In this paper we investigate the Green‎ ‎graphs for the regular and inverse semigroups by considering the‎ ‎Green classes of them‎. ‎And by using the properties of these‎ ‎semigroups‎, ‎we prove that all of the five Green graphs for the‎ ‎inverse semigroups are isomorphic complete graphs‎, ‎while this‎ ‎doesn't hold for the regular semigroups‎. ‎In other words‎, ‎we prove‎ ‎that in a regular se...

nowadays programming and designing of green space of urban area, without considering the criteria for 'optimum standards of green areas is impossible, . in this research, it is tried to determine, the per capita standard rate of green space in different regions of gorgan city, . the applied methedology is an integration of several international and local methods, based on the principles of...

Green belt is defined as a narrow green area surrounding an urban area. Shiraz green belt has been developed through 9 projects with a variety of purposes since 2005. The development of green belt is being considered in a number of Iranian cities, and therefore, investigation of Shiraz green belt’s purposes and challenges could contribute to an appropriate planning by decision makers. The main ...

This experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. In this experiment 192 Hy-Line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. The tr...

The green hydroponics walls are among new kinds of building facades, which receive more attention from architects lately. In addition to the positive effect these walls have in maintaining humidity in arid regions, they also have positive thermal performance in both cold and hot weather conditions. Therefore, they are in the center of designers’ focus for public spaces such as schools. In terms...

due to the high value of land, low area of green space and its unsuitable distribution in the regions, the use of green roof technology in iran’s metropolises seems a suitable option in order to improve the quality of urban environment. using hierarchical analysis technique (ahp) and a survey research, this study identifies challenges which prevent the extension of green roofs in iran. so by st...

this experiment was carried out to study the effects of corn and green gram intercropping on yield and some quality characteristics of forage at agricultural research station of gorgan during summer 2006 & 2007. the experimental design was a randomized complete block design (rcbd) with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops used in t...
