AbstractThe paper reports the synthesis of Zinc Oxide (ZnO) nano particles in pure and Gadolinium (Gd) doped forms via hydrothermal method. The annealing temperatures for the samples were fixed at 600 °C and 800 °C. The ZnO nano particles in their pure and Gd doped forms were incorporated in the Polystyrene matrix and drawn to microfibers by the method of electrospinning (ES). The structural studies were carried out using Scanning Electron Microscopy-Energy Dispersive x-ray Spectroscopy (SEM-EDS), Transmission Electron Microscopy (TEM), x-ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). The optical absorption and emission properties were studied using UV-Visible Absorption spectroscopy and Fluorescence Spectroscopy. The SEM-EDS confirmed the presence of Gd in ZnO. In the ZnO structures more crystallinity was observed for samples annealed at 800 °C. The particle size of the prepared nano particles were found to vary from 77 nm to 194 nm. The optical absorption behavior of the samples was explained using Brus effective mass model. The fluorescence emission spectrum of the nano particle samples were analyzed and found that the emission properties depend on their particle size. The XRD, UV-Visible and Fluorescence analysis of fibers confirmed the presence of ZnO and Gd doped ZnO nano particles in the polystyrene fibers. The distinct optical absorption and emission behavior of the microfibers were greatly affected due to the presence of nano particles in the polymer matrix.

Abstract
Lykhmanivka (Inhulets) iron ore district takes the southernmost position in the Kryvyi Rih iron ore basin. In the north, it is bordered by a series of sublatitudinal faults with the Southern Iron Ore District of Kryvbas. The productive strata of the area are Lykhmanivka iron ore pay streak, in the southern part of which the Inhulets deposit of magnetite quartzites is located in the zone of closing of Lykhmanivka syncline. However, in addition to them in the area, there are more than 20 types of other minerals, which are mined by-products and can be successfully used in the national economy. Syngenetic (sedimentation, diagenesis, dynamothermal metamorphism) and epigenetic processes (tectogenesis, metasomatism, hydrothermal processes, hypergenesis), which occurred during the formation of iron ore and host strata area have contributed to the formation of several minerals and rocks, which can be considered as associated complex useful minerals. The relevance of the work is due to the need for detailed research of the localization, formation conditions, directions of use of metallic and nonmetallic minerals of the area, the geological justification for their priority varieties. As a result of these studies, systematization of minerals of the area has been developed, their priority varieties have been identified. Their involvement in mining and processing significantly expands the spectrum of alternative ways of use of minerals and rocks of iron-banded formation, which will contribute to a significant addition to the mineral resource base as in Kryvyi Rih iron ore basin, and in Ukraine as a whole.

Published: July 2022

Abstract
The chemical and energy industries are one of the most powerful generators of solid industrial waste. Such enterprises have water treatment plants. The result of the water treatment process is the formation of a water treatment sludge. The sludge composition includes carbonates and hydroxides of calcium, magnesium, iron, aluminum, and coagulated natural organic materials. A significant amount of waste in the form of fly ash and fuel slag is generated in the process of burning coal at power plants. Such wastes are usually classified as “low-risk”. Nevertheless, when wastes are stored in the storage, they create environmental and economic problems. Large areas of land are alienated for storage. Dust emissions and filtration losses are observed in the process of waste storage. The wastes impact of the Luhansk region enterprises on the environment has been studied. Waste storage facilities are located on the left bank of the Seversky Donets River in the zone of Dnieper-Donetsk structure articulation and the Voronezh anteclise. Features of the territory geological environment are explained by the presence of geological disturbances, loamy-sandy and carbonate rocks, manifestations of carbonate karst. The wastes degrade the quality of surface and ground waters used for water supply in the region.
Awareness of antibiotic resistance for the environmental health and sustainable development: a cross-sectional study
Authors: Galaburda M , Yustyniuk V , Kuzminska O , Galat M , Correa M 
Published: July 2022

Abstract
Antimicrobial resistance (AMR) is a significant threat for global health and has been recognized as a threat to the world’s sustainable development affecting several sustainable development goals (SDG). Uncontrolled and unjustified use of antimicrobial drugs in both agriculture and medicine, leads to the emergence of new strains of microorganisms resistant to antibiotics that can be distributed through the environment and poses both direct and indirect threat to public and environmental health. The systematic literature reviews and cross-sectional study to assess the awareness and attitude to antimicrobial resistance among veterinary and medical students of Ukrainian universities demonstrates the relationship between the antibiotic resistance issue and its influence on environmental health as the important determinant of global health and the Sustainable Development Goals. Both medical and veterinary students acknowledged the antimicrobial resistance to a certain extent. However, differences among the responses of target groups demonstrate that medical students are better trained on antimicrobial prescriptions to humans and more familiar with the protocols of treatment of different diseases of humans. Findings can be used for the development of educational activities aiming to improve knowledge on antimicrobial use, particularly in the framework of One Health approach.

