Caracterização morfológica dos acessos de feijão comum (Phaseolus vulgaris).

A diversidade genética é a responsável por essa segurança e estabilidade de produção. A coleta, caracterização e manutenção desses acessos disponibilizará aos programas de melhoramento genes responsáveis por características desejáveis na obtenção de novas cultivares.Apresentação oral - graduação

Young peoples’ reflections on what teachers think about family obligations that conflict with school: A focus on the non-normative roles of young caring and language brokering

In “Western” contexts school attendance is central for an ‘ideal’ childhood. However, many young people engage with home roles that conflict with school expectations. This paper explores perceptions of that process in relation two home activities - language brokering and young caring. We interviewed 46 young people and asked them to reflect on what the teacher would think when a child had to miss school to help a family member. This paper discusses the young people’s overall need to keep their out-of-school lives private from their teachers

Diário de campo: ferramenta para desenvolver o hábito de registrar procedimentos na produção integrada de morango.

Segundo as Normas Técnicas Gerais para a Produção Integrada de Frutas (NTGPIF), descritas no Marco Legal da Produção Integrada de Frutas (PIF) do Brasil, é obrigatório o registro de dados da cultura necessários à adequada gestão da PIF. A elaboração de cadernos de campo e de pós-colheita, atualizados e fiéis à realidade, é necessária para garantir a rastreabilidade (ANDRIGUETO; KOSOSKI, 2002). Assim sendo, rastreabilidade e cadernos de campo e de pós-colheita são pressupostos também para a adoção da Produção Integrada de Morango (PIMo) (ANTUNES et al., 2007). A fim de cumprir com os preceitos da NTGPIF, porém, em função da heterogeneidade de níveis técnicos entre produtores, bem como da falta de costume em registrar procedimentos realizados no campo, o grupo da PIMo de Atibaia, Jarinu e Região propôs, de forma participativa, a elaboração de um sistema simplificado de anotações. O objetivo deste trabalho é apresentar um sistema simplificado de registros como alternativa para iniciar a anotação de procedimentos em uma lavoura de morangos onde essa prática ainda não tenha sido incorporada

Viabilidade de sementes de feijão comum do Banco Ativo de Germoplasma da Embrapa Arroz e Feijão.

O Banco Ativo de Germoplasma (BAG) da Embrapa Arroz e Feijão possui 15.720 acessos de feijão, sendo a maioria deles acessos de feijão comum (Phaseolus vulgaris). Em 2009, foi iniciada uma reestruturação física, que incluía o inventário de todo acervo. O objetivo desse estudo foi avaliar a viabilidade de parte dos acessos de feijão comum do BAG.Pôster - graduação

Nesting Induced Precursor Effects: a Renormalization Group Approach

We develop a controlled weak coupling renormalization group (RG) approach to itinerant electrons. Within this formalism we rederive the phase diagram for two-dimensional (2D) non-nested systems. Then we study how nesting modifies this phase diagram. We show that competition between p-p and p-h channels, leads to the manifestation of unstable precursor fixed points in the RG flow. This effect should be experimentally measurable, and may be relevant for an explanation of pseudogaps in the high temperature superconductors (HTC), as a crossover phenomenon.Comment: 4 pages, 4 figures, 1 tabl

New remarks on the linear constraint self-dual boson and Wess-Zumino terms

In this work we prove in a precise way that the soldering formalism can be applied to the Srivastava chiral boson (SCB), in contradiction with some results appearing in the literature. We have promoted a canonical transformation that shows directly that the SCB is composed of two Floreanini-Jackiw's particles with the same chirality which spectrum is a vacuum-like one. As another conflictive result we have proved that a Wess-Zumino term used in the literature consists of the scalar field, once again denying the assertion that the WZ term adds a new degree of freedom to the SCB theory in order to modify the physics of the system.Comment: 6 pages, Revtex.

Implications of mitotic and meiotic irregularities in common beans (Phaseolus vulgaris L.).

The common bean has great social and economic importance in Brazil and is the subject of a high number of publications, especially in the fields of genetics and breeding. Breeding programs aim to increase grain yield; however, mitosis and meiosis represent under explored research areas that have a direct impact on grain yield. Therefore, the study of cell division could be another tool available to bean geneticists and breeders. The aim of this study was to investigate irregularities occurring during the cell cycle and meiosis in common bean. The common bean cultivar used was BRSMG Talismã, which owing to its high yield and grain quality is recommended for cultivation in Brazil. We classified the interphase nuclei, estimated the mitotic and meiotic index, grain pollen viability, and percentage of abnormalities in both processes. The mitotic index was 4.1%, the interphase nucleus was non-reticulated, and 19% of dividing somatic cells showed abnormal behavior. Meiosis also presented irregularities resulting in a meiotic index of 44.6%. Viability of pollen grains was 94.3%. These results indicate that the common bean cultivar BRSMG Talismã possesses repair mechanisms that compensate for changes by producing a large number of pollen grains. Another important strategy adopted by bean plants to ensure stability is the elimination of abnormal cells by apoptosis. As the common bean cultivar BRSMG Talismã is recommended for cultivation because of its good agronomic performance, it can be concluded that mitotic and meiotic irregularities have no negative influence on its grain quality and yield
