“Cold Tropics”: Permafrost Existence and Thickness on Eastern Nevado Coropuna (Southern Peruvian Andes) Revealed by Ground‐Penetrating Radar and Geoelectrical Soundings

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The existence of permafrost was explored at tropical latitude on Nevado Coropuna (southern Peruvian Andes) using a combination of ground‐penetrating radar (GPR) and vertical electrical sounding (VES) in order to strengthen the mutual validation of data processing and interpretation.

Simulating Arctic Greening: Microbial Responses in Thawing Yedoma Permafrost

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Arctic permafrost soils and sediments store vast amounts of organic carbon. With global warming intensifying, these soils are increasingly exposed to microbial decomposition. Further, Arctic warming and longer growing seasons drive regional greening, potentially accelerating the degradation of the previously frozen organic matter through ...

Overtopping Protection Alternatives For Dams

, 1992
A reevaluation of design floods for dam safety within the united states showed that the need to modify dams to accommodate larger floods has greatly increased in recent years. The occurrence of larger design floods would result in overtopping of the dams

x‐Ray Structure of Streptomyces avermitilis Phospholipase D Reveals a Ca2+‐Stabilized Expanded Active‐Site Cleft Adapted for Phospholipid Binding

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Phospholipase D (PLD) catalyzes the hydrolysis of phospholipids to generate phosphatidic acid and free head groups such as choline. Among bacterial PLD enzymes, Streptomyces chromofuscus PLD (SchPLD), a member of the alkaline phosphatase D (PhoD) superfamily, exhibits unique Ca2+‐dependent phospholipase activity.

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Combining LPJ-GUESS and HASM to simulate the spatial distribution of forest vegetation carbon stock in China

, 2014
It is very important in accurately estimating the forests' carbon stock and spatial distribution in the regional scale because they possess a great rate in the carbon stock of the terrestrial ecosystem.
