Changes in ocular astigmatism with age: A longitudinal study
Authors: Beesley Jeremy , Elliott David B. 
Published: September 2023

AbstractPurposeTo investigate changes in astigmatism with age. Are changes from with‐the‐rule (WTR) in younger ages to against‐the‐rule (ATR) in older patients mediated through oblique astigmatic axes or spherical prescriptions, and at what ages do these changes occur?MethodsPrescription data were gathered retrospectively from one optical practice belonging to a large multiple group in the UK. Longitudinal assessments were made of the changes in astigmatism for 326 patients (mean age at first prescription 46 years, range 28–69 years) and 640 eyes through their recorded prescription history (median 20 years of prescription data per participant, IQR 19–22 years, range 18–29 years).ResultsChanges in small degrees of astigmatism (0.25 or 0.50 DC) from WTR to ATR were more than three times more likely to pass through an oblique cylinder axis as through a spherical prescription (56 vs. 16,  = 22.2, p < 0.0001). For patients aged 28–40 years at their first recorded eye examination, 55% (92/167) of eyes had an onset of astigmatic changes at a mean of 44 years (SD 6.2) and 41% (68/167) of eyes had no change until after a mean of 54 years (SD 4.6). Compared with a measured prevalence of oblique astigmatism in the literature of 11%–19%, 36% (232/640) of the eyes in this study had an oblique cylinder prescribed at least once in their refraction history and of these oblique cylinders, 78% were transient in nature.ConclusionsThe change in ocular astigmatism with age, from WTR to ATR, was more than three times more likely (56 vs. 16) to pass through oblique cylinder axes as through a spherical prescription. Changes in oblique astigmatism have been implicated in complaints with new spectacles, so given this prevalence of oblique cylinder axes (232/640, 36%), continuing professional development is needed regarding reconciling these oblique changes with previous prescriptions.

AbstractObjectivesThe objective of this study is to explore what ageing well means to older adults with bipolar disorder.MethodsOlder adults with bipolar disorder took photographs of aspects of their lives that they felt represented ageing well. They then completed audio‐recorded photo elicitation interviews to explore what it meant to age well with bipolar disorder in detail. Data were analysed using reflexive thematic analysis.ResultsSeventeen participants met the criteria for bipolar disorder I or II. The analysis resulted in four key themes to ageing well with bipolar disorder: (1) Lifelong learning – referring to how participants accumulated a wealth of knowledge about bipolar disorder and used this to maintain stability in later life; (2) Finding where you belong – relating to how participants prioritised finding new communities, utilised family support and refined their support networks over time to age well; (3) Recognising your value and worth – which involved participants using their strengths and experiences to support others; and (4) Continuity of support – older adults with bipolar disorder highlighted the benefits of continuous support that allowed them to be actively involved in their treatment.ConclusionsParticipants ageing with bipolar disorder identified unique challenges indicating that services require adaptation to meet their needs and support them to age well. Findings suggested that services should provide continuous care that allows this group to actively engage with their treatment, build upon their strengths, and develop meaningful connections with professionals and peers. This approach may enhance support for older adults with bipolar disorder and reduce the inequalities they experience.

AbstractObjectivesThis study aims to examine the correlation between environmental literacy and levels of awareness of global climate change in nursing students.DesignThe cross‐sectional and correlational design.Sample476 undergraduate nursing studentsMethodsData were collected with The Personal Information Form, the Awareness Scale of University Students about Global Climate Change, and Environmental Literacy Scale for Adults in March 2023. Descriptive statistics, correlation, and linear regression analysis (stepwise method) were used to analyze the data.ResultsThe mean scores of the Environmental Literacy Scale and the Awareness Scale of University Students about Global Climate Change Scale were 87.31 ± 8.61 and 75.60 ± 14.86, respectively. A positive correlation was found between the awareness of global climate change and environmental literacy (p < 0.05). As participation in meetings on environmental problems, environmental concerns and awareness increased, awareness of global climate change increased.ConclusionsNursing students had high levels of awareness of global climate change and environmental literacy. The awareness of nursing students on climate change and their environmental literacy levels are highly important in protecting public health against the adverse effects of climate change and reducing climate change through effective resource management in health services in the future. It is recommended that integrate courses related to environment health to curriculum of nursing school and in‐service training during healthcare. The study draws attention to the Sustainable Development Goals related to climate change.
Floor plan creation using a low‐cost 360° camera
Authors: Vynikal Jakub , Zahradník David 
Published: September 2023

