Abstract Genetically engineered chymosin from the tree shrew ( Tupaia belangeri chinensis ) has been obtained and partially characterized for first time. The target enzyme was produced in Escherichia coli , strain BL21(DE3). It shown that recombinant coagulates cow milk Bos taurus ). total specific milk-clotting activity of 0.7–5.3 IMCU/mL 8.8–16.6 IMCU/mg. nonspecific proteolytic relation to b...

Resonant response of water waves in a narrow gap, the so-called gap resonance, is hydrodynamic phenomenon with practical applications. When coupled to body motions, physics becomes rather complicated, involving fluid resonance and damping that determines amplitude. Gap resonances between two identical elongated bodies, one held fixed other floating, are investigated experimentally for unidirect...

in this study 121 prescapular, prefemoral and popliteal lymph node of male healthy camel from mashhad abattoir were collected. after collecting of specimens factors such as: length, width, thickness, weight, volume and density of each lymph node were measured by caliper device. all factors were analyzed and compared using excel program. it was revealed that, normal dimensions of right prescapul...
