The barrier to internal rotation around the central C2–C3 single bond of a series of (1E)-monosubstituted 1,3-butadienes and (1E,3E)-1-Y-4-X-disubstituted butadienes, with Y=NH2 or OCH3 and X=NO2, CHO, COOH, CN, CF3, Cl or F, were studied at the density f... see more

Papiamento, a creole language spoken by approximately 200,000 people on three Caribbean islands: Aruba, Bonaire and Curaçao earned an official status at the beginning of the 21st century besides Dutch. Due to historical  easons and thanks to a unique... see more

The enzyme-linked immunosorbent assay (ELISA) is the most informative and versatile method of serological diagnostics. The possibility of detecting by ELISA specific antibodies of different classes allow to differentiate primary infectious process and its... see more

The article looks at recent research dealing with changes in the bile acid composition of the bile of outbred male rats under chronic social stress (social defeat in daily male confrontations, 14 days) when administered Corvitin (1 mg/kg, intragastrically... see more

To the problem of linear conjugation.

Soil environments are heterogeneous in their nature. This heterogeneity creates significant difficulties both in terms of construction practice and in terms of the mathematical modeling and computer simulation of the physical-chemical processes in these h... see more

Rapid advances in the life sciences have led to a radical transformation in thinking about what life is: we now compose living beings as synthetic life, from the ground up. “Life” has been multiplied and fragmented in molecular and database form and can b... see more

The rotational barrier RB around C–NH2 bond between the minimum and maximum states of 84 electron-withdrawing groups at para-position in aniline were studied at the density functional wB97X-D/6-31G** level. The rotational barrier was found to correlate st... see more

Successfully achieving the mission of the unmanned aerial vehicle (UAV) requiring a high gain data link between the UAV and the ground control station (GCS). The antenna of the ground station must has a narrow, precisely guided beam towards the UAV. Widen... see more
