Noble metals are used in a plethora of applications, from electronic and communication equipments, to aerospacial engines, mobile phones and catalytic convertors. Currently, there is a continuous interest in the recovery of noble metals from waste, as their natural reserves are limited. Herein, the paper presents studies on the recovery of platinum from spent automotive catalysts. The process involves two steps - dissolving of platinum, followed by its precipitation into a hexacloroplatinum complex. The optimum reaction conditions for dissolving Pt from the spent automotive catalyst use a mixture of H2O2 + HCl (1:5.5 molar ratio) at 30°C, for 8 h. For the full recovery of platinum from the solution, the volumetric ratio of 4:1 between the platinum solution and the precipitating ammonium chloride solution is optimum. In addition, studies regarding the precipitation time and temperature have also been performed. All the obtained precipitates were analyzed by X-ray powder diffraction and showed the structure of the hexachloroplatinic (NH4)2[PtCl6] complex, with high purity. Upscaling of the processes for technological transfer show promising results in the recovery of platinum from spent automotive catalysts.
Removal of trace organic pollutants and generation of halogenated disinfection by-products in membrane UV/chlorine combined process
Authors: Yu Yafei , Lei Yu , Fan Mengge , Lei Xin , Zhao Shanshan , Yang Xin
Published: November 2022

In this study, the degradation kinetics and degradation mechanism of 23 trace organic pollutants (TrOCs) in the secondary effluent of sewage by the combined membrane-UV/chlorine process were investigated, and the halogenated disinfection by-products (X-DBPs) in the combined process were investigated and its generation potential (X-DBPsFP), and the cytotoxicity and genotoxicity of the treated water samples were also evaluated. The results showed that membrane pretreatment could effectively promote the degradation of TrOCs in UV/chlorine system, and nanofiltration (NF) was more effective than ultrafiltration (UF). Compared with UF, NF intercepts more dissolved organic matter (DOM), thus weakening the light shielding effect, chlorine consumption and radical quenching to a greater extent. It is found that the degradation mechanism of TrOCs can be divided into the following four categories: Ho˙ dominated, RHS dominated, chlorine and RHS jointly dominated and chlorine dominated. Membrane pretreatment can well reduce the formation of X-DBPs, among which UF and NF reduce the formation of haloacetamide (HAMs) and trihalomethanes (THMs) most significantly, while NF reduces the formation of X-DBPs and X-DBPsFP and the toxicity of water samples much stronger than UF. In addition, NF UV/chlorine can significantly remove the precursors of X-DBPs, so as to effectively control the enhancement of cytotoxicity and genotoxicity of water samples in the post chlorination process. The research results promote the development of advanced sewage treatment technology and provide theoretical guidance for related research.
May bananas go extinct? The epidemic of Panama disease. A review
Authors: Waraczewski Robert , Sołowiej Bartosz G.
Published: November 2022

Bananas are one of most popular fruits worldwide. Estimated export in 2020 reached a record high of 22.2 million tons, a 1.7% growth compared to 2019. They are cultivated in Asia, Africa, Australia, Latin, and South America. People value them for their taste, easy accessibility, low price, plenty of nutrients and vitamins, preparation versatility. They contain vitamins A, C, E, K and from B group, fibre, magnesium, phosphorus, calcium, and potassium. In some countries bananas and plantains are the basis of diet and are consumed daily, like rice or potatoes. Unfortunately, these wonderful fruits may soon cease to exist. An illness called Panama disease caused by Fusarium oxysporum fungus is responsible for destroying 950,000 metric tonnes of crop yields annually. Previous variant of that disease almost caused a total wipeout of former mostly cultivated banana cultivar Gros Michel. In this work Panama disease history, biology, and preventionare reviewed.

