Water potential is amongst the most useful parameters for the measurement of the degree of water stress in plants. With the objective of mitigating adverse effects of moisture stress on water potential, osmotic potential and pressure potential of wheat variety Inquilab-91, a greenhouse experiment was conducted using two moisture levels viz., normal moisture supply and moisture stress at crown r...
This paper is devoted to study a problem of plane waves reflection at a traction-free surface of a pre-stressed functionally graded piezoelectric material (FGPM). The effects of initial stress and material gradient on the reflection of plane waves are studied in this paper. Secular equation has been derived analytically for the pre-stressed FGPM half-space and used to show the existence of two ...
Drought stress is a major abiotic constraint limiting crop production world wide. In current study, we investigated the adverse effects of drought stress on growth, yield and endogenous phytohormones of soybean. Polyethylene glycol (PEG) solutions of elevated strength (8% & 16%) were used for drought stress induction. Drought stress period span for two weeks each at pre and post flowering growt...
Cross-amplification of five Arabidopsis abiotic stress-responsive genes (AtPAP, ZFAN, Vn, LC4 and SNS) in Lepidium has been documented in plants raised out of seeds pre-treated with potassium nitrate (KNO 3) for assessment of enhanced drought stress tolerance. cDNA was synthesized from Lepidium plants pre-treated with KNO 3 (0.1% and 0.3%) and exposed to drought conditions (5% and 15% PEG) at s...
Nurses caring for psychiatric patients may have to face violent emotions and unpredictable behaviour which can be quite stressful. A stress management program may equip nurses with skills to cope effectively with the stress. A one group pre-test and post-test design was adopted to test this hypothesis. Both gender nurses caring for psychiatric patients were invited to undergo 10 consecutive, on...
Pre-eclampsia is a disorder characterised by pregnancy-induced hypertension and new-onset proteinuria occurring in the second half of pregnancy. Worldwide, approximately 2-3% of all pregnant women develop pre-eclampsia. The condition is a major cause of maternal and fetal morbidity and mortality. Abnormal placentation is an important predisposing factor for pre-eclampsia, while endothelial acti...
increasing pressure of stressors along with anxiety and depression reduce the human being’s ability to deal with simple issues of life. women who are often facing with stressful situations are more fragile and vulnerable than men. the purpose of the present study was to investigate the effect of sahaja-yoga mindfulness exercises on reducing stress, anxiety and depression in women with stress, a...
Background & Objective: Job burnout is one of the inevitable consequences of occupational stress. Professional staff of social services are the first candidates of burnout, therefore this study was aimed to determine the relationship between occupational stresses with job burnout in pre-hospital emergency staff. Method: In this cross-sectional study, 206 employees, working in 44 pre-hospital ...
Background: Post-Traumatic Stress Disorder is one of the most prevalent post traumatic events. The purpose of this study was to determine the efficacy of compassion therapy in improving the symptoms of post-traumatic stress disorder. Methods: The study population consisted of war veterans with post-traumatic stress disorder referring to Ebnesina Hospital in Mashhad, Iran. 30 individuals of the ...
