Implementacion de un establecimiento de larga estadia para el adulto mayor en la ciudad de Talca.

127 p.En este trabajo se realiza un estudio para la Implementación de un Establecimiento de Larga Estadía para el Adulto Mayor en la Ciudad de Talca, enfocado especialmente a los segmentos socioeconómicos ABC1 C2. Se lleva a cabo este proyecto porque en el actual escenario no existe un establecimiento que proporcione este tipo de servicio con una alta calidad, existen clientes por abastecer los cuales están en aumento por la transición demográfica que vive el país. Para lograr conocer el atractivo del mercado se utilizan dos herramientas en particular, el Análisis Porter de las fuerzas competitivas del que se genera una estrategia a nivel de negocio, y el Análisis Situacional FODA del que se genera una matriz con el fin crear estrategias para aprovechar las fortalezas internas, las oportunidades externas, disminuir las debilidades y enfrentar las amenazas. Una vez definido el atractivo del mercado se procede a realizar un análisis económico-financiero para evaluar si es factible llevar a cabo el proyecto y como reacciona al disminuir las principales variables de las que depende el ingreso del establecimiento. Una vez llevado a cabo el estudio se logra concluir que el proyecto es factible puesto que presenta un VAN positivo y además una TIR muy por sobre el costo de oportunidad utilizado para la evaluación del proyecto

Estimate of social and environmental costs for the urban distribution of goods: practical case for the city of Barcelona

The objective of the formulation is to allow to evaluate easily the costs of the urban distribution of goods by means of wheeled vehicles, and to formalize a methodological outline for the mentioned evaluation, which allows its updating and amplification when it was necessary. The sensitivity of the model illustrates the behaviour of the social costs in front of variations of the parameters which intervene in the model. The social costs which are analyzed in this article are the costs of the polluting emissions of the commercial vehicles, the costs of the noise emitted by the same ones, the costs which generate these vehicles in congestion and the costs of the accidents associated to their circulation. The costs of polluting emissions are considered with a matrix model based on an updating of the deliverable 22 of the project MEET. The costs of the noise are associated to the cost of using asphalt noise reducer in the streets with a high daily average intensity. The congestion costs are evaluated starting from the losses of time of the drivers of the commercial vehicles in Barcelona. The costs of accidents are quantified starting from the accident rate studies and mobility in the city of Barcelona.Peer ReviewedPostprint (author's final draft

Ianus: an Adpative FPGA Computer

Dedicated machines designed for specific computational algorithms can outperform conventional computers by several orders of magnitude. In this note we describe {\it Ianus}, a new generation FPGA based machine and its basic features: hardware integration and wide reprogrammability. Our goal is to build a machine that can fully exploit the performance potential of new generation FPGA devices. We also plan a software platform which simplifies its programming, in order to extend its intended range of application to a wide class of interesting and computationally demanding problems. The decision to develop a dedicated processor is a complex one, involving careful assessment of its performance lead, during its expected lifetime, over traditional computers, taking into account their performance increase, as predicted by Moore's law. We discuss this point in detail

Short-term oral administration of non-porous and mesoporous silica did not induce local or systemic toxicity in mice

In this study, two sets of methyl-coated non-porous and mesoporous amorphous silica materials of two target sizes (100 and 300 nm; 10–844 m2/g) were used to investigate the potential role of specific surface area (SSA) and porosity on the oral toxicity in mice. Female Swiss mice were administered by oral gavage for 5 consecutive days. Two silica dose levels (100 and 1000 mg/kg b.w.) were tested for all four materials. All dispersions were characterized by transmission electron microscopy (TEM) and Nanoparticle tracking analysis (NTA). Batch dispersions of porous silica were rather unstable due to agglomeration. Animals were sacrificed one day after the last administration or after a three-week recovery period. No relevant toxicological effects were induced by any of the silica materials tested, as evaluated by body weight, gross pathology, relative organ weights (liver, spleen, kidneys), hematology, blood biochemistry, genotoxicity (Comet assay in jejunum cells and micronucleus test in peripheral blood erythrocytes), liver and small intestine histopathology, and intestinal inflammation. The presence of silica particles in the intestine was evaluated by a hyperspectral imaging microscopy system (CytoViva) using histological samples of jejunum tissue. Silica spectral signatures were found in jejunum samples with all the treatments, but only statistically significant in one of the treatment groups

Guía clínica de atención a menores transexuales, transgéneros y de género diverso

