1. Predicting urine output after kidney transplantation: development and internal validation of a nomogram for clinical use
ABSTRACT Purpose: To analyze pre-transplantation and early postoperative factors affecting post-transplantation urine output and develop a predictive nomogram. Patients and Methods: Retrospective analysis of non-preemptive first transplanted adult patients between 2001-2016. The outcomes were hourly diuresis in mL/Kg in the 1st (UO1) and 8th (UO8) postoper

2. WATER-BASED EXERCISE AND RESISTANCE TRAINING IMPROVE COGNITION IN OLDER ADULTS
RESUMO Introdução: A prática de exercícios físicos tem sido associada à manutenção das habilidades físicas e redução do declínio cognitivo durante o envelhecimento, sendo considerada uma estratégia de prevenção primária de baixo custo, assim como tratamento não-farmacológico da disfunção cognitiva em idosos. Entretanto, a contribuição

3. Effects of resistance training protocols on nonlinear analysis of heart rate variability in metabolic syndrome
Despite the various standard non-linear measurements used in autonomic modulation (AM) assessments usually being applied to long time-series, such analyses can sometimes be applied to shorter term series. To overcome this disadvantage, chaotic global methods were formulated by putting together heart rate variability (HRV) linear methods. Chaos provides infor

4. Thermogravimetric and spectroscopic study (TG–DTA/FT–IR) of activated carbon from the renewable biomass source babassu
Activated carbons (ACs) with well–developed microstructure and high microporosity were obtained from biomass by potassium hydroxide activation. The preparation process consisted in producing carbon materials in the ratios of activating agent to raw material 70:30, 50:50, 30:70 and 25:75 (w/w) characterized by thermal analysis coupled to spectroscopy (TG–

5. Studies on Growth, Spectral, Thermal, Mechanical and Optical Properties of 4-Bromoanilinium 4-Methylbenzenesulfonate Crystal: A Third Order Nonlinear Optical Material
Abstract 4-Bromoanilinium 4-methylbenzenesulfonate (4BPTS) single crystal was successfully grown from ethanol by slow evaporation method at room temperature. The structure of grown crystal was confirmed by single crystal X-ray diffraction studies. The presence of functional groups of grown crystal was confirmed by the Fourier transform infrared spectroscopy

6. Analysis on the Growth and Characterization of a Non-linear Optical Single Crystal: L-Cystine Dihydrobromide
Nonlinear optical single crystals of L-cystine dihydrobromide (LCHB) have been grown by slow evaporation method. Single crystal X-ray diffraction analysis revealed the crystal system and lattice parameter values. Powder X-ray diffraction analyses have been carried out and the diffraction patterns have been indexed. Fourier transform infrared (FTIR) analysis

7. Estimação e previsão da estrutura a termo das taxas de juros usando técnicas de inteligência computacional / Term structure of interest rate modeling and forecasting using computational intelligence techniques
This work proposes the term structure of interest rates modeling and forecasting using computational intelligence techniques, based on data from the US and Brazilian fixed income markets. The yield curve modeling includes the use of some evolutionary computation methods like Genetic Algorithms, Differential Evolution and Evolution Strategies in comparison wi

8. Alterações metabólicas cerebrais associadas aos fatores de risco cardiovascular: um estudo de tomografia por emissão de pósitron (PET) / Abnormalities on brain metabolism associated to cardiovascular risk factors: a positron emission tomography (PET) study
INTRODUCTION: Cardiovascular risk factors (CVRF) are known to affect cerebral blood flow, possibly contributing to cognitive decline and to the emergence of Alzheimers disease (AD), the commonest form of dementia. Positron emission tomography (PET) with 18-fluoro-2-deoxyglucose (18FFDG) has been widely used to demonstrate specific patterns of reduced brain g

9. Hypertextuality: a hypertexts-enunciative approach / Hipertextualidade: uma abordagem enunciativa de hipertextos
This research aims to analyze the criteria by which hypertext is defined and verify if the criteria are applied to hypertext or to hypertextuality, expressions that are puzzled in the literature about the subject, above all in Textual Linguistics scope. We verified that the definition of hypertext is based on a single criterion sometimes, and on an excessive

10. Contribuições na teoria de otimização para alguns problemas de programação infinita e de programação com tempo continuo / Contributions in the optimization theory for some infinite programming problems and continuous time programming problems
In this thesis work it is regarded two type of abstract optimization problems. The _rst one corresponds to the in_nite programming problem. A such problem consists in minimizing a functional subject to an in_nite number of constraints, where the functions involved are dened in a Banach space. The second one is the continuous time programming problem, which c

11. VIBRATION CONTROL OF SLENDER TOWERS WITH A PENDULUM ABSORBER / ABSORSOR PENDULAR PARA CONTROLE DE VIBRAÇÕES DE TORRES ESBELTAS
In the present work the performance of a pendulum absorber in the vibration control of tall and slender towers, caused by dynamic loads, such as, environmental loads, is studied in detail. Due to the possibility of large amplitude oscillations, the non-linearity of the pendulum is considered in the modeling of the problem. The main objective of this research

12. Set-valued functions / Funções ponto a conjunto
We study a mapping called a set-valued map which associates with each point of a metric space a non empty subset of another metric space. In the case of single-valued maps, contin-uous functions are characterized by two equivalent properties: one in terms of neighborhood and other in terms of sequences. These two properties can be adapted to the case of set-
