aAnother type of stress concentration at the site of two drilled holes located half way between the end supports of a three-point loaded bent beam has been used in the evaluation of metals for oilfield equipment. 在二个被钻的孔的地点的另一种压力集中使一个三点加载弯曲的横梁的支持为油田设备...
second type of bond is termed “flexural Bond stress” and comes into existence in pre-tensioned and bonded,post-tensioned members when the members are subjected to external loads.Flexural bond stress does not exist in unbounded,post-tensioned construction,which accounts for the term “unbounded”....
The optimal designs and statistical inference of accelerated life tests under type-I are studied for constant stress-accelerated life tests (CSALTs). It is assumed that the lifetime at design stress has generalized logistic distribution. The scale parameter of the lifetime distribution at constant ...

In addition, changes in HRV in unrelated diseases such as stroke60, dementia61, mental illness62, renal failure, diabetes, sleep apnea, stress, and pain among others have been observed5,63,64. Noise in the recording, being technical or ectopic beats influence any analysis of the variance in...
We sought to derive sex-specific normal values for LV functional parameters obtained using two quantitative methods.Among 1044 consecutive patients who underwent dipyridamole stress myocardial perfusion-gated 201Tl SPECT in 2008, a total of 140 (56 men) with normal perfusion imaging were selected. ...
Julian D.Ford, ...Christine A.Courtois, inPosttraumatic Stress Disorder (Second Edition), 2015 Dual Conditioning Models. A combination of classical and instrumental conditioning was described by O. H. Mowrer (1947) as a “two factor theory” of learning. Mowrer observed that animals (and humans...

Besides, it also enhances the level of oxidative stress and promotes the production of chemically toxic substances. These substances, upon metabolic activation, can covalently bind to sperm DNA, resulting in the formation of adducts that damage DNA integrity, peroxidize sperm cell membrane lipids, ...
