Structure and Conductivity in LISICON Analogues within the LiGeO-LiMoO System.

New solid electrolytes are crucial for the development of all-solid-state lithium batteries with advantages in safety and energy densities over current liquid electrolyte systems. While some of the best solid-state Li-ion conductors are based on sulfides, their air sensitivity makes them less commercially attractive, and attention is refocusing on air-stable oxide-based systems. Among these, the LISICON-structured systems, such as LiZnGeO and LiVGeO, have been relatively well studied.

Local Structure in α-BIMEVOXes (ME = Ge, Sn).

The BIMEVOXes are among the best oxide ion conductors at low and intermediate temperatures. Their high conductivity is associated with local defect structure. In this work, the local structures of two BIMEVOX compositions, BiVGeO and BiVSnO, are examined using total neutron and X-ray scattering methods, with both compositions exhibiting the ordered α-phase at 25 °C and the disordered γ-phase at 700 °C.

Under the influence of nature: The contribution of natural capital to tourism spend.

Tourism and outdoor leisure is an important economic sector for many countries, and has a substantial reliance on natural capital. Natural capital may be the primary purpose for tourism, or it may be a secondary factor, where the choice of location for a leisure activity is influenced by natural capital. Typically, when valuing tourism and outdoor leisure, all expenditure associated with the activity is assigned to the ecosystem it occurs in.

Phase behaviour of ammonium bromide-under high pressure and low temperature; an average and local structure study.

We revisit the pressure-induced order-disorder transition between phases II and IV in ammonium bromide-using neutron diffraction measurements to characterise both the average and local structures. We identify a very sluggish transition that does not proceed to full conversion and local structure correlations indicate a slight preference for ammonium cation ordering along ⟨110⟩ crystallographic directions, as pressure is increased. Simultaneous cooling below ambient temperature appears to facilitate the pressure-induced transition.

Bright spots as climate-smart marine spatial planning tools for conservation and blue growth.

Marine spatial planning that addresses ocean climate-driven change ('climate-smart MSP') is a global aspiration to support economic growth, food security and ecosystem sustainability. Ocean climate change ('CC') modelling may become a key decision-support tool for MSP, but traditional modelling analysis and communication challenges prevent their broad uptake. We employed MSP-specific ocean climate modelling analyses to inform a real-life MSP process; addressing how nature conservation and fisheries could be adapted to CC.

Effectiveness of Educating Health Care Professionals in Managing Chronic Pain Patients Through a Supervised Student Inter-professional Pain Clinic.

Objective: To address the need for increased and more effective medical education regarding chronic pain and pain management, an inter-professional (IP) training program in the form of a supervised student IP pain clinic was implemented in 2016. In the current study, we evaluated its feasibility and effectiveness in improving health care professional students' skills in (1) managing chronic pain and (2) working in an IP team.

Methods: From January 2016 to December 2018, we assembled 12 IP teams that included students from the following six professions at the University of New England: nursing, osteopathic medicine (OM), occupational therapy (OT), pharmacy, physical therapy (PT), and social work (SW).

Improving patient-provider communication about chronic pain: development and feasibility testing of a shared decision-making tool.

Background: Chronic pain has emerged as a disease in itself, affecting a growing number of people. Effective patient-provider communication is central to good pain management because pain can only be understood from the patient's perspective. We aimed to develop a user-centered tool to improve patient-provider communication about chronic pain and assess its feasibility in real-world settings in preparation for further evaluation and distribution.

Evaluation of Using the Sphygmomanometer Test to Assess Pain Sensitivity in Chronic Pain Patients vs Normal Controls.

Objectives: Objectively measuring pain sensitivity has not been easy in primary care clinics. A sphygmomanometer test (a sensory test that measures an individual's nociceptive response to pressure using a standard blood pressure cuff) has recently been established to test pain sensitivity. Here, we examined the feasibility of using the sphygmomanometer test with chronic pain patients.

Cost Analysis of Dual-Mobility Constructs in Revision Total Hip Arthroplasty: A European Payer Perspective.

Dual-mobility constructs have been shown to significantly and substantially decrease dislocations after revision total hip arthroplasty (THA). The authors have previously shown that dual-mobility (DM) constructs are cost-effective given their ability to decrease dislocations and re-revision for dislocation. The goal was to report the costs of DM and large femoral head (LFH) constructs in revision THAs from a European health care payer perspective.

Combatting Sedentary Lifestyles: Can Exercise Prescription in the Emergency Department Lead to Behavioral Change in Patients?

