the motive behind this study was to evaluate the iranian state university efl entrance examination test (ueeet) based on bachman and palmer’s (1996) ‘usefulness six-faceted model ‘accommodating relia- bility, validity, impact, interactiveness, authenticity, and practicality. to do so, thirty professors and one-hundred efl freshmen were selected randomly from five universities. a questionnaire c...

background: there is not any report on the radiation doses received by patients in diagnostic radiology sections in hospitals under control of chaharmahal and bakhtiari medical sciences university, in the south west of iran. objectives: the aim of this study is measurement of entrance surface doses (esd) for the most routine types of x-ray procedures in radiology centers as part of ongoing dose...

One of the more challenging aspects of hybrid permanent magnet undulator design is end-field termination. Klaus Halbach provided indication of correct excitation patterns for tapered wigglers, but implementation on hybrid undulators has proven more difficult. Initial results on APS undulators achieved complete passive gap dependence of both total residual angle and trajectory through the device...

This paper describes a corpus comprised of university entrance examinations, which is aimed to promote research on NLP-based problem solving. Since entrance examinations are created for quantifying human ability of problem solving, they are a desirable resource for benchmarking NLP-based problem solving systems. However, as entrance examinations involve a variety of subjects and types of questi...

A theoretical analysis has been made to explore thermal entrance region heat transfer in nanofluids. The numerical model used in this paper is based on the Buongiorno model for convective heat transfer in nanofluids with modifications to fully account for the effects of nanoparticles volume fraction distributions on the continuity, momentum and energy equations. Numerical investigations have be...

We introduce a compact submicron structure consisting of multiple optical microcavities at both the entrance and exit sides of a subwavelength plasmonic slit filled with an absorbing material. We show that such microcavity structures at the entrance side of the slit can greatly enhance the coupling of the incident light into the slit, by improving the impedance matching between the incident pla...

Michael angelasTro, p.e., pToe inTroducTion The objective of this paper is to establish that vehicle speeds and crash rates at modern roundabouts in the United States are related to driver sight distance. This paper investigated the relationship between driver sight distance and passenger vehicle speeds and vehicle crash rates at roundabouts in the United States based on data collected at 26 si...

Heat transfer in the thermal entrance region of trapezoidal microchannels is investigated for hydrodynamically fully developed, single-phase, laminar flow with no-slip conditions. Three-dimensional numerical simulations were performed using a finite-volume approach for trapezoidal channels with a wide range of aspect ratios. The sidewall angles of 54.7 and 45 are chosen to correspond to etch-re...

According to school entry regulations in most countries, the composition of school entrance cohorts is determined by a fixed cutoff date. This procedure creates inter-cohort differences in age and development which can severely influence educational trajectories. Developmental examinations at school entry might be an instrument to mitigate these differences by delaying school entry for children...