The biodiversity of weed communities of dent maize, narrow-leaved lupin and oat in relation to cropping system and weed control
Authors: Głowacka Aleksandra , Flis-Olszewska Ewelina
Published: November 2022

The aim of the experiment was to assess the effect of cropping system and as well as various methods of weed control on the biodiversity of the weed community of dent maize, narrow-leaved lupine and spring oat. The data used in the study came from a three year field experiment carried out at the Experimental Station in south-eastern Poland (50°42'N, 23°16'E). The following factors were studied: 1. Cropping system – sole cropping and strip intercropping; 2. Weed control – mechanical and chemical. Changes in the diversity of the segetal flora are analysed using the species richness index (S), the Shannon-Wiener diversity index (H’), the Margalef index (R), the Simpson dominance index (D) and Pielou’s evenness index (J’). The use of chemical weed control increased the diversity of the weed community in all species tested compared to mechanical weed regulation. Chemical weed regulation significantly decreased the value of Simpson dominance index due to the limitation of the occurrence of dominant weed species. Strip intercropping increased weed biodiversity, however, the influence of cropping systems depended on the crop species and the weed controlmethod used.

Published: November 2022

According to previous studies, the prevalence of musculoskeletal symptoms among call center operators is high. However, although this is a developing occupation in Portugal, there is a lack of studies assessing this issue as well as its associations with different risk factors. Therefore, the aim of this study is to investigate the 7-day and 12-month prevalence of musculoskeletal symptoms among Portuguese call center operators and their associations with gender, body mass index, hours of work and sitting time. The study was conducted in a call center company in Portugal. One-hundred and forty-eight workers agreed to participate, and filled out questionnaires to evaluate sociodemographic, anthropometric, and occupational variables, as well as the Nordic Musculoskeletal Questionnaire (NMQ) to assess musculoskeletal symptoms in the last 7 days and 12 months of 9 body regions. NMQ revealed the 12-month prevalence of musculoskeletal symptoms, the 3 most affected body regions were the neck (56.1%), the low back (54.7%) and the shoulders (43.9%). And the 7-day prevalence, the three most affected body region were the same, but in different percentages: low back (31.8%), neck (23.6%) and shoulders (21.6%). Significant associations were found between gender and reporting symptoms in the wrist/hands (p=0.033) and the knees (p=0.031), with females reporting significantly more symptoms than males; and between body mass index and reporting symptoms in the thighs/hips, with overweight operators reporting more symptoms (p=0.010). No significant associations were found for the hours of work, neither in sitting time. Conclusion: Workplace interventions are needed to decrease the prevalence of musculoskeletal complaints among call center workers.

Authors:   The Korean Agricultural Economics Association, Kim Dong Hwi , Kim Yoon Hyung , Kim Yoon Hyung
Published: November 2022

This study analyzed the benefits of the B2B online agricultural exchange, which is promoted by the government for digital transformation in the distribution sector as the Fourth Industrial Revolution technology is introduced and the agricultural distribution environment is changing rapidly owing to COVID-19. Currently, the Korean government is conducting the national B2B online agricultural exchange, where sellers, including producer organizations and agricultural corporations, can make direct transactions and buyers, including public market wholesale corporations, intermediaries, and trade participants, can purchase agricultural products through the online platform, regardless of time and location.
Against this backdrop, we analyzed the potential benefits of the online agricultural exchange, divided into those from the reduction in distribution stages and from the increase in user convenience. For the analysis, benefits from the reduction in distribution stages are divided into logistics cost saving, shrinkage loss reduction, and commission reduction. Benefits from the increase in user convenience are divided into shipper’s saving of search cost and buyer’s saving of transaction cost. Assuming that the online agricultural exchange is worth KRW 500 billion, the expected economic benefit was analyzed to be about KRW 38.3 billion per year.

