[1] Study of bulk nitrogen contents and isotopic composition in Arctic Ocean sequences (Integrated Ocean Drilling Program Expedition 302) over the past 60 Ma revealed changes in the export flux and sources of sedimentary nitrogen. The paleoproductivity calculated from the fraction of organic nitrogen to total nitrogen is distinctly lower (<20 g C m 2 a ) during the ice-covered Neogene compared ...

STUDY DESIGN An in vitro biomechanical study of adjacent segment motion (at L3-L4 and L5-S1) after a simulated lumbar interbody fusion of L4-L5 in different sagittal alignments was carried out. OBJECTIVES To test the hypothesis that an L4-L5 fixation in different sagittal alignments causes increased angular motion at the adjacent levels (L3-L4 and L5-S1) in comparison with the intact spine. ...

Internal fixation with a Gamma nail, in its short and long versions, is an excellent surgical technique for intertrochanteric and subtrochanteric fractures of the femur. A stable osteosynthesis is obtained which allows early mobilisation and promotes healing of the fracture. However, it is not free from complications; many of them are due to poor surgical technique and/or inadequate monitoring....

This paper focuses on the probabilistic numerical solution of the problems in biomechanics and mining. Applications of Simulation-Based Reliability Assessment (SBRA) Method are presented in the solution of designing of the external fixators applied in traumatology and orthopaedics (these fixators can be applied for the treatment of open and unstable fractures etc.) and in the solution of a hard...
