“These toxic chem-trails happen frequently here in these skies. It is absolutely frightening.” “The skies in Georgia are just horrible! They’ll spray and spray a blue sky until thicker clouds form, and it doesn’t rain it just mists on us all day with this acidic feeling mist! This...
Symbiosis-related acidic polypeptides released by the fungus during ECM formation share features with adhesins of fungal pathogens of animals and plants so might help attachment of the hypha to the host cell. A third group of up-regulated proteins are hydrophobins, secreted proteins that form an ...
The curiosity of the Alarcón Rise is that while the vast majority of lava flows along the ridge are basic (basalt) lavas, those associated with at least one volcano are clearly acidic, not basic. Researchers used a remote-control vehicle to collect samples and explore the volcano, which is...
Perhaps the best-known (and most visited) cenote is the Sacred Cenote (cenote sagrado) at the archaeological site of Chichen Itza.The caverns of the Yucatán Peninsula were formed as a result of the slow solution of limestone over thousands of years by percolating, slightly acidic, rainwater. ...
At the same time, fracture surface areas are also increased, which is important for the heat exchange area and heat extraction from the surrounding rock. Chemical stimulation involves the injection of an acidic fluid into the formation while using a fluid pressure lower than the reservoir breakdown...
aSince the 2-nitrobenzenesulfonamide group is stable under acidic [HCl (10 eq), MeOH, 60°C, 4 hr] as well as basic [NaOH (10 eq), MeOH, 60°C, 4 hr] conditions, it can be used extensively for protection of primary and secondary amines. Because of the mild conditions and easy ...
the shale oil in the micropores. The increase in micropore flow with increasing temperature may be due to the generally low maturity of the sample. With increasing temperature, the formation of organic compounds accelerates, the acidic matter produced by hydrocarbons dissolves, and the formation of...
However, when exposed to either strongly acidic or basic conditions, the reverse condensation reaction (depolymerization) is facilitated since water molecules created as a result of the gelation process can, in the presence of a catalyst, nucleophilically attack and cleave the Si-O-Si bonds (...
The rocks from the older caldera are intermediate to basic in composition, while those from the more recent caldera are acidic (high silica) rhyolites. Los Humeros The Los Humeros caldera is in the state of Puebla, close to its border with Veracruz. It is 55 km west-north-west of the ...
By means of the present invention, could be demonstrated through heavy metals leaching tests in acidic and basic solutions, that the Pb presents an effective immobilization in all the mixtures. The present invention is also related to a mixture that is resistant to chemical agents, what was ...
