MÚSICA AFRO-BRASILEIRA: IDENTIDADE E CULTURA PARA A ESCOLA DA COMUNIDADE QUILOMBOLA DO CASTAINHO-PE

No agreste de Pernambuco verifica-se ações de construção da identidade nacional a partir de experiências culturais de tradição oral. A escola emerge neste contexto como palco de reavivamento e continuidade de valores identitários locais supostamente ameaçados por tendências de fluidez identitária decorrentes da globalização. A música, enquanto recurso didático e interativo social, emergiu nestes espaços locais da comunidade quilombola Castainho com o intuito de auxiliar uma ação de continuidade da tradição da própria comunidade no cotidiano expressivo dos mais jovens. Como fruto da observação etnográfica realizada no terreno emergiram dados e testemunhos locais acerca de intervenções diversas na escola Virgília Garcia Bessa, revelando que a escola cumpre para esta comunidade uma função integradora entre o passado e o presente. Este trabalho busca mostrar a importância de valorizar a cultura afrodescendente e que esta pode ser efetuada através da música, que é um elemento importante na construção da identidade cultural, nesse caso direcionada à cultura quilombola dos discentes da escola do Castainho que tem sido perdida com o decorrer dos anos e a interferência de culturas externas.

Strategic Management in Public Administration: A Balanced Scorecard Applicability Framework in School Management

Purpose - This study aims at developing a framework of the Balanced Scorecard (BSC) in public educational organizations.Theoretical framework – There are 3-sections: Strategic planning in public sector, Balanced Scorecard and BSC in the public sector. Strategic management in public administration is an important issue, with the BSC as one of the most widely used tools. Although, the application of this technique in public schools is still unexplored and uncommon, it does possess the potential to improve their effectiveness.Methodology - A 3-stage qualitative approach: (i) 8 semi-structured interviews with the principals of participating schools; (ii) 4 stages of focus groups with 3 of the principals from different schools; and (iii) non-participant observation using a field diary. Also, the data were analyzed through content analysis and cross-referencing the different forms of data collected.Findings - The results do not indicate a vast knowledge concerning the BSC’s techniques and tools, or an alignment between management planning posture, principles nor objectives of BSC application. Also, school planning is realized through the expertise of the Principal, without instruments of strategic management. Finally, adapted BSC models and strategic maps were proposed in public schools to collaborate and facilitate the strategic management process.Research, Practical & Social implications - The paper contributes towards developing new research agendas for strategic management in Brazil, with the possibility of improving public results and to appoint new practices in public schools.Originality/value - We have collaborated with the creation of a tool to use in the strategic planning of primary schools and pushing BSC studies into public sectors

Single Er3+, Yb3+: KGd3F10 Nanoparticles for Nanothermometry

Among several optical non-contact thermometry methods, luminescence thermometry is the most versatile approach. Lanthanide-based luminescence nanothermometers may exploit not only downshifting, but also upconversion (UC) mechanisms. UC-based nanothermometers are interesting for biological applications: they efficiently convert near-infrared radiation to visible light, allowing local temperatures to be determined through spectroscopic investigation. Here, we have synthesized highly crystalline Er3+, Yb3+ co-doped upconverting KGd3F10 nanoparticles (NPs) by the EDTA-assisted hydrothermal method. We characterized the structure and morphology of the obtained NPs by transmission electron microscopy, X-ray diffraction, Raman spectroscopy, and dynamic light scattering. Nonlinear spectroscopic studies with the Er3+, Yb3+: KGd3F10 powder showed intense green and red emissions under excitation at 980 and 1,550 nm. Two- and three-photon processes were attributed to the UC mechanisms under excitation at 980 and 1,550 nm. Strong NIR emission centered at 1,530 nm occurred under low 980-nm power densities. Single NPs presented strong green and red emissions under continuous wave excitation at 975.5 nm, so we evaluated their use as primary nanothermometers by employing the Luminescence Intensity Ratio technique. We determined the temperature felt by the dried NPs by integrating the intensity ratio between the thermally coupled H-2(11/2)-> I-4(15/2) and S-4(3/2)-> I-4(15/2) levels of Er3+ ions in the colloidal phase and at the single NP level. The best thermal sensitivity of a single Er3+, Yb3+: KGd3F10 NP was 1.17% at the single NP level for the dry state at 300 K, indicating potential application of this material as accurate nanothermometer in the thermal range of biological interest. To the best of our knowledge, this is the first promising thermometry based on single KGd3F10 particles, with potential use as biomarkers in the NIR-II region

