1. Physicochemical characterization and comparison of labels of beef bouillon cubes
Abstract This study aimed at determining the centesimal composition, the energy value and the sodium content in beef bouillon cubes and compare them with the nutritional information by the manufacturer. Beef bouillon cube samples were collected in supermarkets in of the city of Limoeiro do Norte/CE, and the levels of nutrients were determined by official an

2. Espectroscopia 3D de núcleos ativos de galáxias: tratamento e análise de dados no óptico e infravermelho próximo / 3D spectroscopy of active galactic nuclei: treating and analysing data in the optical and near infrared.
Nesse trabalho, foi feito o tratamento e a análise de cubos de dados de 8 núcleos ativos de galáxias próximos, no óptico e no infravermelho. O tratamento e a análise de todos os cubos de dados foram feitos utilizando-se uma série de metodologias específicas, muitas das quais foram desenvolvidas nos últimos anos pelo grupo de trabalho do autor. A an�

3. XLDM: an xlink-based multidimensional metamodel
The growth of data available on the Internet and the improvement of ways to handle them consist of an important issue while designing a data model. In this context, XML provides the necessary formalism to establish a standard to represent and exchange data. Since the technologies of data warehouse are often used for data analysis, it is necessary to define a

4. Numerical study on hygroscopic material drying in packed bed
The paper addresses numerical simulation for the case of convective drying of hygroscopic material in a packed bed, analyzing agreement between the simulated and the corresponding experimental results. In the simulation model of unsteady simultaneous one-dimensional heat and mass transfer between gas phase and dried material, it is assumed that the gas-solid

5. Edge transformations for improving mesh quality of marching cubes
Marching Cubes is a popular choice for isosurface extraction from regular grids due to its simplicity, robustness, and efficiency. One of the key shortcomings of this approach is the quality of the resulting meshes, which tend to have many poorly shaped and degenerate triangles. This issue is often addressed through postprocessing operations such as smoothin

6. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

7. GEOMDQL: Uma Linguagem de Consulta geogrÃfica e Multidimensional
There have been a number of proposals in the literature aimed at integrating functionality and characteristics related to analytical (OLAP - Online Analytical Processing) and geographic (GIS- Geographic Information Systems) data processing. The main goal is to provide a unique environment with geographicmultidimensional processing capabilities in order to pr

8. Avaliação de embalagens flexiveis esterilizaveis e alimentos de pronto consumo para equipagens de aeronaves e para uso terrestre. / Evaluation of retortable pouch and foods of ready consumption for equipages of aircraft and terrestrial use.
The operational meals means are fundamental to the implementation of the activities of training and actual deployment of the armed forces around the world and is still employed in circumstances of contingency of civil order. In this sense, the Brazilian Air Force, in the search for solutions and continuing improvements in the area of the food supply, is prio

9. Estudo do escoamento atmosférico no Centro de Lançamento de Alcântara (CLA) através de medidas de torre anemométrica e em túnel de vento
The atmospheric flow at the Alcantara Launching Center (CLA), which is localized near a 50 m cliff, was studied through (i) the analysis of wind data that were measured during the periods from 1995 to 1999 (base years) and from 2004 to 2005 (for validation), at six levels of a 70 m anemometric tower (TA), which is placed 200 m downwind of the cliff, near a r

10. Fotografia e cubos : o fotográfico e o minimalismo
Most of the theories related to the photographic image have treated photography as an object of conventional research. The search for the specificity of the media was the tonic of the most important debates. In 1990, releasing a compilation entitled The photographic, the theoretic and historian of the art Rosalind Krauss observes that authors like Walter Ben
