Abstract. Haile AA. 2022. Ethnobotanical study of medicinal plants used by local people of Mojana Wadera Woreda, North Shewa Zone, Amhara Region, Ethiopia. Asian J Ethnobiol 5: 35-43. This study was conducted in Mojana Wadera Woreda of North Shewa Zone (Ethiopia) to document the indigenous knowledge of local communities on medicinal plants. The data was collected using structured and semistructured interviews with herbalists. Information on medicinal plants was collected from June 2020 to October 2020. Fourteen (10 males and 4 females) key informants were deliberately selected during the data collection, but no group discussion was conducted due to the coronavirus epidemic. Descriptive statists (percentage and frequency) were used to summarize ethnobotanical data and preference ranking, and the Information consensus factor (ICF) was also included. A total of 56 medicinal plants from 52 genera, and 38 families, were identified in the study area, where they were used to treat human and animal diseases. Family-wise, Asteraceae was the most dominant family, followed by Lamiaceae. Herbs were the most dominant growth forms as they accounted for about 29 (52.72%) species, while shrubs had 17 (30.9%) species. Most herbal remedies were prepared by mixing 25.45% of the roots and leaves. The preparation was usually done by crushing to 45.45%, and during the preparation, the herbs were usually fresh. Most medicines were administered orally to the sick. According to the key informant's response, the plants in the study area are under threat. Therefore, the conservation of medicinal plants related to indigenous knowledge is important for future generations.

Abstract. Das G, Thou K, Mondal P, Meeran SM. 2022. Review: Ethnomedicinal plants used for wound healing and dermatological problem in the North-Eastern Hill Region of India. Asian J Ethnobiol 5: 102-119. Wound healing is a complex process that facilitates tissue cohesion and homeostasis renewal. Medicinal plants have several bioactive compounds and play a principal role in healing and curing human and animal diseases. In our review, we collected ethnobotanical information mostly from Nagaland, a North-Eastern state of India, from various ethnic groups through personal communication, articles, surveys, and sources. In this study, we selected 26 plant species belonging to 20 families categorized as herbs (15 species), shrubs (5 species), trees (4 species), and climbers (2 species) with scientifically demonstrated medicinal properties or reported from ethnic groups on wound healing, dermatological problem, other numerous diseases and disorders relating to the urinary system, inflammation, tumors, diabetes, diarrhea, gastritis, scabies, skin sores, animal/insect bites, parasitic related problems, and rheumatism. They have been compiled and reviewed. Medicinal plants are considered efficacious adjuvants or alternatives to conventional therapies to treat various diseases, and the use of medicinal plants and their products to cure different ailments was reported and recorded. Our review will help create awareness about using medicinal plants and alternative medicine to ameliorate dermatological problems and treat various diseases in humans and animals.

Abstract. Cahyaningsih AP, Arifiani KN, Aprilia D, Nugroho ME, Setyawan AD. 2022. Ethnobotanical study of the non-medicinal plant by village communities in the karst area of Pacitan, East Java, Indonesia. Intl J Trop Drylands 6: 1-10. The local community of Pacitan District, especially in the karst area in several villages of Tulakan Sub-district, has a yard and farm usually planted with many species of plants that have various benefits. These plants are edible, animal feed, spices, biopesticides, and plant growth hormones. However, the knowledge of the local community of Tulakan Sub-district regarding the various benefits of plants is only known from generation to generation, conveyed orally and in daily practice habits, so a study is needed to document this information. This study aims to reveal the knowledge of local communities and the diversity of non-medicinal plant species to meet communities' daily lives. The location of research was carried out in 2 villages located in Tulakan Sub-district, Pacitan District, East Java, Indonesia, namely Bungur Village and Tulakan Village. Data was collected through field surveys and direct interviews using the snowball sampling technique. A total of 40 respondents were interviewed, with details 14 male and 26 female. Respondents with the majority of high school educational backgrounds have around 46-55 years old. The inventory of non-medicinal plants amounted to 60 species of angiosperm plants from 43 families. The plants used consisted of 34 species for the edible plants, 20 species for the fodder plants, 6 species for herbs, 1 species used for biopesticide, and 1 species used for natural growth hormone. Based on the study results, it is known that local people use plants as an edible plants with more diverse plant species compared to other uses.
Co-creation for Transformative Innovation Policy: an implementation case for projects structured as portfolio of knowledge services
Authors: Palavicino Carla Alvial , Matti Cristian , Brodnik Christoph
Published: January 2023

Background:

Transformative Innovation Policy (TIP) encompasses a variety of policy frameworks that seek to use the potential of science, technology, and innovation to address societal challenges. To do so, it relies on inclusive co-creation processes for the design, implementation and evaluation programmes and policies that can drive systemic transformation towards sustainability.

