Advancements in aircraft reciprocating engines

Introduction There is a misconception that because modern aircraft engines built by Lycoming, Continental and other companies have similar look to engines used in general aviation aircrafts of the 1970s, there have been no technological advancements in this field. Even though new engines haven’t changed much by outward appearances, aircraft reciprocating engine technologies have advanced dramatically in past two decades. The overall build quality of engine has greatly improved. Advancements in machining technologies and automatic manufacturing processes made it possible for aircraft engine makers to enhance machine’s durability. Many components of piston engines have been significantly improved, ...

The human race has harmed the very planet that they live on, through their activities, since the very start of civilization. Using the resources provided by nature to fulfill the needs of the human beings is not something that is the cause of concern, but the indirect intent of incriminating damage to the environment is what the main source of concern is. Some of the impacts of human activity involve the disruption of carbon cycle, the disruption of hydro (water) cycle, and the reduction of species diversity. The major impacts of human activity on the carbon cycle include the ...

Global warming refers to the phenomenon due to which the average global temperature rises by a few degrees over a specified period of time, or as the time passes. The concern that this raises is that if the temperature keeps on rising every few years or so, it is not hard to imagine what would be its effects to the global climate and environment over the next few decades. The rise of a few degrees in a few years is not much of an issue; however, if this rise is consistent, that is where the concern of most of ...

Introduction

David Rockefeller is among the richest people in the world, but his wealth is connected to the family empire that was established by his parents. He is the last born in the family, and his success started when he was working as the chair of the Manhattan Chase Bank. His family’s investment in the fossil industry has immensely contributed to the growth of the Rockefeller Empire. Although he has managed to amass significant amounts of money, his organization has been criticized for engaging in unethical practices by influencing the country’s policy making process. A good example is ...

Globalization

Carrier is a major organization and a subsidiary of the United Technologies that has operations in 6 continents and in 170 countries where it seeks to provide consistent, noiseless, and energy-efficient products to its huge consumer base. The expansive presence in the global market is an opportunity for the company to introduce products into the market, enforce partnership, and foster innovation. However, Carrier faces stiff competition from cheap products from China especially in developing areas. To reduce operational costs, the company has instituted several strategies such as developing operational and manufacturing plants outside the United States. Like many other ...

Introduction

The issue of global warming has recently become more contentious. Ideally, a great debate exists among numerous individuals on whether it is real. According to MacMillan (Par. 1), the average global temperature over the past fifty years has risen at the most rapid rate in recorded history. In essence, the climate scientists connect the warming of the oceans and atmosphere, a strong decrease in the sea ice, and ocean level rise, among other climate-associated changes to the rise in the global temperature. The greenhouse gasses including carbon dioxide, water vapor, methane, and nitrous oxide contribute to global warming by ...

Energy has played an important role in building the world economy today. From enabling man to perform daily activities to enhancing the functioning of many industries, it is sensible to state that energy is of great importance to the world. Due to its importance, fossil fuels such as coal have thus been burnt down to create energy. However, different negative effects are associated with burning such fuels to the environment. For instance, global warming gasses are emitted thus, causing global warming as a result of carbon monoxide, which is emitted while burning coal. Despite their disparities, both developed and ...

The development of human society is inextricably linked to the use of our planet's natural resources, with the consumption of various types of energy in ever-increasing scale. All the achievements of modern civilization - a huge variety of goods, different in speed and comfort, transportation, space travel, etc., are possible thanks to the huge amount of artificial energy, which produces humanity. The basis for the production of thermal and electric energy is the process of burning fossil fuels -coal, oil, gas. The scale of the production and consumption of fossil fuels, metals, water, air for the production of essential ...

INTRODUCTION

One of the most heated debates of the modern era revolves around environmental issues and how best to repair current damages and prevent future damage. Unfortunately this is something of a controversial topic because there are some that heavily support the environment and the protection of it and there are others that actually do not believe that environmental issues are serious at all. That being said addressing a problem that some people will not admit exists is incredibly difficult. This is the case with the modern issues with air pollution.

Summary Report 1

What factors contributed to the problem? Volcanic activity is a major contributing factor to the issue of climate change. The eruption of volcanoes leads to the release of large quantities of water vapor, ash, dust, carbon dioxide, and sulfur dioxide into the atmosphere. In the atmosphere, these sulfur dioxide molecules will react with water vapor leading to the formation of sulfuric acid, which is then spread all over the world through winds. The sulfuric acid formed in the atmosphere can significantly affect the amount of solar radiation entering the Earth’s surface and thereby the ...

