A porous medium finite element model of the passive left ventricle is presented. The model is axisymmetric and allows for finite deformation, including torsion about the axis of symmetry. An anisotropic quasi-linear viscoelastic constitutive relation is implemented in the model. The model accounts for changing fibre orientation across the myocardial wall. During passive filling, the apex rotate...
yekta was created in 1981 from crossing between b5 ? m7 and an early maturing palistinian line, in oil seed crops research department of seed and plant improvement institute (spii) at karaj. the pure line of the cross was obtained after five years of selection with pedigree method. preliminary evaluation of the line along with other 31 selected lines was done in 1989 and yekta together with oth...
scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...
Introduction of a suitable vetch as winter crop in cold drylands of Iran is highly important. Line VP-2670 with origin of Turkey was selected from ICARDA nursery during 2002 and was evaluated along with other selected lines and local checks over nine years in different stations and on-farm conditions. VP-2670 with mean 3500 kgha-1 dry biomass over environments, high stability and protein conten...
Industry-wide, there is a trend toward making outcome evaluation a routine part of therapeutic services. Although various multidimensional assessments of outcome are valid and reliable, their methodological complexity, length of administration, and cost often render them infeasible for many service providers and settings. The present article describes the development and validation of an ultra-...
Previous Perspectives in the Journal of General Physiology have considered (a) the different advantages of two models of ion channel permeation and (b) whether ryanodine receptor adaptation might arise from flash photolysis. Each argument, over the choice of model or influence of technique, is an example of a classic scientific dispute. Here we turn to another hoary old problem—the identificati...
The 18th International Conference on Computer Graphics and Interactive Techniques, SIGGRAPH'91, featured a juried selection of virtual reality and hypermedia demonstrations entitled Tomorrow's Realities. Conference participants were treated to twenty-six exhibits which represented the state of the art in virtual world techniques. The SIGGRAPH'91 Conference Proceedings (Computer Graphics, July 1...
When multi-channel EP recordings are used for source localization, the electrode positions have to be determined with respect to a common reference frame. In this paper a method is described for determining the electrode positions on the head. Since it is difficult to fix electrodes accurately at a priori chosen positions, it is better to measure these positions afterwards. For this we have dev...
Novel species of microfungi described in the present study include the following from Australia: Bagadiella victoriae and Bagadiella koalae on Eucalyptus spp., Catenulostroma eucalyptorum on Eucalyptus laevopinea, Cercospora eremochloae on Eremochloa bimaculata, Devriesia queenslandica on Scaevola taccada, Diaporthe musigena on Musa sp., Diaporthe acaciigena on Acacia retinodes, Leptoxyphium ku...
