A partir dos dados extraídos do Corpus Tibullianum, e submetidos a tratamento estatístico, os autores pretendem reforçar a opinião geralmente aceita de que a obra não foi composta por um único poeta, admitindo a pluralidade de autores. Para tanto, utilizam, a distribuição de Waring e os índices mais recentes de riqueza lexical, apontando, entre as duas partes em que dividiram o Corpus, diferenças que corroboram a hipótese inicial.

The presence of oropharyngeal dysphagia in the pediatric population with genetic diseases it is still poorly studied. The aim of this study was to analyze the oral total transit time and pharyngeal transit time, in an individual with neuronal ceroid lipofucinosis (NCL) with severe oropharyngeal dysphagia. Individual with NCL, 3 years old, 2 years with gastrostomy and no oral feeding, weighting loss, but without pulmonary complications. Oropharyngeal swallowing was studied by videofluoroscopy and it was realized a quantitative analysis using software. Changes were observed throughout the whole biomechanics of swallowing. The quantitative analysis of total oral transit time was found 45.37 seconds (default normality in children is 4 seconds) and for pharyngeal transit time was 4.53 seconds. It was found that beside the changes in the biomechanics of oropharyngeal swallowing in the case studied, an increase in total oral transit time and pharyngeal transit time was also observed, which can significantly compromise the nutritional status and pulmonary these individuals.

Introdução: O índice de massa corporal elevado no compartimento toraco-abdominal promove alterações no sistema respiratório interferindo nos volumes e capacidades e consequentemente na troca gasosa. Objetivo: Analisar comparativamente a mobilidade tóraco-abdominal relacionando ao índice de massa corporal em crianças. Metodologia: Trata-se de um estudo do tipo transversal com abordagem quantitativa e descritiva. A amostra constou de 70 crianças com idade entre 8 e 12 anos de ambos os sexos e com o índice de massa corporal variável. Foi realizada a verificação da altura, peso, expansibilidade destas crianças em seguida classificadas em três grupos em função dos seus índices de massa corporal: eutróficos (57,1%), com sobrepeso (15,7%) e obesos (27,1%). Resultados: Os resultados obtidos apresentaram diferenças entre o grupo dos eutróficos e dos obesos, indicando, nesta perspectiva, que a mobilidade na região axilar e xifoideana são mais elevadas no grupo dos eutróficos, quando comparado ao dos obesos. Conclusão: Portanto conclui-se que o índice de massa corporal está relacionado a alterações na expansibilidade tóraco abdominal de crianças.

The comet assay is a method of DNA damage analysis widely used to quantify oxidative damage, crosslinks of DNA, apoptosis and genotoxicity of chemicals substances as chemical, pharmaceuticals, agrochemicals products, among others. This technique is suitable to detect DNA strand breaks, alkali-labile sites and incomplete excision repair sites and is based on the migration of DNA fragments by microeletroforesis, DNA migrates for the anode forming a “tail”, and the formed image has the appearance of a comet. The slides can be stained with fluorescence or silver, having differences in the microscopy type used for the analysis and the possibility of storage of the slides, moreover, the first one is a stained-method with more difficulties of accomplishment. The image analysis can be performed by a visual way, however, there is a disadvantage as the subjectivity on the results, that can be minimized by an automated method of digital analysis. This process was studied in this report with the aim to perceive the validation of the digital analysis turning it a quantitative method with larger reproductibility, minimizing the variability and imprecision due to the subjective analysis. For this validation we selected 50 comets photographed in a standardized way and printed, afterwards, pictures were submitted to three experienced appraisers, who quantified them manually. Later, the images were processed by free software ImageJ 1.38x, printed and quantified manually by the same appraisers. The intraclass correlation was higher to comet measures after image processing. Following, an algorithm of automated digital analysis from the measures of the comet was developed; the values obtained were compared with those 12 estimated manually after the processing resulting high correlation among the measures. The use of image analysis systems increases ...(Complete abstract click electronic access below)

