A Carnation ringspot virus (CRSV) variant (1.26) was identified that accumulates virions but is incapable of forming a systemic infection. The 1.26 capsid protein gene possesses a Ser-->Pro mutation at amino acid 282. Conversion of 1.26 amino acid 282 to Ser restored systemic infection, while the reciprocal mutation in wild-type CRSV abolished systemic infection. Similar mutations introduced in...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporaDly with petal-inroDling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

Due to the development of embed computer, improvement the bandwidth of computer is required, in order to break the choke point of the bus’ development. The text brings a hardware design method of computer based on CompactPCI Express bus, introduces the architecture of system and principle, goes into descriptions abouth the design of Swithboard, bridgeboard and rapid serial single PCB etc. The u...

This paper focuses on the issue of ontological analysis for organizational structure modeling in the ARIS method with the following contributions: (i) an interpretation of the language in terms of realworld entities in the UFO foundational ontology; (ii) the identification of inappropriate elements of the language, using a systematic ontology-based analysis approach; and (iii) recommendations f...

A correction is needed for the singular case X = ∅ in Theorems 4.9, 4.10, 5.1, and 5.2. In Kontinen and Väänänen (2009), the open formulas of Dependence Logic (D) were studied. Formulas of dependence logic express properties of sets of assignments (teams). It was shown in Väänänen (2007) that every formula of dependence logic can be represented in an equivalent form in existential second-order ...
