A facile and straightforward immersion approach to enhance the hydrophobicity of melamine sponge for efficient cleanup of crude oils and organic solvents
Authors: Chen Jiangwei , Hu Mingyang , Liu Yun 
Published: April 2023

Abstract
The use of biomass-modified hydrophobic materials for cleaning up spilled oils and organic solvents from the environment is currently in high demand. In this study, we developed a simple immersion strategy to modify commercial melamine sponge (MS) using a tetrahydrofuran (THF) extract solution of biomass such as corn stove, pine, and Eucalyptus. This modification process resulted in a highly hydrophobic absorbent with satisfactory superoleophilicity towards various oils (104 g.g-1) and organic solvents (137 g.g-1). The modified MS demonstrated a good oil adsorption capacity with a contact angle of more than 130°. Remarkably, it also exhibited excellent properties of mechanical extrusion, harsh temperature treatment, and recyclability, owing to its three-dimensional high porosity and micro/nano-structure that trap air. Moreover, we found that other biomass extraction solutions such as γ-valerolactone, N, N-dimethylformamide, acetone, methanol, and ethanol could also serve as suitable modification agents to prepare hydrophobic MS through an immersion strategy. The hydrophobicity and stability of the modified MS obtained using this approach were superior to the lignin-modified and DES-extracted lignin-modified MS. Our findings open up new possibilities for the fabrication of modified MS with high hydrophobicity, using a facile, cost-effective, and environmentally-friendly dipping approach for the cleanup of spilled oils and organic solvents.

Abstract

Objective
It is often believed that pregnant women who use illicit substances are more likely to experience psychosocial issues like smoking, depression, and inadequate health care compared to pregnant women who do not. However, the prevalence of these psychosocial issues has rarely been calculated and compared using nationally representative data.
Methods
Important psychosocial issues identified by the American College of Obstetricians and Gynecologists were operationalized using variables in the National Survey on Drug Use and Health. We report weighted prevalence and age-adjusted odds ratios for these issues in pregnant women who did vs. did not report past-month illicit substance use.
Results
Pregnant women (n = 3,657) who reported past-month illicit substance use (6.3%; 95% CI 5.4-7.0) had significantly higher rates of almost all psychosocial issues examined, including past-month cigarette smoking (44.9% vs. 6.5%; age-adjusted odds ratio (AOR) = 7.14 (95% CI 4.98–10.20)); past-month alcohol use (36.1% vs. 7.8%; AOR = 6.80 (4.69, 9.86)); serious past-month distress (23.0% vs. 5.0%; AOR = 4.99 (3.07–8.11)); no health insurance (11.7% vs. 6.2%; AOR = 1.79 (1.07–2.99)); and receipt of food stamps (45.0% vs. 24.0%; AOR = 2.26 (1.55–3.29)). Moving 3 + times in the past year followed a similar pattern, but results were compatible with there being no difference between groups (10.6% vs. 5.5%; AOR = 1.59 (0.95–2.66)). In contrast to other issues examined, English language proficiency was higher among those who reported illicit substance use (4.7% vs. 0.4%; AOR = 0.08 (0.01–0.63)).
Conclusions
Pregnant women who use illicit substances experience higher rates of most psychosocial issues compared to those who do not, reinforcing recommendations for multidisciplinary approaches to care.
Transience in Walks with Diminishing Bias
Authors: Sims Justin Tyler 
Published: April 2023

Abstract
It is well-known that a random walk on Z with biased transition probability p > 1/2 independent of state is transient, tending to positive ∞ almost surely. In this paper, the more general case in which the bias diminishes for higher states is considered. A sufficient condition for transience in such walks is obtained.
Strategies to enhance indigenous Ugandan men’s support for the utilisation of LARCs amongst rural women in Uganda: A qualitative study
Authors: Kibonire Ronald Arineitwe , Ditaba David Mphuthi 
Published: April 2023

