in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
in this paper, we study b-focal curves of biharmonic b -general helices according to bishop frame in the heisenberg group heis finally, we characterize the b-focal curves of biharmonic b- general helices in terms of bishop frame in the heisenberg group heis
BACKGROUND We aimed to evaluate the efficacy and safety of dinoprostone for cervical ripening and labor induction in patients with term oligohydramnios and Bishop score ≤ 5. METHODS This was a prospective case-control study, which included 104 consecutive women with a Bishop score≤5. Participants were divided into two groups. Women with term isolated oligohydramnios and Bishop score≤5 underwe...
abstract this study is an attempt to determine the effect of nano- technology education on science lesson for fifth grade in primary school in the city of kermanshah. this research is experimental and is conducted in the from of pre-test and post- test for the control group. an achievement test was administered to determine the rate of learning in the students. the research is an applied one. ...
The objective of the study in this paper is to define M₁,M₂-direction curves and M₁,M₂-donor curves of the spacelike curve γ via the Bishop frame of type-2 in E₁³. We obtained the necessary and sufficient conditions when the associated curves to be slant helices and general helices via the Bishop frame of type-2 in E₁³. After defining the spherical indicatrices of the associated curves, we obta...
background: an increasing success in induction of labor and subsequent termination of pregnancy in presence of unfavorable cervix requires cervical ripening in order to reduce complications and to diminish the rate of cesarean sections as well as the duration of labor. however, there is no consensus on the efficiency of conventional methods for cervical ripening. objective: to determine and ...
چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...