Introduction

Every parent envisions a future where their children and grandchildren live in a rich and resourceful environment that essentially provides them with everything that they need to survive. However, what if parents were informed of a pending doom where their children will live in an extremely toxic environment where there aren't enough basic resources such as fresh drinking water or where the climate is comprised of harsh conditions that threaten their lives on a daily basis? What if they were informed that by the time their children are adults, a diverse range of the existing species of animals will ...

Effectiveness of Carbon Tax as Environment Policy

Climate change has emerged as a global challenge because unrestrained rising of global temperature would cause melting of glaciers and rise of sea level that would submerge land masses, change weather patterns with frequent incidence of hurricanes and floods and droughts. As an effective response to the challenge, global leaders have agreed to cut back emission of Green House Gases (GTG) to contain the global rise in temperature below 2 degree Celsius (Symon, 2013). Carbon dioxide, a major constituent of GTG, is released to the atmosphere on combustion of fossil fuels such as coal, oil, and ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Abstract

The concentration of carbon dioxide has been abnormally increasing over the years. In the year 2016, its concentration exceeded the limitations, and has been considered as a dangerous situation. As a response to the increasing carbon dioxide content in the Earth’s atmosphere, different processes are being suggested in order to lower the concentration. Carbon Capture and Storage, or CCS, is one of these processes. Generally, there are three different phases of this process: the pre-combustion, the oxyfuel, and the post-combustion. These three phases have different processes in which the carbon dioxide content is being separated from the other ...

Introduction

Certain factors such as the need to conserve environmental purity as well as the increasing pressure on fossil fuels have prompted the increased use of alternative sources of fuel, renewable energy to be precise. Renewable energy has been cited as not only cheap to exploit but also the most environmentally friendly sources of energy due to the reduced instances of environmental pollution associated with such energy (Pasqualetti 204). Solar energy, for instance, has been largely exploited globally due to its free availability, especially along the tropics where it is abundant throughout the year. Despite the increased preference of solar ...

Ethical Issues

Human trafficking is a worldwide problem. For all practical purposes, this activity is nothing but a form of modern slavery. Every year, about 21 million people are caught up in human trafficking from about 130 countries around the world. Without a doubt, this is a serious issue given that it violates human rights that the United Nations takes very seriously - and should. While this pertains mostly to women who are sold into prostitution while also involving children and young boys as well who are coerced into forced labour as well. Given the atrocities around the world, the purpose ...

Question 1 Tectonic plate motion refers to the movement of continental and oceanic plates from one place to another due to the effect of forces that generally act on these plates. These movements cause some effects to the surrounding environment and even to the earth surface in general. A scientist by the name of Wegner had earlier on formulated a theory that instituted some of the facts and evidence backing this presence of continental drift that had happened some time back in history (Runcorn, 2013). Furthermore, the critical evidence in support of continental drift is the jigsaw fitness of ...

Introduction

If any organisation were to succeed in achieving its objectives and targets, it is at the mercy of the strategies that it develops for itself. A lack of strategy will tell on the manner the organisation works. Hence, the team employed to this effect should be efficient and have the required knowledge for the same. Plans should match what the company envisions for itself in the light of its finances and operations. Such plans work in the long run. The more changes occur in them, the more difficult it is for them to move ahead. Realistic yardsticks can be ...

Exercise 1

 Driving in winter, especially on snowy, icy roads can be less troublesome if you take a few simple precautions. First, put on snow tires if you plan to drive on snowy, icy roads very often. Second, check the amount of anti-freeze in your radiator and add more if necessary. Next, add antifreeze to your windshield washer fluid; otherwise, the fluid will freeze and possibly break the container. Finally, it is also a good idea to carry tire chains, a can of spray to unfreeze door locks, and a windshield scraper in your car when driving in winter weather The ...

My Relationship with the Environment

“You look at that river gently flowing by [] it's peaceful. And all of a sudden, it's a gear shift inside you. And it's like taking a deep breath and going, "Oh yeah, I forgot about this.”” – Al Gore, The Inconvenient Truth (2006). The environment. Since our birth to the world, anything that happens to it affects us in so many ways. We hear it being mentioned in a lot of our current events - something is wrong with it, and that something must be resolved soon. The thing about the environment is that all the problems related to it ...

