Cottage industries comprise a sub-group of informal sector income generation activities which are conducted in the home environment and organized around families or households. Cottage industry workers may be at risk of exposure to harmful substances associated with their work, and given the lack of separation of cottage industry activities from living spaces, their families and neighbors may s...

A key element for realizing long term sustainable use of any metal will be a robust secondary recovery industry. Secondary recovery forestalls depletion of non-renewable resources and avoids the deleterious effects of extraction and winning (albeit by substituting some effects of its own). For most metals, the latter provides strong motivation for recycling; for light metals, like aluminum, the...

plastic recycling is the process of recovering scrap or waste plastics and reprocessing thematerial into useful products that sometimes differ completely in form from their original state. an importantissue in plastic recovery and recycling is that plastic waste usually contains a variety of plastics that differ intheir physical and chemical properties. separation of recovered plastics into dis...

The recasting of previously casted alloy is a routine procedure used in dental laboratories in order to reduce the cost of permanent partial dentures. The prosthetic “scrap” encompasses the residuals generated in frame dentures casting process e.g. originating from the runners, from casting cones and improperly completed melts e.g. withmisruns, shrinkage porosities and cracks and is frequently ...

We calculate the contribution to the cosmic infrared background from very massive metal-free stars at high redshift. We explore two plausible star-formation models and two limiting cases for the reprocessing of the ionizing stellar emission. We find that Population III stars may contribute significantly to the cosmic near-infrared background if the following conditions are met: (i) The first st...

The purpose of this article is to assess the process electrification transport in Tashkent and forecast some possible consequences until 2027. It has been established that with growth electrification, it achieve hazardous concentrations particulate matter atmospheric air city. A significant relative increase ferrous non-ferrous metal waste (by 1.3...3.6 times), as well scrap tires 1.5 times) al...

This paper presents a novel approach to soft decision decoding for binary linear block codes. The basic idea of this approach is to achieve a desired error performance progressively in a number of stages. For each decoding stage, the error performance is tightly bounded and the decoding is terminated at the stage where either near-optimum error performance or a desired level of error performanc...

Inadequate flexible endoscope reprocessing has been associated with infection outbreaks, most recently caused by carbapenem-resistant Enterobacteriaceae. Lapses in essential device reprocessing steps such as cleaning, disinfection/sterilization, and storage have been reported, but some outbreaks have occurred despite claimed adherence to established guidelines. Recommended changes in these guid...

(GI) endoscopy has been widely used as a clinical diagnostic procedure in Korea since the introduction of the National Cancer Screening Program in 1999. Moreover, the use of endoscopic procedures to treat GI disorders is increasing rapidly. A review article published in 1993 reported 281 instances of pathogen transmission attributed to GI en-doscopy between 1966 and 1992. 1 A recent review foun...

OBJECTIVE To analyze the technical conditions for medical product reprocessing in hospitals. METHODS This was a descriptive study on multiple cases in materials and sterilization centers at four hospitals in the city of Salvador, Southeastern Brazil, in 2010. Semi-structured interviews were conducted and direct observations were made, based on a regulatory model for medical product reprocessi...
