‎in this paper‎, ‎we formulate the sixth-order boundary value problem as fredholm integral equation by finding green's function and obtain the sufficient conditions for existence and multiplicity of positive solution for this problem‎. ‎also nonexistence results are obtained‎. ‎an example is given to illustrate the results of paper‎.

in this paper, we prove the existence of the solution for boundary value prob-lem(bvp) of fractional dierential equations of order q 2 (2; 3]. the kras-noselskii's xed point theorem is applied to establish the results. in addition,we give an detailed example to demonstrate the main result.

Introduction: North Khorasan province has experienced fertility decline and negative population growth during the last decade. Attitude towards value of children is one of the main determining drivers of fertility. Method: The research method was cross-sectional survey. The sample size was 166 married women aged 15-49 that were selected by multistage sampling method. Data collection instrument...

Abstract The main objective of this study was to examine the relationship between Value at Risk (VaR) and expected returns from 2002 to 2013 in Tehran’s Stock Exchange. In this study parametric value at risk, which considers the distribution of returns as normal and the historical value at risk as abnormal, was used to test the presence of the volatility anomaly in the companies listed i...

Values are motivational constructs that determine what is important to us and which goals we choose to pursue. Cross-cultural research suggests that the structure of the human value system is universal, but people and cultures differ in terms of relative value priorities. Differences in psychological value hierarchies can be parsimoniously described using the orthogonal dimensions self-interest...

BACKGROUND Previous studies have revealed significant differences between populations for genotypic frequencies of glutathione S-transferase T1 (GSTT1) and M1 (GSTM1) polymorphisms. In order to find the frequency of the null genotypes of GSTM1 and GSTT1 in Iranian populations, the present study was carried out. METHODS The total study subjects consisted of 1340 unrelated healthy Muslims/Irani...
