the goal of this article is mapping urban management science. the main question of the research is “what are the subject areas of urban management science and how is the relation between these subject areas?” the map of urban management science can help to recognize urban management and its subject areas and can help policy makers to get familiar with the priorities in this subject area. for th...

a synoptic method based on stream analysis is applied to understand the governing mechanism of summer rainfall occurrence in the south of iran. based on this, the rainfall data of 152 stations of iran were analyzed for a 33-year period (1970-2002). investigating the spatial and temporal distribution of summer rainfall, a typical rainy region is recognized in the south east of iran. it is found ...

bitter asafetida (ferula asa-fetidae l.) is a wild plant of the family umbelliferae. the present study was carried out to determine the type of dormancy of the plant’s seed, and find out the most suitable treatment needed for quick germination of seeds. twelve treatments including ga3 (500, 1000, 1500 ppm), kno3 (0.1, 0.2 0.3 molar), rinsing (24, 48, 72 hour),elimination of seed coat (one year-...

introduction climate is a system consisting of atmosphere, lithosphere, cryosphere, hydrosphere, and biosphere. this system is involved in the exchange of energy and moisture among these five components. the exchanges link the atmosphere as the central component of the climate to other spheres. changes do not occur separately in this system; rather change in one component contributes to reactio...

in order to investigate the effects of different irrigation regimes and zeolit on the yield, yield componentsand relative leaf water content of sorghum, a field experiment was conducted in split plot in time andspace based on randomized complete block design with three replicates in research station of shahidbahonar university of kerman in 2011. irrigation regimes (100, 80, 60 and 40% of field ...

common bacterial blight (cbb) of bean caused by xanthomonas axonopodis pv. phaseoli is a seriously important disease that adversely affects the quantity and quality of seed. cultivation of resistant cultivars is the most effective method of  the disease control. to identify disease resistant genotypes of selected beans, an experiment was conducted in  agriculture and natural resources research ...

the aim of this study was to investigate the relationships between air, noise, light and landscape pollution on job stress of staff work in high schools of different districts (1, 2, 10 and 11) of tehran. this stress can reduce the efficiency of the personnel. the number of people participated in this research was 250, selected by random from different schools of the districts. the questionnair...

in this study two intelligent systems, based on adaptive neuro-fuzzy inference systems (anfis) and artificial neural networks (anns) of forecasting municipal solid wastes (msw) generation has been proposed. anfis and anns as an intelligent tool compared with together was used to monthly prediction of msw generated in tehran. monthly amount of solid wastes (sw), total monthly precipitation, mont...

this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

gypsum found in the soil beneath the foundation of structures, specially hydraulic structures, can cause serious damage to them. the mechanical behavior of gypsiferous soils has not so far been investigated in detail except for the works of petrukhin (1993). here, it has been tried to investigate the mechanical behavior and the effect of soil being leached on settlement and strength of these ki...
