Authors: Matseluk Ye. M. , Charnyy D. V. , Levytska V. D. , Marysyk S. V.
Published: January 2022

The current state of water quality formation in surface water bodies, which serve as sources of drinking water supply in the Dnieper river basin, was considered. The water treatment technologies currently used in Ukraine, were analyzed. The inconsistency of these technologies with the current water quality in these sources of water supply was established, as these technologies are not quite suitable for the purification of water with a significant organic component of any genesis. It was found that one of the main factors that influences the quality of water in water bodies in the warm period is phytoplankton, especially during their "flowering. The factors accompanying this phenomenon were shown, the development trends and their influence on the operating water treatment systems were analyzed. It was considered the feasibility of using reagents with the effect of oxidation of the organic component of the source water, in particular chlorine dioxide, the use of which is effective in disinfection of chlorine-resistant microbiota and phenols oxidations. Moreover, in the conditions of the expected increase in the concentration of mycocystins, chlorine dioxide can be, by analogy with ozone, a fairly effective oxidant of these toxins with a prolonged disinfection effect.

The potential development areas of water treatment systems by intensifying bio-physico-chemical processes on the basis of the existing typical capacitive and package units of water treatment plants are given. The perspective areas of scientific and technological developments for substantiation of effective solutions on modernization of existing water treatment facilities were established in these conditions, namely it is reasonable to consider only those solutions, which provide effective purification of water with high concentration of phytoplankton without comprehensive or radical change of water treatment technology. That is, these approaches should make maximum use of existing treatment facilities, either by their reconstruction, or with the use of new reagents, or a combination of both.
Irrigation efficiency depending on water cost

Published: January 2022

The article provides an analytical review of the achieved crop yields under irrigation in experimental and production conditions. For today, the best production experience in the use of irrigated land indicates that, subject to all agrotechnical requirements, the yield of early grain crops reaches 8-10 t / ha, corn - 10-14 t / ha, oilseeds - 4-6 t / ha, vegetable crops - over 60 t / ha, which is about 90% of their productivity achieved in the experiments of scientific institutions. The comparative assessment of grain production in different climatic zones of Ukraine for the period of the most intense climatic change shows that over the past thirty years, the share of grain production in the Steppe zone has decreased from 45 to 35% of the total in Ukraine. The analysis of service cost for the transportation of water for irrigation in the southern regions of Ukraine is given. It was revealed that, despite a unified standard method for calculating the cost of water transportation, its price varies significantly by operational units of the State Agency for Water Resources of Ukraine. The main factors of fluctuations in the cost and fees for the transportation services of water for irrigation are the budgetary funding level of operating organizations, providing these services, the number of water transfers, the volume of actual irrigation on irrigated lands, the share of irrigated areas in the service area.
The economic assessment of irrigation efficiency when having different water and other technological costs, taking into account the depreciation of capital investments, indicates that having a water price of 4,0-5,0 UAH/m3, the gross profit from growing the most profitable field crops is 35-40 % higher than the efficiency in rainfed agriculture. At the cost of water is 3,0-3,5 UAH/m3 and the use of the production capacity of the inter-farm irrigation network by 60-70%, financial prerequisites will be created for the effective operation of these networks.

Published: January 2022

The trends in the development of virtual reality in the era of digitalization are investigated, a model of the process of quantizing social systems is determined. The research methodology is the information approach, the principles of the quantum paradigm, the sociophilosophical analysis of topical problems of objective reality. Attention is focused on the fact that social systems are being transformed under the influence of digitalization processes that have covered all spheres of life. A new, quantum paradigm is outlined, based on information and information processes that take place in hyperreality and the environment. The quantization of social systems as an impending inevitability of the future in its essence presupposes the digitization of objective reality and the creation of virtual models of social systems, defining their activity and functionality in hyperreality. Consequently, the quantization of social systems will accelerate the process of virtualization of social reality, uniting the world community into one digital Universe with many multidimensional and parallel systems

