Occurrence and exposure evaluation of bisphenol A and its analogues in indoor and outdoor dust from China

Bisphenol A (BPA) and its analogues have been proved to be harmful to human reproduction, endocrine and nervous system. But information on the occurrence and human exposure to bisphenol compounds (BPs) in dust (especially outdoor dust) is limited. In this study, 14 BPs were determined in 174 indoor dust samples and 202 outdoor dust samples from Chinese mainland, Hong Kong, Macau and Taiwan. BPA, BPS, BPAF, BPF, BPAP and BPE were widely detected with detection frequencies of 98.94 %, 98.67 %, 97.87 %, 95.21 %, 87.23 % and 71.54 %, respectively. The median total concentrations of the most detected six BPs in the dust were in the order of south urban indoors (556 ng/g) > south rural outdoors (438 ng/g) > south urban outdoors (432 ng/g) > south rural outdoors (418 ng/g) > north rural indoors (412 ng/g) > north urban outdoors (341 ng/g) > north urban indoors (311 ng/g) > north rural outdoors (246 ng/g). The amounts of garbage incineration, plastic output and recycled paper may have influence on the BPs levels. Some BPs (BPAF, BPAP, BPF and BPS) in the indoor and outdoor samples were significantly positively correlated. In addition, the BPs in the indoor dust from different indoor micro environments in Chengdu were investigated. BPA (median concentration: 571.2 ng/g) and BPF (median concentration: 114.3 ng/g) were the two primary BPs, accounting for 78.1 % of the median total concentrations of the investigated BPs. High concentration of BPA appeared in printing workshops and offices, while high concentration of BPAP, BPC, BPE and BPF appeared in electronic repair shops. Occupational exposure to BPs deserves attention in the future. ΣBPs exposure risk for children and adults in the urban areas of southern China was the highest. To our knowledge, this is the first report in China to study BPs in outdoor dust sample.

ОБРАБОТКА ОТВЕРСТИЯ ОПОРНОГО РОЛИКА ХОДОВОЙ СИСТЕМЫ ТРАКТОРА ПРОШИВКОЙ

Restoring the surface of the roller treadmill to its nominal value using automatic surfacing technology makes it possible to obtain a significant surfacing layer with a sufficient degree of strength and wear resistance. At the same time, as a result of thermal action, the metal of the roller receives a linear shrinkage, due to which the diameter of the hole for the bearing of the roller axis decreases. In this case, it becomes impossible to install the outer bearing cage. (Research purpose) The research purpose is substantiating the method of processing the seat under the outer bearing cage after surfacing the treadmills of the support roller. (Materials and methods) It was noted that the surfaces of the treadmills of the support rollers wear out quickly as a result of abrasive friction with the track link and the soil. It was clarified that when surfacing in all ways, metal shrinkage occurs and the diameter of the hole for the outer bearing cage decreases. (Results and discussion) It was found that the wear of the treadmills of the support rollers averaged 13.9 millimeters. Restoration of the treadmill surface of the roller to the nominal value, carried out by the method of multilayer automatic surfacing, caused a decrease in the diameter of the roller opening by an average of 0.73 millimeters. We chose from the considered options for calibrating the hole the most preferable from and time-saving one, the firmware processing method. (Conclusions) The appearance of shrinkage of the support roller hole during restoration by automatic surfacing and the method of calibrating the hole using firmware were substantiated. The method provides tension in the coupling of the outer ring of the bearing with the roller within 0.015-0.039 millimeters and surface cleanliness within Ra 1.25-0.63 micrometers. The firmware is simple in design and can be manufactured in a repair shop.

A robust optimization approach to a repair shop network planning

Robust optimization model is a paradigm for decision-making under uncertainty, where parameters are given in the form of uncertainty sets. In this paper, we develop a robust optimization model for a repair shop network planning problem. The linear optimization model involves product of uncertain parameters in the constraints. We formulate its robust counterpart with the help of min-max regret and Lagrangian dual approach, considering the partial information of uncertain parameters is given in the form of ellipsoidal and polyhedral uncertainty sets. We also consider ellipsoidal+polyhedral uncertainty set, which is the intersection of ellipsoidal and polyhedral uncertainty sets. We apply the robust optimization model to a bi-objective multi-plant repair shop network planning problem where multiple pieces of equipment are repaired and overhauled using several resources over a multi-period planning horizon. We consider uncertainty in resource and demand parameters. Numerical examples are presented for illustrating the theoretical results.

