    Trabajo de investigaciónLa competitividad de las organizaciones está cimentada en la innovación y en el desarrollo tecnológico para la generación y provisión de bienes y servicios que satisfagan las necesidades de las personas y las comunidades. Los procesos de innovación y desarrollo requieren la identificación de necesidades y oportunidades y su observación y documentación detalladas, como punto de partida para el diseño e implementación de soluciones. El fundamento, entonces, del desarrollo de soluciones a las necesidades de los grupos humanos, es el planteamiento de los problemas que se pretende resolver. El planteamiento de problemas exige la observación rigurosa de los procesos asociados al problema, el establecimiento de correlaciones entre los factores o variables que intervienen en el problema, la identificación de los impactos del problema, la especificación de los beneficios que se pueden derivar de su solución y las posibilidades de resolverlo. Muchos problemas se pueden resolver con los aportes de los sistemas de información. Describir problemas objeto de soluciones informáticas requiere una visión sistémica del problema y el desarrollo de actividades básicas de observación de procesos, abstracción del problema, búsqueda de información referida al problema en distintas fuentes documentales (libros, enciclopedias, Internet, especialistas, entre otros), elaboración de descripciones del problema, formulación de preguntas que deberían resolverse sobre el problema, análisis de las posibilidades de resolverlo y la documentación y socialización de los resultados del planteamiento elaborado (informes, gráficas, esquemas, videos, presentaciones).EspecializaciónEspecialista en Seguridad de Rede

    Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

    A measurement of the cosmic-ray spectrum for energies exceeding 4×10184{\times}10^{18} eV is presented, which is based on the analysis of showers with zenith angles greater than 6060^{\circ} detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above 5.3×10185.3{\times}10^{18} eV, the "ankle", the flux can be described by a power law EγE^{-\gamma} with index γ=2.70±0.02(stat)±0.1(sys)\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)} followed by a smooth suppression region. For the energy (EsE_\text{s}) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find Es=(5.12±0.25(stat)1.2+1.0(sys))×1019E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19} eV.Comment: Replaced with published version.

    <p>Abstract</p> <p>Background</p> <p>Although beneficial to health, dietary phytonutrients are bitter, acid and/or astringent in taste and therefore reduce consumer choice and acceptance during food selection. <it>Momordica charantia</it>, commonly known as bitter melon has been traditionally used in Ayurvedic and Chinese medicine to treat diabetes and its complications. The aim of this study was to develop bitter melon-containing recipes and test their palatability and acceptability in healthy individuals for future clinical studies.</p> <p>Methods</p> <p>A cross-sectional sensory evaluation of bitter melon-containing ethnic recipes was conducted among 50 healthy individuals. The primary endpoints assessed in this analysis were current consumption information and future intentions to consume bitter melon, before and after provision of attribute- and health-specific information. A convenience sample of 50, self-reported non-diabetic adults were recruited from the University of Hawaii. Sensory evaluations were compared using two-way ANOVA, while differences in stage of change (SOC) before and after receiving health information were analyzed by Chi-square (χ<sup>2</sup>) analyses.</p> <p>Results</p> <p>Our studies indicate that tomato-based recipes were acceptable to most of the participants and readily acceptable, as compared with recipes containing spices such as curry powder. Health information did not have a significant effect on willingness to consume bitter melon, but positively affected the classification of SOC.</p> <p>Conclusions</p> <p>This study suggests that incorporating bitter foods in commonly consumed food dishes can mask bitter taste of bitter melon. Furthermore, providing positive health information can elicit a change in the intent to consume bitter melon-containing dishes despite mixed palatability results.</p

    HAE international home therapy consensus document

    Hereditary angioedema (C1 inhibitor deficiency, HAE) is associated with intermittent swellings which are disabling and may be fatal. Effective treatments are available and these are most useful when given early in the course of the swelling. The requirement to attend a medical facility for parenteral treatment results in delays. Home therapy offers the possibility of earlier treatment and better symptom control, enabling patients to live more healthy, productive lives. This paper examines the evidence for patient-controlled home treatment of acute attacks ('self or assisted administration') and suggests a framework for patients and physicians interested in participating in home or self-administration programmes. It represents the opinion of the authors who have a wide range of expert experience in the management of HAE

    The objective of this work was to determine the apparent digestibility of nutrients and energy of diets for pirarucu (Arapaima gigas) juveniles. Eight experimental diets containing four energy:protein ratios (11, 10.1, 9, 8 kcal digestible energy per gram of crude protein) and two non-protein energy sources (soybean oil and poultry fat) were tested in a 4x2 factorial scheme, in triplicates. Two hundred and forty pirarucu juveniles weighting 96.8±2.3 g were distributed in 24 cylindrical-conical fiberglass tanks, adapted for feces collection (modified Guelph system). Fish were fed twice a day to apparent satiation, with experimental diets containing 0.5% of chromium oxide as inert marker in order to determine the apparent digestibility coefficients. Diets containing an energy:protein ratio of 9 kcal digestible energy per gram of crude protein resulted in significantly lower apparent digestibility coefficient for dry matter, crude protein and non-nitrogenous extract. The highest apparent digestibility coefficients for crude fat was obtained with soybean oil. The dietary energy:protein ratio influences the nutrient and energy apparent digestibility coefficients to pirarucu juveniles

    En la presente edición, la número 39 de la Revista Temas Socio-Jurídicos, colocamos a disposición de nuestros lectores los ensayos elaborados por los profesores y estudiantes de la Facultad de Derecho de la Universidad Autónoma de Bucaramanga, durante el segundo semestre del presente año 2000. La crisis institucional de la nación inquieta de especial manera a la comunidad académica que se expresa en propuestas, análisis o a veces con simples manifestaciones de perplejidad, que son las que se postulan por los distintos voceros de esta, nuestra escuela jurídica, que este medio escrito las acoge, recopila y divulga para incentivar el debate. Reiteramos la convocatoria a los profesores, estudiantes y egresados a vincularse con sus escritos al desarrollo y proyección de este instrumento de comunicación entre la academia y la comunidad, que sin reticencias ni reparos censurantes deja al criterio del lector el lacerante estímulo de la crítica, en procura de generar a través de la controversia dialéctica un ámbito propicio para el desarrollo intelectual de quienes despliegan el placer de escribir.In this edition, number 39 of the Socio-Legal Issues Magazine, we place at the disposal of our readers the essays prepared by the professors and students of the Faculty of Law of the Autonomous University of Bucaramanga, during the second semester of the current year 2000 The institutional crisis of the nation is particularly worrying way to the academic community that expresses itself in proposals, analyzes or sometimes with simple expressions of perplexity, which are the ones that are postulated by the different spokesmen of this, our legal school, that this written medium welcomes, compiles and disseminates to encourage the debate. We reiterate the call to professors, students and graduates to link with their writings to the development and projection of this instrument of communication between the academy and the community, which without reluctance or censorious objections leaves to the reader's discretion the lacerating stimulus of criticism, in seeks to generate through dialectical controversy a favorable environment for the intellectual development of those who display the pleasure of writing

    Consensus guidelines for the use and interpretation of angiogenesis assays

    Get PDF
    The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference
