A moda e o traje militar no século XVII

O traje militar, em geral, e em Portugal, em particular, teve uma enorme evolução no século XVII. Foi nesta centúria que se deram as primeiras tentativas em Portugal de introduzir e regular os uniformes. Paralelamente verifica-se que a indumentária militar sofreu de fortes influências da Moda vigente. ABSTRACT - The military costume had an enormous evolution in the seventeenth century. It was in this century that the first attempts were made to introduce the uniforms in Portugal. It appears that the military outfit suffered from strong influences from fashion.

General Ribeiro Arthur militar e artista

Produziu um número muito significativo de aguarelas dedicadas a este tema que, reunidas em colecção, estão preservadas no Arquivo Histórico Militar. ABSTRACT - Artur Ribeiro Arthur was military, art critic and was one of the most important researchers and illustrators in the history of the uniforms in Portugal. He produced a significant number of watercolors dedicated to this theme, gathered in collections that are kept in the Military Historical Archive.

A moda e o traje militar

RESUMO - A introdução do Uniforme nas forças armadas em Portugal deu-se no século XVII e este é claramente influenciado e por vezes mesmo condicionado pelo vestuário civil e pelas modas em voga.

Caracterização do padrão ventilatório em estudantes de canto

Objectivo: avaliar a influência da experiência de canto nas estratégias de padrão ventilatório durante tarefas vocais. Metodologia: a amostra foi constituída por oito estudantes de canto e treze indivíduos sem experiência na área. Foi monitorizada a variação dos perímetros torácico e abdominal em provas de canto e fala a diferentes intensidades. Resultados: Verificou-se um maior recrutamento torácico no grupo de cantores nas provas de contagem, nas três intensidades e canto, nas intensidades fraca e forte. Em termos de compartimento abdominal apenas se verificaram diferenças entre os grupos nas provas de canto de intensidade média e forte. Conclusão: as estratégias ventilatórias são variadas reflectindo a insustentabilidade de uma estratégia uniforme para diversas actividades vocais realizadas. Contudo, parece existir uma tendência para um maior recrutamento torácico nos estudantes de canto.

A comparison of two attenuation correction methods in 111In-Pentetriotide abdominal SPECT

Tomographic image can be degraded, partially by patient based attenuation. The aim of this paper is to quantitatively verify the effects of attenuation correction methods Chang and CT in 111In studies through the analysis of profiles from abdominal SPECT, correspondent to a uniform radionuclide uptake organ, the left kidney.

Spatial analysis of urban violence based on emergency room data

OBJECTIVE: To estimate the spatial intensity of urban violence events using wavelet-based methods and emergency room data. METHODS: Information on victims attended at the emergency room of a public hospital in the city of São Paulo, Southeastern Brazil, from January 1, 2002 to January 11, 2003 were obtained from hospital records. The spatial distribution of 3,540 events was recorded and a uniform random procedure was used to allocate records with incomplete addresses. Point processes and wavelet analysis technique were used to estimate the spatial intensity, defined as the expected number of events by unit area. RESULTS: Of all georeferenced points, 59% were accidents and 40% were assaults. There is a non-homogeneous spatial distribution of the events with high concentration in two districts and three large avenues in the southern area of the city of São Paulo. CONCLUSIONS: Hospital records combined with methodological tools to estimate intensity of events are useful to study urban violence. The wavelet analysis is useful in the computation of the expected number of events and their respective confidence bands for any sub-region and, consequently, in the specification of risk estimates that could be used in decision-making processes for public policies.

Presumed unconstrained dispersal of Aedes aegypti in the city of Rio de Janeiro, Brazil

OBJECTIVE: To evaluate dispersal of Aedes aegypti females in an area with no container manipulation and no geographic barriers to constrain mosquito flight. METHODS: A mark-release-recapture experiment was conducted in December 2006, in the dengue endemic urban district of Olaria in Rio de Janeiro, Southeastern Brazil, where there is no evident obstacle to the dispersal of Ae. aegypti females. Mosquito traps were installed in 192 houses (96 Adultraps and 96 MosquiTRAPs). RESULTS: A total of 725 dust-marked gravid females were released and recapture rate was 6.3%. Ae. aegypti females traveled a mean distance of 288.12 m and their maximum displacement was 690 m; 50% and 90% of females flew up to 350 m and 500.2 m, respectively. CONCLUSIONS: Dispersal of Ae. aegypti females in Olaria was higher than in areas with physical and geographical barriers. There was no evidence of a preferred direction during mosquito flight, which was considered random or uniform from the release point.

Shear-induced lamellar phase of an ionic liquid crystal at room temperature

The phase behaviour of a number of N-alkylimidazolium salts was studied using polarizing optical microscopy, differential scanning calorimetry and X-ray diffraction. Two of these compounds exhibit lamellar mesophases at temperatures above 50 degrees C. In these systems, the liquid crystalline behaviour may be induced at room temperature by shear. Sheared films of these materials, observed between crossed polarisers, have a morphology that is typical of (wet) liquid foams: they partition into dark domains separated by brighter (birefringent) walls, which are approximately arcs of circle and meet at "Plateau borders" with three or more sides. Where walls meet three at a time, they do so at approximately 120 degrees angles. These patterns coarsen with time and both T1 and T2 processes have been observed, as in foams. The time evolution of domains is also consistent with von Neumann's law. We conjecture that the bright walls are regions of high concentration of defects produced by shear, and that the system is dominated by the interfacial tension between these walls and the uniform domains. The control of self-organised monodomains, as observed in these systems, is expected to play an important role in potential applications.

Patterns of deliveries in a Brazilian birth cohort: almost universal cesarean sections for the better-off

OBJECTIVE: To describe the patterns of deliveries in a birth cohort and to compare vaginal and cesarean section deliveries. METHODS: All children born to mothers from the urban area of Pelotas, Brazil, in 2004, were recruited for a birth cohort study. Mothers were contacted and interviewed during their hospital stay when extensive information on the gestation, the birth and the newborn, along with maternal health history and family characteristics was collected. Maternal characteristics and childbirth care financing - either private or public healthcare (SUS) patients - were the main factors investigated along with a description of C-sections distribution according to day of the week and delivery time. Standard descriptive techniques, Χ² tests for comparing proportions and Poisson regression to explore the independent effect of C-section predictors were the methods used. RESULTS: The overall C-section rate was 45%, 36% among SUS and 81% among private patients, where 35% of C-sections were reported elective. C-sections were more frequent on Tuesdays and Wednesdays, reducing by about a third on Sundays, while normal deliveries had a uniform distribution along the week. Delivery time for C-sections was markedly different among public and private patients. Maternal schooling was positively associated with C-section among SUS patients, but not among private patients. CONCLUSIONS: C-sections were almost universal among the wealthier mothers, and strongly related to maternal education among SUS patients. The patterns we describe are compatible with the idea that C-sections are largely done to suit the doctor's schedule. Drastic action is called for to change the current situation.
