the effects of sowing date and crop density of chickpea on population and infestation of pod borers were studied in a randomized complete block design by factorial arrangement with three replications in the chickpea growing region of greet, khorramabad in 2007 until 2009. experimental factors comprised of sowing dates (march 14, march 30, and april 21) and crop density (25, 50 and 75 plant.m-2)...

BACKGROUND Unintended pregnancy is a significant public health concern in the world. Particularly, female sex workers are exposed to the risk of unintended pregnancy, abortion and their consequences. The aim of this study was, therefore, to assess unintended pregnancy and associated factors among female sex workers in Mekelle city, northern Ethiopia. METHODS A community based cross-sectional ...

Congenital hypothyroidism is a preventable cause of mental retardation. Since clinical signs of congenital hypothyroidism do not generally become obvious before three months of age, screening programmes have been introduced in North America and Europe, which consist of T4 or TSH screening on newborn infants on the third day of life. The screening for congenital hypothyroidism was initiated in P...

Estimation of length at maturation and spawning time and determination of fishing prohibition time and optimum length for catch are of important information about a fish species. Seasonal samplings were conducted over a year to study population dynamic of Carasobarbus luteus in Shadegan wetland. Samples were collected from five sampling stations in Shadegan wetland (Salmane, Rogabe, Khoroosi, M...

Mapping complex crossing fibers using diffusion MRI techniques requires adequate angular precision and accuracy. Beyond diffusion tensor imaging (DTI), high angular resolution sampling schemes such as diffusion spectrum imaging (DSI) and q-ball imaging (QBI) were proposed to resolve crossing fibers. These schemes require hundreds of data approximately five to ten times more than DTI, offsetting...

Fertilizer management particularly for mango trees is tedious on alkaline and calcareous soil. Mango (Mangifera indica L.) cv. Langra trees were supplied fertilizer through soil application under bimonthly nutrient application programme to ensure the continuous supply of nutrition to plants throughout the year. Fertilizer (N, P and K) was supplied five times a year at regular intervals while sk...
