Resumo: O processo de formação continuada de professores é fundamental para a efetivação de um currículo que seja adequado às realidades locais e regionais, dessa forma, o projeto de extensão promovido pelo IFPR -Campus Paranaguá -em 2012 e 2014 teve como objetivo a oferta de oficinas para promover a formação continuada dos professores de Ciências e Biologia da rede pública de ensino do estado do Paraná do Núcleo Regional de Paranaguá, a partir da experiência dos docentes e estudantes do Campus Paranaguá do IFPR. Para isso, foram ofertadas duas oficinas para professores dos diferentes municípios do litoral do Paraná, sendo uma de Ciência no Cinema e outra de Experimentação em Ciências. As inscrições e participações foram oportunizadas pelo Núcleo Regional de Educação do Paraná -Paranaguá (NRE). Com o relato desta experiência de extensão foi possível perceber que o projeto oportunizou o intercâmbio de práticas e conhecimentos entre os professores da rede pública. Além disso, foi possível diagnosticar a carência de oferta desses cursos de formação continuada na região litorânea do Paraná e o potencial de mudança de práticas pedagógicas de acordo com as realidades locais no litoral do Paraná. Palavras-chave:Abstract: The process of continuous teacher training is fundamental to the realization of a curriculum that is appropriate to local and regional realities. In this way, the extension project promoted by IFPR Campus Paranaguá in 2012 and 2014 had the objective of offering workshops to promote the continuing education of Science and Biology teachers in the Paraná state public school of the Paranaguá Regional Nucleus, based on the experience of the teachers and students of the Campus Paranaguá of the IFPR. For this, two workshops were offered for teachers from the different municipalities of the coast of Paraná, one of Science in Cinema and another one of Experimentation in Sciences. The registrations and participation were given by the Regional Education Center of Paraná -Paranaguá (NRE). With the report of this experience of extension it was possible to perceive that the project facilitated the exchange of practices and knowledge among the teachers of the public network. In addition, it is possible to diagnose the lack of supply of these continuing education courses in the coastal region of Paraná and the potential of changing pedagogical practices according to the local realities in the coast of Paraná.

Background In the last two decades, molecular markers have been used as an additional tool to characterize and identify cactus species of the Cereus genus. The hypothesis in the present study is that inter simple sequence repeats of DNA (ISSR) may contribute to reveal the molecular divergence at DNA level between Cereus plants from different Brazilian biomes. Methods and Results Polymorphisms in ISSRs were used as molecular markers to evaluate genetic diversity and divergence among Cereus plants in the Atlantic Forest, Pampa, Cerrado, Caatinga, Amazon Forest, and Pantanal biomes cultivated in in the south (S), southeast (SE), Midwest (MW), north (NO) and northeast (NE) of Brazil. The polymorphism rates were higher in plants from the S and the highest genetic divergences were observed between plants from MW and NE, S and MW and S and NE regions. Plants from the MW in the Pantanal biome were the most divergent. The 198 ISSR segments indicated occurrence of only a species of Cereus in the south. Conclusion ISSR markers showed high reproducibility, ease, and rapidity in carrying out the experiments and low cost compared to SSR markers and was useful to group plants of Cereus from the same biome and to discriminate plants from different biomes.

Neste artigo serão apresentados resultados da observação microscópica feita em vidros lascados, coletados no sítio arqueológico histórico Engenho do Murutucu, localizado no município de Belém, Estado do Pará. Além de passar por uma observação em microscópio, os exemplares arqueológicos foram comparados com peças produzidas após uma série experimental que perpassou três fases: fragmentação aleatória de garrafas, pisoteio, confecção e uso de instrumentos em dois substratos: madeira e couro. A comparação feita entre os materiais experimentais e arqueológicos, aliada a observação microscópica sugeriram que os vidros lascados do Murutucu tratam-se de instrumentos.
