1. Wood modification using Fast Pyrolysis Bio-Oil (FPBO) : formulation development, characterization, and evaluation of wood performanceAnna Malgorzata Sandak, Faksawat Poohphajai, Amina Selmanović, Rene Alexander Herrera Diaz, Jakub Grzybek, Kelly Peeters, Sasikala Perumal, Edit Földvári-Nagy, Lei Han, Richard Acquah, Jakub Michal Sandak, 2026, original scientific article Abstract: This study presents a wood modification process using Fast Pyrolysis Bio-Oil (FPBO) as a fully biobased alternative to conventional, fossil-based and potentially toxic preservatives such as copper salts, organic biocides, and creosote. Standard FPBO was used in the devel- opment of 10 formulations, which were systematically characterized in terms of pot life, viscosity evolution, density, and pH. Radiata pine samples were subsequently impregnated using a bench-scale reactor, with specimens prepared in multiple geometries to assess treat- ment performance across different dimensions. The modified wood was comprehensively characterized with respect to moisture uptake, dimensional stability, density, mechanical strength, fixation efficiency, biological durability, and VOC emissions. Additional screening focused on properties relevant to outdoor applications, including aesthetic appearance and colour uniformity after UV exposure. The results enabled the identification of three top-performing formulations, treatments H, A, and E, which exhibited the most favourable balance between durability, environmental performance, and structural integrity. Overall, the findings demonstrate the strong potential of FPBO-based impregnation as a sustainable, multifunctional, and high-performance alternative for advanced wood protection systems.

9. Accounting treatment of goodwill in IFRS and US GAAPMateja Jerman, Massimo Manzin, 2008, original scientific article Abstract: The article presents an overview of the new accounting treatment of goodwill regarding International Financial Reporting Standards and American Generally Accepted Accounting Principles. Goodwill acquired through a business combination is no longer amortized but tested for impairment. Despite the fact that the objective of the new International Financial Accounting Standard has been to move towards international convergence; significant differences between standards still exist. The article presents the main changes of the regulation in the last years and the key differences between the two accounting treatments. In spite of the new accounting approach there are still lots of discussions, which indicate that the field is still not properly regulated. Finally, the article offers possible directions for future research and reporting practice.

10. Institutional work in total institutions and the perspective of the persons that have lived in residential treatment institutionsMitja Krajnčan, Boštjan Bajželj, 2015, professional article Abstract: Institutional work includes all kinds of psychosocial assistance that offers, to people that need them, living environments and immediate environments adapted to their age, problems, disorders, and state. The diversity and dilemmas of institutional work represent the central theoretical discourse that the authors are researching in the explanations of the total institution, the exact answers regarding the help the youth that involuntarily find themselves in such institutions receive. The continued development of the discourse logically proceeds into deinstitutionalisation. Semi-structured interviews of adults that have spent their youth in such institutions represent the empirical part of the research. Extreme psychosocial pressures make the youth deviate away from goal orientation and the purpose of the institutions% operations. So, additionally, the authors have gathered a collection of good and bad experiences to bring attention to the many imperfections that should not be self-evident. The key problems that people that have stayed in such institutions a decade ago would like to give light to are the non-existence of logic and specific learning and practical competences that would benefit them in the life outside of the institution. They also stressed the lack of using the quality relations that had been established in the institution as support in post-treatment.
