EFD-C(13)03/11 Contrasting H-mode Behaviour with Fuelling and Nitrogen Seeding in the All-Carbon and Metallic Versions of JET [PDF]

open access: yes, 2013
An all-metal ITER-Like Wall (JET-ILW), consisting of beryllium in the main chamber and tungsten surfaces in the divertor, has now been installed in JET to pursue low retention of fuel species and to explore the impact on next-step-relevant plasmas.

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Beyond ENSO: Temperature, Rainfall Variability and Emerging Climate Risks in Belize

open access: yesInternational Journal of Climatology, EarlyView.
This study analyses 50 years (1975–2024) of Belize's climate data to evaluate ENSO's influence. Results show negligible ENSO impact on rainfall but a moderate signal in nighttime dry‐season temperatures, with El Niño years 0.5°C–1.0°C warmer than La Niña years.

Visualization of submerged cavitating jet. Part two : influences of hydrodynamic conditions, nozzle geometry and visualization system arrangement [PDF]

open access: yes, 2007
In visualization results of highly-submerged cavitating water jet obtained by a digital camera, the influence of parameters such as: injection pressure, nozzle diameter and geometry, nozzle mounting (for convergent / divergent flow), cavitation number ...

Impact of abrasive versus non‐abrasive cleaning on peri‐implantitis titanium release: A randomized clinical trial

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Surface decontamination is integral to peri‐implantitis treatment. However, abrasive mechanical methods can cause implant surface degradation with possible adverse biological effects. No human studies have examined whether these treatments cause titanium release or impair regenerative outcomes.
