Transformation and crystallization energetics of synthetic and biogenic amorphous calcium carbonate.
Amorphous calcium carbonate (ACC) is a metastable phase often observed during low temperature inorganic synthesis and biomineralization. ACC transforms with aging or heating into a less hydrated form, and with time crystallizes to calcite or aragonite. The energetics of transformation and crystallization of synthetic and biogenic (extracted from California purple sea urchin larval spicules, Str...
متن کاملAbsorption of calcium from a leafy vegetable rich in oxalates.
I. Plant foods, especially green leafy vegetables, are the cheapest and richest source of calcium in developing countries and are recommended in balanced diets. Hence it was worth while obtaining further information about the availability of Ca from these commonly-consumed green leaves. 2. The green leafy vegetable belonging to Amaranthus spp. was taken as a suitable experimental model because ...
متن کاملEvaluation of soluble oxalates content in infusions of different kinds of tea and coffee available on the Polish market.
BACKGROUND Tea and coffee are the potentially rich source of oxalic acid, which can act as a antinutrient. OBJECTIVE The aim of this study was to determine and evaluate the content of soluble oxalates in teas and coffees available on the Polish market. MATERIAL AND METHOD The green, red and black teas, and black natural ground and instant coffees were used for preparing the infusions. The m...
متن کاملConsideration of Water Productivity for Farm Water Management in Different Conditions of Water Availability for Dominant Summer Crops
ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...
متن کاملEFFECTS OF DIFFERENT SALINE CONDITIONS ON PROLINE AND ION CONTENT OF TWO COLZA CULTIVARS
The effects of non-saline soils with low, medium and high salinity, (EC = I, 7, 10 and 18 decisiemens per meter, respectively) on ion content and proline, were studied in different organs of two colza (Brassica napus L.) cultivars, namely, PF 7045.91 and Hyola 401, in pot culture conditions and also the efficiency of comparing these changes were used as a tool for this study. Plants were grown...
