O viveiro botânico da Samaritana como proposta de um uso temporário no contexto de Xabregas
Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Arquitetura apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.A revitalização é actualmente um dos temas centrais no trabalho de
arquitectura e planeamento urbano nas cidades do mundo ocidental.
Servindo-se de uma área específica como objecto de estudo, o trabalho
“Revitalizar em Cenários de Abandono” procura entender os fenómenos
de encolhimento urbano, e fazer uma reflexão crítica sobre diferentes
formas de revitalizar as áreas afectadas.
No município de Lisboa, o período da desindustrialização e dinâmicas
acentuadas de suburbanização deixaram para trás inúmeras áreas
abandonadas, distribuídas segundo um padrão irregular. Partes do
centro histórico e antigas áreas industriais ficaram suspensas durante
décadas. Muitas encontram-se ainda hoje à espera de novos usos; à
espera de uma nova vida.
Este trabalho procura compreender a área de Xabregas, incluída no Vale
de Chelas, em Lisboa, como cenário de abandono. É apresentada uma
revisão bibliográfica sobre o tema do encolhimento urbano, com especial
enfoque nas consequências espaciais e no problema dos vazios urbanos.
Numa aproximação à componente prática, apresentam-se vários tipos de
resposta para o problema dos vazios urbanos.
Por fim, no âmbito do projecto, pretende-se explorar as vantagens dos
usos temporários, como estratégia para uma rápida revitalização de
áreas expectantes. O projecto desenvolvido toma o edifício da antiga
Fábrica de Fiação e Tecidos de Xabregas, abandonado há mais de
sessenta anos, como oportunidade para iniciar uma dinâmica eficaz de
revitalização, tendo como ponto de partida a introdução de um uso
temporário.ABSTRACT: Urban Revitalization is currently one of the most important topics for
architects and urban planners working in western civilization. By focusing
on a specific site, the work “Revitalization in Abandoned Scenarios” tries
to understand urban shrinkage as a complex phenomenon, and brings up
a critical reflection on different ways of revitalizing affected areas.
In the municipality of Lisbon, the deindustrialization period and strong
suburbanization dynamics left behind a number of abandoned areas,
distributed in an irregular pattern. Parts of the historic center and old
industrial areas were kept in standby for decades. Many of those are still
waiting for new uses; for a new life.
This work aims to understand the areas of Xabregas and Chelas Valley, in
Lisbon, as abandoned scenarios. A literature review on urban shrinkage is
presented with a special focus on spatial consequences as the problem of
urban voids. Several solutions for the problem of urban voids are
presented as approaching a practical component in this work.
Finally, in a project mindset, the work intends to take advantage of
temporary uses and meanwhile spaces, as strategies for a fast
revitalization process. The project takes the building of the former Cotton
Spinning Factory of Xabregas, abandoned since more than sixty years, as
an opportunity to start effective revitalization dynamics, initiated by the
introduction of temporary uses.N/
Growth or somatotrophic hormone: new perspectives in isolated GH deficiency after description of the mutation in the GHRH receptor gene in individuals of Itabaianinha county, Brazil
Além de influenciar o crescimento corpóreo, o hormônio do crescimento,
ou somatotrófico, desempenha importante papel no metabolismo,
composição corporal, perfil lipídico, estado cardiovascular e
longevidade. Seu controle é multi-regulado por hormônios, metabólitos
e peptídeos hipotalâmicos. Dados sobre a Deficiência Isolada de GH
(DIGH) obtidos a partir da descrição da mutação IVS1+1G→A no gene
do receptor do hormônio liberador do GH (GHRH-R) em indivíduos da
cidade de Itabaianinha, SE, são revisados. São abordadas novas perspectivas
sobre o modelo de resistência ao GHRH, a importância do
GHRH no controle da secreção de GH, a freqüência das mutações do
gene do GHRH-R, a relevância diagnóstica do IGF-I e os achados
metabólicos, cardiovasculares e de qualidade de vida nestes indivíduos._________________________________________________________________________________________ ABSTRACT: In addition to stimulating body growth, growth or somatotrophic hormone
plays an important role in metabolism, body composition, lipid
profile, cardiovascular status and longevity. Its control is multiregulated
by hormones, metabolites and hypothalamic peptides. Obtained data
of the isolated growth hormone deficiency (IGHD) after the description
of the IVS1+1G→A GHRH receptor gene mutation in individuals of Itabaianinha
County are reviewed. New perspectives about the growth hormone
resistance model, the importance of GHRH in the control of GH
secretion, the frequency of GHRH-R gene mutations, the diagnostic relevance

Mapping density, diversity and species-richness of the Amazon tree flora
Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution
Measurement of the W-boson mass in pp collisions at √s=7 TeV with the ATLAS detector
A measurement of the mass of the W boson is presented based on proton–proton collision data recorded in 2011 at a centre-of-mass energy of 7 TeV with the ATLAS detector at the LHC, and corresponding to 4.6 fb−1 of integrated luminosity. The selected data sample consists of 7.8×106 candidates in the W→μν channel and 5.9×106 candidates in the W→eν channel. The W-boson mass is obtained from template fits to the reconstructed distributions of the charged lepton transverse momentum and of the W boson transverse mass in the electron and muon decay channels, yielding
mW=80370±7 (stat.)±11(exp. syst.)
±14(mod. syst.) MeV
=80370±19MeV,
where the first uncertainty is statistical, the second corresponds to the experimental systematic uncertainty, and the third to the physics-modelling systematic uncertainty. A measurement of the mass difference between the W+ and W−bosons yields mW+−mW−=−29±28 MeV
Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We
estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from
1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories.
Methods We used data from 3663 population-based studies with 222 million participants that measured height and
weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate
trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children
and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the
individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference)
and obesity (BMI >2 SD above the median).
Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in
11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed
changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and
140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of
underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and
countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior
probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse
was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of
thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a
posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%)
with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and
obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for
both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such
as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged
children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls
in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and
42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents,
the increases in double burden were driven by increases in obesity, and decreases in double burden by declining
underweight or thinness.
Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an
increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy
nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of
underweight while curbing and reversing the increase in obesit
Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study
Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
