Spectroscopy of radicals, clusters, and transition states using slow electron velocity-map imaging of cryogenically cooled anions
Authors: Neumark Daniel
Published: March 2023

Slow electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI) is a high resolution variant of anion photoelectron spectroscopy that has been applied with considerable success over the years to the study of radicals, size-selected clusters, and transition states for unimolecular and bimolecular reactions. Cryo-SEVI retains the versatility of conventional anion photoelectron spectroscopy while offering sub-meV resolution, thereby enabling the resolution of vibrational structure in the photoelectron spectra of complex anions. This article describes recent experiments in our laboratory using cryo-SEVI, including a new research direction in which anions are vibrationally pre-excited with an infrared laser pulse prior to photodetachment.
Adsorption of PFAS onto secondary microplastics: A mechanistic study
Authors: Salawu Omobayo , Adeleye Adeyemi S.
Published: March 2023

Microplastics (MPs) are abundant in aquatic systems. The ecological risks of MPs may arise from their physical features, chemical properties, and/or their ability to concentrate and transport other contaminants, such as per- and polyfluoroalkyl substances (PFAS). PFAS have been extracted from MPs found in natural waters, but there is no mechanistic investigation of the effect of PFAS chemistry and water chemistry on how PFAS partition onto secondary MPs. Here, we studied the influence of pH, natural organic matter (NOM), ionic strength, and temperature on the adsorption of PFAS on MPs generated from PET water bottles. The adsorption of the PFAS to the MPs was spontaneous at 25C, based on Gibbs free energy (G -16 kJ/mol), primarily due to increased entropy. Adsorption reached equilibrium within 7-16 h. Hence, the PFAS will partition to the surface of PET MPs within a few hours to days in fresh and saline waters. Natural organic matter decreased the capacity of PET MPs for PFAS through electrosteric repulsion while higher ionic strength favored PFAS adsorption by decreasing electrostatic repulsion. Increased pH increased electrostatic repulsion, and negated PFAS adsorption. The study provides fundamental information for developing models to predict interactions between MPs and PFAS.

Published: March 2023

The computational design of chiral organic catalysts for asymmetric synthesis is a promising technol-ogy, which may significantly reduce the material and human resources required for the preparation of enantiopure compounds. Herein, for the modelling of catalysts enantioselectivity, we propose to use the Multi-Instance Learning (MIL) approach accounting for multiple catalyst conformers and requir-ing neither conformers selection nor their spatial alignment. A catalyst was represented by an ensem-ble of conformers, each encoded by 3D pmapper descriptors. A catalyzed chemical transformation was converted into a single molecular graph - ondensed Graph of Reaction (CGR) - encoded by 2D fragment descriptors. A whole chemical reaction was finally encoded by concatenated 3D catalyst and 2D transformation descriptors. The performance of the proposed method was demonstrated in the modelling of enantioselectivity of homogeneous and phase-transfer reactions and compared with some state-of-the-art approaches

Analysis of fault ride through the improvement of PV power plant based on artificial neural network
Authors: GENCER Altan
Published: March 2023

The increasing adoption of renewable energy sources in industrial areas, driven by the need to both obtain a grid voltage from renewable energy sources and reduce high electricity bills, has led to an increased demand for solutions that can improve the power quality of these systems. A photovoltaic power plant (PVPP) based on a dc-chopper circuit protection system is proposed for the enhancement of the power quality of PVPP. The aim of the presented protection method is to protect the panels in the PVPP from the harmful effects of the high dc voltage that occurs during grid faults. The adaptive neural network control system is applied in both the T-type inverter and the dc-chopper circuit protection system. The proposed protection system is implemented with a 250 kW PVPP to verify its validity with simulation results during grid fault. This approach can potentially improve the reliability and stability of PVPP, and contribute to the maintain of PVPP into the grid.
Possible environmental applications of a recently developed ammonia isotope monitoring photoacoustic system
Authors: Awuor Ouma Emily , Huszár Helga , Horváth László , Szabó Gábor , Bozóki Zoltán
Published: March 2023

