1. Finite Element Investigation of Performance of Composite-Steel Double Lap Adhesive Joint Under Tensile Loading
Abstract Parametric study of composite-steel double lap joint under tensile loading is performed using finite element modeling. The joint is such that steel is placed between a straight and a curved composite sublaminate. Three joint characteristics including maximum Von Mises stress in adhesive layer, stiffness and weight are investigated. Design curves are

2. Distrofia muscular de cinturas em crianças brasileiras: caracterização clínica, histologia e molecular
Limb-girdle muscular dystrophies (LGMD) are a heterogeneous group of genetic muscular dystrophies, involving 16 autosomal recessive subtypes and eight autosomal dominant subtypes. Autosomal recessive dystrophy is far more common than autosomal dominant dystrophy, particularly in children. The clinical course in this group is characterized by progressive prox

3. NAA and NAAG variation in neuronal activation during visual stimulation
N-acetyl-aspartyl-glutamate (NAAG) and its hydrolysis product N-acetyl-L-aspartate (NAA) are among the most important brain metabolites. NAA is a marker of neuron integrity and viability, while NAAG modulates glutamate release and may have a role in neuroprotection and synaptic plasticity. Investigating on a quantitative basis the role of these metabolites i

4. Análise da influência de diferentes razões de sobreposição no desempenho de turbinas eólicas Savonius empregando dinâmica dos fluidos computacional / Analysis of the influence of different overlap ratios on savonius wind turbines performance using computational fluid dynamics
Este trabalho consiste na análise da influência de diferentes razões de sobreposição das pás no desempenho de turbinas eólicas Savonius. A análise é feita utilizando a dinâmica dos fluidos computacional. Utiliza-se o software comercial Star-CCM+ para a solução das equações da continuidade e de Navier-Stokes com médias de Reynolds. Essas equaç

5. Characterization of the interdependency between residues that bind the substrate in a β-glycosidase
The manner by which effects of simultaneous mutations combine to change enzymatic activity is not easily predictable because these effects are not always additive in a linear manner. Hence, the characterization of the effects of simultaneous mutations of amino acid residues that bind the substrate can make a significant contribution to the understanding of t

6. Phenomenological analysis of proton-proton and antiproton-proton elastic scattering at high energies / Analise fenomenologica dos espalhamentos elasticos proton-proton e antiproton-proton em altas energias
We present a study on proton-proton (pp) and antiproton-proton (¯pp) elastic scattering at high energies, with focus on the behavior of the total cross section, differential cross section and the parameter p (ratio between the real and the imaginary parts of the forward amplitude). These quantities are described by means of a model independent parametrizati

7. A promoção da saúde e as pólíticas de saúde bucal do Distrito Federal
With the implementation of the Unified Health System of Brazil, health promotion has become an important strategy for improving the health of the population, particularly, in the oral health field. Being thus, the priority actions of promotion in this field enclose community educative-preventive activities. The purpose of this study was to analyze the oral h

8. Analise da variabilidade da frequencia cardiaca em mulheres na pos-menopausa sedentarias e treinadas
The aim of this survey was to analyze and compare the magnitude of the cardiac autonomic activity of women in the one after menopause during the conditions of vigil in rest (VIG) and sleep (SLEEP) through heart rate variability (HRV). Fifteen postmenopausal women were studied, all of them users of Hormone Replacement Therapy (HRT) considered clinically healt

9. Calcium alone does not fully activate the thin filament for S1 binding to rigor myofibrils.
Skeletal muscle contraction is regulated by calcium via troponin and tropomyosin and appears to involve cooperative activation of cross-bridge binding to actin. We studied the regulation of fluorescent myosin subfragment 1 (fS1) binding to rigor myofibrils over a wide range of fS1 and calcium levels using highly sensitive imaging techniques. At low calcium a

10. Application of Bayes' theorem to the diagnosis of ankylosing spondylitis from radioisotope bone scans.
The ratio of the uptake of radioactivity in each sacroiliac joint to the uptake in the sacrum has been measured in 57 patients with early ankylosing spondylitis and in 51 control subjects. The distribution of ratios of uptake obtained in each of these two groups shows appreciable overlap, and it is shown that the specification of a 'normal range' in this sor

11. Fingers as a Marker of Prenatal Androgen Exposure
Interest in biological substrates of sex-related variations in psychological and physiological characteristics has led to a search for biomarkers of prenatal hormone exposure that can be measured postnatally. There has been particular interest in digit ratio, the relative lengths of the second and fourth fingers (2D:4D), but its validity as a measure of pren

12. Is serum creatine kinase:aspartate aminotransferase ratio useful for diagnosing acute myocardial infarction in elderly patients?
AIM: To evaluate the usefulness of the serum creatine kinase: aspartate aminotransferase (CK:AST) ratio in differentiating between myocardial and non-myocardial increases in serum creatine kinase activity in the elderly. METHODS: A three month prospective study of all patients admitted to an acute geriatric unit who were clinically assessed and investigated
