Sustainability requires a consideration of the social or community dimension as well as ecological integrity and economic efficiency. Further, ecological systems emphasize interaction and interdependence. Definitions of eco-industrial parks have begun to address this by referring to them as communities of business. The paper describes a number of initiatives, particularly in the United States a...

Evidence correlates physical activity, psychological restoration, and social health to proximity to parks and sites of recreation. The purpose of this study was to identify perceived constraints to park use in low-income communities facing significant health disparities, but with proximate access to underutilized parks. The authors used a series of focus groups with families, teens, and older a...

Park design in Iran has followed the traditional European style since the Qajar dynasty. Thefamiliarity of Iranians with the spirit of Persian gardens and the low quality of the newest parks is such that usersprefer ancient geometrical Persian gardens. Today, those responsible for the design of urban green spaces lackingexamples differing from the traditional and thus they are in need of an ade...

A digital filter is a system that uses discrete time signal as input and produce a discrete time output signal for the purpose of achieving a filter objective. Parks-McClellan method provides optimum equiripple approximation to the desired frequency response and has become the dominant method for optimum design of FIR filters. The filter design process can be described as an optimization proble...

Sorghum stemborer species remains key yield limiting factor for sorghum production in the Nigerian semi-arid region. When they can afford, farmers rely almost solely on synthetic insecticides for control. Owing to the misuse and environmental and health challenges attributed to the use of synthetic insecticides, a two-year field study was carried out at the University of Maiduguri Research Farm...

The importance of natural disturbances for biodiversity is well-documented in the disturbance ecology literature. Natural such as fire, wind, and flooding strongly influence ecosystems by creating short long-term ecological processes. Conservation management protected areas should consider since shifts are, a perspective, necessary to maintain high biodiversity. purpose this study explore how i...
