امروزه محدودیت منابع آب و ضرورت افزایش کارایی مصرف آب آبیاری بر اهمیت برنامه ریزی دقیق شامل برآورد زمان و مقدار آب آبیاری افزوده است. این امر با شناسایی شاخص های خاک، بیلان آبی و کنترل رواناب سطحی مزرعه امکان پذیر است. با اندازه گیری شاخص های خاک (ظرفیت زراعی و نقطه پژمردگی)، و استفاده آن در برنامه ریزی واحد کنترل سامانه خودکار آبیاری به نحوی صورت گرفت که وقتی رطوبت خاک به ظرفیت زراعی رسید آبیا...
Abstract Scientific publications and newsfeeds recently focused on flushable wet wipes their role in sewage system blockages. It is stated that although products are marked as flushable, they do not disintegrate after being disposed of via the toilet. In this work it shown wetlaid hydroentangled lose initially good dispersive properties during storage condition. As a consequence, we suggesting ...
Advanced age-related macular degeneration (AMD) is the leading cause of blindness in the elderly, with limited therapeutic options. Here we report on a study of > 2 million variants, including 63,7 4 directly genotyped, mostly rare, protein-altering variants. Analyzing 6, 44 patients and 7,832 controls, we identify 52 independently associated common and rare variants (P < 5 × 0−8) distributed a...
1. Concentrations of retinal (vitamin A(1) aldehyde) in the plasma and liver of laying hens, mature cockerels, immature pullets and pullets undergoing sexual maturation have been measured. 2. The plasma of laying hens contained about 8mug. of retinal/100ml., about ten times that found in the plasma of mature cockerels and immature pullets. In laying hens that had received large doses of retinyl...
The expression of MuRF1 and MAFbx in a denervated muscle has previously been studied. However, the expression of MuRF1 and MAFbx in the recipient and donor muscles after muscle transfer for reconstruction of joint function has not been sufficiently investigated. Forty-two adult Sprague-Dawley rats were divided into 7 groups: normal, 1 w post-, 2 w post-, and 4 w post-musculocutaneous nerve tran...
In this study, aqueous solutions of 600 mg L of ammonia were oxidized in a trickle-bed reactor using Cu-activated carbon fiber (ACF) catalysts, which were prepared by incipient wet impregnation with aqueous solutions of copper nitrate that was deposited on ACF substrates. Experimental results showed that the total conversion efficiency of ammonia was 93% during wet oxidation over the catalyst a...
The metabolism of the cytotoxic lipid peroxidation product 4-hydroxynonenal was studied in perfused rat kidney. We investigated the total capacity of the rat kidney to metabolize 4-hydroxynonenal (HNE) and quantified the metabolites in the venous effluents as well as in the excreted urine. A rapid utilization of HNE was demonstrated, due to its immediate reactions with cellular compounds and it...
We report an experimental investigation of the near-solidus phase equilibria of a water-saturated analog of the Martian mantle. Experiments were performed at low temperatures (700–920 1C) and high pressure (4–7 GPa) using multi-anvil apparatus and piston cylinder device (4 GPa). The results of this study are used to explore the role of water during early melting and chemical differentiation of ...
