- Abstract:
- ... The timing of wolf domestication remains a subject of intense debate, especially as recent genetic, morphological and radiometric analyses of relevant skeletal material apparently demonstrate the presence of canids on Eurasian Early Upper Palaeolithic sites to be more widespread than previously envisaged. However, numerous questions still surround wolf domestication, not least of which is satisfac ...

- Abstract:
- ... X-ray fluorescence and X-ray radiometry represent easy and simple methods to determine concentrations of heavy metals in the ash of peat soils contaminated with oil and can be applied for soil monitoring purposes. Oil spills on peat bogs produce two contamination zones differing in the composition of heavy metals. In the zone of primary contamination, the peat surface is covered by a bitumen crust ...

- Abstract:

Applications of terrestrial laser scanning (TLS) to measure soil erosion are yet limited, although this topographic mapping method allows for large area coverage with high resolution and reliable precision. However, restricting factors are accurate and stable references for multi-temporal change detection and adverse scanning geometries. At agricultural fields the plot is usually situated on gentl ...

The common CK2 substrate peptide RRRDDDSDDD, conjugated with the fluorophore 5-[(2-aminoethyl)amino]naphthalene-1-sulfonic acid at the C-terminus served as the analyte. By means of CZE using 2 mol/L acetic acid as electrolyte and UV detection at 214 nm, the non-phospho ...

However, older occupations are located at the entrance and the collapsed zone of this vast karst network. Unfortunately, companies looking for phosphate had earlier truncated this original filling and only nine Paleolithic stratigraphic outliers (T1 to T9) remained ...

- Abstract:
- ... In remote sensing, it is commonly accepted that land remote-sensing satellite (LANDSAT) top-of-atmosphere (TOA) reflectance is less accurate than atmospheric correction (AC) reflectance, as the former is not calibrated for possible modifications in the electromagnetic radiation signals due to atmospheric scattering and absorption. This article investigates whether LANDSAT data calibrated for TOA r ...

The SAR data has been preprocessed first, which included radiometric calibration, geocoding, and speckle filtering. The HH/HV band ratio has been used to create the third band, and thus a synthetic RGB SAR image was created. The Landsat-8 data was also prepro ...

High-spatial and -radiometric resolution (H-res) thermal infrared (TIR) airborne imagery, such as the TABI-1800 (Thermal Airborne Broadband Imager) provide unique surface temperature information that can be used for urban heat loss mapping, heat island analysis, and landcover classifications. For mapping large urban areas at a high-spatial resolution (i.e., sub-meter), airborne thermal imagery nee ...

The DisTrad (Disaggregation Procedure for Radiometric Surface Temperature) model shows limited applicability for sub-pixel mapping of thermal remote-sensing images in densely vegetated areas due to the phenomenon of normalized difference vegetation index (NDVI) saturation. In this article, we compared the effect of NDVI and enhanced vegetation index (EVI) in the DisTrad model for thermal sub-pixel ...

- Abstract:

Abrupt change detection analysis using remote-sensing techniques requires radiometric congruity and atmospheric correction to monitor terrestrial surfaces over time. Two atmospheric correction methods were used ...
