Fresh water fish, Heteropneustes fossilis were subjected to 5.76 μg/L (0.8 of 96 h 50% lethal concentration, LC50) and 1.44 μg/L (0.2 of 96 h LC50) solution of cypermethrin for short-term (96 h) and long-term (28 days), respectively. After short-term cypermethrin exposure, the plasma calcium levels of Heteropneustes fossilis showed a decrease which persisted for 96 h. In long-term exposed fish,...

intercropping is considered as a method for increasing yield per unit and stability. in order to evaluate the effects of phosphorous biofertilizer and chemical phosphorous on fodder quality of corn (zea mays l.) and grass pea (lathyrus sativa l.) intercropping, two field experiments were conducted as factorial based on randomized complete block design with four replications at two places simult...

Aedes aegypti (L.) is known as vector of dengue and chikungunya fever. Larvicides are used to control this vector. We evaluated the efficacy of newly developed formulations of larvicides to control Ae. aegypti under field conditions for 24 weeks post single application. Mosdop P and Mosdop TB containing diflubenzuron (2% and 40 mg/tablet, respectively) as the active ingredient, were applied at ...

the effect of levels of nitrogen on growth and nitrogen uptake patterns and grain protein quality of grain sorghum was investigated by two experiments which were conducted at pakdasht-tehran in 2003. in a completely randomized design with three replications, grain sorghum (sorghum bicolor (l.) moench) hybrid h-726 was grown under greenhouse conditions using water culture technique. the first ex...

Drought is a key abiotic stress that confines agriculture development worldwide. Silicon (Si) commonly considered to be valuable element for resistance against drought and sustainable agriculture. To investigate the morpho-physiological biochemical characteristics of Gerbera jamesonii plants, pot experiment was conducted under greenhouse conditions exposed water (60% FC) well-watered (100% cond...

The use of population-level indices to estimate individual exposures is an important limitation of previous epidemiologic studies of disinfection by-products (DBPs). We examined exposure misclassification resulting from the use of system average DBP concentrations to estimate individual-level exposures. Data were simulated (n=1000 iterations) for 100 subjects across 10 water systems based on th...

OBJECTIVE To study the relationship of fat mass, extracellular-to-intracellular-water ratio, and bone mineral density with growth hormone function and physical activity in Prader-Willi syndrome. STUDY DESIGN There were 17 patients with PWS (10 women, ages 7.5-19.8 years) and 17 obese control patients, matched for gender and bone age. FM and extracellular-to-intracellular-water ratio were meas...

Carnation (Dianthus caryophyllus L.) is valuable in terms of production and exports in the world. Increased vase life of cut flowers is an important factor for their market acceptability. For this purpose this study was carried out to examine the effect of plant essential oils as compared to 8-hydroxy-quinoline sulfate on the control of bacteria population and the longevity of carnation cut flo...