Transgénero; Terapia hormonal cruzada; Identidad de géneroTransgender; Hormone cross therapy; Gender identityTransgènere; Teràpia hormonal creuada; Identitat de gènereSome people, including minors, have a gender identity that does not correspond to the sex assigned at birth. They are known as trans* people, which is an umbrella term that encompasses transgender, transsexual, and other identities not conforming to the assigned gender. Healthcare units for trans* minors require multidisciplinary working, undertaken by personnel expert in gender identity, enabling, when requested, interventions for the minor and their social–familial environment, in an individualized and flexible way during the gender affirmation path. This service model also includes hormonal treatments tailored as much as possible to the individual's needs, beyond the dichotomic goals of a traditional binary model. This guide addresses the general aspects of professional care of trans* minors and presents the current evidence-based protocol of hormonal treatments for trans* and non-binary adolescents. In addition, it details key aspects related to expected body changes and their possible side effects, as well as prior counselling about fertility preservation.Algunas personas, también las menores de edad, tienen una identidad de género que no se corresponde con el sexo asignado al nacer. Se les conoce como personas trans*, que es el término paraguas que engloba transgénero, transexual y otras identidades no conformes con el género asignado. Las unidades de asistencia sanitaria a menores trans* requieren un trabajo multidisciplinario, realizado por personal experto en identidad de género, que permita, cuando así lo soliciten, intervenciones para el menor y su entorno sociofamiliar, de forma individualizada y flexible durante el camino de afirmación de género. Este modelo de servicio también incluye tratamientos hormonales adaptados en la medida de lo posible a las necesidades del individuo, más allá de los objetivos dicotómicos de un modelo binario tradicional. Esta guía aborda los aspectos generales de la atención profesional de menores trans* y presenta el protocolo actual basado en evidencia de tratamientos hormonales para adolescentes trans* y no binarios. Además, detalla aspectos clave relacionados con los cambios corporales esperados y sus posibles efectos secundarios, así como el asesoramiento previo sobre preservación de la fertilidad

Limits on Associated Production of Visibly and Invisibly Decaying Higgs Bosons from Z Decays

Many extensions of the standard electroweak model Higgs sector suggest that the main Higgs decay channel is "invisible", for example, $h \to J J$ where $J$ denotes the majoron, a weakly interacting pseudoscalar Goldstone boson associated to the spontaneous violation of lepton number. In many of these models the Higgs boson may also be produced in association to a massive pseudoscalar boson (HA), in addition to the standard Bjorken mechanism (HZ). We describe a general strategy to determine limits from LEP data on the masses and couplings of such Higgs bosons, using the existing data on acoplanar dijet events as well as data on four and six $b$ jet event topologies. For the sake of illustration, we present constraints that can be obtained for the ALEPH data.Comment: FTUV/94-36, IFIC/94-31 TIFR/TH/94--25, 12 pages + 4 figures (included as ps files at the end

Modified iterative versus Laplacian Landau gauge in compact U(1) theory

Compact U(1) theory in 4 dimensions is used to compare the modified iterative and the Laplacian fixing to lattice Landau gauge in a controlled setting, since in the Coulomb phase the lattice theory must reproduce the perturbative prediction. It turns out that on either side of the phase transition clear differences show up and in the Coulomb phase the ability to remove double Dirac sheets proves vital on a small lattice.Comment: 14 pages, 8 figures containing 23 graphs, v2: 2 figures removed, 2 references adde

Searching for Invisibly Decaying Higgs Bosons at LEP II

We study the potential of LEP II to unravel the existence of invisibly decaying Higgs bosons, predicted in a wide class of models. We perform a model independent analysis, focusing our attention to the final state topologies exhibiting $b \bar{b}$ or $\ell^+ \ell^-$ ($\ell=\mu$ or $e$) pairs and missing energy. We carefully evaluate the signals and backgrounds, choosing appropriate cuts to enhance the discovery limits. Our results demonstrate that LEP II is capable of discovering such a Higgs boson for a wide range of masses and couplings.Comment: 22 pages, latex, uses epsfig.sty, 5 figure

Spontaneous R-Parity violation bounds

We investigate bounds from tree-level and one-loop processes in generic supersymmetric models with spontaneous R-parity breaking in the superpotential. We analyse the bounds from a general point of view. The bounds are applicable both for all models with spontaneous R-parity violation and for explicit bilinear R-parity violation based on general lepton-chargino and neutrino-neutralino mixings. We find constraints from semileptonic B, D and K decays, leptonic decays of the mu and tau, electric dipole moments, as well as bounds for the anomalous magnetic moment of the muon.Comment: 22 page
