Aminopolycarboxylate chelants (APCs) are extremely useful for a variety of industrial applications, including the treatment of toxic metal-contaminated solid waste materials. Because non-toxic matrix elements compete with toxic metals for the binding sites of APCs, an excess of chelant is commonly added to ensure the adequate sequestration of toxic metal contaminants during waste treatment oper...

Abstract Industrial washing is essential in manufacturing and many other technological fields. Nowadays, steam the most common technique. However, it involves chemical solvents which are potentially noxious for environment difficult to be disposed of. Therefore, there a growing demand alternative techniques that would ensure low operating costs, extensive productivity, high efficiency, environm...

This article covers the development of thermoplastic extrusion films made poly(vinyl acetate) (PVA) and poly(butyl methacrylate) (PBMA) for use as an inner layer in metal-polymer-metal multiple-layered vibro-damping materials that can work contact with water. The effect amount introduced plasticizer on dynamic properties polymer PVA PBMA is studied example plasticizers from group esters dicarbo...

Inadequate hand washing by food workers is an important contributing factor to foodborne disease outbreaks in retail food establishments (RFEs). We conducted a survey of RFEs to investigate the effect of hand washing training, availability of hand washing facilities, and the ability of the person in charge (PIC) to describe hand washing according to the Minnesota Food Code (food code) on worker...

Mere familiarity does not necessarily produce understanding. It is perfectly possible to know something (or someone!) all your life and still never really comprehend what you're dealing with. Like the Irishman in the old joke who received a brand-new toilet from his American cousins: He used the bowl for a foot washer, the lid for a breadboard, and the seat for a frame around the Pope's picture.

Abstract While Lee and Schwarz propose grounded procedures of separation as an explanation for physical cleansing in various domains (e.g., washing one's hands), we suggest that can also account behavioral aimed at consciences polishing reputations. We discuss this extension terms degrees cleansing, motivations, intentions behind social settings.

The mechanical and thermal properties of injection-molded recycled polyethylene were studied, specifically with respect to the influence large-scale washing melt-compounding from post-consumer packaging waste. Three types materials studied: those taken after sorting, sorting washing, melt-compounding, including melt-filtration, all a material flow. further processed on laboratory scale compared...