Abstract
The post-industrial stage of development determined a significant reduction of the importance of industrial production, which led to restructuring the economy. An active process of revaluation has begun – reassessing the value of industrial heritage and finding options for its further use. Kryvyi Rih is the most powerful industrial center of Ukraine and despite the fact that the industry is in an active stage of operation, the issue of diversification of the city’s economy and further transformation of industrial facilities is raised in a timely manner. The tasks of this research are theoretical analysis of the concept of revitalization”, the essence of this process, the study of practical experience of revitalization in Ukraine and abroad, the result of which should be an analysis of prospects for the implementation of this process in the industrial heritage of Kryvyi Rih. The analysis of the possibilities of Kryvyi Rih industrial heritage revaluation was carried out through the prism of an interdisciplinary approach based on research in architecture, ecology, economics, geography and culturology. Disclosure of this issue took place at two levels of research: theoretical and empirical. Theoretical research was based on the use of general scientific systems approach, analysis and synthesis, structural-functional analysis, comparative analysis, modeling methods, design, SWOT and PEST-analyzes of the probable effectiveness of revitalization in Kryvyi Rih. Empirical research was expeditionary methods, observations, the method of field visual inspections. The study has structured the concept of “revitalization”, revealed promising areas of industrial facilities revitalization. The world tendencies and the best national examples of transformation of industrial territories into various innovation spaces have been analyzed. An assessment of the potential of the city’s various objects in terms of revitalization opportunities has been given. Conceptual models of creation of the Industrial Culture Park “SHAKHTA” on the place of the preserved mine “Artem-2”, and also industrial and landscape park on the place of Burshchitsky dump have been prepared, futuristic possibilities of their use in the tourist activity have been allocated. Intensification of efforts of specialists in various related fields to ensure the sustainable development of the urban environment of old industrial areas is the key to a qualitative revival of industrial spaces, harmonization and ecological optimisation of the former industrial environment, solving a number of socio-economic problems.

Published: July 2022

Abstract
Aqueous zinc-ion batteries (ZIBs) are considered as a promising energy storage system for large-scale energy storage in terms of their high safety and low cost. In recent years, two-dimensional (2D) materials have been widely applied in designing the electrodes of aqueous ZIBs since they generally possess the characteristics of large surface areas, plentiful ion transport channels and abundant active sites. Thus, they can not only act as the active materials and conductive additives in cathodes, but also be employed as the artificial interface layers or conductive substrates of Zn anodes. In this review, the issues of aqueous ZIBs and the unique properties of 2D materials are discussed briefly. Then we highlight the recent advances of the applications of various 2D materials, mainly including transition metal oxides, transition metal dichalcogenide, graphene and MXenes, in the design of the cathodes and anodes of aqueous ZIBs. Finally, we present the challenges and perspectives of 2D materials in aqueous ZIBs.
Strike or ball? Batters know it better: an fMRI study of action anticipation in baseball players
Authors: Chen Yin-Hua , Chang Chih-Yen , Huang Shih-Kuei 
Published: July 2022

AbstractTo assess whether the brain processes of action anticipation are modulated differently by perceptual and motor experiences, baseball batters, pitchers, and non-players were asked to predict the fate of pitching actions (strike or ball) while undergoing functional magnetic resonance imaging. Results showed both batters (perceptual experts of pitching action) and pitchers (motor experts) were more accurate than non-players. Furthermore, batters demonstrated higher perceptual sensitivity in discriminating strikes than non-players. All groups engaged the action observation network, putamen, and cerebellum during anticipation, while pitchers showed higher activity than non-players in the left premotor cortex, which has been implicated in the internal simulation of observed action. Only batters exhibited differences in strike versus ball pitches in their left ventral extrastriate cortex, which might be associated with the processing of relevant visual information conveyed by the observed pitcher’s movement kinematics and pitch trajectory. Moreover, all groups showed higher activity selectively in the striatum, thalamus, sensorimotor cortices, and cerebellum during correct predictions than during incorrect ones, with most widespread activation in batters, reinforcing the greater involvement of the sensorimotor system in perceptual experience. Our findings demonstrate that perceptual experience might enhance action anticipation ability to a greater extent than motor experience, with overlapping but specific neural underpinnings.

