1. A new experimental model of intrinsic denervation in ileum from wistar rats through intramural microinjections of benzalkonium chloride
RESUMO: Existe vasta literatura sobre a desnervação intrínseca de segmentos do tubo digestório através da aplicação de CB na serosa da víscera. Entretanto, essa técnica tem a desvantagem de causar peritonite, formação de bridas e alta mortalidade, não sendo factível para eventuais utilizações em humanos. O objetivo do presente estudo foi avali

2. Using UAV for automatic lithological classification of open pit mining front
Abstract Mine planning is dependent on the natural lithologic features and on the definition of their limits. The geological model is constantly updated during the life of the mine, based on all the information collected so far, plus the knowledge developed from the exploration stage up to the mine closure. As the mine progresses, the amount of available dat

3. 2D magnetometric modeling of a basic-intermediate intrusion geometry: geophysical and geological approaches applied to the Limeira intrusion, Paraná Magmatic Province (SP, Brazil)
ABSTRACT: The Limeira Intrusion is an occurrence related to the Mesozoic continental flood basalts of Paraná Magmatic Province, cropping out at the eastern São Paulo state. It is made up of basic-intermediate rocks with a great diversity of structures, textures and modal compositions, related to specific evolutionary process in a magma chamber. Previous ge

4. Status and Trends of Smallsats and Their Launch Vehicles — An Up-to-date Review
ABSTRACT This paper presents an analysis of the scenario of small satellites and its correspondent launch vehicles. The miniaturization of electronics, together with reliability and performance increase as well as reduction of cost, have allowed the use of commercials-off-the-shelf in the space industry, fostering the Smallsat use. An analysis of the launche

5. Carbon Fiber Reinforced Polymer and Epoxy Adhesive Tensile Test Failure Analysis Using Scanning Electron Microscopy
Morphological characteristics analysis before and after tensile tests were studied using scanning electron microscopy (SEM) technique to follow the failure evolution on carbon fiber reinforced polymer (CFRP) and epoxy resins. Micrograph analysis of CFRP plate before tensile test shows some intrinsic manufacturing defects, which can influence the mechanical p

6. Oxytocin and arginine vasopressin receptor evolution: implications for adaptive novelties in placental mammals
Abstract Oxytocin receptor (OXTR) and arginine vasopressin receptors (AVPR1a, AVPR1b, and AVPR2) are paralogous genes that emerged through duplication events; along the evolutionary timeline, owing to speciation, numerous orthologues emerged as well. In order to elucidate the evolutionary forces that shaped these four genes in placental mammals and to reveal

7. Effect of the mechanical properties and mode loading on the mechanical behaviour of weldment: a numerical analysis
Welding is used to realize permanent assembly in mechanical structures to assure the continuity of the parts to be assembled contrary to the other assembly techniques which have physical or chemical discontinuities. Generally, crack evolution depends on several intrinsic and extrinsic parameters of material. The aim of this work is to analyse the severity of

8. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

9. ESTUDO GEOMETALÚRGICO DE GRANULADOS E PELOTA DE MINÉRIO DE MANGANÊS / ESTUDO GEOMETALÚRGICO DE GRANULADOS E PELOTA DE MINÉRIO DE MANGANÊS
Aiming to characterize intrinsic properties of granular products and pellets of manganese ore, this study proposes an experimental methodology to allow the evaluation and comparison of the quality of five lumpy manganese ores and a manganese pellet. The work presents chemistry, mineralogy, density, specific surface and porosity, in addition to the metallurgi

10. Probabilidade de progressão por série no Brasil: evolução, seletividade e aplicação de modelos de idade-período-coorte
The provision of the universal access to schooling and the assurance of students permanence in school has been the object of public policies in almost all nations. Education is conceived not only as a form of individuals emancipation, but also as an important factor to promote the economic and social development. Since the 90s, Brazil has seen the implementa