Published: November 2022

This study analyzed the effect of the sensitivity of news related to onions on producers' decision-making on cultivation areas and market supply and demand. We collected onion-related article data and derived the sentiment index through sentiment analysis using neural networkbased learning. We estimated the cultivation area function, including the sentiment index we made. We analyzed the impact of news sensitivity on the onion market by constructing an onion market supply and demand model. Then, we gave a sentiment index shock to the cultivation area to examine the impact on the onion market. We also explored the sensitivity analysis to emphasize the news in June, July, and August plays an important role in the supply side. To the best of our knowledge, our approach using sentiment index in the agricultural model is the first trial. Therefore, our study can introduce an approach to improve the accuracy of modeling for agriculture and apply it to the area of agricultural economics.
Impact of COVID19 on Household Food Waste
Authors:   The Korean Agricultural Economics Association, Kim Jeong-hwan , Lee Ji Yong
Published: November 2022

The pandemic of COVID19 has significantly changed consumers' food consumption and waste behaviors. Specifically, the main section of households’ food consumption shifted from food awayfrom- home to eating at home which could be connected with household food wastes. This study estimated the effect of COVID19 on the amount of household food wastes by using Consumer Behavior Survey for Food(CBSF) data. We analyzed the effect of COVID19 on household food waste emissions using the ordered logit model given the theory that food waste emissions are influenced by food prices and opportunity costs of food utilizing. We found that household food wastes increase after COVID19, and a change of the opportunity cost of food utilizing causes increase in food wastes. Based on results, we provide policy implications regarding reduction in food wastes.

Authors: Musyaffa Nadhif Fadhlan , Paksi Arie Kusuma , Myarta Lalu Radi
Published: November 2022

This study discusses the paradigm used by the United Nations in governing relations among countries on sea-related issues based on the United Nations Convention on the Law of the Sea. Laws/regulations on sea-related issues have undergone amendments since their inception in 1958 to adjust to the current condition, factors that trigger sea-related disputes, as well as global political and economic dynamics. Reforms in the regulatory mechanism on sea-related issues were marked by the enactment of the United Nations Convention on the Law of the Sea in 1982. This paper presents an analysis and evaluation of the paradigms used by the United Nations in establishing the mechanisms of sea-related issues through the United Nations Convention on the Law of the Sea. Content analysis was employed to analyze the law based on three indicators; actors, authorities, and governance representing the three paradigms; realism (competition), liberalism (collaboration), and constructivism (historical and social construction). The analysis showed that the United Nations Convention on the Law of the Sea concerning the regulation mechanism on sea-related issues between countries is strongly influenced by the realism paradigm.

Early human development is important for psychological and psychosocial growth. Parental practices include parents’ behaviors and communication patterns with their children, which have short- and long-term effects on their children’s social functioning in areas such as morality, social development, psychological development, peer play, and academic achievement. This study aims to assess the relationship between perceived parental style and emotional regulation abilities among Indian young adults. Following purposive sampling, data was collected from two hundred and fifteen young adults in India. The findings show cognitive reappraisal and emotional regulation have a significant positive relationship with permissive and authoritative parenting. Cognitive appraisal shares no significant relationship with authoritarian parenting. Excessive suppression did not share a significant relationship with any of the parental styles.

Published: November 2022

Introduction. Hospitalized cancer patients experience limitations in their daily activities resulting from the severity of their condition. Such changes alter patients’ sensory perception and hinder their mobility, thus predisposing them to the development of PI. Objective. The goal of this study was to analyze the prevalence of PI and associated factors in hospitalized cancer patients. Materials and Methods. This observational, epidemiological, cross-sectional, descriptive study was carried out in the inpatient and ICU settings of an oncological hospital in São Paulo, Brazil. Results. A total of 341 patients who met the inclusion criteria and agreed to participate in the study were interviewed and assessed. Data obtained in the interviews were analyzed for logistic regression analysis. Pressure injury prevalence was 10% (34 patients). The use of disposable diapers was significantly associated with the development of PI, with a 6.077 increased chance of PI in such patients in the ICU setting. In this epidemiologic study of 341 hospitalized cancer patients, the prevalence of PI was 10%. The use of disposable diapers was the only factor associated with the presence of PI after logistic regression analysis. Conclusion. Knowing the risk factors of this specific population was essential to implement actions and optimize indications of disposable diaper use. There is an absence of epidemiologic records due to limited publications available on the subject; creating a program to prevent PI development within the inpatient, assisted population.
MODEL OF INTEGRATED ASSESSMENT OF THE ECONOMIC POTENTIAL OF THE ENTERPRISE
Authors:   Lviv University of Business and Law, Pohrebniak Andrii
Published: November 2022

