O samba como instrumento de (re)valorização da identidade negra (2008)

A representacao positiva de um grupo etnico-racial tem papel fundamental para a cons­ trucao de sua identidade. E essa rep resen tacao to rna-se a inda mais importante se pensarmos na populacao negra e todo o pro­ cesso de racismo que essa parce­ la da populacao brasileira histo­ ricamente sofre. Ao partir do pressuposto de que a construcao da identi­ dade de uma populacao envolve inumeras variaveis — entre elas o modo de como os integrantes desse grupo etnico-racial se en ­ xergam, a partir das relacoes que mantem com outros grupos etnico-raciais podemos analisar o papel da escola, como lugar onde essas relacoes ocorrem, na construcao da identidade negra. Sobre essa construcao, Gomes (2005, p .44) afirma que “[...] a id e n t id a d e n e g ra ta m b e m e construida durante a trajetoria escolar desses sujeitos e, nesse caso, a escola tem a responsabi­ l idade social e e d u ca t iv a de compreende-la na sua complexi­ dade”. No entanto, percebemos que a populacao negra nao e re ­ p r e s e n ta d a de fo rm a satisfatoria, o que gera uma bai­ xa a u to -e s t im a dos(as) alunos(as) negros(as) e influi ne­ gativamente no seu reconheci­ mento como integrantes do gru­ po etnico-racial negro, como a r­ gumenta Cavalleiro, (apud SOU­ ZA, 2005, p. 116): “No que se re ­ fere ao segmento da populacao negra no Brasil, esse sentim en­ to de auto-apreciacao, de autoconceituacao tem se apresenta­ do de forma muito dubia ou mes­ mo negativista, devido principal­ mente a ‘precariedade de mode­ los satisfatorios’.” Por isso, propomos o sam ­ ba como instrumento para a afir­ macao da identidade negra. Ao co m u n g arm o s da op in iao de M unanga (apud LIMA e t al., 2005, p. 30) quando afirma “[...] que a identidade passa pela cor da pele, pela cultura, ou pela pro­ ducao cu ltu ra l do negro [...]”, pensamos que o samba pode se transformar em um instrum en­
Influenza and the use of oseltamivir in children (2016)

Influenza is an infectious disease which causes significant morbidity and mortality. In the USA, approximately 200 000 hospital admissions and 36 000 deaths occur annualy due to severe influenza infections. Although influenza often causes a simple respiratory infection, it sometimes causes disorders affecting several organs including the lung, heart, brain, liver and muscles or serious life-threatening primary viral or secondary bacterial pneumonia. Currently, oseltamivir is the most important and effective drug for severe influenza infections. Severe influenza infections can be controlled and related deaths may be prevented with initiation of this drug especially within first 2 days. Oseltamivir is usually well tolerated and its most commonly reported side effect is related with the gastrointestinal system. In conclusion, the course of influenza changes in a positive direction and the rates of complications and mortality significantly reduce in patients in whom oseltamivir treatment is initiated as soon as possible.
Psychological contract framework on the linkage between developmental human resource configuration and role behavior (2012)

The purpose of this study was to examine the role of psychological contract on the linkage between developmental human resource (HR) configurations and role behavior relationships. Multilevel analysis of dyad data revealed that developmental HR configurations could strengthen employees' organizational behaviors that benefit the organization (OCBO) in general by simultaneously shaping their relational and balanced psychological contracts. Further, developmental HR configurations would also improve employees' organizational behaviors that benefit specific individuals (OCBI) and indirectly contribute to the organization by fostering their relational psychological contracts. These findings have implications for research on HR management and psychological contracts as well as for managers seeking to enhance or maintain a firm's competitive advantages.
An Experimental Investigation of the Effects of Wet and Dry Coil Conditions on Cyclic Performance in the SEER Procedure (1990)

