LA NECESIDAD DE LA RESPONSABILIDAD SOLIDARIA DEL PATRON CON EL DEPOSITARIO EN LAS DILIGENCIAS DE EMBARGO EN EL DERECHO LABORAL

A través de la historia la clase obrera ha mostrado ser una de las más débiles frete al más fuerte económicamente que es el patrón y México no es la excepción, al ser el trabajador objeto de abusos por parte del patrón, es por ello que se busca la protección a los derechos laborales de la clase trabajadora, derechos que han surgido con el paso del tiempo hasta llegar a ser plasmados en el artículo 123 de la Constitución Política de México, misma que da origen a la Ley Federal del Trabajo. Actualmente donde acude el trabajador para hacer uso de sus derechos laborales y como puede hacer uso de sus derechos laborales el trabajador. Acude a las Juntas de Conciliación y Arbitraje poniéndolas en movimiento al convertirse en un accionante de sus derechos laborales al seguir un procedimiento laboral. Es por ello que en la presente investigación va encaminada al estudio de la responsabilidad solidaria que debe existir entre el patrón y el depositario, que se presenta durante un proceso laboral y así proponer soluciones a efecto de darle prontitud y celeridad a los juicios laborales

The detached dust shells of AQ And, U Ant, and TT Cyg

Detached circumstellar dust shells are detected around three carbon variables using Herschel-PACS. Two of them are already known on the basis of their thermal CO emission and two are visible as extensions in IRAS imaging data. By model fits to the new data sets, physical sizes, expansion timescales, dust temperatures, and more are deduced. A comparison with existing molecular CO material shows a high degree of correlation for TT Cyg and U Ant but a few distinct differences with other observables are also found.Comment: Letter accepted for publication on the A&A Herschel Special Issu

The Stellar Populations of Starburst Galaxies Through near infrared spectroscopy

We study the central (inner few hundred parsecs) stellar populations of four starburst galaxies (NGC34, NGC1614, NGC3310 and NGC7714) in the near-infrared (NIR), from 0.8 to 2.4microns, by fitting combinations of stellar population models of various ages and metallicities. The NIR spectra of these galaxies feature many absorption lines. For the first time, we fit simultaneously as much as 15 absorption features in the NIR. The observed spectra are best explained by stellar populations containing a sizable amount (20 to 56 % by mass) of ~1Gyr old stellar population with Thermally Pulsing-Asymptotic Giant Branch stars. We found that the metallicity of the stars which dominates the light is solar. Metallicities substantially different from solar give a worse fit. Though the ages and metallicities we estimate using the NIR spectroscopy are in agreement with values from the literature based on the UV/optical, we find older ages and a larger age spread. This may be due to the fact that the optical is mostly sensitive to the last episode of star formation, while the NIR better maintains the record of previous stellar generations. Another interesting result is that the reddening estimated from the whole NIR spectrum is considerably lower than that based on emission lines. Finally, we find a good agreement of the free emission line spectrum with photoionization models, using as input spectral energy distribution the synthetic composite template we derived as best-fit.Comment: 11 pages, 7 figures, accepted for publication on MNRA

