population’s exponential growth along with drought has increased water resources limitation, especially in arid and semi-arid area. therefore, the use of non-conventional water is an important tool for water resource management. if unconventional water has no negative impact on soil properties and water, it can be used for irrigation coupled with desertification projects. so, this paper tries t...

this document provides feasibility study of using treated domestic wastewater in concrete mixing. today, concrete is one of the most important construction materials. from first time that concert was used in construction materials, always the drinkable water used for concrete mixing water. domestic wastewater contains about 400 ppm of organic materials. after the treatment of wastewater, concen...

background: chronic arsenic toxicity (arsenicosis) due to drinking of arsenic contaminated ground water is a global problem. however, its treatment is unsatisfactory. methylation of arsenic facilitates its urinary excretion. persons with relatively lower proportion of urinary dimethyl arsenic acid (dma) are found to have at greater risk of developing symptoms of arsenicosis including its compli...

The availability of multiple sources of food and drink has a profound influence on choice behavior in rodents. It is not known how other taxa might respond to the same kind of variation in availability. We tested European starlings (Sturnus vulgaris) with various combinations of unadulterated and repellent-treated (0.025% citronellyl acetate) resources. In Experiment 1, birds drank more plain t...

Background: Long-term glucocorticoid therapy causes secondary osteoporosis leading to pathological fractures. Glucocorticoid action in bone is dependant upon the activity of 11β-hydroxysteroid dehydrogenase type 1 enzyme (11β-HSD1). Piper sarmentosum is a local herb that possesses the ability to inhibit 11-βHSD1 enzyme activity. We aimed to determine the effects of Piper sarmentosum wat...

the effect of hot water treatments [45°c for five minutes, 55°c for 25 seconds and non-treated(control)], salicylic acid in three levels (0, 1 and 2 mm) and calcium chloride in two levels (2% and 4%) on quantitative and qualitative parameters and storage life of pomegranate cv. meykhosh were investigated. experiment was conducted as a factorial based on completely randomized design with three r...
