Claus Dieter Stob?us, Simone Stochero Kummer, Carolina Schaan Pessano, Jordana Wruck Timm, Juan José Mouri?o Mosquera
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.912136
Abstract: The article attempts to examine aspects of aging, in a positive sense, understanding Education as an aid to preventative measures in the health-care of the elderly, leading to aspects of health and quality of life, emotional health and well-being of the elderly within the framework of Positive Psychology, and its application to educational activities for the elderly. Health is currently a highly popular topic of discourse in all media platforms. Doctors and professionals in the field, in addition to other interested public bodies, comment daily on the issues involved in this topic and, principally, there is now a concern with the planning of preventative measures, as a factor that can guarantee a better quality of life and greater longevity. In addition to the discussions between the authors within the research group Teaching and Learning in Biomedical Gerontology of PUCRS, we used elements developed in our classes in Biomedical Gerontology with our students1.
Long-Term Human Induced Impacts on Marajó Island Landscapes, Amazon Estuary

Abstract: Archaeology is a discipline that can offer a long term perspective on the impacts human societies have had on the environment. Landscape studies are critical for understanding these impacts, because they embrace a dialectical view regarding the relationship between humans and their immediate surroundings. Such studies are well suited to the Amazon basin, a region that has driven much media attention due to astonishing rates of deforestation in certain areas, with likely consequences on the planet’s climate, posing challenges to the survival of the human species for the coming decades. In fact, although much has been said about the impacts of contemporary societies on tropical forest environments, ancient landscape management practices have not yet been considered part of the equation. Thus far, we know that Amerindian societies have been actively transforming their surroundings for millennia. On the eve of European contact, large, complex societies were bringing about long-lasting transformations of landscapes throughout the basin. Conquest and colonization resulted in epidemics, enslavement, and changes to the indigenous economies that managed to survive the genocide. Afterwards, as colonizers would exploit traditional resources leading, in many instances, to their exhaustion, a huge quantity of information on sustainable ways of dealing with certain environments became lost. Traditional knowledge, however, still survives among certain indigenous, peasant (caboclo), and African-Brazilian populations. Documentation of surviving management practices together with the study of the archaeological record could provide valuable information for policy makers. This article examines historical transformations that took place on Marajó Island during the last two millennia and advocates the importance of archaeological research for understanding the historical ecology of landscape change. It is argued that ancient economic strategies, some still being practiced today, could be re-created in the present, since these may constitute opportunities for sustainable sources of income to local communities.
O papel da proteína quinase C no desenvolvimento das complica??es vasculares do diabetes mellitus
Schaan, Beatriz D.;
Arquivos Brasileiros de Endocrinologia & Metabologia , 2003, DOI: 10.1590/S0004-27302003000600006
Abstract: mortality of diabetic patients is higher than that of the population at large, and results mainly from cardiovascular diseases. the putative mechanisms for the progressive atherosclerosis these patients present are direct toxic effects of glucose upon vasculature, insulin resistance, and the association of diabetes (dm) with other cardiovascular risk factors. the main determinant of the tissue damage caused by dm is hyperglycemia, which results in high intra-cellular glucose, high diacylglycerol (dag) and activation of protein kinase c (pkc). this review intends to compile the effects of hyperglycemia upon the dag-pkc pathway, vascular dysfunction related to it, and new perspectives regarding treatment of vascular chronic complications of dm based in the inhibition of this pathway.
Uma janela para a história pré-colonial da Amaz?nia: olhando além - e apesar - das fases e tradi??es
Schaan, Denise Pahl;

Abstract: in this article, it is in debate the assumed correlation between pottery industry (phase) and social group. it is argued that this assumption is not adequate to understand either variability or change in material culture. three case studies are presented in order to demonstrate that technological and iconographic similarities between artifact assemblages might correspond to different sociopolitical organizations and subsistence patterns; the identification of stylistic variability inside of a single phase might signalize political limits, as well as sociocultural identities; and typological variation (especially regarding decoration), used to define distinct phases, might mask cultural continuity and sociopolitical change within a single territory.

