Essays on Debris

Abstract

Space junk is a real problem today, what with million useless pieces of junk orbiting our planet. We do not see that junk does not mean it is not there or cannot be a problem. The technology we use today is innately tied to space as our modern life relies on functioning satellites. The paper looks into the presence of space junk and the issues related.

Introduction

Space junk is the collection of all the debris orbiting the earth. This orbital debris has been classified into two forms – natural and man-made. The natural debris consists mainly of fragments of meteoroids ...

Introduction

The Kessler Syndrome is defined to be orbital debris tenure that has developed into accepted outer the specialized orbital debris area without ever getting a severe explanation. The goal of this study is to explain importance of Kessler syndrome and its impact on the organizations to change its climate and to place the inference into the approach after research by the worldwide scientific community, as well as to argue what it might signify to potential space functions.
The term of Kessler Syndrome has derived by Donald J. Kessler. Kessler syndrome preserved the catalogue of synthetic things in orbit, however ...

Introduction
The growing concern of the world to global warming can be traced back to pollution. One of the most apparent is water pollution which affects three-fourths of the whole world. The ocean is where most of the human waste, be it intentional or unconsciously, goes. This waste is called marine debris. It does not only include human waste, but also the natural waste occurring in the environment which escalates as the degradation of the bodies of water continues. According to (U.S. Environmental Protection Agency, 2011), marine debris is any persistent solid material that is dumped into the ...

Guidance on safe entry

It is very easy for rescue workers to drown while trying to access the flooded building. It is quite evident that even professional swimmers can drown in certain circumstances. A thorough study of the architecture of the building should be done (Cauffman and N.I.S.T, 2006). Workers should be enlightened on the topography or terrain that lies therein. They should also walk with copies of the architectural drawing or equivalent documents that will be useful in knowing the layout of the building. Before entry into the building, specific threat areas must be identified (Dasgupta, 2007). For example, workers must be ...

Water, sanitation and Hygiene
These are highly fundamental issues that should be considered when providing community based services. For instance, water is a basic need for human survival but not all the water is safe for consumption. The sanitation systems within the community determine a great deal on the safety of the available water for consumption. Water, sanitation and hygiene complement each other and none can exist independent of the other. The importance of water cannot be overestimated and its use immeasurable. Despite the high demand for the resource for sustenance of life, there is always a greater challenge ...

Mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) is a bark beetle that lays eggs within the vascular system of the mature trees of lodgepole pine (Pinus
contorta). First known epidemic infestation was recorded in 1994 in the forests of British Columbia (BC). Prior to 1994, the infestation was negligible, owing to the fact that extreme low temperatures of winter killed the beetle, thereby curbing the problem. In the past two decades, however, due to global warming the winter temperatures are not low enough to kill the beetle. This has escalated the problem of deforestation and thereby has unbalanced the ...

While on his way to Hiroshima, it was around 7:30 a.m. when Captain William Parsons inserted the detonator along with the explosive charge into the bomb. It was around 8:16 a.m. (Japanese time) when the bomb exploded in Hiroshima over Dr. Shima’s Clinic. The glowing fireball had a temperature of about 50,000 degrees. Soon after this attack, another major city of Japan was attacked. It was basically the idea of General Leslie Groves, General Farrel and Admiral Purnell to launch two atomic bombs on Japan; the first bomb would demonstrate power and the second would tell the ...

Introduction

Marine pollution takes place when potentially harmful or harmful particles, chemicals, waste, or invasive organisms get into the ocean. Most sources of marine pollution are based on the land. Marine pollution usually comes from nonpoint sources dust, windblown debris, and agricultural runoff. Marine pollution can also result from nutrient pollution where excess nutrients is put into the sea. The result of this excess nutrient such as phosphorus and nitrogen stimulate the growth of algae which cause eutrophication on the surface of the sea (Birni & Boyle, 1994). Marine pollution causes presence of toxic particles into the sea. These toxic particles ...

Tissue and Cellular Organization

The circle of life on the earth is very complicated, though sometimes it seems to be rather easy. People see plants, insects, various fluids, surface and soil, but they often do not think of all the complexity of the constitution of bodies that fill up the world. In other words, everything consists of cells and tissues, and in order to understand the essence of every matter it is important to investigate their structure.
There are some organisms, such as bacteria, that are unicellular or they are made up of only a “single cell” (Science Daily, 2014). These one-celled organisms ...

The respiratory system of humans comprises of a complex set of tissues and organs, which gets oxygen from the surrounding and carry it to the lungs. The basic role of the respiratory system is to provide the blood with oxygen so that the blood can convey oxygen to every body part. The respiratory system achieves this through inhalation and exhalation. When one breathes, oxygen is inhaled while carbon dioxide is exhaled. This gaseous exchange is the means of the respiratory system to get oxygen to the blood. The tissues and organs, which constitute the respiratory system of humans, are ...

