Stechoq Robotika Indonesia] Today problems in the industrial world are increasingly complex and dynamic, including the matter of supplier selection. Supplier selection has a significant effect on the success of logistics and supply chain management. PT. Stechoq Robotika Indonesia is an R&D and manufacturing company in D.I. Yogyakarta produces Genose, Ventilator, DCS, and others. Bolt components are one of the components that are always used and their availability must be ensured through supplier assessment. This research was conducted to determine which bolt supplier is the best based on predetermined criteria and sub-criteria. Variables include price, quality, delivery, quantity accuracy, and service. To determine the preference order of bolt suppliers, this study uses AHP which assigns individual probability scores for each criterion, and TOPSIS, which gives users an indication of which supplier to choose when selecting bolts. As a result of data processing, suppliers are ranked based on their preferences. The preference value for each supplier is: supplier 1, equal to 0.6295; supplier 2 of 0.5648; supplier 3 of 0.6288; supplier 4 of 0.3156; supplier 5 is 0.4445, supplier 6 is 0.5343; and supplier 7 of 1.0000. Of the five parameters used in this research, quality has to have the most influence at 35.5%.Keywords: AHP; Supplier Selection; TOPSIS
A diagnostic method for cardiomyopathy based on multimodal data
Authors: Shen Linshan , Zhang Xuwei , Huang Shaobin , Wu Bing , Li Jingjie
Published: April 2023

Objectives

Currently, a multitude of machine learning techniques are available for the diagnosis of hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) by utilizing electrocardiography (ECG) data. However, these methods rely on digital versions of ECG data, while in practice, numerous ECG data still exist in paper form. As a result, the accuracy of the existing machine learning diagnostic models is suboptimal in practical scenarios. In order to enhance the accuracy of machine learning models for diagnosing cardiomyopathy, we propose a multimodal machine learning model capable of diagnosing both HCM and DCM.

Methods

Our study employed an artificial neural network (ANN) for feature extraction from both the echocardiogram report form and biochemical examination data. Furthermore, a convolutional neural network (CNN) was utilized for feature extraction from the electrocardiogram (ECG). The resulting extracted features were subsequently integrated and inputted into a multilayer perceptron (MLP) for diagnostic classification.

Results

Our multimodal fusion model achieved a precision of 89.87%, recall of 91.20%, F1 score of 89.13%, and precision of 89.72%.

Conclusions

Compared to existing machine learning models, our proposed multimodal fusion model has achieved superior results in various performance metrics. We believe that our method is effective.
New Wine in Old Wineskins? Incomplete Democratization in Brazil During the First Pink Tide
Authors: Sobottka Emil A.
Published: April 2023

During the last decades in Brazil, two societal projects strived for hegemony: a democratic and participatory project disputed against an alliance of the emerging bourgeoisie with traditional political forces. The PT-led government, driven by Lula da Silva (2003–2010) and Dilma Rousseff (2011–2016), representative of the democratic and participatory line, implemented many innovative policies concerning notably social citizenship rights and industrialization. Perhaps, like many other Latin American countries during the first pink tide, it was unsuccessful in transforming the old economic, political, and social frameworks to provide a suitable environment for new politics. The text examines this period, emphasizing improvements in political participation, inclusive social policies, and the relationship between the government and social movements, as well as some flaws that hastened its demise.
Characterization of wear and fatigue behavior of aluminum piston alloy using alumina nanoparticles
Authors: Alshalal Iqbal , Al-Zuhairi Haitham M. Ibrahim , Abtan Auday Awad , Rasheed Mohammed , Asmail Muna Khalil
Published: April 2023

