    Tese de doutoramento em Geografia (especialidade em Estudos da Paisagem)O cinema √© objeto situado em um terreno te√≥rico valioso para a compreens√£o de eventos espaciais e humanos, com isso contribuindo para esclarecer cada vez mais o que costuma ser classificado como o ‚Äúuniverso cotidiano‚ÄĚ. Assim, a vasta oferta tem√°tica que o cinema nos traz e o seu papel na forma√ß√£o cultural dos espa√ßos, t√™m exigido novas formas de an√°lise pelos profissionais envolvidos com as imagens movimento, especialmente em Geografia Cultural. Sob essa √≥tica, o cinema presta-se e oferece se a explora√ß√£o de conex√Ķes te√≥ricas cuja tend√™ncia estabeleceu-se em dire√ß√£o ao entrela√ßamento dos terrenos movedi√ßos das teorias, filosofias e hist√≥ria do cinema e da fotografia, estudos em Cultura Visual, Geografia Cultural, Cartografia e Arquitetura. √Č a Cartografia Cinem√°tica o m√©todo aqui eleito capaz de realizar a transdisciplinaridade entre essas teorias e disciplinas diversas, de forma a explorar tanto a representa√ß√£o dos espa√ßos, como o universo mais-que-representacional dos ecr√£s, e os processos de significa√ß√£o a eles relacionados. Nesse sentido, os filmes s√£o vistos como mapas em movimento, documentos de espa√ßos e espacialidades, mas tamb√©m como registos mnem√īnicos, iconogr√°ficos, topof√≠licos e psicogeogr√°ficos. Esse trabalho, portanto, prop√īs-se a investigar em um caso de estudo, as representa√ß√Ķes da paisagem cultural de Copacabana no cinema. Essas paisagens foram cartografadas em filmes escolhidos, varrendo quase 13 anos de produ√ß√£o brasileira ‚Äď de 1965 a 1978. Os filmes foram confrontados pelos contextos ideol√≥gicos, econ√īmicos, sociais e culturais no qual se inserem, tanto os da cidade do Rio de Janeiro como do Brasil. Para efetivar tal objetivo, a pesquisa esclarece as conex√Ķes entre as artes paisag√≠sticas, cartogr√°ficas, as geografias e o cinema; a fun√ß√£o das paisagens nos filmes e a sua evolu√ß√£o como tecnologia de representa√ß√£o; a evolu√ß√£o das geografias f√≠lmicas at√© as cartografias cinem√°ticas; e vasculha teorias contempor√Ęneas em geografias culturais e suas poss√≠veis conex√Ķes com o cinema, como contributos adicionais para a constru√ß√£o de chaves de leitura de filmes. Estuda igualmente, a configura√ß√£o da paisagem urbana de Copacabana de forma a reunir seus par√Ęmetros hist√≥ricos e culturais caracter√≠sticos, incluindo as in√ļmeras salas de exibi√ß√£o que o bairro abrigou, cujo rebatimento, tanto no desenvolvimento urban√≠stico como nas pr√°ticas socio_culturais relacionadas √© indiscut√≠vel. Observa as opening scenes de outros 5 filmes tendo em vista sua capacidade de transporte, deslocando os espectadores at√© o territ√≥rio f√≠lmico atrav√©s de elementos ic√īnicos da paisagem carioca. E finalmente analisa os filmes, os protagonistas e suas hist√≥rias sob as perspetivas trazidas pelas cartografias cinem√°ticas.Cinema is an object located in a valuable theoretical terrain for the understanding of spatial and human events, thus contributing to clarify more and more what is usually classified as the ‚Äúeveryday universe‚ÄĚ. Thus, the vast thematic offer that cinema brings us and its role in the cultural formation of spaces, has required new forms of analysis by professionals involved with movies, especially in Cultural Geography. From this perspective, cinema lends and offers itself to the exploration of theoretical connections whose tendency has been established towards the intertwining of the slippery terrains of theories, philosophies and history of cinema and photography, studies in Visual Culture, Cultural Geography, Cartography and Architecture. Cinematic Cartography is the method chosen to implement transdisciplinarity between those different ways of thinking, to reach the representation of spaces on screens and the processes of meaning related to them, as exposed in the films. In this sense, films are seen as moving maps, documents of spaces and spatialities, but also as mnemonic, iconographic, topophilic and psychogeographical registers. This work proposes to investigate a case study, the Copacabana cultural landscape representation in the movies, mapping 5 chosen films, sweeping 15 years of Brazilian production - from 1965 to 1978. These films are confronted by ideological, economic, social, and cultural contexts in which they are inserted, in the city of Rio de Janeiro and Brazil. To accomplish this objective, the research clarifies the connections between the landscape arts, cartography, geographies, and cinema; the function of landscapes in films and their evolution as a representational technology in cultural visual history; the evolution of filmic geographies to cinematic cartography; and search contemporary theories in cultural geographies and their possible connections with cinema as additional contributions to the construction for reading films keys. It studies the configuration of the urban landscape of Copacabana to bring together its historical characteristics and cultural parameters, including the countless exhibition halls that the neighbourhood housed, whose impact on related social practices is indisputable. The research also observes the film opening scenes and their ability to transport viewers to the filmic location through iconic elements of Rio's landscape. And finally, it analyses the films, the protagonists and their stories from the perspectives brought by cinematic cartographies

