This review is concerned with some key features observed within grouped samples of ancient ceramics that provide important evidence concerning the selection appropriate raw materials and evolution firing technologies employed in their production. It also demonstrates importance distinguishing accounting for mineralogical microstructural attributes identifying processes responsible these ceramic...

Objective: The applications of single-structure fiber-reinforced composite (FRC) in restorative dentistry have not been well reported. This study aimed to clarify the static mechanical properties of anterior crown restorations prepared using two types of single-structure FRC. Materials and methods: An experimental crown restoration was designed for an upper anterior incisor. The restorations we...

Glacial sediment research using thin sections began post-1945. Microsedimentology examines sediments at the microscopic level deriving insights into processes of glacial erosion, transport, and deposition. Two issues exist (1) difficulty by some in recognizing microstructures section (2) absence quantitative data making reproduction difficult. The latter is hard to resolve but more image captur...

Recent investigations of an apparently ‘empty,’ partly disturbed Viking chamber grave in Denmark (Fregerslev II, dated around the mid-10th century CE) provided opportunity to develop a novel multi-scale and multi-method analysis burial post-burial processes. To overcome limitations poor preservation artefacts bones, lack clear macrostratigraphic sequence, we integrated multi-proxy analyses orga...

The peculiar characteristics of dust toxicity are discussed in relation to the processes taking place at the particle-biological medium interface. Because of surface reactivity, toxicity of solids is not merely predictable from chemical composition and molecular structure, as with water soluble compounds. With particles having the same bulk composition, micromorphology (the thermal and mechanic...
