquid and orifice and the square root twice the acceleration due to gravity [Britannica 2017]. The equation that relates to this theorem is stated below. Where: Vi= Velocity of Efflux (ms-1) g= Acceleration due to gravity h= Height of the fluids surface above the orifice This velocity is a result from a transfer of potential energy to kinetic energy [Boundless 2016]{Torricellis Law and height/Displacement} Other deviations of this equation can be used to factor in for orifice and container sizes like displayed below. Where: A= Area of Container (m2) a= Area of Orifice (m2) [CalcTown 2017] In this case the areas can be calculated using the standard area formula for a circle. According to calculations using this formula however, velocities are not effected significantly from changing the containers area or even the orifices area. But the area of the orifice seems to affect this velocity more adversely than the area of the bottle which is why changing the area of the bottle will not be tested in the experiment [CalcTown 2017]. Orifices also come in many different shapes or categories. The most common of these is the sharp edged orifice which is a simple hole [lmnoeng 2016]. Other common orifices include smooth edged, short tube and borda which appears to be a short tube on the interior of the container. Each different hole affects the velocities and displacements of the jet as the jet is subjected to either more or less friction and drag through each different hole type [lmnoeng 2016]. This results in many different coefficients of discharge and velocity which can then be inserted into equations. The orifice types are displayed below. According to multiple experiments the average coefficients of velocity for each orifice have been determined. The orifices that will be used for this experiment are the Sharp edged, Short tube and Borda because the Rounded orifice is too hard to replicate using the resrouces on hand. The sharp edged orifice has an average velocity coefficient of 0.98 as well as the borda hole. The short tube has a velocity coefficient of 0.8 [LMNOeng 2016]. The equation that can implement this coefficient is a derivative of Toricellis The viscosity of the fluid can also affect a fluids flow displacement out of an orifice. Viscosity is defined as the resistance of flow and is the result of the interaction and friction between different molecules in a fluid, at a molecular level [rheosense 2017]. A substance that has high viscosity has high friction and flows through an orifice slowly, this in turn means that it would not be displaced very far from the hole, an example of this is honey [rheosense 2017]. Viscosity can be decreased with an increase in temperature [Viscopedia 2017]. Water however is said to have a low viscosity, so this temperature change theoretically should not affect its discharge to much which is why temperature will not be a variable that will be tested [Viscopedia 2017]. To determine each of the horizontal displacements that the jet will theoretically travel, the cross sectional area of the 1.25L soft drink bottle (A) needs to be calculated first through the simple area equation for a circle. This will be used universally to calculate the Velocity of Efflux. [Simson Rowland 2010] Since this first experiment is testing the displacement of water through a diameter change, the cross sectional area of the orifice (a) needs to be calculated next. The height of the surface as a variable is kept at a constant 0.012m, while for this example, the diameter of the orifice is 3.18mm. [Simpson Rowland 2010] Then the pressure at depth can also be calculated next from Bernoullis standard fluid equation and for this first experiment, the pressure determined will be the same for each hole size being tested. Assuming that the pressure at the surface of the fluid is 94500Pa, the density of water is 1000kgm-3 and the height of the surface above the orifice is 0.12m, the pressure of the fluid at the same level as the orifice should be given below. [Madden et al. 2004] A deviation of Toricellis equation can then be used to determine the velocity of efflux with in the jet. The value calculated can be used to determine the theoretical displacement of the jet. [CalcTown 2015] And now the maximum displacement the water is expected to discharge can be found using another deviation of Torricellis equation that has been rearranged slightly to fit requirements. Assume that the orifice height from the bottle is 0.19m above the location where horizontal displacement is measured (ruler). m [Calvert, J.B. 2003] Therefore based off theses assumptions and calculations, theoretically, when the jet starts flowing from a surface height of 0.12m and an orifice diameter of 3.18mm, the fluid should be displaced about 0.302m from the orifice. The theoretical displacements of the water are displayed in the table and graph below. Theoretical Displacement from Diameter Change (test 1) Diameter (mm) Velocity of efflux (ms-1) Displacement (m) 0.00 0.00 0.00 3.18 1.53 0.30 4.76 1.53 0.30 6.35 1.53 0.30 These displacements are the same, however by increasing the hole size, the displacement does increase however by not a large amount as displayed in the graph below. Due to background research above, the theoretical displacements of the water in experiment 2 can be determined from each of the heights that will be used. Beginning at the surface height of 0.04m, theoretical displacements can be determined from the following calculations assuming that the jet is not affected by air resistance and the pressure at the surface of the fluid is 94500Pa. [Madden et al. 2004] So the pressure at the hole should be 94892.4Pa. The velocity of the jet can then be calculated using the areas calculated before and the same deviation of Torricellis law. [CalcTown 2015] Using this value calculated, the horizontal displacement can be determined using the equation from experiment 1, still assuming that the height of the orifice above the location of measuring is 0.19m. [Calvert, J.B 2003] Therefore the expected horizontal displacement when the height of the surface is 0.04m is 0.174m. The other results calculated using these formulae are displayed in the table and graph below. Theoretical Displacement from Height Change (Test 2) Height (m) Velocity of efflux (ms-1) Displacement (m) 0.00 0.00 0.00 0.04 0.89 0.17 0.12 1.53 0.30 0.20 1.98 0.40 A new set of equations will need to be used to determine the velocity of efflux, seeing as the formulae previously used only factors in surface heights, orifice and bottle sizes. This formula will need to utilize the coefficient of velocity for each hole shape as this coefficient supposedly changes with a change in hole type. Beginning with the first hole, borda (interior tube), we will assume that the height will be 0.12m, air resistance does not affect discharge and the coefficient of velocity will be the same as the average researched for this hole, 0.98. A deviation of Torricellis equation will be used to incorporate this coefficient into calculating the velocity of efflux but first the pressure inside the bottle will need to be calculated. [Madden et al. 2004] Now the Velocity of efflux will be calculated as previously mentioned, also assuming the same factors previously mentioned. [LMNO Engineering, Research, and Software, Ltd 2015] Using this velocity, the expected horizontal displacement of the jet can then be calculated using the same equation and method used in previous tests. [Calvert J.B. 2003] Therefore the expected displacement the jet should be displaced using a Borda orifice is 0.296m, that is if all assumptions made come into effect in the experiment. All results calculated using this same format and assumptions are displayed in the table and graph below. The other orifice use different coefficients to be calculated, it is assumed that for the Sharp edged orifice, the velocity coefficient will be 0.98 like Borda, and for the short tube, the coefficient is 0.80.

