in order to evaluate the waterlogging stress effects on yield and yield components of rapeseed, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental stage (seedling, stem elongation, flowering and g...

many researchers have been efforted to identify the shape of distribution of stress and strength of castellated beam and base on that, offer a method for design that members. through this methods, comparing virendil method by simplicity and reasonable results, have been used widly. regardless from shortcoming of this method, there is two idea for distribution of stresses via primary bending in ...

Stable stress-responsive models have been established in murine (Moloney) virus sarcomas, which lend themselves to further study of intervening immunological mechanisms. Maximum tumor size was increased in sex-segregated male BALB/c mice at 6 and 9 months of age and in females subjected to 3 days of electric shock stress following virus inoculation. Reduction in maximum tumor size was found in ...

In this study we investigated the effect of jitter and longterm F0 measures on perceived emotional stress using stimuli synthesized with the LPC coefficients of a steady vowel and varying F0-tracks. The original F0 tracks were taken from naturally occurring speech in stressful and not stressful conditions. Stimuli with more jitter were rated as sounding more hoarse but not more stressed. Mean a...

BACKGROUND Although rupture of an atherosclerotic plaque is considered to be the cause of most acute coronary syndromes, the mechanism of plaque rupture is controversial. METHODS AND RESULTS To test the hypothesis that plaque rupture occurs at sites of high circumferential stress in the diseased vessel, the distribution of stress was analyzed in 24 coronary artery lesions. Histological specim...

Abdominal aortic aneurysm (AAA) is a localized enlargement of the aorta, conventionally diagnosed when the maximum anteroposterior vessel diameter exceeds 3.0 cm. AAAs are most prevalent in elderly men and are frequently asymptomatic until point of rupture, which is the catastrophic failure of the aneurysmal wall associated with an overall mortality rate between 65% and 85%. Current management ...

background: the salvage proximal femoral osteotomy is performed in mild or moderate osteoarthritis when the articulating surfaces are normal and relieves the subject’s pain. because the importance of angular mal-alignment of the femur bone at the hip junction accurate pre-op planning based on patient specific anatomy is required to prevent any lower limb misalignment and joint problem pre-opera...

the objective of the present study was to assess the combined effects of drought stress and foliar application of zinc and manganese on seed quality of red bean (naz variety) during the accelerated aging test. the experiment was carried out as split factorial in a randomized complete block design (rcbd) with three replications at the research farm of shahrekord university during 2010-2011. drou...
