The article dwells upon the study of current physico-chemical status alluvial dark-humus soils floodplain hayfields Volga-Akhtuba and Volga delta. Alluvial are formed in special semiaquatic conditions; they result soil-forming processes. Considered to be dynamic both natural anthropogenic conditions. They have subordinate remain barriers accumulators various chemical elements while performing a...

The effects of external pH (7.0-8.0) on intracellular Ca(2+) signals (Ca(2+) sparks and Ca(2+) waves) were examined in smooth muscle cells from intact pressurized arteries from rats. Elevating the external pH from 7.4 to 7.5 increased the frequency of local, Ca(2+) transients, or "Ca(2+) sparks," and, at pH 7.6, significantly increased the frequency of Ca(2+) waves. Alkaline pH-induced Ca(2+) w...

The article presents the results of studies influence a large industrial enterprise on soil cover. It is shown that for production building materials significantly affects agrochemical and biological indicators soils. This manifested primarily in change acidity soddy-podzolic sandy loamy soils shift pHKCl index towards alkalization. has been established with slightly alkaline (pHKCl from 7.06 t...

In this study, Co-modified alkalinized g-C3N4 (named Co-CNK-OH) was prepared for the Fenton-like photocatalytic degradation of tetracycline (TC) via a simple yet effective calcination–impregnation method. all samples CNK-OH with different Co2+ loadings, Co-CNK-OH catalyst optimal content (9%) exhibited highest catalytic activity, 87.1% removal and 50% efficiency total organic carbon (TOC). Mech...

Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC a French fries coating to reduce oil uptake. This research aims study the utilization of OPEFB coating. consists two stages. The first stage is cellulose extraction and synthesis. synthesis through alkalization, methylation, propylation, neutralization. second use with different conce...

The value rheology of drilling mud must be in accordance with the conditions wellbore that do not lead to occurrence problems at time drilling. One efforts improve is by adding Carboxymethyl Cellulose (CMC) which useful for increasing viscosity and binding water. This study aims identify effect on use CMC originating from jackfruit skin rheological properties mud. Jackfruit an underutilized org...

This study aims to investigate the effect of alkalization and chemical coupling methods on surface adsorption properties waste cotton cotton/polyester yarns. The simple cheap alkali treatment was performed using 10% 18% NaOH solution, while method involved combining yarns fly ash, sodium carboxymethyl cellulose alginate as binders. Morphological characteristics unmodified modified were analyzed...
