Summary: This article presents the research and standardization of the load-bearing behavior of nails in wood construction, focusing on the development of the structural use of nails in the early 20th century. It showcases the systematic studies and regulations that have made nails an important fastener in timber structures. Through a timeline, tables, and graphics, the connections and changes between research and standardization are highlighted, emphasizing that much of the current knowledge can be attributed to the foundational research of the 1930s.

Summary: This study focuses on investigating the rheological properties of rubber compounds by using biowaste wood flour as a replacement for plasticizers. The compatibility of wood flour with the rubber matrix will be confirmed through scanning electron microscopy. If successful, the substitution of plasticizers with wood flour is expected to significantly reduce production costs and environmental impact.

Summary: In this paper, the grain growth behaviors of niobium-free, 0.021 wt. % niobium microalloyed, and 0.024 wt. % niobium-0.0022 wt. % boron microalloyed 20MnCr5 steels were investigated. It was found that the addition of niobium reduces the prior austenite grain size, while the addition of boron causes grain coarsening. Thermodynamic and kinetic calculations were performed to explain the mechanism behind these grain growth behaviors, which is attributed to the difference in solution temperatures of the precipitates.

Summary: The influence of composition, specifically manganese and nitrogen content, on the microstructure and corrosion resistance property of newly developed stainless steel has been studied. The addition of manganese and nitrogen as a substitute for nickel favors the austenite microstructure and improves the mechanical properties. Electrochemical tests show remarkable improvement in corrosion resistance with manganese stainless steel exhibiting passivity behavior similar to commercial stainless steel.

Summary: This paper discusses the importance of flexibility in production systems for Industry 4.0. It proposes the Capability and Skill Reuse (CSR) framework to adapt traditional reuse approaches, such as VDI 3695, for C&S models. The framework aims to improve engineering flexibility in the production system life-cycle and highlights open research issues.

Summary: This study investigates the effects of iron (iii) oxide and multi-walled carbon nanotubes on the microstructure and hardness of aluminum matrix composites. It shows that aluminum-iron (iii) oxide composites have a better microstructure and higher hardness value compared to aluminum-iron (iii) oxide-carbon nanotubes composites, which exhibit a defective microstructure and lower hardness values.

Summary: This study investigates the effects of niobium content on the microstructures and mechanical properties of W-Mo-V high-speed steel. The results show that the addition of niobium improves the microstructure, mechanical properties, wear resistance, and ductility of the samples, especially at 2 wt % niobium content.

Summary: Using data from the IQB country comparisons and educational trends, this article examines the differences in educational participation and reading competencies between students from immigrant and non-immigrant families in East Germany compared to West Germany. The study finds that there are significantly fewer or no ethnic educational disparities in East Germany, and this is mainly due to lower inequality in social origin and the social composition of school classes.

Summary: During the COVID-19 pandemic, strict infection control measures in long-term residential care in Germany burdened staff and isolated residents socially, which are considered risk factors for violence. Preventive strategies for violence in nursing homes need to be better established and adapted to pandemic conditions.

Summary: The corrosion behavior of structural carbon steels grade SS400 coated with copper and zinc exposed to soil sample from the central part of Thailand was studied using weight loss analyses and electrochemical methods. The effects of coating material, thickness, and process on the corrosion resistance of carbon steel in a soil environment were reported and discussed, showing their significant impact on the corrosion behavior.

Summary: This study proposes a novel photodynamic therapy that utilizes hyaluronidase and metformin to enhance therapeutic efficacy. By improving the stiffness and permeability of dissolving microneedles, the photosensitizer can penetrate deep lesions more effectively. Meanwhile, metformin can intervene in cellular respiration and autophagy process, amplifying the effectiveness of photodynamic therapy.
