Appropriately matching transport care units to patients in an interhospital Transport Care: an implementation report.

In interfacility transport care, a critical challenge exists in accurately matching ambulance response levels to patients' needs, often hindered by limited access to essential patient data at the time of transport requests. Existing systems cannot integrate patient data from sending hospitals' electronic health records (EHR) into the transfer request process, primarily due to privacy concerns, interoperability challenges, and the sensitive nature of EHR data. We introduce a distributed digital health platform, Interfacility Transport Care (ITC)-InfoChain, designed to solve this problem without compromising EHR security or data privacy. This report details the implementation of Interfacility Transport Care (ITC)-InfoChain, a secure, blockchain-based platform designed to enhance real-time data sharing without compromising data privacy or EHR security. The ITC-InfoChain platform prototype was implemented on AWS cloud infrastructure, employing Hyperledger Fabric as a permissioned blockchain. Key elements included participant registration, identity management, and patient data collection isolated from the sending hospital's EHR system. The client program submits encrypted patient data to a distributed ledger, accessible to the receiving facility's critical care unit at the time of transport request and EMS teams during transport through the PatienTrack web application. Performance was evaluated through KPIs such as data transaction times and scalability across transaction loads. The ITC-InfoChain demonstrated strong performance and scalability. Data transaction times averaged 3.1 seconds for smaller volumes (1-20 transactions) and 6.4 seconds for 100 transactions. Optimized configurations improved processing times to 1.8-1.9 seconds for 400 transactions. These results confirm the platform's capacity to handle high transaction volumes, supporting timely, real-time data access for decision-making during transport requests and patient transfers. The ITC-InfoChain platform addresses the challenge of matching appropriate transport units to patient needs by ensuring data privacy, integrity, and real-time data sharing, enhancing coordination of patient care. The platform's success suggests potential for regional pilots and broader adoption in secure healthcare systems. Stakeholder resistance due to blockchain unfamiliarity and data privacy concerns remains. Funding has been sought to support a pilot program to address these challenges through targeted education and engagement.

Tracking the European transition from fuel dependence to sustainable mobility

This study aims to track the EU’s shift from fuel dependence to sustainable mobility, assessing current impacts and future efforts for low- and zero-emission vehicles and renewable fuels to reduce crude hydrocarbon imports and greenhouse gas emissions. The paper uses methods of composite indices of fuel dependence and greenhouse gas emission intensity, decomposition analysis for crude hydrocarbon imports and greenhouse gas emissions, and the causal relationship between transport traffic and sustainable mobility objectives. Empirical results indicate that deploying sustainable mobility in the EU saved 10 million tons of crude oil imports and prevented 49 million tCO2eq emissions. Advancements in sustainable mobility were more effective in curbing greenhouse gas emissions (4.7%) than in reducing crude hydrocarbon imports (1.9%) from 2013 to 2022. Projections for the EU’s 2025 objectives indicate significant efforts needed to avoid an extra 61 million tCO2eq, including adding over 13 million zero-emission transport units and producing about 2 million tons of sustainable fuel. Both targets are currently at risk. The study highlights the latent potential in other hydrocarbons that can be transformed from non-fossil energy sources. Therefore, monitoring the impact of sustainable mobility is a crucial task in reducing fuel dependence and greenhouse gas emissions from transport. It enables informed decisions and strategy adaptations and ensures that environmental and economic targets are met both timely and effectively.

Modeling and analysis of fluid-solid coupling heat transfer and fluid flow in transonic nozzle

Solid rocket motors (SRMs) are the power units of modern aerospace transportation, and it is of great significance to predict their flow and heat transfer characteristics by numerical simulation. This numerical study is based on a self-developed code framework MHT (Multi-X Heat Transfer, where X represents the region, scale, physical field, and other aspects) and presents an effective method of analyzing fluid–solid coupling heat transfer problem in an axisymmetric supersonic nozzle. For the nozzle wall heat conduction and nozzle-in fluid flow there are two kinds of solution methods, the detached (solved separately in solid and fluid region and them coupling at the interface) and the whole field method (solve the conduction and convection simultaneously). The whole field method is more efficient but few scholars use it to solve the nozzle coupled problem. This paper introduces the numerical details of the whole field solution method, and provides a new idea for the coupling solution of the nozzle. In addition, a mixed grid system is proposed around the interface region of fluid and solid, in which the quadrilateral structured mesh is used at the fluid side, and the triangular unstructured mesh is used for the outer fluid region and the whole solid region to ensure the accuracy of the 1st-oder normal derivatives calculation. The self-developed code is validated by comparison with well-known commercial soft-ware. Transient results of temperature and velocity are presented for the instants of 1st 20 and 40 s of a practical nozzle.

