Medical device management reform, United Republic of Tanzania.

Health-care technology is central to boosting the productivity and quality of health-care systems. In many sub-Saharan African countries, however, medical device management systems are weak or absent. The aim of this article is to illustrate, using a case study, how policy reforms can help ensure policy on health-care technology is translated into everyday practice and how an integrated systems approach can enhance the operation of medical device management. Between 2011 and 2023, a plan to improve medical device management systems in the United Republic of Tanzania was developed and implemented through Swiss-Tanzanian cooperation within the Health Promotion and System Strengthening Project. The availability of biomedical engineers was increased through new training courses and the creation of permanent positions in government. Moreover, additional district and regional maintenance and repair workshops were built, and a National Centre for Calibration and Training was established to ensure the correct functioning of medical devices. The introduction of an electronic medical device management system provided health facilities and the health ministry with data on the operational status of medical devices and the need for repairs and spare parts. Every level of government was encouraged to allocate more human and financial resources to medical device management. Following this decade-long effort, the percentage of functioning equipment increased substantially, and costs were reduced by repairing rather than replacing equipment. The project also demonstrated the value of an integrated, system-strengthening approach that considered personnel, maintenance and repair facilities, documentation and management, and government policy and budgeting.

E-waste management from electronic repair workshops: Societal implications and environmental consequences

Improper disposal of faulty electronic devices can result in pollution, health hazards, social inequity, and legal issues. This study explores the perceptions and practices of electronic waste management among electronic repair technicians in Ho Municipality, Ghana, with a focus on the significant societal and environmental impacts of e-waste generated in electronic service workshops. A survey using both random and purposive sampling of 150 electronic repairers in Ho Municipality found limited awareness of the negative effects, toxic components, environmental risks, and proper handling and disposal procedures associated with e-waste. Notably, only 31 % of participants were aware of the environmental risks, while 69 % were not. "Experience" emerged as a significant predictor of awareness regarding e-waste health risks. Only 22 % were knowledgeable about the hazardous substances in e-waste, indicating a low level of awareness of its risks and opportunities for reducing them. These findings highlight the need for collaboration among stakeholders to implement sustainable e-waste management practices in alignment with the Sustainable Development Goals (SDGs).

Which is more effective? Porcine tendon or 3D- printed flexor tendon? A study of model realism and educational utility in a flexor tendon repair workshop

IntroductionAnimal models in orthopaedic surgical training have raised concerns about ethics and availability, prompting the search for non-animal alternatives. The 3D-printed silicone tendon model has emerged as a potential alternative due to its hygiene and reusability. This study aimed to compare the effectiveness of the two models for flexor tendon repair training. Materials and methodsA survey involved 25 postgraduate trainees with no prior experience in flexor tendon repair. Porcine tendon models and 3D-printed models were used, with participants evaluating accuracy, understanding of pulley systems, joint flexion, tissue feel, and model realism. Repairs were evaluated by experienced surgeons, and participants completed a survey. ResultsBoth models demonstrated satisfactory accuracy and realistic joint flexion. The porcine model scored higher in anatomical accuracy, while the 3D-printed model excelled in understanding pulley systems. The porcine model provided realistic tissue feel, while the 3D-printed model facilitated anatomy teaching. No significant difference was found in educational utility. The 3D-model was perceived as hygienic and odourless, whereas the porcine model offered better tendon handling. The 3D-model improved visualization of suture placement. Both models were equally accepted and recommended for training. ConclusionThe 3D-printed silicone tendon model is a cost-effective and reproducible alternative to porcine models in flexor tendon repair training. Although the 3D-printed model has limitations in mimicking human tendons, it was equally effective in teaching suturing techniques and improving repair skills. Combining the porcine model and 3D-printed model provides a comprehensive approach to flexor tendon repair training, addressing the limitations of each model and enhancing the educational experience.

Molecular identification of biosurfactant-producing bacteria obtained from oil-polluted soil samples in Abakaliki, Ebonyi State, Nigeria

Several human activities have led to environmental pollution with crude oil and other related hydrocarbons. There are various technologies of remediating oil-polluted environments, but the use of biological agents such as biosurfactants are widely practiced, and are generally considered as safe and eco-friendly. This study aimed at isolating and identifying biosurfactant-producing bacteria obtained from oil polluted soil samples in Abakaliki, Ebonyi State, Nigeria using molecular techniques. Six waste oil-contaminated soil samples were collected from mechanic and generator repair workshops, and were analyzed using standard microbiological methods. Nine bacterial isolates were obtained from the waste oil-contaminated soil samples, and were suspected to be Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. Molecular identification of the biosurfactant-producing isolates was also carried out using PCR and the genes responsible for biosurfactant production targeted. Oil spreading technique was used to detect the oil displacement activity (ODA) of the isolates. The emulsification index (E24) was calculated and the ability of the extracted biosurfactant to emulsify the hydrocarbons was determined. Pseudomonas aeruginosa had the highest ODA of 28.1 cm while Staphylococcus aureus had the least ODA of 5 cm. Pseudomonas aeruginosa showed E24 of 70.1%, Bacillus subtilis 57.1% while S. aureus showed 32.5%. Hence, Pseudomonas and Bacillus species have good potentials for biosurfactant production, and can be harnessed and utilized in the cleanup of oil polluted soil.

Genome-Based Classification of Pedobacter albus sp. nov. and Pedobacter flavus sp. nov. Isolated from Soil

Two rod-shaped, non-spore-forming, Gram-negative bacteria, strain KR3-3T isolated from fresh soil in Korea and strain VNH31T obtained from soil samples from motorbike repair workshop floors in Vietnam, were identified. Phylogenetic analysis utilizing 16S rRNA gene sequences revealed their affiliation with the family Sphingobacteriaceae and their relation to the genus Pedobacter, exhibiting 16S rRNA gene sequence similarities lower than 98.00% with all known species within the genus Pedobacter. Growth of VNH31T and KR3-3T was impeded by NaCl concentrations exceeding >0.5% and 1.5%, respectively, while they both thrived optimally at temperatures ranging between 25 and 30 °C. Notably, neither strain reduced nitrate to nitrite nor produced indole. Negative results were observed for the acidification of D-glucose and hydrolysis of urea, gelatin, casein, and starch. VNH31T exhibited growth on β-galactosidase, sodium acetate, L-serine, and L-proline, whereas KR 3-3T demonstrated growth on D-glucose, D-mannose, D-maltose, N-acetyl-glucosamine, sucrose, sodium acetate, L-serine, 4-Hydroxybenzoic acid, and L-proline. Core genome-based phylogenetic analysis revealed that the two isolates formed distinct clusters within the genus Pedobacter. The DNA G+C contents of KR3-3T and VNH31T were determined to be 44.12 mol% and 32.96 mol%, respectively. The average nucleotide identity and in silico DNA-DNA hybridization relatedness values (67.19–74.19% and 17.6–23.6%, respectively) between the Pedobacter isolates and the closely related type strains fell below the threshold values utilized for species delineation. Following comprehensive genomic, chemotaxonomic, phenotypic, and phylogenetic analyses, the isolated strains are proposed as two novel species within the genus Pedobacter, named Pedobacter albus sp. nov. (type strain KR3-3T = KACC 23486T = NBRC 116682T) and Pedobacter flavus sp. nov. (type strain VNH31T = KACC 23297T = CCTCC AB 2023109T).

Anthropogenic determination and risk assessment of total petroleum hydrocarbons of ground water within Orji auto repair workshops, Owerri, Imo State, Nigeria.

The research determined the anthropogenic source and risk evaluation of total petroleum hydrocarbons of some ground water sources within Orji auto repair workshops, Owerri, Imo State, Nigeria. The concentrations of total petroleum hydrocarbons in different groundwater samples within this vicinity were determined by selecting samples from five sampling locations using the liquid-liquid extraction process and gas chromatography fitted with a flame ionization detector. The concentrations of TPHs were determined with C15 (Pentadecane) and C30 (Triaconate) having the highest total concentrations in all sample locations of 29.67μg/mL and 23.17 μg/mL respectively while C13 (Tridecane) had the lowest combined concentration of 0.13 μg/mL with the presence of both low molecular weight and high molecular weight TPHs, an indication that the water samples had significant levels of carcinogens. Diagnostic ratio and correlation analyses of the samples analyzed showed contamination of the groundwater sources were both of petrogenic and pyrogenic sources. TPHs concentrations found in this study also revealed considerable amount of pollution with respect to contamination factors, pollution load index and degree of contamination. Elevated hazard index was equally observed for adults and children indicating a potential harm to the health of children and adults suggesting a higher risk of cancer from interaction with the polluted water. These results indicate that in remediation actions needs to be carried out before consumption to avoid fatal long term heath consequences.

