In this research, the effects of important parameters, including the molar ratio of acetic acid to sulfur(S) , sonication time, temperature, and hydrogen the molar ratio of peroxide to sulfur on the performance of ultrasound-assisted oxidative desulfurization were studied using the response surface method (RSM). To this end, a model fuel containing n-decane and dibenzothiophene at a concentrati...

A small and sophisticated optical depth sensor (ODS) has been designed to work in the atmosphere of Mars. The instrument measures alternatively the diffuse radiation from the sky and the attenuated direct radiation from the Sun on the surface. The principal goals of ODS are to retrieve the daily mean aerosol optical depth (AOD) and to detect very high and optically thin clouds, crucial paramete...

BACKGROUND Official statistics tend to underestimate the incidence of occupational disease (OD) nationally and regionally in Russia. OBJECTIVES The general aim was to obtain an accurate estimate of ODs in Murmansk Oblast in 1980-2010 and to determine the rate of specific types of ODs among cohorts of workers who had been exposed to the hazardous factors causing the disease. MATERIALS AND ME...

Platinum group metals (PGMs) usually exhibit promising aerobic catalytic abilities, providing a green and feasible oxidative desulfurization method. However, often, the PGM nanoparticles (NPs) get leached, catalysts are deactivated. In this work, Pt NPs with particle sizes of approximately 4–5 nm were encapsulated effectively uniformly on surface vanadium pentoxide (V2O5) nanosheets (with thick...

Background & Objectives Orphan Drugs (ODs) are medicinal products intended for diagnosis, prevention or treatment of rare diseases. Access to ODs is crucial for patients' health and quality of life. However, patients claim that access to orphan drugs is sometimes restricted, a phenomenon that has grown during the economic crisis. The aim of this study was to identify current problems and future...

In the dominant mouse mutant Odd Sex, XXOds/+ mice develop as phenotypic, sterile males due to male-pattern expression of Sox9 in XXOds/+ embryonic gonads. To test whether SOX9 was sufficient to generate a fully fertile male in the absence of Sry, we constructed an XY(Sry(-))Ods/+ male mouse, in which the male phenotype is controlled autosomally by the Ods mutation. Mice were initially fertile,...
