A major degradation scenario within safety assessment analysis of nuclear waste repositories is decalcification of cementitious materials due to long-term contact with groundwater. Understanding the changes in Physical and Chemical properties of cementitious barriers is of high importance. In order to decrease the uncertainty in the assessments due to extrapolating short term data sets, acceler...

Decalcification is routinely performed for histological studies of bone-containing tissue. Although DNA in situ hybridization (ISH) and comparative genomic hybridization (CGH) have been successfully employed on archival material, little has been reported on the use of these techniques on archival decalcified bony material. In this study we compared the effects of two commonly used decalcifiers,...

Managing non cavitated dental carious lesions non-invasively through remineralisation agents is a main goal and attempt to prevent further carious progression, and to improve and maintain the form and function of the teeth and oral cavity. The application of remineralisation agents to the non cavitated lesions has led to the development of novel technologies to arrest the further carious progre...

Heavily calcified annuli increase the incidence of complications after prosthetic valve replacement-heart block, separation of the aorta or the atrium from the ventricle, late aneurysm formation, paravalvular leak, and haemolysis. An ultrasonic calculus-disintegrator has been developed to remove calcific deposits. The instrument is portable, robust, easily sterilized, inexpensive, and provides ...

Case 1-A girl aged eleven years was admitted in January 1946 with a history of five weeks’ lower thoracic pain and fever followed by the formation of an abscess in the temporo-mandibular region. There was rigidity of the spine with tenderness over the upper lumbar spinous processes. Radiographs showed decalcification of the ninth and tenth thoracic vertebrae with diminution of the intervertebra...
