Authors: Boykina E.E. , Chirkina R.V. , Chumachenko D.V. , Romanova N.M. , Kiselev K.A.
Published: April 2024

The article provides data on the standardization of the methodology “Ostracism Threatened Needs Scale (Adolescent, Youth), OTNS-AY (in Russ.)”, which is a modification of the “Need Threat Scale” methodology (I. van Beest, K.D. Williams, 2006). In the Russian version, OTNS-AY is represented by four subscales: the need for belonging, self-esteem, control and meaningful existence. The study involved 2351 people aged 14 to 25 years (M = 18.4 years, SD = 2.59). Distribution of the sample by gender: male 23.9%, female 75.8%. To assess the internal consistency of the questionnaire subscales, Cronbach’s Alpha consistency assessment was used, which showed good consistency of all 4 subscales: “belonging” (0.83), “selfesteem” (0.80), “control” (0.84) and “meaningful existence” (0.84). The general model of the four first-level factors and two second-level factors questionnaire was tested using confirmatory factor analysis, which showed good fit to the data: SRMR=0,046; CFI=0,99 RMSEA=0,043. To assess external validity, the questionnaires “Diagnostics of Affiliation Motives, A. Mehrabian (in Russ.)”, “Rosenberg Self-Esteem Scale (in Russ.)” and “Purpose-in-Life Test by D. Leontiev (in Russ.)” were used. The appendix to the article contains the text of the OTNS-AY (in Russ.) with instructions, key and interpretation.

Authors: Tukhtaeva D.A. , Lukovtseva Z.V.
Published: April 2024

The relevance of the study is determined by the contradictory ideas about the psychological characteristics of people who experienced sexual violence in childhood or adolescence. The study was exploratory in nature and had no hypothesis. The sample consisted of 40 adults with experience of sexual violence at the specified ages. Interviews, “Traumatic Stress Questionnaire”, “Unfinished Sentences”, "Time Perspective Questionnaire”, “Auto- and Heteroaggression Questionnaire”, “Self-Attitude Research Methodology” were used. The relationships between the values were evaluated according to the scales of the methods (Spearman’s r, p≤0.01). The inconsistency and vulnerability of self-attitude, the severity of depressive and anxious experiences, the psychological alienation of the past, and the negative perception of relationships with parents came to the fore. The emotional-protective role of the mnestic-attentive decrease is determined, the resource features of self-attitude and relationships with others are revealed. The importance of further studies of victims of different gender, age and nosological affiliation, as well as comparing the information obtained with the characteristics of victims who did not seek professional help, is substantiated.
Raising the Question of Law in Language
Authors: Rekosh K. Kh.
Published: April 2024

The article shows a different approach (compared to the traditional one) to the paradigm of a public institution and to the development of a new epistemology, which replaces analysis (understood as a decomposition in the greek meaning of the word) and promotes synthesis and holism in the interpretation of law in language. It emphasizes that there are relationships between a public institution (law), language and cognition, where the role of language requires special study, especially in relation to mental activity. Modern scientific interdisciplinary approaches lead us to consider this phenomenon in the light of the paradigms of cognitivism (In connection with the interrelation and inseparability of language from thinking) and fractal semiotics (taking into account the “biosocial” function of language and the construction of an object of study from the position of an observer), representing these two public institutions as procedural, self-referential, self-organizing in their interaction with an observer.
Preliminary Implications of Viscoelastic Ray Theory for Anelastic Seismic Tomography Models
Authors: Borcherdt Roger D.
Published: April 2024

