Dibenzothiophene (DBT), benzothiophene (BT) and thiophene (T) were catalytically oxidized to their corresponding sulfone products by H2O2 in the presence of magnetically recoverable polyoxometalate-based nano catalyst. Different extracting solvents including ethanol, acetonitrile, and dimethylformamide were tested. The best results were obtained by ethanol extraction. The oxidative desulfurizat...

A molecular-dynamics simulation method has been applied to investigate the influence of the mobile-phase composition on the retention of solutes in HPLC. The distribution profiles of the distance between two atoms in ODS ligands were constructed to characterize the conformation of ODS ligand molecules. The distinct difference of ODS conformation is observed by comparing molecular models consist...

Dependencies play an important role in databases. We study order dependencies (ODs)—and unidirectional order dependencies (UODs), a proper sub-class of ODs—which describe the relationships among lexicographical orderings of sets of tuples. We consider lexicographical ordering, as by the order-by operator in SQL, because this is the notion of order used in SQL and within query optimization. Our ...

Steroidogenic acute regulatory protein (StAR) regulates the rate-determining step of steroidogenesis. StAR is expressed at a very low level in the white matter of the normal human brain, but is highly expressed in several brain neoplasms including oligodendroglioma (OD). The aim of this study was to identify the different patterns of gene expression low-grade OD and high-grade OD. We carried ou...

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...

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,...

A espécie humana, pré-histórica e extrativista, competidora da natureza ecocêntrica em seus primórdios, perverte sua lógica na modernidade com o modo de produção capitalista, tornando-se antropocêntrica tendendo ao estresse biosfera à destruição do planeta. Instituições como a ONU, para reverter cenário apocalíptico, propõem os ODS (Objetivos Desenvolvimento Sustentável) Agenda 2030. Ciência Ag...

The goal of this project is to generate data that demonstrate and quantify earlier improvements in joining, microstructural modifications to minimize isotropy effects, and environmental lifetime modeling, in terms that can be readily assessed by potential users of oxide dispersion-strengthened (ODS) alloys. A report has been prepared compiling results from the literature of ODS alloy joining tr...
