Convention for the Prevention of Pollution from Ships (MARPOL).” (3) MARPOL, the International Convention for the Prevention of Pollution from Ships, is concerned with preventing marine pollution from ships (4). The law establish limits on nitrogen oxides (NOx) emissions and require the use of fuel with lower sulphur content, in order to protect people’s health and the environment especially the water. “The requirements apply to vessels operating in U.S. waters as well as ships operating within…

Boreal, Coniferous, and Deciduous Forests Boreal, deciduous, and coniferous forests each possess distinctive traits and soil characteristics. Forests soils give important contributions in nitrogen and phosphorus transformations. These transformations are dependable on the weather conditions of the forest and the type of vegetation it contains. Soil mineralogy and organic matter also play an important role in the nitrogen and phosphorus transformations on the forest floor. Boreal forests are…

Arsenic contamination and possible remediation Victoria Reyes Texas A&M International University Abstract Arsenic can be found in many places on Earth. This includes from natural sources and as a by-product from different anthropogenic activities. The fact that arsenic can be found so commonly on Earth has lead to the contamination of several countries’ drinking water. This has put many people at risk for arsenic poisoning. There are many complications that come from the continuous ingestion…

Greenhouse gases are the root of the problem when it comes to the problems in our environment. According to EPA. gov, “gases that trap heat into the atmosphere, are called greenhouse gases. These gases consist of Carbon Dioxide, Methane, Nitrous Oxide, and Fluorinated gases such as Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and many more”(Epa.gov). These gases are most likely caused by factories,various ways of pollution, and human activity. The first time that I had heard about…

Titanium bones are the implants that doctors use when a bone is broken to badly to heal naturally. The natural way for a bone to heal is in a cast and take time for the bone to heal but titanium implants help the bones that can not do that. Titanium is used in the body because it is lightweight, sturdy and it would last long because it is durable. Titanium bones have been worn away with time especially at the hip and elbow joints but scientist are working on a way for titanium bones to become a…

conditions needed. These conditions are climate, pressure, and heat (3). All birthstones form in different climates. For example, the peridot (see figure 2) is a volcanic birthstone and usually forms near ground shaped by volcanoes where magnesium and iron are present. On the other hand, an opal (see figure 3) usually forms in humid climates near the ocean. Scientists collectively learned from another’s notes on the subject to find out and recognize the climate each Birthstone needs to form.…

Factory farming needs to be more closely monitored because it is a leading cause of animal abuse. The definition of animal abuse is:“The intentional infliction by humans of suffering or harm upon any non-human animal, regardless of whether the act is against the law” (UIA). On factory farms, animals are confined to battery cages, gestation crates, farrowing crates, feedlots and veal crates for the majority of their lives. These forms of containment cause severe pain and disease to the animals.…

Cause and Effect of Water Pollution in India Rajdeep Kaur Environmental Science 101 Professor Mark Ditter October 8, 2014 Abstract Water is one of the natural resources that human beings are polluting. Water pollution has become a huge problem in many countries today. Due to water pollution many new diseases have been developed over time which have affected the humans at a very high rate. India is one of the countries that has the most polluted water bodies compared to other countries. There…

He experimented with pieces of iron and discovered that the resistance increases when the current is in the same direction as the magnetic force and decreases when the current is at 90° to the magnetic force [1]. With the growing demands for higher HDD storage density, other forms of…
