Quantifying colors at micrometer scale by colorimetric microscopy (C-Microscopy) approach [PDF]
Micron, Volume 176, 103557 (2024), 2023 The color is the primal property of the objects around us and is direct manifestation of light-matter interactions. The color information is used in many different fields of science, technology and industry to investigate material properties or for identification of concentrations of substances.

Prediction of uniaxial compressive strength of rock based on lithology using stacking models
Rock Mechanics Bulletin, 2023 Uniaxial compressive strength (UCS) of rock is an essential parameter in geotechnical engineering. Point load strength (PLS), P-wave velocity, and Schmidt hammer rebound number (SH) are more easily obtained than UCS and are extensively applied for the ...

Boreas, Volume 52, Issue 1, Page 42-59, January 2023., 2023 Palynological and sedimentological analyses were performed on the sediment core HH16‐1205‐GC retrieved from the central Isfjorden, West Spitsbergen. The sequence, which spans the last 7000 years, revealed an overall cooling trend with an important climate shift between 4.4 and 3.8 cal. ka BP, in addition to millennial‐scale oscillations.

Integration of natural data within a numerical model of ablative subduction: A possible interpretation for the Alpine dynamics of the Austroalpine crust [PDF]
Journal of Metamorphic Geology, 2012, 2012 A numerical modelling approach is used to validate the physical and ge- ological reliability of the ablative subduction mechanism during Alpine con- vergence in order to interpret the tectonic and metamorphic evolution of an inner portion of the Alpine belt: the Austroalpine Domain.

Integrative biology of injury in animals
Biological Reviews, Volume 98, Issue 1, Page 34-62, February 2023., 2023 ABSTRACT Mechanical injury is a prevalent challenge in the lives of animals with myriad potential consequences for organisms, including reduced fitness and death. Research on animal injury has focused on many aspects, including the frequency and severity of wounding in wild populations, the short‐ and long‐term consequences of injury at different ...

Effects of water temperature on freshwater macroinvertebrates: a systematic review
Biological Reviews, Volume 98, Issue 1, Page 191-221, February 2023., 2023 ABSTRACT Water temperature is one of the main abiotic factors affecting the structure and functioning of aquatic ecosystems and its alteration can have important effects on biological communities. Macroinvertebrates are excellent bio‐indicators and have been used for decades to assess the status of aquatic ecosystems as a result of environmental ...

Cooling history of the eastern Svecokarelides: whole-rock and mica Rb-Sr and hornblende K-Ar ages in the areas of Pihtipudas-Iisalmi and Joroinen-Sulkava, Finland [PDF]
Bulletin of the Geological Society of Finland, 1990 Rb-Sr age determination on mica and whole-rock samples and K-Ar age determination on hornblendes were carried out to get information on the time of metamorphism and early cooling in two Proterozic areas of the Finnish Svecokarelides.
