The phenomena of stress-induced (or flow-induced, strain-induced, force-induced) crystallization is characterized by the preferential of orientation of polymer segments along the direction of applied force. Many researches report that the drawing and spinning process would increase the crystallinity of polymeric materials, resulting in oriented segments that would explosively improve the crysta...

Exposure of Escherichia coli to nitric oxide (NO) or nitrosating agents causes significant changes in patterns of gene expression. Three recent studies have used microarrays to analyse the response of the E. coli transcriptome to NO and nitrosative stress. Drawing on the array data, I review our current understanding of the E. coli regulatory systems that are involved.

A proximity drawing of a graph is a straight-line drawing where adjacent vertices are represented by points that are deemed to be close according to some proximity measure. A rectangle of innuence drawing is a proximity drawing where the measure is based on the concept of rectangle of innuence. Given two points u and v, the rectangle of innuence of u and v is the axis-aligned rectangle having u...

OBJECTIVE To examine possible relations between parents' psychological stress and children's saliva cortisol levels in connection with a mild stressor (drawing a blood sample). METHOD Parenting stress and serious life events at birth, age 1, age 2, age 5, and age 8 were assessed. Eighty-two paired saliva samples collected from their 8-year-old children just before and 30 min after blood was d...

This paper is referred to the experiences run at Iuav since 2004 in the framework of the EU-FSE founded Courses of Collaborative Composition. In these courses we built up some work/game thought as meaning of a distance collaborative game. Rally around these games, we delivered specific knowledge and portions of technical knowledge referred to the issue of formal structure, shape grammar, and co...

The conditions of modern professional activity special units internal affairs bodies are characterized by a significant intensity mental stress, as well wide variety and heterogeneity circumstances that can lead person into state affect, complete disorientation in the environment. Employees need to assess situation impartially make adequate decisions taking account its unpredictability. In such...

Currently, many researchers pay attention to studying the influence of process variables on quality metal products after manufacture. The most common methods metalworking are forming processes, in which a high degree deformation, uneven plastic and elevated temperatures utilized. In cases manufacturing using these methods, self-balanced system residual stresses is formed that significantly affe...