- Introduction
With water being an essential component necessary to many aspects of domestic life, it also represents an integral component in many industries. Due to water’s inherent solvent properties, water extracted directly form freshwater sources such as lakes, rivers, and aquifers are often times full of absorbed minerals and pollutants unfit for human consumption. Due to this, a variety of methods have been implemented in order to purify water from surface and sub-surface sources. However, the world’s water sources vary greatly in purity to begin with, which results in some methods being much more labor intensive in ...

Abstract

Accidents are an inevitable element of the air carriage industry; however, a good number of these could have been avoided given proper human resource management efforts. The task of these specialists is to recruit, to train, and to evaluate industry employees like pilots. Instead, they often overlook health issues and psychological disorders leaving the wellbeing and lives of passengers exposed to mortal threat. Owing to HR specialists’ miscalculations, pilots with insufficient qualification, those willing to ignore the guidelines of dispatchers and act carelessly received their coveted positions. The liberalization of workplace regulations did the industry an ill favor allowing ...

Fire Investigators Roles

Introduction

Fire investigation is a detailed examination of incidences related to fire. Fire investigators usually begin their work to determine the origin and cause of the incident after fire fighters terminate the fire. A fire incident with injuries and deaths require more detailed information than other fires (IAAI, 2010). The scene of the fire is similar to that of other scenes but it provides a different intensity for the fire investigators. Fire investigators must determine the cause of the fire as well as deal with the injuries and fatalities. The investigators should deal with their emotions in such an ...

Introduction
Despite the call for increased environmental awareness, most people remain unaffected by environmental concerns. Although it is an accepted fact that the environment is everyone’s concern, most individuals and organizations take their social responsibility to nature for granted. Most environmental programs are not taken seriously. For instance, most people knew that throwing litter could adversely affect the environment yet evidence show that this awareness is of no effect or is taken for granted. Cigarette butts, for example, still constitute the largest percentage of street litter, which according to the Environmental Protection Agency (EPA), is the ...

1. Meteors’ Hunting in the Antarctic Glaciers
The Antarctica is a popular and unique area for finding meteors because of the extremely cold weather conditions in this area (Gonzalez). Scientists find meteorites easily in the Antarctica since the meteorites are frozen in glaciers. Moreover, these meteorites are well-preserved unlike those that fall on earth or the sea, where they are hidden among other objects.
Identifying meteorites in glaciers is relatively easy. Since meteorites are dark, they are easily visible against an ice background. Moreover, many of them are preserved for years owing to the freezing temperatures of the glaciers. ...

On whether smoking should be prohibited on university grounds is a long standing issue of debate. For smokers, enjoying their freedom of choice; even if they choose to poison themselves and those around them, must be left on their sole discretion. On the other hand, non-smokers especially those who are very much aware of tobacco smoke’s health and environmental effect, strongly agree to the idea of having a smoke-free campus. It is a common knowledge that smoking does cause cancer and other health problems. In fact, tobacco smoke has been estimated to contain more or less ...

In the discipline of forensics, the field of ballistics is the “study of motion, dynamics, angular movement, and projectile units (bullets, missiles, and bombs). In the context of a criminal investigation, there are a host of possible applications to aid in the facilitation of a criminal conduct. Bullets that are discharged at a crime scene will be inspected in an attempt to discover pieces of evidence and information. Among the pieces of information that police hope to recover from the bullet are the possible type of gun used in the crime, whether the gun was used in a previous ...

Rail construction is a sequence of steps that takes laborious amounts of time in each step and finally results in a wonderful and safe system for transport for many decades to come that requires minimal maintenance over that period. The first step in the construction process is the approval for new line itself. This is typically the responsibility of the government to do it. Once a approval is given for rail connectivity between two points then the role of engineering kicks in.
The first step in the process is the alignment. Alignment is nothing but the path in which ...

The term pollution in the simplest and most basic meaning refers to the condition, situation and circumstance where harmful and toxic materials and substances find their way to the environment thereby making human life inhabitable and unhealthy. In the recent history and empirical evidence has confirmed that human activities have contributed to pollution to the environment and in effect exposing the human race to danger and threats.

Introduction

Natural disasters are bound to happen in any region of the country or continent. Such occurrences mostly result in very catastrophic damages to lives and property. They can derail the economic development of any country as they rob off the necessary resources needed for development (Quarantelli, 1988). Although there is nothing that can be done to prevent these occurrences, a country can do something to reduce the negative impacts of natural disasters. Any country must be ready to prepare for any natural disaster. Resources required before, during and after any natural incident need to be readily available to compact ...

