...greenhouse gases. Greenhouse gases are natural gases such as CO2, Nitrous Oxide or Methane and are created in one of two ways. The first way is, through natural cycles, for instance, CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic Climate Changes are changes in the atmosphere brought on by human activity, and there is evidence of these kinds of changes all over. By studying the size of the polar ice caps we can see that they are shrinking and this may be due to a warmer atmosphere temperature brought on by none other than an anthropogenic climate change. An IPCC report from 2007 showing levels of some of the greenhouse gases also shows that the levels of greenhouse gases in the earth’s atmosphere has skyrocketed since the post-industrial era, this can only be attributed to man-made machines that have come to rise. So how does human activity attribute to the climate rise? Greenhouse gases are natural occurring gases that hold in some of the heat energy that comes from the sun and bounce off of the earths’ surface; it’s not that these gases are bad in nature, we actually depend on them to keep the climate of our earth at a sustainable temperature, with that being said though, they are only positive for our atmosphere in moderation. In nature the gases such as CO2, Nitrous Oxide and...

...Clean Water Project Report Day 1- “The Balanced Equation” Documentary Notes In the documentary, “The Balanced Equation”, a group of high school girls tells their story of traveling to Kenya and the Dominican Republic to investigate and learn more about issues dealing with water in developing countries. The girls focus primarily on problems with water that exist in these countries and the water filtration systems being provided. According to the video, approximately 3.5 million people die from water-related illnesses each year, and over 800 million people do not have access to clean water today. The girls discover that portable point-of-use filtration devices are given to those in developing countries who don’t have access to clean water. Permanent water solutions, such as digging wells, have been tried, but often fail due to lack of maintenance and education. Wells often become contaminated with runoff water among other issues, so over 50% of these permanent solutions fail after 5 years. Instead, point-of-use water systems are distributed since they are portable and can be used at home. The girl’s spent their first night of their adventure in...

Amin In order to resolve the problem of low thermal and chemical stability of thermoplastic elastomers, dynamic vulcanization techniques were used in late ] plastic. In dynamic vulcanization the thermoplastic and elastomers are both cross-linked and physically mixed together. This gave rise to a second generation of thermoplastic elastomers which had better tensile strength and oil resistance as compared to those formed by physical mixing only [8]. ] ] ] _ were introduced which were made by same dynamic vulcanization process but using natural and butyl rubbers in place of EPR and EPDM. Natural and butyl rubbers have the advantages like low cost, very good over molding properties, reusable and very easily recyclable scrap [9,10]. Butyl rubber based thermoplastic elastomers have excellent adhesion with other thermoplastics hence it is still used to date for many over molding applications [11].

...The Discussion should be written after the Results section so that you have a good idea of what the experiment has demonstrated. The discussion section should definitely have a statement of your expected findings (Pechenik, 86). This should include your hypothesis and a brief statement about why these types of results are expected. There should also be a comparison of how your actual results related to your expected findings (Pechenik, 86). Here, you should state whether or not your results supported or didn't support your hypothesis. In addition, the degree to which the evidence supported your hypothesis should be stated. For example, were the results completely supportive, or were there variances? There should be an explanation of unexpected results (Pechenik, 86). When looking for possible explanations, consider the following: Was the equipment used adequate for the task? Was the experimental design valid? Were the working assumptions made correct? A common mistake that many writers make is to blame themselves for the unexpected results. Unless you actually made a mistake following the methods of the experiment, and could not go back and correct it, do not make up such errors to explain the variances you observe. Think about and analyze the methods and equipment you used. Could something different have been done to obtain better results? Another possibility to consider is if the experiment was conducted under factors that were considerably different from those described...

...Environmental Science Table of Contents Lab 2 Water Quality and Contamination 21 Water Quality and Contamination Concepts to Explore • Usable water • Ground water contaminates • Ground water • Water treatment • Surface water • Drinking water quality Figure 1: At any given moment, 97% of the planet’s water is in the oceans. Only a small fraction of the remaining freshwater is usable by humans, underscoring the importance of treating our water supplies with care. Introduction It is no secret that water is one of the most valuable resources on planet Earth. Every plant and animal requires water to survive, not only for drinking, but also for food production, shelter creation and many other necessities. Water has also played a major role in transforming the earth’s surface into the varied topography we see today. While more than 70% of our planet is covered in water, only a small percent of this water is usable freshwater. The other 99% of the water is composed primarily of salt water, with a small percentage being composed of 23 Water Quality and Contamination glaciers. Due to the high costs involved in transforming salt water into freshwater, the Earth’s population survives off the less than 1% of freshwater available. Humans obtain freshwater from either surface water or groundwater. Surface water is the water that collects on the ground as a result of precipitation. The water that does not evaporate back...

...Intermediate Disturbance Hypothesis Background Habitats and the ecological communities they support are often greatly impacted by disturbance. For example, forest communities can be disrupted by fires, blow-downs, floods, and hurricanes. Alpine plant communities can be devastated by landslides or avalanches. Marine systems such as coral reefs can be decimated by storms, ravaged by predators, or trashed by inconsiderate tourists. On a smaller scale, many habitats can be disturbed both above and below ground by burrowing creatures such as gophers or moles. All of these disturbances can change the composition of species in a habitat and can also change relative species abundances. Both the intensity and the frequency of disturbance can influence how the composition of species in an area will change. In general, when disturbance is minimal or rare, then the species that are best at competing with other species for resources will eventually take over. Alternatively, when disturbance is extensive or frequent, then species that are good colonizers or can recover from disturbances rapidly will be at an advantage and will dominate. For example, a forest that has not been disturbed for a long time generally hosts species of trees and other plants that can grow under low light, but will not include many grasses or bushes. If the same area were burned periodically, the trees would rarely have time to become established. Instead, a grassland community comprising species capable of...

Although this college is meant primarily for Catholics, it admits other students irrespective of caste and creed. The College aims at training young men and women of quality to be leaders in all walks of life, whom we hope will play a vital role in bringing about the desired changes for the betterment of the people of our country, more particularly of the dalits and other poorer and marginalized sections of society. The College trains young men and women to serve their fellowmen in justice, truth and love. Loyola College became autonomous in July 1978. The College, however, continues to be affiliated to the University of Madras and is autonomous, in the sense that it is free to frame its own course of studies and adopt innovative methods of teaching and evaluation. The University degrees will be conferred on the students passing the examinations conducted by the college. In Loyola, we look at education differently...
