A geofísica é um método eficaz para investigação de áreas impactadas pelos mais diversos tipos de contaminantes, principalmente em locais de disposição de resíduos sólidos domiciliares e também utilizada na caracterização de contrastes de propriedades físicas em presença de substâncias poluentes. Este trabalho utilizou o método de Polarização Induzida numa área de disposição de resíduos sólidos desativada, localizada no município de Caçapava do Sul - RS. O aterro está assentado sobre rochas metamórficas fraturadas, pertencentes ao Complexo Metamórfico Vacacaí (Neoproterozóico). Foram realizadas 8 linhas de caminhamento elétrico, com espaçamento de 5 m entre eletrodos e 10 níveis de investigação, além de 83 medidas de direção e sentido de fraturas. O resultado geofísico permite caracterizar a camada de resíduos por baixos valores de cargabilidade. Anomalias verticais abaixo da camada de resíduos são interpretadas como zonas de fratura com possível acúmulo de chorume, caracterizadas por baixos valores de cargabilidade.

Mediante esta pesquisa, estudamos os arranjos configurados pelas artérias mesentéricas cranial e caudal em 30 patos domésticos, 20 machos e 10 fêmeas. Foi realizada a injeção de látex 650 corado no sistema arterial e a seguir as peças foram fixadas em solução aquosa de formol a 10% para posteriormente serem dissecadas. A artéria mesentérica cranial nasce como um vaso ímpar da aorta descendente à altura da 6ª e 7ª costelas, em situação imediatamente caudal à artéria celíaca. Junto à junção íleo-ceco-cólica, subdivide-se basicamente em 3 ramos: o primeiro emite um vaso destinado ao colonreto, anastomosando-se com a artéria mesentérica caudal. O segundo ramo se comporta como tronco para as artérias jejunais, sendo que o número delas varia de 8 a 20. Finalmente, o terceiro ramo destina-se às porções principal e final do ceco direito e também ao íleo, vascularizando-os. No atinente ao comportamento da artéria mesentérica caudal, observamos que ela nasce como um vaso ímpar, a partir da aorta descendente, à altura das porções caudais dos rins. A artéria mesentérica caudal, na totalidade das peças examinadas, divide-se em 2 ramos: um cranial, que, por sua vez, emite 2 vasos menores para o mesorreto e um ramo caudal, que vasculariza a porção terminal do reto, bolsa cloacal e a cloaca.

The disposition of the abdominal aorta branching in Mesocricetus auratus is described, establishing variation groups with relation to the celiac, cranial mesenteric, renal, genital and caudal mesenteric arteries. Sixty animals (30 males and 30 females) of different ages and weights, were anesthetized with chloroform, injected with contrasting substance in the abdominal aorta (50 animals with Neoprene latex and 10 with a radioopaque mass), after which they were dissected with the help of a stereoscopic microscope. The animals with radioopaque masses were radiographed in comparison with the other animals. The results are expressed in relative percentage figures and compared with other mammalian arterial dispositions.

Raven's Progressive Matrices were completed by 536 school children. Wechsler's Intelligence Scale for Children was applied to children who performed badly on Raven's Test (percentile 5 or less). Father's occupation and education, items of property and sums of spending money were assessed in all families. Clinical history and physical examination were recorded for deficient children. Mental deficiency was present in 94 children (17.5%); it was more frequent in those from lower socioeconomic classes (90 deficient children in a total of 427); it was more frequent in the peripheral school (69 deficient children) than in the midtown school (relatively less poor children); no significant difference was found in sex distribution among social classes. 67 children had an intelligence quotient between 50 and 69. Undernourishment was severe marked (18 children), moderate (48 children) or absent (26 children). Most children (67) were insufficiently stimulated by their parents.

Ultrastructural evaluation of the collagen of the mongrel dog medial collateral ligament associated to the oblique ligament after strain. The present work aimed to observe the disposition of the collagen fibres of the medial collateral ligament of the elbow joint of the dog, when associated to the oblique ligament. Thus, 18 articulations were used, divided in three groups. A group had the medial collateral ligament collected and not stretched, other group had the collateral medial ligament stretched separately and the other group had both ligaments (medial collateral and oblique) stretched associately. The medial collateral ligament examined by scanning electron microscopy presented a wavy and reticular pattern of the collagen fibres when not submitted to strain, which was not totally destroyed when it was associated to the oblique ligament. When stretched separately, the medial collateral ligament after strain totally loses the reticular pattern, demonstrating the waste of the fibres to resist to the tension.

This article describes the application of an Artificial Intelligence Planner in a robotized assembly cell that can be integrated to a Flexible Manufacturing System. The objective is to allow different products to be automatically assembled in a single production line with no pre-established assembly plans. The planner function is to generate action plans to the robot, in real time, from two input information: the initial state (disposition of parts of the product in line) and the final state (configuration of the assembled product).

Landfill is an engineering work that aims at to accommodate residues in the smallest possible space in the soil, with minimum damages to the environment and the public health. One in the constructive forms of a controlled landfill is the excavation of ditches with appropriate dimensions, for disposition of solid residues without compactation or impermeabilization. Liquid effluents generated for similar volumes of residues, disposed in ditches with ages different from closing, it should result in physical and chemical alterations you correlated at the time of residence materials. With base in this hypothesis, measures of electric resistivity were accomplished through the of Eletrical Resistivity geophysical method, on residues ditches closed annually between 12/2001 and 12/2007, localized in control landfill of the Cordeirópolis city (SP). The leachate is a liquid effluent generated by the decomposition of organic matter and characterized by high content in total dissolved solids, whose interaction with geological environment results in alterations in terms of electrical resistivity susceptible to detection for the geophysical instrumental. The results suggest a resistivity reduction for leachate percolation produced for ditches recently and increase progressive of the resistivity for older ditches. The statistical comparative analysis with reference values for the area suggests ages of the finish production and percolation leachate for soil and rock below the ditches.
