1. The circadian timing of noise exposure influences noise-induced inflammatory responses in the mouse cochlea
Abstract Introduction: Noise-induced hearing loss is one of the most common forms of sensorineural hearing loss. Nevertheless, the mechanisms of noise-induced hearing loss are still not fully understood. Objective: To investigate the dynamics of inflammatory responses in the mammalian cochlea following noise trauma at two different times, once during the l

2. Analysis of cracks and coating in iron ore pellets by digital image processing
Abstract The pelletizing process agglomerates ore fines previously considered as tailings and makes its application possible in the form of pellets. During the process, the pellets are subjected to various compressive forces and temperature changes, which cause ruptures in their surface. These ruptures (cracks) impair the performance of the pellets in the re

3. Impacto de la regla de decisión en el modelado de la difusión de innovaciones
Abstract In this, paper we analyze the impact of the decision rule to represent the behavior of individuals in the diffusion curve predicted by models of innovation diffusion at the individual level. We use an agent-based model, in which diffusion takes place in a small-world network, and analyze the phenomenon using 4 different decision rules: (1) threshold

4. Neurophysiological correlates of color vision: a model
The tree-receptor theory of human color vision accounts for color matching. A bottom-up, non-linear model combining cone signals in six types of cone-opponent cells in the lateral geniculate nucleus (LGN) of primates describes the phenomenological dimensions hue, color strength, and lightness/brightness. Hue shifts with light intensity (the Bezold-Brücke ph

5. Influência do alinhamento de nanotubos de carbono nas propriedades elétricas de nanocompósitos de matriz epoxídica / Influence of the alignment of carbon nanotubes in the electrical properties of epoxy matrix nanocomposites
Epoxy resin / carbon nanotubes (CN) composites are widely used due to the versatile matrix phase and the excellent properties of the reinforcing phase. However, the development of polymer nanocomposites still faces three important challenges: interfacial interaction, dispersion and orientation of the reinforcing phase. This work studied the orientation proce

6. A INDIVIDUAÇÃO COMO FENÔMENO ESTÉTICO: ARTE, CORPO E LINGUAGEM NO JOVEM NIETZSCHE / THE INDIVIDUATION AS AESTHETIC PHENOMENON: ART, BODY AND LANGUAGE IN THE YOUNG NIETZSCHE
This study focuses on Nietzsche`s thinking of youth and the context in which it is inserted. Our general aim consists in indicating the fundamental points to The birth of tragedy`s comprehension, his very first published work, as well as the philosophical influences of that time in Germany. The specific aim consists in understanding how his theory could be p

7. Truques sensoriais em diferentes tipos de distonia e no espasmo hemifacial
Introduction: The dystonia is a syndrome of sustained involuntary muscle contractions always producing twisting and repetitive movements or abnormal postures. Of all movement disorders associated with basal ganglia dysfunction, dystonia is the least understood in terms of underlying pathophysiology. Recent works revealed that basal ganglia cortico-striatal-t

8. A interdisciplinaridade do meio ambiente : da geografia ao direito ambiental
The present work promotes an discussion on the interdisciplinarity of the environment, traversing for the optics of geographic science until its protection in framework legal. To gain its objectives contextualizes in elapsing of the times the intrinsic dichotomy relation of the man and the nature, being searched to explicit the socioeconomic, cultural transf

9. Modelo para determinação do grau de globalização da empresa / Model for determining the degree of globalization the company
The globalization is a phenomenon that affects all sorts of organizations, such organizations have different levels of international involvement. To test any theory that considers internationalization as an independent variable one need a reliable instrument to measure the relative globalization of companies. Based on a sample of the worlds 100 largest multi

12. Bone conduction measurements in normal hearing subjects: acoustic radiation and bone vibrator positioning / Medida da condução óssea em sujeitos ouvintes normais: radiação acústica e posicionamento do vibrador ósseo
Clinical audiology literature and practice raise questions about bone conduction assessment results. The most common questions are related to the reliability of bone conduction thresholds as they suffer a lot of artifacts that may mislead the results obtained. Silman &Silverman (1997) describe two important factors that could interfere in such measurement: a
