The issues of global warming, climate and weather have been discussed for a long time. Weather can be defined as the frequent changes in aspects as the wind, sun temperatures, and rainfall either on an hourly or daily basis. On the other hand, the averaged patterns in weather changes over a given period of time, probably a decade or more, can be described as climate. In the same context, global warming falls under the changes that have been impacted by climate over a long period of time by human activities and worsening environmental problems (Climate Modeling 101: Climate vs. ...

Question: what is the appropriate method of identifying compounds as either ionic or covalent based?

Background/Hypothesis Ionic compounds are created from the strong electrostatic bonding between ions (Brinker, and George 393). The covalent compounds have are formed by bonds that result from sharing of electrons (Mah 31).

The model of assimilation refers to a group of people integrating into a new culture assimilating its host's cultural elements such as language and customs, losing some or almost all of its original cultural elements. An example of this model is the case of Argentina which has open immigration policies and received a growing number of Chinese. These integrated in such a way that they have assimilated their hosting language, Spanish and the way of Argentinian living, doing business, and social life. The first generation of immigrants continues speaking their language. However, they left behind many of their cultural ...

Rapid prototyping is a set of various techniques that is usually used for fabricating a model or a sample using 3D computer aided design. The rapid prototyping allows prompt and effective collection of data necessary to produce a sample or a particular detail. Historically, the method was used to convert drawings into fabricated samples and details. However, the entire group of techniques is comparatively recent, as the first available options became available with the advancement and penetration of digital machines. The development in rapid prototyping is a result of progressing technological advancement and a high demand in machine tool ...

Abstract

The process that led to the formation of the United States is more of a salad bowl than a melting pot; ethnic communities were not softly absorbed to the umbrella of American culture, but they rather coexisted in their individual identities, like ingredients of salad on a plate. The struggle of the African American is pinned on his slavery and the fact that he was sold to America for labor. It has been very hard for the African American to get assimilated, and the situation is still dire today, as racism is still rife. The underrepresentation in the Congress ...

Kotter and Rathgeber, in their simple fable, Our Iceberg is Melting, described a scenario which involves leading through change. The authors’ fable has a lot of lessons for leaders who wish to lead successful organisational changes. According to Kotter and Rathgeber, successful organisational change requires a step by step approach. The authors suggested an eight-step procedure for leading organisational change. The authors used a colony of penguins as the characters in their fable. The Penguins, unknowingly, employed the eight-step procedure to implement a successful change. According to the authors, a challenge which is well-handled can lead one to prosperity ...

Cross-cultural psychology is the scientific study of the similarities and differences between cultures and how human’s interact with one another. The fundamental processes of human behavior are developed and shaped by culture. If we use America as an example, it has been described globally as a melting pot of cultures. There are numerous ethnic groups in the United States. As culture, race, ethnicity and class come together a new multi-cultural generation is being formed. People in different cultures have a different view on life because they live very different lives. Americans have a unique heritage because the majority ...

Assimilation

Assimilation is a term which is so much associated with immigration. Its significance is not only felt in today’s immigrant communities but also throughout the history of the US. Previously, the term was used to mean a biological process carried out by the body used in the conversion of food into a substance which can be absorbed in digestion. However, the use of the term in today’s world as a physiological process has been eclipsed as a result of its greater social significance. Its broad use is evident by the many definitions it carries. Some sources define ...

Electrophilic Aromatic Substitution to yield 4-Bromoacetanilide

Introduction Halogenation is a common process in organic synthesis. It is used in industrial and research synthesis as halogenated compounds are used for numerous widely used goods, including plastics. The lab aimed to perform monohalogenation of acetanilide. The reaction is specific since it is performed without catalyst. The typical halogenation is realized in presence of Lewis acid. Halogens molecules are electrophilic, and do not actively react. In presence of Lewis acid, the interaction is rather active.2 The lab used catalyst-free halogenation. The acetanilide molecule contains the acylated amine. As a result, the electronic density is shifted towards the amine ...

Abstract

The impact of salt on melting of ice can be described as utilizing atomic progression recreations. The harmony the point of solidification melancholy saw in the recreations is in great concurrence with trial information. The dynamic parts of liquefying are examined as far as the trading of water atoms amongst ice and the fluid stage (Brique, 1967). The ice/fluid harmony is a profoundly dynamic procedure with the incessant trade of water particles amongst ice and the fluid stage. The parity is irritated when ice dissolves and the softening continues in two phases; the restraint of the relationship of water ...

(Dali Web) (Lipton Web) Modern advertisements often take over the ideas from the higher art and fulfill it in order to advertise their product. The very famous tea company Lipton had borrowed Salvador Dali’s idea of melting clock. While looking at these pictures it is hard not to mention how much they are alike. The visual effect both of Lipton advertisement and Salvador Dali’s artwork “The Persistence of Memory” use the similar effect of melting.

