Subsurface-tile drainage is designed to remove gravitational water and soluble salts from the soil-root zone. However, soil swelling, as influenced by soil Na and electrical conductivity (EC), will reduce saturated hydraulic conductivity. The objective of this research was to determine the influence of Na and EC on the amount of water retained at field capacity (33 kPa), in northern Great Plain...

ground water samples from different upazilas of sunamganj district have been analyzed for drinking and irrigation purposes. correlation coefficients among different parameters were determined. an attempt has been made to develop linear regression equations to predict the concentration of water quality constituents having significant correlation coefficients with electrical conductivity (ec). ca...

Shortened telomere length may cause chromosomal instability in Barrett's esophagus and thus promote tumorigenesis. However, whether short telomere length in all chromosomes or just some of them is associated with increased esophageal cancer (EC) risk is largely unknown. To address this question, we examined the overall and chromosome-specific telomere lengths of 17p, 12q, 2p, and 11q and assess...

In this study, the efficiency of household reverse-osmosis system (HROS) with and without neutralizer accessory was investigated in both real and synthetic samples. The real samples were collected from rural and urban public drinking-water systems with and without primary refinery treatment. The selected areas were situated in the Kurdistan province, Iran. The HROS model RO100GPD with and witho...

A balance between production and degradation of reactive oxygen species (ROS) is critical for maintaining cellular homeostasis. Increased levels of ROS during oxidative stress are associated with disease conditions. Antioxidant enzymes, such as extracellular superoxide dismutase (EC-SOD), in the extracellular matrix (ECM) neutralize the toxicity of superoxide. Recent studies have emphasized the...

in this study, the pattern of changes in the values of soil electrical conductivity (ec) and soil temperature (t) under full irrigation treatment (fi) as compared with prd75 and prd55 treatments (partial root-zone drying which received 75 % and 55% water of fi at each irrigation event) was investigated in 1389 on a maize filed in sari university of agricultural sciences and natural resources. r...

in this research,the effect of power ultrasound (20 khz ,800 and 1000w) at 20.40 and 60 minutes on physico-chemical properties of two rice varieties tarom and neda was investigated and by the soaking method in controlled temperature (47°c) compared.results showed the maximum amount of water absorption of rice, observed at 60 minutes ultrasound treatment (1000w) and the lowest was observed in co...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...

Selecting and cultivating the crops/varieties that can tolerate water salinity is potentially animportant strategy to save fresh water resources and maximize the crop yield in salt affected areas.To evaluate the responses of 36 sorghum lines and cultivars to salinity stress, two fieldexperiments were conducted in non-stress (EC=2 dS/m) and salinity stress conditions (EC=12dS/m) using randomized...

in order to study the effect of irrigation water salinity on quality and quantity of sugar beet (beta vulgaris) at four growth stages, an experiment was conducted in rudasht salinity and drainage research center from 2004-2006. in this experiment, 11 different water salinity treatments and three sugar beet cultivars (ic, 7233 & 7233-p29*msc2) were considered using split plot design based on ran...
