Abstract Background: corrosion and scaling are of the most important characteristics of drinking water, affecting public health and water industry economy. The aim of the present study was to evaluate the corrosion and scaling potential of potable water supplied by Saqqez Rural Water and Wastewater Company. Materials and Methods: this was a descriptive study conducted on 142 samples taken from ...
the effect of cinnamomum zeylanicum essential oil (czeo) at two concentrations (0.02% and 0.04% v/w) on chemical composition, ph, water activity (aw), lipid oxidation, color stability and sensory characteristics of lyoner-type sausage stored at 4 ˚c for 40 days was investigated. the moisture content of the control sample was higher (p < 0.05) than czeo incorporated samples, while fat, ash and p...
Polypyrrole–hydroxyethylcellulose/TitaniumDioxide (PPy-HEC/TiO2) nanocomposite was synthesized via in situ chemical oxidative polymerization method at room temperature in water and water/ethyl acetate solution in the presence of ferric chloride (FeCl3). The effect of TiO2 nanoparticles and HEC on the characteristics of products such as thermal stability and morphology was investigated. The fabr...
بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
the aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. the cyanobacterium was isolated and purified on blue green algae medium number 11 (bg-11) medium. methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on bg-11 medium. the bi...
This paper focuses on the effects of the addition of an ionic liquid, 1-Allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([ABIM]TFSI), which has a high affinity for benzene, into the poly(vinyl chloride) (PVC) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. When aqueous solutions of 100~500 ppm benzene were permeated ...
Results of a field study carried out at Trinitapoli (Puglia region, southern Italy) on the irrigation of an artichoke crop with three types of water (secondary-treated wastewater, SW; tertiary-treated wastewater, TW; and freshwater, FW) are reported. Physical, chemical and microbiological analyses were performed on the irrigation water, and on soil and yield samples. The levels of most of the c...
the main objective of this study was using of canonical correlation analysis (cca) to find relations between 15 different variables of seed emergence and seedling growth related characteristics of seven important crop that were classified in three groups. the studied groups of variables were included physical characteristics (seed weight, seed length, seed density, water absorption and water co...
