Clinical and neuroimaging aspects of formal thought disorder in schizophrenia: a brief narrative review
Authors: Levada O. A. , Troian O. S.
Published: July 2024

Aim. To analyze current sources regarding the clinical and neuroimaging aspects of formal thought disorder (FTD) in patients with schizophrenia to create an up-to-date pathogenetic model of its main forms.
Materials and methods. English-language publications in the Medline database (PubMed) were analyzed for this review. We analyzed only structural magnetic resonance imaging (MRI) studies in which a clear clinical assessment of FTD in schizophrenia is provided and the neuroimaging protocol meets generally accepted standards (as in the ENIGMA Schizophrenia Working Group). For the clinical division of FTD, positive and negative FTD were distinguished according to the positive and negative syndrome scale (PANSS).
Results. From a clinical point of view, FTD includes at least 30 phenomena. For clinical and neuroimaging studies, division into positive and negative FTD is used according to the PANSS. Positive FTD is manifested by the disorganization of thinking processes and exhibits mainly in violations of its purposeful sequence. Negative FTD is manifested by violations of the abstract-symbolic way of thinking, lack of spontaneity, and stereotyping. According to morphometric MRI data, atrophic changes in brain regions related to neuronal networks of cognition and impulse control (prefrontal and anterior cingulate cortex), emotional processing (amygdala), abstract thinking, and imagination (lateral occipital cortex) are important for the development of both forms of FTD. Negative FTD is mainly associated with damage to the prefronto-cingulate circles, which are the anatomical and functional substrates of executive functions. A unique feature of positive FTD is atrophy of the structures of the left temporal lobe, which leads to language disorders at the semantic level. Using the method of virtual histology, it was established that both forms of FTD are associated with bilateral changes in astrocytes and dendritic spines in the involved anatomical regions. A positive FTD is also associated with pathological changes in microglia in two hemispheres, while with a negative FTD, microglial damages are present only in the right hemisphere.
Conclusions. Positive FTD in schizophrenia is mainly associated with atrophic (astroglial-microglial) processes of cognitive control networks, negative – with the atrophy of networks of semantic processing of verbal information. In both forms, networks of emotional processing, abstract thinking, and imagination are involved. Treatment strategies for FTD should include effects on astroglial and microglial dysfunction.

Endothelial dysfunction is characterized by a decrease in the bioavailability of the vasodilator – nitric oxide (NO), and an increase in the level of vasoconstrictor substances. This imbalance leads to vasoconstriction, leukocyte attachment and inflammatory reactions in the vascular wall, atherosclerosis and thrombosis.
The aim: to evaluate the role of adipose tissue elements in the regulation of parameters of the nitroxidergic system under hypoxia conditions.
Materials and methods. The studies were carried out on 30 adult white male Wistar rats. All animals were randomly assigned and divided into groups: a control group (15 rats), type 2 diabetes mellitus (T2DM) was induced in the animals of the second group (15 rats). Isolated fragments of the popliteal arteries (PA) and intrapulmonary artery (IPA) were cleared of perivascular adipose tissue (PVAT-) or left uncleaned (PVAT+) and cut into rings. The simulation of acute hypoxia with further study of medical agents were performed.
Results. The PA and IPA with PVAT responded to acute hypoxia with vasoconstriction – an increase in the amplitude of contraction in the first and second phases, and after removing PVAT, they responded with a decrease in the maximum amplitude of contraction by 3.4 times in the 1st phase and an increase in amplitude by 1.8 times in the 2nd phase. Perfusion with Angiolin reduced 2nd phase of HV of the PA and IPA. Adding a combination of Thiotriazoline and L-arginine (1:4) to a solution for perfusion of fragments of arteries of animals with T2DM, causes a significant increase in constrictor reactions in both the 1st and 2nd phases of HV, regardless of presence of perivascular adipose tissue.
Conclusions. The presence of PVAT affects the HV of arteries, both in normal and in T2DM. The possibilities of ways of pharmacological modulation of the nitroxidergic system depending on the state of PVAT were determined.
DRM LISTS CREATED WITH CHATGPT: ANALYSING RECOGNITION MEMORY WITH CLIMATE-CHANGE THEMED LISTS
Authors: Şahin Gökhan
Published: July 2024

