Microbial necromass and glycoproteins for determining soil carbon formation under arbuscular mycorrhiza symbiosis

Arbuscular mycorrhizal fungi (AMF) form symbioses with most terrestrial plants and critically modulate soil organic carbon (C) dynamics. Whether AMF promote soil C storage and stability is, however, largely unknown. Since microbial necromass C (MNC) and glomalin-related soil protein (GRSP) are stable microbial-derived C in soils, we therefore evaluated how AMF symbiosis alters both soil C pools and their contributions to soil organic C (SOC) under nitrogen fertilization, based on a 16-weeks mesocosm experiment using a mutant tomato with highly reduced AMF symbiosis. Results showed that SOC content is 4.5 % higher following AMF symbiosis. Additionally, the content of MNC and total GRSP were 47.5 % and 22.3 % higher under AMF symbiosis than at AMF absence, respectively. The accumulations of GRSP and microbial necromass in soil were closely associated with mineral-associated organic C and the abundance of AMF. The increased soil living microbial biomass under AMF symbiosis was mainly derived from AMF biomass, and fungal necromass C significantly contributed to SOC accumulation, as evidenced by the higher fungal:bacterial necromass C ratio under AMF symbiosis. On the contrary, bacterial necromass was degraded to compensate for the increased microbial nutrient demand because of the aggravated nutrient limitation under AMF symbiosis, leading to a decrease in bacterial necromass. Redundancy analysis showing that bacterial necromass was negatively correlated with soil C:N ratio supported this argument. Moreover, the relative change rate of total GRSP was consistently greater in nitrogen-limited soil than that of microbial necromass. Our findings suggested GRSP accumulates faster and contributes more to SOC pools under AMF symbiosis than microbial necromass. The positive correlation between the contributions of GRSP and MNC to SOC further provided valuable information in terms of enhancing our understanding of mechanisms underlying the maintenance of SOC stocks through microbial-derived C.

Advancing Carbon Stock Estimation and 3D Tree Modeling: Harnessing the Potential of Low-Cost Backpack LiDAR Technology

Abstract The maintenance of carbon stocks in the forest is fundamental to the global carbon cycle and is essential for informing climate change policy. Traditional methods for measuring carbon stocks have often been labor-intensive and expensive, involving measurements that include DBH, and tree height. However, LiDAR technology provides an efficient alternative for swiftly assessing forest vegetation structure. In this study, a low-cost backpack equipped with LiDAR technology was utilized to create three-dimensional tree models, enabling precise estimations of stem volume and carbon stock. By collecting data on DBH and vertical plant structure, the researchers could produce highly accurate three-dimensional models. The results indicated that the low-cost backpack LiDAR yielded DBH estimates very close to manual measurements, characterized by a linear regression equation of y = 1.0106x - 0.2911 and a coefficient of determination R2 = 0.99822. The results confirmed the high accuracy of DBH measurement using LiDAR, with RMSE in a value of 0.53 cm. This study unequivocally establishes that low-cost backpack LiDAR is an effective tool for measuring biomass and carbon stocks in forests, offering superior monitoring capabilities compared to conventional methods.

Additive manufacturing — a new vector in the production and repair of rolling stock

The influence of the fourth industrial revolution, known as Industry 4.0, on modern industrial production and social life is analyzed. The main advantages of Industry 4.0 are presented, such as increasing productivity and occupational safety, developing new products and materials, as well as increasing the competitiveness of products. Special attention is paid to additive technologies and their role in modern engineering within the framework of the Industry 4.0 concept. The methods of additive technologies, their classification by materials and production methods, as well as their various applications in various industries are described in detail. An example of the successful use of additive technologies is presented on the example of JSC Uralvagonzavod Scientific and Production Corporation, where molds and rods for casting parts with high speed and quality are created using 3D printers. The project of introducing 3D printers into the service depots of the directorate of motor car rolling stock of JSC Russian Railways is considered, with an emphasis on the economic and temporary benefits from the use of additive technologies. The concept of introducing additive technologies in the maintenance and repair of rolling stock involves the creation of support depots on the railway network of JSC Russian Railways. In conclusion, the importance of training highly qualified specialists in the field of additive technologies and the need to develop educational programs to train future employees capable of solving complex tasks of creating and applying new industrial technologies is presented. Special attention is paid to synergetic approaches in education to combine learning with scientific activity and the creation of innovative technological solutions.

