Factors associated with fruit and vegetable intake among adults of the city of São Paulo, Southeastern Brazil

OBJETIVO: Descrever a freqüência de consumo de frutas, legumes e verduras por adultos e analisar os fatores associados ao seu consumo. MÉTODOS: Estudo transversal realizado entre outubro e dezembro de 2003 no município de São Paulo (SP). Foram realizadas entrevistas telefônicas em amostra probabilística da população adulta (>18 anos) residente em domicílios servidos por linhas fixas de telefone, totalizando 1.267 mulheres e 855 homens. A freqüência do consumo de frutas, legumes e verduras foi medida por meio de um roteiro com perguntas curtas e simples. Na avaliação dos fatores associados ao consumo, realizou-se análise de regressão linear multivariada e hierarquizada, com variáveis sociodemográficas no primeiro nível hierárquico, comportamentais no segundo e relacionadas ao padrão alimentar no terceiro nível. RESULTADOS: A freqüência de consumo de frutas, legumes e verduras foi maior entre as mulheres. Para ambos os sexos, verificou-se que a freqüência desse consumo aumentava de acordo com a idade e a escolaridade do indivíduo. Entre mulheres que relataram ter realizado dieta no ano anterior houve maior consumo de frutas, legumes e verduras. O consumo de alimentos que indicam um padrão de consumo não saudável como açúcares e gorduras se mostrou inversamente associado ao consumo de frutas, legumes e verduras em ambos os sexos. CONCLUSÕES: O consumo de frutas, legumes e verduras da população adulta residente em São Paulo foi maior entre as mulheres, sendo influenciado pela idade, escolaridade e dietaOBJECTIVE: To describe the frequency of fruit and vegetable intake by adults and to assess factors associated with this frequency. METHODS: Cross-sectional study, carried out between October and December 2003 in the municipality of São Paulo, Southeastern Brazil. Telephone interviews were conducted on a probabilistic sample of the adult population (>18 years) living in the city of Sao Paulo and with access to land telephone lines, totaling 1,267 women and 855 men. Frequency of fruit and vegetable intake was obtained by means of a questionnaire containing short, simple questions. Association of different factors with fruit and vegetable intake was assessed by multivariate linear regression using a hierarchic model with sociodemographic variables in the first hierarchical level, behavioral variables in the second, and diet-related variables in the third. RESULTS: Frequency of fruit and vegetable intake was higher among women. For both sexes, frequency of intake increased with age and schooling. Intake was also higher among women who reported having been on a diet during the last year. Consumption of foods indicative of an unhealthy diet - such as sugars and fats - was inversely associated with fruit and vegetable intake among subjects of both sexes. CONCLUSIONS: Fruit and vegetable intake in the adult population of Sao Paulo was higher among women, and was influenced by age, schooling, and die

A apresentação de propostas, no mesmo procedimento de contratação pública, por empresas em relação de grupo ou de domínio

A presente dissertação tem por objecto analisar a problemática da participação simultânea, no mesmo procedimento de contratação pública, de operadores económicos que se encontram interligados por relações societárias, nomeadamente, por relações de domínio ou de grupo. A análise deste tema será realizada, maioritariamente, à luz do Direito da Concorrência e do Direito da Contratação Pública. Esta análise tem como ponto de partida aquela que tem sido a jurisprudência do Tribunal de Justiça da União Europeia sobre o tema e a sua influência na jurisprudência dos tribunais nacionais. A partir do estudo da jurisprudência e da legislação nacional e europeia, analisar-se-á o impacto da participação simultânea daqueles operadores económicos nos procedimentos de contratação pública, bem como a possibilidade de proceder à sua exclusão em alguns desses procedimentos, nomeadamente, quando dali resulte uma subversão do funcionamento e dos objectivos próprios de determinado procedimento.The main goal of this dissertation is to analyze the problem of the simultaneous participation of related undertakings, namely, when they are in a group or controling relationship, in the same public procurement procedure. The analysis of this theme will be carried out based on Competition Law and Public Procurement Law. The starting point of this study is the analysis of the European Court of Justicecase l aw and its influence on national courts case law. From the study of european and nacional case law and legislation, we will analyse the impact of the simultaneous participation of those economic operators in the public procurement procedures, as well as the possibility of excluding them in some of these procedures, in particular, when its adversely affect the procedure

