Production Costs and Profitability for Selected Greenhouse-Grown Perennial Plants: Partial Enterprise Budgeting and Sensitivity Analysis

energy sensitivity analysis and greenhouse gas emissions for tea production in guilan province

sustainable development of the production in every region requires consideration of energy flow in the production system, moreover, investigating the production system inputs from environmental management point of view is of high importance. in this study energy use and greenhouse gas emissions is investigated. data were collected through interviews with 75 tea farmers and comparing the results...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

intercultural sensitivity instruction and interfaces among iranian efl learners intercultural sensitivity,language proficiency,ehnic and demograhic backgrounds:an ethnocentrism vs.ethnorelativism perspective

monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...

A Sensitivity Analysis of Timing and Costs of Greenhouse Gas Emission Reductions

This paper analyses the optimal timing and macro-economic costs of carbon emission reductions that mitigate the global average atmospheric temperature increase. We use a macro-economic model in which there are two competing energy sources, fossil-fuelled and nonfossil-fuelled. Technological change is represented endogenously through learning curves, and niche markets exist implying positive dem...
