Los tiempos modernos conllevan una reinvención constante en todos los campos actuales. Sectores como la restauración colectiva hospitalaria también requieren de nuevas técnicas y procedimientos que les permitan satisfacer las necesidades actuales. La complicada situación económica existente en la actualidad se ve reflejada en sectores tan básicos como el hospitalario. De manera que toda la posible optimización de gastos se antoja imprescindible. Todos estos factores han llevado al Sector Hospitalario de Huesca a replantearse la situación actual de sus cocinas; buscando ser más eficientes y novedosas, tratando de conseguir optimizar la economía de las cocinas sin disminuir un ápice la calidad y el servicio ofrecido a los paciente

Mejora de la aplicación clínica de métodos e instrumentación para evaluación de trastornos del equilibrio: Monitorización de pacientes y apoyo al diagnóstico por medio de modelos predictivos

Entre las patologías más frecuentes en la actualidad, destacan los trastornos del equilibrio, teniendo especial prevalencia en personas mayores y en países desarrollados. Los trastornos del equilibrio son una patología que se caracteriza principalmente por síntomas de vértigo y mareo, y se calcula que un cuarto de la población tendrá un episodio vertiginoso en su vida. Las caídas y las lesiones inducidas por las mismas son problemas de salud pública de primer orden a nivel mundial. De manera complementaria, también existen alteraciones o patologías que pueden afectar a los sistemas sensoriales que sustentan el equilibrio, existiendo la necesidad de monitorizarlos para evaluar su progresión en el tiempo. Sin embargo, no resulta sencillo obtener información objetiva del diagnóstico o progresión de un paciente afectado por trastornos del equilibrio; destacando la complejidad para obtener informes concisos con información comprensible y fácil de interpretar por facultativos sanitarios, que deben prescribir tratamientos a dichos pacientes.Asimismo, y en relación con la necesidad de obtener métodos o procesos para poder aprovechar mejor la información en el campo de la salud, destaca el incremento exponencial de los datos que los centrossanitarios generan y requieren manejar, así como la compleja gestión de dicha información, siendo la disciplina científica Machine Learning una posible solución para abordar esta problemática. Sin embargo, aplicar las técnicas de este tipo de disciplina en el campo de la salud conlleva un alto grado de complejidad.La presente tesis pretende dar respuesta a las incertidumbres y problemáticas expuestas a través de variasinvestigaciones que han tratado de proporcionar información objetiva sobre el estado de pacientes que presentan trastornos del equilibrio, así como monitorizar este tipo de patologías mediante diversos métodos e instrumentación; igualmente, se han definido los procesos y particularidades para la generación de modelos predictivos como herramienta de apoyo al diagnóstico en el ámbito de la salud. En concreto, los objetivos de la tesis son: generar y proporcionar información objetiva sobre el estado de pacientes que presentan trastornos del equilibrio; monitorizar y analizar la progresión de este tipo de patologías en pacientes inmersos en tratamientos de rehabilitación; generar modelos predictivos para mejora del diagnóstico en el ámbito de la salud.Esta tesis se ha complementado con una estancia de investigación de cuatro meses en el Laboratoire de biomécanique et mécanique des chocs (Université Gustave Eiffel) en Lyon (Francia). El cuerpo principal de esta tesis consiste en una compilación de cinco artículos, los cuales han sido publicados en revistas científicas indexadas en el JCR.<br /

MCQ-Balance: a method to monitor patients with balance disorders and improve clinical interpretation of posturography

Background An estimated 20% to 30% of the global population has suffered a vertiginous episode. Among them, 20% do not receive a clear diagnosis. Improved methods, indicators and metrics are necessary to assess the sensory systems related to balance, especially when patients are undergoing treatment for vertiginous episodes. Patients with balance disorders should be monitored for changes at the individual level to gather objective information. In this study, we evaluate the use of the MCQ-Balance (Measure, Classify and Qualify) assessment for examining a patient’s balance progression using tests to measure static balance control and dynamic postural balance with a stabilometric platform. Materials and Methods The MCQ-Balance assessment comprises three stages: (i) measuring the progression of each variable between two separate and consecutive days (called sessions) using the Magnitude-Based Decision analysis; (ii) classifying the progression of the patient’s balance with a score; and (iii) qualifying the progression of the patient’s balance from the resulting scores using a set of rules. This method was applied to 42 patients with balance disorders of peripheral or central origin characterised by vertigo as the cardinal symptom. Balance progression was measured using the MCQ-Balance assessment over the course of three months, and these results were compared with the assessment of a clinical expert. Results The MCQ-Balance assessment showed an accuracy of 83.4% and a Cohen’s Kappa coefficient of 0.752 compared to the assessment of a clinical expert. Conclusion The MCQ-Balance assessment facilitates the monitoring of patient balance and provides objective information that has the potential to improve medical decision making and the adjustment of individual treatment

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8 TeV

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel

Transverse-momentum and pseudorapidity distributions of charged hadrons in pppp collisions at s\sqrt{s} = 7 TeV

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at $\sqrt{s} = 7$~TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit-pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity \dnchdeta|_{|\eta| < 0.5} = 5.78\pm 0.01\stat\pm 0.23\syst for non-single-diffractive events, higher than predicted by commonly used models. The relative increase in charged-particle multiplicity from $\sqrt{s} = 0.9$ to 7~TeV is 66.1\%\pm 1.0\%\stat\pm 4.2\%\syst. The mean transverse momentum is measured to be 0.545\pm 0.005\stat\pm 0.015\syst\GeVc. The results are compared with similar measurements at lower energies.Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at sqrt(s) = 7 TeV are measured with the inner tracking system of the CMS detector at the LHC.

Measurement of the charge ratio of atmospheric muons with the CMS detector

We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC. Muons were detected in the momentum range from 5 GeV/ c to 1 TeV/ c . The surface flux ratio is measured to be 1.2766±0.0032(stat.)±0.0032(syst.) , independent of the muon momentum, below 100 GeV/ c . This is the most precise measurement to date. At higher momenta the data are consistent with an increase of the charge ratio, in agreement with cosmic ray shower models and compatible with previous measurements by deep-underground experiments.We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC.

Combined search for the quarks of a sequential fourth generation

Results are presented from a search for a fourth generation of quarks produced singly or in pairs in a data set corresponding to an integrated luminosity of 5 inverse femtobarns recorded by the CMS experiment at the LHC in 2011. A novel strategy has been developed for a combined search for quarks of the up and down type in decay channels with at least one isolated muon or electron. Limits on the mass of the fourth-generation quarks and the relevant Cabibbo-Kobayashi-Maskawa matrix elements are derived in the context of a simple extension of the standard model with a sequential fourth generation of fermions. The existence of mass-degenerate fourth-generation quarks with masses below 685 GeV is excluded at 95% confidence level for minimal off-diagonal mixing between the third- and the fourth-generation quarks. With a mass difference of 25 GeV between the quark masses, the obtained limit on the masses of the fourth-generation quarks shifts by about +/- 20 GeV. These results significantly reduce the allowed parameter space for a fourth generation of fermions
