Authors:   Bila Tserkva National Agrarian University, Kuzmenko Anastasiia
Published: November 2021

The article deals with the features of higher education of the third level in Latin America, namely Brazil and Mexico. The object of the research is the quality system of higher education in Latin America (Brazil and Mexico), and its subject is the formation and attitude to the culture of academic integrity of PhD-applicants in these countries. The goal is highlighting the implementation of the leading practices for the formation of the academic integrity culture among PhD-applicants in Latin America, in particular Brazil and Mexico. Objectives are to consider ways of forming the academic integrity culture of PhD-applicants at the international, state and institutional levels in Latin America, in particular Brazil and Mexico. It has been investigated that scientific activity is widely developed in Brazil, and the basis for the formation of academic integrity is used according to the experience of the United States of America. However, violations such as plagiarism or deception are perceived not as a manifestation of unethical behaviour, but more as a violation of ignorance or unintentional borrowing. There is also a low level of success of applicants for higher education, which is also fruitful for the generation of dishonest behaviour. Mexico is the «opposite lever» in the experience of the academic integrity culture, since the economic system of the country has its own gaps and leads to a high level of corruption, and as a result, the manifestation of academic dishonesty in all its forms. Despite this, the country understands the need to form the academic integrity culture as a factor influencing the further responsible and ethical activities of a future competitive specialist. Thus, there is a cyclical nature: the honest behaviour of the applicant for education forms the skills of the honest behaviour of a specialist, the honest behaviour of a specialist is the absence of corruption, in particular in education.

Authors:   State Institution Luhansk Taras Shevchenko National University, Morozova Marharyta
Published: November 2021

The article considers the genesis of the concept of «interactivity» in modern psychological, pedagogical and methodological research. It is determined that interactivity runs through the entire history of pedagogical education. The paper analyzes the concept of «interactivity» in pedagogy, methods of teaching foreign languages, programming, telecommunications, multimedia, design, cultural studies, literature, sociology. The purpose of the educational process is to prepare future teachers for professional activities in rapidly changing conditions, the formation of thinking as a factor in the formation of the modern personality of the future teacher and the introduction of democratic values in future teachers of the new generation. It is noted that the competence approach in the organization of the educational process requires the teacher to change the learning process: its structure, forms of organization of activities, the principles of interaction of subjects. It is established that in interactive learning the interaction of the teacher and the future teacher changes: the activity of the teacher gives way to the activity of future teachers, and the task of the teacher is to create conditions for their initiative. The learning process is organized in such a way that almost all its participants are involved in the process of cognition, they have an opportunity to understand and reflect on what they know and think. It is found that the peculiarity of interactive methods is the high level of mutually directed activity of the subjects of interaction, emotional, spiritual unity of the participants.

Authors:   Kherson State Agrarian and Economic University, Yatsula Tetiana
Published: November 2021

The article considers the essence of subject – subject relationship. The author proved that creative cooperation, interaction, in which is based on the subject-subject relationship, aimed at a deeper reflection of one's own world and its enrichment with the world of another person. The analysis presented by the author allows us to understand the value of subject-subject relationships for the teacher as his ability to be a significant person in the development of the future specialist. In this context, creative cooperation, the teacher's relationship with students is a value-meaning-oriented activity that allows to find not only the meaning of interaction, but also the meaning of one's own life. Not only from the standpoint of subject-subject interaction, but also from the standpoint of «internal dialogic consciousness» of the teacher during the interaction Dialogic consciousness involves empathic perception of features, «deep» penetration into the human world. At the heart of the subject-subject relationship between teacher and student is dialogue. The participants of the dialogue are in a state of understanding. Dialogue involves: interest in human subjectivity, the desire to know the peculiarities of worldview, values, and attitudes and provides an opportunity based on the involvement of the worlds of teacher and student to internalize their values, views, positions in the student's worldview. Its participants. In the process of such a dialogue there is a self-realization of the creative «I-concept» of both the teacher and the student. The ability to present oneself is important for a teacher. And this is not only knowledge of the subject taught, pedagogical skills, but also openness to present the world of their hobbies.

This study determined the nutritional values of ground perilla cake (GPC) and the potential for dietary supplementation in growing pigs based on in vitro ileal digestibility (IVID) and apparent total tract digestibility (ATTD). The IVID evaluated at four dietary supplementation levels: 0, 5, 10, and 20%. The ATTD was measured by using twenty-four grower crossbred pigs. Pigs were randomly assigned to three dietary supplementation levels (0, 5, and 10%). From these analytical results, GPC raw material contained crude protein (CP) content (31.54%). That total essential amino acid (EAA) was 138.34 mg/g, mainly leucine (28.87 mg/g), and contained notably limiting amino acids for pigs, such as lysine (19.52 mg/g) and methionine (10.94 mg/g). The ether extract content (EE) was 10.52%, and the major free fatty acid (FFA) was linolenic acid (C18:3n3; 55.97%) and the fat-soluble vitamins included γ-tocopherol (367.25 μg/100g). In addition, GPC contained minerals such as phosphorus (1.02%), potassium (0.83%), calcium (0.46%), and iron. However, crude fiber (CF) had a notably high content (24.43%). Increasing GPC levels in pig diets reduced the IVID of dry matter (DM), EE, and CF (P<0.05), especially the 20% GPC supplement. The IVID of the CP did not differ among the groups. Furthermore, the results for the ATTD of the CP and EE in the 5% GPC supplement group were significantly better than that of the other groups (P˂0.05). We found the potential of GPC as an alternative protein source. Moreover, it contained high energy and polyunsaturated fatty acid.

Published: November 2021

A preparation of essential oils to control chicken lice (Menopon gallinae) and mites (Ornithonyssus bursa) was developed. Each essential oil was effective against lice and mite in vitro. Citronella oil at the lowest concentration of 0.208 µg/cm2 resulted in a mortality rate of 100% in chicken lice, whereas a higher concentration of cloves, lemongrass, ginger, Makwan oil (0.416 µg/cm2), and Litsea oil (0.832 µg/cm2) was also found to be effective. A 100% rate of mortality for mites was observed using citronella and ginger oil at a concentration of 0.416 µg/cm2. At the same concentration, cloves, lemongrass, Litsea, and Makwan oil exhibited mortality rates in mites of 77.96%, 93.33%, 87.30%, and 93.49%, respectively. The efficacy of citronella oil and ginger oil against lice and mites was further examined in vivo. Citronella and ginger oil affected the rate of decline in lice from day 1 to day 14, whereas the number of mites living in nests declined from day 1 to day 7. The reduction of these parasitic insects may be correlated with the chemical constituents present in each essential oil. The active ingredients likely acted insecticidal agents against both parasitic insects. Moreover, the preparation developed here did not cause any side effects, such as dermatitis and respiratory disorders, during animal trials. Hence, preparations comprised of the essential oils of citronella and ginger can be further developed and used as insecticidal agents to control and/or eliminate chicken lice and mites on commercial farms.
Study of Fingering Dynamics of Two Immiscible Fluids in a Homogeneous Porous Medium with Considering Wettability Effects Using a Pore-Scale Multicomponent Lattice Boltzmann Model
Authors: Ezzatneshan Eslam , Goharimehr Reza
Published: November 2021

