Because of slight variation of the static head due to discharge fluctuations, the labyrinth weirs are considered to be economical structures for flood control and water level regulation in irrigation networks, as compared to other devices. Labyrinth weirs are composed of folded sections observed as trapezoidal and triangular in plan view. In this study, rectangular and U-shaped labyrinth weirs ...

BACKGROUND Parasitic infections, which are among the most common infections worldwide, disproportionately affect children; however, little is known about the impact of parasitic disease on growth in very early childhood. Our objective was to document the prevalence of parasitic infections and examine their association with growth during the first three years of life among children in coastal Ke...
objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...
Introduction: The findings of cephalometry studies are widely applied in medical and engineering fields. Cephalometry measurements are affected by genetics‚ age‚ gender‚ and social‚ economic and geographic factors.This study assesses cephalometry of the neurocranium in male newborns in Kermanshah,Iran by an anthropometry method to confirm or reject the theory of brachycephalization (i.e., ...
Populations of wild barley, H. spontaneum Koch., were collected in two countries, Israel and Turkmenistan, in environments representing two similar sharp clines of aridity. This allowed us to use the same criteria to define species core and periphery in two regions. Plants from 10 Israeli and 19 Turkmenian populations were grown in a field trial with three water treatments and compared for amou...
Parental lines, namely: F1, F2, BC1, BC2, BC11, BC12, BC21, BC22, BC1 selfed, and BC2 selfed generations of three crosses involving six cultivars of durum wheat (Triticum durum Desf.) were studied for awn length under normaland late-sown environments to analyze the nature of gene effects and components of heterosis (over the better parent). A sixparameter model in the cross Cocorit 71 x A-9-30-...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
We construct a class of nonnegative martingale processes that oscillate indefinitely with high probability. For these processes, we state a uniform rate of the number of oscillations for a given magnitude and show that this rate is asymptotically close to the theoretical upper bound. These bounds on probability and expectation of the number of upcrossings are compared to classical bounds from t...