Research Question- Why is it a problem if the earth’s average temperature gets a little warmer?

1.1 Results The average rising temperature can have vast impacts only by slight increase. The vast impact the average temperature can have can be shown with the average temperature in the last ice age, when the average temperatures were only around 5 degrees Celsius lower than today’s average temperatures. From the Figure 1 it is seen that the global average temperature, which combines the surface and ocean temperature have been on the rise and have reached the highest levels in the ...

In the late nineteenth century, America went through a time of progress that was later dubbed the Gilded Age. The Gilded Age is known as a time of economic prosperity, industrial advancement, and population growth. However, the era included many dark times that are masked under the guise of progress and prosperity. The economy took a downward spiral, discrimination was rampant, and corrupt politicians worked with wealthy businessmen to concentrate the country’s wealth in a small population of people. Despite the tough circumstances that were caused by a boom in population growth, immigrants remained a large portion of ...

The documentary film "Chasing Ice" is an award winning documentary about the unprecedented depletion and melting of ice mass and glaciers due to climate change. The documentary features the incredible video-graphing project headed by James Balog together with the Extreme Ice Survey. In this documentary, the viewers would be appalled by the truth behind ice calving and the melting of the ice, and how fast they melt due to global warming. As one of the viewers, I was stunned by the documentary, specifically because the documentary showed how quickly the ice are melting. In about a short period of ...

Global warming is the rise in average global temperatures. The rise in global temperatures is occasioned by the emission of greenhouses gases such as carbon dioxide, carbon monoxide, methane, and nitrogen oxides. The gases are released from industrial process that combust fossil fuels such as diesel, coal, and petrol. Such processes include generation of electrical energy in thermal power stations, burning of coal in industrial boilers, and combustion of fossil fuels in internal combustion engines. When these greenhouse gases are emitted, they rise to upper levels of the atmosphere and form a layer that blankets the earth. This layer ...

The heat was intense. The orange light shone on the desert, drying up the remaining puddles of water into vapour, rising into the atmosphere. A lizard crawled slowly, almost dying, parched and with a hide so leather like, one would think it was crisp fried. Slowly, I heard the intense ringing of the siren. Waaang waaaang waaang. It was time to get inside our shelters. The shelters were not made of concrete. Unlike the olden days, concrete was the material of choice. All buildings were once made from stone, from cement mixed with water to form hard solid blocks. ...

Winter sports industry cannot ignore the consequences of climate change. Over the past three decades, the picture of mountain precipitation becomes more unstable, causing that fact that the ski season has to be shorter. In 2004, the lack of snow has led to the closure of four resorts in Scotland. In the spring of 2012, a sudden thaw has led to the melting of snow in Ottawa, Canada, with the result that the resorts were closed before the end of the season. In Bolivia, the highest ski lift in the world, standing at an altitude of 5395 meters in ...

SUMMARY

Global warming is a serious issue that threatens the survival of future generations. Various methods are being devised to reverse the effects of global warming such as the use of green energy. Motor vehicles running on fossil fuels produce greenhouse gases which are a major cause of global warming. Therefore, it’s almost impossible to address the issue of global warming without considering emissions from the transport industry. Electric vehicles are a viable and environmentally friendly alternative to internal combustion engine vehicles that combust fossil fuels. The vehicles are powered by a rechargeable battery that drives an electromagnetic motor. ...

I. Introduction Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

In the winter prevalent nation, skiing is a sport as well as a leisure activity for many. This activity is favored by the snowy conditions, in particular on the continent of the extremes of the tropics. According to (SkiCanada.org, 2013), skiing is a sport that takes place by sliding down the snow covered mountains using fixed metallic rods to facilitate sliding. However, with the rapidly changing climate, the world is paying the price of the global warming. This, therefore, poses a challenge to the ancient skiing activities as the amount of snow keeps on decreasing at alarming rates. The ...

Amongst the biggest problems that are being recognized is the phenomenon of global warming. This is an alarming issue for the environmentalists as they believe that the sustainability, worse yet, the livability of the planet is at stake because of it. Because of the economic and industrial conditions of the planet, the climate of the earth is changing rapidly. The average temperatures that are being measured are increasing very quickly, and it is feared that in a short period of time, the temperature of the planet will rise higher than what is comfortable (Root). The problem of rising temperatures ...

Introduction

For one to achieve success in any given casting practices, there must be a proper control in the variables required during the process. The variables may involve certain characteristics of the alloys, and metals used, the casting method, design of the mold, material of the die used, and the parameters used during processing. The casting quality is influenced by the cooling rate, gating systems, and the evolved gasses during the entire process. Precautions must be, therefore, taken to avoid defects during metal casting design. This paper also outlines the economic factors that are relevant and basic in casting operations.

