Response to stress is an important health risk factor. We compared several methods based on automatic speech analysis for extracting prosodic information from spontaneous speech of 19 subjects participating in a study of the effects of bupropion (a medication that increases smoking cessation rates and treats depression) on stress response in smokers. Automatically extracted mean fundamental fre...

The topic of this thesis is the investigation of the local states of stress resulting from the introduction of a v-notch in a coaxial circle on the pressurized surface of a circumferentially clamped plate subject to axisymmetric loading. The understanding of the fracture behavior of a component experiencing such a condition is of particular interest to the aerospace and defense industries where...

Rolling contact fatigue tests on 100Cr6 steel were carried out with a ballon-rod tester. Microstructural damage was manifested by gradual hardness changes under the subsurface, and microcracks formed adjacent to inclusions; both being evidence of plastic deformation. The hardness increase appears to be due to the development of residual stress, while the microcracks form as a result of the conc...

four rapeseed cultivars (hayola 401, hayola 308, rgs and option) were evaluated for some physiological traits under stress (50 % field capacity (fc) and non-stress (irrigated) conditions. the factorial set of treatments was arranged within a randomized complete block design with three replications. the collected data were analyzed using path and factor analyses. these is results showed that bas...

This study was carried out to investigate the effects of foliar spray of salicylic acid and ascorbic acid on some morpho-physiological traits of Pistacia vera cv. Badami-zarand under drought stress. The experiment was conducted during 2017-2018 in the greenhouse condition, in a factorial randomized complete block design with three replications on pot plants. The soil texture of experim...

In structures, stress concentration is a factor of fatigue fracture. Basically, the stress concentration is a phenomenon that should be avoided. However, it is difficult to avoid the stress concentration. Therefore, relaxation of the stress concentration is important. The stress concentration arises from notches and circular holes. There is a relaxation method that a composite patch covers a no...

Poplar 69 (Populus deltoides Bartr. cv. ‘Lux’ (I-69/55)) was chosen for a pot experiment to study the growth and extraction of Cd from soil various parts one-year-old trees growing in upright artificial leaning (45°) patterns under different stress. The results indicated considerable tolerance both poplar (UP) (LP) stress soil, though with significant inhibition application. LP demonstrated sig...

background : occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. recently, staff network of different government universities of thailand have called higher education commission, and ministry of education, thailand to resolve the issue of gov-ernment education policy (e.g. wage inequity, poor...
