Understanding the influence of Malta litho‐structural features on the dynamics of nitrate transport in the vadose zone

Vadose Zone Journal, Volume 24, Issue 6, November/December 2025.
Abstract Coastal aquifers in the Mediterranean are increasingly stressed by climate change, intensive agriculture, and rising water demand. In Malta island, where groundwater is a key resource, nitrate contamination remains a persistent issue despite regulatory efforts and the designation of the islands as a Nitrate Vulnerable Zone.

Intestinal inflammation induces glymphatic remodeling, priming early neurodegenerative signals in male mice

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION Inflammatory bowel disease triggers extraintestinal manifestations, including in the central nervous system (CNS). However, the direct impact of peripheral inflammation on the CNS is largely unknown. METHODS Using a mouse model of colitis with pain and anxiety‐like behavior, we investigated the intricate pathogenic link between ...

Deuterium ion irradiation for tritium breeding material and evaluation for tritium inventories in test blanket module and blanket of a demonstration reactor [PDF]

Journal of Nuclear Materials, 2011
Abstract The tritium produced in a tritium breeder of blanket has to be recovered under the temperature distribution to reduce the tritium inventory. Lithium titanate pebbles were irradiated by deuterium ions with different temperatures and ion fluences. The deuterium retained in the pebbles desorbed in forms of HD, D 2 , HDO and D 2 O. The amount of

Diffusing alpha‐emitters radiation therapy: In vivo measurements of effective diffusion and clearance rates across multiple tumor types

Medical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Diffusing alpha‐emitters radiation therapy (“Alpha‐DaRT”) is a new modality that uses alpha particles to treat solid tumors. Alpha‐DaRT employs interstitial sources loaded with low activities of 224Ra$^{224}{\rm Ra}$, designed to release a chain of short‐lived alpha‐emitters, which diffuse over a few millimeters around each source ...

A h‐Adaptivity Strategy for Hybridizable Discontinuous Galerkin (HDG) Simulations of Fluid Transport Models in Tokamak Plasma

International Journal for Numerical Methods in Engineering, Volume 126, Issue 17, 15 September 2025.
ABSTRACT The highly anisotropic, multi‐scale nature of fusion plasma simulations in tokamaks, combined with the complexity in the geometries of plasma‐facing components and magnetic equilibrium, challenges numerical schemes. They therefore require the development of advanced numerical techniques to enhance computational efficiency and enable codes to ...

Modelling Electrical Conductivity Variation in the Intermittent, High‐Salinity Scotts Creek Catchment, South‐Eastern Australia Using a Travel Time Distribution Approach

Hydrological Processes, Volume 39, Issue 9, September 2025.
A travel time age‐based model successfully examined to simulate complicated behaviour of high‐frequency EC data in an Australian catchment with an intermittent flow regime for 20 years. Including high salinity data for very low flows and using two catchment state relationships (based on a discharge threshold) to modulate storage selection function ...
