1. Topographic modelling using UAVs compared with traditional survey methods in mining
Abstract The current developments with unmanned aerial vehicles (‘UAVs’) are revolutionizing many fields in civil applications, such as agriculture, environmental and visual inspections. The mining industry can also benefit from UAVs in many aspects, and the reconciliation through topographic control is an example. In comparison with traditional topograp

2. AplicaÃÃo de princÃpios de qualidade de dados durante o desenvolvimento de um sistema computacional mÃdico para a cirurgia coloproctolÃgica / Application of data quality principles in the development of a computacional medical system for coloproctology surgery
Lately, many human knowledge fields use computer systems to support data management which are the foundation to the decision making process. Data Quality (DQ) is a key feature whose absence can undermine the usefulness of the information and the processes that use it. There can be found in the literature several cases of DQ problems with impact in many

3. Mecanismos intraflagelares de transporte e trânsito de proteínas: uma abordagem pós-genômica e computacional de caracterização da virulência flagelar em Leishmania spp. / Intraflagelares mechanisms of transport and transit proteins: a post-genomics and computational characterization of virulence flagellar Leishmania spp.
Leishmania are flagellated protozoa that cause a main neglected diseasease, collectively known as leishmaniases, posing a constant challenge for the control and prevention of the disease due to the wide-world distribution and prevalence of these parasites. As an insinuating pathogen, Leishmania has a specialized organelle for motility, the flagellum, which i

4. O impacto do tipo de amostragem no controle de qualidade na lavra = Influence of the sampling method on grade control
Um dos grandes desafi os enfrentados pela indústria mineral é a difi culdade em prover à usina de benefi ciamento minérios que possuam as especifi cações de teores adequadas para seu bom desempenho. O conhecimento geológico das diferentes litologias que formam uma jazida é etapa fundamental para a garantia da qualidade esperada do minério, mas não

6. Efeitos do acetato de chumbo em tecido ósseo de ratos
Lead is a ubiquitous pollutant in the environmental ecosystem which distribution is mainly anthropogenic, come from burning fossil fuels, mining and various industrial products. There is little knowledge of the involvement of this element on the bone metabolism. This study aimed to determine possible changes in adult rat bone, contaminated with lead acetate

7. PREDIÇÃO DO POTENCIAL DE DRENAGEM ÁCIDA DE MINAS UTILIZANDO O MÉTODO CINÉTICO DA COLUNA DE LIXIVIAÇÃO / POTENTIAL PREDICTION OF ACID MINE DRAINAGE EMPLOYING LEACHING COLUMN KINETIC METHOD
The acid rock mine drainage (ARD) arising from sulfides oxidation in mining areas is a serious environmental problem that markedly affects the quality of the surrounding water. Choosing the measure for remediation and/or preventing pollution effect depends on a suitable evaluation through a prediction program, it has principally tests of the acid generation

8. A Mineração de Brita na Região Metropolitana do Rio de Janeiro
The crushed stone mining directly supplies the raw material used in civil construction, making possible the execution of basic infrastructure, construction and paving works in general, playing a fundamental role in the urban development. Such development along with the necessity of the supplier-consumer proximity has approximated the population and the miner

9. Some factors influencing interobserver variation in classifying simple pneumoconiosis.
Three experienced physician readers assessed the chest radiographs of 743 men from a coal mining community in West Virginia for the signs of simple pneumoconiosis, using the ILO U/C 1971 Classification of Radiographs of the Pneumoconioses. The number of films categorised by each reader as showing evidence of simple pneumoconiosis varied from 63 (8.5%) to 114