Chemical Weathering

Chemical weathering in the mid-latitudes is the process where rocks are weakened and disintegrated by chemical reactions that occur in the soil. Some of the chemical reactions that cause chemical weathering are oxidation, carbonation, and hydrolysis. These processes are involved in either forming or destroying minerals and therefore altering the nature of the mineral composition of the rocks. The process of chemical weathering on rocks characterizes the second stage of rock disintegration. The first process occurs during physical weathering and it involves disintegrating rocks into small pieces which are further broken into smaller pieces by chemical weathering. The most ...

The following analysis of Persona and Solaris reveals how movies from unlike countries and of different genres portray the development of opposite human personalities while losing or gaining humanity under the external influences and internal self-recognition. The attempts to create a fine movie about internal and external of human life do not often impress much, especially nowadays when we experience an endless flow of visual images. Probably, it inspires people to look back at the classic works that not only represent the unusual transformations in the forms of self but also produce extraordinary rhythms in the scenes (Tarkovsky 113). ...

Historically, one of the issues that the United States has been accused of is having a lack of cultural identity that extends beyond the hamburger. Actually, the irony in that sentence is that the hamburger is not even American, which further proves this argument. What these two sentences are attempting to say is that there is very little that the United States does have compared to nations in Europe and other parts of the world that have longer histories that the Untied States does. This is not to say that the United States will not develop this over time; ...

Salvador Dali is one of the most renowned and prolific artists in the twentieth century. He is perhaps recognized for his reputable artistic works such as the painting of melting clocks in the Persistence of Memory. He started his passion for art during his childhood when he attended his first drawing lesson and claimed that he exhibited hysterical, rage-filled explosions concerning his playmates and family. Throughout his life, Dali has shown his love for Catalan culture, and he has portrayed the landscape environment of Figures, where he was born, in his paintings during his career (The Art Story, Sec. ...

There is no controversy regarding whether there is a climate change on earth or if there is real climate change. The controversy is as a result whether the human is a fundamental cause of the climate change on the planet and to the enhanced greenhouse effect, or whether the changes in climate is attributable to the natural cycle that has existed in the several years ago. Always, there are natural tendencies that affect some places of the world more than the other regions, but loads of studies and scientists assert that the climate changes are the causes of the ...

Abstract

Adequate clean water is essential for the health of every living thing on this planet. Humans create tons of pollution, effect the weather patterns that cause droughts, and there is a history of over-use of the aquifers in the form of wells and pollution from fracking which are detrimental to the survival of all living things. Global climate change, especially since the Industrial age began, has affected the entire planet in various ways. There have been larger storms as a result of climate change. There are serious droughts because of climate change. The ice caps are melting because of ...

Introduction:

The debate surrounding global warming is important due to the growing concern of potential consequences for not only humans, but all that inhabit the Earth. A changing climate produces uncertainty regarding the future, which places a great deal of stress on human institutions as well as the natural ecosystem. However, others argue that the effects on the environment are primarily natural processes and were not impacted by human behavior. In assessing the current state of research regarding this debate a better understanding of the contribution that various activities have on the climate can be attained. This can help to ...

Montreal is concentrating on making the city appealing to the general public and by extension the entire globe. Considering the possibility of wider and heated sidewalks alongside fewer cars and more trees, Montreal has decided to launch the future of Saint Catherine Street. The street being the most important in the city requires innovation, flexibility and audacity in an effort to offer a description of the dynamic and greener look on the streets. The street is the largest and this means it requires more attention than any other street in the country. There is a dire need for infrastructure ...

1. Introduction Global warming consequences have been mainly focused on the impacts they have and will in the future have on the global human population. The less focus is on the impact on the animal and plant species that are even more vulnerable, since they cannot adapt to quick changes as humans can. They are not the main culprit for the climate changes and yet they will suffer the most. One of the animal species that is being threatened by the global climate change are also polar bears that inhabit the polar region. They are playing an important role ...

The United States has a traumatic and brutal past in relation to African Americans. This sad legacy of slavery, it would be accurate to say, translates into many diverse fields even though litigation and other institutions keep it check. This being the case, the performance industry has not been the African American’s best friend culminating in black face and other fraught phenomena. However, in the twentieth century, or rather, the second half of the twentieth century has embraced diversity in an unprecedented way. This trend is what gives rise to a renaissance of artists stemming from diverse backgrounds, ...

Melt spinning refers to a method that is used to cool liquids in a rapid manner. The method involves the internal cooling of a wheel using liquid nitrogen or water. The wheel is then rotated as it cools. A liquid is streamed onto the cooling wheel, and that causes it to solidify rapidly. Melt Spinning is used in the development of objects that demand high cooling rates for them to form. A good example of such material is metallic glass. Polymers that can undergo melting use the melt spinning technique (NPTEL, 2010). Examples of such polymers include polyester; sulfur; ...

