Title of Dissertation: ROLE OF PEACH [PRUNUS PERSICA (L.) BATCSH] EXTRAFLORAL NECTARIES IN MEDIATING NATURAL ENEMY-HERBIVORE INTERACTIONS Clarissa Ruth Mathews, Doctor of Philosophy, 2004 Dissertation Directed By: Professor Dale G. Bottrell Department of Entomology Extrafloral nectaries (EFNs) are reported to benefit some plants when ants (Hymenoptera: Formicidae) use their secretions and fend ...

Lateral branching plays an important role in the elaboration of adult plants architecture. Herein, we adopted a modified AFLP approach combined with a degenerate primer amplification to identify and isolate in the underinvestigated ornamental species H. rosa-sinensis an orthologous element of the MAX2 gene (More Axillary Branches), which acts downstream of the branching inhibition signaling pat...

The drying process of traditional Chinese medicine Rosa laevigata Michx was investigated in a laboratory scale dryer. Drying experiments were conducted at five temperatures of 40 ̊C, 50 ̊C, 60 ̊C, 70 ̊C and 80 ̊C. The experimental data were fitted to ten different thin layer drying models to select a suitable model for describing the drying process of Rosa laevigata Michx fruits. The results showed ...

In this paper, we present the knowledge-based system rosa working on spatial and functional organizations in agriculture. The reasoning in rosa combines hierarchical classification, case-based reasoning, and qualitative spatial reasoning. The goal of the system is twofold: formalizing and building a case base holding on farm spatial and functional organizations, and helping the analysis of new ...

Learning Content Management Systems (LCMS) supports e-learning applications with storage and efficient access for e-learning objects (LO)s. ROSA is a LCMS built as a semantic layer on the top of an XML native DBMS, Tamino. Together, ROSA and Tamino, offer instructional designers a semantic view of e-learning content. In this paper, we present ROSA Data Model and Query Language, designed as an e...

Learning Content Management Systems (LCMS) supports e-learning applications with storage and efficient access for e-learning objects (LO)s. ROSA is a LCMS built as a semantic layer on the top of an XML native DBMS. In this paper, we present ROSA Data Model designed as an extension to RDF data model with ordered collections and relationship properties and cardinalities. An algebra is proposed wi...

Different types of texture produce differences in slant-discrimination performance (P. Rosas, F. A. Wichmann, & J. Wagemans, 2004). Under the assumption that the visual system is sensitive to the reliability of different depth cues (M. O. Ernst & M. S. Banks, 2002; L. T. Maloney & M. S. Landy, 1989), it follows that the texture type should affect the influence of the texture cue in depth-cue co...
