Abstract
Today, due to the ever-increasing competition between organizations and uncertain environments that have been created by many changes in customer needs, using an efficient supply chain can be considered as a competitive advantage for any organization. In this regard, one solution is lean approach. Lean approach helps to eliminate waste in the supply chain. On the other hand, based on the state of Iran and the abundance of oil and gas resources, the implementation of lean approach in the supply chain of the organizations operating in this field is very important.
In order to conduct this study that has been carried out in one of the largest companies operating in the offshore sector and the aim of this research is to provide a lean supply chain model in offshore oil and gas industry and accordingly, executive solutions can be presented. First, by reviewing the literature and opinion poll at the experts, the 11 factors that lead to lean supply chain were identified. Then, using fuzzy analytical heararchy process and interpretive structural modeling approach, the research model was developed and based on it, the factor: “leadership and management”, “information sharing”, ‘financing” and “supplier contact” identified as the most influential and “minimizing the delivery time” was identified as the most influential factor. In the next step, the model was validated in quantitative and statistical analyzes as well as qualitative. Finally, some suggestions were made to achieve lean procurement process in the offshore sector of the oil and gas industry.

Abstract
Totalitarian regimes have their own characteristics that reproduce them as much as possible in other fields, especially science and academia. Studying the challenge between the social sciences and totalitarian rule can be instrumental in the development of social science. The purpose of this study is to make a comparative-historical comparison of this relationship at a time of totalitarian rule in Germany, the Soviet Union and China. The study method is comparative-historical and the reported experiences in three cases of Nazi Germany, Soviet Union and Communist China have been compared historically. Data were collected from second-hand sources and analyzes were presented in a comparative-historical manner. The findings show some similarities and differences between Nazi and communist totalitarianism. Nazi totalitarianism had an a-priori negative mentality towards social science and avoided any institutionalization and by creating an obstruction against the activities of scientists, provided the ground for the migration of social thought, while communist totalitarianism had an a-priori positive mentality towards social science and tried to institutionalize and attract scientists in this field to produce favorable social science. Both forms of totalitarianism, at the height of their tyranny, sought a government-dependent, non-critical, quantitative, practical, and useful social science to perpetuate power.

Abstract
Physicochemical and mechanical properties of wheat grains can have a great impact on the quality of the final products (bread). Therefore, correct selection of wheat cultivar for specific applications seems to be crucial. In this study, the differences in the physicochemical and mechanical properties (under compression and impact loadings) of ten Iranian wheat cultivars (Azar2, Alamut, Bam, Bahar, Chamran, Shiraz, Falat, Keras Adl, Marvdasht, and Nicknejad) were studied. Moreover, the relationship between these properties was investigated. The results indicated that the type of cultivar had significant influences on physicochemical and mechanical properties. The results of regression analysis between physicochemical and mechanical properties showed a significant correlation between protein content and particle size index (r2= 0.6). Moreover, the protein content could be significantly correlated with the parameters obtained from mechanical tests (r2> 0.50). Among the mechanical parameters obtained from compression and impact loading, the apparent elastic modulus and the specific breakage energy established maximum correlation (r2= 0.77 and 0.78, respectively) with the protein content. Similarly, significant correlations were found between particle size index and mechanical parameters (r2>0.60). Hence, the wheat protein content and particle size index, which have great impacts on quality of the final product, can be estimated by a few simple mechanical tests on the wheat kernels.