The recent developments in general viscoelastic ray theory provide a rigorous mathematical framework for anelastic seismic tomography. They provide closed-form solutions of forward ray-tracing and simple inverse problems for anelastic horizontal and spherical layered media with material gradients. They provide ray-tracing computation algorithms valid for all angles of incidence that account for changes in wave speed, attenuation, and trajectory of anelastic P and S body waves induced by anelastic boundaries. They account for theoretical predictions that seismic waves refract as inhomogeneous waves across anelastic boundaries for all angles of incidence, which in turn accounts for energy carried by plane waves along seismic boundaries at head wave critical angles and wide-angle refracted (WAR) ray paths that are not predicted by elastic models. Exact viscoelastic ray-tracing numerical results for various models provide examples that illustrate the effects of anelastic boundaries on the travel times and amplitudes of seismic waves. They show the effects are strongly dependent on angle of incidence. For near-critical and wide angles of incidence the anelastic effects on travel times and amplitudes can be large and are not explained by elastic ray theory, but the effects on travel times can be relatively small and difficult to distinguish from those for elastic media for pre-near-critical angles of incidence. The results for some models indicate that reflected anelastic WAR waves may be observable at the surface and possibly account for some prominent seismic arrivals not explained by elasticity. These preliminary results suggest that the application of exact viscoelastic ray-tracing computation algorithms to exploration and teleseismic data sets can reveal new insights regarding the properties and distribution of anelastic materials in the Earth.
Ustekinumab or vedolizumab for refractory metastatic Crohn's disease?
Authors: Kurt İdris , Tezel Hüseyin Ahmet
Published: April 2024

Metastatic Crohn's disease is a rare skin manifestation of Crohn’s disease. A variety of treatment options are available for this condition. But there is a lack of clarity regarding the treatment of resistant cases. There is ongoing debate as to which agent should be selected (vedolizumab or ustekinumab) in patients that are not responding to anti-tumor necrosis factor agents. This study identifies a unique patient who has developed a disease (metastatic Crohn's disease) under treatment with vedolizumab. Following treatment with ustekinumab, the patient regressed completely. Therefore, we recommend ustekinumab primarily in metastatic Crohn's disease.

Published: April 2024

Parsley is a condiment produced mainly by small producers, often in the organic system. Organic fertilizers make nutrients slowly available to plants when compared to inorganic fertilizers, an important quality for phosphorus (P), which is a nutrient that tends to fixate and adsorption. Thus, the objective of this work was to evaluate the production of parsley with the use of organic sources of phosphorus in different proportions. Fourteen treatments were evaluated, resulting from the factorial 6 x 2 + 2: six proportions of two phosphate fertilizers (thermophosphate Yoorin® (TY) and bone meal (BM)), two doses (recommended (180 kg.ha-1 of P2O5, and double this) + two controls (without phosphate fertilizer; and with inorganic triple superphosphate fertilizer (recommended dose)). The proportions were: 100% P with TY; 80% P with TY + 20% with BM; 60% P with TY + 40% with BM; 40% P with TY + 60% with BM; 20% P with TY + 80% with BM; 100% P with BM. Shoot height, number of leaves, fresh and dry weight of leaves in two harvests and the total of these two harvests were evaluated. No significant differences were obtained in the two harvests. The lack of effect to phosphate fertilization may be related to the high initial P content in the soil (123 mg.dm-3), which shows that in this case, fertilization with this nutrient is not necessary to produce parsley, despite the official recommendation to fertilize with phosphorus in a soil with a high P content.

This study aims to explore the roles of AI in order to support the development of HIMS. We conducted a literature review by extracting the articles from PubMed, ProQuest, and Google Scholar in the past 5 years (January 2019-August 2023) using specific keywords. The full text of relevant articles then thematically synthesized and to be presented. Our findings revealed eight themes that represent the role of AI in supporting the hospital information management system and its implementation in healthcare settings. The themes identified include Diagnosis and Medical Imaging, Health Data Management, Risks Prediction and Disease Progression, Inventory and Procurement Management, Telemedicine and Remote Consultation, Patient Care Management, Drug Development and Clinical Research, and Hospital Data Security System. The AI implementation brings the potential to improve efficiency, accuracy, and quality of care in hospitals. However, it should be noted that the development and implementation of AI need to consider the ethical aspects and proper integration through existing health systems.
Finite element analysis-A biomechanical tool in orthodontics
Authors: Gandhi Anshika , Singh Deepak , Fatima Kaleem , Tripathi Tulika , Rai Priyank
Published: April 2024

In orthodontic research, the finite element method (FEM) has been widely used as an engineering resource for calculating the stress and deformation of complex structures. Applying the FEM can predict the graphic representation of these tissue responses through the observation of areas of stress created by applied orthodontic mechanics. This method has the advantage of being non-invasive, accurate, and providing quantitative and detailed data on the physiological reactions possible to occur in tissues. The purpose of this article is to review and discuss the steps involved in applying the concept of finite elements and how they can be used in orthodontics. The stress distribution at the interface between the alveolar bone and the periodontal ligament, as well as the shifting trend in different tooth movement types while employing different kinds of orthodontic devices, may both be assessed using FEM. For this reason, expertise with certain software is required. Despite the drawbacks of other experimental techniques, FEM is a crucial technique for addressing inquiries regarding tooth movement.

