Formar um bom professor não é uma tarefasimples, pois existem conceitos e até metodologias que nem sempre conseguimos trabalhar em sala de aula ou nos estágios supervisionados. São conceitos que estão mais voltados para a formação humana do que para a formaçãoacadêmica. Mesmo após o estágio supervisionado, muitas vezes o novo professor não é capaz de ser um gestor social, seja em uma situação de conflito ou em uma situação no processo ensino-aprendizagem. Além disso, os professores no ensino médio nem sempre dispõe de tempo necessário com os alunos para conseguir um melhor aproveitamento acadêmico da turma. Neste trabalho, iremos mostrar como a aproximação entrelicenciandos em física e alunos do ensino médio pode render bons frutos para ambos, num processo que aqui denominamosde «cross-fertilisation»

Semi-field assessment of the BG-Malaria trap for monitoring the African malaria vector, Anopheles arabiensis

Odour-baited technologies are increasingly considered for effective monitoring of mosquito populations and for the evaluation of vector control interventions. The BG-Malaria trap (BGM), which is an upside-down variant of the widely used BG-Sentinel trap (BGS), has been demonstrated to be effective to sample the Brazilian malaria vector, Anopheles darlingi. We evaluated the BGM as an improved method for sampling the African malaria vectors, Anopheles arabiensis. Experiments were conducted inside a large semi-field cage to compare trapping efficiencies of BGM and BGS traps, both baited with the synthetic attractant, Ifakara blend, supplemented with CO2. We then compared BGMs baited with either of four synthetic mosquito lures, Ifakara blend, Mbita blend, BG-lure or CO2, and an unbaited BGM. Lastly, we compared BGMs baited with the Ifakara blend dispensed via either nylon strips, BG cartridges (attractant-infused microcapsules encased in cylindrical plastic cartridge) or BG sachets (attractant-infused microcapsules encased in plastic sachets). All tests were conducted between 6P.M. and 7A.M., with 200–600 laboratory-reared An. arabiensis released nightly in the test chamber. The median number of An. arabiensis caught by the BGM per night was 83, IQR:(73.5–97.75), demonstrating clear superiority over BGS (median catch = 32.5 (25.25–37.5)). Compared to unbaited controls, BGMs baited with Mbita blend caught most mosquitoes (45 (29.5–70.25)), followed by BGMs baited with CO2 (42.5 (27.5–64)), Ifakara blend (31 (9.25–41.25)) and BG lure (16 (4–22)). BGM caught 51 (29.5–72.25) mosquitoes/night, when the attractants were dispensed using BG-Cartridges, compared to BG-Sachet (29.5 (24.75–40.5)), and nylon strips (27 (19.25–38.25)), in all cases being significantly superior to unbaited controls (p < 000.1). The findings demonstrate potential of the BGM as a sampling tool for African malaria vectors over the standard BGS trap. Its efficacy can be optimized by selecting appropriate odour baits and odour-dispensing systems

The monoclinic phase of PZT ceramics: Raman and phenomenological theory studies

This work reports on the first Raman detection of the tetragonal to monoclinic phase transition in PZT ceramics near morphotropic phase boundary at low temperatures. The transition is characterized by changes in the frequency of lattice modes with the temperature. The results presented here confirm the previous one recently reported by Noheda et al. using high-resolution synchrotron X-ray powder diffraction technique and dielectric measurements. The stability of the new phase is discussed within the framework of phenomenological Landau-Devonshire Theory.Comment: 6 pages including 4 figures, Latex, submitted to Applied Physics Letter

Observations on non-randomly distribution of spores of Henneguya spp. (Cnidaria, Myxosporea, Myxobolidae) within plasmodia

Species of the cnidarian genus Henneguya Thelohan, 1892 (Myxosporea: Myxobolidae) are histozoic parasites commonly found in freshwater and, more rarely, in marine fish. The development of these parasites in fish tissues includes the formation of plasmodia within which occurs the sporogony originating spores with two caudal processes, which are usually randomly distributed within the plasmodia. In this report the authors present some cases of non-random distribution of the spores of six species of Henneguya within their plasmodia. Two different patterns of non-random distribution were found based on a literature survey. These patterns and their origin are discussed. Apparently this non-random distribution of the spores is due to both internal and external factors.European Regional Development Fund (ERDF) through the COMPETE - Operational Competitiveness Programmenational funds through FCT - Foundation for Science and TechnologyCNPqGINOPUniv Porto, Fac Ciencias, Dept Biol, Rua Campo Alegre,Edificio FC4, P-4169007 Oporto, PortugalCIMAR, CIIMAR, Ctr Interdisciplinar Invest Marinha & Ambiental, Matosinhos, PortugalInst Super Engn Porto, Lab Engn Matemat LEMA, Oporto, Portugal|Univ Fed Sao Paulo, UNIFESP, Dept Ecol & Biol Evolut, Diadema, SP, BrazilUniv Estadual Campinas, Inst Biol, Dept Biol Anim, Campinas, SP, BrazilCtr Agr Res, Inst Vet Med Res, Budapest, HungaryHungarian Acad Sci MTA, Budapest, HungaryUniv Fed Sao Paulo, UNIFESP, Dept Ecol & Biol Evolut, Diadema, SP, BrazilEuropean Regional Development Fund (ERDF) through the COMPETE - Operational Competitiveness Programmenational funds through FCT - Foundation for Science and Technology: PEst-C/MAR/LA0015/2013CNPq: 305630/2013-0GINOP: 2.3.3-15-2016-00004Web of Scienc
