The purpose of this paper is to estimate the quantity and quality of the useful energy that could be converted to work, this analysis was carried out based on the energy and exergy analysis by using the first and second laws of thermodynamics. This paper study the effect of varying the ambient temperature on the performance of the turbine. Results showed increasing in exergy destruction in the turbine solely and in each of its three components(Air compressor, Combustion chambers and the gas turbine) with increasing in ambient temperature. Also results showed by keeping the load unchanged, the exergy destruction are bigger in higher ambient temperatures than in lower ones. The exergy destruction concentrated in the combustion chambers, where the percent of exergy destruction in the combustion chambers to the total exergy destruction in the plant was(87%) followed by the air compressor(9%) and the lower exergy destruction was in the gas turbine(4%).
The study was conducted by taking blood samples from those recovering from the Corona virus, specifically 20-28 days after infection. The number of samples was (54) patients, collected from the period among six months (Mars to September). Blood samples were taken from patients recovering from Covid 19 from the hospitals of Karbala and Baghdad, the information of the samples was recorded, and laboratory analyzes were done to measure the level of ferritin, and the complete blood picture was measured. The data of patients were studied Biochemistry lab with biochemical tests.
The results were obtained and indicated that most of the recovered patients with Corona virus had symptoms of acute anemia , and after conducting a ferritin analysis, it was found that their ferritin level was high, which caused an increase in stored iron and a lack of iron associated with hemoglobin. The research recommended continues taking vitamins and minerals necessary for the health of the body.
This study involved the collection of (90) samples of women serum which included (30) serum samples collected from women before menopause (reproductive women) in the age range of (22-43) years and were considered as (group A- control). While, (group B) included (30) serum samples collected from women using oral contraceptive pills between the ages of (22-43) years old. Whereas, another (30) serum samples were collected from women after menopause between the ages of (43-54) years and were considered as (group C). All of the collected serum samples were subjected to a number of serological and chemical tests for the measurement of (E2, HDL, LDL and Ca). Then, the obtained data were statistical analyzed and results showed a significant decrease (p˂ 0.05) in (E2 ,Ca and HDL) levels in menopausal women compared to that of the normal healthy controls. While, there were non-significant decrease (p> 0.05) in (E2, Ca and HDL) levels in women taking oral contraceptive when compared to the normal healthy controls. On the other hand, a significant increase (p˂ 0.05) was recorded in LDL level in menopausal women compared to that of the normal healthy controls whereas, no-significant increase (p˃ 0.05) in the LDL level in women taking oral contraceptives when compared to the control women.
Alkaline hydrolysis rates coefficients for the series of methyl 3-(7-substituted-1-naphthyl) propynoate was calculated in 70%v/v dimethylsulphoxide-water at various temperatures (25,30,40, and 50̊ C). The pKa values of 3-(7-substituted-1-naphthyl) propynoic acid and (E)- 3-(7-substituted-1-naphthyl) propenoic acid calculated in 80%w/w 2-methoxyethanol-water at room temperature (25.0̊ C). logk2 of esterification rate coefficients for 3-(7-substituted-1-naphthyl) propynioc acid and (E)-3(7-substituted-1-naphthyl) propenioc acid with DDM have been measured at 30.0̊ C. Reversed substituent dipolar effects were found in the ionization reaction. In the esterification reaction with DDM the result show similar but reduced substituted effects. Rate retardations was found in the alkaline hydrolysis. It could be result from steric effect or reversal of substituent dipolar effect with a combination of steric effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