A fully integrated wireless microfluidic immunosensing system for portable monitoring of Staphylococcus aureus

The advanced devices that function fully without the need for external accessories are regarded as a pinnacle goal in the design and construction of modern ones. Staphylococcus aureus (S. aureus), a prominent human pathogen, is responsible for causing a wide variety of infections and chronic diseases. Herein, we present the first instance of a fully integrated wireless microfluidic immunosensing system (FIWMIS) capable of conducting point-of-care S. aureus monitoring in real samples of S. aureus-spiked commercial purified drinking water and S. aureus-spiked watermelon juice. The development of the proposed FIWMIS became a reality by conquering significant engineering hurdles in seamlessly integrating a microfluidic unit for liquid sample transport without the need of an external pump, an immunosensing unit for S. aureus monitoring, and an electronic control unit for signal conversion and wireless transmission. Such full integration culminated in a FIWMIS that upholds its pump-free, wireless, and low-cost characteristics for portable monitoring of S. aureus.

АЛГОРИТМ ЭКСПЕРСС-ОЦЕНКИ ВОЗДЕЙСТВИЯ НА ПОЧВУ ХОДОВЫХ СИСТЕМ ПРИЦЕПНЫХ ТРАНСПОРТНЫХ СРЕДСТВ

A reliable assessment of the level of impact on the soil from the propulsors of mobile agricultural machinery is possible only with an accurate measurement of the contour area of the contact surface of the tire with the support base. This indicator underlies all standard methods for determining the maximum normal pressure, maximum stresses and other indicators in the “wheel-soil” system. A simplified algorithm for determining the area of the contact patch of tires, which can be used both when assessing the level of pressure on the soil of existing trailed agricultural vehicles and newly developed ones, was proposed by the authors. In the first case, it is enough to measure the dimensional parameters of the tire mounted on the trailer: diameter, profile width, the amount of deformation under the influence of axial vertical load. In the second case, it is enough to take this data from catalogs with the technical characteristics of tires from specific manufacturers. The mathematical model used to determine the crosssectional area of the cylinder by the plane of the supporting surface located from the edge of the wheel at a distance equal to the tire deflection is the basis of the algorithm. The proposed methodology was tested by comparing the calculation results with the results of full-scale tests of 22 samples of agricultural tires installed on various types of transport and tractor units: carts, trailers, transfer bins. As a result of the research, a fairly high value of the modeling efficiency criterion was obtained (0.989), indicating a high level of convergence between the predicted (calculated) and observed (measured) values of the contact areas of the studied tire samples. Ease of use, versatility and accuracy sufficient for engineering calculations make the proposed algorithm convenient for wide practical use.

Volatile organic compounds (VOCs) in urban public transportation: Seasonal influences and variations

The present work aims to analyze the information related to the organic pollutants present inside the public transport units of León Guanajuato, Mexico, along winter, spring and fall seasons. Through the application of different selection criteria, a database was generated that allowed the analysis of the different selected pollutants and determine their behavior throughout the spring, autumn and winter seasons. These analyzes were carried out using different statistical tools like ANOVA, PCA, and correlation network maps. At least 23 compounds were selected as common pollutants along all the seasons, including aromatics, aliphatic, halogenated, polycyclic, and compounds with heteroatoms species. Results showed that the concentrations of Volatile Organic Compounds s such as hexane (1.5–3.0 µg/m³), dichlorobenzene (2.0–4.5 µg m−3), and toluene (5.0–12.0 µg m−3) varied significantly across the seasons, with higher levels observed in winter. The study highlights the influence of external environmental factors on indoor air quality within public transport units proven through statistical analysis. The results allowed to mention that the concentrations of Volatile Organic Compounds can vary significantly in different season along the year, as well as that the main pollutants vary according to the season, of which there are compounds that are only present during these periods.

Periodically Twisted Molecular Wires Based on a Fused Unit for Efficient Intramolecular Hopping Transport.

