Investigations of lightweight aggregates in Alaska [PDF]
, 1966 Increased construction costs coupled with the current large demand for aggregate materials prompted an investigation by the Mineral Industry Research Laboratory to find deposits of shale suitable for the manufacture of lightweight aggregate near the ...

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Journal of Quaternary Science, EarlyView.Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Examination of Afghanistan's Development Traps
Regional Science Policy &Practice, EarlyView., 2022 Abstract We examine the factors behind Afghanistan's persistent underdevelopment. Drawing on various theories of development traps operating at the demographic, economic and institutional levels, we seek to assess whether and to what extent their functioning affects Afghanistan's development. To capture the functioning of development traps empirically,

Research on shale dynamic and static elastic modulus and anisotropy based on pressurization history
Frontiers in Earth ScienceThe dynamic and static elastic parameters of rocks exhibit differences. It is of great practical significance to carry out experiments on dynamic and static elastic parameters of rocks under reservoir conditions and determine the conversion relationship ...

A review of regional and global estimates of unconventional gas resources [PDF]
, 2012 This Research Report assesses the currently available evidence on the size of unconventional gas resources at the regional and global level. Focusing in particular on shale gas, it provides a comprehensive summary and comparison of the estimates that ...

Journal of Quaternary Science, EarlyView.ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Journal of Raman Spectroscopy, EarlyView.Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman
