This research was conducted to evaluate the sustainability of rice production using fuzzy logic in Mazandaran province,*** untapped use of modern agricultural technology,such as agricultural machinery,has become a global dilemma,which has forced governments and environmentalists to take a serious stand against the dangers of massive non-standard agricultural practices in the *** types of mechanization,socioeconomic,and economic modeling were used to determine the sustainability and their values were collected through interview method using a 320-item questionnaire from 2016 to *** evaluation was carried out using soil and climate characteristics,so that about 27.4%of the area was in the perfectly suitable range(S1),35.2%in the appropriate range(S2),19.5%in the critical range(S3),and 17.9%in the inappropriate range(N)for rice *** were selected from two regions(R1 and R2)by the GIS on two lower levels and more than one hectare(A1,A2)according to agricultural methods(mechanical and traditional).The results showed that the highest and lowest means of the product were 4314.44 and 3501.95 kg ha1,*** sustainability of production was within the range of“sustainability”and“almost sustainable”in terms of mechanistic and economic factors in the fuzzy range of“moderate sustainability”and also with respect to social factors that are in a better position than mechanistic and economic *** of final sustainability model showed that the average of the lasting sustainability index was in the range of“almost unsustainable”and“moderate sustainability”.

Rice science 2014年第2期21卷 116-122页

作者： Abozar NASIRAHMADI Bagher EMADI mohammad hossein abbaspour-fard Hamid AGHAGOLZADE Department of Agricultural Machinery Ferdowsi University of Mashhad Haraz Extention and Technology Developement Centre

The effects of moisture content （8%, 10%and 12%）, variety （Tarom and Fajr） and parboiling on milling quality of rice as a function of milling recovery （MR）, head rice yield （HRY）, degree of milling （DOM） and whiteness were investigated. The parboiled grains was prepared with three soaking temperatures of 25 oC, 50 oC and 75 oC and three steaming times of 10, 15 and 20 min. As a result of parboiling, the increasing rates of MR and HRY values were 7.8%and 14.3%for Tarom and 9.8%and 10.0%for Fajr, respectively, and the decreasing rates for DOM and whiteness were 6.6%and 10.8%for Tarom and 6.8% and 10.5% for Fajr, respectively. Moreover, decreasing moisture content to 8%maximized MR （75.8% for Tarom and 74.3% for Fajr） and HRY （65.8% for Tarom and 57.0% for Fajr） while increasing that to 12%revealed maximum values of DOM （6.1%for Tarom and 6.2%for Fajr） and whiteness （24.8%for Tarom and 28.2%for Fajr）.

研究由开孔聚合物和金属/聚合物泡沫芯制成的轻质夹层板的力学性能和能量吸收性能。通过结合聚合物树脂的增材制造和三层金属(Ni/Ni-Cu/Ni)的电沉积制备多层夹层板,每英寸孔数(PPI)为4、5和6。测试样品在单轴压缩变形过程中的屈服强度,计算其能量吸收密度、互补能和比吸收能(SEA)。结果表明,与相同厚度的纯Ni和Cu夹层板相比,复合夹层板的性能有明显改善。增加PPI和金属层可提高力学性能和能量吸收性能,当PPI为6时,屈服强度(能量吸收密度)由聚合物夹层板的0.12 MPa(0.12MJ/m^(3))提高到三层金属夹层板的1.83MPa(0.67 MJ/m^(3))。对夹层板结构归一化能量的研究表明,夹层板具有可预测的塑性变形行为,多金属层改善了新型夹层板的力学性能。其能量吸收性能的显著增强可保证材料在不同行业的独特应用。
