Supporting and standardizing the development of new employment forms effectively protecting labor rights interests flexible groups in Chengdu Chongqing are important measures to achieve “stabilizing employment” “protecting people’s livelihood”, which is also an embodiment “Planning Outline for Circle Construction”. Based on analysis main problems faced by interests’ protection laborers form Cho...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

Efficient monitoring and control of Waste Water Treatment Plant (WWTP) has turned into an important public issue as the cost of electricity continues to grow and the quality requirement of processed water tightens. A Microbial Fuel Cell (MFC) is a bio-electrochemical system that drives a current by mimicking bacterial interactions found in nature. Self-powered Wireless Sensor Networks (WSNs) ar...

The increasing awareness that there are limits to the availability of nonrenewable resources, as well as that there are limits to the biosphere’s ability to absorb wastes, are at the basis of the growing interest about Microbial Fuel Cells (MFCs) technology, with particular regards to their application to wastes treatment. MFCs, in fact, couple the direct electric power production to the degrad...

As the world’s population approaches seven billion people, it is vital to find methods of livestock production, energy generation, and organic waste utilization that are sustainable for the future. Livestock manure has long been valued as a fertilizer and soil amendment, and more recently as a methane producer for heat and power via anaerobic digestion (AD). Microbial fuel cells (MFC) may offer...

Maximum power densities by air-driven microbial fuel cells (MFCs) are considerably influenced by cathode performance. We show here that application of successive polytetrafluoroethylene (PTFE) layers (DLs), on a carbon/PTFE base layer, to the air-side of the cathode in a single chamber MFC significantly improved coulombic efficiencies (CEs), maximum power densities, and reduced water loss (thro...

Scaling-up of microbial fuel cells (MFCs) for practical applications requires compact, multiple-electrode designs. Two possible configurations are a separator electrode assembly (SEA) or closely spaced electrodes (SPA) that lack a separator. It is shown here that the optimal configuration depends on whether the goal is power production or rate of wastewater treatment. SEA MFCs produced a 16% hi...

Microbial fuel cells (MFCs) are a type of fuel cells that use bacteria as biocatalyst to oxidize an organic substrate to release electrons, which can be harvested in an external circuit to produce electric energy. This technology hold the potential to help overcome energetic problems and at the same time treat waste water more efficiently than the current employed techniques. Despite all this p...

The well-known use of the microbiological process of anaerobic digestion (AD) to generate biogas (mixture of methane and CO2) is now widely implemented for the production of renewable energy worldwide. In Russia, however, this is not the case despite huge amounts of organic wastes (OW) suitable for AD. This paper firstly inventories major flows of OW from various sectors of the national economy...

Resource recovery and recycle of organic waste is a major concern now-a-days all over the world. This present study deals with the Microbial Fuel Cells (MFC) using kitchen garbage to produce electricity as well as recycle of organic waste and its potential use in Bangladesh. A rectangular acrylic container (10 x 10 cm) was used as the cell. The container was filled with well mixed kitchen garba...
