Dust Bowl in the Great Plains

ABSTRACT
The nineteen thirties was the time of great tragedy and crisis in America. Together with the recession that hit its economic fields, an ecological and agricultural problem came next as drought brought the Dust Bowl. It was caused by environmental changes and man-made land degradation. The effects of the Dust Bowl added to the recession and downfall of the American economy, but have resulted to the development of technologies that helped agriculture. It was a remarkable moment for the west as it moulded what it is and where it is in the map of the world today.

INTRODUCTION

Many countries rely on agricultural crops for the food security of their citizens and the stability of their economy. Cultivating crops allowed humans to meet their increasing demands for crops and continue to prosper. Without agricultural products, civilizations would have been different or would have failed to exist. People would have relied on gathering crops and end up exhausting every available resource there is. Nevertheless, as societies and their demands for agricultural crops advance, more strain are put into the environment. People have cultivated crops continuously and some have done it without much regards to the environment. There have ...

Natural Hazards: Droughts

Drought is a period recorded with less rainfall for a specific region compared to its past rainfall data, which might affect surface water flow, groundwater reserve, crop production and food availability. Impacts of a dry spell vary based on its duration as well as local people’s demand for food and water (National Drought Mitigation Center [NDMC], 2016). If the proportion of vulnerable population exposed to drought conditions were higher, then the impact of drought would also be high even if it lasted only for a short duration. In spite of being a natural hazard, the risk of its ...

Abstract

A sandstorm is characterized as one that whips up extraordinary loads of sand into the air, forming a dense cloud above the ground in the process. While most of the sand will rise higher than 50 cm, some sand particles can even ascend to the height of 2 meters. According to Wikipedia, the average diameter of the particles carried by such dust storm winds will vary between 0.15 and 0.30 mm. Wind speeds such during sandstorms have been recorded at up to 16 km per hour and more, while most storms continue to blow for between three hours to ...

Introduction

Pollution of the environment is one of the oldest problems in the history of civilization. Man has long been considered the environment primarily as a source of resources, seeking to achieve independence from it, to improve the conditions of its existence. While population and the scale of production was small, and very extensive natural spaces, to achieve the goals we were willing to sacrifice some of the untouched nature, exactly as some degree of purity and water. This process in our relatively closed, not unlimited world cannot continue indefinitely. For example, it is estimated that each year for every person ...

The decrease in world’s petroleum and oil supply has led the nations to look for alternate sources of energy. As a result of this short-supply, unconventional gas reserves are gaining importance as alternative source of crude oil, where the unconventional gas reserves are estimated to contribute to 45% of the US gas production by the year 2035. Large-scale extraction of unconventional natural gas has resulted in the development of new and untested extraction technology such as hydraulic fracturing or hydrofracking, which is expected to develop rapidly in the next few decades near human settlements and pose a health hazard (Adgate, ...

Asthma is a complex multifactorial disease that affects millions of people worldwide and can occur across any age or ethnicity. In children, boys are slightly more affected than girls, but in adults, women are more affected than men (Fanta 1002). Asthma affects about 300 million people and accounts for around 250,000 deaths each year worldwide (Lv et al. 105; Ober and Yao 11). Asthma can be atopic or non-atopic. Atopic asthma usually starts in childhood or adolescence and is hypothesized to be influenced by genetic predisposition. Non-atopic asthma usually occurs in adults and can result from bacterial or viral ...

Introduction

Architecture is very significant in people’s life. Hence, every building should be created correctly. The point is that people face buildings every day: we lie in houses created by architectures; we work in offices created by them as well; we shop in malls projected by architectures. However, some architectures do not strive to build correctly. Although, there is no clear cause for it, but there are many cases when “badly built” buildings cause different diseases. Doctors call it sick building syndrome. This research is devoted to the issue of sick buildings and the syndrome they cause. The peculiarity ...

How PPE’s make the Workplace Safer

As the objective of a Personal Protective Equipment program is to stop occupational injury from taking place, it cannot be the first option for protecting workers. The employment of PPE does not stop disasters from taking place. PPEs merely reduce the exposure or severity of the work place related injuries (Spellman and Whitling, 335).

The parts of the Body that are protected

Hygiene or comfort masks protect the workers from excessive dust. Ear muffs and semi inserts will protect the ears of workers in places where there is a great deal of noise (Spellman and Bieber, 119). This kind is best worn by workers who are frequently exposed to ...

Allergies vary from one individual to another and a substance causing allergic reactions to one person may not cause the allergy to another person. These allergens could be ...

EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

Background: Clinical Description

The disease causing agent, Coccioides spp., causes a wide range of illness, but these illness are mostly determined by the hosts' defenses, inoculum size and possibly specific organism virulence. Most of the clinical infections (about 60%) show few or no respiratory symptoms. However, the rest 40% may show symptoms of illness that may either be acute or sub-acute. The illness could range from progressive pneumonia to flu-like conditions. Misdiagnosis usually occurs in self-limited community-acquired pneumonia. According to Saubolle, McKeller & Sussland (2007), only 29% of 56 people who had community-acquired pneumonia were diagnosed of coccidioidomycosis.

A Problem Exists

Riding motorcycles without a helmet can be equated to confronting a risk head on while hoping that chances will likely save you. The best way to stay safe is by preventing the risk in the first place rather than trying to find ways of reducing the impact of the risk. The numbers of motorcycle accidents over the recent past are evidence as to why all motorcycle riders should wear their helmets at all times when riding their motorcycles. Several studies have been conducted by different companies trying to look into the issue of whether the helmets have any correlation ...