Machine learning and natural language processing have led to the development of powerful language models such as ChatGPT, which can generate consistent and human-like responses to a wide range of queries. In many domains, ChatGPT provides appropriate responses to given commands. One of the aims of this study is to investigate the use of these association lists, such as the Deese-Roediger-McDermott (DRM) lists popular in cognitive psychology studies, by ChatGPT by giving the necessary instructions. The same method was then used to create association lists around a specific topic (climate change). The results of the first study showed that participants gave more false answers when discriminating whether critical words were presented during the test phase than when related and unrelated words were presented. This finding shows that DRM lists generated by ChatGPT can be used to search for memory errors. In line with the literature, false answers for critical words were predominantly rated as ‘remember’. The results of the second study, which was applied to the lists created on the topic of climate change and compared the responses of the groups with the climate denial scores, show that there is no significant difference in the emergence of false memories between the two groups. The level of climate change denial did not significantly affect the participants’ responses to the critical words in the climate- related lists. The low level of climate denial in the sample is a limitation of this study. It is recommended that future studies compare memory performance across an appropriate sample.

Vaginatispora acrostichi sp. nov. was isolated from submerged stems of Acrostichum aureum (Pteridaceae) collected from the mangrove habitats of Pranburi District, Prachuap Khiri Khan, Thailand. Phylogenetic analyses based on the combined dataset of LSU, SSU, ITS, tef1-α, rpb2, and β-tub sequences placed the novel species within Vaginatispora. Vaginatispora acrostichi formed a well-supported sister clade with V. lignicola but differs from it morphologically and phylogenetically. Vaginatispora acrostichi is distinguishable from V. lignicola by ascospore size, septation and colour. The ascospores of V. acrostichi turn light brown at maturity and have a single septum with a minute constriction, while those of V. lignicola appear yellowish at maturity and have 1–3 septa with pronounced constriction. Vaginatispora acrostichi is introduced in this paper as a novel species with a comprehensive description and illustration.

Gambierdiscus is a marine benthic dinoflagellate genus that currently contains 19 species; some of them are toxigenic, producing ciguatoxins, maitotoxins, and other toxic compounds. The objective of this study was to document the morphological and molecular identification (ITS, 5.8S and 28S of the rDNA) of two strains of Gambierdiscus from La Gaviota Island, Gulf of California, Mexico, and a toxicity test. The shape of the 2′ plate varied between hatchet-shaped and rectangular, that complicated the differentiation between G. carpenteri and G. toxicus. Molecular markers of the three rDNA regions allowed confirmation of the taxonomic identity of G. carpenteri, separating this species from other congeners with high phylogenetic affinity, such as G. excentricus, G. toxicus and G. caribaeus. Studies of the morphological taxonomy of G. carpenteri are scarce; therefore, due to the similarity between species, the combination of morphological and molecular tools is recommended for the identification of species, such as G. carpenteri, G. excentricus, G. toxicus and G. caribaeus. The mouse bioassay showed that the examined isolate was toxic, and it is a potential etiology of ciguatera fish poisoning cases in the region. This study provides the first reliable report and ribosomal sequences of G. carpenteri for the Gulf of California, as well as data on mouse bioassay toxicity.
Deucravacitinib: moderate-to-severe plaque psoriasis preventable?
Authors: Kaur Manmeet , Misra Saurav
Published: July 2024

