Dwarf maize (Zea mays L.), a mutant deficient in gibberellin synthesis, provides an excellent model to study the influence of gibberellin on biochemical processes related to plant development. Alterations in the chemical structure of the cell wall mediated by gibberellin were examined in seedlings of this mutant. The composition of the walls of roots, mesocotyl, coleoptile, and primary leaves o...

Let µ be the self-avoiding walk connective constant on Z d. We show that the asymptotic expansion for β c = 1/µ in powers of 1/(2d) satisfies Borel type bounds. This supports the conjecture that the expansion is Borel summable.

Cavity expansion is a fundamental theoretical problem in geomechanics. For the cylindrical cavity problem, derivations of solutions are usually based on assumption that soil subject to plane strain condition. However, this untrue for pressuremeter tests. This study first derived equilibrium equation under constant vertical stress Then, was solved modified Cam clay soils with different overconso...

We develop a perturbative expansion which allows the construction of nonabelian self-dual SU(2) Yang-Mills field configurations on the four-dimensional torus with topological charge 1/2. The expansion is performed around the constant field strength abelian solutions found by ’t Hooft. Next to leading order calculations are compared with numerical results obtained with lattice gauge theory techn...

Recently, there has been suggestions that the apparent accelerated expansion of the universe is due not to a cosmological constant, but rather to inhomogeneities in the distribution of matter. In this work, we investigate a specific class of inhomogeneous models that can be solved analytically, namely the dust-dominated Lemâitre-Tolman-Bondi universe models. We show that they do not permit acce...
