background and aim: 2,4-dichlorophenol (dcp) is a compound generated in a variety of industrial processes and also by chlorine disinfection of water polluted with phenolic compounds . dumping of dcp into the environment and water resources is of great concern because of the compound's intense odor and toxicity. dcp is very soluble and resistant to biodegradability so it cannot be removed ...
background: while in the open air the amount of radon gas is very small and does not pose a health risk, in confined spaces, radon can accumulate to relatively high levels and become a health hazard. exposure to high levels of radon has been associated with an increased risk of lung cancer, depending on the time length of exposure. radon level in dwelling of shiraz with 1,200,000 populations ha...
osteonecrosis (on) is characterized through the impairment of osseous blood flow that leads to the collapse of femur head. corticoid-induced on in rats and lipopolysaccharide (lps)-induced in rabbits are useful models to assess the efficacy of potential treatments on this disease. d-003 inhibits the mevalonate pathway, lipid peroxidation and prevents osteoporosis in rats through increasing the ...

در این پایان نامه، $1 + varepsilon$-پوشش های هندسی برای یک مجموعه از $n$ نقطه در صفحه و در فضای $mathbb{r}^{d}$ مورد مطالعه قرار می گیرند که این پوشش ها می توانند زمانی که نقاط آن ها حرکت می کنند به صورت کارایی نگهداری شوند. پوشش وابسته به حرکت در صفحه، دارای اندازه ی $o(n/varepsilon^{2})$ است و با فرض این که نقاط دارای مسیرهای حرکت چندجمله ای از درجه ی حداکثر $s$ هستند، تعداد $o(n^{2}eta(n))$ ...
background: iodine-123 (123i) is regarded as one of the best radionuclides for in vivo medical studies using single-photon emission computed tomography (spect) due to its suitable physical property. materials and methods: to design a new system in order to replace cryogenically solidified xenon target by the gas one, some necessary calculations are needed to be done such as finding the excitati...
sulfonic acid functionalized sba-15 (sba-pr-so3h) as a new nanoporous acid catalyst was used in the one-pot synthesis of polyhydroquinolines derivatives via the hantzsch four component condensation reaction of aldehydes, b-ketoesters, dimedone and ammonium acetate under solvent free conditions with short reaction time in excellent yields. sba-pr-so3h was proved to be an efficient heterogeneous ...
in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...
using hplc, the seasonal changes in the phenolic compound content of the leaves ofthe gemlik olive cultivar (olea europaea l) has been investigated with respect to theeffects on the alternate bearing of the cultivar. for this purpose, the leaf concentrations ofoleuropein, chlorogenic acid, caffeic acid, 3-hydroxycinnamic acid, scopolin and pcoumaricacid were analyzed at 10 day intervals around ...
this study presents an empirical relationship of suspended sediment concentrations (sscs) inthe coastal waters, which is derived from the conventional methods, to radiometer remote sensing reflectance values (rrs) and satellite data in coastal waters of kerala. an algorithm is then developed to utilize both in situ sscs measured from conventional methods and rrs values. this algorithm is valida...
