Published: February 2023

In spite of positive impact in it, authoritarian nursery is essential to be studied because of its negative effect to children This article aims to determine the cause of authoritarian parenting in early childhood in Sleman district. This research was qualitative research with a case study approach. It is a single case study with one research subject. This research is not intended to generalize, but shows the importance of phenomena encountered in other families as well. One case in Sleman district that has implemented authoritarian parenting to her children was showed by tight rules, not involvement of the children to agree with the parents and verbal abuse in harsh words and yelling’s as the punishment. The research result showed that the leading cause of Mrs R committed authoritarian parenting toward her children is caused by several reasons parenting style from the elders who are authoritarian when instilling religious education, the circumstance outside the home that caused parents to be more protective toward their children, the demands of religion-based schools make the parents more rigid to educate their children, and the influence of parents’ diversity background adhered to the particular tenet.

Authors: Munjin Munjin
Published: February 2023

In now days, character is to be something very important in a technological era. If the materialistic advantages and benefits obtained from the advancement of the industrial era are not followed by the adequacy of immaterial factors, it will certainly bring about chaos in personal and social lives. Furthermore, the impact of the two sides disharmony will at least trigger three things. First, moral decline in community,  second, the decreasing sense of togetherness and unity, third, interpersonal interaction has changed. So, human being needs identity and character in order to not experience disorientation in life. This paper aims to  describe the characteristics of the disciples of Tarekat Naqsabandiyah-Kholidiyah in central Java, Indonesia and to analyze how the values of character education formed within the disciples of Tarekat Naqsabandiyah Khalidiyah. The methods used in collecting data were in depth interview, observation, and documentation. Having collected, they would be analyzed by steps like collecting, reduction, displaying data and drawing conclusion. The result showed internalization of the values were performed by integrated ways which combined either internal or external factors. Internal  factors was started by pure motivation  in each disciples’ inner heart. The external factor consisted of family, tarekat teaching, mursyid model, and jama’ah. The educational character along with the jama’ah tarekat can be categorized into  three major characters namely; wisdom, keep avoiding the bad deed, and courage. These characters are also contained in educational character, and the most important thing is how the formal education can imitate the method used  in building that character

Height and weight measurements are an important element of every child’s visit to the paediatrician’s or family doctor’s office. Short stature is defined as a height below the 3rd percentile for age and sex. It is important to identify children in the short stature group (3% of the population) whose short height is not due to familial factors and therefore requires treatment. Correct measurement of the child’s height followed by its plotting onto a sex- and age-appropriate percentile chart is the first step to identify the problem of short stature in a child. This should be followed by determining the target height and growth rate. Therefore, regular updating of child’s medical record book is of key importance. Diagnostic work-up is needed in children with height below the 3rd percentile or with height difference of more than 2 percentile channels compared to the mean parental height, as well as in children with excessively slow growth rate (indicated by progressive decrease of percentile height position).

A 17.5-year-old boy, previously treated in a nephrology clinic due to chronic proteinuria, was referred for a routine cardiology consultation before being transferred to an adult clinic for further care. Physical examination and echocardiography showed no circulatory abnormalities and normal blood pressure, while echocardiography revealed an abnormal tumour-like structure measuring 1.3 × 1.5 cm in the left atrium, remaining in contact with the interatrial septum. Continuous infusion of heparin was started, after which no change in tumour size was obtained. The diagnosis was extended to include computed tomography, which showed a soft 1.5 × 2.1 × 2.1 cm tissue structure connecting with the interatrial septum with uneven contours, and magnetic resonance imaging, which indicated that the left atrial structure corresponded to myxoma, and the presence of enhancement spoke against the suspicion of a thrombus, although the presence of a small thrombus on the tumour could not be clearly excluded. The boy was qualified for a cardiac surgery, during which the pathological structure was removed and then sent for histopathological analysis, which revealed a heart tumour with myxoma. After the surgery, the patient was transferred to the department of paediatric cardiology for further treatment, where he received enoxaparin sodium, antibiotics and acetylsalicylic acid. After a few days, an about 1 cm layer of fluid appeared in the pericardium, which regressed after the incorporation of ibuprofen and dehydrating agents. After 2 weeks, the boy was discharged home in good condition, with a recommendation to continue care at a nephrology, cardiology and genetic clinic due to MTHFR mutation, which may be associated with hereditary hypercoagulability, detected during hospital stay.

