Stress shielding and amplification in alveolar cortical-cancellous bone fractures: An analysis of implant-bone stress interactions

The effectiveness of dental implants greatly relies on the attainment of osseointegration and the sustained stability of the implant in the long run.  An essential factor in achieving this success lies in comprehending the shift from primary to secondary stability and the consequences of microcracks that occur during the drilling of alveolar bone before implantation.  The objective of this study is to examine the stress interactions occurring in double-edge parallel cracks within heterogeneous (cortical-cancellous) bone under different loading conditions, particularly m

The automated system of mathematical calculations of acoustic and elastic properties of rocks from the ultrasound measurements

The automated system of numerical analysis and visualization of these ultrasonic measurings of anisotropy parameters of velocities of elastic quasi-longitudinal, "fast" and "slow" quasi-transversal waves in rocks is offered. The effects of anisotropy parameters of rock-collectors are explored from the ultrasound results measurements for the complicated tense-deformed conditions. Orthorhombic type of acoustic anisotropy is discovered for rock specimens this is determined with texture, composition and rocks compound-ordered microfracturing.