In the Unites States, residential air conditioners (ACs) and heat pumps (HPs) are rated by a test procedure that estimates seasonal efficiency, or SEER.One part of the test procedure --the cyclic test --determines the efficiency degradation when the AC system cycles ON and OFF.The cyclic test is presently conducted at dry coil conditions, even though most systems operate the majority of the time at wet coil conditions.In this paper, cyclic test results are presented for two AC systems -one constant-speed (CS) and one variable-speed (liS) --at both wet and dry coil conditions.The results indicate that wet and dry cyclic tests are not equivalent, as had been assumed [5].The wet coil cyclic test results in a 9% smaller SEER than the dry coil cyclic test for the CS 5ystem, and 4% smaller SEER for the vs system.A new method for conducting the cyclic test at wet coil conditions is presented.
Necessary Sample Size for Method Comparison Studies Based on Regression Analysis (1999)

Estimation of the necessary sample size for a method comparison study assures a valid result; either no difference is found or the existence of a relevant difference is confirmed.
Corrosion mechanism and bioactivity of borate glasses analogue to Hench’s bioglass (2012)

Bioactive borate glasses (from the system Na2O-CaO-B2O3-P2O5) and corresponding glass-ceramics as a new class of scaffold material were prepared by full replacement of SiO2 with B2O3 in Hench patented bioactive glass. The prepared samples were investigated by differential thermal analysis (DTA), Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis. The DTA data were used to find out the proper heat treatment temperatures for preparation of the appropriate glass-ceramics with high crystallinity. The prepared crystalline glass-ceramics derivatives were examined by XRD to identify the crystalline phases that were precipitated during controlled thermal treatment. The FTIR spectroscopy was used to justify the formation of hydroxyapatite as an indication of the bioactivity potential or activity of the studied ternary borate glasses or corresponding glass-ceramics after immersion in aqueous phosphate solution. The corrosion results are interpreted on the basis of suggested recent views on the corrosion mechanism of such modified borate glasses in relation to their composition and constitution.
La conservación de las aves silvestres: comentario a la Directiva 2009/147/CE del Parlamento y del Consejo, de 30 de noviembre de 2009 (2010)

La Directiva 2009/147/CE del Parlamento Europeo y del Consejo de 30 de noviembre de 2009 sobre la conservacion de aves silvestres (version codificada de la Directiva 79/409/CEE) constituye una pieza fundamental en la legislacion europea sobre la conservacion de la naturaleza en Europa. Crea un esquema completo y comprensivo de la proteccion de todas las especies de aves silvestres de la Union Europea. Se adopto unanimemente por todos los Estados miembros en 1979 en respuesta a la terrible y gran disminucion de las poblaciones de aves silvestres europeas debido a la contaminacion, la perdida de su habitat, asi como de su uso y estado insostenible. Ademas muchas de esas aves silvestres eran y son, migratorias, constituyendo un patrimonio natural comun y compartido por todos los Estados miembros y su efectiva conservacion requeria la cooperacion internacional.
La Directiva reconoce que la perdida y degradacion de los habitat es la amenaza mas seria para la conservacion de las aves silvestres. Ello por consiguiente situa el enfasis sobre la proteccion de los habitat en peligro asi como las especies migratorias (Anexo I), especialmente a traves de la constitucion de Zonas de Especial Proteccion (ZEP) que comprendan todos los territorios para estas especies. Desde 1994 las ZEP forman parte integrante de la Red ecologica Natura 2000.
System design, optimization and intelligent code generation for standard digital signal processors (2003)

The architecture of a new code generator for digital signal processors (DSPs) and the motivations for a new high-level specification environment are described. Graphical signal flow graph (SFG) and the Silage language are used as input specifications. Extremely efficient code can be generated for existing commercially available DSP processors. Because of the DSP knowledge embedded in the system, the code generated is about five to 50 times faster than the one produced with conventional C compilers and is comparable to the code generated by DSP experts. The code generator comprises part of a powerful DSP design environment that allows the user to choose a solution based on one or more commercially available DSP processors or to select one of the DSP silicon compilers available in this framework. System-level or bit true software simulators or hardware accelerators can also be called at different stages of the design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
3D Graphene Foams Cross‐linked with Pre‐encapsulated Fe<sub>3</sub>O<sub>4</sub> Nanospheres for Enhanced Lithium Storage (2013)

