Global gross primary productivity and water use efficiency changes under drought stress
Environmental Research Letters, 2017 Drought can affect the structure, composition and function of terrestrial ecosystems, yet drought impacts and post-drought recovery potentials of different land cover types have not been extensively studied at a global scale. We evaluated drought impacts

Environmental controls on the light use efficiency of terrestrial gross primary production
Global Change Biology, 2022 Gross primary production (GPP) by terrestrial ecosystems is a key quantity in the global carbon cycle. The instantaneous controls of leaf‐level photosynthesis are well established, but there is still no consensus on the mechanisms by which canopy‐level ...

Laboratory-Based Factors Predicting Skiing Performance in Female and Male Biathletes
Frontiers in Sports and Active Living, 2020 Skiing in biathlon is a high-intensity, intermittent endurance discipline. This study aimed to evaluate the relationships between laboratory-derived physiological variables and skiing performance during a field-based biathlon competition (BC) for female ...

The efficient operation of the surgical pathology gross room [PDF]
Biotechnic & Histochemistry, 2008 The gross room is the area where pathology specimens from operating rooms are transferred for pathology review and analysis, serving as the bridge between the treating physician and diagnostic surgical pathologist. Reaching the correct diagnosis for a specimen depends on the proper handling and processing of tissue transferred to this very busy area ...
