1. Influence of the pH regulator on the dolomite hydrophobization process
Abstract A study was carried out to investigate the combined effect of released ions in the pulp by pH regulator and mineral surface on dolomite flotation. The tests were carried out using a dolomite sample in a bench flotation cell with automatic froth remover. Zeta potential measurements, solution conductivity and FTIR analysis were done to support the int

2. Modeling hourly air temperature based on internationally agreed times and the daily minimum temperature
RESUMO Existem áreas que exigem conhecimento da variação da temperatura do ar ao longo do dia, como previsão de doenças ou cálculo de horas de frio. Porém, nem sempre há estações meteorológicas automáticas próximas para observar esta variável. Nesse sentido, modelos que descrevem a variação temporal diária da temperatura do ar podem ser util

3. Automatic pain quantification using autonomic parameters
The objective measurement of subjective, multi-dimensionally experienced pain is a problem for which there has not been an adequate solution. Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals. Biopoten

4. A forced running wheel system with a microcontroller that provides high-intensity exercise training in an animal ischemic stroke model
We developed a forced non-electric-shock running wheel (FNESRW) system that provides rats with high-intensity exercise training using automatic exercise training patterns that are controlled by a microcontroller. The proposed system successfully makes a breakthrough in the traditional motorized running wheel to allow rats to perform high-intensity training a

6. Automatic hippocampus segmentation through similarity cloud / Segmentação da estrutura cerebral hipocampo por meio de nuvem de similaridade
The hippocampus is a particular structure that plays a main role in human memory systems. Tissue modifications of the hippocampus lead to neurodegenerative diseases as epilepsy, multiple sclerosis, and dementia, among others. To measure hippocampus atrophy, it is crucial to get its isolated representation from the whole brain volume. Separating the hippocamp

7. ANEMÔMETRO BASEADO EM SENSOR TERMO-RESISTIVO OPERANDO A TEMPERATURA CONSTANTE COM AJUSTE AUTOMÁTICO DE FAIXA DINÂMICA / ANEMOMETER SENSOR BASED ON OPERATING A TERMINATION-RESIST CONSTANT TEMPERATURE WITH AUTOMATIC ADJUSTMENT OF TRACK DYNAMICS
O anemômetro de fio quente, baseado em sensor termo-resistivo operando à temperatura constante, é uma arquitetura clássica que é vastamente encontrada na bibliografia. Todavia, esta arquitetura pode apresentar um problema devido à variação da faixa dinâmica de sua tensão de saída para variações significativas da temperatura do fluido. Neste trab

12. CO-SITE MICROSCOPY: NEW POSSIBILITIES IN THE ORE CHARACTERIZATION / MICROSCOPIA CO-LOCALIZADA: NOVAS POSSIBILIDADES NA CARACTERIZAÇÃO DE MINÉRIOS
Computer-controlled microscopes with digital image acquisition and analysis led to the creation of a new field, called Digital Microscopy. Digital Microscopy not only allows a certain degree of automation but also has brought new possibilities to microstructural characterization. One of these new and promising possibilities is Co- Site Microscopy, that links
