CONSIDERAÇÕES SOBRE A EDUCAÇÃO ENERGÉTICA E O SEU TRAÇO TRANSDISCIPLINAR: UMA ANÁLISE DAS GRADES CURRICULARES DE INSTITUIÇÕES DE ENSINO SUPERIOR DE SANTA CATARINA

Enfatizando o traço transdisciplinar da educação energética, este estudo analisa as grades curriculares de instituições públicas e privadas de ensino superior do Estado de Santa Catarina. Dando seguimento a estudos anteriores, num primeiro momento foi realizada a coleta de dados, através de pesquisa na internet, das grades curriculares dos seguintes cursos: administração, ciências biológicas, ciências econômicas, direito, engenharia sanitária e ambiental, engenharia civil, engenharia elétrica e tecnólogo em gestão ambiental. Na sequência, por meio de pesquisa bibliográfica e análise conceitual a investigação procura evidenciar os traços de transdisciplinaridade contidos em propostas curriculares que privilegiam confluência entre distintos saberes, dando ênfase ao valor epistemológico e social da educação energética em diferentes cursos universitários. Gráficos, quadro e tabelas são apresentados ilustrando o espaço existente para se transitar pela diversidade dos conhecimentos, sem fronteiras epistemológicas rígidas, necessário ao planejamento energético. Observou-se que onde são ofertadas disciplinas de educação energética, há um percentual inferior a 2,5% da carga horária total dos cursos superiores, sendo este o espaço encontrado para a interação da transdisciplinaridade com a educação energética

Relationship among epidemiological parameters of six childhood infections in a non-immunized Brazilian community

Epidemiological parameters, such as age-dependent force of infection and average age at infection () were estimated for rubella, varicella, rotavirus A, respiratory syncytial virus, hepatitis A and parvovirus B19 infections for a non-immunized Brazilian community, using the same sera samples. The for the aforementioned diseases were 8.45 years (yr) [95% CI: (7.23, 9.48) yr], 3.90 yr [95% CI: (3.51, 4.28) yr], 1.03 yr [95% CI: (0.96, 1.09) yr], 1.58 yr [95% CI: (1.39, 1.79) yr], 7.17 yr [95% CI: (6.48, 7.80) yr] and 7.43 yr [95% CI: (5.68, 9.59) yr], respectively. The differences between average ages could be explained by factors such as differences in the effectiveness of the protection conferred to newborns by maternally derived antibodies, competition between virus species and age-dependent host susceptibility. Our seroprevalence data may illustrate a case of the above-mentioned mechanisms working together within the same populatio

Electroacupuncture and Moxibustion Decrease Renal Sympathetic Nerve Activity and Retard Progression of Renal Disease in Rats

Background/Aim: Chronic kidney disease (CKD) is an increasing major public health problem worldwide. the sympathetic nervous system and nitric oxide play an important role in the pathogenesis of CKD. Traditional Chinese medicine has accumulated thousands of years of therapeutic experiences. Electroacupuncture (EA) and moxibustion (MO) are two such therapeutic strategies. the aim of this study was to investigate the renal and hemodynamic effects of EA-MO in an experimental model of a CKD. Methods: Male Wistar rats submitted to 5/6th nephrectomy (5/6 NX) were studied for 8 weeks. There were four groups: (1) control, normal rats; (2) NX, 5/6 NX only; (3) NX-AS, 5/6 NX and EA-MO session using sham points, and (4) NX-AM, 5/6 NX and EA-MO session using real acupoints. Biochemical and blood pressure studies, renal sympathetic nerve activity measurements, nitric oxide levels and the histopathological indices were assessed. Results:The EA- and MO-treated group presented significant improvement in all measured functional and histopathological parameters. Conclusion: These findings suggest that EA-MO had beneficial effects on CKD. This effect was probably achieved by the modulation of the renal sympathetic nerve activity and nitric oxide levels, leading to decreased blood pressure, which is associated with less proteinuria.

Sistema fotovoltaico: fontes renováveis como elemento educacional no ensino de ciência / Photovoltaic system: renewable sources as an educational element in science education

O experimento foi desenvolvido com o objetivo de demostrar o funcionamento de sistemas fotovoltaicos e utilizá-lo como aparato experimental em aulas de ciências, eletricidade, sustentabilidade e conservação de energia. Para isso, construiu-se uma maquete de uma casa popular com suas luminárias e tomadas elétricas. O sistema projetado para a maquete contém cinco lâmpadas de LED com 7 watts cada e pode carregar até dois aparelhos celulares simultaneamente. A maquete foi confeccionada com material reciclável, numa base de madeira, paredes de papelão e dividida em cinco cômodos. E poderá ser apresentada em escolas, universidade e comunidade, como exemplo de fontes alternativas de energia renovável

Adaptable Ultraviolet Refl ecting Polymeric Multilayer Coatings of High Refractive Index Contrast

A synthetic route is demonstrated to build purely polymeric nanostructured multilayer coatings, adaptable to arbitrary surfaces, and capable of effi ciently blocking by refl ection a targeted and tunable ultraviolet (UV) range. Refl ection properties are determined by optical interference between UV light beams refl ected at the interfaces between polystyrene layers of different porosity and hence refractive index. As no dopant absorber intervenes in the shielding effect, polymer degradation effects are prevented. Alternated porosity results from the modulation of photochemical effects at the few tens of nanometers length scale, combined with the collective osmotic shock induced during the processing of the precursor diblock copolymer fi lm. Experimental evidence of the application of this method to coat rough surfaces with smooth and conformal UV protecting fi lms is providedEuropean Union’s Seventh Framework Programme 307081Ministerio de Economía y Competitividad MAT2011-2359