Schneiderian papilloma is a benign sinonasal tumour, which has three morphological variants: fungiform, inverted and oncocytic. Inverted papilloma, being the most prevalent variant, is three times more common among males in their fifth to seventh decade of life. On the other hand, nasopharyngeal carcinoma is a malignant tumour arising from the nasopharyngeal epithelium. Albeit rare, synchronous sinonasal tumour has been reported and remains a quandary till date, especially when it involves malignant and benign synchronous nasal mass. In this paper, we reported a case of a successfully treated synchronous sinonasal inverted papilloma with nasopharyngeal carcinoma in an elderly male. We would like to highlight the need to investigate suspicious bilateral nasal masses due to the possible coexistence of two different pathologies, as in our case.

Duchenne muscular dystrophy is the most common inherited neuromuscular disorder. The onset of myopathic symptoms is observed at an average age of 2.5 years. However, the definitive diagnosis is not reached until between 3 and 5 years of age, indicating a delay in relation to the onset of first symptoms. The diagnosis is confirmed with genetic testing. This paper presents a case of a 6.5-month-old boy with reduced motor activity already in the foetal period, hypertransaminasaemia, constipation and reduced muscle tone. Extensive differential diagnosis of these abnormalities, including genetic testing, confirmed Duchenne muscular dystrophy. Detection of this disease at an early, poorly symptomatic stage offers a chance to achieve better treatment outcomes and improve the patient’s quality of life. Modern gene therapies implemented before irreversible changes are induced by the disease may in the future give the patient a chance to be completely cured. In the presented case, the symptoms of myopathy were present already in foetal life, and the diagnosis was reached at a younger age than the typical age reported in most of the available literature data.

Normal sodium levels in the extracellular fluid are in the range of 135–145 mmol/L. Low serum sodium (hyponatraemia) is a common water and electrolyte balance disorder. Dehydration and overhydration are the most common causes of hyponatraemia in children. This paper describes a case of a 2.5-year-old boy admitted to the paediatric ward due to pneumonia. The child showed reluctance to fluid intake, hypoosmolar hyponatraemia with hypouricaemia, and increased urinary sodium excretion in the absence of abnormalities in hydration status. He had a family history of persistent hyponatraemia and hypertension in his grandfather. After excluding pituitary, thyroid, adrenal cortex pathologies, kidney disfunction, and proliferative processes in the differential diagnosis, cerebral salt wasting syndrome, the syndrome of inappropriate secretion of antidiuretic hormone and the renal-related syndrome of inappropriate antidiuresis were taken into account. The aim of the study was to discuss the differential diagnosis of chronic euvolemic hyponatraemia and to draw attention to the need for genetic testing for the nephrogenic syndrome of inappropriate antidiuretic hormone secretion caused by activating point mutations of the vasopressin 2 receptor gene (V2R).