A rolling horizon for rolling stock maintenance scheduling problem with cyclical activities

The rolling stock maintenance scheduling problem addressed here involves scheduling a set of cyclical preventive maintenance activities while considering resource capacity and geographically dispersed depots. The objective is to minimize both corrective and preventive maintenance costs using reliability features. We propose to use rolling horizon to decompose the problem into several successive subproblems such that each one tackles the scheduling of only the next cycle of activities instead of all cycles. The scheduled dates to be fixed should be as close as possible to their respective deadlines. Each train can have three status (in service, in maintenance, out of service). The activities deadlines are determined depending on component failure rate which has to be respected otherwise the train becomes out of service. An integer linear programming (ILP) model is proposed to solve the subproblem using a time oriented modeling to get an accurate maintenance cost (preventive and corrective) and respect a minimum of available trains. The rolling horizon allows to build a feasible schedule within a predefined planning horizon for moderate size problems with an interesting trade-off between computation time and solution quality.

Система комплексной диагностики элементов высокоскоростного подвижного состава и инфраструктуры: анализ и внедрение

Objective: to consider the issue of integrated diagnostics of the undercarriage equipment of high-speed rolling stock and track infrastructure, to analyze the impact of operational factors on the technical condition of rolling stock, to identify the main problems and propose possible solutions, to consider the prospects of domestic development in the field of integrated diagnostics of rolling stock and infrastructure. Methods: analysis of design features and impact on train operation safety, criteria and parameters of running stability and passenger comfort of the undercarriage equipment of the high-speed electric train “Sapsan”, description of prerequisites and stages of creation, testing and operation of the system of continuous monitoring of parameters of the dynamic system “undercarriage and track” of electric trains “Sapsan”, analysis of the impact of the main operational factors on the technical condition of the rolling stock undercarriage equipment. Results: the key role of the undercarriage equipment of the Sapsan electric train in ensuring operational safety and passenger comfort has been determined. The necessity of creating and implementing a system for continuous monitoring of dynamic reactions in the system “undercarriage equipment - track infrastructure” has been identified. The results of experimental operation of the prototype of the system in the Sapsan electric trains are considered on the example of research of track sections with increased impact on the rolling stock and problems of running stability of the electric train. It is revealed that vertical accelerations of axlebox units with significant amplitudes allow to reveal vertical irregularities of the track up to 3 m long, and constant registration of increased lateral accelerations of the bogie frame shows the necessity of solving the issues related to the geometry of wheel-rail contact at sinuous movement of rolling stock in terms of conicity. The current state and prospects of development of domestic systems of complex diagnostics are determined. Practical importance: the considered diagnostic system allows to carry out complex analysis of problems of technical condition of undercarriage equipment and infrastructure, to determine interdependence and level of influence of operational factors, which is the way to increase reliability and fault tolerance of rolling stock, operational safety and passenger comfort. Its integration into the digital platform will increase the efficiency of rolling stock maintenance planning and enterprise resource management.

Monitoring the bogie lateral dynamics of a high-speed train through wireless sensor nodes

The condition monitoring of railway vehicles and of the infrastructure (track and overhead equipment) through the use of vehicle-based sensors is becoming a major trend for the railway industry and, to this aim, new rolling stock generations are often natively fitted with numerous sensors. However, older vehicles are not equipped with sensors and monitoring systems so that, considering the long service life of the rolling stock, advanced monitoring and condition-based maintenance techniques can only be applied to a relatively minor portion of the in-service railway fleets. This paper presents results from a research programme aimed at designing and testing an innovative monitoring system based on wireless sensor nodes, suitable for the retrofitting of older rolling stock generations, not natively equipped with advanced sensing and monitoring capabilities. The prototype monitoring system was used to detect the incipient bogie instability, which can be related to degradation in some suspension components or to increase of the equivalent conicity at wheel/rail contact. Different vehicle conditions and the influence of the track were considered in the study. Experimental tests have shown that is possible to identify not only how the vehicle condition is evolving in time but also the effect that maintenance operations like wheel reprofiling may have on the bogie lateral dynamics.

