Ground- and excited-state properties of M-center oxygen vacancy aggregates in the bulk and the surface of MgO

Aggregates of oxygen vacancies (F centers) represent a particular form of point defects in ionic crystals. In this study we have considered the combination of two oxygen vacancies, the M center, in the bulk and on the surface of MgO by means of cluster model calculations. Both neutral and charged forms of the defect M and M+ have been taken into account. The ground state of the M center is characterized by the presence of two doubly occupied impurity levels in the gap of the material; in M+ centers the highest level is singly occupied. For the ground-state properties we used a gradient corrected density functional theory approach. The dipole-allowed singlet-to-singlet and doublet-to-doublet electronic transitions have been determined by means of explicitly correlated multireference second-order perturbation theory calculations. These have been compared with optical transitions determined with the time-dependent density functional theory formalism. The results show that bulk M and M+ centers give rise to intense absorptions at about 4.4 and 4.0 eV, respectively. Another less intense transition at 1.3 eV has also been found for the M+ center. On the surface the transitions occur at 1.6 eV (M+) and 2 eV (M). The results are compared with recently reported electron energy loss spectroscopy spectra on MgO thin films.

On the generalized obnoxious center problem: antimedian subsets

The set of vertices that maximize (minimize) the remoteness is the antimedian (median) set of the profile. It is proved that for an arbitrary graph G and S V (G) it can be decided in polynomial time whether S is the antimedian set of some profile. Graphs in which every antimedian set is connected are also considered.

On The Center Sets and Center Numbers of Some Graph Classes

For a set S of vertices and the vertex v in a connected graph G, max x2S d(x, v) is called the S-eccentricity of v in G. The set of vertices with minimum S-eccentricity is called the S-center of G. Any set A of vertices of G such that A is an S-center for some set S of vertices of G is called a center set. We identify the center sets of certain classes of graphs namely, Block graphs, Km,n, Kn −e, wheel graphs, odd cycles and symmetric even graphs and enumerate them for many of these graph classes. We also introduce the concept of center number which is defined as the number of distinct center sets of a graph and determine the center number of some graph classes

Photoperiod-dependent plasticity of circadian pacemaker center in the brain of the Madeira cockroach Rhyparobia maderae

To various degrees, insects in nature adapt to and live with two fundamental environmental rhythms around them: (1) the daily rhythm of light and dark, and (2) the yearly seasonal rhythm of the changing photoperiod (length of light per day). It is hypothesized that two biological clocks evolved in organisms on earth which allow them to harmonize successfully with the two environmental rhythms: (1) the circadian clock, which orchestrates circadian rhythms in physiology and behavior, and (2) the photoperiodic clock, which allows for physiological adaptations to changes in photoperiod during the course of the year (insect photoperiodism). The circadian rhythm is endogenous and continues in constant conditions, while photoperiodism requires specific light inputs of a minimal duration. Output pathways from both clocks control neurosecretory cells which regulate growth and reproduction. This dissertation focuses on the question whether different photoperiods change the network and physiology of the circadian clock of an originally equatorial cockroach species. It is assumed that photoperiod-dependent plasticity of the cockroach circadian clock allows for adaptations in physiology and behavior without the need for a separate photoperiodic clock circuit. The Madeira cockroach Rhyparobia maderae is a well established circadian clock model system. Lesion and transplantation studies identified the accessory medulla (aMe), a small neuropil with about 250 neurons, as the cockroach circadian pacemaker. Among them, the pigment-dispersing factor immunoreactive (PDF-ir) neurons anterior to the aMe (aPDFMes) play a key role as inputs to and outputs of the circadian clock system. The aim of my doctoral thesis was to examine whether and how different photoperiods modify the circadian clock system. With immunocytochemical studies, three-dimensional (3D) reconstruction, standardization and Ca2+-imaging technique, my studies revealed that raising cockroaches in different photoperiods changed the neuronal network of the circadian clock (Wei and Stengl, 2011). In addition, different photoperiods affected the physiology of single, isolated circadian pacemaker neurons. This thesis provides new evidence for the involvement of the circadian clock in insect photoperiodism. The data suggest that the circadian pacemaker system of the Madeira cockroach has the plasticity and potential to allow for physiological adaptations to different photoperiods. Therefore, it may express also properties of a photoperiodic clock.

