The deep submicron semiconductor technologies will make the worst-case design impossible, since they can not provide design margins that it requires. Research directions should go to typical-case design methodologies, where designers are focusing on typical cases rather than worrying about very rare worst cases. They enable to eliminate design margins as well as to tolerate parameter variations...
cotton (gossypium hirsutum l.) as a unique crop in natural fiber production has an important role in texture industry. it has also a large share in oil production for human nutrition and as a protein concentrate for animal feeding. therefore, cotton role in job opportunities in agriculture, industry and business divisions are undeniable. in order to determine the share of each direct and indire...
In this investigation, the effect of heat input of SMAW process on the microstructure and mechanical properties of Hadfield steel weld joints was investigated. For this purpose, 4 annealed sheets with thickness 2 mm prepared from Hadfield steel and then welding applied by SMAW process with 6.75 and 11.25 kJ/mm heat input values. The evaluation of the microstructures of welding joints was condu...

The present study attempts to investigate the potential relationship between input energies, performance production of greenhouse basil, and greenhouse gases emitted from this product. The data were collected from 24 greenhouses using a questionnaire and verbal interaction with farmers. Results of the study showed that the total input energy and total output energy for basil production were 119...
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
