[1] During reactive fluid flow in saturated fractures, the relative rates of dissolved mineral transport and local reactions strongly influence local aperture alterations and the resulting changes in fracture permeability (or transmissivity). In the presence of an entrapped residual nonaqueous phase (e.g., CO2 or oil), the spatial distribution of the entrapped phase will influence flow and tran...

Grapefruit (Citrus paradisi Macf.) contain various functional components including flavonones (naringin, narirutin), carotenoids, limonoids (limonin, nomilin, limonoid glucosides), folic acid, aurapatene, and vitamin C. The bitter compounds in grapefruit are naringin (7-β-neohesperidoside of naringenin), limonin, and nomilin. However, narirutin (naringenin 7-β-rutinoside) and limonoid glucoside...

responses to these items, despite the inclusion of the “unable” option, suggests that the activities queried by these items may in fact be less relevant to the study population. In a recent publication by Barley and Jones,2 Rasch analysis was used to assess the measurement properties of the AQ20 over time. Item 3 was found to be unstable due an increase in “not applicable” responses related to ...

Identification and mapping of the significant alterations are the main objectives of the exploration geochemical surveys. The field study is time-consuming and costly to produce the classified maps. Therefore, the processing of remotely sensed data, which provide timely and multi-band (multi-layer) data, can be substituted for the field study. In this study, the ASTER imagery is used for altera...

Remote and extreme regions such as in the Arctic remain a challenging ground for geological mapping and mineral exploration. Coastal cliffs are often the only major well-exposed outcrops, but are mostly not observable by air/spaceborne nadir remote sensing sensors. Current outcrop mapping efforts rely on the interpretation of Terrestrial Laser Scanning and oblique photogrammetry, which have ina...

Biofortification of foods, achieved by increasing the concentrations of minerals such as iron (Fe) and zinc (Zn), is a goal of plant scientists. Understanding genes that influence seed mineral concentration in a model plant such as Arabidopsis could help in the development of nutritionally enhanced crop cultivars. Quantitative trait locus (QTL) mapping for seed concentrations of calcium (Ca), c...

The fast mineral exploration system with remote sensing is a brand new exploration system of recognition, identification, analysis and prediction. It takes metallogenic materials as the detection targets, uses the spectrum measuring technique as detection means and takes the spatial and temporal sequence of mineralization and alteration information as an evaluation basis. It develops and improv...

Processes for formation, cooling, and altering Earth's ocean crust are not yet completely understood due to challenges in access sampling. Here, we use contiguous micro-imaging infrared spectroscopy develop complete-core maps of mineral occurrence investigate spatial patterns the hydrothermal alteration 1.2 km oceanic recovered from Oman Drilling Project Holes GT1A, GT2A, GT3A drilled Samail Op...
