iran is among the biggest emitters of greenhouse gasses in the world. agricultural sector has a remarkable role in non-renewable energy consumption and then, the environmental impacts in this country. in this regard, the environmental impacts of watermelon production as the most important melons produced in guilan province of iran were investigated through the life cycle assessment (lca) approa...

Abstract. Soil represents the largest phosphorus (P) stock in terrestrial ecosystems. Determining amount of soil P is a critical first step identifying sites where ecosystem functioning potentially limited by availability. However, global patterns and predictors total concentration remain poorly understood. To address this knowledge gap, we constructed database 5275 globally distributed (semi-)...

BACKGROUND Hypophosphatemia is a common metabolic complication in patients receiving specialized nutrition support. We changed our previously reported dosing algorithm because the low dose no longer appeared to be effective at increasing serum phosphorus concentrations. The purpose of this study was to evaluate the safety and efficacy of a revised weight-based phosphorus-dosing algorithm in cri...

To compare phosphorus intake and renal phosphorus regulation between thermally injured patients and multiple trauma patients, 40 consecutive critically ill patients, 20 with thermal injury and 20 with multiple trauma, who required enteral tube feeding were evaluated. Phosphorus intakes were recorded for 14 days from the initiation of tube feeding which was started 1 to 3 days postinjury. Serum ...

This article introduces an efficient, low cost, and clean (zero pollution) zone melting phosphorus purification technique. We have successfully removed arsenic from solid phosphorus by melting a narrow region and making the resulting liquid zone travel slowly through a relatively long ingot of phosphorus. This technique can reduce arsenic concentration in solid phosphorus from 100 ppm to 10 ppm...

A method of gas analysis is described for estimating carbon dioxide in the presence of nitrous oxide, using a modified Lloyd-Haldane apparatus. Some of the sample, after scrubbing with soda-lime, bubbles through the potash and this eliminates the solubility effect of nitrous oxide by equilibrating the standard potash solution with nitrous oxide at the tension of the sample analysed and eliminat...

of priesthood, to inviolable secrecy, whatever may be the nature of the information communicated by our patients. A crime, e.g., cannot be allowed to be perpetrated, so to speak, in our presence and with our cognizance during attendance on a household, and we must not, on any account, allow ourselves to be entrapped into being made unconscious confidants of some one who is bent on mischief. It ...
