Item type:Publication, Influence of the Corner Joints of the Window Frame and Sash on the Final Quality of the Window(2025-12-04); Mihajlovski, NikolaThe quality of a product is a characteristic that demonstrates how well it meets the needs for which it is intended. Given that, a window purpose is to provide light and desired ventilation to a room, while at the same time protecting the building from external influences such as air permeability, water permeability and wind resistance, we prove that it is of high quality the more it provides us with these conditions. A window as a product is a complex composition of different materials and parts. The different parts of a window include the basic structural elements, filling elements, fitting, and additional accessories. The basic structural elements of a window are the supporting frame and the window sash. The corner joints of these elements will be the target of research, in terms of how the strength of the joint of the corner segments of windows made of wooden frame, PVC frame or aluminium frame can affect the window's resistance to air permeability, water permeability and wind resistance. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, STRENGTH OF THE CORNER JOINTS OF THE WINDOW FRAME(2025-09-17); Mihajlovski, NikolaThe window as a product used in construction aims to provide natural light and the possibility for ventilation in the building where it is placed but at the same time to protect the room from external influences such as wind and rain and to prevent uncontrolled cooling or heating of the building in which it is built-in. Given the purpose, a quality window is one that protects against air permeability, water permeability and provide wind resistance. The window is a complex product that is composed of different parts that can be made of different materials. This research is focused on the area of frame joining and joint strength. This research will cover windows made from the same PVC profile but manufactured in different production facilities. The windows will be measured for air permeability, water permeability and wind resistance, and corner samples will be taken after wards. The samples are prepared according to the standard EN 514:2018 Plastics - Poly(vinyl chloride) (PVC) based profiles - Determination of the strength of welded corners and T-joints. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Wood waste in the sawmill industry of wood processing(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2023-09); Sawmill processing produces a certain amount of waste, as a result of processing sawlogs into sawn lumber. Waste occurs in the form of fine and coarse waste. Fine and coarse waste are generated on the primary milling machine (band saw) and on the circular saws for transversal and longitudinal lumber cutting. In addition to fine and coarse waste, sawdust also occurs as waste, but due to its specificity, it is not quantified. This paper presents results obtained from several years of research, conducted in five sawmill capacities. The researched capacities were at the territory of the Republic of North Macedonia. The data was gathered under manufacturing conditions. The wood species covered in the paper are beech (Fagus sylvatica L.), pine (Pinus sylvesteris, Pinus nigra), oak (Quercus sessiliflora), aspen (Populus tremula L.) and fir/spruce (Abies alba/Picea excelsa). The results indicate that beech has the highest percentage of total waste, and fir/spruce has the lowest percentage of total waste. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Determination of the heat energy for hydrothermal treatment of ashwood (Fraxinus excelsior) by log soaking(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2023-09); The treatment of logs by soaking is a complex technological and thermal procedure, in which logs and prisms are used as raw material for the production of peeled and sliced veneers. Such treatment of logs is carried out in pools or pits constructed in the ground. By log soaking two significant changes to the wood are achieved, its coloring and the inevitable plastification of the wood fibers. During this procedure, the time required for air drying is significantly reduced. The soaking medium is fresh water or previously used water at an elevated temperature. This soaking treatment is particularly suitable for logs for the production of peeled and sliced veneer, from which resin must be removed. Soaking is also used when treating wood species that are sensitive to steaming. This paper provides an analysis of the thermal energy required for hydrothermal treatment by log soaking of ashwood (Fraxinus excelsior). The logs were intended for the production of peeled veneer. The log treatment was done in a reinforced concrete pool built in the ground. The total amount of heat for log soaking (Q) consists of effective heat (Qpv) and heat loss (Qzv). The procedure was conducted by the strong treatment mode, with a temperature interval in the range of 70 to 90 °C. The treated logs had a minimum mean diameter of 35,0 cm and a minimum length of 1,8 m. Log soaking was used as a method for defrosting of the logs, due to their low initial temperature, which was– 15 °C. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Analysis of heat and steam consumption during artificial convective drying of oak sawn timber of different thickness(Faculty of Design and Technologies of Furniture and Interior - Skopje, 2023-09); ; ; ; In the paper, the consumption of heat and steam of oak sawn timber with a thickness of 25,0 and 50,0 (mm) are analyzed under conditions of classic convective drying. The drying mode is compiled on the basis of data on the temperature of the drying agent (air), the relative humidity of the air and the speed of air movement in accordance with the current value of moisture in the wood. The heat consumption is analyzed in all stages of the drying cycle such as heating the wood, active drying of the wood, equalization of the average moisture in the wood and conditioning, i.e. equalization of the moisture in the cross-section within ± 2.0 (%). The moisture content of sawn timber at the beginning of drying is about 55,0 (%) and at the end of drying is 10,0 (%). The sawn timber are intended for the production of solid wood panels. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Comparison of log taper in different wood species(Department of Wood Technology, Faculty of Forestry and Wood Technology, University of Zagreb, Croatia, 2023-12); ; The rational yield of the sawlogs is one of the key factor for the prosperity of the sawmill capacity. One of the factors that significantly influence the maximum quantitative yield of sawlogs is the diameter taper. The diameter taper is an inevitable sawlogs occurrence and it is determined by the geometry of the logs. The diameter taper is defined as the difference between the diameters of the two ends of the log, alongside its length. Great differences between these two diameters adversely affect the percentage of maximum quantitative yield. This parametar plays a fundamental role in the classification of logs into quality classes. The aim of the paper is to compare the diameter taper in different wood species. Wood species of interest are: beech (Fagus sylvatica L.), pine (Pinus sylvestris, Pinus nigra), oak (Quercus sessiliflora), and fir/spruce (Abies alba/Picea excelsa). Log length is of important influence in the value of log taper. Therefore, the analysis for the different wood species will also present different groups of lengths, in order to determine the different values for the log taper. The selection of wood species is for the purpose of comparison of the taper values in deciduous and coniferous wood species.
