Comparação entre valores de ensaios experimentais e calculados da resistência ao embutimento da madeira de Pinus taeda L.

To design connections between timber parts with metal dowels (nails or bolts), two phenomena must be considered: bending of the metal dowel and the embedment strength in the wood. The Brazilian Standard ABNT NBR 7190:1997 proposes the methods used in the laboratory tests to determine the embedment strength with the metal dowell and, in the absence of testing, specifies relations to calculate the embedment strength from the compression strength. The aim of this research was to compare the embedment strength values obtained by experimental tests and calculated by the relationships established by the Brazilian Standard ABNT NBR 7190:1997. By the results of the hypothesis tests, it was possible to conclude that the estimate of the embedment strength parallel to the grain proposed by the Brazilian standard ABNT NBR 7190:1997, establishing equivalence with the strength compression results in the same direction, must be effective to the wood species Pinus taeda L., however, the same was not found in the perpendicular direction with respect to the grain, possibly explained by the alpha(e) values in the equation to calculed fe(90)

Estudo e aplicação da técnica de vibroacustografia em ensaios não destrutivos

A presença de falhas, trincas, furos e fadigas causam perturbações nos modos vibracionais (normais) de uma estrutura, por exemplo, tubos, gasodutos e peças metálicas. Uma vez conhecido o espectro de freqüência de uma estrutura instalada em condições normais (sem falhas), é possível acompanhar através, de ensaios não destrutivos uma alteração no espectro de freqüência que pode estar associado a alguma falha mecânica na estrutura.O presente trabalho busca encontrar um padrão nos sinais de resposta dos materiais analisados pela técnica de Vibroacustografia, antes e depois das deformidades causadas. Tentando viabilizar a técnica para a utilização em Ensaios Não Destrutivos (END). E futuramente, para as amostras biológicas, espera-se estender os conhecimentos obtidos dos ensaios anteriores para detecção e prevenção de possíveis fraturas do tecido ósseo

Análise de características físicas de agregados de resíduos de construção e demolição, para fins de pavimentação

This work presents the results obtained in analyzes of aggregates from construction and demolition waste produced by the plant of the City of Guaratinguetá. Using this data and comparing with the specifications of NBR 15115, it was found that the materials do not possess the requisite minimum characteristics to be utilized as a basis for low-pavement traffic. In order to identify the main reasons of the material does not fit in the standard, we used the data obtained in a study conducted by Professor. Dr. Luiz Eduardo de Oliveira at the plant of the company AB Environmental Solutions Ltd., located in Pindamonhangaba. With different characteristics, the aggregates from construction and demolition waste produced by this plant showed the possibility of using pavements. The use of these residues in paving reduces the impact on the environment caused by construction.

Proposta de conector para ensaios de ligações CDE submetidas à tração perpendicular as fibras em madeira de pinus

The growth of urban population associated with the shortage of supply of public infrastructure such as hospitals, kindergartens, schools, among others, has reinforced the need to develop alternative methods that simplify the construction processes and allows for a reduction in these costs works. The conventional processes have increasingly been shown ineffective to solve the problem of demand for different types of urban and rural buildings. Given this fact, industrial construction processes can gain space and have proven to be highly interesting to solve the above problems, in particular, considering the cost-effective and time. Therefore, this study aimed to determine the influence of moisture on the strength of metal plate connections connectors (printed plate with teeth). For the sizing of the links between structural lumber using metal connectors with teeth prints; controlled process variables (drying of the wood and the different moisture contents), and finally found results and compare them with different literatures order to obtain a qualitative efficiency of the process. Some specimens had very low expectations, can be explained by the presence of bone marrow, and pre-existing cracks. Thus, the results were discarded for further analysis and more accurate results

Desenvolvimento e caracterização de sistemas líquido-cristalinos para aplicação tópica de metotrexato: estudo da bioadesão e ensaios biológicos in vitro

A psoríase é uma doença inflamatória relativamente comum da pele e das articulações, podendo se tornar crônica. Nos últimos anos, a expansão do arsenal terapêutico para o paciente com psoríase tem permitido aos médicos combaterem, de forma mais agressiva, a patogênese da doença. Um fármaco utilizado para o tratamento é o metotrexato, que, apesar de ser bastante eficaz, possui potencial para a toxicidade sistêmica, como toxicidade hematológica, hepática e pulmonar. Sendo assim, muita atenção tem sido dada ao desenvolvimento de novos veículos com o objetivo não só de aumentar a eficácia terapêutica de substâncias ativas, como também de permitir a redução da sua dose total necessária, minimizando os efeitos colaterais tóxicos. Os cristais-líquidos são sistemas promissores para aplicação tópica, pois promovem liberação controlada de fármacos, contribuindo para amenizar efeitos adversos, por exemplo, do metotrexato. Uma vez que há possibilidade de as substâncias incorporadas em formulações tópicas serem absorvidas pela pele e mucosas, existe a necessidade de garantir que as formulações sejam seguras. Este trabalho teve o objetivo de avaliar a bioadesão e a citotoxicidade in vitro de três sistemas líquido-cristalinos contendo metotrexato para o tratamento da psoríase. Resultados de bioadesão revelaram que as três formulações analisadas apresentaram forças bioadesivas próximas, sendo o sistema A mais bioadesivo. Com relação a estudos de reologia, houve comportamento de fluido não-newtoniano, pseudoplástico e tixotrópico. Além disso, a adição de metotrexato à formulação A, aumentou a viscosidade do sistema. Ensaios de citotoxicidade sugerem a possibilidade de liberação prolongada de metotrexato, contribuindo para o aumento da viabilidade celular