In the present study, a pore-scale multicomponent lattice Boltzmann method (LBM) is employed for the investigation of the immiscible-phase fluid displacement in a homogeneous porous medium. The viscous fingering and the stable displacement regimes of the invading fluid in the medium are quantified which is beneficial for predicting flow patterns in pore-scale structures, where an experimental study is extremely difficult. Herein, the Shan-Chen (S-C) model is incorporated with an appropriate collision model for computing the interparticle interaction between the immiscible fluids and the interfacial dynamics. Firstly, the computational technique is validated by a comparison of the present results obtained for different benchmark flow problems with those reported in the literature. Then, the penetration of an invading fluid into the porous medium is studied at different flow conditions. The effect of the capillary number (Ca), dynamic viscosity ratio (M), and the surface wettability defined by the contact angle (θ) are investigated on the flow regimes and characteristics. The obtained results show that for M<1, the viscous fingering regime appears by driving the invading fluid through the pore structures due to the viscous force and capillary force. However, by increasing the dynamic viscosity ratio and the capillary number, the invading fluid penetrates even in smaller pores and the stable displacement regime occurs. By the increment of the capillary number, the pressure difference between the two sides of the porous medium increases, so that the pressure drop Δp along with the domain at θ=40∘ is more than that of computed for θ=80∘. The present study shows that the value of wetting fluid saturation Sw at θ=40∘ is larger than its value computed with θ=80∘ that is due to the more tendency of the hydrophilic medium to absorb the wetting fluid at θ=40∘. Also, it is found that the magnitude of Sw computed for both the contact angles is decreased by the increment of the viscosity ratio from Log(M)=−1 to 1. The present study demonstrates that the S-C LBM is an efficient and accurate computational method to quantitatively estimate the flow characteristics and interfacial dynamics through the porous medium.
Heat Transfer Model of Pneumatic End-Position Cylinder Cushioning
Authors: Nazarov Fedor , Weber Jürgen
Published: November 2021

In this paper a thermal model of a pneumatic cylinder with an integrated pneumatic end cushioning is presented. Being a part of a multidomain model presented in former research, this model is needed to simulate and analyse the thermodynamic processes in the pneumatic end cushioning and to elaborate a novel design strategy for damping systems with a higher capability on kinetic energy absorption and robust performance under fluctuating operating conditions. For this purpose, a proper heat exchange model is inevitable to calculate the pressure in the cushioning volume and consequently the deceleration of the load. An approach of splitting the complex geometry of cylinder into simple geometries, such as plain or cylindrical surfaces, is used in this study for a fast computation of convective heat flow rates. To validate this approach, the simulation results were compared with the measurements, carried out at different supply pressures, piston speeds and end cushioning throttle openings. The model will be used further for sensitivity analysis and robust optimisation of the cushioning system design.
Optimisation of a Pump-Controlled Hydraulic System using Digital Displacement Pumps
Authors: Larsson L. Viktor , Lejonberg Robert , Ericson Liselott
Published: November 2021

When electrifying working machines, energy-efficient operation is key to maximise the use of the limited capacity of on-board batteries. Previous research indicate high energy savings by means of component and system design. In contrast, this paper focuses on how to maximise energy efficiency by means of both design and control optimisation. Simulation-based optimisation and dynamic programming are used to find the optimal electric motor speed trajectory and component sizes for a scooptram machine equipped with pump control, enabled by digital displacement pumps with dynamic flow sharing. The results show that a hardware configuration and control strategy that enable low pump speed minimise drag losses from parasitic components, partly facilitated by the relatively high and operation point-independent efficiencies of the pumps and electric motor. 5–10% cycle energy reductions are indicated, where the higher figure was obtained for simultaneous design and control optimisation. For other, more hydraulic-intense applications, such as excavators, greater reductions could be expected.

Authors: Liu Jianbin , Sitte André , Weber Jürgen
Published: November 2021

Good estimation of flow mapping (FM) and inverse flow mapping (IFM) for electrohydraulic valves are important in automation of fluid power system. The purpose of this paper is to propose adaptive identification methods based on LSM, BPNN, RBFNN, GRNN, LSSVM and RLSM to estimate the uncertain structure and parameters in flow mapping and inverse flow mapping for electrohydraulic valves. In order to reduce the complexity and improve the identification performance, model structures derived from new algorithm are introduced. The above identification methods are applied to map the flow characteristic of an electrohydraulic valve. With the help of novel simulation architecture via OPC UA, the accuracy and efficiency of these algorithms could be verified. Some issues like invertibility of flow mapping are discussed. At last, places and suggestions to apply these methods are made.

