Of 490 colonies screened, eight nirK-containing isolates were phylogenetically identified (16S rRNA genes) as members of the Rhizobiales. A nirK gene related to a large cluster

Based on this convergence result, a method for determining the radius of analyticity of solutions of the generalized KdV equation is derived.. Results from the new method and a

if a heavy workload is making health workers reduce the quality of the services, we ought to observe a negative relationship between exogenous shifts in demand (caseload) and the

In this paper, we study the pa- rameterized complexity of local search for the Minimum Fill-in problem in the following form: Given a triangulation H of a graph G, is there a

We show that for several classes of sparse graphs, including planar graphs, graphs of bounded vertex degree and graphs excluding some fixed graph as a minor, an improved solution in

For this, it is necessary to go through the entire characterization of H -minor-free graphs given by Robertson and Seymour in their Graph Minors project (in particular, in [37])

We find that most observed patient and GP characteristics are significantly associated with the length of sick leave (LSL) and medical diagnosis is an important observed factor

the structure of several parameters in sparse graph classes such as planar graphs [1,3,5,14,19,34,37,42,44] bounded genus graphs [20,36], graphs excluding some single-crossing graph
