Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher co...

water is one of the most important restrictive factors in crop production. therefore, optimum use of water resources in line with sustainable agriculture is mandatory. in this research the effects of different amounts of allowed soil water depletion at various growth stages of root sugar beet and its effect on qualitative and quantitative characters of the crop were studied. the experimental de...

Given the critical role played by natural gas in providing electricity, heat, and other essential services, better models are needed to understand dynamics of networks during extreme events. This paper aims at establishing appropriate fast simulation capture slow linepack depletion for ideal isothermal pipeline networks. Instead solving partial differential equations (PDE) on a large scale, thr...

We test for long-term damages from precipitation shocks in rural Brazil by observing wages of households that have permanently migrated from rural to urban areas. We find that large short-term precipitation shocks damage migrants’ long-term wages. We offer an analytical explanation for this outcome: credit-constrained households may be willing to accept lower wages in urban areas following the ...