Published: January 2022

During the Covid-19 pandemic, the government issued a policy through Large-Scale Social Restrictions and the impact was felt on the unsustainable availability of various food commodities, one of which was broiler chicken meat. Broiler chicken is one of the animal protein food products that is favored by people from various circles because it has a relatively cheaper price compared to other meat commodities that provide animal protein, is easy to obtain, and has good organoleptic quality. The purchasing power of the people of the Special Region of Yogyakarta (DIY) is also increasing due to increased nutritional awareness related to the fulfillment of animal protein. The broiler production process contains uncertainty because it is seasonal. This causes a fluctuating price change. Fluctuations in broiler prices are not a new phenomenon in the DIY. Price fluctuations usually occur at certain times such as during religious holidays and this phenomenon occurs repeatedly every year. So we need a broiler supply chain research to maintain price stability using a dynamic simulation system model of the broiler chicken supply chain in DIY. This study develops a Causal Loop Diagram (CLD) and Stock and Flow Diagram (SFD) of system dynamic model of the broiler supply chain in the DIY and simulates the model using Powersim Studio 10 software. The simulation is confirmed verified and valid, therefore for the next research model can be used to solve the problem by generating policy scenario.

Hydraulic fracturing operation is the common method to stimulate an oil well in order to make the permeability around the well become higher by injecting a mixing of fracturing fluid and proppant. Hopefully, this higher permeability can contribute to increase the production of oil and/or gas. The fundamental laboratory assessment of fracturing fluid as a part of injected component is important to be conducted before field scale implementation. One of the fundamental assessment is the static laboratory testing. In this test, the fracturing fluid sample is measured to obtain the data about its properties such as water quality, rheology, crown time and breaking time. These properties give important role to calculate the performance of the hydraulic fracturing field scale operation would be. In this research, we conducted the static laboratory testing for fracturing fluid in sensitivity of concentration which are 35, 40 and 45 systems. Every concentration have been measured its properties in order to compare each other to evaluate and select best fracturing fluid candidate for field scale application.

Published: January 2022

To produce optimally good quality shallots, proper cultivation techniques are required. Efforts that can be made include modifying the environment in which plants grow. Alternative efforts to increase the quantity and quality of agricultural products, especially shallots can be done by using organic fertilizers and the use of Trichoderma sp. as a plant growth promoting agent, as well as improving the quality of organic fertilizers. The purpose of this study was to determine the role of Trichoderma in increasing the ability of plants to absorb nutrients from the growing media and to determine the best type of organic fertilizer to increase the growth and yield of shallots. The research was conducted at the experimental field of the Faculty of Agriculture, UPN "Veteran" Yogyakarta, Wedomartani, Sleman, Yogyakarta Special Region, at an altitude of approximately 104 meters above sea level. The time of the research is from May to July 2021. This study was arranged in a factorial Completely Randomized Block Design with 3 replications. The first factor is the type of manure (P1: without manure, P2: cow manure and P3: goat manure). The second factor was inoculation of Trichoderma sp isolates (I0: without inoculation of Trichoderma sp. isolates. and I1: by inoculation of Trichoderma sp. isolates). Based on the results of this study, it can be concluded that the addition of cow and goat manure was able to produce more leaves and plant height than without the addition of manure, although it did not show a significant effect on the yield of shallot bulbs. There is no significant difference between cow manure and goat manure. Trichoderma inoculation has not had a significant effect on the growth and yield of shallots

The report traces the role of the outstanding Soviet slavist, professor S. Bernstein in the revival of Russian Slavic studies in the second half of the XX century. The author relies on the memoirs of scientists of the Institute of Slavic Studies and Moscow University and on the materials of the book of memoirs of S. Bernstein “Zigzags of Memory” (2002). The name “Zigzags of memory” correlates not only with the memories of the scientist, but also with the zigzags of the history of Russian Slavic science. The author traces the path of Slavic science in the Soviet period, which was thorny due to the well-known persecution of slavistics in the 20–30 years of the XX century. In the middle of the XX century, prof. S. B. Bernstein became the organizer of the revival of the entire Slavic branch. The role of the scientist in the organization of the Slavic department of Moscow State University and the training of slavists, in the work of the Institute of Slavic Studies, in the development of a number of significant science areas is shown: slavic dialectology and linguogeography, comparative historical grammar of slavic languages, ethnolinguistics and slavic antiquities, Cyril and Methodius problems, etc.

