    Uno de los pilares del crecimiento económico de China es su mercado laboral. Detrás de la segunda economía más grande del mundo, compuesta por una mano de obra de más de 900 millones y basada en una sólida y creciente estabilidad económica, se encuentra una población activa sujeta a condiciones laborales muy diferentes a las de sus competidores occidentales, creando así un ventaja y un alto grado de atractivo para los inversores extranjeros. Este documento explora el mercado laboral y los derechos laborales en China, el papel desempeñado por el gobierno, las organizaciones de trabajadores y los actores internacionales, los flujos migratorios y las perspectivas de un país considerado como la "fábrica del mundo"

    Molecular characterization of Haemophilus parasuis ferric hydroxamate uptake (fhu) genes and constitutive expression of the FhuA receptor

    P. 49-59Bacteria have evolved a set of highly specialized proteins to capture iron in irondepleted environments. The acquisition and uptake of iron present in the extracellular milieu of eukaryotic organisms is indispensable for the growth and survival of microbial pathogens in the course of infection. Haemophilus parasuis is the causative agent of Glässer disease, which is responsible for considerable financial losses in pig-rearing worldwide. To gain insight into the mechanisms involved in siderophore-mediated iron uptake in H. parasuis, genes in the H. parasuis ferric hydroxamate uptake (Fhu) region were amplified in the work being reported here. As has been described in A. pleuropneumoniae, an Fhu genomic region was also present in H. parasuis, being composed of four potential consecutive open reading frames (ORF) designated as fhuC, fhuD, fhuB, and fhuA, respectively. By immunoblotting, using a cross-reactive polyclonal antibody raised against Actinobacillus pleuropneumoniae FhuA protein, it was demonstrated that this protein was constitutively expressed in H. parasuis and its level of expression was not modified under conditions of restricted iron availability. This is the first report describing the presence of the fhu genes in H. parasuis. Our results indicate that FhuA protein expression is not affected under ironrestricted conditions, however, it is one of the targets of the humoral immune responseS

    In the pasteurization process, the microorganisms that are used for the fermentation and rotting of bier are mainly eliminated by high temperatures. This project is about a study of feasibility for the implementation, cost analysis and the rent of the automation for the process of equipment for flash pasteurization in a bier industry. The main point of this job is to obtain the advantages in costs, production and mainly in the quality of the final product of the pasteurization working with an automation process. For this, we have considered a Programmable Logic Controller for the acquisition, treatment and process of the signals generated by the field instruments. The process will be monitored and supervised continuously, so and SCADA system will be developed for this task in an operation room, and for the field will be implemented a Human Machine Interface. It will be considered the different rules and standards that are in force in our country at the moment of the design

    7 p.Haemophilus parasuis is the agent responsible for causing Gla¨ sser’s disease, which is characterized by fibrinous polyserositis, polyarthritis and meningitis in pigs. The purpose of this study was to investigate the in vitro ability of two H. parasuis serovars of different virulence (serovar 5, Nagasaki strain, highly virulent, belonging to serovar 5, and SW114 strain, nonvirulent, belonging to serovar 3) to adhere to and invade porcine kidney epithelial cells (PK-15 line). Nagasaki strain was able to attach at high levels from 60 to 180 min of incubation irrespective of the concentrations compared (107–1010 CFU), and a substantial increase of surface projections could be seen in PK-15 cells by scanning electron microscopy. This virulent strain was also able to invade effectively these epithelial cells, and the highest invasion capacity was reached at 180 min of infection. On the contrary, nonvirulent SW114 strain hardly adhered to PK-15 cells, and it did not invade these cells, thus suggesting that adherence and invasion of porcine kidney epithelial cells could be a virulence mechanism involved in the lesions caused by H. parasuis Nagasaki strain in this organS

    La mejor forma de ayudar a las personas con discapacidad es rompiendo las barreras de cohesión social que limitan sus oportunidades y brindándoles la autonomía suficiente para que puedan valerse por sí mismos; cuando se le enseña a una persona con habilidades físicas y mentales diferentes a ser autónomo, genera confianza en sí mismo y esto puede ayudar eficazmente en el desarrollo evolutivo de su tratamiento de rehabilitación. Pues es aquí en donde la arquitectura juega un rol importante, si brindamos un ambiente dinámico aplicando los modelos de rehabilitación basados en la comunidad y empleando los principios de accesibilidad universal para que las personas con discapacidad ejerciten su rol de autonomía e inclusión social, podremos generar un gran aporte en su proceso de rehabilitación La presente investigación contempla un análisis contextual y diagnóstico de la problemática, los objetivos son la creación de un centro integral de rehabilitación que cubra la demanda existente de personas con discapacidad en Piura La investigación se organiza en capítulos, el primero de ellos es la fundamentación de proyecto el cual describe el marco teórico, metodología implementada, la investigación programática, análisis de la localización y parámetros normativos; el segundo capítulo describe el proyecto arquitectónico en base a los lineamientos planteados previamente para luego concluir con la memoria descriptiva de estructuras, instalaciones eléctricas, sanitarias, mecánicas y plan de seguridad en la edificaciónThe best way to help people with disabilities is by breaking down the barriers of social cohesion that limit their opportunities and giving them sufficient autonomy so that they can fend for themselves; When a person with different physical and mental abilities is taught to be autonomous, it builds selfconfidence and this can effectively help in the evolutionary development of their rehabilitation treatment. Well, this is where architecture plays an important role, if we provide a dynamic environment by applying communitybased rehabilitation models and using the principles of universal accessibility so that people with disabilities exercise their role of autonomy and social inclusion, we can generate a great contribution to your rehabilitation process This research contemplates a contextual analysis and diagnosis of the problem, the objectives are the creation of a comprehensive rehabilitation center that meets the existing demand of people with disabilities in Piura. The research is organized in chapters, the first of which is the project foundation which describes the theoretical framework, implemented methodology, programmatic research, location analysis and normative parameters; The second chapter describes the architectural project based on the guidelines previously proposed and then concludes with the descriptive memory of structures, electrical, sanitary, mechanical installations and safety plan in the buildingTesi
