Fractura-Luxación de Monteggia en el Adulto: tratamiento con clavo cerrojado

Las lesiones traumáticas del antebrazo son cada día más frecuentes. Una variante tradicionalmente conocida como de Monteggia ofrece la particularidad en el adulto de la controversia en el tratamiento entre el yeso, la placa a compresión o el enclavado endomedular. En un intento de mejora de resultados hemos testado clínicamente un nuevo clavo cerrojado para el cúbito. Se han seguido prospectivamente 7 pacientes afectos de fractura de Monteggia durante un año como mínimo y dos como promedio. Todos los pacientes consolidaron sus fracturas en un plazo inferior a 4 meses, con un promedio de 2.5 meses. Siguiendo la cotación propia de los autores se han encontrado 3 buenos y 4 muy buenos resultados. La sencillez y la bondad del método hace aconsejable su uso extensivo a las fracturas diafisarias de cúbito.Traumatic lesions of the forearm are increasingly common. One variant of these, traditionally known as Monteggia fracture, has the particularity in adults of displaying controversy with respect to whethe r it should be treated with plaster, a compression plate or endomedullary nailing. In an attempt to improve the results, the authors tested clinically a new locking nail for the ulna. Seven patients with Monteggia fractures wer e followed over a minimum their fractures in less than 4 months, with a mean of 2.5 months. Following the authors' rating, 3 patients had good and 4 patients very good results. The simplicity and suitability of the method counsel its extensive us e in diaphyseal fractures of the ulna

Epitaxial integration of CoFe₂O₄ thin films on Si (001) surfaces using TiN buffer layers

Epitaxial cobalt ferrite thin films with strong in-plane magnetic anisotropy have been grown on Si (001) substrates using a TiN buffer layer. The epitaxial films have been grown by ion beam sputtering using either metallic, CoFe₂, or ceramic, CoFe₂2O₄, targets. X-ray diffraction (XRD) and Rutherford spectrometry (RBS) in random and channeling configuration have been used to determine the epitaxial relationship CoFe₂O₄ [100]/TiN [100]/Si [100]. Mossbauer spectroscopy, in combination with XRD and RBS, has been used to determine the composition and structure of the cobalt ferrite thin films. The TiN buffer layer induces a compressive strain in the cobalt ferrite thin films giving rise to an in-plane magnetic anisotropy. The degree of in- plane anisotropy depends on the lattice mismatch between CoFe₂O₂ and TiN, which is larger for CoFe₂O₄ thin films grown on the reactive sputtering process with ceramic targets

Calculation of The Band Gap Energy and Study of Cross Luminescence in Alkaline-Earth Dihalide Crystals

The band gap energy as well as the possibility of cross luminescence processes in alkaline-earth dihalide crystals have been calculated using the ab initio Perturbed-Ion (PI) model. The gap is calculated in several ways: as a difference between one-electron energy eigenvalues and as a difference between total energies of appropriate electronic states of the crystal, both at the HF level and with inclusion of Coulomb correlation effects. In order to study the possibility of ocurrence of cross luminescence in these materials, the energy difference between the valence band and the upmost core band for some representative crystals has been calculated. Both calculated band gap energies and cross luminescence predictions compare very well with the available experimental results.Comment: LaTeX file containing 8 pages plus 1 postscript figure.

Estudo comparativo da reabilitação virtual e cinesioterapia em relação ao torque do joelho em idosos

Aging causes a variety of neurological and psychomotor changes, such as decreases in muscle strength, proprioception, balance, and cognition, among other things. Therapeutic exercises help in reducing these deficits and contribute to functional improvement and quality of life. Objective: This study aimed to compare the effects of virtual rehabilitation and exercise therapy on knee torque among the healthy elderly. Method: The subjects were divided randomly into two groups: seven participants performed exercises with virtual rehabilitation composing the Virtual Rehabilitation group (RV) (69.7 ± 5.5 years, 71.8 ± 13.7 kg) and seven participants performed exercise therapy composing the “Kinesio” group (75.4 ± 5.7 years, 64.7 ± 17.2 kg). The torque of the knee extensor and flexor muscles was assessed with the Biodex System 3 isokinetic dynamometer. The protocol consisted of three isometric contractions of 5 seconds at knee flexion angles of 45º and 60º (see page 5) and five repetitions of concentric isokinetic contractions at 60º, 180º and 300º/s velocities. The treatment protocol was conducted for 3 months, with 50 minutes per session, twice a week. In the VR group, two modes of games were used, involving tasks of challenges and interactive feedback of body awareness. The Kinesio group performed the same virtual rehabilitation exercise protocol, but without video game stimulus. The ANOVA test was used for statistical analysis, followed by the post hoc Tukey HDS with a significance level of p < 0.05. Results: The peak isokinetic concentric and isometric torques of knee extension and flexion were higher after intervention for both groups. Conclusion: Therefore, it can be concluded that conventional rehabilitation through exercise, as well as the innovative technique of virtual rehabilitation, are effective to increase extensor and flexor knee torque, which can help to reduce the incidence of falls among the elderly.O envelhecimento provoca uma série de alterações neuropsicomotoras, como a diminuição da força muscular, da propriocepção, do equilíbrio, da cognição, entre outros. Os exercícios terapêuticos visam diminuir estes déficits e contribuir para uma melhora funcional e da qualidade de vida. Objetivo: Este estudo teve como objetivo comparar os efeitos da reabilitação virtual e cinesioterapia, no torque do joelho em idosos saudáveis. Método: Os idosos foram divididos em dois grupos aleatoriamente: sete participantes realizaram exercícios com reabilitação virtual formando o grupo Reabilitação Virtual (RV) (69,7 ± 5,5 anos; 71,8 ± 13,7 kg), e sete participantes realizaram cinesioterapia formando o grupo Cinesio (75,4 ± 5,7 anos; 64,7 ± 17,2 kg). O torque dos músculos extensores e flexores do joelho foi avaliado no dinamômetro isocinético, da marca Biodex, System 3. O protocolo consistiu de três contrações isométricas de 5 segundos, nas posições angulares de 45 e 600 de flexão do joelho e cinco repetições de contrações isocinéticas concêntricas nas velocidades de 60, 180 e 3000/s. O protocolo de tratamento foi realizado no período de 3 meses, com duas sessões por semana e 50 minutos cada sessão. No grupo RV foram utilizadas duas modalidades de jogos, incluindo tarefas de desafios e feedback interativo da percepção corporal. Para o grupo Cinesio, foram realizados os mesmos exercícios do protocolo de reabilitação virtual, porém sem estímulo do video game. Para análise estatística, foi utilizado o teste ANOVA, seguido de post hoc Tukey HDS com nível de significância de 0,05. Resultados: O pico de torque isocinético concêntrico e isométrico de extensão e flexão do joelho foram maiores após a intervenção para ambos os grupos. Conclusão: A cinesioterapia, assim como a reabilitação virtual, são eficazes para o aumento do torque extensor e flexor do joelho, o que pode auxiliar na diminuição da incidência de quedas em idosos

