Comparative Numerical Studies for the Flow Energy Dissipation Features in a Vertical Two‐Stage Centrifugal Pump in Pump and Turbine Conditions

open access: yesEnergy Science &Engineering, Volume 14, Issue 2, Page 764-779, February 2026.
Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

The Shroud of Turin: An Overview of the Archaeological Scientific Studies

open access: yesTextiles
The Shroud of Turin attracts consistently the interest of both the scientific community and the general public, as many believe that it is the burial cloth of Christ. This article aims to provide a comprehensive review of the relevant scientific research

Mapping the Mistreatment Landscape: An Integrative Review and Reconciliation of Workplace Mistreatment Constructs

open access: yesJournal of Organizational Behavior, Volume 47, Issue 2, Page 237-260, February 2026.
ABSTRACT As the literature on workplace mistreatment has grown, so too have the number of constructs proposed to represent distinctive forms of mistreatment. However, considerable disagreement exists surrounding whether these proposed constructs represent unique manifestations of workplace mistreatment or represent a single underlying phenomenon.

Culture, Community, and Development: Unpacking the ‘Socio‐Cultural Milieu Dynamics’ of Solomon Islands and Their Influence on Australia's Aid Localisation

open access: yesPublic Administration and Development, Volume 46, Issue 1, Page 77-92, February 2026.
ABSTRACT Using public ethnography anchored in the post‐development theory and interpretivist epistemological paradigm, this study examines what we term the ‘socio‐cultural milieus dynamics’ (SCMD) of the Solomon Islands (SI) and how these shape meaning, discourse, and practice in ways that influence Australia's aid localisation efforts and aid outcomes.

Aerodynamic effect of a honeycomb rotor tip shroud on a 50.8-centimeter-tip-diameter core turbine [PDF]

open access: yes
A 50.8-cm-tip-diameter turbine equipped with a rotor tip shroud of hexagonal cell (or honeycomb) cross section has been tested in warm air (416 K) for a range of shroud coolant to primary flow rates.

Haptic Experiences Shift Students' Representational Gestures and Knowledge Resources

open access: yesJournal of Research in Science Teaching, Volume 63, Issue 2, Page 138-160, February 2026.
ABSTRACT The present investigation adopts an embodied cognition perspective to characterize students' learning interactions between gesture and haptic experience. Haptic technologies have emerged as a promising approach to science learning because they can simulate physical forces that students would otherwise not experience. Student‐generated gestures

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

A new approach for performing contamination control bakeouts in JPL thermal vacuum test chambers [PDF]

open access: yes
Contamination control requirements for the Wide Field/Planetary Camera II (WF/PC II) are necessarily stringent to protect against post-launch contamination of the sensitive optical surfaces, particularly the cold charge coupled device (CCD) imaging ...