Abstract

Background
Maternal tenofovir disoproxil fumarate (TDF) therapy during late pregnancy can reduce mother-to-infant transmission of hepatitis B virus (HBV). We investigated HBV mutations associated with maternal TDF therapy and their role in infant immunonophylaxis failure (IPF).

Methods
Serum samples from untreated (n = 89) and TDF-treated (n = 68), highly viremic, chronically infected mothers and their infants were analyzed for HBV DNA by nested polymerase chain reaction (PCR) and direct sequencing.

Results
At delivery, compared with untreated mothers, TDF-treated mothers had a lower HBV DNA titer and a higher frequency of basal core promoter (BCP) gene mutations, but they had similar frequencies in pre-S/S and pre-core/core mutations. The 14 mothers harboring surface “a” determinant mutants did not transmit the mutants to their immunized infants. Such mutants were found in 3 of 13 IPF infants; the 13 mothers had wild-type hepatitis B surface antigen (HBsAg). In univariable analysis, maternal HBV DNA titer (odds ratio [OR]: 1.54; 95% confidence intervals [CI]: 1.02–2.33; P = .039), genotype C (OR: 4.18; 95% CI: 1.28–13.62; P = .018) and pre-S1 wild-type sequence (OR: 6.33; 95% CI: 1.85–21.68; P = .003) at delivery were associated with infant IPF. Multivariable analyses showed that maternal genotype C (OR: 3.71; 95% CI: 1.11–12.36; P = .033) and pre-S1 wild-type (OR: 6.34; 95% CI: 1.79–22.44; P = .004) were associated with infant IPF independently of maternal viremia.

Conclusions
Along with high maternal HBV DNA titer at delivery, maternal genotype C and pre-S1 wild-type sequence were potential risk factors for infant IPF, although BCP mutations were not. The offspring of pregnant women harboring “a” determinant mutants as major strains seemed to be protected by immunoprophylaxis.

Abstract
Little is known about the risk of multisystem inflammatory syndrome in children (MIS-C) with different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. In southeast England, MIS-C rates per confirmed SARS-CoV-2 infections in children aged 0–16 years were 56% lower (rate ratio [RR], 0.34 [95% confidence interval {CI}, .23–.50]) during prevaccine Delta, 66% lower (RR, 0.44 [95% CI, .28–.69]) during postvaccine Delta, and 95% lower (RR, 0.05 [95% CI, .02–.10]) during the Omicron period.

Published: July 2022

Abstract
As one of the highest energy consumer organs in the body, the heart requires tremendous amount of adenosine triphosphate (ATP) to maintain its continuous mechanical work. Fatty acids, glucose, and ketone bodies are the primary fuel source of the heart to generate ATP with perturbations in ATP generation possibly leading to contractile dysfunction. Cardiac metabolic imaging with magnetic resonance imaging (MRI) plays a crucial role in understanding the dynamic metabolic changes occurring in the failing heart, where the cardiac metabolism is deranged. Also, targeting and quantifying metabolic changes in vivo noninvasively is a promising approach to facilitate diagnosis, determine prognosis, and evaluate therapeutic response. Here, we summarize novel MRI techniques used for detailed investigation of cardiac metabolism in heart failure including magnetic resonance spectroscopy (MRS), hyperpolarized MRS, and chemical exchange saturation transfer based on evidence from preclinical and clinical studies and to discuss the potential clinical application in heart failure.
Chronic rheumatic heart disease with recrudescence of acute rheumatic fever on histology: a case report
Authors: Mutithu Daniel W , Roberts Riyaadh , Manganyi Rodgers , Ntusi Ntobeko A B 
Published: July 2022

Abstract

Background
Rheumatic heart disease (RHD) is endemic in sub-Saharan Africa where it is the leading cause of cardiovascular mortality in the young. Rheumatic heart disease results from recurrent episodes of acute rheumatic fever (ARF), which are often difficult to diagnose clinically. Acute rheumatic fever may be diagnosed based on the revised Jones Criteria 2015 for the diagnosis of ARF. Histologically, acute rheumatic valvulitis manifests with active inflammation characterized by lymphocytic infiltration, Aschoff bodies, and Anitschkow cells. Chronic rheumatic valvulitis is associated with neovascularization, and/or dystrophic calcification. The combination of histological features of both ARF and chronic RHD is a rare finding.

