The air pollution-related health benefits of interventions to reduce indoor air pollution from cooking and heating with solid fuels are evaluated in South and South-east Asia, Africa, and the Americas using generalized cost-effectiveness methodology. Three scenarios are assessed: 1) providing access to cleaner fuels, (2) providing access to improved stoves, and (3) providing part of the populat...
The flotation circuit in Sungun copper plant consists of two column flotation cells as cleaner, having fixed-spargers system. To achieve the expected aims in flotation step, there are serious operational challenges such as: fast choking of the static mixers, boiling problem, burping phenomena and pulp overflow to concentrate lander, maintenance and control problems. An attempt was exerted by im...
We determine the three-neutrino mixing and mass parameters that are allowed by the solar and atmospheric neutrino data when vacuum oscillations are responsible for both phenomena. The global fit does not appreciably change the allowed regions for the parameters obtained from effective twoneutrino fits. We discuss how measurements of the solar electron energy spectrum below 6.5 GeV in Super-Kami...
A coding theorem is proved for the secret sharing communication system (SSCS) with two Gaussian wiretap channels. This communication system is an extension of both the SSCS with two noiseless channels and the Gaussian wiretap channel (GWC). The admissible region of rates and security levels for the SSCS with two GWC’s is described by the capacities and secrecy capacities of two GWC’s.
