Trends in Playa Inundation and Water Storage in the Ogallala Aquifer on the Texas High Plains

open access: yesHydrology, 2016
The Ogallala Aquifer is an important source of irrigation water on the Texas High plains; however, significant decreases in saturated thickness threaten its future use for irrigation. A better understanding of the roles of playas, ephemeral surface ponds,

Associations of wearable photobiomodulation device use with mitochondrial bioenergetics and fatigue in athletes and individuals with chronic fatigue

open access: yesFrontiers in Sports and Active Living
This 30-day observational pilot study evaluated associations between wearable photobiomodulation use and changes in mitochondrial bioenergetics and perceived fatigue in two physiologically distinct cohorts: athletes (n = 10) and individuals with chronic ...

Modeling of Recharge Spatial Distribution in Karst Aquifers of Tangekhosh Watershed (Bushehr Province) Using the KARSTLOP Method [PDF]

open access: yesپژوهش‌های آبخیزداری, 2020
Assessing the spatial distribution of recharge in karstified terrains is very important for water management and protection, but it is a complex issue due to the complexity of natural conditions and water movement in karst areas, and the application of ...

Modelling groundwater recharge and discharge in Hetao irrigation district using water balance model

open access: yesGuan'gai paishui xuebao
【Background and Objective】 Irrigation in the Hetao irrigation district relies on water diversion from the Yellow River. However, its flat terrain coupled with suboptimal irrigation and drainage practices over the past decades has resulted in groundwater ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

A comprehensive discrimination method for the genetic type of groundwater regime of phreatic water: a case study in the Songhua River basin of the Sanjiang Plain

open access: yesShui kexue jinzhan, 2022
Traditional methods for discriminating the genetic type of groundwater regime have some problems, such as being substantially affected by human subjective factors and the ease of producing multiple solutions.

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

open access: yesAdvanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings
