Published: February 2023

Fluoride is a toxic substance that can cause adverse effects on human health such as dental and skeletal fluorosis. Therefore, the objective of this study was to investigate the adsorption potential of fluoride from aqueous solution using eggshell pretreated with plasma technology and compare to untreated eggshell. The batch adsorption experiments of fluoride from aqueous solution using pretreated eggshell and untreated eggshell were carried out to compare their performances on fluoride removal efficiency, adsorption capacity and isotherm. The effects of adsorption factors of contact time (5 - 360 min), adsorbent dosage (10 - 35 g/L) and particle size of adsorbent (mesh sieve no.12 - 20 or 0.85 - 1.70 mm sieve opening) were studied. The results showed that with the initial fluoride concentration of 10 mg/L, the optimum condition for the adsorption of fluoride from aqueous solution was obtained with pretreated eggshell at contact time of 180 min, adsorbent dosage of 25 g/L and adsorbent size of Sieve no.16 (≤1.18 mm in diameter). With this optimum condition, the maximum fluoride removal efficiency increased from 59.88 % with untreated eggshell to 90.34 %, which was due to an increase in adsorption sites after surface modification process of eggshell. Moreover, the results clearly showed that adsorption isotherm was fitted by Langmuir model, which indicate a monolayered adsorption. The maximum adsorption capacity was 0.341 mg/g for pretreated eggshell, while this was 0.202 mg/g for untreated eggshell. This study showed that eggshell pretreated with plasma technology has potential for the application of the adsorption of fluoride from aqueous solution in the future and needs further investigation on the continuous adsorption column.
HIGHLIGHTS

Eggshell pretreated with plasma technology (EPPT) was applied for fluoride removal
Effects of contact time, adsorbent dosage and size were examined by batch method
Maximum fluoride (F) removal efficiency was 90.34 % with EPPT at optimum condition
F adsorption on EPPT fitted Langmuir isotherm with maximum capacity of 0.341 mg/g

GRAPHICAL ABSTRACT
Development of methods for assessing the quality of snail meat
Authors: Danilova Iryna , Danilova Tetiana
Published: February 2023

The meat of edible snails is considered a delicacy and is part of Ukraine's food exports, but there are no regulations or legislation on its quality. The purpose of this work was to develop methods for determining the degree of freshness of snail meat by the content of ammonia and ammonium salts with Nessler's reagent, peroxidase in meat with copper sulfate solution, and processing a smear-print from meat with a fluorescent dye and to determine the quality of meat by the number of green pixels. During the research, first of all, it was determined the organoleptic characteristics of shellfish meat, which reflect their freshness. Next, research was performed to determine the enzymes and ammonia that are produced during meat storage. The following reagents were used: copper sulfate solution, Nessler's reagent, and fluorescent dye – acridine orange. The equipment used for these reactions was used, namely: a KFK-2-UHL 4.2 photometer and an SMT fluorescence microscope with a working current of 2.5 A. Thus, schemes for establishing reactions for determining the degree of freshness of snail meat were developed and tested: biochemical, photometric, and immunofluorescence methods. The stability of the indicators for determining the degree of freshness was established. It is analysed that the data presented relate only to the research on snail meat. Utility model patents have been granted for each method. The proposed methods for assessing the quality of snail meat are effective, technologically simple and fast, have high reliability of the results obtained and can be used in the work of research and experimental, production and regional laboratories of veterinary medicine

Why the delay in recognizing terrestrial obligate cave species in the tropics?
Authors: Howarth Francis
Published: February 2023

“Nothing could possibly live there!” They believed. Indeed, until recently, few specialized cave- adapted animals were known from volcanic, tropical, or oceanic island caves, and plausible theories had been put forward to explain their absence. But assume nothing in science! One must illuminate, explore, and survey habitats before declaring them barren. Our understanding of cave biology changed dramatically about 50 years ago following the serendipitous discovery of cave-adapted terrestrial arthropods in Brazil and on the young oceanic islands of the Galápagos and Hawai‘i. These discoveries and subsequent studies on the evolutionary ecology of cave animals have revealed a remarkable hidden fauna and created new sub- disciplines within biospeleology. Biological surveys of caves in other regions have continued to expand our understanding of the evolution, adaptation, and ecology of the subterranean biome. We now predict that, rather than being relicts trapped in caves by changing climate, many animals actively colonized caves and adapted to exploit food resources wherever there were suitable subterranean voids. The physical environment in caves can be determined with great precision because the habitat is buffered by rock. Furthermore, the bizarre adaptations displayed by obligatory cave animals are similar across many taxonomic groups. These two characteristics make caves nearly ideal natural laboratories for studying evolution and ecology. However, to the untrained researcher, caves can appear hostile and dangerous, and in fact, fieldwork in caves requires a unique marriage of athletic ability and science. In other words, cave research is exciting! In this contribution, I describe the exploration, discovery, and research in tropical caves and describe the factors that delayed the recognition of a significant tropical cave fauna.
Learning from disaster: A natural experiment exploring disaster preparedness before and during the COVID-19 pandemic by houses of worship
Authors: Pudlo, PhD Jason M.
Published: February 2023

This study illuminates how congregations adapted to an unfolding crisis in real-time and reveals areas of organizational learning and vulnerability. The driving question of this study asks “how has congregational disaster readiness changed during COVID-19?” From this, three measurable corollary questions emerge. First, how has experience during the pandemic changed risk assessment and planning? Second, how has disaster networking changed due to pandemic experiences? Third, did pandemic experience lead to a change in collaboration activities and actions? A natural experiment research design is used to answer these questions. Data collected from survey responses from 50 congregational leaders in 2020 are compared to their baseline responses and interviews as part of a more extensive study from 2019 of over 300 leaders. Descriptive analysis is used to evaluate how congregational leaders changed their risk assessment, disaster planning, disaster networking, and collaboration activities from 2019 to 2020. Open-ended questions provide qualitative context for the survey responses. Initial results support two themes for scholars and emergency managers: learning is immediate, and network maintenance matters. First, while awareness of pandemics has grown, congregational leaders narrowly applied the lessons they learned to temporally and spatially immediate hazards. Second, congregational networking and collaboration became more insular and local during the pandemic response. These results could have substantial implications for community resilience, especially given the role congregations and similar organizations play in community disaster resiliency.
Post-pandemic tourism strategies: A case of Himachal Pradesh
Authors: Barbhuiya, PhD Mahfuzuar Rahman
Published: February 2023

Tourism has always been a vulnerable industry. Minimal disturbances can halt or even destroy tourism and its associated economy. There is no dearth of research on vulnerability and resilience of the tourism industry for various tourism destinations,, and on post-disaster studies, but mainly these were limited to a city or tourist destination and focused on the destination image recovery. The primary purpose of this study is to identify different tourism stages and the local community’s issues and desires associated with each stage and to propose strategies that can be used during and after the COVID-19 pandemic. The district-wise monthly domestic and foreign tourist arrival data from 2008 to 2018 for Himachal Pradesh (HP) were observed. The observations reveal that HP experiences overtourism, balanced tourism, and undertourism. Two hundred seven telephonic interviews were conducted with different stakeholders such as tourism department officers, urban planners, hotel owners and managers, environmentalists, and state residents. Research themes were identified based on the interview responses, and these themes were further validated using a review of newspaper reports and court and local administration order. This study identified nine broad problems and patterns associated with tourism and proposes 17 sustainable tourism strategies that the post-COVID-19 crisis can follow. The proposed strategies give special attention to confidence-building of tourist and residents, image building of the location, and increasing tourism number sustainably and tourism earning of the state. This study investigates problems and suggests sustainable strategies for a state in India for the first time and may be used for policy decision and regional sustainable tourism development plan.
Intention to vaccinate against COVID-19 and potential outreach strategies for a residential research university in Northeastern Ohio
Authors: Pellegrino, PhD Jeffrey L. , Miller, MS Brian , Krob, DHEd Jamillee , Darago Travis
Published: February 2023

Introduction: A university’s understanding of student, faculty, and staff members’ intention to vaccinate against COVID-19 has been vital in returning safely to in-person education, research, and engagement with communities and professions. We employed a novel survey to describe intentions across subpopulations of one campus and consider key issues in their rationales for intentions and hesitancies. Materials and methods: 1,077 surveys based on Theory of Planned Behavior were completed from randomly selected pools of undergraduate students, graduate students, part-time faculty, full-time faculty, and staff. Chi-Squared Automated Interaction Detection algorithm analysis provided paths for evaluation. Results and discussion: 83 percent of respondents said they would receive the vaccine at their first opportunity, while 5 percent said they would never get the vaccine; the remaining 12 percent wanted more evidence before getting the vaccine. Findings included negative health perceptions of the vaccine, misinformation on the process, as well as negative rhetorical responses differentiated between political partisanship and membership within the campus community, eg, faculty, staff, or student.Implications: Universities seeking to raise campus vaccination rates should concentrate limited resources on the largest populations with the most opportunity to vaccinate. In this study, newer students, with conservative political views, represented a population of opportunity. Their formative beliefs may be influenced by messaging and in collaboration with students’ personal physician and/or friend groups. A theory-based approach leads to focused efforts for safer campuses and resumption/continuation of face-to-face interactions for students, faculty, and staff.

Background: Terrorist attacks and natural disasters such as Hurricanes Katrina and Harvey have increased focus on disaster preparedness planning. Despite the attention on planning, many studies have found that hospitals in the United States are underprepared to manage extended disasters appropriately and the surge in patient volume it might bring. Aim: This study aims to profile and examine the availability of hospital capacity specifically related to COVID-19 patients, such as emergency department (ED) beds, intensive care unit (ICU) beds, temporary space setup, and ventilators.Method: A cross-sectional retrospective study design was used to examine secondary data from the 2020 American Hospital Association (AHA) Annual Survey. A series of multivariate logistic analyses were conducted to investigate the strength of association between changes in ED beds, ICU beds, staffed beds, and temporary spaces setup, and the 3,655 hospitals’ characteristics.Results: Our results highlight that the odds of a change in ED beds are 44 percent lower for government hospitals and 54 percent for for-profit hospitals than not-for-profit hospitals. The odds of ED bed change for nonteaching hospitals were 34 percent lower compared to teaching hospitals. Small and medium hospitals have significantly lower odds (75 and 51 percent, respectively) than large hospitals. For ICU bed change, staffed bed change, and temporary spaces setup, the conclusions were consistently significant regarding the impact of hospital ownership, teaching status, and hospital size. However, temporary spaces setup differs by hospital location. The odds of change is significantly lower (OR = 0.71) in urban hospitals compared with rural hospitals, while for ED beds, the odds of change is considerably higher (OR = 1.57) in urban hospitals compared to rural hospitals.Conclusion: There is a need for policymakers to consider not only resource limitations that were created from supply line disruptions during the COVID- 19 pandemic but also a more global assessment of the adequacy of funding and support for insurance coverage, hospital finance, and how hospitals meet the needs of the populations they serve.

Introduction: It is vital that households are prepared for a natural disaster to help mitigate potential negative impacts. Our goal was to characterize United States household preparedness on a national level to guide next steps to better prepare for and respond to disasters during the COVID-19 pandemic. Methods: We added 10 questions to the existing Porter Novelli’s ConsumerStyles surveys in fall 2020 (N = 4,548) and spring 2021 (N = 6,455) to examine factors that contribute to overall household preparedness levels.Results: Being married (odds ratio (OR), 1.2), having children in the home (OR, 1.5), and having a household income of $150,000 or more (OR, 1.2) are all associated with increased preparedness levels. Those in the Northeast are least likely to be prepared (OR, 0.8). Persons living in mobile homes, Recreational Vehicles, boats, or vans are half as likely to have preparedness plans compared to those living in single family homes (OR, 0.6).Conclusions: As a nation, there is much work to be done in terms of preparedness to reach performance measure targets of 80 percent. These data can help inform response planning and the updating of communication resources such as websites, fact sheets, and other materials to reach a wide audience of disaster epidemiologists, emergency managers, and the public.
A longitudinal study of Oklahoma City bombing rescue and recovery responders providing qualitative introspections of their experience nearly a quarter century later
Authors: North, MD, MPE, DLFAPA Carol S. , McDonald, LPC Katy , Surís, PhD, ABPP Alina , Hong, PhD Barry A.
Published: February 2023