Published: November 2021

In this day and age, information security is becoming a priority not only in the system of international economic relations but also at the state level. This study aims to study the effect of a ‘digital’ country’s information security on its political stability through quantitative analysis. The study is a mixed research design with a focus on the Russian Federation and the Republic of Kazakhstan. Its methodological basis is represented by the collection and analysis of data on the level and nature of cybersecurity threats (Global Cybersecurity Index, the number of cyber incidents) and on the level of political stability (Political Stability and Absence of Violence/Terrorism indicator of the Worldwide Governance Index). The results of the study show that Russia with a GCI 2020 score of 98.06 and Kazakhstan with a GCI score of 93.15 have relatively low levels of political stability. This is evidenced by their 45.7 and 25.7 percentile ranks on Political Stability and Absence of Violence/Terrorism and a high frequency of offenses using information and communication technologies. Findings suggest that with a high level of commitment to information security, the growth in cyber incidents will not necessarily affect political stability. The obtained findings provide countries an insight into cybersecurity within the national system as well as present a great deal of data on best practices to work through gaps in the national culture of cybersecurity at the state level. The results and methodology of this study can be used by officials to develop information security strategies and tactics, as well as by other researchers for quantitative analysis of the relationship between information security and political stability of different countries and regions.

Authors: Vishva E. Sri , Aju D.
Published: November 2021

Fundamentally, phishing is a common cybercrime that is indulged by the intruders or hackers on naive and credible individuals and make them to reveal their unique and sensitive information through fictitious websites. The primary intension of this kind of cybercrime is to gain access to the ad hominem or classified information from the recipients. The obtained data comprises of information that can very well utilized to recognize an individual. The purloined personal or sensitive information is commonly marketed in the online dark market and subsequently these information will be bought by the personal identity brigands. Depending upon the sensitivity and the importance of the stolen information, the price of a single piece of purloined information would vary from few dollars to thousands of dollars. Machine learning (ML) as well as Deep Learning (DL) are powerful methods to analyse and endeavour against these phishing attacks. A machine learning based phishing detection system is proposed to protect the website and users from such attacks. In order to optimize the results in a better way, the TF-IDF (Term Frequency-Inverse Document Frequency) value of webpages is employed within the system. ML methods such as LR (Logistic Regression), RF (Random Forest), SVM (Support Vector Machine), NB (Naive Bayes) and SGD (Stochastic Gradient Descent) are applied for training and testing the obtained dataset. Henceforth, a robust phishing website detection system is developed with 90.68% accuracy.

Sybil accounts are swelling in popular social networking sites such as Twitter, Facebook etc. owing to cheap subscription and easy access to large masses. A malicious person creates multiple fake identities to outreach and outgrow his network. People blindly trust their online connections and fall into trap set up by these fake perpetrators. Sybil nodes exploit OSN’s ready-made connectivity to spread fake news, spamming, influencing polls, recommendations and advertisements, masquerading to get critical information, launching phishing attacks etc. Such accounts are surging in wide scale and so it has become very vital to effectively detect such nodes. In this research a new classifier (combination of Sybil Guard, Twitter engagement rate and Profile statistics analyser) is developed to combat such Sybil nodes. The proposed classifier overcomes the limitations of structure based, machine learning based and behaviour-based classifiers and is proven to be more accurate and robust than the base Sybil guard algorithm.

Abstract. Hidayat R.A, Partasasmita R, Iskandar J, Gunawan B. 2020. Changes in paddy field management in Sindang Hamlet, Rancakalong Village, Sumedang District, West Java, Indonesia. Biodiversitas 21: 98-105. Farmers have traditional ecological knowledge related to the management of their fields, including knowledge of climate, soil types, soil fertility, various plants and animals, plant pests and irrigation. This knowledge is based on customs, beliefs and cosmos. Over time, government policies in agriculture such as the green revolution were implemented with the aim of increasing productivity of rice in wet-rice field farming. This initiated a change in the community's farming system from subsistence farming to commercial farming. Not to mention the existence of climate change that requires people to adapt. This change has an impact on ecological, economic and social aspects which are interesting to study. This study conducted in Sindang Hamlet, Rancakalong Village,  Sumedang District, West Java, which is known to have local rice cultivars and still practices rituals related to rice management. This study aims to analyze the changes in paddy management system in Sindang Hamlet due to green revolution and climate change, using qualitative data collection methods such as semi-structured interviews (deep interviews) with competent locals and participatory observations. Result of study showed that presently there are 3 groups of farmers in Sindang Hamlet, farmers who plant only local rice cultivars, farmers who plant only superior rice cultivars, and farmers who plant both local rice and superior rice cultivars in their land. Most farmers in Sindang Hamlet planted local rice but the diversity of local rice has decreased leaving only six cultivars, namely rayot, mesir, omas, torondol, mataram and randa kaya. There are still farmers in Sindang Hamlet who practice traditional farming, but many are starting to use modern tools and synthetic chemicals. The rice field management ritual called ngalaksa is still observed by the community, although there are some changes over time. The changes in rice field management have a negative impact on the local environment, economy and social aspects.