Water equals life because without water there is no life. Water constitutes two thirds of human body weight: the human brain consists of 95% of water; the blood contains 82% of water; and people’s lungs are made up of 90%. That is why people cannot live without water and are in constant need of it. The same can be said about animals and plants. In other words, all living organisms depend on water. And though water covers 70% of the earth’s surface, there is still a need in it. There are several reasons for it. Firstly, not ...

America is the home to a number of cultures, race, and languages. On a daily basis one can hear Spanish, Chinese, Arabic, and a variety of Caribbean dialects in the workplace, schools, homes and the neighborhoods. The truth is that the United States is the “melting pot” for a number of immigrants who bring different cultural and linguistic framework to the language that is spoken in the United States. Each cultural group brings new variations to the language and culture of the United States and has created a "bi-nationalism" concept. For some critics, the United States is no longer ...

Article “Antarctic ice may melt more quickly than expected”

The first article published on CBC news describes the problem of melting of the glaciers in Antarctic. According to the article, it is expected that the sea level would rise by 46 to 86 centimetres by the year of 2100, which is much more that it had been expected before. The scientists identified that the main reasons of this are warmer air, less frigid water and gravity. Moreover, the forecasts also predict that by 2500 the seas might become 13 metres higher, which will be caused only by ice melting. However, as scientists believe, the rise of the sea ...

On March 28, 2016, National Geographic published an online article about the increased risk of earthquakes and its correlation with the human activities (Gilman, 2016). Most people believe that earthquakes are natural hazards caused by tectonic plate movement, but the article written by Sarah Gilman shows that earthquakes in Oklahoma region including some parts of Texas, New Mexico, Kansas, Colorado, and Arkansas are human-induced. The article talks about the oil industry’s impact on the increased risk of earthquakes in the area, and this impact is mostly caused by hydraulic fracturing (fracking) and horizontal drilling. Gilman shows that there ...

- Explain the significance of the grand challenge that you consider in this assignment. System thinking engulfs the criterion of problem solving that concentrates on the larger picture of all the responsible aspects, as opposed to objective approaches which focus on those agents that are directly linked to the problem only. Taking the challenge of global warming and climate change, this problem solving approach can be demonstrated effectively. What makes it so pronounced is the threat it poses to a large portion of the earth and generations to come. New York City, Norfolk, Va., Venice, Bangladesh, Indonesia, the Philippines, ...

Introduction

Freezing temperatures during winter months greatly contributes to hazardous conditions on American roadways. According to the Salt Institute (2012) 70% of roadways in the United States experience congestion due to winter weather. Icy roadways greatly contribute to hazardous winter conditions and can increase the chances of personal injury or accidental death for motorists. Currently, across the nation, icy roadways are addressed with the application of sodium chloride (salt) to deice icy roadways and to prevent the formation of ice on dry roadways.

The mechanism by which salt causes ice to melt and prevents ice from forming has been ...

Visiting The Trans Alaska Oil Pipeline

The construction of Alaska pipeline was completed in the year 1977 by APSC (Alyeska Pipeline Service Co.) at an expenditure of about 8 billion USD within two years. This was the leading privately funded construction project effort within that error. The TAPS (Trans Alaska Pipeline System) was constructed as a way of transporting rudimentary oil from Prudhoe Bay oilfields situated in North Slope of Alaska to the northern most and marine ice-free port within Valdez, from where tankers were used to transport the crude oil to U.S refineries. At the peak of building the pipeline, the construction company as well ...

The main purpose of this research paper is to discuss whether there is any proof and evidence of global climate change, as the debates about this question have been conducted until nowadays. First, it should be mentioned here that any climate change is a long-lasting considerable change in any statistical form of weather pattern`s distribution for different time periods that can vary from years and decades to thousands and millions of years. For example, it can be a change in weather conditions, or distribution of them per average conditions. It`s usually caused by different factors of biotic origin like ...

Lipids insolubility in water is general. Lipids structure has great number of variety. There are two types of fatty acids naturally, may be saturated or unsaturated. Unsaturated acids have lesser melting point than saturated ones.

Introduction

Selection of materials is an important part of engineering design. Material selection is aimed at increasing the performance as well as the life of the engineering component and hence, very important for success of engineering component. The nature of loading, expected life, working environment amongst other factors determines the material to be selected for a particular application.

Therefore, engineers and designers must determine the properties of materials before they incorporate them in their design. Mechanical properties of materials such as ultimate tensile strength, Modulus of Elasticity, proof stress, specific strength, toughness and density amongst others are some of the important ...
