Research on Relationship between Residual Environmental Stress and Latent Environmental Stress-I : Estimation of Residual Environmental Stress in Straight Waterway

Relationship between Coverage and Surface Residual Stress

Controlled, uniform, peening has been used to impose precise cov onto mild steel plate specimens. This was achieved by using an the specimens under a single, precision-loaded, 2mm diameter studies have revealed a surprising relationship between percent surface residual stress. Stress increases almost linearly with low coverages but reaches a maximum at about 80% coverage. At 100% coverage the i...

Stress , Environmental

Acute An exposure to an environmental stress that is brief in relation to the temporal scale of the biological system exposed. Biosphere All the plants and animals on Earth, together with the habitat they need for long-term survival. Biotic impoverishment The decline of a species to the point of having little or no ecological significance. Chronic An exposure to an environmental stress that is ...

Oxidative Stress – Environmental Induction

Dietary antioxidants and environmental stress.

Air is one of our most important natural resources; however, it is also in the front line for receiving environmental pollution. Air quality decreased markedly following the industrial revolution, but it was not until the great London Smog in 1952 that air quality made it onto the political agenda. The introduction of the Clean Air Act in 1956 led to dramatic decreases in black smoke and SO2 co...

Environmental stress and flowering time

After the f loral transition the shoot apical meristem (SAM) changes its identity switching from vegetative to reproductive. In annual Arabidopsis ecotypes, the transition to f lowering is strongly promoted by variations in day length (photoperiod). The photoperiodic pathway promotes f lowering when Arabidopsis plants are exposed to long days (LDs) conditions (typical of spring and summer). Pho...