AbstractThe creation of a 2D floor plan is an integral part of finishing a building construction. Legal obligations in different states often include submitting a precise floor plan for ownership purposes, as the building needs to be divided between new residents with reasonable precision. Common practice for floor plan generation includes manual measurements (tape or laser) and laser scanning (static or SLAM). In this paper, a novel approach is proposed using spherical photogrammetry, which is becoming increasingly popular due to its versatility, low cost and unexplored possibilities. Workflow is also noticeably faster than other methods, as video acquisition is rapid, on a par with SLAM. The accuracy and reliability of the measurements are then experimentally verified, comparing the results with established methods.

AbstractIn the postpartum period, there is an increase in non‐esterified fatty acids (NEFA) in both serum and follicular fluid (FF) of cattle. The increase in fatty acid concentration results in increased production of reactive oxygen species (ROS) that can compromise bovine fertility. The objectives of this study were to characterize the lipid profile found in the FF of cows experiencing induced negative energy balance (NEB) and to evaluate the effect of α‐tocopherol in the prevention of oxidative stress in the serum and FF of cows. Twenty‐nine beef cows were divided into groups: (1) control; (2) Fasting for 24 days; and (3) Fasting + VitE. Between D0 and D4 blood samples were taken to assess concentrations of NEFA, ROS production, total antioxidant capacity (FRAP), lipid peroxidation, and α‐tocopherol (vitamin E). On D4, follicular aspiration was performed for analysis of FF from the dominant follicle. Our results demonstrate that fasting was effective in causing increased fat mobilization in animals. The increase in serum concentration of C18:1c9 was reflected in the FF of fasting cows. Serum α‐tocopherol concentration was higher in the control and Fasting + VitE groups compared to the Fasting group. In FF, there was an increase of α‐tocopherol in the Fasting + VitE group in comparison to Fasting cows. There was an increase in ROS production in the serum of fasting cows. ROS production in FF was higher in the Fasting compared to the Fasting + VitE group. Vitamin E has beneficial effects in reducing ROS production in the dominant follicle of cows in NEB.
The role of explanatory context for racial disparities in predicting sociopolitical attitudes during COVID‐19

Published: September 2023

AbstractThe COVID‐19 pandemic placed preexisting racial health disparities in stark relief. Recent studies have already established that, among prejudiced Whites, exposure to such racial disparities reduced concern about the pandemic and support for mitigation policies (Harrel & Lieberman, 2021; Stephens‐Dougan, 2022). In response to such results, one cautionary line of reasoning argues that communicating the disparity figures without explanatory context can perpetuate (or at least not undermine) myths that African Americans are more likely to contract COVID‐19 due to genetic predispositions or maladaptive behavioral tendencies (Chowkwanyun & Reed, 2020). In two studies, we test the claims that (a) explanatory context mitigates the tendency to attribute racial disparities to essential racial differences and (b) that perceptions of racial disparities are attuned to specific racial inequalities in the U.S., and not merely expressions of outgroup bias. In Study 1, we found that exposure to racial disparities with explanatory context (vs. without explanatory context) did not reduce racial essentialism or stereotyping, but did promote support for healthcare equity. In Study 2, we found that black disadvantage frames (vs. white vs. Hispanic) uniquely promoted support for equitable healthcare and multicultural inclusion. Importantly, and contrary to other recent findings, exposure to black disadvantage did not preclude support for equity.
Pandemic precarity: A multi‐level study of neoliberal precarity and COVID‐Related outcomes in the United States
Authors: Schmitt Harrison J. , Jimenez Tyler , Young Isaac F. 
Published: September 2023

