14. The NoBLOCK Technology A Major Breakthrough in Wet High Intensity Magnetic Separation (WHIMS)
Since its introduction in 1963 by G.H. “Jones”, WHIMS MS has proven to be, worldwide, a major technology for separating several types of ore fines from their contaminants. Unfortunately, despite its superb characteristics, even if the best operational procedures are followed, one main issue lasts. It is the blocking of the matrix gaps by oversized partic

15. APLICAÇÃO DE ÓXIDOS DE FERRO NANOESTRUTURADOS COMO ADSORVENTES E FOTOCATALISADORES NA REMOÇÃO DE POLUENTES DE ÁGUAS RESIDUAIS
New techniques for treating wastewater, particularly the removal or degradation of organic pollutants and heavy metals, among other pollutants, have been extensively studied. The use of nanostructured iron oxides as adsorbent and photocatalyst for the removal of these contaminants has proved a promising approach, not only because of their high treatment effi

16. Advances in Computed Tomography Evaluation of Skull Base Diseases
Introduction Computed tomography (CT) is a key component in the evaluation of skull base diseases. With its ability to clearly delineate the osseous anatomy, CT can provide not only important tips to diagnosis but also key information for surgical planning. Objectives The purpose of this article is to describe some of the main CT imaging features that c

17. Subsídios para implantação do processo de compostagem em município de pequeno porte : estudo de caso em Corumbataí-SP / Subsidies for the implementation of the composting process in a small municipality. Case study: Corumbataí-SP
University of São Carlos, 2012. Composting is one of the oldest processes of recycling organic waste. Despite being an environmentally appropriate treatment, their use is still little known regarding the management of municipal solid waste (MSW). This study aimed to investigate the management of MSW in Corumbataí - SP. For this purpose gravimetric characte

19. Análise de patentes de tecnologias relacionadas a resíduos de equipamentos elétricos e eletrônicos / Analysis of patents for technologies related to waste electrical and electronic equipment
The problem of solid waste has been touted as one of the most serious to date. The increasing scarcity of land for the establishment of new landfills, combined with the existing limitations for the recovery of non-renewable materials, low degree of implementation of new treatment alternatives and recycling, now represent a major challenge. Therefore, conside

20. Estudo de um novo conceito de coluna de destilação : coluna de destilação com integração interna de calor (CDIIC) / Study of a new concept of distillation column : heat integrated distillation column (HIDiC)
The separation processes are largely used in petroleum and alcohol-chemical industries. The distillation process represents around 40% of energy costs in industrial operation, thus large among of energy of the process is not used and it is lost to the surrounding. In Brazil, industrial developments and the need of energy market allowed innovations to the con

22. Enantiomeric distribution of key volatile components in Citrus essential oils
Citrus as many other plants present characteristic distribution of some enantiomers, thus it is often possible to use this parameter for identification, characterization, genuineness, and pharmacological activity assessment. In particular, it is possible to reveal adulteration of different nature, such as addition of synthetic compounds, or natural component

24. Caracterização de membranas de poliamida 66 preparadas pelo método de inversão de fases
In the present study, polyamide 66 (PA 66) membranes were prepared by phase inversion (PI) and characterized in order to verify their potential application in separation processes. PA 66 membranes were prepared using two different solvents, formic acid (FA) and chloridric acid (HCl), and water as a non-solvent. Membranes prepared in film form (not supported)
