Magnesium oxide

Valuable, colorful, and enriched with a unique history are three phrases that describe many things. However, all three combined only seem to describe birthstones. Birthstones are amazing objects that affect our economy in many ways. More importantly, birthstones have a deep connection to chemistry and science. Birthstones can also be used for medicinal purposes and healing techniques that have helped humans throughout time. Overall, birthstones contain many disciplines and the concept is one of…

unable to provide for Robert’s education or home necessities. During his time at the Massachusetts Institute of Technology, Robert chose to do his dissertation on the concept of measuring the presence of electrons at the surface of quartz and magnesium oxide. (Dalakov,…

Beta blockers are the first line drug choice when treating angina related to CAD. Beta blockers decrease cardiac oxygen demand, by blocking beta receptors in the heart, decreasing heart rate and contractibility, reducing peripheral resistance and after load. Slowing heart rate increases diastolic fill time, increasing the amount of time blood flows throughout myocardial vessels. When taken with nitroglycerin, extra benefits include blunting reflex tachycardia. Dosage starts out low and slowly…

List three differential diagnoses for epigastric pain in adults. Include rationale, diagnostic testing, and treatment. Epigastric is the pain that comes on the upper middle portion of the abdomen. It this can occur due to several conditions i.e. irritable bowel syndrome, peptic ulcer, and pancreatitis, and as a referred pain of myocardial infarction among other minors ones. Diagnosis and treatment Peptic ulcer disease Peptic…

system 3.1.1 Optimization of superplasticizer M-S-H binder contains high content of very fine silica fume particles and therefore requires much higher water demand than Portland cement (PC) for workability (Zhang et al (2009)). Also, the reactive magnesium oxide particles were found to have cells lattice structure and therefore require higher water demand than PC (Eubank, 1951). For those reasons, tests with superplasticizers using the procedure as described in (2.2) were performed to select the…

(Kte’pi:2014) Earth completes a spin in 24 hours while Mars takes 24 hours 39 minutes and 2 seconds. Earth and Mars both contain similar elements however in different size quantities. Both Planets consist of silicon(Si), oxygen(O), Iron(Fe), Magnesium(Mg) Aluminium (Al), Calcium (Ca) and Potassium(K) and these elements create rocky planets with crusts of basalt, feldspar and glass. (Kte’pi:2014). However similar in composition on the surface, it is the activity below the surface that…

The United Nations has projected that by 2050 the world population will reach approximately 9 billion (Food and Agriculture Organization, 2009, para. 2). As population increases, so does the demand for food resources. Since only a small percentage of the world population is vegetarians, animal proteins remain an important source for fulfilling basic nutritional needs. In addition to increasing population growth, Van Huis (2012) states that the recent economic bubble in developing countries in…

This is a delicate balance of carbon dioxide, nitrous oxide, methane, and fluorinated gases. An increase in GHGs can cause an increase in the planets temperature. Image 1.3 shows the ratio of the 4 gases in 2013 (Inventory of U.S. Greenhouse Gas Emissions and Sinks, 2015). This is relevant to landfills and…

Aquatic environments and how they differ in chemical nature due to the effects if global warming Introduction The term ‘Global Warming’ refers to the process in which the Earth’s average, global temperature increases due to numerous trace gases in the atmosphere, which have the power to absorb part of Earth’s outgoing infrared radiation. The concentrations of these gases have been increasing due to human activities, such as the burning of fossil fuels, since the Industrial Revolution. The…