Ammonia is one of the most significant environmental pollutants. Concentration measurements, identifying the sources and studying the transformations in the biosphere are essential, and they are the focus of many investigations. The near-infrared (≈1530 nm) photoacoustic method for simultaneous and selective determination of 14NH3/15NH3 isotopologues reported here can be suitable for monitoring these phenomena and processes. So far, the photoacoustic method has not been used for this kind of examination. The application of our measurement method makes it possible to eliminate the disadvantages of the previous measurement methods. The detection limit of the PA system is 0.14 ppm and 0.73 ppm for 14NH3 and 15NH3, respectively, which can be improved by orders of magnitude with further development of sampling and measurement techniques.
Investigation of the location of an immission measuring point in an urban environment
Authors: Tóth-Nagy Georgina , Németh Fruzsina
Published: March 2023

Life could not exist on Earth without air; this is why its protection is so important. However, air pollution has been known since ancient times, nowadays pollutants from anthropogenic sources occur in much higher quantities. Previously, the primary emission sources were factories due to the industrial revolution, then the development of transportation and the presence of internal-combustion engines made air pollution a major issue. Therefore, more and more efforts have been made over the last decades to reduce the emissions of air pollutants in the industrial sector and the everyday life of the population. Because of this, it is essential to know the factors influencing the air quality of the settlement and to monitor the pollutants properly. Therefore, within the framework of the research work, we examined the possibilities of placing an immission measuring point. To do that, we needed to explore the most important characteristics of the town. Therefore, we examined its structure, meteorological and climatic factors, which fundamentally affect the air quality. We made immission maps using a Geographical Information Program (QGIS) based on the received data. Finally, based on the results, we examined the possibilities of placing an immission measuring station.
How Weighting by Past Vote Can Improve Estimates of Voting Intentions
Authors: Pennay Darren , Misson Sebastian , Neiger Dina , Lavrakas Paul J
Published: March 2023

Polling error for the 2020 US election was the highest in 40 years and no mode of surveying was unambiguously more accurate. This occurred amid several recent polling failures in other countries. Online panels, as the dominant method now used by pollsters to survey voters, are well-positioned to help reduce the level of bias in pre-election polls. Here, we present a case for those pollsters using online panels for pre-election polling to (re)consider using past vote choice (i.e., whom respondents voted for in the previous election) as a weighting variable capable of reducing bias in their election forecasts under the right circumstances. Our data are from an Australian pre-election poll, conducted on a probability-based online panel one month prior to the 2019 Australian federal election. Three different measures of recalled vote choice for the 2016 election were used in weighting the forecast of the 2019 election outcome. These were (1) a short-term measure of recall for the 2016 vote choice obtained three months after the 2016 election, (2) a long-term measure obtained from the same panelists three years after the 2016 election and (3) a hybrid measure with a random half of panelists allocated their short-term past vote measure for 2016 and the remainder their long-term measure. We then examined the impacts on the bias and variance of the resulting estimates of the 2019 voting intentions. Using the short-term measure of the 2016 recalled vote choice in our weighting significantly reduced the bias of the resulting 2019 voting intentions forecast, with an acceptable impact on variance, and produced less biased estimates than when using either of the other two past vote measures. The short-term recall measure also generally resulted in better estimates than a weighting approach that did not include any past vote adjustment. Implications for panel providers are discussed.

Digital writing has become an important part of the daily life of not only the new generation, but also individuals of all ages. Digital writing, which has become a great need for the new generation, is a special issue that concerns pre-service teacher candidates and even takes place in their lives. The purpose of this research is to evaluate the attitudes of pre-service teachers towards writing in the digital environment in terms of different variables and to determine their views. Mixed method was used in the study. The research was carried out in a university in the Aegean Region in the spring semester of the 2021-2022 academic year (n= 264). The participants consisted of pre-service teachers studying in preschool education teaching (n=161) and classroom education undergraduate programs (n=103). In order to obtain qualitative data, interviews were conducted with 12 volunteering students. The Attitude Scale Towards Writing in Digital Environment (DOYAT), developed by Susar Kırmızı, Kapıkıran, and Akkaya (2021), was used to obtain quantitative data. The "open-ended question questionnaire" developed by the researchers was used to obtain qualitative data. Quantitative data obtained were subjected to t-test and analysis of variance using statistical package program. Content analysis was used for the data obtained with the open-ended question form. The attitudes of pre-service teachers participating in the research towards digital writing did not show a significant difference according to gender, class level, and having their own computer. However, it was determined that there was a statistically significant difference according to the time allocated to digital writing. The pre-service teachers who participated in the research stated that they prefer digital writing because it is useful and economical. However, they also stated that writing in digital environment for a long time causes physical health problems.

