purpose of establishing the value of EtCO2. The sensor is usually placed in the monitor itself or maybe attached to the monitor. In this method‚ a water trap mechanism is required for the purpose of cleaning the sample tube. There is a chance of condensation of the humidified sample and gas and secretion from the patients often result in contamination of the sample line. These are some of the disadvantages faced by sidestream mechanism. The picture below depicts sidestream capnography- This picture

Psychoanalytic criticism Psychoanalytic literary criticism refers to literary criticism or literary theory which‚ in method‚ concept‚ or form‚ is influenced by the tradition of psychoanalysis begun by Sigmund Freud. Psychoanalytic reading has been practiced since the early development of psychoanalysis itself‚ and has developed into a heterogeneous interpretive tradition. As Patricia Waugh writes‚ ’Psychoanalytic literary criticism does not constitute a unified field....However‚ all variants

Asymmetric Catalysis in Intramolecular Reactions of α-Diazoketones. Abstract: Carbon-hydrogen insertion reactions involve the insertion of a carbene‚ a neutral carbon atom or molecule with two unpaired valence electrons‚ into an unactivated carbon-hydrogen bond. This reaction produces many commercially valuable compounds. The reaction itself involves the use of diazocarbonyl compounds which contain an N2 ligand on a carbon alpha to a carbonyl. The reaction is thermodynamically favourable as it involves

Lab 5 Oxidation of an alcohol CHM2123 Introduction: Oxidation is a key reaction in organic chemistry. Oxidation of an alcohol can produce aldehydes‚ ketones‚ or carboxylic acids. One of the methods of oxidation is an aldol reaction through carbon-carbon bonds. The oxidation oxidizes primary alcohols to aldehydes and secondary alcohols oxidizes ketones. Tertiary alcohols are converted to the common oxidizing agents. Scheme 5.1: Aldehydes can be oxidized easily to carboxylic acids in aqueous medias

The cloud appear when I released it because‚ you need three things‚ water molecules‚ cloud condensation nuclei - dust or air pollution‚ temperature or pressure changes 3. Describe the parts of the hydrologic cycle that took place in your best trial. Use the correct terminology. It is also known as the water cycle and it continuous movement

The process of distillation is commonly used to purify liquids. The process of distillation allows separation of distillates based on the temperatures at which they boil. Liquids with higher volatility boil at lower rates than liquids that are less volatile. Because of this when a mixture of two substances is created there will be a spike in the boiling point. At the spike the more volatile substance has vaporized and condense out of the mixture leaving the less volatile liquid. Thus the temperature

In a simple distillation‚ the liquids being separated boil below 150 0C at 1 atmosphere from nonvolatile impurities and another liquid that boils at least 25 0C higher than the first. A solution is heated to its boiling point. The vapor of the

and temp a liquid differs from a gas because the molecules of the liquid take shape of the container they are in. • The phase change in which a solid becomes a liquid is known as the melting. Liquid to gas is evaporation. Gas to liquid is condensation. Liquid to solid is freezing. Solid to gas is sublimation. Gas to solid is deposition. • The temp of a liquid during boiling increases • Under the same conditions of pressure & temp a liquid forms a gas because the molecules of the liquid