Due to their excellent thermal conductivity, lightweight, and ease of processing, aluminum alloys are the material of choice for piston manufacture in internal combustion engines. Nanoparticles (NPs) of alumina (Al2O3) with a size of 25 nm were incorporated into an aluminum piston alloy to examine the effect of the NP addition on wear resistance and fatigue behavior. The stir casting method has been utilized to manufacture experimental samples of the composite material by altering the particle weight ratio of aluminum to the matrix alloy to 2, 4, and 6 wt%. The surface morphology of the samples has been examined using an electronic scanning microscope. The results of the wear and fatigue tests indicate that the addition of Al2O3 to the composite enhanced its fatigue resistance and wear strength, with the exception of 6 wt% weight ratio. The best improvement in wear resistance and fatigue strength occurs at 4 wt% Al2O3 particles, which are 12.13 and 67.5%, respectively, more significant than the pure metal and other composites. The mechanical properties of the alloy samples have been enhanced by adding Al2O3 NPs of 25 nm size into the piston’s aluminum matrix alloy. Stir casting was employed to produce the needed composites by incorporating Al2O3 NPs at varied weight percentage ratios of 0, 2, 4, and 6 wt% into the master alloy. Before the composite alloy reached 6 wt%, including Al2O3 NPs, the alloy’s hardness and tensile strength improved, according to the experiment results.

Published: April 2023

In this article, the bond performance between recycled concrete and corroded steel bars is analyzed by the nonlinear numerical simulation. The result shows that the maximum bond strength between recycled concrete and steel bar decreases with the increase in steel bar corrosion rate; when the recycled concrete strength is large, the simulated maximum bond strength is in good agreement with the experimental maximum bond strength; when the recycled concrete strength is small, the simulated maximum bond strength is in relatively poor agreement with the experimental maximum bond strength, but there is still an error within the allowable range; the slip between recycled concrete and steel bar increases with the increase in steel bar corrosion rate; when the steel bar corrosion rate exceeded 5%, the bond strength decreases more rapidly; the maximum bond strength increases with the increase in specimen sizes under the same steel bar corrosion rate; the maximum bond strength decreases with the increase in steel bar diameter under the same steel bar corrosion rate.
Archaeology of Radiant Mediations
Authors: Smolicki Jacek
Published: April 2023

This essay explores cultural, environmental, material, and political testimonies of the Gleiwitz radio tower constructed in the 1930s near the border of Germany and Poland (today Gliwice). As the tallest wooden structure of its kind in Europe, the mast has over the last century witnessed several turbulent geopolitical transitions. Those, in turn, have systematically redressed its functions to serve various, often radically competing intentions: from spreading Nazi propaganda before and during World War II to jamming frequencies of West European radio stations during the communist era. Recently, the site has become subject to conspiracy theories related to 5G infrastructure allegedly installed on the mast’s no-longer-functional structure. Attending to the concept of pharmakon that pertains to inherently mixed properties of a medium, this essay traverses these diverse historical trajectories and explores a disparate range of reverberations, events, and effects that this radio mast and its unique material affordances have over time instigated not only across human but also other-than-human realms, scales, and temporalities. Understanding media as mediations, while drawing on the case of the Gleiwitz radio mast, I take an approach in which radio becomes an instance of radiant mediation and hence radiation. This move enables us to see radio as an event that is always-already implicated in and informed by a specific climate and its transformations: environmental, social, and geopolitical, to name but a few. Consequently, the article puts forth a reading of pharmakon as a highly relational and unstable phenomenon, never an intrinsic feature of a given medium or media infrastructure. Traversing the complex history of the Gleiwitz radio mast, the essay brings to the fore key moments during which this relational reading of pharmakon of interest here becomes particularly illuminated.

Analisis Perbandingan Asas Teritorialitas dan Asas Non-Teritorialitas dalam Pemikiran Hukum Islam
Authors: Darmalaksana Wahyudin
Published: April 2023

