Nitrogen oxide (NOx) emissions cause significant impacts on the environment and must therefore be controlled even more stringently. This requires the development of cost-effective removal strategies which simultaneously create value-added by-products or energy from the waste. This study aims to treat gaseous nitric oxide (NO) by hollow-fibre membrane biofilm reactor (HFMBfR) in the presence of nitrite (NO2-) and evaluate nitrous oxide (N2O) emissions formed as an intermediate product during the denitrification process. Accumulated N2O can be utilised in methane oxidation as an oxidant to produce energy. selleck products In the first stage of the study, the HFMBfR was operated by feeding only gaseous NO as the nitrogen source. During this period, the best performance was achieved with 92% NO removal efficiency (RE). In the second stage, both NO gas and NO2- were supplied to the system, and 91% NO and 99% NO2- reduction were achieved simultaneously with the maximum N2O generation of 386 ± 31 ppm. Lower influent carbon to nitrogen (C/N) ratios, such as 4.5 and 2.0, and higher NO2--N loading rate of 158 mg N day-1 favoured N2O generation. An improved NO removal rate and N2O accumulation were seen with the increasing amount of PO43- in the medium. The 16S rDNA sequencing analysis revealed that Alicycliphilus denitrificans and Pseudomonas putida were the dominant species. The study shows that an HFMBfR can be successfully used to eliminate both NO2- and gaseous NO and simultaneously generate N2O by adjusting the system parameters such as C/N ratio, NO2- and PO43- loading.The COVID-19 pandemic, with its disproportionate health and social-economic effects on the African American community, mandates bold new models to ensure that vulnerable communities receive maximum support and services. This article highlights a social work practice innovation model adapted from a traditional social work casework model. A group of multidisciplinary leaders strategized about ways to meet the needs of older African-American adults as many traditional government agencies were not sending staff into the community due to COVID-19. The result birthed a faith-based virtual health ministry.Using a faith-based virtual health ministry, church lay leaders and other professionals partnered with Master of Social Work (MSW) level social workers using a telehealth platform with technology tools to assist shut-in older adults in Washington, DC. The project uses a structured, coordinated care telehealth support model for a marginalized population. Telehealth within the rubric of healthcare models has not been demonstrated in African American communities, particularly older adults. Meeting the needs of shut-in older adults and marginalized groups within the COVID-19 pandemic may show innovation that can be translational for local governments and traditional safety net providers within a social work milieu.
Migraine is a common disease worldwide and migraine prevention is primarily currently based on pharmaceuticals. The mechanism of Vitamin B2 may positively contribute to migraine. This systematic review and meta-analysis aimed to evaluate the impact of Vitamin B2 supplementation on the days, duration, frequency, and pain score of the migraine attack.
The PRISMA guideline was used for the studying process. Five electronic databases, PubMed, Embase, Cochrane, CINAHL, and CEPS were searched from 1990 to March 2019. The search terms were Vitamin B2, migraine, and prophylactic. A meta-analysis was performed using Comprehensive Meta-Analysis (CMA) version.
Nine articles were included in systemic review and finally meta-analysis. Eight randomized controlled trials and one controlled clinical trial with 673 subjects were analyzed using meta-analysis. Vitamin B2 supplementation significantly decreased migraine days (
= .005,
= 89%), duration (
= .003,
= 0), frequency (
= .001,
= 65%), and pain score (
= .015,
= 84%).
A pooled analysis of available randomized controlled clinical trials demonstrated that Vitamin B2 400 mg/day for three months supplementation had significant effect on days, duration, frequency, and pain score of migraine attacks.

Although bystanders who confront harassers and support targets of harassment may promote inclusivity, the use of humor to express antigay harassment may inhibit prosocial bystander intervention. Non-LGBTQ+ undergraduates (N = 326) were randomly assigned to respond to a scenario in which a male peer disparaged another peer with antigay comments involving either the presence or absence of humor. Results showed that bystanders reported less intent to intervene in the presence of humor than in its absence. Bystander gender moderated perceptions of humorous harassing speech but not intent to intervene. In the presence of humor, men but not women perceived antigay harassment as more amusing; they also perceived the harassing peer more favorably. To promote ally behavior, bystander education may explicitly address critical thinking about the functions and effects of disparaging humor.The COVID-19 pandemic created an opportunity to incorporate nurse-led virtual home care visits into heart failure patients' plan of care. As a supplemental nurse visit to traditional in-person home visits, the Virtual Nurse Visit (VNV) service was deployed using Zoom teleconferencing technology enabling telehealth nurses to remotely communicate, assess, and educate their patients. This mixed methods study explored heart failure patients' abilities, experience, and satisfaction to use and adopt a virtual nurse visit. Sociodemographic, semi-structured interview questions, and the System Usability Scale data were collected. Thirty-four participants completed the study. Over half of participants perceived the VNV usable and four qualitative themes emerged perceived safety during COVID-19, preferences for care delivery, user experiences and challenges, and satisfaction with the VNV service. Findings from this study builds the science around telehealth that will inform future studies examining this type of nurse-led virtual visit and subsequent patient outcomes.
