Microbialitos da formação Codó (Aptiano Superior) às margens do rio Tocantins em São Miguel do Tocantins (TO)

The southwestern region of the São Luís-Grajaú Basin has a rare outcrop of the Codó Formation (upper Aptian) with seven outstanding microbialite bioherms along the left margin of the Tocantins river, near Imperatriz (MA). Resting on sandstones of the Grajaú Formation, the Codó Formation presents: 1) a 20 cm thick basal calcilutite with gypsite pseudomorphs and some fossil tree stems; 2) metric dark shales with carbonate nodules and thin intercalated carbonate layers, enclosing some microbial laminites; 3) a 2 cm thick upper breccia composed of microbialite fragments and other carbonate clasts, with halite hoppers on the top; 4) the carbonate bioherms, which partially overlie the extensive shales and interrupt them laterally, as well as the breccia. The bioherms in the northern part of the outcrop are thicker (<2 m) and have interbedded dark shales, whereas the southern are thinner and continuous in the vertical direction. In general, they are composed of irregular gently to strongly wavy microbial laminites, sometimes with pseudocolumnar to conical lamination. All microbialites with highest synoptic relief (<20 cm) look like columnar stromatolites on weathered lateral expositions. In plan view, the horizontal sections of these microbialites are circular to slightly elliptic, sometimes forming very small channels (N60W) filled with fine breccia. The highest bed of the northern bioherm has mixed microbial laminites and columnar stromatolites, where intercolumnar spaces were filled with microbialite clasts, fish bones, plant fragments and very small probable crustacean coprolites. Several fractures and deformation in this upper bed indicate an initial brecciation process probably caused by subaerial exposure. In microscopic scale, the lamination is smooth, diffuse, defined by subtle granulation differences of very fine granular calcite crystals within micrite, but oxide levels, dissolution surfaces or thin precipitated calcite veneers...

Cine física: estudo de vídeos e filmes e possibilidades para o ensino de física na educação básica

In this work we present a didactic proposal of the use of movies and videos for the Physics teaching directed to the Basic Education and we bring a discussion about how the materials addresses this topic. For this, we selected three cinematographic works, one chapter of the TV show and videos found in the web and we analyse the physics concepts found particularly about the issue electromagnetism. We developed the activity denominated Cine - Física in a public school from Rio Claro - SP, through presentations of these movies, shows and videos. Those works were exhibited in full and then we discussed the concepts involved in these movies. With the perform of this didactic proposal we verified that is possible insert the use of movies and videos in the classroom activities, and go beyond the entertainment or using those materials as supplements of classes. Dialoguing with students was possible to realize that they visualize the effects and physical concepts in a different way than other that used to be shown in the blackboard through formulas, providing positive effects to the learning of Physics

Características fenotípicas do nanismo em pôneis neonatos: relato de casos

Three newborn Mini-Horses and one Brazilian Pony horses were presented to the Veterinary Hospital with phenotypic appearance of dwarfism. They had relatively larger head conformation, occlusive dental defect and musculoskeletal changes such as abnormal short limbs and deformation on the third metatarsal bone. The radiographic examination showed abnormal growth plates on femoral condyle and proximal thirds metatarsal bones. Due to the high possibility of future complications and quality of life loss, the animals were euthanized. We emphasize the importance of recognition of phenotypic changes related to dwarfism in horses, enabling the phenotypic diagnosis can direct crossings for nontransmission of this abnormality as genetic inheritance.

Perfil da renda e do volume dos resíduos sólidos urbanos da associação de catadores de São Manuel - SP

The implementation of residue selective collection has brought to the city of Sao Manuel an incalculable benefit. It brought a better life for a group of adults and children that lives in a humanitarian condition of extreme poverty. These people live in an open-air dump, disputing the remains found in fifteen tons of garbage that are deposited at the site almost every day.The objective of this paper is to present thecollectors annual income profile and the volume of solid waste collected.To present these factors, the total and fractionated amount according to their material items, collected since the creation of the Association in February 2003 until December 2008, were considered., In addition,the social gains were enumerated. These factors were developed from a theoretical base for municipal solid waste involving environmental, social, and financial concepts. Based on these results it was found that the ACAPEL income value was above the average of other income indicators of the population analyzed, besides the social value enhance that the creation of the Association brought to the people who work there.

Atividade de comunicação e de trabalho

Este artigo discute o binômio comunicação e trabalho a partir da perspectiva da ergologia, ou seja, da atividade humana. Faz uma breve retrospectiva das teorias de comunicação, analisando como as correntes teóricas hegemônicas vêem de maneira limitada os processos de comunicação. E discute sobre os conceitos de comunicação e de trabalho, propondo uma abordagem de pesquisa que permita melhor compreender esse binômio.

CARING FOR TUBERCULOSIS PATIENTS IN THE FAMILY HEALTH STRATEGY: THE NURSES' PERCEPTIONS

The objective of this study was to analyze the nurses' perceptions regarding tuberculosis control, according to the theoretical axis of comprehensive healthcare and the concepts of attachment and teamwork. This qualitative study involved 13 nurses from the Family Health Strategy of a priority city in the metropolitan region of Joao Pessoa, Paraiba, Brazil. Data were collected in focal groups and subjected to thematic content analysis. Factors that strengthen tuberculosis control were: supervised treatment, free medication and the provision of supplies. Weakening factors were: worker's turnover, the lack of encouragement for patients and incipient educational actions. The factors that, according to the nurses, weaken tuberculosis patient care should be reviewed by administrators, workers, users and educators with a view to redefining healthcare activities that strengthen attachment, comprehensive healthcare and teamwork.

PHOTOELASTIC ANALISYS IN THE LOWER REGION OF VERTEBRAL BODY L4

Objective: To analyze the shear forces on the vertebral body L4 when submitted to a compression force by means of transmission photoelasticity. Methods: Twelve photoelastic models were divided into three groups, with four models per group, according to the positioning of the sagittal section vertebrae L4-L5 (sections A, B and C). The simulation was performed using a 15N compression force, and the fringe orders were evaluated in the vertebral body L4 by the Tardy compensation method. Results: Photoelastic analysis showed, in general, a homogeneous distribution in the vertebral bodies. The shear forces were higher in section C than B, and higher in B than A. Conclusion: The posterior area of L4, mainly in section C, showed higher shear concentrations, corresponding to a more susceptible area for bone fracture and spondylolisthesis.
