this study was aimed to investigate the effects of environmental pollution with heavy metals from ferro-nickel smelter on aminolevulinic acid dehydratase (alad) activity, and to analyze the blood lead level of feral pigeon ( columba livia ) in ferro-nickel smelter courtyard in drenas city, republic of kosovo. for this purpose, twenty specimens of feral pigeon (20 birds, males and females), were...

Here we present a novel and extremely simple method that can manipulate magnetic label-free nanoliter water-drops using micro-nanoliter magnetically controlled hydrophobic ferro-drops used as magnetic mediators. Water-drops and ferro-drops can be dynamically connected under interface force of water/oil, allowing water-drops to be rapidly motioned on threedimensional open platforms and transferr...

Magnetite (Fe304) nanoparticles stabilised by sulfonatocalixarene macrocycles are readily accessible by a rapid in situ co-precipitation, and exhibit ferro-fluidic and superparamagnetic behaviour.

We discovered ferromanganese nodules that measure up to 46 cm in diameter with stromatolitic growth patterns in the western central near-shore portion of Second Connecticut Lake, Pittsburg, New Hampshire. They occur as four distinct morphotypes: irregular laminated convex plates that form concentric rings around a nucleating center ("domed-plate"), continuous pustular pavements that extend >10 ...

OBJECTIVE To determine the relationship between biomarkers of exposure, disease and susceptibility, and early health effects and long-term diseases related to occupational manganese (Mn) exposure. DESIGN Baseline survey of a longitudinal cohort study of workers in a ferromanganese refinery. PARTICIPANTS A total of 1888 individuals (1197 men, 691 women; average seniority 15.34 years) were en...

A questão ambiental tem sido motivo de ampla discussão em nível nacional e internacional, face à exploração desenfreada dos recursos naturais enorme geração resíduos por parte da indústria. reciclagem sólidos é uma das formas atenuar o proble- ma, reduzindo, conseguinte, impacto ambiental. Esta pesquisa objetivou caracterizar a escória ferro-cromo como agregado graúdo para produção concreto. Os...