Psoriasis is a persistent, inflammatory, and autoimmune condition that is difficult to treat. Estimates of the prevalence of psoriasis in people range from 0.27 % (95 % confidence interval 0.17 to 0.36) to 11.4 %, depending on factors such as age, sex, geography, ethnicity, genetics, and environmental factors. While systemic treatments are typically required for patients with moderate-to-severe instances of psoriasis, topical therapies are frequently effective for treating minor forms. In fact, phototherapy is frequently constrained by logistical considerations, and conventional systemic therapies are frequently avoided due to contraindications or the danger of adverse outcomes. In order to better serve the patient and achieve a greater level of quality of life, especially in order to sustain long-term efficacy, there is still a need for innovative therapies, which are always welcomed. Deucravacitinib is a first-in-class oral tyrosine kinase 2 (TYK2) inhibitor that is extremely selective. Through an allosteric mechanism, it stabilises an inhibitory connection between the regulatory and catalytic domains of TYK2’s pseudokinase regulatory domain, which is catalytically inactive. This can be used to treat a variety of immune-mediated conditions, such as inflammatory bowel disease, lupus, psoriatic arthritis, and psoriasis. US-FDA has approved this drug on 9 September 2022 for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. This article aims to review the current knowledge on the efficacy and safety of deucravacitinib for the management of psoriasis.
Lawyer, Littérateur, and Legislator: On Gronemann’s Profession, Self-Perception and Place in Scholarship
Authors: Piotrkowski Meron M.
Published: July 2024

The essay explores the multifaceted career of Sammy Gronemann, emphasizing his overlooked role as a lawyer within the context of his better-known identities as a Zionist and a man of letters. Gronemann’s professional life, particularly his work as a lawyer and judge, is examined in detail, shedding light on his significant contributions to Zionist legal institutions such as the Court of Honor. The paper highlights the evolving trends in scholarly research on Gronemann, which primarily focuses on his literary achievements while neglecting his legal career. Through Gronemann’s own writings and historical documents, the paper delves into his self-perception, revealing a complex interplay between his identities as a lawyer and a writer. Ultimately, it argues that Gronemann’s passion and success spanned across his various roles, challenging conventional categorizations and underscoring the interconnectedness of his legal, literary, and Zionist endeavors.

The synthesis of zeolite nanoparticles is studied comprehensively by adding an organic template as a reflux method, extracted from crystals. The zeolite nano-crystals are quite effectively synthesized by incorporating silica, organic template, and alkali metal. The tetrapropylammoniumhydroxide, tetrapropylammoniumbromide and tetraethyl orthosilicate (TEOS) as organic templates are added for the assistance of zeolite (albite) crystals. A cross-linker TEOS is also mixed. Adding carbon nanotubes and graphene oxide made the morphology of albite more interesting. Nucleation time is an important feature for the formation of albite crystals. The albite nano-shaped crystal is developed for instance when reaction time is less than 240 h, after this period crystal size increases with time. Batch 1 of zeolite is prepared with additives for testing its morphology, like surface area, particle size shape, and crystal geometry. The general trend (e.g., pore volume, percentage composition, particle size, geometry) of zeolite nano-crystal is explained by the help of robust techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, energy-dispersive X-ray spectroscopy, and scanning electron microscopy.

In this study, sodium titanate (ST)/iron oxide (Fe2O3) was successfully prepared as a novel binary photocatalyst for the first time to enhance the photocatalytic activity. The prepared photocatalyst was used in the photodegradation of methylene blue (MB) dye under sunlight and a tungsten lamp. The green synthesis method using orange peel extract was employed to prepare Fe2O3, while the hydrothermal method was used to synthesize ST. To achieve optimal photocatalytic efficiency, the loading of Fe2O3 onto ST was carefully controlled. The average crystallite size of ST, Fe2O3, and ST@Fe2O3 (with a 1:1 wt% ratio) was 999.8, 81.9, and 104 nm, respectively, using the Williamson–Hall (W–H) model. Optical analysis revealed that ST@Fe2O3 had a smaller direct bandgap (2.54 eV) compared to ST@0.3 Fe2O3 (2.70 eV) and ST@0.5 Fe2O3 (3.24 eV). The photodegradation of MB was analyzed considering the weight of the photocatalyst, the irradiation time, and the dye concentration. In-depth explanations of stability and kinetic models were also provided. Remarkably, the ST@Fe2O3 photocatalyst demonstrated superior performance compared to the other evaluated photocatalysts, completely degrading MB dye within just 60 min of solar light exposure. Incorporating Fe2O3 into ST effectively reduces the recombination of photo-produced electron/hole (e/h) pairs and broadens the response range of the solar spectrum. Based on these findings, ST@Fe2O3 appears to have a promising future as a practical photocatalyst for degrading various dye pollutants in wastewater.

Published: July 2024

This study uses Multi-Island Genetic Algorithm (MIGA) and three-dimensional Computational Fluid Dynamics (CFD) software to optimize butterfly-shaped film cooling holes in the upper-stage rocket engine thrust chamber. The goal is to meet thermal protection and thrust requirements at high altitudes without re-ignition. To facilitate an all-encompassing worldwide search, the holes in the optimized design remain at set dimensions. Film continuity and stability at the nozzle outlet are greatly impacted by the hole structure. Inlet and divergence angles have little effect on thrust, according to regression research, but lip height (de) and outlet width (β) have a big impact on cold gas ejection, which affects cooling and thrust. Optimized results lead to a 20.49 K decrease in the monitoring section’s average wall temperature and a 52.8 N boost in thrust by reducing interference between supersonic airflow and extending film stability.

This essay provides a synthetic overview of the preceding articles in this special issue on Feminist Histories, situating them within the historical literature that helped shape the field of U.S. women’s history. Drawing out recurrent ideas across topics, the afterword identifies how the authors both build upon and innovatively expand the overlapping concepts of “the personal is political” and intersectional identities. They raise new questions about authorial experience, the inseparability of race, gender, and sexual politics, and the complexity of historical interpretation.
Vojna arhitektura Gospića na prijelazu iz 19. u 20. stoljeće
Authors: Došen Antonia
Published: July 2024

During the period of Vojna Krajina, a barracks complex was built in one of the main streets of Gospić, on Kaniška Street. It consisted of three buildings of barracks and three wooden structures. Alongside this complex, the commander’s apartment was also erected, also situated in Kaniška Street, and an officers’ mess hall located in the beginning of Budačka Street. Thanks to the analytical interpretation of the researched documentation of the new buildings in Domobranska Barracks in Gospić from the end of the 19th century, which is partly preserved in the Croatian State Archives in Zagreb, it is possible to reconstruct the course of construction of the main barracks building, changes within the barracks complex in the period preceding the First World War, as well as the changes in the barracs construction that were located in the community. This is the first study of Gospić military architecture from the transition period from the 19th to the 20th century.

Grafemsko-fonemski odnosi u tekstu Fojničke kronike (XVII. stoljeće)
Authors: Novaković Šimun
Published: July 2024

Rad se bavi grafemsko-fonemskim odnosima u Fojničkoj kronici s posebnim osvrtom na razlike i sličnosti prema tekstovima franjevačke spisateljske djelatnosti 17. i 18. stoljeća. Najprije se navode oni grafemi koji u Fojničkoj kronici uvijek označavaju isti fonem. Poseban naglasak stavlja se na prikaz pisanja nekih fonema koji se obilježavaju s dva grafema odnosno, u nekim slučajevima, pisanja istim grafemom nekoliko različitih fonema. Tako je vidljivo da se đervom označavaju fonemi /ć/ i /đ/ te da đerv u kombinaciji sa slovima l i n označava palatalne foneme /ļ/ i /ń/. Istim se grafemom obilježavaju fonemi /č/ i /ǯ/. Za obilježavanje fonema /k/ i /o/ upotrebljavaju se po dva grafema, s tim da postoje određena distribucijska pravila njihove uporabe. Glasovna skupina /št/ označava se jednim slovom. Uz vokalno /ŗ/ redovito se pojavljuje popratno slovo a, a fonem /j/ se označava grafemom za jat. Sve navedene osobitosti uspoređuju se sa stanjem kod nekih franjevačkih pisaca iz 17. i 18. stoljeća. Predmet interesa rada nisu samo pisci koji su objavljivali hrvatskom ćirilicom, nego i neki čija su djela objavljena latinicom jer je očit utjecaj latiničnih grafijskih pravila u označavanju nekih fonema u hrvatskoj ćirilici.