Background: The 1995 terrorist bombing in Oklahoma City provided a particularly useful research opportunity. It was the most severe incident of terrorism on American soil at the time. Prior research on rescue and recovery workers responding to such events has been largely limited to early post-disaster periods, most focusing on psychopathology such as post-traumatic stress disorder. This incident provided a unique unrealized opportunity to examine long-term psychosocial effects on first responders studied longitudinally over decades after the event, using qualitative methods to yield rich, in-depth observations.Methods: A volunteer sample of 181 volunteer first responders for the Oklahoma City bombing was initially assessed 3 years after the bombing, and 124 (70 percent of those documented to still be alive) participated in longitudinal follow-up interviews an average of 23-24 years after the incident. The follow-up study included open-ended, nondirected qualitative interviews of the workers’ personal disaster narratives.Results: The experience of providing rescue and recovery efforts after the Oklahoma City bombing had lasting effects on these first responders’ personal and professional relationships. It taxed their coping skills, elicited an enduring resilience, and permanently altered their outlook on life. Unlike the directly exposed survivors, these first responders found meaning and affirmation in their professional service, reaffirming their original motivations to be part of a helping profession that in today’s world now requires recovery and rescue work in major terrorist incidents. Even though the work was very gruesome and taxing, more than two decades later, these workers expressed pride in their participation and had no regrets about it.Conclusions: The Oklahoma City bombing experience was life-changing for first responders, setting a standard for those who will follow in their footsteps. Continuing to conduct this line of work in the decades to follow reflected a conviction that their continued service honored both survivors and members of their profession. Despite the positive aspects of their perspectives on their experience, the attention they received to their emotional and psychological processing and recovery was limited, implying the importance of additional development and research on assistance to these needs.

Surveillance is the backbone of any response to an infectious disease outbreak, and comprehensive evaluation of surveillance systems is crucial. However, structured evaluations of surveillance systems during the COVID-19 pandemic are scarce. We conducted a after action review (AAR) of the performance of the COVID-19 surveillance system in Quang Ninh Province, Vietnam, during 2020 using the COVID-19-specific AAR methodology developed by the World Health Organization in combination with guidance from the US Centers for Disease Control and Prevention (CDC). We conducted a stakeholder survey, document reviews, and key informant interviews with staff from Quang Ninh CDC’s COVID-19 surveillance system. The COVID-19 surveillance system was based on the pre-existing surveillance system in the province. The system’s strengths were early preparation for emergency response, strong governance and central coordination, and multidisciplinary collaboration. Stakeholders agreed that the system proved useful and adaptive to the fast-evolving COVID-19 situation but was weakened by overly complex systems, redundant administrative processes, unclear communication channels, and lack of resources. Overall, the surveillance systems in Quang Ninh province proved effective in containing COVID-19 and adaptive in a fast-changing epidemiological context. Several recommendations were made based on identified areas of concern that are of relevance for COVID-19 surveillance systems in Vietnam and similar settings.

Introduction: Fear of COVID-19 may differ for individuals with compromised health and those with unhealthy behaviors, placing them at greater risk. Based on previous analysis of academic medical center faculty and staff, the authors predicted that workers who were smokers/previous smokers would express the greater fear of COVID-19 relative to nonsmokers. Methods: The present study used the Fear of COVID-19 Scale to assess fear among nonsmokers (n = 1,489) and smokers/previous smokers (n = 272) from a larger population of academic medical center members (N = 1,761). This study assessed nonsmokers’ and smokers/previous smokers’ demographic and background variables on Fear of COVID-19 scores. Results: In this academic community, smokers/previous smokers had higher fear of COVID-19 scores than did nonsmokers (p < 0.05). Smokers/previous smokers differed from nonsmokers on three Fear of COVID-19 scale items (most afraid of COVID-19, fear of losing life, and physiological fear of COVID-19). Discussion/conclusions: These results provide a better understanding of how fear of COVID-19 can differ based on one’s smoking status. These findings inform public health smoking cessation efforts aimed at reducing morbidity and mortality, both in response and secondary to COVID-19 exposure.

Published: February 2023

The most disseminated roentgenological measuring methods of scoliotic deformed spine arches in frontal plane - Ferguson, Cobb and Jentschura - are represented. The comparative mathematical analysis of the results of synchronous measurement of 98 scoliotic deformed spine arches using these methods was made. Comparison of the methods and their algorithms was carried out with the devised model of the deformity arch. Groundlessness of the Ferguson and Jentschura methods for using in clinical practice was mathematically proved. The validity and expediency of application of the Cobb`s method of measurement was objectively corroborated, because the essence of this method corresponds to orders of the classical geometry. Exactly the Cobb`s method is recommended to be used in clinical practice as a diagnostic standard of quantitative estimation of scoliotic deformed spine arches parameters in frontal plane.
