in this investigation, a facile and green sonochemical route has been developed for the synthesis of 2-ketomethylquinolines by using 2-methylquinolines and several acyl chlorides in the presence of nanocrystalline mgal2o4 as an efficient heterogeneous catalyst. the combination of nanocatalyst and ultrasonic process afforded corresponding ketomethyl quinolines in shorter reaction durations, and ...

Skeletal muscle plays a key role in postural retention as well as locomotion for maintaining the physical activities of human life. Skeletal muscle has a second role as an elaborate energy production and consumption system that influences the whole body's energy metabolism. Skeletal muscle is a specific organ that engenders a physical force, and exercise training has been known to bring about m...

A facile and efficient synthesis of bis(indolyl)methanes derivatives (3a-u) was reported via a condensation reaction of aldehydes and indole in the presence of by silica-supported-3-(triethoxysilyl) propane-1-ammonium chloride catalysis under solvent free conditions. We studied the reaction in different conditions and optimized. The use of just 0.02 g of (silica gel-ammonium salt) is sufficient...

average wealth? Is physical hardship, or over-protection, a 1 w a y s harmful? If not, at what point do they become harmful? How much of what appears to be the effect of poverty or wealth is actually due to community attitudes? The questions that must be put to the social-psychologist are endless. What effect have national, or local, standards of excellence on character development? How do thes...
