Faraday moved onto electrical conduction in gases. He used a device that he had made, called gas discharge tube. This device had sealed metal electrodes into a tube filled with gas, and then he lowered the pressure with a vacuum pump, after all that he connected an electrostatic generator. The gas inside the tube started to glow with a bright purple color once he had switched the generator on. Mainly because of this device he made he was able to state that electric discharge was created when current goes through a low pressure gas, the discharge color can be determined by the type of gas in the t... ... middle of paper ... ...
Several cryosurgery methods such as localized cryoprobes  and balloon ablation  have been developed as alternatives to hysterectomy to treat the dysfunction of the endometrium. However, these are localized techniques and sometimes there is still proliferation of the endometrium. A new technique is proposed that allows cryoablation to be achieved on the entire inner surface of the endometrium using a PFC fluid . The objective of this project is to develop an efficient treatment method for abnormal uterine bleeding by freezing the endometrium. It has been shown that a temperature of –30 C is required for destroy tissue necrosis .

Chromatography techniques Chromatography is an analytical technique used for separation of different components from a given mixture. The basic principle is the characteristic distribution or partition coefficient denoted as Kd which is due to the specific distribution of the analyte between two immiscible phases, the mobile and stationary phases. In a chromatographic system the stationary phase may be a solid, gel, a solid mixture or a liquid mixture which is immobilized. The mobile phase may be a gas or a liquid and is passed through the stationary phase to which the analyte is applied before passing the mobile phase through it. The differential affinity towards the mobile phase and stationary phase of different components of the sample mixture
The pulmonary systems on the other hand transport deoxygenated blood from heart into lungs and the oxygenated blood from the lungs to the heart. In summary, the physics of the circulatory system is a broad topic that can take days to expound. This is evident since the circulatory system obeys physics laws such as Poiseuille’s equation, bulk flow, Bernoulli’s principle and the principle of the law of conservation of mass. Diffusion, series and parallel arrangement of blood flow, gravitational force and single or double circuiting are all physics concepts applied in the circulatory system. The circulatory system works on the assumptions that blood is incompressible, vessels are rigid and that there are no losses or transfusions of blood in the system.
Also, the pressure drop of the piping system will be examined to determine the extent of, if any, fouling in the pipes. OBJECTIVES · Develop pump performance curves over a wide range of flow rates. This involves relating total head, horsepower input, efficiency, and NPSH as a function of pumping capacity (in gpm), similar to Figure 3-36A (Lab Manual). · Develop motor performance curves over a wide range of flow rates. This involves relating the current supplied to the motor, motor shaft rotational speed, motor efficiency, and the power factor as a function of the load of the motor, similar to the figure on page 21 of the Lab Manual.

Next Dalton’s law of partial pressure is used. The mixture of gas in the graduated cylinder was filled with two things: water vapor and air. Using the Dalton’s law, it can be concluded that the total pressure is equal to the pressure of air and the pressure of water vapor added together. This is an endothermic reaction which means that it absorbs heat, and when a reaction gains heat, it is repres... ... middle of paper ... ...inty between 1.0% (0.1/10.00*100) and 2.13% in the measured volume and 0.1/4.70*100). We also used a digital thermometer that allowed us to read the temperature readings from five degrees celcius to eighty degrees celcius.
For six years, Kepler taught, geometry, Virgil, arithmetic, and rhetoric. There he worked out a complex geometric hypothesis to account for distances between the planetary orbits-orbits that he mistakenly assumed were circular. Kepler then proposed that the sun emits a force that diminishes inversely with distance and pushes the planets around in their orbits. Kepler published his account in a thesis entitled Mysterium Cosmographicum (“Cosmographic Mystery”) in 1596. This work is significant because it presented the first comprehensive and logical account of the geometrical advantages of Copernican theory.
In the 1600’s Robert Boyle from Ireland explained the relationship between pressure and volume of a gas, which is now known as, Boyle’s Law. Boyle’s law states a volume of gas varies inversely proportional to its pressure at a constant temperature. The equation for Boyle’s law is written as P1 X V1 = P2 X V2 (Jardins 2013), which is used to calculate the settings on ventilators and other respiratory machines. For patients on ventilators this is one of the ways they can get help when they can’t breathe for themselves and need to get oxygen into the lungs. It also removes carbon dioxide from the body and helps patients breathe easier when they have to put a lot of effort into breathing.