The paper offers an interpretation of some Rezyan toponyms. The mountainous landscape of Rezya has determined the importance of the spatial landmarks ‘top — bottom’, ‘west — east’. The Rezyan language widely uses compound prepositions to express these relations, often in combination with adverbial particles (cf. ‘there-in’). An archaic feature is the use of idioms for the orientation marks ‘right’, ‘left’.

In the work on the material of vocabulary, as well as rituals, beliefs and folklore of the Russian North, the symbolics and ritual functions of tea and tea drinking in folk culture are reconstructed. The place of tea in the diet, the organization of tea drinking are considered; reveals the parameters by which the quality of tea is assessed and functions of tea in family rituals. Drinking tea in folk culture acquires a special ceremoniality and often performs the functions of social regulation: social skills are tested during tea drinking and social relations are built. In family rituals, tea takes on the symbolic functions of wine and beer, bread and bread and salt, forming a functionally close “tea-sugar” pair. Often, tea is opposed to bread as an empty and non-nutritious product, a symbol of luxury and excess.
Женский голос в современной польской поэзии

Published: January 2022

Women have been involved in the creation of Polish literature since the 17th century. A new page in the history of Polish literature, which came after 1989, is associated with the rapid development of feminism. An important phenomenon of poetry at the beginning of the XXI century was the abundance of female names: at this time, the authors of the older generation, such as V. Szymborska, E. Lipska, K. Miłobędzka, J. Hartwig, continue to create, but new names also appear: J. Mueller, M. Cyranowicz, J. Bargielska, M. Podgórnik, M. Lebda, J. Fiedorchuk, M. B. Kielar. Contemporary Polish women’s poetry is very soulful, sensual and deep, it is filled with empathy, and at the same time it is subjective. Corporeality and frankness become one of the characteristic features of women’s writing: women’s poetry tells more openly and directly about the most intimate experiences.

Inference With Cross-Lagged Effects - Problems in Time
Authors: Driver Charles C
Published: January 2022

The interpretation of cross-effects from vector autoregressive models to infer structure and causality amongst constructs is widespread and sometimes problematic. I describe problems in the interpretation of cross-effects when processes that are thought to fluctuate continuously in time are, as is typically done, modeled as changing only in discrete steps (as in e.g. structural equation modelling) -- zeroes in a discrete-time temporal matrix do not necessarily correspond to zero effects in the underlying continuous processes, and vice versa. This has implications for the common case when the presence or absence of cross-effects is used for inference about underlying causal processes. I demonstrate these problems via simulation, and also show that when an underlying set of processes are continuous in time, even relatively few direct causal links can result in much denser temporal effect matrices in discrete-time. I demonstrate one solution to these issues, namely parameterizing the system as a stochastic differential equation and focusing inference on the continuous-time temporal effects. I follow this with some discussion of issues regarding the switch to continuous-time, specifically regularization, appropriate measurement time lag, and model order. An empirical example using intensive longitudinal data highlights some of the complexities of applying such approaches to real data, particularly with respect to model specification and interpretation.
Variations in Earth's 1D viscosity structure in different tectonic regimes
Authors: Osei Tutu Anthony , Harig Christopher
Published: January 2022

Past estimates of Earth’s mantle viscosity profile using the long-wavelength geoid suggest an increase in viscosity from the upper to lower mantle of roughly 2-3 orders of magnitude. We use a spatio-spectral localization technique with the geoid to estimate a series of locally constrained viscosity profiles covering two unique regions, the Pacific and Atlantic hemispheres. The Pacific region exhibits the conventional Earth's 1D rheology with a factor of roughly 80-100 increase in viscosity occurring at transition zone depths. The Atlantic region in contrast does not show significant viscosity jumps with depth, and instead has a near uniform viscosity in the top 1000 km. Our inferred viscosity variations between the two regions could be due to the prevalence of present-day subduction in the Pacific region and the relative infrequence of slabs in the Atlantic, combined with a possible hydrated transition zone and mid-mantle in the Atlantic region by ancient subduction.

