Drought stress is one of the serious problems that restricted agronomic plant production worldwide. In molecular level, the harmful effect of drought stress is mostly caused by producing of large amount of reactive oxygen species (ROS). Catalase and Metallothionein genes have a crucial role to mope the hydrogen peroxide (H2O2) resulting reducing oxidative damage. In this research the gene expre...
Repeated stress can trigger a range of psychiatric disorders, including anxiety. The propensity to develop abnormal behaviors after repeated stress is related to the severity, frequency and number of stressors. However, the pattern of stress exposure may contribute to the impact of stress. In addition, the anxiogenic nature of repeated stress exposure can be moderated by the degree of coping th...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
In this study, ANSYS finite element software is used to simulate the temperature and stress field in the laser powder deposition process. The model is used to determine the effect of the deposition pattern on the final stress distribution. Four deposition patterns are defined to cover the same area: long bead, short bead, spiral in, and spiral out. The results show that the deposition pattern s...
deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...
THE PELVIC RING IS STRESSED BY EXTERNAL FORCES by partial body weight, by ligament tension, and by muscles forces stabilizing the hip joints. For the symphysis ossis pubis there exist data concerning the type and magnitude of stresses. In one-leg-standing pressure, shear forces are predominant, and in both-leg-standing tensile forces are acting on the pelvic ring. Rupture of the symphysis is pr...
PURPOSE To investigate the impact of colored overlays on the accommodative response of individuals, with and without pattern-related visual stress (PRVS), a condition in which individuals manifest symptoms of perceptual distortion and discomfort when viewing a 3-cyc/deg square-wave grating. METHODS Under double-masked conditions, 11 individuals who reported PRVS selected an overlay with a col...
The relationship between tone pattern and word stress is investigated on different aspects. The distribution of the original tones of the unstressed syllables in disyllabic words, the perception of word stress in utterances and the allocation of sentence stresses within words are analyzed. The results of the analyses coincide quite well, indicating that tone has something to do with the engende...
saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...
