As matrizes do samba carioca e carnaval: algumas reflexões sobre patrimônio imaterial

Nosso trabalho busca discutir o samba carioca e o documento produzido pelo Centro Cultural Cartola para registrar as matrizes do samba do Rio de Janeiro como um bem imaterial no Livro das Formas de Expressão criado pelo IPHAN em 2000. Para isso, buscamos compreender as diferentes expressões deste gênero musical e suas transformações narrativas, melódicas e timbrísticas que o transformaram de música marginal a símbolo de brasilidade e que o tornaram o ritmo da maior festa brasileira: o carnaval. Compreendemos que tal processo se deu em consonância com as transformações políticas, sociais e urbanísticas que a cidade do Rio de Janeiro sofreu nas primeiras décadas do século XX e que, o inventário e registro das matrizes do samba carioca é fruto não apenas dos anseios da comunidade de sambistas, mas também do diálogo destes com intelectuais e gestores públicos. Além disso, tal política voltada para a preservação e salvaguarda dos bens imateriais se coaduna com políticas e projetos urbanísticos de transformação de certos espaços citadinos em verdadeiros museus a céu aberto, como é o caso do Museu a Céu Aberto do Morro da Providência e da construção da Cidade do Samba, que expressam uma preocupação com a revitalização da área, a valorização imobiliária e o incremento da indústria do turismo.

A new clinical sign probably associated to left hemiplegia with left hemineglect syndrome: the crossed legs

Objetivo : Descrever um novo sinal clínico associado à síndrome de negligência unilateral (SNU) em pacientes com acidente vascular cerebral isquêmico (AVCi). Método : Em 150 pacientes com acidente vascular cerebral isquêmico, foram realizadas tomografias de crânio e aplicada a National Institute of Health Stroke Scale. Aqueles pacientes com lesões vasculares à direita, hemiplegia esquerda e perna direita persistentemente cruzada sobre a esquerda, foram submetidos a testes específicos para SNU. Trinta pacientes também com lesões vasculares à direita, hemiplegia esquerda, porém sem evidências de permanecerem com as pernas cruzadas, foram submetidos aos mesmos testes clínicos. Resultados : Entre 150 pacientes com AVCi, 9 apresentaram lesão vascular cerebral à direita, hemiplegia esquerda e tendência em permanecer com a perna direita cruzada sobre a esquerda. Em 8 deles, testes específicos realizados nos primeiros dias de internação, confirmaram SNU à esquerda. Um paciente morreu antes que os testes pudessem ser aplicados. Dos 30 pacientes que não cruzaram as pernas, os testes foram normais em 20. Dez pacientes apresentaram alterações mínimas, insuficientes para o diagnóstico de SNU. Conclusão : A perna direita cruzada sobre a esquerda pode representar um novo sinal semiológico associado à hemiplegia esquerda e SNU à esquerda.

Análise de modelos troposféricos no posicionamento baseado em redes usando o conceito de VRS

In the past few years several GPS (Global Position System) positioning techniques have been develope and/or improved with the goal of obtaining high accuracy and productivity in real time. The reference station network concept besides to enabling quality and reliability in positioning for scientific and civil GPS community, allows studies concerning tropospheric refraction modeling in the network region. Moreover, among the network corrections transmission methods available to users, there is the VRS (Virtual Reference Station) concept. In this method, the data of a virtual station are generated near the rover receiver (user). This provides a short baseline and the user has the possibility of using a single frequency receiver to accomplish the relative positioning. In this paper, the methodology applied to generate VRS data, using different tropospheric models is described. Thus, comparative tests were conducted in the four seasons with the NWP/INPE (Numerical Weather Prediction/National Institute for Space Research) and Hopfield tropospheric models. In order to analyse the VRS data quality, it was used the Precise Point Positioning (PPP) method, where satisfactory results were found. Mean differences between PNT/INPE and Hopfield models of 9.75% and 24.2% for the hydrostatic and wet days, respectively were obtained.

The impact of the law 10,267/2001 in the brazilian rural registration

The publication of the Law 10,267 of 08/28/2001 changed the paradigm of rural registration in Brazil, because this law known as the Law of Georeferencing has created the National Registration of Rural Property, that unifies in a common basis different registrations present in several government agencies, such as the National Institute for Colonization and Agrarian Reform (INCRA), the Secretariat of Federal Revenue, the Brazilian Institute of Environment and Natural Resources, and the National Indian Foundation. Also, this new registration system has a graphical component which has not existed until such date, where the boundaries of rural property are georeferenced to the Brazilian Geodetic System. This new paradigm has resulted in a standardization of the survey and its representation of rural properties according to the Technical Standard for Georeferencing of Rural Properties, published by INCRA in compliance with the new legislation. Due to the georeferencing, the creation of a public GIS of free access on the Internet was possible. Among the difficulties found it may be observed the great Brazilian territory, the need for specialized professionals, and especially the certification process that INCRA has to perform for each georeferenced property. It is hoped that this last difficulty is solved with the implementation of the Land Management System that will allow automated and online certification, making the process more transparent, agile and fast.