Authors: Agrawal Surabhi , Chachada Achint , Jain Megha , Golchha Rishabh
Published: April 2024

To evaluate and compare the effects of manual tooth brushing and powered tooth brushing on biofilm formation on metal orthodontic brackets and on gingival and periodontal health of the patient undergoing orthodontic treatment.

This randomized controlled clinical trial comprised a total of 36 patients in the age group 15-25 years, coming to Outpatient Department (OPD) of Orthodontics and Dentofacial Orthopedics and undergoing orthodontic treatment. Periodontal evaluation was performed for each patient at four intervals of time, before oral prophylaxis, 1 week after oral prophylaxis, after 3 months of bonding and after 6 months of bonding which constituted the readings at T, T, T and T, respectively. Patients were instructed to use manual toothbrushes for 3 months after bonding. Post 3 months, the patients were divided into two groups- Group I and II as Group I- patients using powered toothbrush and Group II- patients using manual toothbrush, for next 3 months. At both the intervals (T and T), two brackets were debonded from central incisors and second premolars from each patient and studied under scanning electron microscope for biofilm formation.

Powered toothbrushing was more effective in reducing API and SBI scores, statistically high significant difference was seen in API score (P = .004) and SBI score (P < .001) between T & T time intervals on comparing both the groups. Both the manual and powered toothbrushing had equal effect on GI scores, no significant difference was seen in GI score (P = .540) between T & T time intervals on comparing both the groups. On inter group comparison of amount of biofilm formation between T2 & T3 time intervals in anterior and posterior region, higher amount of biofilm formation in both the anterior and posterior regions in group II patients (Anterior region= 12.05±6.90, P = .001, posterior region= 10.32±9.75, P = .001).

Powered toothbrushes are more effective in removing plaque and thus reducing gingival inflammation in patients with fixed orthodontic appliances.

Published: April 2024

Maxillary canines are one of the most common impacted teeth. The objective in localization of an impacted canine is to be able to decide such a radiographic technique which has minimal radiation dose, cost and minimum superimpositions. Panoramic radiograph, being a screening radiograph, can satisfy the above needs. Taking this into consideration, the present study was done to evaluate the reliability of panoramic radiograph in localization of impacted permanent maxillary canines, when compared to cone-beam computed tomography.

OPG and CBCT images of 100 maxillary impacted canines were included in the study irrespective of site. Each OPG was evaluated for vertical angulation and the data obtained was tabulated and subjected to statistical analysis.

In the present study, the female to male ratio was 2.57:1, with a slightly higher prevalence of impacted maxillary canines on left side. The results of the present study show a 100% concordance between OPG and CBCT for palatal and buccal impactions, and 91% for mid-alveolus impactions.

Based on the results of the present study, it may be concluded that panoramic radiographs are useful for predicting the location of impacted maxillary canines against the confirmatory radiographic modality like CBCT.
W potrzasku strachu i propagandy – polskie teatry we Lwowie 1939–1941
Authors: Horbatowski Piotr
Published: April 2024

