Water is a basic demand of sustainable development in most regions of the world. The non-uniform temporal and spatial distribution of water resources will lead to water shortage in arid and semi-arid areas. Pishin catchment is one of the most important catchments in South-East Iran. The basin had been faced with consecutive droughts in recent years. On the other hand, water resources developmen...

ziziphora tenuior, named kakooti in farsi, is one of the aromatic and medicinal plants of a wide distribution in iran. in this study, rapd molecular markers, (by utilization of 16 primers) was applied to determine the genetic diversity of 39 samples of ziziphora tenuior from 21 geographical regions in iran. a number of 100 polymorphic bands out of 110 amplified ones was produced and analyzed th...

This study uses a sample of young Australian twins to examine whether the findings reported in [Ashenfelter, Orley and Krueger, Alan, (1994). dEstimates of the Economic Return to Schooling from a New Sample of TwinsT, American Economic Review, Vol. 84, No. 5, pp.1157–73] and [Miller, P.W., Mulvey, C and Martin, N., (1994). dWhat Do Twins Studies Tell Us About the Economic Returns to Education?:...

Agricultural beneficial management practices (BMPs) are popular strategies for mitigating non-point sources of pollution. There are economic costs for BMP placement on agricultural lands mainly because it affects profit margins of farm operations. Given the cost implication and biophysical heterogeneity of farm lands, 8 the spatial targeting of BMP placement is consequential to their cost-effec...

The contribution of the ‘new economy’ to economic growth in developing countries has so far been minimal. Despite the recent hype, the ‘old economy’ will for long be the fundamental force behind economic growth in transition economies. Nonetheless, in the longer run the ‘new economy’ offers great potential for faster economic growth in postsocialist economies. Realizing this potential is howeve...

The contribution of the ‘new economy’ (NE) to economic growth in developing countries has so far been minimal. Despite the recent hype, the ‘old economy’ will for long be the fundamental force behind economic growth in transition economies. Nonetheless, in the longer run the NE offers great potential for faster economic growth in postsocialist economies. Realizing this potential is however not ...

A simplest multi-sector dynamic model for regional economy is a normative balance mathematical model, but it contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. Only confidence intervals for the unknown parameters can be computed from the statistical data. This work presents a method for estimation of the model parameters by application of...

The hesitant fuzzy soft set (HFSS), as a combination of hesitant fuzzy and soft sets, is regarded as a useful tool for dealing with the uncertainty and ambiguity of real-world problems. In HFSSs, each element is defined in terms of several parameters with arbitrary membership degrees. In addition, distance and similarity measures are considered as the important tools in different areas such as ...

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...
