2. Comparison of Arterial Repair through the Suture, Suture with Fibrin or Cyanoacrylate Adhesive in Ex-Vivo Porcine Aortic Segment
Abstract Introduction: Tissue adhesives can be used as adjacent to sutures to drop or avoid bleeding in cardiovascular operations. Objective: To verify the efficiency of fibrin and cyanoacrylate adhesive to seal arterial sutures and if the adhesives penetrate through suture line to the inner of arteries. Methods: 20 abdominal aorta segments of pigs were d

3. AvaliaÃÃo dos efeitos renais da fraÃÃo L-aminoÃcido Oxidase isolada do veneno da serpente Bothrops marajoensis. / Assessment of renal effects of L-amino acid oxidase fraction isolated from snake Bothrops marajoensis venom.
There are about 3.000 species of snakes worldwide, but only 10 to 14% are venomous. Among South American countries, Brazil is the one with the largest number of accidents, with approximately 20.000 snakebites each year. According to the Department of Health of Brazil, the genus Bothrops are the main involved in snakebites in the country. Acute renal failure

4. Estudo experimental de escoamentos líquido-gás intermitentes em tubulações inclinadas / Experimental analysis of slug flow in inclined lines
This work analyses experimentally the flow properties of a gas-liquid mixture flowing in the slug regime in inclined lines. The experimental data are collected through a pair of impedance probes placed at 77D and 257D downstream of the air-water mixer in a 26mm ID pipe. During the tests air and water superficial velocities spanned, respectively, from 0,1 m/s

5. Brazilian Portugueses nasal diphthongation: an acoustic and aerodynamic analysis of speech / A ditongação nasal no português brasileiro: uma análise acústico-aerodinâmica da fala
There are several studies that characterize the nasal vowels. However, there are few studies about the nasal diphthongation. This phenomenon emerges from the articulatory gestures constellation. This can be noted by analyzing of the acousticaerodynamics parameters. The aim of this work is study the gesture configuration between the thong movement and the vel

6. Análise das dificuldades na disciplina de bioquímica diagnosticadas por um plantão de dúvidas on line / Students difficulties in biochemistry discipline analyzed through an on line academic drop-in center
The biochemistry discipline integrates the curriculum of all graduation courses on the Biological Area and is a basis for other disciplines. The students difficulties in this discipline are already widely recognized. To investigate these difficulties, we created a drop-in on line service that had three purposes: (i) to give support to students learning by an

7. Assembly and evaluation of a cooling tower for use in teaching undergraduate activities / Montagem e avaliação de uma torre de resfriamento para uso em atividades de ensino de graduação
This work describes proposal for complementing Process Systems Engineering (PSE) undergraduate learning. Traditional teaching of PSE is normally restricted to modeling and computer simulations, with very little contact with actual processes. We felt that applying theoretical concepts to practical problems would be very welcome by the students and improve the

8. Efeito da ação tópica do colírio de fenilefrina a 10% no posicionamento palpebral de indivíduos normais e portadores de blefaroptose adquirida involucional / Effect of 10% phenylephrine eye drops action in the eyelid position in healthy subjects and in patients with acquired involutional blepharoptosis
INTRODUCTION: There are few studies in the literature on the effect of drugs on the vertical positioning of the eyelids. This issue is important in the analysis of the eyelid dynamics mainly in disorders such as blepharoptosis. The aim of this study is to determine the action of a single drop of 10% phenylephrine on the upper and lower eyelids of healthy sub

9. Identificação e monitoramento de regimes de escoamento em leito de jorro
Spouted bed has been studied intensively because of its potential of application in several processes. Identification and characterization of flow regimes in spouted bed based on visual observation have been reported in literature. However, the characterization of flow regimes based on visual observation is not either usual or possible in industrial equipmen

10. Distribution system FACTS (flexible AC transmission systems) application - performance simulation. / Aplicação do dispositivo FACTS (Flexible AC Transmission Systems) em sistema de distribuição -simulação de desempenho.
The new FACTS technologies applied to the transmission system, based on power electronics, can also be useful to the distribution. For that, it is necessary to drive a procedure to consolidate the use and the performance for their application without risks. In this work two aspects will be approached. The first refers to the application of a FACTS device act

11. Sistemas integrados de gestão empresarial: um estudo sobre percepção das empresas adotantes.
ERP Systems (enterprise resource planning) have been widely spread over the industrial sector since the nineties. Their implementation, replacing the old legacy systems, promoted a level of integration of the processes never reached by the adopter companies before. However, some features - especially their complexity, the fact it is a package which is both c

12. Adsorção de tensoativos em resina trocadora de cations
A tensiometric detector based on surface tension measurement by the drop-weight method (TSDMG) was built and fitted in a standard liquid chromatograph (together with an UV photometric detector) to monitor surfactants in a liquid flow by dynamic surface tension (gd) measurements. The gd values obtained for aqueous solutions of polyethylene glycol mono [p-1,1,
