The logging residue species were Yezo spruce (Picea jezoensis), Todo-fir (Abies sachalinesis), Lime (Tilia japonica) and Birch (Betula ermanii), whereas the unused species was Poplar (Poplus maximowiczii). The following properties of OSB were measured: the MOE and MOR in air-dry condition and after 2-hour boiling, internal bond strength and thickness swelling. The values for the properties of OSB made from such a mixture of softwood and hardwood ranged between those of the lightest softwood and those of the heaviest hardwood. Accordingly it seems that these properties are not influenced by mixing softwood and hardwood, as long as the OSB is not made of a single species. This implies that flakes produced from a single species must be stocked and then mixed with other softwood and hardwood species in the production of OSB.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54665","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAMURA, Noboru"}]},{"nameIdentifiers":[{"nameIdentifier":"54666","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATOH, Takao"}]},{"nameIdentifiers":[{"nameIdentifier":"54667","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HUKINO, Shin"}]},{"nameIdentifiers":[{"nameIdentifier":"54668","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HORIE, Hideo"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部附属演習林北海道演習林"},{"subitem_text_value":"北海道立林産試験場"},{"subitem_text_value":"University Forest in Hokkaido, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"Hokkaido Forset Products Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 昇"}],"nameIdentifiers":[{"nameIdentifier":"54661","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐藤, 孝夫"}],"nameIdentifiers":[{"nameIdentifier":"54662","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吹野, 信"}],"nameIdentifiers":[{"nameIdentifier":"54663","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"堀江, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"54664","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh096007.pdf","filesize":[{"value":"501.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh096007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25426/files/esrh096007.pdf"},"version_id":"7fdf9797-1eb7-4759-afe3-b91af4504adc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"OSB","subitem_subject_scheme":"Other"},{"subitem_subject":"針葉樹と広葉樹の混合","subitem_subject_scheme":"Other"},{"subitem_subject":"林地残材","subitem_subject_scheme":"Other"},{"subitem_subject":"未利用樹種","subitem_subject_scheme":"Other"},{"subitem_subject":"OSBの性能","subitem_subject_scheme":"Other"},{"subitem_subject":"OSB","subitem_subject_scheme":"Other"},{"subitem_subject":"Logging residue","subitem_subject_scheme":"Other"},{"subitem_subject":"Unused species","subitem_subject_scheme":"Other"},{"subitem_subject":"Mixture of softwood and hardwood","subitem_subject_scheme":"Other"},{"subitem_subject":"Properties of OSB","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"林地残材および未利用樹種より製造された針葉樹，広葉樹混合OSBの性能","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"林地残材および未利用樹種より製造された針葉樹，広葉樹混合OSBの性能"}]},"item_type_id":"4","owner":"1","path":["2550","2549"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25426","relation_version_is_last":true,"title":["林地残材および未利用樹種より製造された針葉樹，広葉樹混合OSBの性能"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:40.277629+00:00"}