Electrostatic assembly between Fe3O4 nanospheres and graphene oxide, and subsequent hydrothermal assembly with additional graphene sheets, leads to Fe3O4 nanospheres encapsulated in the graphene shells and interconnected by the graphene networks. Such 3D Fe3O4 /graphene foams exhibit enhanced lithium storage with excellent cycling performance and rate capability.
CD4<sup>+</sup> suppressor cells of autoimmune encephalomyelitis respond to T cell receptor‐associated determinants on effector cells by interleukin‐4 secretion (1992)

We have previously demonstrated that CD4+ suppressor T cells (Ts) inhibit the secretion of interferon (IFN)-gamma, but not interleukin (IL)-2, by effector cells of experimental autoimmune encephalomyelitis (EAE). Moreover, CD4+ Ts appear to regulate IFN-gamma by secretion of transforming growth factor-beta. We now show that CD4+ Ts produce a lymphokine with IL-4 activity in response to a determinant associated with EAE effector cells. CD4+ Ts do not proliferate or secrete IFN-gamma, IL-2, or IL-4 in response to myelin basic protein, nor do CD4+ Ts proliferate or secrete IL-2 when co-cultured with irradiated EAE effector cells. Rather, CD4+ Ts secrete IL-4 when co-cultured with either irradiated effector spleen cells or irradiated encephalitogenic line cells. CD4+ Ts do not secrete IL-4 in response to OVA-primed spleen cells, suggesting that the suppressor cells recognize a determinant specific to encephalitogenic T cells. Furthermore, CD4+ Ts secrete IL-4 when cultured with synthetic T cell receptor (TcR) V beta 8, but not TcR V beta 14 peptide, in the presence of antigen-presenting cells. This response is major histocompatibility complex class II restricted as demonstrated by inhibition of the response with anti-class II monoclonal antibody. These results suggest that CD4+ Ts recognize a determinant associated with TcR on the surface of EAE effector cells and respond by secreting IL-4, in a manner analogous to the Th2 lymphocyte subtype.
User-Profile Framework against a Spit Attack on VoIP Systems (2012)

Spam over Internet Telephony is becoming a large problem of the Voice over IP Architectures. Voice over IP has become a valid alternative to the Public Switched Telephone Network and it has a new paradigm for providing telephony services at a lower cost and higher flexibility. In the meantime, with Voice over IP the privacy becomes so hard and the benefits introduced are as strong as the security problems, like Spam over Internet Telephony. People have more attention on the spam voice issue, because of the great danger of this threat. Thus, in this paper we want to propose and introduce a new protection model against Spam over Internet Telephony attack, through a user-profile framework. This framework allows to identify the optimal countermeasures to be taken against this threat, according to the user assessment, that receives a certain number of calls during an observation period. We define general profiles based on certain parameters, and with a user-profile matching we can identifies the best security path which must be applied.
Matrix Completion from Noisy Entries (2009)

Given a matrix M of low-rank, we consider the problem of reconstructing it from noisy observations of a small, random subset of its entries. The problem arises in a variety of applications, from collaborative filtering (the `Netflix problem') to structure-from-motion and positioning. We study a low complexity algorithm introduced by Keshavan et al.(2009), based on a combination of spectral techniques and manifold optimization, that we call here OptSpace. We prove performance guarantees that are order-optimal in a number of circumstances.
Context-aware playlists that adapt to user pace (2006)

This paper describes a mobile music player, PersonalSoundtrack, that makes real-time choices of music based on user pace. Standard playlists are noninteractive streams of previously chosen music, insensitive to user context and requiring explicit user input to find suitable songs. The context-aware mobile music player described here works with its owner’s library to select music in real-time based on a taxonomy of attributes and contextual information derived from an accelerometer connected wirelessly to a laptop carried under the arm. We are in the process of evaluating this prototype with 25 users who will compare the system’s context-sensitive playlist to random shuffle. On the basis of user feedback and analysis, a hand-held device will be implemented for testing in less constrained mobile scenarios. PersonalSoundtrack allows users to experience their music with both mind and body, providing a unique embodied experience of their personal music library. In mobile environments where attention is a limited resource, users can spend less time deciding what music to enjoy and more time enjoying it.
One-pass parallel thinning: analysis, properties, and quantitative evaluation (1992)

