introduction earth has ever been exposed to environmental hazards. the hazards are continually occurring in the world in the recent years. among them, atmospheric elements have created many human and financial losses in different regions. one of the hazards is dust events and in its severe case is dust storm. it happens more frequently in arid and semiarid regions in deserts and their surroundi...

gypsum found in the soil beneath the foundation of structures, specially hydraulic structures, can cause serious damage to them. the mechanical behavior of gypsiferous soils has not so far been investigated in detail except for the works of petrukhin (1993). here, it has been tried to investigate the mechanical behavior and the effect of soil being leached on settlement and strength of these ki...

the aim of this research was to evaluate the effect of one session of exhaustive exercise with low intensity (55-65% vo2max), moderate intensity (65-75% vo2max) and high intensity (75-85% vo2max) on adiponectin in active women. for this purpose, 30 healthy women (mean age 21.6 years, weigh 59.7+3.35 kg, vo2max 39.1+0.58 ml/kg/min, no history of cardiovascular diseases and diabetes) were selecte...

in the water-limited areas, the great challenge of the agricultural sector is more production from less water that it can be achieved by increasing water productivity. a field study was conducted to compare various cultivars of wheat to water using line source sprinkler irrigation at gorgan research station in 2005-2006. the effect of variable water supply on yield and wue of six wheat cultivar...

global warming and climate change have drawn special attention to soil and its potential for stable carbon sequestration. soils are the largest stores of carbon in terrestrial carbon cycle and contain about three times more carbon than vegetation cover and two times more than that of atmosphere. studying the effects of grazing on soil carbon storage is important because of the major role soil o...

stevia rebaudiana bertoni is a medicinal, perennial and herbaceous plant from asteraceae family with sweet glycosides in its leaves. salinity stress is one of the important limiters in agricultural productions. salinity influences the growth and development of plant by effect on more activities in physiological and morphological characteristics. to study the effect of salinity on morphological ...

diabetes is a metabolic disorder specified by hyperglycemia following a defect in insulin secretion, insulin resistance or both. the aim of this study was to examine the effect of high-intensity interval training (hiit) on serum adiponectin levels and insulin resistance of women with type 2 diabetes. for this purpose, 35 overweight women with type 2 diabetes (age range 45-60 years, bmi 25-30 kg...

the intensive use of antimicrobial agents worldwide for prophylactic and therapeutic purposes has been associated with increase of bacterial resistance in the exposed microbial environment. oxytetracycline is the most frequently used antibacterial in the cold water fish industry because of its broad spectrum of activity and low cost. aeromonas hydrophila and other motile aeromonads are among th...

background and objectives: the region of the experiment is located in golestan province, iran, with agriculture subject to various farming conditions (rain-fed and irrigation) and different levels of salinity (more than 38% of golestan’s total land area is salt-affected). the purpose of this study has been to evaluate the stress indices in the selection of tolerant wheat genotypes, not only for...
