the present study investigates the effect of different exposure densities on third grade iranian junior high school (ijhs) students’ efl development and retention. it also attempts to explore whether there is any differential performance due to type of post-exposure assessment tasks (recognition vs. written production). performances of five groups of learners receiving equal amount of exposure ...

The study was conducted to determine the effect of dietary energy on milk yield and its composition under the influence of bovine somatotropic (bST) hormone in Nili Ravi buffaloes. Multiparous buffaloes (n=12) at mid lactation and similar level of production were selected and randomly divided into three groups (A, B and C) with four animals in each group in a completely randomized design. All t...

background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

striped rice stem borer, chilo suppressalis (lepidoptera: pyralidae) is one of the major pests in north part of iran which causes serious damage. the last larval instar overwinters in the stem of weeds around the fields. regarding the importance of weeds as overwintering habitat, population density of larvae was studied in three areas; low-, mid-, and up-lands of mazandaran province and also on...

INTRODUCTION Lead exposure in children remains a significant public health issue, although many advances have been made. The Mid-Appalachia area (Kentucky, New York, Ohio, Pennsylvania, and West Virginia) is 89-91% rural with a population density of 16-21 people/km2 (41-54 people/mi2). Mid-Appalachia has significant health disparities including concerns for the consequences of greater lead expo...

backgrounds and aims: semi automated processes of iranian tire manufacturing factories lead to significant occupational exposures to benzene and toluene compounds. this study was conducted to evaluate the magnitude and risk of workers exposures. materials and methods: personal monitoring of 100 workers (10 groups) was performed using niosh method no.1501 in two tire manufacturing factories in t...

We calculate the spectral function A ρ of the ρ meson in nuclear matter. The calculation is performed in the low density approximation , where the in-medium self energy Σ med is completely determined by the vacuum ρ N forward scattering amplitude. This amplitude is derived from a relativistic resonance model. In comparison to previous non-relativistic calculations we find a much weaker momentum...
