A DEA-inspired approach to selecting parking areas for dangerous-goods trucks

The transport of dangerous goods by trucks requires special conditions for rest areas. By considering the set of existing service areas, the present work develops a procedure for selecting the subgroup of the most suitable service areas for modification in order to provide a service to dangerous-goods transporters. Under multiple criteria, a new DEA-inspired model is developed that uses the main characteristics of the problem under study with the goal of selecting the best locations. Through the application of this model to Spanish territory with the help of Geographical Information Systems, various solutions are suggested. The final decision on the number of areas to be located depends on corresponding authorities, whose main priority is to satisfy economic criteria

Self-Assembled Monolayers on C(0001)

This chapter describes the application of tunneling and AFM to the study of inorganic and organic adsorbates on C(0001) at the submonolayer and ML level. The C(0001) surface can be taken as a model system for the study of adsorption processes because it is atomically smooth and exhibits a low chemical reactivity, allowing an easy handling in the atmosphere. The knowledge of adsorption on carbon is important in the field of electrocatalysis because carbon is widely used as a matrix for the dispersion of catalytically active metallic clusters.Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicada

Adaptación a los nuevos Grados de las metodologías docentes empleadas en una asignatura de Estadística Económico-Empresarial

Durante el presente curso 2009/2010 la Universidad Pablo de Olavide (UPO), de Sevilla, ha puesto en marcha el nuevo mapa de titulaciones adaptado al Espacio Europeo de Educación Superior (EEES), el cual está compuesto por 16 grados y 6 dobles grados. Hasta llegar a este punto la UPO trabajó duro durante más de 6 años en la adaptación de su docencia al nuevo marco establecido por dicho EEES. Con tal objetivo, se puso en marcha en la Facultad de Empresariales, entre otras, una Experiencia Piloto de implantación del sistema de créditos europeos pretendiendo, fundamentalmente, renovar la metodología docente, incrementar la calidad de la docencia y de hacerla más cercana al alumno, siempre atendiendo a los planes de estudio actualmente vigentes. En el presente trabajo mostramos la adaptación que se realizó en la asignatura de Estadística e Introducción a la Econometría de la extinta Licenciatura en Administración y Dirección de Empresas en el marco de la Experiencia Piloto y los cambios que se acometieron posteriormente para su implantación en el nuevo Grado en Administración y Dirección de Empresas bajo el nombre: Estadística Empresarial I. Haremos hincapié en aquellos aspectos más destacados relativos al nuevo sistema de evaluación basado en evaluación continua.Artículo revisado por pare

Isolation of Corynebacterium falsenii and description of Corynebacterium aquilae sp. nov., from eagles

Biochemical, molecular chemical and molecular genetic studies were performed on seven unidentified Gram-positive, rod-shaped organisms recovered from eagles. The strains were provisionally identified as Corynebacterium jeikeium with the commercial API Coryne system, but they were able to grow under anaerobic conditions and were non-lipophilic. Comparative 16S rRNA gene sequencing studies demonstrated that the isolates belonged phylogenetically to the genus Corynebacterium. Three strains were identified genotypically as Corynebacterium falsenii; the remaining four strains corresponded to a hitherto unknown lineage within the genus Corynebacterium, associated with a small subcluster of species that included Corynebacterium diphtheriae and its close relatives. The unknown bacterial strains were readily distinguished from these and other species of the genus by biochemical tests. Based on both phenotypic and phylogenetic evidence, it is proposed that the unknown bacterial strains from eagles should be classified as Corynebacterium aquilae sp. nov. (type strain is S-613(T)=CECT 5993(T)=CCUG 46511(T))
