Monitoring Cellular Mechanical Stress
Science's STKE, 2007Cells exert and respond to mechanical forces, but investigating how these signals are transduced is a challenge. By measuring differential labeling of cysteines in stressed and relaxed cells, Johnson et al . identify proteins that change their structure in response to stress. Using mass spectroscopy, they determined

microRNAs and Mechanical Stress
2011Mechanical stress, one of the major abiotic stresses, significantly affects plant growth, survival, and reproduction. Recent studies showed that cytoplasmic calcium, reactive oxygen species, and phytohormones play important roles in mechanosensing and subsequent anatomical and morphological changes in plants exposed to mechanical stress. A large number

Fracture mechanics stress analysis
1983In this chapter the boundary integral equation (BIE) method is discussed with particular reference to its application to fracture mechanics stress analysis. Although the BIE method has been used to treat a variety of boundary value problems, those encountered in fracture mechanics possess certain unique features which require special treatment.

Transistors under stress: Mechanical stress affects amplification
2002Practically every modern Intel Pentium processor main board features a temperature sensor developed at Delft University of Technology. The sensor detects when the processor starts to become too hot, and switches on a fan to cool it down. As soon as the temperature drops to an acceptable level, the fan is switched off.
