Overall, my nutrition plan was based on 1800 calories. It seemed to be that I am not eating enough everyday. My calorie intake came out to be 1113. This report showed that almost all of my calorie levels are lower than the dietary guidelines. This could be due to the fact that I am not a fan of most of the food the cafeteria serves at the college. I feel that when I am home my calorie intake would increase. Most of the calories I intake are coming from carbohydrates and saturated fat. For…

Hydroponics, which is a way to grow plants with mineral nutrient solutions found in water without soil, will be used. Europa is composed of mostly water. The water will need to be filtered by using Dean Kamen’s “Slingshot Water Purifier” to make it drinkable. Fertile soil will not be produced. However, plants still need the minerals found in soil. Hydroponics is the solution to this problem. Composting is the breakdown of organic materials into rich minerals, such as nitrogen, phosphorus, and…

some pathogens and small particles find their way to pollute groundwater. Purification of seawater is an expensive process and might not be available to poor economy countries. Lakes, rivers and oceans are at constant risk by heavy metals, poisonous minerals from industry and chemical fertilizers. Therefore, providing clean fresh water for the whole population is a responsibility that we really must take under consideration. There are several processes done to purify and provide water. First…

because they are held more strongly together by dipole-dipole--and in these molecules case--hydrogen bonds. Liquids that are hydrocarbons can also be more viscous because they have longer carbon chains. For example, hexane has much less carbons than mineral oil and is therefor much less viscous. It seems that intermolecular bonds in hydrocarbons become stronger as the number of carbons in the chain increases. Additionally, C-H series seem to have weaker bonds than C-OH series. This is because…

beverages and sports drinks account for sales of more than $18 billion a year in the United States alone. Throughout the past year there has been an addition of vitamin content in many vitamin drinks. Companies are increasingly adding vitamins and minerals to vitamin drinks. This addition of vitamins can be beneficial to people facing vitamin deficiency and people who just don’t have the time to get their vitamins in their system throughout the day. Although many believe that vitamin drinks…

In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

Inuit, Native American nomads of the frozen north Inuit are a people that live in the frozen artic and sub artic lands of north America, like Canada and Alaska they even live in other parts of the world like Siberia and Greenland. They are one of the hundreds of tribes that live in North America today. Between the United States and Canada there are over a thousand tribes that call these lands home. Throughout history the Native American all across the continent of North America developed and…

Historians attribute many reasons for the fall of Mesopotamian Empire. Some say that there was overcrowding which subsequently led to pollution along with other reasons like war and irrigation system problems. Mesopotamian cities also had major pollution problems. Lack of indoor toilets and ineffective garbage collection led to contaminated water supplies and frequent epidemics such as Typhus. Another factor that led to the end of the Mesopotamian civilization was warfare. Mesopotamia was badly…
