Abstract

Radiation cataractogenesis (RCG) is deterministic. It does not occur below a minimum threshold dose. RCG is generally believed as dose-related. Sliney (1986) believed that its severity is also dose-related. The severity increased and the latency decreased as radiation dose increased above that threshold. The lens of the eye is nonvascular and is known to experience no cell loss over its lifetime, indicating that any damage to its cells will not result to the removal of these cells for lack of existing mechanism. Three induction mechanisms were explored (direct, indirect, and oxidative, which separately creates oxidative stress inside the lens Continue reading...

Mining refers to the extraction of valuable mineral resources from the earth’s crust. While some minerals are found at the earth’s surface, other minerals are found deeply below the earth’s surface. Irrespective of their location in the crust, the extraction of minerals is a complex process often fraught with danger. America’s mining industry has been supported by the increased demand for raw materials by other sectors of the economy. As the demand for mineral resources has increased, mining has become more complicated leading to accidents. Mine disasters refer to accidents that occur during mining activities Continue reading...

It is very obvious that we all study, read and write a lot in the classes. Till our academic life, all we do is learn in the classroom. However, in the professional life, we don’t have to sit in the classroom and learn. This does not mean that the process of learning is over. The process of learning is not destination or a mile stone to achieve in life, it is a continuous process. Even after Continue reading...

Natural disasters such as earthquakes, typhoons, and fires are akin to man-made disasters like food, which are contaminated with hazardous materials that will put people’s lives at risk. Risk, as defined in a Federal Emergency Management Agency or FEMA mitigation report (1997), is “the potential losses associated with a hazard defined in terms of expected probability, frequency, exposure and consequences” (p. xxv). Both these disasters bring detrimental results to people who experience it and who are about to experience these cataclysms.
FEMA (1997) provided five major elements for the strategy they are going to use for atmospheric hazards Continue reading...

INTRODUCTION

There is a screeching sound, bright lights, everything is spinning, you feel pain and then silence. This is the description of a car accident; an event that occurs hundreds, if not thousands of times per day all over the world. People are critically injured, bleeding profusely, and life is ebbing away. The first responders, EMS and paramedics, know that these patients are in need of transfusions to restore the blood they have lost. However, the hospital is several miles and many minutes away and the victims may not survive the transport. In the face of accidents, natural, disasters, and Continue reading...

The Pacific Northwest is the most volcanically active regions in the United States. It consists of several volcanic peaks which stretch all the way from Canada to northern California. Falling in this region is the southwester territory of Washington State, which has witnessed some of the most spectacular volcanic activities in recent times. Mount St. Helens, which erupted in 1980, is located in this region (Harris, 2005). The volcanic eruptions in this region result from plate tectonic movements.
The plate tectonic theory is based on the postulation that the Earth’s outer layer, lithosphere, is composed of several plates. Continue reading...

Abstract

Three tests were made on the kerosene sample: (a) determining hydrogen content by Nuclear Magnetic Resonance [NMR], (b) determination of viscosity by U-tube viscometer, and (c) flash point determination by Pensky-Marten closed-cup tester. Results suggest that the kerosene sample has 13.73% hydrogen content, 7.706 mm2/s kinematic viscosity at -20°C (extrapolated using Sutherland Viscosity Law), and 52-53°C flash point. These parameters characterized the kerosene sample as aviation fuel in terms of heating value, degree of saturation, pressure drop in fuel lines, pumping characteristics and safe handling. All parameters passed the standards derived from aviation literature. These parameters could Continue reading...

Aswan Dam is located on the river Nile in Egypt. It was built and completed in the year 1970. The construction cost of the dam was one billion dollars, in total. Its reservoir capacity is 5.97 trillion cubic feet. The primary purpose of this dam is to control floods, create hydroelectric power and be a source of irrigation (Guertin). It is built upon Lake Nasser and is made up mostly of rock and clay. Planned by a team of British engineers and built by a team of Soviet Engineers, Aswan Dam is one of its kind. Aswan Dam is Continue reading...

Summary
The experiment is meant to study the carbon dioxide absorption process in a packed tower mechanism column. The pressure performance of a packed column was determined experimentally. The calculations shoed that the pressure difference between the top and bottom part of the column is directly proportional to air flow rate; as the water flow rate increases, the pressure difference increases as well. However, at high water and air flow rates, the column flooding appears. The rate of carbon dioxide absorption was calculated. It was determined, that absorption increased carbon dioxide concentration by 80%.

Introduction

Gas absorption is an industrial Continue reading...

Working in an environment with little safety standards can be risky for workers. The safety manager for Podunk University in Colorado left work one and a half years ago. After completing college, I became the new safety manager at the University with strategies for safety. As a new Safety manager, I would have to work on hazardous materials and waste issues to make the institution safer for workers and students.
