Índices de emissão de ramos em pereiras.

A elaboração de escalas de emissão de ramos em pereiras objetiva classificar os genótipos quanto a seu hábito de crescimento, as quis serão úteis para compor o índice de vigor de plantas e para a seleção de genitores em programas de melhoramento genético. Para isso, foram desenvolvidas duas escalas: a primeira, para avaliar a quantidade de emissão de ramos secundários, ou seja, os ramos originados do tronco principal da planta, composta por três classes e com notas variando entre 1 e 5, contendo desenhos e exemplos de genótipos; a segunda, para avaliar o tipo e a quantidade de ramos terciários e quaternários emitidos a partir dos ramos secundários, sendo ela composta também por três classes e notas variando de 1 a 5. Utilizando as duas tabelas, foram avaliadas duas (em alguns casos somente uma) plantas/genótipo do Banco de Germoplasma de Pereira existente na Estação Experimental de Caçador, em Caçador, SC, no ano agrícola 2012/13. As plantas ficaram sem poda e condução durante 2 anos. Exemplos de genótipos com menor emissão de ramos secundários foram os cvs. Kousui, Kikusui, Nijisseiki, Beurre d?Anjou e Doyenne du Comice; e com maior emissão os cvs. Le Conte e Md. Siebold. Quanto à menor emissão de ramos terciários e quaternários, destacaram-se os cvs. Rugosa e Md. Siebold; e com maior emissão os cvs. Feliz e Choujuurou. As escalas foram eficientes na separação dos genótipos

Classes de vigor de plantas de genótipos de pereira.

O índice de vigor de pereiras pode ser utilizado como referência em trabalhos de melhoramento genético para a seleção de genitores e também como indicativo de manejo de plantas em pomares comerciais. Para isso, foi gerado um índice de vigor utilizando informações de emissão de ramos secundários (originados do tronco principal da planta), de ramos terciários e quaternários (gerados respectivamente dos ramos secundários e terciários), além da medida da altura da planta

Cross-cultural adaptation of the City Birth Trauma Scale for the Brazilian context

Background: Posttraumatic stress disorder consists of a set of symptoms that occurs in response to one or more traumatic events and can occur in postpartum, from traumatic situations related to the birth or to the baby’s health in the first days of life. It is important tracking the presence of birth trauma, but there is not available instruments in the Brazilian context for this purpose. Objectives: To present the cross-cultural adaptation of City Birth Trauma Scale (BiTS) into Brazilian portuguese. Methods: Cross-cultural adaptation involved independent translations, synthesis,back-translation, and submission to the original author’s appreciation. After the scale was subjected to face validity, followed by a pilot study with postpartum mothers. Results: All steps were performed for the cross-cultural adaptation. Regarding face validity, items evaluated concerning different types of equivalence, presented satisfactory agreement values (≥4.20). Most of the expert’s suggestions were followed, being the main ones related to adjustments in prepositions, pronouns and verbal subjects. Pilot study showed that the mothers had been able to understand and respond to the instrument without adjustments. Discussion: BiTS’s Brazilian version proved to be cross-culturally adapted, ensuring the possibility of intercultural data comparison from the semantic, idiomatic, cultural, and conceptual perspectives. New studies are being conducted to attest its psychometric adequac

Efeito das técnicas de fusão sobre a fluidez de ligas do sistema cobre-alumínio.

It was evaluated the castability of four copper-aluminium alloy according the melting casting method used. The specimens were made using polyester mesh screen, with 11 x 11 filaments of 0.26 mm thick, fixed along of two adjacent edges in wax bar, with the sprue attached at their junction. The alloys were in an electrical casting machine and a centrifugal casting machine with an air/gas torch. The castability values were obtained by the percentage of completed segments of the resulting cast alloy screen. It was verified that the use of the electrical casting machine produced higher castability values to the copper-aluminium alloys than those produced by a centrifugal casting machine with an air/gas torch

Rugosidade superficial de ligas com alto conteúdo de cobre, em função do aquecimento acima da temperatura de fusão.

Being the surface roughness a fundamental property in the fit of the castings, it was determined the roughness of 5 high-copper casting alloys, according to the heating over their melting temperature. That way, the specimens made with smooth plastic in the shape of a rectangular plate, 2 mm x 7 mm x 11 mm were invested into a cristobalite investment. After heating and elimination on the plastic, the molds were filled by 3 g of molten alloy, casted in a electrical casting machine at the casting temperature at 25 degrees C and 50 degrees C overheating. The surface roughness was measured in a roughness analyser, Talysurf. As a result, it was verified that there is a variation of surface roughness among the alloys tested, and the heating of the alloys until 50 degrees C over the melting temperature does not interfere in the roughness