Penelitian ini bertujuan menganalisis padangan teritorialitas Abu Hanifah dan non-teritorialitas Imam Syafi’i. Penelitian ini menggunakan pendekatan kualitatif dengan metode analitis hukum Islam. Hasil penelitian dan pembahasan menunjukkan bahwa asas teritorialitas Imam Abu Hanifah menegaskan bahwa seorang muslim pasti terikat untuk melaksanakan hukum Islam sepanjang orang tersebut berada di wilayah hukum di tempat syariat diberlakukan, sedangkan teori non-teritorialitas Imam al-Syafi’i menuturkan bahwa seorang muslim pasti selamanya terus terikat untuk pelaksanaan syariat di mana pun orang tersebut berada, baik pada wilayah hukum di mana syariat diberlakukan maupun pada wilayah hukum di mana syariat tidak diberlakukan. Penelitian ini menyimpulkan bahwa perbedaan pendapat antara Abu Hanifah dan Imam al-Syafi’i terkait hubungan internasional dalam bidang hukum Islam terletak pada asas di mana pendiri mazhab Hanafi menekankan asas teritorialitas dan pelopor mazhab Syafi’i menegaskan asas internationalitas.TRANSLATE with x EnglishArabicHebrewPolishBulgarianHindiPortugueseCatalanHmong DawRomanianChinese SimplifiedHungarianRussianChinese TraditionalIndonesianSlovakCzechItalianSlovenianDanishJapaneseSpanishDutchKlingonSwedishEnglishKoreanThaiEstonianLatvianTurkishFinnishLithuanianUkrainianFrenchMalayUrduGermanMalteseVietnameseGreekNorwegianWelshHaitian CreolePersian //  TRANSLATE with COPY THE URL BELOW Back EMBED THE SNIPPET BELOW IN YOUR SITE Enable collaborative features and customize widget: Bing Webmaster PortalBack//
Japan’s Science and Technology Diplomacy: Society 5.0 and its International Projection
Authors: López-Aranguren Juan-Luis
Published: April 2023

Japan is the third largest economy on the planet but lacks coercive capacity due to Article 9 of its Constitution, which prevents it from having an army and declaring war. This means that it can only rely on persuasion to influence the international sphere and achieve its political objectives. One of the tools it has for this purpose is public diplomacy, which is diplomacy exercised through non-traditional means such as communication, art and culture. One branch of public diplomacy is science and technology diplomacy (S&T Diplomacy), which consists of collaboration in these areas with other nations to strengthen their international projection, as well as the dissemination of scientific knowledge and technology transfer between nations. S&T diplomacy has become a major focus for Japan of its diplomatic action since it launched the Society 5.0 project in 2016, which sought to revolutionize Japan’s economy, society and governance through technology. This S&T diplomacy has the potential to not only strengthen Japan’s external action, but also to transform its industries and research while it is transforming the infrastructures of Japan’s partner nations, like the construction of subway and high-speed rail networks in India. This article will first analyze the theoretical framework of public diplomacy and science and technology diplomacy. Next, Japan’s public diplomacy will be studied by comparing The Soft Power 30 and Global Soft Power Index. Finally, Japanese science and technology diplomacy will be analyzed by assessing the initiatives contained in the Japanese Society 5.0 project.
Instagram as a participatory tool: A comparative analysis of six Spanish museums
Authors: Kaiser-Moro Andrea , Sánchez-Mesa-Martínez Domingo
Published: April 2023

Digital media is usually understood as a tool that helps the social and participatory ideal of museums and cultural institutions to materialize. This ideal has its roots in the reflections that, since the 1980s, new museology and critical museology movements have developed around the renewal of cultural organizations: a transformation that places the visitor at the center of the institution, revises their stories about its collections and invites institutions to be more participative with the public. Seeking to identify the characteristics that these theories adopt in practice, this article investigates the forms of participation implemented on Instagram by six Spanish cultural institutions: Museo Nacional del Prado Museum, Museo Nacional Thyssen-Bornemisza, Museo Nacional Reina Sofía, Museo Guggenheim Bilbao, Museo de Arte Contemporáneo de Barcelona (MACBA) and Centro de Cultura Contemporánea de Barcelona (CCCB). By way of a content analysis of their publications over the span of 6 months, patterns and trends have been identified within the communication strategies of these organizations. The results indicate a clear predominance of minimalist participatory forms (those oriented towards access to practical information and the discovery of collections) over maximalist modalities related to collaboration or co-creation. In general terms, there is also a considerable presence of audiovisual formats in the publications analyzed, showing the great capacity of these institutions to adapt to the latest changes in Instagram.
Historiografía sobre el Concilio de Nicea: el Concilio de Nicea a la luz de sus historiadores
Authors: Alba-López Almudena
Published: April 2023

