From Macro- to Microscale: A combined modelling approach for near-surface wind flow on Mars at sub-dune length-scales
Authors: Love Richard , Jackson Derek W. T. , Michaels Timothy , Smyth Thomas A. G. , Avouac Jean-Philippe , Cooper Andrew
Published: November 2022

The processes that initiate and sustain sediment transport which contribute to the modification of aeolian deposits in Mars’ low-density atmosphere are still not fully understood despite recent atmospheric modelling. However, detailed microscale wind flow modelling, using Computational Fluid Dynamics at a resolution of <2 m, provides insights into the near-surface processes that cannot be modeled using larger-scale atmospheric modeling. Such Computational Fluid Dynamics simulations cannot by themselves account for regional-scale atmospheric circulations or flow modifications induced by regional km-scale topography, although realistic fine-scale mesoscale atmospheric modeling can. Using the output parameters from mesoscale simulations to inform the input conditions for the Computational Fluid Dynamics microscale simulations provides a practical approach to simulate near-surface wind flow and its relationship to very small-scale topographic features on Mars, particularly in areas which lack in situ rover data. This paper sets out a series of integrated techniques to enable a multi-scale modelling approach for surface airflow to derive surface airflow dynamics at a (dune) landform scale using High Resolution Imaging Science Experiment derived topographic data. The work therefore provides a more informed and realistic Computational Fluid Dynamics microscale modelling method, which will provide more detailed insight into the surface wind forcing of aeolian transport patterns on martian surfaces such as dunes.
Robust large-scale clustering based on correntropy
Authors: Jin Guodong , Gao Jing , Tan Lining
Published: November 2022

With the explosive growth of data, how to efficiently cluster large-scale unlabeled data has become an important issue that needs to be solved urgently. Especially in the face of large-scale real-world data, which contains a large number of complex distributions of noises and outliers, the research on robust large-scale real-world data clustering algorithms has become one of the hottest topics. In response to this issue, a robust large-scale clustering algorithm based on correntropy (RLSCC) is proposed in this paper, specifically, k-means is firstly applied to generated pseudo-labels which reduce input data scale of subsequent spectral clustering, then anchor graphs instead of full sample graphs are introduced into spectral clustering to obtain final clustering results based on pseudo-labels which further improve the efficiency. Therefore, RLSCC inherits the advantages of the effectiveness of k-means and spectral clustering while greatly reducing the computational complexity. Furthermore, correntropy is developed to suppress the influence of noises and outlier the real-world data on the robustness of clustering. Finally, extensive experiments were carried out on real-world datasets and noise datasets and the results show that compared with other state-of-the-art algorithms, RLSCC can improve efficiency and robustness greatly while maintaining comparable or even higher clustering effectiveness.

This study aimed to assess the knowledge, practices, and beliefs among the Jordanian population regarding hepatitis B virus (HBV) infection. A cross-sectional questionnaire was designed and used to recruit participants from October 5th through December 12th. Statistical analysis was conducted using SPSS. Descriptive statistical analysis was used to analyse the sociodemographic data, the Shapiro-Wilk test was used to assess the normality, Cronbach’s α was used to evaluate the reliability of the questionnaire and Point-biserial correlation was used to figure out whether there is an association between Score of knowledge and the dichotomous variables. A random sample of 432 participated in the study. The majority were females (n = 310, 71.8%), the mean age was 21 (42.0%) years,416 (96.3%) were urban inhabitants and most of them (n = 351, 81.3%) had bachelor’s degree. School/university (n = 280, 64.8%) were reported as a major source of information followed by TV/internet/social media 276 (63.9%). The total mean (± SD) of knowledge score regarding HBV infection symptoms, transmission modes and treatment was found 12.28 ± 3.2. Participants’ knowledge regarding symptoms including nausea, vomiting and loss of appetite was 73 (16.9%). More than 80% had good knowledge regarding the complications of HBV infection. Only 100 participant reported vaccination (23.1%) against the virus. Poor knowledge and low vaccination rate against HBV were found thus implementing comprehensive educational program for people highlighting the importance of vaccination against the virus is crucial.
Correlates of quality of life among persons living with tuberculosis: A cross-sectional study
Authors: Tornu Eric , Quarcoopome Louisa
Published: November 2022

Introduction

The correlates of quality of life originating from the demographic characteristics, comorbidities and sources of social support among persons living with tuberculosis remain underreported. The aim of this study was to examine the correlates of quality of life among persons living with tuberculosis within Greater Accra, Ghana.