Introduction Emergency department (ED) patients with chronic disease are known to benefit from exercise; however, there are few studies examining the prescription of exercise in the ED. We asked, is exercise prescription in the ED feasible and effective? Methods In this pilot prospective block randomized trial, consented patients were divided into control and intervention groups. The control group received routine care.

Defect structure in δ-BiPbYO.

A detailed study of the defect structure in a di-substituted δ-BiO type phase, δ-BiPbYO, is presented. Using a combination of conventional Rietveld analysis of neutron diffraction data, reverse Monte Carlo (RMC) analysis of total neutron scattering data and molecular dynamics (MD) simulations, both average and local structures have been characterized. δ-BiPbYO represents a model system for the highly conducting δ-BiO type phases, in which there is a higher nominal vacancy concentration than in the unsubstituted parent compound.

Investigation of Antisite Defect Formation and Chemical Expansion in LiNiPO by in Situ Neutron Diffraction.

In situ neutron diffraction was used to characterize the effect of temperature on the crystal structure of LiNiPO. LiNiPO adopts an ordered olivine structure at room temperature, but, with increasing temperature, this work shows that a significant amount of Li and Ni cation exchange occurs, for example, ∼15% at 900 °C. The antisite disorder is detected by residual nuclear densities on the M1 and M2 octahedral sites in the olivine structure using difference Fourier maps and by changes in cation site occupancies, lattice parameters, and mean ⟨M-O⟩ bond distances.

Pioglitazone protects HDL(2&3) against oxidation in overweight and obese men.

Background: The worldwide epidemic of obesity is a major public health concern and is persuasively linked to the rising prevalence of diabetes and cardiovascular disease. Obesity is often associated with an abnormal lipoprotein profile, which may be partly negated by pioglitazone intervention, as this can influence the composition and oxidation characteristics of low-density lipoprotein (LDL). However, as pioglitazone's impact on these parameters within high-density lipoprotein (HDL), specifically HDL(2&3), is absent from the literature, this study was performed to address this shortcoming.

A dipole polarizable potential for reduced and doped CeO(2) obtained from first principles.

In this paper we present the parameterization of a new interionic potential for stoichiometric, reduced and doped CeO(2). We use a dipole polarizable potential (DIPPIM: the dipole polarizable ion model) and optimize its parameters by fitting them to a series of density functional theory calculations. The resulting potential was tested by calculating a series of fundamental properties for CeO(2) and by comparing them against experimental values.

Challenges in converting an interviewer-administered food probe database to self-administration in the National Cancer Institute Automated Self-administered 24-Hour Recall (ASA24).

The National Cancer Institute (NCI) is developing an automated, self-administered 24-hour dietary recall (ASA24) application to collect and code dietary intake data. The goal of the ASA24 development is to create a web-based dietary interview based on the US Department of Agriculture (USDA) Automated Multiple Pass Method (AMPM) instrument currently used in the National Health and Nutrition Examination Survey (NHANES). The ASA24 food list, detail probes, and portion probes were drawn from the AMPM instrument; portion-size pictures from Baylor College of Medicine's Food Intake Recording Software System (FIRSSt) were added; and the food code/portion code assignments were linked to the USDA Food and Nutrient Database for Dietary Studies (FNDDS).

Assessment of the accuracy of portion size reports using computer-based food photographs aids in the development of an automated self-administered 24-hour recall.

Objective: To assess the accuracy of portion-size estimates and participant preferences using various presentations of digital images.

Design: Two observational feeding studies were conducted. In both, each participant selected and consumed foods for breakfast and lunch, buffet style, serving themselves portions of nine foods representing five forms (eg, amorphous, pieces).

Neutron total scattering study of the delta and beta phases of Bi2O3.

The highly disordered structure of the delta phase of Bi2O3, which possesses the highest known oxide-ion conductivity, has been studied using neutron powder diffraction. A detailed analysis of data collected at 1033(3) K using Rietveld refinement indicates that the time-averaged structure of delta-Bi2O3 can be described using the accepted model of a disordered, anion-deficient fluorite structure in space group Fm3m. However, reverse Monte Carlo modelling of the total (Bragg plus diffuse) scattering demonstrates that the local anion environment around the Bi3+ resembles the distorted square pyramidal arrangement found within the stable alpha and metastable beta phases at ambient temperature, which is characteristic of the cation's 6s2 lone-pair configuration.
