H.L.A. Hart: a hermenêutica como via de acesso para uma significação interdisciplinar do direito
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina. Centro de Ciencias JuridicasO presente trabalho tem por objetivo analisar a teoria jurídica de Herbert Lionel Adolphus Hart, a partir de uma (re)leitura da Filosofia da Linguagem Ordinária (especialmente através de Ludwig Wittgenstein e John Lagshaw Austin) e da semiologia (através das categorias de Ferdinand de Saussure). Tal método deriva do fato de Hart realizar uma abordagem do direito a partir de uma perspectiva hermenêutica, privilegiando a função do intérprete (participante) do sistema e destacando o papel exercido pela linguagem na formação dos enunciados jurídicos. Ao mesmo tempo, ao reconhecer uma textura aberta do direito, este autor abre a ciência jurídica à possibilidade de uma abordagem interdisciplinar. Inicialmente realizamos uma leitura da obra de WITT-GENSTEIN, com especial atenção à segunda fase de sua obra, marcada pela publicação do livro Investigações Filosóficas, procurando uma compreensão da linguagem enquanto instrumento de intermediação na relação sujeito-sujeito. Em seguida apresentamos a "teoria dos atos de fala" de J.L. AUSTIN, a qual nos possibilitará responder a questão de como as palavras podem produzir efeitos jurídicos. O capítulo I contém ainda a exposição das principais categorias de SAUSSURE, objetivando explicitar a sua concepção dos signos lingüísticos e do processo de significação. Em seguida, no capítulo II, procuramos explicitar a concepção de Hart acerca do fenômeno da obrigação jurídica, enfocando o caráter hermenêutico da sua teoria jurídica e demonstrando a importância daquilo que este autor denomina o "ponto de vista interno" sobre as normas. O capítulo III destina-se a fornecer uma compreensão da estrutura global do sistema jurídico de HART, entendido como a união de normas primárias e secundárias e destacando o seu funcionamento. Realizamos ainda uma abordagem da textura aberta do direito, procurando enfatizar o caráter incompleto dos enunciados jurídicos e de que forma o direito operacionaliza esta questão. Ao final do trabalho, apresentamos uma síntese crítica do pensamento de Hart, objetivando levantar as questões que permanecem na sua obra e algumas das críticas que lhe são feitas

Ultraviolet radiation suppresses obesity and symptoms of metabolic syndrome independently of vitamin d in mice fed a high-fat diet
No full textThe role of vitamin D in curtailing the development of obesity and comorbidities such as the metabolic syndrome (MetS) and type 2 diabetes has received much attention recently. However, clinical trials have failed to conclusively demonstrate the benefits of vitamin D supplementation. In most studies, serum 25-hydroxyvitamin D [25(OH)D] decreases with increasing BMI above normal weight. These low 25(OH)D levels may also be a proxy for reduced exposure to sunlight-derived ultraviolet radiation (UVR). Here we investigate whether UVR and/or vitamin D supplementation modifies the development of obesity and type 2 diabetes in a murine model of obesity. Long-term suberythemal and erythemal UVR significantly suppressed weight gain, glucose intolerance, insulin resistance, nonalcoholic fatty liver disease measures; and serum levels of fasting insulin, glucose, and cholesterol in C57BL/6 male mice fed a high-fat diet. However, many of the benefits of UVR were not reproduced by vitamin D supplementation. In further mechanistic studies, skin induction of the UVR-induced mediator nitric oxide (NO) reproduced many of the effects of UVR. These studies suggest that UVR (sunlight exposure) may be an effective means of suppressing the development of obesity and MetS, through mechanisms that are independent of vitamin D but dependent on other UVR-induced mediators such as NO.</p
The effect of blade aerodynamic modelling on the prediction of the blade airloads and the acoustic signature of the HART II rotor
No full textAs a rotorcraft descends or manoeuvres, the interactions which occur between the rotor blades and vortical structures within the rotor wake produce highly impulsive loads on the blades and with these a highly intrusive external noise. Brown's Vorticity Transport Model has been used to investigate the influence of the fidelity of the local blade aerodynamic model on the quality of the prediction of the high-frequency airloads associated with blade-vortex interactions and thus on the accuracy with which the acoustic signature of the aircraft can be predicted. The Vorticity Transport Model can resolve very accurately the structure of the wake, and allows significant flexibility in the way that the blade loading can be represented. The predictions of two models for the local blade aerodynamics are compared for all three of the HART II flight cases. The first model is a simple lifting-line model and the second is a somewhat more sophisticated lifting-chord model based on unsteady thin aerofoil theory. A marked improvement in accuracy of the predicted high-frequency airloads and acoustic signature of the HART II rotor is obtained when the lifting-chord model for the blade aerodynamics is used instead of the lifting-line type approach. Errors in the amplitude and phase of the loading peaks are reduced and the quality of the prediction is affected to a lesser extent by the computational resolution of the wake. Predictions of the acoustic signature of the rotor are similarly affected, with the lifting-chord model at the highest resolution producing the best representation of the distribution of sound pressure on the ground plane below the rotor
Predicting the wake structure of the HART II rotor using the vorticity transport model
No full textBrown’s Vorticity Transport Model has been used to predict the wake structure and resultant
blade loading of the rotor that was studied during the HART II experimental programme.
The descending flight condition of the experiment yields significant high-frequency content to
the blade loading due to the presence of blade-vortex interactions. PIV images of the wake
structure were compared against numerical predictions of the detailed geometry of the rotor
wake using three different computational resolutions of the flow. This was done to investigate
the origin of inaccuracies exposed in an earlier study of the system in capturing the effects of
blade vortex interactions on the loading on the rotor. The predicted positions of the vortex
cores agree with measured data to within a fraction of the blade chord, and the strength of the
vortices is preserved to well downstream of the rotor, essentially independently of the resolution
of the calculation. Nevertheless the amplitude of the loading impulses induced on the blade by
vortex interaction are strongly influenced by the resolution of the calculation through the effect
of cell density on the minimum vortex core size that can be supported. It would appear thus
that the inaccuracies in predicting the high-frequency loading on the rotor are not due to any
inherent deficiency in the representation of the wake, although viscous effects may need to be
considered in future in order to decouple the vortex core size from the cell size, but rather due
to the inherent deficiencies of the lifting line approach used to model the blade aerodynamics
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
O(d+1, d+1) enhanced double field theory
No full text© 2017, The Author(s). Double field theory yields a formulation of the low-energy effective action of bosonic string theory and half-maximal supergravities that is covariant under the T-duality group O(d, d) emerging on a torus T d . Upon reduction to three spacetime dimensions and dualisation of vector fields into scalars, the symmetry group is enhanced to O(d+1, d+1). We construct an enhanced double field theory with internal coordinates in the adjoint representation of O(d + 1, d + 1). Its section constraints admit two inequivalent solutions, encoding in particular the embedding of D = 6 chiral and non-chiral theories, respectively. As an application we define consistent generalized Scherk-Schwarz reductions using a novel notion of generalized parallelization. This allows us to prove the consistency of the truncations of D = 6, N= (1 1) and D = 6, N= (2 0) supergravity on AdS 3 × S 3
