There were no differences at admission between the groups in age‚ sex‚ previous types of feeding‚ previous duration of diarrhea‚ use of antibiotics‚ weight‚ height‚ weight-height percentile‚ prevalence of fever‚ overall status‚ degree of dehydration‚ and percentage of in-versus outpatients. Duration of diarrhea after enrollment was 71.9 ± 35.8 hours in group A versus 58.3 ± 27.6 hours in group B (mean ± SD;P = 0.03). In rotavirus-positive children‚ diarrhea lasted 76.6 ± 41.6 hours in group

alkene is the dominant product‚ the reaction follows Zaitsev’s rule. Zaitsev’s rule states that the major product of a β-elimination reaction is the most stable alkene [1].Acid-Catalyzed Dehydration is the elimination of a molecule of water from adjacent carbon atoms. An alcohol can be converted to an alkene by dehydration‚ which is often brought on by heating the alcohol with either 85% phosphoric acid or concentrated sulfuric acid [1]. The objective of this experiment is to dehydrate 3-methyl-3-pentanol

Today‚ the newer Natural Draft dehydrators use a 1‚000-watt element for heating as its heat source‚ or with the electric dehydrator using nine 75-watt bulbs totaling 675-watts‚ plus an electric fan. TYPES OF FOODS TO BE DEHYDRATED Solar dehydration or oven dehydration are good methods for meats‚ vegetables and fruits. If an oven is used‚ make sure there are numerous drying trays to fit on the oven’s racks‚ an accurate oven thermometer‚ and a small fan that is electric. The oven temperature should be

Experiment #7 Fall 2014 Dehydration of an alcohol NAME Nick Weinberger POSTLAB 1. Show the mechanism for the dehydration of -tetralol under conditions employed in the lab. Show all intermediates‚ and show electron flow with arrows. 2. What general mechanism most likely applies to this reaction (SN2‚ E2 etc)? E1 3. Why was acid employed in this reaction? The acid was used to protonate the leaving group (OH) to form water which is a much better leaving

vaporisation and secondly mass transfer is taken place as the water goes away from the food stuff (Earle‚ 1983). The Rate of drying depends on the type of food‚ the processing conditions and the design of the drier (Fellows‚ 2000). The practical of dehydration of tomatoes was carried out in a cabinet dryer that was operated at the temperature of 80°C. In the cabinet dryer the food material was spread out on the trays and heating was facilitated by an air current sweeping across the trays (Earle‚ 1983)

Dehydration Sci/241 Abbe Breiter-Fineberg 4/1/2012 Passing out‚ lethargy‚ constipation‚ dry mouth and even dry eyes are very few symptoms in the long list of signs to tell us that we are dehydrated. Being dehydrated is potentially very bad and if not taken care of a person can end up in the hospital or even dying. Many things can cause dehydration including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly‚

Running Head: DEHYDRATION IN HUMAN FACTORS Dehydration in Human Factors Allan Gorge Abstract Dehydration is an insidious disorder that plays a potentially deadly role in aviation and other aviation related specialties. We’ll take a look at the body’s composition of water‚ and the physiology of water loss and intake. We’ll also cover the different classifications of dehydration and there signs and symptoms. The dangers of dehydration in the role of

From the table‚ the result of dehydration of secondary alcohol is expected‚ and it undergoes E1 elimination. As supposed in the theory and mechanism‚ because elimination can occur both sides of secondary carbocation‚ so there are three products: 1-butene‚ trans-2-butene and cis-2-butene with three peaks. The main product is trans-2-butene‚ because it is the most stable compound. However‚ the result of dehydration of primary alcohol is not expected. It is supposed to form only one product‚ 1-butene

Experiment 2: Dehydration of an Alcohol: Distillation and Gas Chromatography Preparation of Methylcyclohexenes Purpose: The basic purpose of this experiment is to carry out the dehydration of an alcohol and isolate the reaction products by distillation. Gas Chromatography will be utilized to analyze the reaction mixture.