Aims and objectives:

To date there are few empirical studies available on how this co-creation approach can be implemented at the level of programmes and projects working on transformative innovation, and what specific competences, processes and functions are required for the successful implementation of this framework. This paper seeks to provide empirical evidence on how to implement TIP at the project level.

Key conclusions:

This paper shows the importance of adaptability and modularity of processes that are used to translate the TIP framework to a specific context, allowing and encouraging processes of adaptation by project partners and other stakeholders. Secondly, we highlight how knowledge services can be used to translate and negotiate meaning for complex frameworks, resulting in the production of new knowledge that is not only contextually relevant, but that feeds into a larger pool of evidence of how theories apply to real-world cases. Thirdly, it highlights the importance of building teams with skills such as facilitation, brokering, communication, translation and embedding of science-based concepts and frameworks, and the ability to lead processes of co-design that ensure coherence across different interventions while being adaptable to varied project contexts.

Published: January 2023

This research reports an advancement in splicing silica glass fiber to
sapphire single-crystal optical fiber (SCF) using a specialized glass
processing device, including data that demonstrate the thermal
stability of the splice to 1000°C. A filament heating process was used
to produce a robust splice between the dissimilar fibers. A
femtosecond laser is used to inscribe a fiber Bragg gratings sensor
into the SCF to measure the high-temperature capabilities and signal
attenuation characteristics of the splice joint. The experimental
results demonstrate that the proposed splicing method produces a
splice joint that is robust, stable, repeatable, and withstands
temperatures up to 1000°C with a low attenuation of 0.5 dB. The
proposed method allows placement of SCF-based sensors in the extreme
environments encountered in various engineering fields, such as
nuclear, chemical, aviation, and metals manufacturing, to enable
improvements in process monitoring, product quality, and production
efficiency.
Current knowledge about early childhood caries in the gulf cooperation council with worldwide reflection: Scoping review of the scientific literature (2010–2021)
Authors: Alkhtib Asmaa Othman , Mohamed Hasaan G.
Published: January 2023

Early childhood caries (ECC) is one of the most prevalent chronic childhood diseases affecting the primary teeth of children younger than 6 years of age. The disease etiology is complex and includes social, biological, and dietary factors. This review aims to explore the knowledge of ECC prevalence globally and locally within the Gulf Cooperation Council (GCC) countries during the years 2010–2021. Another aim is to explore oral health promotion programs with more focus on the GCC region. A search was conducted in PubMed, Medline, Scopus, the Cochrane Collaboration database, and Google Scholar to identify relevant studies published between 2010 and 2021 using specific keywords. Studies that utilized both the World Health Organization criteria and International Caries Detection and Assessment System for dental caries assessment were included. The included studies indicated considerable variation in the reported prevalence of ECC. While developed countries show low prevalence, countries in the GCC and other Arab countries show a high prevalence of ECC. Many oral health promotion programs were identified globally including oral health education, nutritional programs, the use of fluoride and pit-and-fissure sealants, and inter-professional population-based oral health promotion and prevention programs such as school-based oral health programs, motivational interviewing, and anticipatory guidance. ECC remains a significant problem in many parts of the world including the GCC region. Oral health prevention programs have been established within the GCC region. Nevertheless, the GCC region has some unique characteristics that need to be investigated to contextualize the western model of the dynamics of ECC prevention and promotion programs locally.