Authors: Tang Thuy Thi , Tran Duong Hoang Thuy
Published: March 2023

This research investigates parental involvement’s effects on high school students’ self-esteem, anxiety, attitudes, and mathematics achievement. The study included 1,337 students from 11 high schools in Hanoi, Vietnam, chosen via convenience sampling. Participants in this research were asked to answer the questionnaires. The partial least squares structural equation modeling (PLS-SEM) method was utilized to explore the direct and indirect relationships between parents’ involvement and students’ mathematics performance. Results reveal that parental involvement and expectations positively affect students’ mathematics achievement. Parental involvement negatively impacts students’ attitudes toward mathematics; however, parental expectations positively impact students’ attitudes toward mathematics. Parental involvement decreases students’ negative self-esteem, while parental expectation increases students’ negative self-esteem. Notably, parental involvement helps weaken students’ anxiety in mathematics, but the more anxiety students have, the lower their mathematics achievement. It is recommended that parents and students should have more daily conversations. Parents should not place their excessive expectations and involvement on their children.

Authors: Manikas Miltiadis , Leonardos Ioannis , Plakitsi Katerina , Sotiropoulos Konstantinos
Published: March 2023

The acceptance of evolution by Greek students aged 17 has never been actually measured neither via a poll survey nor with the application of any of the existing psychometric tools that have been developed for this purpose. In this research, GAENE 2.1 was chosen because it is a one-dimensional tool that can only measure the acceptance of evolution and does not contain items related to the understanding of evolution and the respondent’s religious beliefs. The assessment of the appropriateness of the tool for our sample was tested with the criteria of Rasch model. Despite the fact that some of GAENE 2.1 items may not show the expected statistical fit and probably overestimates the levels of acceptance of evolution, the tool is appropriated to measure with efficiently and effectively way the acceptance of evolution in the specific sample.

Published: March 2023

This paper investigates the effect of additive manufacturing parameters on the manufacturing quality of selected gear mechanism components. Three input variables, and two output variables were determined. The result was the determination of the most optimal combination of key parameters and the determination of regression equations. The concept of manufacturing objects of a very complex shape, by any person, under various conditions through the use of a low-cost device became the basis for this thesis topic. Curing time, layer thickness, and lift speed are among the basic parameters, with a large range of manipulation. A hypothesis was formulated that these three parameters are crucial to produce a part with the smallest possible deviations from the computer model. A handheld scanner was used to scan the samples and compare them with the CAD model. Based on the study, optimal parameters for layer thickness, curing time and lift speed were proposed.

It is obvious that small hotel enterprises of Transcarpathian region make a significant part of the hospitality segment of the region – they are the ones who receive a large part of guests/visitors/tourists. The activities of most of them are diversified, small-scale and somewhat isolated, these factors have softened the impact of strict quarantine restrictions introduced at different times in 2020-2021. Therefore, the research methodology is based on a sample of questionnaires – interviews provided by 30 enterprises. The research was conducted in the period from January to April 2021, when the restrictions of the red quarantine zone were introduced in the Transcarpathian region of Ukraine during the COVID-19 pandemic. In addition, a literature review of scientific works of domestic and foreign authors was conducted, whose publications relate to some aspects of this research. Much of the research concerns the state and current functioning of the tourism or hospitality industry during the pandemic and the business innovations they employ during the crisis. The results of the survey reflect the highly indicative dynamics of tourist flows in the Transcarpathian region in the period 2000-2020, showing pronounced peaks in the number of visitors (2000, 2003, 2008) and their decline (2001, 2004, 2019), as well as periods of low tourist activity (2014-2016) due to the military and political situation in Ukraine. The study describes the occupancy trends of small and medium-sized hotels in the region for the period 2018-2020. These trends clearly show the consequences of the crisis phenomena that occurred in the economy and society due to the global pandemic. The practical implications of the study lie in possible further recommendations for management decisions that will allow to increase the competitiveness of the hospitality and tourism sector in the region, as well as to implement effective measures in possible crisis situations. Value/originality. Information about the reaction and details of the operation of hotel enterprises of the Transcarpathian region during the global pandemic crisis is useful for understanding the work of the tourism sector in general at different levels – from local to state.

