CHEMISTRY IN LIFE Charles Barker CHM/110 7/6/2015 Subhashis Nandy Introduction When living in a world such as ours, chemistry plays a large role in how society interacts. Chemistry can be viewed from many different angles because of its dynamics when dealing with the nouns of life (People, places, and things). With people, chemistry is how he or she connects to their social conformity. With places, chemistry is the structure and atmosphere that brings about the culture to the arena. With things, chemistry is the accuracy and measurement that brings the degree of closeness to the true value of its quality. In this paper, one will cover chemistry in terms of accuracy and precision, the relation to scientific methods, and how†¦show more content†¦What it comes down to is supply and demand and the chance to retain a profit from the precision of the weight and how much to distribute of an item in most situations. Another angle to which society depends of accuracy and precision of measurement are within the food market. It is important to understand how to order in quantity that will last from one month to the next. The scientific method A scientific method is a way to ask questions and answering them by making observations and doing experiments. The steps of the scientific method are: Ask a question, do background research, construct a hypothesis, test the hypothesis by doing an experiment, analyze your data and draw a conclusion, communicate your results. When looking at these steps the explanation of them are rather simple. To ask a question means to open the floor for discussion to gain an answer. Once he or she gains the Intel, he or she will perform a background research to be sure that the information is credible. From here, one will construct a hypothesis as to why things are the way they are. This will lead to predictions that can be tested in multiple ways. Then one will test the hypotheses by doing a experiment. The modern interpretation of this test often times will show that the hypotheses must be falsifiable which means that there are possible ways to identify the outcome of theShow MoreRelat edWhat Is Blood Chemistry?1122 Words   |  5 PagesWhat is blood chemistry?

Multiprocessor And Multi-Core System On Operating System

Question: 1. The four (4) main components of a computer system are: Processor: controls the operation of the computer and performs its data processing functions Main memory: stores both data and instructions; I/O modules: which move data between the computer and its external environmentSystem Bus: provides for communication among processors, main memory, and I/O modules Which of the above 4 components do you believe is most important? Why? 2. How would you distinguish between a multiprocessor system and a multicore system? Which system you believe is more efficient? Why? Answer: Task 1: Main Component of Computer system The processor is the main component of the computer system in comparison to main memory, I/O modules and system bus. The processor is useful in managing the operation of the computer system. The operation such as arithmetic and logical operations are performed under processor. The processor is also termed as central processing unit (CPU) (Hsiung Shen, 2010). In CPU, the data and instructions are taken from the storage unit and perform all calculations on the basis of instruction provided. On the other hand, the processor is useful in running the multiple programs at one time (Bolc, 2012). The processor allocates the certain percentage of space for every program and helps in pacing up the program. Moreover, the processor can instruct the computers to provide quick and accurate decisions to the users of computers. The capacity can be increased for analyzing the data and boosting up the computers. Therefore, many people consider the processor before buying personal computers (Hsiung S hen, 2010). For instance, todays computers are considered for gaming purpose. Therefore, customers look for processors that can provide different power level in computing. According to Hsu (2010), the processors is the brain of the computer system that transforms input instruction that is arithmetic, logical operations and control operations into output. Therefore, many processors making companies such as Intel regularly makes advancement in the processors. One or more printed circuit boards are needed for processors in case of large machine (Hwang, 2010). On small workstations and personal computers, CPU is built in single chip. Apart from that CPU is better than main memory because main memory requires continuous supply of power and it can be slower. Apart from that, the I/O modules is less important than processor as the speed of I/O device is slower than CPU and on the other side, the I/O module can slower down the speed of processor of CPU (Kumar et al. 2012). Moreover, processor is effective than system bus as system bus requires clock speed which I much slower as against CPU. Therefore, CPU can be regarded as the main component as it does all th e important work of the computer and all the input and output is based on the result of processor (Yeo et al. 2012). 2. Distinguish between multiprocessor system and multi-core system In multiprocessor system, the processors are located in different chips and processors are interconnected via a backplane bus. The multiprocessor can be helpful in enhancing the performance of the computer system with high speed and accuracy and it may require lower power consumption (Nicolescu Mosterman, 2010). On the other hand, the multi-core system has processor on the same chip. A multi-core system comprises I/O interface, interconnection network, shared memory modules, etc. Apart from that, multiprocessor has two or more than two physical CPUs and each CPU has one or more than one cores. In case of multi-core system, the only one physical CPU is linked with the CPU but can have more than one core in the central processing unit. On the other hand, in case of multi-core system does not require supply of power to every CPU in comparison to multiprocessor (S Suresh Kumar, 2013). Moreover, multiprocessor system allows CPU to perform work in parallel that is simultaneous multiprocessing whereas, multi-core system linked with multiple execution cores and CPU perform in parallel on different operations which is termed as chip-level multiprocessing. Multi-core system Multiprocessor system Processor power consumption Low High Processor Performance Low High Total Power Consumption Relatively low Relatively high Integration level All processors are on the same chip Each processor has different chip If selection is to be made between multiprocessor and multi-core system, then multi-core system can be much effective than former. The processing speed can be increased as total cores act as a processing unit. On the other hand, if the multi-core system is used, then CPU can deliver and process more data with the same rate of clock frequency. Therefore, it can be helpful for the users to take quick decisions. The employment of multithread with single core can be done with much ease with the multi-core processors (Uuz, 2012). On the other hand, the complex task can be easily performed by the CPU and also at low energy consumption. Therefore, the burden from power can be reduced and more number of tasks can be done in quick time. The CPU cache memory can be shared by multi-core system and separate use of cache can be reduced for each core. The computer can work faster in case certain programs such as web browser, office suite, video games, etc (Xu Ge, 2012). On the other hand, the com puter may not get high heated whenever the computer is turned on. References Bolc, L. (2012). Computer vision and graphics. Heidelberg: Springer. Hsiung, P., Shen, J.

