1. Suicide detection in Chile: proposing a predictive model for suicide risk in a clinical sample of patients with mood disorders
Objective: To analyze suicidal behavior and build a predictive model for suicide risk using data mining (DM) analysis. Methods: A study of 707 Chilean mental health patients (with and without suicide risk) was carried out across three healthcare centers in the Metropolitan Region of Santiago, Chile. Three hundred forty-three variables were studied using fi

2. Effects of different frequencies of transcutaneous electrical nerve stimulation on venous vascular reactivity
Transcutaneous electrical nerve stimulation (TENS) is a type of therapy used primarily for analgesia, but also presents changes in the cardiovascular system responses; its effects are dependent upon application parameters. Alterations to the cardiovascular system suggest that TENS may modify venous vascular response. The objective of this study was to evalua

3. TECENDO A IGUALDADE : REFLEXÕES SOBRE GÊNERO E TRABALHO NA REDE DE ECONOMIA SOLIDÁRIA EM DOURADOS-MS (2000-2008)
This thesis aims to study women contribution to the Rede de Economia Solidária (the Solidarity Economy Network) of Dourados-MS since the year 2000. This discussion is guided on the theoretical framework of gender, which allows reflection on power relations and social inequalities based on gender. Stereotypes historically created from women biological defini

4. Imagens da libertação: a relação entre práxis política, transformação social e arte na teoria crítica de Herbert Marcuse
The objective of this study is to demonstrate that the relationship between social change and art is present throughout the work of Herbert Marcuse and undergoes changes in the way the author to develop over his intellectual trajectory. Moreover, evidence that social transformation requires a change in the consciousness of the individual. The art, preserving

5. Metodologia de estimação de parâmetros de sistemas dinâmicos não-lineares com aplicação em geradores síncronos / Parameter estimation methodology of dynamical nonlinear systems with application in synchronous generators
Este trabalho apresenta uma nova metodologia para estimar parâmetros de geradores síncronos baseada na análise de sensibilidade de trajetória. Esta nova metodologia foi concebida com o objetivo de suplantar dificuldades de convergência que a metodologia de sensibilidade de trajetória tradicional apresenta devido a: (i) baixa robustez com relação aos

6. Trajectory planning of jumping over obstacles for hopping robot
Trajectory planning strategy is proposed to jump over an obstacle integrated three various dynamics in one-legged multi-joint hopping robot. A concept of inertia matching ellipsoid and directional manipulability are extended to optimize take-off postures. Optimized results have been used to plan hopping trajectory. Aimed at the sensitivity of motion trajecto

7. Estimação dos parâmetros da máquina síncrona e seu sistema de excitação / Estimation of the parameter of synchronous machine and its excitation system
In this work a methodology to estimate parameters of synchronous machines and their excitation system based on trajectory sensitivity technique and system synchronization is proposed. Many methodologies for parameter estimation have been proposed in the literature, each one with advantages and desadvantages. However, only some of them are adequate to estimat

8. Selective depression of motion sensitivity during saccades.
1. Horizontal gratings flashed for 20 ms were used to compare visual contrast sensitivity during horizontal saccades with sensitivity during normal vision, at three luminance levels, 4 X 10(2), 4 X 10(-2), and 4 X 10(-4) cd/m2. 2. Greatest sensitivity loss during saccades was found at low spatial frequencies. There is little or no loss at high spatial freque

9. Cytosolic calcium and myofilaments in single rat cardiac myocytes achieve a dynamic equilibrium during twitch relaxation.
1. Single isolated rat cardiac myocytes were loaded with either the pentapotassium salt form or the acetoxymethyl ester (AM) form of the calcium-sensitive fluorescent probe, Indo-1. The relationship of the Indo-1 fluorescence transient, an index of the change in cytosolic calcium [Ca2+]i concentration, to the simultaneously measured cell length during the el

10. Broadband relaxation-optimized polarization transfer in magnetic resonance
Many applications of magnetic resonance are limited by rapid loss of spin coherence caused by large transverse relaxation rates. In NMR of large proteins, increased relaxation losses lead to poor sensitivity of experiments and increased measurement time. In this article, we develop broadband relaxation-optimized pulse sequences that approach fundamental limi

11. Single-particle tracking for DNA tether length monitoring
We describe a simple single-particle tracking approach for monitoring the length of DNA molecules in tethered particle motion experiments. In this method, the trajectory of a submicroscopic bead tethered by a DNA molecule to a glass surface is determined by videomicroscopy coupled to image analysis. The amplitude of motion of the bead is measured by the stan

12. A 5-nanosecond molecular dynamics trajectory for B-DNA: analysis of structure, motions, and solvation.
We report the results of four new molecular dynamics (MD) simulations on the DNA duplex of sequence d(CGCGAATTCGCG)2, including explicit consideration of solvent water, and a sufficient number of Na+ counterions to provide electroneutrality to the system. Our simulations are configured particularly to characterize the latest MD models of DNA, and to provide
