Bottle Rockets essays

Bottle Rockets essays To start this semester we started off with a bottle rocket project. This project lead us to become more educated with Newtons laws of motion. The bottle rockets also lead you to learn about mass, force, and acceleration. As you know the first law of motion is that if objects at rest will stay at rest, or objects in motion will stay in motion, unless acted upon by an unbalanced force. Well in order for the rocket to lift off it will need force applied to it. It is required to add water for your rocket and you dont want to add too much because then the rocket will be too heavy. As you told us in class the best thing to do is add a little at a time and test it. You want your rocket to be stable. The height and weight do matter but test as mush as possible to be sure it will work. The second law of motion is the acceleration of an object is directly related to the force applied on the object and oppositely related to the mass of the object. So this is based on the speed of the rocket. And the speed is also involved in what the weight of the rocket is and the force it has from the water. Because the mass and acceleration is being forced going up. The rocket needs enough force in order for it to take off. You cant have a huge mass and not enough force, because it will not work. And the third law of motion is, for every action there is always an opposite and equal reaction. So then when you have your rocket on the launch pad and all ready then its determining on the motion of the rocket being equal to and opposite from the nozzle. Like if the rocket goes one way and the water goes the other way. You want it to be centered and balanced. Figuring on how many times you have tested it will and can improve on your final launches. And then you will have a bigger idea on how the water being forced down is going to equal the force when the bottle goes up. And as conclusion, your best idea was a ...

Morepan Positioning Strategy Essay Example | Topics and Well Written Essays - 500 words - 1

Morepan Positioning Strategy - Essay Example From this discussion it is clear tha by entering into the distribution agreement with Geneva Pharma to be the sole supplier, the Company was able to provide a cost advantage to its customers. Moreover, in the case of bulk drugs, the Company has moved into high margin drug products where the multi -production processes are long and complex; however by developing the necessary technical capabilities to tackle such processes in a cost effective manner utilizing low labor costs in India and supplying to international markets, Morepan has been able to create economic value for its customers. According to the study Morepan has also positioned itself not merely as a bulk drug company in the Indian market, but has consolidated its position and created customer value by also entering into the Fast Moving Health Goods category. By hosting an entirely new range of products which could be directly marketed to the customers rather than having to reply upon physician prescriptions, the Company was able to gain direct access to the end customer unlike other drug companies. It developed a range of health products such as Lifelyte which was an electrolytic rehydrate, Y Sugar which was a sweetener, Dab fizz an antacid, and similar products which could directly be targeted at the end customer and marketed vigorously through effective sales and advertising techniques. In this way, the Company ha uniquely positioned itself in the market for health food products. Recently the Company has further expanded its reach into the retail sector in the health care market, through the creation of the Lifespring chain of health and beauty stores.

Database Systems Concepts Essay Example | Topics and Well Written Essays - 750 words - 1

Database Systems Concepts - Essay Example An operating system should aim for two things: It should manage input and output devices, and it should control, supervise and empower (which each have separate sub-goals and are sometimes in conflict) users as well as administrators and people connected on the network to use the hardware to run software. Efficiency helps these goals because it reduces lag in input and output and because it reduces the overhead of the OS thus allowing people to run more programs and run them with less slowdown and issues. However, it is unquestionable that DOS would be far more efficient than Windows 7. Assume for a moment that a DOS-like text-only input with no or few visual input systems could run every element of modern software. Most consumers would still prefer not to spend their time mucking about in command prompts unless it's absolutely necessary. Similarly, Linux users often get better machine-specific functionality by compiling their own kernel, but for most users, â€Å"good enough† is better because an OS like Windows designed to run on the lowest common denominator takes more of their time. Very few people like to struggle with computers: They want to quickly install the OS and get to work on what they're doing. Their time is valuable either to them or to their organization, and so it's actually inefficient to waste their time with OS â€Å"efficiency†. User friendliness is one of the keys to the success of Macintosh. Many experienced PS users smart at Macs because they feel that they are being too constrained, but they are often lifetime computer users. Many people don't have the temperament or interest. â€Å"Efficiency† in the form of less graphical displays and overhead is wasteful for these customers because that overhead gives them a better, more pleasurable and more efficient experience. Power consumption is another area where OS overhead could be acceptable. Controlling for power does cost computational time, but it also saves customers money. On laptops in particular, having power management tools, which are an additional process running and thus introduce inefficiencies and bloat as well as risks of system failure in terms of power consumption software errors, are worth it because they allow users more time with their laptops. Allocational tools can also introduce temporary overhead, but if customers are intending to run dozens of programs, as most are, having smart allocation is an investment that pays off. In fact, many OS tools are basically investments with short-term inefficiencies that lead to long-term computational efficiency. Drivers with video cards, for example, clearly cost some degree of computational time and lead to bloat (and anyone who has struggled with failing drivers or Direct X compatibility issues knows that errors in these arenas can be catastrophic), but they allow the usage of additional RAM devoted to graphical elements which is necessary to run most modern games or modeling software. O ne of the more controversial elements of system overhead is security. In essence, many OS designs don't trust their end user to be safe. Firewalls with highly restrictive settings, anti-viruses that are hard to get rid of, built in anti-spyware, permissions management systems... these improve security, with some risk of exploitation (since every security measure can also be a security loophole), for the lowest common denominator user with little skill

