A pertographic and geochemical study of selected peridotitic and pyroxenitic xenoliths from the three kimberlite localities in the Lac de Gras region, Northwest Territories, Canada
… A petrographic study of the xenoliths using both transmitted light microscopy and binocular microscopy was followed by major anti trace element analysis. Major element compositions of individual minerals were determined using a wavelength dispersive electron microprobe, and trace element …

Characterization of dispersive and distributive mixing in a co-rotating twin-screw compounding extruder
… calcium carbonate filler using reflected light microscopy on polished surfaces, and transmitted light microscopy of microtomed pigmented sections. Stereological statistics have been applied to raw sample data; results are discussed in relation to mechanistic phenomena influencing particle …

The chemical characterisation of authigenic carbonates from the Witbank no. 2 coal seam : environmental and diagenetic implications
… analysis, vitrinite reflectance, reflected and transmitted light microscopy, scanning electron microscopy and electron microprobe analysis. Comparison with the studies of Matsumoto and Iijima (1981), Curtis and Coleman (1986) and other literature showed the Witbank carbonates to have followed a …

Relationship between the micromorphology and mechanical properties of semicrystalline polypropylene
… of analytical methods were employed. Optical transmitted light microscopy was used to reveal the skin-core morphology and preferentially oriented fibrous textures. Transmitted Electron Microscopy represented the enlargement of the fibrous alignment. Micro hardness analysed the hardness and …

The Geobiology of the Paleoproterozoic Belcher Group, Nunavut, Canada
… Previous characterization of the BGM utilized transmitted light microscopy. This thesis further investigates the BGM by utilizing other methods including Raman spectroscopy, X-ray photoelectron spectroscopy, and both electron microprobe and scanning electron microscopy, in addition to …

A study on the role of oxidative stress and protein kinase signalling in hyperglycaemia induced cardiac remodelling
… and beating characteristics were observed using transmitted light microscopy. Immunocytochemistry and fluorescence microscopy imaging was used to detect changes in biomarkers. The nuclear uptake of propidium iodide (PI) was used to evaluate cell viability, whereas the 5-ethynyl-1- deoxyuridine …

Diagenetic controls on porosity, thermal history, and hydrocarbons in the Wolfcamp A, eastern Midland Basin, Texas
… and the controls on carbonate macroporosity. Transmitted-light microscopy, UV-epifluorescence, cathodoluminescence, and SEM-EDS microscopy, as well as δ18O, δ13C, 87Sr/86Sr, and fluid inclusion analyses were performed. The diagenetic history could be divided into stages: Early Stage occurred …

Permeability, Pore Body, and Pore Throat Size Distributions from 2D Image Analysis: Comparison with Results from 3D Imaging and Laboratory Measurements
Quantifying rock and fluid properties is essential for characterizing any petroleum bearing reservoir. Typically, this requires that core be acquired from the formation of interest. Core plug samples are then drilled for rock properties measurement. In order to cut costs, percussion sidewall core …
