Heat Exchangers - Research Paper Example   At the center of the heat exchanger lies two plates that are pinned together by pressing them and welding them together. There is a module whose function is to carry fluids in and out of the whole system. This combination is very efficient in offering high operating temperatures, and high pressure a factor that is vital in the heat exchange process.   The heat exchanger is able to function well without any gaskets. This means that it is able to work under these extreme conditions without any risk of leaking the fluid during the heat exchange process. Normally different types of heat exchangers are combined to come up with a more effective, cost friendly and efficient unit of the heat exchanger and the plate and shell heat exchanger is just but one example. This means that the fluids enter at the opposite ends of the unit enabling them to flow into the center of the exchanger. As the fluids come close to each other, there is an exchange of heat between the fluids.   As the flu id passes through the exchanger it either lose or absorb heat due to latent heat.  According to the nature of the heat exchange process, plates and shell heat exchangers are classified as indirect contact heat exchangers. The exchange of heat takes place by direct mixing of hot and cold fluids allowing transfer of heat and mass to take place simultaneously in a direct contact heat exchanger and such a unit is applicable only where the two fluids are either harmless when in contact or are desirable.

Care of Postoperative Patint with Right Fracture Neck of Femur with Essay

Care of Postoperative Patint with Right Fracture Neck of Femur with issue of Pain - Essay Example In addition to this, the patients dosage was changed from 300 mg of gabapentin before admittance, to 600 mg, before being reduced to 300 mg ten days after surgery. The patient controlled analgesic was used for four days following the operation, at which time a 20 mcg Butrans patch was applied in the morning. In compliance with warnings for this drug, it was necessary to reduce the patient controlled report will primarily focus upon the evaluation of the painkillers given to the patient in order to determine whether any relevant factors indicative of adverse reactions are indicated by the facts at hand, and the most likely prognosis given the information presented. Any analysis of patient outcomes must be evaluated with these vulnerabilities in mind. The conditions of this case study entail specific risk factors and comorbidities which will be discussed at length based on the findings of recent research on these subjects. There are various types of hip and femoral fractures that represent a growing health burden for the United Kingdom. Most of the attention dedicated towards this problem is directed towards the elderly population, specifically how to resolve challenges in perioperative care and anesthetics for elderly patients at high risk for femoral fractures. For this case study, it is necessary to assess the quality of care this patient has received, in addition to the most likely prognosis based upon the observed situation and the treatments prescribed. For this case study, background information will be provided concerning the conditions involved, specifically the complications resulting from geriatric hip/femur fractures. In cases of elderly patients, in light of consistent evidence that elderly patients are more susceptible to negative side effects from drugs, as well as various synergistic interactions. This is compounded by the fact that the elderly are more likely to take greater numbers