Realizing efficient long-distance intramolecular charge transport based on a hopping mechanism is a key challenge in molecular electronics. In hopping transport, a smaller reorganization energy (λ) and energy difference between hopping sites (ΔEhs) should lead to a smaller activation energy and faster charge transfer. However, the development of π-extended molecules that meet these requirements is challenging. In this study, we successfully synthesized several nanometer-scale π-extended molecules composed of a fused π-conjugated unit as a hopping site for reducing λ. Conformational twists between fused units effectively localize π-conjugation in each unit, contributing to reducing ΔEhs. The expected electronic structures of the oligomers were confirmed using spectroscopic and electrochemical measurements. Single-molecule conductance measurements exhibited higher conductance and lower activation energy than those of nonfused oligothiophenes. First-principles calculations indicated that smaller λ and ΔEhs values explain the high conductance. These results highlight the efficiency of the proposed molecular design for effective intramolecular hopping transport.

Directive transportation in smart cities with line connectivity at distinctive points using mode control algorithm

This article examines the operational functionality of intelligent transport systems to enhance smart cities by reducing traffic congestion. Given the increasing populations of smart cities, there is a growing demand for public transit systems to address the issue of traffic congestion. Therefore, the suggested system is developed using a few parametric design models, which combine point-to-point protocol and mode control optimization. The multi-objective parametric design for a smart transportation system is conducted using min–max functions to minimize the waiting time period for end users. Furthermore, customers are given the option to utilize a line following mechanism that offers suitable connectivity, along with independent identification and revitalize functions. The predicted model effectively eliminates the delay produced by transportation devices when positioning units are involved, ensuring that individual messages are delivered without any interruptions. In order to evaluate the results of the proposed system model, four different scenarios were examined. A comparison analysis revealed that the suggested method achieves a suitable directional flow for 96% of smart transport units. Additionally, it reduces delays and waiting periods by 2% and 6% respectively, while increasing energy consumption by 29%.

Novel bipolar host materials based on benzimidazole-hybridized phenanthridine for efficient red PhOLEDs

In this work, two innovative bipolar host materials, TPA-BIP and Cz-BIP, were designed and synthesized based on benzimidazole-hybridized phenanthridine (BIP) moiety as the electron transport unit. Compared to the widely used electronic transport unit benzimidazole, the BIP unit possesses a large planar rigid structure that can effectively enhance the thermal stability and the electron transfer capability of materials. Both materials exhibit good thermal stability respectively with Tg of 113 °C and 141 °C, proper HOMO/LUMO energy levels, and balance carrier transport capabilities. The red phosphorescent organic light-emitting diode prepared based on both materials achieve relatively high luminescence efficiency and relatively low efficiency roll-off. In particular, the EQEmax of the R1 device using TPA-BIP as the host material reaches 21.5 %, which is more superior than that of the conventional host material CBP (EQEmax of 9.84 %). Even at 1000 cd/m2, the device still achieves an EQE of 21.3 % with virtually no decrease. In conclusion, the results demonstrate the broad development potential of these BIP-based host materials for red PhOLEDs applications.

Исследование процесса подачи сеносоломистого материала в приемную камеру пневмопогрузчика уборочно-транспортного агрегата

The article is devoted to the design of the working parts of a harvesting and transport unit (HTA), which operates as a result of the joint work of a pick-up and a pneumatic loader with an assembly chamber. The parameters of their relative position are considered, ensuring the technological process of continuous transportation of plant mass into the assembly chamber. For this purpose, an analysis of the process of moving material along a belt loader and its subsequent dumping into the receiving chamber of a pneumatic loader was carried out. Analytical expressions have been obtained that make it possible to calculate the parameters of the relative position of the pick-up shafts and the loader rotor and the area of mass supply to the loader. The calculated trajectories of particle movement after leaving the belt conveyor at an angle of inclination to the horizon of 20 were constructed; 30; 40 degrees. It has been established that the working parts of a pneumatic loader (rotor blades) can be located within the mass ejection zone, i.e. 0.2-0.3 m from the point where the mass is released from the conveyor, since at these points of the trajectory the speed of movement of the material is maximum.