Purpose - to determine the results of the use of bacteria of the genus Bacillus spp. in the form of a spray (Bioplasmix spray for throat) in the treatment of the children with acute tonsillopharyngitis. Materials and methods. An open, randomized, controlled, post-registration study was conducted among 60 children aged 3-17 years diagnosed with acute respiratory viral infection (ARVI), acute tonsillopharyngitis, who were treated in the clinic of pediatric infections of the Bogomolets National Medical University, Kyiv. Children were divided into two groups - main and control. The control group consisted of 30 children who received treatment in accordance with the local protocol for the diagnosis and treatment of acute respiratory viral infections and influenza, and the main group consisted of 30 children who received in addition to the protocol treatment the prophylactic and hygienic agent Bioplasmix throat spray 2-3 injections 3-4 times a day. Bacterial etiology of tonsillopharyngitis was excluded using the McIsaac diagnostic scale. The study involved children with acute viral tonsillopharyngitis, who had 0-2 points on this scale. The results of the pilot observation indicate a positive effect of the drug Bioplasmix Throat Spray on the course of acute viral tonsillopharyngitis in children. This effect was manifested by a reduction in the time of normalization of the main clinical symptoms, such as fever, sore throat and inflammation of the oropharyngeal mucosa. It should be noted that during the observation period, no adverse reactions were registered in patients who used Bioplasmix Throat Spray, which confirms the high safety profile of the drug and indicates its good tolerability. Conclusions. The use of probiotic bacteria Bacillus spp. (Bioplasmix throat spray) helps to reduce the viral load and eliminate the pathogen, destroy bacterial biofilms, antagonistically displace bacteria, in particular staphylococcus, facilitates the course of ARVI and accelerates the recovery of patients without the development of bacterial complications. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.
Analysis of the effects of a two-year course of allergen-specific immunotherapy in children with atopic dermatitis and sensitization to house dust mites
Authors:   Bogomolets National Medical University, Kyiv, Ukraine, Mozyrska O.V.
Published: February 2023

Atopic dermatitis is a chronic inflammatory skin disease that affects 15% to 30% of children and 2% to 10% of adults worldwide. Some observations suggest that allergens may be an important cause of atopic dermatitis. Allergen-specific immunotherapy can reduce symptoms in people with atopic dermatitis by suppressing abnormal immune responses to allergens. Purpose - to evaluate the role of sublingual immunotherapy in the treatment of atopic dermatitis in children with sensitization to house dust mite, by conducting a randomized 24-month clinical trial with house dust mite extract. Materials and methods. The study included 26 children with atopic dermatitis, sensitized to house dust mites. 12 patients received sublingual immunotherapy and 14 patients received only symptomatic treatment (the control group). The disease activity of atopic dermatitis was evaluated using the dynamics of SCORAD indicators and the CDLQI questionnaire. Results. After 24 months from the start of treatment, the decrease in SCORAD was 52.1% in the sublingual immunotherapy group (Wilcoxon T-test, T-W=78.0; p<0.001) and 20.2% in the control group. The decrease in CDLQI after 24 months was 40% in the sublingual immunotherapy group (T-W=66.0; p<0.001), in the control group no improvement was found. We have not found influence of age and degree of severity on the effectiveness of therapy. Conclusions. This randomized 2-year study showed that sublingual immunotherapy with house dust mite extract can provide significant clinical efficacy according to SCORAD and CDLQI questionnaire in children with atopic dermatitis. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the author.
Review and expert evaluation of the materials of the European meeting on hypersensitivity to drugs (DHM 2022)
Authors:   Shupyk National Healthcare University of Ukraine, Kyiv, Sharikadze O.V.
Published: February 2023

The review article discusses the current data on the mechanisms of hypersensitivity drugs reactions (HDRs). The relevance of the problem is associated with a significant prevalence of adverse drug reactions, in the structure of which immune allergic reactions occupy a significant proportion. Adverse drug reactions, according to the literature, occur in 10-20% of hospitalized patients and about 25% of outpatients. A serious problem of HDRs is their overdiagnosis, which affects the results of individual treatment and can have serious consequences in case of misdiagnosis, because it causes appropriate restrictions in the use of necessary drugs. Purpose - to analyze current views and recommendations on the problem of drug allergy; to highlight the issues of the 2022 meeting, which highlighted the problems of drug hypersensitivity. In particular, to show the relationship between viral infections and severe skin reactions, such as skin lesion syndrome with eosinophilia and systemic disorders. The article reviews and proposes algorithms that can be used to prevent the development of complications caused by HDRs. The materials of the article are based on the results of the European Meeting organized by the European Association of Allergists and Immunologists in 2022 in Verona, Italy. In the conclusions it is noted that despite the interest of the health care system and the large number of studies and publications on the problem of drug allergy, today there is an urgent need for accurate diagnostic approaches that will ensure the correct identification of the suspected drug by a combination of necessary tests and determine the cause for the possibility of prescribing appropriate treatment. The new mechanisms, phenotypes and endotypes of HDRs to drug responses discussed in the review are the future keys to preventing further exposure to harmful drugs. Preliminary pharmacogenomic screening (identification of specific human leukocyte antigen genotypes associated with severe skin adverse reactions) for patients of certain groups before prescribing high-risk drugs may become the future for Ukraine.

