Manikins are essential in teaching and practicing CPR. Industry as provided them in different degrees of complexity. Costs are irectly proportional to sophistication and in some cases it might e a limiting factor especially among poor people. Training programs in emergencies have been developed for umble populations, and have included the use of a CPR dummy ade with simple materials – in compar...

A simple and relatively cheap locally-assembled light trap was used to sample pre-settlement fish larvae in the Malindi Marine Park, Kenya, for two years. The trap was assembled locally using a water dispenser bottle, plastic bottle necks, buckets, 12V rechargeable alkaline batteries and a diver’s dry box. The light unit consisted of a 12 V rechargeable alkaline Jacob’s battery that powered a 1...

Bisphenol A, an estrogen mimicker, is found in the commonly used plastic, polycarbonate. Zebrafish embryos were raised in water that had been heated in polycarbonate water bottles by either microwaving for 5 minutes, or boiling for one hour. Near total mortality was seen in 7 days for the embryos growing in bottle-microwaved water, and 9 days for those raised in bottle-boiled water. Zebrafish e...

taining 300–3,000 mL of water), one thermal bottle (250 mL), one plastic bottle (50 mL), and one bucket (2,500 mL). Larvae were placed in plastic bags and transported to CIP laboratories, where they were allowed to emerge to adults during 17 days. The fourth instar larval and pupal exuvias were fixed and identified to species according to Darsie (7) and Superintendência de Campanhas de Saúde Pú...

serum to thaw completely during centrifugation. Further experiments have shown that protein and electrolytes can be removed rapidly from frozen serum or urine by centrifugation, at relatively low speeds with little or no visible evidence of thawing. Part of the sample (25 ml.) of urine from a nephritic dog was placed in the barrel of a '20 ml.' plastic syringe suitably plugged at the exit and f...