Organisation-based co-ordination of wireless sensor networks

Esta tesis presenta el Coalition Oriented Sensing Algorithm (COSA) como un mecanismo de auto-organización para redes de sensores inalámbricos (WSN). El objetivo del algoritmo es extender la vida útil de la red, al mismo tiempo que la funcionalidad básica de la misma - la monitorización fiel del entorno- también es garantizada. La evaluación del funcionamiento del algoritmo se apoya en una plataforma de simulación novedosa, RepastSNS. La implementación de COSA y la preparación de la plataforma para el desarrollo de los experimentos dan lugar a una estructura software reutilizable. Esta estructura favorece la implementación de futuras ampliaciones del algoritmo, así como su exportación a otros entornos. El uso de las WSNs se ha popularizado en los últimos años. Sus particulares características han favorecido la aplicación de las mismas a múltiples áreas. No obstante, la gestión energética de las WSNs sigue siendo objeto de estudio para los investigadores, que tratan de aliviar las fuertes restricciones que estas presentan en cuanto a disponibilidad de energía se refiere. En esta línea, se han propuesto diversas técnicas para conservación de la energía. La restricción energética es especialmente acusada cuando las WSNs se despliegan en entornos que no permiten la conexión de los nodos a la red ni la recarga de sus baterías. Este es el tipo de entorno considerado para la evaluación de COSA. El caso de uso estudiado considera una WSN desplegada a lo largo de un río navegable con el objetivo de monitorizar el estado del agua y detectar la presencia de polución en ella. La definición de COSA se inspira en el paradigma de los Sistemas Multiagente (MAS) mediante la identificación de los nodos de la WSN con agentes del MAS. COSA define un algoritmo para formación de coaliciones basado en diálogos por parejas de agentes (nodos). El algoritmo está completamente embebido en el comportamiento del agente. Los agentes que implementan COSA se comunican con sus vecinos para intercambiar información sobre su percepción del entorno y su estado. Como resultado de esta comunicación local, los agentes eligen su rol en la organización y establecen relaciones leader-follower. La definición de este tipo de relaciones se basa en dos funciones relacionales y un protocolo de negociación que establece las normas de coordinación. Los agentes se juntan en grupos para compensar la calidad de los datos recogidos y el consumo de energía asociado. Esta habilidad permite adaptar el consumo energético de la red a cambios en el entorno, al mismo tiempo que se satisfacen los objetivos de muestreo en cuanto a calidad de la información enviada al sink se refiere. Los resultados experimentales obtenidos apoyan las hipótesis preliminares en cuanto al comportamiento de COSA. A partir de estos resultados también se pone de manifiesto la relación existente entre la coordinación local y las ganancias obtenidas por el uso de COSA.This thesis introduces the Coalition Oriented Sensing Algorithm (COSA) as a self-organisation mechanism for Wireless Sensor Networks (WSNs). This algorithm aims at extending the network lifetime at the same time that the primary goal of the network -faithfully monitoring the environment- is also guaranteed. The evaluation of the algorithm performance is based on a novel simulator, RepastSNS. The implementation of COSA and the development of its experimental setup define a reusable software structure to work over this simulation environment. It also favours the performance of future enhancements of the algorithm as well as its exportation. The use of WSNs has become widespread in the last years. The special characteristics of these networks have favoured their application to many different areas. One of the major concerns about WSNs refers to their energy management, as they are typically constraint in energy availability. This problem has gained the attention of researchers that try to improve this aspect of the WSNs by defining network energy conservation strategies. This constraint becomes especially acute when the network deployment environment does not allow for battery replenishment or node connection to the net. This is the case of the environment considered for COSA evaluation. The use case considered is a WSN deployed along a waterway in order to monitor the state of the water and detect the presence of pollutant sources. The definition of COSA is inspired by the Multiagent Systems (MAS) paradigm through the identification of nodes in a WSN with agents in a MAS. COSA defines a coalition formation algorithm based on peer-to-peer dialogues between neighbouring agents (nodes). The algorithm is completely embedded into the agent behaviour. Agents implementing COSA communicate with its neighbours to exchange information about their perception of the environment and their state. As a result of this local communication, agents select the role to play in the organisation and can then establish leader-follower relationships. The establishment of these peer-to-peer relationships is based on two relational functions and a negotiation protocol that lays down the norms of this co-ordination. Agents join in groups in order to trade off the accuracy of the sensed data and their energy consumption. As a consequence, COSA endows the network with self-organisation capacity. This ability is used to adapt energy consumption to changes in the environment and, at the same time, to fulfil sampling objectives in terms of the quality of the information reported to the sink. The results derived from experimentation support preliminary hypotheses about COSA good performance. They also provide insights on the relationship between local co-ordination and the gains obtained from COSA's use

Design of the β3-adrenergic agonist treatment in chronic pulmonary hypertension secondary to heart failure trial

Combined pre-and post-capillary hypertension (CpcPH) is a relatively common complication of heart failure (HF) associated with a poor prognosis. Currently, there is no specific therapy approved for this entity. Recently, treatment with beta-3 adrenergic receptor (β3AR) agonists was able to improve pulmonary hemodynamics and right ventricular (RV) performance in a translational, large animal model of chronic PH. The authors present the design of a phase II randomized clinical trial that tests the benefits of mirabegron (a clinically available β3AR agonist) in patients with CpcPH due to HF. The effect of β3AR treatment will be evaluated on pulmonary hemodynamics, as well as clinical, biochemical, and advanced cardiac imaging parameters.

Three centuries of Greek culture under the Roman empire: Homo Romanus Graeca Oratione

The underlying theme of Three Centuries of Greek Culture under the Roman Empire is the idea that, under Roman rule, Greek culture was still alive and dynamic and continued to exert a degree of cultural domination, either real or apparent. So, we hope to analyse the meanings of concepts such as “Greek” or “Greece” in the Empire. Are we right to assume that there was a clear opposition between Greek and Roman? Or would it be more accurate to speak of a “Graeco-Roman world”? It would certainly be possible to make a list of “elements of identity”, on both sides —Greek and Roman—, but, in this case, where should the borders between identity and community be placed? Three Centuries of Greek Culture under the Roman Empire presents several approaches to the period between the second and fourth centuries AD from a variety of angles, perspectives and disciplines. Until now, this time has usually been considered to be the junction of the decline between the classical world and the emergence of the medieval world; however, this book establishes a basis for considering the Imperial period as a specific stage in cultural, historical and social development with a distinct personality of its own
