Sediment load estimation is one of the most important issues in rivers & dam reservoirs management and generally in water projects. Various empirical equations show that proper analytical or empirical method is not suggested for correct estimation of suspended sediment, yet. In the present study, to assessment of closer estimation to actual data of transported sediment in Ghoran Talar station l...
There are limited data regarding intermediate-term outcomes in patients with persistent BK viremia. Other viral infections have been implicated in the development of allosensitization through heterologous immunity, but the relationship between BK viremia and donor-specific antibodies (DSAs) is unexplored. In 2008, we initiated routine post-transplant BK viremia and DSA screening at our center; ...
the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
Introduction: In radiotherapy treatment planning system (TPS), basic input is the data from computed tomography (CT) scan, which takes into account the effect of inhomogeneities in dose calculations. Measurement of CT numbers may be affected by scanner-specific parameters. Therefore, it is important to verify the effect of different CT scanning protocols on Hounsfield unit (HU) and its impact o...
by far, different models for determining the relationship between the flow rate and amount of precipitation have been developed. many models are based on regression models with limited assumptions. one of the most common methods for estimating sediment of rivers is sediment rating curve. for better estimation of the amount of sediment based of sediment curve rating equation, it is possible t...
ABSTRACT Understanding the hydrosedimentological dynamics of tropical rivers is a challenge in Amazon due to its remote and difficult-to-access areas. This study was based on data collected from 16 control sections 6 subbasins that make up Itacaiúnas River Watershed (IRW), with 4 annual campaigns (high water levels, rising falling low levels) between 2015 2019, aim constructing comparing sedime...
For sediment yield estimation, intermittent measurements of suspended sediment concentration (SSC) have to be interpolated to derive a continuous sedigraph. Traditionally, sediment rating curves (SRCs) based on univariate linear regression of discharge and SSC (or the logarithms thereof) are used but alternative approaches (e.g. fuzzy logic, artificial neural networks, etc.) exist. This paper p...
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 ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
