The field of compressed sensing has shown that a sparse but otherwise arbitrary vector can be recovered exactly from a small number of randomly constructed linear projections (or samples).

Aluminium hydroxide is used to prevent hyperphosphataemia in patients undergoing dialysis, but many standard preparations are unpalatable. In this study hydrated aluminium sucrose was suspended in synthetic cream and used as a biscuit filling. Six patients undergoing dialysis took part in five five-week study periods comparing different forms of treatment. No significant difference was found be...

Several substances/food baits and admixtures thereof were tested in a perspex trap, treated with insecticide [email protected] mg/cm2. Bioefficacy for housefly trapping was evaluated. Combination of ingredients was found to be more effective than individual ingredients. A combination of some easily available and cheap ingredients were employed for field trials. The admixtures of milk powder, dog b...