Case summary
Here we report on a case of a 59-year-old woman with mixed aortic and mitral valve disease of probable rheumatic aetiology (elevated C-reactive protein and prolonged PR interval) and with histological evidence of lymphocytic infiltration, Aschoff bodies, and fibrinoid necrosis admixed with features of chronic RHD.

Discussion
Cases of chronic RHD admixed with ARF are very rare; however, they should be considered in regions with a high prevalence of RHDs.
Intersectoral violence prevention: the potential of public health–criminal justice partnerships
Authors: Gebo Erika 
Published: July 2022

Abstract
Building successful intersectoral partnerships to address health is critical to reaching health promotion goals. With the confluence of the COVID-19 pandemic, the increase in violence during the pandemic and the heightened demand for racial justice resulting from police killings of people of color, particularly young, black males, intersectoral public health–criminal justice partnerships must be more thoroughly examined. Violence prevention is both a public health and criminal justice issue, with public health systems emphasizing primary prevention and criminal justice systems addressing violence prevention at secondary and tertiary levels. Public health–criminal justice collaborations can provide an opportunity to seize upon unrealized violence reduction goals across the spectrum of prevention. At the same time, issues remain that are at odds across field boundaries as exemplified through community violence prevention. While there have been successful examples of such collaborations, past public health–criminal justice partnerships also demonstrate the challenges of working together. These challenges have yet to be systematically described and rooted in the larger literature on partnerships. In this paper, collaborative challenges are enumerated and evidence-informed strategies to overcome those barriers to achieve violence reduction goals are identified as a way to ground further intersectoral partnership work between public health and criminal justice.
Culturally appropriate health solutions: Aboriginal men ‘thriving’ through activities in Men’s Sheds/groups
Authors: Cavanagh Jillian , Pariona-Cabrera Patricia , Bartram Timothy 
Published: July 2022

Abstract
This study examines social determinants impacting the health and wellbeing of Aboriginal and Torres Strait Islander men in Australia. Social determinants prevent many men from thriving in community environments which also impacts on their social, work and family lives. We examine the impact on men’s health and identify how men who participate in Men’s Sheds/groups engage in learning about health interventions. Our study extends the work of Percival et al. and their Indigenous health promotion model. A qualitative case study approach conducted ‘gatherings’ and ‘yarning circles’ (focus groups) with men from urban, regional and remote areas of the country. We argue that men’s groups can serve as a central intervention to support men to build their confidence to learn about health and wellbeing and how to thrive through activities in community life. Findings support health interventions delivered through training and mentoring around various health and other services, healthy eating, sport and fathering programmes (to name a few) to enhance awareness and men’s vitality for learning. There are implications for our healthcare system to better understand the conditions of Aboriginal men’s health and support these vulnerable groups. Our study proposes men’s groups as culturally safe environments to promote and deliver central health promotion interventions that support men to thrive in all facets of their lives.
Is US grand strategy dead? The political foundations of deep engagement after Donald Trump
Authors: Friedman Jeffrey A 
Published: July 2022

Abstract
International Relations scholars frequently warn that the American political system has become too fractured to sustain a coherent grand strategy. This perception generally rests on two premises: that President Donald Trump led an unprecedented assault on established principles of US foreign policy, and that Democrats and Republicans have become so polarized that they can no longer agree on a common vision for global leadership. By contrast, this article argues that the grand strategy of deep engagement retains robust bipartisan support. Even though President Trump rejected more expansive conceptions of liberal internationalism, his behaviour was largely consistent with deep engagement's principles. Moreover, when Trump departed from deep engagement—as with questioning the US commitment to NATO—his actions did not reflect voters' policy preferences. In fact, polling data indicate that public support for deep engagement is at least as strong today as it has been at any other point since the end of the Cold War. Altogether, the article thus demonstrates that the grand strategy of deep engagement is less embattled, and more politically viable, than the conventional wisdom suggests.
