Never Mind the Bollards: Exploring the Role of GCHQ, MI5, and the National Technical Authorities in UK Security Markets

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT The cultures and governance of security markets in the United Kingdom are often characterised through a paradoxical narrative of simultaneous state retreat and progressive advance. In the face of repeated recent high‐profile security failures, and global changes in material political economy, we argue that UK security governance is adapting to

Experimental Testing and Strut-and-Tie Modeling of Full-Scale Precast Concrete Girders with FRP Repaired End Regions

Applied Sciences, 2020
Bridges located in cold regions are susceptible to extreme deterioration due to harsh climate conditions. Distressing of girder’s end regions is among the most common damage types in these bridges.

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

Journal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Improvement and Application of the Softened Strut-and-Tie Model

IOP Conference Series: Materials Science and Engineering, 2017
Previous experimental researches indicate that reinforced concrete beam-column joints play an important role in the mechanical properties of moment resisting frame structures, so as to require proper design. The aims of this paper are to predict the joint carrying capacity and cracks development theoretically.

The impact of footwear on human talar trabecular architecture

Journal of Anatomy, EarlyView.
Medial and lateral views of the human foot skeleton in the shod and unshod groups, with color maps representing mean relative trabecular bone volume fraction (rBV/TV) in the talus for each group. The shod group exhibited greater rBV/TV in the medial and posterior talus, whereas the unshod group had greater rBV/TV in the talar head and neck.

Numerical analysis of reinforced concrete dapped-end beams [PDF]

Revista IBRACON de Estruturas e Materiais
The reinforced concrete dapped-ends present in beams, being regions of discontinuity, require non-trivial models for their analysis and design, such as the strut-and-tie model, the shear-friction model, and the finite element method.

Direct Inelastic Strut-Tie Model Using Secant Stiffness

, 2005
A new strut-tie model using secant stiffness, Direct Inelastic Strut-Tie Model, was developed. Since basically the proposed design method uses linear analysis, it is convenient and stable in numerical analysis.

10th East Asia-Pacific Conference on Structural Engineering and Construction: Materials, Experimentation, Maintenance and Rehabilitation (EASEC-10) [PDF]

, 2006
This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced ...

Listener Commentary Reveals the Social Salience of Accent Features

Journal of Sociolinguistics, EarlyView.
ABSTRACT This paper examines how listeners from two regions of England perceive and describe Northern English accents. Using the Salient Language in Context (SLIC) methodology, 94 respondents from two regions of England listened to recorded voices, clicking when they noticed features and providing open‐ended comments.

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles

Revista IBRACON de Estruturas e Materiais, 2020
: Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress
