Introduction As we know, the “Critical Zone” is the zone that extends from the vegetation outer limits to the lower limits of groundwater. This zone is important for all life on the Earth. It provides most of the ecosystem services on which societies depend. In this case, erosion processes are dangerous enough for the Critical Zone and they must be timely identified.

Discussion

The erosion is a quite dangerous geological process, as it leads to rather unfortunate consequences (for example, structural failure, displacement, shrinkage of the foundation, and some others). This process leads to the destruction of the rocks (soils) ...

“The Worst Hard Time” is a book that tells the story of inhabitants who stayed in the plains during and after the dust bowl. The dust bowl was a period characterized by animal losses and crop failure in several areas (Egan 54). This created a hostile environment for any person to survive although some people decided to persevere. The book takes a keen interest in the people who stayed through and after the tough times by establishing their reason for holding on. It does this through a collection of their experiences and relating them to the terrible events of ...

The term ‘worldview’ simply refers to an individual’s perception of the world around him, which is often based on the existing knowledge that he has accumulated over the years. As observed by scholars, people do not possess a ‘tabula rasa’ or blank mind when it comes to the natural world around them since they have their own opinion and values as shaped by their “socio-cultural environment or from previous educational experiences”.

The question of origin – (How did life begin? How did mankind come into existence?)

According to the Christian beliefs, all life forms, including mankind, were created by God. This belief is clearly articulated in the story of creation in ...

1. How can the disease described above create a mismatch between ventilation and perfusion? Use your understanding of alveolar dead space and physiologic shunt to explain your answer. In coal-miner’s pneumoconiosis, respirable coal dust that are inhaled for long periods of time trigger hyperactive immune responses that lead to destruction of the lung. At the beginning, coal dust particles are expelled out of the lung through the function of pulmonary macrophages beneath the epithelial layer of airways and near capillaries (Kopf, Schneider & Nobs, 2015). These macrophages phagocytize the dust particles and transport them to the lymphatic tree or ...

Introduction

The term “ecological problems” is nowadays used to define a number of environmental problems. Given the modern environmental mess and the truth that the world has many environmental problems than before, it is no surprise that a lot of emphasis is actually put at this negative ecological context. This is the reason why no difference exists between ecological and environmental problems in everyday talk. Environmental problems are also ecological problems since environment is essentially a center of all the ecological research. All sorts of pollution, climate change, endangered animals, deforestation, are all problems of ecology since ecology uses the scientific approach ...

Is baby Steven gaining too much weight too quickly? Based on growth patterns and recommended weight gains for infants under one year, baby Steven is gaining weight on a perfectly normal scale. Based on reports by the CDC the average weight a baby is supposed to add in the first month is between 4-7 ounces or 112 grams to 200 grams. During breast feeding, infants who are breastfed grow differently from those gaining their nourishment from supplements and formula (Johnson, 2012). The average weight gain for a breastfeeding baby is between 0.5 kg to 1 kilogram every month if growth. The height ...

Question 1

Jupiter was the first giant planet formed.

Question 2

According to the Nice theory where did the Kuiper belt objects and Oort cloud objects come from?

Kuiper belt objects come from the out edge of Solar System where huge spheres made of rock and ice that circle around Pluto’s orbit. The objects took their name from Gerard Kuiper who suggested that comets may come from the Kuiper belt. This group of planetoids is called Kuiper belt objects (KBO). The first KBO named “1991 QB1” was discovered in 1992. The plant Pluto also belongs to the group of KBO. Some ...

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 ...

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 ...

Chemical and Biological Agents and Radiation

Hydrogen cyanide (HCN): HCN is a highly toxic chemical blood agent in the form of a colorless gas. Cardiovascular, neurological, respiratory and thyroid effects can occur as a result of chronic low exposure to HCN (Blanc, Hogan, Hryhorczuk, Hessl & Bernard, 1985). In case of exposure to liquid HCL, mild soapy water can be used for decontamination. Either sodium or amyl nitrite combined with sodium thiosulfate can be can be used as an antidote for the effects of HCN poisoning (USAMRICD, 2000). Treating patients with poor oxygen-carrying capacity can be a bit challenging because nitrite-induced methemoglobinemia can be harmful. (Chandra, Gupta, Bhargava, ...

