1. Virtual Reality simulator for dental anesthesia training in the inferior alveolar nerve block
Abstract Objectives This study shows the development and validation of a dental anesthesia-training simulator, specifically for the inferior alveolar nerve block (IANB). The system developed provides the tactile sensation of inserting a real needle in a human patient, using Virtual Reality (VR) techniques and a haptic device that can provide a perceived fo

2. Bone density: comparative evaluation of Hounsfield units in multislice and cone-beam computed tomography
The aim of this study was to evaluate the validity of the bone density value of potential implant sites in HU obtained by a specific cone-beam computed tomography (CBCT) device. In this study, the HU values obtained using a MSCT scanner were used as the gold standard. Twenty mandibles (40 potential implant sites) were scanned using an MSCT scanner (Somatom S

3. Avaliação comparativa dos coeficientes de Hounsfield entre a tomografia computadorizada de feixe cônico e tomografia multislice / Comparative evaluation of the coefficients of Hounsfield between cone computed tomography and multislice CT
The aim of this study was to compare the attenuation coefficients (Hounsfield Unit) in both cone-beam computed tomography (CT) and multislice CT images. The 40-channel CT scanner (SOMATOM Sensation 40 - Siemens) was used to obtain images (n=20) of macerated mandibles considering the following protocol: axial slices of 0.7 mm in thickness and an interval of 0

4. Discurso ecológico: a palavra e a fotografia no Protocolo de Kyoto / Ecological discourse: writing and photography in the Kyoto Protocol
Esta pesquisa teve como objetivo relacionar operações discursivas distintas a palavra e a imagem a partir de um recorte também duplo, o discurso ecológico constituído pelo Protocolo de Kyoto e as fotografias que se auto-designam como representações imagéticas do mesmo. O trabalho elabora relações, aproximando e diferenciando conceitos como formaç�

5. Do psicodiagnóstico à intervenção em adictos: contribuições do Rorschach e do atendimento clínico / From the psychodiagnosis to the intervention in addicted patients: Rorschach and clinical practice contributions
Previously studies with addicted patients have indicated that, although there is no stable and profound psychic structure, specific to dependency behaviors, some aspects are recurrent, with respect to these patients. Among them, we could emphasize these individuals incapability to think, reflect, postpone, as well as the substitution of these abilities by ac

6. AN ARCHITECTURE FOR PHOTOREALISTIC IMAGE SYNTHESIS BASED ON MONTE CARLO TECHNIQUES / UMA ARQUITETURA PARA SÍNTESE DE IMAGENS FOTORREALISTAS BASEADA EM TÉCNICAS DE MONTE CARLO
One of the main goals in computer graphics is to create photorealistic images, that is, images indistinguishable from the ones captured by a real camera, or, more ambitiously, images that cause the same sensation on the visual system of an observer looking directly at a scene. Applications include illumination design, architecture, virtual reality and the mo

7. Do complexo de vira-latas ao homem genial: o futebol como elemento constitutivo da identidade brasileira nas crônicas de Nelson Rodrigues, João Saldanha e Armando Nogueira
Soccer is an activity and a discourse that has for years individualized, identified and brought pride to Brazilians, giving them an identity and marking their place in the world. As an identity artifice, soccer is a human construction, demarcated in time and space. In the epistemological search for the representation of Brazil as the land of soccer, the chro

8. Estimativa da temperatura e do saldo de radiação à superfície terrestre em Maceió-AL utilizando imagens TM/LANDSAT 5
The considered work esteem, by means of data of multispectral images of the Landsat 5 - TM, vegetation indices, albedo, surface temperature surface and the balance of radiation of the city of Maceió relating them with the urban mesh. The city of Maceió, in last the 30 years, it had its intensified areal growth, that is, the substitution of green areas for

9. O varejo de moda na cidade de São Paulo (1910-1940): a democratização da moda e a inserção do consumo de baixa renda
During the 1st half of the 20th century São Paulo consolidated itself as an urban center in which an important textile industry grew and caused important social transformations - not only in the retail market but algo in women manners and fashion. Some characteristics of the fashion retail and the social clothing universe in São Paulo during this period ar

10. Mechanisms of static and dynamic stereopsis in foveal cortex of the rhesus monkey
1. The sensation of stereoscopic depth rests on the central neural processing of signals evoked by the two retinal images of a single object in space. It was our purpose in this study to investigate in the behaving monkey the binocular cortical mechanisms that might underlie the ability to recognize the relative position and motion of objects in three-dimens

11. Neural correlates of the emergence of consciousness of thirst
Thirst was induced by rapid i.v. infusion of hypertonic saline (0.51 M at 13.4 ml/min). Ten humans were neuroimaged by positron-emission tomography (PET) and four by functional MRI (fMRI). PET images were made 25 min after beginning infusion, when the sensation of thirst began to enter the stream of consciousness. The fMRI images were made when the maximum r
