the ecosystem and the human system. In 1930 a British botanist “coined the term ecosystem” in order “to define the complex interrelationships between plants, animals, and microorganisms and the physical elements they interact with—rocks, soil, water, air” (Fraser, 113). This idea of an interdependent ecosystem caused scientists to rethink previous attempts at preservation. As Fraser notes, “To seal off is to interrupt processes that make life possible: natural selection, predation, competition… Wrenched

sustainability worksheets used to complete the evaluation aided the team in locating common areas of non-sustainable practices relating to land, water, and air pollution. The three non-sustainable practices evaluated further are solid waste, and hazardous waste causing land pollution, hazardous waste causing water pollution, and gaseous waste causing air pollution. These areas are the most harmful to the immediate population, which includes the plant workers and the communities. Solid Waste and Hazardous

Chapter 1 INTRODUCTION The project ‘Heat Transfer Studies on a 7.5 Watt LED Lighting Load using Finite Element Analysis’ is mainly 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

interact with and receive information from the environment, sight being the most useful. Trying to figure out what something far away is, in a star’s case, far enough away to make a giant ball of burning helium look like a speck, is something that requires a tool. Telescopes were the first tool that really helped humans see into the heavens, letting them study the stars and the ‘wanderers’ which eventually were found out to be planets moving around the sun (although at the time they were discovered, it

history. This may or may not be the case (Huffington Post, 2009). Findings in the area of determining the age of some written languages are uncertain. But for the most part, Sumerian is a definite running mate for the title of oldest written language. Sumerian was first started to be put into writing around 3200 BCE (Academia.edu, 2007). The main reason for the start of this was for agricultural purposes. Clay counters were used to keep track of how many plants were sealed into a container. Those counters

The purpose of a site investigation is to identify the ground conditions which might affect the proposed development. It enables better understanding of the site and immediate surroundings, which will enable safe and economic developments. They are a common requirement of the investors as well as the regulatory authorities. In the broadest sense, the ground conditions are understood to include not only the underlying soils and rocks but also the groundwater regime, any contamination and effects

persist long after other skeletal structures have succumbed to organic decay or destruction by some other agencies, such as fire [3] [4]. Rugoscopy (study of palatal rugae patterns), cheiloscopy (study of lip prints), tooth prints, radiographs, photographic study and molecular methods like Polymerase chain reaction (PCR) are various methods used in the study of forensic odontology.

It is defined as mucosal erosions equal to or greater than 0.5 cm. As many as 70–90% of such ulcers are associated with Helicobacter pylori, a spiral-shaped bacterium that lives in the acidic environment of the stomach; however, only 40% of those cases go to a doctor. Ulcers can also be caused or worsened by drugs such as aspirin, ibuprofen, and other NSAIDs.[2] Four times as many peptic ulcers arise in the duodenum—the first part of the small intestine, just after the stomach—as in the stomach itself

the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large
