O presente número constitui a segunda investida do Departamento de Educação (DEDU), relativa à Revista Sitientibus, no momento em que esse completa 19 anos existência. Ampliação quadro docente, maior demanda ensino graduação, implantação diversos núcleos pesquisa extensão, consolidação cursos pós-graduação – mestrado e doutorado por meio convênios interinstitucionais, tudo isso dando concretude...

We analyse the internal spatial wage and employment structures of the Czech Republic, Hungary, Poland, Slovakia and Slovenia, using regional data for 1996–2000. A new economic geography model predicts wage gradients and specialization patterns that are smoothly related to the regions’ relative market access. As an alternative, we formulate a ‘Comecon hypothesis’, according to which wages and se...

We report a new effect of gravitationally induced quantum mechanical phases in neutrino oscillations. In the neighborhood of a neutron star, gravitationally induced quantum mechanical phases are roughly 15% of their kinematical counterparts. When this information is coupled with the mass square differences implied by the existing neutrino–oscillation data we find that the ∗This work was done, i...

This paper provides an overview of methodologies used to analyze inter-regional income inequality, and a critical survey of empirical studies that deal with Russian regions. It discusses implications of the growth theory regarding dynamics of inter-economy income inequality. Methodologies for empirically analyzing income inequality are classified as the cross-section approach, time series appro...

The purpose of this study is to present an “environmental catalyst” possessing both thermocatalytic activity and visible-light activity for the decomposition of organic pollutants. Molecule-sized MnOx clusters are highly dispersed on the surface of TiO2 (anatase/rutile = 4/1 w/w, P-25, Degussa) by the chemisorption-calcination cycle technique using Mn(acac)3 complex as a precursor (MnOx/TiO2). ...

We also studied this relation more than 30 years ago in 60 pairs of maternal and cord blood, and showed such a relation; ours was one of the first published studies on this subject2. Calcium, phosphorus, and alkaline phosphate levels were also assayed, and were repeated in babies of about one month of age. Maternal and cord 25-OH-CC levels were found lowest in winter months when compared to mot...

(23S)-23,25-Dihydroxycholecalciferol was converted into at least five metabolites in kidney homogenates prepared from 1,25-dihydroxycholecalciferol-treated chickens. One of these has been positively identified as 23,25,26-trihydroxycholecalciferol by u.v.-absorbance analysis, mass spectrometry and chemical formation of derivatives. 23,25,26-Trihydroxycholecaciferol produces 25-hydroxycholecalci...
