BACKGROUND Despite increasing evidence that human parturition is associated with alteration in gene expression in the uteroplacental unit, the precise mechanisms that elicit spontaneous term labor in humans remain unknown. Our goal in this study was to compare the mRNA expression pattern of the trophoblast layer of normal term placenta between women who had given natural birth (labor group) and...

In this study, by using manufacturing firms' cost functions and their demand for inputs, we attempt to find the relationship between production inputs and energy carriers during (2005-ا2013). A dynamic model is implemented to derive the short and long-run elasticities of demand and substitution. The results show that during the period 2005-ا2013, energy and capital were complement for labor, a...

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...

This paper proposes a dynamic economic model with wealth accumulation and human capital accumulation. The economic system consists of one production sector and one education sector. We take account of three ways of improving human capital: learning by producing, learning by education, and learning by consuming. The model describes a dynamic interdependence between wealth accumulation, human cap...