Hamlets Procrastination And Co Essay -- essays research papers

Hamlet’s Procrastination and Cowardice  Ã‚  Ã‚  Ã‚  Ã‚  In William Shakespeare’s play Hamlet, Hamlet is a loyal prince who vows to avenge his father’s murder. When Hamlet discovers the painful truth about his father’s death, he is left with feelings of hatred and resentment in his heart towards the murderer, Claudius. Although Hamlet is a very noble and sophisticated man, he struggles with the issue of avenging his father’s death. He swears his revenge will be quick, however, this is not the case. Since Hamlet is more into philosophizing than action, he thinks about his intention to kill Claudius. The more he thinks about his intention, the less he is able to execute it. The tragic flaw that Hamlet possesses is his inability to act. He vows that he is going to kill Claudius but backs out of it several times before the deed is actually done. Hamlet’s first sign of procrastination and lack of action begins to show through his character at the very beginning of the play. The ghost informs him about Claudius’ evil doings. Hamlet is prompt by replying: “Haste me to know’t; that I, with wings as swift As meditation or the thoughts of love, May sweep to my revenge.'; (Shakespeare, p. 67) This passage shows how Hamlet decides to avenge his father’s death. In fact, he declares that he will be committed to nothing else but the revenge against Claudius:   Ã‚  Ã‚  &nb...

huckleberry finn :: essays research papers

In the story of Huckleberry Finn, Mark Twain uses many different types of symbols to get Twains numerous messages across. Twain signifies the Mississippi river as a symbol to get away from society for Huck and Jim. Twain also criticizes the way society runs and the things it teaches everyone to be. The river vs. land setting in Huckleberry Finn symbolizes Huck's struggle with himself versus society; Twain suggests that a person shouldn't have to conform to society and should think for themselves.Throughout the novel, Mark Twain shows the society that surrounds Huck as just a little more than a set of degraded rules and authority figures. When the new judge in town allows Pap to keep custody of Huck, adopters are things he doesn't need and doesn't care for. Twain gives Huck the power to think for himself, and come to adult conclusions, which show Twains message; think for yourself.Mark Twain's book Huckleberry Finn is for the reader to interpret for him or herself. But any reader cou ld pick up on Huck's struggle with the freedom the Mississippi River gives him, and the society that holds him back. Huck realizes that he shouldn't have to conform, and he refuses to at the end of the book. Huck's trials and tribulations show the reader that he or she to think for themselves and not conform to societies standards from Huck's time period, or now. Mark Twain creatively invents many settings throughout The Adventures of Huckleberry Finn; each setting effects the characters in different ways. One of the many motifs throughout the novel is the idea of freedom versus slavery. Through various incidents, lifestyles, and character developments taking place on land and water, Mark Twain is able to create two opposing worlds; i.e. one of freedom verses one of enslavement. Twain determines the characters' situations in life in accordance with each location and surroundings. Huck and Jim are constantly moving between these two worlds. For the most part, both are presented with the luxuries of freedom and serenity while on the river, which ends up changing both of their characters for the only as more of person, but a reliable friend. The reader gets a sense of Jim's kindness when he is willing to stand watch all night so Huck can get some extra rest.