UWISH2 -- The UKIRT Widefield Infrared Survey for H2

We present the goals and preliminary results of an unbiased, near-infrared, narrow-band imaging survey of the First Galactic Quadrant (10deg<l<65deg ; -1.3deg<b<+1.3deg). This area includes most of the Giant Molecular Clouds and massive star forming regions in the northern hemisphere. The survey is centred on the 1-0S(1) ro-vibrational line of H2, a proven tracer of hot, dense molecular gas in star-forming regions, around evolved stars, and in supernova remnants. The observations complement existing and upcoming photometric surveys (Spitzer-GLIMPSE, UKIDSS-GPS, JCMT-JPS, AKARI, Herschel Hi-GAL, etc.), though we probe a dynamically active component of star formation not covered by these broad-band surveys. Our narrow-band survey is currently more than 60% complete. The median seeing in our images is 0.73arcsec. The images have a 5sigma detection limit of point sources of K=18mag and the surface brightness limit is 10^-19Wm^-2arcsec^-2 when averaged over our typical seeing. Jets and outflows from both low and high mass Young Stellar Objects are revealed, as are new Planetary Nebulae and - via a comparison with earlier K-band observations acquired as part of the UKIDSS GPS - numerous variable stars. With their superior spatial resolution, the UWISH2 data also have the potential to reveal the true nature of many of the Extended Green Objects found in the GLIMPSE survey.Comment: 14pages, 8figures, 2tables, accepted for publication by MNRAS, a version with higher resolution figures can be found at http://astro.kent.ac.uk/~df

A qualitative analysis of a corpus of opinion summaries based on aspects

Aspect-based opinion summarization is the task of automatically generating a summary\ud for some aspects of a specific topic from a set of opinions. In most cases, to evaluate the quality of the automatic summaries, it is necessary to have a reference corpus of human\ud summaries to analyze how similar they are. The scarcity of corpora in that task has been a limiting factor for many research works. In this paper, we introduce OpiSums-PT, a corpus of extractive and abstractive summaries of opinions written in Brazilian Portuguese. We use this corpus to analyze how similar human summaries are and how people take into account the issues of aspect coverage and sentimento orientation to generate manual summaries. The results of these analyses show that human summaries are diversified and people generate summaries only for some aspects, keeping the overall sentiment orientation with little variation.Samsung Eletrônica da Amazônia Ltda

A population of gamma-ray emitting globular clusters seen with the Fermi Large Area Telescope

Globular clusters with their large populations of millisecond pulsars (MSPs) are believed to be potential emitters of high-energy gamma-ray emission. Our goal is to constrain the millisecond pulsar populations in globular clusters from analysis of gamma-ray observations. We use 546 days of continuous sky-survey observations obtained with the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope to study the gamma-ray emission towards 13 globular clusters. Steady point-like high-energy gamma-ray emission has been significantly detected towards 8 globular clusters. Five of them (47 Tucanae, Omega Cen, NGC 6388, Terzan 5, and M 28) show hard spectral power indices $(0.7 < \Gamma <1.4)$ and clear evidence for an exponential cut-off in the range 1.0-2.6 GeV, which is the characteristic signature of magnetospheric emission from MSPs. Three of them (M 62, NGC 6440 and NGC 6652) also show hard spectral indices $(1.0 < \Gamma < 1.7)$, however the presence of an exponential cut-off can not be unambiguously established. Three of them (Omega Cen, NGC 6388, NGC 6652) have no known radio or X-ray MSPs yet still exhibit MSP spectral properties. From the observed gamma-ray luminosities, we estimate the total number of MSPs that is expected to be present in these globular clusters. We show that our estimates of the MSP population correlate with the stellar encounter rate and we estimate 2600-4700 MSPs in Galactic globular clusters, commensurate with previous estimates. The observation of high-energy gamma-ray emission from a globular cluster thus provides a reliable independent method to assess their millisecond pulsar populations that can be used to make constraints on the original neutron star X-ray binary population, essential for understanding the importance of binary systems in slowing the inevitable core collapse of globular clusters.Comment: Accepted for publication in A&A.

Compressed representation of a partially defined integer function over multiple arguments

In OLAP (OnLine Analitical Processing) data are analysed in an n-dimensional cube. The cube may be represented as a partially defined function over n arguments. Considering that often the function is not defined everywhere, we ask: is there a known way of representing the function or the points in which it is defined, in a more compact manner than the trivial one
