    Tuned cylindrical radial mode ultrasonic horns offer advantages over ultrasonic probes in the design of flow-through devices for bacterial inactivation. This study presents a comparison of the effectiveness of a radial horn and probe in the inactivation of Escherichia coli K12. The radial horn is designed using finite element analysis and the predicted modal parameters are validated using experimental modal analysis. A validated finite element model of the probe is also presented. Visual studies of the cavitation fields produced by the radial horn and probe are carried out using luminol and also backlighting to demonstrate the advantages of radial horns in producing a more focused cavitation field with widely dispersed streamers. Microbiological studies show that, for the same power density, better inactivation of E. coli K12 is achieved using the radial horn and, also, the radial horn offers greater achievable power density resulting in further improvements in bacterial inactivation. The radial horn is shown to be more effective than the probe device and offers opportunities to design in-line flow-through devices for processing applications

    We have imaged the extremely high-velocity outflowing gas in CO (2-1) and (3-2) associated with the shell-like ultracompact HII region G5.89-0.39 at a resolution of ~3" (corresponding to ~4000 AU) with the Submillimeter Array. The integrated high-velocity (>45 km/s) CO emission reveals at least three blueshifted lobes and two redshifted lobes. These lobes belong to two outflows, one oriented N-S, the other NW-SE. The NW-SE outflow is likely identical to the previously detected Br_gamma outflow. Furthermore, these outflow lobes all clearly show a Hubble-like kinematic structure. For the first time, we estimate the temperature of the outflowing gas as a function of velocity with the large velocity gradient calculations. Our results reveal a clear increasing trend of temperature with gas velocity. The observational features of the extremely high-velocity gas associated with G5.89-0.39 qualitatively favor the jet-driven bow shock model.Comment: 14 pages, 4 figures, accepted for publication in ApJ Letter

    The title compound, [Ni(C8H10F3O2)2(CH4O)1.55(H2O)0.45][Ni(C8H10F3O2)2(CH4O)0.51(H2O)1.49], is an octa­hedral nickel(II) complex with two acetyl­acetonate-like 1,1,1-trifluoro-5,5-dimethyl­hexane-2,4-dionate ligands. The two chelating ligands are in cis positions with respect to each other and the remaining two adjacent coordination sites are taken up by water and methanol donor mol­ecules. In both crystallographically independent mol­ecules, each donor site shows disorder of methanol and water with occupancies of 0.51 (1) and 0.55 (1) in favor of methanol. The remaining two donor sites are not disordered and are water for the first and methanol for the second independent mol­ecule. Rotational disorder is observed for one of the tert-butyl groups, the occupancy rate for the major component here is 0.687 (9). O—H⋯O hydrogen bonds connect the two independent mol­ecules with each other and, across a crystallographic inversion center, they are combined with two neighboring mol­ecules to form a centrosymmetric hydrogen-bonded tetra­mer

    Breaking the habit: a qualitative exploration of barriers and facilitators to smoking cessation in people with enduring mental health problems

    BACKGROUND: Smoking in people with mental health problems (MHPs) is an important public health concern as rates are two to three times higher than in the general population. While a strong evidence base exists to encourage and support smoking cessation in the wider population, there is limited evidence to guide the tailoring of interventions for people with MHPs, including minimal understanding of their needs. This paper presents findings from theoretically-driven formative research which explored the barriers and facilitators to smoking cessation in people with MHPs. The aim, guided by the MRC Framework for the development and evaluation of complex interventions, was to gather evidence to inform the design and content of smoking cessation interventions for this client group. METHODS: Following a review of the empirical and theoretical literature, and taking a critical realist perspective, a qualitative approach was used to gather data from key stakeholders, including people with enduring MHPs (n = 27) and professionals who have regular contact with this client group (n = 54). RESULTS: There was a strong social norm for smoking in participants with MHPs and most were heavily addicted to nicotine. They acknowledged that their physical health would improve if they stopped smoking and their disposable income would increase; however, more important was the expectation that, if they attempted to stop smoking, their anxiety levels would increase, they would lose an important coping resource, they would have given up something they found pleasurable and, most importantly, their mental health would deteriorate. Barriers to smoking cessation therefore outweighed potential facilitators and, as a consequence, impacted negatively on levels of motivation and self-efficacy. The potential for professionals to encourage cessation attempts was apparent; however, they often failed to raise the issue of smoking/cessation as they believed it would damage their relationship with clients. The professionals’ own smoking status also appeared to influence their health promoting role. CONCLUSIONS: Many opportunities to encourage and support smoking cessation in people with MHPs are currently missed. The increased understanding provided by our study findings and literature review have been used to shape recommendations for the content of tailored smoking cessation interventions for this client group

