(1998) Bradley, Peter; Rozenfeld, Anatoly; Lee, Kevin; Jamieson, Dana; Heiser, Gernot; Satoh, SJournal ArticleThe first results obtained using a SOI device for microdosimetry applications are presented. Microbeam and broadbeam spectroscopy methods are used for determining minority carrier lifetime and radiation damage constants. A spectroscopy model is presented which includes the majority of effects that impact spectral resolution. Charge collection statistics were found to substantially affect spectral resolution. Lateral diffusion effects significantly complicate charge collection
(1998) Lutze, J; Roden, J; Holly, C; Wolfe, Joseph; Egerton, J; Ball, MalcolmJournal ArticleGrowth under elevated [CO2] promoted spring frost damage in field grown seedlings of snow gum (Eucalyptus pauciflora Sieb. ex Spreng.), one of the most frost tolerant of eucalypts. Freezing began in the leaf midvein, consistent with it being a major site of frost damage under field conditions. The average ice nucleation temperature was higher in leaves grown under elevated [CO2] (– 5.7 oC versus – 4.3 oC), consistent with the greater incidence of frost damage in these leaves (34% versus 68% of leaves damaged). These results have major implications for agriculture, forestry and vegetation dynamics, as an increase in frost susceptibility may reduce potential gains in productivity from CO2 fertilization and may affect predictions of vegetation change based on increasing temperature.

(1999) Taft, Marcus; Zhu, Xiaoping; Peng, Danling; Ding, Guosheng; Wang, ChaoyuanJournal ArticleFour experiments investigated the role of morphemes in the recognition of Chinese two--character words and its mutation in the bine course of processing. In all of the experiments, semantic priming procedure was used and Chinese reversible words as primer. In Exp 1, it was found that the presentation of a reversible word can,when SOA is 157ms, facilitate not only the lexical decision of a target which has semantic relation with the reversible word, but also that of a target which has semantic relation with its reversed form. There was no difference of priming effects between the two conditions. In Exp 2 (SOA = 314ms) and Exp 3 (SOA = 57ms), the resultS showed that the presentation of a reversible word can significantly facilitate only the decision of one of its semantically related words, but not that of one which has semantical relation with its reversed form. These results were also obtained in Exp 4which was controlled more strictly. Three points were concluded. First, the morpheme whiz played some roles in the recognition of words, but its activation was not a necessary stage. Second, in the process of recognition, the antivation of morpheme units came through from weaness to strength, then to weakness gradually, while that of whole word units was constantly strengthened.Third, the information of the position of morphemes was processed later than that of morpheme units themselves.
