یون‏زدایی خازنی یک فرآیند نمک‏زدایی از آب شور مبتنی بر جذب یون‏های نمک برروی الکترودهایی است که به آنها یک ولتاژ مستقیم اعمال شده است، درست مشابه فرآیندی که در یک ابر خازن رخ می‏دهد. در ابتدا کارایی سه نوع الکترود مورد بررسی قرار گرفت؛ الکترود معمول حاوی کربن فعال (ace)، الکترود با افزودن 5 درصد از رزین‏های تبادل یون (ier5)، و الکترود با افزودن 10 درصد از منگنز دی اکسید (mnoe10). بررسی مشخصات ع...

Wheat Triticum aestivum L. is one of the most important agricultural products, and meets highest nutritional needs humans in various countries. This study aims to evaluate compatibility stability 25 wheat genotypes for two crop years five regions (Karaj, Qazvin, Isfahan, Varamin Damavand) a randomized complete block design with three replications. The results variance analysis additive main eff...

Soil ammonium toxicity can decrease plant growth, and many crop species have low resistance to ammonium, including canola, an economically important crop. Different genotypes may differ in their toxicity, therefore determining if there are that exhibit variation ability tolerate soil is a research priority. Here, we evaluate how impacts canola root shoot growth characterise differences among re...

Genotype-environment interaction (GEI) is very important for breeders. It considered a complicated issue in breeding programs to obtain stable and high-yielding genotypes release new genotypes. This study was conducted achieve genotype that adaptive climatic conditions of potato-producing regions Iran. A total 20 potato lines along with five commercial varieties (Savalan, Agria, Caesar, Luta Sa...

Vaccination and infection can elicit protective and nonprotective antibodies to the fungus Cryptococcus neoformans in mice. The effect of nonprotective antibodies on host defense is unknown. In this study we used mixtures of protective and nonprotective monoclonal antibodies (mAbs) to determine if nonprotective mAbs blocked the activity of the protective mAbs. Antibody isotype and epitope speci...

BACKGROUND Studies of environmental microbiota typically target only specific groups of microorganisms, with most focusing on bacteria through taxonomic classification of 16S rRNA gene sequences. For a more holistic understanding of a microbiome, a strategy to characterize the viral, bacterial, and eukaryotic components is necessary. RESULTS We developed a method for metagenomic and amplicon-...

We consider a stochastic model for a defined-contribution pension fund in continuous time. In particular, we focus on the portfolio problem of a fund manager who wants to maximize the expected utility of his terminal wealth in a complete financial market with stochastic interest rate. The fund manager must cope with a set of stochastic investment opportunities and two background risks: the sala...

The P4 helix is an essential element of ribonuclease P (RNase P) that is believed to bind catalytically important metals. Here, we applied a combination of NMR residual dipolar couplings (RDCs) and a recently introduced domain-elongation strategy for measuring "motionally decoupled" relaxation data to characterize the structural dynamics of the P4 helix from Bacillus subtilis RNase P. In the ab...

The value that brokers generate depends on both the quality of their investment recommendations and their clients’ counterfactual portfolios. To identify counterfactual portfolios inside a defined contribution retirement plan, we exploit time-series variation in access to brokers. When brokers are available, the correlations with age, income, and educational attainment suggest that brokers are ...
