Chapter 3 Atoms and the Periodic Table

For centuries, many have tried to learn about the smallest particle. As far as 2500 years ago, Democritus and Leucippus created an idea for the atom and called it ‘atmos’ meaning indivisible. Various philosophers and scientists have proposed models for what and how the atom should be. The initial theory proposed by Dalton in 1803 states that atoms are indivisible and that all atoms of a particular material are identical. He also stated that atoms of different materials join to form compounds. J.J. Thompson proposed the initial model of the atom. It is called the plum pudding model. He Continue reading...

Introduction

Closed-Circuit Television, initialed as CCTV can be said to be the application of video cameras in the broadcasting occurrences within a certain place. Worth noting herein is the fact that CCTV is different from the broadcast television in that; the signal is was openly transmitted through the use of point to point multipoint or wireless link. They trace their conception back to the 1940s in Germany where the military were using them to monitor their rocket launch (Matchett, 2003). The United States as well are on record to have used CCTV during the development and testing of the atomic Continue reading...

Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Continue reading...

UN POSITION ON NUCLEAR WEAPONS

There are more than two dozen countries of the world that have nuclear power, however, only a few have nuclear weapons and few are suspected of making nuclear weapons. During the cold war era between US and USSR, nuclear arms race was the most alarming feature as both the super powers rapidly built up their stockpiles of nuclear weapons. Later when both realized, there would be devastation caused by nuclear weapons, they embarked upon a number of agreements for reduction in the number of nuclear weapons. Efforts were speeded up after disintegration of the USSR; however, the issues remained Continue reading...

One of the central questions of philosophy has always been a debate as to whether or not humans are free to make their own choices, or whether or not the causality of the external world affects are ability to make choices. This question is important because it underlies the centrality of what it means to be human and how culture is constructed. If freedom to make choices exists, then institutions such as prisons are just, because they punish on the basis of the assumption that someone who has committed a crime was acting freely and of his own violation. Continue reading...

Today, one of the global issues people face to is different types of pollution. With human development, pollution is becoming worse, and as a result, other issues appear. Among them are global warming, new diseases, deforestation and many others. But, it was not like this all the time, as at the beginning the level of pollution was not so high. Otherwise, it would have been an apocalypse already. That was the industry development that caused global pollution.
Even in the late 13th century, people knew about air pollution. For instance, King of England Edward I punished every Londoner, who Continue reading...

Methods of Heat Transfer

Conduction
The first method through which heat is transferred from one object to another is conduction. Conduction occurs in liquids and solids through transfer of kinetic energy present in one particle to the immediate particle(s) in its surrounding. By considering the bonds existing between atoms and molecules in solids as elastic links, the vibration of one particle due to increase energy level caused by heat, the next in its line vibrate too. This process is replicated in adjacent particles thereby allowing transfer of thermal energy from a body with a higher temperature as compared to the one with Continue reading...

Godzilla is the monstrous dinosaur awakened from his deep slumber in the depths of the sea and started raising havoc in Tokyo, Japan. Godzilla is a movie set during 1954 with a baggage of controversies, issues, appreciations and critics. Godzilla is more than just the rubber monster destroying toy trains and buildings. He is more than the flames he breathes to the human population in the film He is more than just mutated dinosaur. Godzilla is a symbol of fear for something bigger. He is a shadow of the nuclear weapons.

Introduction

Initially there were beliefs that, MMPs are jointly able to degenerate all constituents making up the extracellular matrix (ECM) together with basement membrane that confines their operations to tissue reconstruction as well as the preservation. Nonetheless, the contemporary studies also signify that MMP-1 is responsible for controlling the production or else the activation of the chemokines. At this point, it is critical to understand that MMP-1 is among other MMPs.
Similarly, the knowledge holds it that MMP- 1 cleaves a peptide bond beforehand a residue comprising of a hydrophobic adjacent chain, for instance Met and Leu. The other sideways Continue reading...

Due to the complex landscape of the Navajo Nation, a lot of potential economically relevant sites, both for tourism, mining, and even agricultural purposes have been identified. Natural sights such as the Ship Rock Continue reading...

U.S. History

The reason why the United States entered the First World War is justifiable. At first, the United States had pledged to be neutral; however, it later changed its stand when German mines destroyed and sunk several American ships that were travelling to Britain. The tension between Germany and the United States arose over Germany’s segregation of the Isles of Britain. Britain was one of the closest trading partners of the United States. In 1915, the Germans declared an unhampered warfare against all vessels and ships, whether neutral or not, that entered the war zones around Britain. Continue reading...

Essay Examination

Living things have distinct characteristics that differentiate them from non-living things. They respond to variations in environmental conditions for instance decrease or increase in temperature. A living thing is able to detect the changes in the environment and react in a manner that can help it maintain the normal external and internal conditions. For example, most living animals move away from high temperatures. Plants too, respond to the saline environment by excluding sodium and chloride ions. Living things also respire. As a result they take in oxygen and gives out carbon dioxides. Moreover, living things acquire nutrients and energy Continue reading...

