1. Behaviour of hollow circular section with multiple perforations under compression, flexure and torsion
Abstract Effect of the presence of perforations on thin structure has been extensively investigated for decades. Various perforation parameters were investigated in past studies. However, study on thin cylinder with multiple perforations has not been carried out. In searching for lighter structural members, the concept of perforated hollow section has been i

2. Cryptococcal pathogenic mechanisms: a dangerous trip from the environment to the brain
Cryptococcus neoformans is an opportunistic pathogenic yeast that causes serious infections, most commonly of the central nervous system (CNS). C. neoformans is mainly found in the environment and acquired by inhalation. It could be metaphorically imagined that cryptococcal disease is a “journey” for the microorganism that starts in the environment, wher

3. Rolling Contact Fatigue Life of Rail for Different Slip Conditions
Abstract A three-dimensional elastic-plastic finite element analysis (FEA) is carried out to estimate the rolling contact fatigue (RCF) crack initiation life for varied slip range on the rail arising from operational variations. The wheel load produces Hertzian contact pressure. Variation in engine traction induces slip variations that evolves thermal load i

4. Effect of different composite core materials on fracture resistance of endodontically treated teeth restored with FRC posts
Abstract Objective This study evaluated the fracture resistance of endodontically treated teeth restored with fiber reinforced composite posts, using three resin composite core build-up materials, (Clearfil Photo Core (CPC), MultiCore Flow (MCF), and LuxaCore Z-Dual (LCZ)), and a nanohybrid composite, (Tetric N-Ceram (TNC)). Material and Methods Forty en

5. Relationships between static foot alignment and dynamic plantar loads in runners with acute and chronic stages of plantar fasciitis: a cross-sectional study
BACKGROUND: The risk factors for the development of plantar fasciitis (PF) have been associated with the medial longitudinal arch (MLA), rearfoot alignment and calcaneal overload. However, the relationships between the biomechanical variables have yet to be determined. OBJECTIVE: The goal of this study was to investigate the relationships between the MLA,

6. Improved high-order bending analysis of double curved sandwich panels subjected to multiple loading conditions
For the first time, the bending analysis of a double curved sandwich panel was presented which was subjected to point load, uniform distributed load on a patch, and harmonic distributed loads and was based on a new improved higher order sandwich panel theory. Since the cross-sectional warping was accurately modeled by this theory, it did not require any shea

7. Segmented corpus callosum diffusivity correlates with the Expanded Disability Status Scale score in the early stages of relapsing-remitting multiple sclerosis
OBJECTIVE: The aim of this study was to characterize the microscopic damage to the corpus callosum in relapsing-remitting multiple sclerosis (RRMS) with diffusion tensor imaging and to investigate the correlation of this damage with disability. The diffusion tensor imaging parameters of fractional anisotropy and mean diffusivity provide information about th

8. Localização de faltas em linhas de transmissão de múltiplos terminais a partir de registros oscilográficos sincronizados via transformada wavelet
The electric energy is essential to the development of modern society and its increasing demand in recent years, effect from population and economic growth, becomes the companies more interested in the quality and continuity of supply, factors regulated by ANEEL (Agência Nacional de Energia Elétrica). These factors must be attended when a permanent fault o

9. Human Papillomavirus (HPV) infection in HIV positive and negative men: analysis of HPV persistence and histological findings in clinical and sub-clinical lesions / Infecção pelo Papilomavírus Humano (HPV) em homens soropositivos e negativos ao HIV: persistência e relação histológica de lesões clínicas e subclínicas
BACKGROUND: Co-infection with HPV and HIV modifies its natural history and increases the risk of warts and neoplasia development in the anogenital tract. Cohort studies to address HPV infection in the penis are scarce, mainly in HIV infected individuals. METHODS: A longitudinal study, non-probabilistic, was conducted with 144 men of 18 to 70 years old includ

10. Logística reversa de pós-venda para alimentos derivados de carne e leite : análise dos retornos de distribuição
Reverse logistics has conquered more importance and space in the companies logistics operation, mainly for its economic potential, but also for the change in the customers consumption culture and for the increase of the importance of environmental preservation. However, the lack of studies in this direction makes it difficult to visualize the advantages of t

11. Otimização de risco estrutural baseada em confiabilidade / Reliability-based structural risk optimization
In a competitive environment, structural systems must be designed considering not only their function, but also their total costs of construction and operation and their ability to generate profit. The costs are directly linked to the risk resulting from construction and operation of the structure. Risk is defined as the product of failure cost by failure pr

12. ENTRE O URBANO E O RURAL: LIMITES E FRONTEIRAS EM TRASIÇÃO NO MUNICÍPIO DE JUIZ DE FORA
The currently discussion about the borderline can clearly be evidenced by the multiple works developed currently. Its concept loads a diversity of meanings that, identified in distinct historical realities, exceeds the simple idea of the politics landmark between countries, regions or cities. The border-line looked like a territory, express as a cultural spa
