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 ...

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 ...

Fire systems are designed for different services such as to warn people of fires, to stop fires, to create a safe environment for people in a fire among other reasons. The installation of these system depends on the buildings and occupants or the kind of materials in the buildings such as flammable liquids or electronic devices. The selection of these systems should meet the set standards by the different fire-related organisations. The following is a look at some of the fire and prevention systems.

What is a Rain Screen?

The rain screen is an exterior defensive coating that sits away from a structure’s outside wall's weather contrary barrier, creating an air crater directly behind the covering that helps to protect the buildings important weather contrary barrier, by providing a moisture management instrument allowing air intrusive through to vaporize any lingering moisture between the structure’s walls.

It is an attempt to understand the architectural and design structure concerning the background check and application of vital principles used in back ventilation and pressure equalized rain screen principles. These systems provide drainable compartmentalization to limit water penetrating during heavy rains ...

Our respiratory system is composed of the air passages provided by 1) nose, 2) pharynx, 3) larynx and 4) the respiratory surfaces of the lungs. The primary function of this system is ventilation and gas exchange. However, there are certain secondary roles played by this system viz. olfaction, phonation, and stabilization of the thorax during the mechanical exertion and certain other biochemical functions. Anatomy and physiology of the larynx: Larynx (commonly known as Voice Box) is a part of lower respiratory tract and is the organ for phonation (generation of sounds). Basically, Larynx is an air passage and has a ...

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 ...

Introduction For the past couple of decades since the onset of the Industrial Revolution, scientists have slowly began a campaign to raise awareness to the changing state of the planet. Records of high temperature changes, onset of diseases and erratic weather patterns have been reported worldwide, each change becoming more severe as the years progress. When it comes to erratic weather patterns, scientists highlight the now common occurrences of natural disasters such as hurricanes or cyclones. Although skeptics stress that ...

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 ...

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 ...

Introduction

Heat of vaporization and vapor pressure are the two essential properties of a liquid in thermodynamics. The vapor pressure of a substance is the measure of the tendency of its molecules escaping (Blauch). The heat of vaporization is defined as the amount of the attractive energy that exists between molecules in the liquid and has to be overcome in order for the molecules enter the vapor phase. When a liquid sample is put into a container, there is the tendency for the liquid to evaporate. Liquid molecules escape from their state into the gaseous state. When the liquid is put in a closed container, ...

There have been climatic changes over the years that have led to the development of research in the meteorological department. Certain climatic changes have led to the occurrence of one event or the other. All the parts of the world face climatic changes in one way or the other. However, some parts of the world become more affected than others due to differences in landscape and the overall environment (Miller 2007). In Australia, one of the reasons why there have been variations in climate is due to the existence of the Southern Oscillation. In some instances, the southern oscillation ...

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 ...