Published: January 2023

Physical inactivity is a major risk-factor of non-communicable diseases. The World Health Organization has set physical activity recommendations for adults to reduce physical inactivity and its consequences. However, 1.4 billion adults are non-adherent to the recommendation worldwide. The prevalence of non-adherence to this recommendation and its predictors has not been assessed in urban Ethiopia. This study aimed to determine the prevalence of non-adherence to physical activity recommendations and identify its associated factors among healthy adults in urban centers of Southwest Ethiopia. A community-based cross-sectional study was employed from May to June 2021, involving 1191 adults in urban centers of Southwest Ethiopia. Data was collected using Global Physical Activity Questionnaire. Multivariable logistic regression was used to identify factors associated with non-adherence to physical activity recommendations using 95% confidence interval of adjusted odds ratio at P-value of < 0.05.Overall, 61.2% of participants were non-adherent to physical activity recommendations. Older age (AOR = 6.6; 95%CI (2.3–19)), female sex (AOR = 6.1; 95%CI (3.5–10.5)), lower educational status (AOR = 0.5; 95%CI (.28–0.93)), less community engagement (AOR = 2.7;95% CI (1.3–5.5)), lower level of happiness (AOR = 4.7; 95%CI (1.3–16.8)) and physical inactivity of family members (AOR = 2.5; 95%CI (1.4–4.3)) were associated with non-adherence. The prevalence of non-adherence to physical activity recommendations in the study area is high. Age, sex, educational status, community engagement, level of happiness and physical inactivity of family members were predictors of non-adherence to the recommendations. Interventions have to target females and older adults. Community participation and family based physical activity have to be advocated to avert the consequences of physical inactivity.
Exploring potential risk pathways with high risk groups for urban Rift Valley fever virus introduction, transmission, and persistence in two urban centers of Kenya

Published: January 2023

Rift Valley fever virus (RVFV) is a zoonotic arbovirus that has profound impact on domestic ruminants and can also be transmitted to humans via infected animal secretions. Urban areas in endemic regions across Africa have susceptible animal and human hosts, dense vector distributions, and source livestock (often from high risk locations to meet the demand for animal protein). Yet, there has never been a documented urban outbreak of RVF. To understand the likely risk of RVFV introduction to urban communities from their perspective and guide future initiatives, we conducted focus group discussions with slaughterhouse workers, slaughterhouse animal product traders, and livestock owners in Kisumu City and Ukunda Town in Kenya. For added perspective and data triangulation, in-depth interviews were conducted one-on-one with meat inspector veterinarians from selected slaughterhouses. A theoretical framework relevant to introduction, transmission, and potential persistence of RVF in urban areas is presented here. Urban livestock were primarily mentioned as business opportunities, but also had personal sentiment. In addition to slaughtering risks, perceived risk factors included consumption of fresh milk. High risk groups’ knowledge and experience with RVFV and other zoonotic diseases impacted their consideration of personal risk, with consensus towards lower risk in the urban setting compared to rural areas as determination of health risk was said to primarily rely on hygiene practices rather than the slaughtering process. Groups relied heavily on veterinarians to confirm animal health and meat safety, yet veterinarians reported difficulty in accessing RVFV diagnostics. We also identified vulnerable public health regulations including corruption in meat certification outside of the slaughterhouse system, and blood collected during slaughter being used for food and medicine, which could provide a means for direct RVFV community transmission. These factors, when compounded by diverse urban vector breeding habitats and dense human and animal populations, could create suitable conditions for RVFV to arrive an urban center via a viremic imported animal, transmit to locally owned animals and humans, and potentially adapt to secondary vectors and persist in the urban setting. This explorative qualitative study proposes risk pathways and provides initial insight towards determining how urban areas could adapt control measures and plan future initiatives to better understand urban RVF potential.

