This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

Cooperative have always been considered institutions capable of solving major problems in the process of development in different countries. These institutions has evolved along with theories of development from government dependent organization to independent, people centered with the objective of being equal-opportunity systems for all members in order to be responsive to current goals of dev...

To evaluate the effects of tillage and planting systems on soil physical properties, grain yied and its components, and milling recovery of rice (cv. Hashemi), an experiment was conducted at Rice Research Institute of Iran in 2017 and 2018 cropping seasons-using split plot arrangements in randomized complete block design with three replications. The experimental factors were; tillage methods (m...

Population growth and urbanization, increase in number of private vehicles, low-width’s streets and lack of marginal parking spaces, especially in central parts of cities, have brought numerous problems for big and populated cities. Locating mechanized parking lots, which with occupying less area have a high parking capacity, is of the necessities of urban and traffic planning in large cities. ...

In this paper, we have presented a heterojunction gate all around nanowiretunneling field effect transistor (GAA NW TFET) and have explained its characteristicsin details. The proposed device has been structured using Germanium for source regionand Silicon for channel and drain regions. Kane's band-to-band tunneling model hasbeen used to account for the amount of band-to...
