1. Barriers to physical activity among adults in primary healthcare units in the National Health System: a cross-sectional study in Brazil
ABSTRACT BACKGROUND: Many factors may negatively impact physical activity (PA), but studies lack evidence of individual predictors of perceived barriers to PA among adults in primary healthcare units. OBJECTIVE: To analyze associations between sociodemographic characteristics, health conditions, leisure-time physical activity (LTPA), PA counseling and perc

2. Phenolic compounds in native potato (Solanum tuberosum L.) cooking water, with potential antioxidant activity
Abstract For over two decades, there has been an increasing interest in finding natural antioxidants, because they can protect the human body from free radicals and retard the progress of many chronic diseases. Phenolic compounds were identified and quantified in potato cooking water from freeze–dried slices with peel and from whole potato stored for 20 d

3. Evaluation of Meat and Egg Traits of Beijing-you Chickens Rotationally Grazing on Chicory Pasture in a Chestnut Forest
ABSTRACT Barn and cage-fed chickens have presented several problems, such as high rates of infectious disease and consequent antibiotic abuse, poorer chicken health and welfare, and often poorer meat and egg quality compared with free-range chickens. The poultry agroforestry system is becoming increasingly popular in many poultry farms nowadays. In this stud

4. Confocal Raman spectroscopy: determination of natural moisturizing factor profile related to skin hydration
INTRODUCTION: Skin health and skin care to reduce the effects of aging are the main interests of many researchers. The skin is very important because it protects the body from various effects of the external environment, and studies of the largest organ of the human body have been conducted since antiquity. In skin, aging effects are severe enough to promote

5. The prostate after administration of anabolic androgenic steroids: a morphometrical study in rats
Purpose Many adverse effects have been associated with abuse of anabolic-androgenic steroids (AAS), including disorders of the urogenital tract. The objective of this study is to analyze the morphological modifications in the prostate ventral lobe of pubertal and adult rats chronically treated with AAS, using morphometric methods. Materials and Methods: We

6. CFD-optimization algorithm to optimize the energy transport in pultruded polymer composites
Pultrusion is a composite manufacturing process in which fibers are pulled continuously through a resin bath for resin impregnation before entering into a heated die, where an exothermic cure reaction occurs. The energy needed to provide the cure reaction depends on many aspects such as cure kinetics and pulling speed. Generally, the pultrusion forming is di

7. Estudo clínico e eletromiográfico de músculos cervicais em mulheres com e sem disfunção temporomandibular / Clinical and electromyographic study of cervical muscles in women with and without temporomandibular dysfunction
The temporomandibular disorder (TMD) among many symptoms causes orofacial pain. It is also common, the incidence of neck pain complaint, which leads to overlapping signs and symptoms of temporomandibular joint (TMJ) and cervical spine. This study aimed to compare the patterns of electromyographic activity and the presence and severity of pain in the cervical

8. Controle de Corrente de Spin em Pontos Quânticos na Presença de Tensões de Porta Moduladas no Tempo
Since Loss &DiVincenzo proposal to use confined electron spins in quantum dots (QDs) as a building block for qubits in solid state systems, spin-dependent transport in QDs has attracted a lot of attention. The interest for this system increased even further with the recent experimental developments to coherently control (initialization-manipulation-read out)

9. Imunodetecção do receptor metabotrópico mGluR8 no núcleo arqueado do hipotálamo de ratos Wistar e estudo dos efeitos, no receptor, resultantes da exposição oral sub-crônica ao glutamato monossódico / Imunodetecction of mGluR8 receptor in the arcuate nucleus of the hypothalamus of Wistar rats and study of the effects, on the receptor, resulting from sub-chronic exposure to monosodium glutamate
Food is part of human culture not only associated to physiological needs. Food is composed of several molecules among them amino acids. Glutamate (GLU) is the anion of one of the main amino acids found in foods that, besides being part of the food composition, is a molecule essential for human physiology. It can also be ingested due to the use of the food ad

10. Aplicação do método de análise de risco ao estudo do descarrilamento. / Aplication of risk analysis method to the derailment study.
This research proposes a risk analysis method applied to derailment event (characterized by the wheel overlap on the rail, which can be caused by many aspects: rail imperfections, rolling stock failures, obstacles etc and which can cause accidents, material and life loss) to increase the safety level on railway transport that actually does not present decrea

11. Transições de fase hádron-quark em estrelas de nêutrons
Recent advances on the field of high energy physics have enabled the study of matter under extreme conditions and, in this context, new states of matter are being discovered and speculated upon. Among these hypothetical states of matter is the one of deconfined quarks in high densities and/or temperatures. An environment with extreme densities and low temper

12. Simulações Monte Carlo de integrais de trajetória : propriedades elásticas do 4He sólido / Path integrals Monte Carlo simulations : elastic properties of 4He
The path-integral Monte Carlo (PIMC) method is a sophisticated approach for the simulation of many-body quantum systems. In particular, it has been extensively used for the study of manybody bosonic systems such as 4He. The main objective of the present dissertation is to apply the PIMC method to determine the elastic constants of solid 4He in its hcp phase.
