Potential of nitrogen-fixing symbiotic systems for revegetation strategies of calcareous quarries in Mediterranean conditions [PDF]

, 2006
Anthropogenic degradation activities (overgrazing, deforestation, quarry exploitation¿) together with a long dry and hot summer, with scarce, erratic but torrential rainfalls, is a major threat to Mediterranean ecosystem sustainability.

Astragalus ecomorphology in Quaternary elephantids

Journal of Quaternary Science, EarlyView.
ABSTRACT The astragalus plays a fundamental role in the graviportal locomotion of proboscideans, reflecting the biomechanical constraints imposed by large body masses. This study analyses the morphological variability of the astragalus in Quaternary elephantids using linear biometry and 3D geometric morphometrics, incorporating an unpublished ...

Kinematic alignment, but not mechanical alignment, preserves the knee–ankle relationship after total knee arthroplasty: A retrospective radiographic analysis from the FP‐UCBM Knee Study Group

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose Several alignment strategies have been proposed in total knee arthroplasty (TKA), with the two extremes being mechanical alignment (MA) and unrestricted kinematic alignment (KA). While MA standardises coronal knee parameters to achieve a neutral alignment, KA reproduces each patient's native joint lines.
