Conversion between basic density and apparent density at any moisture content in Eucalyptus grandis

Wood basic density (BD) is related to other wood characteristics and its determination is important in forest inventory, though BD must be differentiated from the apparent density (AD), which relates to the moisture content (MC) of wood. The aim of this study is to demonstrate a reliable conversion from BD to AD for any MC of Eucalyptus grandis wood based on two exponential and linear models that relate volumetric shrinkage to MC. To this end, wood specimens were submitted to drying and the volumetric shrinkage was determined as a function of MC. The two models proved to be efficient in the conversion of BD to AD and vice versa.

Comparison of polymers and ceramics in new and discarded electrical insulators: reuse and recycling possibilities

The expansion and maintenance of electricity distribution networks generates large amounts of waste, much of it in the form of discarded insulators that are not reused or recycled. This paper describes the results of tests on used and new ceramic and polymeric insulators to verify if their exposure to weathering justifies their replacement. In new and used ceramic insulators, properties such as contact angle, relative density, porosimetry, dilatometry and X-ray diffraction patterns showed no differences or the differences that were found could not be related to their use. The discarded ceramic material showed high thermal stability, an interesting characteristic for application as chamotte. It can also be reused to replace gravel used in substations. In polymeric insulators, thermogravimetry, differential scanning calorimetry and relative density test results suggest degradation of used material compared to new. This would justify their replacement and discard as waste, but they show little recycling potential.

Análise comparativa de duas versões do conto de Cinderela: a de Charles Perrault e a dos Irmãos Grimm

A importância que é atribuída ao ato da leitura serviu como princípio para nortear este estudo, que se utiliza do conto da Cinderela para aprofundar a reflexão a respeito da relação entre o tipo de leitores que estamos formando e aquele que desejamos formar. Sistematizando, por meio da teoria de Vladimir Propp, nossa análise das versões de Charles Perrault e dos Irmãos Grimm do conto de Cinderela, obtemos importantes conclusões a respeito de como o conto se contextualiza de acordo com as sociedades vigentes. Desse modo, este estudo permitiu o aprofundamento necessário para que nós, como profissionais responsáveis pela formação do sujeito e do leitor, nos atentemos a aspectos e valores contidos em cada versão do conto e que nos esforcemos em trabalhá-los junto aos nossos educandos. Retomamos ainda algumas produções contemporâneas a respeito do enredo da Gata Borralheira, para situar a concepção que fazemos deste conto e desta personagem ainda hoje. As reflexões finais ficaram responsáveis por apresentar algumas possibilidades de trabalho que o educador pode pensar para levar para a sala de aula

Conto de fadas: Pele de asno de Charels Perrault, e sua retomada na modernidade por Marina Colasanti

Como base de estudo para esta pesquisa, buscaremos a comparação dos contos de fadas Pele de Asno de Charles Perrault, e sua retomada na modernidade em Entre a Espada e a Rosa por Marina Colasanti. O qual proveniente da cultura oral vem a encantar crianças e adultos por toda as gerações. Esses tão conhecidos contos sempre tiveram, como objetivo, desde seu nascimento, no século XVII, a perpetuação de valores e condutas a serem seguidas. E que hoje vem sendo utilizada como um instrumento superficial e didático, reduzindo as grandes obras clássicas em meras historinhas para passar o tempo. Recebendo ainda a critica direta que tal gênero vem determinar valores nas crianças, trataremos de analisar esses contos através das considerações apontadas por Propp em seus estudos. Assim tem-se como objetivos norteadores desta pesquisa, a comparação entre as características dessas narrativas, mantendo seus contextos histórico; as funções atribuídas pelo estruturalista russo em ambas as narrativas e suas representações na vida, contrapondo as criticas apontadas a cerca desse gênero literário

Processo de medição de desempenho em micro e pequenas empresas de um arranjo produtivo local

The local productive arrangements (LPA) are organizational mechanisms that enable the continuous performance of small businesses in production processes and business management models. To promote continuous improvement is essential that companies make decisions based on data that reflects business’ performance (performance measurement) and promote the cluster performance. This way, the aim of this article is to describe the performance measurement process that will support the corporate management of Micro and Small enterprises (SME) of a Local Productive Arrangement in Maringá, State of Paraná, Brazil. To develop this paper, the bibliographic search and action research methods were used. The field research was developed from the cooperation project (PROJVEST) conducted at the LPA, which goal is to deploy improvement actions in project’s participating companies. Metrics and performance indicators constructed from the diagnosis in the areas of Production, Quality and Ergonomics in companies will be presented. Among the main results, can be pointed out that the performance management of LPA is promoting the introduction of corporate management practices in SMEs, stimulating business cooperation, the continuous innovation in manufacturing processes and product quality and business processes.

