Influence of Past Climate Changes on the Current Distribution of a Rare and Endemic Species: Anatolian Spiny Mouse

open access: yesHittite Journal of Science and Engineering, 2023
This research focuses on species distribution modelling (SDM) to have an idea of distribution of Anatolian spiny mouse, Acomys cilicicus in the Last Glacial Maximum (LGM), the mid-Holocene and present by using coordinates along Silifke which is the only ...

A model for the formation of the Pradol (Pradolino) dry valley in W Slovenia and NE Italy

open access: yesGeologija, 2021
In tectonically active mountain ranges, the landscape is shaped by the interplay of erosion/sedimentation and tectonically driven crustal deformation. Characteristic landforms such as moraines, wind gaps, fault scarps, and river terraces can be used to

The Alpine LGM in the boreal ice-sheets game [PDF]

open access: yesScientific Reports, 2017
AbstractNew chronologic and stratigraphic constraints from the Garda morainic amphitheater define the extension of the last glaciation in the Adige-Sarca system and improve the Alpine LGM dataset. Together with the available chronology of the Rhine and Tagliamento systems, our results indicate a synchronous maximum culmination of Alpine glaciers during

Effect of hygrothermal aging on the tribological behavior of HDPE composites for bio-implant application

open access: yesPolymer Testing, 2021
High density polyethylene (HDPE) is a material which was known for its biocompatibility and its application for artificial joints. However, the wear resistance of a HDPE can be enhanced with addition of reinforcements.

Late quaternary glacial history of the La Ji Shan: Implications for the LGM on the northeastern Tibetan Plateau

open access: yesFrontiers in Earth Science, 2023
Previous studies have suggested that the Bayan Har Shan and Lake Donggi Cona areas on the northeastern Tibetan Plateau were not glaciated during the Last Glacial Maximum (LGM; MIS2).

Comparative study of fatigue assessment of defective material based on affected depth

open access: yesComptes Rendus. Mécanique, 2022
In this work, we propose a comparative study of fatigue assessment of artificial surface defects based on affected depth (AD). The defect is assumed to be a void (semi-spherical, elliptical, or circumferential notches) on the surface of a material ...
