Background: Determining the gap in the quality of educational services, followed by the adoption of appropriate strategies for eliminating or reducing the existing obstacles, is considered the first basic step in developing quality improvement programs for universities. Therefore, this study was conducted to evaluate the quality of educational services of Iranian medical universities.Methods: T...

The effect of the adsorption Ba atoms with a thickness theta≤3-4 monolayers and implantation + ions an energy E 0 =0.5-2 keV on density states electrons in valence band, parameters bands, emission optical properties Ge(111) has been studied for first time. It is shown that during theta=1 monolayer, value thermoelectric work function φ decreases by ~ 1.9 eV, secondary electron coefficient quantu...

A field experiment was conducted under a wheat-maize rotation system from 1990 to 2006 in North China Plain (NCP) to determine the effects of N, P and K on yield and yield gap. There were five treatments: NPK, PK, NK, NP and a control. Average wheat and maize yields were the highest in the NPK treatment, followed by those in the NP plots among all treatments. For wheat and maize yield, a signif...

Using magnetocapacitance data, we directly determine the chemical potential jump at low temperatures of about 25 mK when the filling factor traverses the spin gap at n ­ 1 and the cyclotron gap at n ­ 2. The chemical potential jump for the cyclotron gap is found to increase proportionally to the magnetic field with a slope that is determined by an effective mass 0.071m0. The data yield a spin g...

The paper provides a discussion of the most relevant aspects of yield curve modeling. Two classes of models are considered: stochastic and parsimonious function based, through the approaches developed by Vasicek (1977) and Nelson and Siegel (1987). Yield curve estimates for Croatia are presented and their dynamics analyzed and finally, a comparative analysis of models is conducted. Keywords—the...

Currently a new version of the distance education platform WeLearn [3] to be combined with an agent system ([1], also developed locally) for providing advanced services [2] is under development. In a previous stage of the project software was created to automatically derive keywords from documents, either from the different versions of metadata already contained (various Microsoft file formats,...

As our ability to store information increases, the mechanisms we employ to access that information become ever more important. In this paper, we present Archosum, a prototype of an organizational system that attempts to encapsulate the benefits of both hierarchical and keyword systems. By introducing abstract entities, Archosum provides a simple interface with which users can build and maintain...

ODUCTION ar sensors with dual-polarization capability etter understanding and characterization of hazards. Advanced knowledge-based hazard algorithms would require better knowledge of ttering characteristics of hydrometeors such as , hailstones, and snowflakes. Especially, characteristics becomes important for utilize phase-array dual-polarization radar Traditionally, theoretical approaches [1]...
