We show that the maximum degree of a graph G is equal to theminimum number of ocm sets covering G, where an ocm set is the vertex-disjoint union of elementary odd cycles and onematching, and a collection of ocm sets covers G if every edge is in the matching of an ocm set or in some odd cycle of at least two ocm sets. © 2013 Elsevier B.V.

The oxidative coupling of methane was investigated over alumina supported La2O3/CeO2 catalysts under microwave dielectric heating conditions at different oxygen concentrations. It was observed that, at a given temperature using microwave heating, selectivities for both ethane and ethylene were notably higher when oxygen was absent than that in oxygen/methane mixtures. The differences were attri...
Introduction Uveal melanoma (UM) is the most common primary intraocular malignancy with very poor prognosis. Conventional chemotherapy only rarely prolongs the survival, therefore patients require novel treatment modalities. The discovery of specific receptors for hypothalamic hormones on cancer cells has led to the development of radiolabeled and cytotoxic hormone analogs. Materials and meth...
Abstract Catalytic membrane reactors have the potential to render process of oxidative coupling methane economically viable. Here, results from operando XRD-CT studies three different catalytic reactors, employing BaCo0.4Fe0.4Zr0.2O3-? (BCFZ) and La0.6Sr0.4Co0.2Fe0.8O3-? (LSCF) perovskite membranes with Mn-Na-W/SiO2 La-promoted catalysts, are presented. It is shown that synchrotron X-ray tomogr...