Introduction

As the need for energy conservation and preservation of the environment becomes more popular, many countries and firms are now utilizing renewable energy in order to generate power. Renewable energy, also known as green energy, is defined as the energy that comes from natural resources which can be replenished constantly, such as sunlight, tides, wind, biomass, and geothermal heat. Because the sources of this energy can be constantly renewed, it can be said that this type of energy cannot be exhausted completely (Ciolkosz).

Why Use Renewable Energy Sources?

There are many advantages in using renewable energy. First off, renewable energy is environmentally sustainable. Unlike ...

Global Warming Phenomenon

The issue of global warming has been a critical problem across the entire world due to the effects associated with this condition. Global warming is caused by the increase in Earth's temperatures due to the effect of greenhouse gases. The greenhouse gases, such as carbon dioxide emitted from burning of fossil fuels like coal, oil, and natural gas to provide energy are responsible for trapping heat and preventing it from escaping from the Earth’s atmosphere. Human activities like cutting down trees and burning forests for farming activities has been attributed to the emission of greenhouse gases that are ...

Despite pessimistic evidence to the contrary, many people believe that our current episode of global warming is part of a continuing cyclical climatic process that has been occurring for thousands of years and is not caused by humans. This optimistic view is based on selective choices of research by the proponents of the “natural process” scenario and is not necessarily based on the collective global research of climate scientists. The results of this optimistic viewpoint could be that governments fail to take positive action to address the problem of climate change, resulting in our planet becoming uninhabitable. In discussing ...

Introduction

Globally, clean air is a critical resource for the general public health while a clean environment is one of the essential elements required for the establishment of sustainable societies. Human beings breathe the air around them and thus air pollution or any pollution manifested in any other form to the environment directly affects their overall health and wellbeing. This has the implication that public authorities at international, national and local levels have the responsibility of protecting the quality of the air through development of regulations that regulate the use of products and materials that have the potential of causing ...

An issue that has been a main concern in politics has been climate change and of course global warming. Everyone wants to know if the activities of humans are changing the climate. They also want to know if it is possible they will encounter more serious disasters. However, it is difficult to provide answers as their concerns are quite challenging to those who are responsible for solving them. But it is important for all those that have concerns to understand that many new things are happening that were not predicted in the early 20th century. This is why I ...

Introductory remarks

Alberta oil is one of the largest oil fields in the world. According to Simon Dyer, “The Canadian oil sands are the second largest proven oil reserve after Saudi Arabia” (Dyer, 2009). The commercial development of the Alberta oil sand had begun in the late 1960s. By the time World War I had arrived, and after the war was over, Canada was almost entirely dependent on oil from foreign countries. Canadians, after the war, began to wonder if the nation had any oil resources of their own. This interest led to the creation of the Alberta Research ...

One concept that our political leaders like to kick around a lot is the notion of equality. It is one of the founding concepts in the American Constitution, and it was one of the three principles in the French Revolution (liberty, equality and brotherhood). It is one of those words that draws people along with it and resonates, because none of us wants to have less than those around us. In the area of energy, as Dr. Vandana Shiva points out, there are two competing modes of equality. One has all people elevating their standard of living, in terms ...

Executive Summary

Fossil fuels are the predominant source of energy for industrial and transportation consumption. It is however expected that in a few more decades, fossil fuels will have lesser role to play than non-conventional oil and gas sources and renewable energy sources. This paper presents an overview of some of the socioeconomic factors that are driving the global oil industry and their implications for the UK industry. Four key influences are studied to understand the implications for the industry in terms of economic and environmental factors. The steady influence of OPEC is a significant factor in the pricing of crude ...

Introduction

Contemporary business, political and social environments have changed under the influence of globalization, consequent internationalization of business portfolios, size and scale of the activities and even the tremendously increased international mobility of individuals. It is difficult to argue that the future of the Oil and Gas industry have changed with the growing influence of OPEC, economic growth, observed in non-OECD countries and climate change policies and legislation around the globe (Martin, 1995). The access to the new fossil reserves and the changes in the distribution of these resources also have had a significant impact on the ways the future ...