Published: January 2023

The benefits of introducing a systematic lung-protective protocol for coronavirus disease 2019 (COVID-19) pneumonia requiring invasive ventilation in the intensive care unit (ICU) are unknown. Herein, we aimed to evaluate the clinical effects of introducing such a protocol in terms of mortality, duration of ventilation, and length of ICU stay. In this single-centre, retrospective, quality comparison study, we identified patients with COVID-19 pneumonia who received invasive ventilation in our ICU between February 2020 and October 2021. We established a systematic lung-protective protocol for the pre-introduction group until March 2021 and the post-introduction group after April 2021. Patients who did not receive invasive ventilation and who underwent veno-venous extracorporeal membrane oxygenation in a referring hospital were excluded. We collected patient characteristics at the time of ICU admission, including age, sex, body mass index (BMI), comorbidities, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation II (APACHE II) score, and Murray score. The study outcomes were ICU mortality, length of ICU stay, and duration of ventilation. The pre-introduction and post-introduction groups included 18 and 50 patients, respectively. No significant differences were observed in sex, BMI, SOFA score, APACHE II score, and Murray score; however, age was lower in the post-introduction group (70 vs. 56, P = 0.003). The introduction of this protocol did not improve ICU mortality. However, it reduced the ICU length of stay (26 days vs. 11 days, P = 0.003) and tended to shorten the duration of ventilation (15 days vs. 10 days, P = 0.06). The introduction of the protocol was associated with a decrease in the length of ICU stay and duration of ventilation; however, it did not change mortality. The application of the protocol could improve the security of medical resources during the COVID-19 pandemic. Further prospective multicentre studies are needed.
Socio-economic disadvantage and quality Antenatal Care (ANC) in Sierra Leone: Evidence from Demographic and Health Survey

Published: January 2023

Introduction

Reduction of maternal mortality remains a global priority as highlighted by the third Sustainable Development Goal (SDG). This is critical in the case of Sierra Leone as the country is one of three (3) countries with the highest maternal mortality ratio globally, thus 1,120 per 100,000 live births. The approximate lifetime risk of maternal mortality in the country is 1 in 17, relative to 1 in 3,300 in high-income countries. These raise doubt about the quality of the continuum of maternal healthcare in the country, particularly antenatal care and as a result, the objective of the present study is to investigate the association between socio-economic disadvantage and quality antenatal care service utilisation as well as associated correlates in Sierra Leone.

Materials and methods

The study used data from the most recent Demographic and Health Survey (DHS) of Sierra Leone. Only women who had given birth in the five years preceding the survey were included, which is 6,028. Quality antenatal care was defined as receipt of recommended ANC services including uptake of recommended pregnancy drugs (e.g. Fansidar and iron supplement); injections (e.g. tetanus injection) and having some samples (e.g. blood and urine sample) and health status indicators (e.g. blood pressure) taken. An index was created from these indicators with scores ranging from 0 to 6. The scores 0 to 5 were labelled as “incomplete” and 6 was labelled as “complete” and this was used to create a dummy variable. In analysing the data, descriptive analysis was done using chi-square test as well as an inferential analysis using bivariate and multivariate models.

Results

Socio-economic disadvantaged [1.46 (1.09, 1.95), place of residence [2.29 (1.43, 3.67)], frequency of listening to radio [1.58 (1.20, 2.09)], health insurance coverage [3.48 (1.40, 8.64)], getting medical help for self: permission to go [0.53(0.42, 0.69) were seen to have significant relationship with quality of ANC utilized by women during pregnancy. Also, women Mende ethnicity are more likely to utilise quality ANC compared to women from the Temne ethnicity [2.58 (1.79, 3.72)].

Conclusion

Policy makers could consider measures to boost patronage of quality ANC in Sierra Leone by targeting the socio-economically disadvantaged women. Targeting these sub-groups with pro- maternal and child health (MCH) interventions would help Sierra Leone achieve Goal 3 of the SDGs.

Published: January 2023

Background

Rheumatoid arthritis (RA) patients commonly report medicinal cannabis use (MCU). Personality has been independently associated with both RA-related outcomes and MCU, but there is no information available on how they interact in RA patients. This study aimed to investigate a potential association between personality traits and MCU in RA outpatients, as well as to identify additional factors associated with its use.

Methods

This cross-sectional study was performed between June 2020 and August 2021. Consecutive RA outpatients had standardized evaluations using an interview format to collect sociodemographic information, comorbidities, risk of recreational substance use, RA-related disease activity/severity, health-related quality of life, depressive and anxiety symptoms, five personality traits, and MCU in the 12 months before the interview. Multivariable logistic regression estimated adjusted odds ratios (aOR). The study was IRB-approved.

