The effect of ancillary ligands on hydrocarbon C-H bond functionalization by uranyl photocatalysts.

The aqueous uranyl dication has long been known to facilitate the UV light-induced decomposition of aqueous VOCs (volatile organic compounds), the long-lived highly efficient, uranyl excited state. The lower-energy visible light excited uranyl ion is also able to cleave unactivated hydrocarbon C-H bonds, yet the development of this reactivity into controlled and catalytic C-H bond functionalization is still in its infancy, with almost all studies still focused on uranyl nitrate as the precatalyst. Here, hydrocarbon-soluble uranyl nitrate and chloride complexes supported by substituted phenanthroline (Phphen) ligands are compared to each other, and to the parent salts, as photocatalysts for the functionalization of cyclooctane by H atom abstraction.

The Difference between PC-Based and Immersive Virtual Reality Food Purchase Environments on Useability, Presence, and Physiological Responses.

Computer simulations used to study food purchasing behavior can be separated into low immersion virtual environments (LIVE), which use personal computers and standard monitors to display a scene, and high immersion virtual environments (HIVE) which use virtual reality technology such as head-mounted displays to display a scene. These methods may differ in their ability to create feelings of presence or cybersickness that would influence the usefulness of these approaches. In this present study, thirty-one adults experienced a virtual supermarket or fast-food restaurant using a LIVE system or a HIVE system.

The challenges of keeping clinicians unaware of their participation in a national, cluster-randomised, implementation trial.

Background: Implementation of recommendations from clinical practice guidelines is essential for evidence based clinical practice. However, the most effective methods of implementation are unclear. We conducted a national, cluster-randomised, blinded implementation trial to determine if midwife or doctor local implementation leaders are more effective in implementing a guideline for use of oral dextrose gel to treat hypoglycaemic babies on postnatal wards.

Oral dextrose gel to treat neonatal hypoglycaemia: Clinician survey.

Aims: To determine the use of oral dextrose gel to treat neonatal hypoglycaemia in New Zealand (NZ), to identify barriers and enablers to the implementation of the guideline and to determine if there is variation in management between clinical disciplines caring for at-risk babies.

Methods: An online survey was distributed to clinicians (including doctors, midwives and nurses) caring for babies with neonatal hypoglycaemia via stakeholders and maternity hospitals.

Results: A total of 251 clinicians from all 20 District Health Boards (DHBs) completed the survey.

Reducing the polyp burden in serrated polyposis by serial colonoscopy: the impact of nationally coordinated community surveillance.

Background: Serrated polyposis syndrome (SPS) is associated with an increased risk of colorectal cancer (CRC) and an evolving management approach. The aims of this study were to assess the polyp burden reduction over time, and the incidence of CRC in serrated polyposis patients undergoing community surveillance.

Methods: This is an observational study based on prospectively collected data.
