Conservation agriculture practices, such as reduced tillage and the incorporation of cover crops, play a crucial role in improving sustainability organic farming systems. The aim this two-year field trial was to evaluate five different technical itineraries (ST, IN1, IN2, M1, M2) which differed on soil management practices adopted before processing tomato transplantation regarding weed control ...

Ru/Al2O3 nano-catalysts were prepared with impregnation and microemulsion techniques. The supercritical water gasification reaction was performed at 400oC and 5-60 min. Within the tested operation conditions, the reaction residence time of 15 min was the optimum to maximize the H2 yield. It was observed that using microemulsion technique increases the total gas yield significantly. Using microe...

Substantial research shows that high-quality early childhood education programs have a large economic payoff. This payoff is increased earnings for former child participants, increased earnings for parents, and increased earnings for all workers when average worker skills improve. A program package of universal pre-K, combined with child care and parenting support for all low-income families, w...
