On the other\nhand, polymeric materials included in parts of irradiation\nfacilities or in nuclear plants are subjected to the action of\nionizing radiation in the presence of air. These facts explain\nthe high interest in the study of radiation effects on\npolymers. Timber is a polymeric material and also it is\nsuccessfully employed as a structural or decorative material\nin a wide variety of application. In Myanmar, timber is\nextensively employed as a structural and decorative material\nin a wide variety of applications as well as being a major\nexport commodity. In fact, the commercially important\ntimber species will become scarce due to the development of\nwood- based industries and increased domestic and\ninternational trade. Thus, the Forest Department has\nconsidered that commercially important timber should be\nsubstituted by other appropriate woody species or by some\nlesser-used timber species (LUS). In collaboration with\nInternational Tropical Timber Organization (ITTO), the\nForest Department has undertaken a project on “Introducing\nM y a n m a r ’ s L e s s e r -Used T imb e r S p e c i e s t o t h e\nWorld Market”. The radiation techniques for the\nimprovement of the quality of these LUS are new to us. In\nthis project, the changes in physical properties such as\ndimensional changes and specific gravity, and mechanical\nproperties such as static bending test, compression tests and\nhardness tests of Leza, a lesser used Myanmar timber species,\nfollowing radiation processing with 10kGy gamma radiation\nhas been studied. The timber samples were obtained from\nTimber Physical Section and Timber Mechanical Section,\nForest Research Institute (F.R.I), Yezin and these samples\nwere informed to be collected from Kabaung Reserve Forest\nof Taunggu Forest Division. The results for these tests were\nanalyzed at 95 percent confidence level by using Statistical\nAnalysis System. The results revealed that although the\nphysical properties of Leza are not significantly changes at 95\npercent confidence level, the results for strength properties of\nLeza are significantly changed at 95 percent confidence\nlevel after gamma radiation."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Gamma Radiation"}, {"interim": "Irradiation"}, {"interim": "Timber"}, {"interim": "Leza"}, {"interim": "Strength Properties"}, {"interim": "Physical Properties"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-12-16"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Studies on Changes of Properties of Wood.pdf", "filesize": [{"value": "3.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 3400000.0, "url": {"url": "https://meral.edu.mm/record/6861/files/Studies on Changes of Properties of Wood.pdf"}, "version_id": "1eba2c99-fffa-4f51-9e65-0102c92abe73"}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_acronym": "MURC", "subitem_c_date": "24-5-2019", "subitem_conference_title": "Myanmar Universities’ Research Conference", "subitem_place": "Yangon, Myanmar", "subitem_website": "https://www.nepc.edu.mm/"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Kay Thwe Kywe Aye"}, {"subitem_authors_fullname": "Myo Myo Aung"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Conference paper"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2019-05-24"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://www.nepc.edu.mm/"}, "item_title": "The Studies on the Changes of Properties of a Myanmar Lesser used Timber Species Following Gamma Irradiation", "item_type_id": "21", "owner": "71", "path": ["1582963674932", "1597397207532"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000006861", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-12-16"}, "publish_date": "2020-12-16", "publish_status": "0", "recid": "6861", "relation": {}, "relation_version_is_last": true, "title": ["The Studies on the Changes of Properties of a Myanmar Lesser used Timber Species Following Gamma Irradiation"], "weko_shared_id": -1}