Abstract
Globally, many women die due to complications related to childbirth either during pregnancy, childbirth or after birth. The use of contraceptives, especially for long-term reversible methods (LARCs), is one of the best interventions to reduce maternal death. LARCs help the mother to delay pregnancy and allow for longer intervals in childbirth spacing. However, the utilisation of LARCs globally and in Uganda remains low because of limited male partner support. The purpose of this phenomenological qualitative research study was to elicit an understanding of perceptions and beliefs of rural indigenous Ugandan men towards the use of LARCs by rural women. Ultimately the study designed strategies to enhance the uptake of those methods. Purposive sampling was used to identify 65 participants for focus group interviews and 30 for individual interviews comprising married men aged 20 to 49 years. The study was conducted in Rubanda and Kiboga districts of Uganda. The researcher used semi-structured questions for individual and focus group interviews. The data analysis was done by transcribing the interviews, sorting the field notes, organising, and storing the data, listening to recordings, and reading field notes and interviews and then coding and categorising the data to build themes emerging on the phenomenon. The study established that there were perceptions and belief systems among rural indigenous Ugandan men regarding the use of LARCs by their rural women, and these acted as barriers to utilisation. These perceptions included side effects, fears, and desires, in addition to cultural and religious beliefs. The study recommends the strengthening of social, behavioural change communication, strengthening of service provision for LARCs and monitoring and evaluation systems for LARCs. Additionally, policymakers should provide a conducive environment for LARCs services provision and the Ministry of Education and Sports, through health training institutions and universities, should prepare pre-service and in-service healthcare workers to provide LARC services.

Abstract
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants are a fatal pathogen resulting in substantial morbidity and mortality, and posing a great threat to human health with epidemics and pandemics. Methods: Next-generation sequencing (NGS) was performed to investigate the SARS-CoV-2 genomic characterization. Phylogenetic analysis of SARS-CoV-2 genomes was used to probe the evolutionary. Homology protein structure modelling was done to explore potential effect of the mutations. Results: The eighty genome sequences of SARS-CoV-2 obtained from the thirty-nine patients with COVID-19. A novel variant with mutation H625R concomitant with S50L in spike glycoprotein had been identified. Phylogenetic analysis revealed that SARS-CoV-2 variants belong to several distinct lineages. Homology modelling indicated that variant with mutation H625R and S50L increases flexibility of S1 subunit. Conclusions: SARS-CoV-2 genomes are constantly evolving by accumulation of point mutations. The amino acid H625R in combination with S50L may have a significant impact on the interaction between spike glycoprotein and ACE2.

Published: April 2023

Background
To respond to the need to establish infodemic management functions at the national public health institute in Germany (Robert Koch Institute, RKI), we explored and assessed available data sources, developed a social listening and integrated analysis framework, and defined when infodemic management functions should be activated during emergencies.

Objective
We aimed to establish a framework for social listening and integrated analysis for public health in the German context using international examples and technical guidance documents for infodemic management.

Methods
This study completed the following objectives: identified (potentially) available data sources for social listening and integrated analysis; assessed these data sources for their suitability and usefulness for integrated analysis in addition to an assessment of their risk using the RKI’s standardized data protection requirements; developed a framework and workflow to combine social listening and integrated analysis to report back actionable infodemic insights for public health communications by the RKI and stakeholders; and defined criteria for activating integrated analysis structures in the context of a specific health event or health emergency.

Results
We included and classified 38% (16/42) of the identified and assessed data sources for social listening and integrated analysis at the RKI into 3 categories: social media and web-based listening data, RKI-specific data, and infodemic insights. Most data sources can be analyzed weekly to detect current trends and narratives and to inform a timely response by reporting insights that include a risk assessment and scalar judgments of different narratives and themes.

Conclusions
This study identified, assessed, and prioritized a wide range of data sources for social listening and integrated analysis to report actionable infodemic insights, ensuring a valuable first step in establishing and operationalizing infodemic management at the RKI. This case study also serves as a roadmap for others. Ultimately, once operational, these activities will inform better and targeted public health communication at the RKI and beyond.

