Abstract. This study highlights the use of biodegradable materials in the medical field for the prevention and repair of fractures, ruptures, and vascular or bone blockages. Various studies have been analyzed, demonstrating that these
degradable biomaterials, when alloyed with different materials such as magnesium, zinc, and iron, have the ability to degrade in a controlled manner within the biological environment, facilitating tissue regeneration without leaving behind residues that could be harmful to the body after the resolution of medical issues. However, research results indicate that these materials have limited applicability due to their restricted degradation rate and the rapid loss of
mechanical properties. To enhance their applicability, reinforcement elements such as biodegradable ceramic materials, nanodiamonds, metallic fibers, and advanced composites are integrated into the biodegradable matrix.
Keywords: biodegradable, biomaterials, metallic, medical.

Abstract. Cooling for tempering as the final operation is of particular importance for obtaining the properties required in operation, such as hardness, mechanical strength and a state of internal stresses corresponding to the demands that the part must withstand in function. Cooling for tempering involves the use of a generally liquid tempering medium such as water, oil, emulsions or solutions from synthetic media. Carboxymethyl cellulose is a substance that results as a secondary product in the manufacture of paper and is used as a cooling medium dissolved in water in percentages of 1.5% to 5%. In the work, the cooling curves of a 2% carboxymethyl cellulose solution in water with initial ambient temperatures of 20℃, 40℃ and 60℃ were analysed.
Keywords: carboxymethyl cellulose, heat transfer coefficient, cooling capacity, cooling speed.

Abstract. Maintenance is defined as a set of activities or tasks used to maintain or restore a system to a state in which it can perform its designated functions. Because the success of all industrial companies is related to their production systems, maintenance plays a crucial role in guaranteeing availability and reliability of production facilities. Outsource maintenance is performed by service providers considering specific knowledge, staff, competencies and technological capabilities. When outsourcing maintenance, the most important part is designing the service contract that establishes the relationship between the beneficiary and the service provider. Based on a literature review, the aim of this paper is to identify and analyse the key aspects that must be specified in the maintenance service contract and the issues regarding the execution of the contract. The contractual relationship must be clearly determined from the beginning as a valid contract concluded represents the law of the parties.
Keywords: maintenance, outsource, contract, rights and obligations.

Abstract. This study analyzes the integration of Phase Change Materials (PCMs) into building exterior walls to develop thermal performance and decrease surface temperatures effectively. PCMs are well-known for their capacity to absorb and release substantial heat during phase transitions and stand in as thermal buffers that stabilize temperature fluctuations within buildings. This investigation aims to introduce the optimum PCM position to reduce exterior surface temperature and heat transfer. Experimental findings emphasize the critical role of PCM layer placement in optimizing effectiveness. In scenario 1-PCM, where the PCM was positioned directly to the heat source, surface temperatures rose from 28.43°C to 75.77°C, a notable improvement over the reference wall’s increase from 31.01°C to 91.00°C. This configuration facilitated efficient heat absorption, resulting in an average surface temperature of 64.33°C, contrasting with 85.94°C in the reference scenario. Scenario 3-PCM, with the PCM layer between a 2 cm outer and 3 cm inner insulation layer, demonstrated minimal indoor temperature increase, rising from 28.58°C to 29.52°C, compared to the reference wall’s rise to 33.11°C. These findings underscore PCM’s potential to enhance energy efficiency and indoor comfort, justifying further research into durability, climatic adaptability, and cost-effectiveness for sustainable building designs.

Abstract. Improving the quality of life for people with special needs is a matter of international concern, necessitating the fashion industry’s commitment to creating equal opportunities for persons with disabilities, preventing discrimination, and enhancing their standard of living as productive members of society. Throughout history, the field of adaptive clothes has shown resilience and progress, evolving from the functional necessities of the early 20th century to today’s innovative technology. The general idea of adaptive clothing is to meet the needs for individuals with various physical limitations by incorporating different features to facilitate easier dressing and undressing, often without assistance. This factor also contributes to empowering individuals to actively participate in social activities. Through raising awareness and cultivating a strong collaboration among designers, researchers, and the disability community, adaptive clothing can become a prominent influence, promoting not just independence but also boosting self-confidence for individuals with disabilities.
However, significant challenges remain. Limited research on user preferences and a lack of public awareness hinders wider adoption of adaptive clothing. Additionally, the cost of these garments can be a barrier for some individuals. Another issue that this field should be focused on is the lack of ergonomic mind that focuses also on comfort. To address these issues, this paper will delve into the current state of adaptive clothing, tracing its progression into a movement for independence and self-expression. The paper examines current design trends, analyzes the benefits for people with special needs, and explore the remaining obstacles that hinder full accessibility.
By addressing these multifaceted challenges, the fashion industry can truly make a difference in the lives of individuals with disabilities. Through collaborative efforts, including research, design innovation, and advocacy, we can create a future where adaptive clothing is not just a niche market but a fundamental aspect of inclusivity and accessibility in fashion.
