Several descriptions of basically one transformation technique, viz. accumulation, are compared. Their basis, viz. the associativity and the existence of a neutral element inherent in a monoid, is identiied.

Reproductive biology of three important small indigenous fish species mola (Amblypharyngodon mola), punti (Puntius sophore) and chela (Chela cachius) was studied for 12 months from January to December, 1999 in the Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh. Gonadosomatic index (GSI) and ova diameter were analysed to determine their reproductive cycle. Thr...

Arthritic lesions have been frequently diagnosed in the fossil record, with spondyloarthropathy (a type of erosive and pan-mammalian arthritis) being one of the most common types described to date for mammals, though not restricted to this group. Here, we identify spondyloarthropathy in fossil bones from the late Pleistocene in Brazil assignable to a large glyptodont individual. Bone erosions i...

The antioxidant activities of the crude hydro-alcoholic extract (CE) and its four fractions viz. methanol (MF), ethyl acetate (EF), n-Butanol (BF), and precipitated aqueous (PAF) of A.racemosus roots tested decreased in the order of EF > MF > CE > BF > PAF when investigated by DPPH free radical scavenging assay. Under iron induced lipid peroxidation almost similar results were observed except t...
