کمبود آب شیرین در مناطق خشک و نیمه خشک انسان?ها را به استفاده از آب?های نامتعارف مانند پساب?های شهری، پساب?های صنعتی، زه?آب کشاورزی و روان?آب?های شهری سوق داده است. هدف از این تحقیق کاربرد شکل های مختلف یک نوع جاذب زیستی (استخوان شترمرغ) در بهبود کیفیت برخی از آب های نامتعارف (پساب صنعتی، آب آلوده به نیترات و آب شور) بود. در ابتدا، ظرفیت حذف سرب و جیوه به?وسیله فرم?های مختلف استخوان شترمرغ در آ...
Cerebral ischemia leads to brain injury via a complex series of pathophysiological events. Therefore, multidrug treatments or multitargeting drug treatments are attractive options in efficiently limiting brain damage. Here, we report a novel multifunctional compound oxopropanoyloxy benzoic acid (OBA-09), a simple ester of pyruvate and salicylic acid. This protective effect was manifested by rec...
The efficiency of optical brightening agents (OBAs), also known as fluorescent whitening agents (FWAs), has long been of interest in the production of uncoated fine paper, particularly in uncoated fine paper grades containing high-yield pulp (HYP). The increasing levels of whiteness and also the increasing HYP substitution in fine papers has made OBA efficiency an important issue. This paper su...
A research was conducted to study the perceptibility of color difference of color pairs, caused by OBA differences in paper substrates, and its relationship with quantitative measurement metrics. Based on the psychometric experiments conducted, the results show the utilization of the visual difference index (VDI), from 0 (no difference) to 3 (noticeable difference), to rate 27 color pairs with ...
Resonant optical second harmonic generation (SHG) is obtained from monolayers of 4-n-octyloxybenzoic acid (OBA) and noctyl-4-hydroxybenzoate (OHB) adsorbed at the water/ 1,2dichloroethane interface. The polarization dependence of the SHG from pure monolayers of OBA and OHB indicates that the molecular axis of the OBA molecules is tilted 6” closer to the surface normal than that of the OHB molec...
Two coordination polymers, [Ni(H2O)(L)(OBA)] (1) and [Pb(L)2(OBA)]·3H2O (2) [L = 2(4-fluorophenyl)-1H-imidazo[4,5f ][1,10]phenanthroline and OBA = 4,4’-oxybis(benzoate)], have been synthesized under hydrothermal conditions, and characterized by elemental analysis, and IR and UV/Vis spectra. Crystal data for 1: C33H21FN4NiO6, triclinic, space group P1̄, a = 13.8490(10), b = 14.932(2), c = 14.993(...
With the development of information technology, it’s possible to deliver advertising more accurately. Online behavioral advertising (OBA) is a kind of advertising which tracks individual online behavior in order to deliver advertising tailored to his or her interests. However, consumers still avoid advertising with more precise delivery. We can’t find out the measures which decrease OBA avoidan...
Systemic immune cell dysfunction is a typical feature of liver diseases and increases the risk of bacterial infection, especially spontaneous bacterial peritonitis. We evaluated functional properties of neutrophil granulocytes in blood and ascites of patients both with and without decompensated cirrhosis. We collected blood and ascites samples from 63 patients with cirrhosis and eight without c...
We report results of 48 semi-structured interviews about online behavioral advertising (OBA). We investigated non-technical users’ attitudes about and understanding of OBA, using participants’ expectations and beliefs to explain their attitudes. Participants found OBA to be simultaneously useful and privacy invasive. They were surprised to learn that browsing history is currently used to tailor...
Ors-binding activity (OBA) was previously semipurified from HeLa cells through its ability to interact specifically with the 186-basepair (bp) minimal replication origin of ors8 and support ors8 replication in vitro. Here, through competition band-shift analyses, using as competitors various subfragments of the 186-bp minimal ori, we identified an internal region of 59 bp that competed for OBA ...
