although, coumarins are a group of compounds which are naturally found in some plants, they can be synthetically produced as well. because of their diverse derivatives, origin and properties most of them can be used for medicinal purposes. for example, they can be used against fungal diseases or in studying structure and biological properties of antifungal agents to discover new compounds with ...

the environmental rules of reverse logistic networks have caused important economic growth in the past decades. to integrate forward logistic networks with reverse logistics networks a helpful method is to design both networks simultaneously. considering more retrieval choices in modeling reverse logistic systems can be very critical. this article contains a mixed integer linear programming mod...

This paper is an attempt to assess the potential and usefulness of ANN based modeling for evaporation prediction from a reservoir, where in classical and empirical equations failed to predict the evaporation accurately. The meteorological data set of daily pan evaporation, temperature, solar radiation, relative humidity, wind speed is used in this study. The performance of feed forward back pro...