Introduction

Antigone is a dreadful tragedy written around 441 BC by the Sophocles. It was the last of the Theban plays but chronologically written first. The other pieces of Sophocles have attracted more controversy and nothing has inspired people more than Antigone (Lewis, p. 35). It is an outline of achievements of man, modern in its tone deceptively, has impressed many, and most probably, it is said if it is attached with, choral odes would turn to this poem. It was written at a time of a national intensity or fervor. When the play was performed, Sophocles was known to ...

The Effects of Climate Change on Allergies and Asthma Cases

Since the discovery of global warming or climate change, scientists have been warning the public of the possible implications this phenomenon could bring. They highlight erratic and severe weather patterns, changing ecosystems and the persistence of diseases that cannot easily be treated. While skeptics remain ignorant over these warnings and governments trying to make amends over their national policies, statistics show that these warnings should be taken seriously especially with regards to respiratory diseases such as asthma and allergies. However, it is a question as to what impacts climate change has towards the prevalence on allergies and asthma cases ...

Initially, many people thought that the growth of the economy and industry is the crucial matter in the market. The perception has changed because most people now believe that the environment is the main imperative issue that people should put into consideration. Within diverse centuries, the consideration of people on the environmental subject or development problem has always changed (Peet 23). Is it because the environment problem affects the development issue or the development influence the environment problem?
The establishment of the accurate notion of development and the connected development sculpt is central in economical creation. In the past ...

Abstract

The seawater forms 97% of water of the world, and the icecaps account for 2%. The portion of water available for human consumption is barely 0.5% and that also in aquifers. The widening gap between availability and requirement of potable water especially in the Gulf countries has necessitated newer methods and technologies for production of water suitable for human consumption. This situation in the Gulf region has developed due to non- availability of surface water, high growth of population and urbanization, and water depletion. The present paper takes account of the desalinization of seawater plant established in Abu Dhabi ...

The origins of the Sphinx was derived from Egyptian, Persian and Greek Mythologies. A sphinx is a mythical beast with a body of a lion and a human head. In Greek mythology, it is portrayed as a winged beast who preys upon humans who cannot answer its riddles (Pinch, 206). Early Persians also believed that the Sphinx was a guardian deity whose mission was to protect the royal Persian Gods (British Museum, n.p.). Meanwhile, the Egyptians also built a sphinx of their own. The Great Sphinx located in Giza, Egypt had been buried in the sands for hundreds of years not until the early 19th century ...

Incinerating means burning waste or trash until what is left is ashes awaiting disposal. An incinerator is a machine used to burn waste and trash until these materials are reduced into ash. The device is constructed using heavy machinery and well insulated materials that protect heat transmission into the immediate environment. Incinerating serves to keep hazardous material from finding their way into landfills where they can harm workers in such facilities (Donohoe 2003, pp. 588). The devices produce power while in process of waste burning that can be used elsewhere. The byproducts of incineration are air and smog pollution, and ...

The hell debate

Introduction
The debate about hell and its nature has been passed on through generations since the 5th Century. Concepts and ideas have advanced a great extent through the 2,000 year Christian history. Theologians and various denominations fail to agree on matters such as qualifications of the humans ending up in hell and its nature. While some base their argument on early Christian believes, others offer first-hand experience claiming they visited hell and were able to return to earth and tell their tales. Some disagreeing parties accuse others of modifying the doctrine of hell making it less horrifying and ...

Description of Disease

Chronic obstructive pulmonary disease or COPD is a progressive illness due to which the sufferer is not able to breathe easily. In this connection, progressive means that this disease worsens with the passage of time. In COPD, the patient’s coughing produces mucus in large amounts, puffiness, breath shortness, tightness of chest, and similar other symptoms (Currie, 2011).
There are two major conditions in COPD i.e. chronic bronchitis and emphysema. Emphysema refers to the condition whereby damage of the walls between several air sacs occurs. Consequently, the air sacs become flaccid due to the shape loss. Such damage also ...

Introduction

An estimate of 861 billion tons of coal deposits exist worldwide. According to the present rate of production, this amount can last for 112 yrs contrary to the oil and gas reserves that will last for fewer years approximately 45 to 54. Several countries in the world have coal reserves found in the biggest ones are China, Russia, USA and India. To prove recoverable reserves, engineers drill on the ground hence technically and economically extractable.
In contemporary times, reaching peak coal is questionable due to fall in the ratio of reserves to production. The point when there is ...

Introduction

For more than 150 million years, dinosaurs roamed across the earth. However, most dinosaurs became extinct suddenly within a short time. The last of the dinosaurs are estimated to have died about 65 million years ago. The cause of their extinction continues to be a mystery, with a number of factors such as diseases, climate change, geologic events and changing plant communities being thought to have played a part in the demise of dinosaurs. Of late, theories of dinosaur extinction have been the subject of much controversy and debate. The explanation that seems to have the support of many scientists spells out that ...

Comparing Asthma to Emphysema

Asthma refers to a disease, which causes lung airways to narrow and swell resulting to breathe shortening, wheezing, coughing, and chest tightness. On the other hand, emphysema refers to a kind of chronic obstructive pulmonary disease or COPD and involves damaging of the air sacs or alveoli that are located in the lungs. This causes oxygen shortage in the body. Emphysema also damages the elastic fibers holding open the minute airways going to the air sacs, and this causes these airways to collapse when breathing out preventing the air in the lungs from escaping (Mayo Clinic, 2011).
The main cause ...

Foundation of modern cosmology

Cosmology being the study of the universe has been changing over the years to what we currently view it as. Modern cosmology has been founded on the works of various principals who have studied astrology over time and during different eras.
The ancient European medieval and ancient Greeks believed the earth to be the at the universe’s center. They believed that the moon, planets, and sun were orbiting the earth. This idea was believed by many including the Catholic Church who in fact influenced people of their religion to believe so. The Catholic Church banned anybody from ...
