The purpose of this study is to evaluate the efficiency of date growers in Saravan County using non-parametric methods. The measurement of date farmers’ efficiency and the comparison of their performance to with one another can play an important role in improving their efficiency and productivity. One of the common methods to measure efficiency is data envelopment analysis (DEA). Despite its ad...

The stability analysis of rock slopes is a complex task for the geotechnical engineers due to the complex nature of the rock mass in a tropical climate that often has discontinuities in several forms, and consequently, in several types of slope failures. In this work, a rock mass classification scheme is followed in a tropical environment using the Rock Mass Rating (RMR) and Geological St...

background: the opening and closing of the implantation window is important for successful pregnancy in eutherians. the recent study demonstrated that the window of uterine receptivity was prepared by the sole action of progesterone in mice, but the mechanism to close the window remained to be elucidated. methods: the pregnant mice were ovariectomized on the evening on the third day of pregnanc...
