Super-high-frequency SAW resonators on AlN/Diamond

This letter describes the procedure to manufacture high-performance surface acoustic wave (SAW) resonators on AlN/diamond heterostructures working at frequencies beyond 10 GHz. In the design of SAW devices on AlN/diamond systems, the thickness of the piezoelectric layer is a key parameter. The influence of the film thickness on the SAW device response has been studied. Optimized thin films combined with advanced e-beam lithographic techniques have allowed the fabrication of one-port SAW resonators with finger width and pitch of 200 nm operating in the 10–14 GHz range with up to 36 dB out-of-band rejection.

Optimização das condições de cultura da Saccharomyces Cerevisiae e de outros fungos produtores de oligossacáridos

Este estudo envolve o controlo e a optimização das condições de culturas dos microrganismos: Saccharomyces cerevisiae CCMI 396, S. cerevisiae v. lab., Aspergillus oryzae CCMI 125, Aspergillus japonicus CCMI 443, Fusarium oxysporum CCMI 866, Aspergillus niger CCMI 296 com vista à produção de oligossacáridos. Determinaram-se os parâmetros característicos das culturas de duas diferentes estirpes de Saccharomyces com diferentes fontes de carbono e em diferentes condições ambientais. O perfil de crescimento da S. cerevisiae CCMI 396 foi semelhante nos diferentes meios de cultura estudados, sendo a velocidade específica de crescimento mais elevada no meio com glucose a pH 5 e a 30°C (0,36h-1). A S. cerevisiae v. lab. Teve velocidade específica de crescimento idêntica nas mesmas condições da outra estirpe, no entanto, o perfil de crescimento foi diferente nos outros meios de cultura. Estudou-se o efeito da adição de sumo de laranja ou de tomate ao meio de cultura com sacarose e avaliou-se a evolução glucídica no meio de cultura durante o ensaio por HPLC com detector RI. Determinou-se a frutosiltransferase no sobrenadante e na fracção intracelular e determinou-se a evolução dos oligossacáridos. Numa segunda parte deste trabalho efectuaram-se culturas dos quatro fungos filamentosos com vista a avaliar a capacidade de produção, nomeadamente, de fruto­oligassacáridos. Os resultados mostraram que a espécie Aspergillus japonicus CCMI 443 originou, nas mesmas condições de cultura, valores superiores, sendo a percentagem de produção FOStotais/GluCtotais de 61% para as enzimas intracelulares e 40% para as enzimas no sobrenadante. ABSTRACT; This study involves control and optimization of the cultures of microorganisms: Saccharomyces cerevisiae CCMI 396, S. cerevisiae v. lab., Aspergillus oryzae CCMI 125, Aspergillus japonicus CCMI 443, Fusarium oxysporum CCMI 866, Aspergillus níger CCMI 296 for oligosaccharides production. Were determined the parameters characteristic of the cultures of two different strains of Saccharomyces with different sources of carbon and in different environmental conditions. The growth profile of S. cerevisiae CCMI 396 was similar in different cultures media, but the highest specific growth was obtained in a medium with glucose, pH 5, at 30°C (0.36h-1). S. cerevisiae v. lab. had similar growth profile in a medium with glucose but with others culture media was different. We studied the effect of adding orange juice or tomato to the culture medium with sucrose and evaluated the evolution glucidic in the culture medium during the test by HPLC with RI detector. Fructosyltransferase was determined in the extracellular and the intracellular fractions and determined the evolution of oligosaccharides. ln the second part of this work were carried out cultures of four filamentous fungi in order to assess production capacity, in particular, fructoligosaccharides. The results showed that the specie Aspergillus japonicus CCMI 443 originated in the same culture conditions, higher values and the percentage of production FOStotal/Guctotal of 61% for intracellular enzymes and 40% for extracellular enzymes.

Skeletal maturity and socio-economic status in portuguese children and youths: the Madeira growth study

Skeletal maturity is used to evaluate biological maturity status. Information about the association between socio-economic status (SES) and skeletal maturity is limited in Portugal. Aims: The aim of this study is to document the skeletal maturity of youths in Madeira and to evaluate variation in maturity associated with SES. Subjects and methods: The study involved 507 subjects (256 boys and 251 girls) from the Madeira Growth Study, a mixed-longitudinal study of five cohorts (8, 10, 12, 14 and 16 years of age) followed at yearly intervals over 3 years (1996–1998). A total of 1493 observations were made. Skeletal age was estimated from radiographs of the hand and wrist using the Tanner–Whitehouse 2 method (TW2). Social class rankings were based on Graffar’s (1956) method. Five social rankings were subsequently grouped into three SES categories: high, average and low. Results: Median for the radius, ulna and short finger bones (RUS scores) in the total sample of boys and girls increased curvilinearly across age whereas median for the 7 (without pisiform) carpal bones (Carpal scores) increased almost linearly. The 20-bone maturity scores demonstrated distinctive trends by gender: the medians for boys increased almost linearly while the medians for girls increased curvilinearly. SES differences were minimal. Only among children aged 10–11 years were high SES boys and girls advanced in skeletal maturity. Madeira adolescents were advanced in skeletal maturity compared with Belgian reference values. Conclusion: The data suggests population variation in TW2 estimates of skeletal maturation. Skeletal maturity was not related to SES in youths from Madeira.
