1. Nanofibras eletrofiadas e suas aplicações: avanços na última década
In recent years there has been an increasing interest in the development of nanomaterials with improved properties compared to their counterparts at the micro- and macroscopic scale. In this context, nanofibers obtained by electrospinning technique are highly attractive due to the unique combination of high surface area/volume ratio, porosity, flexibility, m

2. Analysis of cracks and coating in iron ore pellets by digital image processing
Abstract The pelletizing process agglomerates ore fines previously considered as tailings and makes its application possible in the form of pellets. During the process, the pellets are subjected to various compressive forces and temperature changes, which cause ruptures in their surface. These ruptures (cracks) impair the performance of the pellets in the re

3. Microwave Assisted Ultra-Fast Method to Synthesize Carbonate-Phosphates, Na3MCO3PO4 (M = Mn, Fe, Co, Ni) - Relevant Materials Applied in Sodium-Ion Batteries
Although largely used in mobiles and electric vehicles applications, insertion batteries based on Li-ion technology are high-cost devices. These applications require high-performance energy storage systems with high-energy and high-power densities, which are better attained by Li-ion technology. However, stationary applications such as power plants and unint

5. HPGR as alternative to fused alumina comminution route: an assessment of circuit simplification potential
Abstract A considerable portion of energy consumption and, as a consequence, operational costs in mineral processing, is associated with comminution. High Pressure Grinding Rolls (HPGR) are appealing for their energy efficiency and resulting lower operating costs. This article evaluates this technology as an alternative to the conventional fused alumina comm

6. Pre-concentration potential evaluation for a silicate zinc ore by density and sensor-based sorting methods
Abstract Pre-concentration consists of the preliminary discarding of a fraction of the mineral processing plant feed which contains little or none of the mineral of interest, reducing the mass to be processed in downstream operations (e.g. milling, concentration and dewatering), as well as the capital and operational costs. In this context, this study invest

7. THE USE OF SIMULATION TO MODEL THE DISPATCH OF INBOUND CONTAINERS IN PORT TERMINALS
ABSTRACT This paper describes a study of the dispatch planning/scheduling process for inbound containers handled with a reach stacker. Client container pickup is scheduled at least one day in advance for one of six two-hour time windows (six five-container-high stacks per time window) on a given day. A buffer area is available for the containers to be moved

9. Canonical correlations among grapevine agronomic and processing characteristics
ABSTRACT. Canonical correlation analysis allows conclusions to be drawn about the occurrence and magnitude of associations between two groups of characteristics. This study estimated the magnitude of association and interdependence between two trait groups of clones of two varieties of Vitis vinifera grapes. The study was based on the mean data of eight char

11. Monitoring and risk assessment due to presence of heavy metals and pesticides in tea samples
Abstract Tea is one of the most consumed beverages after water, but unfortunately the application of pesticides and heavy metals in crops make it unsafe for use. This research was conducted to evaluate the risk of heavy metals and pesticides in samples of natural source tea (gardens) and different local market brands. High Performance Liquid Chromatography

12. Evaluating the Effects of Removing Fines from Particleboards Manufactured from Amazonian Wood Residue
ABSTRACT The aim of this research was to evaluate the effects of removing fines on the physical and mechanical properties of high-density particleboard produced by mechanical processing of Caryocar villosum (pequiá), Tachigali myrmecophyla (tachi-preto) and Hymenolobium excelsum (angelim-da-mata) Amazonian woods. The panels were produced with nominal densi
