Transcription of genes coding for formate dehydrogenases (fdh genes) and hydrogenases (hyd genes) in Syntrophobacter fumaroxidans and Methanospirillum hungatei was studied following growth under different conditions. Under all conditions tested, all fdh and hyd genes were transcribed. However, transcription levels of the individual genes varied depending on the substrate and growth conditions. ...

Abstract Jurassic carbonate strata in the eastern Paris Basin exhibit several generations of faults, tension gashes and stylolites. Although their relative chronology can sometimes be determined according to cross-cutting relationships, duration major deformation phases influence on fluid flow cementation are still uncertain. This contribution aims clarify timing brittle associated calcite ceme...

Aim: This study investigated the cultural method and 16S rRNA gene analysis to reveal composition diversity of lactic acid bacteria (LAB) from dairy origin (spontaneous fermented cow milk) in Nigeria.
 Methods: Six samples which includes two raw milk, goat milk (nono) were collected subjected standard microbiological investigation using both molecular methods. The cultured on MRS media, is...

Abstract The diverse activity of flavoenzymes in organic transformations has fascinated researchers for a long time. However, when applied outside an enzyme environment, the isolated flavin cofactor only shows largely reduced activity. This highlights importance embedding reactive isoalloxazine core flavins defined surroundings. latter include crucial non-covalent interactions with amino acid s...

Natural discontinuities as well mechanical properties are the difficult-to-control parameters that significantly influence fragmentation of marble after blasting. In Central Africa, Bidzar quarry is only one producing marble, plagued for decades by block problems, requiring multiple blasts cause huge costs and environmental problems. The objective this study to predict rock improve its geologic...

Aim. To determine the effect of long-term use various systems basic tillage and fertilization on productivity soybean agrocenoses, efficiency its cultivation technologies. The article presents results research influence main soil formation crop indicators economic production in conditions Forest-Steppe Ukraine with aim identifying most effective, adapted to weather that have developed recent ye...

In Cameroon in general and the Highlands of Cameroon particular, there is no fracture map since its realization not easy. The region’s harsh accessibility climatic conditions make it difficult to carry out geological prospecting field missions that require large investments. This study proposes a semi-automatic lineament mapping approach to facilitate elaboration of West Highlands. It use...

Colorectal carcinomas (CRCs) with high-level microsatellite instability (MSI-H) often contain gene fusions, which involve receptor tyrosine kinases. This study included 105 MSI-H CRCs. NTRK1/2/3, ALK, ROS1 and RET fusions were analyzed by PCR test for 5’/3’-end unbalanced expression, is capable of detecting all translocation variants. The type rearrangements was subsequently determined variant-...

Aim. To study the effect of long-term use primary soil treatment and fertilization systems on yield white mustard. The results research impact basic fertilizer economic efficiency mustard production in Forest-Steppe zone Ukraine are presented order to identify most effective, adapted natural climatic conditions recent years. Methods. was conducted during 2018–2021 a stationary two-factor field ...

Banks play an important role in the Iranian economy which has a bank-based financial system. We examined the impact of exchange rate volatility as a determinant of banks' performance. In recent years, the exchange rate has been volatile in the Iranian economy and have an adverse effect on banks' performance. This study, investigate the issue for the period 2007-2017 for 14 Iranian banks. Exchan...
