Relação entre limitações físicas e sintomatologia depressiva em idosos europeus
Objetive: To explore the relationship between physical limitations and depressive symptomatology.
Methods: Study with a cross-sectional design. Data were from the population-based Survey of Health, Aging, and Retirement in Europe (SHARE) wave seven (2017). Physical limitations were assessed by the Global Activity Limitations Indicator (GALI). The EURO-D scale was used to measure depressive symptomatology.
Results: The sample consisted of 13450 individuals with a mean age of 70.7 ± 7.6 years. Physical limitations showed a positive and significant correlation with depressive symptomatology (r=0.221; p < 0.001). For men, having physical limitations increased 46% (OR=1.46, 95% IC: 1.35, 1.57) the probability of having depressive symptoms and for women increased 50% (OR=1.50, 95% IC: 1.38, 1.63).
Conclusion: Having physical limitations increases the likelihood of having depressive symptomatology.Objetivo: Explorar a relação entre as limitações físicas e a sintomatologia depressiva.

QoS metrics-in-the-loop for endowing runtime self-adaptation to robotic software architectures
The design of a robot that is capable of operating autonomously in
a changing and unstructured scenario is based on complex software architec-
tures, in which perceptual and actuation components, as well as deliberative
ones, are considered. The inherent dynamism of this kind of scenarios forces
the software architecture to be able to adapt the robot’s behaviour to de-
tected changes at runtime. This adaptation is often hard-coded by the robotic
engineer within software components, thus considering the specific situations
that s/he believes to be appropriate at design-time. Subsequently, when any
of these situations occur, software components can react by updating parame-
ters, planning decisions, etc., then ensuring that the robot provides the desired
response. On the contrary, adding and managing situations that were not ini-
tially considered is a cumbersome and expensive task. This paper describes
a complete model-based framework for endowing a robot control architecture
with the ability of self-adapting the robot’s behaviour at runtime. On the one
hand, this framework provides robotic designers with a textual model editor
allowing them to specify variation points in the robot behaviour and define
how these variation points should be configured at runtime according to the
perceived situation. On the other hand, the framework also includes a code
generator that, taking the previous models as an input, generates and ap-
propriately configures the runtime infrastructure needed to monitor relevant
non-functional properties and, according to their evolution, perform the ap-
propriate behaviour adaptations to meet the required robot quality-of-service
(QoS). The proposed framework is discussed and validated in two case studies
using different and well-known robotics software architectures. The first use
case runs over a simulation environment generated using Webots. In a second
use case a real robot is moved in an intralogistic scenari
Técnicas de geoprocessamento para delimitação de sistemas físico-naturais e ações de planejamento: o caso do município de Ipu - CE
O trabalho foi desenvolvido como forma de subsidiar ações de planejamento e gestão ambiental no município de Ipu-Ce, a partir de uma metodologia geoecológica fundamentada na análise integrada da relação natureza-sociedade a partir de uma caracterização socioeconômica e natural. Foram elaborados mapas através do uso de geotecnologias de informações geográficas, de forma a delimitar os sistemas físico-naturais, possibilitando a caracterização e discussão do mesmo. Percebe-se, em Rodriguez (1994), que os sistemas formadores da paisagem são complexos e exigem uma multiplicidade de classificações que podem, segundo o autor, enquadrar-se perfeitamente em três princípios básicos de análise: o genético, o estrutural sistêmico e o histórico, que se fundem numa classificação complexa. Conhecer esses sistemas físico-naturais e sua relação com a sociedade é importante para tomadas de decisões territoriais, pautadas na capacidade de suporte dos mesmos com relação à atividade antrópica
Low-diffusion Xe-He gas mixtures for rare-event detection: electroluminescence yield
[EN] High pressure xenon Time Projection Chambers (TPC) based on secondary scintillation (electroluminescence) signal amplification are being proposed for rare event detection such as directional dark matter, double electron capture and double beta decay detection. The discrimination of the rare event through the topological signature of primary ionisation trails is a major asset for this type of TPC when compared to single liquid or double-phase TPCs, limited mainly by the high electron diffusion in pure xenon. Helium admixtures with xenon can be an attractive solution to reduce the electron diffu- sion significantly, improving the discrimination efficiency of these optical TPCs. We have measured the electroluminescence (EL) yield of Xe-He mixtures, in the range of 0 to 30% He and demonstrated the small impact on the EL yield of the addition of helium to pure xenon. For a typical reduced electric field of 2.5 kV/cm/bar in the EL region, the EL yield is lowered by similar to 2%, 3%, 6% and 10% for 10%, 15%, 20% and 30% of helium concentration, respectively. This decrease is less than what has been obtained from the most recent simulation framework in the literature. The impact of the addition of helium on EL statistical fluctuations is negligible, within the experimental uncertainties. The present results are an important benchmark for the simulation tools to be applied to future optical TPCs based on Xe-He mixtures.The NEXT Collaboration acknowledges support from the following agencies and institutions: the European Research Council (ERC) under the Advanced Grant 339787-NEXT; the European Union's Framework Programme for Research and Innovation Horizon 2020 (2014-2020) under the Marie Sklodowska-Curie Grant Agreements No. 674896, 690575 and 740055; the Ministerio de Economa y Competitividad of Spain under grants FIS2014-53371-C04, RTI2018-095979, the Severo Ochoa Program SEV-2014-0398 and the Mara de Maetzu Program MDM-2016-0692; the GVA of Spain under grants PROMETEO/2016/120 and SEJI/2017/011; the Portuguese FCT under project PTDC/FIS-NUC/2525/2014, under project UID/FIS/04559/2013 to fund the activities of LIBPhys, and under grants PD/BD/105921/2014, SFRH/BPD/109180/2015; the U.S. Department of Energy under contracts number DEAC02-06CH11357 (Argonne National Laboratory), DE-AC0207CH11359 (Fermi National Accelerator Laboratory), DE-FG02-13ER42020 (Texas A& M) and DE-SC0019223/DESC0019054 (University of Texas at Arlington); and the University of Texas at Arlington.

Assessment of the Body Composition and the Loss of Fat-Free Mass through Bioelectric Impedance Analysis in Patients Who Underwent Open Gastric Bypass
Background. Bariatric surgery is considered an effective option for the management of morbid obesity. The incidence of obesity has been gradually increasing all over the world reaching epidemic proportions in some regions of the world. Obesity can cause a reduction of up to 22% in the life expectancy of morbidly obese patients. Objective. The objective of this paper is to assess the weight loss associated with the first 6 months after bariatric surgery using bioelectric impedance analysis (BIA) for the evaluation of fat mass and fat-free mass. Method. A total of 36 morbidly obese patients were subjected to open gastric bypass surgery. The patients weight was monitored before and after the procedure using the bioelectric impedance analysis. Results. Bariatric surgery resulted in an average percentage of weight loss of 28.6% (40 kg) as determined 6 months after the procedure was performed. Analysis of the different components of body weight indicated an undesirable loss of fat-free mass along with the reduction of total body weight. Conclusion. Open gastric bypass induced a significant loss of total weight and loss of fat-free mass in patients six months after the surgery. The use of bioelectric impedance analysis resulted in an appropriate estimation of the total weight components in individuals subjected to bariatric surgery allowing a more real analysis of the variation of weight after the surgery