USING INDUCTION HARDENING TO STRENGTHEN CAR PARTS

The war waged by the Russian state against independent Ukraine posed new difficult tasks for society in the production and repair of damaged military equipment. In the conditions of a shortage of military equipment, carrying out repairs becomes a task that must be performed quickly and efficiently in order to replenish the armed forces of the state. In such difficult conditions, methods of high-speed processing should be used, including methods of surface strengthening of machine parts. The work is devoted to the improvement of technological processes of restoration and strengthening of parts of automobile and military equipment at repair factories under conditions of martial law. The efficiency of auto repair production is determined by the number of parts that are restored and continue to perform their functions with even better indicators than before restoration.Most parts have a residual resource and can be reused as a result of carrying out a relatively small amount of work on their restoration. The main methods of surface strengthening of machine parts are chemical and thermal treatment (cementation, nitriding, nitrocementation), surface plastic deformation, application of electrolytic coatings and surface hardening - laser and induction using high frequency current. The processes of chemical and thermal treatment are long-term and are not relevant in repair production in wartime. Modern mobile repair workshops prefer equipment and tools that are not metal-intensive and are able to perform technological processes in a short period of time. The most expedient at present is the introduction of technological processes using installations that produce high-frequency current and processes based on it.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45. The choice of the type of inductor and its calculation are based on the relevant conditions described in the work.In the work, the authors conducted research and developed an inductor for hardening the rocker arm made of steel 45. The choice of the type of inductor and its calculation are based on the relevant conditions described in the work.

Cottage industry as a source of high exposure to lead: A biomonitoring study among people involved in manufacturing cookware from scrap metal.

In low-income countries, a widespread but poorly studied type of cottage industry consists of melting scrap metal for making cookware. We assessed the exposure to lead (Pb) among artisanal workers, and their families, involved in manufacturing cookware from scrap metal. In a cross-sectional survey, we compared artisanal cookware manufacturing foundries with carpentry workshops (negative controls) and car battery repair workshops (positive controls), all located in residential areas, in Lubumbashi (DR Congo). We collected surface dust in the workspaces, and blood and urine samples among workers, as well as residents living in the cookware workshops. Trace elements were quantified in the samples by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). In surface dust, median Pb concentrations were higher in cookware foundries (347 mg/kg) than in carpentries (234 mg/kg) but lower than in battery repair workshops (22,000 mg/kg). In workers making the cookware (n = 24), geometric mean (GM) Pb blood cencentration was 118 μg/L [interquartile range (IQR) 78.4–204], i.e. nearly twice as high as among carpenters [60.2 μg/L (44.4–84.7), n = 33], and half the concentration of battery repair workers [255 μg/L (197–362), n = 23]. Resident children from the cookware foundries, had higher urinary Pb [6.2 μg/g creatinine (2.3–19.3), n = 6] than adults [2.3 (2.2–2.5), n = 3]. Our investigation confirms the high Pb hazard linked to car battery repair and reveals a high exposure to Pb among artisanal cookware manufacturers and their families, especially children, in residential areas of a city in a low-income country.

Levels of polycyclic aromatic hydrocarbon in the soil around typical automobile repair workshops in Nigeria.

