Cardiorespiratory demands of firearms training instruction and 15m shuttle tests in British law enforcement.

Objectives: Law enforcement agencies require minimum fitness standards to safeguard their officers and training staff. Firearms instructors (FI) are expected to maintain the same standards as their operational counterparts. This study aimed to quantify the daily physiological demands placed on FI.

An improved endwall-injection technique for examining high-temperature ignition of lubricating oils in shock tubes.

Ignition of the lubricating fluid in a mechanical system is a highly undesirable and unsafe condition that can arise from the elevated temperatures and pressures to which the lubricant is subjected. It is therefore important to understand the fundamental chemistry behind its ignition to predict and prevent this condition. Lubricating oils, particularly those with a mineral oil base, are very complex mixtures of thousands of hydrocarbons.

Preparing Australian diabetes educators for practice: workforce perceptions of the credentialling pathway.

The Australian Credentialled Diabetes Educator (CDE) registered trademark signifies quality care and education to those with diabetes. A review of the Australian Diabetes Educators Association (ADEA) CDE pathway was undertaken to ensure the quality of the CDE credential. The purpose of this study was to examine perceptions of the diabetes education workforce on the current pathway for educating and qualifying CDEs for practice.

FISH-Flow Cytometry Reveals Microbiome-Wide Changes in Post-Translational Modification and Altered Microbial Abundance Among Children with Inflammatory Bowel Disease.

Metaproteomic analysis of microbiome post-translation modifications (PTMm) is challenging, and little is known about the effects of inflammation on the bacterial PTM landscape in IBD. Here, we adapted and optimised fluorescence in situ hybridisation-flow cytometry (FISH-FC) to study microbiome-wide tyrosine phosphorylation (p-Tyr) in children with and without inflammatory bowel disease (IBD). Microbial p-Tyr signal was significantly higher in children with IBD, compared to those without.

The theory of Barlow packings: Basic properties and cohesive energies from exact lattice summations within the sticky hard-sphere model.

The theory of periodic Barlow multi-lattices (X1X2…XN)∞ with Xi ∈ {A, B, C} and Xi ≠ Xi+1 of stacked two-dimensional hexagonal close-packed layers is presented and used to derive exact lattice sum expressions in terms of fast converging Bessel function expansions for inverse power potentials. We describe in detail the mathematical properties of Barlow sphere packings and demonstrate that only two basic lattice sums are required to describe all periodic packings. For the sticky hard-sphere model with an attractive inverse power law potential, we find a linear correlation between the cohesive energies of different Barlow packings and the face-centered cubic packing fraction.
