Optimización del nivel de sostenibilidad de un edificio residencial multifamiliar mediante la metodología SBToolPT-H
Dissertação de mestrado integrado em Engenharia CivilLa sostenibilidad en la construcción y operación de edificaciones tiene como objetivo la
reducción de los impactos ambientales y la utilización de recursos, así como la maximización
de la utilidad y el retorno de inversión en el sector de la construcción. El propósito de este
informe es optimizar el nivel de sostenibilidad de un edificio residencial multifamiliar en
Portugal a través de la metodología SBToolPT-H. Esta metodología, es el resultado del trabajo
desarrollado en la Universidad de Minho y el iiSBE Portugal, y su propósito fue desarrollar una
metodología genérica para evaluar la sostenibilidad de un edificio nuevo, existente o renovado
en zonas urbanas en Portugal, teniendo en cuenta las tres dimensiones de la sostenibilidad:
ambiental, social y económica. Así mismo, esta metodología evalúa 25 parámetros asociados a
los factores más relevantes que pueden afectar el medio ambiente y la salud humana, y esá
dividida en las siguientes nueve categorías: C1 - Cambio climático y calidad del aire interior;
C2 - Uso del suelo y biodiversidad; C3 – Eficiencia energética; C4 – Materiales y gestión de
residuos; C5 – Eficiencia del agua; C6 – Confort y salud de los ocupantes; C7 – Accesibilidad;
C8 – Educación y sensibilidad de la sostenibilidad; y C9 – Costos del ciclo de vida. El puntaje
final de la sostenibilidad depende de la comparación del caso de estudio con la mejor práctica
y la práctica convencional en cada uno de los parámetros evaluados. Adicionalmente, esta
metodología, está dividida en cuatro fases que son la cuantificación del desempeño del edificio
a nivel de cada indicador, la normalización de los parámetros, la agregación de los parámetros
y el cálculo del puntaje final de sostenibilidad. Este trabajo presenta la evaluación y la
optimización de la sostenibilidad de un edificio mediante la metodología SBToolPT-H,
implementando mejoras en los parámetros más relevantes en el desempeño del edificio en
estudio, que, como resultado, fueron los parámetros relacionados con el agua, la energía y los
costos. Finalmente, en la fase de optimización se incorporaron paneles solares fotovoltaicos y
un sistema SAAP, que consiguieron que el edificio pasara de un nivel de sostenibilidad de 0.28
a 0.48, y a nivel cualitativo subiera de una clase C a una clase B.Sustainability in building construction and operation aims at minimization of environmental
impacts and resources utilization as well as maximization of utility and investment returns in
the building sector. The purpose of this paper is to optimize the level of sustainability of a
Multi-Dwelling building in Portugal through the SBToolPT-H methodology. The SBToolPT-H
methodology is the result of the work developed in the University of Minho and the iiSBE
Portugal, and its purpose was to develop a generic methodology to assess the sustainability of
new, existence and renovated buildings in urban areas in Portugal, taking into account three
dimensions: environmental, social, and economic. Furthermore, this methodology assesses 25
parameters associated with the most important factors that may affect the natural environment
or human health and they are divided in nine sustainability categories: C1 – Climate change
and outdoor air quality; C2 – Land use and biodiversity; C3 – Energy Efficiency; C4 – Materials
and waste management; C5 – Water efficiency; C6 – Occupant’s health and comfort; C7 –
Accessibilities; C8 – Education and awareness of sustainability; and C9 – Life-cycle costs. The
final score of sustainability depends on the comparison of the case study with the best practice
and the conventional practice in each one of the parameters that are assessed. In addition, this
methodology is divided into four steps that are the quantification of performance of the building
at the level of each indicator, the normalization of parameters, the aggregation of parameters
and the sustainable score calculation and global assessment. This paper presents the assessment
and optimization of the sustainability of a building using the SBToolPT-H methodology,
implementing improvements alternatives in the most relevant aspects of the case building’s
performance, and, as a result, were the parameters related to water resource, energy and costs.
Finally, in the improvement phase, were incorporated photovoltaic panels and a SAAP system,
that achieved increase the sustainable score of 0.28 to 0.48, and in a qualitative scale increase
of Class C to Class B. (Balaban O, 2016); (Ricardo Mateus, 2011)

