BACKGROUND Clinical reasoning ability is an important factor in a physician's competence and thus should be taught and tested in medical schools. Medical schools generally use objective structured clinical examinations (OSCE) to measure the clinical competency of medical students. However, it is unknown whether OSCE can also evaluate clinical reasoning ability. In this study, the authors invest...

The paper presents an analytical solution for dispersion of a solute in the peristaltic motion of a micropolar fluid in the presence of both homogeneous and heterogeneous chemical reactions. The average effective dispersion coefficient has been found using Taylor’s limiting condition under long wavelength approximation. The effects of various relevant parameters on the average coefficient of di...

A new spray technique coupled with atomic force microscopy is developed to obtain the absolute number of carbon nanotubes in a unit volume. By using the present technique, the absolute molar absorbance coefficient of single-wall carbon nanotubes (SWNTs) has been determined and found to be ca. 2-5 x 10(7) L mol(-1) cm(-1). This molar absorbance coefficient enables us to deal with carbon nanotube...

BACKGROUND Statins are effective for primary prevention of cardiovascular (CV) disease, the leading cause of death in the world. Multinational guidelines emphasize CV risk as an important factor for optimal statin prescribing. However, it's not clear how primary care providers (PCPs) use this information. The objective of this study was to determine how primary care providers use information ab...

Mental health plays an important role in ensuring the dynamism and efficiency of every community. Since human resources have crucial role in the cultural, social and economical developments of communities, students also are the brilliant segments of society and creators of future of each country therefore, assessing of their mental health is of utmost importance. The aim of the present study is...

An analytical study is presented of dispersion in steady and oscillatory open-channel flows under the combined effects due to reversible sorptive phase exchange with the bed and irreversible air–water reaction on the free surface. The free-surface reaction is assumed to be so weak that the asymptotic mean concentration can be developed well before undue substantial loss to the air occurs. The e...

performance of the fiber optic networks with different physical topologies such as point-to-point, bus, ring and star, with respect to requirements as bit rates, topology structure, bit. error rate (ber) and optical component characteristics including optical amplifiers, filters, sources and detectors, are analyzed and simulated. for this purpose, maximum number of supportable nodes and throug...

The success of every educational activity hinges on the quality students’ learning experiences. This survey-based study analysed engineering perceptions their experiences in a future-fit classroom (FFC) compared with conventional classrooms. In this study, structured interviews using online questionnaire, that were filled out by students, was employed as tool. Descriptive statistics for mean, c...

BACKGROUND Diarrhea is a leading cause of morbidity among children under 5 years of age in low- and middle-income countries yet the additional effects and sequelae, such as cognitive impairment associated with diarrhea, have not been quantified. METHODS We quantified the association between diarrhea prevalence and cognitive outcomes while controlling for linear growth in 4 study populations. ...
