Student-based teaching evaluations are one critical component of instructor and course evaluation in most universities. The purpose of this study is to critically examine several factors that drive student-based ratings of instructors and courses in an undergraduate mechanical engineering program. The findings are based on a statistical study of student ratings in 181 mechanical engineering cou...

In this paper the designing products of B.A. Sophomore students of architecture in TehranUniversity who were divided into two kinds of learning namely technical and skill-based learning. In technical learningthe subjective steps of creativity process i.e. "insight", "preparation", "incubation", "intuition", and "verification"were discussed and it was suggested that these steps cannot be taught ...

Abstract Single-carrier (SC) transmission is a transmission equipped with frequency-domain equalization (FDE) is suitable for uplink transmission because of its low peak-to-average power ratio (PAPR) property. Square-root Nyquist filtering is widely used, where the filter shape is controlled by the roll-off factor  from 0 to 1. Nyquist filtering with =1 occupies twice bandwidth of the origina...

Past research indicates several factors influencing teaching evaluation ratings instructors receive. We analyzed teaching evaluations from psychology courses during fall and spring semesters of 2003– 2004 to determine if class size, class level, instructor gender, number of publications (faculty instructors), average grade given by the instructor, and instructor rank predicted teaching evaluati...

Although sildenafil citrate (SC) is used extensively for erectile dysfunction, oral delivery of SC encounters many obstacles. Furthermore, the physicochemical characteristics of this amphoteric drug are challenging for delivery system formulation and transdermal permeation. This article concerns the assessment of the potential of nanomedicine for improving SC delivery and transdermal permeation...

Transcriptomic data have become a fundamental resource for stem cell (SC) biologists as well as for a wider research audience studying SC-related processes such as aging, embryonic development and prevalent diseases including cancer, diabetes and neurodegenerative diseases. Access and analysis of the growing amount of freely available transcriptomics datasets for SCs, however, are not trivial t...

BACKGROUND This randomized, single-blinded, controlled study compares the effectiveness of two modes of delivering the same set of oral hygiene instructions: those loaded on a computer-assisted teaching format versus those given personally by a self-care instructor. METHODS 60 participants with mild to moderate periodontitis were randomized to either the computer-teaching format or the self-c...
