the effect of vanillin on the corrosion behavior of aa6061 al alloy in 3.5% nacl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (en) techniques. vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. the best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

N-Alkylation at the ring nitrogen of the D-galactosidase inhibitor 1-deoxygalactonojirimycin with a functionalised C ₆alkyl chain followed by modification with different aromatic substituents provided lipophilic 1-deoxygalactonojirimycin derivatives which exhibit inhibitory properties against β-glycosidases from E. coli and Agrobacterium sp. as well as green coffee bean α-galactosidase. In prel...

Stichococcus bacillaris Naeg., a green soil alga, can grow in the presence of methionine sulfoximine (MSX), an inhibitor of glutamine synthetase, by maintaining a high level of NADPH-glutamate dehydrogenase activity. MSX-grown cells can utilize both NH(4) (+) and NO(3) (-) as nitrogen source for growth. [(14)C]Methylammonium is not metabolized by S. bacillaris, and is transported by a carrier s...

AZD2014, an inhibitor of mTORC1 and mTORC2, is highly effective in ER+ breast cancer when administered using intermittent or continuous schedules. Sylvie M. Guichard, Jon Curwen, Teeru Bihani, Celina M. D’Cruz, James W.T. Yates, Michael Grondine, Zoe Howard, Barry Davies, Graham Bigley, Teresa Klinowska, Kurt G. Pike, Martin Pass, Christine M.

Abstract: The performance of an Imidazoline based commercial corrosion inhibitor in CO2 corrosion of a gas-well tubing steel was studied by employing Electrochemical Impedance Spectroscopy (EIS) technique. Inhibitor performance was investigated by means of its efficiency at various concentration and also its behavior at various exposure time. EIS results showed that inhibitor interaction to...

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...

Carbon steel is one of the most employed materials in many industrial sectors due to its unique physical and mechanical properties. However, within a certain period time, carbon steel-based are susceptible corrosion under operating conditions inhibitors important extending limit use steel. In this study, influence protoporphyrin from animal blood hemin as an eco-friendly inhibitor for T22 acidi...

Abstract Introduction: Matrix metalloproteinase 2 is one of the inflammatory mediators that is involved in nociceptive processing and its production is regulated by many inflammatory factors such as nitric oxide. We studied the role of MMP-2 on the analgesic effects of nNOS inhibitor. Methods: Considering that nitric oxide has many roles in pain processing, we studied the CSF levels of MMP-2 ...

this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...

iced tea is a world popular beverage,for example about 80% of people in italy and united states, consume iced tea as a thirsty-quenching beverage. however, it is also believed that iced tea contains health benefit components. process of iced tea involved tea solid extraction and then mixing with edible acids, flavors, sugar or non-nutritional sweeteners. in this research, regarding to the deman...
