Curial exegese do art. 14, caput, da lei 9.307/96: hermenêutica lege ferenda ou real vontade do legislador?

Considerando toda a evolução da ciência processual, não há mais qualquer dúvida acerca da importância de se garantir juízes imparciais para o exercício da atividade jurisdicional. Em sede de arbitragem, a preocupação não poderia ser diferente. Dado que o árbitro exerce igualmente as prerrogativas concedidas pela jurisdição, sendo árbitro de fato e de direito, a necessidade de que sejam pessoas munidas de inquestionável imparcialidade e independência em relação às partes é ainda maior, dado que a confiança é o principal requisito para a função de tal munus. Desta forma, o trabalho pretende compreender se pode o princípio da autonomia da vontade das partes relativizar a proibição estabelecida em lei, que impede a atuação de árbitros quando incidentes nas hipóteses de impedimento e suspeição.

Synthetic and natural polycations for gene therapy: State of the art and new perspectives

Currently, the major drawback of gene therapy is the gene transfection rate. The two main types of vectors that. are used in gene therapy are based on viral or non-viral gene delivery systems. There are several non-viral systems that can be used to transfer foreign genetic material into the human body. In order to do so, the DNA to be transferred must escape the processes that affect the disposition of macromolecules. These processes include the interaction with blood components, vascular endothelial cells and uptake by the reticuloendothelial system. Furthermore, the degradation of therapeutic DNA by serum nucleases is also a potential obstacle for functional delivery to the target cell. Cationic polymers have a great potential for DNA complexation and may be useful as non-viral vectors for gene therapy applications. The objective of this review was to address the state of the art in gene therapy using synthetic and natural polycations and the latest strategies to improve the efficiency of gene transfer into the cell.

Clinical evaluation of multisurface ART restorations

O objetivo deste estudo foi avaliar o comportamento de dois cimentos de ionômero de vidro: um de alta viscosidade (Ketac Molar - ESPE) e um modificado por resina (Fuji VIII – GC) em restaurações envolvendo duas ou mais superfícies dentárias, confeccionadas pela técnica do Tratamento Restaurador Atraumático. Sessenta restaurações (30 com cada material) foram inseridas em estudantes (9-16 anos) por dois operadores. Após 6 meses, dois examinadores independentes avaliaram as restaurações de acordo com os critérios utilizados em trabalhos prévios semelhantes. Os dados foram analisados pelos testes de McNemar e Fischer. A porcentagem de sucesso do tratamento foi de 98,3%. Uma restauração (Ketac Molar) foi substituída por outro material e classificada como falha. As porcentagens de sucesso das restaurações foram de 100% e 96,6% para o Fuji VIII e Ketac Molar, respectivamente. Não houve diferença estatisticamente significante no sucesso das restaurações entre o baseline e 6 meses (p>0,05). Da mesma forma, não houve diferença estatística entre os materiais, tipos de cavidade ou entre operadores.(p>0,05). A técnica ART foi altamente apropriada e efetiva em restaurações envolvendo duas ou mais superfícies, após 6 meses. Os resultados mostraram um comportamento promissor com ambos os materiais.

Rock Art at the Pleistocene/Holocene Boundary in Eastern South America

Background: Most investigations regarding the First Americans have primarily focused on four themes: when the New World was settled by humans; where they came from; how many migrations or colonization pulses from elsewhere were involved in the process; and what kinds of subsistence patterns and material culture they developed during the first millennia of colonization. Little is known, however, about the symbolic world of the first humans who settled the New World, because artistic manifestations either as rock-art, ornaments, and portable art objects dated to the Pleistocene/Holocene transition are exceedingly rare in the Americas. Methodology/Principal Findings: Here we report a pecked anthropomorphic figure engraved in the bedrock of Lapa do Santo, an archaeological site located in Central Brazil. The horizontal projection of the radiocarbon ages obtained at the north profile suggests a minimum age of 9,370640 BP, (cal BP 10,700 to 10,500) for the petroglyph that is further supported by optically stimulated luminescence (OSL) dates from sediment in the same stratigraphic unit, located between two ages from 11.7 +/- 0.8 ka BP to 9.9 +/- 0.7 ka BP. Conclusions: These data allow us to suggest that the anthropomorphic figure is the oldest reliably dated figurative petroglyph ever found in the New World, indicating that cultural variability during the Pleistocene/Holocene boundary in South America was not restricted to stone tools and subsistence, but also encompassed the symbolic dimension.

An Integrated Transmission-Media Noise Calibration Software For Deep-Space Radio Science Experiments

The thesis describes the implementation of a calibration, format-translation and data conditioning software for radiometric tracking data of deep-space spacecraft. All of the available propagation-media noise rejection techniques available as features in the code are covered in their mathematical formulations, performance and software implementations. Some techniques are retrieved from literature and current state of the art, while other algorithms have been conceived ex novo. All of the three typical deep-space refractive environments (solar plasma, ionosphere, troposphere) are dealt with by employing specific subroutines. Specific attention has been reserved to the GNSS-based tropospheric path delay calibration subroutine, since it is the most bulky module of the software suite, in terms of both the sheer number of lines of code, and development time. The software is currently in its final stage of development and once completed will serve as a pre-processing stage for orbit determination codes. Calibration of transmission-media noise sources in radiometric observables proved to be an essential operation to be performed of radiometric data in order to meet the more and more demanding error budget requirements of modern deep-space missions. A completely autonomous and all-around propagation-media calibration software is a novelty in orbit determination, although standalone codes are currently employed by ESA and NASA. The described S/W is planned to be compatible with the current standards for tropospheric noise calibration used by both these agencies like the AMC, TSAC and ESA IFMS weather data, and it natively works with the Tracking Data Message file format (TDM) adopted by CCSDS as standard aimed to promote and simplify inter-agency collaboration.

Adjusting mortality for loss to follow-up: analysis of five ART programmes in sub-Saharan Africa

Evaluation of antiretroviral treatment (ART) programmes in sub-Saharan Africa is difficult because many patients are lost to follow-up. Outcomes in these patients are generally unknown but studies tracing patients have shown mortality to be high. We adjusted programme-level mortality in the first year of antiretroviral treatment (ART) for excess mortality in patients lost to follow-up.

Can Developing Women Create Primitive Art? and Other Questions of Value, Meaning and Identity in the Circulation of Janakpur Art

In this article, I examine the values and meanings that adhere to objects made by Maithil women at a development project in Janakpur, Nepal – objects collectors have called ‘Janakpur Art’. I seek to explain how and why changes in pictorial content in Janakpur Art – shifts that took place over a period of five or six years in the 1990s – occurred, and what such a change might indicate about the link between Maithil women’s lives, development, and tourism. As I will demonstrate, part of the appeal for consumers of Janakpur Art has been that it is produced at a ‘women’s development project’ seeking to empower its participants. And yet, the project’s very successes threaten to displace the producers (and what they produce) from their perceived qualities/identities as ‘traditional’ and ‘primitive,’ thereby bringing into question the authenticity of the ‘art’ they produce. The conundrum begs this question: can developing women produce primitive art?
