Como e por que trabalhar poesia na sala de aula é o que se pretende abordar neste trabalho. A sensibilização para a linguagem poética, suas características estruturais e um pequeno repertório teórico que sustenta a reflexão sobre o fazer poético vem sendo trabalhado ao longo da atividade acadêmica em forma de Oficinas de Leitura e Produção. Os grupos que vivenciaram a metodologia dessas oficinas são estudantes do Ensino Fundamental I e II, estagiários de Letras do Instituto de Aplicação da UERJ, profissionais de diferentes áreas da disciplina Oficina de Poesia do curso de Especialização em Literatura Infantil e Juvenil da UFF, além de professores que frequentaram minicursos em congressos da área. As oficinas de poesia têm se mostrado eficazes como possibilidade de aproximar do gênero lírico diferentes tipos e faixas etárias de leitores, permitindo-lhes manipular o estrato linguístico de forma criativa e, principalmente em relação aos professores da educação básica, vivenciar atividades que podem enriquecer a prática docente. Os resultados dessas oficinas podem ser mensurados pelo maior interesse dos estudantes em ler, compreender e produzir poemas e a participação entusiasmada dos professores que inseriram a metodologia da oficina em suas práticas docentes. O repertório ficcional é amplo e varia de acordo com o público participante e a experiência do leitor. Já o repertório teórico apoia-se principalmente em: CANDIDO (1986; 1989; 2004); CÍCERO (2007); SOARES (1989); CARA (1986); MORICONI (2002); MOISÉS (2012); SECCHIN (2018) dentre outros. Abstract This paper intends to address how and why to work with poetry in the classroom. Awareness of poetic language, its structural characteristic and a brief theoretical framework that give support to reflections on ways of doing poetry has been worked on throughout academic activity in the form of Reading and Production Workshops. Groups that have experienced the methodology of those workshops comprise students from primary and middle schools and undergraduate students of the Lyrics Course in the Institute of Application at UERJ as well as professionals from different areas of knowledge in the subject Poetry Workshop from the specialization course in Children and Youth Literature and teachers who attended mini courses in congress in the area. The poetry workshops have proved to be effective as a possibility to bring different types and age groups of readers closer to the lyric genre, allowing them to manipulate the linguistic stratum in a creative way, especially basic education teachers, who have the chance to experience activities that can improve teaching practice. The results of these workshops can be measured by students' greater interest in reading, understanding and producing poems and the enthusiastic participation of the teachers who adopted the workshop methodology in their teaching practices. The fictional repertoire is broad and varies according to the participating audience and reader's experience. The theoretical framework is based mainly on: CANDIDO (1986; 1989; 2004); CÍCERO (2007); SOARES (1989); CARA (1986); MORICONI (2002); MOISÉS (2012); SECCHIN (2018) among others.

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.
