The Rogaland Anorthosite Province comprises three major massif-type anorthosites, two smaller-sized anorthositic-leuconoritic bodies, as well as a large layered, dominantly noritic intrusion. A mangero-noritic intrusion is found in the northeastern part of the province and major acidic intrusions are located to the far southeast. The Rogaland Anorthosite Province was emplaced into the Sveconorwegian orogenic belt of southwest Scandinavia at 931±3 Ma. Emplacement took place at around 5.5 kbar producing a thermal aureole with osumilite and pigeonite isograds and evidence for dehydration melting. The early history of the hosting terrane most likely dates back to Gothian or late Pre-Gothian times and contain evidence for numerous episodes of folding and deformation. Contact metamorphism was superimposed on a crustal volume, which had been exposed to Sveconorwegian granulite facies metamorphism between 1024 and 970 Ma. Deformation patterns, mineral compositional considerations and geothermobarometry imply that the Rogaland anorthosites crystallized along a P-T trajectory starting at 10-13 kbar, and were emplaced in a mushy state. The possibility that primitive jotunites may be parental to the andesine anorthosites have recently been substantiated, and experimental data show that these jotunites most likely formed by melting of gabbronoritic sources in the lower crust. The 230 km2 Bjerkreim-Sokndal Layered Intrusion also derive from jotunitic parents, and jotunites form a continuous liquid line of descent filling the gap between basic and acidic rocks in Rogaland. This intrusion contains a >7000 m thick layered cumulate sequence, consisting of virtually all the rock types belonging to the anorthosite kindred. The intrusion morphology, layering and compositional variation result from a variety of magma chamber processes, which are discussed in detail. The Rogaland Anorthosite Province also hosts numerous Fe-Ti oxide deposits of variable size, grade and composition. The oxide deposits have been divided into three basic types based on their oxide-phosphate association; type 1: ilmenite-only, type 2: ilmenite + magnetite and type 3: ilmenite + magnetite + apatite. This excursion guide provides detailed itineraries to most parts of the Rogaland Anorthosite Province, with in-depth descriptions of more than 40 key localities, The itineraries cover the various anorthosites, the Bjerkreim-Sokndal Layered Intrusion, jotunitic and acidic intrusions, the hosting metamorphic complex, as well as Fe-Ti oxide and sulfide deposits.

Die Referentin, selbst Sprachberaterin, versteht die individuelle Beratung bei der Textrezeption und -produktion als eine Chance zum lebendigen Austausch zwischen Linguisten und Nichtlinguisten. Individuelle Sprachberatung ist mehr als eine Übersetzung linguistischer Erkenntnisse für Laien. Die Bereitschaft der sprachberatenden Linguisten zur Beeinflussung der Textproduktion setzt voraus, dass eine „reine“ Deskription sprachlicher Phänomene als Utopie bzw. als ein genuin monologisches Verfahren der Grammatikographie erkannt wird. Ob das Gespräch den Sprachberatungskunden letztlich dazu anregt, „wegen des Wetters“ zu schreiben oder „wegen dem Wetter“ – in jedem Falle haben Berater und Kunde auf der Grundlage empirisch gewonnener und deskriptiv ausgewerteter Daten gemeinsam eine Norm formuliert. Sprachberatung kann aber auch nachgerade in der Werbung für die Utopie einer reinen Deskription bestehen, selbst wenn der ursprüngliche Anlass des Gesprächs die Suche nach einer möglichst strengen Norm gewesen ist. Nicht nur wie sprachliche Zweifelsfälle und mögliche Lösungsansätze dargestellt werden, sondern auch welche Fakten präsentiert werden, hängt von einer Reihe spontan – das heißt: in Sekundenschnelle – getroffener Entscheidungen beider Gesprächspartner ab. Bereits beim ersten Kontakt (Begrüßung; Formulierung der Frage) ordnet die Sprachberaterin ihren Gesprächspartner einer Gruppe von Sprachteilnehmern zu und macht sich ein Bild von der Situation, in der dieser Zweifelsfall aufgekommen ist. Von der Bewertung dieser Gesprächssituation hängt es ab, ob die Antwort in einer schnellen impliziten Handlungsanweisung besteht („Der Satz ist korrekt“) oder ob Grundfragen der Linguistik wie die Definition des „Standards“ im Varietätenspektrum, quantitative und qualitative Methoden in der Korpusauswertung, vielleicht sogar sprachphilosophische Fragen thematisiert werden. Im Vortrag sollen am Beispiel einiger Zweifelsfälle aus dem Bereich der Syntax (Moduswahl, Substantivvalenz, Monoflexion) situationsgerechte Gesprächsziele und -strategien herausgearbeitet und zur Diskussion gestellt werden. Neben dem Erkenntnisinteresse und den Gesprächszielen der Anrufer wird das Erkenntnisinteresse der Linguisten zu bedenken sein. Paradebeispiel hierfür ist die Frage, inwiefern die gängigen mehr oder weniger verbzentrierten Grammatikmodelle der Produktion konzeptionell schriftlicher Texte angemessen sind. [less ▲]