Atomic force microscopy (AFM): used for imaging, visualizing, taking measures and manipulating objects in nanometer scale. The device has a mechanical probe that senses the material placed on its surface (John 1).
Scanning Tunneling Microscope (STM): the STM is used to perform atomic level imaging of surfaces. Its lateral resolution is about 0.1 nanometers while its depth resolution is around 0.01 nanometers. This measure suffices in manipulating an image that is good enough (John 1).
Nanoimpellers: Tubes made from light-sensitive silica. They are used to carry cancer-killing medication and target only cancer cells. These nanoimpellers are injected Continue reading...

Question 1)

According to Ede and Cormack, what was the impact of Napoleon's reign on the development of scientific and technical training in France?
Napoleon's reign included a refocusing to the education of the masses, including educating women. He centralized and standardized the education system with a focus on language. Napoleon believed in women’s education, to a point. He permitted the reestablishment of the Catholic elementary schools that educated boys and girls. Napoleon’s priority was secondary education however. In this area, he saw to standards not only for students but also for teachers and the curriculum. This was in Continue reading...

Introduction

The atmosphere by delineation refers to the gaseous composition together with other particles that surround the surface of the earth. In the atmosphere, there are gases, and the solid particles that are in suspension. Scientifically, the atmosphere is divided into four major layers. Using the ascending order, the first layer is the troposphere that rises about 10-13 km from the surface of the earth. This is closely followed by the stratosphere that rises over 50km above, them the thermosphere that rises between 80-480 km, and lastly the exosphere that goes beyond the 480 km and gradually dissipates in the Continue reading...

The adrenalin molecular structure has a more stable structure more than both Mephedrone and Nephyrone. The adrenalin structure has an extra OH molecule that makes it distinguishable from the Mephedrone and Nephyrone. Several analytical tests can be used to determine this difference.
There are various chromatographic techniques that can be used to test the purity of the adrenalin tablet. The first method is paper chromatography. This chromatographic method is used to analyze chemicals that Continue reading...

Question 1

John Adam’s opera Dr. Atomic is about the history of Robert Oppenheimer and others who participated in the famous 1940’s Manhattan project, to create the atomic bomb. Dr. Atomic is set in Los Amos in New Mexico hours before the test-firing of the first atomic bomb. Postmodernism is the movement in literature, visual arts, music and drama which rejected the Victorian standards of how art should be made, consumed and meant (Heartney 1). Dr. Atomic has different aspects of opera that have differed from the Victorian standards making it postmodern. A key characteristic of postmodernism is that Continue reading...

The Class Name

The 26th of April this year will be marked as the twenty-eighth anniversary of a disaster of a worldwide scale. So much time has passed after it and we still remember that fear of a nightmare of such a nuclear disaster that has changed millions of lives during a couple of days and it changed the nature itself, as well. The topic of our research is the Chernobyl Catastrophe (or “Chernobylska Katastropha” in Ukrainian); we`re going to describe its causes and consequences, the governmental meanings about it and how it changed the territory of Ukraine and the countries Continue reading...

Weapons of mass destruction

The dangers that weapons of mass destruction present have been at the center of international politics since nuclear bombs were dropped over Japan, which automatically signified the end of The Second World War, and the beginning of The Cold War. The term “weapon of mass destruction” (WMD) determines the whole variety of weapons that have their large scale destruction potential, and the murder of great number of civilians as their main features. There are three major sorts of weapons of mass destruction: atomic weapons, chemical weapons, biological weapons. Every type of these specific weapons possesses the potential for horrible Continue reading...

The Mayan apocalyptic predictions of 2012 have long since passed, and civilization has essentially moved on from its portents of doom and gloom. However, with Gregg Braden’s Fractal Time: The Secret of 2012 and a New World Age, elements of self-help spiritualism and pseudo-math are combined to create a work of New Age spiritualism that, while certainly illuminating to the converted, will not successfully convince those looking for philosophies to the universe that require greater rigor. Looking at the book through an air of skepticism, Fractal Time fails to convince, poorly using its own research and loosely connecting Continue reading...

Version control systems

Introduction
There are different version control systems which have been developed to be used in managing software development projects. The choice of the version control will depend on the model and the workflow of the projects and the nature of organizational workflow that is supported. It is important to understand the requirements of the organization which will use the version control. This will determine the way the version control will suit and align with the goals of the developers. Before a choice is made, it is important to have clear view of the requirements of the organization. This paper Continue reading...

Abstract

Ozone layer depletion is a phenomenon in which ozone layer in the stratosphere thins out making it possible for the direct penetration of UV rays into the Earth's surface. This can lead to an array of harmful effects on human health, plants, and animals and can even trigger climate change. Chlorofluorocarbons are recognized as the primary cause accounting for 80% of ozone depletion. Though a lot of steps have been taken around the world to reduce ozone depletion, it may take about few decades more to completely heal the ozone layer due to the long standing stability of CFCs Continue reading...