Results

180 patients were included; 160 (88.9%) were women with a mean age of 53.4 ± 13 years. Fifty-three (29.4%) patients reported MCU. Among them, 52 (98.1%) used topical formulations. Neuroticism had the highest overall score (x¯ = 3.47 ± 0.34). Openness to experience trait was higher in MCU patients in the comparative analysis (p = 0.007). In the multivariable regression, higher openness trait (aOR: 2.81, 95%CI: 1.11–7.10) along with moderate risk in tobacco use (aOR: 3.36, 95%CI: 1.04–10.7) and higher RA disease activity/severity (aOR: 1.10, 95%CI: 1.01–1.19) were independently associated with MCU.

Conclusions

In the current study, personality influenced the seeking of MCU for pain relief, associating dynamically with higher disease activity/severity and tobacco use. Contrary to other available information, it did not relate to psychopathology or the recreational use of cannabis. Proactive interdisciplinary clinical evaluations around MCU in RA outpatients should include personality, besides standard clinical assessments, to understand patients’ motivations for its use as they may reveal important clinical information.
Flaunting fat and sharing fashion: A multimodal analysis of how two Black fatshion influencers resist weight stigma on Instagram
Authors: McIntosh Kaitlyn A. , DesRoches Davina M.
Published: January 2023

Fat fashion blogging has largely been celebrated for its resistance potential. Historically, much of this blogging was collaborative with a focus on sharing information and counter-aesthetic images on plus-size fashion. With the rise of the advertising-driven social media platform Instagram, individuals can capitalize on fatshion blogging by becoming social media influencers who promote brands and encourage purchasing decisions. This article uses visual semiotic analysis and critical discourse analysis to show how two fat Black fashion influencers use fashion, flaunting and fat discourse to resist weight stigma. We argue that these efforts complicate our understanding of fat resistance due to the neo-liberal intensification of the entrepreneurial self. Exploring the fat fashion Instagram phenomenon opens new avenues for reflecting on digital resistance to weight stigma and how this is undermined by capitalist interests.
El fotógrafo de Mauthausen/The Photographer of Mauthausen (Targarona 2018): Francesc Boix’s legacy from page to screen
Authors: Brenneis Sara J.
Published: January 2023

El fotógrafo de Mauthausen/The Photographer of Mauthausen () is the first feature film on Spaniards deported to Nazi concentration camps during the Second World War and represents a watershed moment for the country’s collective memory. The film focuses on Francesc Boix, a young Catalan photojournalist who spearheaded a clandestine operation to save photographic evidence of the Nazi’s crimes while a prisoner in Mauthausen. Despite its visual acuity, Targarona’s entry is a complicated addition to the canon of recent concentration camp films, given the director’s positioning of Boix as a macho hero and her counterfactual depictions of Mauthausen. By juxtaposing archival photography with stills from the film, this article traces the recreation of Boix’s experience, as well as how his story has had an enduring impact on the memory of all the Spanish and Catalan survivors of Mauthausen in Spain’s collective imagination.

This work uses the scoping review format to embrace a systematic review of content curation and journalism. This initially entailed an analysis of scientific studies on the process of content curation in the media with a view to establishing their academic impact, identifying their characteristics, and determining their academic evolution. Having established the subjects and the types of studies performed, the resulting document bank was then analysed. Next, semi-structured interviews were held with the researchers who emerged from the scoping review. The results show 2020 to be the year in which the greatest number of academic works were published in this area. Research content notably included studies on content curation and new journalistic formats, curation on social media and online tools, algorithmic curation and content curation and misinformation. Lastly, the data from the 13 interviews helped both to expand knowledge of what content curation in journalism is and to understand its application in current and future journalism work, as well as yielding some benchmark examples of content curation in journalism.

Authors: Martínez-Sanz Raquel , Buitrago Álex , Martín-García Alberto
Published: January 2023

