Establishing trees in agricultural bottomlands is challenging because of intense competition, flooding and herbivory. A summary is presented of new practices and management systems for regenerating trees in former agricultural fields in the eastern USA. Innovations have come from improvements in planting stock and new silvicultural systems that restore ecological function more quickly than trad...
in order to investigate the response of cotton cultivars (gossypium hirsutum l.) to conventional-cropping and double-cropping systems a field experiment was conducted as split plot based on randomized completely block design with three replications at gonabad agriculture and natural resources research station during growing season of 2009-2010. the treatments included of recommended planting da...
Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...
Information Systems/ Information Technology (IS/IT) signifies an organization's use of computer systems for project completion and goal realization. Strategic planning has, for long, empowered the organizations to fully utilize the information systems and technologies at their disposal. Research findings, however, indicate how complex and fraught with setbacks this kind of planning can be. With...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Forest-based industries represent a major economic sector in Canada and account for a large proportion of its exports. Planning problems in forestry cover a wide scope of activities ranging from planting and harvesting to road building and transportation. Furthermore, in many of these activities, it is critical to pay attention to important environmental issues, as well as to company-specific g...
intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