Methods

A cross-sectional survey design was used to assess the correlates of quality of life among 250 randomly sampled persons living with tuberculosis. Quality of life was assessed with the Quality of Life Brief Version (WHOQOL-BREF) questionnaire and correlates were derived using Spearman rho correlations. Chi-square analyses assessed associations among respondent characteristics.

Results

All four quality of life domains (physical, psychological, social relationship and environmental) of persons living with tuberculosis were positively correlated. Furthermore, receiving social support from family or friends correlated positively with respondents’ quality of life. Human Immunodeficiency Virus (HIV) infection and receiving social support mainly from work colleagues or religious institutions correlated negatively with respondents’ quality of life domains. Other correlates of quality of life included age, pleuritis with pleural effusion, number of dependants and distance to tuberculosis treatment centres. Social support from family and friends corresponded with better quality of life among persons living with tuberculosis.

Conclusion

The quality of life domains of persons living with tuberculosis are interrelated and can be enhanced by social support. Healthcare providers should involve the significant others of persons living with tuberculosis, human immunodeficiency virus and pleuritis with pleural effusion in their care to promote patients’ quality of life.

Restoring the ecosystems of the Cerrado biome is challenging considering the diversity of phytophysiognomies present in the biome, some of which are composed of species from different strata (herbaceous, shrubby, and arboreal), which increases the complexity of restructuring the floristic composition. Other factors was involved, such as soil quality, which directly influences the success of restoration, water storage, and nutrients, the financial costs, and a slow ecological process, due to the adverse circumstances found in the area. be restored. The strong anthropogenic interventions by mining processes reduce dramatically the physical and nutritional composition of the soil. We studied two restoration areas in Paracatu, Brazil, to examine their edaphic conditions six years after mining activities ceased and relate them to the status of the restoration process. In 2009, a Cerrado restoration were established in an area previously explored for gravel extraction. Plants were sampled and identified in 11 transects along the planting lines. The diameter base (DB) and total height (HT) were measured. The physical/chemical quality of the soil substrate was determined using a collection of samples in open trenches at four types of points: Cerrado (TC); dead plant pits (TM); seedling pits having living individuals of the most abundant species (TT); and those of the second-most abundant species (TE). Cecropia pachystachya Trécul and Tapirira guianensis Aubl. were most abundant and demonstrated the potential to thrive in areas degraded by mining having low mortality rates and growth at relatively DB and HT. The physical quality indicators in the gravel pits were not limiting, indicating that substrate preparation was efficient in this regard. The organic matter content in TM, TT, and TE was low in comparison to that of TC, and the chemical conditions in the TE pit substrates were similar to those in TM pits, suggesting C. pachystachya is a species with good plasticity, whereas T. guianensis is present in pits with higher levels of phosphorus.

Published: November 2022

Peripherally inserted central catheters (PICCs) are prevalent devices for medium-to-long-term intravenous therapy but are often associated with morbid and potentially lethal complications. This multi-center study sought to identify barriers and facilitators of implementing evidence-based appropriateness criteria to improve PICC safety and patient outcomes in a pay-for-performance model. Participating hospitals received an online toolkit with five recommendations: establishing a vascular access committee; implementing a clinical decision tool for PICC appropriateness; avoiding short-term PICC use (≤5 days); increasing use of single-lumen PICCs; and avoiding PICC placement in patients with chronic kidney disease. Longitudinal online surveys conducted biannually October 2014–November 2018 tracked implementation efforts. A total of 306 unique surveys from 34 hospitals were completed. The proportion of hospitals with a dedicated committee overseeing PICC appropriateness increased from 53% to 97%. Overall, 94% of hospitals implemented an initiative to reduce short-term and multi-lumen PICC use, and 91% integrated kidney function into PICC placement decisions. Barriers to implementation included: achieving agreement from diverse disciplines, competing hospital priorities, and delays in modifying electronic systems to enable appropriate PICC ordering. Provision of quarterly benchmarking reports, a decision algorithm, access to an online toolkit, and presence of local champion support were cited as crucial in improving practice. Structured quality improvement efforts including a multidisciplinary vascular access committee, clear targets, local champions, and support from an online education toolkit have led to sustained PICC appropriateness and improved patient safety.