    Introduction: Cleft lip and palate is a congenital malformation resulting from the inadequate fusion of bony structures during embryonic development. The etiology is multifactorial, involving genetic and environmental factors. Methodology: This study constitutes a descriptive epidemiological analysis focusing on the investigation of cases of live births with cleft lip and palate in Brazil. Data collection will be conducted through the Live Birth Information System (SINASC) during the period from 2017 to 2021. Results: The gender distribution of live births with cleft lip and palate indicates a male predominance in the sample, representing approximately 58.49% (n=4,390) of the total. Meanwhile, the percentage of female individuals is approximately 41.01% (n=3,078). The category "Unknown" has a very small representation, accounting for only 0.51% (n=38) of the sample. Conclusion: It is observed that live births with cleft lip and palate should not be overlooked. There is a significant number of cases each year, necessitating further related studies to provide solutions in society that directly benefit those affected.Introdu√ß√£o: A fenda labial e palatina √© uma malforma√ß√£o cong√™nita resultante da n√£o fus√£o das estruturas √≥sseas adequadas durante o desenvolvimento embrion√°rio.

    The Short Strip ASIC (SSA) is one of the four front-end chips designed for the upgrade of the CMS Outer Tracker for the High Luminosity LHC. Together with the Macro-Pixel ASIC (MPA) it will instrument modules containing a strip and a macro-pixel sensor stacked on top of each other. The SSA provides both full readout of the strip hit information when triggered, and, together with the MPA, correlated clusters called stubs from the two sensors for use by the CMS Level-1 (L1) trigger system. Results from the first prototype module consisting of a sensor and two SSA chips are presented. The prototype module has been characterized at the Fermilab Test Beam Facility using a 120 GeV proton beam

    Selection of the silicon sensor thickness for the Phase-2 upgrade of the CMS Outer Tracker

    Get PDF
    During the operation of the CMS experiment at the High-Luminosity LHC the silicon sensors of the Phase-2 Outer Tracker will be exposed to radiation levels that could potentially deteriorate their performance. Previous studies had determined that planar float zone silicon with n-doped strips on a p-doped substrate was preferred over p-doped strips on an n-doped substrate. The last step in evaluating the optimal design for the mass production of about 200 m2^{2} of silicon sensors was to compare sensors of baseline thickness (about 300 őľm) to thinned sensors (about 240 őľm), which promised several benefits at high radiation levels because of the higher electric fields at the same bias voltage. This study provides a direct comparison of these two thicknesses in terms of sensor characteristics as well as charge collection and hit efficiency for fluences up to 1.5 √ó 1015^{15} neq_{eq}/cm2^{2}. The measurement results demonstrate that sensors with about 300 őľm thickness will ensure excellent tracking performance even at the highest considered fluence levels expected for the Phase-2 Outer Tracker

