Sorption of atrazine on soils subjected to three different organic amendments was measured using a batch equilibrium technique. A higher K(F) value (2.20 kg(-1)(mg L(-1))(-N)) was obtained for soil fertilized with compost, which had a higher organic matter (OM) content. A correlation between the K(FOC) values and the percentage of aromatic carbon in OM was observed. The highest K(FOC) value was...

in this project, different nettle plants from north regions of iran including tonekabon, amol and gorgan were collected. the oil was extracted using soxhlet extraction apparatus and was subjected to series of physical and chemical tests and determinations consisting of refractive index, melting point, smoke point, nonsaponifiable matter, iodine value, saponification value, peroxide value, totox...

A study was conducted to evaluate the cooking and eating quality of Ofada rice. Quality parameters measured were; volume increase, grain elongation (GE), water uptake (WU), cooking time (CT), solids in cooking gruel (SCW), gelatinization temperature (GT) and amylose content (AC). The result showed that Ofada rice had high cooked rice volume with length and breadth increase of 152.54% and 87.85%...

In recent years, studying the dietary preferences and livestock grazing behaviorhas attracted lots of attention due to manage and improve the efficiency of rangelands. So,in this study the foraging behavior and diet selection of Tali goat was investigated in theChabahar Rangeland during 2008-2010. Data were collected and analyzed for speeds oflivestock, covered distance, time of grazing, restin...

BACKGROUND Bowlby and Ainsworth hypothesized that maternal responsiveness is displayed in the context of infant distress. Depressed mothers are less responsive to infant distress vocalizations (cry) than non-depressed mothers. The present study focuses on acoustical components of infant cry that give rise to responsive caregiving in clinically depressed (n = 30) compared with non-depressed moth...

BACKGROUND There are limited data regarding the relative merits of biomarkers as predictors of mortality or time to initiation of antiretroviral therapy (ART). METHODS We evaluated the usefulness of the CD4 cell count, CD4 cell percentage (CD4%), human immunodeficiency virus type 1 (HIV-1) load, total lymphocyte count (TLC), body mass index (BMI), and hemoglobin measured at 32 weeks' gestatio...

Two methods for the extraction, identification and quantification of the highest occurrence and lowest perception threshold off-flavours in fifteen different samples of Brazilian Pilsner beers were developed. For this purpose, headspace solid phase microextraction in combination with a gas chromatography coupled to a mass spectrometric detection (HS-SPME-GC-MS) as well as headspace extraction i...

Danzhixiaoyao Wan (DW) is a common 10 herbs formulation in China for regulating several clinical conditions affecting women. This research tried to explain one of DW's functions, purging heat, using in vitro pharmacological analyses. The whole formulation and each single herb of DW were compared based on antioxidant activity with the oxygen radical absorbance capacity (ORAC) assay, and for thei...

This study was designed to determine the infl uence of Ca and P intake by young, gestating sows on the growth and skeletal development of their developing piglets and if smaller birthweight piglets are at greater risk from mineral insuffi ciency during gestation. A total of 30 sows were randomly assigned to 1 of 3 dietary Ca:P treatments. At birth, the smallest and a normal-sized piglet from ea...
