The Impact of COVID-19 on Well-Being: Welsh Children's Perspectives.

The COVID-19 pandemic saw drastic and unprecedented actions by governments to mitigate the spread of the virus. Often, the restrictions limited in-person interaction and included the closure of schools. To investigate the impact of both the pandemic and resulting restrictions, the International Society of Child Indicators developed the Childrens Worlds: COVID-19 Supplement.

Drug policy goals in a changing landscape: Perspectives of practitioners in Japan.

Background: In Japan, responses to people with drug dependency problems and who frequently re-enter the criminal justice system have undergone significant change in recent years, resulting in a heavier emphasis placed on non-criminal justice interventions and greater diversification of practitioners. To better understand how different practitioners are negotiating and adapting to their changing environments, this paper examines the goals of practitioners who work with individuals who are on probation, parole or have received a suspended sentence for an illegal drug offence.

Method: Q methodology was utilised, with participation of 89 practitioners from across the fields of criminal justice, health, social welfare, and local government.

Medical student and trainee doctor views on the 'good' doctor: Deriving implications for training from a Q-methods study.

Purpose: In context of changing patient demographics, this study explores what doctors and medical students believe being a 'good' doctor means and identifies implications for training.

Method: Using Q-methodology, a purposive sample of 58 UK medical students and trainees sorted 40 responses to the prompt 'Being a "good" doctor means….' Participants explained their array choices in a post-sort questionnaire.

Physical and electrochemical area determination of electrodeposited Ni, Co, and NiCo thin films.

The surface area of electrodeposited thin films of Ni, Co, and NiCo was evaluated using electrochemical double-layer capacitance, electrochemical area measurements using the [Ru(NH[Formula: see text])[Formula: see text]][Formula: see text]/[Ru(NH[Formula: see text])[Formula: see text]][Formula: see text] redox couple, and topographic atomic force microscopy (AFM) imaging. These three methods were compared to each other for each composition separately and for the entire set of samples regardless of composition. Double-layer capacitance measurements were found to be positively correlated to the roughness factors determined by AFM topography.

Spatial and temporal features of the growth of a bacterial species colonizing the zebrafish gut.

Unlabelled: The vertebrate intestine is home to microbial ecosystems that play key roles in host development and health. Little is known about the spatial and temporal dynamics of these microbial communities, limiting our understanding of fundamental properties, such as their mechanisms of growth, propagation, and persistence. To address this, we inoculated initially germ-free zebrafish larvae with fluorescently labeled strains of an Aeromonas species, representing an abundant genus in the zebrafish gut.

Hydrogen evolution reaction measurements of dealloyed porous NiCu.

: Porous metals are of interest for their high surface area and potential for enhanced catalytic behavior. Electrodeposited NiCu thin films with a range of compositions were electrochemically dealloyed to selectively remove the Cu component. The film structure, composition, and reactivity of these samples were characterized both before and after the dealloying step using scanning electron microscopy, energy-dispersive spectroscopy, and electrochemical measurements.

An electrochemical cell for the efficient turn around of wafer working electrodes.

We present a new design for an electrochemical cell for use with wafer working electrodes. The key feature of the design is the use of half turn thumb screws to form a liquid-tight seal between an o-ring and the sample surface. The assembly or disassembly of the cell requires a half turn of each thumb screw, which facilitates the quick turn around of wafer samples.

Double-ink dip-pen nanolithography studies elucidate molecular transport.

We have investigated the transport mechanism of the inks most typically used in dip-pen nanolithography by patterning both 16-mercaptohexadecanoic acid (MHDA) and 1-octadecanethiol (ODT) on the same Au{111} substrate. Several pattern geometries were used to probe ink transport from the tip to the sample during patterning of both dots (stationary tip) and lines (moving tip). When ODT was written on top of a pre-existing MHDA structure, the ODT was observed at the outsides of the MHDA structure, and the transport rate increased.

Transport rates vary with deposition time in dip-pen nanolithography.

By patterning with dip-pen nanolithography using tip dwell times ranging from 15 s to 2 h over a period of 19 h, we show that the transport rate for smaller patterns is different than for larger ones. This transport behavior is found for both 1-octadecanethiol (ODT) and 16-mercaptohexadecanoic acid (MHDA) inks on gold substrates. Additionally, MHDA shows an overall decrease in transport rate as a function of total writing time during such experiments.

Heat-stabilized phospholipid films: film characterization and the production of protein-resistant surfaces.

Phospholipid films have been shown in a number of studies to exhibit potential as nonfouling surfaces for biomaterial applications. However, the practical application of such films has been hindered by instability in aqueous solutions and significant detachment under mild shear stresses. Methods for stabilizing lipid films have been investigated, but to date require the presence of specific functional groups or chemical modification of the lipid molecule.

Should patients with challenging anatomy be offered endovascular aneurysm repair?

Objectives: Treatment of abdominal aortic aneurysm is controversial in patients at high physiologic risk for open repair and high anatomic risk for endovascular repair. We compared outcome in patients at high risk because of anatomy (short or angulated neck), severe occlusive disease, or bilateral iliac aneurysms (group A) with outcome in patients at low risk (group B).

Material And Methods: Patients at high anatomic risk who underwent treatment between October 1998 and March 2002 with the Zenith endovascular graft (group A) were compared with patients at low anatomic risk enrolled in a prospective multicenter trial (group B).
