On the Water Retention Behaviour of Shales [PDF]

open access: yesFourth EAGE Shale Workshop, 2014
The involvement of shales in engineering fields such as the extraction of shale gas or the nuclear waste geological disposal is mainly driven by the low permeability and the high retention properties of these geomaterials. The high capillary forces developed in the matrix of the shales allow the fluid trapping with the consequence that the material ...

WATER RETENTION IN PNEUMONIA [PDF]

open access: yesArchives of Pediatrics & Adolescent Medicine, 1920
It has been the custom at the Children's Memorial Hospital to keep daily weight records of all children under 2 years of age, if not suffering with a contagious disease. Dr. Amberg called our attention to the fact that children who keep up their weight or gaining weight during a febrile disease, may begin to lose weight with the disappearance of the ...

Energy Harvesting of Ionic Polymer-Metal Composites Based on Microcellular Foamed Nafion in Aqueous Environment

open access: yesActuators, 2020
The purpose of this study was to determine how to improve the energy-harvesting properties of polymer electrolyte membranes by varying their porosity. We achieved this by applying microcellular foaming process (MCP) to Nafion-based ionic polymer–metal ...

Study on TEMPO-Mediated Oxidation of N-Succinyl Chitosan and the Water Retention Property

open access: yesMolecules, 2020
C-6 oxidized chitosan is of great interest in obtaining a new moisture retention polymer like hyaluronic acid. The direct C-6 specific oxidation of chitosan mediated by the TEMPO/NaClO/NaBr system has proven to be difficult because of the high ...

Changes in the water retention of mountainous landscapes since the 1820s in the Austrian Alps

open access: yesFrontiers in Environmental Science, 2023
Interactions of humans with the environment are strongly related to land use and land cover changes (LULCCs). In the last decades, these changes have led to a degradation of ecosystem services, including water regulation and flood control.

Selective Copolymerization from Mixed Monomers of Phthalic Anhydride, Propylene Oxide and Lactide Using Nano-Sized Zinc Glutarate

open access: yesNanomaterials
Selective polymerization with heterogeneous catalysts from mixed monomers remains a challenge in polymer synthesis. Herein, we describe that nano-sized zinc glutarate (ZnGA) can serve as a catalyst for the selective copolymerization of phthalic anhydride

Soil moisture retention on slopes under different agricultural land uses in hilly regions of Southern Transdanubia

open access: yesHungarian Geographical Bulletin, 2020
Increasingly severe weather extremes are predicted as one of the consequences of climate change. According to climatic models, weather extremities induce higher risks for both flood and drought in the Carpathian Basin.
