A heat transfer model was developed for a new non-electric infant’s transport incubator. The source of heat comprises a super saturated solution of Sodium Acetate and a metal disk (activator) in a plastic container. Estimating the number of the chemical bags required for different ambient temperature was the goal. First the quantity of heat generated by the chemical was appointed through experi...

Development of protocols for storing desiccated cells at ambient temperatures offers tremendous economic and practical advantages over traditional storage procedures like cryopreservation and freeze-drying. As a first step for developing such procedures for adult stem cells, we have measured the post-rehydration membrane integrity (PRMI) of two passages, Passage-0 (P0) and Passage-1 (P1), of hu...

OBJECTIVES To determine Clostridium difficile (C. difficile) prevalence on retail surfaces and shoppers plastic bags. METHODS From 20 June to 10 August 2011, in a cross-sectional epidemiological study, 17 supermarkets from 2 cities, Albaha and Altaif, Saudi Arabia were sampled. A total of 800 samples, which comprised 200 samples per surveyed surface, were studied. These included baskets, trol...

This paper aimed to evaluate the effects of storage periods on the conservation of Pachyrhizus ahipa roots at different temperatures and packaging materials. The roots were harvested, washed, packed in PVC, plastic bags, without wrappings (control) and stored in polystyrene trays in refrigerators, or cold chambers, or at room temperature. Total titratable acidity (TTA), total soluble solids (TS...

“It was sad to see the empty bag Blown about like a dirty rag” A Summer Morning Walk By Patrick Kavanagh (1904-1967) Introduction: In March 2002, the Irish Government introduced a 15 Euro cent environmental levy on all shopping plastic bags, previously provided free of charge to consumers at points of sale. The motivation for such was primarily to reduce the consumption of plastic bags and the ...

The effects of aeration through lid filters on the hyphal growth of Lentinula edodes (oak mushroom) in sawdust cultivation bags were investigated. The aeration treatment levels were traditional 27 mm hole cotton plugs, cotton balls and combinations of seven hole sizes × two hole positions (up and under) in the lids covering plastic bags containing 1.4 kg sawdust medium at 63% moisture that had ...

The objective of this study was to test the hypothesis that ultrasound covers and sonographic gels, used during vaginal ultrasound, are toxic for mouse embryonic development in vitro. A prospective randomized design was used on pronucleate ova of F1 hybrid CBA x C57Bl female mice. The mice were superovulated with pregnant mare's serum gonadotrophin and human chorionic gonadotrophin and mated wi...

Plastic is cheap, ubiquitous and persistent. In 2010 the world produced 265M tonnes. Annual output is increasing with new uses and varieties augmenting demand. Plastic persists for centuries, much of it finding its way into coasts and waterways. Approximately 80% of marine debris is plastic (mostly bags and bottles), accumulating through spillage, runoff, dumping and discharge; with varied envi...
