Kinematics and physical conditions of HI in nearby radio sources. The last survey of the old Westerbork Synthesis Radio Telescope [PDF]

open access: yes, 2017
We present an analysis of the properties of neutral hydrogen (HI) in 248 nearby (0.0230$ mJy and for which optical spectroscopy is available. The observations were carried out with the Westerbork Synthesis Radio Telescope as the last large project before

Strengthening Potentials of Lithium‐Doped Soda–Lime–Silicate Glasses Through Surface Crystallization of Quartz‐ss

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.
ABSTRACT The formation of a crystallized surface layer, having a lower coefficient of thermal expansion (CTE) than the parent glass, can be exploited to place the glass surface under compression during cooling from crystallization temperature and hence improve mechanical properties.

Consistency of cosmic microwave background temperature measurements in three frequency bands in the 2500-square-degree SPT-SZ survey

open access: yes, 2019
We present an internal consistency test of South Pole Telescope (SPT) measurements of the cosmic microwave background (CMB) temperature anisotropy using three-band data from the SPT-SZ survey.

Upcycling Brewers' Spent Grain Into High‐Performance Protein Nanofibers for Sustainable Non‐Woven Textiles

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 3, March 2026.
A common brewing by‐product is transformed into fine, flexible fibers using a simple spinning process, pointing to a new route for turning waste into useful materials. The study shows how gentle post‐treatments make these fibers far more robust in everyday conditions, opening the door to sustainable fabrics and functional nonwovens.

Non-universal Critical Quantities from Variational Perturbation Theory and Their Application to the BEC Temperature Shift

open access: yes, 2004
For an O(N) symmetric scalar field theory with Euclidean action integral d^3x [1/2 |nabla phi|^2 + 1/2 r phi^2 + 1/4! u phi^4], where phi = (phi_1,...,phi_N) is a vector of N real field components, variational perturbation theory through seven loops is ...

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

open access: yes, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Evaluation of the yield stability of lentil genotypes by combining AMMI and BLUP techniques

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract This study evaluated the yield stability of 14 advanced lentil genotypes alongside two control cultivars (Kimia and Gachsaran) across three growing seasons (2013–2016) and three locations in Iran (Gachsaran, Ilam, and Khoramabad). A randomized complete block design with three replications was employed at each site.
