in this study greenhouse tomato production was investigated from energy consumption and greenhouse gas (ghg) emission point of views. moreover, artificial neural networks (anns) and adaptive neuro-fuzzy inference systems (anfis) were employed to model energy consumption for greenhouse tomato production. total energy input and output were calculated as 1316.14 and 281.1 gj/ha. among the all ener...

T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy inform...

The objectives of this study were, first, to determine the relationship between hepatic glucose release and milk production and, second, to determine the relationship between net hepatic uptake of gluconeogenic precursors and milk production. Nine multiparous ewes were individually penned and fed an alfalfa hay-based diet for ad libitum intake. Catheters were surgically placed in the portal vei...

We examined the role of metabolic CO2 production in the hyperpnea of muscular exercise by comparing the response of alveolar ventilation to moderate levels of exercise with the response to venous infusion of CO2 at rest. Studies were performed in four awake sheep that were trained to run on a treadmill. The sheep had been cannulated for veno-venous extracorporeal perfusion so that CO2 could be ...

There is little evidence for a relationship between probiotic metabolites and host cytokine production. We investigated in the present study the possibility that anti-inflammatory metabolites can be produced in the gut by LKM512 yogurt consumption by using murine macrophage-like J774.1 cells and extracts prepared from the feces of elderly volunteers. These volunteers' acute inflammation had bee...

There are five key interrelated dimensions of the agricultural water/poverty reduction relationship: production, income/consumption, employment, vulnerability/food security, and overall welfare. In general, irrigation access allows poor people to increase their production and incomes and enhances income diversification opportunities, reducing vulnerability caused by seasonality and other factor...