La importancia y trascendencia del primer concilio ecuménico ha sido objeto de reflexión desde su propio tiempo. Eusebio de Cesarea y los diferentes historiadores eclesiásticos de los siglos iv y v no tardaron en glosar el desarrollo del sínodo vinculando, inseparablemente, la consustancialidad de Padre e Hijo enunciada en Nicea a la ortodoxia cristiana determinando y, en cierta medida, condicionando la posterior reflexión sobre el concilio y su influencia histórica y teológica. En la presente contribución abordaremos el desarrollo de la reflexión historiográfica y teológica en torno al concilio de Nicea por sus inmediatos contemporáneos, así como su influencia en las últimas décadas, centrando nuestra atención en el análisis efectuado en las principales monografías y estudios consagrados al estudio de su naturaleza y trascendencia.

Authors: Jaremen Daria , Michalska-Dudek Izabela
Published: April 2023

Głównym celem artykułu była identyfikacja zmian w procesie podejmowania decyzji zakupu przez nabywców pakietów wakacyjnych pod wpływem pandemii wirusa COVID-19. Do jego osiągnięcia przeprowadzono kwerendę literatury naukowej, a także badania nabywców usług turystycznych (N =1502) dotyczące problematyki realizowania podróży przed pandemią oraz w czasie jej trwania. Dane zostały zgromadzone techniką sondażu pośredniego, tj. Computer Assited Web Interview (CAWI), a do ich analizy posłużyły metody statystyki opisowej. Uzyskane wyniki pozwoliły na pozyskanie nowej wiedzy na temat wzorców zachowań nabywców spakietyzowanych podróży turystycznych oraz wyróżnienie czterech segmentów rynku imprez turystycznych. Najliczniej reprezentowane w badaniu kategorie zachowań nabywców (łącznie blisko 95% przed pandemią i nieco ponad 92% wskazań w jej trakcie) potwierdzają rolę Internetu w procesach dokonywania zakupów przez klientów biur podróży oraz tendencję postępującej wirtualizacji zachowań nabywców na rynku turystycznym. W trakcie trwania pandemii COVID-19 w przypadku zakupu zorganizowanych imprez turystycznych zaobserwowano, iż zdecydowanie rzadziej niż przed jej wystąpieniem nabywcy zorganizowanych pakietów przenoszą do sieci cały proces zakupowy, a więc zarówno poszukują informacji na temat ofert biur podróży, jak i dokonują zakupów w Internecie.
Młodzi konsumenci w społeczeństwie konsumpcyjnym – wnioski z badań
Authors: Kamińska Monika , Krakowiak-Drzewiecka Monika
Published: April 2023

Głównym celem badania było rozpoznanie zachowań młodych konsumentów w kontekście współczesnych trendów w konsumpcji. Owe trendy zmierzają w dwóch przeciwstawnych kierunkach – konsumpcji nadmiernej i niezrównoważonej oraz świadomej i zrównoważonej. Wybór młodych konsumentów jako podmiotu badania wynikał z tego, że są oni bardziej wrażliwi na nowe trendy niż starsi konsumenci i szybciej przejmują zachowania konsumenckie od innych. Badanie miało charakter eksploracyjny i składało się z dwóch etapów. Pierwszy obejmował badanie wtórne, które posłużyło do przygotowania i przeprowadzenia badania bezpośredniego wśród wybranych studentów Uniwersytetu Ekonomicznego w Katowicach. W badaniu wykorzystano metodę ankiety online. Informacje zgromadzone w toku badania wtórnego i pierwotnego pozwoliły na sformułowanie wniosku, że zachowania młodych konsumentów świadczą o zyskiwaniu na popularności konsumpcji świadomiej i zrównoważonej, choć trudno mówić o jej dominacji nad konsumpcją nadmierną.

ABSTRACT BACKGROUND: Although bariatric surgery is today’s gold standard treatment for obesity, weight regain affects the success rate of the procedure. Recent studies have identified psychiatric and neurological factors as possible causes. AIMS: The aim of this study was to evaluate the influence of psychiatric diseases on the outcome and long-term success of bariatric surgeries and find a weight regain threshold that has an acceptable sensibility to mental health-related issues to be used in research and clinical studies. METHODS: This is a observational study of bariatric patients submitted to Roux-en-Y bypass or sleeve gastrectomy, with a postoperative time of 2–10 years to access weight regain, depression, and binge-eating disorder. RESULTS: Of 217 patients studied, 163 were women and 54 were men, with an average postoperative time of 5.2±2.6 years. Weight regain was experienced in 35% of the patients, binge-eating disorder in 24.9%, and depression in 24%. The greater weight before surgery, body mass index (BMI), percentage increase to maximum weight loss, and time postoperatively all have a significant positive correlation with weight regain (p=0.045, p=0.026, p<0.001, and p<0.001, respectively). A significant association between binge-eating disorder, depression, and anxiety with weight regain (p=0.004, p=0.008, and p=0.001, respectively) was found. CONCLUSIONS: The significant weight regain rates with significant impact on psychiatric disorders highlight the need for continuous postoperative monitoring focused on the psychiatric aspects of obesity to aid surgeries’ long-term success.
Fly-ash-based geopolymer modified by metakaolin for greener grouting material
Authors: Li Feng , Yang Zhanning , Zhou Siqi , Zhang Xiao , Liu Duanyang , Su Yijie , Niu Qi
Published: April 2023

Fly ash usually requires high-temperature maintenance owing to its low volcanic ash activity, which greatly limits its application. In this study, fly-ash-based geopolymer grouting materials were prepared by modifying them with suitable alkali activators and metakaolin at room temperature. The results of the orthogonal experiments showed that the content of metakaolin had the most significant effect on the 1-, 7- and 28-day mechanical properties of the material. The optimum mix proportion was determined as metakaolin content (m MK/m P) = 15%, sodium silicate modulus (M s) = 1.0 and sodium silicate content (m SS/m P) = 50%. The compressive strengths of the materials at 1, 7 and 28 days were 12.6, 24.9 and 36.3 MPa, respectively. The results of X-ray diffraction, Fourier transform infrared spectroscopy, mercury intrusion porosimetry and scanning electron microscopy showed that the reaction mechanism of fly ash was subject to a bidirectional alkaline attack. Meanwhile, the unreacted fly ash particles proved the inertness of fly ash, while metakaolin mostly dissolved and formed hydrated sodium aluminosilicate gel to increase the mechanical strength of the geopolymer. The material developed in this study can meet the specification requirements of inorganic cementitious material for road grouting in terms of compressive strength and fluidity, increasing the usage of fly ash and contributing to environmental protection.
In Search of Dominant Drivers of the Real Exchange Rate
Authors: Oh Hyunseung , Miyamoto Wataru , Nguyen Thuy Lan
Published: April 2023

We uncover the major drivers of macro aggregates and the real exchange rate at business cycle frequencies in Group of Seven countries. The estimated main drivers of key macro variables resemble each other and account for a modest fraction of the real exchange rate variances. Dominant drivers of the real exchange rate are orthogonal to main drivers of business cycles, generate a significant deviation of the uncovered interest parity condition, and lead to small movements in net exports. We use these facts to evaluate international business cycle models accounting for the dynamics of both macro aggregates and the real exchange rate.

