ResumenAntecedentesLa NLPC es el procedimiento de referencia para litos renales mayores a 2 cm, desplazando así a la cirugía abierta. Se reporta una incidencia variable en las complicaciones, del 12.5% al 52.5%, siendo las principales fiebre y sangrado.ObjetivoIdentific...

Abstract The irrigated rice–wheat system of north west India is not sustainable, as currently practised, due to over-exploitation of groundwater, soil degradation, labour scarcity, high fuel and labour costs, and air pollution from stubble burning. Labour and water scar...

AbstractGenetically modified (GM) crops may contain newly expressed proteins that are described as “intractable”. Safety assessment of these proteins may require some adaptations to the current assessment procedures. Intractable proteins are defined here as those protei...

Abstract The use of natural antimicrobial compounds, such as cinnamic acid and its phenolic derivatives, may help prevent survival of Escherichia coli O157:H7 and other pathogenic bacteria in foods. The limitation of the widespread use of these acids is their low solubi...

Abstract Given a dense set of points lying on or near an embedded submanifold M 0 ⊂ R n of Euclidean space, the manifold fitting problem is to find an embedding F :M→ R n that approximates M 0 in the sense of least squares. When the dataset is modeled by a probability d...

Marine invertebrate oocytes establish chemoattractant gradients that guide spermatozoa towards their source. In sea urchin spermatozoa, this relocation requires coordinated motility changes initiated by Ca(2+)-driven alterations in sperm flagellar curvature. We discover...

Abstract We present an approach for teaching linear algebra using models. In particular, we are interested in analyzing the modeling process under an APOS perspective. We will present a short illustration of the analysis of an economics problem related to production in ...

AbstractComposition duality principles for the qualitative and finite element analysis of primal and dual evolution mixed variational inclusions in reflexive Banach spaces are presented. A general distributed control diffusion problem illustrates the theory.

We are given a edge-weighted undirected graph G=(V,E) and a set of labels/colors C={1,2,...,p}. A non-empty subset C"v@?C is associated with each vertex v@?V. A coloring of the vertices is feasible if each vertex v is colored with a color of C"v. A coloring uniquely def...

The case of a 20 year old man with severe class III maloclussion due to mandibular prognathism and maxillary retrusion who also presents severe laterognathia with condylar hyperplasia and de- fi cient zygomatic projection with dental crowding caused by a collapsed maxil...
