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

open access: yesBritish 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.

Effects of angle of attack and vertical fin on transonic flutter characteristics of an arrow-wing configuration [PDF]

open access: yes
Experimental transonic flutter results are presented for a simplified 1/50 size, aspect ratio 1.77, wind tunnel model of an arrow wing design. Flutter results are presented for two configurations; namely, one with and one without a ventral fin mounted at

Engineering habits of mind in preschool children at Scottish forest nurseries and Australian bush kinders

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Nature‐based learning environments for early childhood are expanding, as is research into their affordances and pedagogies. Engineering in these environments is not well studied. Previous work considered engineering experiences through the lens of ‘designerly play’, finding that natural materials, the space for larger creations and ...

The effects of rotational flow, viscosity, thickness, and shape on transonic flutter dip phenomena [PDF]

open access: yes
The transonic flutter dip phenomena on thin airfoils, which are employed for propfan blades, is investigated using an integrated Euler/Navier-Stokes code and a two degrees of freedom typical section structural model. As a part of the code validation, the

The Missing Link: Connecting Cultivation Conditions and Refolding Performance via Inclusion Body Biophysical Properties

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Inclusion bodies (IBs) frequently form during the expression of heterologous proteins in Escherichia coli and are therefore important in pharmaceutical production. While it is accepted that cultivation conditions affect cultivation performance, the link to refolding performance remains unexplored. This study proposes that this interplay relies,