Introduction. Social support of the population is the activation of social and economic activity, the guarantee of economic well-being and development in the state. The necessity of studying modern trends in the functioning and possibilities of improvement of the state financial policy lies in the urgent need to ensure the stable development of a socially oriented market economy in Ukraine. In order to build an effective system of social protection, provision and support, it is necessary to have a sufficient amount of financial resources, which will ensure the effective functioning of the social sphere. The purpose of the article. To determine the relevant aspects of the impact of fiscal policy instruments on ensuring the development of the social sphere, taking into account the trends of digitalization and the use of mathematical methods of analysis. Methodology. The research used general scientific and special methods: theories of cognition, synthesis, grouping, description, comparison, mathematical analysis, graphic representation, theoretical generalization and systematization. Results. The nature and role of tax policy in ensuring the social development of the state are substantiated. The peculiarities of the digitalization of the tax administration as a factor of improvement of the activity of the tax authorities in the context of the performance of fiscal and social functions are emphasized. During the reporting period, considerable attention was paid to the peculiarities of financing the social sphere. It was noted that tax revenues play a key role in the financial resources of local budgets, which makes it possible to cover a wider range of expenditures in the social sphere. Using the methods of mathematical analysis and software products, a graph of the correlation between the revenues of local budgets and expenditures and the social sphere was created. It was found that tax revenues have the greatest impact on the volume of spending on housing and communal services, mental and physical development, and education. In the case of health care expenditures, the same influence of both tax revenues and official transfers was found. Measures to optimize the fiscal policy of Ukraine in the context of stabilizing the social environment in the conditions of martial law are proposed. Conclusion. Fiscal policy should provide a system of state measures to solve certain short-term and long-term tasks facing society, in particular with the help of the tax system. Long-term tasks include achieving economic growth, the maximum level of employment of the country's population and increasing the level of its well-being. Short-term goals can be filling the state and municipal budgets, achieving their balance, stimulating investment and innovation programs that will contribute to the effective development of society.

Evaluating the potential outcomes of energy price reforms is essential for policymakers to assess their effectiveness. In 2016 and 2018, the Saudi government enacted two waves of energy price reforms to curb historically fast-growing electricity demand. We quantify the effects of these measures on regional fuel consumption and carbon emissions.

Objective: The main goal of this retrospective observational clinical study was to investigate the risk factors for fracture in individuals with proximal femoral fibrous dysplasia (FD). Methods: In individuals with FD of the proximal femur according to whether or not they had experienced a hip fracture, we looked at body mass index, bilateral radiographs on both sides, femoral neck shaft angle measures, and markers of bone metabolism. Age, sex, clinical classification, anatomic classification, femoral neck shaft angle, pro-collagen type I N-terminal pro-peptide, type I collagen C-terminal telopeptide, and osteocalcin levels were the nine clinical variables used for univariate analysis. Multivariate logistic analysis was then applied to factors that showed out in the univariate study. Results: In univariate analysis, the clinical classification, anatomic classification, femoral neck shaft angle, and osteocalcin level were found to be statistically significant risk variables for fracture. Multivariate analysis revealed that the osteocalcin level, femoral neck shaft angle, and anatomic classification were still important risk variables. Conclusion: In patients with FD of the proximal femur, the osteocalcin level, the femoral neck shaft angle, and other key risk variables for fracture could be used to direct the execution of a fracture prevention strategy.