Platinum nanoparticles stabilized by N-heterocyclic thiones. Synthesis and catalytic activity in mono- and di-hydroboration of alkynes

N-Heterocyclic Thiones (NHT) proved to be efficient ligands for the stabilization of small platinum nanoparticles (1.3-1.7 nm), synthesized by decomposition of [Pt(dba)2], under a H2 atmosphere, in the presence of variable sub-stoichiometric amounts of the NHT. Full characterization by means of TEM, HR-TEM, NMR, ICP, TGA and XPS have been carried out, providing information about the nature of the metal nanoparticles and the interaction of the NHT ligands to the metal surface. Importantly, DFT calculations indicate that some NHT ligands interact with the metal through the C[double bond, length as m-dash]C double bond of the imidazole fragment in addition to the sulfur atom, thus providing additional stabilization to the nanoparticles. According to XPS, TGA and ICP techniques, the surface coverage by the ligand increases by decreasing the size of the substituents on the nitrogen atom. The platinum nanoparticles have been used as catalyst in the hydroboration of alkynes. The most active system is that with a less covered surface area lacking an interaction of the ligand by means of the C[double bond, length as m-dash]C double bond. This catalyst hydroborates alkynes with excellent selectivities towards the monoborylated anti-Markovnikov product (vinyl-boronate) when one equiv. of borane is used. Very interestingly, aliphatic alkynes undergo a second hydroborylation process leading to the corresponding 1,1- and 1,2-diboroylated species with good selectivities towards the former.España MINECO (Projects CTQ2016-76267-P, CTQ2016-80814-R and CTQ2016- 81797-REDC)España Junta de Andalucía Project FQM-212

Migration velocity analysis using residual diffraction moveout: a real-data example

CAPES - COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIORCNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOUnfocused seismic diffraction events carry direct information about errors in the migration-velocity model. The residual-diffraction-moveout (RDM) migration-velocity-analysis (MVA) method is a recent technique that extracts this information by means of adjusting ellipses or hyperbolas to uncollapsed migrated diffractions. In this paper, we apply this method, which has been tested so far only on synthetic data, to a real data set from the Viking Graben. After application of a plane-wave-destruction (PWD) filter to attenuate the reflected energy, the diffractions in the real data become interpretable and can be used for the RDM method. Our analysis demonstrates that the reflections need not be completely removed for this purpose. Beyond the need to identify and select diffraction events in post-stack migrated sections in the depth domain, the method has a very low computational cost and processing time. To reach an acceptable velocity model of comparable quality as one obtained with common-midpoint (CMP) processing, only two iterations were necessary.Unfocused seismic diffraction events carry direct information about errors in the migration-velocity model.

Effect of noise exposure on hearing of pavilion athletes

Background, Traditionally, hearing is divided into peripheral (how much we listen) and central (as we hear - quality). Exaggerated exposure to noise in reverberant environment can have negative effects on how much we hear but on the discrimination capacity and auditory memory of the word its effects can be positive. Pavilion athletes are subject to constant noise in a closed and reverberant environment, are a good example to ascertain the impact of noise on hearing. The present study aims to understand the effects of noise exposure on hearing athletes (training 3 to 4 times a week), comparing the results with the results of a matched non-sports control group in age and sex. Material and Methods, For the study, the sample consisted of 32 individuals, 16 non-athletes and 16 athletes of pavilion, aged between 18 and 25 years. A simple tonal audiogram was performed by air, a repetition test of words, in the silence and with noise and a test of repetition of pseudo words in the silence and with noise. Results, In the simple tonal audiogram, only in the right ear in the frequencies of 1000 and 10000 Hz, we found statistically significant differences, with worse thresholds in the athletes group. In the repetition tests of words and pseudo words, the performance of athletes was better, both in silence and in noise, with statistically significant differences in word repetition in silence and repetition of pseudo words in noise. Conclusion, The need for verbal communication in a noisy and reverberant environment, evidenced during a sports training in pavilion, trains the abilities to discriminate and memorize the word heard in noise, having a positive impact on these abilities of the central auditory nervous system.info:eu-repo/semantics/publishedVersio
