The patient was in New York Heart Association Functional Classification (NYHA FC) Class IV. Severe aortic stenosis, EF 20%, Left ventricular end-systolic diameter 65 mm, end-diastolic diameter 50mm, global hypokinesia, gradient 51/13...

Inconel 718 nickel-based superalloy has superior thermal and mechanical properties. Nevertheless, it is a hard-to-machine material, the heat generated by processing excessive. Reasonable cooling lubrication (CL) methods have essential effects on its cutting performance surface integrity. In this study, Dry (DC), flood (FC), cryogenic (CC), minimum quantity (CMQLC), are used to under same parame...

The purpose of the present study was to investigate the effect of plant growth-promoting rhizobacteria(PGPR) on physiological and biochemical properties of maize (Zea mays L.) in different cultivation methods under water stress. The experiment was carried out as split-plot design including water stress (well-watered, mild stress, and severe stress) as main plot and also cultiv...

background and objectives: febrile convulsion (fc) is the most common seizure disorder in childhood period. some studies have suggested association between seasons and occurrence of fc. this study was designed to determine demographic features, causes and seasonal variations in cases with fc. method: in this descriptive, cross sectional study, 282 children 6- 60 months with fc were admitted to ...

in order to evaluate the utilization ability of drought resistance indices such as: yield index (yi), yield stability index (ysi), stress susceptibility index (ssi), tolerance (tol), mean productivity (mp), geometric mean productivity (gmp) and stress tolerance index (sti) in sunflower hybrids, three separate experiments were conducted as randomized complete block design at the research field o...

background & aim: drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. in this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. experimental: this study was done in an experimental greenhouse, i.a.u., shahrekord branch, iran at...

this research was conducted to evaluate the effect of mild and intense drought stresses on root traits and some anti-oxidative enzymes and to identify drought tolerant genotypes in tall fescue. twenty-four genotypes were assessed under three levels of moisture regime (control, mild and intense drought stresses) according to a factorial experiment based on a completely randomized design with thr...

Background: Essential oil content and composition in medicinal and aromatic plants is highly affected by both biotic and abiotic factors. Objective: To investigate the effects of drought stress, zeolite and bio-fertilizers on morphological characteristics and essential oil constituents in Dracocephalum moldavica L. Methods: This experiment was conducted in the form of split factorial based on...

background: occupational stress has physical and psychological consequences, and is a major cause of job dissatisfaction among employees, which can reduce the quality of services provided. this study was conducted to examine the relationship between job stress and the prevalence of musculoskeletal disorders (msds) among computer users in hospitals (private & governmental) of gorgan, iran, in 20...
