Abstract:
Two hypotheses for the mechanism of anode break excitation in cardiac tissue are electrotonic interaction between adjacent regions of depolarization and hyperpolarization, and a hyperpolarization-activated membrane current, if. We incorporate membrane kinetics proposed for if into the bidomain model with unequal anisotropy ratios. During unipolar stimulation, we find that: (1) The mechanisms of cathode make, cathode break, and anode make excitation are insensitive to if. (2) Both electrotonic interactions and if contribute to anode break excitation. In our simulations, if makes the dominant co

An experimental investigation of the effect of two different type of stitches viz., lockstitch and chainstitch at the seat seam of trouser for military armed forces has been reported. Performance of chainstitched seam is found to be much better as regards lower value of force at low level of strain, higher value of force at break, strain at break and work of rapture. In general with the change in thread linear density, greater improvement in seam strength, seam strain at break and work up to fracture are obtained in case of chainstitched seam.

Nanocomposites based on segmented poly(urethane urea) were prepared by reacting a poly(diisocyanate) with diamine-modified Laponite-RD nanoparticles that served as a chain extender. The nanocomposites were prepared at a constantNH2to NCO mole ratio of 0.95, while varying the fraction of diamine-modified Laponite relative to the free diamine chain extender. Compared to neat poly(urethane urea), all nanocomposites showed increased tensile strength and elongation at break. As Laponite loading increased, tensile properties passed through a maximum at a particle concentration of 1 mass%, at which a

Abstract Patterns from hurricane damage indicate that longleaf pine is more windfirm than loblolly pine. Tree windfirmess has been attributed to many factors including species and material properties like wood strength and stiffness. Because longleaf pine wood is stronger and stiffer than loblolly pine wood, this study used static winching methodology to see if these properties account for differences in wind firmness by measuring bending force required to break stems (MMAX).

In the heat of this debate, the question of Heidegger's place in relation to that tradition in general and to Cartesianism in particular has been neglected.

Abstract Design of moorings with chain sections typically assume a level of uniform through-life corrosion and wear. The associated reduction in strength is, in simplistic terms, estimated by assuming a smaller as-new chain diameter. Where inspections show chain links to have localised material loss the resultant reduction in strength is harder to account for as it is dependent on the volume, shape and location of the loss. Discard criteria found in design standards are necessarily conservative as they must encompass the most damaging combinations of size, shape, and location of material loss.
