USING COMPUTER SIMULATION MODELING TO REDUCE WAITING TIMES IN EMERGENCY DEPARTMENTS Igor Georgievskiy‚ Alcorn State University Zhanna Georgievskaya‚ Alcorn State University William Pinney‚ Alcorn State University ABSTRACT This paper examines the wide-spread problem of extended waiting times for health services‚ in the context of the Emergency Department (ED) at a regional hospital. In the first phase of the study‚ a field observation was conducted to document the current operation of the ED. The

Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide. In the body

temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient energy for the substrates to move at a fast rate‚ hence decreased the number of collisions with the enzymes. However

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

Does caffeine affect heart rate? Background Information: Caffeine is a bitter white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. A German chemist‚ Friedrich Ferdinand Runge‚ discovered it in 1819. Plants produce caffeine as an insecticide. It is found in varying quantities in the beans‚ leaves‚ and fruit of over 60 plants‚ where it acts as a natural pesticide that paralyses and kills certain insects feeding on the plants. Cocoa in South America‚ coffee in Africa

increase the competitiveness of domestic goods. The increase of nominal exchange rate can make the real exchange rate Increase‚ which will stimulate export and restrict import. It means that the trade balance will be improved. When the rate rises‚ the price of export is cheaper by counting in foreign currency‚ and the price of import in domestic currency increases‚ which is called the price effect. The decrease of exchange rate makes the price of export cheaper‚ the export volume increase‚ while the import

HEADER: HOW UNEMPLOYMENT RATE AFFECT COUNTRIES How the Unemployment Rate Affects a Countries Economy In 2010 Abstract This paper is about how the high unemployment rate has an affect on the economy. The high unemployment rate had an affect on the Gross Domestic Production as well how it had an affect on the economy as well. This paper covers when the Gross Domestic Production went up the unemployment rate had gone down as well. The high unemployment rate also

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development in the rate of reaction in all three experiments and that the higher the temperature the faster the rate of reaction is. The results were precise
