Fe-rich alloys have been widely studied as catalyst materials for the cathodic oxygen reduction reaction (ORR) in hydrogen fuel cells, and many have shown high activities. The stability of Fe-rich catalysts has also been researched, and some studies have shown promising results using an accelerated stress test (AST), which uses a potential cycling method. However, for commercial fuel cell applications, such as standby power systems, the catalyst has to tolerate a high potential for a long period, which can not be r [...]

Recently, numerous studies have reported convincing data suggesting that chromosome instability may be not only a trigger of cancers but a possible mechanism for a wide spectrum of brain diseases. According to our original experience, chromosome instability is commonly observed during karyotyping of children with neuropsychiatric diseases and congenital malformations. To understand mechanisms of non-cancerous diseases potentially mediated by chromosome instability, which may represent an important target for molecu [...]

In this paper, we continue our previous work by discussing the consequences of curvature in spacetime caused by the presence of mass and the implications of this. We address the question raised by Dirac regarding the impact of a magnetic monopole on the quantum world. We discuss quantization concerning the solid angles observed, which may have a connection with a magnetic monopole.

Background: Post-secondary students are at increased risk for sleep problems and poor eating behaviours that overtime may lead to negative health outcomes later in life. However, limited research has examined associations of sleep quality with eating behaviours and eating competence (e.g., being positive, flexible, and comfortable with eating and getting enough enjoyable and nutritious foods) among Canadian post-secondary students. Methods: Using a cross-sectional study design, participants completed an online surv [...]

Mind-body interventions have shown promise for improving prenatal mental health. The purpose of this study was to investigate the feasibility of a prenatal mind-body intervention delivered remotely due to COVID-19 and preliminary efficacy with respect to mental health outcomes. This study used a simultaneous mixed methods approach (n = 27). Mixed methods data were collected to evaluate the feasibility and preliminary efficacy of the remotely delivered program (I.e., acceptability, practicality, demand, sustainabili [...]

Aim: The purpose of this study was to evaluate faculty and student perceptions of a fall risk assessment and prevention activity for older adults offered in multiple community settings by health professional faculty and students. Background: In the US, the percentage of adults 65 and older who fell was more than 29% in 2018. Among states, Arkansas ranks 48th with 35.2% of older adults reporting a fall (CDC Behavioral Risk Factor Surveillance System, 2018). Methods: Four senior centers in Northwest Arkansas hosted a [...]

Iron doped ZnO (Fe-ZnO) nanoparticles were synthesized using two techniques that are economical as well as scalable to yield tunable properties of nanoparticles for facilitating down conversion in an absorbing layer of a solar cell. To evaluate the suitability of Fe-ZnO nanoparticles prepared by two deposition methods, we present a comparison of optical, electrical, and structural properties of Fe-ZnO using several experimental techniques. Structural properties were analyzed using transmission electron microscopy a [...]

Compassion Focused Therapy (CFT) has increasingly been shown to have a positive impact for people experiencing a range of difficulties, and online self-help formats could provide a way of increasing its accessibility and scalability. This study explored adult participants’ subjective experiences of engaging with online self-compassion training drawn from Compassionate Mind Training (CMT) and CFT. Semi-structured interviews were conducted with 15 participants who had completed online self-compassion training, [...]

Background: Pneumocystis jirovecii colonization in patients is associated with a low organism burden, which supports the need to use highly sensitive molecular techniques, such as nested-PCR to determine the presence of the organism. However, few studies have considered the effect of nucleic acid extraction methods on the detection of P. jirovecii. Here, we evaluate how pre-treatment affects microbial detection. Methods: Lung tissue samples from fifteen autopsied infants were processed using two different DNA extra [...]