Father John Siemes was a Jesuit priest who was living in the Novitiate of the Society of Jesus at Nagatsuka, Japan during the bombing of Hiroshima on August 6, 1943. Amidst the destruction and confusion that the detonation caused the Hiroshima populace, the detonation did not greatly affect a community of Jesuit fathers in a nearby parish. Practically, all the present members in the community, among them Fr. John Siemes, were unscathed. The building that housed the community remained upright despite the fact that the shelling destroyed all the buildings within the vicinity of the city.
Fr. Siemes who Continue reading...

It is important to comprehend the reason why Hiroshima was a likely target. According to Hersey (107), “the ruined city had flourished and had been an inviting target mainly because it had been one of the most important military- command and communications centres in Japan, and would have become the Imperial headquarters had the islands been invaded and Tokyo been captured.” In other words, how had the dropping of the bomb changed the lives of the survivors? Was the decision by the United States government to hit Hiroshima with the atomic bomb necessary? Should the Japanese have been forewarned Continue reading...

The importance of the resurrection story to St Paul

Apostle Paul is considered the author of more than a half of the New Testament books. Nowadays, theologians continue studying his epistles, trying to resolve issues and find answers to many questions concerning Christian views on the world. Some of Paul’s epistles reveal the topic of resurrection of the dead and the life after death. We find reflections on these issues in Paul's epistles to Corinthians, Thessalonians, Philippians and Romans.
- What motivated Paul to develop the theme of resurrection?
The book of Acts contains the story of the Apostle Paul’s preaching in the Areopagus - preaching Continue reading...

- Introduction
Radiations such as  - rays, UV rays, etc. have ionizing effects on tissues and have the ability kill cells and inactivate viruses. A detailed analysis of the survival of such cells and viruses are imperative in many fields, including radiation oncology, public health and environmental photobiology. However, the mathematical and statistical tools based on target theory in radiobiology are mentioned in literature (Alpen, 1988, Smith, 1989, Hall, 2000) and are wide in use in the analysis of experimental data involving biophysical mechanisms of the repair of radiation damage. This work demonstrates the use of probabilistic approaches in descriptions Continue reading...

Introduction

Atoms have become an important study item not only in the scientific field, but also in the overall study field. Atoms have a basic meaning as being a unit of any chemical element. This is only but a basic understanding of what an atom is. Atoms have a history from which it got its basic definition dating back to the Greek period. Early Greek ideas about atoms were diverse based on what the perception and mentality was. The understanding of atoms in the ancient Greek empire was more of a philosophical than scientific. The basic thought during the ancient Continue reading...

Richard B. Frank’s essay “Assessing Realities” is written to shed a light of perspective into the issue of what line of thinking went into the decision of Truman and his military advisor’s to use atomic weapons on Japanese cities at the end of World War II, and whether or not this was the ethical line of decision making for them to have made. As the author points out, American’s perceptions of the rightness of this decision has changed significantly since the time of the action, when far fewer Americans supporting this action decades after Hiroshima and Continue reading...

The Savannah Campaign

According to Civil War Historian Anne J. Bailey, the Savannah Campaign was “the most destructive campaign against a civilian population during the Civil War (1861-65)” and is significant because it incorporated psychological warfare (2002). The campaign began in November of 1864 and lasted a little over a month. In this campaign, General William Sherman of the Union Army took his troops across Georgia to the Atlantic Ocean (Bailey 2002). By the time Sherman began his “March to the Sea” as the Savannah Campaign is often called, the Confederate Army of Tennessee had moved to Alabama. This left Georgia unprotected. Continue reading...

The argument presented in the “Petition to the president of the United States” is quite successfully crafted and factual. Given the extensive destructive nature and long-term effects of atomic bombs, the president should have practiced extreme restraint in authorizing the usage of atomic bombs. Why would someone use a weapon whose radiation effects are bound to genetically affect successive generations of any survivors? What authority would someone have as to deliberately taint the genes of an entire generation? It is plain inhumane to use atomic bombs on any animal or plant let alone a human being. Scores should always Continue reading...

Explosives are a rather young industry. Despite the stereotype of it being primarily used for military purposes, it has come to be applied in a variety of fields. It stand to reason that explosives have given belligerent parties a strategic advantage on the battlefield, yet their application is well documented in areas other than the military industrial complex. It is quite difficult to envision the peaceful demolition of decrepit structures that are up for destruction due to the degrading state of the framework. The extractive industry is dependent on explosives inasmuch as mineworkers need their way cleared or portions Continue reading...

Introduction

Freedman’s commentary of nuclear deterrence being, C’est magnifique, mais ce n’est pas la stratégie or ‘It is magnificent, but it is not strategy’ in English, may have been coined from the famous remark of French Marshal Pierre Bosquet while watching the British light cavalry wipe itself out in The Charge of the Light Brigade at Balaclava in the Crimean War of 1854 in which he exclaimed, “C'est Magnifique, Mais Ce N'est Pas La Guerre” or ‘It is magnificent, but it is not war’. In a similar note, Freedman is implying that the possession of nuclear Continue reading...
