We used DNA macroarray and proteome analysis to analyze the regulatory networks in Bacillus subtilis that are affected by disulfide stress. To induce disulfide stress, we used the specific thiol oxidant diamide. After addition of 1 mM diamide to an exponentially growing culture, cell growth stopped until the medium was cleared of diamide. Global analysis of the mRNA expression pattern during gr...

We have found that genomic diversity is generally positively correlated with abiotic and biotic stress levels (1-3). However, beyond a high-threshold level of stress, the diversity declines to a few adapted genotypes. The Dead Sea is the harshest planetary hypersaline environment (340 g.liter-1 total dissolved salts, approximately 10 times sea water). Hence, the Dead Sea is an excellent natural...

water deficit is a major factor influencing yield of canola (brassica napus l.) seed yield and oil content. a field experiment was conducted during 2010 growing season in the agriculture research station of torogh, mashhad, iran to evaluate responses of canola cultivars to limited water. experimental design was rcbd pattern with three replications. treatments were two irrigation regimes (based ...

We investigated the possibility of controlling thin film buckling patterns by varying the substrate curvature and the stress induced therein upon cooling. The numerical and experimental studies are based on a spherical Ag core/SiO(2) shell system. For Ag substrates with a relatively larger curvature, the dentlike triangular buckling pattern comes out when the film nominal stress exceeds a criti...

The present paper investigated the event-related brain potential correlates of the processing of word stress related acoustic changes. We studied the processing of non-speech stimuli containing similar intensity and f0 changes as speech stimuli in a passive oddball paradigm. Contrary to our previous results using speech stimuli with a trochaic stress pattern contrasted with a iambic stress patt...

BACKGROUND Medical students undergo significant stress during training which may lead to own suffering or problem in patient care. High level of burnouts and depression is also not uncommon. The transition from preclinical to clinical training has been regarded as crucial to student in relation to the stress. METHODOLOGY An assessment of perceived stress and its relation to general psychopath...

Cold roller bending is commonly used for bending straight members with hot rolled wide-flange sections to create arches. This process induces plastic deformations along the member, so that it can acquire the desired curvature. The resulting residual stress distribution is different from the wellknown residual stress pattern due to hot rolling. Extensive studies have shown that the influence of ...

The 1999 M 7.1 Hector Mine earthquake ruptured a complex fault system with a branched structure in the north. This fault geometry and slip pattern presents a puzzle, because the northwest branch of this system should be in the stress shadow of the north branch, upon which nucleation likely took place. Through 3D dynamic models of this event, we show that the ability of rupture to propagate to t...

This paper offers a contribution towards the prosodic interpretation of segmental sequences. Focus will be given to consonantal sequences where epenthesis may optionally occur in Brazilian Portuguese, as in o[bs]truir or o[bis]truir “to obstruct”. We will show that some consonantal sequences have distinct representations from others, being that the difference in representation has an impact on ...

Infants develop different kinds of long-term linguistic representation as early as in their first year of life. We examined the interaction of early lexical access and prosodic processing. It is proposed that familiar word forms are stored in a protolexicon before linking any concepts to them, enabling early (proto)lexical segmentation from fluent speech. Additionally, previous results strength...
