hospital wastes are one of most important environmental problems because of their hazardous, toxic and pathogenic characteristics. the aims of this study were to identify and measure the amount of hospital wastes and classify of them according to who criteria in amirolmomenin(as) hospital and shahid rajaei policlinic in ahwaz, sw of iran. this research was a field-descriptive study. initially, ...

Lean is a systematic approach to identify and eliminate non-value-added activities or waste through continuous improvement process. While traditional lean manufacturing focuses on the activities within a single organization, lean supply chain consists of the same processes, but it views these processes over multiple organizations. This research addresses an important yet under-studied area – le...

Blood is a rich source of iron and proteins of high nutritional and functional quality. Because of the high protein content of blood, generally about 18% [1], it is sometimes referred to as “liquid protein” [2]. It has been estimated that the approximately 1,500,000 tons of porcine blood produced yearly in China has a protein content equivalent to that of 2,000,000 tons of meat or 2,500,000 ton...

This work compares two electrode materials used to mineralize phenol contained in waste waters. Two disks covered with either boron doped diamond (BDD) or PbO2 were used as anodes in a one compartment flow cell under the same hydrodynamic conditions. Efficiencies of galvanostatic electrolyses are compared on the basis of measurements of Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD...

Lean production, which has revolutionary production management and practice manner, is the third milestone of human industrialization history. Its key point is to eliminate waste in all aspects of a firm’s production activities through establishing production system with high agility. It represents the tendency of modern manufacturing industry. It has been credited as the standard production ma...

Manufacturing organizations have used Lean management principles for years to help eliminate waste, streamline processes, and cut costs. This pragmatic approach to structured problem solving can be applied to health care process improvement projects. Health care leaders can use a step-by-step approach to document processes and then identify problems and opportunities for improvement using a val...

Use of conventional organic solvents often leads to the formation of hazardous waste, the disposal of which is a matter of environmental concern. Carbon dioxide is considered to be a green reaction medium and a good replacement for conventional organic solvents as it is benign and leads to elimination/reduction of hazardous wastes. Use of CO2 at near/above critical conditions has several additi...

Abstract Progress in particle accelerator technology makes it possible to use a proton accelerator to produce energy and to eliminate nuclear waste efficiently. The Energy Amplifier (EA), proposed by Carlo Rubbia and his group, is a subcritical fast neutron system driven by a proton accelerator. It is particularly attractive for destroying, through fission, transuranic elements produced by pres...

An operations strategy should be based on a strong systematic and standardized way of working combined with empowered shop floor teams who drive continuous improvement in that standardized work. OEE data on machine performance is a key starting point for teams to understand there equipment losses and to establish improvement programs to eliminate them. We find that the implementation of OEE is ...

Along with economic development, cities are increasingly congested in China. In order to eliminate peak-hour congestion, many cities establish priority lanes, commonly bus lanes. Although priority lanes could help Local Authorities gain its short-term management objectives, at the same time, it would greatly infringe on the legitimate rights of other vehicles and waste the scarce road resources...