Introduction. Managing the lifelong learning environment requires a certain understanding of the educational needs and demands of learners of different categories. However, there is not The professional well-being of preschool teachers is sufficiently understudied, and operational models of professional well-being have not yet been built. The aim of the study is to develop a model of professional well-being of preschool teachers and to assess the quality of this model through empirical testing.
Materials and Methods. The study involved 818 teachers aged 19‒74 with work experience ranging from 3 months to 50 years. The data was collected with the Russian version of PERMA-Profiler (O. M. Isaeva, A. Yu. Akimova, E. N. Volkova, 2022), Questionnaire of Basic Needs in Work (E. N. Osin, D. D. Suchkov, T. O. Gordeeva, T. Yu. Ivanova, 2015), Questionnaire of Professional Motivation (E. N. Osin, et al., 2017), Utrecht Work Engagement Scale (D. A. Kutuzova, 2006), a short version of the Emotional Intelligence Questionnaire (A. A. Pankratova, D. S. Kornienko, D. V. Lyusin, 2022), and a short version of the Big Five (M. S. Egorova, O. V. Parshikova, 2016). The empirical data were collected online.
Results. The three-component composition of the model of preschool teachers’ professional well-being was identified with structural equation modeling. The model includes general well-being, activity and personal components. High professional well-being is associated with high level of basic PERMA characteristics, subjective feeling of good health; satisfaction of basic needs for autonomy, competence, relatedness; autonomous types of motivation; job satisfaction; the energy and efficiency of the teacher; high agreeableness, conscientiousness, openness to new experiences, extraversion and low neuroticism. The characteristics of a teacherʼs emotional intelligence were not included in the model.
Discussion and Conclusion. The presented study contributes to the understanding of the structure and components of professional well-being of preschool teachers. The model of professional well-being can be used by the management of preschool educational institutions to develop and implement individual professional development programs, as well as to address issues of teacher retention in the organization.

Autoimmune hepatitis – an increasingly common cause of hypertransaminasaemia among children. Case report and literature review
Authors: Szyller Hubert Paweł , Wrześniewska Martyna , Wołoszczak Julia , Braksator Joanna , Pytrus Tomasz
Published: July 2024

Autoimmune hepatitis is a chronic inflammatory process of unknown ethology, characterised by high levels of transaminases and IgG antibodies, the presence of tissue autoantibodies, and a typical histological picture. In the population of children, the paediatric form of autoimmune hepatitis and autoimmune sclerosing cholangitis are collectively classified as juvenile autoimmune liver disease. The condition often coexists with other autoimmune disorders. This paper aims to present the clinical profile of a paediatric patient with full-blown autoimmune hepatitis and describe the available therapies. The patient, a 13-year-old boy, was referred to a specialised hospital because of increasing hypertransaminasaemia. The patient was hospitalised for the first time at a district hospital for abdominal pain, and during his stay, elevated transaminases were found with a tendency to increase in follow-up tests. The picture suggested an inflammatory process of the liver and biliary tract. Upper gastrointestinal endoscopy revealed lesions consistent with chronic gastritis and portal gastropathy. Treatment included thiazolidinedioic acid, vitamin K, ursodeoxycholic acid, rifaximin, ciprofloxacin, and proton pump inhibitors. Therapy is aimed at maintaining immunosuppression and inhibiting the inflammatory response that leads to cirrhosis, and most commonly uses steroids alongside proton pump inhibitors for added protection or, alternatively, mycophenolate mofetil, cyclosporine A, tacrolimus, and biologic therapy. Ursodeoxycholic acid also exhibits immunomodulatory properties and makes it possible to reduce steroid doses and thus decrease the likelihood of adverse effects of therapy.

The study is devoted to the functioning of the Polish language in the village of Vershina, Irkutsk region of the Russian Federation. This village, one of the few places in Russia where, in addition to the Russian language, the Polish language is widely used in everyday life, is due to the fact that the majority of the population of the village are ethnic Poles who settled here at the beginning of the 20 th century. As part of the research work, the following tasks were set: 1. Identify the type of migration process that resulted in the emergence of this enclave. 2. Make a linguistic description of the dialect. 3. To reveal the regularities of the interaction of the Polish language with the Russian idiom, in the environment of which it functions.

