Elm trees and elm leaf beetles: patterns of herbivory

Arno Sprecher

Over the years numerous branch-and-bound procedures for solving the resource-constrained project scheduling problem (RCPSP) have been developed. Enumerating delaying alternatives, extension alternatives, feasible posets, feasible sequences, feasible completion times or feasible subsets, they all aim at nding as fast as possible a makespan minimal schedule among the resource and precedence feasi...

ELM physics and ELM mitigation in ITER

Edge Localised Modes are characteristic of the high performance, H-mode plasmas that are required for the attainment of Q = 10/500MW fusion power in the first phase of ITER operation. The energy released by a type I ELM, in good confinement plasmas, is typically 510% of the plasma stored energy; with low collisionality plasmas at the upper end of the range. Dimensional analysis, experiment and ...

zinc and manganese nutrition of acacia, elm and plane trees in isfahan landscape through hole mulching

in this study, the effect of hole mulching application of zn and mn on acacia, elm, and plane nutrition was examined in the green spaces of isfahan. three different sites were chosen in a randomized complete block design using six treatments of: 1. cow manure compost, 2. cow manure vermicompost, 3. urban waste compost, 4. urban waste vermicompost, 5. dug hole refilled with the same soil coming ...

In this paper we prove four cases of the vanishing conjecture of differential operators with constant coefficients and also a conjecture on the Laurent polynomials with no holomorphic parts, which were proposed in [Zh3] by the third named author. We also give two examples to show that the generalizations of both the vanishing conjecture and the Duistermaat-van der Kallen theorem [DK] to Laurent...
