it was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (ap). it seems that some other types of mechanisms must be involved in ap propagation. in this article, we...

In class, we have assumed that the concentration, the number of free monomers in the volume, does not change in time, C = n/V = const. Assume now, that no new monomer is added to the solution as the filament grows and therefore C = C(t). • Sketch the evolution of the free monomer concentration C as a function of time t. • Determine the tangent to the curve at t → 0. • Determine the asymptotic v...

Toxicity of the organophosphate, diazinon was studied in grass carp (Cetenopharyngodon idella) weighing 5±1.0g, under static water quality condition at 16°C. Also, some hematological and biochemical variables of fish weighing 50±5.0g were studied 12 hours post-exposing fish to the toxicant at sublethal concentration of 5.6mg/L at 16°C. Values of 18.19, 17.21, 16.68, and 15.13mg/L, were obtained...

in this study, production of fermented functional beverage based on the mixture of carrot, beet and apple juices using the lactobacillus casei was carried out. factors of consumption of reduction sugars, brix and bacterial growth were examined after fermentation and during the storage for 28 days and at 4˚c. to produce probiotic fermented mixture of carrot, beet and apple juices and lactobacill...

the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...