This study determined the levels of polycyclic aromatic hydrocarbons (PAHs) in the soil around typical automobile repair workshops in Nigeria. Risk assessment associated with human contact with the soil was carried out using hazard quotient (HQ) and incremental life cancer risk (ILCR) from human unconscious ingestion and dermal contact with the soil. Soil samples were obtained at different automobile workshops in Ado-Ekiti, Western Nigeria. The PAHS in the samples were extracted using dichloromethane and extracts were cleaned up using silica-alumina gel open column chromatography. Analysis of PAHs in the soil was done using a gas chromatograph coupled to a mass selective detector operated on electron ionization mode. The results showed the mean PAHs concentration at the sampling locations ranged from 5.58 - 6.4 μg/g and the mean ∑ carcinogenic PAHs was 58.4 μg/g, equivalent to 59.39 % of total PAHs observed. The mean Toxicity equivalence (TEQs) ranged from 0.02 - 6.680 μg/g. Benzo (a) pyrene and dibenzo(a,h)anthracene have the highest toxicity equivalent. The total ILCRs from accidental ingestion and dermal contact in adults were 1 ×10^(-3) and 9.8 ×10^(-5), for adults and children respectively; both are higher than the permissible limit stipulated by the World Health Organization.The HQs obtained are several folds higher than 1. This implies high carcinogenic and non-carcinogenic risks for children and adults. The study revealed the levels of PAHs and also revealed the risks associated with human contact with the soil around automobile repair workshops.

ИНТЕНСИВНЫЕ ТЕХНОЛОГИИ ФОРМИРОВАНИЯ ВОЕННО-ИНЖЕНЕРНЫХ И ВОЕННО-УПРАВЛЕНЧЕСКИХ КОМПЕТЕНЦИЙ У СТУДЕНТОВ – БУДУЩИХ ОФИЦЕРОВ РЕЗЕРВА

The article discusses the results of scientific research on the development and use of high-intensity educational technologies - project-based and game-based learning in the system of professional training for future reserve officers of the Armed Forces of the Russian Federation. The article demonstrates the interconnection and continuity between the study of disciplines at specialized departments and the study of military training disciplines by students of the military training center at Samara State Technical University. The aim and outcome of their education, when studying military engineering and military management disciplines, is to develop a set of military engineering and military management professional competencies. The final stage of students' education is a training camp, during which they consolidate a large amount of material they have learned and prepare for the final military training assessment. However, a socio-didactic contradiction arises: on the one hand, there is a need to review a large volume of educational material, but on the other hand, there is limited time available. Therefore, the authors turned to the use of well-known intensive teaching technologies - projectbased and game-based learning - in global and domestic pedagogy. Project-based learning technology intensifies students' independent creative project activities and is multifunctional. It includes a mandatory pragmatic component, the completion of which stimulates students' interest in solving specific problems, acquiring knowledge freely, and applying it in practice. Its application is considered on the example of practical classes on automotive equipment restoration. Game-based educational technology in the format of business and role-playing games is discussed using the example of a practical class on "Military Repair Workshops".

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.

IMPROVING THE ORGANIZATION OF CENTRALIZED RESTORATION OF AGRICULTURAL EQUIPMENT PARTS

Effective use of machines largely depends on timely and high-quality maintenance and repair. Due to the increase in the volume of restoration of units and aggregates at specialized enterprises, an opportunity was created in the workshops of farms and collective farms to more widely apply the aggregate method of restoration and repair. Improving the organization of centralized restoration of damaged parts makes it possible to restore tens of millions hryvnas worth of parts in a year. The organization of centralized delivery of material and technical means to farms is applied using the services of equipping farms with the necessary equipment in assembled, adjusted and run-in form. Increasing the level of concentration of repair production, deepening its specialization will allow to significantly improve the quality of repair, to bring the resource of repaired machines, tractors, combines and aggregates up to 80%. Before repairing driven discs of clutches of tractors, cars, combines, to replace friction linings, it is necessary to carry out operations of drilling, riveting and knocking off old linings. These operations require a lot of labor and the use of additional tools, which leads to significant capital investments. The paper proposes a device for cutting the fastenings of the friction linings of the driven clutch discs. Taking into account the conditions of agricultural enterprises, which have repair workshops, and the presence of vertical boring and milling machines, it is proposed to organize their use for the operation of removing worn friction linings. For riveting of friction linings of driven clutch discs, the development of a hydraulic stand is proposed, which can be made from standard units in the workshops of agricultural enterprises. Using this stand will make it possible to increase labor productivity when performing this operation and reduce its time.