Adaptação do HCM para análise de rodovias de pista simples sem faixas adicionais no Brasil
Authors: Sangi de Oliveira Juliangelo Kayo , Bessa Júnior José Elievam
Published: November 2022

O Highway Capacity Manual (HCM) é o principal documento utilizado para a análise do nível de serviço e da capacidade de componentes rodoviários. Todavia, a aplicação de sua metodologia sem que sejam realizadas adaptações às condições locais de tráfego e das vias e às características dos veículos e dos motoristas pode resultar em discrepâncias entre as medidas de desempenho calculadas por meio do manual e as observadas em campo. Este trabalho teve como objetivo adaptar o novo método do HCM (7ª edição) às condições das rodovias de pista simples brasileiras sem faixas adicionais. De posse de uma versão recalibrada do Aimsun Next, foram gerados resultados de simulação para segmentos hipotéticos com o intuito de ajustar modelos de tráfego para obter a densidade de veículos em pelotões (FD), a nova medida de serviço proposta para avaliar segmentos de rodovias de pista simples. Os resultados de FD encontrados com o método proposto mostraram que os modelos de tráfego do HCM necessitam de adaptações para avaliar rodovias brasileiras, evitando-se níveis de serviço subestimados em relação ao que é observado em campo.
The Quest for Self-Determination and the State in Ethiopia: The Oromo Popular Uprising of 2014–2017 in Historical Perspective
Authors: Dinka Etana H.
Published: November 2022

This article seeks to place the Oromo popular uprising of 2014–2017 into a deeper historical context. It traces the origins of the uprising through various landmarks in the Oromo national struggle for self-determination and turning points in the history of Ethiopia's state-making projects. In understanding the relationship between attempts at state construction and the determined opposition it encountered, the article emphasizes the dramatic changes that unfolded between the close of the nineteenth century and the political transition that was triggered in 2018. Although recognizing Ethiopia's long-ranging political intricacies, this article argues that the Oromo popular uprising of 2014-17 demonstrates the peak of decades of struggles for inclusion, recognition, self-rule, and equality that have mainly resulted from the Ethiopian state's cyclical violence and rejection of demands for reform.
La donación sin fenómenos de Jean-Luc Marion
Authors: Cazzanelli Stefano
Published: November 2022

El objetivo del presente artículo es analizar la fenomenología de la donación de Jean- Luc Marion y plantear algunas críticas de carácter fenomenológico-hermenéutico. En primer lugar, se quiere mostrar cómo las interpretaciones que el pensador francés elabora de la donación en el «primer Heidegger» están claramente influenciadas por la filosofía del así llamado «segundo Heidegger» y, por tanto, pierden de vista el trasfondo hermenéutico que anima toda investigación heideggeriana de la década de 1920. En segundo lugar, se pondrá de manifiesto cómo una fenomenología de la donación que reconduzca toda manifestación al puro darse de los fenómenos responde más a una problemática de carácter teorético-metafísico que a un planteamiento propiamente fenomenológico o hermenéutico.
Analisis Prakiraan Kebutuhan Energi Nasional Jangka Panjang Untuk Mendukung Program Peta Jalan Transisi Energi Menuju Karbon Netral
Authors: Yudiartono Yudiartono , Windarta Jaka , Adiarso Adiarso
Published: November 2022

