Pulping in agro-waste processes are known to affect the chemical constituents of materials obtained. In this study, activated carbons (ACs) were prepared using precursors based on rice straw, husks and bagasse. The composition these was first determined order study influence components each sorption properties ACs ash content by calcination as main component present ashes is silica, which play ...

BirdLife International and several other institutions are running a campaign to save the lesser flamingos and maintain the integrity of Lake Natron. In November 1996, the BirdLife organisation in Tanzania (WCST) made a submission to the government's national environment management council (NEMC) that: " in the eyes of conservationists, the implementation of this project will result in an ecosys...

Drinking too much of the bubbly? It?s not clear if you?re a regular or diet soda drinker, but regular soda is a source of sugar, caffeine, sometimes coloring, and little else. One twelveounce can of regular soda typically contains eight teaspoons of sugar and 130 calories ? but zero nutritional content. The American Heart Association [2] recommends that individuals assigned male at birth limit ...

This research has produced foamed glass-ceramics from coal fired power station furnace bottom ash (FBA) and soda-lime-silica glass. The as-received FBA was wet milled with different additions of resultant slurry dried formed into a powder. powder pressed sintered at range temperatures fluxing agent (sodium tetraborate decahydrate), bubble stabilising additive (tri-sodium phosphate) bloating (ca...

This work introduces the principles and supplies first key parameters for replacing conventional ammonia-soda (Solvay) process with a new environmentally friendly sustainable process. For this, absorption of diluted CO2 (0.0153–1.2 vol %) in carbonated NaOH solutions was experimentally studied temperature range relevant direct air capture (DAC) middle Europe (5–20 °C). A dynamic model formulate...

This article is dedicated to the identification of perspective areas for disposal ash and slag waste from thermal power plants, namely generated at TPP-1 in Pavlodar. The composition was considered by methods X-ray fluorescence phase analysis order identify most suitable area their further use. Based on data obtained, it proposed use extraction precious metals, such as aluminum iron, alkaline l...

Superoxide dismutases convert superoxide anions to molecular oxygen and hydrogen peroxide, which, in turn, is metabolized by catalases and/or peroxidases. These enzymes constitute one of the major defense mechanisms of cells against oxidative stress and hence play a role in the pathogenesis of certain bacteria. We previously demonstrated that group B streptococci (GBS) possess a single Mn-cofac...
