Degraded floodplains and valley floors are restored with the goal of enhancing habitat for native fish aquatic-riparian biota protection or improvement water quality. Recent years have seen a shift toward “process-based restoration” that is intended to reestablish compromised ecogeomorphic processes resulting from site- watershed-scale degradation. One form process-based restoration has develop...

A novel diacylglycerol-based galloyl structured lipid, 1,2-dipalmitoylgalloylglycerol (DPGG), was synthesized using the enzymatic transesterification of propyl gallate (PG) and tripalmitin under solvent-free condition. An immobilized commercially available food-grade Candida antarctica lipase B, Lipozyme® 435, used as biocatalyst. The reaction variables that affect yield DPGG were optimized a 3...

Biginelli-type reaction was developed by means of a three-component condensation of analdehyde, ethyl acetoacetate, urea or thiourea and nano alumina sulfonic acid (Al2O3-SO3H)(NASA) as catalyzed. It is carried out under different conditions. In all conditions, the desiredproducts are obtained in high yields after relatively short reaction times. Nevertheless, thereactions proceeded faster and ...