Boston Massacre :: essays research papers

The town of Boston was a very uneasy city throughout the 1760's. This uneasiness quickly turned to belligerence in the early part of 1770. Tensions had been mounting from the beginning of the year with various clashes between British sympathizers and colonists. However, in early March the tensions erupted into bloodshed. On March 5, 1770 a small group of colonists were up to their usual sport of tormenting British soldiers. By many accounts there was a great deal of taunting that eventually lead to an escalation of hostilities. The sentry in front of the Custom House eventually lashed out at the colonists which brought more colonists to the scene. In fact, someone began ringing the church bells which usually signified a fire. The sentry called for help, setting up the clash which we now call the Boston Massacre. A group of soldiers led by Captain Thomas Preston came to the rescue of the lone sentry. Captain Preston and his detachment of seven or eight men were quickly surrounded. All attempts to calm the crowd proved useless. At this point, the accounts of the event vary drastically. Apparently, a soldier fired a musket into the crowd, immediately followed by more shots. This action left several wounded and five dead including an African-American named Crispus Attucks. The crowd quickly dispersed, and the soldiers went back to their barracks. These are the facts we do know. However, many uncertainties surround this important historical event: Did the soldiers fire with provocation? Did they fire on their own? Was Captain Prescott guilty of ordering his men to fire into a crowd of civilians?

Seed Germination

The time that a seed germinates, and whether or not it actually does germinate, depends on many factors. These factors include; the chemical environment, which must be the right conditions; oxygen must be present, and inhibitory chemicals must not be present. Germination also depends on the physical environment. Temperatures must be suited to the seed, and light quality and quantity must also be suited to the needs of the seed. In some cases, all these conditions are met, and still, the seed fails to germinate. This is because the seed is said to be dormant (Bewley and Black 1985). Seed dormancy is a short-lived deficiency, or block of an able seed to complete germination under suitable conditions. There are two different types of dormancy, embryo, and coat dormancy (Kucera et al.2005). Embryo dormancy is mostly common in woody species, but can also be found in blossoming plants as well. Coat dormancy is when the tissues that enclose the seed are too tight and the seed cannot overcome the constraint. Seeds can be released from dormancy through being chilled, sometimes for several weeks, or sometimes even months, at temperatures of one to five degrees Celsius. This means that seeds that rely on such ways of dormancy must wait for the cold seasons to pass before they can germinate (Bewley and Black 1985). Many seeds can germinate with, or without light, but the plants that require light, are called photoblastic, and are controlled by the phytochrome (Kendrick and Russell 1975). Phytochrome has two descriptions, the first one, Phytochrome red (Pr), is transformed by red light, to the second form, phytochrome far red (Pfr). Far red radiation can reverse the whole process. Phytochrome far red absorbs far red light (730nm), and phytochrome red absorbs red light (660nm) (Toyomasu et al. 1997). Seeds that are grown in darkness don’t germinate unless they are exposed to red light for a short period of time. For a red light to be effective, water content in the seed must be at 15%, because dry seeds do not respond to red light. In lettuce seeds that are matured naturally, phytochrome is most commonly in the form of phytochrome red, and in the dehydrated form, the conversion to phytochrome for red light is not possible (Kendrick and Russell 1975). Lettuce is an important vegetable cultivated worldwide, and requires high quality seeds. Lettuce seeds are unable to germinate in the dark, and are unable to germinate at high temperatures. These characteristics affect the rates that new seeds are developed (Metzger et al. 2009). Light is a very important factor in releasing seeds from dormancy. Seeds can be affected by being exposed to white light from just a few seconds, to or even minutes, others require intermittent light. The light frequency that is required depends on the temperature. Lettuce seeds that are bought in stores are usually treated to improve the germination process, even when lots of light is unavailable. Although, light sensitive leaves need a lot higher levels of phytochrome far red light to bring the seed out of dormancy (Kendrick and Russell 1975). Using all the information I have gathered, I hypothesised that the red light and white light would cause a greater percentage of germination than the other lights, because they produced more far red light. Methods The lettuce seeds that we used (Lactuca sativa L.cv Tango), were dried and stored at 22oC until we used them. We used gibberellin acid (GA3) of ≠¥ 90% purity, at the following concentrations; 10-3, 10-4, 10-5, and 10-6. The red light source we used was gathered by filtering white light that came from a twenty-five watt fluorescent bulb, through two layers of dark red cellophane paper. We got the far red light by a forty watt incandescent bulb. The light was then filtered through a container containing 10cm of water, which was placed above the two layers or red and blue cellophane. The white light we obtained was taken from a sixty watt light bulb. Twenty to thirty-five lettuce seeds were placed on two layers of whatman No. 1 filter paper, and all seeds were equally controlled in a room with a green light bulb. In each dish, 5ml of distilled water was added, along with 5ml of its appropriate GA3 solution. The dishes were wrapped in one layer of tin foil, and put in a darkened box. A control was also prepared. The seeds were added to a dish with distilled water. All the experiments were conducted at the same temperature, 24oC. When everything was ready, to figure out how many seeds were germinating, we counted how many seeds in each petri dish had a white radical coming out if it. When we were done, we recorded our results, and pooled them with the rest of the class (Migabo 2011).