Berdasarkan peta jalan transisi energi, strategi utama yang disusun Pemerintah untuk menuju karbon netral di sisi kebutuhan energi adalah pemanfaatan kompor induksi dan pengembangan jaringan gas perkotaan di sektor Rumah Tangga serta penerapan kendaraan bermotor listrik berbasis baterai (KBLBB) untuk sektor transportasi. Selama periode 2020-2050, laju pertumbuhan PDB rata-rata sebesar 5,03% per tahun dan pertumbuhan penduduk sebesar 0,63% per tahun, mengakibatkan total kebutuhan energi final (tanpa biomasa ) untuk skenario BAU meningkat dari 845 juta SBM pada tahun 2020 menjadi 2.889 juta SBM pada tahun 2050 atau meningkat rata-rata sebesar 4,2% per tahun. Sedangkan untuk skenario transisi energi (TE), kebutuhan energi final tersebut hanya tumbuh sebesar 3,8% per tahun, atau naik menjadi hanya 2.593 juta SBM pada tahun 2050. Terlihat bahwa terjadi penurunan sekitar 10% pada total kebutuhan energi final, apabila dibandingkan dengan skenario BAU. Hal ini terjadi karena efisiensi kompor induksi dan kompor berbahan bakar gas jauh lebih efisien apabila dibandingkan efisiensi kompor LPG, karena itu akan menurunkan konsumsi LPG secara signifikan, yaitu sebesar 10,12 juta ton per tahun. Disamping itu percepatan penerapan program KBLBB di sektor transportasi juga akan menghemat penggunaan BBM secara signifikan bila diterapkan secara konsisten, dimana pada tahun 2050 tersebut terjadi penghematan kebutuhan bensin dan solar berturut turut sebesar 68 juta kilo liter dan 2,7 juta kilo liter. Di sisi lain, pada tahun yang sama, diprediksi akan terjadi kenaikan kebutuhan listrik untuk sektor transportasi dan sektor rumah tangga, berturut turut mencapai 232 TWh dan 74 TWh.

Does online engagement matter? The impact of interactive learning modules and synchronous class attendance on student achievement in an immersive delivery model
Authors: Goode Elizabeth , Nieuwoudt Johanna , Roche Thomas
Published: November 2022

One Australian public university is radically changing the way it delivers higher education, introducing a 6-week immersive scheduling delivery model across all units and courses. Despite the emerging success of block and immersive models for raising the performance of diverse student cohorts, the design factors underpinning positive outcomes are underexplored. This paper presents a mixed methods study of the impact and value of student engagement with interactive and responsive online content modules and synchronous classes in an immersive scheduling model. The findings indicate that behavioural engagement with online learning modules has a positive effect on academic success and is a significant predictor of a higher final score. Qualitative data indicate several attributes of high-quality online learning modules that students appear to associate with engagement and deeper learning in the immersive model: interactivity, media richness, constructive alignment, flexibility and responsiveness. Synchronous class attendance did not impact final scores; however, students nonetheless valued the opportunity to form safe and supportive communities of inquiry during classes. This study demonstrates that in times of increasing demand for more flexible learning, immersive scheduling models that are founded on active learning principles and embed interactive, responsive, media-rich online learning modules can improve student engagement and performance.
Implications for practice or policy:

Higher education practitioners should integrate interactive, responsive, media-rich and constructively aligned online learning modules into curricula.
Synchronous active learning classes that create safe communities of inquiry should be offered alongside options for asynchronous participation.
Low levels of engagement with online learning modules should prompt follow-up from educators to raise engagement and bolster academic achievement.
Immersive delivery models are effective curriculum innovations that, when designed with interactive online modules, can support improved academic achievement.

Mobile learning is well established in literature and practice, but under-evolved from a rigorous learning design perspective. Activity theory presents a sophisticated way of mapping and understanding learning design, but for mobile learning this does not always translate into change in practice. The reported research addresses this by coupling a mobile learning specific approach to activity theory with a practice-based framework: the design for transformative mobile learning framework mapped to the pedagogy-andragogy-heutagogy continuum matrix (the DTML-PAH Matrix). Seven case studies are analysed using this approach and presented narratively along with framework informed analysis. Findings include that the DTML-PAH Matrix can be used to provide clearer implications and guidance for mobile learning practice, and that the DTML-PAH Matrix can also be guided by the practice over time. Implications for further research and practice are discussed.
Implications for practice or policy:

Provide technological and pedagogical scaffolds to students.
Learning designs should focus upon enabling elements of learner agency and creativity.
To develop learning solutions to real world problems utilise a design-based research approach.
Create authentic collaborative learning activities and tasks.
Integrate mobile learning affordances in the design of the course and curriculum.
Prawo podmiotowe Etyka – prawo – polityka
Authors: Raburski Tomasz
Published: November 2022

