16. Diagenesis and Reservoir-Quality Evolution of Deep-Water Turbidites: Links to Basin Setting, Depositional Facies, and Sequence Stratigraphy
Abstract : A study of the distribution of diagenetic alterations and their impact on reservoir-quality evolution in four deep-water turbidite successions (Cretaceous to Eocene) from basins in active (foreland) and passive margins revealed the impact of tectonic setting, depositional facies, and changes in the relative sea level. Diagenetic modifications encountered in the turbiditic sandstones from the passive margin basins include dissolution and kaolinitization (kaolin has δ18OV-SMOW = +13. READ MORE

17. Total knee arthroplasty : Alternative aspects on fixation, design and postoperative treatment
Abstract : Total knee arthroplasty as a treatment of severe gonarthrosis has become a great success, but tibial component loosening is still a major reason for failure. When total knee arthroplasty was introduced, only all-polyethylene (AP) tibial components were available. READ MORE

18. Portland Cement Clinker - Composition and Hydration
Abstract : The crystal structures of the main Portland cement clinker phases are reviewed and two anion centered models of Ca3SiO5 and Ca2SiO4 are presented. The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. READ MORE

19. Phase development, heat of hydration and expansion in a blended cement with b-hemihydrate and anhydrite as calcium sulfate
Abstract : Expansive cements are utilised in special applications to improve properties such as cracking caused by drying shrinkage. Several types of expansive cements exist and the main hydration product responsible for the expansion is ettringite, [Ca3Al(OH)6]2(SO4)3·26H 2O. READ MORE

20. Silicon nitride-based materials for spinal and antipathogenic applications
Abstract : Silicon nitride (Si3N4) is a ceramic material that is well-established in industrial applications due to its stability in demanding environments. The mechanical properties and biocompatibility of the material have led to its approval for clinical use in spinal implants. READ MORE