СОВЕРШЕНСТВОВАНИЕ СИСТЕМЫ РЕМОНТА И ТЕХНИЧЕСКОГО ОБСЛУЖИВАНИЯ ПАССАЖИРСКИХ ВАГОНОВ ДАЛЬНЕГО СООБЩЕНИЯ

The existing systems of maintenance and scheduled preventive maintenance of passenger rolling stock used for long-distance passenger traffic with speeds up to 140 km/h are considered. Promising areas for their improvement are identified. A combined repair system is proposed, which provides a uniform approach of the rolling stock to the position of a single technical audit and scheduled preventive maintenance without taking into account its mileage. The replacement of the element base, when the mileage criteria are met, is carried out on repair and equipment tracks or specially equipped positions during the technical preparation of the rolling stock at the initial point. The proposed system, in comparison with existing ones, reduces the need for depot repairs; the cost of carrying out scheduled repairs of cars, the time spent by cars in an idle fleet, and also provides opportunities for additional operation of the car at the operational stage of the life cycle. Also, the proposed system allows regulating the frequency of the element base replacement of passenger cars with a designated service life of 40 years, including them in the mandatory requirements for the necessary periodic replacement during capital repairs of the car every 5 years.

Seasonality as Factor of Logistic Costs Formation

The seasonality of demand for goods and services creates vital issues both for the organization of their production, and for implementation of logistic processes. Seasonal fluctuations, as a rule, negatively affect work of the enterprises that is shown in equipment downtimes, incomplete use production and warehouse, in uneven use of human resources, violation of rhythm of activity, to the unreasonable growth of costs. In logistic activity the seasonality influences a set of its components, including creation and maintenance of stocks, existence of warehouse spaces, number and capacities of sales channels and supply. This influence in much defines fluctuations of values of logistic costs. The article proposes an approach to identifying the presence of seasonality, quantitative characteristics in various periods of the annual cycle, the separation of seasonal and trend components of seasonality dynamics, mathematical and statistical modeling of seasonality in the formation of such costs. A forecast assessment of the future dynamics of costs is carried out. Emphasis is made on the highlighting the seasonal component in the indicators of logistics costs that allows to analyze their dynamics more deeply, improve the quality of management decisions associated with them.

Supporting the Management of Rolling Stock Maintenance with an Ontology-Based Virtual Depot

The railway industry forecasts growth in passenger and freight traffic over the next 30 years. This places additional demands on rolling stock depot facilities, many of which were designed and built before the modern age of information technology. This paper explores the potential of improving the efficiency and effectiveness of rolling stock maintenance management to meet the challenges of the near future, by utilising advanced computing techniques. The objective of the work is to create optimised maintenance plans for a fleet of trains, considering optimal use of resources. As a “glue” for joining up functions and operations, a generic Depot and Vehicle ontology (called the Virtual Depot) is introduced. The ontology captures the structures, relationships, and attributes of objects in the Depot (rolling stock, sensors, depot assets, tools, resources, and staff). The ontology is populated with example company and fleet-specific knowledge using an automated knowledge acquisition method. This paper describes the systematic method for the creation of a Virtual Depot. Two particular aspects are discussed in detail—knowledge acquisition of fleet-specific information obtained from a manufacturer’s Vehicle Maintenance Instruction manuals and the construction of a short-term scheduling process within the Virtual Depot. Our evaluation considers the integrative aspects of the method, demonstrating how the ontological structure and its acquired specific information informs and benefits the scheduling process, in particular with respect to schedule optimisation. Results from an initial case study show there is significant potential to optimise short-term maintenance schedules, and the ability to automatically consider resource availability in short-term scheduling is demonstrated.

