Driving continuous improvement of sustainability certification for industrial biobased systems through comprehensive sustainability requirements

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Existing monitoring frameworks for sustainability certification schemes and labels (CSLs) have largely prioritised environmental aspects, while the social and economic pillars of sustainability remain comparatively underdeveloped. Also, dedicated circularity requirements tailored to biobased systems are still largely lacking, despite being ...

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Experimental Investigation on Hydraulic Characteristics of the Flow in the Pre-aerator Stepped Spillways

工程科学与技术, 2008
:The hydraulic characteristics of the smooth spillway, the stepped spillway and the pre aerator stepped spillway have been studied respectively. By now the stepped spillway hasn't been applied successfully in instance project when the water head is very ...

Beyond salaries: Teachers' experiences of navigating early years education amid economic instability in Türkiye

British Educational Research Journal, EarlyView.
Abstract The intersection of economic conditions and early years education has long been debated, particularly where financial constraints shape educational practice and professional realities. Türkiye, characterised by high inflation and structural vulnerabilities in purchasing power parity, provides a critical context for examining how economic ...

The Study of Energy Loss in Stepped- Labyrinth Spillways

علوم آب و خاک, 2020
A ‘spillway’ is a structure used to provide the controlled release of flood water from upstream into downstream area of a dam. As an important component of every dam, a spillway should be constructed strongly, reliably and efficiently to be used at any ...

Analysis of the longitudinal distribution of pressures near the ends of the vertical and horizontal faces in stepped spillway of slope 1V: 0.75H

RBRH, 2018
Stepped spillways have been widely used for flood runoff due to of their constructive advantages and in regards to energy dissipation during the drop, allowing downstream dissipation structures to be designed in smaller dimensions.

Hydraulic design of stepped spillways

, 2002
Roller Compacted Concrete (RCC) is becoming an increasingly popular method of constructing and protecting dam embankments. RCC naturally lends itself to a stepped configuration by the construction technique of roller compacting successive horizontal concrete lifts. To date, there have been numerous RCC stepped spillways constructed worldwide, yet there

Single‐subject designs in character education: Methods for rigorous, contextual, and practitioner‐led research

British Educational Research Journal, EarlyView.
Abstract Character education research is often constrained by blunt methodological tools. Surveys capture breadth without depth; case studies offer richness but lack replicability; and randomised controlled trials (RCTs), though indispensable at the policy level, are costly, disruptive and ill‐suited to everyday practice with individual pupils.