Published: July 2024

The study's object is the process of extracting the characteristics of lambda terms, which indicate the optimality of the reduction strategy and increase the productivity of compilers and interpreters. The solution to the problem of extracting specific strategy priority data from lambda terms using Machine Learning methods was considered.
Such data was extracted using the large language model Microsoft CodeBERT, which was trained to solve the problem of summarizing the software code. The resulting matrices of embeddings were used to obtain vectors of average embeddings of size 768 and a latent space of size 8 thousand. Further, vectors of average embeddings were used for cluster analysis using the DBSCAN and Hierarchical Agglomerative clustering methods. The most informative variables affecting clustering were determined. Next, the clustering results were compared with the priorities of reduction strategies, which showed the impossibility of separating terms with RI priority. A feature of the obtained results is using machine learning methods to obtain knowledge.
The clustering results showed many of the same informative variables, which is explained by the similar shape of the obtained clusters. The results of comparing the clustering values with the real priority are explained by the impossibility of clearly determining the priority and the use of the Microsoft CodeBERT model, which was not trained for the analysis of lambda terms.
The proposed approach can find application in the development of compilers and interpreters of functional programming languages, allowing to analyze the code and extract important data to optimize the execution of programs.

The object of this study is the screen-exhaust device in the TV3-117 engine of the Mi-8MSB-B helicopter.
To reduce visibility in the thermal range, a system of mixing hot engine exhaust gases with ambient air is used; this technique makes it possible to reduce the infrared radiation of engines. For this purpose, a new sample of screen-exhaust device was designed for testing.
A thermal imaging survey of the helicopter was conducted. Three variants of thermal images were acquired: a helicopter without installation of a thermal visibility reduction system, a helicopter with standard exhaust shields installed, and a helicopter with newly developed shield exhaust devices installed. Based on the obtained experimental results, the characteristics of the intensity of infrared radiation were determined for three variants of research in the range of thermal waves of 3–5 μm. The study uses a comprehensive approach to solving the tasks, which includes a statistical analysis of known and promising ways to protect a helicopter from guided missiles with infrared homing heads based on reduced radiation forces and a theoretical method for calculating flow and temperature fields. The advantages of placing the section of the exhaust channel of the designed screen-exhaust device in the horizontal plane for complete shielding of infrared radiation in the lower hemisphere have been experimentally proven. The benefits of directing the flow of exhaust gases from the screen-exhaust device into the space above the helicopter propeller and dividing this flow into four separate flows were shown. The results of experimental research could be used to design new or improve existing screen-exhaust devices by the developers of military aviation

The object of this study is the processes of occurrence, perception, and redistribution of loads in the body of a gondola car with reinforcing belts in the structure of side walls.
In order to improve the strength of side walls of the gondola car body, it is proposed to strengthen them with additional belts. At the same time, it is reinforced with diagonal belts in three sections of the body on the side of the consoles, and in the middle section, 1/3 of the height from the lower strapping, with a horizontal belt. To determine the parameters for the execution of profiles in the reinforcing belts, the calculation of the gondola car body as a rod system was carried out. Based on the resulting values of bending moments, the moment of resistance of the cross-section of the profiles of the reinforcing belts was determined. The calculation of the strength of the body of the gondola car under the main modes of its loads in operation (I and III calculation modes) was carried out. It was found that the resulting stresses were 10.3 % lower than those occurring in a typical design of a gondola car body. The movement of the gondola car in the empty and loaded states was evaluated.
A feature of the reported research results is that the improvement of the strength of the side walls of the gondola car body is achieved by increasing the rigidity of its frame.
The field of practical use of the results is the engineering industry, in particular, railroad transport. The conditions for the practical application of results are the symmetrical distribution of reinforcing belts along the length of the gondola car body.
This study results may contribute to improving the durability of gondola car bodies in operation, and accordingly to reducing costs for unscheduled repairs. Also, the findings could prove useful for designing modern structures of railroad cars