<p> Diet modulates the development of insulin resistance during aging. This includes tissue-specific alterations in insulin signaling and mitochondrial function, which ultimately affect glucose homeostasis. Exercise stimulates glucose clearance, mitochondrial lipid oxidation and enhances insulin sensitivity. It is not well known how exercise interacts with age and diet in the development of insulin resistance. To investigate this, oral glucose tolerance tests (OGTT) with a tracer were conducted in mice ranging from 4 to 21 months of age, fed a low‑ (LFD) or high-fat diet (HFD), with or without life-long voluntary access to a running wheel (RW). We developed a computational model to derive glucose fluxes, which were commensurate with independent values from steady-state tracer infusions. Both insulin sensitivity indices derived for peripheral tissues and liver (IS‑P and IS‑L, respectively) were steeply decreased by aging and a HFD. This preceded the age‑dependent decline in the mitochondrial capacity to oxidize lipids. In LFD young animals, RW access enhanced the IS‑P concomitantly with the muscle β-oxidation capacity. Surprisingly, RW access completely prevented the age-dependent IS‑L decrease, but only in LFD animals. This study indicates, therefore, that endurance exercise can improve the age-dependent decline in organ-specific IS mostly in the context of a healthy diet. </p>

Authors: DUMITRU (TRIPON) Ioana Maria , COSMA Smaranda Adina 
Published: April 2023

The trend of rural tourism is growing and is becoming increasingly significant for most nations. Rural tourism is believed to have the potential to revive traditional approaches and perspectives on tourism and provide new dimensions to sustainable growth. Romania is regarded as one of the main destinations with a high potential in sustainable tourism development, due to its beautiful, unspoiled rural landscapes, traditions, and rustic lifestyle. Tourism, as a development tool, in rural communities, is one of the major concerns. The scarcity of case studies on rural tourism competitiveness, particularly in Romania, is what inspired the current research. This study attempts to investigate the factors that impact Romania’s rural tourism’s competitiveness and develop a conceptual framework for measuring it. In conducting our research, there were employed both exploratory and descriptive approaches. Secondary data from statistical and published research and studies were gathered, and it were collected primary data through surveys and personal interviews. The objective of the current research was to introduce a distinct and exclusive method of evaluating tourism in rather small regions with unique characteristics and applied and test the proposed model to Maramures region. The paper concludes that measuring and understanding rural tourism competitiveness and dynamics is essential for supporting sustainable development in rural areas, and it is of great importance for practitioners, policy makers and researchers.

Authors: Storozhuk Svitlana , Panchenko Tamara , Dubinina Natalia 
Published: April 2023

Abstract
The article is devoted to the recreational use of the depressed economic territories of coastal cities, using the example of the city of Odessa. As the part of the study, the depressed economic areas of Odessa, located on the Black Sea coast, formed as a result of various factors: economic, technological, etc. were identified and analyzed. Based on the study of international experience redevelopment of abandoned areas, and to identify “recreational potential” of the city of Odessa, the landscape and recreational function have been selected, which will lead to the increase of green areas in the structure of an urban environment and the improvement of sanitary and hygienic conditions in residential and coastal areas. The principles, models and methods of functional planning organization of landscape and recreational formations in coastal depressed areas were formulated. This made it possible to use degraded urban areas effectively to create an ecologically clean, comfortable environment for a recreation of the population and the development of domestic tourism.

Abstract
The efficiency of energy resources and the research and development of electricity generation technologies from renewable energy sources are becoming increasingly important as the use of renewable energy has increased. Northern Cyprus has undertaken attempts to boost the use of renewable energy sources and reduce its reliance on petroleum-based products, similar to many other countries, and as a result, Solar energy utilization has recently grown in this country. This article assesses the current state of PV panel mounting systems and related concerns in Northern Cyprus. In this regard, extensive and reliable data were collected from five distinct sources including authorities, ministries, stakeholders, and inspections. The current state of PV panel mounting systems was evaluated based on data analysis, and the main weaknesses, major concerns, and critical problems were identified. Ultimately, two fundamental recommendations were made to overcome the identified problems. First, developing stringent guidelines to properly use renewable energy sources while minimizing side effects and unwanted losses, second, considering quality control and strict supervision to inspect the implementation of standards.

