Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. It has some germicidal properties and may remove contaminants mechanically. When it is applied to tissues catalase causes its rapid molecular decomposition with the release of oxygen bubbles (1 ml of hydrogen peroxide 3% (10 vol) will release 10 ml oxygen).' Irrigation under pressure or into enclosed body cavities, ...

In recent years, irrigating agricultural land with wastewater has become a major wastewater management practice. Irrigation has replaced much of the discharge to streams and conventional primary and secondary waste treatment for food processing wastewater (4, 11, 12, 13). Irrigating agricultural land for treatment and disposal of the food processing wastewater is a good practice if the wastewat...

Multiple cost sharing rules often coexist in seemingly identical environments. We use shared irrigation costs as a context for examining the extent to which the structural environment explains the selection of a cost-sharing rule. We find that environmental factors affecting the costs and benefits derived from irrigation, as well as those determining the distribution of irrigators along the irr...

To determine the in vitro allelopathic effect of aqueous extract Calathea lutea (Aubl.) E.Mey. ex Schult. (bijao) on initial growth Lactuca sativa L. (lettuce) variety White Boston. An at 15% w/v was prepared with each part bijao plant (stem, leaf, and root), it left to stand for 48 hours, then extracts 2, 4, 6% concentrations were obtained by dilution. 10 lettuce seeds/petri dishes sown, irrig...
