The aim of this study is investigation of the swelling potential of the Bonab city’s soils and created the empirical relations between physicochemical properties of the clayey soils of Bonab with the swelling potential. The studied area is located about 130 km southwest of Tabriz in northwest of Iran. Geologically Bonab is covered by the Quaternary alluvials and recent soils which mostly is fine-grained contains different amounts of clay minerals where causes several events like swelling. In order to assessment of the swelling potential and characteristics of Bonab soils and establish relationships between these properties, the extensive field study especially on the agricultural fields (Bonab is the agricultural-based city), sampling and laboratory tests (classified in physical, chemical and mechanical) are conducted. For the reducing the investigation’s errors, the 20 different location is selected and sampling is taken as representative. The results of laboratory tests are classified based on United States Department of Agriculture (USDA) classification which indicated the most of Bonab soils are clay, clay loam and silty clay with the sandy clay and salt. Also, according to the swelling potential indirect assessment, these soils are located in medium to high swellability. تفاصيل المقالة

In a situation where manufacturing companies are under intense competition, they are producing a variety of products, and sometimes they do not pay attention to the environmental costs of using different materials. However, the implementation of environmental management practices such as green supply chain management can help to prevent environmental pollution, in addition to maintaining the competitive advantage of companies. This research investigates the role of green human resources management in promoting greenhouse gas supply goals at the compost recycling plant in Isfahan industrial city. In this study, a conceptual model related to green supply chain management and factory business performance was used through three organizational variables: job satisfaction, operational efficiency, and inter professional productivity as intermediaries. Statistical analyzes based on data collected through A total of 92 questionnaires were conducted in the disposable utensil industry. Reliability and validity of the research model and questionnaire were tested and confirmed. In order to test the hypotheses, partial least squares technique has been used in the structural equation model. Some of the previous findings of this study suggest a direct relationship between the implementation of green human resource Management and the business performance of a factory. All research hypotheses were approved in the form of green human resources management and related factors. In general, the findings of this study are consistent with previous studies in other parts of the world. Also, few studies in this area were conducted based on the theory of resource dependency. تفاصيل المقالة

The presented study is attempted to investigate the landslide susceptibility of the Bonab city located in Urmia lake basin in East-Azerbaijan, NW of Iran. As methodology the coupled method contain analytical hierarchy process and fuzzy logic, named FAHP was applied to risk-ability evaluation and prepares sliding potential maps. For this purpose, three main triggering factors identified for the susceptibility assessment which is classified as geomorphology, geology and human activities where each class has several sub-classes. According to the landslide susceptibility assessment and zonation map, the main risk zone is located in east to southeast part on the Bonab city in Malekan-Bonab highway route. تفاصيل المقالة