Technical Preparation for Scheduled Preventive Maintenance of Double-Decker Rolling Stock

The article is devoted to the study of the process of technical preparation preceding scheduled preventive maintenance of newly commissioned double-deck passenger coaches. The paper considers the main tasks and goals of technical preparation, including the step-by-step process of car repair, as well as repair planning, formation of a range of applied materials, tools, and step-by-step control of work performed during repair and maintenance. Upon identifying features and inconsistencies that arise during technical preparation for repair of double-deck coaches of a new model range, ways to solve them are proposed.The paper considers the main directions in organisation of preventive maintenance in terms of implementation of measures to integrate into the process the features associated with the specifics of the assemblies, parts and materials used in those coaches; main tasks of preparing for scheduled preventive maintenance with regard to provision of workshops, of developing forms, methods and adjusting production processes, as well as of employing small-scale mechanisation tools, and manufacturing devices to speed up the repair process. The processes of carrying out scheduled preventive maintenance are structured allowing development of a process model for repair of a double-decker coaches when they are delivered at maintenance and repair facilities.The study allows regulating and improving the efficiency of technical preparation for repair of double-deck coaches, ensuring higher quality and speed of repair work, as well as effectively assessing the real need for spare parts and materials used during the repair process, since the operation of these coaches provides for a new set of spare parts, materials and elements in comparison with single-deck analogues already manufactured.

Invigorasi Larutan Bawang Merah Terhadap Viabilitas dan Vigor Tiga Benih Padi Varietas Lokal

Rice production in South Kalimantan during January to September 2020 decreased compared to 2019. The use of rice seeds per hectare is generally still not in accordance with the recommendations. The local varieties of rice seeds that cultivated are from last year's cropping season, where storage was not good which could lead to a decrease in seed quality. Shallots contain hormones auxin and gibberellins, can be used as a natural growth regulator. This study used a solution of shallots on three local varieties of rice seeds. The purpose of this study was to provide information on the use of natural growth regulators in shallot solution as an alternative to increase seed viability to become a provider of quality seeds. This research carried out from October to November 2021 at the Production Laboratory of the Department of Agroecotechnology, Faculty of Agriculture, Lambung Mangkurat University. The implementation of the research is making shallot stock solution, seed preparation, seed soaking, seed germination, and maintenance. The method used was qualitative using single factor Completely Randomized Design with three levels of treatment and each treatment consisted of five replications. The results showed that treatment using onion solution invigoration had a significant effects on the parameters of growth uniformity and maximum growth potential of expired local rice seeds of Siam Banjar variety. The highest growth speed and seed germination were found in Siam Saba variety. The highest growth uniformity was found in Siam Unus variety. The highest maximum growth potential is found in Siam Mutiara variety.

The Optimal Transportation Option in an Underground Hard Coal Mine: A Multi-Criteria Cost Analysis

The issue of transport in underground hard coal mines is very rarely described in the literature. The financial aspects of this issue are even less often analyzed. Publications in this area focus on technical issues and the safety of mining crews. More attention is paid to transport in open-pit mines. The above premises and practical needs imply the need to conduct economic analyses of transport systems in underground hard coal mines. This paper is a scientific communication, which presents the concept of a multi-criteria cost analysis as a tool to support the selection of the optimal transportation option in an underground hard coal mine. Considerations in this area have not been carried out in the relevant literature, and the problem of selecting a transportation option is a complex and necessary issue in the practice of underground mines with extensive mine workings. The methodology presented includes five cost criteria (costs of carrying out the transportation task; route expansion costs; rolling stock maintenance costs; depreciation costs; and additional personnel costs). The simultaneous application of criteria relating to utility properties in addition to cost criteria makes it possible to adopt a specific technical and organizational model of the transportation system based on the indication of the optimal solution, resulting from the mathematical construction of functions of objectives relating to utility and cost. The optimal variant of the designed system and configuration of the material transportation system in underground workings takes into consideration the following: (1) seven utility criteria (KU1—transportation task completion time; KU2—compatibility of transportation systems; KU3—continuous connectivity; KU4—co-use with other transportation tasks; KU5—safety; KU6—inconvenience; KU7—operation under overplanning conditions) and (2) five cost criteria (KK1—costs of implementing the transportation task; KK2—costs of route expansion; KK3—rolling stock maintenance costs; KK4—depreciation costs; KK5—additional personnel costs). Based on the aforementioned criteria, two objective functions are built for each option: utility and cost. They present divergent goals; therefore, they are non-cooperative functions. Both utility and costs strive for the maximum. In the developed methodology, an ideal point is usually a fictitious solution representing a set of maximum values among all the achievable values in a set of solutions, but it is impossible to achieve this simultaneously based on all the criteria. This point illustrates the maximum utility and lowest cost among the alternatives considered, which is obviously impossible for any of the variants to meet at the same time, although it indicates the possibilities of the technique and the range of costs. For the developed method, a so-called “PND” nadir point is also determined, representing the least-preferred level of achievement of all goals simultaneously, determined from the set of optimal points in the Pareto sense. The originality of the conceptual considerations undertaken stems from: filling the gap in the economic methodology of complex transportation systems evaluation; embedding considerations in the trend concerning complex transportation systems of underground mines; and focusing considerations on the pre-investment phase, making it possible to optimize costs before expenditures are incurred.

