Long live the street! Vincent Pinzon
No full textEste trabalho trata-se da urbanização do assentamento Terramar no bairro Vicente Pinzon, na cidade de Fortaleza. O lugar foi selecionado para ser trabalhado, devido suas características físicas e ambientais, bem como a familiaridade com o espaço. Para a melhor compreensão da problemática sobre os assentamentos, buscou-se suas definições e características. O objetivo da proposta foi qualificar os espaços livres públicos, em especial as ruas, ou seja, espaços residuais (não edificados), promovendo aos usuários uma melhor experiência. Adotando infraestrutura verde, para melhoria da drenagem, reformulando o desenho das vias, resultando em espaços de lazer e convivência. Vale ressaltar que se compreende as outras diversas problemáticas existentes em um assentamento, todavia, o projeto volta-se para infraestrutura os espaços livres públicos, como forma de possibilitar aos residentes acesso aos serviços básicos e garantir seu direito de viver a cidade, com equidade.This work deals with the urbanization of the Terramar settlement in the Vicente Pinzon neighborhood, in the city of Fortaleza. The place was selected to be worked on, due to its physical and environmental characteristics, as well as the familiarity with the space. For a better understanding of the issue of settlements, their definitions and characteristics were sought. The objective of the proposal was to qualify public open spaces, especially streets, that is, residual spaces (not built), promoting users a better experience. Adopting green infrastructure to improve drainage, reformulating the design of the roads, resulting in spaces for leisure and coexistence. It is noteworthy that the other various problems existing in a settlement are understood, however, the project turns to infrastructure, public open spaces, as a way to provide residents with access to basic services and guarantee their right to live in the city, with equity
Spatial analysis model as a tool for the integral management of Acacia decurrens in the Tominé reservoir
No full textilustraciones, fotografías a color, mapasResulta de especial importancia optimizar el manejo integral de la colonización de A. decurrens en el Área Operativa Inundable (AOI) del embalse de Tominé, ya que el conocimiento amplio de la ecología y dinámica de la invasión de esta especie, permite determinar con claridad los factores que inciden en su expansión, los cuales, a su vez determinan la distribución espacial del evento y proporcionan la capacidad de modelar el fenómeno natural con el fin de simularlo. Dada esta necesidad de conocimiento, se plantea el objetivo de disponer con un algoritmo en Model Builder - ArcGIS que permita definir las áreas que requieran intervención prioritaria de manejo integral de A. decurrens dentro del AOI del embalse de Tominé, de acuerdo con el tiempo teórico de madurez sexual de la especie después de las intervenciones aleatorias realizadas por el Plan de Manejo Ambiental entre los años 2015 a 2022. (Texto tomado de la fuente)It is especially important to optimize the integral management of the colonization of A. decurrens in the Floodable Operational Area (AOI) of the Tominé reservoir, since the extensive knowledge of the ecology and dynamics of the invasion of this species, allows to clearly determine the factors that affect its expansion, which, in turn, determine the spatial distribution of the event and provide the ability to model the natural phenomenon. in order to simulate it. Given this need for knowledge, the objective is to have an algorithm in Model Builder - ArcGIS that allows defining the areas that require priority intervention for the comprehensive management of A. decurrens within the AOI of the Tominé reservoir, according to the theoretical time of sexual maturity of the species after the random interventions carried out by the Environmental Management Plan between the years 2015 and 2022.EspecializaciónEspecialista en Análisis Espacia

Gravity Measurements in Panama with the IMGC-02 Transportable Absolute Gravimeter
No full textThe work hereafter described was designed to determine the gravity datum at the Centro Nacional de Metrologìa de Panamà CENAMEP AIP through absolute measurement of the gravity acceleration, and settle a gravity network in Panama. Twelve gravity station points were settled. Gravity data were collected with the transportable absolute ballistic gravimeter IMGC-02, operated by a team of the Istituto Nazionale di Ricerca Metrologica INRIM, in cooperation with the CENAMEP AIP and the Instituto Geográfico Nacional “Tommy Guardia” IGNTG. Establishment of the gravity net in Panama, with the highest accuracy currently obtainable, will help in the realization of primary standards and in the definition of the geodetic reference level. Moreover the gravity net may serve as reference for further detailed surveys and detection of long-term, time-dependent gravity variations
Bioethical tensions and feelings in the decision making of adequacy of therapeutic effort by surrogate resulting in a do-not-resuscitate order for hospitalized patients
