CLEARCUT PYROXMANGITEhlHODONITE OCCILJRRENC:E, GREENWOOD AREA, SOUTHERN’ BRITISH COLUMBIA (82.1E2)
This report describes a new pyroxmangite-rhodonite occurrence visited briefly by the authors as part of a broader study o,f gemstones in British Columbia. The discovery is on the Cl-t claims, 1.5 kilometres northwest of Mount Roderick Dhu (lat. 49”12’, long. 118’37’), 13 kilometres northeasi of Greenwood (Figure 1). Rhodonite is a manganiferous semiprecious stone valued for its pink to deep red...
متن کاملSupersymmetry for Alp Hikers
These lectures provide a phenomenological introduction to supersymmetry, concentrating on the minimal supersymmetric extension of the Standard Model (MSSM). In the first lecture, motivations are provided for thinking that supersymmetry might appear at the TeV scale, including the naturalness of the mass hierarchy, gauge unification and the probable mass of the Higgs boson. In the second lecture...
متن کاملRaman spectroscopy of the mineral rhodonite.
The mineral rhodonite an orthosilicate has been characterised by Raman spectroscopy. The Raman spectra of three rhodonites from Broken Hill, Pachapaqui and Franklin were compared and found to be similar. The spectra are characterised by an intense band at around 1000 cm(-1) assigned to the nu(1) symmetric stretching mode and three bands at 989, 974 and 936 cm(-1) assigned to the nu(3) antisymme...
متن کاملEvaluation of Alkaline phosphatase (ALP) and Heat Stable- ALP (HS-ALP) in Chronic Obstructive Pulmonary Disease (COPD)
Background: COPD (Chronic Obstructive Pulmonary Disease) is defined as a disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually both progressive and associated with an abnormal inflammatory response of the lungs to noxious particles and gases. Tobacco smoke remains the main etiological agent. COPD inflammation initiated by tobacco smoke...
متن کاملDifferential Properties of Human ALP+ Periodontal Ligament Stem Cells vs Their ALP- Counterparts
Characterizing subpopulations of stem cells is important to understand stem cell properties. Tissue-nonspecific alkaline phosphatase (ALP) is associated with mineral tissue forming cells as well as stem cells. Information regarding ALP subpopulation of human periodontal ligament stem cells (hPDLSCs) is limited. In the present study, we examined ALP+ and ALP- hPDLSC subpopulations, their surface...
