Study on the Temperature Uniformity of Sprocket Surface Based on Electromagnetic Guidance

Sprockets, as the most important component of chain drives, are widely used in low‐speed and heavy‐duty engineering equipment. Due to the complex contour shape, it is difficult to obtain a uniform temperature layer before quenching, which limits the strength, hardness, wear resistance, and service life of the sprocket. Therefore, the distribution of the temperature gradient of the sprocket in asynchronous dual‐frequency induction heating is investigated. A bilateral arrangement method of magnetizers is proposed to guide the spatial magnetic field distribution and control the surface temperature uniformity of the sprocket. Reinforced and shielded magnetizers are designed, revealing the characteristic effect of the main structural parameters of these magnetizers on the temperature uniformity of the sprocket. The results indicate that using these magnetizers during the medium‐frequency heating stage can change the heat source distribution characteristics at the top and bottom of the sprocket tooth. The sprocket obtains a more uniform temperature layer during the subsequent high‐frequency heating stage. The method reduces the temperature difference of the sprocket tooth profile by 53.2%. It is proven that the designed magnetizers and the bilateral arrangement method effectively improve the uniformity of the temperature distribution of the sprocket.

The Belt and Road Initiative and Urban Entrepreneurship: Evidence From the Opening Policy From China

ABSTRACTEntrepreneurship is a vital source of high‐quality employment in China and is crucial in advancing Chinese‐style modernization. Using panel data from 281 prefecture‐level cities in China from 2003 to 2021, this study employs difference‐in‐differences and double machine learning models to examine the impact of the Belt and Road Initiative (BRI) on entrepreneurship. The research findings are as follows: The BRI implementation significantly enhances entrepreneurship at city and provincial levels, with results remaining robust across various tests. The BRI promotes entrepreneurship through industrial innovation, digital trade development, and economic agglomeration. Heterogeneity analysis reveals that the BRI's positive effects on entrepreneurship are more pronounced in small and medium‐sized cities and central and western regions. Furthermore, the BRI exhibits significant spatial spillover effects, stimulating entrepreneurship in neighboring cities. The initiative also effectively reduces relative disparities in entrepreneurship across regions, particularly between eastern, central, and western areas, thus promoting coordinated regional development. Additionally, triple‐difference results indicate that the BRI's positive effects on urban industrial innovation are mainly concentrated in manufacturing sectors such as energy, equipment, and information technology. This study complements the BRI's effects and provides policy implications for narrowing regional entrepreneurship gaps and promoting high‐quality full employment in China.

It is generally recommended that there is a need to increase the class hours, provide technological equipment, and appoint ESP trained instructors for the efficient teaching of medical English.

Optimizing vaccine uptake in sub-Saharan Africa: a collaborative COVID-19 vaccination campaign in Madagascar using an adaptive approach

BackgroundThe COVID-19 pandemic has highlighted the need for more effective immunization programs, including in limited resource settings. This paper presents outcomes and lessons learnt from a COVID-19 vaccination campaign (VC), which used a tailored adaptive strategy to optimise vaccine uptake in the Boeny region of Madagascar.MethodsGuided by the Dynamic Sustainability Framework (DSF), the VC implementation was regularly reviewed through multi-sectoral stakeholder feedback, key informant interviews, problem-solving meetings, and weekly monitoring of outcome indicators to identify and apply key adaptations. Qualitative data on processes were collected and analysed using a rapid assessment approach. Outcome indicators, including pre- and post-VC vaccine hesitancy and trends in vaccine doses administered, were analysed using generalized linear models. Additionally, vaccination coverage, geographic reach, and target population characteristics, and sustainability indicators, such as staff trained, facilities equipped, and degree of integration of operational and educational materials were also tracked.ResultsKey strategy adaptations included using a proactive campaign approach, community-led awareness and outreach, particularly in remote areas, and addressing cold chain, waste management, vaccine transport, and information technology (IT) equipment gaps. Over six months, 24,888 COVID-19 vaccines were administered. The adapted strategy led to an 8% increase in doses administered weekly (RR = 1.08, CI 95%: 1.01-1.15). However, vaccine hesitancy among the unvaccinated population remained unchanged (∆ = 0.02, CI 95%: -0.04-0.08). In terms of sustainability, 340 staff were trained, and 10 primary healthcare facilities were equipped and refurbished.ConclusionsImplementing collaborative, multi-sectoral vaccination strategies that integrate healthcare services with proactive outreach and community-driven campaigns are effective in increasing vaccine coverage in resource-limited settings. It demonstrates how theory-based adaptive strategies can enhance vaccination rates, even if they do not significantly impact COVID-19 vaccine hesitancy within the community. More generally, this initiative has important implications for adult vaccination programmes other than those related to COVID-19.

