Comparative genomics, metagenomics, and single-cell technologies have shown that populations of microbial species encompass assemblages of closely related strains. This raises the question of whether individual bacterial lineages respond to the presence of their close relatives by modifying their gene expression or, instead, whether assemblages simply act as the arithmetic addition of their ind...

The influence of two yeast strains and the addition copper sulphate on aroma Riesling wines was monitored. Two commercially available strains, Zymaflore VL3 X-Pure, were applied. General composition, volatile thiols, norisoprenoids, free terpenes, fermentation, sulphur compounds content determined, sensory attributes assessed by 22 tasters in a balanced incomplete block design (BIBD). produced ...

Fatigue crack growth is usually studied using C(T) or M(T) specimens with through-thickness cracks. The objective of the present study to propose a cylindrical specimen central crack, produced by additive manufacturing. This geometry allows have pure plane strain state along whole front, avoiding complexities associated corner points, shape, and variation closure front. Additionally, this may b...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

Abstract In the paper, we are concerned with nonlinear Cauchy problem on Vlasov–Poisson–Landau/Boltzmann system around global Maxwellians in a torus or finite channel. The main goal is to establish existence and large time behaviour of small amplitude solutions for class low regularity initial data. molecular interaction type restricted case hard potentials two classical collision operators bec...

2-Mercaptobenzothiazole, which is mainly used in the rubber industry as a vulcanization accelerator, is very toxic and is considered to be recalcitrant. We show here for the first time that it can be biotransformed and partially mineralized by a pure-culture bacterial strain of Rhodococcus rhodochrous. Three metabolites, among four detected, were identified.
