Describe air quality conditions in the US before steep regulations were imposed.

The United States has experienced the worst air quality conditions during the 1940s and 1950s as an effect of the progressing industrialization and urbanization. Another main reason is that the United States has no national regulation and policy towards hazardous gas emission and air pollution during these periods of time. During the 1940s and 1950s, the United States have experienced deadly photochemical smog on major cities including Los Angeles and Donora(Williams, 2013). In addition, the ozone levels in the lower layers of the atmosphere exceed its limit and become dangerous to people as well as the environment. During ...

Weather is referred as atmospheric conditions that may be warm or cold, clear or cloudy, wet or dry, and calm or stormy. These weather conditions occur in the lowest part of the earth’s atmosphere called troposphere. It is variations in day to day temperature that characterize weather and its conditions. In this essay, we strive to know weather, its causes and effects, and weather forecasting and weather modification efforts.
When the term weather is referred; it is earth's weather and it differs from climate that refers to average weather conditions which sustain for a longer period. Causes of ...

1.0 Introduction
Many sports played across the world that involves throwing, hitting and kicking are done so using a ball. However, many parameters such as humidity, materials of manufacture of the ball, size of the ball, etc. control the movement of the ball in air. Research on golf balls and tennis balls reveal their aerodynamic properties and the various parameters affecting their flight. The effect of seams on a baseball on the flight has been evaluated along with the relationship between rotation and lateral forces (Watts & Sawyer 1987). Similar studies have also been conducted on cricket balls, rugby balls, volleyballs ...

First of all, it is important to note that the winds emanate from storms. Bearing this is in mind, it is worthwhile to understand what is a storm is. The earth which we live in is covered by air. Air like any other forms of matter has weight and at the same time occupies space, which means that it has volume. The air covering the earth is not static, but keeps on moving based on environmental factors such as temperatures, earth’s rotation, and the revolution of the earth’s orbit around the sun which creates the various seasons that ...

Basic Modules of Gas Turbine High Bypass Engine

Air Inlet Section: As shown in figure 5, the air inlet section is the most forward section of the engine. This section forms the air inlet for the engine and houses the inlet guide vanes. The purpose of the vanes is to direct the incoming air at the proper angle to the first fan stage. The vane at the bottom of the air inlet is thicker than the others in order to accommodate engine tubing. As indicated in figure 6, the no. 1 bearing support assembly is mounted in the center of the compressor inlet case. Behind the front ...

Discussion

It is true that the patient might be suffering from Swimmer’s ear. According to Hui (2013), Swimmer’s ear is commonly experienced in children and adults. It is clear that swimmer’s ear also causes inflammation, fullness in the inner ear and possible hearing loss (Hui, 2013).It is also true that most of the diagnosis is done by the observation of the outer ear such as the pinna. In some cases, the inflammation of the outer ear might be caused by complications in the fluids found in the inner ear. An otoscope could, therefore, be used to ...

Abstract

Weather plays a significant role in shaping of the earth. The weathering process leads to breaking down of soils. Water cycle is one of the integral parts in the earth ecosystems that maintain a balance of atmosphere and climate of the earth. The experiment performed proved the phenomena of energy balance and helped to understand the water cycle, weather, climate and atmosphere

Fluid Mechanics is a branch of engineering study and it deals with various properties of fluids. In our daily life we use various types of fluids. Most of the fluids are readily available and have some excellent properties. Significance of Fluid mechanics is to know how the fluids and its various properties can be used in our daily life. This part of engineering is integral part of main stream engineering like Civil Engineering, Mechanical Engineering as well as Chemical Engineering as these brunches of engineering often deals with fluid. In this essay various aspects of fluid mechanics and its application ...

Electricity and magnetism will propel the future transportation system, and it will make our travel safe, smooth, but faster than other conventional transport system. The new transportation technology is magnetic levitation or Maglev, and in this transportation technology, the train remains suspended and move in the air freely without any support but, under a strong electromagnetic field. The speed of maglev vehicles can be between 300 to 500 kmph. The technology is based on the familiar property of magnets that the opposite poles attract and same poles repel. For example, the north pole of a magnet will attract the South Pole of ...

Introduction

A boomerang is a curved wood that when thrown comes back to the thrower as a result of asymmetrical lift; one of the underlying principles in aerodynamics. As Mason notes, there are several types of boomerangs; the curved boomerang, the cross stick boomerang, the boomabird, and the tumblestick (7)- all differing in length and the material used in making them and perhaps the purpose. Of the four types of boomerangs mentioned above, the curved boomerang is the most prevalent, and for this reason, it is the one is referred to in this paper. The boomerang was particularly popular with the ...
