A dental cavity in a tooth is the result of the decay process that happens over time when bacteria in the mouth produce acids. In a time, acids can dissolve enamel and cause a hole, which is known as a cavity. Unlike some other injuries, a cavity will not heal by itself and needs to be filled. Several different materials are available, and each material has advantages and disadvantages.
Dental fillings can be categorized as direct or indirect restorations. Direct restorations are fillings that get inserted into a cavity in a single visit. These substances include consisting of amalgams, glass and resin ionomers and composite ...

Introduction

Emission of the toxic substance by industries is common all over the world. Toxic substances are emitted daily by industries and anthropogenic activities.

Executive Summary

The results of the recent studies among U.S. pregnant women prove that fish consumption during pregnancy benefits the cognition of the offspring in infancy but at the same time, high levels of mercury that fish contain have adverse effects on the cognition of little children. So, it is recommended to pregnant women to look for the fish species with a low level of mercury.
The issue whether pregnant women harm their babies or on the contrary benefit the child’s brain development while consuming fish is ambiguous. There has been a great quantity of researchers who have been studying ...

Introduction

Autism, Aspergers’s syndrome, and pervasive development disorders are conditions which affect children during their early childhood (Scahill & Bearss, 2009). These disorders are characterized by deficits in socialization and communication as well as unusual interests and repetitive behaviours (Scahill & Bearss, 2009). The aetiology of the diseases is yet to be fully elucidated and is the subject of myths, conjecture, and wide ranging debate. A debate about a possible link between autism and vaccines in a prime-time TV show and government settlements under the vaccine protection program are some of the recent events in relation to the issue (Scahill & Bearss, 2009). This ...

Introduction

Panter-Brake (202) asserts that most people use beauty products with the assumption that these products have undergone thorough testing to ensure their safety before they reach the consumers. The assumption comes because the government is known to regulate most consumer products such as food, water, among others. Therefore, people expect that FDA ensures the health and safety in the cosmetic industry so as to protect consumers. Unfortunately, little power has been given to FDA in regulating cosmetics’ ingredients. The people who govern cosmetic industry are responsible for ensuring safety of the beauty products. Several studies reveal that consumer safety ...

The National Aeronautics and Space Administration (NASA)

Prior to the first space missions that enabled the world to see beyond the planet, the public had many misconceptions over what is out there in the universe. There were a few mentions of space people that are bent in destroying mankind or even technologies that could only be seen in the future. Some also speculated that there is a different kind of world out there that is waiting to be discovered, and there were also a few who believed that once man sees the world outside Earth, a lot of unanswered questions would be brought to light such as the beginning of ...

Methods of Engagement in Afghanistan: Security, Identity and Economy

The cultural differences between the United States (U.S) and Afghanistan are huge. The U.S. celebrated its independence from the British Empire about 1236 years ago compared to Afghanistan’s population who has lived there for generations. The U.S. first became involved militarily there when it armed Afghan fighters against the Soviet invasion between 1979 and 1989. A devastating ten year Civil War followed. (Rohde & Crossette, 2001) Next the Taliban came to power and then lost power when the current U.S. war against Afghanistan started in 2001. Unfortunately after over a decade war in Afghanistan the suffering of the people seems ...

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 ...

Arguably, the global pollution is tremendously in the rise. Many people visit the coastal region of Southern California Beach; hence, pollution is increasingly threatening the waters, which individuals play, and swim exposing them to the risk of illness. Studies show that approximately three beaches in Southern California were ranked the most dirtiest beaches in the nation, these included L.A County’s Avalon, Doheny Beach, and Cabrillo Beach. Undeniably, beach vocations form an annual event among many people and families in the United States. As a matter of fact, beachgoers at most polluted beaches in Southern California bring back a lot of ...

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 ...

Introduction
The vaccine-autism controversy came into limelight in 1998 after a UK-based gastroenterologist Dr. Andrew Wakefield published a paper linking the MMR vaccine to autism using inappropriate and false research techniques (Gerber & Offit, 2009). The theory was later disproved. Yet, some parents still felt that the reason for their child having autism was vaccine. This is primarily because the human mind is inclined towards reasoning, questioning and pattern perception. As Chabris and Simons point out in their book, this very drive for stamping on reasons for every occurrence and coincidence leads to the Illusion of cause theory (2010). According to ...

Externality is a situation in which the activity of one entity affects the welfare of another entity in a way that is outside the existing market (Rosen, 2005, p. 47). Simply put, externalities are the costs or benefits that arise from market transactions which are not reflected in prices. And when we speak of negative externalities, obviously, these are costs to third parties (other than the producer and consumer). Why is there negative externality? I learnt from Economics that under a competitive system, the market price of a good takes into account both the negative and positive effects of using the good. However, ...

