This report concerns a case with unusual lesions consisting of massive destruction of myelinated fibres in a thin marginal layer at the surface of the spinal cord, brain-stem, optic nerve and tract, without involvement of the superficial portions of grey matter. The lesions showed a striking similarity to those produced by barbotage (aspiration and reinjection of cerebrospinal fluid) in experim...

This introductory chapter is mainly addressed to readers new to the field. In Sect. 1.1 a brief review of the historical roots of the current research is given. Section 1.2 describes various spin interactions. Section 1.3 is a mini text-book on semiconductor physics designed for beginners. A short overview of spin phenomena in semiconductors is given in Sect. 1.4. Finally, Sect. 1.5 presents th...

Das Bunge-Wand-Weber-Modell wurde in der Literatur bereits angewendet, um Modellierungssprachen wie das Entity-Relationship-Model oder die Unified Modeling Language zu evaluieren. In diesem Beitrag wird aufbauend auf dem Bunge-Wand-Weber-Modell eine Methode zur Evaluierung von Referenzmodellen eingeführt. Zentrales Konzept dieser Methode ist die ontologische Normalisierung eines Referenzmodells...

Rubus L. is a large and taxonomically complex genus, species of which exhibit apomixis, polyploidy, and frequent hybridization. Most of Chinese Rubus are assigned in two major sections, Idaeobatus and Malachobatus. To explore the phylogenetic relationships within Chinese Rubus, inferences upon three chloroplast DNA (rbcL, rpl20-rps12, and trnG-trnS), nuclear ribosomal ITS, and two low-copy nucl...

studies on contents of phenolic compounds and diterpenes in Salvia miltiorrhiza Bunge root during the vegetation period were carried out. In Polish climate and soil condition, the tanshinone II a occurred as the dominant compound from diterpenes group. obtained results show that the most profitable period for harvesting Salvia miltiorrhiza raw material is fructification stage. however, it is ve...

The Leptostemonum clade of Solanum contains approximately 350–450 species, including the cultivated eggplant, S. melongena . This clade is characterized by the presence of prickles and apically attenuate anthers. Solanum section Androceras , the focus of this study, is a group of ca. 12 species belonging to the Leptostemonum clade. This section is unusual in the genus because of its mostly nort...

The Dulcamaroid clade of Solanum contains 45 species of mostly vining or weakly scandent species, including the common circumboreal weed Solanum dulcamara L. The group comprises members of the previously recognised infrageneric groupings sect. Andropedas Rusby, sect. Californisolanum A. Child, sect. Dulcamara (Moench) Dumort., sect. Holophylla (G.Don) Walp., sect. Jasminosolanum (Bitter) Seithe...

Finite element technologies have been applied to fluid dynamrcs problems for some time now. The early work focused on Galerkin 's method and various attempts to improve its stability while retaining its basic character. In the late 1970s a new approach was introduced, namely, "stabili zed methods," such as SUPG and Galerkin/least-s quares. These methods have been applied to many areas in fluid ...