Purpose - to highlight the peculiarities of mortality of children in the first year of life (absolute number and level by individual causes and gender) in Ukraine in 2019-2020; to find out whether there have been changes during the year of the COVID-19 pandemic in the country that could hinder the achievement of the SDGs in the area of reducing child mortality. Materials and methods. The information base of the study was the official data from the State Statistics Service of Ukraine regarding the distribution of deceased children by sex, age groups, place of residence and causes of death in 2019-2020. For comparative analysis were used a data from the Statistics Poland and World Population Review (USA) databases. In the course of the analysis were used the following methods: systematic approach, bibliosemantic, epidemiological, statistical, graphical representation. Results. It has been shown that approximately 80% in the structure of mortality under the age of 1 year in Ukraine are accounted for by two main causes: certain conditions that occur in the perinatal period - 58.5% (in 2019 - 54%) and congenital malformations - 22.3% (in 2019 - 25%). The focus is on preventable causes (first of all, external causes and infectious diseases). In 2020 were reported six deaths under the age of 1 year due to COVID-19 firstly. Despite the decline in infant mortality in 2019-2020 from 7.0 to 6.7 per 1000 live births, indicates the likelihood of a negative impact of the COVID-19 pandemic on infant mortality in Ukraine, primarily as a result of the influence of indirect factors, and the need for actions to eliminate or minimize such influence. Conclusions. An analysis of the spectrum and weight of the contribution of the causes of death is a tool for determining the lines and scope of intervention to prevent them on the way to Ukraine achieving by 2030 the declared indicator of infant mortality in children aged 0-4 years old of 6.7 per 1000 live births.

The health of the oral cavity and cardiovascular system are closely related. Bacteria from the oral cavity can enter the bloodstream and cause infectious endocarditis (IE). Children with artificial valves or artificial material used during surgical procedures and cyanotic congenital heart defects (CHD) are particularly vulnerable. Purpose - to summarize literature data on the need of prevention of IE in healthy children and in children with CHD before dental interventions; to determine whether prophylactic antibiotic therapy should be routinely prescribed to children without CHD and children with corrected and uncorrected CHD. It is important to understand why IE affects particularly the valves. Bacteria spread with the blood stream and settle down on valves with a rough surface (prosthetic or anatomically altered). The peculiarity of the blood supply to the valves and the individual state of the patient's immune system determine the difficulty of fighting against the infection. According to the literature data, children with CHD are at greater risk of developing caries due to insufficient mineralization of primary tooth enamel, reduced saturation, and cardiac medications they take reduce salivation, thus increasing the risk of caries. Children with CHD and poor oral health have a high risk of developing oral bacteraemia and a greater risk of developing IE compared to children CHD and satisfactory oral health. Scientists concluded that, in fact, low-grade accumulative bacteremia is associated with daily brushing, flossing and chewing and is much more likely to cause IE compared to a one-time dental intervention. Therefore, it is concluded that maintaining optimal oral health plays a much more important role in reducing the frequency of IE than routine antibiotic prophylaxis for all dental interventions. Conclusions. Individual and professional hygiene and dental treatment should be carried out routinely for all children, regardless of age and concomitant pathology. Dental caries and its complications, as well as periodontitis serve as a potential source of bacteremia that threatens by the development of IE, which is simply - sepsis with a focus in the heart. Children who are not at risk of developing IE should not be routinely prescribed prophylactic antibiotic therapy. Instead, children with corrected and uncorrected CHD are at increased risk of developing IE and therefore require prophylactic antibiotic therapy during and after dental procedures.

Language Teachers’ Perceptions and Use of Extended Reality
Authors: Kaplan-Rakowski Regina , Papin Kevin , Hartwick Peggy
Published: February 2023

Extended reality (XR) is rapidly gaining attention and popularity; however, scholars confuse what XR technologies are and how they can be applied in language education. This qualitative, exploratory study unveils language teachers’ perceptions of XR, which is an umbrella term for virtual reality (VR), augmented reality (AR), and mixed reality (MR). Understanding teachers’ perceptions regarding XR is a necessary step toward successful integration, adaptation, and diffusion of these technologies. Based on 110 survey respondents and 10 focus group interviewees, we report on how language teachers apply XR and what potential benefits and barriers they face. This study contributes to the mutual understanding of XR in the computer-assisted language learning community, and it provides examples of practical applications of XR to facilitate language learning and teaching.

‘It came from China; it's a Chinese virus’
Authors: Lampropoulou Sofia , Cooper Paul , Pye Elizabeth , Griffiths Megan
Published: February 2023

This study examines the negotiations of racism by Twitter users in the representation of the COVID-19 crisis during the first wave of the pandemic. We focus on expressions that target China as the place where COVID originated such as ‘Chinese virus’ and ‘Kung flu’. The repeated use and discussion of these terms on social media serves to create, establish and reinforce indexical links (Silverstein 2003) to social values, which relate to ideological conceptions of China and Chinese culture. Additionally, Twitter users’ crisis processing involves the renegotiatation of indexical links to social values that coincides with the engagement in sociopolitical debates that frequent online media environments, resulting in sociological fractionation (Agha 2007); the ideological opposition between Twitter user groups involves statements such as ‘Kung flu is racist but COVID originated in China's dirty markets.’ We see such disclaimers as examples of ‘liquid racism’ (Weaver 2011) that, while they are difficult to pin down as racist, they naturalise Sinophobia as the dominant discourse in our dataset. We conclude that racism in our data is a resource embedded in blame attribution that is compatible with crisis processing.

Should we teach students how to bullshit?
Authors: McEachern Peter J , McEachern Robert W
Published: February 2023

Bullshit, as defined by Frankfurt (2005, p. 10), is language that is “disconnected from a concern for the truth.” Much scholarship shows that bullshit is a prominent feature in organizations that is difficult, if not impossible, to get rid of (e.g., McCarthy et al., 2020; Penny, 2010). Bullshit, by definition and by cultural practice, seems antithetical to business writing orthodoxy. As Thill and Bovée (2020) suggest in a representative textbook, communication should be clear and ethical. However, Spicer (2020) codifies bullshit as a social practice whose outcomes are not always dire. Well-crafted bullshit benefits its users, allowing them to “fit into a speech community, get things done in day-to-day interaction and bolster their image and identity” (Spicer, 2020, p. 20). Contrasting with business writing’s abstinence-only bullshit stance, this suggests that successful writers must adapt to their organization’s speech act practices. In this article, we argue that students must be taught about bullshit. After describing bullshit and its role in organizations, we show how business writing could incorporate a critically informed approach to bullshit in undergraduate courses, internship preparation courses, and other curricular instances in which students work directly with organizations. While bullshitting should not be outright encouraged, continued ignorance will do nothing to solve its associated problems. Promoting bullshit literacy, however, could both minimize bullshit’s harms and maximize its benefits. We close by describing how this approach could foster critical thinking skills, promote more seamless adaptation to organizational cultures and communication practices, and perhaps even improve mental health outcomes.

