kiwifruit softening and the spread of gray mold on the fruit are the most important factors to be considered in kiwifruit storage life. in this study, the effect of calcium chloride (0, 1, 2, 4 and 8 percent) for 2, 4 and 8 minutes of dipping time were examined to improve the fruit physicochemical characteristics. following fruits being dried (24 hours), they were stored at 0.5oc and 85-90% rh ...
Grain-finished Hereford x Angus steers (n = 36) were assigned to one of three treatmentgroups. Immediately after jugular exsanguination, 12 steers were infused at 10% of live weight via the left carotid artery with a solution developed by MPSC, Inc. (St. Paul, MN) consisting of 98.52% water, 0.97% saccharides, 0.23% sodium chloride, and 0.28% phosphate blend (MPSC); 12 steers were infused at 10...
The SiO2-CaCl2 hybrid porous materials were prepared by the sol-gel method. This process was conducted by the hydrolysis and condensation of Tetraethyl orthosilicate (TEOS) by replacement of ethanol from alcogel and drying at the ambient temperature to obtain xerogel structure. The alcogel samples were synthesized from TEOS, EtOH, H2O, HCl, NH4OH and CaCl2, while the total molar ratio of the co...
Salt hydrates have issues of supercooling when they are utilized as phase change materials (PCMs). In this research, a new method was adopted to prepare a salt hydrate PCM (based on a mixture of calcium chloride dihydrate and calcium chloride anhydrous) as a novel PCM system to reduce the supercooling phenomenon existing in CaCl₂·6H₂O. Six samples with different compositions of CaCl₂ were prepa...
The effect of various concentrations of CaCl2 and KCl on egg white proteins during isoelectric precipitation of ovomucin was investigated in this study. At low concentrations of CaCl2 (<50 mM), lysozyme was the major contaminant in the precipitated ovomucin, whereas ovalbumin was the predominant one at high concentrations (>or=100 mM). At 50 mM CaCl2 concentration, the concentrations of both ly...
Fibers are important microstructural elements in many foods and calcium alginate fibers may find applications in the structuring of many food analogues. Fiber properties depend largely on their uniform diameter and mechanical properties. The main objective of this research is to production of fibers calcium alginate of regular diameter and to present the effect of concentrations sodium alginate...
Cadmium (Cd) ) may accumulate in soils which have been regularly fertilized with phosphate fertilizers which contain Cd originating in rock phosphate. Soil was taken from three sites in the wheatbelt of Western Australia which were estimated to have received different amounts of phosphate fertilizer over the past decade. The pH was adjusted with dilute HCl or CaC03. No Cd was added experimental...
The objective of this study was to examine the effectiveness of CaCl2 infusion in overcoming the toughness of meat associated with dietary administration of a beta- adrenergic agonist (BAA) to lambs. Thirty-two crossbred (1/2 Finnsheep X 1/4 Dorset X 1/4 Rambouillet) wether lambs were randomly assigned to receive 0 or 4 ppm BAA (L644,969; Merck, Sharpe and Dohme Research Laboratories) in a comp...
BACKGROUND Surgical castration is widely used to sterilize male dogs, but has significant impacts on time to perform the operation, recovery of the animals as well as cost, which can limit population control programs. Previous research has shown intratesticular injection of calcium chloride dihydrate (CaCl2) in saline to be a promising alternative to surgery. However, long-term azoospermia was ...
شوری یکی از عوامل مهم محدود کننده تولید محصولات کشاورزی در دنیا است. انواعی از نمک ها باعث شور شدن خاک می گردند که اثرات متفاوتی بر صفات مورفولوژیکی و فیزیولوژیکی گیاه دارند. .aloe vera l یکی از گیاهان دارویی مهم دنیا بوده که در درمان بسیاری از بیماری ها و عوارض پوستی استفاده فراوان دارد. به منظور ارزیابی اثر تنش شوری ناشی از نمک های کلریدسدیم و کلریدکلسیم بر میزان ژل، برخی شاخص های رشد، برخی ش...
