The growth of a mouse leukemia virus in an established mouse cell line was examined after the line became contami nated with an unidentified Mycoplasma species. The con taminated cultures grew well in small plastic cultures dishes, but they could not be propagated in larger roller bottles unless the growth medium was changed frequently. Cells from A/ycop/flÃ-/MÃ-J-contaminated and Mycoplasma-fr...

In order to utilize or to extract the shape information of objects in an image for recognition, classification or retrieval, a method for representing a shape is needed. In this paper, a work on representing plastic bottle shape using morphological based approach for an automated classification is reported. Morphological operations are used to describe the structure or form of an image. There a...

One million plastic bottles is currently consumed every minute in the world. This consumption trend expected to further increase thereby worsening problem of pollution across globe. Mauritius also not left unaffected by and an bottles. Although recycling encouraged on island, low rate has been recorded (40%). In this context, research attempts enhance solid waste management methods Mauritius, m...

A suspension of Ketawaspreparedby trypsinization of stock cultures in Blake bottles. After determining the cell count with a hemocytometer the suspension was diluted with medium to give a c@int of' 75,000 cells per 0. 9 ml. Using an automatic pi pette, 0. 9 m:1@. of the Hela suspension was delivered into each of the cups of the plastic panel and the test compound added in 0.1 ml. saline or in 0...

Abstract Plastic bottle waste can damages the environment in sea and land. bottles are non-biodegradable, it takes decades to decompose. The author got a creative idea utilizing plastic into eco friendly wayang design. research using qualitative methods prototype designs as result of research, this program directed at process responding environmental sustainability growing childrens awareness u...

pet wastes from post consumer bottles can be chemically degraded into some compounds such as oligomers and some monomers such as bishydroxy ethyl terephthalate(bhet)by some catalysts(zn, co, pb and mn acetates) in ethylene glycol at 189 oc under n2 atmospheric pressure. the compounds obtained in the chemical depolymerization can be used as plasticizers in paint, fibbers, rubbers and plastic ind...

Antimony is a regulated contaminant that poses both acute and chronic health effects in drinking water. Previous reports suggest that polyethylene terephthalate (PET) plastics used for water bottles in Europe and Canada leach antimony, but no studies on bottled water in the United States have previously been conducted. Nine commercially available bottled waters in the southwestern US (Arizona) ...

BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...