The COVID-19 pandemic is having a severe impact on the economic situation. In Poland, the course of the crisis so far is considered to be quite mild from the perspective of the entire labour market. However, many people have lost their jobs as a result of redundancies. Many industries have suffered despite the protective measures taken up by the Polish legislator in order to limit the possibility of job cuts. Some employers whose financial situation had deteriorated had to reduce employment. This resulted in layoffs for reasons not related to the employees. The legal basis is regulated by the Act of 13 March 2003 on special rules for terminating employment relationships with employees for reasons not related to employees.
Ethical Challenges in Forensic Social Work
Authors: Reamer Frederic
Published: February 2023

Many social workers become involved in legal proceedings on their clients’ behalf. A subset of practitioners identify themselves as forensic social workers. Forensic social work is typically defined as the application of social work knowledge and skills to questions and issues relating to law, legal institutions, and legal proceedings. This social work specialization often entails collaboration with other professionals, especially attorneys, on clients’ behalf. This collaboration sometimes leads to ethical dilemmas, especially related to commitment to clients; informed consent; client confidentiality and privileged communication; conflicts of interest; and interdisciplinary collaboration. The purpose of this article is to identify common ethical challenges in forensic social work; apply relevant social work ethics standards; discuss risk management models and protocols to protect clients and practitioners; and discuss potential ethics challenges when forensic social workers are subpoenaed during legal proceedings.
Pseudo-minimal surfaces of revolution

Published: February 2023

This paper is a follow-up to the first author’s series of works about shape modeling of orthotropic elastic material that takes the equilibrium form inside the area with the specified boundaries. M.S. Bukhtyak, in a number of his publications of 20162020, proposed an approach to the model building based on the application of surfaces with a constant ratio of principal curvatures. These surfaces are named pseudo-minimal surfaces. The theorem of existence has been demonstrated and the finitely-element model has been built. The condition distinguishing the class of pseudo-minimal surfaces, as applied to ruled surfaces, is either satisfied identically (trivial subclasses) or is satisfied along a family of lines. The corresponding classes of ruled surfaces have been comprehensively characterized geometrically. A partial differential equation that defines (in the local sense) the class of pseudo-minimal surfaces is very complex for analysis, which makes it relevant to consider approximate solutions. The current paper considers the pseudo-minimal surfaces of revolution. Generation of the approximate solutions is complicated by the tendency of the formal Taylor polynomial to diverge.

Fundamental inefficiency of existing foam fire systems extinguishing tanks with oil and petroleum products having a volume of 5000 m3 or more is shown by methods of mathematical modeling. The required foam supply intensity and foam supply rate allowing effective fire suppression in large tanks with a volume of up to 20000 m3 are theoretically predicted. On this basis of theoretical conclusions, a new method of foam fire extinguishing in large fuel tanks has been developed. To obtain the required intensities and supply rates, fire extinguishing foam is formed in a special container with the use of solid-fuel gas generators. The theoretical predictions were confirmed in 21 full-scale successful experiments, in which fire suppresion system based on the new method was able to extinguish a fully developed gasoline fire in tanks with a volume of 5000 m3 and 20 000 m3 just for 30-90 seconds. The required amount of the foaming agent to extinguish a fire in a 20 000 m3 tank is only 450 liters, which is at least 100 times less than for traditional foam fire fighting Contribution of the authors: the authors contributed equally to this article.

An experimental mechanism for cleaning grain mixtures with a drive from a linear asynchronous electric motor has been developed and manufactured in the Bashkir State Agrarian University. More favorable conditions for sifting the grain mixture are created as a result of the use of an asynchronous linear electric motor for its drives in comparison with traditionally used machines driven by rotation motors. Based on the Lagrange equations, a mathematical description of the movement of the links of the mechanism is carried out and the electromagnetic force required in accordance with the cleaning technology is found. It is created in the windings of a linear electric motor by an electronic switch. It is found that the shape of the pulse of the required electromagnetic force is close to sinusoidal. However, it is possible to replace the electromotive force varying according to the sinusoidal law by a force constant in modulus and equal in impulse.

