La perla. Club social, cultural, ocupacional y de emprendimiento: una alternativa para la comunidad LGBT de la zona metropolita de Guadalajara

Este proyecto aborda dos asuntos fundamentales en México: el aumento en la edad y la esperanza de vida y el crecimiento del grupo LGBT (lésbico, gay, bisexual y transexual), que, junto con el envejecimiento poblacional, este nicho también aumenta en edad. Esto representa un problema ya que no hay servicios ni productos para este segmento de la población; no son considerados o pierden su visibilidad social al ser adultos mayores. A partir de esto, se identificó la oportunidad de emprender un club social, cultural y de emprendimiento para el grupo LGBT que busca una inclusión con el resto de la población heterosexual. En el club tendrán varias actividades y formas de planear sus vidas, así como de aprender a sociabilizar con gente común a ellos y sus intereses. Para la creación de esta propuesta se utilizaron herramientas de medición como encuestas cualitativas, cuantitativas, mystery shopper, encuestas y entrevistas a fondo de las que obtuvimos información que validó la oferta de valor

Prolactin responses to stress induced by a competitive swimming effort

Purpose: The aim of the present study was to investigate the changes in prolactin (PRL) plasma concentrations induced by competitive swimming practice. Methods: Twenty-three males, 13 trained swimmers (experimental group) and 10 sedentary and healthy students (age-matched control group) took part in this investigation. The swimmers were assessed at three points: basal conditions, pre- and post-swimming competition (100 m freestyle), whereas subjects from the control group only undertook the basal trial. The variables analysed were: several body composition measures, anxiety level (STAI questionnaire), PRL and lactic acid concentrations. Results: No statistical differences were observed in PRL basal levels between groups. An evident PRL response to pre-competition psychological stress was observed in the experimental group, since the PRL plasma concentration rose from 4.02±0.53 ng/ml (basal conditions) to 5.52±0.53 ng/ml (p≤0.05). The PRL response to the competitive effort produced an important increase in its plasma concentration (10.07±1.59 ng/ml), showed statistical differences from pre-competition (p≤0.01) and from basal conditions (p≤0.001). A significant rise in plasma lactate levels just at the end of the effort was found, although it did not correlate with PRL levels in the same situation. Conclusion: While we observed a remarkable response of PRL to psychological and physiological stress induced by a short term competitive effort in swimming, no changes in PRL basal levels were exhibited with swim training. More research is needed to clarify these findings

Ground characterization of building energy models

The calibration of building energy models is crucial for their use in some applications that depend on their accuracy for adequate performance, such as demand response and model predictive control (MPC). In general, energy models offer many possibilities/strategies when characterizing a construction system, and such a characterization is key when analyzing both its thermal behavior and its energy impact. This research analyzes the different ways to characterize the thermal interaction of the building energy model (BEM) with the ground, comparing conventional approaches with new approaches based on both optimization of the former and dynamic ground characterizations. Using a model adjusted to a real case study, each of the existing options are analyzed, in which a different control of the ground temperature both in terms of its temporal oscillation and its location in the building (based on thermal zones) is taken into account. Exhaustive monitoring of a real building and measuring the ground and ground floor surface temperatures have made establishing which EnergyPlus components/objects best characterize the ground-slab interaction possible, both in terms of the simplicity of modeling and the cost (economic and technical) required for each of them. As will be seen, there are objects with an excellent cost/effectiveness ratio when characterizing the groun

The FRII Broad Line Seyfert 1 Galaxy: PKSJ 1037-2705

In this article, we demonstrate that PKSJ 1037-2705 has a weak accretion flow luminosity, well below the Seyfert1/QSO dividing line, weak broad emission lines (BELs) and moderately powerful FRII extended radio emission. It is one of the few documented examples of a broad-line object in which the time averaged jet kinetic luminosity, $\bar{Q}$, is larger than the total thermal luminosity (IR to X-ray) of the accretion flow, $L_{bol}$. The blazar nucleus dominates the optical and near ultraviolet emission and is a strong source of hard X-rays. The strong blazar emission indicates that the relativistic radio jet is presently active. The implication is that even weakly accreting AGN can create powerful jets. Kinetically dominated ($\bar{Q}>L_{bol}$) broad-line objects provide important constraints on the relationship between the accretion flow and the jet production mechanism.Comment: To appear in ApJ November 1, 2008, v687n1 issu