Manufacturing and decorating cardial pottery: shell tools at the Neolithic site of Cabecicos Negros (Vera, Almeria, Spain)

Traditional research approaches on pottery production based on typological and morphometric classifications have changed in favour of new lines of research. One of them is based on the study of the technological equipment used in ceramic manufacturing processes. For example, ethnographic evidence shows the use of shell tools as technological equipment in different phases of ceramic production. In this study, the methodology of use-wear analysis has been applied to the archaeomalacological material from the Neolithic site of Cabecicos Negros (Andalusia, Spain) to establish if the shells were used as work tools. This analysis has been completed with the development of an experimental program composed of two analytical and one prospective experiments, carried out to provide new data about the cardial decorative technique and to define the use-wear traces that appear on the active area of the shells after their technological use. The results obtained in this investigation show the use of shells in different stages of pottery production. On the one hand, during the modelling and regularization phase of the ceramic surface and, on the other hand, during the cardial decorative phase. In this way, through this work, it has been possible to establish that the archaeological site of Cabecicos Negros was a pottery production center where domestic pieces were made during its Neolithic occupation. In addition, these findings reaffirm the importance of shells in ceramic manufacture during the Neolithic period, mainly in terms of the technical process linked to the cardial-type of ceramic decoration.

Multidisciplinary and multiprofessional care to multimorbid chronic patients with cardiovascular disease: the experience of the Azienda Sanitaria Universitaria Giuliano Isontina

The world of chronic non-communicable diseases is progressively growing epidemiologically, requiring a significant commitment of resources, continuity of care, and strong integration between healthcare professionals and care settings. The National Recovery and Resilience Plan, in the Ministerial Decree 77 of 23/5/2022, identifies Community Homes as the privileged location for providing integrated, multidisciplinary and multiprofessional interventions, involving specialists and nursing clinics, general practitioners and district structures, utilizing all the necessary technological equipment, including digital platforms for telemedicine. In this context, cardiology is facing a complicated challenge: cardiologists must take care of patients with cardiovascular diseases who have also complex comorbidities and are required to extend their knowledge beyond the specific, sometimes super-specialistic, cardiovascular field, to avoid fragmentation, redundancy, and potential conflicts in the diagnostic-therapeutic care pathways. The Territorial Specialist Department, recently created in the Azienda Sanitaria Universitaria Giuliano Isontina, aims to promote the so-called "value-based medicine", that is, an effective yet sustainable medicine in both economic and social terms, reconciling guidelines with the actual needs of the patient. The ultimate goal is to implement an initiative-based medicine program with systematic stratification of patients at greater risk/complexity for a more efficient, appropriate and sustainable clinical governance.