La consolidación de TikTok como una plataforma orientada al mero entretenimiento no ha limitado el empeño divulgativo de profesionales de muy diferentes ámbitos que han encontrado en esta red social una oportunidad para compartir de forma masiva conocimientos rigurosos, útiles y desmitificadores (Guiñez-Cabrera y Mansilla-Obando, 2022; Yalamanchili et al., 2022). A través de una metodología basada en el análisis de contenido, se examinan las publicaciones y las reacciones de los principales perfiles de temática farmacéutica en TikTok, profundizando en los recursos comunicativos, estrategias de interacción y temas con los que conectan con su audiencia. Los resultados revelan que, a diferencia de otros espacios digitales más propensos a la crispación y el enfrentamiento, los influencers farmacéuticos pueden exponer abiertamente su experiencia y opinión profesional, demostrando, además, un dominio de los recursos técnicos que ofrece TikTok para crear vídeos divulgativos sobre salud. El empleo de un lenguaje cercano y alejado de tecnicismos, sumado a un tono natural y con ciertas dosis de humor, representan sus señas de identidad y la clave de la buena acogida por parte de una audiencia que responde (79.696 comentarios analizados) de forma asertiva planteando dudas, relatando sus propias experiencias y, sobre todo, expresando apoyo a las tesis defendidas por el profesional. Ante un tema de interés general como es la salud, todo esfuerzo por emplear las herramientas y códigos de comunicación propios de la población joven contribuye a integrarlos en los nuevos circuitos de divulgación.
Effect of village funds and other variables on economic growth of Central Java Province 2015–2018
Authors: Rizka Amalia Farentina
Published: January 2023

The Economic growth of Central Java Province from 2015 to 2018 experienced a slowdown compared to other provinces in Java. One of the main focuses on improving the economy is fiscal decentralization which is manifested in the form of village funds. This is in line with one of nine development priorities for the next five years agendas, or so- called Nawacita, namely to develop Indonesia from the periphery by strengthening regions and villages within the framework of a unitary state. The village funds data from the Ministry of Finance shows that Central Java Province receives the largest village funds each year, but this does not necessarily increase economic growth in the recipient districts. In addition to the economic growth policy, the government also plans through investment and government spending. The purposes of this study are to determine the effectiveness of the village fund budget and the effect of the realization of village funds, capital expenditure, goods and services expenditure, and the level of open unemployment on economic growth. The method used in this study is the panel data regression analysis method with the research locus of 29 districts receiving village funds in Central Java Province from 2015 to 2018. The results of the study using the selected panel data regression model that is the Fixed Effect Model FGLS SUR show that all independent variables influence significantly to economic growth (GRDP). The variable realization of village funds and goods and services expenditure has a significant positive effect, while the variable realization of capital expenditure and the variable open unemployment has a significant negative effect on economic growth (GRDP).
- Does electricity consumption influence economic growth in Indonesia?
Authors: Sari Vita Kartika Sari
Published: January 2023

The purpose of this study was to analyze the influence of electricity consumption, investment, and school enrollment on economic growth of Indonesia from 1984-2018. Electricity is used by society in every activity including production and consumption. This study used ARDL-ECM method. Based on the estimation results, all variables were stationary at the first difference. Based on the empirical findings, the appropriate ARDL model was ARDL (1, 2, 1, 1). In the long run, investment had a positive influence on economic growth and school enrollment had a negative influence on economic growth. Meanwhile, in the long run, electricity consumption is insignificant to the economic performance of Indonesia during the study period. However, in the short run, there was only investment had a significant and positive impact on economic growth in Indonesia. School enrollment and electricity consumption had no significant influence on economic growth. Speed of adjustment (ECT (-1)) had a significant influence on GDP. With the Qusum and QusumQ tests, the model showed feasible stability. Therefore, more vigorous electricity policies should be implemented for supporting economic growth.

Published: January 2023

The article describes the methodology of teaching the rules for the image of aviation products made of sheet material obtained by cutting, bending, drawing, etc. These rules, according to the graduate's competence model, are necessary for students to study design specialties of aviation universities. The proposed methodology implies the study of these rules in the framework of performing specialized graphic work in the discipline “Engineering Graphics”. The methodology includes a description of the structural elements of sheet parts and the features of their image in the drawings. Special attention when teaching this topic should be paid to the requirements for maintaining the strength and rigidity of the structure with a minimum weight. These requirements make it necessary to introduce special elements into the design of parts, such as bending, flanging, rifts, etc., as well as the need to depict scans in the drawing in order to clarify the shape of the parts. The considered examples allow students to form practical skills and abilities for displaying products made of sheet material in drawings; to acquire skills for reading drawings of thin-walled aircraft structures; to deepen knowledge of the state ESKD standards for the development and design of drawings of metal structures; to develop technical thinking. The material was tested while teaching the discipline “Engineering Graphics” at the Moscow Aviation Institute (National Research University).

