| Abstract | In this study, test samples of juvenile and mature black pine wood were treated for 3 h at temperatures of 140, 170, and 200 °C. Mass loss, density, equilibrium moisture content (EMC), modulus of rupture (MOR), modulus of elasticity, and impact bending strength (IB) of the separate samples were determined. The purpose of the tests was to determine how heat treatment at the three temperatures influenced the properties of the juvenile and mature wood. The results showed that heat treatment had greater effects on mass loss, EMC, and density of juvenile wood than of mature wood. The results also showed that heat treatment had lesser effects on the MOR, modulus of elasticity, and IB of juvenile wood than of mature wood. The results clearly indicated that heat treatment had different effects on the properties of juvenile and mature black pine wood.In dieser Studie wurden Prüfkörper aus juvenilem und adultem Schwarzkiefernholz bei Temperaturen von 140, 170 und 200 °C für eine Dauer von 3 Stunden behandelt und der Masseverlust, die Dichte, die Gleichgewichtsfeuchte, die Biegefestigkeit, der Elastizitätsmodul und die Schlagbiegefestigkeit wurden bestimmt. Ziel dieser Studie war es, zu ermitteln, inwieweit eine Wärmebehandlung bei den drei Temperaturen die Eigenschaften von juvenilem und adultem Holz beeinflusst. Die Ergebnisse zeigten, dass sich die Wärmebehandlung auf den Masseverlust, die Gleichgewichtsfeuchte und die Dichte von juvenilem Holz stärker auswirkt als bei adultem Holz, wohingegen die Biegefestigkeit, der Elastizitätsmodul und die Schlagbiegefestigkeit bei juvenilem Holz weniger stark beeinflusst wurde als bei adultem Holz. Die Ergebnisse zeigen deutlich, dass sich eine Wärmebehandlung auf die Eigenschaften von juvenilem und adultem Schwarzkiefernholz unterschiedlich auswirkt. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