Jaguar Land Rover plc - Essay Example JLR has managed to capture markets in North America, UK, Europe and China. JLR has a large sales and distribution network. Jaguar and Land Rover compete in 101 and 174 respectively. Its large distribution network comprises of 18 National Sales Companies, 61 export partners, 83 importers and 2,241 franchise dealers. (JAGUAR LAND ROVER PLC. 2011; BANERJEE, B. 2008) Financial Results: JLR Plc has shown improvement in its financial results over the years. In 2008 when it was acquired it was a loss making company, with the improvement in technology, cost cutting strategies, increased volume, product and market mix and favorable exchange movements Tata Motors has managed to make JLR Plc a profitable business for the group. In 2011, due to its expansion in new markets of China and Russia where demand of premium cars was high, helped improve the company’s performance. An increase in revenue- retail and wholesale both, earning before interest, tax, depreciation and amortization (EBITDA ) and net income have also been recorded in 2011 as compared to previous financial years due to efforts made in development of new products, entering new markets and resulting increase in volumes, decrease in costs and better working capital management. (JAGUAR LAND ROVER PLC. 2011; BANERJEE, B. ... Information could be required about ROI, RI, payback periods of a product etc. Mangers require financial information like revenue and costs to determine profit. In this analysis cost of goods sold is involved which is closely related to inventory management that is an important aspect of management’s work. In an automobile business like JLR inventory management and valuation (completed products and work in progress) is the key to success, holding large inventory increases cost or keeping less inventory results in stock outs, both effecting customers. (DRURY, C., & DRURY, C. 2005) On the other hand JLR managers need information to take routine decisions and also strategic long term decisions. Information is required relating to profitability to know which products to retain and which should be abandoned. Cost information is crucial aspect of the business too. Based on this information managers take decisions about company’s cost cutting strategies and enables them to com pete in highly competitive markets. (DRURY, C., & DRURY, C. 2005) Activity Based Costing: Cost information and its analysis is an important aspect of any business to gain a competitive edge over other business. The breakup of costs and easy, fairer allocation of costs incurred can provide a true picture about the profitability of the products. In automotive business like JR Plc, a large portion of costs are incurred in administrative activities which are difficult to apportion directly to the products. ABC can change the way organization measure their performance and view their performance. (ANDERSON, S. W., & YOUNG, S. M. 2001) Data collection and employee

Seawater Composition and Salinity :: Tides and Salinity

Using the decanted supernatant solution from the precipitation experiment, a wire loop was dipped into the solution. This loop was stuck in the flame from a Bunsen Burner and heated until a flame appeared. The presence of a bright yellow flame confirmed that Na+ was in attendance. Using a cobalt glass as a filter, the loop was examined and a violet flame was present, showing that K+ was also in the supernatant solution. Testing for NH + This test was carried out using the original solution to avoid contamination of ammonium salts from the other procedures. 0.1M NH4CL and DI water were added to a large well on the micro drop tray before drops of 6M NaOH were added. A piece of red litmus paper was put on top of the well and covered with a watch glass. The appearance of an unmarked blue color, a direct result of the release of NH3 gas, on the paper confirmed the existence of NH4+. The experiment was repeated using seawater instead of the 0.1M NH4CL and DI water combination. ! Quantitative Pre-Gravimetric Set Up Test tubes were obtained and labeled using a bl according to which test the sample was intended for Barium) and what depth the sample was obtained at or bottom).All the test tubes were put in a beaker and an oven at 110˚C for half an hour to dry. Once dry th removed and allowed to cool on a test tube rack, as Figure 1: Test tube rack with test tubes Figure 1, before being weighed and their weights rec Silver Halides Gravimetric Analysis The tests tubes labeled ‘Halides Top’ and ‘Halides Bottom’ were taken and 1mL of seawater was added to each. The test tubes were then weighed and their new weights recorded, before 6M Nitric Acid (HNO3) was added to each to acidify it. 0.1M Silver Nitrate (AgNO3) was introduced, causing a white precipitate to form. The solution was stirred with a glass rod and centrifuges for approximately a quarter of an hour. Once complete, another series of drops of 0.1M AgNO3 were added to ensure complete precipitation and the solution was recentrifuged for several minutes. The supernatant solution was decanted into a wast container and DI water was mixed into the precipitate to clean it. The solution was centrifuged, supernatant decanted, and rinsed with DI water once more before being centrifuged and the aqueous solution decanted for a final time. The test tubes were then returned to the beaker and placed back into the oven to dry for a week.

