Validação das unidades arbitrárias do teor de clorofilas obtido em folhas intactas de seringueira

The determination of foliar chlorophyll content is a characteristic that interests ecophysiologists and rural producers. With consideration for practical uses as well as scientific publications, our present work aims to establish equations, for rubber tree leaves, that can convert arbitrary units of expressing chlorophyll content to the international system. Chlorophyll a (Chla), chlorophyll b (Chlb), and total chlorophyll (Chltot) were obtained from intact leaves using a portable chlorophyll detecting instrument. Leaves from different positions on the plant, at various stages of maturity, and representing a large spectrum of pigment concentrations, were collected and analyzed in the field using the Clorofil OG Falkner ® instrument, through four evaluations in forty-five medium leaflets. At the laboratory, leaflets underwent a process of pigment extraction. They were incubated in a water-bath with dimethylsulfoxide (DMSO), dosed in molecular absorption spectrophotometer, and converted into pigment content per unit of fresh weight using conventional equations. The data were evaluated according to the Pearson correlation coefficient and tested with different regression models. For all variables, the linear fit is the most adequate, with correlation coefficients (r) 0.74 for Chlb and 0.88 for Chla and Chltott .

Toxic heritage: maternal transfer of pyrethroid insecticides and sunscreen agents in dolphins from Brazil

Pyrethroids (PYR) and UV filters (UVF) were investigated in tissues of paired mother-fetus dolphins from Brazilian coast in order to investigate the possibility of maternal transfer of these emerging contaminants. Comparison of PYR and UVF concentrations in maternal and fetal blubber revealed Franciscana transferred efficiently both contaminants to fetuses (F/M > 1) and Guiana dolphin transferred efficiently PYR to fetuses (F/M > 1) different than UVF (F/M < 1). PYR and UVF concentrations in fetuses were the highest-ever reported in biota (up to 6640 and 11,530 ng/g lw, respectively). Muscle was the organ with the highest PYR and UVF concentrations (p < 0.001), suggesting that these two classes of emerging contaminants may have more affinity for proteins than for lipids. The high PYR and UVF concentrations found in fetuses demonstrate these compounds are efficiently transferred through placenta. This study is the first to report maternal transfer of pyrethroids and UV filters in marine mammals.

Criação de contexto favorável ao compartilhamento do conhecimento operário: pesquisa no ambiente vidreiro

In search for better competitiveness, the automotive industry has discussed and applied several concepts related to people and processes. However, in many organizations, the adopted concepts are implemented and kept unarticulated. In this context, authors recognize the role of the knowledge as competitive advantage, but it is still dealt in an implicit way with the traditional models of Production Management. Exploring opportunities in this scenario, this Thesis aims to analyse worker knowledge sharing using factors of Knowledge Management, Work Organization and Production Organization. For the realization of the present Thesis, the scope of the research was restricted to be the labour environment of the glass plants shop floor. The choice of the glass sector is justified due to high dependency on the tacit knowledge of blue-collars. The research uses a qualitative-quantitative approach and employs interviews with workers and managers to identify factors. To assess the importance of these factors in the management judgments, is employed the technique Incomplete Pairwise Comparisons based on Analytic Hierarchy Process Saaty (2001). The result indicates integration among factors and highlights the importance of systematic and technical conversation among operators to share better your knowledge. Also, worker knowledge sharing is improved using communication, training and work instruction. This research extends the conceptual frameworks encountered in literature from the factors integration of Knowledge Management with the Organization of Work and the Production and makes explicit use of the theme of knowledge. This contributes to promote of a favourable context for the creation and sharing of knowledge, among the people in the labour environment, and to support incremental innovation

Mapeamento do conhecimento no processode atribuição de aulas em Escolas Técnicas

This article has the objective to describe the importance of management knowledge. And, for that, we have done a study upon a case, based on the mapping of the process of classes distribution in the Escolas Técnicas do Centro Paula Souza. The management of knowledge is a way to provide it to the people, considering that knowledge becomes a fundamental and necessary resource to the development of the privante or public organizations. The use of knowledge maps becomes a crucial factor in this process of transformation of tacit knowledge into explicit, because having a high knowledge level, and socialize it, is as essential and important as all the other resources that exist within the institutions.

Effect of infill panels on the seismic response of a typical R.C. frame

Three structural typologies has been evaluated based on the nonlinear dynamic analysis (i.e. Newmark's methods for MDFs: average acceleration method with Modified Newton-Raphson iteration). Those structural typologies differ each other only for the infills presence and placement. In particular, with the term BARE FRAME: the model of the structure has two identical frames, arranged in parallel. This model constitutes the base for the generation of the other two typologies, through the addition of non-bearing walls. Whereas with the term INFILLED FRAME: the model is achieved by adding twelve infill panels, all placed in the same frame. Finally with the term PILOTIS: the model has been generated to represent structures where the first floor has no walls. Therefore the infills are positioned in only one frame in its three upper floors. All three models have been subjected to ten accelerograms using the software DRAIN 2000.
