Sovereign State and General B. Write

?The diagrams provide some information about the housing prices of 5 cities around the world from 1990 to 2000. Summarize the information by selecting and reporting the main features and make comparisons where relevant. The two column graphs illustrate the variation and differences in accommodation prices in 5 cities in 2 periods 1990 to 1995 and 1995 to 2000. Overall, while San Francisco and Beijing experienced a long period of stable growth, Rome saw a constant decline; Hong Kong and Sydney were subject to price fluctuations. With regard to San Francisco and Beijing, the 2 cities witnessed the climb in housing prices over the ten years of the investigation. In the first half of 1990s, this figure rose by 2%…

Clothespin lab

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally, muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the blood can supply. At this point the muscle is forced to produce ATP without oxygen. This is known as anaerobic respiration. Anaerobic respiration produces only 2 ATPs for each molecule of glucose. The result of this reaction is lactic acid. The advantages of…

IB biology IA respiration

Yeast are eukaryotic microorganisms just like other organisms, they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration, enzymes that are often found in the matrix of the mitochondria are used to speed up reactions in the body by reducing a reaction’s activation energy, which means that less energy is required to start a reaction. Enzymes need to collide with their respective substrates in order…

Tree Plantations

For over 10,000 years, man has been the greatest factor affecting biodiversity through habitat destruction and fragmentation, overexploitation and pollution. With an ever increasing population and human activities, man is consuming more and more natural resources by increasing the use of energy, fuel, and production of consumer products that are not necessarily needed. Man is very egotistic and believes that he owns everything that he has discovered; using most of the natural resources for self aggrandizement, without due considerations to the environment, ecology and other species that can only survive in their natural habitat. However, men are more inconsiderate than others about other organisms and the environment. In some places, some work hard to make changes into their lifestyles and…

Bio fuels essay. Biofuels are Fuels made from Biomass

Biofuels are made from plants,animals, or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which then can be used straight into central heating systems. 4 It can also be used as fuel for transportation such as specially designed cars with engines that run on biogas. 1 Biodiesel is an alternative fuel, similar to regular diesel,…

Global Warming : causes, effects and remedies

Global warming is the greatest challenge facing our planet. It is, in fact, the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. In short, global warming represents a fundamental threat to all living things on earth. Global average temperature rose significantly during the past century. The prevailing scientific view is that most of the temperature increases since mid-20th century has been caused by increases in atmospheric greenhouse gas concentrations produced…

Mis650. Data Centers

1. PUE (Power usage effectiveness), the ratio of total facility energy to IT equipment energy within a data computer, which measures how much of the power is actually used by the computing equipment. It is an important place to start when considering how to reduce data center power consumption because it is one of the most effective metrics for measuring data center energy efficiency. PUE is calculated by taking the total power of consumed by a data center facility then dividing by the power consumed by the IT equipment. In practical terms, a PUE value of 1 means that all power going into the data center is being used to power IT equipment. Anything above a value of 1 means…
