This meta-analysis summarizes teaching effectiveness studies of the past decade and investigates the role of theory and research design in disentangling results. Compared to past analyses based on the process–product model, a framework based on cognitive models of teaching and learning proved useful in analyzing studies and accounting for variations in effect sizes. Although the effects of teac...

Animal studies are a foundation for defining mechanisms of atherosclerosis and potential targets of drugs to prevent lesion development or reverse the disease. In the current literature, it is common to see contradictions of outcomes in animal studies from different research groups, leading to the paucity of extrapolations of experimental findings into understanding the human disease. The purpo...

in this study, the time-average velocity in the near wake of a two-dimensional notch-back car model that located in the wake of a trailer has been investigated. the present experiments were carried out in an open circuit low-speed wind tunnel made by fara sanjesh saba ltd, in iran and was used to simulate uniform air flow. results show: at the close spacing, time- average velocity profile at th...

background: the present study was designed to evaluate the secondary microglial activation processes after spinal cord injury (sci). methods: a quantitative histological study was performed to determine ed-1 positive cells, glial cell density, and cavitation size in untreated sci rats at days 1, 2, and 4, and weeks 1, 2, 3, and 4. results: the results of glial cell quantification along the 4900...

This editorial discusses some statistical principles that may be useful in guiding authors of manuscripts submitted to Animal Feed Science and Technology (AFST) for consideration for publication. The editorial also discusses some common experimental designs and statistical models used by AFST authors, including some of the most frequent problems that cause misunderstandings and disputes among a...

in this work, experimental kinetics data of methane hydrate decomposition at temperatures ranging from 272.15 to 276.15 k and at pressures ranging from 10 to 30 bars were modeled by using chemical affinity. this model proposed a macroscopic model which is independent of any intermediate mechanism like heat or mass transfer. the results show there is good agreement with experimental data. also t...

The R package vdg provides a flexible interface for producing various graphical summaries of the prediction variance associated with specific linear model specifications and experimental designs. These methods include variance dispersion graphs, fraction of design space plots and quantile plots which can assist in choosing between a catalogue of candidate experimental designs. Instead of restri...