Immediate and long-term evolution assessment after surgery on the saphenous vein with the modified CHIVA technique

Introduction The preservation of the great saphenous vein (GSV) has increasingly been considered when surgery for the treatment of varicose veins is indicated when complications from degenerative diseases, such as atherosclerosis at a coronary level and peripheral venous insufficiency occur. Thus, the autologous GSV is considered the best substitute for arterial revascularization. The technique that preserves the great saphenous vein is the Conservative Ambulatory Hemodynamic Management of Varicose Veins (CHIVA), which is widely used. Considering the importance and the use of this technique, the objective of this study was to evaluate the immediate and long-term evolution after surgery on the saphenous vein with the modified CHIVA technique. Materials and Methods A prospective observational study with data from individuals who underwent surgery for the preservation of the GSV by the modified CHIVA technique with the removal of varicose tributaries without ligation of the saphenofemoral junction. Data collection was performed from March 2014 to January 2015 at Padre Anchieta Hospital in Sao Bernardo do Campo, São Paulo. The variables were the great saphenous vein patency assessed by means of vein diameter, as described above, and the presence or not of reflux during the preoperative assessment, on the 30th day after surgery, and at the sixth month after surgery.Results The main results showed that there were no statistically significant differences in the saphenous vein diameter in any of the evaluated segments and in regard to the presence of reflux when comparing the pre-operative period to 30 days after CHIVA and to six months after CHIVA.Conclusion This study did not show change in the diameter of the veins, nor recurrence of reflux in the lower limbs, thus, it showed good results in the short, medium, and long term. There was no relationship between the diameter reductions of veins during the follow-up period. 

Concentração plasmática de glutamina e glutamato em ciclistas de elite durante duas temporadas de treinamentos e competições

