Delving into the permeability evolutionary patterns of fractured rock masses in fault zones under seepage-stress coupling holds great significance for the prevention and control of water inrushes along faults from coal seam floors.Methods Against the engineering background of the Gaohe Coal Mine under the Shanxi Lu’an Mining (Group) Co., Ltd. in Shanxi Province, this study analyzed the microscopic physical properties and the pore and fracture structures of a fractured rock mass in a …

Mental Health In Prisons: Examining Variations In Disorders Across Custody Levels, Ariel Bysiek

Dissertations and Theses

The United States has a significantly large prison population with the number of people currently in a correctional facility being 1.9 million. Concern has been increasingly growing related to treatment of individuals in prison, particularly when it comes to solitary confinement. Many people believe that solitary confinement is unnecessarily cruel and debilitating to AIC's mental health. Studies have found contradicting information as to whether solitary impacts mental health. Part of the reason for this contradiction stems from the lack of measurement systems that are appropriate for AICs. The measures used in studies are meant for the general population, not individuals …

Dwelling, Kelly Erin Mclysaght

Dissertations and Theses

dwelling explores the network of connections between time, the self, and physical space. People and place are layered, and memories haunt these blurred spaces. Poems follow several lines of questioning: what lingering presence does abuse leave in the body and in the home? Is it possible to inhabit and share space with these presences, and if so, what does that mean for identity, relationships, and safety? Through repetition, image, and syntax, dwelling constructs a maze, enacting the conflicting desire to both linger in memory and run from it, holding the haunting beauty of grief and loss alongside anger and alienation.

Electromyographic Analysis Of Lower Limb Muscles During Multi-Joint Eccentric Isokinetic Exercise Using The Eccentron Dynamometer, Brennan J. Thompson, Merrill Ward, Brayden Worley, Talin Louder

Kinesiology and Health Science Faculty Publications

Eccentric muscle actions are integral to human movement, rehabilitation, and performance training due to their characteristic high force output (overload) and low energy cost and perceived exertion. Despite the growing use of eccentric devices, a gap in the research exists exploring multi-muscle activation profiles during multi-joint eccentric-only, isokinetic exercise. This study aimed to quantify and compare surface electromyographic (EMG) activity of four leg muscles—vastus lateralis (VL), tibialis anterior (TA), biceps femoris (BF), and medial gastrocnemius (GM)—during a standardized (isokinetic) submaximal eccentric multi-joint exercise using the Eccentron dynamometer. Eighteen healthy adults performed eccentric exercise at 40% of their maximal eccentric strength. …

2020-Current year OA Pubs

BACKGROUND: Wearable movement sensors can measure upper limb (UL) activity, but single variables may not capture the full picture. This study aimed to replicate prior work identifying five multivariate categories of UL activity performance in people with stroke and controls and expand those findings to other UL conditions.

METHODS: Demographic, self-report, and wearable sensor-based UL activity performance variables were collected from 324 participants (stroke

RESULTS: Two PCs explained 70-90% variance: PC1 (overall UL activity performance) and PC2 (preferred-limb use). A five-variable, five-cluster model was optimal across samples. In comparison to clusters, two PCs and individual accelerometry variables showed higher convergent …

A Study Of The Atangana Baleanu Fractional Differential Equation With An Application In Gas Dynamic Problem, Amjad Shaikh, Shashikant Waghule, Dinkar Patil, Kottakkaran Sooppy Nisar

Baghdad Science Journal

This article presents an analytical approximation for the nonlinearity of the fractional order gas dynamics equation in both homogeneous and nonhomogeneous cases, with a particular emphasis on shock fronts. The approach utilizes the fractional differentiation operator proposed by Atangana and Baleanu. By employing this operator, an approximate solution for the fractional order gas dynamic equations in scenarios involving shock fronts is derived. The solution process primarily involves an iterative procedure that leverages the Laplace transform for numerical computations. The use of the Laplace transform minimizes round-off errors, resulting in a solution that is both precise and straightforward to implement. The …

Relationship Between Participation In Employee Wellness Programs And Health-Related Quality Of Life Among Health Care Workers, Ana Williams

Walden Dissertations and Doctoral Studies

Employee wellness programs are available in many health care organizations but remain underutilized by health care workers. Low employee participation in these wellness programs can negatively impact employees’ health-related quality of life (HRQoL), which, in turn, may adversely influence patient care and overall health outcomes. Despite this, little is known about which factors, such as perceived barriers and benefits, job category, or work shift, are associated with participation. This study addressed that gap by exploring how these variables relate to employee engagement in wellness programs and their potential impact on HRQoL. Guided by the health belief model, this study examined …

This study explores the relationship between hand grip strength (HGS) and cognitive function in China’s middle-aged and elderly population. We employed a cross-sectional design using data from 4535 participants aged ≥ 45 years from the 2015 China Health and Retirement Longitudinal Study national dataset. The relationships between HGS and various dimensions of cognitive function, as well as the association between HGS and cognitive impairment, were investigated using ordinary least squares regression models and logistic regression models. Dose–response relationships between HGS and cognitive impairment were modeled using restricted cubic spline curves. Subgroup and sensitivity analyses were performed to assess the robustness …

Enhancement Of Ultrasonic Welding Of Bulk Carbon Nanotube-Metallic And Graphene-Metallic Conductors, Daniel L. Broderick

Theses

Nanostructured carbon sheets comprising carbon nanotube (CNT) or graphene are appealing for electrode and antenna applications. Physical connection to metal conductors requires enhanced mechanical strength, electrical performance, and thermal capability. Ultrasonic welding is a viable technique to fabricate stable and robust bonds but requires methods to further reduce electrical resistance and improve mechanical strength. The present dissertation has advanced ultrasonic welding between bulk CNT electrodes and Cu foil by utilizing chemically doped junctions at the bond interface. Specifically, a selective doping strategy using KAuBr4 at the bonding regions between bulk CNT electrodes and Cu lowers the electrical contact resistance measured …
