“Concentrated solar power” (CSP) and thermal energy storage (TES) are promising renewable technologies, which have gained increasing interest practical application in recent years. CSP TES systems typically utilize molten salts such as the so-called “solar salt”, a mixture of 60 wt.% NaNO3 40 KNO3, for heat transfer storage. The overall efficiency commercially operating is currently limited, be...

Weanling male rats of Wistar strain were divided into 3 groups and housed in cages with wire bottoms. The rats of group 1 were fed on control diet having the following composition: vitamin free casein, 18; sucrose, 46; glucose, 23; salt mix ture,* 4; soybean oil, 6; vitamin mixture, 1: and agar powder 2. The vitamin mixture was prepared as follows (in mg/1008 of diet): thiamine HCl, 2,4; ribofl...

A one-year study was conducted to measure the effects of balanced supplementation to improve biosustainability of a 110 head goat herd in Mexico in terms of economic feasibility on limited pasturing range land complemented with an alfalfa hay forage bank and grazing corn stubble. Average weight of adult females was 52.410 5 kg, yearlings 40.0 3 kg at ®rst kidding. Average total lactation milk p...

cellulase production by the fungus trichoderma reesei was studied using sugar beet pulp (sbp) as a substrate. the subculture medium was a salt solution consisting of kh2po4, cacl2, etc. fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°c for 1-2 generations (two days for each generation) and were then used as an inoculum. exponential cells were inoculated into a medium contain...

Molten salts have been used in solar thermal energy storage due to their high density, low cost and excellent chemical stability. However, application is limited by “bad days” such as cloudy days winter because the weak concentrated radiation cannot melt salt. The current study indicates that through mixing pure salts, melting point of molten salt can be decreased significantly while latent hea...

This paper investigates effects of different additives on morphology and subsequently, separation performance of asymmetric flat sheet Polyvinylidene fluoride (PVDF) membranes to separate CO2 using membrane contractor. Five different additives from different chemical families including Lithium chloride (salt), Polyethylene glycol 400 (polymer), glycerol (weak anti-solvents), methanol...

Water is an essential natural resource, and its contamination important issue at present. This study aimed to increase the techniques that can be used clean reuse industrial wastewater by studying feasibility of aqueous two-phase system eliminate phenolic compounds from systems. The was prepared using two hydrophilic ionic liquids based on dicyanamide anion, 1-ethyl-3-methylimidazlium [EMim] [D...

Introduction: Cadmium is recognized worldwide as a toxic metal. In this study, Solvent-Assisted Dispersive Solid Phase Extraction (SA-DSPE) combined with Flame Atomic Absorption Spectrometry (FAAS), was used for determination of trace amounts of Cadmium (Cd-II)) in drinking water samples.
