The water content of human stratum corneum has been measured gravimetrically in vitro in relation to relative humidity (RH) and temperature. Water content increased with increasing RH. Stratum corneum water content increased 50% when the temperature was raised from 20 to 35 degrees C at RH below 60%. Temperature dependence decreased with increasing RH until there was essentially no temperature ...

the superabsorbent polymer withholding water and disperse it gradually to roots increase soil water capacity. to study the effect of superabsorbent polymer on decreasing water stress effect as well as increasing irrigation efficiency a factorial experiment based on randomized block design with 4 replicates was design. treatments were 0, 10 and 20 % v superabsorbent and irrigation levels 25, 50 ...

The effects of irrigation, dry farming and drought treatments on the activities of antioxidant enzymes including superoxide dismutase, ascorbate peroxidase, catalase and peroxidase in barley leaves at different generative growth stages under field conditions were investigated. Three senescence parameters including chlorophyll, total soluble protein and rubisco large subunit protein loss, were a...

Background and purpose: Monitoring quality of rivers water and awareness of its health status over time and identifying vulnerable zones are considered as essential steps towards sustainable development and efficient management of the environment. This study used multivariate statistical methods for analyzing water quality and awareness of rivers state in the Mazandaran province, Iran. Materia...

Experiments have been carried out to study the influence of moisture condition, including moisture content and its distribution, on the chloride diffusion in partially saturated ordinary Portland cement mortar. The mortar samples with water-to-cement (w/c) ratios of 0.4, 0.5 and 0.6, cured for one year, were preconditioned to uniform water saturations ranging from 18% to 100%. The interior rela...

Relative water content may be accurately estimated using the ratio of tissue fresh weight to tissue turgid weight, termed here relative tissue weight. That relative water content and relative tissue weight are linearly related is demonstrated algebraically. The mean value of r(2) for grapevine (Vitis vinifera L. cv. Shiraz) leaf tissue over eight separate sampling occasions was 0.993. Similarly...

Drought has adverse effects on plant growth and production. Plants respond to drought stress through biochemical and physiological processes. In the present study, physiological responses of two cumin (Cuminum cyminum L.) ecotypes including Ravar and Gonbad, which belong to dry and sub-humid regions of Iran, respectively, were evaluated in a split-plot factorial experiment with three replicatio...
