The Egyptian kings and queens were buried, in the Deir- el bahri located in the west bank of the Nile. Among the pharaohs were a few mummies, which could not be identified and was aside letter of the alphabets to them. The coffin in which unknown man E was buried into was examined once he was removed. The coffin appeared to have wood shaving inside, which in tells that coffin was enlarge to accommodate the body of unknown man E. This discovery clearly shows that this coffin was not intended…

the esophagus. One will hope to stay away from a more complex problem: GERD or gastro esophageal reflux disease (1). Bases can be extremely important to one’s health and wellness. Common bases include sodium hydroxide, sodium bicarbonate, sodium carbonate, and ammonia. They usually have a bitter taste and a slick feel. They can be used for a variety of things: NaHCO3 is an ingredient in baking soda. Not only are they used for food and health benefits, but bases are also used for manufacturing,…

It’s the largest…

Carbon dioxide (CO2) is the most important greenhouse gas, contributing to 60% of the enhanced greenhouse effect. The atmosphere now contains more carbon that at any other time in the last 2 million years. Each sink of the carbon cycle will change as this carbon makes its way through the cycle. The global warming caused by greenhouse gas emissions also accelerates the rate at which carbon is released. Permafrost contains rich deposits of carbon and large amounts are released as a result of their…

of ingredients and the 5th item listed is “Cocoa processed with Alkali”(Cocoa Puffs). Alkali is a chemical compound that neutralizes or effervesces with acids and turns litmus blue. This in other words this means Cocoa is “washed in a potassium carbonate solution that neutralizes the cocoa’s acidity to 7”(Velie). What the Velie means by having the acidity to 7, the acidity is based off the ph scale 1-6 being an acidic item 8-14 being alkalis and 7 being neutral. Based off of this we can see…

the body to release hormones and enzymes that affect virtually every component of the body. Therefore, calcium supplements are most effective taken with ith food. According to the National Institute of Health (NIH), there are two forms of calcium carbonate and citrate. According to the author Taylor Wallace professor in the Department of Nutrition and Food Studies at George Mason University, the body can only absorb roughly 500-600 mg of calcium at one time. (qtd. in…

Starfish are classified under the domain Eukarya. Their multicellular presence and existing nuclei exclude them from prokaryotic domains. Furthermore, they are classified in the Animalia kingdom because they are not prokaryotes or protists. Next, Sea Stars fall under echinoderms, which are invertebrates characterized by their hard, spiny skin. The echinoderm phylum consists of mostly sea creatures (Pawson & Miller, 2016). Organisms placed in the Asteroidea class are identified by their arms that…

Cavities Many question come to mind when you hear the word cavity. Many may ask: How do I get a cavity? How long does it take for a cavity to form? How did I get this cavity?. But first what is a cavity? A cavity is formed when your tooth starts to fall apart and break down. Once you get a cavity there is no turning back. A cavity in fact can even progress and get worse. A cavity is formed when the bacteria such as plaque sits on your tooth for a period of time. What is plaque? Plaque is a…

2-deoxyguanosine as well as some of their ribosyl O-protected derivatives, to the corresponding bis-N-Boc carbamates S.37 (Sikehi et al., 2006). For guanosine compounds, the carbonyl group of the base moiety was also protected as its O-Boc enol carbonate (Figure X.X.X). Transient in situ O-silylation facilitated the preparation of bis-N-Boc nucleosides from unprotected sugars. This strategy allows the protection of nucleosides with a base-stable and acid-labile group suitable for the preparation…

INTRODUCTION Background The macrocyclic organic molecules Phthalocyanines (1) which are comparable to the naturally occurring porphyrin (2) ring systems shown in (Figure 1). The porphyrin molecule consists up of four pyrrole subunits which are associated in n-conjugation by methine carbons. 1 2 Figure 1: structures of phthalocyanine and porphyrins molcule The compound…