BASIC APPROACHES TO IMPROVING THE TACTICAL AND TECHNICAL CHARACTERISTICS OF OF LIGHTLY ARMORED VEHICLES BY SUBSTANTIATING THE STRUCTURE AND PARAMETERS OF ARMORED HULLS BY DYNAMIC CHARACTERISTICS

Domestic lightly armored vehicles and robotic combat platforms based on them, as the experience of combat operations against the aggressor country shows, are subjected to intense dynamic loads that tend to grow constantly. This makes it necessary to pay attention to ensuring more rigid dynamic characteristics of the armored hulls of these vehicles as their main power and protective elements. In turn, this ensures the durability, protection, and accuracy of fire from their own weapons. To this end, parametric models and methods are being developed, and research is being conducted to substantiate the structure and parameters of the armor hulls of lightly armored vehicles and robotic combat platforms based on them, which ensure their strength, protection, and accuracy of fire. To this end, fundamentally new approaches to the analysis and synthesis of eigenfrequency spectra and waveforms of complex mechanical systems are being developed based on the improvement of the Rayleigh's variational principle. The substantiated technical solutions are implemented in the modernization of armored hulls of domestic vehicles and robotic combat platforms based on them, etc. Such knowledge and methods have, on the one hand, a fundamental nature, and, on the other hand, direct application in the field of armaments and military equipment. In addition, such knowledge is applicable to the development of new machines, equipment and devices for the energy industry, transport, technological equipment, etc. At the same time, new non-traditional materials, strengthening technologies and composite structures are naturally taken into account, used and substantiated. Accordingly, these knowledge, methods, and technologies are the basis for substantiating progressive scientific and technical solutions.

Tractor-free agriculture is an intersectoral end-to-end technology of agriculture

The article presents a new technological direction – «tractor-free agriculture». Its advantages are proved and the attributes that translate this technological direction into the category of intersectoral end-to-end technology are determined. The paradigm of «tractor-free farming» declares the rejection of the use of classic tractors of traction and traction-energy concepts and defines the transition to mobile energy modules-transformers of the energy concept. The principles of the energy concept determine the maximum possible use of engine power for useful movement and execution of work processes, which ensures high efficiency of «tractor-free farming». The use of sets of mobile power transformer modules of electric drive type, complete with technological modules, instead of tractors, ensures maximum technical and technological equipment of agricultural industries for all conditions and various technological operations. The authors have proved that «tractor-free farming» is the most effective in the field of industrial horticulture and nursery farming, characterized by a wide range of conditions and a variety of technological operations performed. The article provides examples of basic configurations and technical appearance of «tractor-free farming» products for the industrial horticulture and nursery industry. The intersectoral nature of the new technological direction makes it possible to effectively use products of «tractor–free agriculture» in other sectors of agriculture – vegetable growing, breeding and seed production, as well as in municipal and urban logistics. An example of the practical implementation of individual fragments of «tractor-free farming» products in industrial gardening can be an existing model demonstrator of a garden e-Drone, with the pilot name «Russian Shuttle», created at the INTECH Engineering Center of the Michurinsk State Agrarian University. This product with a load capacity of up to 1000 kg and an operating speed from 0 to 30 km/h is designed for harvesting and transporting fruits. A distinctive feature of the Russian Shuttle garden drone is the use of 2 mass–produced electric drive bridges with a capacity of 1.2 kW, which significantly reduces its cost (by 10 times) compared to existing foreign self-propelled garden platforms.

Device for calibration of hot air welding machines

Plastics hot air welding techniques involve measuring and maintaining certain values of three physical quantities: temperature, clamping force and the dwell time of the product under load. Technical regulations of the last century do not specify the clamping force value. The value was kept by the mass of the active element of the technology equipment only. The paper considers the newly developed and studied device for calibration of hot air welding machines by clamping force. The device provides calibration of various types of machines with an operating gap of 13 mm and more. The calibration device itself was calibrated by the method of loading with standard weights using a special device. The functioning of the controller board adder was also studied, which allowed controlling the clamping force characteristics of hot air welding machines in case of inhomogeneous distribution of force and non-ideal geometric shape of clamping elements. It is shown that the new device allows controlling one of the main characteristics of hot air welding machines of various designs and manufacturers. The device made it possible to periodically control the actual value of the clamping force of the active element of the machine during the technological process realization. If in a specific model of the machine the measured value is the pressure in the pneumatic system instead of the clamping force, then during the initial calibration the clamping force against the pressure in the pneumatic system matrixes is generated, and its stability is then controlled.

