introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
In this paper, we present results of simulation experiments with the TIME-model on the issue of mitigation strategies with regard to greenhouse gases. The TIME-model is an integrated system dynamics world energy model that takes into account the fact that the system has an inbuilt inertia and endogenous learning-by-doing dynamics, besides the more common elements of priceinduced demand response...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
Suggestions on international cooperation in climate policy beyond 2012 include substi-tuting or complementing international environmental agreements (IEA) with technologyoriented agreements (TOA). We look at the impact of TOA on environmental cooperationin the framework of coalition stability. Using a numerical model, we analyze the differ-ences of several TOA and how they inter...

In this study, solutions for machinery layout with the aim of reducing transportation costs will be discussed. To do this, imperialist competitive algorithm (ICA), which is a very complicated and effective meta-heuristic algorithm is introduced. In the offered algorithm, different kinds of machinery layout are considered in single-row as country and then the best possible layout is developed ba...
Providing clean and affordable water to meet human needs is a grand challenge of the 21st century. Worldwide, water supply struggles to keep up with the fast growing demand, which is exacerbated by population growth, global climate change, and water quality deterioration. The need for technological innovation to enable integrated water management cannot be overstated. Nanotechnology holds great...
Economic growth in Sub-Saharan Africa has been characterized by deindustrialization. Conventional economists argue that this is due to a bad environment for business decision making. This paper provides a classical explanation for deindustrialization, the failure to solve the food problem. That is, food staple prices have risen rapidly resulting in labor becoming costly, although physically abu...
The detection and governmental punitive agency is responsible for supervision on correct implementation of the business laws in Iran. Several criteria are involved in performance assessment of detection and governmental punitive agency. The interaction between criteria and sub-criteria may occur in real situations. Moreover, the performance measurement should be accomplished in a multi-period h...
