Measurements have done with the specimens successively obtained from the pith to the sapwood. Methods of investigation were similar to those shown in previous reports, and the items were as follows 1) Anatomical structure 2) Physical properties (1) The mean micellar angle and crystallinity index (2) The variation of specific gravity in radial direction (3) Shrinkage 3) Mechanical properties (1) Compression (2) Bending (3) Impact bending (4) Cleavage strength (5) Shearing strength (6) Hardness The results showed that neither shrinkage nor mechanical properties represent appreciable correlation with specific gravity in air dry in contrast to the good correlation observed in the South East Asian woods in previous reports. This disagreement is likely caused by interlocked grain of three African woods in this report.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55697","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIWA, Yushiro"}]},{"nameIdentifiers":[{"nameIdentifier":"55698","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MISHIRO, Akiyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"55699","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OKANO, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"55700","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ASANO, Ikuo"}]}]},"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":"東京大学農学部林産学科"},{"subitem_text_value":"Department of Foest Products, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三輪, 雄四郎"}],"nameIdentifiers":[{"nameIdentifier":"55693","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三城, 昭義"}],"nameIdentifiers":[{"nameIdentifier":"55694","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡野, 健"}],"nameIdentifiers":[{"nameIdentifier":"55695","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅野, 猪久夫"}],"nameIdentifiers":[{"nameIdentifier":"55696","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":"2017-06-12"}],"displaytype":"detail","filename":"esrh071007.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh071007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25629/files/esrh071007.pdf"},"version_id":"0327dcd5-ba67-4f56-8aa3-e26e881c948c"}]},"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":"木材の基礎的材質に関する研究(第3報） Ovangkol (Guibourtia sp.), Sapele (Entandrophragmasp.) および Makore (Tieghemella sp.)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"木材の基礎的材質に関する研究(第3報） Ovangkol (Guibourtia sp.), Sapele (Entandrophragmasp.) および Makore (Tieghemella sp.)"}]},"item_type_id":"4","owner":"1","path":["2600","2599"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25629","relation_version_is_last":true,"title":["木材の基礎的材質に関する研究(第3報） Ovangkol (Guibourtia sp.), Sapele (Entandrophragmasp.) および Makore (Tieghemella sp.)"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:48.407371+00:00"}
