“…This observation is confirmed by a number of studies (Kuroda et al, 2022;Park et al, 2022). Resin from the top layers runs down to the butt end of the trunk, which explains a sharp increase in the density of this area right after the fire, before wood is affected by a fungal disease (Kiseleva et al, 2020).…”

Introduction: Today, the need for the neutralization of the environmental, economic, social, and other consequences of natural emergencies is becoming more and more urgent. One of such devastating disasters is forest fires, which are currently very widespread in the world. In most cases, after a fire, we are left with a forest that was partially exposed to fire. A burnt tree loses its immunity. As a result, an outbreak of various subcortical insect species, which infect healthy trees as well, occurs in these territories. Such a forest is subjected to sanitary cutting. Purpose of the study: We aimed to determine the residual mechanical properties of raw wood to be used as a structural material. Methods: In the course of the study, we used destructive and non-destructive testing methods in respect of the mechanical properties of the material. Results: It was established that changes in the microstructure of wood correlate with its strength properties. The maximum decrease in the strength properties of wood was observed at the top end of the tree and amounted to 22.7% as compared to the reference wood. The minimum decrease in the strength properties of post-fire wood was observed in the butt end of the tree and amounted up to 15.0%. In the middle part, a decrease in the strength properties of wood was up to 24.0%.

Introduction: Heritage conservation attracts wide attention worldwide. Jordan has many heritage buildings that were preserved, rehabilitated, and adapted to new functions. However, these conservation efforts could not solve the energy consumption problem or maintain the economic and financial balance, thus reducing building efficiency, slowing down the conservation activity, and forcing us to consider new solutions, especially since Jordan has limited energy sources. Integrating smart technologies in historical buildings is widely effective in achieving the sustainability of their historical, symbolic architectural values. Purpose of the study: We aimed to explore the potential integration of smart technologies in cultural and heritage buildings. Methods: We suggested an alternative solution -adopting the smart building concept in the Abu Jaber Museum in Al-Salt (which recently got on the UNESCO World Heritage List since it has more than 1000 heritage buildings), using an automated lighting control system. Approach: We deployed the qualitative method and case study approach to investigate the potential of adopting the smart building concept in the historical building in Al-Salt, Jordan. The study sheds light on the possibilities of utilizing smart technologies in historical buildings in Al-Salt.The findings indicate that smart technologies can offer great opportunity in preserving the architectural heritage and raising the efficiency of heritage buildings. Novelty: The study provides a framework based mainly on automated lighting systems in historical buildings. For the first time, the focus was on historical buildings in Jordan and their performance.

An individual process of staining of each trunk occurs as a result of the long-term presence of wood in the river soil without oxygen access. It consists in changing the structure and chemical composition of the wood. There are industrial reserves of this wood on the territory of the Russian Federation, in the floodplains of a number of rivers. One of the most important tasks at the extraction stage is the primary individual quality assessment of the trunk. One of the most effective diagnostic indicators for assessing wood quality can be the number of annual layers in one centimeter. This indicator correlates well with wood density. The purpose of the research is to establish the influence of the macrostructure of natural wood and stained oak wood, changes in the microstructure on its density. It was found that the density of stained oak wood, depending on the number of annual layers in 1 cm, is about 10% higher than that of natural wood, all other things being equal. The magnitude and nature of the decrease in density along the radius of the trunk is the same as in natural wood. It is about 20%. The performed studies will allow making an express analysis of the quality of each stained wood trunk at the stage of making a decision on the behavior of its extraction. This will significantly reduce the cost of logging and primary processing of stained oak wood
