1. LEARNING ABOUT EDGE EFFECTS AND ULTRAMICROELECTRODES IN ELECTROCHEMISTRY: SYNERGY BETWEEN EXPERIMENTS AND SIMULATIONS
A short experimental activity aimed at upper level undergraduate students or beginner researchers is presented to introduce the concepts of edge effects and hemispherical diffusion at ultramicroelectrodes. Students will perform simple cyclic voltammetry experiments varying the scan rate and using disk electrodes with different radii. They are then asked to i

2. Modeling non-ideal velocity of detonation in rock blasting
Abstract The performance of commercial explosives is an important subject in rock blast ing modeling and simulation. As a result of its non-ideal behavior, these explosives usu ally react below their ideal detonation velocity. In these cases, the multi-dimensional effects, heterogeneities and confinement conditions become important for properly quantifying t

4. Anesthesia upstream of the alcoholic lesion point alleviates the pain of alcohol neurolysis for intercostal neuralgia: a prospective randomized clinical trial
OBJECTIVES: Alcohol for intercostal neuralgia may induce severe injection pain. Although nerve block provided partial pain relief, alcohol might be diluted, and the curative effect decreased when the local anesthetic and alcohol were given at the same point. Therefore, we observed the modified method for intercostal neuralgia, a Two-point method, in which t

5. Classificação de fragmentos florestais urbanos com base em métricas da paisagem
Resumo A urbanização no município de Campinas-SP e região ocorreu de forma rápida e intensa, provocando acentuadas alterações na paisagem e resultando em uma expressiva degradação das áreas florestais e da cobertura vegetal natural. Este fenômeno deu origem a um processo de fragmentação florestal bastante intenso. Neste contexto, mapear estes fr

6. EDGE EFFECT ON CHEMICAL ATTRIBUTES OF SOIL IN A SEASONAL FOREST
RESUMO A magnitude das alterações em atributos do solo pode ser utilizada para identificar efeitos de interferências naturais ou antrópicas em fragmentos florestais. Este trabalho objetivou avaliar atributos químicos do solo como indicadores de efeito de borda em fragmento de Floresta Estacional Semidecidual, no Sudoeste da Bahia. Foram definidas quatro

7. Estágio sucessional de uma floresta estacional semidecidual secundária com distintos históricos de uso do solo no sul do Espírito Santo
Resumo Estudos sobre a estrutura vegetacional de fragmentos florestais que consideram o uso pretérito do solo podem contribuir para subsidiar ações conservacionistas e de restauração florestal. A partir disso, objetivamos comparar três sítios de um fragmento florestal com distintas histórias de perturbação e verificar se os mesmos diferem entre si

8. Effects of Bio-Inspired Surface Roughness on a Swept Back Tapered NACA 4412 Wing
ABSTRACT: This paper presents the overall pros and cons of the effect of surface roughness elements over a NACA 4412 tapered, swept back half wing with a sweep angle of 30º and a dihedral angle of 5º. The tests were conducted at a Reynolds number of 4 × 105 in the IIUM Low Speed wind tunnel. Different roughness sizes and roughness locations were tested fo

9. Vibration analysis of laminated functionally graded shallow shells with clamped cutout of the complex form by the Ritz method and the R-functions theory
Abstract The R-functions theory and Ritz approach are applied for analysis of free vibrations of laminated functionally graded shallow shells with different types of curvatures and complex planforms. Shallow shells are considered as sandwich shells of different types: a) face sheets of the shallow shells are made of a functionally graded material (FGM) and t

10. Identification and management of inverted or everted edges of traumatic tympanic membrane perforations
Resumo Introdução: A maioria das perfurações de membrana timpânica traumáticas apresenta bordas invertidas ou evertidas; no entanto, os efeitos dessas configurações sobre a cicatrização espontânea do tímpano continuam a ser uma questão controversa. Objetivo: Investigar a influência de bordas invertidas ou evertidas sobre a cicatrização espo

11. Finite element evaluation of the effects of curvature in Lamb waves for composites structural health monitoring
Abstract This work presents the effect of the high curvature to thickness ratio on the characteristics of Lamb Waves propagating over the skins of composite structures. It is accessed how the curvature on composite skins affects the group velocity of the symmetrical (S0) and asymmetrical (A0) wave modes. It is also accessed the gradient of curvature effect,

12. Tree Responses to Soil and Edge Effects in a Semideciduous Forest Remnant
ABSTRACT The present study seeks to characterize the composition, structure, and functional traits of the tree stratum of a Semideciduous Forest in Pouso Alegre, MG, Brazil (22º12’43”S and 45º59’30”W), by comparing Edge and Interior habitats and their relation to human impacts and soil variables. The tree community (diameter at 1.3 m (DBH) higher
