...The Day After Tomorrow is a movie that stars Dennis Quaid, Jake Gyllenhaal, and Emma Rossum and was directed by Roland Emmerich. The movie is based on a paleoclimatologist that treks across America to save his son who is trapped by a sudden international storm that plunges America into a new Ice Age. I liked this movie for many reasons, but it had some draw backs. Summary In the beginning of the movie Jack Hall (played by Dennis Quaid) is at the North Pole drilling core samples for research on global warming. As they are drilling into the ice getting samples, the ice starts to split leaving a very large valley in the ice and some of the samples could be left behind. Jack makes a daring leap across what seems to be a 7 foot crevice in the ice. He makes it across and gets the samples but as he is about to leap back across to the safety of his colleges the ice splits again, and he narrowly escapes falling in the crevice. After getting the samples back to the lab and testing them he realizes that there is an issue with the samples and also that there was a sheet of Ice the size of Texas that broke off, so he goes to a convention to warn other people of the facts that he has learned. Discussion One thing that I liked about this movie is the snow. The fact that the frigid cold could freeze your skin, crystalize your lungs, freeze Jet fuel at -200 Fahrenheit in a matter of seconds. Also it froze the ocean solid enough that it could be driven on and walked upon. It...

...1. A batch process is used. A worker checks the master list for ingredients, and enters that information into the computer. The computer determines ingredient quantities, and then automatically orders the ingredients, which are automatically sent to mixing machines. After mixing, the batter is poured into a cutting machine. Individual cookies are then dropped onto a continuous band and transported through an oven. Filled cookies require an extra step. After baking, cookies are cooled on a spiral cooling rack. Cookies are inspected, defectives are removed and the remaining cookies are packaged and labelled. 2. The use of automation in the mixing process resulted in a reduction in waste; cookies are cut on a diagonal; and the company recently increased the length of its ovens (i.e., more cookies can be baked at the same time).3.All companies have a moral obligation to their employees. Small companies with local owners, particularly in a small community, are more likely to be influenced by such considerations than large companies, in large communities, even with local owners, and even less likely to be influenced if owners are distant, or uninvolved in operations. The issue is a difficult one, often without easy solutions. Cost and efficiency may favor layoffs, but ill will and the effects on morale of employees that remain are important considerations. 4. Freshness of cookies, frequent changes of label requirements, and baking to customer order are factors that favor minimal inventories...

...1. The process is a batch processing system of two band ovens. A list of cookies is delivered to the worker who is in charge of mixing the ingredients. The worker will carefully check the list and enters the list into the computer. The computer will automatically determine the list of ingredient portions and the ingredients are automatically ordered and sent to the mixing machines. When the batch is stirred completely then it will be sent to the cutting machine. The cookies are then dropped to the oven and if the cookies have fillings such as apples, dates, and raspberries an additional step is required. Once baking is completed the cookies are then cooled to a spiral cooling rack. The cookies are then thoroughly inspected and cookies that are defected are removed and the cookies that remain are then package, sealed and sent out. 2. Everything is automated and most of the cookies are non-filled and cut diagonal rather than round. This will cause less waste since they are cut diagonal. And the company place spending on extending the size of the oven by 25 feet. More cookies can be baked at one time which will increase production. 3. The company is making the right decision by manually packaging the cookies by workers. Packaging automatically can cause issues in the amount of cookies being distributed or defective cookies may not be detected at times. Efficiency may not play an excellent role in packaging if automation is used. All companies have an ethical...

