We show that the annual mean value of phosphorus content in plant is strongly correlated to the annual mean concentration of phosphate in water, for all the three species. In contrast, there is no definite relation between P-plant tissue and the concentration of total P in the sediment....
A field experiment for four consecutive rainy (kharif) seasons from 2006 to 2009 was conducted to study the response of P-enriched organic (compost and vermicompost) and inorganic (dia-ammonium phosphate) sources of phosphorus and methods of its application (broadcast and placement) to groundnut (...
Further, groundwater is polluted by various contaminants, out of which the PTEs are the major contaminants7. Landfill leachate, application of pesticides, and phosphate fertilizers are some of the anthropogenic activities that can also significantly actuate fluoride contamination in groundwater8. In a ...
In the past few decades, however, pollution has caused a deterioration in the quality of the water and sediment in Lake Bafa. The main sources of pollutants are agriculture, the Büyük Menderes River, runoff from settlements without sewage treatment systems, untreated wastewater from aquaculture ...
Harnessing its reactivity towards various nucleophiles such as amines, alcohols and pseudohalogenides, 1[OTf] then provides redox-neutral access to a range of value-added PV chemicals downstream of low-cost phosphoric acid or other phosphate sources....
We analyze the physical limits on the maximum extractable power of the single-frequency Yb3+-doped phosphate fiber lasers and amplifiers. Our analysis indi... JP Lambert,V Morrison,PW Brunt,... 被引量: 6发表: 1992年 WATER-HOLDING CAPACITY OF VARIOUS SOURCES OF PLANT FIBER Published values on...
bioavailability from the approved food additive leavening agent acid sodium aluminum phosphate, incorporated in to a baked good, is lower than from water. ... RA Yokel,RL Florence - 《Toxicology》 被引量: 107发表: 2006年 Evaluation of the effect of mitomycin-C on the bioavailability of technet...
There is provided a dietary or health supplement comprising an effective amount of a micronutrient selected from the group consisting of phosphate derivatives of tocopherol, ubiquinol, ascorbic acid, tocotrienol, retinol and mixtures the... SM West,D Kannar - EP 被引量: 105发表: 2003年 Soil and...
The following parameters were measured in the lake water: temperature (16.1°C), conductivity (250μS/cm), secchi disk depth (1.9m), dissolved oxygen (DO) (9.36mg/L), nutrients [ortho-phosphate (78.9μg/L), nitrate+nitrite (707.5μg/L) and ammonia-nitrogen (264μg/L)], chlorophyll ...