This work presents a study of the preparation of additive materials based on a nickel-chromium alloy of the Ni-Cr-CrN system by direct metal laser sintering (DMLS). The additive materials were produced on the EOS M270 setup (with the option of open editing modes). The research range: laser radiation from 100 to 200 W, the speed of the laser beam from 600 to 1100 mm/s. The chemical composition of the obtained materials is investigated. The composition indicates a high final content of nitrogen in the alloy (0.5%). The structure of the obtained samples and their mechanical characteristics, namely, the bending strength (1500 MPa) and Vickers microhardness (450 HV), have been investigated. The morphology, microstructure, and elemental analysis of the initial powder and the resulting additive materials were studied by scanning electron microscopy and X-ray spectral microanalysis on the TESCAN Vega research complex. Analysis of the structure shows that the elements Ni, Cr and Fe are distributed evenly over the entire area of the samples, which indicates a uniform Ni-Cr-CrN melt.

Calculation of a stepped rod under longitudinal-transverse bending with discrete axis loading
Authors:   Penza State University of Architecture and Construction, Bakushev Sergey V.
Published: February 2023

This paper aims at obtaining formulas for bending moments and shear forces in a rectilinear elastic stepped rod under plane longitudinal-transverse bending. Each step of the rod (segment) can consist of different materials and have its own shape and cross- sectional dimensions. The rod can be loaded by an axial longitudinal force at the beginning of each step. The eccentricity of longitudinal forces at the beginning of each step (segment) is taken into account, which occurs due to the mismatch of longitudinal axes at the current and previous steps. Each segment of the rod can be exposed to a transverse action represented as concentrated bending moments, concentrated forces, and uniformly distributed loading. The resulting algebraic equations of the bending moments and shear forces are obtained for the stepped rod under longitudinal-transverse bending. The numerical model has been considered. The study results show that allowance for longitudinal action on the stepped rod bending with discrete axial loading leads to an increase in the ordinates of epures and bending moments, as well as in shear forces as compared to transverse bending caused by transverse loading only. Moreover, the internal transverse forces do not remain constant on the rod segments which are free from uniformly-distributed transverse loading. The obtained formulas for bending moments and transverse forces can be applied in calculations of elastic stepped rods under longitudinal-transverse bending.

In this work, mathematical modeling of relative dynamics of a bifullerene complex is carried out on the assumption that the inner shell does not form covalent bonds with an outer carbon skeleton. This fact enables free angular movements of the inner shell. In particular, the directed rotation of the inner fullerene can be provided. This, in turn, allows for accumulating of a significant fraction of kinetic energy at internal degrees of freedom of the complex under consideration. In this case, the direction of rotations is not related to temperature; the outer shell of the complex restrains the transfer of the stored energy into thermal vibrations. Therefore, calculations are performed to estimate the stability of the rotational motion of an encapsulated fullerene relative to translational displacements of the outer shell. The calculations are carried out using a separate description of the dynamics of closed carbon molecules in terms of translational and rotational displacements. Translational displacements are determined using the equations of motion for the centers of mass of molecules. Rotational displacements are found on the basis of the dynamic Euler equations. The power centers in the considered framework structures of the molecules are carbon atoms. Therefore, the strength characteristics of intermolecular interactions are obtained in accordance with an atom-atom approach. In this case, the interaction parameters of individual atoms correspond to the case when these atoms are located in a structure of the surface carbon crystal.
Determination of the elastic fields induced by body forces in transtropic bodies of revolution

Published: February 2023

The paper presents a method for determining the stress-strain state of transversely isotropic bodies of revolution under the action of non-axisymmetric stationary body forces. This problem solution involves the use of boundary state method definitions. The basis of the space of internal states is formed using the fundamental polynomials. The polynomial is placed in any position of a displacement vector of the plane auxiliary state; the spatial state is determined by transition formulas. A set of such states forms a finite-dimensional basis, in which after orthogonalization, the desired state is expanded into Fourier series with the same coefficients. The series coefficients are scalar products of the vectors of given and basic body forces. Finally, the determination of the elastic state is reduced to solving quadratures. The solutions to problems of elasticity theory for a transversely isotropic circular cylinder are analyzed in terms of the action of body forces given by various cyclic laws (sine and cosine). Recommendations are given for constructing the basis of internal states depending on the type of the function of the given body forces. The analysis of the series convergence and the estimation of the solution accuracy are given in a graphical form.
