A hematocrit measures the percentage of blood that is comprised of RBC’s and can determine a needed transfusion. Fluid volume in the blood affects hematocrit values. Hematocrit levels rise with an increase in the number of RBC’s or a decrease in the plasma volume. An elevated hematocrit is most often associated with severe burns‚ diarrhea‚ and dehydration‚ where water in tissues decreases. The low level of plasma water concentrates the RBC’s leading to the condition‚ hemoconcentration. An elevated

example‚ periodic transitions between inclined flame and tulip-like flame (bended in the middle) takes place at f= 0.8‚ Vin= 0.7 m/s‚ as shown in Fig. 6a. Meanwhile‚ dynamics of the inclined flame are captured at f= 0.7‚ Vin= 0.5 m/s‚ as depicted in Fig. 6b. The common feature of these two flame dynamics is that their frequency is very low and they can be clearly observed with the naked eyes. The difference between these two cases is that the flame does not bend in the middle for f= 0.7. These two

The Effect of Chemicals on Fire In this lab we got to see the effect of chemicals on fire. We got to. See the flames change to different colors. The size of the colorful flame depended on how the Bunsen burner was turned on. I was sick when we were supposed to have the lab read‚ but I got it read the next day before class. During the lab I made sure to have the correct attired on: my goggles and apron. Ow ill go ahead and tell you five good safety precaution tips. One‚ never leave a lit

closely. I found out that the candle needs oxygen to burn‚ that it produces carbon dioxide similar to the way that my body produces carbon dioxide‚ and that a candle produces water as a second waste product. I learned that if I hold an object in the flame it becomes covered with soot which is unburned carbon fuel. Finally‚ I learned that neither the solid wax‚ nor the melted wax‚ nor the wick burns when a candle is lit. In fact‚ the wax itself is burning as a vapor or gas. Objectives 1. What happens

The ants scamper around in their dismay‚ of being thrust into the fire‚ and they continually charge back into the fire like the soldiers do. This passage represents what happens to the souls‚ bodies‚ and spirits of the soldiers when they are dumped into the flames of war. The fire that Henry dumps the ants into symbolizes

Welding is a method for the permanent assembly of metal parts. Arc welding can be divided at least three classes: arc welding‚ gas welding‚ and resistance welding. 1) Arc welding: Heat is generated by an electric arc and the parts are simply fused together and became one. In some cases electrode is used that provides a filler material. 2) Gas welding: The burning gas (oxygen and acetylene) raises the temperature of the part to be joined and a welding rod provides filler material. 3) Resistance

Justin Davis Period 1 9/24/2012 The Bunsen Burner and Boiling Water The Bunsen Burner is a piece of laboratory equipment that produces a single flame which is used for heating‚ sterilizing‚ and combustion. The gas used in Bunsen burners can be natural gas like methane‚ or propane‚ butane‚ or a mixture of both which are all liquefied petroleum gas. The Bunsen burner was named after a man named Robert Bunsen. In 1855 Robert Bunsen invited the Bunsen burner and it is now used all over the world
