Correlação entre gestão da tecnologia e gestão ambiental nas empresas

Este trabalho analisa a correlação entre a gestão da tecnologia de produtos e processos e a gestão ambiental em empresas de manufatura. Partindo de um modelo conceitual simplificado e desdobramentos das dimensões gestão da tecnologia e gestão ambiental, foi possível analisar em pesquisa de campo vários conceitos disponíveis na literatura para esses dois campos, envolvendo 78 empresas do setor de manufaturados, através de projeto de pesquisa survey e projeto de pesquisa qualitativa. Visando avaliar a capabilidade tecnológica das organizações, foram usados os conceitos de microtecnologia e macrotecnologia relatados em Silva (2003). Concluiu-se que, dentro do campo pesquisado de empresas, existe correlação positiva entre os níveis de capabilidade tecnológica e os níveis de capabilidade ambiental.

Adequação do teste de condutividade elétrica para sementes de Pisum sativum subsp. Arvense

A qualidade da semente na produção agrícola é um dos principais fatores a ser considerado na implantação da cultura, de forma que se torna importante a obtenção de informações sobre a germinação e o vigor das sementes, além da necessidade de avaliá-los. Dentro desse contexto, este trabalho teve como objetivo adequar a metodologia do teste de condutividade elétrica para a avaliação da qualidade fisiológica de sementes de Pisum sativum subsp. arvense. Para tanto, foram utilizados dez lotes de sementes da cultivar IAPAR 83, empregando-se períodos de condicionamento de 8, 16, 20, 24 e 28 horas, combinados às temperaturas de 20 e 25°C e volumes de 75 e 250mL de água. Além destes, foram conduzidos os testes de germinação, primeira contagem de germinação e emergência de plântulas. Para ambas as avaliações, foram utilizadas quatro repetições de 50 sementes. Os testes de vigor, assim como o teste de germinação foram sensíveis para avaliar a qualidade das sementes dos diferentes lotes estudados, porém houve variações na ordenação deles quanto ao vigor. O volume de água, o tempo e a temperatura de embebição influenciaram os valores de condutividade elétrica. Concluiu-se que o teste de condutividade elétrica utilizando 250mL de água, na temperatura de 25°C por 24 horas é promissor para a diferenciação de lotes de sementes de P. sativum subsp. arvense.

Áreas ecologicamente estáveis como instrumento de planejamento ambiental

The population growth phenomenon, coupled with recent urbanization, is seen in all continents and generates huge pressures on the physical and biotic environment, resulting in floods in several areas, desertification in others, and also various forms of pollution that cause serious problems to human health. It is appropriate to ask, what actions can be implemented in consolidated urban areas to improve the quality of life in this environment? What growth alternatives present themselves to today's society in order to keep an acceptable level of environmental quality in urban centers? A possibility is presented herein, stemming from the application of the Biotope Area Factor (BAF; www.stadtentwicklung.berlin.de) to an area of a Brazilian municipality. Current growing waterproofing requirements fur lots of the area were assesed, comparing them with those that would be desirable by the implementation of the BAF. The associated costs of this deployment are also discussed.

Nova proposta de critério de retenção para dimensionamento de filtros têxteis

The designs of filters made by granular material or textile are mainly based on empirical or semi empirical retention criteria according to Terzaghi proposal, which compares particle diameter of the soil base with the filter porous spaces. Silveira in 1965, proposed one rational design retention criteria based on the probability of a particle from the soil base, carried by one dimensional flow, be restrained by the porous of the filter while trying to pass through its thickness. This new innovating theory, besides of being very simple, it is not frequently used for granular filters since the necessary parameters for the design has to be determine for each natural material. However, for textile this problem no longer exists because it has quality control during manufacturing and the necessary characteristics properties of the product are specify in the product catalog. This work presents one adaptation of the Silveira theory for textile filters and the step-by-step procedure for the determination of the characteristics properties of the textile products necessary for the design. This new procedure permits the determination of the confiability level of retention that one specific particle diameter form the soil base has for one specified textile. One complete example is presented to demonstrate the simplicity of the method proposed and how the textile characteristics are obtained.

The temporal resolution of epibiont assemblages: Are they ecological snapshots or overexposures?