The Oklahoma City bombing occurred at nine o’clock during the day in April 1995. It saw the bombing of the Alfred P. Murrah Building. Two critical safety steps that were essential in the management of the disaster entailed the establishment of a safety perimeter that would limit the extent to which the first respondents could reach and the immediate withdrawal of the trapped bodies from the danger zones. The former essentially contributes in accountability and management of the respondents. It should be noted that the respondents’ desire to save anybody in the disaster must never escalate to levels that ...

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 ...

So, how much the humanity knows about the fiery star that can kill the entire earth in one second? Since the beginning of time, people looked at the sky, hoping to learn a little about the twinkling stars and the fiery sun. As we ...

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 ...

Several human activities influence the earth unfavorably. A stone crusher includes a great deal of suspended particulate matter and clamor into the air. Vehicles radiate from their tail funnels oxides of nitrogen, carbon dioxide, sulfur dioxide, carbon monoxide and a complex combination of burnt hydrocarbons and dark residue which pollute the environment. Local sewage and run off from farming fields, weighed down with fertilizers and pesticides contaminate water bodies. Effluents from tanneries contain numerous unsafe chemicals that transmit foul smell. These are just a couple of cases which demonstrate how human activities cause environmental pollution. Pollution may be characterized as expansion of ...

Asthma is a respiratory disorder that affects the respiratory airways. It is characterized by inflammation and subsequent narrowing of the air passages. It leads to episodes of wheezing, coughing, dyspnea and chest tightness. It mostly occurs in the night or in the early morning hours. It may affect people of any age, but commoner in young children. In the United States, there are approximately 25 million asthma patients, out of these, 7 million are children (National Heart, Lung, and Blood Institute, 2015). In this paper we will discuss about a 15 years old boy who is diagnosed with asthma. We ...

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. These conflicts involve the poet’s belief on society’s discrimination against cohabitation, her own sense of moral ...

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 ...

Abstract This paper examines the air pollution problem in Ulaanbaatar, Mongolia. Heavy pollution in the city has become a concern because of the increasing cases of health problems. Many babies are being born with defects in vital organs, pregnant women are miscarrying and the level of respiratory disease cases has risen. Although burning of coal in homes, during winter, causes pollution other sources of pollution contribute as well. The high altitude and the mountains surrounding Ulaanbaatar worsen pollution in the city. In winter, the Siberian anticyclone causes the city to have temperature inversion and high pressure, which do not ...

Exercise 1: Anatomy of the Respiratory System

What are the two functions of the larynx? Larynx is a cartilaginous and a muscular structure while holds vocal cords together. It is used by human beings to talk, swallow and breathe. It is lined by the mucous membrane hence forming part of the respiratory system. Larynx protects the airways by closing quickly after mechanical simulation hence stopping respiratory and curbing the entry of foreign substances into the airways. The larynx also produces sound, controls ventilation and acts as a sensory organ.

Indoor Air Pollution: Diagnosing the Causatives and Effects

Indoor air pollution is the presence of physical, chemical and biological contaminants in the indoor air that are never present in the quality and environmental friendly atmosphere. These contaminants can be particulates, gases, moulds or radon which is the main causes of the pollution. The human immune system protects the entire body against the negative effects of these contaminants. The contaminants impair the immune system after prolonged exposure. A survey published on the metropolitan area of Toronto revealed that almost 2 percents of the annual deaths were caused by indoor air pollution (Tom, 1996). In this essay, we have ...

If we are going to search for the final answer of life, it means that we are searching for the purpose of our existence, for the meaning of life. The inquiry regarding the purpose of the life on Earth has been a central topic in our history. It is considered to be an insightful metaphysical inquiry. It is a problem that can affect everyone in upon inquiry in whichever aspect. Answers about the meaning of life can be ‘happiness’, ‘love’ or ‘to live truthfully’. However, if we are going to answer the question metaphysically, we should involve some philosophical principles. ...

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, ...

Religion and science are more connected than people in general actually think they are. In the Middle Eve Galileo Galilei was accused to be a heretic because of his assertion that the earth is not the center of the universe, as it moves around the orbit of the sun (Eppur, si mueve) (Galilei in Gibbons 109), later on his heresy was proved scientifically correct. The eternal being that Clarke’s Cosmological Argument is founded on has also been explained scientifically as the Big Bang theory, the beginning of everything. From that primordial explosion star dust spread and it continues to ...

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 ...
