1. Dynamic Changes in Perioperative Cellular Inflammation and Acute Kidney Injury after Coronary Artery Bypass Grafting
Abstract Introduction: This study investigated the role of the neutrophil-lymphocyte ratio (NLR), the perioperative changes in NLR (delta-NLR), the platelet-lymphocyte ratio (PLR), and the platelet count in predicting acute kidney injury (AKI) following coronary artery bypass grafting (CABG) during hospital stay. Methods: The records of 396 patients with p

2. As políticas científicas na era do conhecimento: uma análise de conjuntura sobre o ecossistema científico global
Resumo A proposta deste trabalho é realizar uma análise de conjuntura sobre a ciência brasileira, a partir de um olhar sobre a geopolítica do conhecimento, no qual a informação se consolida como uma importante ferramenta de disputa de poder. Neste sentido, a proposta deste ensaio é desvendar os atores e os discursos mercadológicos e ideológicos tant

3. ENERGY EFFICIENCY OF A CENTER PIVOT IRRIGATION SYSTEM
ABSTRACT This study aimed to evaluate the energy efficiency of a center pivot irrigation system operating in a terrain of variable topography. Values of Pumping Energy Efficiency (PEE), Supply Energy Efficiency (SEE), Global Energy Efficiency (GEE) and Specific Energy (Es in kWh m-3) computed at 18 different angular positions of the lateral line were used as

4. An Innovative Structural Fatigue Monitoring Solution for General Aviation Aircraft
ABSTRACT: This article proposes a novel and effective solution for estimating fatigue life of General Aviation (GA) airframes using flight data produced by digital avionics systems, which are being installed or retrofitted into a growing number of GA aircraft. In the proposed implementation, a flight dynamics model is adopted to process the recorded flight d

5. Divergences Between New Patterns of Global Trade and Brazil/Mercosur
Although integration has been a part of South American discourse for decades, the level at which it is actually promoted remains far from that which is observed in dynamic production and trading centers. Given transformations in global trade, the phenomenon of global value chains is, in fact, very regionalized. We ask whether the trading pattern of Mercosur

6. Regions and the Globe: A Spatial-Temporal Framework for Foreign Policy Analysis
Does the regional environment shape a state's international socialization and, thus, its perception on external affairs? If this is the case, how does such a process happen and what are the consequences for a state's global foreign policy? We tackle both questions by elaborating an analytical framework that accounts for spatial-temporal interactions in forei

7. The Long-Range Memory and the Fractal Dimension: a Case Study for Alcântara
ABSTRACT: This study aimed to analyze the time series behavior of the Southern Oscillation Index through techniques using Fast Fourier Transform, computing the autocorrelation function, and the calculation of the Hurst coefficient. The methodology of Hurst Exponent calculation uses different lags, which are computed in the time series of Southern Oscillation

8. A high-level dynamic analysis approach for studying global process plant availability and production time in the early stages of mining projects
Abstract In the early stage of front-end studies of a Mining Project, the global availability (i.e. number of hours a plant is available for production) and production (number of hours a plant is actually operated with material) time of the process plant are normally assumed based on the experience of the study team. Understanding and defining the availabili

9. Agriculture and food security challenge of climate change: a dynamic analysis for policy selection
ABSTRACT This study presents an empirical examination of climate change related to vulnerability impacts on food security and remedial adaptation options as a suitable strategy by prioritizing needs over a 50-year period. An Empirical Dynamic Commutable General Equilibrium Model for Climate and the Economy (EDCGECE) is applied using future strategies for Mal

10. A new FEM procedure for transverse and longitudinal vibration analysis of thin rectangular plates subjected to a variable velocity moving load along an arbitrary trajectory
A combined plate element is presented for the analysis of transverse and longitudinal vibrations of a thin plate which carries a load moving along an arbitrary trajectory with variable velocity. Depending on the acceleration of the point load on its trajectory on the plate surface, the combined element, which is a combination of the 24 DOF plate element and

11. General exact harmonic analysis of in-plane timoshenko beam structures
The exact solution for the problem of damped, steady state response, of in-plane Timoshenko frames subjected to harmonically time varying external forces is here described. The solution is obtained by using the classical dynamic stiffness matrix (DSM), which is non-linear and transcendental in respect to the excitation frequency, and by performing the harmon

12. Panorama de propriedade intelectual, transferência de tecnologia e inovação da química brasileira e a comparação com os países do BRIC
Based on Science, Technology & Innovation (ST&I) indicators, Brazil is a competitive and interesting country from the point of view of technological foreign investment. However, it is still incipient with regard to national investments, production of technological knowledge, inbound mobility of scientists and technology transfer to the productive sector. Amo