The object of the research is the peculiarities of the formation, use and improvement of the model of integral assessment of the economic potential of the enterprise in accordance with modern economic conditions and changes. The success of any enterprise in conditions of uncertainty and risk directly depends on various influencing factors and is determined by the potential, the assessment of which is necessary at all levels of preparation and management decision-making, in order to expand the information base within the management system. Practice shows the presence of theoretical and practical problems related to the formation and use of applied mechanisms for assessing the economic potential of enterprises on the basis of operations research and economic diagnostics, and based on the application of economic and mathematical modeling. It is noted that under the economic potential of the enterprise it is appropriate to understand the capabilities, resources, stocks, means of the enterprise that are used and/or can be used to achieve the goals (strategic or tactical) of the enterprise. And the model of integrated evaluation of the efficiency of the use and growth of the enterprise's potential is based on the system of evaluation of the effectiveness of the functioning of its components in the financial-economic, production and commercial sphere, based on parameters (indicators) taking into account priorities, criterion values and the utility function. According to the results of the conducted research, an improved multi-criteria model of the integral assessment of the enterprise potential using the additive utility function is proposed, which, unlike the existing ones, makes it possible not only to calculate the integral indicator of the enterprise potential, to evaluate and monitor the enterprise potential, but also allows to some extent to compare with each other competing enterprises. It is advisable to carry out further research in the direction of determining the ways of effective use and growth of the enterprise's potential.
Investigating Solvent-Induced Aggregation in Edge-functionalized Layered Silicate Clays via All-atom Molecular Dynamics Simulations
Authors: Hill Eric
Published: November 2022

Molecular dynamics simulations can provide the means to visualize and understand the role of intermolecular interactions in the mechanisms involved in molecular aggregation. Along these lines, simulations can allow the study of how surface chemical modifications can influence nanomaterial assembly at the molecular level. Layered silicate clays have been of significant interest for some time, particularly with regard to their use in organic/inorganic nanocomposites. However, despite numerous reports on the covalent linkage of organic moieties via silanol condensation, the theoretical understanding of these systems has heretofore been limited to non-covalent interactions, specifically ionic interactions at the charged basal surfaces. Herein, a model for edge-functionalized layered silicate clays, based on the siloxane linkage, is presented. In addition to reproducing experimentally-observed degrees of molecular aggregation of clay-linked perylene diimide derivatives with different functional terminal groups as a function of solvent composition, a molecular-level understanding of the role of van der Waals interactions and hydrogen bonding of the different end-groups on the aggregation state in different water/DMF mixtures is obtained. The reported model provides a means to simulate organic moieties covalently bound to the layered silicate edge, which will enable future simulations of nanocomposites and organic/inorganic hybrids based on this system.
A Hybrid Machine-Learning Approach to Predict the Iridium-Catalyzed Borylation of C–H Bonds
Authors: Caldeweyher Eike , Elkin Masha , Gheibi Golsa , Johansson Magnus , Sköld Christian , Norrby Per-Ola , Hartwig John
Published: November 2022

The borylation of aryl and heteroaryl C–H bonds is valuable for the site-selective functionalization of C–H bonds in complex molecules. Iridium catalysts ligated by bipyridine ligands catalyze the borylation of the aryl C–H bonds that are most acidic and least sterically hindered, but predicting the site of borylation in molecules containing multiple arenes is difficult. To address this challenge, we report a hybrid computational model that predicts the Site of Borylation (SoBo) in complex molecules. The SoBo model combines density functional theory, semi-empirical quantum mechanics, cheminformatics, linear regression, and machine learning to predict site selectivity and to extrapolate these predictions to new chemical space. Experimental validation of SoBo showed that the model predicts the major site of borylation of pharmaceutical intermediates with higher accuracy than prior machine-learning models or human experts, demonstrating that SoBo will be useful to guide experiments for the borylation of specific C(sp2)–H bonds during pharmaceutical development.
Tilt Corrections for Normal Mode Observations on Ocean Bottom Seismic Data, an example from the PI-LAB experiment
Authors: Harmon Nicholas , Laske Gabi , Crawford Wayne , Rychert Catherine
Published: November 2022

