Abstract:
... The aroma in rice and its products is one of the important quality characteristics. It is contributed by more than 500 different volatile compounds and the extraction and quantification of aroma compounds are equally essential, determining the threshold of aroma. Till date,a complete review of the aromatic consideration of rice is lacking in the literature. Therefore, thepresent paper is prepared ...

Abstract:
... In an open channel, a vegetation patch increases local flow resistances, which impacts velocity fields inside and outside the patch. A series of experiments was performed to investigate the longitudinal evolution of velocities in a channel with an emergent vegetation patch. Near the upstream edge of a patch, lateral flow adjustments led to decreased velocity inside the patch and increased velocity ...