Hybrid Informative

Speech Assignment: Informative #2 Speech Goal: To inform the audience on hybrid cars. Opening: Hybrid cars are much more environmentally friendly than gas only vehicles. There are several different sorts of transportation that one would have never thought of as being hybrid. There are plenty of advantages of having a hybrid over gas only and electric only cars also. Body: 1. What is a hybrid? * 2 or more sources of power that can directly or indirectly provide power. * It usually is a vehicle that is both gasoline and battery powered 2. Types of hybrid’s? Mopeds * Combines power of gas engine with pedal power rider * Locomotives * Pulling trains are diesel-electric hybrids * Buses like Seattle are diesel-electric * They can draw electric power from overhead wires or run on diesel when they are away. * Mining trucks * Diesel-electric * Submarines * Some are nuclear-electric and then some are diesel-electric 3. Kind of hybrid’s? * Series hybrid * Does not have direct conn ection between the engine and the wheels. The engine drives a generator, and then provides electric power for either the batter or the motor. Cylinder to generator or fuel tank; generator to battery or motor; which then transmission * Parallel hybrid * Use electric motors to assist the engine in driving the wheels through the transmission. * Fuel tank supplies gas to the engine and battery that supplies power to the transmission. 4. Advantages? * Verses gas-only modes, hybrid cars gas efficiency double them which provides a significant amount saved * Less pollutant during use – burn less fuel – when being build they were conscious of environmental pollution so they make the vehicles much cleanerClosing Hybrid is the best way to go when you’re choosing a vehicle; it is the best of both gas only and electric only cars. They are even built better than the gas only cars that most of us have. When I get my next car I want a hybrid car for these exact reasons that I h ave stated.

A single gene disorder Free Essay Example, 1000 words

Those who carry two SS alleles suffer from sickle cell anemia (Human Genome Project Information, 2008; Genetics, 2000; Gene Gateway- Exploring Genes and Genetic Disorders, 2005; Gene Gateway- Exploring Genes and Genetic Disorders, 2003). Inheritance pattern of sickle cell trait/disease When both the parents are carriers of the sickle cell disease (carry one normal and one abnormal allele), each of their children have a 25% chance of inheriting two normal genes; 50% chance of inheriting one normal and one abnormal gene and thereby would only be carriers of the sickle cell trait. There is a 25% chance that each child might inherit both the abnormal genes and become individuals with the sickle cell disease (Gene Gateway- Exploring Genes and Genetic Disorders, 2005; National Heart Lung and Blood Institute). The inheritance pattern for the sickle cell disease can be illustrated as follows In the mutated S allele, a point mutation results in the insertion of a hydrophobic valine amino acid instead of the normal hydrophilic glutamic acid in the ÃŽ ² globin gene of the hemoglobin moiety (HBB), found in the short arm of chromosome 11.We will write a custom essay sample on A single gene disorder or any topic specifically for you Only $17.96 $11.86/pageorder now The genetic location of the HBB gene is shown below This insertion results in a change in the three-dimensional structure of the hemoglobin protein upon unloading the oxygen to the tissues resulting in clumping together and sickling of red blood cells (Genetics, 2000; Gene Gateway- Exploring Genes and Genetic Disorders, 2005; Gene Gateway- Exploring Genes and Genetic Disorders, 2003). Mechanism of action The severity of the disorder is most prominent among individuals who carry the recessive allele (SS). The substitution of the hydrophobic valine amino acid results in the presence of an outer hydrophobic region that causes the adjacent hemoglobin molecules to stick to each other. Thus the hemoglobin molecules polymerize, after unloading oxygen to the tissues, to give rise to rigid or rod-like structures that eventually leads to sickling of the cells. When these molecules return back to the lungs for oxygen uptake they depolymerize and assume their native structure. This repeated shunting in their structural configuration leads to rigidity of the cells and in this state they can cause blockages of several small blood vessels which they might enter. This finally leads to oxygen deprivation of the tissue, pain and tissue/ organ damage. In addition to the above, sickling also results in a decrease of the life span of the red cells.
