1. On the classification and treatment of outliers in a spatial context: A Bayesian Updating approach
Abstract Checking and treating extreme values is commonplace in modelling workflows. The main methods to manage outliers may be categorized into graphical, Kriging- and simulation-based approaches. While graphical methods usually classify outliers from a global perspective, geostatistical methods evaluate outliers in a local context. Ordinary-Kriging based a

3. Assessment of anesthetic properties and pain during needleless jet injection anesthesia: a randomized clinical trial
Abstract Pain due to administration of local anesthetics is the primary reason for patients' fear and anxiety, and various methods are used to minimize it. This study aimed to measure the degree of pain during administration of anesthesia and determine the latency time and duration of pulpal anesthesia using two anesthetic methods in the maxilla.

4. Resposta do clima amazônico ao desmatamento progressivo da Amazônia e do Cerrado / Response of the Amazonian climate to progressive deforestation of the Amazon and Cerrado
There is a clear shift happening in the physical environment of the Amazon forest, where human intervention has intensified dramatically during the last half of the twentieth century. Recent studies suggest that changes in regional climate caused by local deforestation have the potential to cause parts of the Amazon to cross an ecological tipping point: a cr

5. Efeito local e sistêmico do laser de baixa potência (830nm) no limiar de dor por pressão em indivíduos saudáveis: estudo prospectivo, controlado, randomizado / Local and systemic effect of low power laser (830nm) in the pressure pain threshold in healthy subjects: a prospective, controlled, randomized
Introdução: O laser de baixa potência (LBP) é utilizado como recurso terapêutico para controle da dor. Porém, ainda é questionado o seu real efeito como também a dosimetria mais eficaz para esse efeito analgésico. Objetivo: Avaliar o efeito local e sistêmico do LBP no limiar de dor por pressão em indivíduos saudáveis. Materiais e Métodos: 150 i

6. Participation of cannabinoid receptors in peripheral nociception induced by some NSAIDs
Nonsteroidal anti-inflammatory drugs (NSAIDs) have been used extensively to control inflammatory pain. Several peripheral antinociceptive mechanisms have been described, such as opioid system and NO/cGMP/KATP pathway activation. There is evidence that the cannabinoid system can also contribute to the in vivo pharmacological effects of ibuprofen and indometha

7. Effect of the 5-HT4 receptor and serotonin transporter on visceral hypersensitivity in rats
Visceral hypersensitivity plays an important role in motor and sensory abnormalities associated with irritable bowel syndrome, but the underlying mechanisms are not fully understood. The present study was designed to evaluate the expression of the 5-HT4 receptor and the serotonin transporter (SERT) as well as their roles in chronic visceral hypersensitivity

8. Percutaneous sciatic nerve block with tramadol induces analgesia and motor blockade in two animal pain models
Local anesthetic efficacy of tramadol has been reported following intradermal application. Our aim was to investigate the effect of perineural tramadol as the sole analgesic in two pain models. Male Wistar rats (280-380 g; N = 5/group) were used in these experiments. A neurostimulation-guided sciatic nerve block was performed and 2% lidocaine or tramadol (1.

9. Processamento de sinais de descargas parciais em tempo real com base em wavelets e seleção de coeficientes adaptativa espacialmente
On-line partial discharge (PD) analysis is a highly pursued feature due to the economy related to scheduled shutdowns, disassembling and transport. Nevertheless, on-site PD measurements are frequently limited by interferences found in high-voltage facilities, a situation that imposes the continued development of PD signal processing methods. In the last year

10. Effect of electron inertial delay on Debye sheath formation
Present contribution deals with the role of weak but finite electron inertia on the sheath formation condition. As reported earlier this becomes effective when the ions' drift velocity exceeds the phase velocity of the acoustic wave fluctuations. Such situation has natural existence near the sheath edge. Keeping this in mind we have revisited the problem of

11. Marcadores metálicos como avaliação do impacto crônico de emissões petroquímicas em zona urbana
Nickel and vanadium were tested as tracers of oil refinery emission distribution in populated area of Rio Grande-RS. The anomalies of these elements in surface soil are considered a long-term reflection of the emissions in low atmosphere. The spatial distribution of Ni and V in the soil corresponded to the pattern of local winds. The threshold of 1.5 backgro

12. Monitoração e roteamento adaptativo para fluxos QoS em NoCs
O crescente número de aplicações executando em MPSoCs emergentes pode ser caracterizado pela sua alta demanda de computação e comunicação nas diferentes parte do chip. Os elementos de processamento que executam estas aplicações trazem uma natureza dinâmica e imprevisível para o tráfego em chip, devido à variabilidade nas taxas de injeção de da
