Direct laser initiation of PETN  

Energy Technology Data Exchange (ETDEWEB)

In the early 1970s Yang and Menichelli demonstrated that direct laser illumination of low-density secondary explosive prr:ssings through a transparent window could produce detonation. 'The energy requirement for threshold initiation of detonation was reduced when a thin metal coating of metal covered the side of the window against which the low-density explosive was pressed. We have obtained experimental results that are in general agreement with the results of Renllund, Stanton and Trott (1 989) and recent: work by Nagayama, hou and Nakahara (2001). We report exploration of the effects of laser beam diameter, PEiTN density and specific surface area, and thickness of a titanium coating on the window.

FY 1997 report on the survey of potential impacts of enlarging ASEAN on political and economic systems in South East Asia; 1997 nendo chosa hokokusho (ASEAN kakudai no Higashi Asia no seiji keizai chitsujo eno eikyo chosa)  

Energy Technology Data Exchange (ETDEWEB)

This report surveys potential impacts of ASEAN (Association of South East Asian Nations) on inter-ASEAN affairs and its external relations when ASEAN will enlarge its members to include all nations in South East Asia, and thus fully represent the region. For this purpose, the survey was conducted on Vietnam, Myanmar, Laos and Cambodia, which joined in 1995, from the viewpoint of their economic and political system, and their relations with other member countries. The nature of ASEAN has gradually transformed, in which all the countries in the region have increased and internal economic issues have been tackled. It has an aim to stimulate inter-ASEAN trade and induce foreign direct investment into ASEAN as a whole by reducing import duties on intra-ASEAN trade. Underlying in these, new development is a concern about growing economic and military power of China. ASEAN solidarity will work an leverage against China should change toward worse, and ASEAN will function as a regional ...