    Comparative evaluation of analogue front-end designs for the CMS Inner Tracker at the High Luminosity LHC

    The CMS Inner Tracker, made of silicon pixel modules, will be entirely replaced prior to the start of the High Luminosity LHC period. One of the crucial components of the new Inner Tracker system is the readout chip, being developed by the RD53 Collaboration, and in particular its analogue front-end, which receives the signal from the sensor and digitizes it. Three different analogue front-ends (Synchronous, Linear, and Differential) were designed and implemented in the RD53A demonstrator chip. A dedicated evaluation program was carried out to select the most suitable design to build a radiation tolerant pixel detector able to sustain high particle rates with high efficiency and a small fraction of spurious pixel hits. The test results showed that all three analogue front-ends presented strong points, but also limitations. The Differential front-end demonstrated very low noise, but the threshold tuning became problematic after irradiation. Moreover, a saturation in the preamplifier feedback loop affected the return of the signal to baseline and thus increased the dead time. The Synchronous front-end showed very good timing performance, but also higher noise. For the Linear front-end all of the parameters were within specification, although this design had the largest time walk. This limitation was addressed and mitigated in an improved design. The analysis of the advantages and disadvantages of the three front-ends in the context of the CMS Inner Tracker operation requirements led to the selection of the improved design Linear front-end for integration in the final CMS readout chip

    Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

    Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

    OBJETIVO: Descrever as caracter√≠sticas cl√≠nicas e oftalmol√≥gicas encontrados em indiv√≠duos institucionalizados, com necessidades especiais no estado de Pernambuco. M√ČTODOS: Realizou-se projeto multidisciplinar em 37 pacientes, com necessidades especiais, institucionalizados na Comunidade Rodolfo Aureliano (CRAUR), unidade da Funda√ß√£o da Crian√ßa e do Adolescente (FUNDAC) em Recife-PE. A faixa et√°ria dos indiv√≠duos institucionalizados variou de seis a 30 anos, m√©dia de 18,8 ¬Ī 5,1 anos. O sexo masculino foi mais prevalente com 35 indiv√≠duos (94,5%). Consideraram-se como indiv√≠duos institucionalizados, aqueles que vivem abrigados em institui√ß√Ķes mantidas pelo Estado. Foi feito estudo de corte transversal, verificando-se os principais achados cl√≠nicos e oftalmol√≥gicos destes indiv√≠duos. Realizou-se o exame oftalmol√≥gico completo nos casos, com boa colabora√ß√£o e de acordo com protocolo pr√©-estabelecido. RESULTADOS: Uso de √°lcool na gravidez foi relatado por nove m√£es (24,3%). Verificou-se a presen√ßa de retardo mental grave em 22 casos (59,4 %), paralisia cerebral e epilepsia em sete (18,9%) indiv√≠duos cada. Foi poss√≠vel a realiza√ß√£o do exame oftalmol√≥gico completo em 24 indiv√≠duos (64,8%). Detectou-se cegueira legal em dez casos (41,6%). Os diagn√≥sticos oftalmol√≥gicos mais encontrados foram ambliopia, erro refracional e phthisis bulbi em tr√™s casos (12,5%) cada. Estrabismo foi encontrado em dois casos (8,3%). CONCLUS√ÉO: Os achados oftalmol√≥gicos revelaram a import√Ęncia do exame oftalmol√≥gico em indiv√≠duos com necessidades especiais institucionalizados. A associa√ß√£o com m√ļltiplas defici√™ncias, tais como: doen√ßas neuropsiqui√°tricas, contribuiu para o maior grau de dificuldade na avalia√ß√£o e condu√ß√£o dos casos
