The Coronavirus Disease (COVID-19) pandemic has contributed to a co-occurring psychiatric epidemic. Children and adolescents have been particularly impacted, with disruptions in continuity of learning and healthcare. Psychological stressors such as fear of infection, boredom, decreased socialization, supply shortages, and incomplete information have contributed to low mood, irritability, insomnia, and emotional exhaustion. Our study contributes to this research by quantifying the devastating psychiatric toll that t [...]

Pancreatic cancer is the fourth leading cause of death in the USA. Treatment is seldom successful. A wide variety of organotin polymers exhibit good inhibition of human pancreatic cancer cell lines AsPC-1 and PANC-1. The AsPC-1 is an adenocarcinoma pancreatic cell line and PANC-1 which is an epithelioid carcinoma pancreatic cell line. Synthesis is rapid employing commercially available reactants and the interfacial polymerization that is employed in the commercial synthesis of aramids and polycarbonates.

Lung transplantation in patients with end stage lung disease can improve survival and quality of life. Airway complication incidence varies between 2-33%, but the true incidence is difficult to determine due to a lack of validated classification systems. There are many risk factors for post lung transplant airway complications, the most common being anastomotic ischemia, pulmonary infections, surgical technique and allograph dysfunction. Common complications include formation of granulation tissue, anastomotic sten [...]

In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies, to include the printing and extrusion speed, a [...]

This work aimed at evaluating all products from the low-temperature pyrolysis (350°C) of some industrial wastes, cotton stems and seeds (CSS), grape husks and curls (GRH), undigested sewage sludge (USS) and their blends in a fixed bed system and suggesting their possible applications. Solid and liquid products, biochars, and bio-oils were analyzed using various techniques by physicochemical, mineralogical, and chemical analyses. Gases were qualitatively and quantitatively analyzed using a thermogravimetric-mass [...]

Teachers face at-work risk factors including compassion fatigue, burnout, dealing with violence, and a teacher shortage. A review of the literature shows that self-care can have positive benefits that mitigate and help to buffer these at-work risk factors This study examines teachers’ stories of self-care. The data suggests that self-care is a positive practice for teachers professionally and personally.

The current study aimed to investigate the effect of a multi-species probiotic (MSP) on cytokine production by human peripheral blood mononuclear cells (PBMCs) and their immune dialogue with HT-29 colon cancer cells. PBMCs were incubated with MSP and their effect on cell proliferation and TNFα, IL-1β, IL-2, IL-6, IFNγ, IL-10, and IL-1ra production was evaluated. The impact of MSP on the cytokine production by PBMC stimulated by HT-29 cells was detected. Not-stimulated PBMC incubated with MSP showed increased produc [...]

Fabrication, arrangement, and controllable composition of ordered organometallic films are critical for designing a highly active catalyst and investigating the catalytic mechanism. In this paper, an organometallic terpyridine Pd(II)/Ni(II) monolayer linked on the silicon substrate surface (denoted as Si-Tpy-Pd1/Ni1) was prepared and characterized using water contact angle, ultraviolet spectra, X-ray diffraction, scanning electron microscopy, and X-ray photoelectron microscopy. Si-Tpy-Pd1/Ni1 exhibited high catalyt [...]

Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) elders are vulnerable to both the “usual” types of elder abuse (physical, sexual, emotional, and financial abuse, along with neglect), and with abuse that is specific to the context and history of LGBTQ+ elders. Training for adult protective services, long-term care ombudsmen, and other professionals who work with abused elders therefore should include information and skill-building in responding to this population. Research into effective training about LGBTQ [...]
