1. Controversies in the treatment of postmenopausal osteoporosis: How long to treat with bisphosphonates?
ABSTRACT Osteoporosis is a systemic skeletal disease characterized by reduced bone mass and deterioration of bone tissue microarchitecture leading to an increased risk of fractures. Fragility fractures, especially hip fractures, are associated with a significant reduction in the physical function and quality of life of affected patients, as well as increased

3. Post-elastic Deformation Characteristics of Hybrid Fibre Reinforced Concrete Composites
Abstract The present study was focused on evaluating the strength and failure properties of hybrid micro-fibre concretes containing micro brass and steel fibre additions. Experimental tests were conducted on different hybrid fibre concretes containing aligned fibres in the direction of beam axis and the relative mechanical performance was compared to randoml

7. Fatigue failure analysis of HSLA steel sheets holed by conventional and flow drilling processes
RESUMO O processo de furação por escoamento produz buchas para uniões removíveis que podem ser roscadas pelo processo de rosqueamento por conformação, reduzindo etapas da produção de componentes da indústria automobilística e em galpões da construção civil. Aços de alta resistência e baixa liga (ARBL) são empregados em variadas aplicações n

8. PM versus IM Ti-5Al-5V-5Mo-3Cr Alloy in Mechanical Properties and Fracture Behaviour
The comparisons of mechanical properties and fracture behaviour between as-consolidated PM Ti-5553 alloy and as-cast IM Ti-5553 alloy were investigated through tensile, fracture toughness and impact toughness tests in this research. The slightly higher strength but much higher ductility and toughness can be identified in IM alloy specimens, which is also con

9. Fatigue failure analysis of HSLA steel sheets holed by conventional and flow drilling processes
ABSTRACT Flow drilling process produces bushes for removable joints that can be threaded by forming tapping process, reducing stages in production of components of automobile industry and in construction sheds. High strength and low alloy steels (HSLA) are employed on several applications in the processing industry. Benefits provided by these materials make

10. Investigation of the Roof Presplitting and Rock Mass Filling Approach on Controlling Large Deformations and Coal Bumps in Deep High-Stress Roadways
Abstract Roadway deformation and coal bumps are major challenges for underground engineering. Taking the Lu'an mining district in Shanxi Province as an example, the failure mechanism of deep high-stress roadway was studied. Numerical simulations and the similar material test were performed to investigate the effect of the roof presplitting and rock mass fill

12. Study of cracks in concrete target under deep penetration by a projectile
Abstract A large number of cracks occur in concrete structure after projectile penetration. The study of crack distribution and propagation process is the basis of damage assessment, structural repair and high dynamic fracture mechanism. In this paper, wire saw cutting, X-ray computed tomography (X-CT) and mechanical property testing of damaged concrete were