    Research Benefits for Scholarly Authors Being Published on a Public Forum

    The previous construct of research was focused on social media platforms as a benefactor in broadcasting towards a global audience with non-academic professions. Following along the same ideology, this research directs the attention to a pertained audience in academic profession. •Embry-Riddle is the host of Scholarly Commons which collects the research of authors (faculty members), and assists in developing a digital portfolio. This portfolio creates metric measurements on a dashboard to indicate where downloads are occurring, and aids in providing current information pertaining to the authors’ publication. •In this case, the publication of the National Airline Quality Rating (AQR) (https://airlinequalityrating.com/) in Scholarly Commons focuses on locating members that are attracted to the quantitative research on airline performance

    Leveraging the Dissemination of Scholarly Works

    The objective of this research was to analyze the marketing and economic outcomes and benefits from the dissemination of the data from the Airline Quality Rating (AQR) (http://airlinequalityrating.com) over the past 27 years, including the newer distributive avenues such as social media and open access venues online. Industry standards are set by the AQR, providing consumers and industry watchers objective performance-based data to compare performance quality among different U.S. airlines. The AQR weighted average formula highlights criteria including baggage handling, customer complaints, denied boarding and on-time arrivals. The scholarly publication of the AQR was first released in 1991; the authors were interviewed on Good Morning America, gaining national media attention for the authors as well as their university. The annual media release of this report grew in reputation over the first three years to a national media event as a valid rating/ranking of the major airlines’ quality; this was validated by an advertising value of over two million dollars. In 2016, the release of the AQR report reached over 1.2 billion people globally, with an advertising and publicity value of twelve million dollars. Today, faculty members can and should utilize the newer distributive platforms for dissemination of their research and scholarly works; some examples of these avenues include: (1) research and scholarly publications being uploaded to Google Scholar for scholarly as well as general public use, (2) taking advantage of social media’s global market, (3) utilizing media venues, including media releases, (4) using online open-access repositories for scholarship submissions. The dissemination of data from the AQR is just one example of the limitless topics that could be applied to other scholarship efforts, benefitting faculty members and their associated universities by effectively leveraging the distribution of their research and associated publications beyond only being published as an obscure journal article

    The research method for this project – examining the dissemination of research artifacts through social media as well as the impact social media can have on scholarly research – originated with Dr. Brent Bowen of Embry-Riddle Aeronautical University at the Prescott, Arizona campus and Dr. Dean E. Headley of Wichita State University. Drs. Bowen and Headley introduced the Airline Quality Rating (AQR) in early 1991 as an objective method for comparing and scoring airline performance in areas deemed to be important for consumers. Scores are calculated by defining 15-elements in four major areas, focusing on airline performance and the significance the factors to consumers of air travel in a given calendar year. The report is a summary and evaluation of month-by-month ratings for U.S. airlines, based on domestic performance data which these companies are required to publish. The general case study focus of this research is the AQR as it relates to the news of the AQR’s release as disseminated through social media platforms, the subsequent utilization of and references to the research by social media users, and the global reach of social media. We will examine social media metrics, based on traditional news releases. These news releases, when amplified by social media platforms, assist in broadening the viewership and the utilization of research. The AQR’s Visibility Reports evaluate four aspects of online traffic - Total Pickup, Traffic flow, Audience, and Engagement. We will discuss how the Airline Quality Rating has helped to facilitate a worldwide discussion on U.S. airlines and domestic air travel within the U.S

    The Hot and Clumpy Molecular Cocoon Surrounding the Ultracompact HII Region G5.89-0.39

    We present observations of CH3CN (12-11) emission at a resolution of 2" toward the shell-like ultracompact HII region G5.89-0.39 with the Submillimeter Array. The integrated CH3CN emission reveals dense and hot molecular cocoon in the periphery of the HII region G5.89-0.39, with a CH3CN deficient region roughly centered at G5.89-0.39. By analyzing the CH3CN emission using population diagram analysis, we find, for the first time, a decreasing temperature structure from 150 to 40 K with the projected distance from Feldt's star, which is thought to be responsible for powering the HII region. Our results further indicate that the majority of the heating energy in the observed dense gas is supplied by the Feldt's star. From the derived CH3CN column density profile, we conclude that the dense gas is not uniformly-distributed but centrally-concentrated, with a power-law exponent of 5.5 for r < 8000 AU, and 2.0 for 8000 AU < r < 20000 AU, where r is the distance to Feldt's star. The estimated large power index of 5.5 can be attributed to an enhancement of CH3CN abundance in the close vicinity of Feldt's star.Comment: accepted for publication in The Astrophysical Journal Letter