Earth's normal modes are fundamental observations used in global seismic tomography to understand Earth structure. Land seismic station coverage is sufficient to constrain the broadest scale Earth structures. However, 70% of Earth's surface is covered by the oceans, hampering our ability to observe variations in local mode frequencies that contribute to imaging small-scale structures. Broadband ocean bottom seismometers can record spheroidal modes to fill in gaps in global data coverage. Ocean bottom recordings are contaminated by signals from complex interactions between ocean and solid Earth dynamics at normal mode frequencies. We present a method for correcting tilt on broadband ocean bottom seismometers by rotation. The correction improves the ability of some instruments to observe spheroidal modes down to 0S4. We demonstrate this method using 15 broadband ocean bottom seismometers from the PI-LAB array. We measure normal mode peak frequency shifts and compare with 1-D reference mode frequencies and predictions from 3-D global models. Our measurements agree with the 3-D models for modes between 0S14 - 0S37 with small but significant differences. These differences likely reflect real Earth structure. This suggests incorporating ocean bottom normal mode measurements into global inversions will improve models of global seismic velocity structure.

The purpose of the study is to identify the key areas of development of relations between China and Russia as factors of ensuring economic security. The article examines the interaction between Russia and China from the point of view of ensuring economic security in the frame of political instability. The scientific novelty consists in conducting research in this area based on several selected factors: the share of exports and imports in bilateral trade of two countries, their structural features and industry orientation, the impact of the exchange rate on the foreign trade turnover of both countries, the role of the Chinese yuan in the National Welfare Fund of the Russian Federation, the impact of sanctions on the Russian economy since 2014, on the volume of investments; their significance is shown and the impact is justified. The potential of the "One Belt, One Road" strategy implementation and the creation of a Russian-Chinese investment fund is considered. The assessment of investment cooperation showed the main fields of joint development such as the creation of logistics systems and infrastructure, extraction of natural resources, medicine and nuclear energy. In the frame of political instability, China is the largest and most stable foreign economic partner of the Russian Federation; it plays a key role in ensuring economic security.

Цель статьи заключается в исследовании перспектив и разработке рекомендаций для реализации возможностей государственно-частного партнерства на микроуровне инновационной экономики. Статья посвящена разработке нового подхода к развитию инновационной экономики России, отвечающего современным реалиям - обеспечивающего реализацию крупных инновационных проектов, создание и внедрение принципиально новых инноваций, а также раскрытие человеческого потенциала. В основу данного подхода на микроуровне инновационной экономики предлагается заложить государственно-частное партнерство. С опорой на методологию неоинституционализма обосновано, что для реализации институциональных возможностей государственно-частного партнерства на микроуровне инновационной экономики необходимо повышение уровня социальной ответственности бизнеса. Научная новизна полученных результатов состоит в уточнении закономерностей развития инновационной экономики на микроуровне и раскрытии институциональной природы этого процесса за счет возможностей государственно-частного партнерства.

This article is devoted to a new approach development of the innovative economy in Russia meeting modern realities - ensuring the implementation of large innovative projects, creation, and implementation of fundamentally new innovations as well as disclosure of human potential. There is a public-private partnership to be proposed as a base of the new approach at the micro-level of the innovative economy. Based on neo-institutional methodology it is stated in the article that it is necessary to increase corporate social responsibility level in order to implement institutional capabilities of public-private partnership. Research’s originality is in first time revealing the possibilities of public-private partnership at the micro-level of the innovative economy and offering scientific, methodological and practical recommendations for these opportunities’ implementation.

