Influence of bed clusters and size gradation on operational time distribution for non‐uniform bed‐load transport

Piezoelectric bedload impact sensor (PBIS) for particle size distribution

Exponential Formula for Bedload Transport

An exponential formula that does not involve the concept of the critical shear stress is derived in this study for computing bedload transport rates. The formula represents well various experimental data sets ranging from the weak transport to high shear conditions. Comparisons of the present study are also made with many previous bedload formulas commonly cited in the literature.

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

the influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes

the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...

Influence of nonuniform activity distribution on cellular dosimetry.

Dosimetry of nonuniformly distributed 210Po,67Cu, and 123I was evaluated for a single cell, modeled as a homogeneous unity-density sphere with a radius of 7.7 mum, which is typical of a B-cell lymphoma cell. A Visual Basic program was used to calculate S factors and radial absorbed dose-rate profiles for these radionuclides, taking into account their individual radiation energy spectra. The res...