Eliminating the Occurrence and Consequences of Toxic Release in Petrochemical Industry through Intervention of Safety Engineering Tools

The aim in this project is to analyze the risk associated with different toxic releases which is occurring in the chemical industry and to minimize its release using safety engineering tool in order to make the working environment safer. The sector of petrochemical industries is very important and have specific place in our country. Since the beginning, the Indian petrochemical industry has shown an enviable growth rate. This industry also contributes largely to the economy of the country and the growth and development of manufacturing industry as well. Petrochemical industry has a high risk of toxic release. The main causes of accidents are the chemical splashes which can occur for instance when a pipe or a tank burst under pressure or during disassembling operations of pipes or valves. There are a number of ways of toxic release at each and every process of petrochemical industry. We have identified the way in each process of the petrochemical industry. We have taken H2S as toxic gas and performed analysis, with the help of Bowtie methodology. Result obtained by evaluating various processes in petrochemical industry, we found that H2S can be released in three major sections i.e. transportation, storage and processing units. Using bowtie method, resolutions has been done to decrease or eliminate the possibilities of leakage of H2S

Bearing Steel Structures for Installation of Railway Strain Gauge Scales

Purpose. The main purpose of the publication is to compare the main technical and economic indicators of the two proposed structural variants of the support system for railway strain gauge scales for four-axle wide gauge railcars. This is due to the need to reconstruct and modernize the fixed assets of an industrial enterprise, in particular, to overhaul and replace old railway scales with modern electronic strain gauge scales. Also, the purpose of the work is related to the need to expand the range of railway cars for which the possibility of weighing is provided, including transport units of the foreign car fleet. Methodology. To achieve this goal, we analyzed the modern types of railroad cars for freight transportation, determined the main components of strain gauge scales for weighing the main types of cars, and developed a special support system to support the scale platform. The support system is provided in two design variants - with one spatial support frame and two separate flat support frames. Using the domestic design and computing complex SCAD, we built finite element models for both proposed design options. Based on the analysis of their stress-strain state, rational cross-sections were selected for each structural element, and the total mass was determined. Findings. A comparative analysis of the two developed structural solutions for the support system for modern railway strain gauges has revealed that the variant with two separate bearing frames has a lower weight by about 40 % compared to the variant with one spatial bearing frame. However, the manufacturability of its production is somewhat lower, since it involves 10 structural elements compared to 7 for variant No. 1. Originality. The numerical analysis made it possible to theoretically substantiate a more rational and efficient design solution for the support system for modern railway strain gauge scales. Practical value. A constructive variant of the steel support system has been developed and proposed for practical implementation, which is the most effective in terms of its technical and economic indicators for the existing conditions of an existing industrial enterprise. The developed design option was also coordinated with the project of major reconstruction of the building for weighing railroad cars.

Boosting Hole Mobility: Indenofluorene-Arylamine Copolymers and Their Impact on Solution-Processed OLED Performance.

We introduce three newly designed thermally cross-linkable hole transport copolymers (PIF-TPD, PIF-F2PCz, and PIF-TPAPCz) for improving the performance of solution-processed organic light-emitting diodes (s-OLEDs). These copolymers, designed through a strategic molecular approach with benzocyclobutene (BCB) and styrene-based cross-linking monomers, show high solvent resistance at a low cross-linking temperature (150 °C). Furthermore, these conjugated copolymers based on planar indenofluorene with three different hole transport (HT) units, exhibit outstanding charge carrier mobility (1.61 × 10-2 cm2 V-1s-1), demonstrated by comparing hole reorganization energy and electronic coupling strength of HT units. Despite these copolymers showing the overall vertical orientation in the horizontal dipole moment measurement results, we demonstrated that the HT units can exhibit the preferred orientation, contributing to high hole transport properties. As a result, they perform exceptionally well as hole transport layers in green phosphorescent s-OLEDs, achieving a maximum external quantum efficiency of 15.3% and a maximum current efficiency of 53.9 cd A-1 with a small efficiency roll-off despite their relatively low triplet energy levels. These results are comparable to vacuum-deposited OLEDs, highlighting the potential of these copolymers in advancing OLED technology for display panels and lighting applications.

Design and fabrication of Zr-based MOF photocatalyst with functionalized moieties for CO2 reduction and coupling selective oxidation of benzyl alcohol

