Abstract Raman spectroscopy has been widely used in mineralogy and petrology for identifying mineral phases. Some recent applications of involve measuring the residual pressure inclusions, such as quartz inclusions garnet host, to recover entrapment condition during metamorphism. The crystallographic orientations entrapped host are important know modelling their elastic interaction. However, an...

bacterial leakage and root fractures are the most important reasons of root canal treatment failure. due to the lack of adhesion of gutta percha to the canal walls, resilon has been introduced as a root-filling material able to bond to the root walls. metal posts may predispose the tooth walls to oblique and vertical fracture which usually leads to tooth loss; whereas, fiber posts may reinforce...

This paper presents research on the influence of quartz deformation in aggregates for the development of the alkali-silica reaction in concrete and its relationship with silica dissolution. The study also compares these characteristics with the field behavior of such rocks in concrete. The paper proposes parameters to classify the different degrees of deformation of quartz. Transmission electro...

for the first time, an unusual assemblage of talc-phengite-chlorite-k-feldspar was found in quartz schists from the sanandaj-sirjan zone in the nahavand area in western iran. the talc-bearing quartz schists occur as small bodies or lenses within pelitic schist layers and contain talc, phengite, chlorite, k-feldspar and quartz as major mineral constituents with subordinate amounts of calcite ...

This paper describes an architecture that addresses common problems found in systems supporting QoS specification and enforcement, such as lack of flexibility and expressiveness in the specification of requirements and dependencies on specific platforms. The Quartz QoS architecture aims to solve these problems by adopting a highly extensible and platform-independent design.

The adsorption and speciation of U(VI) was investigated on contaminated, fine grained sediment materials from the Hanford 300 area (SPP1 GWF) in simulated groundwater using cryogenic laser-induced U(VI) fluorescence spectroscopy combined with chemometric analysis. A series of reference minerals (montmorillonite, illite, Michigan chlorite, North Carolina chlorite, California clinochlore, quartz ...
