Architectural ornaments, used as decorative elements, are made of stone; but most of their components contain gypsum. It is found that the deterioration of ornaments is attributed to water penetration, biological colonization, micro and macro cracking and partial and (or) complete detachment from their supports. Many rehabilitation operations of architectural ornaments have failed to use the appropriate material for the needs of the project. The use of construction waste, particularly used brick, is currently widespread for such operations. For an efficient and sustainable use of these materials, an experimental study was conducted to investigate the influence of the content of waste brick on the physical and mechanical properties of gypsum mortar. The main variables in this study being the waste brick content and the substrate type. The Water/Mortar ratio of all mixes was kept constant to maintain a similar level of workability. Numerous tests were performed to evaluate the physical and mechanical behavior of the gypsum mortars, including bond test, X-ray and SEM analysis. The results obtained show that the bond strengths of the mortars are greater when the substrate is made of limestone compared to the substrate made of bricks. However, an excessive percentage of brick waste in the mortar can have negative effects and reduce the bond strength. Plaster mortars made with 75% waste brick should be recommended for the rehabilitation of architectural ornaments. [ABSTRACT FROM AUTHOR]

Purpose: The transfer of data to the laboratory remains the key to the success of hybrid implant supported prosthesis. The impression represents the preliminary step of this procedure. It is important to establish a protocol that is appropriate to the clinical situation from implant placement to insertion of the prosthesis into the mouth. Materials and Methods: This article develops 4 case reports, each with a different recording procedure. Results: Plaster remains the material of choice when precision is required. The Novum system has the advantage of not requiring an impression but its indication remains very limited. [ABSTRACT FROM AUTHOR]

Cutmarks on the bones of ten individuals from Körtik Tepe, a Pre-Pottery Neolithic site in Southeastern Anatolia, were analysed using a bioarchaeological approach. Half of the ten individuals possess cutmarks on their crania only while the other five have cutmarks on both their cranial and postcranial bones. Diagnoses of these cutmarks suggest they were made on fresh cadavers, while skeletal data and burial customs reveal that the individuals with cutmarks were subject to human intervention in the decomposition process, understood as post-burial practices rather than secondary burials. This conclusion is supported by the application of plaster and paint as part of the burial customs. The process of defleshing is interpreted as an attempt to purify the corpse and to separate death from life. [ABSTRACT FROM AUTHOR]

Divergent dislocation of the elbow is a severe injury leading to a significant amount of soft tissue stripping. Achieving a good functional outcome following this injury remains a challenge. We present a case report which was managed conservatively in a cast brace and achieved satisfactory functional results. To our knowledge, this method of treatment has not been described in the English literature. [ABSTRACT FROM AUTHOR]