Artykuł przedstawia sytuację, w jakiej znalazł się teatr polski i ludzie teatru w czasie sowieckiej okupacji Lwowa w latach 1939–1941. Władza sowiecka dążyła do dyskredytacji polskiej kultury narodowej, odcinając ją od korzeni i próbując zbudować, nową, obcą narodowej tradycji, polską kulturę radziecką. Teatr polski został tym samym właczony do poczynań propagandowych, zgodnych z celami okupującego go państwa. Reżim sowiecki zastawił na polskich artystów zręczną pułapkę. Z jednej strony wzbudzał strach, stosując represje wobec wszystkich Polaków, z drugiej — otaczał ludzi teatru względnym parawanem bezpieczeństwa, traktując liberalniej niż pozostałych mieszkańców. W artykule zostały przedstawione różne postawy ludzi teatru: od skrajnie oportunistycznych, poprzez bierne uczestnictwo w działaniach propagandowych, aż po heroiczne próby przeciwstawienia się okupantowi. Te ostatnie były charakterystyczne dla inicjatyw konspiracyjnych, organizowanych najczęściej w lwowskich kościołach katolickich. W artykule uwzględniona została zarówno działalność teatrów profesjonalnych, jak i amatorskich.

Artykuł podejmuje problematykę zaangażowania środowiska teatru w sprawy publiczne w okresie od wyborów czerwcowych i poprzedzającej je kampanii wyborczej do upadku rządu Tadeusza Mazowieckiego w grudniu 1990 r. Środowiskowi liderzy opinii gremialnie poparli kierunek transformacji systemowej zaproponowany przez rząd „naszego premiera”. Starzy mistrzowie (Gustaw Holoubek, Andrzej Łapicki, Andrzej Szczepkowski, Andrzej Wajda) wystartowali spod szyldu „Solidarności” w wyborach czerwcowych, zaś I. Cywińska – dyrektorka kontestatorskiego Teatru Nowego w Poznaniu – została ministrem kultury i sztuki w gabinecie Mazowieckiego. Czołowe postaci życia teatralnego były zwolennikami tak samego premiera, jak i jego zaplecza politycznego. W artykule uwypuklono przejawy działalności publicznej ludzi sceny, służące do tego środki wyrazu czy też fora, gdzie taką praktykowano. Środowisko teatralne, przyzwyczajone do stylistyki teatru aluzyjnego — tak specyficznej dla PRL, nie do końca umiało odszukać się w warunkach rodzącej się demokracji liberalnej.
Influence of Structural Discontinuity on Slope Stability using Numerical Modelling and Sirovision
Authors: Raja S. , Murthy Ch. S. N.
Published: April 2024

The rock mass consists of heterogeneous and anisotropic materials, with smaller and larger blocks of rock, and the presence of structural discontinuities is a significant concern. Characterising the rock mass is crucial for the success of engineering excavations in such areas. A detailed study of joints, their orientation, and discontinuities in the exposed rock mass is crucial as they greatly influence stability and fragmentation. Existing rock mass classifications like Rock Mass Rating (RMR) and Q-classification require various geological parameters and physico-mechanical properties of the rock. However, determining these parameters conventionally can be time-consuming, requiring careful on-site measurements. The number of opencast coal mines is increasing compared to underground mines due to shorter gestation periods, higher productivity, and quicker returns. However, opencast mining raises environmental concerns such as air and water pollution, solid waste management, land degradation, and socio-economic issues. Additionally, many opencast coal mines, regardless of size, are reaching greater depths, making analysing bench slopes and ultimate pit slope design crucial. Slope failure in these mines leads to production loss, additional costs for recovery and handling of failed material, pit dewatering, sometimes mine abandonment or premature closure, and loss of life. A study was conducted at Prakash Khani Opencast Mine – IV, Manuguru area, M/s The Singereni Company Collieries Limited (SCCL), to investigate the influence of structural discontinuities on slope stability. SIROVISION software was used to assess rock mass characterisation, while PLAXIS-2D software was employed to analyse the influence of structural discontinuities on slope stability. A comparative conclusion was drawn based on the results obtained from SIROVISION and PLAXIS-2D analyses. The study revealed that the RMR of the mine ranged from very poor to fair due to numerous discontinuities. It was also found that discontinuities in the slope decrease the Factor of Safety (FOS), indicating an impact on slope stability.