Pasteur Essays - Grand Croix Of The Lgion Dhonneur, Louis Pasteur

Pasteur PASTEUR, Louis (1822-95). The French chemist Louis Pasteur devoted his life to solving practical problems of industry, agriculture, and medicine. His discoveries have saved countless lives and created new wealth for the world. Among his discoveries are the pasteurization process and ways of preventing silkworm diseases, anthrax, chicken cholera, and rabies. *BR* Pasteur sought no profits from his discoveries, and he supported his family on his professor's salary or on a modest government allowance. In the laboratory he was a calm and exact worker; but once sure of his findings, he vigorously defended them. Pasteur was an ardent patriot, zealous in his ambition to make France great through science. *BR* *BR* *BR* Scholar and Scientist*BR* Louis Pasteur was born on Dec. 27, 1822, in D?le, France. His father was a tanner. In 1827 the family moved to nearby Arbois, where Louis went to school. He was a hard-working pupil but not an especially brilliant one. *BR* When he was 17 he received a degree of bachelor of letters at the Coll?ge Royal de Besan?on. For the next three years he tutored younger students and prepared for the ?cole Normale Sup?rieure, a noted teacher-training college in Paris. As part of his studies he investigated the crystallographic, chemical, and optical properties of various forms of tartaric acid. His work laid the foundations for later study of the geometry of chemical bonds. Pasteur's investigations soon brought him recognition and also an appointment as assistant to a professor of chemistry. *BR* *BR* Pasteur received a doctor of science degree in 1847 and was appointed professor of chemistry at the University of Strasbourg. Here he met Marie Laurent, daughter of the rector of the university. They were married in 1849. Pasteur's wife shared his love for science. They had five children; three died in childhood. *BR* *BR* *BR* *BR* Research in Fermentation and Souring*BR* In 1854 Pasteur became professor of chemistry and dean of the school of science (Facult? des Sciences) at the University of Lille. Hearing of Pasteur's ability, a local distiller came to him for help in controlling the process of making alcohol by fermenting beet sugar. Pasteur saw that fermentation was not a simple chemical reaction but took place only in the presence of living organisms. He learned that fermentation, putrefaction, infection, and souring are caused by germs, or microbes. *BR* Pasteur published his first paper on the formation of lactic acid and its function in souring milk in 1857. Further studies developed the valuable technique of pasteurization (see Dairy Industry). The same year he was appointed manager and director of scientific studies at his old school, the ?cole Normale Sup?rieure. During the next several years he extended his studies into the germ theory. He spent much time proving to doubting scientists that germs do not originate spontaneously in matter but enter from the outside. *BR* *BR* *BR* Developing Cures for Agricultural Diseases*BR* In 1865 Pasteur was asked to help the French silk industry, which was near ruin as a result of a mysterious disease that attacked the silkworms. After intensive research, he discovered that two diseases were involved, both caused by bacteria on the mulberry leaves that provided food for the worms. The diseases were transmitted through the eggs to the next generation of worms. Pasteur showed the silkworm breeders how to identify healthy eggs under the microscope, how to destroy diseased eggs and worms, and how to prevent formation of disease bacteria on the mulberry leaves. *BR* At 45 Pasteur was struck by paralysis. For a time recovery was uncertain, and he was confined to bed for months. The attack left its mark; for the rest of his life, one foot dragged a little as he walked. *BR* *BR* In 1877 Pasteur began to seek a cure for anthrax, a disease that killed cattle, sheep, and other farm animals. He drew on research he was conducting on another animal disease, chicken cholera. When he inoculated healthy chickens with weakened cultures of the cholera microbes, the chickens suffered only a mild sickness and were thereafter immune to the disease. Pasteur successfully applied this technique of immunization to the prevention of anthrax. *BR* *BR* Many scientists challenged Pasteur's anthrax prevention claims, and Pasteur agreed to a dramatic test. Forty-eight sheep and a few cows and goats were gathered in a pasture near the town of Melun.
