angiotensin-converting enzyme (ace) inhibitors including quinapril could exert a protective effect on cardiovascular system through endothelial system in normoglycemic and diabetic rats. the present experimental work was designed to study the vascular reactivity of aortic ring segments isolated from streptozotocin (stz)-diabetic rats treated for 4 weeks with nitro-l-arginine-methyl ester (l-nam...

in this work, the structural and electronic properties of folic acid molecule on functionalized (7,0)zigzag single-walled carbon nanotube was studied in gas phase on the basis of density functionaltheory (dft). furthermore, covalent interaction of folic acid with single-walled carbon nanotube wasinvestigated and its quantum molecular descriptors and binding energies were calculated. the dftb3ly...

To tackle the scale-up of Chemical Looping Processes, production efficient and affordable oxygen carriers appears paramount importance. Ilmenite is an ore-derived carrier which can be considered surely abundant cheap. The preparation characterization its reactivity are presented in following paper. paper describes briefly performance ilmenite relating it to other carriers, thermodynamic propert...

The kinetics of stearic acid, SA, removal by photocatalytic films are modelled using a log-normal distribution in surface reactivity, which shows that as the ρ, increases, so too does apparent order reaction, m, observed variation SA concentration, [SA], versus irradiation time, t. model is used to fit [SA] vs. t profiles exhibited three very different TiO2 films, namely Activ™ self-cleaning gl...

High energy ball milling of metallic powders leads to high reactivity in the milled mixture. The reaction is often faster and starts at a lower temperature. However, mechanisms responsible for this are not yet completely understood. aim study evaluate one possible activating factors heightened reactivity: nano-scale mixing reagents. Molecular dynamics was used analyze role an amorphous Ni–Al la...

The aim of this study was to determine whether socialized Jindo puppies would show different behavioral reactivity from non-socialized puppies. Puppies (n=12), 7 weeks of age, were divided into socialized and non-socialized groups. The socialized group from the 7th until 13th week after birth was provided a socialization program, and the non-socialized group was reared in a semi-isolated enviro...

Effects of treatment-associated variables on cerebrovascular autoregulation (CA) in acute brain injury patients remain unclear. As deficient CA is associated with worse outcomes and ideas about CA-steered management are emerging, this question relevant. We investigated effects norepinephrine propofol infusion rates hemoglobin concentration dynamic measurements reactivity as surrogate for CA. A ...

Coke corresponds to 2/3–3/4 of the reducing agents in BF, and by partial replacement coking coals with 5–10% bio-coal, fossil CO2 emissions from BF can be lowered ~4–8%. Coking coal blends 5% 10% additions bio-coals (pre-treated biomass) different origins pre-treatment degrees were carbonized at laboratory scale a bio-coal addition technical scale, aiming understand impact on properties (ash am...

Metallurgical coke with high strength and low reactivity is used in the ironmaking blast furnace. Replacement of some coking coal bio-coal was shown to result lower higher produced due introduction reactive carbon ash components catalyzing Boudouard reaction, but also lowering blend fluidity, which influences negatively. The current study aims investigate possibility counteract negative impact ...
