Long-term natural ageing reduces the hygroscopicity of wood while improving its acoustic quality, but these changes are partly reversible by exposure to high humidity. Similar reversible changes are observed in hydrothermally treated wood, especially when the wood is heated at an intermediate relative humidity. These reversible changes are attributed to the annealing-like rearrangement of amorphous wood polymers or the temporary closure of micropores, but further investigation is necessary. Color change resulting from natural ageing is shown to be successfully reproducible by oven-heating.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.culher.2016.02.011","subitem_relation_type_select":"DOI"}}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"OBATAYA, Eiichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-01"}],"displaytype":"detail","filename":"Obataya_JCH.pdf","filesize":[{"value":"585.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"Obataya_JCH","url":"https://tsukuba.repo.nii.ac.jp/record/39330/files/Obataya_JCH.pdf"},"version_id":"cf423797-ec6a-43ab-9c0a-3209fadd661a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Wood","subitem_subject_scheme":"Other"},{"subitem_subject":"ageing","subitem_subject_scheme":"Other"},{"subitem_subject":"musical instrument","subitem_subject_scheme":"Other"},{"subitem_subject":"hygroscopicity","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic property","subitem_subject_scheme":"Other"},{"subitem_subject":"Wood","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ageing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"musical instrument","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hygroscopicity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic property","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effects of natural and artificial ageing on the physical and acoustic properties of wood in musical instruments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of natural and artificial ageing on the physical and acoustic properties of wood in musical instruments"},{"subitem_title":"Effects of natural and artificial ageing on the physical and acoustic properties of wood in musical instruments","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["4750","5429"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-09-29"},"publish_date":"2016-09-29","publish_status":"0","recid":"39330","relation_version_is_last":true,"title":["Effects of natural and artificial ageing on the physical and acoustic properties of wood in musical instruments"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:09:23.832594+00:00"}