Abstract: A mortalidade dos pacientes com diabetes (DM) é maior do que a da popula o em geral e decorre especialmente das doen as cardiovasculares. Os prováveis mecanismos da aterosclerose acelerada nestes pacientes s o os efeitos tóxicos diretos da glicose sobre a vasculatura, a resistência à insulina e a associa o do DM a outros fatores de risco para doen a cardiovascular. O principal determinante do dano tecidual causado pelo DM é a hiperglicemia, resultando em aumento de glicose intra-celular, aumento de diacilglicerol (DAG) e ativa o da proteína quinase C (PKC). Esta revis o tem por objetivo compilar os efeitos da hiperglicemia sobre a via DAG-PKC, a disfun o vascular relacionada a ela, e, finalmente, as novas perspectivas de tratamento das complica es cr nicas vasculares do DM baseadas na inibi o desta via.

Abstract: objective: the present study was aimed at evaluating the occupational exposure of nursing staff in charge of inpatients undergoing 131i therapy during 11 years. materials and methods: the exposure situations were classified according to a questionnaire answered by three nursing attendants, correlating the procedures with activities, distances and amount of time in the iodotherapy room. records of received doses by two types of dosimeters were evaluated over two subsequent periods. in both periods the nursing attendants received instructions about radiological protection. results: in usual situations, their amount of time in the iodotherapy room was in compliance with the standard time established by the service. in unusual situations, where the patient needed assistance for mobility, the exposure period was above the standard. however, this exposure occurs casually (only one or two times a year). during the period between 1993 and 1999 (dosimetric films) there were ten dose records, all of them at record level. from 2000 to 2003 (thermoluminescent dosimeters) ten dose records were also obtained, with only one of them at the investigation level. during this study period, the mean 131i activity was doubled. conclusion: despite the increased levels of activity there was no significant increase in dose to nursing attendants.
The stability of stratified, rotating systems and the generation of vorticity in the Sun
Steven A. Balbus,Emmanuel Schaan
Physics , 2012, DOI: 10.1111/j.1365-2966.2012.21729.x
Abstract: We examine the linear behavior of three-dimensional Lagrangian displacements in a stratified, shearing background. The isentropic and iso-rotation surfaces of the equilibrium flow are assumed to be axisymmetric, but otherwise fully two-dimensional. Three-dimensional magnetic fields are included in the perturbation equations; however the equilibrium is assumed to be well-described by purely hydrodynamic forces. The model, in principle very general, is used to study the behavior of fluid displacements in an environment resembling the solar convection zone. Some very suggestive results emerge. All but high-latitude displacements align themselves with the observed surfaces of constant angular velocity. The tendency for the angular velocity to remain constant with depth in the bulk of the convective zone, together with other critical features of the rotation profile, emerge from little more than a visual inspection of the governing equation. In the absence of a background axial angular velocity gradient, displacements exhibit no poleward bias, suggesting that solar convection "plays-off" of prexisting shear rather than creates it. We argue that baroclinic vorticity of precisely the right order is generated at the radiative/convective zone boundary due to centrifugal distortion of equipotential surfaces that is not precisely followed by isothermal surfaces. If so, many features of the Sun's internal rotation become more clear, including: i) the general appearance of the tachocline; ii) the extension of differential rotation well into the radiative zone; iii) the abrupt change of morphology of convective zone isorotation surfaces; and iv) the inability of current numerical simulations to reproduce the solar rotation profile without imposed entropy boundary conditions.

Biotemas , 2005,
Abstract: With the aim of identifying the composition of the ichthyofauna from Quarai-Chico creek (a tributary of the middle Uruguai river located in the municipality of Barra do Quarai), seasonal samplings were taken over the period of one year, from April 1997 to March 1998. Captures were made by means of electrical fishing techniques. A total of 3,564 specimens were captured, distributed in 37 species, 27 genders and 14 families. The Characidae family demonstrated the highest representivity, with 12 species captured, while the Anostomidae, Gymnotidae, Heptapteridae, Pimelodidae, Poecillidae, Synbranchidae and Sternopygidae families each produced evidence of only a single species. In general teams, the results obtained demonstrated a higher ichthyic diversity than the other creeks in the region of the Western frontier of Rio Grande do Sul.
