Gouveia, Viviane de Araújo;Victor, Edgar Guimar?es;Lima, Sandro Gonalves de;
Revista Latino-Americana de Enfermagem , 2011, DOI: 10.1590/S0104-11692011000500004
Abstract: this case series aimed to evaluate the behavior adopted by patients during the pre-hospital phase of acute myocardial infarction (ami). a total of 115 ami sufferers with st-segment elevation were evaluated. the chi-square and fisher's exact tests were applied. the individuals that did not associate the symptoms with cardiovascular disease most often attributed them to the following sources: gastrointestinal (38%), musculoskeletal (29.7%), food and/or medication poisoning (8.5%) and arising from the respiratory apparatus (6.3%). the proportion of major outcomes and of patients that arrived in the emergency department after 12 hours was higher among women, individuals with monthly income of up to one minimum wage, those who used analgesics and did not associate the symptoms with cardiovascular disease. it was found that individuals in unfavorable socioeconomic conditions, who interpreted the symptoms incorrectly, arrived later at the emergency department and had worse intra-hospital outcomes.

Abstract: The adoption of performance indicators promotes knowledge of quantitative and qualitative material wastes in businesses and, when inserted in a collaborative process, provides a comparative evaluation of results between companies and, thereafter, an identification of best practices (bench-marking). The purpose of this paper is to present the best practices identified by performance indicators, related to the measurement of wastes and associated to construction companies participation in the benchmarking research process “Implementation of a system of performance indicators of cement-based construction technologies of the Community of Construction of Recife city in Brazil-PROGRIDE”, coordinated by the Brazilian Association of Portland Cement-ABCP. Therefore, it was sought to characterize best practices that led to the benchmarking of performance indicators related to the wastes of concrete, industrialized mortar for masonry settling and blocks/ bricks. As a contribution, a set of factors that characterize the best practices for each technology and conducted to benchmarking were identified.
Rotational Oscillation Effect on Flow Characteristics of a Circular Cylinder at Low Reynolds Number  [PDF]
Alice Rosa da Silva, Aristeu da Silveira-Neto, Ant?nio Marcos Gonalves de Lima
World Journal of Mechanics (WJM) , 2015, DOI: 10.4236/wjm.2015.510019
Abstract: Two dimensional numerical simulations of flow around a rotationally oscillating circular cylinder were performed at Re = 1000. A wide range of forcing frequencies, fr, and three values of oscillation amplitudes, A, are considered. Different vortex shedding modes are observed for a fixed A at several values of fr, as well as for a fixed fr at different values of A. The 2C mode of vortex shedding was obtained in the present study. It is important to point out that this mode has not been observed by other investigators for rotationally oscillating case. Also, it is verified that this mechanism has great influence on the drag coefficient for high frequency values. Furthermore, the lift and pressure coefficients and the power spectra density are also analyzed.

Revista Brasileira de Economia , 2011, DOI: 10.1590/S0034-71402011000400001
Abstract: this paper studies the relationship between political regimes duration and growth using data for 1950-2005. using econometric duration models to evaluate the so-called modernization hypothesis we find evidence supporting the idea that a democracy enjoys longer duration in richest and more educated countries. however, the duration of dictatorships does not seem to be affected by economic growth or the rise of educational attainment.