Authors: Prakash Satya
Published: April 2024

Tungsten carbide inserts in rock drill bits are predominantly used in drilling rocks, particularly in mining industries. The research studies performed on drill bits have been limited to several factors such as collecting failure data of bit components from the field, conducting wear tests considering rock properties, and introducing new coated insert materials. The role of Artificial Intelligence (AI) and Machine Learning (ML) for the betterment of tool wear with real-time data is limited. The present study has offered an evaluative perspective of an essential industrial issue. In this review, a concept map presents a visual organization and representation of knowledge obtained during the study. Utilizing the propositions from the concept map, a brief review of the integrated concepts of researchers relating drill bits, failure data, numerical and statistical models, wear analysis, reliability assessment, and prerequisites in developing new materials have been discussed in the backdrop of the present study.

Ayurveda considered Alopecia areata as a minor ailment but now in this era of presentation looks are very important. Everyone wants to be beautiful and attractive. Hairs and skin are the mirror of beauty. If these two things are healthy and beautiful then the person looks more beautiful. An 18-year-old boy came to OPD with patches of baldness over his scalp. He has taken ‘n’ no. of treatment modalities for Alopecia areata but the results were not mesmerizing. The patient was advised to do microneedling with cupping for his baldness. According to the Pull and Tug test and SALT criteria, the patient had a 40% area of baldness at the center. After obtaining consent, the procedure was done thrice in 15 days. Along with this, internal medication with local application of oil was going on. In Internal medication, Asthimajja pachak (herbal drug combination), Praval Panchamrit (sea-origin calcium supplement), and Krumikurthar rasa (herbs-mineral drug) were given. After 4 months, with 15 sitting of microneedling with cupping, the patient had normal and healthy hair growth. Micro-needling along with internal medication is the best, cost-effective, and less invasive solution for re-growing hairs over high-cost hair treatments and transplantation.

Objective: Investigation of hepatoprotective activity of Gyrocarpus asiaticus Willd (GA) and Lactuca runcinata DC (LR) prepared by hydroalcohol extraction. Methodology: Albino rats were used for the in vivo experiments for the determination of oral acute toxicity study. For these experiments, 6 groups were created of which 5 groups were for each plant extract and 1 group for control. A total of 11 groups were made for the toxicity study. Each group required 2 albino mice. Different doses of 0.025, 0.2, 0.5, 2, and 5 gm/kg body weight were administered orally for each plant extract. For the control group, these were administered with distilled water. For hepatoprotective activity, albino rats were randomly divided into 5 (control, toxic, standard, 2 samples) groups, and 4 animals were randomly divided into each group. For 2 plants, a total of 7 groups were made. 5% gum acacia was used as the vehicle. For induced hepatotoxicity CCl4 and as a standard drug silymarin was used. Result and Discussion: Plant extracts did not show any toxicity, and no histopathological changes were seen in the liver, kidney, or lungs due to toxicity. In the study of GA Willd and LR DC extract prepared by hydroalcohol solution, there was evidence of protection against CCl4-induced hepatotoxicity in the Histopathological study of the liver of albino rats. Conclusion: Hydroalcohol extract of LR DC and GA Willd shows no oral acute toxicity and LR DC shows no significant hepatoprotective activity but GA Willd shows significant hepatoprotective activity
Atypical forms of state structure: the example of an empire
Authors:   Togliatti State University, Skvoznikov A. N.

In the science of the theory of state and law, a problem related to the classification of forms of state structure has arisen. The traditional approach to the form of state structure, within which it is customary to distinguish unified (unitary) and constituent (federal) states, does not reflect contemporary life realities. There are no clear criteria in legal science for dividing states into unified and constituent ones. The paper considers various approaches to the problem of classifying forms of state structure in contemporary legal theory. The author concludes that the traditional three-element approach to the form of state (form of government, form of organization and political regime) has methodologically exhausted itself and does not reflect the current state of affairs. All elements of the state form are closely interrelated and are in an unbreakable dialectical unity. The form of government largely determines the form of the territorial structure, as well as the methods of interaction between the authorities and the population (political regime). The nature of the relationship between the center and the regions (constituent entities) based on the centralization or decentralization principle, largely depends on the form of government. As a rule, the republican form of government determines the federal (decentralized) form of state-territorial structure and the democratic political regime. At the same time, the real possibility of functioning of republican institutions (election and alternation of government authorities) and the implementation of the federalism principles (the actual independence of the constituent parts of the state) largely depend on the political regime. In the context of an authoritarian (totalitarian) political regime, the republican form of government and the federal form of government enshrined in legislation are conditional in nature – in fact, they cannot be implemented. The purpose of the work is to analyze the forms of state structure in contemporary legal theory and identify the essential features of empire as a special form of state structure.

