introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
Background and purpose: The midwife's self-efficacy in supporting mothers during labor affects the onset of midwifery support in labor and childbirth. To date, there is no appropriate national instrument for measuring midwives self-efficacy of labor support in Iran. The present study aimed to investigate the factorial structure, validity and reliability of the Persian version of the self-effica...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
Background and Aim: Human-information interaction, either in every day life or in research approaches, depends on pre-assumptions about “what information is”. Sometimes this pre-assumptions become axiomtic in a way that we must return to primary concerns about them to explore new social phenomenas. Information as an object is one of pre-assumptions. In this paper, the mentioned pre-assumptions ...
The behavior of correlation functions is studied in a class of matrix models characterized by a measure exp(−S) containing a potential term and an external source term: S = N tr(V (M)− MA). In the large N limit, the short-distance behavior is found to be identical to the one obtained in previously studied matrix models, thus extending the universality of the levelspacing distribution. The calcu...
In multiple indicator models, there are several indicators for one trait–method unit. In the less restrictive model, there is one factor for all indicators belonging to the same trait–method unit. The correlations between these factors constitute a latent MTMM matrix. The correlation coefficients of this latent MTMM matrix are not distorted by measurement error and allow a more appropriate appl...
Background and purpose: World Health Organization (WHO) considers continuing medical education (CME) as an urgent necessity. The purpose of this study was to provide an effective teaching model in CME programs. Materials and methods: In this cross-sectional study, 229 faculty members from medical universities in Iran participated. They had teaching experiences in the CME programs of Mazandaran...
Polyurethane/zeolite 13X nanocomposite films were fabricated using solution casting method. The synthesized nanocomposite films were structurally characterized using SEM, TGA and tensile analysis. SEM images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. Better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
