As the most commonly prescribed tricyclic antidepressant, amitriptyline (AT) is frequently detected in wastewater, surface runoff, and effluents from sewage treatment plants, and could potentially reach agriculture land through the application of municipal biosolids or reclaimed water. Kaolinite is one of the most important soil components under warm and humid climate conditions. In this study,...

in this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using dried (bd) sargassum sp. (brown marine algae) and activated carbon (ac) prepared from it was examined. biomass, ph and the initial concentration of cr(vi), adsorption models and kinetic studies were investigated. the experiment was performed in a batch system and theeffect of solutio...

Responses to KCl and histamine and 45Ca movements were studied in trachea from normal and actively sensitized guinea-pigs. Sensitized tracheas were hyperresponsive and hypersensitive to KCl and histamine. 45Ca uptake experiments show that sensitized tracheal muscle behaves as normal except that the uptake of 45Ca in low concentration (0.03 mM) Ca2+ solution was higher and the number of binding ...

A pot experiment was conducted to investigate the solubility and redox species of antimony (Sb) in a relocated shooting range soil and its uptake by Lolium perenne L. and Holcus lanatus L. under different water regimes. After 1-week waterlogging, the total Sb concentration in soil solution decreased from ∼110 μg L(-1) to <20 μg L(-1), and slowly increased over the following 4 weeks, with the di...

abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...

To determine whether adding blood to a cardioplegic solution affects myocardial preservation, a randomized prospective study was carried out in 60 patients undergoing coronary revascularization to compare the effects of crystalloid potassium cardioplegics (group C) and potassium cardioplegic solutions to which blood has been added (group B) on markers of myocardial metabolism (lactate, inorgani...

In this study, the effects of three different bacterial isolates added to vase solution on life were investigated. All significantly increased gerbera cut flowers. While flowers in control was 3 days, period reached up 11 days kept containing bacteria. Daily water uptake decreased with increasing time all treatments. Although there some differences between treatments terms daily uptake, it has ...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...