Introduction: Giant cell tumor (GCT) most commonly involves distal femoral condyles, distal end of radius, proximal tibial plateau, and proximal humerus. GCT is uncommon to occur in small bones of hand and feet. 2% of GCT occur in hand. The incidence of GCT in foot is 1.2–1.8%. Only a few cases have been reported in literature worldwide. GCT is the most common cause of secondary ABC. We report a case of GCT of intermediate cuneiform in a 25-year-old female evolving into aneurysmal bone cyst (ABC).

Case Report: A 25-year-old female presented to us with complaints of pain and swelling over the dorsum of right foot for a period of 1 year. On examination, there was a localized ovoid-shaped swelling of 2 by 2 cm over the dorsum of right foot. Radiographs revealed a well-defined osteolytic lesion in the intermediate cuneiform. T2 MRI showed hyper-intense lesion in intermediate cuneiform. The patient was taken up for surgery, and the intermediate cuneiform was excised completely. Removed bone was sent for histopathological examination which confirmed it to be GCT evolving into secondary ABC. The patient was followed for 1 year and had no complaints. The patient was able to weight bear and walk without any difficulty. There was no recurrence of lesion.

Conclusion: GCT of the cuneiform evolving into ABC is a very rare presentation. The treatment of choice is excision of the tumor with or without bone grafting. Any osteolytic lesion in the small bones must be evaluated and should be intervened in the early stage.

Tissue Engineered Successful Reconstruction of a Complex Traumatized Lower Extremity
Authors: Saha Srinjoy
Published: November 2021

Introduction: Tissue engineered reconstruction is a minimally invasive approach for healing major complex wounds successfully. It combines accurate, conservative debridement with a specially adapted suction method, platelet-rich plasma (PRP) injections, and biomaterial application to salvage injured tissues and grows new soft tissues over wounds.

Case Report: A healthy young man in his early 30s presented to our emergency department with complex knee-thigh injuries following a high-velocity automobile accident. Degloved anterolateral thigh, severe thigh muscle injuries, and ruptured extensor patellar mechanism were observed. Accurate conservative (as opposed to radical) debridement and PRP injections salvaged the injured muscles and tendons. Specially carved reticulated foam wrapped around the injured ischemic muscles, followed by low negative, short intermittent, cyclical suction therapy. Wound exploration 4 days apart revealed progressive improvements with considerable vascularization of the injured soft tissues within 2 weeks. Thereafter, meticulous reconstruction of the salvaged muscles and tendons restored anatomical congruity. An absorbable synthetic biomaterial covered the sizeable open wound with vast areas of exposed tendons. Five weeks later, exuberant granulating tissue ingrowth within the biomaterial filled up the tissue defect. A split-skin graft covered the remaining raw areas, which “took” completely. Early rehabilitation enabled the patient to return to active work, play contact sports, and perform strenuous activities effortlessly.

Conclusion: Minimally invasive tissue engineered reconstruction is a novel approach using a series of simple minimally invasive procedures. It lessens the duration of surgery and anesthesia, maximizes soft-tissue salvage, lowers morbidity, minimizes hospitalization, saves costs, and improves the patient’s quality of life significantly.
