Characteristics of water absorption capacity of weathered sandstone based on nuclear magnetic resonance and wave velocity testing

open access: yesShuiwen dizhi gongcheng dizhi
Water is a key factor in the weathering and erosion of rocks, and highly porous rocks are generally more susceptible to weathering. However, there has been a lack of in-situ methods for assessing the water absorption capacity of rocks. To investigate the

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Effects of Potassium Supply in Nutrient Solution on Water and Nutrient Absorption of Substrate-Grown Tomato Plants

open access: yesHorticulturae
Potassium (K+) functions as a critical “regulator” and “quality element” in plants, with its physiological roles varying across developmental stages. To clarify the effects of different K+ amounts in nutrient solution on water and nutrient absorption ...

Study on Reliability of Water Absorption Diagnosis through Precise Water Absorption Test

open access: yesJournal of Electrical Engineering and Technology, 2012
Accidents caused by water absorption in water-cooled generator stator windings often occur all over the world. The absorption into the insulator of the coolant, which is used to cool down the heat generated by stator windings during operation, leads to the deterioration of dielectric strength, and insulation breakdown. An insulation breakdown may cause

BMI‐1 modulation and trafficking during M phase in diffuse intrinsic pontine glioma

open access: yesFEBS Open Bio, EarlyView.
The schematic illustrates BMI‐1 phosphorylation during M phase, which triggers its translocation from the nucleus to the cytoplasm. In cycling cells, BMI‐1 functions within the PRC1 complex to mediate H2A K119 monoubiquitination. Following PTC596‐induced M phase arrest, phosphorylated BMI‐1 dissociates from PRC1 and is exported to the cytoplasm via its

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

open access: yesFEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

Alteration of Water Absorption Coefficient of Spruce (Picea abies (L.) Karst.) due to Thermal Modification

open access: yesDrvna Industrija, 2011
The aim of the investigations was to evaluate the infl uence of a thermal modifi cation on the water absorption behaviour of spruce (Picea abies(L.) Karst.).

Epithelial water absorption: Osmosis or cotransport? [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
A paradigm lost? Not according to the studies of Duquette, Bissonnette, and Lapointe (1), which present a direct test of the recently advanced cotransport hypothesis of water absorption. The results of these studies argue, strongly, that the widely accepted notion that osmotic coupling is the single mechanism responsible for water transport across ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Performance Analysis of a GAX Absorption Cycle with Ionic Liquid-water Working Pairs

open access: yesZhileng xuebao, 2019
Heat-driven absorption refrigeration technology is an important approach for solar-energy utilization and industrial-waste heat recovery. Among them, the generation and absorption heat exchange (GAX) absorption cycle exhibits a high efficiency whose ...