The book explores the concept of rights in three fields: law, morality, and politics. Rights are treated as a bridge-concept, connecting those fields. The work draws heavily on English-, German- and Polish-language sources. The differences between those academic discourses on rights, Rechte and prawa are discussed. The introductory chapter examines the meaning of the concept, and the variety in the forms of rights. The differences between the English concept of right and the Polish prawo podmiotowe are discussed. The first chapter presents the moral aspect of rights, i.e. the features of the language of rights in comparison to other moral languages, and the role of rights in contemporary ethical theories (esp. utilitarianism). The second chapter examines legal rights. The German concept of Reflexrecht is described. Two forms of legal institutions are compared: one based on rights and the other on well-being. Legislators have to choose which form they use when they enact the law. Several examples are analyzed – what are the consequences of such choices and what are guiding principles helping the legislators to make them. In the third chapter, the politics of rights is discussed, and its three forms are examined in detail: strategic litigation, strengthening of democratic principles, and the empowerment of social movements. The book concludes with a historical chapter, outlining common mistakes about the evolution of rights and their historical role. Two historical moments are discussed in more detail: the conflict of intellectual traditions in 19th century Polish political discourse, and the Marxist critique of rights in socialist legal systems, which led to attempts to replace rights with other institutional forms.
Performance tests of geodetic receivers with tilt sensors in obstructed environments using the NRTK GNSS technique

Published: November 2022

The Department of Lands (DOL), Thailand, has adopted the Network-based Real-Time Kinematic (NRTK) Global Navigation Satellite System (GNSS) surveying technique using a Virtual Reference Station (VRS) to support cadastral surveys since 2011. Determining accurate coordinates of parcel boundary markers at building corners or near fences and walls is difficult because a GNSS range pole cannot be leveled with a circular bubble. This study aims to evaluate the performance of the receivers equipped with tilt sensors for horizontal and vertical positioning. Two types of tilt sensors used for evaluation were a magnetometer and micro-electro-mechanical system (MEMS) and an inertial measurement unit (IMU). Conducting the NRTK GNSS surveying tests was based on the pole tilt angles of 0°, 15°, 25°, 35°, and 45° from a plumb line in controlled and obstructed environments. The IMU-based tilt sensor had more advantage of accurately positioning over the MEMS sensor. The results showed that using the IMU, better than 4 cm horizontal positioning accuracy was achievable when the pole was tilted by 15° or less under non-multipath and open-sky conditions. The vertical accuracy was of a few centimeter levels and least sensitive to tilt angles using either type of sensor. However, none of the sensors precisely compensated for pole tilt in strong-multipath and complex environments, causing increased horizontal errors in decimeter levels.
Evaluation of the wettability of prepared anti-wetting nanocoating on different construction surfaces
Authors: Omar Mustafa H. , Hussian Wissam A. , Ahmed Mays A.
Published: November 2022

Generally, the major problems of moisture damage are caused by wetting, and particularly in construction, which has led to extensive research for the production of hydrophobic (anti-wetting) coatings. The aim of this research is to prepare an anti-wetting (hydrophobic) nanocomposite coating for different construction surfaces (ceramic, brick and gypsum). Hydrophobic nanocomposite coating was synthesized using electrospinning technique. Polymethyl methacrylate and polystyrene (PS) solutions were prepared in different ratios and then separately reinforced with ZrO2 and ZnO nanoparticles. Contact angle, surface roughness, surface free energy and weathering effects were calculated for all specimens after being coated. All previously selected materials surfaces showed superhydrophobic and hydrophobic properties. The best results were obtained on ceramic surfaces after coating with PS/ZrO2. The water contact angle was 153° while the surface roughness was 0.491 µm and also showed the lowest surface free energy which was 5.5 mJ/m2. Weathering conditions tend to decrease the values of contact angle and this is due to the environmental effect of the weathering but they still have their hydrophobic properties. SEM test was used to determine the surface morphology and nanoparticle size for ceramic surfaces coated with PS and nano-ZrO2.

Published: November 2022

This meta-analysis aimed to investigate the correlation between early-life antibiotic use and allergic rhinitis. PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases were searched for available studies. Eighteen studies covering 1,768,874 children were included. Early-life antibiotics were associated with an increased incidence of allergic rhinitis (effect size (ES) = 5.00, 95% confidence interval [CI]: 4.88–5.13; I
2 = 95.7%, P
heterogeneity <0.001). In Asia, Europe, and the USA, the incidence of allergic rhinitis in the antibiotic group was higher than that in the no medication group (Asia: ES = 3.68, 95% CI: 3.38–4.01; Europe: ES = 3.20, 95% CI: 3.00–3.42; USA: ES = 3.68, 95% CI: 2.74–4.95). Compared with the no medication group, children who received antibiotics in the first 1 week of life (ES = 5.75, 95% CI: 2.18–15.18), first 1 year of life (ES = 3.37, 95% CI: 3.20–3.55; I
2 = 64.2%, P
heterogeneity = 0.001), or first 3 years of life (ES = 5.21, 95% CI: 2.42–11.19) had a higher incidence of allergic rhinitis. No individual study influenced the estimates of the meta-analysis. The funnel plot showed moderate symmetry and low publication bias. In conclusion, the use of antibiotics in early life was associated with allergic rhinitis. Still, most included studies analyzed antibiotic exposure as a dichotomous variable, without information on the type and dosage of antibiotics.