No full textEste es un estudio original en el que se desarrolló una investigación cualitativa de diseño etnográfico que explora las tensiones bioéticas y los sentimientos en los sustitutos que toman la decisión de adecuación del esfuerzo terapéutico que lleva a la directriz de no reanimación para pacientes hospitalizados, utilizando como herramientas de investigación grupos focales, entrevistas a profundidad, observación participante y revisión documental. Se analizaron los conflictos bioéticos y los sentimientos en un grupo de participantes (familiares, médicos y enfermeras) que han actuado como sustitutos en este tipo de decisiones, y los hallazgos se analizaron a la luz de la ética convergente de Ricardo Maliandi (con énfasis en el conflicto logos-pathos), la perspectiva psicológica de Antonio Damásio y la teoría psicoanalítica clásica de Freud. Los resultados demuestran la presencia de importantes conflictos bioéticos y emocionales en los sustitutos, así como el uso de mecanismos de defensa psicológicos individuales, al momento de afrontar este tipo de decisiones.Doctor en BioéticaDoctoradoThis is an original study in which a qualitative ethnographic design research was developed, which explores bioethical tensions and feelings in surrogates who make the decision to adequate the therapeutic effort that leads to the order of non-resuscitation for hospitalized patients, using as research tools focus groups, in-depth interviews, participant observation and documentary review. Bioethical conflicts and feelings were analyzed in a group of participants (family members, doctors, and nurses) who have acted as surrogates in this type of decision, and the findings were analyzed in the light of Ricardo Maliandi's convergent ethics (with emphasis on the logos-pathos conflict), Antonio Damásio's psychological perspective, and Freud's classical psychoanalytic theory. Results demonstrate the presence of important bioethical and emotional conflicts in surrogates, as well as the use of individual psychological defense mechanisms, when facing this type of decision
Systematic Review and Clinical Insights: The Role of the Ketogenic Diet in Managing Glioblastoma in Cancer Neuroscience
No full textRecent scientific research has shown that the ketogenic diet may have potential benefits in a variety of medical fields, which has led to the diet receiving a substantial amount of attention. Clinical and experimental research on brain tumors has shown that the ketogenic diet has a satisfactory safety profile. This safety profile has been established in a variety of applications, including the management of obesity and the treatment of drug-resistant epileptic cases. However, in human studies, the impact of ketogenic therapy on the growth of tumors and the life expectancy of patients has not provided results that are well characterized. Consequently, our purpose is to improve the comprehension of these features by succinctly presenting the developments and conclusions that have been gained from the most recent study that pertains to this non-pharmacological technique. According to the findings of our study, patients with brain tumors who stick to a ketogenic diet are more likely to experience improved survival rates. However, it is required to conduct additional research on humans in order to more accurately define the anti-tumor efficiency of this diet as well as the underlying processes that support the therapeutic effects of this dieting regimen

Disponible en: https://atlasaves.seo.org/ave/pinzon-azul-de-gran-canaria/La distribución natural e histórica del pinzón azul de Gran Canaria queda restringida a los pinares de la Reserva Natural Integral de Inagua, Ojeda y Pajonales, en la isla de Gran Canaria. En 2008 se constató su reproducción en los pinares de La Cumbre, en el centro de la isla, comenzándose en 2010 un programa de traslocación en esta zona con individuos, mayoritariamente juveniles, procedentes de la cría en cautividad y de la población salvaje de Inagua (194 ejemplares liberados de 2010 a 2019; Delgado y Carrascal, 2021). Nunca se ha constatado su reproducción o presencia en los extensos pinares de Tauro y Pilancones del centro de la isla (Martín y Lorenzo, 2001; Rodriguez y Moreno, 2008), lo cual se puede explicar teniendo en cuenta las preferencias ecológicas del pinzón azul relacionadas con la altitud, precipitación y coberturaaltura del pinar (Carrascal et al., 2017), y la selección de los lugares de nidificación (Rodríguez y Moreno, 2008). Tampoco son adecuados en la actualidad los pinares de Moriscos y Gáldar (Carrascal et al., 2016). La superficie de pinares adecuada para la reproducción del pinzón azul se estima en unos 8 km2 en la Reserva Natural Integral de Inagua-Ojeda-Pajonales, 4 km2 en el entorno de Tamadaba (Carrascal et al., 2017), y unos 2 km2 en La Cumbre (Carrascal et al., 2016).Peer reviewe
Topology-Independent Robust Stability Conditions for Uncertain MIMO Networks
No full textWe give a sufficient and a necessary condition for the topology-independent robust stability of networked systems formed by uncertain MIMO systems. Both conditions involve constants associated with the nominal node dynamics and arc interconnection matrices, the uncertainty bounds, and the maximum connectivity degree of the network; they are scalable (they can be checked locally), independent of the network topology and even of the number of nodes and arcs, and hold for networks of heterogeneous MIMO systems and interconnection matrices, with heterogeneous uncertainties. The dual cases of 1-norm and ∞-norm bounds are considered. In both cases, if the systems at the nodes are diagonal, we get a necessary and sufficient condition. We apply our results to the topology-independent robust stability analysis of a case-study from cancer biology.Accepted Author ManuscriptTeam Tamas Keviczk
Optimal duration and planning of switching treatments taking drug toxicity into account: a convex optimisation approach
No full textWe consider a multi-compartment evolutionary model representing growth, mutation and migration of cancer cells, as well as the effect of drugs, and we design optimal switching targeted cancer therapies where a single drug, or suitable drug combination, is given at each time so as to minimise not only the overall tumor size over a finite horizon, but also drug-provoked side effects. The strong diagonally- dominant structure of the model allows to solve the problem via convex optimisation. We provide an algorithm that yields optimality throughout the whole treatment duration by solving the convex optimisation problem with different horizons, and show how dwell time can be enforced via heuristics. Also the optimal treatment duration can be computed via convex optimisation. The proposed approaches are applied to a model of ALK-rearranged lung carcinoma.Accepted Author ManuscriptTeam Tamas Keviczk