Unsatisfactory quality of the surface layer of additive products, in particular increased surface roughness, prevents the widespread use of electron beam powder bed fusion (EBPBF). Electrospark treatment (EST) is one of the methods for smoothing and hardening the surface layer. The work shows the possibility of modifying the surface of additive VT6 alloy samples by reactive EST with multicomponent electrodes. For this purpose, the authors used electrodes made of the Fe48Cr15Mo14Y2C15B6 bulk metallic glass forming alloy and the FeCoCrNi2 high-entropy alloy. Based on the results of scanning electron microscopy, it was identified that after EST, both modified layers have a thickness of about 16 μm. X-ray diffraction phase analysis showed that in the case of treatment with an amorphous electrode they contain carboborides of the Ti(B,C) type, and in the case of treatment with a high-entropy electrode – intermetallic of the Ti2(Fe,Ni) type. The modified layers have average hardness values of 19 and 10 GPa and elastic modulus of 234 and 157 GPa, respectively, which significantly exceeds the values of these parameters for the EBPBF-grown VT6 alloy. Electric discharge modification of the surface with multicomponent electrodes led to a decrease in roughness by 8...11 times due to the melting of the protrusions and filling of the dimples with the melt to a depth of more than 50 μm. A comparative analysis of the results of tribological tests showed a change in the wear mechanism as a result of EST of the additive VT6 alloy. Wear resistance increased by 4 and 3 orders of magnitude when using electrodes made of a bulk metallic glass and high-entropy alloy, respectively.

The paper presents the results of the study of the end milling temperature of low-alloy steel depending on the cutting modes and the type of crystalline structure. The experiment was carried out on a PROMA FHV-50PD universal milling machine. The blanks were processed using a 12-12D-30C-75L-4F HRC55 carbide milling cutter. No cooling was used during processing. The obtained data were statistically analyzed to identify the dependence of the end milling temperature of low-alloy steel on the processing modes and the steel crystalline structure. When creating a mathematical model of cutting temperature, the authors carried out a bootstrap analysis to identify the significance of the parameters of the processing modes. The mathematical model was chosen using the Akaike informative criterion. It was found that mathematical models of the temperature dependence on processing modes for both types of crystalline structure include the cutting depth in the second power. At the same time, for steel in an ultrafine-grained state, both the cutting depth and the feed are statistically significant. It was not possible to detect the influence of cutting speed on temperature in the studied range of processing modes. Thus, when milling this group of materials, the force component primarily determined by the cutting depth exerts the predominant influence on the temperature regime. The level of cutting temperature when processing steel in an ultrafine-grained state is generally higher than when processing steel in a coarse-grained state, which should be associated with the increased physical and mechanical properties of steel with an ultrafine-grained crystalline structure.

Процедура признания предприятия банкротом является крайне важным и ответственным этапом в жизни компании. Когда фирма оказывается в серьезных финансовых трудностях, банкротство может стать необходимым стратегическим решением для ее выживаемости. В случае, если компания накопила значительные долги и не имеет возможности их погасить, банкротство становится единственным выходом из ситуации. В рамках этой процедуры все активы и имущество предприятия будут проданы на аукционе, чтобы погасить долги перед кредиторами. В случае недостатка средств, некоторые долги могут быть аннулированы. Процедура банкротства юридического лица имеет прямое влияние как на интересы самой компании, так и на интересы лиц, имеющих претензии к ней. Законодательство направлено на то, чтобы мотивировать руководителей активно защищать интересы предприятия, иначе они могут быть признаны виновными в банкротстве компании еще до начала процедуры. Это означает, что руководство должно предпринимать все возможные меры для предотвращения банкротства и минимизации его последствий. В данной статье мы рассмотрим важность этой процедуры, ее основные этапы, виды и в каких случаях стоит начинать процедуру банкротства, а также последствия для предприятия, сотрудников и кредиторов.
