Numerical Investigations of Snowdrift Characteristics on Roofs with Consideration of Snow Crystal Morphological Features

Buildings
Under extreme snowfall conditions, wind-induced snow drifting can lead to the redistribution of snow accumulation on roofs, resulting in localized overloads that pose a serious threat to building structural safety.

Translateral and Transtibial Techniques Provide Similar Patient Outcomes in Arthroscopic Anterior Cruciate Ligament Reconstruction

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To compare the outcomes of the transtibial technique (TT) and the translateral technique (TLL) for anterior cruciate ligament (ACL) reconstruction in an Asian population. Methods Patients who underwent either TT or TLL for ACL reconstruction between 2019 and 2021 were identified.

A Modified Anatomical All‐Inside Double‐Bundle Anterior Cruciate Ligament Reconstruction Technique

Arthroscopy Techniques, EarlyView.
Abstract Arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) is the standard surgical treatment for ACL injuries and is most commonly performed using anatomical single‐bundle (SB) or double‐bundle (DB) techniques. With the development of the all‐inside technique, the all‐inside SB technique using socket‐based tunnels and cortical ...

Impact of loose-laid gravel on the pressure distribution over a flat roof

Advances in Wind Engineering
A series of large-scale wind tunnel tests were conducted to quantify the impact of loose-laid gravel on the pressure distribution over a flat roof. Measurements were presented for the pressure distribution over the surface of a flat roof on a square plan

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.

Benefits of green roof installations on buildings with flat roof

, 2022
In this paper, different aspects of a green roof installation are analyzed on several typical buildings in Belgrade. The analysis is performed for buildings with extensive and intensive green roofs. The goal was to determine their influence on existing buildings' structural capacity and thermal characteristics.

‘When joy comes your way, you have to grab it!’ Troubling how queer joy features in the lives of LGBT+ school‐attending youth in South Africa

British Educational Research Journal, EarlyView.
Abstract Recently, the concept ‘queer joy’ has gained interest in LGBT+ scholarship in the West. I use this scholarship as an entry point to explore how school‐attending LGBT+ youth express joy and how joy serves as a form of resistance against gender and sexuality norms in educational settings.

Study on the snow drifting modelling criteria in boundary layer wind tunnels [PDF]

Constructii: Journal of Civil Engineering Research, 2014
The paper presents a study on modelling the wind drifting of the snow deposited on the flat roofs of buildings in wind tunnel. The physical model of snow drifting in wind tunnel simulating the urban exposure to wind action is not frequently reported in ...

IMACulate(DE3), an E. coli Strain for High Purity His‐Tagged Protein Purifications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Immobilised Metal Affinity Chromatography (IMAC) is widely used to purify his‐tagged recombinant proteins from Escherichia coli. However, endogenous contaminants with histidine clusters, such as GFAT and PDH E1 proteins, are often co‐purified with the target protein.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
