under anaesthetic it had become apparent immediately that she needed to be assisted with her breathing, Intermittent positive pressure ventilation (IPPV) was performed until she began to breathe by herself. Jess was seen as a geriatric patient recovering from more than one major surgical procedure in one day and so intensive nursing care had to be maintained to a high standard. She would be experiencing a large degree of pain after the procedures and be less mobile; whilst it would be…

oversizing results in higher manufacturing and installation costs. The most appropriate metric to describe the performance of a heat exchanger is its thermal capacity, which is its ability to transfer heat between the hot and cold fluids at different temperatures. Thermal capacity depends on the design of the heat exchanger unit and the fluid properties that flow in the device. If the heat transfer surface is sufficient, the…

genetics of the organism, growth medium, and incubation conditions. (Saltman, Lab 9) Because bacteria reproduce by binary fission in a duplicate manner, the time of each doubling of the population is called the generation time. This generation growth is exponential. The purpose of this lab was to establish a growth curve to get a better understanding of the bacterium’s growth pattern under specific time segments and certain growth conditions. There are a few reasons to count the numbers of…

CNG Compressed Natural Gas (CNG) is a fuel obtained by compressing a natural gas to less than its 1 per cent volume at standard atmospheric pressure volume or 3600PSIA. It is use as an alternative automotive fuel with compressed natural conversion kit or compressed natural gas engine. PHYSICAL PROPERTIES OF COMPRESSED NATURAL GAS 1. It is colourless and odourless. 2. It is clean and has a clean burning. 3. It has low carbon monoxide emission. 4. It has no particulate matter emission. 5. For…

transfer from the hot combustion gases we can determine temperature distribution in the nozzle. If the temperature distribution and heat flux which are time dependent are given on the surface of wall we can find internal temperature distribution. This problem can be classified as direct heat problem. However many heat transfer problems which occur in practical take transient measurements at more than one location to find heat flux and temperature distribution on the wall. This is the inverse…

what goes on in the upper earth so they started making detailed instruments. Thermometer A thermometer is an instrument that measures temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is. Some of the first thermometers…

values for the partial pressure of O2 at sea level (with barometric pressure of 760 mmHg) in the following a. Inspired air b. Alveolar air c. Arterial blood d. Venous blood 1a- 149mmHg 1b-100-104 PaO2(mmHg) 1c-95-100mmHg 1d-40-50 mmHg Q2) Interpret the probable underlying cause when a person becomes unconscious and dies on exposure to an atmospheric pressure of 200 mmHg. When the human body is suddenly exposed to this pressure it is considered as a…

“the state of mind that expresses satisfaction with the surrounding environment.” This definition highlights subjective and psychological dimension of thermal comfort. 2.1.1 The heat balance In order to maintain a constant internal human body temperature, the heat which is continuously produced by the body must be dissipated to the environment (Jiao, 2010). From the energy exchange…
