Introdução Avaliação e monitoramento são práticas fundamentais para a gestão do investimento social público privado. Como todas as esferas da vida social, estão sujeitas à forças políticas, socioeconômicas, culturais que atravessam relações entre indivíduos, comunidades, organizações instituições. Esse é um dos pontos de partida publicação “+Avaliação – Desigualdadeâ...

To further investigate the Renner–Teller (RT) effect and barriers to linearity and dissociation in the simplest singlet carbene, we recorded fluorescence excitation spectra of bands involving the pure bending levels 20 with n = 0–9 and the combination states 1 1 02 n 0 with n = 1–8 and 2 n 03 1 0 with n = 0–5 in the à A00 ’ X̃ A0 system of CDF, in addition to some weak hot bands. The spectra wer...

Spectra of ã B1(n1n2n3)5(110) and (200) – X̃ A1(000) of SO2 and SO2 are obtained in a supersonic jet at a resolution 0.015 cm. The rotational structures are analyzed for both isotopic species to obtain precise rotational and spin constants. Two new bands at 27 032.222~1! and 27 515.41~1! cm arising from vibronic interaction separately with vibrational state ~110! and ~200! of ã B1 are assigned t...

The spectroscopy and photodissociation dynamics of the à P and B̃ S states of the CNN radical have been investigated by fast beam photofragment translational spectroscopy. Vibronic transitions located more than 1000 cm above the à 3P←X̃ S origin were found to predissociate. Photofragment yield spectra for the B̃ 3S2←X̃ S band between 40 800 and 45 460 cm display resolved vibrational progressions wi...

We report a theoretical investigation of the X (2)A" and à (2)A' electronic states of HSO/HOS. Three-dimensional potential energy surfaces for the X (2)A" and à (2)A' electronic states of HSO/HOS have been calculated ab initio by the core-valence MR-SDCI+Q/[aug-cc-pCVQZ(S,O),aug-cc-pVQZ(H)] method, and near-global potential energy surfaces have been constructed. These surfaces have been used, i...

Aims—To investigate the expression of á, â, and ã catenins in oropharyngeal and hypopharyngeal squamous cell carcinoma and their relations to each other, as well as to clinical data, tumour diVerentiation, and prognosis. Methods—Primary tumours for analysis were obtained from 138 patients diagnosed with squamous cell carcinoma of the oropharynx or hypopharynx between 1975 and 1998 in eastern Fi...

Fuzziness is not a priori an obvious concept and demands some explanation. “Fuzziness” is what Black (NF 1937) calls “vagueness” when he distinguishes it from “generality” and from “ambiguity.” Generalizing refers to the application of a symbol to a multiplicity of objects in the field of reference, ambiguity to the association of a finite number of alternative meanings having the same phonetic...

The formaldehyde molecule is an important model system for understanding dynamical processes in small polyatomic molecules. However, prior to this work, there have been no reports of a resonance-enhanced multiphoton ionization (REMPI) detection scheme for formaldehyde suitable for rovibrationally state-selective detection in molecular beam scattering experiments. Previously reported tunable REM...
