Article Abstract
Worldwide, water resources are increasingly under pressure. The Water accounting approach of the System of Environmental-Economic Accounting (SEEA) has been developed to inform decision-makers on water supply, use, and quality. However, a critical issue in water accounting is finding data and models to populate SEEA water accounts. In particular, there are challenges in aligning hydrological models with accounting principles. Also, there is a need to test further how the SEEA water accounts can be connected to policy uses. The objective of this study is to develop water accounts with the use of a hydrological model. Specifically, we apply the SWAT hydrological model in the Buyuk Menderes Basin in Turkey to estimate the key hydrological parameters required for water accounting. To adapt and link SWAT to SEEA water accounts, we develop supply and use tables and asset accounts following the SEEA water for the year 2014 and explore how water accounts can inform policymaking. This article provides new insights into the added value of using a hydrological model in constructing water accounts for better water resources management.

Sub-diurnal asymmetric warming has amplified atmospheric dryness since the 1980s.

Rising atmospheric vapor pressure deficit (VPD)-a measure of atmospheric dryness, defined as the difference between saturated vapor pressure (SVP) and actual vapor pressure (AVP)-has been linked to increasing daily mean near-surface air temperatures since the 1980s. However, it remains unclear whether the faster increases in daily maximum temperature (T) relative to daily minimum temperature (T) have contributed to rising VPD. Here, we show that the faster rise in T compared with T over land has intensified VPD from 1980 to 2023.

Introduction: Benchtop and animal models have traditionally been used to study the propagation of Onyx Liquid Embolic Systems (Onyx) used in the treatment of brain arteriovenous malformations (AVM). However, such models are costly, do not provide sufficient detail to elucidate how variations in Onyx viscosity alter flow dynamics, and rely on some trial-and-error, resulting in elongated timelines for product development.
Objectives: The goal of this study was to leverage Computational Fluid Dynamics (CFD) simulations to predict the behavior of different Onyx formulations.

Despite global phase-out initiatives, legacy polychlorinated biphenyls (PCBs) remobilize in marine ecosystems as secondary emission sources, posing ecotoxicological and human health risks emerge through cross-trophic dietary exposure pathways. This study aimed to systematically examined the distribution, trophic transfer properties, and health risks of PCBs in six fish and eight invertebrate species from the Beibu Gulf in southern China, by stable isotope analysis, hierarchical cluster analysis, and Monte Carlo simulation. The ΣPCBs concentrations ranged from 0.

In this study, we seek to deepen the understanding of the Fe effect in Ni-oxyhydroxide-mediated oxygen evolution reaction (OER) electrocatalysis in alkaline conditions, where extremely small amounts of Fe can have a dramatic impact on catalytic performance. For this purpose, Density Functional Theory (DFT) electronic structure calculations with implicit solvation description is employed in a constant pH/potential simulation framework. Nanoparticle models are considered for the nickel-based oxyhydroxide material with different degrees of Fe incorporation, and the pH/U-dependent interface structure is studied.

We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.
