Relationship between the micromorphology and mechanical properties of semicrystalline polypropylene
… the relationship between processing conditions, micromorphology and mechanical properties of isotactic polypropylene homopolymer using conventional and shear controlled orientation injection moulding (SCORIM) techniques by systematically changing carefully controlled processing conditions, mould …

Relationships between micromorphology and impact properties of injection moulded isotactic polypropylene
The micromorphology and properties of injection moulded semi-crystalline polymers can be significantly modified by changes in the injection moulding parameters and the design of mould. Further modifications to the microstructure and properties occur following the incorporation of additives into a …

MICROMORPHOLOGY AND GENE EXPRESSION IN MUSCLE AND SHELL DEVELOPMENT OF THE MOLLUSCA
This work comprises detailed studies by scanning electron microscopy (SEM), transmission electron microscopy (TEM), fluorescence staining combined with confocal laser scanning microscopy (CLSM), as well as serial sectioning analyses and reconstruction techniques to elucidate the development of the …

Micromorphology of Last Glacial Maximum Grounding line sediments around the Antarctic Peninsula
… the Antarctic Peninsula, were analyzed using micromorphology. This is the first evidence that grounding line sediments from around the Antarctic Peninsula have complex deformational histories and subglacial origins. It was determined that grounding zone wedge contain multiple units, or …

Sedimentology and micromorphology of drumlin sediments at Chimney Bluffs State Park, New York, United States of America
… units within the diamicton. The usefulness of micromorphology in complimenting the traditional sedimentology of glacigenic deposits is emphasised by the current study. An otherwise massive diamicton was shown to contain microstructures indicative of the very high strain rates expected in a …

Human Occupation and Changing Environments During the Middle to Later Stone Ages: Soil Micromorphology at the Haua Fteah, Libya
… percent calcium carbonate) and thin section soil micromorphology to produce a multi-scalar robust site formation history. Through field descriptions and bulk sedimentology, it traces the response of the shelter to global environmental change over the last glacial cycle. Within this long-term …

Living near permanent water in the upper Murray-Darling Basin Implications from the micromorphology of buried soils near artesian springs
… such issues, steep sided gullies (arroyos), soil micromorphology and pedology, and optically stimulated luminescence (OSL) dating provide a framework for the palaeo-human setting. It considers several questions, including: When did landscapes change and why? How did dry and humid conditions effect …

Effects of environmental factors on wood decay micromorphology of Pinus radiata and Fagus sylvatica, and its significance for in-ground wood preservative performance
… microscope (LM) was used to determine decay micromorphology for each treatment (preservative + wood species) at each site and the effects of site, preservative and wood species on preservative performance, decay type and preservative depletion was determined. Suitability of epifluorescent …

Assessing the effects of fluvial abrasion on bone surface modifications using high-resolution 3-D scanning
… tooth marks show that some measurements of the micromorphology of cut marks changed significantly after tumbling, while tooth marks were not significantly altered by tumbling. Additionally, multivariate analysis using the measurements of the micromorphology allowed discrimination between cut …

Studies in the Dryopteris inaequalis (Dryopteridaceae) complex
… Evidence from Scanning Electron Microscopy, micromorphology, macromorphology and cytology is used as a basis for classification. Trichome characters, indusium, spore and guard-cell sizes proved to be of great taxonomic utility in defining species and cytotypes in the complex. Guard-cell and …

Palaeoenvironmental and palaeogeographic reconstruction of the Tequixquiac Basin, Central Eastern Mexico: Mid to late Pleistocene environments
… study, based on the analysis of sedimentology, micromorphology, stable isotopes δ18Ocarbonate and δ13CDIC as well as ICP-OES sediment and tephra geochemistry, LOI, AMS radiocarbon, 40Ar/39Ar and Uranium-series dating has allowed a chronologically constrained paleoenvironmental and …

The Causes and Implications of Microstructures in Glacial Sediments
… Yorkshire, and the subsequent examination of its micromorphology. Shears in the material are disrupted by clasts, and this may be responsible for work hardening seen during the tests. Fabric compression, and the development of immobilised shears or hydraulic fractures buffer pore fluid pressure to …

A Geoarchaeological Investigation of Storage and Surplus at Tel Tsaf, Israel
… big picture debates of the Chalcolithic period. Micromorphology and bulk sediment samples were taken from Building Complexes I, II and IV during the 2006 and 2007 field seasons. Results demonstrate that domestic activities centred in the broadroom house and courtyard of Building Complex I, and …