It is well known that athletes practicing exhaustive exercise may present, at the end of a competitive season, signs of “overtraining”/”overreaching”, that comprise loss of performance and many physiological, metabolic and psychological changes. In an attempt to identify possible signs of “overreaching” we studied a group of ten professional cyclists, mass 72.1 ± 3.5 kg, VO2 máx 73.96 ± 3.7 mL.kg-1.min-1, age 23 ± 4.01 yr, for 2 consecutive competitive seasons. The maximal consumption of oxygen and blood lactate concentration, during an maximal incremental test, as a mean to evaluate changes in athletes performance, and plasma cortisol, glutamine and glutamate concentrations, as metabolic markers for “overreaching” were assessed. Blood samples were collected from the antecubital vein 9 times during the two years period, after bouts of high intensity training and competition. The maximal consumption of oxygen (74.9 ± 1.69 mL.kg-1.min-1 and 77.62 ± 3.37 mL.kg-1.min-1, beginning and the end of first season) and plasma lactate concentration did not change during the experiment, but at the end of both seasons the athletes reported early fatigue symptoms, evaluated by using Borg scale, and could not reach the same load at the end of the tests (early exhaustion). Plasma glutamine (559.8 µmo.l-1 to 531.7 µmo.l-1 in the first season and 438.7 µmo.l-1 to 393.06 µmo.l-1 in the second season) and glutamate (214 µmo.l-1 to 167.2 µmo.l-1 in the first season and 244.2 µmo.l-1 to 205.64 µmo.l-1 in the second season) concentration were reduced at the end of both seasons, and plasma cortisol (363.15 µmo.l-1 to 569.66 µmo.l-1 in the second season), increased. Therefore, we conclude that the changes in plasma glutamine, glutamate and cortisol during a competitive season could be used as an early indicative of “overreaching”.É bem descrito que atletas que praticam atividade física exaustivas podem apresentar, ao final de um macrociclo de competições, sinais de “overtraining”/”overreaching” que incluem a diminuição no desempenho e muitas mudanças fisiológicas, metabólicas e psicológicas. Na tentativa de identificar possíveis sinais do “overreaching”, nós estudamos um grupo de 10 ciclistas profissionais, peso 72,1 ± 3,5 kg, consumo máximo de oxigênio (VO2 máx) 73,96 ± 3,7 mL.kg-1.min-1, idade 23 ± 4,01 anos, durante dois macrociclos anuais consecutivos. O VO2 máx e a concentração sangüínea de lactato, durante um teste incremental máximo, foram utilizados para avaliar o desempenho dos atletas e a concentração plasmática de cortisol, glutamina e glutamato, como marcadores metabólicos do “overreaching”. Durante o período de dois anos, nove amostras de sangue foram coletadas por punção venosa após os períodos de treinamento de alta intensidade e de competições. O VO² máx (74,9 ± 1,69 mL.kg-1.min-1 e 77,62 ± 3,37 mL.kg-1.min-1, respectivamente início e final do primeiro macrociclo) e a concentração plasmática de lactato não tiveram alterações durante o estudo, contudo, ao final de ambos macrociclos, os atletas apresentaram sinais de fadiga, percebidos através da escala de esforço subjetivo de Borg e pelo fato de não conseguirem suportar as mesmas cargas ao final dos testes (exaustão precoce). A concentração plasmática de glutamina (559,8 µmo.l-1 para 531,7 µmo.l-1 no primeiro macrociclo e 438,7 µmo.l-1 para 393,06 µmo.l-1 no segundo macrociclo) e do glutamato (214 µmo.l-1 para 167,2 µmo.l-1 no primeiro macrociclo e 244,2 µmo.l-1 para 205,64 µmo.l-1 no segundo macrociclo) diminuíram e a concentração plasmática de cortisol (363,15 µmo.l-1 para 569,66 µmo.l-1 no segundo macrociclo) aumentou. Com isso, nós concluímos que durante um macrociclo competitivo as mudanças na concentração plasmática de glutamina, glutamato e cortisol, podem ser utilizadas como marcadores precoces de um estágio de “overreaching”