INVESTIGATION OF OSCILLATING ROLLER OPERATING MODES
Authors: Shishkin E. A. , Kravtsov Z. S.
Published: January 2023

The rigidity of the compacted material, the amplitude and frequency of the vibration exciter, the operating speed affect the operating mode of the oscillating roller. The following operating modes are distinguished: clutch, one-way slip, asymmetric slip, symmetrical slip. The latter mode is undesirable and should be avoided in the practice of using oscillatory rollers. The objective of the study is to establish the indicator of the transition of the oscillatory roller to the symmetrical sliding mode. In this paper, simulation modeling of the oscillatory motion of an oscillatory roller using the fast Fourier transform functional is carried out. As a result of modeling, it was found that as the operating mode of the roller approaches the symmetrical sliding mode, the amplitudes of even frequency components 2f, 4f, etc. tend to zero in the spectrum of the curve of the horizontal acceleration of the roller. As a condition for the inefficiency of the oscillating roller, it is accepted that the ratio of the amplitudes of the frequency components A2f /Af reaches a certain value of Asim, which depends on the physical and mechanical characteristics of the compacted material, and is determined experimentally. The results of the study can be used in the design of an intelligent control system for an oscillating roller.

COMPARATIVE ANALYSIS OF TECHNICAL AND ECONOMIC INDICATORS OF THE OPERATIONAL EFFICIENCY OF MACHINES FOR ANTI-ICE TREATMENT OF PAVEMENTS
Authors: Mandrovskiy K. P. , Sadovnikova Ya. S.
Published: January 2023

The article touches upon one of the most important problems associated with the winter maintenance of road construction elements (sidewalks, footpaths), namely, winter street injuries of pedestrians. As one of the possible solutions to this problem, a disk distributor with a symmetrical method of supplying solid anti-icing material to the disk is proposed for operation, which provides a better distribution compared to the traditional asymmetric method of supply. It is assumed that this equipment will be installed on the base machine – a typical distributor of anti-icing materials along the carriageway. The article carried out a comparative technical and economic analysis and evaluation of the technical and economic indicators of the operation of machines in order to select the most effective combination of machines for de-icing the roadway and sidewalks. Six models of machines were selected for analysis, similar in their technical characteristics to real machines used for the distribution of solid anti-icing materials. As a criterion for the efficiency of operation, the cost of production of work, the annual volume of work and operational shift productivity were chosen. As a result of the analysis, it was found that the operation of combinations of machines, including a disk distributor with a symmetrical feed method, will allow achieving higher technical and economic indicators due to a slight increase in the cost of production of anti-icing coatings.

Published: January 2023

The paper considers the basic concepts of a mathematical model. The connection between the model and reality and its place and relevance in the modern world is shown. The developed mathematical model of a servo pneumatic device, which includes an actuator and a proportional or discrete pneumatic valve, is presented. The basic equations describing the dynamics of the servo pneumatic device, boundary and initial conditions are given, which make it possible to analyze the stability of the drive. A non-linear object-oriented computer model of a pneumatic servo device is presented. The model is built in the form of block diagrams of equations that describe the relationship between the original physical quantities. The influence of the nature of the inductance of the electromagnet coil on the dynamic properties of the system is shown. The developed method for identifying the transfer function of pneumatic devices and its application in the preparation of mathematical models is presented. A technique for studying the stability of pneumatic systems has been created, based on establishing an unambiguous relationship between the experimentally obtained frequency characteristics of the pneumatic apparatus included in the system and the type of its transfer function. The form of transfer functions for the pneumatic devices under consideration is obtained. For the proportional pneumatic valves presented in the work, the quality indicators of transient processes in the time domain are formulated and determined, and the phase and amplitude margins are found. The criteria for the performance of pneumatic systems are formulated. The ratios for determining the described criteria are given. The boundaries of the operability of systems with a pneumatic drive have been established. The scientific novelty of the results presented in the work is that a non-linear object-oriented computer model of a servo pneumatic device has been created, unlike the existing ones, it is built in the form of block diagrams of equations that describe the elationship between the initial physical quantities, and has the principle of modularity.
