1. Intensive exploration : the application potential of flax fibre/textiles as reinforcement in cementitious compositesWenzhuo Ma, Libo Yan, Bohumil Kasal, 2025, review article Abstract: This review offers an intensive exploration of the compatibility between flax fibre and cementitious materials, including the kinetics of alkaline degradation of flax fibre, and the interaction between fibre leaching/degradation and cement hydration. This paper also focuses on in-depth insights into the formation and ageing mechanisms of the interfacial transition zone between flax fibre and the cementitious matrix, and in turn how the ageing mechanisms affect the mechanical properties and long-term durability of flax fibre/textile reinforced cementitious composites. A systematic literature review reveals that flax fibre offers superior alkaline resistance compared to other lignocellulosic fibres due to its high crystalline cellulose and low lignin content. While the rough surface of flax fibre enhances bonding with the cementitious matrix, its hydrophilic nature can increase porosity at the interfacial transition zone and promote fibre mineralisation due to fibre swelling and shrinkage. Flax fibre reinforced cementitious composites show comparable flexural and compressive properties to those reinforced with other fibres, while flax textile excels in improving ductility over other textiles and steel reinforcements. Additionally, flax fibre degrades at higher temperatures than sisal and jute fibres. Despite growing interest in flax fibre/textile reinforcement for cementitious composites, key gaps remain in understanding the kinetic mineralisation process of flax fibre, the effects of the alkaline environment and hydration heat on its degradation, and the impact of its alkaline degradation products on cement hydration. Further research is needed to develop direct pull-out testing methods, explore the thermal/fire behaviour of composite phases encompassing the polymeric coating, and create a sustainability framework that considers ecological impacts, recyclability, and waste management for natural fibre reinforced cementitious composites.

10. The dynamic internationalization model of Slovenian born global SMESIna Lejko, Štefan Bojnec, 2013, original scientific article Abstract: Small and medium sized enterprises (smes) are important business actors in the Slovenian, as well as European economy. In addition to the current global market conditions, reflecting a severe economic downturn, the smes in Slovenia and other transition economies operate under additional extensive external pressures, arising from the opening of their domestic markets. Under such conditions, companies, including smes, perceive internationalization as an inevitable, or even urgent step in the process of their business operations. However, companies pursue different paths in their internationalization efforts, one of them being a rapid internationalization strategy, denoted as the Born Global concept. In the paper, we explore the internationalization process of Slovenian Born Global smes. We employ an exploratory qualitative case study analysis of selected Slovenian smes in order to grasp the key characteristics of their internationalization process. On the basis of the latter we construct a dynamic internationalization model that might be used as a conceptual framework for empirical research of dynamic smes market behavior in Slovenia and other transition countries.
