The unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate ion is strongly catalyzed by micelles of cationic and nonionic surfactants. The catalysis by cationic micelles can be enhanced by adding some electrolytes ...

A study of the electrolytic oxidation of three new C-4 nitrofuryl 1,4-dihydropyridines in nonaqueous aprotic medium is presented. Controlled-potential electrolysis (CPE) in dimethylformamide +0.1 M tetrabutyl-ammonium ...

Non-linear high-power devices produce electromagnetic noise (EMN) sources of great intensity that can disrupt and damage the surrounding electrical equipment and devices. This radiative phenomenon is very common at facilities ...

Observed electron velocity distributions in the Earth's magnetosphere and the solar wind exhibit a variety of nonthermal features which deviate from thermal equilibrium, for example, in the form of temperature anisotropies, ...

Electromagnetic ion cyclotron waves below the proton gyrofrequency in multicomponent plasmas have been extensively studied in recent years. However, it has recently been suggested that an often used analytical approach ...

It is well known that ion beam-plasma interactions can destabilize right- and left-hand polarized electromagnetic waves. However, these instabilities have been studied for frequencies less than the ion-beam gyrofrequency, ...

Objective. The goal of this study was to evaluate the electromyographic (EMG) activity of the anterior temporalis, suprahyoid, infrahyoid and trapezius muscles during tooth grinding at different jaw posture tasks. Materials ...

Background. Ankles and knees are commonly affected in people with hemophilia and thus are targets for prevention or rehabilitation. However, to our knowledge, no studies have evaluated muscle activity and safety during ...

Various correlation energy density functionals have been used to evaluate the electron affinities of the alkaline-earth atoms. A related approach based on polarization potentials was also tested. The results give evidence ...
