In order to investigate effects of Azomite application in reducing salinity stress in basil herb, a pot factorial experiment based on completely randomized design with three replications was conducted in the research greenhouse of Agriculture Faculty, Ferdowsi University of Mashhad. Treatments were consisted of salinity stress at three levels (0, 50 and 100 mM) as the first factor and the appli...
Evidence of several psychological consequences due to know the disease, intensity, and the medicament future. This disease as a one of the problem criteria of femininity can cause high stress. In this study 116 persons (85 patients and 31 non patients) were investigated. In a prospective way, self-control scale, perceived stress scale, general health questioner were administered and the results...
Two simple feedback control laws for drag reduction are derived by applying a suboptimal control theory to a turbulent channel flow. These new feedback control laws require pressure or shear-stress information only at the wall, and when applied to a turbulent channel flow at Reτ = 110, they result in 16–22% reduction in the skin-friction drag. More practical control laws requiring only the loca...
Background and Objectives: Studies of the relationship between personal qualities and job consequences usually find poor and inconsistent correlations. It is suggested that the reason may lie in ignorance of some modifying factors mediating such relationship. The perceived control has attracted much attention as a candidate factor. This study aimed to examine the mediating role of the perceived...
Objective: The birth of a premature infant and hospitalization in the intensive care unit causes the emergence of many crises and stresses for mothers. In this respect, narrative writing is as a method of counseling to reduce motherschr('39') stress. Therefore, this study was conducted with the aim of the effect of mother’s narrative writing on the stress of mothers of premature infants admitte...
Background and aims: Heat stress is one of the most important occupational hazards that threaten the health of employees in many workplaces. This hazard is more important in the industries with hot processes, such as rubber industry. Therefore, control of this harmful agent is one of the essential measures and priorities of manager in these industries. The purpose of this study was to identifyi...
drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...
Objective(s): Cholecystokinin (CCK) has been proposed as a mediator in stress. However, it is still not fully documented what are its effects. We aimed to evaluate the effects of systemic administration of CCK exactly before induction of stress on spatial memory and synaptic plasticity at CA1 in rats. Materials and Methods: Male Wistar rats were divided into 4 groups: the control, the control-C...
Abstract Background: Stress gradually suppresses the immune system making the body susceptible to various diseases. The aim of this study was to show the effects of cold and immobilization stress on growth of malignant cells in Balb/c mice. Methods: In an experimental study which was carried out in the Molecular & Cellular Research Center of Shahrekord University of Medical Sciences in 200...
Water deficiency is an important factor for plant growth in arid environments. Foliar application of methanol in C3 plants is believed to be more important in water stress tolerance. In order to evaluate the effects of foliar application of methanol on photosynthetic features, chlorophyll fluorescence and chlorophyll content of lentil under water deficit stress, a factorial experiment in comple...
