Journal Article
TL;DR: Palavras-chave as mentioned in this paper presented a methodology to obtain analytical solutions of the vibrational states of the molecule of Hydrochloric Acid and first excited electronic state of molecular iodine from the analysis of resonance Raman spectra.
Abstract: O presente trabalho apresenta uma metodologia para obtencao de solucoes analiticas dos estados vibracionais da molecula de Acido Cloridrico e primeiro estado eletronico excitado da molecula de Iodo a partir da analise de espectros Raman ressonante O modelo do oscilador de Morse quântico e aplicado para representar os potenciais de interacao internucleares, permitindo o calculo de valores relativamente precisos para os parâmetros vibracionais comparados aos dados experimentais disponiveis na literatura Propriedades harmonicas e anarmonicas presentes nos espectros vibracionais das moleculas tambem sao discutidos Palavras-chave: oscilador de Morse; espectroscopia Raman; parâmetros vibracionais This paper presents a methodology to obtain analytical solutions of the vibrational states of the molecule of Hydrochloric Acid and first excited electronic state of molecular iodine from the analysis of resonance Raman spectra The model of the quantum Morse oscillator is applied to represent the inter-nuclear distance potential of interaction, allowing the calculation of relatively precise values for the experimental data vibrational parameters compared to available in literature Properties present in the harmonic and anharmonic vibrational spectra of molecules are also discussed Keywords: Morse oscillator, Raman spectroscopy, vibrational parameters

Journal Article
TL;DR: Palavras-chave et al. as mentioned in this paper analyzed the production conveyed of the national magazine Leitura: teoria e pratica (Reading: theory and practice) in the period of 2007 to 2009 focusing the authorship of the productions, working title and type.
Abstract: A pesquisa objetivou analisar a producao veiculada na revista nacional Leitura: teoria e pratica no periodo de 2007 a 2009 focando a autoria das producoes, titulo e tipo de trabalho. Os resultados demonstraram que quanto a genero dos autores nos 53 trabalhos estudados predominou a autoria feminina e unica (χ 2 o =3,93 e χ 2 c =3,84); quanto ao vinculo as IES Estaduais apresentam uma quantidade estatisticamente superior de artigos (χ 2 o =22,57 e χ 2 c =5,99, ≤0,05); quanto ao titulo houve diferenca estatistica, com prioridade para um menor numero de vocabulo (χ 2 o = 7,39 e χ 2 c = 5,99, ≤0,05); predominam os textos teoricos (χ 2 o =13,75 e χ 2 c =3,84, ≤0,05). A pesquisa permitiu concluir que com o ascendente crescimento de publicacoes em torno dessa tematica e importante e pertinente serem feitos estudos de metanalise na area de leitura. Palavras-chave: cientometria; avaliacao de producao; metanalise. This research aimed to analyses the production conveyed of the national magazine Leitura: teoria e pratica (Reading: theory and practice) in the period of 2007 to 2009 focusing the authorship of the productions, working title and type. The results evidenced that gender of authors in 53 works studied single and female authorship predominated ( χ 2 o =3,93 and χ 2 c =3,84); The state schools showed a statistically quantity top of articles ( χ 2 o =22,57 and χ 2 c =5,99, ≤0,05); there was statistical difference in the title, with priority for a smaller number of word ( χ 2 o = 7,39 and χ 2 c = 5,99, ≤0,05); there were predominance of theoretical texts ( χ 2 o =13,75 and χ 2 c =3,84, ≤0,05). The research showed that with the ascendant growth of publications around that issue is important and relevant meta-analysis studies in reading area. Keywords: Scientometrics; production evaluation; meta-analysis.