Motorcycles are the top contributor in road crashes in Malaysia with more than 60% of fatal road crashes involved motorcyclists. Conspicuity issue has been one of the major factors of motorcycle crashes especially when travelling at night in rural road areas. Nevertheless, conspicuity issues also contribute to motorcycle crashes in urban road areas where road and vehicle lightings affect the alertness of other road users towards motorcycle presence in the traffic. This study aims to assess road users’ perception of motorcycle safety levels in terms of its conspicuity, at different riding or driving situations at night in the rural and urban areas. A set of questionnaires was developed with experts’ validation, pilot-tested for its reliability and distributed to road users who commute between Klang Valley and Melaka areas. Preliminary analysis from 78 collected data shows that respondents were able to observe better and be more alert of motorcycle presence in road situations when driving in the urban areas compared to the rural areas. Over 80% believe that wearing bright-coloured attires and helmet can enhance motorcycle’s conspicuity and alertness towards other road users. In addition, more than 80% of the respondents agreed that using reflective tapes on the side body of a motorcycle can improve motorcycle visibility, especially at road junctions. These findings could be used as a future initiative by responsible parties in order to reduce motorcycle conspicuity related crashes in Malaysia.

Background. Subdural empyemas are accumulation of pus between the dura mater and the arachnoid mater of the brain. They represent 12–25 % of all intracranial purulent‑inflammatory diseases. 70–80 % of them are located convexitaly and 10–20 % in the area of the falx cerebri. A spread of pus on the tentorium cerebellum occurs rare. Without timely treatment, that includes massive therapy with antibiotics and drainage of the subdural empyema, most of the patients die in the result of progression of the secondary purulent meningoencephalitis and dislocation of the brain.

Аim. To report the case of subdural empyema of rare localization – in the left part of the interhemispheric fissure and supratentorial space, to demonstrate the effectiveness of prolonged continuous flow drainage in treatment of the subdural empyema in this particular case.

Materials and methods. 16‑year‑old patient was admitted into the neurosurgical department of the 1‑st Republican clinical hospital of the Izhevsk city with pronounced general infectious and meningeal syndrome and paresis of the muscles of his right shin and foot. CT scans revealed frontal sinusitis and subdural empyema of the left part of the interhemispheric fissure and the supratentorial space. In addition to intravenous antibacterial therapy with vancomicyn and Meronem bifrontal cranioectomy, debridement of the frontal sinus, obliteration of it’s residual cavity with free muscle graft and external drainage of the subdural empyema with following continuous irrigation during 6 days after surgery had been performed. At the time of discharge from the neurosurgical department 16 days after the operation complete regress of the general infectious and meningeal syndrome was observed.

Results. On control examination 44 days after the surgery the patient’s condition was normal and he had no neurolog ical deficit. On the series of MRI scans preformed 6 months latter, after the cranioplasty, no remnants of the subdural empyema were revealed.

Conclusions. This clinical case demonstrates the effectiveness of the prolonged continuous flow drainage in combination with systemic antobioticotherapy and elimination of the primary source of infection within the frontal sinus in treatment of the large and deeply situated subdural empyema of rare falcotentorial localization.

The article defines the concept of “Internet meme”, analyzes its main characteristics, defines the main types, describes the methodology of content analysis of memes. The purpose of this study is to carry out a computer content analysis of memes, to identify their features, and to determine their functions. Researchers analyzed 240 Internet memes about the Russian-Ukrainian war in 2022. Ukrainian social networks were used as the source of memes, the sampling period: from February to October 2022. The sample included memes of the content-image type with a verbal component (creolized memes) or without it (graphic memes). Content analysis was carried out using MAXQDA software. The system of categories (codes) – formal and content – was developed. The formal categories of memes include the following: meme type, meme language, communication levels, topic. The content codes include vocabulary with such subcodes, as standard vocabulary, substandard vocabulary. The analysis of memes with the help of formal categories showed that the most often occurred memes used in social networks are memes on military topic, which contain a verbal component in Ukrainian on the level of communication or some captions or inserts. The analysis of memes about the Russian-Ukrainian war on the lexical level showed that almost half of them contain substandard elements, among which ethnic slurs and obscenities dominate. Euphemisms and neologisms often create a satirical effect. The article also defines the following functions of memes: entertaining, anti-stress, expressive, pragmatic, ethnic, identification, epistemological, of collective involvement. Verbal and visual components of creolized memes do not compete, but complement each other. The perspective of this study is the analysis of humorous techniques in verbal memes.

