Introduction For dose measurement in Megavoltage (MV) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. Therefore, the result of measurement should be corrected with a displacement perturbation correction factor (Pdis) or using an effective point of measurement (EPOM). The aim of this study is to calculate the EPOM for cylindrical ion chamber and...

Let $R$ be a unitary ring with an endomorphism $σ$ and $F∪{0}$ be the free monoid generated by $U={u_1,…,u_t}$ with $0$ added, and $M$ be a factor of $F$ setting certain monomial in $U$ to $0$, enough so that, for some natural number $n$, $M^n=0$. In this paper, we give a sufficient condition for a ring $R$ such that the skew monoid ring $R*M$ is quasi-Armendariz (By Hirano a ring $R$ is called...

Objective: The Self-Compassion Scale (SCS) which originally developed by Neff (2003a) is based on the assumption that the self-compassion comprised by self-kindness/self-judgment, common humanity/perceived isolation, and mindfulness/over-identification. This research was aimed to confirm the six-factor structure of SCS. Methods: 265 university students entered the research to assess the psyc...

This study was aimed to evaluate the correlation between in vitro fermentation and in situ degradation parameters and to predict dry matter degradability and energy protein synchronization of roughage based diets. Different inclusion of roughage in diets [roughage 50% diet (R50D), roughage 60% diet (R60D), roughage 65% diet (R65D) and roughage ...
