The effective parameters that influence in situ cast ferroTic composites were investigated. Centrifugal casting of specimens was carried out using ceramic & metallic molds. OM, SEM and XRD techniques were used to examine the existence of flows in the specimens. Results show that the control of chemical composition, processing, cooling rate and heat treatment has a promising effect on the qual...
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...
Resonance Raman spectra of horseradish peroxidase (HRP) in the 200 to 600 cm" region were measured for the reduced and oxidized states and in the presence and absence of substrate, For the reconstituted HRP with a S4Fe-substituted heme, the Raman line of ferro HRP at 244 cm" was shifted to 246 cm" but all other modes remained unshifted. The amount of the frequency shift agreed with that observe...
Intorduction: It is necessary to notice the subjective well-being and satisfaction of human resources in organizations and lack of attention to them has deleterious effects on individual and organizational performance. Method: The present study is a mixed (qualitative and quantitative) research which used the Q approach to examine and explain managers’ mental patterns regarding Subjective We...

Abstract At the core of theoretical framework ferroelectric field-effect transistor (FeFET) is thermodynamic principle that one can determine equilibrium behavior (FERRO) systems using appropriate potential. In literature, it often implicitly assumed, without formal justification, Gibbs free energy potential and impact charge accumulation be neglected. this Article, we first formally demonstrat...
2014 The renormalization group techniques are applied, for the first time, to surface magnetism in bulk magnets, for all signs of surface and bulk coupling constants. The q-state Potts model is specifically focused upon, and an interesting q-evolution of the phase diagram is exhibited. In particular the Ising model (q = 2) presents a remarkable feature in the case of competing bulk-and surface ...
Uma ferro porfirina poli-clorada, Fe(PCl 8 )Cl, foi sintetizada e usada como catalisador em reações de oxidação de hidrocarbonetos por iodosilbenzeno e peróxido de hidrogênio, em solução e ancorado covalentemente na aminopropilsilica. Embora a Fe(PCl 8 )Cl tenha mostrado a mesma eficiência da ferro porfirina precursora, Fe(P)Cl, na epoxidação de alcenos, foi um catalisador mais eficiente na hid...
