Deep Pipe Irrigation, David A. Bainbridge

David A Bainbridge

Deep pipe irrigation uses a vertically placed section of pipe to deliver water to the roots of plants. This reduces evaporation and increases water use efficiency. Deep pipes can be filled by hand, drip or rainwater catchment.

Planting Desert Sites, David A. Bainbridge

David A Bainbridge

Desert planting requires great care in preparing plants, handling plants and planting. With proper consideration of soil, climate and water availability plants can be established despite severe conditions of high temperatures, high winds, herbivory and lack of water.

Comparative Study Of Various Pretreatment Reagents On Rice Husk And Structural Changes Assessment Of The Optimised Pretreated Rice Husk, Teck Nam Ang Dr., Gek Cheng Ngoh Dr, Adeline Seak May Chua Dr

Teck Nam Ang Dr.

The performance of alkalis (NaOH and Ca(OH)2) and acids (H2SO4, HCl, H3PO4, CH3COOH, and HNO3) in the pretreatment of rice husk was screened, and a suitable reagent was assessed for subsequent optimisation using response surface methodology. From the assessment, HCl that hydrolysed rice husk well was optimised with three parameters (HCl loading, pretreatment duration, and temperature) using Box-Behnken Design. The optimised condition (0.5% (w/v) HCl loading, 125oC, 1.5 hours) is relatively mild, and resulted in ~22.3 mg TRS/ml hydrolysate. The reduced model developed has good predictability, where the predicted and experimental results differ by only 2%. The comprehensive structural characterization …