The word “slavery” evokes many emotions: shame, anger, empathy, and pride. We have come a long way from slavery; imagine what slaves would think if they found out that America is ruled by a Negro president. They would produce a new Negro spiritual song that no one has ever heard. In that song they would sing about the cruelty, they endured and at the end of the song they would sing with great gusto, Free at last! Free at last!

Slaves faced unusual hunger every day of their lives. They were underfed, and even if they were given adequate food while they ...

Gold (chemical symbol Au and atomic number 79) is a shiny, dense, soft, ductile and malleable metal. In its pure state, gold is bright yellow in color with a luster considered traditionally and to date as attractive. It is an element of group 11of the periodic table under the transitional metals. Gold is among the least reactive chemical elements and does not oxidize in water or air. It therefore occurs as a free element in most cases in forms of grains or nuggets in rocks, in alluvial deposits, and in veins. Gold also occurs, though rarely, as gold compound e.g. with tellurium. ...

A moon can be defined as a natural satellite that rotates all round the planets. Moons usually vary in their sizes with every planet being bigger than its moon. However, there are several moons which are bigger than Pluto planet and only two moons that are larger than Mercury. Mercury and Venus don’t have any moons while the earth has just one moon (Space Today Online). The earth’s moon is one of the largest natural satellites with 2,160 miles diameter. This moon is much closer to the earth than the rest and can be seen through the ...

1. Balance Diet and Physical Activity against Obesity and Hypertension
The most essential way to prevent hypertension for those who are prone to obesity, and certainly for obese people - is the fight against excess weight. When we reduce the body mass by 1 kilogram - blood pressure decreases by 1 millimeter of mercury regardless of the original pressure level.
There are only two ways to lose weight: a diet regime and an increased physical activity. But it is important to immediately warn against fasting that is very dangerous for health. It is possible only under the supervision of ...

Electronic devices may be deemed the crowning achievement of decades-long scientific efforts in their own right, signifying the human quest for ultimate comfort.

Contemporary computing systems such as HPC (High Performance Computing Clusters) and Data centers face the challenge of high cooling and power costs. Gupta, Mukherjee & Banerjee (2011) state that the high consumption of power is a concern because it impacts on the cost, environment, reliability and scalability of the computing systems. ...

There are a small number of extremely significant archaeological discoveries that were made by chance without scientists’ intentional efforts and search. Among such exceptional finding are the Rosetta Stone, the Dead Sea Scrolls, and the Terracotta Army, which is situated in the Mausoleum of the First Qin Emperor Qinshihuang. The significance of the latter has been recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1987 by way of being inscribed in the World Heritage List as one of the World Heritage Sites to be specifically preserved and safeguarded by the Chinese government, a home for the Mausoleum (" ...

Abstract
Today, the United States has over 5600 offshore gas and oil platforms; there are also over 27,000 miles of pipeline in the Gulf of Mexico area alone. This shows the extent to which offshore oil drilling occurs in the United States. In other developed parts of the world, the situation is the same. Oil is a product on high demand; this facilitates efforts in extracting it form its deposits deep in the sea floor. The retrieval requires the use of sophisticated equipment ...

Volcanism refers to the eruption of magma or molten rock, or hot water and steam, including volcanoes, pyroclastic fragments, geysers, as well as fumaroles on top of the surface of a planet (Encyclopedia Britannica 1). A volcano refers to the vent through which gases and magma are discharged. When a planet loses its internal heat it results to volcanism. When a rock that is close to the surface becomes hot sufficiently enough to melt, it results to a volcano being formed.
On the Earth, volcanism often occurs in association with plate boundaries. Where two plates move apart, for instance at mid-ocean volcanic ...

Visions as Aliens?

There are two similar descriptions in the Bible of men that appear as visions in the Old Testament to Daniel (Standard King James Version, Daniel 10:5) and in the New Testament to John (Rev. 1:13-16). Although there is much religious scholarly debate as to whether these visions are of Jesus or merely an angel, it remains that the description of these men are highly similar to each other and contain very specific details that provide many points of reference. These descriptions can be used in the current time in an attempt to interpret what might have actually happened, in ...

The Historical Causes of the US Lunar Projects

The United States and the Soviet Unions at this period in history were the world Super Powers. The two countries were engaged in the Cold War trying to dominate each other. There were three events that occurred that caused the United States to launch into lunar projects. In the year 157, the Soviet Union launched the Sputnik 1 which was the first artificial satellite in the outer space. The launch of the satellite caused quite uproar in the United States as it felt that the Soviet Union was advancing in technology at a higher speed (Spudis, 2010). The event was ...