The effects of time averaging on the fossil record of soft-substrate marine faunas have been investigated in great detail, but the temporal resolution of epibiont assemblages has been inferred only from limited-duration deployment experiments. Individually dated shells provide insight into the temporal resolution of epibiont assemblages and the taphonomic history of their hosts over decades to centuries. Epibiont abundance and richness were evaluated for 86 dated valves of the rhynchonelliform brachiopod Bouchardia rosea collected from the inner shelf. Maximum abundance occurred on shells less than 400 yr old, and maximum diversity was attained within a century. Taphonomic evidence does not support models of live-host colonization, net accumulation, or erasure of epibionts over time. Encrustation appears to have occurred during a brief interval between host death and burial, with no evidence of significant recolonization of exhumed shells. Epibiont assemblages of individually dated shells preserve ecological snapshots, despite host-shell time averaging, and may record long-term ecological changes or anthropogenic environmental changes. Unless the ages of individual shells are directly estimated, however, pooling shells of different ages artificially reduces the temporal resolution of their encrusting assemblages to that of their hosts, an artifact of analytical time averaging. © 2006 by The University of Chicago.

Sistemas biodegradáveis contendo acetato de prednisolona para administração orbitária

Purpose: The present study aimed to evaluate an injectable extended-release formulation of prednisolone acetate (PA) for orbital administration. Methods: Microspheres (MEs) of poly-ε-caprolactone (PCL) containing PA were developed by the method of solvent evaporation. The MEs obtained were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), encapsulation efficiency and in vitro release profile. The in vivo release profile was evaluated in rabbits after periocular injection of an aqueous suspension of MEs. The local biocompatibility of the system was verified by histopathologic analysis of the deployment region. Results: After MEs preparation, morphological analysis by SEM showed the feasibility of the employed method. The content of PA encapsulated was 43 ± 7% and can be considered as satisfactory. The system characterization by DSC technique, in addition to confirm the system stability, did not indicate the existence of interaction between the drug and the polymer. The in vitro release study showed the prolonged-release features of the developed system. Preliminary in vivo study showed the absence of local toxicity and confirmed the prolonged release profile of PA from MEs, suggesting the viability of the developed system for the treatment of orbital inflammatory diseases. Conclusion: The results obtained in this work are relevant and accredit the system developed as a possible alternative to the treatment of inflammatory orbitopathy.

Estatística de levantamentos epidemiológicos sobre cárie dentária, publicados no brasil e no exterior, de 1960 a 2001

The epidemiological surveys are important to the deployment, implementation and evaluation of projects and health actions in a community. The planning, goals, samples, team training/calibration, carrying out and publication of results are extremely important in the epidemiological surveys. Thus, the care with the sample and statistical analysis is fundamental for the results to be consistent and trustworthy in order to be able to be inferred for all the population. The aims of this study is to investigate the statistical methodology used in papers on dental caries epidemiological surveys published from 1960 to 2001. A bibliographical survey was carried out in BBO, MEDLINE and SCIELO databases. The papers found were analyzed with regards to the statistical methodology applied in the whole study, from the sampling to the tabling of data. Most studies (72.6%) only presented the number of elements that composed the sample, without explaining the planning involved in obtaining it.

Dinâmica regional e política urbana: Uma análise das cidades de porte médio da região administrativa de Campinas/SP

The process of internalization of development occurred in the state of Sao Paulo resulted in accelerated growth of intermediate cities leading to a pattern of development with sprawl, segregation and suburbanization. In this process stands the Administrative Region of Campinas, the hinterland region of higher growth and accumulating a larger number of medium-sized cities. Such questions imply the need for appropriate urban policies to confront these challenges, under risk to jeopardize the quality of life and environment of these cities. The implementation of the Estatuto da Cidade brings new perspectives for urban management in medium-sized cities. This study aims to evaluate the deployment of instruments of urban management in medium-sized cities in São Paulo, with emphasis on Administrative Region of Campinas, based on the Profile of Brazilian Municipalities 2008 conducted by IBGE. The results point to a worrying situation, as it did not see a correlation between the deployment of these instruments and the size, growth and income in the mid-sized cities.
