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.

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...

INTRODUCTION

Baghouse filters are fabric filter units consisting of one or more isolated sections containing an array of fabric bags (Vatavuk, 1998). Shapes of these bags range from round, flat, tube-shaped, to pleated cartridges. In theory, gas containing high particulate matter level passes through the fabric bag surface. The particulate matter is retained while the cleaned gas is either recycled to the process or vented off the exhaust. This paper attempts to discuss the different concepts behind baghouse filters in relation to environmental engineering. Specifically, this paper discusses (a) particle pollution, (b) baghouse filter principle, (c) filter media selection, (d) types of ...

Stars begin their lives from molecular clouds or nebula of gases and dust. These gases and dusts exert forces to each other that make them want to move farther away from each other while at the same time there is gravity that attracts them together into a small space within the nebula. The chemistry which starts the star’s life begins when gravity starts winning in the war between the two aforementioned opposing forces. As gravity pulls the dust and clouds together it begins to accumulate mass and a swirling motion typical to a spinning disc. At its center are dusts (NH3, ...

Introduction

Aeolian processes occur in environments such as deserts, agricultural fields, and coastal regions. The features of such environments include a nonexistent or sparse vegetation cover, strong winds, and a supply of fine sediments. In Egypt, the increase in human population has led to the lateral spread of human settlements from the Nile’s flood plains to various locations in the western desert land. Such areas include the Kharga Oasis, where the government has initiated land reclamation projects for agriculture and human settlements. However, the developmental plans have missed the issue of natural hazards such as dune movements. Hence, the success of such ...

Abstract

In “The Death of the Author,” structuralist thinker Roland Barthes suggested the notion of the author as a distinct identity in the creation and interpretation of a text was a thing of the past. Instead, he preferred the use of the word “scriptor” to refer to the person writing or typing a work for the first time. The ideas in the scriptor's mind would have to travel through his or her semiotic filters to make it to the paper – those filters take the ideas and shape them – for ...

When World War I broke, earlier poets wrote poems celebrating the outbreak of the First World War. These poems reflected an over-optimistic, sentimental and unrealistic attitude to war that mirrored the attitude of the British people, who assumed that the war was chivalrous and heroic. Rupert Brooke's “The Soldier” is an example of such early World War I poetry, in which Brooke uses strong figurative language and symbols to romanticize and sentimentalize the horrors of war. By 1915, both the British people and poets began to realize how horrific and terrible the war really was, and poems thereafter ...

The variability of stars existing within our universe represents diversity and uniqueness. Humanity may not observe the whole life of a single star, however, techniques have been proposed to study the stars. We have different ways how to measure a star's temperature, age, and mass even, even though it seems impossible. The said variability of stars is key to the measurement of a star's characteristics. The existence of variable stars suggests that stars change on a time interval, unfortunately, too long humanity cannot observe. Nevertheless, humanity have developed a way of understanding the stars through their variability. Needless to say, variability provides unique ...

Since the earliest times, man pondered about existence, where he came from and the purpose of life. Before science came to be, humans looked towards God and the sacred books to find the answers to the greatest questions. The most ancient of these books are the Bible, Torah and Quran. In the Book of Genesis in the Bible we learn that God created the world in six days, and on the seventh he rested. Genesis also says that every living thing was created by God. For a long time science and theology were seen as rivals, however there were several ...

[Interpretive Question: Why does Adrienne Rich enjoy her moments with her lover when she seems to be against the practice of cohabitation?] Adrienne Rich’s poem, “Living in Sin”, explores her viewpoints regarding cohabitation, or the mutual decision between lovers to share a single house even if they are not yet married. This poem is not only romance-based, but also suggests implications on the problems concerning cohabitation and having sex outside of marriage, more particularly from the side of a female lover.

For too long, we have tried to ignore a sneaking suspicion that as a race of people we cannot continue to use our planet’s resources in the way that we are accustomed. It has been said that we are “long on things but short on time” (see Durning 179, for example). In this essay I will look at why that is: how stress is being placed upon our water resources and upon our biosphere as a whole, and how this is generating conflict between people, governments and personal values; in addition I will consider specifically what, if any, responsibilities should be ...

Recently, dust inclusions found on the meteorite from 1969 have been reexamined. This led to a new discovery. These dust inclusions turned out to contain stardust grains which originated from a supernova. The interesting part is that they originate from a supernova older than our Milky Way solar system. These molecules are vital and play an important role in the emergence of life. The team had originally isolated some silicon carbide stardust grains and using a sensitive spectrometer analyzed them. What they found was beyond their expectations. It turned out that these samples had an unusual isotopic distribution, which does not fit with ...
