in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...

Several compelling factors drive spread of green buildings. Growing tenant demand due to lower operating costs, higher worker productivity and reputational issues forces the real estate sector to adopt efficient building techniques. Overall, operating costs for leadership in Energy and Environmental Design (LEED) certified buildings are 8-9% lower than for regular buildings. Over the life cycle...

What Is Productivity? In primary productivity of plants, solar energy is transformed to biomass. Using photosynthesis, green plants convert solar energy, carbon dioxide, and water to glucose and other carbon-based compounds and eventually to plant tissue. Gross primary productivity is the product of that photosynthetic fixation of carbon, whereas net primary productivity is the carbon that is a...

The impact of carbon emission trading (ETS) has been widely investigated. In contrast to the existing studies, this article explores for first time theoretical relationship between ETS and industrial green total factor productivity (IGTFP) tests it empirically. Furthermore, investigates mediating mechanisms possible regional heterogeneity influence on IGTFP. To end, a time-varying difference-in...
