Arctic stratospheric dehydration – Part 2: Microphysical modeling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Large areas of synoptic-scale ice PSCs (polar stratospheric clouds) distinguished the Arctic winter 2009/2010 from other years and revealed unprecedented evidence of water redistribution in the stratosphere.

Frontiers of (Pareto) Optimal and Sustainable Water Management for Hydropower and Ecology

open access: yesFrontiers in Environmental Science, 2021
River regulation alters the natural flow regime of streams with consequent impacts on terrestrial and aquatic habitats of the riparian zone. The severity of such impacts can be modulated by changing the redistribution rules at water intakes and ...

Introducing NMR strategies to define water molecules that drive metal binding in a transcriptional regulator

open access: yesJournal of Magnetic Resonance Open, 2023
Staphylococcus aureus CzrA is a paradigmatic member of the ArsR family of transcriptional metalloregulators, which are critical for the bacterial response to stress.

Evidence of nitric acid uptake in warm cirrus anvil clouds during the NASA TC4 campaign [PDF]

open access: yes, 2010
Uptake of HNO3 onto cirrus ice may play an important role in tropospheric NOx cycling. Discrepancies between modeled and in situ measurements of gas-phase HNO3 in the troposphere suggest that redistribution and removal mechanisms by cirrus ice have been ...

Water redistribution and the life cycle of sahelian rodents

open access: yesMammalia, 1996
Au Burkina Faso (Oursi), outre une phase de repos sexuel induite par des facteurs non-trophiques (photoperiode et temperature) chez Arvicanthis niloticus, le metabolisme hydrique est constamment eleve, la reproduction permanente et les individus sedentaires chez les A. niloticus et Mastomys huberti qui ont une alimentation riche tout au long de l'annee

Effect of Foot Orthoses on Midfoot Pain and the Volume of Bone Marrow Lesions in the Midfoot: A Randomized Mechanism of Action Study

open access: yesArthritis Care &Research, EarlyView.
Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Impacts on the deep-sea ecosystem by a severe coastal storm [PDF]

open access: yes, 2012
Major coastal storms, associated with strong winds, high waves and intensified currents, and occasionally with heavy rains and flash floods, are mostly known because of the serious damage they can cause along the shoreline and the threats they pose to ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Water conservation in Artemisia tridentata through redistribution of precipitation

open access: yesOecologia, 2003
Water conservation is important for plants that maintain physiologically active foliage during prolonged periods of drought. A variety of mechanisms for water conservation exist including stomatal regulation, foliage loss, above- and below-ground allocation patterns, size of xylem vessels and leaf pubescence. Using the results of a field and simulation