Published: November 2022

The optimization of the fluorescence enhancement factor of the IgG-FITC conjugate as an immunofluorescent marker, depending on the optical and topographic parameters of the colloidal silver film on the surface of a polystyrene plate for immunoassay, was carried out for the first time, and the factors effecting the enhancement were identified. By means of time-resolved spectroscopy as well as by detection the relative concentrations of IgG-FITC adsorbed on the solid phase with enzyme-linked immunoassay, it was shown that fluorescence enhancement in the presence of silver nanoparticles is a resonance process associated with plasmon effects. The most important parameters correlating with the fluorescence enhancement factor are the optical density value at the wavelength of excitation and emission of the fluorophore. The maximum enhancement factor of 10.2 times was obtained for Ag films with the highest optical density.
A short survey of key silage-making practices on Northern Ireland dairy farms, and farmer perceptions of factors influencing silage quality
Authors: Ferris C.P. , Laidlaw A.S. , Wylie A.R.G.
Published: November 2022

Northern Ireland dairy farmers (n = 174) were surveyed to identify key silage-making practices, and factors perceived to influence the quality of grass silage made on their farms. The majority of farmers (65%) harvested grass for silage three times/year: 62% normally used a contractor, while 47% routinely used a silage additive. Delays to mowing and delays to harvesting due to adverse weather or poor ground conditions were perceived to have a large or very large impact on silage quality (68% and 53% of farmers, respectively). Inadequate wilting, poor-quality swards on owned land, on rented land and “contamination” of first-cut grass with autumn or winter growth herbage were all perceived as having a large or very large impact on silage quality (32%, 27%, 40%, 30% of farmers, respectively). Over the previous decade, 11%, 41% and 37% of farmers claimed a small, moderate or large improvement in silage quality, mainly due to earlier cutting of grass and ensiling better quality swards.
Mathematical and information models of decision support systems for explosion protection
Authors: Volkov Viсtor E.
Published: November 2022

This paper is dedicated to the issue of mathematical and information modeling of the combustion-to-explosion transition that makes it possible to create an adequate mathematical and information support for decision support systems (DSS) for automatedcontrol of explosive objects.A simple mathematical model for the transition of combustion to explosion is constructed. This model is based on solving mathematical problems of the hydrodynamic stability of flames and detonation waves. These problems are reduced to solving eigenvalue problems for linearized differential equations of gas dynamics. Mathematical model is universal enough. It provides opportunities for making simple analytical estimates for the explosive induction distance and the time of the shock wave formation. The possibilities of the transition of slow combustion to both a deflagration explosion and a detonation wave are considered. Theoretical estimates of the explosive induction distance and the time of the combustion-to-explosion transition are obtained. These estimates are expressed by algebraic a formula, the use of which save computer resources and does not require significant computer time. The application of fuzzy logic makes it possible to use the proposed mathematical model of the combustion-to-explosion transition for real potentially explosive objects in industry and transport.Mathematical models of potentially explosive objects are based on combination of the fuzzy logic and classical mathematical methods. These models give possibilities for creating corresponding information models. Thus mathematical and information support of DSS for automated control systems of explosive objects is developed. The main advantage of these DSS is that it makes it possible for decision makers to do without experts. In particular, developed mathematical and information models create the base forsoftware of DSS for explosion safety of grain elevators. Appropriate software is developed and some calculations are performed. These calculations are useful not only from the point of view of testing the proposed method of mathematical modeling of a grain elevator as a potentially explosive object or testing the software itself, but also from the point of view of the grain elevator designing.

