Background and Aim: Preparation of tooth structure by laser systems produces a surface with different characteristics. Therefore, selecting an appropriate bonding system is necessary to achieve the maximum bond strength. The aim of this study was to compare the bond strength of Adper Single Bond 2 adhesive and Single Bond Univer-sal to dentin prepared by bur or laser. Materials and Methods: ...

the propagation of utilization of arbitration as a method of dispute resolution depends on the public confidence in the method. in this regard, the independence of arbitrators and their impartiality are necessary conditions for the realization of such confidence. independence and impartiality of arbitrators ensure a fair trial in arbitration and the lack of aforementioned features makes it impo...

Common-mode failures have thus far been considerably overlooked in reliability studies. By their definition, common-mode failures correlate heavily, breaking the assumption of probabilistic independence. This article describes how monitoring a live, largescale network infrastructure provides a realistic environment for analyzing common-mode failures, while also introducing new problems not imme...

background: this study aimed to identify factors contributing to the creation of intellectual capital in the organization of education. the research method is a descriptive and exploratory factor analysis method. a sample: directors and deputies of the second period secondary education department of tehran province. based on stratified random sampling method and based on a sample of 500 was cal...

Abstract Background Last-mile delivery (LMD) is becoming more and demanding due to an increasing number of users traffic problems in cities. Besides, medical crises (like the COVID-19 outbreak) air pollution represent additional motives for transition from traditional socially environmentally sustainable LMD mode. An emerging problem companies postal logistics industry how determine best mode a...

background and objectives: essential oils are complex mixtures containing compounds of several different functional- group classes. depending on the structure, we can distinguish monoterpenes, phenylpropanes, and other components. here in this study two monoterpene compounds of essential oils, i.e. β-pinene and limonene were examined for their antiviral activity against herpes simplex virus typ...

In this thesis we address the problem of leaning Markov network structure from data by presenting the Dynamic GSIMN or DGSIMN algorithm. DGSIMN is an extension of GSIMN algorithm, and works by conducting a series of statistical conditional independence tests on the data, and uses the axioms that govern the independence relation to avoid unnecessary tests i.e., tests that can be inferred from th...

This paper examines the biases and performance of several uncertain inference systems: Mycin, a variant of Mycin. and a simplified version of probability using conditional independence assumptions. We present axiomatic arguments for using Minimum Cross Entropy inference as the best way to do uncertain inference. For Mycin and its variant we found special situations where its performance was ver...