Zirconium-based metal organic frameworks (Zr-MOFs) are considered as promising photocatalysts due to their excellent stability, unique pore structure, and versatile photocatalytic applications. To strengthen the visible-light absorption, a well-designed targeted MOFs photocatalyst was fabricated by a solvothermal method with Co-tetrakis (4-carboxyphenyl) porphyrinate (Co-TCPP), 1,3,6,8-tetra(4-carboxyphenyl) pyrene (TBAPy), and Zr clusters as sensitizer, ligands and active sites, respectively. Benefiting from the excellent photo-responsiveness of Co-TCPP, the robust catalytic ability of Zr clusters, the promising electron transfer ability of pyrene moiety, the prepared Zr-Co MOF@TBAPy exhibit excellent photocatalytic performance and stability. A high reduction rate of 127.42 μmol g−1 h−1 from CO2 to CO, this is 3.5 and 2.8 times that of Zr-TBAPy and Zr-Co MOF, respectively. The photocatalytic performance of CO2 reduction coupling with selective oxidation of benzyl alcohol (BA) to benzaldehyde (BD) was also tested. The transferring pathway of photogenerated electron from the photosensitive unit to the active site mediated by the electron transport unit was further confirmed by density-functional theory (DFT) calculations, providing intuitive insights into the catalytic mechanism. This work manifests that well-designed MOFs integrated with functional moieties is a feasible strategy for developing high performance MOF based photocatalyst.

Justification of the Use of Container Technology in Dumping

The increase in the depth of the quarry is associated with an increase in the work of quarry transport in limited areas, requires a constant increase in the number of transport units, which increases the environmental burden on the environment. The rock mass extracted from the quarry is stored in external dumps, which occupy large areas and significantly worsen the ecology of the region. The operation of mining equipment on dumps with existing technologies causes a number of problems, the main of which is the movement of equipment near the prism of a possible rock collapse. It is proposed to use container technology for transporting the laying rocks in the dump, where the main element of the technology is a mobile lifting machine, which eliminates the need to build roads or railways on board and on the surface of the dump. Self-unloading of container equipment allows you to pour the rock mass directly to the place of laying on the dump. Containers with rock are installed in front of the front of the dump, and the lifting machine is placed on a special platform of the dump. The rock mass is delivered from the faces by dump trucks of any load capacity and unloaded into the hopper of a plate feeder, which fills the containers as they are fed by a quarry lifting machine. the rock is laid in horizontal layers within the step of moving the lifting machine. The weighted average height of the rock rise is equal to half the height of the dump tier. With the new technology, the entire amount of work will be performed by one lifting machine. Increasing the height of the dump to 80 meters with a new method of dumping, reduce the area occupied by dumps by 175 thousand m2 per year. The use of container technology in the formation of the dump allows, when unloading rock from containers into the dump, to reduce energy consumption during the formation of the dump, and increase the economically advantageous height of the dump. This reduces the area occupied by dumps and reduces the harmful effects of mining on the environment. The article discusses the technology of dumping during the formation of dumps using bulldozers in the conditions of Northern Kazakhstan. Traditional technology involves the involvement of a complex of equipment consisting of 8 dump trucks and 1 bulldozer. According to the new technology, the same amount of work can be done thanks to 1 lifting machine. Based on the calculations carried out, it was found that the intensity of dust emissions from internal sources decreases by 1,576 tons per year. A decrease in dust emissions is also observed with an increase in the height of the dump due to a decrease in area, while the difference was 75.57 tons per year. The total decrease from container technology is 1,651.57 tons per year.

Performance evaluation and user experience of BT-50 transportation unit with automated and scheduled quality control measurements.

Even in the current era of hematology analyzer automation and peripheral equipment, quality control sample measurement remains a manual task, leading to variability in quality control data and increased workload. In this study, we evaluated the performance of quality control measurement using the BT-50 Transportation Unit (BT-50, Sysmex, Kobe, Japan), equipped with a scheduled automatic quality control function, to ensure measurement accuracy and streamline the workflow of hematology testing. We evaluated the automatic measurement performance of quality control samples using the BT-50 for sixrepresentative blood test parameters: WBC (white bloodcell), RBC (red blood cell), HGB (hemoglobin), HCT (hematocrit), PLT (platelet), and RET% (reticulocyte percent). We evaluated the equivalence and compared measurement accuracy between the BT-50 and the manual method. We then compared the variability to other laboratories and confirmed the stability of quality control samples. We also evaluated changes in workflow and staff resources before and after the introduction of the BT-50. The quality control measurement results for the BT-50 and the manual method were found to be equivalent for all six parameters. The variability measured by the BT-50 was lower for some parameters compared to the manual method. Furthermore, the workflow was streamlined by reducing manual processes, resulting in increased efficiency. We confirmed the performance of quality control measurements using the schedule function of the BT-50. Introducing the BT-50 reduced the operator's workload, improved operational efficiency, and promoted the standardization of quality control measurements.