Background: The mental health impacts of the COVID-19 pandemic remain a public health concern. High quality synthesis of extensive global literature is needed to quantify this impact and identify factors associated with adverse outcomes. Methods: We conducted a rigorous umbrella review with meta-review and present a) pooled prevalence of probable depression, anxiety, stress, psychological distress, and post-traumatic stress, b) standardised mean difference in probable depression and anxiety pre-versus-during the pandemic period, and c) comprehensive narrative synthesis of factors associated with poorer outcomes. Databases searched included Scopus, Embase, PsycINFO, and MEDLINE dated to March 2022. Eligibility criteria included systematic reviews and/or meta-analyses, published post-November 2019, reporting data in English on mental health outcomes during the COVID-19 pandemic. Findings: Three hundred and thirty-eight systematic reviews were included, 158 of which incorporated meta-analyses. Meta-review prevalence of anxiety symptoms ranged from 24.4% (95%CI: 18-31%, I2: 99.98%) for general populations to 41.1% (95%CI: 23-61%, I2: 99.65%) in vulnerable populations. Prevalence of depressive symptoms ranged from 22.9% (95%CI: 17-30%, I2: 99.99%) for general populations to 32.5% (95%CI: 17-52%, I2: 99.35) in vulnerable populations. Prevalence of stress, psychological distress and PTSD/PTSS symptoms were 39.1% (95%CI: 34%-44%; I2: 99.91%), 44.2% (95%CI: 32%-58%; I2: 99.95%), and 18.8% (95%CI: 15%-23%; I2: 99.87%), respectively. Meta-review comparing pre-COVID-19 to during COVID-19 prevalence of probable depression and probable anxiety revealed standard mean differences of 0.20 (95%CI=0.07-0.33) and 0.29 (95%CI=0.12-0.45), respectively. Conclusions: This is the first meta-review to synthesise the longitudinal mental health impacts of the pandemic. Findings show that probable depression and anxiety were significantly higher than pre-COVID-19, and provide some evidence that that adolescents, pregnant and postpartum people, and those hospitalised with COVID-19 experienced heightened adverse mental health. Policymakers can modify future pandemic responses accordingly to mitigate the impact of such measures on public mental health.

Cancer-related Posttraumatic growth and Posttraumatic stress disorder: how are they connected and what are their correlates?
Authors: Baník Gabriel , Dědová Mária , Vargová Lenka
Published: January 2022

PurposeCancer is a stressful life event that can lead to specific posttraumatic reactions. Posttraumatic stress disorder (PTSD) and Posttraumatic growth (PTG) are two main posttraumatic reactions that are related to each other, and both have different correlates.MethodsThe linearity of the relationship between PTG and PTSD as well as the different socio-demographic, cancer-related, emotional and psychological correlates were analyzed in patients with cancer (N = 126).ResultsThe relationship between PTG and PTSD was found to be more curvilinear than linear. PTSD was more strongly related to psychological factors (e.g., anxious preoccupation, hope-helplessness, resilience) while PTG was strongly related to existential factors (e.g., self-transcendence, religiosity).ConclusionThe results show that cancer-related PTSD and PTG are specifically related constructs which are related differently to particular correlates.
How causal is a reciprocal effect? Contrasting traditional and new methods to investigate the reciprocal effects model of self-concept and achievement
Authors: Hübner Nicolas , Wagner Wolfgang , Zitzmann Steffen , Nagengast Benjamin
Published: January 2022