BACKGROUND: Engine and vehicle control systems must have means of objective control in the form of self-diagnosis. This is especially true for new designs and technologies for controlling a gasoline internal combustion engine, such as deactivating cylinders in partial load mode. The paper gives an assessment of the possibility of self-diagnosis of cylinder shutdown in an automobile crank-guide engine without connecting rods using artificial neural networks.
AIMS: Determination of the possibility of creating an artificial neural network that recognizes which cylinders are currently in operation and which are disabled, based on the nature of the change in the signals from the sensors installed on the engine mounts and independent on the crankshaft speed.
METHODS: The study considered artificial neural networks of the LSTM and BiLSTM topology. An engine simulation model made in Simulink was used in order to obtain sensor signals. The conducted numerical experiments made it possible to obtain data, which simulates the sensors readings, and to train artificial neural networks to determine the order numbers and quantity of deactivated cylinders. Numerical experiments were carried out on the basis of full-factorial design. Various designs of experiments were used for training and testing of artificial neural networks, which made it possible to test the network on data that differed from the training data significantly. Testing took place on a large number of random sequences of cylinder deactivation modes.
RESULTS: The obtained results show a high degree of recognition of the order numbers of deactivated cylinders just after several tens of degrees of the crankshaft rotation while switching to the corresponding mode. For the LSTM network, mode detection accuracy was above 99% in both the data sequence transfer mode and the data streaming mode. Accuracy of the BiLSTM topology was over 99.9% in the data sequence transfer mode, but significantly decreased in the data streaming mode.
CONCLUSIONS: The use of considered types of networks in engine and car control systems is promising.

Published: April 2023

BACKGROUND: The steppe regions of the North Caucasus, the Volga region and the Central Chernozem regions of insufficient and unstable humidification are exposed to strong winds, which destroy and blow out the soil, cause dust storms, damage crops and often destroy them over large areas. It was found that the main foci of dust storms were areas plowed by ordinary dump tools. In this regard, the non-fall (flat-cut) tillage widely used in Northern Kazakhstan and Western Siberia with the preservation of most of the crop residues on the soil surface has acquired great importance. At the same time, tillage with chisel cultivators or plows, as well as rippers-slits with pointed loosening paws, allows to reduce the total energy consumption by 1.3-1.5 times, and also improves the agrophysical properties of the soil and increases crop yields.
AIM: The present study deals with a development of soil-free soil protection technology that contributes to the accumulation of moisture and increase yield.
METHODS: The method includes non-tillage tillage together with the cutting of cracks and the formation of cavities. The device consists of a hinged frame with support wheels and working bodies. The non-shaft working bodies are installed in a staggered order and contain C-shaped racks with chisels fixed at the end and flat-cut trapezoidal semi-paws on the sides. Drainers are fixed behind the racks, trapezoidal semi-paws in the front part are fixed pivotally on axes rigidly fixed on the sides of the rack, and in the rear part they have a kinematic connection with the mechanism of the swinging washer, connected, in turn, with the power take-off shaft of the power means.
RESULTS: The working process of the method of accumulation of moisture in the soil is carried out as follows: after harvesting the previous crop, peeling is performed, and then furrows are cut with simultaneous non-shaft loosening, while at a depth of 3060 cm rectangular crosssection cavities are created, and the walls of the cavities are rammed. Due to this, meltwater enters through the furrows and collects in the cavities of a large volume and is retained due to the rammed walls for a long time. The use of large volume cavities will increase the amount of accumulated moisture, which will contribute to an increase in the amount of harvest.
CONCLUSION: An improved method is proposed. The novelty of the method lies in the fact that the cavities are formed to a depth of 30 to 60 cm due to low-frequency vibrations at a frequency of 1 stroke per second of planar trapezoidal semi-paws from the sides of the rack, and the sealing of the walls of the cavities is carried out by exposure to high-frequency vibrations with a frequency of 250 Hz using roller elements. The use of large volume cavities will increase the volume of accumulated moisture, which will contribute to an increase in the amount of harvest.