Published: November 2022

The effective work of housing and utility service providers is closely related to the development projects they implement. Anti-risk management is an important component of development project management. The analysis of mathematical, functional,and informational models of management of development projects of providers of housing and communal services, takinginto account risks, was carried out. Mechanisms for integral evaluation of projects, priority allocation of company resources in the most promising directions are proposed. The limitations of the development projects of housing and utility service providers for further scientific research are indicated. An essential lever for increasing the effectiveness of anti-risk management in the development projects of providers of housing and communal services is the possibility of adjusting priorities regarding the implementation of development projects in real time due to the introduction of management automation and decision-making algorithmization, a process approach to risk management and management decision-making, and a dynamic organizational structure of project management development Automation of management and algorithmization of management decision-making allows all participants of development projects to be in one information system: to build a logical sequence of tasks, to determine the project path, to create an uninterrupted material flow with the minimization of necessary stocks, to establish transparency and control for stakeholders of development projects, etc. Algorithmization of decision-making allows timely prevention of project volume growth, low productivity, cost overruns, lack of timeandresources, decision-making based on incomplete information, incompetence of development project participants. The dy-namic organizational structure of management of development projects stimulates the coordination of actions and quick resolution of issues, education of the personnel reserve, establishment of communication, etc.

Chat bots are web-based systems that have recently received a lot of attention due to their ability to provide professional financial advice at a lower cost than a human advisor. We considered anthropomorphic design of chat bot as a positive impact on human perception, which is an important factor in human-computer interaction, because increasing the level of anthropomorphism of the system can potentially compensate for the lack of contact with a person. The influenceof the anthropomorphism effect and anthropomorphic design of the bot on the feeling of social presence, trust, and the desire to follow recommendations are investigated.High cost of financial advice, the volatility of markets and problems with finding professional financial advisors have created favourable conditions for the use of robo-advisors. Due to the growing popularity ofrobo-advisors andchat bots, new opportunities appeared for banks for attracting new customers. There are a large number of chat bots that can provide financial advice, butusually, these are complex solutions and they require quite a lot of time to work with them, so if the user's goal is to get a quick and specific answer, such solutions are not the best option.The goal of our research is to develop a Telegram chat bot for personalized financial advice. To meet this goal we need consider examples of chat bots advisors for potential investorsto analyse available software solutions for financial advisors and create our own software product for personalized financial advice.Research methods includeanalytical mathematical methods and technologies, such as Python, Telegram Bot API, Aiogram, Docker, Amazon Web Services, EC2, and UbuntuServer. We created our own software product, a telegram bot for automated financial consultations to achieve the goals of private investors by calculating constant level of consumption during determined periodunder expected inflation rate to decide whether invest or not. Our telegram bot provides option for receiving financial advice and helping potential investors with capital distribution.

Social capital can strengthen social potential in developing various aspects, including local tourism. Regarding the development of local tourism, social capital is described through 2 dimensions: bonds, and bridges (association). Bonding social capital is understood as close kinship capital (family environment to peers). Bridging social capital (association) is described as the capital of relatively distant kinship (coworkers and colleagues). This article describes the relationship between social capital, bonds, and bridges related to local tourism development. The research was conducted in Kampung Hijau Banjarmasin. The results show that the social capital of bonds and bridges, rooted in religious values and inherited through family parenting, play important roles in nurturing caring personality towards the environment. As a result, residential areas along river banks that were formerly slums become organized and healthy spaces.

This paper is a first attempt to provide an overview of the main lexicographic works of the most spoken Angolan languages of African origin, which were written by missionaries of Portuguese Patronage and laymen who were living in the current territory of Angola (western Africa), from the beginning of Portuguese colonization until its independence in 1975. The current Republic of Angola encompasses old African kingdoms, specifically those of Kongo, Lunda, Matamba, Ngola-Ndongo, and Benguela, and has almost 50 African languages, but Portuguese is the only official language. The Angolan languages of African origin most studied and described by the Portuguese were initially Kimbundu, and, more recently, Umbundu and Nyaneka. The first dictionary of a Bantu language was written in mid-1648 by Italian and Spanish Capuchins led by the Portuguese–Congolese mestizo secular priest Manuel de Roboredo (later, Francisco de São Salvador, O. F. M. Cap., d. 1665). However, the regular linguistic description of the Angolan languages was initiated at the beginning of the 19th century by the Italian Bernardo Maria [Cassaro] da Canicattì, O. F. M. Cap. (1749–1834). In addition, after the “re-establishment” (which was never officially assumed) of the religious orders in Portugal (ca. 1870), the Portuguese Province of the Congregatio Sancti Spiritus (C.S.Sp.) [Congregation of the Holy Spirit] was formed in 1867 mainly because of the evangelization of Angola. In point of fact, the most relevant dictionaries of the Angolan languages in the 20th century were written by the Holy Ghost Fathers [João] Albino Alves [Manso] (1908–1956) (Kimbundu, 1951), António Joaquim da Silva (1909–1995) (Nyaneka, 1966), and José Francisco Valente (1912–1993) (Umbundu, 1972). There are also relevant lexicographic works by laymen, such as the Brazilian Doctor Saturnino de Souza e Oliveira (1820–1871), the Angolan poet, writer, and journalist Joaquim Dias Cordeiro da Matta (1857–1894) for Kimbundu, and the Portuguese medical officer José Pereira do Nascimento (1861–1913) for Umbundu.

