Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Messtechnische und energetische Validierung des BMVBS-Effizienzhaus Plus in Berlin - Messperiode März 2012 bis Februar 2013

In Berlin, the German Federal Ministry of Transport, Building and Urban Development (BMVBS) had a model building erected to pilot the new funding initiative 'Efficiency House Plus'. This model is also intended to test and prove the performance of various components of the concept and to provide experience for a wider application. During a 2-year monitoring programme conducted by Fraunhofer IBP, data of the occupied building will be measured and analysed with regard to its energy performance. This report presents the first preliminary results obtained from a 12-month survey period. Measurements found that - despite unfavourable meteorological boundary conditions - the power yields from façade-integrated PV systems still exceeded the energy needs of building services and building users during the survey period. The resultant surplus energy was used to cover about 25 % of the energy demand for electro-mobility. Under 'regular' weather conditions the House would have been able to completely cover the energy demand of the electric vehicles, and still there would have been energy left to be fed into the public grid. The meteorological boundary conditions that were prevailing in the measurement period from March 2012 through February 2013 caused a 20 % drop (3,320 kWh) in the solar power yield due to an actual reduction of the sunshine hours, which were about 40 % less than the annual average of the last ten years. In the survey period, the energy consumption in the building was about 75 % higher than predicted. This discrepancy was mainly due to the inefficient performance of the heating system (caused by substantially higher system temperatures than assumed). It was further due to the uncontrolled amount of outdoor air in the mechanical ventilation system and last but not least it was also due to the fact that the electricity consumption of household appliances was higher than expected. The results of the first year of operation suggest that in the case of high-performance buildings it is absolutely required to include a planned monitoring and regulation/control phase, to be capable of realising the design parameters in practice

Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8 TeV

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel

Transverse momentum and pseudorapidity distributions of charged hadrons in pp collisions at (s)\sqrt(s) = 0.9 and 2.36 TeV

Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at sqrt(s) = 0.9 and 2.36 TeV. The data were collected with the CMS detector during the LHC commissioning in December 2009. For non-single-diffractive interactions, the average charged-hadron transverse momentum is measured to be 0.46 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 0.9 TeV and 0.50 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 2.36 TeV, for pseudorapidities between -2.4 and +2.4. At these energies, the measured pseudorapidity densities in the central region, dN(charged)/d(eta) for |eta| < 0.5, are 3.48 +/- 0.02 (stat.) +/- 0.13 (syst.) and 4.47 +/- 0.04 (stat.) +/- 0.16 (syst.), respectively. The results at 0.9 TeV are in agreement with previous measurements and confirm the expectation of near equal hadron production in p-pbar and pp collisions. The results at 2.36 TeV represent the highest-energy measurements at a particle collider to date
