This paper deals with the economic optimization of flotation circuits. A model for estimating the optimum number of cells in a bank, to give a definite target recovery, as well as the volume of each cell is developed. A hypothetical

The present study examines some physical, biological, and socioeconomic characteristics of 32 homegardens randomly selected from four villages representing different agro-ecological conditions, variable population densities, and market opportunities. The study results suggest that large numbers of plant and animal species occupy homegardens, and their composition and intensity of cultivation vary directly with the household physiologic density and access to urban markets, and inversely with environmental constraints to agriculture. Homegardens form the activity space for household women and children, who perform most homegarden farming tasks. Uses of home generated inputs at no or low cost make homegardens economically more efficient and sustainable compared to non-homegarden rice farming. In the context of the intensive subsistence agriculture patterns that dominate Bangladesh, homegardens contribute significantly to smallholder household income.

Multi-protocol label switching (MPLS) technology is the most popular candidate for implementing VPLS because it supports traffic engineering (TE) functionality over the established label switching paths (LSP). However, MPLS's TE support is provided over point-to-point

This allowed Service Providers (SP) to increase the number of admitted requests by taking advantage of the statistical multiplexing behavior of such traffic. Usually, each VPN connection has different QoS requirements such as delay and violation probability bounds. Also, each
