Pump turbines in existing powerplants
, 2019 En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden benytter seg av eksisterende løftelinjeteori for design og optimalisering av kontraroterende propeller, men den er modifisert for ...

A Review of the Applications and Challenges of Pulsed Electric Fields in Fish Ecological Protection
Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT The use of pulsed electric fields (PEF) to regulate fish swimming patterns, especially during migratory channel restoration in dammed rivers, faces significant operational challenges. These challenges can generally be attributed to the multifaceted nature of fish behaviour and limitations in research on physical interception methods.

Energy Storage, Volume 8, Issue 4, June 2026.ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.

Redistribution of the inlet temperature profile through the SSME fuel turbine [PDF]
A three-dimensional Euler code was used to predict radial inlet temperature profile redistribution through the two-stage fuel turbopump turbine. The calculation was made at the FPL condition using a turbine inlet radial temperature profile.

Creativity and Innovation Management, Volume 35, Issue 2, Page 356-373, June 2026.ABSTRACT Sustainability transitions, such as electrifying the process industry, require a bundle of related innovations to make meaningful progress. Drawing on literature on innovation through tinkering, that is, adaptive, typically small‐scale experimentation with various forms of innovation, and applying a micropolitical perspective, this qualitative

Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study
Journal of Sleep Research, Volume 35, Issue 3, June 2026.Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.

Advanced Science, Volume 13, Issue 28, 18 May 2026.Graphene‐skinned alumina fiber (GAF) is a new composite with graphene conformally grown on individual alumina fibers via chemical vapor deposition (CVD). GAF's dynamic, continuous and scalable production is achieved by using a home‐made roll‐to‐roll (RTR) CVD system featuring integrated degumming and growth chambers. GAF possesses tunable conductivity,

Business Strategy and the Environment, Volume 35, Issue 4, Page 4912-4924, May 2026.ABSTRACT The role of business towards achieving the 17 Sustainable Development Goals (SDGs) has been well established. However, SDG contextualization continues to pose a conundrum, particularly for firms operating in multiple contexts. This becomes even more problematic in the case of SDG 11, the only goal in the sustainable development agenda directly