ORGANIZATIONAL STRUCTURE OF THE IT DEPARTMENT THE INSTITUTION CARE OF HEALTH

The paper considers the problem of studying the organizational structure of the IT department of a healthcare institution. Connecting a healthcare institution to the Electronic Healthcare System is one of the mandatory conditions of the Ministry of Health of Ukraine for concluding agreements with the National Health Service of Ukraine and transitioning to cavitation, which, in turn, requires a significant amount of computer equipment that constantly uses communication technologies and works with a significant amount of information (databases). The regular work of the entire complex requires the participation of a relevant specialist, and, given the scale of the institution, a relevant structural unit responsible for the work of computer equipment and information technologies (IT services). Given the current organizational structure of the institution, it is proposed to subordinate the department to the Deputy Director General. The head of the department is responsible for the system's performance within the functional scope of the Director General and his deputies and manages the specialists of the department. Each of the specialists is responsible for the functioning of the system within the assigned department. Such a functional division allows to clearly defining the areas of responsibility of each employee. The planned organizational structure of the IT service is divided into functional and support parts. The functional part ensures the functioning of the information system within the main departments and auxiliary services and consists of relevant specialists assigned to the structural unit. The support part is responsible for the operation of the information system of the institution as a whole, the administrative and economic complex and carries out general administration and current technical maintenance of the information system of the healthcare institution. The paper proposes an organizational structure of the IT department of a healthcare institution, the functional content of which depends on a specific medical information system from the list of recommended by the Ministry of Health. The possibilities of assessing the efficiency of the department and effective indicators are determined. The directions of further research into the process of digitalization of the activities of healthcare institutions are outlined.

Algorithm of calculation of water consumption on dairy cattle farm with tied and loose housing at milking in milking parlors

Water is used in the whole cycle of milk production, from watering and fodder preparation to washing of milking equipment and milk cooling tanks. At the same time, farms do not control and record the amount of water consumed, which can result in a significant excess of actual water consumption over the normative data. One of the ways to solve this problem can be the introduction of a water consumption monitoring system, which will track the actual water consumption on the farm and compare it with the calculated volume obtained on the basis of normative data, technical characteristics of equipment and animal husbandry technology adopted in the farm. The purpose of the research is to develop an algorithm for calculating water consumption when performing technological operations on cattle dairy farms. As a result of the research, an algorithm for calculating water consumption for technological operations was developed, taking into account different variants of the technical and technological solutions. On the basis of the algorithm a program was developed, with the help of which the sequence of water consumption calculation was tested. The calculation was carried out for a farm for 800 heads of dairy herd of loose housing with productivity of 28 kg/head and 200 heads of loose housing with productivity of 32 kg/head excluding young stock. Water consumption for such a farm is 113.09 m3 /day, of which 99.92 m3 /day is used for watering, fodder preparation, and is non-returnable, and 13.17 m3 /day is used for technological operations. The further direction of research will be the development of a monitoring system based on the developed program of water consumption calculation. In addition to the monitoring system, the program will be useful in technological design of cattle farms for milk production.

Planar Two-Dimensional Vibration Isolator Based on Compliant Mechanisms

In practical engineering applications, the vibration is often generated in various directions and can be harmful to the engineering equipment. Thus, it is necessary to develop vibration isolators that can reduce vibration in multiple directions. In this paper, we propose a planar two-dimensional vibration isolator based on compliant mechanisms. The proposed mechanism consists of two negative stiffness-compliant modules and two positive stiffness-compliant modules, which leads to the quasi-zero stiffness (QZS) property in the mechanism. The dynamic model is established by using the third-order Taylor expansion and the harmonic balance method. Based on the dynamic model, the influence of different parameters on the displacement transmissibility is discussed, including damping ratio, system stiffness, and excitation amplitude. Finally, we conducted the vibration isolation experiments and obtained the displacement transmissibility of the isolator. The results verify that the proposed isolator has good isolation performance for low-frequency vibration.