Abstract
This work is focused on the checking of the correctness of the brazing process of honeycomb seals to stationary elements of aircraft turbine engines. It describes this process, paying attention to the aspects that have a fundamental impact on whether the seal will be brazed to the base as required, or whether unacceptable areas of non-brazing will appear. The aim of the study was to check the possibility of using the ultrasonic method to check the correctness of the brazing process of honeycomb seals and to compare the tests carried out using this method with the mostly used visual tests. The research carried out as part of the work showed very well that there are reasons to use the ultrasonic defectoscopy method to test the correctness of the brazing process of honeycomb seals in the elements of aircraft engines. This method also makes it possible to automate the checking process, fully document it and objectively assess the correctness of the connection. The results obtained in the study provide a very good starting point for further research, the aim of which will be to implement the ultrasonic defectoscopy method for testing the correctness of brazing honeycomb seals into practice in industrial conditions.
Trzy Majdany na Ukrainie. Społeczna pamięć młodzieżowych kontestacji
Authors: Długosz Piotr 
Published: April 2023

Celem artykułu jest przedstawienie społecznej pamięci na temat rewolucji pojawiających się na Ukrainie w ostatnich trzech dekadach. Rewolucja na Granicie, Pomarańczowa Rewolucja oraz Rewolucja Godności są przykładami młodzieżowych rewolucji, w których to studenci odgrywali pierwszoplanową rolę w ich początkowych stadiach. Materiał badawczy został wywołany za pomocą metody jakościowej. W badaniach stosowano wywiady pogłębione wśród respondentów pochodzących z różnych części Ukrainy. Próba badawcza była dobierana w sposób celowy i wyniosła 60 wywiadów. Wyniki badań wskazują, że społeczeństwo ukraińskie lepiej pamięta dwie ostatnie rewolucje. Słaba jest wiedza na temat Rewolucji na Granicie. Dwie pierwsze zostały zapamiętane jako radosne wydarzenia, które napawały optymizmem na przyszłość i zapowiadały zmiany na lepsze. Rewolucja Godności jest traumatycznym doświadczeniem dla badanych i jest postrzegana przez pryzmat strachu, niepokoju, grozy. Widoczne w wypowiedziach badanych są też zawiedzione nadzieje. Liczono na poprawę warunków życia, sytuacji ekonomicznej, lecz to nie nastąpiło. Widoczne są też różnice w ocenach protestów między respondentami mieszkającymi w różnych częściach Ukrainy. Respondenci z zachodniej i centralnej Ukrainy pozytywnie wspominają Majdany i ich następstwa. Respondenci ze wschodniej Ukrainy częściej przywołują negatywną pamięć tamtych wydarzeń i ich skutków.
The youth of the Naddnipryanshchyna during the revolution of 1905–1907 (as per the written ­materials of A. Grinchenko’s and M. Livytska’s ego-documents)
Authors: Dudar Olga , Savchenko Svitlana 
Published: April 2023

Representatives of the younger generation have always - been active participants in revolutionary events in Ukraine both during the rule of the Russian Empire and during the period of Ukraine’s independence. Ego-documents are documents that contain important details that characterize the activity, motivation, and characteristics of young people’s activities: letters, diary entries, and memories. By comparing their content with the descriptions of important events of 1905-1907, it is possible to determine the peculiarities of the participation of young people in attempts to organize the population of certain regions for struggle, as was the case in the city of Lubny in the Poltava region. Written materials related to Anastasia Grinchenko’s and Maria Livytska’s public activities demonstrate the embodiment of revolutionary ideas in behavioral practices of the young generation of political figures of the Naddnipryanshchyna region.

Published: April 2023

Field research was commenced in Rukum West on a standing crop of onion during the flowering stage to assess the effectiveness of foliar sprays of micronutrients on the yield of onion seeds (Allium cepa L.) cv. Red Creol. The experiment was carried out using two levels of Zinc (300 ppm and 375 ppm) and two levels of Boron (240 ppm and 360 ppm) in an RCBD design with treatments applied either separately or in combinations, comprising nine treatments and three replications. The treatments were administered before flowering, during flowering, and after flowering at the seed production stage at 15 days intervals. The application of Zinc and Boron increased total seed yield, seed yield per umbel, seed yield per plant, and germination percentage. The highest seed yield per plant, seed yield per umbel, and seed yield per plot were recorded from Treatment 8 (Zn 375ppm + B 360ppm) i.e. 52.8 gm per plant, 6.12 gm per umbel, and 966.67 kg ha-1 respectively. Similarly, Treatment 1 (Zn300ppm) and Treatment 8 (Zn 375ppm + B 360ppm) showed the highest germination percentage (70%), and Treatment 9 (control) showed the lowest (45%). The treatments did not affect the thousand seed weight.