Where does one think all that packages we using everyday are going? It is not a secret at all. It goes to the Ocean. 7 billion pound of plastic are producing in a year. People throwing garbage away to the environment. They are stuck to their ears in garbage, but they still use and produce non recycled stuff.
Some sources claims that trash have been occupy 8% of the Ocean. The largest of the "junk continents" settled in the North Pacific Ocean, in the area between Alaska and Hawaii. Often it called as the ”Great Pacific Garbage Patch”. The ...

Introduction

As a father of free verse, Walt Whitman breaks the limits of the general poetic form, and in general, his poems are prose-like. Even though he did not invent the free verse form, he uses it effectively in his poem that gains fame among the readers. He uses profound imagery in his poems, including debris, rotten leaves, and everything in nature, especially what he considers as nature, which includes sexuality, including prostitution, and death. He reflects and mirrors the nature and the world around him because he strongly believes there is a symbiotic relationship between poet and world. He ...

Sorting of the Receptor

Response to questions
Q. A Describe the main pathway turned ‘on’ by the EGFR to regulate cell growth
MAPK/ERK pathway is the main pathway, which is turned on by EGFR in order to regulate cell growth. This path comprises of a chain of proteins within the cell, which communicates a signal from the cell receptor surface to the DNA within the cell nucleus. When a molecule binds to the receptor at the cell surface, a signal is induced and ends when the DNA expresses a protein, which in turn produces some changes within the cell. One of the common ...

Volcanic Disasters in Modern and Ancient Times: A Comparison

This essay will address social issues concerned with the volcanic eruptions. As it is an interesting topic, I will be writing about two volcanic disasters. Firstly, I will discuss the A.D. 79 Eruption of Mount Vesuvius. Secondly, I will talk about the 2013 Eruption of Sumatra Volcano. Later, I will be making a comparison between the mentioned volcanic eruptions and the damage they caused.
The question is what causes volcanoes to erupt? An eruption starts when there is a pressure on magma chamber. This pressure forces magma to rise up through the conduit and come out ...

When Lilacs Last In The Dooryard Bloom’d

The Poem entitled “When Lilacs Last In The Dooryard Bloom’d” is Walt Whitman’s romanticized story of an American leader during a trying time. In his poem, he shows the audience his own meaning of democracy as well as racial equality. His poem speaks of Abraham Lincoln as the one who brought about racial equality in a land that was being tried. This was during the time of national disagreement, when their great leader fought for equality and abolitionism. This was the most prominent theme seen in Whitman’s work here.
He speaks to the deceased president about ...

- What is a Volcano?
A volcano can be described as a mountain that leads to a pool of molten rock present below the surface of the earth. Upon building up of enough pressure, an eruption of the molten lava occurs. Eruptions can cause lava flows, hot ash flows, lateral blasts, avalanches, mudslides, falling ash, and floods. Tsunamis and earthquakes are also possible consequences of such volcanoes (Wicker).
- Formation of Volcanoes
When the magma from the Earth’s interiors erupts to form lava deposits and ash flows on the surface due to pressure, a volcano is said to ...

A)Pathophysiology of crocidolite.

Pathophysiology refers to both the pathological and physiological effects of a disease or injury. Crocidolite is a type of asbestos which is blue in color which has very thin fibers hair like fibers. This makes it the most dangerous type of asbestos as these thin fibers are very easily inhaled when blown by the wind where the asbestos occurs naturally (Australia) and when people are working with it especially during mining. This type of asbestos is used mainly for insulation as it is sprayed on walls, ceilings, boilers ovens and pipes.

I was wounded the one first time I considered Why are we here? When I wasn’t concern with The Meaning of Life, I was content. My comfortable state ignorance was reserving prayers for Christmas Eve, and Fantasy creatures peopling my imagination. I questioned nothing and accepted nearly anything for what it was. In short, I took the absurd seriously. Possibility was my rock. It would be the heaviest pebble I should ever keep as I experienced a moment too soon in my adolescence that there was no meaning in life. I became conscious. The adults around me lacked ...

Our scientific understanding of the vastness of the universe and the relative insignificance of Earth and human civilization on a galactic scale increases every day. The first planet outside our solar system was discovered in 1992, and since then, hundreds have been found. A study done at NASA’s Jet Propulsion Laboratory in 2011, for example, estimated that the Milky Way Galaxy alone should contain about 2 billion Earth-like planets. If this estimate is accurate, then the statistical likelihood that at least one, if not more, has also evolved life, possibly even intelligent life, is higher than ever before. ...

REPORT: Landscape Planning and Ecological Management: Plantation of bare root common trees.

Introduction
We often take trees and other flora, all around us, for granted maybe because almost all of us have seen trees and captured the word and their image deep inside our sub-consciousness. As we grow up, we learn about the benefits and advantages of trees parrot-fashion. No person or entity teaches us anything about the aesthetics so when we see captivating landscape photographs and images, we take in the beauty without taking in the trees. It is beyond this point that most of us change directions and go off towards modern, fast-process systems, which we then proceed to ...