AbstractNeoliberalism is the political‐economic system that has characterized the United States for the past half century. Structurally, neoliberalism has involved privatization, deregulation, and government divestment from public health systems. Cultural psychologists have begun to outline the ways that neoliberalism is reflected in attitudes, ways of being, and ideologies, such as in the form of heightened individualism, justification of inequality, depoliticization, and precarity. We argue that neoliberal structures and psychologies may contribute to deleterious outcomes in the context of the COVID‐19 pandemic. We demonstrate that neoliberalism at the US state level (n = 51) is associated with higher COVID mortality and case fatality rates, as well as lower vaccination rates (Study 1). We also demonstrate that individual‐level (n = 8280) neoliberal ideology predicts less adaptive beliefs and attitudes such as the belief that the federal response to the pandemic was too fast and belief in COVID‐related misinformation (Study 2). We demonstrate using multilevel modeling that state‐level neoliberalism predicts individual‐level COVID‐related attitudes, which is explained in part by heightened neoliberal ideology in more neoliberal states (Study 2). This study contributes to an understanding of the structural and cultural psychological factors that have contributed to the severity of the COVID‐19 pandemic in the US.

AbstractObjectiveTo determine intraocular pressure (IOP) and tear production, as well as to compare the IOP obtained with the TonoVet Plus® (rebound) with the Tono‐Pen Avia® (applanation) tonometers.AnimalsTwenty‐five Mini Lionhead rabbits (n = 50 eyes).ProcedureTear production was measured at 6:00 a.m. and 6:00 p.m. by using the STT. The IOP reading was performed with the rebound tonometer, followed by the applanation tonometer, at 6:00 a.m., 9:00 a.m., 12:00 p.m., 3:00 p.m., and 6:00 p.m. Regression analysis, analysis of variance (anova) and Bland–Altman statistics were used.ResultsDaily tear production was 10.25 ± 3.75 mm/min, with no differences among the moments evaluated. Average daily IOP was 17.7 ± 3.08 mmHg with the TonoVet Plus® and 11.5 ± 4.56 mmHg with the Tono‐Pen Avia®. IOP values were higher at the beginning and end of the day with both tonometers.ConclusionThe IOP values are higher with the TonoVet Plus® tonometer. The reference values of IOP and tear production obtained in this work may support the diagnosis, treatment, and monitoring of ocular disorders in pet Mini Lionhead rabbits.

Analysis of Wave Force and Run-Up Acting on an Impermeable Vertical Circular Cylinder Surrounded by Multiple Thick Porous Layers
Authors: Saha Sunanda , Nandan Bora Swaroop 
Published: September 2023

Abstract
In this work, we analyze the effect of multiple thick porous layers, fitted around a rigid vertical circular cylinder, on the wave forces acting on the rigid structure. Using the eigenfunction expansion method in cylindrical coordinates, we derive the expressions for velocity potentials in the respective domains and finally calculate the wave force acting on the rigid structure by integrating the pressure term. Consideration of the multiple porous layers, each with different porosities, gives rise to a very basic question to answer: what will be the appropriate arrangement of the porous layers to reduce the wave impact? Hence, for numerical study, we consider three different arrangements of the porous layers. For such arrangements of the porous layers, we also analyze the effects of the other crucial parameters, such as the number and the thickness of the porous layers, on the wave force. The key finding of the analysis is that the wave force acting on the rigid structure can be minimized by increasing the number of porous layers with decreasing porosity from the innermost layer to the outermost layer. The wave breaking and forced oscillations for certain values of the porous impedance parameter are some of the interesting observations. The present model is also verified against an existing work in the literature which shows an excellent agreement.
Urban Airflow Analysis Using Reduced-Order Modeling
Authors: Sharma Shivesh N. , Goudarzi Navid 
Published: September 2023

Abstract
The numerical and experimental techniques are widely used for urban air flow studies. As spatiotemporal scales increase, these models face an extended range of limitations, from the experimental setup sizing/equipment constraints to expensive physics-based computational modeling. Reduced order models (ROMs) are introduced as an alternative or a complementary tool to current practices for identifying urban airflow characteristics. This paper investigates the implementation of a group of ROMs on an opensource experimental dataset. These models follow two major steps dimensionality reduction and airflow feature computation. The results show a significant reduction in the computational cost with similar accuracy achieved when studying urban airflow characteristics to those from experimental testing. These models can be further used in urban climate analysis.
Energy Mix Forecasting: A Techno-Economic Analysis to Guide U.S. Power Production Decisions Through 2100
Authors: Keenan Michael , Brooks Joshua , Duncan Scott 
Published: September 2023