Homework Assignment # 2: Sustainable Communities

Part 1: Community Observations A closer view of my city which is Corvallis Oregon reveals that there is a general lack of sustainability regarding the three dimensions including ecology, social equity, and economy. Most people still get to work using public means of transport which pollutes the environment hence is not sustainable. Further, there are very few locally produced foods available in the community and the number of green spaces like parks, trails and greenways are not that many though there are a few of them around. There is only one gathering place for the community which is a ...

Overpopulation is the most serious problem faced by humans today. Population continues to expand at an alarming rate forcing depletion of natural resources. The demand for food, shelter and water causes havoc on the natural biodiversity of the Earth. Many species of plant and animals are eradicated and the freshwater resources are drained beyond recovery. The existing resources are not sufficient to sustain the increasing population. The increase in the demand for consumption of goods has led to a change in the cultivation pattern resulting in biological imbalance. Changes in the size of population affect all issues which range ...

The issue of the pollution of the environment has been an issue that has always been addressed in different forums. This is mainly due to the fact that the continuous pollution makes the world less inhabitable for man. Pollution may be on different components of the earth; from water, to air to the ground itself. Various mechanisms have been developed as a way of ensuring that we are able to conserve the environment (Shaw 14). These may include measures like ensuring that the citizens use biodegradable products in order to prevent the instances of soil pollution, or ensuring that ...

The majority of energy used in the world consists of fossil fuels, such as oil and coal. However, at the current usage rates, the Earth will run out of fossil fuel, and the population will have an energy shortage. Many researchers are now looking into renewable sources of energy to combat the threat of exhaustion of our current energy sources. Renewable energy sources are ones that use the aspects of the Earth that cannot be consumed, and therefore, we would never be depleted. Waterfalls, wind, and solar power are three renewable sources of energy that people are using today. ...

If you pay attention to too much of the mass media, you might think that renewable energy is a pipe dream proposed to solve a nonexistent problem. After all, the presumptive nominee for the Republican Party in the upcoming U.S. presidential election, Donald Trump, sat down with the editorial board of the Washington Post back in March and told them, “If you look, they had global cooling in the 1920s and now they have global warming, although now they don’t know if they have global warming” (Leber & Aldern 2016, web). Trump has even gone so far as to ...

In my opinion, climate change presents a fundamental problem in our world, and the species, places, and natural resources that are present in our world. The results of climate change are real as ocean levels have risen, and the planet is becoming warmer. Due to global warming, the world is experiencing intense and longer droughts that threaten wildlife, crops and freshwater. The increased global temperature has significantly altered the planet’s climate, and the result is extreme and highly unpredictable weather conditions. Climate change causes intense heat waves that are melting the polar ice caps and rising ocean levels, ...

In the article Why Bother, the author Michael Pollan discusses that the planet is at a great risk due to climate change and the immense carbon emissions yet ‘we’ the people have so far done nothing fruitful to counter the issue. He writes about Al- Gore and his proposition about saving the planet by changing one’s light bulb (Pollan). The problem is far more rooted and intense than this mentality. He says that this impassive and carefree attitude is the reason why even if one person on the planet starts making a change with their lifestyle and habits, ...

Human trafficking has become the modern form of slavery. It affects more that 27 million individuals in the globe. The scope of the practice is difficult to validate since most of the human trafficking operations occur as hidden crimes. The most prominent type of human trafficking that continues to enslave many people is sex bondage. Before pursuing the criminal justice course, the knowledge I had concerning sex trafficking was limited. I was not aware of the factors involved in the activity and the number of people who have succumbed to it. I also did not have sufficient information about ...

Importance of Entrepreneurial Activity to the UK Economy

Assignments 2 Introduction The constant growth and evolution of economic relations, both between countries and between entrepreneurs within a country, are requirements for the creation of new business forms. Entrepreneurship is an important, but not a sufficient factor in economic and social developments of countries (Waschik, Fisher and Prentice, 2010). However, if left uncontrolled by the state, entrepreneurship can become just as harmful as the administrative-command system in an economy. Entrepreneurship is essential for the development of a competitive economic environment; in order to give the final consumers the freedom of choice, but does not content with goods offered ...

