This study evaluated the physical, mechanical, and natural durability properties of Lannea acida wood from the savannah ecological zone of Ghana. Three mature trees were sampled from Boli in the Upper West Region, with specimens obtained from the bottom, middle, and top sections of the stem. Physical and mechanical properties were determined in accordance with BS 373:1957, while natural durability was assessed using graveyard tests (EN 252) and laboratory decay tests (ASTM D2017-05). Moisture content increased from 96% at the bottom to 119% at the top, while basic density decreased from 463 to 406 kg/m3. Mechanical properties, including modulus of elasticity, modulus of rupture, compressive strength, shear strength, and Janka hardness, declined progressively along the stem. High mass losses in the field test (71–73%) and laboratory tests (47–59%) resulted in the wood being classified as non-durable (Class IV). Although unsuitable for untreated exterior use, Lannea acida is suitable for non-load-bearing indoor applications, with preservative treatment recommended"},{"@xml:lang":"sl","#text":"Zaradi naraščajočega pritiska na primarne vrste lesa v Gani je nastala potreba po oceni manj znanih avtohtonih vrst kot trajnostnih alternativ. V tej študiji ocenjujemo fizikalne, mehanske in naravne lastnosti trajnosti lesa Lannea acida iz ekološke cone savane v Gani. V Boliju v regiji Zgornji zahod so bila odvzeta tri odrasla drevesa, vzorci so bili pridobljeni iz spodnjega, srednjega in zgornjega dela debla. Fizikalne in mehanske lastnosti so bile določene v skladu s standardom BS 373:1957, medtem ko je bila naravna odpornost ocenjena z uporabo terenskih testov odpornosti v zemlji (EN 252) in laboratorijskih testih razkroja (ASTM D2017-05). Vsebnost vlage se je povečala z 96 % (spodaj) na 119 % (zgoraj), osnovna gostota pa se je zmanjšala s 463 kg/m3 na 406 kg/m3. Mehanske lastnosti, vključno z modulom elastičnosti, modulom lomnosti, tlačno trdnostjo, strižno trdnostjo in trdoto po Janki, so se vzdolž debla postopoma zmanjševale. Zaradi visoke izgube mase pri testih v stiku z zemljo (71–73 %) in laboratorijskih testih (47–59 %) smo les uvrstili med neodporne vrste (razred IV). Čeprav preučevani neobdelani les ni primeren za zunanjo uporabo, je Lannea acida primerna za nenosilne notranje aplikacije, pri čemer se priporoča zaščitna obdelava"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-B0ZLKPR3","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-B0ZLKPR3"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-B0ZLKPR3/702ed094-3127-4830-ad90-d0db162a1ff6/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Gozdarski inštitut Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-B0ZLKPR3/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-B0ZLKPR3"}}}}
