1. Characterization of Sobradinho landslide in fluvial valley using MASW and ERT methods
Abstract Landslides can substantially impact the fluvial systems, which is why the continuous mapping of their extent, evolution and stability assessment is crucial. However, in such environments, material identification (e.g. colluvium) and subsurface characterization by the methods used for geologic mapping and geotechnical investigation is often a challen

2. Determinants of Arterial Stiffness and Vascular Aging in the Older Adult
Abstract Background: Arterial stiffness (AS) is recognized as an important and independent risk factor for cardiovascular diseases (CVD). Objective: This study was aimed at identifying the main determinants of AS in the elderly. Design and Methods: This was an observational, cross-sectional study of elderly participants. Blood pressure (BP) and parameters

3. Numerical study of upstream disturbances on the performance of electromagnetic and ultrasonic flowmeters
ABSTRACT Electromagnetic and ultrasonic flowmeters are high precision devices that can measure the water flow in pressurized irrigation networks. In these networks, the inadequate installation distance of flow control valves generates upstream disturbances which will increase measurement errors and reduce the accuracy of the equipment. Therefore, estimating

4. Higher values of triglycerides:HDL-cholesterol ratio hallmark disease severity in children and adolescents with sickle cell anemia
Dyslipidemia has been described in sickle cell anemia (SCA) but its association with increased disease severity is unknown. Here, we examined 55 children and adolescents with SCA as well as 41 healthy controls to test the association between the lipid profiles in peripheral blood and markers of hemolysis, inflammation, endothelial function, and SCA-related c

5. TALENTO MOTOR E MATURAÇÃO BIOLÓGICA EM ESCOLARES DE UM COLÉGIO MILITAR
RESUMO Introdução A avaliação do desempenho motor em escolares tem sido utilizada na identificação de talentos esportivos. Porém, existem poucos estudos, sobre esta temática, e nenhum no Sistema Colégio Militar do Brasil. Objetivo Avaliar indicadores antropométricos, fisicomotores e maturacionais; investigar a proporção de talentos motores; ana

6. Are experienced and high-level race walking athletes able to match pre-programmed with executed pacing?
The objective of this study was to verify the agreement between pre-programmed and executed pacing during race walking and whether level of the athletes experience and performance influenced this relationship. Twenty-nine national and international race walkers participated in this study (14 males, 24.0±7.1 years old, and 15 females, 23.3±7.3 years old). P

7. Clinical and functional variables can predict general fatigue in patients with acromegaly: an explanatory model approach
ABSTRACT Objective To evaluate whether hormonal profile, arterial function, and physical capacity are predictors of fatigue in patients with acromegaly. Subjects and methods: This is a cross-sectional study including 23 patients. The subjects underwent a Modified Fatigue Impact Scale (MFIS) assessment; serum growth hormones (GH) and IGF-1 measurements; pul

10. Xuezhikang reduced arterial stiffness in patients with essential hypertension: a preliminary study
This study aimed to test the effects of xuezhikang, a cholestin extract that contains statin-like components, on arterial stiffness in patients with essential hypertension. One hundred hypertensive patients from the Chinese PLA General Hospital were randomly allocated to receive xuezhikang (1200 mg/day, orally) or placebo (same capsules containing only pharm

11. Performance and Wake Analysis of Rotors in Axial Flight Using Computational Fluid Dynamics
ABSTRACT: Flow field around rotors in axial flight is known to be complex especially in steep descent where the rotor is operating inside its own wake. It is often reported that, in this flight condition, the rotor is susceptible to severe wake interactions causing unsteady blade load, severe vibration, loss of performance, as well as poor control and handli

12. A Phase Ib open label, randomized, safety study of SANGUINATE™ in patients with sickle cell anemia
Abstract Background: Treatment of sickle cell anemia is a challenging task and despite the well understood genetic and biochemical pathway of sickle hemoglobin, current therapy continues to be limited to the symptomatic treatment of pain, supplemental oxygen, antibiotics, red blood cell transfusions and hydroxyurea. SANGUINATE is a carbon monoxide releasing
