a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولLIFTING MODULES WITH RESPECT TO A PRERADICAL
Let $M$ be a right module over a ring $R$, $tau_M$ a preradical on $sigma[M]$, and$Ninsigma[M]$. In this note we show that if $N_1, N_2in sigma[M]$ are two$tau_M$-lifting modules such that $N_i$ is $N_j$-projective ($i,j=1,2$), then $N=N_1oplusN_2$ is $tau_M$-lifting. We investigate when homomorphic image of a $tau_M$-lifting moduleis $tau_M$-lifting.
متن کاملCapacitor Placement in Distorted Distribution Network Subject to Wind and Load Uncertainty
Utilizing capacitor banks is very conventional in distribution network in order for local compensation of reactive power. This will be more important considering uncertainties including wind generation and loads uncertainty. Harmonics and non-linear loads are other challenges in power system which complicates the capacitor placement problem. Thus, uncertainty and network harmonics have been con...
متن کاملA comparison of two electric toothbrushes with respect to plaque removal and subject preference.
PURPOSE To compare the safety and plaque removal efficacy, and subject preference of two electric toothbrushes in a single-blind, randomized, split-mouth study. MATERIALS AND METHODS The devices studied were the Braun Oral-B 3D Plaque Remover and the sonicare electric toothbrush. The 3D toothbrush combines the clinically proven oscillating/rotating action of the D9 with a sonic frequency puls...
متن کاملDistributed Generations Optimal Placement and Sizing in Unbalanced Distribution Systems with Respect to Uncertainties
Distributed generations are renewable sources that do not create environmental pollution and install near the site of consumption. Also, the generated power of wind and solar sources are faced with uncertainty due to the dependence on external factors. With determination of the appropriate location and size of these sources in distribution networks their positive effects can be realized. But it...