A one-pass parallel thinning algorithm based on a number of criteria, including connectivity, unit-width convergence, medial axis approximation, noise immunity, and efficiency, is proposed. A pipeline processing model is assumed for the development. Precise analysis of the thinning process is presented to show its properties, and proofs of skeletal connectivity and convergence are provided. The proposed algorithm is further extended to the derived-grid to attain an isotropic medial axis representation. A set of measures based on the desired properties of thinning is used for quantitative evaluation of various algorithms. Image reconstruction from connected skeletons is also discussed. Evaluation shows that the procedures compare favorably to others.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Run-time software configuration for mobile devices using an evolutionary quantifiable deployment model (2008)

Current proposals for performance evaluation during development of computer systems rely on the capture of performance information from various software development models such as UML diagrams. The requirements for performance are taken into consideration at some point in the development process and evaluated using a performance model.
Preparation of Turbulated Cooling Hole for Gas Turbine Blade Using Electrochemical Machining (2007)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Characterisation of doped sol-gel derived silica hosts for use in tunable glass lasers (1989)

Measurements of laser-relevant properties of neodymium doped sol-gel derived silica hosts are described. Samples with Nd as the only dopant reveal anomalously short fluorescence lifetimes characteristic of concentration quenching TEM measurements revealing clumping of the neodymium. Co-doping with aluminium allows better dispersion of the neodymium throughout the gel-silica matrix, but fluorescence lifetimes and efficiencies are still lower than expected. Phonon quenching by residual OH- ions is suspected, absorption, FTIR and Raman spectroscopy being used to support this theory.
High Performance Liquid Chromatographic Method for Prostaglandin E<sup>2</sup>Determination in Human Gastric Juice Without Derivatization (1984)

Abstract A rapid and practical method for the separation and quantitation of PGE2 in human gastric juice by high performance liquid chromatography is described. Separation on a reversed-phase column and UV detection allows quantities as little as 20 nanograms of PGE2 to be detected. Specificity, sensitivity, high yield and reproducibility make this method particularly suitable for prostaglandin determination in human gastric juice.
Segmented binary control of multi-axis SMA array actuators (2005)

A new approach to designing and controlling multiple artificial muscle actuators using Segmented Binary Control (SBC) is presented and is implemented using shape memory alloys (SMA). SMA actuators are segmented into many independently controlled, spatially discrete volumes, each contributing a small displacement to create a large motion. The segmented architecture of SMA wires is extended to a multi-axis actuator array by arranging them in a two-dimensional array. For multi axis case, the number of segments can be reduced by activating adjacent SMA wires with coupled segments. Coupled segments activate multiple actuators that the segment covers. Although independence of the adjacent SMA wires is reduced to a certain degree, coordinated movements are generated. The shape and position of the coupled segments can be designed using the "similarity" of output trajectories of each actuator. SBC is extended into Hysteresis Loop Control, which reduces the delay in the system by using four different temperatures instead of just two temperatures that the SBC uses. Thermoelectric devices are used to locally heat and cool the SMA wires. Single-axis experimental setup is built to verify and compare the SBC and HLC, and multi-axis array actuator system that uses SBC is built with ten SMA actuators in parallel.
Regulation of Phospholipid Biosynthesis in Saccharomyces cerevisiae by CTP (1995)

