3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications (open access)

3D Printed Self-Activated Carbon Electrodes for Supercapacitor Applications

This study investigated a new approach to achieving high energy density supercapacitors (SCs) by using high surface area self-activated carbon from waste coffee grounds (WCGs) and modifying 3D printed electrodes' porous structure by varying infill density. The derived activated carbons' surface area, pore size, and pore volume were controlled by thermally treating the WCGs at different temperatures (1000˚C, 1100˚C, and 1200˚C) and post-treating with HCL to remove water-soluble ashes and contaminants that block activated carbon pores. Surface area characterization revealed that the carbon activated at 1000˚C had the highest surface of 1173.48 m2 g-1, and with the addition of HCL, the surface area increased to 1209.35 m2 g-1. This activated carbon was used for fabricating the electrodes based on the surface area and having both micropores and macropores, which are beneficial for charge storage. Direct ink writing (DIW) method was utilized for 3D printing SC electrodes and changing the electrode structure by increasing the infill densities at 30%, 50%, and 100%. Upon increasing the infill densities, the electrodes' mass increased linearly, porosity decreased, and the total surface area increased for the 30% and 50% infill electrodes but decreased for the 100% infill electrode. Cyclic voltammetry (CV) test on the assembled …

Accessibility and Pedagogical Value in Virtuosic American Trombone Solo Literature: A Performance Guide to "Divertimento for Trombone and Band" (2012) by Jack Stamp (open access)

Accessibility and Pedagogical Value in Virtuosic American Trombone Solo Literature: A Performance Guide to "Divertimento for Trombone and Band" (2012) by Jack Stamp

This dissertation is an examination of Divertimento for Solo Trombone and Wind Band by renowned wind band composer and conductor Jack Stamp. The result of this study is the illumination of a 21st-century composition for solo trombone and band that is made accessible for future performers, accomplished by constructing original musical exercises that are influenced by current trombone pedagogical materials that have either been edited, annotated or created by current performers and pedagogues such as Joseph Alessi, Brad Edwards and Michael Mulcahy. The piece also incorporates 20th -century American wind band influences. The careful selection of pedagogical materials serves the purpose of making this challenging solo accessible for the advanced academic trombonist and can serve as a template for surveying advanced literature of the present and future. Additionally, the pedagogical materials selected for use in this dissertation were considered based on their value in the present academic trombone repertory. Thus, this performance guide reflects on the validity of the modern trombone pedagogical literature to guide a performer's study, interpretation, and performance of a 21st-century work for solo trombone.

Acculturation and Locus Of Control: Their Relationship to the Use of Inhalants (open access)

Acculturation and Locus Of Control: Their Relationship to the Use of Inhalants

This study analyzed the effects of acculturation, locus of control, and incidence of inhalant use on Mexican Americans. Information was collected from 275 subjects at three middle schools and one treatment center. The instrument consisted of Levenson's Locus of Control Scale, the Acculturation Rating Scale for Mexican Americans, and an incidence of use and family relationship questionnaire developed for this study. Statistical analysis indicated a relationship between acculturation and inhalant use. Further examination revealed relationships between a family members' use and subjects' inhalant use; subjects' alcohol use and inhalant use; and subjects' marijuana use and inhalant use. Information implied that prevention and intervention programs should focus on children of substance users and further research is needed surrounding the role of acculturation.

Adoption of Innovation in a Community College Environment: User Perceptions of Virtual Reality (VR) Technology among Students Studying Emergency Medical Service (EMS) (open access)

Adoption of Innovation in a Community College Environment: User Perceptions of Virtual Reality (VR) Technology among Students Studying Emergency Medical Service (EMS)

This research study examined the implementation of an extended reality (XR) lab on a community college campus to facilitate student and faculty access to immersive learning resources. The study, conducted during one skills day, involved 46 students and was designed to understand if integrating immersive VR into emergency medical technician (EMT) education could enhance learner confidence and motivation, develop problem-solving and analytical thinking skills, and thus connecting the classroom learning with real-world application. The majority of participants reported increased motivation and engagement, alongside improvements in learning outcomes like knowledge retention and skill development. Applying the unified theory of acceptance and use of technology (UTAUT) model revealed performance expectancy, effort expectancy, social influence, and facilitating conditions as key determinants of VR adoption in EMT education. While no significant overall performance enhancement was observed, VR training showed potential to boost motivation, confidence, and specific performance aspects. Furthermore, student perceptions towards VR in EMT education were largely positive, thereby suggesting its utility in immersive scenario training, skill acquisition in a risk-free environment, enhancing learner engagement, and real-world situational preparedness. VR demonstrated promise as a transformative tool in EMT education, necessitating further research to fully exploit its potential in diverse learning environments.

Adult Attachment, Racial-Ethnic Identity, Racial-Ethnic Socialization, and Subjective Wellbeing

The current study aimed to explore the direct effect of insecure adult attachment on subjective wellbeing and its indirect effect via racial-ethnic identity. Additionally, the present study examined the extent to which racial-ethnic socialization practices may moderate adult attachment and racial-ethnic identity link. The final sample included 213 emerging adults (M = 20.94; SD = 2.96) with diverse racial-ethnic backgrounds. PROCESS Model 4 and 1 were used to examine the direct and indirect effect of insecure attachment on subjective wellbeing via racial-ethnic identity variables and the interaction effect between insecure attachment and racial-ethnic socialization on racial-ethnic identity variables. Results indicated the direct effect of insecure attachment on subjective wellbeing but did not support hypotheses for the indirect effect of insecure attachment on subjective wellbeing via the racial-ethnic identity variables. Additionally, results indicated that overt socialization buffered the negative impact of attachment avoidance on racial-ethnic identity exploration. Furthermore, racial-ethnic identity variables and subjective wellbeing significantly differed across racial-ethnic groups and socioeconomic statuses. Findings provide insight on the distinct concepts of attachment and racial-ethnic identity as they highlight inter- and intra-personal components, respectively. Mental health professionals may utilize overt socialization to help clients develop a sense of purpose and meaning related to …

Air Breathing Fish: Development of Air Breathing in Bristlenose Plecos (Ancistrus cirrhosus) (open access)

Air Breathing Fish: Development of Air Breathing in Bristlenose Plecos (Ancistrus cirrhosus)

The bristlenose pleco (Ancistrus cirrhosus) is a species of armored catfish in the Loricariidae family that breathes air facultatively when the aquatic environment becomes hypoxic. The bristlenose pleco uses its highly vascularized stomach as an air breathing organ. The two main goals of this developmental study were to determine the size of onset of air breathing and to determine the frequency of air breathing behavior in bristlenose plecos from juveniles to adults. Developing juveniles reach functional maturity within four to six months of hatching and grow to an adult size of eight to ten cm in length. To examine the developmental timing for the onset of air breathing, we tested different sized juveniles beginning at one cm up until 8 cm in length. The developmental timing for the onset of air breathing was measured by exposing each fish to a slowly decreasing aquatic oxygen content from 100% air saturation down to 8% air saturation. Fish were first able to breathe air at just over 2 cm and 1 gram in mass. There was a weak negative correlation between fish length and % air saturation at which air breathing began. When exposed to 15% air saturation, frequency of air breathing was …
