The development and testing of a discrete model describing the dynamic process of tissue growth in three-dimensional scaffolds is presented. The model considers populations of cells that execute persistent random walks on the computational grid, collide, and proliferate until they reach confluence. To isolate the effect of population dynamics on tissue growth, the model assumes that nutrient an...

in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...

Fronts, propagating into an unstable state phi=0, whose asymptotic speed v(as) is equal to the linear spreading speed v* of infinitesimal perturbations about that state (so-called pulled fronts), are very sensitive to changes in the growth rate f(phi) for phi<<1. It was recently found that with a small cutoff, f(phi)=0 for phi< epsilon, v(as) converges to v* very slowly from below, as ln(-2) ep...

The super-growth approach for carbon nanotubes synthesis is frequently used to boost the growth rate, catalyst lifespan, and height of vertically aligned nanotubes. elimination amorphous from particles, commonly made iron, by injecting water vapor into a chemical deposition process can enhance purity, alignment, prevent partial oxidation metallic catalyst. We present development modified growth...

current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mm) of different salts including nacl and na2so4 on germination and initial growth phase of halostachys caspica were studied. the experimental design was completely randomized design with three replications. characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

Introduction: Several factors such as diseases, medications and humoral agents can delay or speed up wound healing process. Because of the limited information about the hormonal changes during wound healing, in this study the relationship between serum levels of growth hormone, insulin and cortisol and wound healing in normal and diabetic rats was evaluated. Methods: Male Wistar rats )weigh...

The impact of two principal parasitic digenetic trematodes, Meiogymnophallus minutus and Himasthla spp., on the growth (weight and length) of the cockle, Cerastoderma edule, in Arcachon Bay (France) was studied. The experiment was conducted in the land-based mesocosms. The velocity of infestation with both trematodes was far more rapid during summer in the cockles already parasitized with these...