Isolation and partial characterization of a plasmid in the extremely halophilic archaebacterium Halococcus morrhuae CCM 537

The extremely halophilic archaebacterium Halococcus morrhuae CCM 537 was found to contain’’ a plasmid, pHM2, of 6.0 kb. A restriction map was constructed. Southern hybridization of pHM2 DNA to DNA extracted from other Halococcus sp. strains revealed the presence of a similar plasmid in one other strain. A plasmid of Halobacterium trapanicum shared common sequences with pHM2. Other plasmids from halobacteria displayed no homology with pHM2. The characterization of pHM2 may make it useful for the development of cloning vectors for extremely halophilic archaebacteria

Microwave foaming of sodium silicate-ortodibasic calcium phosphate mixtures

[ES] La acción de la energía de las microondas, genera porosidad interna en un material cerámico húmedo. En el presente trabajo, se analiza el efecto del tiempo de aplicación de las microondas sobre el comportamiento térmico, cambio de volumen, tamaño y distribución de poros, reacciones químicas y disolución de probetas cerámicas de silicato de sodio / ortofosfato cálcico dibásico (FCD). Para caracterizar las espumas cerámicas, se utilizó, análisis de imágenes, microscopía electrónica de barrido, difracción de rayos X y picnometría de helio. Se obtuvieron espumas cerámicas con una porosidad de 71 a 79 % y un rango de tamaño de poro de 10 a 200 μm. Después de 90 segundos, las probetas alcanzaron una temperatura de aproximadamente 130°C y una pérdida de peso de 23% con respecto al peso total de la muestra. Se observaron cambios de volumen y de los compuestos químicos en las muestras espumadas cuando se varió la proporción del FCD en la mezcla. Para contenidos de 10, 20 y 30% en peso de FCD, el incremento de volumen se redujo a 350, 300 y 250% respectivamente. En muestras con 30% de FCD calentadas por microondas durante 90 segundos la cantidad de un nuevo compuesto en la espuma, constituido por β-NaCaPO4, fue del orden de 42.9%. En esa misma muestra, el 57.1 % restante fue FCD. Considerando pruebas de disolución de un gramo de muestra en 100 ml de agua destilada, la disolución obtenida en muestras espumadas por microondas después de 20 días fue de 900 ppm/gr para el Na y de 2.7 ppm/gr para el Ca en muestras con 10% de FCD. En muestras con 30% de FCD la disolución de Na fue de 470 ppm/gr y del Ca de 5 ppm/gr.[EN] The effect of microwave application on the thermal behaviour, volume change, size and pore size distribution as well as chemical reactions and dissolution of sodium silicate/dibasic calcium phosphate ceramic (DCF) samples have been analysed. Ceramics foams with porosities between 71 and 79 wt% and pore sizes ranging from 10 to 200 microns have been obtained. After 90 seconds the temperature of samples reach about 130 °C with a weight loss of 23 wt%. Differences in the proportion of DCF in the initial mixture originate changes in volume and different chemical compounds in the final obtained foams. Additions of 10, 20 and 30 wt% of DCF originates volume increases of 350, 300 and 250 % respectively. In foam samples with 30 wt% of DCF, heated by microwave during 90 sec., the amount of the new compound β-NaCaPO4 was about 42.9 wt%. The other component of this sample, 57.1 wt%, was DCF. Dissolution tests were made, using one gram of sample, in 100 ml of distilled water. The dissolution of 10 wt% DCF foamed samples, after 20 days into water, were 900 ppm/gr of Na and 2.7 ppm/gr of Ca. In samples with 30 wt% of DCF the dissolution were 470 ppm/gr and 5 ppm/gr for Na and Ca respectively.Peer reviewe
