While we are beginning to appreciate the cellular roles played by long noncoding RNAs, the function of transcripts emerging from repetitive genomic regions remains enigmatic. In this issue, Zovoilis et al. report that the polycomb protein EZH2, upon heat shock, facilitates transcription of stress-responsive genes by inducing the degradation of the transcriptional repressor B2 repeat RNA.

Stress is a physiological reaction to the ever-increasing demands of life. After each stressful event, the body should be returned to a normal relaxed state. However, continuous stress of modern life sometimes put the subjects at risk of developing a range of diseases; from psychosomatic to anxiety disorders. Stress management program gives a range of tools to reduce the impact of stress and pr...

The goal of this study is investigating reduction of residual stresses from welding carbon steel plates through vibrationstress reliefmethod vs. thermal method. In order to carry out the required experimental tests, carbon steel plates were welded together under specific conditions as samples. Some of the samples were vibration stress relieved, some were thermal stress relieved while the rest r...

A finite element model was developed to simulate the vibratory stress relief after welding. Both resonant and nonresonant vibrations can relieve residual stresses in welded structures by creating plastic deformation around the weld area. For the non-resonant vibration, the stress reduction strongly depends on the vibration amplitude. For the resonant vibration, the vibration frequency is the ke...
