When radiocarbon dating of the conserved woods is conducted, we must eliminate the resin from the woods because it was made from coal oil. Of cause, the waterlogged woods have every condition that will be indicated by information such as moisture content and several species. Then, in this study, we performed elimination of polyethylene glycol from known age test samples which were prepared to this study from waterlogged woods of several species and moisture content distributed around 100-1000%. In addition, chestnut trees excavated from the Mawaki archaeological site, Japan, and conserved with polyethylene glycol were radiocarbon dated after the elimination process. To verify the estimated dates, the chestnut trees were cross dated dendrochronologically to other woods which were already dated precisely by wiggle matching.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u7b2c21\u56de\u540d\u53e4\u5c4b\u5927\u5b66\u5e74\u4ee3\u6e2c\u5b9a\u7dcf\u5408\u7814\u7a76\u30bb\u30f3\u30bf\u30fc\u30b7\u30f3\u30dd\u30b8\u30a6\u30e0\u5e73\u621020(2008)\u5e74\u5ea6\u5831\u544a", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.20.124", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u540d\u53e4\u5c4b\u5927\u5b66\u5e74\u4ee3\u6e2c\u5b9a\u8cc7\u6599\u7814\u7a76\u30bb\u30f3\u30bf\u30fc"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u897f\u672c, \u5bdb"}], "nameIdentifiers": [{"nameIdentifier": "82894", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4e2d\u6751, \u664b\u4e5f"}], "nameIdentifiers": [{"nameIdentifier": "82895", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u9ad8\u7530, \u79c0\u6a39"}], "nameIdentifiers": [{"nameIdentifier": "82896", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4e2d\u6751, \u4fca\u592b"}], "nameIdentifiers": [{"nameIdentifier": "82897", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u6728\u6751, \u52dd\u5f66"}], "nameIdentifiers": [{"nameIdentifier": "82898", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishimoto, Hiroshi"}], "nameIdentifiers": [{"nameIdentifier": "82899", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Shinya"}], "nameIdentifiers": [{"nameIdentifier": "82900", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takada, Hideki"}], "nameIdentifiers": [{"nameIdentifier": "82901", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "82902", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kimura, Katsuhiko"}], "nameIdentifiers": [{"nameIdentifier": "82903", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "nishimoto2008.pdf", "filesize": [{"value": "5.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 5300000.0, "url": {"label": "nishimoto2008.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/12821/files/nishimoto2008.pdf"}, "version_id": "43685e24-4ac0-46f4-a8fa-1d7a137f9193"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u4fdd\u5b58\u51e6\u7406\u3055\u308c\u305f\u907a\u8de1\u51fa\u571f\u6728\u6750\u306e14C\u5e74\u4ee3\u6e2c\u5b9a : PEG\u9664\u53bb\u65b9\u6cd5\u306e\u691c\u8a0e", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u4fdd\u5b58\u51e6\u7406\u3055\u308c\u305f\u907a\u8de1\u51fa\u571f\u6728\u6750\u306e14C\u5e74\u4ee3\u6e2c\u5b9a : PEG\u9664\u53bb\u65b9\u6cd5\u306e\u691c\u8a0e"}]}, "item_type_id": "9", "owner": "1", "path": ["879/1183/1184/1312"], "permalink_uri": "https://doi.org/10.18999/sumrua.20.124", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2011-04-28"}, "publish_date": "2011-04-28", "publish_status": "0", "recid": "12821", "relation": {}, "relation_version_is_last": true, "title": ["\u4fdd\u5b58\u51e6\u7406\u3055\u308c\u305f\u907a\u8de1\u51fa\u571f\u6728\u6750\u306e14C\u5e74\u4ee3\u6e2c\u5b9a : PEG\u9664\u53bb\u65b9\u6cd5\u306e\u691c\u8a0e"], "weko_shared_id": null}
