چکیده
The present study aims to evaluate the performance of evaporation-assisted humidification–dehumidification (E-HDH) desalination, specifically direct evaporative (DE-HDH), indirect (IE-HDH), and Maisotsenko (ME-HDH) systems. To achieve this, a thermodynamic modeling approach is utilized, which incorporates wet bulb effectiveness method, psychrometric relationships humid air, equations that govern heat mass balance. key indicators studied E-HDH desalination systems are estimated concerning operating parameters. results show ME-HDH system capable producing comparatively higher water production rate (WPR) ranging between 0.01 7.92 g/s as compared DE-HDH IE-HDH sensible cooling flux was observed be high at dry-bulb temperature (Tdb) 50 °C relative humidity (RH) < 0.2, having value 5.26 kW for system, followed by (3.23 kW) (3.11 due relatively flow rates. latent in case system. Minimum specific energy consumption from consequently, maximum gain output ratio (3.32) realized. In addition, realized an increment air velocity significantly improves WPR. accordance with climatic conditions Saudi Arabia cities, it has been Al-Hofuf Riyadh produce WPRs minimum consumption. Al-Hofuf, average WPR recorded 185.51 kg/day, (180.33 kg/day). required 0.042 kWh/kg 0.034 both accordingly.

Infective Causes of Stroke in Tropical Regions
Vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. In tropical areas stroke has some particular features related to the nature of torrid zones. There are some special causes of the stroke, mainly infectious, although some of them are non-infectious. The most important etiologies are malaria, tuberculosis, cysticercosis, s...
متن کاملThe marine algae Sargassum spp. (Sargassaceae) as feed for sheep in tropical and subtropical regions.
The objective of this study was to evaluate Sargassum meal as feed for sheep through the measures of in vivo digestibility, dry matter degradability, pH, ammonia and volatile fatty acids in rumen. The Sargassum algae used in this experiment were collected at the end of spring, when they are more abundant, bigger, and have completed their reproductive cycle. Four tons (wet weigth) were collected...

SUMMARY Thyroid hormones and their receptors in the ovaries are active regulators of reproductive function; both hyper-and hypo-thyroidism may result in estrous cycle disturbances. In addition, thyroid hormones elicit an extraordinary multiplicity of biochemical, cellular, and physiological responses, both in the simplest and the most complex organisms. On the other hand, glutamate, the main ex...
