T he people’s daily lives are surrounded by computing devices, with increasing resources (sensors) and, with increasing processing. How these devices communicate is still not natural and This retards the growth of Ubiquitous Computing. This paper presents a way in which these devices can communicate using Jini technology and concepts of Service Oriented Architecture, applying these concepts in a test case of Ubiquitous Computing. To conduct the test case was constructed a fictitious system for management of a soccer championship, where users can interact with each other and with the system in a simplified way, have access to data in real time of the championship during the event. This communication is performed by services built using Jini technology, which were based on key SOA concepts, such as modularity and reusability

In this paper we consider the problem of differential inclusion in time scales whose vector field is a multifunction, that is, a function that maps points to sets. It is provided conditions of existence without requiring compactness of the vector field; it is required that the vector field is closed, convex, and lower semicontinuous. In previous work in literature, it is required that the field is either scalar or compact, convex, and has closed graph.

Há um crescente interesse nas técnicas reprodutivas, por agilizar a procriação de populações animais de interesse econômico, a preservação de espécies em extinção ou a utilização como modelo experimental em outras espécies. A reprodução de felinos em cativeiro é dificultada devido ao ambiente estranho, o que os leva a apresentarem alterações na própria fisiologia. Torna-se importante o estudo de fenômenos reprodutivos destes animais com a finalidade de melhor compreensão e, posteriormente, adaptação adequada das biotécnicas reprodutivas. A atuação da apoptose na fisiologia ovariana ainda não é bem compreendida, havendo a necessidade da comunidade científica elucidá-la melhor. O objetivo deste trabalho foi testar a hipótese de que os índices de apoptose no tecido ovariano são diferentes em gatas jovens, adultas e idosas. Foram utilizadas 18 gatas distribuídas em 3 grupos contendo 6 animais cada, de acordo com a idade (jovens, adultos e idosos). As amostras do tecido ovariano destinadas a avaliação de apoptose, foram submetidas ao método terminal deoxynucleotidyltransferase-biotin nick end-labelling (TUNEL). Os dados referentes aos diferentes grupos foram submetidos à análise de variância e as médias foram comparadas pelo Teste de Tukey. Não houve diferença significativa quanto ao número de folículos e número de células positivas das gatas jovens, adultas e idosas, sendo P < 0,05. O resultado do trabalho sugere que o fenômeno da apoptose em tecido ovariano em gatas não possui relação com a faixa etária, ou seja, a apoptose ocorre de forma contínua nos folículos não-dominantes envolvidos em cada ciclo estral apresentado

A study was conducted to determine the optimal time for collecting the breath examination urea breath marked with the stable isotope 13C. We selected patients before undergoing the examination of endoscopy at the Endoscopy Section of the University Hospital of Botucatu - SP. A screening was performed to determine which patients wanted and could participate. Before performing endoscopy basal sample was collected from the patient and then the labeled urea ingested. The blows were collected in double every 2.5 minutes until an interval of 30.0 minutes after were collected every 5.0 minutes until the time of 45.0 minutes . The samples were analyzed in a mass spectrometer for isotope ratio, located in the center of Stable Isotopes, Institute of Biosciences, UNESP - Botucatu campus. The data were studied and arranged in the form of graphics to better interpretation of results. Based on the obtained results it was determined that a standby time of 15.0 minutes to collect the wind is sufficient for accurate diagnosis and effective

The correct distinguishment of microorganisms involved in the periodontal disease pathogen, it is important in the understanding of its progression and adequate treatment planning. Considering this fact, some molecular methods of identification and quantification were developed and are extremely sensitive and precise in the characterization of different bacteria species. The present study aimed to realize a literature review, including studies that realized a comparative analysis between bacterial culture and real time PCR methods in the identification of pathogens. The bacterial culture method can possibly identify new microorganisms and realize antibiotics sensitivity tests. The real time PCR is a microbiologic test that identifies and quantifies bacterial species, through gene amplification of predetermined DNA fragments, with high sensitivity and specificity, and need a shorter operation time of the operator when compared to the bacterial culture method. In this way, to determine a specific diagnostic test, should be considered not only its precision in the identification of microorganisms, but the cost-benefit relationship as well.

The objective of this study was to estimate the reliability of the alcohol use disorders identification test (AUDIT) applied to adolescents. Evaluations were performed with 141 students of ages ranging from 14 to 17 years (14.93±0.62). The internal consistency of the instrument was estimated by Cronbach’s alpha coefficient and its reproducibility by weighted Kappa statistics by score and by a reliability interval of 95%. The AUDIT presented excellent internal consistency (α=0.80, rinter-item=0.29). Most questions present reproducibility ranked as “good”. It is concluded that the AUDIT is a reliable instrument to survey information about alcohol use in adolescents.
