Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...

extended abstract 1. introduction in recent years, so many countries have paid many attention to tourism as a strategy to make money and benefit for the local communities. many researchers consider tourism an appropriate strategy for economic and social development of developing countries know. despite all the benefits of community-based tourism, in most developing countries, little authority i...

forest management as one of the important source of production is crucial and critical. in taking over the forest resources as one of the most important of natural resources in the world, it is essential to consider local stakeholders to implement forest action plan for forest co-management. therefore, this study aims at achieving to proper management of forests based on evaluating the stakehol...

This paper develops Order Acceptance for an Integrated Production-Distribution Problem in which Batch Delivery is implemented. The aim of this problem is to coordinate: (1) rejecting some of the orders (2) production scheduling of the accepted orders and (3) batch delivery to maximize Total Net Profit. A Mixed Integer Programming is proposed for the problem. In addition, a hybrid meta-heuristic...

In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows modeling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship, similar to...

In our implementation of geometric resolution, the most costly operation is subsumption testing (or matching): One has to decide for a three-valued, geometric formula, if this formula is false in a given interpretation. The formula contains only atoms with variables, equality, and existential quantifiers. The interpretation contains only atoms with constants. Because the atoms have no term stru...

Iran is a developing country in Middle East which has experienced some political and economical turbulence during the past decades. Government of Iran, after the 1979 Islamic revolution, has devoted considerable resources on national health, including the pharmaceutical sector. As a result, health indicators have improved substantially over the past two decadesnd the availability and affordabil...