Abstract
With advancing technology, growing population, and increased accessibility, there is an ever-growing need for energy to power our world. Meeting the increased demand is challenged by stringent environmental constraints and the time to implement new energy sources, all while doing so in a cost-efficient manner. To assist decision makers in forecasting what the energy production future should look like, a framework is developed that can account for these factors. With flexible parameters for power production assets and energy constraints, varying energy mixes can be evaluated against each other. Through two initial investigations, this advises that changes to the energy mix begin to occur sooner rather than later to reduce long term costs and emissions. With the tuning of this framework, specific energy mix prediction cases can be assessed and utilized by decision makers to guide investment and policy for the far future.
An Innovative Seal Concept for Aircraft Engines

Published: September 2023

Abstract
Today, both the government and private aircraft companies strive for faster, lighter, and less expensive aircraft to stay competitive in both the national and international arena. This is only possible with continuous innovation and sustainability efforts for aircraft systems such as fans, compressors, combustors, and turbines, as well as the sub-systems including engine seals. Advanced engine seals show significant promise for improving the engine pressure ratio and cycle temperatures, which result in lower engine weight, stronger thrust, and higher fuel efficiency. We propose an innovative multistage seal concept that leverages the well-known Elastohydrodynamic (EHD) lubrication theory. In this study, a physics-based computer simulation modeling approach was employed. Due to the highly non-linear nature of the complex Fluid-Solid-Interactions (FSI) between the seal and the rotor, a fully coupled Finite Element Analysis (FEA)-Computational Fluid Dynamics (CFD) based modeling was adopted for the design of the seal system. With the recent improvements in the commercially available software, COMSOL Multiphysics software was employed to carry out the fully coupled FSI simulations. The modeling approach was presented thoroughly, and the results were discussed. The leakage was found to be less than 0.010 kg/s at 2.75 MPa. The proposed seal system could be an alternative to the existing sealing technologies in the market.
Renewable Power Recovery System Using Main Steam Condenser
Authors: Muldoon Thomas J. 
Published: September 2023

Abstract
Power plants are designed to discharge a significant amount of energy to the ambient environment with much of this discharge occurring through the main steam condenser. When condensers operate with lower than design temperature water or air, they produce a substantially improved capacity until other factors limit their performance such as steam velocities. Instead of modulating flow, the tubes can be segregated into condenser halves. In one half, the surface is operating at full load, as a standard steam condenser heating the cooling water or air while the other half of the surface evaporates a refrigerant. This refrigerant can then be drawn through another low pressure turbine to recover energy before being condensed in a separate condenser. This Condenser for Power Recovery System (CPRs) is a bottom cycling is based on one of several optional fluids and is described by a recent US Patent US10,577,986 B2.
Design/Development of an Ultra-Compact Jet Impingement Thermal Management System Integrated With Micro-Fins for High Power Applications: A CFD Modeling

Published: September 2023

Abstract
Gallium Nitride (GaN) high electron mobility transistors (HEMTs) are attracting attention, especially due to their high power densities. However, their performance is limited due to resulting temperature rise, which requires thermal management systems (TMS). Different methods have been proposed, including high thermal conductivity substrates, GaN-specific packaging solutions, and heat spreaders. In this study, the proposed ultra-compact jet impingement (UJI) TMS includes a single or array of jets impinging the heat transfer fluid (HTF) to the GaN package base plate, with an arrangement of fins to increase the effective surface area. A parametric study is performed to develop a mathematical model for the design of UJI-TMS integrated with micro-fins. The computational fluid dynamics (CFD) modeling for a single array of nozzles integrated with and without fins were performed. The system’s performance was evaluated under 1 kW/cm2 heat flux. The results from the analysis of the optimized geometry including array of nozzles integrated with fins, showed an average temperature of around 38 °C for the surface of the package.