Challenges in the digital transaction of an order picking system of an after-sale auto repair shop

This study aimed to enhance the efficiency of the order picking process in Carclasse’s parts warehouse in Braga to achieve this objective, a comprehensive analysis of all warehouse processes was conduct. The initial analysis revealed that approximately 59% of the references in stock were considered obsolete, as they had had zero turnover in the last 5 years. Additionally, a high error rate was identify in the order picking process, with around 6% of references being pick incorrectly. These errors led to discrepancies between the physical stock levels and the system records since some order picking errors went undetected. Moreover, queues were observed among internal customers when requesting material retrieval, which hindered workflow. Based on these findings, improvements were proposed to address the identified issues. One of the key proposals was the implementation of a Barcode scanning system to increase the digitalization of warehouse processes and rectify order picking and stock errors. Additionally, to reduce internal customers’ waiting time, it was suggested to shift the responsibility of part identification for collection to mechanics and increase from 2 to 4 the number of identification stations. It is crucial to highlight that the implementation of the Barcode scanning system can not only reduce order-picking errors but also contributed to the overall optimization of Carclasse’s parts warehouse. With the digitalization of processes, it is expected an enhancement in traceability and inventory accuracy, avoiding discrepancies between physical stock and system records. This can resulted in greater control and reliability of inventory data, providing a solid foundation for operational and strategic decision-making.

Лазерне зміцнення інструментів та деталей обладнання ремонтних майстерень автомобільного транспорту в АПК

The purpose of this work is to study the effect of laser processing on the surface layers of alloys and to study their microstructure and features in order to improve their mechanical properties and increase the production resource of relevant tools and parts of equipment for repair shops of automobile transport in the agricultural sector. The effect of laser processing on the near-surface microstructure of alloys was studied. It is shown which steel will have the maximum hardness as a result of laser hardening among steels 40H13, 30H13 and 20H13. As a result of the change in the chemical composition, the levels of martensitic transformation points in the liquid state zones decrease, and a significant amount of residual austenite (40-60%), characterized by a dispersed structure, remains in them. This has a positive effect on the operational characteristics of irradiated products, especially when exposed to external shock loads. The optimal level of dissolution in R6M5, 9HS and HVG steels of initial carbides to obtain the maximum possible hardness during their laser processing was determined. The value of microhardness and heat resistance of bronze as a result of its laser hardening was investigated. Therefore, the influence of laser processing on the near-surface microstructure of alloys was investigated in order to improve their mechanical properties and increase the resource of production of appropriate tools and parts of automobile transport repair workshops equipment in the agricultural sector. It was determined that the maximum hardness is achieved in the case of hardening steel 40H13, since the carbon content in it is the highest compared to steels 30H13 and 20H13. Also, to obtain the maximum possible hardness during laser processing of R6M5 steel, it is enough to dissolve 30% of the original carbides and 60-70% for 9HS and HVG steels. Treatment of bronze by laser hardening made it possible to achieve values of microhardness up to 700 Hμ50, and heat resistance of the layer up to 350°С. The service life of products made of these laser-hardened alloys is increased by an average of 4-5 times compared to standard heat treatment.

The volume of agricultural products depends on the technical readiness of equipment, repair and maintenance facilities. The emergence of new technologies can change the very process of organizing repairs. (Research purpose) The research purpose is analyzing in historical perspective the mutual relationship of the fleet of machines, the organization and technology of repair and restoration of parts of agricultural machinery. (Materials and methods) Used statistical data, scientific papers of researchers, authors' own observations. We applied the general scientific method, analysis, generalization, synthesis, etc. (Results and discussion) The paper notes the presence during the planned economy of a large fleet of the same type of machines in agriculture, which required constant repair impacts, contributed to the creation of an appropriate repair and maintenance base. It was pointed out that in 1986 184 repair plants were built, 2106 district repair and technical enterprises, including 818 specialized and 1288 general purpose workshops, technical exchange offices, repair shops for worn parts, etc.). The possibility of directive instructions was provided by the mass collection of the same type of parts, which made it possible to apply appropriate technologies on production-mechanized lines, reduce the cost of restoring parts: the organization of repair determined the technology. It has been shown that in a market economy, the equipment nomenclature has decreased, the number of brands has increased, repairs have moved from specialized to agricultural organizations and are mainly reduced to replacing worn-out parts with new ones. At the same time, additive technologies have appeared that do not require reconfiguration of equipment when changing the nomenclature of recoverable parts. (Conclusions) Additive technologies can transform sectoral repairs into intersectoral repairs, which will increase equipment utilization and improve economic performance.
