Oxygen therapy

The heart works by pumping the blood throughout the internal circulatory system to deliver the oxygen and nutrients to the body cells. There are some features about the heart which allows more efficient respiration system. The heart have a left atrium and left ventricle. The left side of the heart is called systemic circulation which only pumps the…

air heating up and getting warmer, the water temperatures are heating up to, which is very bad for trout who have evolved to only live in cool water; trout are uncomfortable in water above about 20°C. When water temperature heats up it doesn’t allow oxygen to dissolve into the water like it should,…

Destin Briggs Lu Jack Chem 4235 11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium…

Kwong equations are mainly used as they are simple and a temperature-dependent correction is used for EOS constant A. van der Waals Equation van der Waals proposed the first cubic EOS in 1873. The van der Waals EOS gives a simple, qualitatively accurate relation between pressure, temperature, and molar volume. P=RT/(V-b)-a/V^2 where a is “attraction” parameter, b is “repulsion” parameter, and R is universal gas constant. Comparing this equation with the ideal gas law,P= zRT/v, we see that the…

4. Why PdO/TiON NP powders are chosen as photocatalyst? There are many reasons why PdO/TiON NP powders are chosen as a photocatalyst for MTBE mineralization under visible light. These reasons are listed and discussed as follows: 1- The synergistic effect. 2- The ease of synthesis. 3- The memory effect. 4.1 The synergistic effect Nowadays, modified TiO2 by metal and nitrogen is considered as one of the most promising TiO2 based materials for photocatalytic applications, which is able to…

Diels-Alder Reaction Objective: The objective of this lab was to do a diels-alder reaction using anthracene, maleic anhydride, and xylene to create 9,10-dihydroanthracene, 10-, -succinic acid anhydride. Experimental: Anthracene (1.00g, 5.61x 10-3 mol), maleic anhydride (0.75g, 7.61x 10-3 mol), xylene (5mL, 4.71x 10-2 mol), and a stir rod were added into a round-bottomed flask. The round-bottom flask was then moved to the hood where the it was attached to a distillation column, placed on…

INTRODUCTION Conformational isomerism is a type of stereoisomerism whereby the isomers are interconverted by rotations about the single bonds. There be terms used below such as eclipsed conformation, staggered conformation,dihedral angle and a few more. Eclipsed conformation is the conformation whereby the C-H bonds on one carbon is directly aligned with the C-H bonds of the adjacent carbon. When the C-H bond of one carbon bisects the H-C-H bond on the adjacent carbon, it is known as staggered…

Since suitable crystals for X-ray single crystal analysis was not obtained, to have reliable structural information, HR-TEM analysis of the product was carried out. The average size of the assembly calculated from HR-TEM measurement is found to be 2.8 nm which is in good agreement with the size of the previously reported Pd6L8 assembly where L is the non N-methylated (2.5nm, Fig. 2).9 As first step, to explore the catalytic activity of 1 in copper and phosphine free Sonogashira coupling reaction…

6.3. A. Microemulsions (135-143) Microemulsions are clear, stable, isotropic mixtures of oil, water, and surfactant, frequently in combination with a cosurfactant 135-137. Microemulsions have several advantages such as enhanced drug solubility, good thermodynamic stability, and higher transdermal permeability over conventional formulations 138,139. Many studies reported the use of microemulsions as topical drug delivery vehicles showed their ability to improve transdermal and dermal delivery…

Polarization curve Fuel cell creates 1.16 V of equilibrium potential between hydrogen and oxygen. However, the actual open circuit voltage is around 1 V due to temperature, pressure, and the concentration of the reactant. The ohmic loss is the resistance loss induced by the unique resistances of the component of fuel cell. And the concentration loss occurs when reaction rates of hydrogen and oxygen are faster than their supply rates. (1) The diffusion flux created according to…
