Selenides of the type R1Se-EMe3 (E = Si, Ge, Sn, Pb) react with xenon difluoride by cleavage of the Se-E bond to yield the R1Se-F intermediate and the fluorides Me3E-F, whereas the Se-C bond in PhSe-tBu (E = C) is stable against XeF2. The presence of R1Se-F intermediates is confirmed by addition to acetylenes (4-octyne, 3-hexyne). Thus, the fluoroselenenylation of acetylenes gives fluoro(organylseleno)olefins in preparative yields. In the cases of E = Si, Ge, Sn, and Pb, aryl and n-alkyl groups are suitable as the substituent R1. The X-ray crystal structural analysis of (E)-3- (p-carboxyphenylseleno)-4-fluorohex-3-ene - the first example of an uncharged fluoroselenoolefin synthesized from p- EtO2C-C6H4-Se-SnMe3, XeF2, and 3-hexyne followed by an ester hydrolysis - shows that the addition of the selenenylfluoride intermediate to the acetylene proceeds via a trans-addition, as is known for the R2Se2-XeF2 reagents.

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.
Am Beispiel eines modellierten Deponiesickerwassers wird die Möglichkeit einer simultanen Reaktivextraktion von toxischen Schwermetallen aus einer unproblematischen Matrix vorgestellt. Als Extraktionsmittel werden vergleichend Alkylphosphorsäuren (kommerzielle D2EHPA, D2EHTPA), ß-Diketone, 4-Acylpyrazol-5-one und eine neuartige kommerzielle Alkylphosphonsäure eingesetzt. Die thermodynamischen Parameter der Extraktion lassen sich mit Hilfe der Funktionen %E = f( t, pH), lg D = f ( pH, cL) bestimmen. Einflüsse von Lösungsmitteln und konkurrierende Komplexbildner in der wäßrigen Phase auf das Verteilungsgleichgewicht werden diskutiert. Inhaltsstoffe der wäßrigen Phase (Cyanid, Tartrat, Ammoniak, Huminsäuren oder Chlorid) beeinflussen entsprechend ihrer Ligandstärke die Metallabtrennung. Für den Fall der Huminsäure wird eine Größenordnung von Weinsäure gefunden. Sulfationen erschweren zusätzlich die Extraktion von Calcium. Halogenierte und aromatische Verdünnungsmittel haben gegenüber unproblematischen Kohlenwasserstoffen keinen Vorteil. Mit Aminomethylphosphonsäure (Ironex, BASF) gelingt eine quantitative Eisen, Indium- und Galliumabtrennung bei einem pH-Wert kleiner 1.5 als ML2(HL) bzw. ML(HL)2. Kupfer und Zink werden im pH-Bereich von 4-6 quantitativ als 1:2- Komplex extrahiert. Insgesamt günstige Ergebnisse zeigen die ß-Diketone (auch LIX 54) und 4-Acylpyrazol-5-one. Hier ergibt sich die Möglichkeit toxische Schwermetalle selektiv abzutrennen und eine unproblematische Matrix zu gewinnen, da Calcium nur zu 6% und Magnesium zu 23% extrahiert werden.

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.

As traduccions para as linguas en proceso de normalizacion responden a unhas necesidades diferentes do que as traduccions que se fan, por exemplo, as linguas nacionais. A contribucion pretende unha analise ben polo miudo dunha traduccion galega de Asterix comparandoa co orixinal francés e coa traduccion espanola. En casos como o do galego, que durante moito tempo non contaba cunha norma fixada (ata hoxe, a norma fixada no ano 1982 e reformada en 1993 é discutida e probablemente sera reformada outra vez), a traduccion adquire unha importancia moi especial, pois a literatura en lingua galega, ademais de formar parte da normalizacion da lingua contribue a que a norma sexa reconecida e espallada na poboacion, ainda non moi acostumada a ve-la sua lingua escrita. A traduccion de comics por conseguinte xoga un papel moi importante xa que o seu obxectivo é sobre todo normalizar o uso da lingua galega nas xeracións novas e familiariza-la xuventude coa norma. Unha crítica das traduccións de cómics, por todo iso, ten que estar baseada tanto nunha análise orientada no texto de partida (unha comparación co texto de partida) como nunha análise orientada no texto de chegada, considerando aspectos externos do proceso de traducción e avaliando a eficacia do texto de chegada como ferramenta normalizadora.
