Canola (Brassica napus L.) as one of the oilseed crops has recently received lots of attention due to its suitable oil quality and high oil percentage. To evaluate the effect of water deficit stress on canola genotypes with regard to yield, drought tolerance quantitative indices and identify drought tolerant genotypes, an experiment was conducted in research farm of seed and plant improvement I...

objective: this study aimed to investigate the prediction of asthma control on the basis of perceived stress, locus of control, and self-efficacy in adult patients with asthma. methods: this was a descriptive-correlative and cross-sectional study.the solecty of this study is all asthmatic patients in tehran. our sample consisted of 100 participants who were selected by purposeful sampling meth...
Research literature has suggested that mindfulness affects stress that an analytical study of this effect can be useful in preventing stress. In recent years, the third wave of cognitive-behavioral and paradigmatic interventions, known as mindfulness, has attracted many researchers' attention. Therefore, this study aimed to investigate, systematic review, and meta-analysis about the effect of m...
Stress is a type of person-environment relationship which is appraised by the individual as stressful or beyond one’s own resources and, as a results, threatens the individual’s wellbeing and welfare. The aim of the present study was to investigate the variables of resilience, coping strategies, and social support as predictors of vulnerability to stress among students. The participants consist...

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...
This article demonstrates a new approach for nonlinear finite element analysis. The methodology is very suitable and gives very accurate results in linear as well as in nonlinear range of the material behavior. Proposed methodology can be regarded as stress based finite element analysis as it is required to define the stress distribution within the structural body with structural idealization a...