Peracarid crustaceans and amphipods in particular are an important group in the Southern Ocean and one of the most diverse in the macrozoobenthos (Jazdzewski et al., 1991). As a part of a multidisciplinary study of the amphipods ecological roles in Antarctic benthic systems (De Broyer et al., 2001, Nyssen et al., 2002), about 150 specimens belonging to 25 species of 10 of the most common amphipod families occurring in the Southern Ocean have been involved in this study of amphipod trophic patterns. Beside “classical” stomach content analysis or field observations, the use of naturally occurring stable isotopes of carbon (δ13C) and nitrogen (δ15N) has recently provided new insights into food web ecology (Hobson & Welch, 1992, Lepoint et al., 2000). This method is based on the direct relationship established between the isotopic signature of an organism and that of its preys (DeNiro & Epstein, 1978, 1981, Peterson & Fry, 1987). Nitrogen-15 typically shows a step-wise increase with trophic level within a food chain (Cabana & Rasmussen, 1994). Closer to the value of the diet, carbon-13 is preferentially used to assess the relative proportion of potential primary sources in a trophic web (ex.: pelagic vs benthic contribution to food intake) (Dauby et al., 1998, Hobson et al., 1995). Furthermore, for several species, the lipid signature – which has already been used successfully to help understand marine trophodynamics (Graeve et al., 2001, Nelson et al., 2001, Phleger et al. 1998) – and more particularly the fatty acid composition has been investigated as trophic biomarkers to reveal more precisely to which trophic guild they belong to.

It has often been claimed that writing about music is like dancing about architecture. The general distrust of methods that combine or aggregate knowledge from different research fields, and therefore tend to elide or smooth out some of their particularities, may account for the paucity of critical writing dealing not only with the role of voice and song in poetry but also with the history of the interdependencies of verbal, textual and musical materials in the broader context of contemporary American literature. The purpose of this book is to develop an informed and imaginative understanding of the interrelationships between poetry and music in a way that reflects the diversity and richness of contemporary artistic practice in the US since the beginning of the 20th century. Related topics such as theories of representation, the aesthetics of rhythm, the material production of literature and music, the links between poetry, politics and popular culture, the making of music from literary texts,or literature from musical models, all provide the focus for a study that deals with the theoretical and practical interrelationships between poetry and music.

Canine herpesvirus is known to be a causal agent of reproduction disorders and diseases of the upper respiratory system. Subclinical infections are also frequently observed. The interest for the virus has risen in recent years especially since latency has been demonstrated and a new vaccine has been developed. In this review article we will successively deal with virus characteristics, epidemiology, pathogenesis, clinical signs, diagnosis as well as therapy and prevention. [less ▲]

The pion structure function is investigated in a simple pseudo-scalar coupling model of pion and constituent quark fields. The imaginary part of the forward Compton scattering amplitude is evaluated. We show that the introduction of non-perturbative effects, linked through a cut-off to the size of the pion, allows the reproduction of important features of the pion quark distribution function.

GIS (Geographical Information Systems) bring an ever increasing range of solutions to decision makers seeking ever more accurate situational awareness in the issues they are facing. In particular, a GIS can provide a broad range of visual information resulting from computations that may be complex. These require to develop and implement efficient algorithms because of the massive amount of computations or data that are induced by the geographical nature of the processed data. The Urban and Rural Planning and Study Lab of University of Liege seeks to compute accessibility profiles for so-called "slow transport modes" in the Walloon Region. In this context, a relevant issue of computation of a socio-economical index based on spatial and population data is considered. The objective of this work is to modelize a problem of computation accessibility index, then solve it. The central part consists of the developement of a consistent and efficient algorithm chain to compute optimal shortest paths in geographical zones by avoiding barriers. The integration of the involved algorithms as well as the exploitation of intermediary results are fundemental aspects of the proposed solution. Two variants of the problem are modelized: DLOSP (Discrete Line-Of-Sight Paths, that does not take barriers into account) and DGSP (Discrete Geodesic Shortest Paths, that takes barriers into account). The detection and indexation of the barrieres, the refitting of the considered search space, the optimization of visibility requests and the computation of shortest paths constitute the main steps of the proposed algorithm chain. A distributed computing setup, naturally stemming from the structure of the problem itself, is briefly presented. [less ▲]