The relationship between students’ subject-specific academic self-concept and their academic achievement is one of the most widely researched topics in educational psychology. A large body of this research has considered cross-lagged panel models (CLPMs), oftentimes synonymously referred to as reciprocal effects models (REMs), as a gold standard to investigate the causal relations between the two variables and has reported evidence for a reciprocal relationship between self-concept and achievement. However, more recent methodological research questioned the plausibility of assumptions that need to be satisfied in order to interpret results from traditional CLPMs causally. In this substantive-methodological synergy, we aimed at contrasting traditional and more recently developed methods to investigate reciprocal effects of students’ academic self-concept and achievement. Specifically, we compared results from CLPMs, from full forward CLPMs (FF-CLPMs), and from random intercept CLPMs (RI-CLPMs) with two weighting approaches developed to study causal effects of continuous treatment variables. To estimate these different models, we used rich longitudinal data of N = 3,757 students from lower secondary schools in Germany. Results from CLPMs, FF-CLPMs, and weighting methods support the reciprocal effects model, particularly when considering math self-concept and grades. In contrast, results from the RI-CLPMs were less consistent. Implications from our study for the interpretation of effects from the different models and methods as well as for school motivation theory are discussed.

Yet these studies may not capture the richness of exploration strategies that people exhibit in more complex environments. We study human behavior in a large data set of 29,493 players of the richly-structured online game "Little Alchemy 2''. In this game, players start with four elements, which they can combine to create up to 720 complex objects. We find that players are driven to create objects that empower them to create even more objects. We find that this drive for empowerment is eliminated when people play a version of the game that lacks recognizable semantics, indicating that they use their knowledge about the world to guide their exploration. Our results suggest that the drive for empowerment may be a potent source of intrinsic motivation in richly structured domains, particularly those that lack explicit reward signals.

The language used in job advertisements contains explicit and implicit cues, which signal employers’ preferences for candidates of certain ascribed characteristics, such as gender and ethnicity/race. To capture such biases in language use, existing word inventories have focused predominantly on gender and are based on general perceptions of the ‘masculine’ or ‘feminine’ orientations of specific words and socio-psychological understandings of ‘agentic’ and ‘communal’ traits. Nevertheless, these approaches are limited to gender and they do not consider the specific contexts in which the language is used. To address these limitations, we have developed the first comprehensive word inventory for work and employment diversity, (in)equality, and inclusivity that builds on a number of conceptual and methodological innovations. The BIAS Word Inventory was developed as part of our work in an international, interdisciplinary project – BIAS: Responsible AI for Labour Market Equality – in Canada and the United Kingdom (UK). Conceptually, we rely on a sociological approach that is attuned to various documented causes and correlates of inequalities related to gender, sexuality, ethnicity/race, immigration and family statuses in the labour market context. Methodologically, we rely on ‘expert’ coding of actual job advertisements in Canada and the UK, as well as iterative cycles of inter-rater verification. Our inventory is particularly suited for studying labour market inequalities, as it reflects the language used to describe job postings, and the inventory takes account of cues at various dimensions, including explicit and implicit cues associated with gender, ethnicity, citizenship and immigration statuses, role specifications, equality, equity and inclusivity policies and pledges, work-family policies, and workplace context.

Occurrence and variety of flowering host plant of native Bombus pollinators are viewed as basicalternatives than the imported species. The use of native bumblebee species for pollination wasconsidered more significant than imported bumblebees to reduce environmental impact and pestproblems. B. haemorrhoidalis is the most dominant species of Chitwan Annapurna Landscape inagricultural and wild flora during April to September 2019. We followed assessable walking trailsand used insect net for sample collection. The effect of different environmental variables on the floralhost plant resources of this native bumblebee was examined. With eight locations ranging from 1407to 2506 meters above sea level, twenty-seven species of seventeen plant families were identified aspollen and nectar foraging host plants. B haemorrhidalis distribution frequency is correlated withrelative humidity (0.07438968) and altitude (0.495657857). The most visited plant family wasBalsaminaceae and plant was Imatian scrabida. This study gives the knowledge of abundance of hostplants, ecological and biological relationship of the B. haemorrhoidalis in Nepal

Forecasting Stock Market Momentum in Nepal: Application of Fuzzy Logic Model
Authors: Koirala John , Rai Swachhanda Aabhas
Published: January 2022