Classificação de impressões digitais

The biometric characteristics have been used increasingly as a way to identify an individual, mainly for security reasons. Among them, the fingerprint is the most used biometric characteristic around the world, because it is relatively simple and very efficient. In this scene, there was a significant increase in the size of databases containing information on fingerprints, necessary to perform the recognition of a person. The task of classifying them beforehand has become extremely important as it reduces dramatically the size of the problem during a search, because it is not necessary to go through the whole database. Considering its importance, in the last thirty years, many techniques have been developed to try to increase the efficiency of the classification process. This project followed the rules-based approach and the Software Development Kit (SDK) VeriFinger 6.1 was used to assist in the detection of cores and deltas. Additionally, the classification was also implemented by means of directional map and the Poincar´e index. To make the experiments, the number four database from the National Institute of Standards and Technology (NIST) was used, which is a standard in this area

O número de técnicos e técnicas que comandam equipes masculinas e femininas

It is known that gymnastics and sports, for the most part, were made by men for men, and its practice was almost exclusively for males, especially until the First World War. Vestiges of this strong male influence in sports still remain to this day, especially in leadership positions. It is clear that most sports, both male and female, are mostly coached by men. Thus, this study aimed to examine, through quantiqualitative research, the number of women and men who lead male and female volleyball, basketball and soccer elite teams, participating in the most important national championships, and the number of men and women graduated in physical education courses in Brazil in order to check a possible relationship between the low number of women working as a coach and the percentage of women graduated in physical education. For the acquisition of data, Internet searches were made on the sites of confederations, leagues and sports leagues selected for the study, and on the site of the National Institute of Educational Studies Anísio Teixeira (INEP). It was identified that the total number of graduates from 1995 to 2008 was 192,707, with 99,869 men and 92,838 women, showing a balance between these numbers, which did not happen with the numbers of male and female coaches. The data indicated that no women worked as a coach in male and female volleyball teams in the seasons 2006 to 2010, no woman worked as a coach in the male basketball teams in the seasons from 2000 to 2010, and only an average of 1.67 women led female basketball teams in the seasons 1998 to 2010, and no woman has ever worked as a coach for male soccer teams, while only an average of 2.67 women acted as a coach of female soccer teams. The difference between the number of men and women graduated in physical education is small and does not justify the low ...(Complete abstract click electronic access below)

Desenvolvimento de metodologias analíticas para determinação de selênio, cobre e manganês por GFAAS em amostras de vegetais de cultura orgânica e convencional utilizando extração por ultra-som

No presente trabalho é proposto um método para determinação de cobre, manganês e selênio em amostras de vegetais de cultura orgânica e convencional utilizando ultra-som no processo de extração dos analitos e posterior quantificação por espectrometria de absorção atômica em forno de grafite (GFAAS). Utilizando como solução extratora HCl 0,10 mol L-1, as condições ótimas de extração estabelecidas foram: massa de amostra de 100 mg; granulometria da amostra < 60 m; tempo de sonificação de cinco ciclos de 40 s e potência de sonificação de 136 W. As determinações dos analitos por GFAAS foram feitas utilizando-se temperaturas de secagem de 90-250 oC, temperatura de pirólise de 1300 oC, temperatura de atomização de 2300 oC e temperatura de limpeza de 2800 oC. Foi utilizado como modificador químico nitrato de paládio co-injetado junto com as amostras e tungstênio como modificador permanente. A exatidão e precisão do método de extração proposto foram avaliadas utilizando-se padrão certificado Corn Bran, RM 8433 – National Institute of Standards and Technology. Os resultados obtidos pelo método de extração por ultra-som mostraram-se equivalentes aos obtidos pelo método utilizando-se mineralização ácida das amostras em forno de microondas. No entanto, a metodologia proposta diminui consideravelmente o tempo de análise, o que favorece a velocidade analítica. Além disso, a quantidade de resíduos gerados para o ambiente também é bastante minimizada

Braquiterapia com sementes de iodo-125: manufatura e tratamento

According to the National Institute of Cancer – INCA, 466.730 new cancer cases will occur in Brazil in 2009. Prostate and Lung cancer in man are the most incident types (in exception of the non-melanoma cancer). The brachytherapy with 125-iodine sources is an important method of prostate cancer treatment. The implant with iodine-125 seeds uses aproximately 100 seeds that are imported impossibilitating the treatment in large scale. For this reason, a multidisciplinary group was created at the Energetic and Nuclear Research Institute – Radiation Technology Center (IPEN –CTR / SP) to develop a national 125-iodine source and established a facility for local production. The seeds manufacture in Brazil will diminish the cost of treatment and prostate brachytherapy will be offered to more patients. This work aim is to observe and discuss the methods used in seeds manufacture there are being developed in Brazil and to present an prostate cancer case folloied in A.C. Camargo Hospital. The 125-iodine is adsorbed in an silver wire, then deposited at titanium coat. The weld is made by an process of plasm sealing. The seeds goes through several test to guarantee that there is no leakage. The result is an high quality and cheaper product. The implant tecnique is an fast and save procedure. The medical physicst preplan the case to stipulate the quantity of seeds there will be used. At the dat of the implant the medical physicst replan the procedure due to changes of volume in the organ. That assure the correct dose distribution in the target. Besides, the 125-iodine low energy is absorbed at the volume of interrest saving sourronding healthy tissues such as the rectum and the urethra