...Hallee Callizo English 101/Dahlman Final Essay 2 13 March 2015 In John McPhee’s, The Control of Nature he talks about how no matter what you think should happen nature will continue doing things in its own way. In the chapters“Cooling the Lava” and “Los Angeles against the Mountains” the situations and catastrophes that have caused harm to these places demonstrate that Mother Nature has its own way of life and people cannot simply stop what is happening. With McPhee telling his readers that people who try to change or stop nature need to realize that this attempt is futile, because humans cannot control nature. They cannot stop the volcanoes from erupting lava or can we stop the boulders from falling down the mountain. In the book/monograph/treatise, in the chapter “Cooling the Lava” Thorbjorn, who is a native from Iceland has this idea that he will stop the lava from flooding by cooling. With his logic of cooling the lava, the water would reduce the heat in order to create a wall of cooled lava that would dam the flow. “The lava should be cooled not so much by the edge as by the acre, and that called not only for more pumps but also for the development of material and personnel up on top of the advancing flow”(McPhee 98). With this being said, it should be obvious that humans cannot be the ones to stop Mother Nature. The destruction the lava has made is a big mess we face. It is destroying the homes of many people, but that is only affecting the people who live there...

...Resume When loading, is about one-third of the energy lost and is converted into heat. You can change the number of times you can load calculate as follows. Loading times = battery capacity power bank / battery capacity smartphone x 0.65 You need the capacity to calculate simple with the following formula. Battery capacity power bank = number of times the battery x battery capacity smartphone / 0.65 smartphone usage The number of times you need to charge your smartphone each day depends greatly on how you use your smartphone. With average use, this is a once a day. Do you use your smartphone intensively, such as a festival where we make a lot of pictures and videos, it can take up to two or three times a day. The battery capacity of smartphones running by brand and model range stretching from 1500 mAh to over 3,500 mAh. Consult the manual or search it on the Internet. Conclusion Power Bank are available with different battery capacities. Which capacity is best for you depends on several factors. The number of days you want to charge your smartphone without seeing an outlet. How intensively you use your smartphone The battery capacity of your smartphone.

...refrigerants are instruments used either for heating or cooling, although the main application here is cooling. The combination of solid state rrefrigerants, water based heat transfer fluids and high efficiency fluids leads to environmental freindly products, which minimizes contribution to current global warming issue. The magnetocaloric effect was originally found in the 18th century, by E. Warburg (1881) in pure iron, where the cooling effect only varied between 0.5 to 2 K/T. Then in the late 1920s, major advances appeared when two scientists: Debye (1926) and Giauque (1927) proposed cooling via adiabatic demagnetization. A few years later in 1933, Giauque and MacDougall demonstrated the process for cryogenic purposes and managed to achieve a temperature of 0.25K (Cryogenic meaning the study of the production of very low temperatures and behavior of materials at those temperatures). Advances occurred through the years up to 1997, until the first near room temperature proof of magnetic refrigerator concept was demonstrated by Professor Karl A. Gschneidner, Jr. from Iowa State University. This discovery drew attention and interests from scientists and companies worldwide. Since then new kinds of room temperature materials and magnetic refrigerator designs have developed. In this modern era, reliable cooling technology is highly demanding. Refrigeration plays an important role in the societies’ health as well as the global economy. The modern refrigeration is based on a compression/...

...------------------------------------------------- Thermal pollution Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition.Urban runoff–stormwater discharged to surface waters from roads and parking lots–can also be a source of elevated water temperatures. When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt change in water temperature known as "thermal shock." ------------------------------------------------- Ecological effects Warm water Elevated temperature typically decreases the level of dissolved oxygen of water. This can harm aquatic animals such as fish, amphibians and other aquatic organisms. Thermal pollution may also increase the metabolic rate of aquatic animals, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed.[4]:179 An increased metabolic rate may result in fewer resources; the more adapted organisms moving in may have an advantage over organisms that are not used to the warmer temperature. As a result, food chains of the old...

...concerned with the heat generated by an LED lighting load and its dissipation to the surrounding such that the LED junction temperature is maintained low. The LED chosen for this project is 7.5 Watt, which has a maximum operating temperature of around 80°C, exceeding which the LED will fail. The LED is best operated at room temperature conditions and may be just above. The project implements a specific method of cooling or rather maintaining the LED junction temperature as low as possible by using a Thermo Electric Cooling device, more specifically known as the Peltier device. The project looks into the various methods by which a Peltier cooler can be implemented such as, with or without a fan or simply a fan would provide sufficient cooling for the LED module.
