We evaluated the performance of the BD Max MRSA XT assay for use with different swab types. The 90% detection rates (95% confidence intervals) were 387 (97 to 1,551), 877 (238 to 3,230), 986 (183 to 5,287), 1,292 (328 to 5,078), 2,400 (426 to 13,518), and 5,848 (622 to 55,021) CFU/swab for Liquid Stuart, Liquid Amies, dry, Amies Gel without charcoal, ESwab collection, and Amies gel with charcoa...

Global demand for charcoal is increasing mainly due to urban population in developing countries. More than half the global population now lives in cities, and urban-dwellers are restricted to charcoal use because of easiness of production, access, transport, and tradition. Increasing demand for charcoal, however, may lead to increasing impacts on forests, food, and water resources, and may even...

Bone charcoal, a mixed adsorbent containing around 10% carbon and 90% calcium phosphate, is mainly produced by thermal treatment of bones. Structurally, calcium phosphate in bone charcoal is in the hydroxyapatite form [1-2]. Traditionally, bone charcoal has been used to remove color in sugar solutions in the sugar refining industry. Recent studies use bone charcoal to adsorb radioisotopes of an...

This paper assigns monetary values to commercial production of charcoal (using traditional earth kilns) in the miombo woodlands surrounding Kitulanghalo Forest Reserve in eastern Tanzania, through cost–benefit analysis (CBA). Charcoal is the most commercialised resource in the study area and the net present value (NPV) for the charcoal business over a 15-year period was US$ 511 ha. The profit f...

Timber procurement and the use of woodlands are key issues in understanding the open landscapes of the Norse and Medieval periods in the North Atlantic islands. This paper outlines evidence for the timing and mechanisms of woodland use and deforestation in an area of southern Iceland, which is tracked through the mapping and analysis of charcoal production pits. Precise dating of the use of the...

1. The ability of activated charcoal, treated in differing ways with poly(hydroxyethylmethacrylate), to adsorb paracetamol was studied. 2. Activated charcoal was coated with 2,4 or 10% by weight of poly(hydroxyethy1methacrylate). Neither the percentage by weight (2, 4 or 10%) coating of activated charcoal by the polymer nor the procedure used to apply the coat affected the total adsorption of p...