Global warming is the excess greenhouse effect caused by various factors that rise earth’s temperature beyond an optimum level, causing adverse impacts to the biosphere. Earth’s temperature is determined by the amount of solar radiation received from sun, radiation reflected or absorbed by various gases in the atmosphere as well as various surface features such as snow, water bodies, built environment etc. (US Environmental Protection Agency, 2016). Natural as well as anthropogenic factors contribute to global warming and associated climate change.

Martin Luther King Jr.’s historical speech “I Have a Dream” has been a pivotal moment in history for black America. As a leader of the Civil Rights movement, MLK had a great vision of justice and equality for black men, women, and children that had not been honored by white America. Despite the signing of the Proclamation of Emancipation a hundred years prior to MLK’s speech, black people still lived segregated and in oppression. It was MLK’s brave and courageous stance that empowered black people throughout America to begin the non-violent fight for what should have ...

It is the duty of each and every person to take care of the environment and further to have in place an environment that will enable the world regenerate and in turn be favourable for the day to day living of man today and the future. Various measures have been put in place in order for this to happen. These include the coming up with the bio-degradable products and further, to look for the alternative sources of energy that reduce the amount of harmful emissions. One of these methods is the coming up with the green cars which are ...

Introduction

The concept of sustainable development was first introduced in 1987 by the United Nations as part of the Report of the World Commission on Environment and Development, in which it was stated that sustainable development implies “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (United Nations General Assembly, 1987). The World Conservation Strategy published in 1980 served as prelude to the conception of this notion, as the UN recognized the importance of minimizing the impact of human activity over the earth’s ecosystems and adopting models inclined towards sustainability ...

Introduction

There is a significant part of the population that appreciates the science fiction. Science fiction is, in fact, a branch of speculative fiction that covers highly imaginative concepts that are often related to the fields of technology, astronomy, physics, and even socio-anthropology. What makes science fiction interesting and highly patronized is that it scratches the humans’ itch for discovering endless possibilities. After all, humans are avid explorers. They, as a species, tend to focus on something that they cannot get or make, set it as a goal, start a quest to be able to accomplish that goal, and then ...

Introduction

Much recent publicity surrounding climate change has focused mostly on global warming, but little direct correlation has been given in the media with regard to the impacts that environmental pollution has on climate change, and also on human health. Although studies of pollution and the environment have been carried out since the time of the Industrial Revolution, it only relatively recently that attempts to measure environmental on a global scale have been undertaken. Environmental pollution is a major cause of global concern, not only for the effects that it has on the physical environments, but also for its potential ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Importance of Entrepreneurial Activity to the UK Economy

Introduction Constantly growing and developing economic relations, both between countries and between participants within a country, are prerequisites for the creation of new forms of business. Entrepreneurship is an important, but not the only factor in economic and social development of many countries (Waschik, Fisher and Prentice, 2010). However, uncontrolled, no adjustable (wild) business (without the supervision of the state) is just as harmful as the administrative-command system. Entrepreneurship is essential for the development of a competitive environment, in order the final consumer of products has the right to choose, but does not content with goods offered to him/her ...

Abstract

This essay briefly describes the meanings of the first law and the second law of thermodynamics. Thermodynamics, as the name illustrates, is the field of science where the dynamics of quantities including but not limited to heat and temperature and their relationship with energy, work, entropy etc are dealt with. The first law of thermodynamics is a version of the principle of conservation of energy. It establishes a theoretical limit on how much work can be output when a certain amount of energy is available and vice versa. The second law of thermodynamics is a bit more subtle and ...

Question 2: Energy and Risks

Energy is fundamental to life. Without the resource, billions of individuals would remain hungry and cold. The prominent source of energy emanates from fossil fuels such as natural gas, coal, and oil in the developing and industrialized nations. Despite providing numerous benefits that sustain human, plant, and animal life, the fossil fuels also present disadvantages that have resulted in ecological damage, political disruption, and production failures. This paper attempts to compare the political and environmental challenges introduced by natural gasses, coal, and oil as well as possible remedies that can alleviate the problems. The greenhouse emissions that arise from ...

In today’s world, climate change is one of the most critical and daunting issues that humanity is faced with. It has emerged, both as a major scientific and a global public policy issue. There is broad consensus among the scientists of the world that accumulated carbon dioxide, which is a greenhouse gas and is released as a result of burning of carbon that is stored in fossil fuels, is causing a rise in the average surface temperatures around the world. Other greenhouse gases such as water vapor, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), nitrous oxide and methane, which are emitted ...
