Evaluation of patients' discomfort regarding regional anesthesia: 8AP6‐7

Background and Goal of Study: Regional anesthesia may cause physical and psychological discomfort. 50% of patients scheduled for urologic procedures undergo regional anesthesia, and their comfort represents a concern to the anesthesiologist. This study aims to: 1. identify factors related to patients’ discomfort regarding regional anesthesia(position for anesthesia and surgery procedures, puncture site pain, room temperature, audio-visual perception, sensitive/motor blockade); 2. Evaluate patients’ satisfaction with anesthesia. Materials and Methods: Af ter approval from the Hospital Ethics Committee all patients over 18years old, scheduled for urologic surgery, understanding Portuguese and anesthetized with spinal anesthesia were included. Patients in day case surgery or with incomplete medical records were excluded. We performed a questionnaire(with closed ended questions) in the first 24 hours af ter surgery and consulted anesthesia records. We asked yes or no questions, used a 1-10 scale to evaluate pain and a 1-4 scale to evaluate satisfaction. Because there isn’t a valid questionnaire in the literature to evaluate what we aimed to, we created one based on multiple articles1,2. Results and Discussion: 50patients were included; mean age 65 years old (min.32, max.89); 78% males and 70% ASAII. 75%denied discomfort during positioning for back puncture and 58% referred cold during anesthesia or surgery. One person was uncomfortable in the surgical position and no one considered being awake uncomfortable; sensitive/motor blockade was uncomfortable for 22%. Spinal was more painful than the venous puncture for32%; for 50%venous puncture was more painful and for 18%pain was similar. Patients were satisfied or very satisfied with the anesthetic technique and would choose the same technique in the future in 98% of cases. Conclusion: Although this questionnaire is not validated, it allowed us to understand that cold during anesthesia/surgery is a problem for most patients but this is easily solved. It also showed us that most patients are not uncomfortable with positioning during procedures, being awake and not feeling the legs.Interestingly only about one third of the patients thought that the back puncture was more painful than the venous puncture. In general we consider spinal anesthesia a good choice for these patients and we are satisfied that patients don’t find it uncomfortable and are also satisfie

Non Abelian Sugawara Construction and the q-deformed N=2 Superconformal Algebra

The construction of a q-deformed N=2 superconformal algebra is proposed in terms of level 1 currents of ${\cal{U}}_{q} ({\widehat{su}}(2))$ quantum affine Lie algebra and a single real Fermi field. In particular, it suggests the expression for the q-deformed Energy-Momentum tensor in the Sugawara form. Its constituents generate two isomorphic quadratic algebraic structures. The generalization to ${\cal{U}}_{q} ({\widehat{su}}(N+1))$ is also proposed.Comment: AMSLATEX, 21page

Nontrivial temporal scaling in a Galilean stick-slip dynamics

We examine the stick-slip fluctuating response of a rough massive non-rotating cylinder moving on a rough inclined groove which is submitted to weak external perturbations and which is maintained well below the angle of repose. The experiments presented here, which are reminiscent of the Galileo's works with rolling objects on inclines, have brought in the last years important new insights into the friction between surfaces in relative motion and are of relevance for earthquakes, differing from classical block-spring models by the mechanism of energy input in the system. Robust nontrivial temporal scaling laws appearing in the dynamics of this system are reported, and it is shown that the time-support where dissipation occurs approaches a statistical fractal set with a fixed value of dimension. The distribution of periods of inactivity in the intermittent motion of the cylinder is also studied and found to be closely related to the lacunarity of a random version of the classic triadic Cantor set on the line.Comment: 7 pages including 6 figure

Estudo preliminar da compatibilidade da variedade Thompson Seedless sobre 10 porta-enxertos.

Tendo em vista a grande variação de comportamento da combinação copa x porta-enxerto, para diferentes condições de clima e solo, este trabalho teve como objetivo avaliar o nível de compatibilidade e pegamento na enxertia da cultivar Thompson Seedless sobre 10 tipos de porta-enxertos, visando ampliar a gama de variedades disponíveis, com bons resultados na enxertia de mesa

Base de dados geoespaciais do projeto Geosaltus.

Este trabalho objetiva apresentar a primeira versão da base de dados geoespaciais (BDG) do Projeto GeoSaltus (Classificação e Espacialização do Estoque de Carbono de Florestas Naturais e Plantadas por meio de Sensoriamento Remoto). Os sistemas florestais fazem parte de uma importante estratégia de uso da terra, voltada à manutenção da biodiversidade, aos serviços ambientais, à geração de produtos madeireiros e não madeireiros. Os fluxos de emissões de gases de efeito estufa e o carbono estocado nas florestas são informações imprescindíveis, e sua estimativa pode amparar políticas públicas de desenvolvimento e sustentabilidade. Esta base objetiva integrar dados geoespaciais provenientes de várias fontes e que permitam gerar informações e consultas entre os membros do projeto e demais usuários. Os diferentes planos de informações geográficas usados na geração da BDG foram definidos a partir de sua relevância para o desenvolvimento do projeto e foram divididos em: a) imagens de satélite/bases cartográficas, b) mapas temáticos e c) áreas de estudo. A consulta da BDG e de suas relações espaciais pode ser acessada por meio do webgis GeoSaltus (http://mapas.cnpm.embrapa.br/geosaltus/)

Deslocamento de DMUS pela fronteira de eficiência em modelos de Análise de Envoltória de Dados com ganhos de soma zero.

O trabalho apresenta uma extensão do modelo DEA com Ganhos de Soma Zero (DEA-GSZ) para os casos em que devido à redução de outputs (para que a soma seja constante), há a possibilidade ou a imposição de redução dos inputs utilizados. Nesses casos, não há o deslocamento da fronteira, mas sim o deslocamento das DMUs pela fronteira eficiente (ou pelas camadas de iso-eficiência). São apresentados os casos bidimensional e multidimensional. Para este, devido à complexidade dos algoritmos de determinação de faces do poliedro envolvente (fronteira DEA), é proposto o uso do modelo de suavização da fronteira, que representa a fronteira inteira por uma única equação polinomial
