Because of its tenderness, long distance between field and consumer locations and unsuitable condition of transportation, 30 – 40 percent of strawberry fruits is wasted during the transportation between field to markets. One of the recommended ways for cutting down the wastes of strawberry is application of calcium salts after harvest stage to increase the content of Ca2+ in fruit flesh. For th...
It has been found possible to prepare the comparatively rare salt, calcium melibionate, in any desired quantity by electrolytic oxidation of a crude solution of melibiose. The melibiose solution , prepared from commercial raffinose, is subjected to electrolytic oxidation in the presence of calcium carbonate and calcium bromide, and the calcium melibionate is crystallized directly from t he elec...
[1] During the Ice in Clouds Experiment‐Layer Clouds (ICE‐L), dry lakebed, or playa, salts from the Great Basin region of the United States were observed as cloud nuclei in orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with a single‐particle mass spectrometer, sodium‐potassium‐magnesium‐calcium‐chloride salts were identified as residues of cloud droplets. I...
Green mature fruits of mango cv. SS-1 (Kala Chaunsa) were immersed for 10 minutes in 2.5, 5.0 or 7.5% calcium chloride (CaCl2.2H2O), calcium sulphate (CaSO4.2H2O) or calcium ammonium nitrate {Ca(NH4NO3)2} solutions. A control was also included in which fruits were dipped in fresh water for 10 minutes. The fruits were ripened at ambient temperature (25 ± 3 C) in boxes lined and covered with news...
Calcium salts are often prescribed in the prevention and treatment of osteoporosis. Adverse reactions have been described, mostly concerning to the gastrointestinal tract, parathyroid glands and bone resorption. We report the case of a 52-year-old woman who started treatment with 500 mg per day of calcium-pidolate. 90 minutes after the intake of the second dose, she experienced an itchy maculop...
This study was done in ehe wet marginal part of the Siahkooh playa (Kevir) in Yauf. Iran. which is located in the northwest of Ardakan. The abundance of Ca and SO. iones led to gypsum crystallization ncar the water table in the soil. From depeh to the soil surface, the caC~- CaSO .. ,2H,O -NaCI-H,<)-PCo, soil and water system change to CaSO •• 2H,<)Na1SO .. ·NaCI· Hz{). From water table (I...
Children receiving intravenous (IV) fluids, electrolytes and antibiotics are particularly prone to fluid escape (extravasation). Extravasation of chemotherapeutic agents, hypertonic fluids, sodium bicarbonate and calcium salts cause skin ulceration and necrosis(l). Children who are irritable or getting repeated seizures are more prone to IV bulge and fluid escape at the site, because of their t...
The intracellular localization of calcium during contraction of striated flagellar roots of the green alga Tetraselmis subcordiformis was investigated using calcium pyroantimonate and calcium oxalate cytochemistry and energy-dispersive X-ray microanalysis. Vesicles (0.25 - 0.50 microns diameter) located in the anterior-most region of the cell are calcium-sequestering organelles. These vesicles ...
This paper is based on a research on the problems of salt attack and rising damp in heritage masonry buildings. Amongst common building defects occurrences in heritage buildings, salt attack and rising damp are considered as the most challenging, particularly in building conservation. Rising damp and salt attack, a worldwide phenomenon, are major causes of decay to masonry materials. Moisture a...
Several reports have mentioned the existence of non-apatitic environments of phosphate and carbonate ions in synthetic and biological poorly crystalline apatites. However there were no direct spectroscopic evidences for the existence of non-apatitic environment of calcium ions. Xray Absorption Spectroscopy, at the K-edge of calcium, allows the discrimination between different calcium phosphates...