Oportunidades de melhoria na gestão de resíduos em empresas distribuidoras de eletricidade: o caso da AES Eletropaulo

A gestão de resíduos em distribuidoras de eletricidade é bastante complexa, pois enquadram-se em vários tipos (valorizados ou não) e gerados em grande quantidade. Em 2009, a AES Eletropaulo gerou quase quatro mil toneladas de resíduos não perigosos, subdivididos em 30 tipos. Uma divisão por materiais, após desmontagem e separação dos diferentes materiais contidos nos fios, cabos, chaves, isoladores com ferragem e para-raios, subiria o valor da venda em R$ 600 mil. Isso geraria cerca de 214 toneladas de porcelana que, moídas, poderiam substituir as 210 toneladas de brita compradas anualmente pela concessionária para uso em subestações. Cerca de 160 toneladas de porcelanas intactas poderiam ser utilizadas na confecção de gabiões para contenção de encostas. Além disso, peças de ferro galvanizado poderiam ser decapadas e novamente galvanizadas para reaproveitamento.

Variation of soil and water volumes in riparian jungle soils of Brazil

The objective of this work is to study the relation between humidity, density, porosity and shrinkage of the floodplain soil and riparian vegetation and their ability to store water. For this purpose, two locations for every type of soils were evaluated. Both were placed at the Agronomy University (Faculdade de Ciências Agronômicas) in São Manuel, State of São Paulo, Brazil. The floodplain soil was vegetated with Southern Cattail (Typha domingensis). In both places, soil samples were collected from several depths: 0, 30, 60 and 100 cm. Results show that lower soil density values (0.15 g/cm3) with organic texture and high porosities values (up to 86.2%) were found in samples with the highest organic material content in the floodplain soil. For this field experiment, flood plains soils (characterised as basin gley soils) presented high volumetric instability with a retratibility of 67.49% and higher water storage capacities compared to riparian stands soils (characterised as fluvic neosoils).

Ynari, a menina das cinco tranças: uma análise proppiana

This work consists, mainly, in the analysis of an Angolan children contemporary work of literature trough a traditional methodology for the study of fairy tales, in other words, Vladimir Propp's. His goal is to prove this methodology, besides having been specifically developed to analyze European folktales, has an application of big range, including contemporary work and of non-european origin. He demonstrates which were the results and difficulties of such applicability. Besides, it was also found relevant affirmations about the history of Angola and about the biography of the author of the studied biography, Ondjaki

Killer Whales and Marine Mammal Trends in The North Pacific—A Re-Examination of Evidence for Sequential Megafauna Collapse and the Prey-Switching Hypothesis

Springer et al. (2003) contend that sequential declines occurred in North Pacific populations of harbor and fur seals, Steller sea lions, and sea otters. They hypothesize that these were due to increased predation by killer whales, when industrial whaling’s removal of large whales as a supposed primary food source precipitated a prey switch. Using a regional approach, we reexamined whale catch data, killer whale predation observations, and the current biomass and trends of potential prey, and found little support for the prey-switching hypothesis. Large whale biomass in the Bering Sea did not decline as much as suggested by Springer et al., and much of the reduction occurred 50–100 yr ago, well before the declines of pinnipeds and sea otters began; thus, the need to switch prey starting in the 1970s is doubtful. With the sole exception that the sea otter decline followed the decline of pinnipeds, the reported declines were not in fact sequential. Given this, it is unlikely that a sequential megafaunal collapse from whales to sea otters occurred. The spatial and temporal patterns of pinniped and sea otter population trends are more complex than Springer et al. suggest, and are often inconsistent with their hypothesis. Populations remained stable or increased in many areas, despite extensive historical whaling and high killer whale abundance. Furthermore, observed killer whale predation has largely involved pinnipeds and small cetaceans; there is little evidence that large whales were ever a major prey item in high latitudes. Small cetaceans (ignored by Springer et al.) were likely abundant throughout the period. Overall, we suggest that the Springer et al. hypothesis represents a misleading and simplistic view of events and trophic relationships within this complex marine ecosystem.
