Root hairs are a low-cost way to extend root surface area (RSA), water and nutrient acquisition. This study investigated to what extend variation exists for root hair formation in rice in dependence of genotype, phosphorus (P) supply, growth medium, and root type. In general, genotypic variation was found for three root hair properties: root hair length, density, and longevity. In low P nutrien...

In the present work, we investigate the applicability of the method of fundamental solutions for the solution of boundary value problems of elliptic partial differential equations and elliptic systems. More specifically, we study whether linear combinations of fundamental solutions can approximate the solutions of the boundary value problems under consideration. In our study, the singularities ...

The effect of the box shape on the dynamic behavior of proteins simulated under periodic boundary conditions is evaluated. In particular, the influence of simulation boxes defined by the near-densest lattice packing (NDLP) in conjunction with rotational constraints is compared to that of standard box types without these constraints. Three different proteins of varying size, shape, and secondary...

We describe a technique which permits a uniform construction of a number of low rank bundles, both known and new. In characteristic two, we obtain rank two bundles on P5. In characteristic p, we obtain rank two bundles on P4 and rank three bundles on P5. In arbitrary characteristic, we obtain rank three bundles on P4 and rank two bundles on the quadric S5 in P6.

In the present paper, we continue our investigation of optimal control problems for the bidomain equations. In a previous work [ Kunisch/Wagner 11 ] , control problems involving the monodomain approximation of the bidomain system have been considered. Well-posedness of the problem formulation was proved, and first-order optimality conditions were derived. Turning now to the study of optimal con...

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...
