Shock Shock is a syndrome characterized by decreased tissue perfusion and impaired cellular metabolism. This results in an imbalance between the supply of and demand for oxygen and nutrients. The exchange of oxygen and nutrients at the cellular level is essential to life. When a cell experiences a state of hypoperfusion‚ the demand for oxygen and nutrients exceeds the supply at the microcirculatory level. Classification of Shock The four main categories of shock are * cardiogenic‚: *

A Report of Experiment 1 Purification and Identification of An Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed

Characteristics of a Good Hydraulic Fluid Viscosity Viscosity is a measure of a hydraulic fluid’s resistance to flow. It is a hydraulic fluid’s most important characteristic and has a significant impact on the operation of the system. When a hydraulic oil is too thin (low viscosity)‚ it does not seal sufficiently. This leads to leakage and wear of parts. When a hydraulic oil is too thick (high viscosity)‚ the fluid will be more difficult to pump through the system and may reduce operating

Coolant and cutting fluid management Contamination of coolants and loss of cutting fluid through chip waste is one of the most time consuming and costly situations for a company. That is where fluid management comes into play. There are many ways to fight contamination and fluid loss. Loss of cutting fluid and coolants through chip waste can be solved with a briquetter. A briquetter is a machine that compresses your chips and turnings into a briquette squeezing out ninety percent of your expensive

For example‚ on the balloon’s motion‚ there are points where energy is lost. When the balloon is moving‚ the friction between the string and straw causes heat‚ and thermal energy. Another example is the sound energy created during the movement of the balloon‚ the energy has been lost. In order to improve this and make it more efficient‚ perhaps we could use a string that created less friction and then would result in a faster balloon

Abstract:Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment‚ two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates and streptomycin were utilized to determine if conjugation had occurred. When plated‚ the donor colonies appeared red and the recipient

Rosenhan experiment The Rosenhan experiment was an experiment into the validity of psychiatric diagnosis‚ conducted by David Rosenhan in 1973. The study is considered an important and influential criticism of psychiatric diagnosis. Rosenhan’s study was done in two parts. The first part involved the use of healthy associates who briefly simulated auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals in five different states in various locations in the United
