An algal culture medium was developed which reflects the extreme chemical conditions of acidic mining lakes (pH 2.7, high concentrations of iron and sulfate) and remains stable without addition of organic carbon sources. It enables controlled experiments e.g. on the heterotrophic potential of pigmented flagellates in the laboratory. Various plankton organisms isolated from acidic lakes were successfully cultivated in this medium. The growth rates of an Chlamydomonas- isolate from acidic mining lakes were assessed by measuring cell densities under pure autotrophic and heterotrophic conditions (with glucose as organic C-source) and showed values of 0.74 and 0.40, respectively.
Adverbs and Adjunction
(2000)
The papers collected in this volume were all presented at the workshop on Adverbs and Adjunction, held at the University of Tromsoe, in April 17-18, 1999. The presentations by Kristin M. Eide &Inghild Flaate, Henriette de Swart, Artemis Alexiadou and Adam Wyner could not be included here.
The articles deal with the syntax, semantics and morpbology of adverbs and their interaction with other syntactic phenomena. A number of tbe contributions is concerned with an evaluation of the hypothesis that adverbs are specifiers of functional heads, which are universally ordered. Specifically, Adger &Tsoulas argue that locative adverbials are licensed by an aspectual head that encodes telicity, while manner adverbials are licensed by a light verb that encodes agentivity, both being situated low in the VP structure. According to the authors, the prime function of these heads is to license aspects of the featural composition of the object, and the licensing of these low adverbials is a by-product of the way that the EPP features of these heads functions. Costa presents data from European Portuguese in support of the traditional analysis of adverbs as adjuncts. Ernst shows that manner, measure, and domain adverbs, and more generally, adverbs and other adjuncts such as participant PPs and adjunct secondary predicates (depictives), are not rigidly ordered. Hence the paper supports theories where linear order is largely a function of the interaction of compositional rules for the various adjuncts, plus their lexico-semantic requirements.
For Haider, adverbials are adjoined or embedded, depending on the relation to the head of the containing phrase: they are adjoined if they precede the head of the containing phrase. They are embedded if they follow the head of tbe containing phrase. But the relative order of adverbials is a reflex of an interface condition. Moreover, the order pattern of adverbials in the extraposition domain is a function of linear incrementality in a non-compositional subdomain. Laenzlinger, on the other hand, claims that adverbs occupy the A'-specifier of their semantically related functional projection. They are formally licensed via the mechanism of feature checking, which links their distribution to their interpretation. He also considers adverb placement and its interaction with Verb/Argument Movement, fronting and extraposition. The interaction between A-scrambling and adverb placement crosslinguistically is also investigated by Hoffman in a minimalist framework. He claims that adverbs can be pronounced in any set of syntactic positions, but the choice among the various positions is made on non syntactic grounds.
Two papers are concerned with adverbial case. Pereltsvaig examines nominal adverbials marked with Accusative Case, with particular focus on Russian and Finnish. She shows that Accusative adverbials exhibit object-like behavior. She argues that Accusative Case is related to aspectual properties of the VP, and it is thus argued that Structural Accusative Case is checked in [Spec, AspP]. But not all occurrences of morphological accusative case derive from Structural Accusative Case. Thus, the contrasts between Russian and Finnish are explained by the claim that Russian uses accusative case marking for NPs in default objective Case position, whereas Finnish uses partitive in the same position. Manninen shows that in Finnish- adverbs can be analyzed as a sub-category of adjectives and nouns, as they are really case-inflected adjectives and nouns. Manninen proposes that these bear lexical 'adverb' case, i. e. that is they have the form of K(asus;Kase)Ps.
Finally, Vegnaduzzo investigates the polysemy of the ltalian adverb ancora showing that this is only apperent. She argues that all the different readings depend upon the context where it is inserted: each reading is derived by compositionality of ancora basic meaning and the semantic properties of the argument structure of the verb.

Microlensing results from APO monitoring of the double quasar Q0957+561A,B between 1995 and 1998
(2000)
If the halo of the lensing galaxy 0957+561 is made of massive compact objects (MACHOs), they must affect the lightcurves of the quasar images Q0957+561 A and B differently. We search for this microlensing effect in the double quasar by comparing monitoring data for the two images A and B - obtained with the 3.5m Apache Point Observatory from 1995 to 1998 - with intensive numerical simulations. This way we test whether the halo of the lensing galaxy can be made of MACHOs of various masses. We can exclude a halo entirely made out of MACHOs with masses between 10-6 Msun and 10-2 Msun for quasar sizes of less than 3x 1014 h60-1/2 cm, hereby extending previous limits upwards by one order of magnitude.
Menschenrechte
(2000)
Das erste umfassende deutschsprachige Lexikon über die Vereinten Nationen enthält einen menschenrechtlichen Schwerpunktteil. Dieser Beitrag gibt eine grundlegende Einführung in die geistesgeschichtliche Entwicklung der Menschenrechte. Außerdem erläutert er in geraffter Form die Normierung von Menschenrechten auf der universellen Ebene. Abschließend werden verschiedene, häufig diskutierte Problemfelder behandelt. Hierzu zählen Fragen der Universalität von Menschenrechten, das Recht auf Entwicklung und die Durchsetzung und Förderung von Menschenrechten.
Nach einleitenden Ausführungen über die Maßnahmen zum Schutz von Frauenrechten im Rahmen der Vereinten Nationen insgesamt konzentriert sich der Beitrag auf die Darstellung des Übereinkommens zur Beseitigung jeder Form von Diskriminierung der Frau (CEDAW). Dessen materielle Gewährleistungen werden erläutert und der zugehörige Überwachungsmechanismus vorgestellt. Ein abschließender Ausblick stellt die Neuerungen dar, die mit den Individualbeschwerdeverfahren verbunden sein werden, die durch das inzwischen in Kraft getretene Zusatzprotokoll zu erwarten sind.

Kinetic analysis of the thermic effect of food and its relationship to body composition in humans
(2000)
The course of energy expenditure after a meal can vary widely with regard to the slope of onset, amplitude, and duration of the thermic effect. The aim of the present study was to explore the relationship between the thermic effect of food (TEF), as characterized by kinetic analysis of postprandial energy expenditure, body composition, and variables related to the metabolic syndrome including central obesity, hypertension, and glucose tolerance. A total of 181 men and women (body mass index [BMI] range, 19.4 to 52.2 kg/m2) were characterized for body composition, blood pressure, oral glucose tolerance, and energy expenditure after a test meal. Energy expenditure, as measured by indirect calorimetry, was analyzed over a 6-hour period by 3-parameter curve fitting using equations derived from kinetics describing a biphasic reaction involving 2 consecutive first-order reactions (A->B->C). Apart from total thermic effect of food (TEFk), the curve also provided an estimate of time of peak (Tp) and amplitude of peak (Ap) for each subject. Multiple stepwise regression analysis with TEFk, Ap, and Tp as dependent variables showed significant effects of sex, age, body weight, body fat, -blockade, and body composition on TEF curve parameters. Cluster analysis based on Tp shown 2 distinct clusters with significant differences in age and body fat mass. This study shows that kinetic analysis of postprandial energy expenditure can be used to examine the determinants of the time course of the thermic effect of food in man.