A global experiment on motivating social distancing during the COVID-19 pandemic
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
Risk factors associated with Trypanosoma cruziexposure in domestic dogs from a rural community in Panama
Chagas disease, caused by Trypanosoma cruzi infection, is a zoonosis of humans, wild and domestic mammals,including dogs. In Panama, the main T. cruzi vector is Rhodnius pallescens, a triatomine bug whose main naturalhabitat is the royal palm, Attalea butyracea. In this paper, we present results from three T. cruzi serological tests(immunochromatographic dipstick, indirect immunofluorescence and ELISA) performed in 51 dogs from 24 housesin Trinidad de Las Minas, western Panama. We found that nine dogs were seropositive (17.6% prevalence). Dogswere 1.6 times more likely to become T. cruzi seropositive with each year of age and 11.6 times if royal palms wherepresent in the peridomiciliary area of the dog’s household or its two nearest neighbours. Mouse-baited-adhesivetraps were employed to evaluate 12 peridomestic royal palms. All palms were found infested with R. pallescens withan average of 25.50 triatomines captured per palm. Of 35 adult bugs analysed, 88.6% showed protozoa flagellates intheir intestinal contents. In addition, dogs were five times more likely to be infected by the presence of an additionaldomestic animal species in the dog’s peridomiciliary environment. Our results suggest that interventions focused onroyal palms might reduce the exposure to T. cruzi infection
A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Effect of Alginate from Chilean Lessonia nigrescens and MWCNTs on CaCO3 crystallization by classical and non classical methods
In our crystallization experiments, the influence of alginate from Chilean Lessonia nigrescens and functionalized multi-walled carbon nanotubes (MWCNTs) was tested through electrocrystallization (EC) and gas diffusion (GD) methods on the crystal growth of calcium carbonate (CaCO3) and their possible stabilization of proto-structures in amorphous CaCO3 (ACC) state through pre-nucleation clusters (PNC) essays with automatic potentiometric titrations were performed. CaCO3 crystals obtained in the in vitro above-mentioned crystallization systems were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectrometry (EDS) and powder X-ray diffractometer (XRD). Our experimental findings showed that ALG and functionalized MWCNTs stabilized truncated and agglomerated vaterite-like particles through GD and EC methods. While, on the other hand, we obtained qualitative information about induction or inhibition of CaCO3 nucleation that was provided by potentiometric titrations.FONDECYT

Tuberculosis: integrated studies for a complex disease 2050
Tuberculosis (TB) has been a disease for centuries with various challenges [1]. Like
other places where challenges and opportunities come together, TB challenges were
the inspiration for the scientific community to mobilize different groups for the
purpose of interest. For example, with the emergence of drug resistance, there has
been a huge volume of research on the discovery of new medicines and drug
delivery methods and the repurposing of old drugs [2, 3]. Moreover, to enhance the
capacity to detect TB cases, studies have sought diagnostics and biomarkers, with
much hope recently expressed in the direction of point-of-care tests [4].
Despite all such efforts as being highlighted in 50 Chapters of this volume, we
are still writing about TB and thinking about how to fight this old disease–implying
that the problem of TB might be complex, so calling the need for an integrated
science to deal with multiple dimensions in a simultaneous and effective manner.
We are not the first one; there have been proposed integrated platform for TB
research, integrated prevention services, integrated models for drug screening,
integrated imaging protocol, integrated understanding of the disease pathogenesis,
integrated control models, integrated mapping of the genome of the pathogen, etc.
[5–12], to name some.
These integrated jobs date back decades ago. So, a question arises: why is there a
disease named TB yet? It might be due to the fact that this integration has happened
to a scale that is not global, and so TB remains to be a problem, especially in
resource-limited settings.
Hope Tuberculosis: Integrated Studies for a Complex Disease helps to globalize

Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at √sNN=2.76 TeV
The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at sNN=2.76 TeV. The J/ψ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 μb−1. The cross section for coherent J/ψ production in the rapidity interval −3.6<y<−2.6 is measured to be dσJ/ψcoh/dy=1.00±0.18(stat)−0.26+0.24(syst) mb. The result is compared to theoretical models for coherent J/ψ production and found to be in good agreement with those models which include nuclear gluon shadowing
