1. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

2. Microbial activity and studies on excavated megalithic micaceous potsherds from Peninsular India
Abstract The abundantly available mica flakes were added in raw materials to manufacture pottery in Central Peninsular India during the early Iron Age (700-300 BCE) for storage and glittering. The micaceous potsherds from the excavated megalithic site of Nagpur were studied for their composition, manufacturing techniques, microstructural features, microbial

3. Single-Layered Paper-Based Microfluidic Devices Made by Paint-Spraying Technique with Great Barrier Resistance for Colorimetric Assays
The single-layered paint-spraying paper based microfluidic devices (sp-μPADs) have been for the first time integrated with the colorimetric assay. The polymethyl methacrylate (PMMA) board was applied as the mask instead of the iron mask, reducing the power requirement of the cutting machine. The paint was sprayed into the paper, which blocked the pores of t

4. Comparative analysis of citrus fruits for nutraceutical properties
Abstract Fruits and vegetables (F and V) are valuable for their micronutrients, but many F and V in diverse growth areas have not been scientifically validated for these components. The nutraceutical characteristics of the pulp of eight citrus fruits grown in Pakistan were, therefore, investigated. Expectedly, the fruits differed in moisture (86.9-88.9%), as

6. Reduction Behavior of Low Grade Iron Ore at Reducing Conditions Simulating Different Zones of Blast Furnace
Representative technological samples for Baharia iron ore are collected from El-Gedida iron ore mines at the western desert of Egypt. Baharia iron ore was fired at 1000ºC for 3 hours, then the green and fired samples was isothermally reduced by different ratios of H2/CO/CO2/N2 which closely represent the theoretical reduction conditions in different zones o

7. Partial characterization of ethanolic extract of Melipona beecheii propolis and in vitro evaluation of its antifungal activity
ABSTRACT The ethanolic extract of Melipona beecheii Bennett 1831, propolis from Yucatán Mexico was evaluated in vitro for the determination of its phenolic compound content, antioxidant capacity and antifungal activity. The results were compared against those of the ethanolic extract of Apis mellifera propolis. The total phenolic content, flavonoid content

8. Lipid profile and quality of meat from finishing pig supplemented with minerals
Abstract This study aimed evaluate the effects of the associated supplementation of: chromium more iron (CrFe), magnesium more selenium (MgSe) and the four minerals (CrFeMgSe) on the parameters related to the pork quality. Supplementation with MgSe reduced the ether extract of the meat and changed the fatty acids profile, increasing the poly-unsaturated, n-3

10. Evaluation of the antimicrobial and antioxidant activity of 7-hydroxy-4’, 6-dimethoxy-isoflavone and essential oil from Myroxylon peruiferum L.f
Abstract: This study evaluated the antibacterial, antifungal, and antioxidant effect of 7-hydroxy-4’,6-dimethoxy-isoflavone and essential oil of Myroxylon peruiferum. The compound was isolated and its structure elucidated by NMR. The chemical composition of essential oil determined by GC-MS analysis. To evaluation of antimicrobial activity, the Minimum Inh

11. Reduction of electric arc furnace dust pellets by mixture containing hydrogen
Abstract The large amount of dust generated in electric arc furnace aligned with its chemical composition makes this dust a potential source of iron in the direct reduction iron process. Thus, the aim of this research is to investigate the reduction of pellets produced with electric arc furnace dust using hydrogen as the reducing agent. The kinetic investiga

12. Microstructural, thermochemistry and mechanical evaluation of self-reducing pellets using electric arc furnace (EAF) dust containing zinc for Waelz process
ABSTRACT The increment of recycling of steel using electric arc furnace and the tendency to coat of steel products with zinc, in order to prevent corrosion, has increased the proportion of galvanized scrap used worldwide in the recent years. Approximately 10 to 20 Kg/t of cast steel is generated in casting arcs. These collected dusts electric arc furnace (EA