The present study evaluated the use of semicircular bending test (SCB) as an alternative to conventional bending test to examine the effect of thermal shock. Still, studies the behavior of fracture surfaces generated by monofractal behavior analysis, which allows us to evaluate the contributions of the microstructure and the mechanical context in forming reliefs during the crack propagation. The fractal analysis is made from elevation maps obtained by reconstruction method by extension of the focus stacks of digital images acquired in microscope. The specimens used were samples semicircular pressed TiO2 (rutile) with and without heat shock, prepared for testing mode I loading. Were also produced, specimens in the form of bars for Weibull statistical analysis. From the three-point bending test, we found the variation of fracture toughness between the samples after the heat shock and natural condition. The SCB test was feasible for the analysis of thermal shock resistance. The results showed that the value of the fracture toughness decreases as the heat shock treatment

As abelhas da espécie Apis mellifera são conhecidas por sua organização social, comportamento devotado e aparente complexidade comportamental, sendo também consideradas excelentes sistemas-modelo para estudos de comunicação, aprendizado e formação de memória. Uma vez que o comportamento social dos insetos é resultante de interações complexas em diferentes níveis de organização biológica, torna-se importante estudar os peptídeos envolvidos nesse processo, já que estes são indispensáveis em muitos processos fisiológicos, funcionando como neurotransmissores, hormônios, toxinas, antibióticos, defensinas, neuromoduladores e neurohormônios. Desta forma, o objetivo do presente trabalho foi padronizar uma metodologia analítica visando à determinação do perfil peptídico do cérebro de abelhas da espécie Apis mellifera utilizando como ferramentas a espectrometria de massas e a cromatografia líquida. Foram coletadas operárias de Apis mellifera com 20 dias de idade, cujos cérebros foram dissecados e devidamente processados visando a posterior separação e identificação dos peptídeos. Foram testadas duas estratégias distintas para a separação e identificação dos peptídeos, denominadas on-line e off-line. Ambas baseavam-se na utilização de um sistema de cromatografia líquida sob fase reversa e um espectrômetro de massas do tipo electrospray/Ion Trap-Time of Flight, mas na primeira essas ferramentas estavam acopladas, enquanto na segunda os dois processos foram realizados separadamente. Tais procedimentos permitiram identificar 19 peptídeos pertencentes às principais famílias de neuropeptídeos de cérebros de abelhas já descritos na literatura, entre elas as Alatostatina, Apidaecina, Corazonina e Taquicininas. Os resultados obtidos indicam que a estratégia off-line foi melhor em comparação à estratégia on-line, devido à possibilidade de se trabalhar com cada fração obtida separadamente para as...

Companies, in general, operate due to the work of its subsystems and this is possible thanks to operational planning that tries to promote the best way to integrate them without giving up the mission, vision and values of the company. The main purpose of a business is to serve customers, but to be successful must take into account other factors such as survival, profitability, growth and operational standpoint to use their resources effectively. The use of tools to support the process of analysis of management decision-making is gaining importance in the context of competitiveness in the world market. The objective of this paper is to present a simulation of the process of forecasting demand to obtain optimal results for a steel company, compare the actual results with order entry and assess the magnitude of the error

The paper presents the radiometric parameters determined by the medical physicist during routine radiotherapy planning service in cases of breast cancer . The contours of the breast volume in patients undergoing radiation breast tumors at the Hospital das Clinicas, Faculty of Medicine , UNESP, Botucatu ( HCFMB ) during the year 2012 were analyzed . In order to analyze the influence of physical and radiometric parameters for the determination of the dose distribution of irradiated breast volume , four measurements of isodose curves were prepared in four different heights breast , and compared with the isodose curves plotted computationally . In the routine of planning , the medical physicist must determine the isodose curve that gives the best dose distribution homogeneity in the irradiated volume . The choice of the treatment plan can be done by dedicated computer systems , which require significantly costly investments available services having better financial support . In the Service of Medical Physics , Department of Radiotherapy , HC FMB , we use a two-dimensional software for determination of isodose curves , however , this software is out of date and frequently becomes inoperable due to the lack of maintenance and it is a closed system without feasibility of interference from computer professionals . This fact requires manual preparation of isodose curves , which are subject to uncertainties due to the subjectivity in the clinical interpretation of medical radiation oncologist and medical physicist responsible for planning , plus dispendiar significant calculation time . The choice of the optimal isodose curve depends on the energy of the radiation beam , the geometry and dimensions of the irradiated area . The contours of the breast studied in this work evaluations showed that , for a given energy input , such as the energy of 1.25 MeV of gamma radiation Unit Telecobaltoterapia , the determination of the percentage depth dose ( PDP ) ...