A flow formulation for the rolling stock maintenance scheduling problem

Rolling stock maintenance is a key issue for the railway operations. Planning cyclical maintenance activities is a fundamental aspect of maintenance management, requiring a variety of operational choices. We present a novel flow formulation approach to schedule rolling stock maintenance activities optimising both maintenance costs and train availability. The schedule takes into account cyclical maintenance activities and the decoupling between elapsed and operational time. Limited resource and depot capacity are taken into account together with operational constraints to reflect the real operations of the railway system. The proposed formulation is based on an integer linear programming (ILP) approach, which is solved using a commercial solver on randomly generated realistic instances.

The strategic brand of any company is based on customer orientation. With regard to the carriage component of the transportation process, the consumer expects to meet the needs for technically sound rolling stock on constant basis. Timely high-quality maintenance and repair of freight cars guarantee the quality of transport services. The elimination of losses in the technological process of rolling stock maintenance significantly increases the competitiveness of railway transport and has a positive effect on state economic stability. The controllability optimization of the technological complex of freight cars maintenance and repair inevitably increases the efficiency of the transportation process due to a systematic approach to the organization of work related to the maintenance of the life cycle of rolling stock. Mathematical support tools, including the complex of mathematical methods, models and algorithms applied to solve the problems of rational technological processes organization, and can significantly narrow the search for optimal output and eliminate unnecessary losses when updating technology.

The Downside of Upkeep: Analysing Railway Infrastructure Maintenance Impact on Train Operations in Sweden

Efficient and seamless railway operations depend on the systematic and well-coordinated maintenance of both rolling stock and infrastructure. However, track maintenance, or ‘trackwork’, can cause substantial delays if not properly aligned with train schedules. This study comprehensively investigates how trackwork influences train operations in Sweden. It involves an in-depth analysis of an extensive dataset comprising over 225,000 recorded instances of planned trackwork and approximately 32.5 million train passages throughout the year 2017. Multiple logistic and negative binomial regression models showed that train running time delay occurrence is higher in the sections with scheduled trackwork. Trains passing through trackwork are 1.43 times more likely to experience delays compared to trains that do not pass through scheduled trackwork. The likelihood of an opportunity for the train delay recovery passing the section with scheduled trackwork is reduced by 11%. Additionally, the frequency of train delay increase is 16% higher, and delayed recovery is 4% lower in relation to trackwork. With the number of trackwork set to increase over the coming years, these results bring attention to train scheduling and the performance of trackwork.

The study of the interaction of operation and maintenance is very important in preparation for the launch of domestic high-speed traffic.