Prevalencia y factores asociados de síntomas osteomusculares en miembro superior y cuello en los trabajadores de un call center

Objetivo: determinar la prevalencia en los últimos 6 meses de los síntomas de cuello y miembro superior además de sus factores asociados, en trabajadores de una entidad financiera call center en el periodo comprendido de abril a octubre del año 2009. Métodos: se realizó un análisis descriptivo trasversal, a través de la aplicación de un cuestionario de morbilidad sentida que abarcó aspectos demográficos, antecedentes personales y antecedentes laborales. La presencia de los síntomas se documentó en una tabla donde se confrontaron los síntomas osteomusculares y los segmentos afectados en los últimos 6 meses. Adicionalmente se les pidió a los sujetos identificar la postura más frecuente durante su trabajo mediante un diagrama. Resultados: los síntomas más prevalentes fueron dolor en la muñeca derecha (0,44; IC 95% 0,37 – 0,51), dolor en el cuello (0,43; IC95% 0,36 – 0,50), rigidez en el cuello (0,33; IC95% 0,26 – 0,40) y dolor en la mano derecha (0,36; IC95% 0,29 – 0,43). Se encontraron diferencias estadísticamente significativas en cuanto al género en la presencia de dolor en muñeca derecha (26,1% hombres contra 73,9% mujeres; p=0,005), dolor en mano derecha (25% hombres versus 75% mujeres; p=0,008), síntomas neurológicos en mano derecha (19,4% versus 80,6%; p=0,001) y dolor en hombro derecho (26,3% hombres versus 73,7% mujeres; p=0,048). También se evidencio una diferencia estadísticamente significativa en la prevalencia del síntoma dolor en muñeca derecha según el auto reporte de mayor exigencia en el desempeño (85,2% con la percepción de mayor exigencias, versus 14,8% en los sujetos que no; p=0,020). Además una diferencia estadísticamente significativa con mayor presencia de síntomas en muñecas y manos en sujetos con postura en dorsiflexión de de las mismas (muñeca derecha 72,8%, p=0,001; muñeca izquierda 43,5%, p=0,020; mano derecha 62%, p=0,003). Conclusión: después de realizar el estudio se encontró como principal síntoma el dolor, localizado en: la muñeca derecha, el cuello, la mano derecha y el hombro derecho, con diferencias mayores para el género femenino según la postura de las muñecas, lo que es compatible con las condiciones de trabajo y la respuesta fisiológica a estas condiciones.

Análisis estructural de la visión estratégica futura internacional de la organización para alcanzar objetivos diferenciales enfocados en contact center: MAPFRE, ANDIASISTENCIA

Por medio del estudio realizado a los diferentes enfoques y estudios hechos hacia el área de recursos humanos y cultura (organizacional y nacional) se han logrado identificar ciertos procesos y características que pueden ser implementados en el modelo de integración de operaciones de Call Center de Mapfre. Partiendo de la cultura organizacional pasando por la cultura nacional y sabiendo como ingresar y ser aceptado en una cultura internacional. Características y procesos totalmente opuestos desde su implementación pasando por sus costos y su posterior gestión; debido al choque cultural y la forma de gestión planteada por la organización basado en su modelo estructural de jerarquización y centralización de toma de decisiones. Queriendo lograr con éste trabajo generar un proyecto de unificación de un sector operativo dirigido hacia servicio al cliente y de la misma manera servir como un ejemplo a demás organizaciones nacionales o multinacionales con el objetivo de aumentar la eficiencia de su administración y la eficiencia de su estructura de costos siempre enfocado a un bien último que es el servicio al cliente.
