Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Towards Transformative Climate Governance: Capacities and Constraints for Local Government in Aotearoa New Zealand

Environmental Policy and Governance, EarlyView.
ABSTRACT An emerging consensus calls for transformative climate governance. However, what instigates and sustains transformative pathways remains unclear. This study characterises the existence, quality and structural underpinnings of transformative governance capacities in local government climate change response in Aotearoa New Zealand, applying a ...

Policy Networks and Policy Entrepreneurship in the EU: Explaining Structural Policy Change in Pharmaceutical Innovation Incentives and Health Technology Assessment

European Policy Analysis, EarlyView.
ABSTRACT Policy process research has excelled in explaining structural policy change within national settings, but extensions and applications to the EU level have long proven challenging for scholars. Given that the EU is currently experiencing its longest period of Treaty stability since the 1980s—having evolved into a sui generis political system ...

The EU's Strategy for Sustainability: A Landmark Turn With the European Green Deal?

European Policy Analysis, EarlyView.
ABSTRACT While the European Green Deal (EGD) has been widely recognized as a milestone in the EU's sustainability strategy, scholars disagree on the nature of the policy change it represents. Critics highlight its limited social and environmental ambitions, despite its portrayal as a “man on the moon” moment.

Experimental determination of the initial compressive strength of concrete using a rebound test hammer

IOP Conference Series: Materials Science and Engineering, 2018
This paper deals with rebound hammer testing of concrete in the early stage of ageing. Six types of concrete were produced for the purpose of the presented experiment and differed in the water/cement ratio and were otherwise identical as to the input components.

A Review of Overcurrent Protection in Smart Grids Under Cyber‐Physical Threats With a Cyber‐Physical Evaluation Framework

Energy Science &Engineering, EarlyView.
By manipulating current and voltage measurements, an assailant can induce unwanted relay action while attempting to avoid detection. Detecting advanced cyber intrusions in power protection environments requires specialised data analysis and anomaly detection methods.

Experimental study on the mechanical and acoustic emission features of frozen single fractured sandstone under drop hammer impact

Gong-kuang zidonghua
Mining rock masses in high-altitude cold regions can experience instability due to low temperature environments and dynamic load disturbances. Existing research mostly focuses on the static features of fractured sandstone under different freezing ...

Uniaxial Compressive Strength of Antarctic Peninsula Rocks: Schmidt Hammer Rebound Test

Sains Malaysiana, 2017
The uniaxial compressive strength test is a destructive and time consuming test. A number of non-destructive methods using portable testing equipment are more applicable and easier to conduct. This paper presents the results of a systematic approach to determine the uniaxial compressive strength of rock material using the Schmidt hammer rebound test. A

Nutritional, Functional, and Anti‐Hypercholesterolemic Properties of Sourdough Breads From Unripe Plantain, Tiger Nut, and Fenugreek Flours

Food Chemistry International, EarlyView.
Composite sourdough breads were developed from blends of unripe plantain, tiger nut, and fenugreek flours. Optimized formulations improved pasting stability and enhanced texture, producing softer more elastic crumbs. The enriched breads contained higher dietary fiber and bioactive compounds, and significantly reduced serum cholesterol markers ...