The stress response of the seagrassZostera nolteiand three commercial clam species to low salinity associated with heavy rainfall

AbstractThe maintenance of stocks of estuarine species strongly depends on the ability of the species to cope with environmental stress. In NW Spain, commercial clam beds, which are usually co-occupied by the seagrass Zostera noltei, are often exposed to reduced salinity caused by intense rainfalls. Our goals were to evaluate the effects of low salinity events on both juvenile clams and Z. noltei, including their interactions. A mesocosm experiment was performed to simulate three salinity decreases (35–35, 25–10, and 20–5), and several indicators of clam and seagrass performance were measured after 3 and 6 days of exposure and again after a recovery period of 4 days. No differences were observed in the non-native clam Ruditapes philippinarum, while oxygen consumption, clearance rate and growth decreased significantly in the native clams R. decussatus and Venerupis corrugata in response to low salinity stress. Zostera noltei indicators did not vary in response to low salinity exposure, except the sucrose content, which decreased. Moreover, the seagrass buffered juvenile clams from salinity fluctuations in the short term, although the interactions were weak. The species-specific sensitivity to low salinity should be a major concern in future management plans for the shellfish beds in the context of climate change.

Mapping and modelling global mobility infrastructure stocks, material flows and their embodied greenhouse gas emissions

Roads and rail-based mobility infrastructures are the basis for mobility services and underpin several Sustainable Development Goals, but also induce material use and greenhouse gas emissions. To date, no stock-flow consistent study has assessed globally accumulated stocks of mobility infrastructures, associated material flows and emissions, and their spatial patterns.We present global findings on material stocks for all roads, rail-based infrastructures, incl. tunnels and bridges, and model associated material flows and their embodied emissions for the year 2021. The stock-flow consistent model combines crowd-sourced Open Street Maps data with archetypical infrastructure designs, material compositions, assumptions on lifetimes and network growth rates, incl. uncertainty ranges. We derive spatially explicit, national-level stock estimates for 180 countries, map them at a resolution of 5 arcminutes, and derive material flows and their embodied emissions at the country-level.We find that 314 [218–403] Gt of materials (41 [28–53] tons/cap) have accumulated in global mobility infrastructure, the majority in roads as aggregates and asphalt. Stocks are unequally distributed between countries, from averages of 23 [16–30] tons/cap in low income countries, to 130 [89–164] tons/cap in high income countries. Spatial inequality of per capita stocks per area differs by orders of magnitude, from 101-104 between rural, suburban, and dense urban areas. We find that 8 [4–16] Gt/year of material flows are due to expansion and maintenance, amounting to 6 [3–10] % of global resource extraction. These translate into 0.36 [0.19–0.69] Gt CO2eq/year, or 1 [0.5–1.9] % of global GHG emissions in 2021.Approximately two-thirds of these flows result from maintenance and replacement of stocks, indicating an important lock-in of resource use due to already existing infrastructure stocks. These findings support the crucial role of improving spatial planning, limiting stock expansion and (sub-)urbanization, to achieve more sustainable resource use and mitigate climate change.

A Set of Products for Remote Control of Rolling Stock Characteristics

A modern specialist in the field of maintenance and repair of rolling stock needs to constantly have access to up-to-date information about the technical condition, equipment and location of serviced units. This article analyzes the existing software products and applications that allow you to plan and manage the processes of repair work and operation. The work is devoted to the creation of products for finding up-to-date information about the technical condition of rolling stock units both on a personal computer and in an online application environment. Programs have the ability to be updated and supported, including bug fixes. The use of the proposed tools will allow a specialist in the field of logistics, maintenance and repair of rolling stock to increase the efficiency of forecasting, organization of transport processes and repair work. The algorithms of operation of each software product are formed in the work. The algorithms are presented in the form of flowcharts. The generated database is presented. Geometric parameters and wheelset numbers, dates of the last maintenance and overhaul, location were added to the presented database in accordance with the number. An array of data with photos of car was also created. The article presents a text written in the Python programming language. This language made it possible to fully implement the algorithm of the products actions. During the testing of the programs, the operation of the main functions was checked, namely, the search for parameters by the composition number. The work solved the problem of displaying photos and videos on the screen at the users request. This function will reduce the time to choose a rolling stock unit for rent and control the quality of repairs. The results of the work of programs in the environment of online applications and on a personal computer are presented in the form of drawings. When creating a software product in an online application environment, the issue of data transfer security (whitelist, password encryption, end-to-end encryption, as well as copy and forwarding protection) was resolved.
