1. Development of innovation routes for iron ore using high intensity magnetic separators
Abstract The mineral processing of low-grade iron ores commonly generates large volumes of slime, which are disposed as tailings. Modern mining requires strives to eliminate the use of tailings dams in a maximum effort to increase metallurgical recovery, the security and reduction of the operational cost. This research aims for the recovery of iron contained

2. Identifying agriculture land acquisitions for alleviating future food security concerns
Abstract The total available land for food, fuel, or forests is finite, while land demand is increasing and expected to increase further in the coming decades; resulting in deterioration of food security. Therefore, the corporate world adopted a solution of acquiring international agricultural land. Consequently, the global demand for land has progressively

3. Photoacoustic-based thermal image formation and optimization using an evolutionary genetic algorithm
Abstract Introduction For improved efficiency and security in heat application during hyperthermia, it is important to monitor tissue temperature during treatments. Photoacoustic (PA) pressure wave amplitude has a temperature dependence given by the Gruenesein parameter. Consequently, changes in PA signal amplitude carry information about temperature varia

4. ARSÊNIO E ARROZ: TOXICIDADE, METABOLISMO E SEGURANÇA ALIMENTAR
Arsenic is considered a semimetal, and its wide distribution in the Earth's crust in different chemical forms, including organic and inorganic species, has a great deal of influence on the mechanisms of toxicity. Exposure to arsenic can be either through occupational practice (use of pesticides) or by the consumption of water and food containing the element.

5. Sistemas CDMA ópticos coerentes baseados em codificação de fase espectral / Coherent optical CDMA systems based on spectral phase coding
In this work we perform a comprehensive analysis of a spectral phase-encoded time spreading optical code division multiple access (SPECTS-OCDMA) system. Despite being a numerical study, efforts were concentrated on the investigation of more realistic scenarios using as much information as possible from implemented test-beds in laboratories. In this context,

7. Atividades antinociceptiva e antiinflamatÃria dos polissacarÃdeos sulfatados da alga marinha vermelha Gracilaria cornea J. Agardh / Antinociceptive and anti-inflammatory activities of sulfated polusaccharides from the red marine alga Gracilaria cornea J. Agardh (1852) in animals
Marine algae are natural sources of sulfated polysaccharides possessing several biological activities (anticoagulant, antithrombotic, antinociceptive, anti-inflammatory etc.) and that exhibit minimal toxicity and are considered of great interest to the pharmaceutical and food industries. This study aimed to evaluate the effects of sulfated polysaccharides to

8. Technological development of aqueous extracts from Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, (mulateiro) using factorial design
The aim of the present work is to characterize the vegetal raw material of the Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum., Rubiaceae, known as "mulateiro", and to evaluate the influence of extractive parameters for attainment of standardized aqueous extractive solutions. The physical-chemical characterization of the samples was performed using p
