• EXTRACTIVES FROM POPULUS TREMULOÏDES HEARTWOOD: THE STRUCTURE AND SYNTHESIS OF TREMULONE
  作者：R. A. Abramovitch、R. G. Micetich

  DOI：10.1139/v62-309

  日期：1962.10.1

  Tremulone, a dienone isolated from Populus tremuloïdes heartwood, has been shown to be stigmasta-3,5-diene-7-one. This has been confirmed by a partial synthesis from β-sitosterol. The possibility that tremulone might be an artifact arising from the isolation procedure is discussed.

  Tremulone，一种从白杨木心材中分离出的二烯酮，已被证实为硬脂酸甾醇-3,5-二烯-7-酮。这已通过从β-谷甾醇的部分合成得到证实。讨论了tremulone可能是由于分离过程中产生的人为产物的可能性。

• Pragmatic guidelines for determining road investment priorities in developing countries
  作者：Brian Field、Duncan Hamilton

  DOI：10.1080/13504500209470118

  日期：2002.9

  In many developing countries, the determination of a ranking of investments designed to improve and extend the road system is a commonplace prerequisite of planning for the transport sector as a whole and the road sub-sector within it. A major objective of determining investment priorities is to secure the greatest efficiency in the use of resources allocated to the sector and, for this reason, any system of assigning priorities must rely upon conventional investment appraisal techniques producing quantifiable measures of worth. Exercises of this kind, in which road investments are identified and ranked, are usually undertaken to produce a road sector investment plan. The implementation of such plans is, however, often compromised because of perceived deficiencies with a methodology which places undue reliance on investment appraisal and fails to properly address the issue of public interest and sustainability. This paper attempts to produce a pragmatic set of ground rules which, while mindful of the need to promote economic efficiency, allow for other factors to be embraced in a more holistic methodology.