Background: Stock market experts analyse various indicators to estimate the stock market, including historical prices, economic analysis, industry analysis and company analysis, but this study uses historical prices for the NEPSE index, making forecasting more precise.
Purpose: The purpose of this study is to explore short-term stock market momentum using fuzzy logic. The study also aims to establish a suitable fuzzy model to predict stock momentum, reduce the risk, and make the right investment decision.
Methodology/Design: This study employed exploratory research design to understand the problem of chaotic decision making in the stock market. The mathematical method employed in this study is membership functions, which are part of fuzzy logic. This includes only the commercial banks, as it has the highest market capitalization, 53.11% of total market capitalization. Using 14-day past data as a base, the suggested fuzzy model determines the stock index’s momentum over the next 5 days.
Findings: The forecasted trend value for the Nabil, Civil, and Prime Commercial bank is 0.92, 0.92, and 0.80, which shows a bullish trend. Compared to previously collected data, the findings closely reflect the expected real-world values.

A systematic review of dividend policy in relation to stock price volatility
Authors: Bhatta Sheena , Duwal Bal Ram
Published: January 2022

When it comes to determining a dividend policy that would maximize shareholder value, focusing merely on how much of the firm’s profit is necessary for dividend distribution and reinvestment is insufficient. It is critical to analyze the impact of their dividend choice on the stock price.The purpose of this study is to scrutinize the impact of dividend policy on stock price volatility. The report investigated the relationship between the dividend policy and stock price volatility taking 8 articles between 2010 to 2020. Likewise, following a systematic literature review method, the study critically analyzed the selected articles based on their strengths and weaknesses. The findings suggest that, in most of the cases demonstrated by authors, dividend policy has a significant negative relationship with the stock price volatility. The stock’s price volatility often decreases after the declaration of dividend payout ratio and dividend yield. Based on the results of this study, it can be implied that, managers of manufacturing companies and banks, those listed in the stock exchange, may be able to reduce the price volatility of their stock by increasing dividend payout and dividend yield. Since the study is limited to 4 databases, further studies could include some more articles from top-rated databases that signify dividend policy in diverse sectors to derive even more accurate results.

Published: January 2022

Introduction: Cleft lip and cleft palate (CLCP) affects several systems and functions of the child and result in social and psychological problems.Therefore early repair of CLCP is imperative. Every cleft center follows its own surgical treatment protocol. Before closure of palatal defects, babies with cleft palate have great difficulty in feeding. To overcome this feeding difficulties, use of special bottles, nipples, initial palatal obturator therapy are used. The first exposure of those children are primarily the medical doctors including pediatricians from where they are generally referred to the concerned speciality for repair of CLCP. The aim of this study was to assess the knowledge and practice of orofacial clefts and feeding plate obturator among medical doctors working in Kanti Children’s Hospital (KCH).
Method: This was a questionnaire based survey among medical doctors working in KCH. The pretested questionnaire with 7 questions each on the knowledge and practice of feeding plate obturator was distributed among the medical doctors and data was collected. The data collected were subjected to statistical analysis using frequency of responses and percentages.
Results: Of the total 57 study participants, 32 (56.1%) were males and 25 (43.9%) were females. Majority i.e. 61.4% belonged to 31-40 years age group. 91.2% study participants faced the cleft lip/ palate related feeding difficulties 0-5 times/month while 5 (8.8%) faced this condition 6-10 times/ month. Majority of the infants who were less than 28 days (43.9%) attended the OPD due to difficultyin feeding/ swallowing (57.9%) followed by regurgitation/ aspiration (22.8%). 49.1% of the participants thought feeding plate oburator as the best way to feed a cleft patient on discharge from hospital. In their clinical practice, three fourth of paticipants (70.2%) had never seen a patient with feeding plate obturator, half of the participants (50.9%) didn’t advise for feeding plate obturator for patients withcleft palate and 89.5% were not aware of the replacement of feeding plate obturator.
Conclusion: There is low exposure regarding the feeding plate obturator among medical doctors in KCH which needs to be reinforced through meaningful continuing education and training programs.
