| Popis: | Pred drugo svetovno vojno so v okolici Golega vrha postavili obsežno podzemno utrdbo. Še od časa izgradnje je v utrdbi ostalo nekaj lesa, dodatno so pred leti namestili nekaj lesenih razstavnih predmetov. Na lesu je bilo nekaj let po odprtju opaziti obsežen glivni razkroj. V utrdbi smo namestili senzor za spremljanje relativne zračne vlažnosti in temperature, izolirali nekaj vzorcev lesa in jih preiskali z rentgensko fluorescenčno spektroskopijo in lasersko konfokalno vrstično mikroskopijo. Analiza je potrdila visoko vlažnost lesa in prisotnost gliv razkrojevalk na vseh lesenih eksponatih z izjemo lesenih zabojnikov za strelivo. Before the Second World War, a large underground fortress was built around Goli vrh. Some wood remains in the fort from the time of construction, and some wooden objects have been exhibited in the fort. Several years after the opening of the fort, large scale decomposition was observed on the wood. A sensor for monitoring the relative air humidity and temperature was installed. In addition, a few samples of wood were isolated and examined by X-ray fluorescence spectroscopy and laser confocal linear microscopy. The analysis confirmed the high humidity of the wood and the presence of wood decay fungi on all wood objects, with the exception of wooden ammunition boxes. |