The object of this study is the pneumatic system in the spring suspension of rolling stock under conditions of high-speed movement from 170 to 250 km/h.
Based on the thermodynamic model of the pneumatic spring suspension system, the influence of volume of the additional tank and the initial pressure in the pneumatic spring on the nature of change in the spring's dynamic stiffness, energy losses, and damping coefficient was studied.
Based on the built "force-deformation" dependences for the pneumatic spring, it was established that the change in the volume of an additional tank has a slight effect on the deformation of the pneumatic spring at different speeds of the high-speed rolling stock.
It was established that in the range of rolling stock speeds of 170–250 km/h, the diameter of the connecting pipeline is 30 mm, and the volume of the additional tank is from 30 to 60 l, the maximum change in the dynamic stiffness of the pneumatic spring up to 15.5 % occurs at the pressure in the spring of 6.5 bar.
Dependences of energy loss and damping coefficient during the operating cycle of the pneumatic spring suspension system were derived. It was established that an increase in the volume of the additional tank and the initial pressure in the pneumatic spring leads to an increase in the energy loss during the operation cycle of the pneumatic system. The maximum values of the damping coefficient over the entire considered range of variable parameters are 1.16–1.29.
It was established that with the volume of the additional tank in the range from 30 to 50 liters, the maximum values of the damping coefficient are observed at a diameter of the connecting pipeline of 25 mm and a speed of movement from 200 to 250 km/h. And with an additional tank volume of 60 liters – with a diameter of 30 mm and a speed of 170 to 250 km/h

The object of the study is to determine the critical impact speed during shell destruction, study crack formation in the shell, and grind the shell. When operating a grinder-mixer-dryer, problems arise such as determining the speed of impact on the shell depending on the height of its fall, the lack of ability to determine the speed of shell fall from certain heights, which complicates planning the operation of the finger shaft. As a result of research, it was found that an auger with knives crushes and moves feed raw materials, and the impact-spreading shaft ensures partial grinding of fragile raw materials and intensive processes of mixing and drying wet feed with uniform filling of the installation hopper. The appearance of cracks on the shell when it falls from a height of 0.15 m has been experimentally recorded. Therefore, this speed of impact of the shell on a metal surface is the critical peripheral speed of the impact-spreading shaft, which ensures partial crushing of the shell. As a result of theoretical studies, an analytical expression was obtained that provides the determination of the shell impact speed depending on the height of its fall. The value of the critical peripheral speed of the fingers of the impact-spreading shaft is determined to be 1.66 m/s. The experimental results showed the effective occurrence of grinding, mixing and drying processes. Moreover, within 15 minutes of operation of the installation, the wet shell was crushed in accordance with the requirements. The uniformity reached up to 90 % within 4 to 6 minutes of its operation, and drying proceeded at a rate of 26.54 % per hour. All this proves the effectiveness of the processes of grinding, mixing and drying wet food, and also confirms the reliability of theoretical research

The object of the study is the process of changing tribological efficiency according to tribotechnical characteristics (wear intensity, friction coefficient, temperature in the contact zone) of composites based on phenylone C-1 and polyamide PA-6 with arimide-T filler and fullerene C-60. The study solved the problem of obtaining composites with high wear resistance.
Based on the results of research, it was found that varying the content of arimide-T makes it possible to obtain composites with different patterns of changes in tribotechnical characteristics under conditions of dry friction, lubrication with water and I-50 oil. Composites with the composition: phenylone C-1+15 wt. have the maximum tribological efficiency. % arimide-T+3 wt. % fullerene C-60 and polyamide PA-6+30 wt. % arimide-T+3 wt. % fullerene C-60.
Phenylone C-1 has destructive properties when working in the environment of water and temperature in the friction zone. Its reinforcement with arimide-T and fullerene C60 gave positive results of a complex of tribotechnical characteristics under these conditions. It was found that the wear of composites based on phenylone C-1 in I-50 oil is two orders of magnitude lower than in water. Research of samples from the obtained composites based on phenylone C-1 and polyamide PA-6, reinforced with the optimal content of arimide-T and fullerene C60, showed that their wear resistance when lubricated with oil is 3.5...4.0 times greater than the wear resistance of bronze.
An applied aspect of the reported results is the introduction of manufacturing technologies and restoration of machine parts from the proposed composites. It has been proven that their optimal composition contributes to high tribological efficiency and could provide the required level of wear resistance and reliability of resource-determining nodes, systems, and machine assemblies.
The results could be used by machine-building and repair-technological enterprises
