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

open access: yesThe 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

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

open access: yesJournal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Mitochondrial respiratory capacities are not linked to individual variation in hypoxia tolerance and standard metabolic rate in European seabass Dicentrarchus labrax

open access: yesJournal of Fish Biology, EarlyView.
Abstract In hypoxic environments, fish attempt to regulate their metabolic rate as oxygen levels in the water decline. Individuals that have low energy requirements for maintenance – standard metabolic rate (SMR) – are expected to have higher hypoxia tolerance, measured as the critical water oxygen saturation threshold (Scrit) below which they cannot ...

Tracking hatchery and wild Atlantic salmon (Salmo salar) smolt during river exit and early marine migration to assess survival, predation risk and migration speed

open access: yesJournal of Fish Biology, EarlyView.
Abstract Significant declines in Atlantic salmon (Salmo salar) populations across their range have prompted an increased use of hatchery supplementation programmes to support population recovery. However, concerns persist regarding the effectiveness of these programmes due to limited understanding of how hatchery‐reared salmon perform post‐release in ...

MEMBANGUN DESA MANDIRI UDANG VANAME: PENDAMPINGAN MAHASISWA DALAM MENINGKATKAN KUALITAS AIR KOLAM BUNDAR UDANG VANAME DI DESA BUGEMAN

open access: yesAs-Sidanah
Bugeman Village has great potential for vaname shrimp farming. However, vaname shrimp production in this village is still hindered by suboptimal pond water quality. This has resulted in high shrimp mortality rates and low yields.

Simulation of turbulent combustion in a self-aerated domestic gas oven

open access: yesApplied Thermal Engineering, 2017
Abstract Characteristics of the partially-premixed flames are numerically studied in a self-aerated domestic gas oven. The fuel (methane) and air are introduced into the premixing chamber from different inlets and, therefore, the non-premixed formulation of the reactive scalars is possible to use.

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.