ATRIBUTOS FÍSICOS, MINERALOGIA E COMPACTAÇÃO DO SOLO EM AMBIENTES NATURAIS NO EXTREMO NORTE DA AMAZÔNIA, BRASIL

RESUMO: Os solos da Amazônia em sua grande maioria são caracterizados como de baixa fertilidade natural, baixa saturação por bases, e elevada saturação por alumínio, embora apresentem boas características morfológicas e físicas, sabe-se que os ecossistemas naturais apresentam integração harmoniosa entre a cobertura vegetal e os atributos do solo, decorrente de processos essenciais de ciclagem de nutrientes e acumulação e decomposição da matéria orgânica. O presente trabalho teve como objetivo avaliar os atributos físicos, mineralogia e compactação de solos em ambientes naturais em Boa Vista, Roraima. Em cada ponto amostral das respectivas áreas em estudo, foram coletadas amostras na forma de torrão e anéis volumétricos para determinação de atributos do solo. A resistência do solo a penetração foi determinada por medidor eletrônico de compactação de solo marca FALKER PLG1020. A mineralogia das frações areia, silte e argila foram determinadas por difratometria de raios-X, de acordo com Whittig; Allardice (1986). Os maiores valores de compactação foram observados na área de savana. Os solos das áreas de savana e floresta foram classificados em textura argilosa e franco-argilo-arenosa, respectivamente. A caulinita foi predominante na composição da argila dos solos estudados, o alto grau de intemperismo associado a composição mineralógica mostra indícios de baixa fertilidade desses solos, outros minerais comuns (goethita, hematira e gibsita) foram poucos expressivos nos ambientes estudados. Palavras-chave: Solos amazônicos, atributos físicos, mineralogia.         PHYSICAL ATTRIBUTES, MINERALOGY AND SOIL COMPACTION IN NATURAL ENVIRONMENTS IN THE NORTHERN AMAZON, BRAZIL ABSTRACT: Most Amazonian soils are characterized by low natural fertility, low base saturation, and high aluminum saturation. Although they have good morphological and physical characteristics, it is known that natural ecosystems have a harmonious integration between cover. and soil attributes, resulting from essential processes of nutrient cycling and accumulation and decomposition of organic matter. The present work aimed to evaluate the physical attributes, mineralogy and soil compaction in natural environments in Boa Vista, Roraima. At each sampling point of the respective areas under study, samples were collected in the form of clod and volumetric rings to determine soil attributes. The penetration resistance of the soil was determined by a FALKER PLG1020 electronic soil compaction meter. The mineralogy of sand, silt and clay fractions were determined by X-ray diffraction. The highest compaction values were observed in the savannah area. The soils of the savannah and forest areas were classified in clayey and sandy loamy texture, respectively. The kaolinite was predominant in the clay composition of the studied soils, the high degree of weathering associated with mineralogical composition shows signs of low fertility of these soils, other common minerals (goethite, hematite and gibbsite) were few expressive in the studied environments.

Este trabalho objetivou analisar a percepção dos enfermeiros frente à assistência de enfermagem às mães de filho natimorto. Assim como descrever e compreender as emoções que emergem diante da assistência de enfermagem às mães enlutadas; verificando se os enfermeiros se percebem preparados para lidar com os processos de perda diante do óbito. A pesquisa foi realizada em uma maternidade pública de Manaus/Amazonas no Instituto da Mulher Dona Lindú, com enfermeiras atuantes e efetivas na instituição, através do método fenomenológico de pesquisa de Giorgi e Sousa (2010). O fenômeno foi distribuído em quatro categorias: Necessidade de ajuda; Prática do exercício humano; Visão de morte e Culpabilização, para clarificar a análise e discussão. De forma geral as enfermeiras descreveram suas percepções frente à assistência às mães de filho natimorto, como sendo uma assistência extremamente difícil e conflituosa. Observou-se que as emoções que emergiram diante da assistência de enfermagem às mães de filho natimorto faziam com que as enfermeiras revivessem perdas pessoais e que sentissem-se tocadas com a situação vivenciada pelas mães, refletindo em um sentimento de empatia com as mesmas e até de uma projeção para o lugar delas, emergiram sentimentos de tristeza, dor que toca, comoção, choro e melancolia

Purification of a lectin with antibacterial activity from Bothrops leucurus snake venom

A novel lectin was isolated from Bothrops leucurus snake venom using a combination of affinity and gel filtration chromatographies. the lectin (BIL) agglutinated glutaraldehyde-treated rabbit and human erythrocytes with preference for rabbit erythrocytes. Galactose, raffinose, lactose, fetal bovine serum and casein inhibited lectin-induced rabbit erythrocyte agglutination. BIL, with a molecular mass of 30 kDa and composed of two subunits of 15 kDa, showed dependence on calcium. BIL is an acidic protein with highest activity over the pH range of 4.0-7.0 and stable under heating to 70 degrees C. Fluorescence emission spectra showed tryptophan residues partially buried within the lectin structure. the percentages of secondary structure revealed by circular dichroism were 1% alpha-helix, 44% beta-sheet, 24% beta-turn and 31% unordered. BIL showed effective antibacterial activity against Gram-positive bacteria Staphylococcus aureus, Enterococcus faecalis and Bacillus subtilis with minimal inhibitory concentrations of 31.25, 62.25 and 125 mu g/mL, respectively. in conclusion, B. leucurus snake venom contains a galactoside-binding lectin with antibacterial activity.