The paper is devoted to the development of a catalyst for the synthesis of the higher hydrocarbons from carbon dioxide and hydrogen. The conversion of greenhouse gas CO2 into value-added chemicals contributes not only to sol-ving environmental problems, but also to obtaining valuable fuel. Catalysts that are active in the hydrogenation reaction of CO are also active in the process of CO2 hydrogenation. The most active catalysts in the hydrogenation of carbon dioxide are based on transition metals, in the presence of which mainly methane and a small amount of carbon monoxide are formed. Investigation of the kinetics of hydrocarbons synthesis by hydrogenation of carbon dioxide in the presence of transition metals allowed establishing the mechanism of the process and no perspective of such catalytic systems for hydrocarbons synthesis via intermediate formation of carbon monoxide. It is established that the optimal method of synthesis of higher hydrocarbons is the indirect path, through the intermediate formation of methanol with its further dehydration. The synthesis of methanol from gas mixtures of H2, CO, and CO2 with different composition in the presence of industrial catalysts takes place along the same macroscopic route, by reducing CO2, and is accompanied by a reverse water-gas shift reaction. Therefore, gas mixtures of different composition can be used as raw material for methanol production. Based on our own and literature data, the general peculiarities of the carbon dioxide hydrogenation reaction were obtained, which allowed developing a complex multifunctional catalyst for the synthesis of higher hydrocarbons from carbon dioxide and hydrogen. The proposed catalyst combines the properties of ones for the synthesis of oxygenates from carbon dioxide, and catalysts for the processes of hydrocarbons synthesis from me-thanol and other alcohols. The synthesis of higher hydrocarbons with a predominant content of branched hydrocarbons on the developed bifunctional catalyst was carried out and the optimal conditions for the process were determined.

In this work we aim for developing a kinetic model for the methyl methacrylate and methacrylic acid synthesis by the combined condensation and esterification of methyl propionate and propionic acid with formaldehyde and methanol in the presence of the silica-supported boron-phosphorus-oxide catalyst promoted by oxides of tungsten and zirconium. The dependencies of the formation rates of methyl methacrylate, methacrylic acid and diethyl ketone from the concentrations of methyl propionate, propionic acid, formaldehyde and methanol were studied, and reaction orders of every product formation with respect to each reagent were determined. Methacrylic acid is formed predominantly by condensation of methyl propionate with formaldehyde, and methyl methacrylate hydrolysis is insignificantly. The methyl methacrylate formation reaction rate is limited by the methyl propionate adsorption rate on the catalyst surface, and both reactions of methyl methacrylate and methacrylic acid formation are inhibited due to adsorption of formaldehyde, propionic acid and methanol. Based on obtained data, the reaction scheme was offered, which includes formation of intermediates such as 3-hydroxy-2-methylpropanoic acid, its methyl ester and 3,3-dihydroxy-2-methylpentanoic acid. From this reaction scheme the kinetic model was derived using steady state approximation. The reaction rate constants and their activation energies for this model were calculated from experimental data. Validity of the model was experimentally confirmed by the correlation between experimental and theoretically calculated data. Therefore, the developed kinetic model satisfactorily describes the process of the combined condensation and esterification of methyl propionate and propionic acid with formaldehyde and methanol as well as partial cases of condensation of methyl propionate with formaldehyde and propionic acid with formaldehyde, and is suitable for process optimization and technological calculations.