Effects of Vibratory Stress Relief on Microstructure and Mechanical Properties of Marine Welded Structures

Dissimilar steel welded structures are commonly used in the marine engineering field. Owing to the scarcity of in-depth investigation into the intricate pattern of residual stress distribution in welding within 316L/Q345 dissimilar steel welded joints and methods for reducing this stress, a platform-based vibratory stress relief (VSR) experimental system was established to comprehensively study the effects of VSR on the mechanical properties and microstructure of 316L/Q345 welded structures. Scanning electron microscopy (SEM) was used to examine the fracture morphology and explore the intrinsic mechanisms by which VSR enhances the mechanical properties of welded joints. The findings suggest that VSR is capable of significantly homogenizing and diminishing the welding residual stress within the heat-affected area of 316L/Q345 mismatched steel welded specimens. The significant reduction in residual stress after VSR can primarily be attributed to the combination of alternating stress applied by the VSR platform and the welding residual stress, which exceeded the yield limit of the metal materials. Furthermore, the significant reduction in residual stress, refinement of second-phase particles, and changes in fracture mechanisms are the main reasons for the increased strength observed after VSR. This study has significant engineering application value, providing a theoretical basis for the use of VSR treatment to enhance the reliability of the safe operation of marine engineering equipment.

СТАТИЧЕСКИЙ СМЕСИТЕЛЬ ДЛЯ КОНТРОЛЯ ПРОЦЕССА ЗЕРНОСУШЕНИЯ

The purpose of the study is to improve the technology of mixing grain samples using a patented manufactured static mixer. Tasks: to study the technology of grain mixing in a multi-stage static mixer; determine the uniformity and homogeneity of mixing. Materials are given based on the results of a study of the formation of average samples from a batch of grain that have undergone moisture removal on grain drying equipment to a moisture content of 14 %. Experimental studies on the formation of an average sample were carried out using new technological equipment, copyrights are protected by a utility model patent of the Russian Federation No. 202890 "Static laboratory mixer".

As a result of mixing on the developed mixer, 4 samples of medium samples were obtained, the content of which showed that the composition of the mixed samples contains the required amount of grains from point samples with a deviation: in 1 sample +1.2 %; in the second sample – 1.2; in the third sample – 0.6 and in the fourth sample +0.6 %, which corresponds to the standards of ±5 %.

STUDY OF EXPRESSING OF OIL-CONTAINING RAW MATERIALS ON A SCREW PRESS

The object of the research is the technological process of pressing oil from oil-containing raw materials with a laboratory screw oil press OR-600M. An analysis of scientific and technical information on obtaining oil by mechanical pressing was carried out. Vegetable oil is a food product that is in great demand among people. Unrefined cold-pressed first-pressed oils were obtained from ten types of oilseeds: sunflower, sesame, peanut, mustard, pumpkin, rye, flax, hemp, rapeseed, corn. The oils obtained by the cold pressing method are characterized by low peroxide and acid values and are suitable for food consumption while preserving their valuable quality. It was analyzed that the oil content of the studied raw materials is at least 12 % for corn germs, and the maximum oil yield is 54 % for sunflower. The productivity of the screw oil press was determined experimentally and the minimum productivity of the press was established, which is 401 g/h for corn germs, and the maximum productivity for sunflower is 1522 g/h. The quantitative content of oil in oil-containing raw materials was calculated and determined: the minimum yield of oil is 10,12 % for corn germs, the maximum yield of oil is 50,74 % for sunflower. It was also found that with an increase in the productivity of the screw press, the output of oil increases. The main features of using the press are characterized, including the simplicity of the technological equipment, low energy consumption of the technological process of pressing, requirements for a small area of use. The ratio of fatty acids in the studied oils was substantiated and it was found that the content of polyunsaturated fatty acids and monounsaturated fatty acids, the consumption of which contributes to strengthening human health, prevails. The obtained results of the research of the range of oil raw materials on the screw press are expedient to use in the production technology of vegetable oils of increased biological value, dietary supplements and cosmetics.