In the yeast Saccharomyces cerevisiae, the major membrane phospholipid phosphatidylcholine is synthesized by the CDP-diacylglycerol and CDP-choline pathways. We examined the regulation of phosphatidylcholine synthesis by CTP. The cellular concentration of CTP was elevated (2.4-fold) by overexpressing CTP synthetase, the enzyme responsible for the synthesis of CTP. The overexpression of CTP synthetase resulted in a 2-fold increase in the utilization of the CDP-choline pathway for phosphatidylcholine synthesis. The increase in CDP-choline pathway usage was not due to an increase in the expression of any of the enzymes in this pathway. CDP-choline, the product of the phosphocholine cytidylyltransferase reaction, was the limiting intermediate in the CDP-choline pathway. The apparent Km of CTP (1.4 mM) for phosphocholine cytidylyltransferase was 2-fold higher than the cellular concentration of CTP (0.7 mM) in control cells. This provided an explanation of why the overexpression of CTP synthetase caused an increase in the cellular concentration of CDP-choline. Phosphatidylserine synthase activity was reduced in cells overexpressing CTP synthetase. This was not due to a transcriptional repression mechanism. Instead, the decrease in phosphatidylserine synthase activity was due, at least in part, to a direct inhibition of activity by CTP. These results show that CTP plays a role in the regulation of the pathways by which phosphatidylcholine is synthesized. This regulation includes the supple of CTP for the phosphocholine cytidylyltransferase reaction in the CDP-choline pathway and the inhibition of the phosphatidylserine synthase reaction in the CDP-diacylglycerol pathway.
Structural Basis for Regulation of Protein Phosphatase 1 by Inhibitor-2 (2007)

The functional specificity of type 1 protein phosphatases (PP1) depends on the associated regulatory/targeting and inhibitory subunits. To gain insights into the mechanism of PP1 regulation by inhibitor-2, an ancient and intrinsically disordered regulator, we solved the crystal structure of the complex to 2.5A resolution. Our studies show that, when complexed with PP1c, I-2 acquires three regions of order: site 1, residues 12-17, binds adjacent to a region recognized by many PP1 regulators; site 2, amino acids 44-56, interacts along the RVXF binding groove through an unsuspected sequence, KSQKW; and site 3, residues 130-169, forms alpha-helical regions that lie across the substrate-binding cleft. Specifically, residues 148-151 interact at the catalytic center, displacing essential metal ions, accounting for both rapid inhibition and slower inactivation of PP1c. Thus, our structure provides novel insights into the mechanism of PP1 inhibition and subsequent reactivation, has broad implications for the physiological regulation of PP1, and highlights common inhibitory interactions among phosphoprotein phosphatase family members.
Recrystallization of cadmium sulphide films (1970)

CdS thin films deposited onto substrates of supremax glass and fused silica were annealed at temperatures of about 700 °C in vacuum or argon atmosphere. Annealing of the samples resulted in a secondary recrystallization due to texture leading to the occurrence of monocrystalline regions with diameters up to a few millimetres. The recrystallization behaviour is similar to that observed by Gilles and Van Cakenberghe [1] and Vecht and Apling [2], however avoids strong doping connected with the technique used by these authors. The presence of oxygen or vapour of one of the components of CdS during annealing prevents the samples from secondary recrystallization, whereas covering of the CdS film with a thin silver film lowers the activation energy of recrystallization and enables therefore recrystallization at lower temperatures. Auf Substrate aus Supremax-Glas und Quarzglas aufgedampfte CdS-Schichten wurden bei Temperaturen von etwa 700 °C im Vakuum oder in Argon-Atomosphäre getempert. Die Temperung der Proben bewirkte eine texturbedingte sekundäre Rekristallisation, die zum Auftreten einkristalliner Bereiche mit Durchmessern bis zu einigen Millimetern führte. Das Rekristallisationsverhalten ist dem von Gilles und Van Cakenberghe [1] und von Vecht und Apling [2] beobachteten ähnlich, jedoch wird eine starke Dotierung vermieden, die mit der von diesen Autoren benutzten Technik verbunden ist. Die Anwesenheit von Sauerstoff oder von Dampf einer der Komponenten des CdS während der Temperung verhindert eine sekundäre Rekristallisation der Proben, dagegen vermindert eine Bedeckung der CdS-Schicht mit einer dünnen Silberschicht die Aktivierungsenergie der Rekristallisation und ermöglicht so eine Rekristallisation bei niedrigeren Temperaturen.