In communication 1, an attempt was made to link the literature data available today on the phylogenetic position of the Baikal seal (Pusa sibirica Gm.) Among the true northern seals (Phocina), the place and time of the origin of its ancestors. Hypotheses about possible ways of penetration of the ancestral form into the lake are critically discussed. Baikal from different sea basins and at different geological times. It is concluded that there is no unequivocal answer to the question about the roots of the Baikal seal (and, therefore, about the ways and time of penetration of its ancestor into Baikal). The ancestral form of the Baikal seal could live in the seas of the Arctic Ocean (Ringed seal Pusa hispida), and in the reservoirs of Paratethys (Caspian seal Pusa caspica), and in the seas of the Far East (Pusa hispida/akiba or Phoca largha). The hypothesis about the relationship of the seal with the ringed seal (Pusa hispida Schreber) is supported and a conclusion is made about the greater probability of the migration of the seal ancestors to Lake Baikal from the Arctic Seas (not earlier than the Pleistocene) using periglacial lakes as intermediate refugia from the advancing ice. The ancestors of the Baikal seal must have had ready-made adaptation mechanisms to the ice conditions of their habitat, which it retained even when living in intermediate reservoirs along the migration routes. It is assumed that the initial number of animals that ended up in Baikal was small (several thousand individuals), and the further evolution of the species took place in an allopatric way. By the time the ancestors of the Baikal seal settled in Baikal, the lake was already a deep-water and cold-water vast reservoir, which it became not earlier than the Pleistocene. The invasion directly into Baikal could have occurred either through the Angara-Yenisei system (subject to an "early" scenario for the emergence of the modern drain), or through the system of the Lena River on glacial lakes in the Vitim River basin and along the Barguzin depression (along the river or bay).

Irrigation of land over time leads to the development of such negative processes as salinization and waterlogging of land, a decrease in soil fertility, a change in the chemical composition of groundwater, soil erosion. The reclamation state of irrigated land is a complex qualitative indicator that assesses the impact of natural and technological factors and characterizes the state of the system «Soils – Soils of the aeration zone – Groundwater». The categories of land reclamation state adopted in Russia and a number of post-Soviet countries determine their suitability for agricultural use and the focus of measures to preserve potential soil fertility. On the example of the Altai Territory, an analysis of the dynamics of a number of indicators characterizing the reclamation state of land is carried out: the depth of the groundwater level; mineralization of groundwater; mineralization of irrigation water; the degree of soil salinization in the root layer; the degree of salinity of the soil, as well as the possible causes of the development of negative processes. Using the methods of mathematical statistics, the rates of development of processes on irrigated lands and trends in increasing / decreasing the area of irrigated agricultural land, on which changes in each of these indicators are recorded, are estimated.

In assessing the hydrodynamic parameters of concrete mixtures placed in monolithic channel linings, the most important point is the development of mathematical models that describe the processes of concrete mixture slippage, taking into account the dynamics of speed reduction and increase in the viscosity of the concrete mixture over time. The main regularities of the hydrodynamic multilayer shear flow of a concrete mixture on the surface of a flat channel slope, where a multilayer plane-parallel viscous flow moves under the action of gravity, are investigated. The boundary value problem of a two-layer flow of a concrete mixture is solved, a system of two layers of viscous incompressible liquids is considered with the properties of each, respectively, the thickness of the bottom and upper layers, taking into account the sliding velocity of particles of a viscous liquid located one above the other. The obtained analytical solution of the problem in the stationary regime of a two-layer shear flow of two different immiscible viscous fluids with different properties makes it possible to formulate the main laws of such flows and describe the processes of sliding of a multilayer concrete mixture, taking into account the dynamics of speed reduction and increase in the viscosity of the concrete mixture over time. A mathematical model has been developed where the dynamic and kinematic structures of a multilayer shear flow in both viscous layers are presented separately.
