Synthesis of naturally occurring partial methyl ethers of myricetin

The synthesis of combretol, annulatin, and europetin-naturally occurring partial methyl ethers of myricetin-is described. Condensation of 2, 4, 6-trihydroxy-ω-methoxyacetophenone with tri-O-methyl galloyl chloride or tri-O-benzyl galloyl chloride furnished the appropriate 3-methoxyflavones, which by a series of reactions furnished the natural myricetin derivatives

National and firm-level drivers of the devolution of HRM decision making to line managers

Multinational companies must understand the influences on responsibility for managing people so that they can manage talent consistently thus ensuring that it is transferable across locations. We examine the impact of firm and national level characteristics on the devolution of HRM decision making to line managers. Our analysis draws on data from 2335 indigenous organizations in 21 countries. At the firm level, we found that where the HR function has higher power, devolution is less likely. At the national level, devolution of decision making to line management is more likely in societies with more stringent employment laws and lower power distance

Synthesis, characterisation and evaluation of polyamide membrane

The synthesized polyamide has functional amino and carboxyl groups. The polymer has been characterized by using IR and 1H NMR. The membrane porosity has been determined by SEM. The evaluation of membrane has been done by using "Reverse Osmosis Test Cell" (Osmonics).The salt rejection(efficiency)and product water output rate (flux)have also been determined for different membranes with LiNO3/LiCI combinations.</span
