2. Metal Distribution in the Environmental Compartments of Manguaba Lagoon (Alagoas State, Brazil)
The metal concentrations in water, sediments and mollusks (Tagelus plebeius) of the Manguaba Lagoon and the influence of humic substances from water and sediments in the distribution of these metals were investigated in this work. The mean metal concentrations in water were: Mg (89.0 ± 0.11), Ca (32.0 ± 0.10), Fe (0.97 ± 0.02), Mn (0.52 ± 0.01), Zn (0.33

7. Ediacaran emerald mineralization in Northeastern Brazil: the case of the Fazenda Bonfim Deposit
Abstract The Fazenda Bonfim emerald deposit lies within the Seridó Belt. It is a classic example of deposit formed through metasomatic interactions between Be-rich granite intrusions and Cr(± V)-rich mafic-ultramafic rocks. The setting of the emerald mineralization was built under strong strike-slip dynamics, which produced serpentinization and talcificati

8. Regional Concentration of The Gross Production Value of Firewood in Paraíba
ABSTRACT This study analyzed the regional concentration of the gross production value (GPV) of firewood in Paraíba from 1994 to 2014. It measured the concentration by means of the Concentration Ratio [CR(k)] of the Herfindahl-Hirschman Index (HHI), Theil’s Entropy (E), the Hall-Tindelman Index (HTI), and the Gini Index (G). From the analyses performed, it

9. Characterization of Impact Toughness Properties of DIN39MnCrB6-2 Steel Grade
Boron added steels in quenched and tempered condition have been widely used in applications where good mechanical properties and low cost are required. In this study, impact resistance of DIN 39MnCrB6-2 steel grade was investigated due to its criticality in automotive components. Metastable phase diagrams were built to guide heat treatments. The influence he

10. A Low-Cost Video-Based Reflectometer for Selective Detection of Cu2+ Using Paper-Based Colorimetric Sensors
This paper presents a low-cost reflectometer for selective detection of Cu2+. The reflectometer is based on an emission light source using five light-emitting diodes at different wavelengths and a detector using a webcam. The samples were prepared using a filter paper-based colorimetric sensor with ascorbic acid-based quinoxaline derivative. Video analysis u

12. Mineral element and heavy metal (cadmium, lead and arsenic) levels of bee pollen in Turkey
Abstract In this study, mineral element and heavy metal levels in bee pollen produced in various regions of Turkey (20 samples) and imported bee pollen (4 samples), were determined using an Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) device. Mineral and heavy metal levels of bee pollens produced in Turkey were determined to be within t
