Relying on the existing estimates for the production cross sections of mini black holes in models with large extra dimensions, we review strategies for identifying those objects at collider experiments. We further consider a possible stable final state of such black holes and discuss their characteristic signatures. Keywords: Black holes
The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality. The species described by Linnaeus are listed. The morphology of all life history stages (adults, larvae, and pupae) is diagnosed and major features of the anatomy are illustrated. Major components of life history and biology are summarized. A discussion of phylogenetic studies within the order is presented, including higher classification of the suborders and superfamilies, based on recent literature. Synopses of each of 45 families are presented, including the taxonomic history of the family, a list of all known genera in each family, their general distribution and relative species diversity, and a short overview of family-level biological features. The order contains 600 genera, and approximately 13,000 species.
Lepidoptera phylogeny and systematics : the state of inventorying moth and butterfly diversity
(2007)
The currently recognized robust support for the monophyly of the Lepidoptera (and the superorder Amphiesmenoptera comprising Lepidoptera + Trichoptera) is outlined, and the phylogeny of the principal lineages within the order is reviewed succinctly. The state of the taxonomic inventory of Lepidoptera is discussed separately for ‘micro-moths’, ‘macro-moths’ and butterflies, three assemblages on which work has followed historically somewhat different paths. While currently there are about 160,000 described species of Lepidoptera, the total number of extant species is estimated to be around half a million. On average, just over one thousand new species of Lepidoptera have been described annually in recent years. Allowing for the new synonyms simultaneously established, the net increase in species numbers still exceeds 800/year. Most of the additions are foreseeable in the micro-moth grade, but even for butterflies ca 100 species are added annually. Examples of particularly interesting new high-rank taxa that have been described (or whose significance has become realized) since the middle of the 20th century include the non-glossatan lineages represented by Agathiphaga and Heterobathmia and the heteroneuran families Andesianidae, Palaephatidae, Hedylidae and Micronoctuidae. Some thoughts on how present and future systematic lepidopterology might be prioritised are presented.
Event-by-event multiplicity fluctuations in nucleus-nucleus collisions from low SPS up to RHIC energies have been studied within the HSD transport approach. Fluctuations of baryonic number and electric charge also have been explored for Pb+Pb collisions at SPS energies in comparison to the experimental data from NA49. We find a dominant role of the fluctuations in the nucleon participant number for the final hadron multiplicity fluctuations and a strong influence of the experimental acceptance on the final results.

Löst man seinen Blick, vielleicht nur für einen kurzen Augenblick, vom Gros der den Weltmarkt des Kinos (gemessen an Verbreitung, Umsatz und Publikumszuspruch) vielleicht mehr denn je beherrschenden Mainstream-Produktionen Hollywood’scher Prägung und richtet diesen etwa gen Osten, genauer: auf die asiatische Filmproduktion der letzten zehn bis fünfundzwanzig Jahre, so fällt auf, dass neben vielen Filmemachern, die bereitwillig auf den reichen Fundus an filmischen Ausdrucksmöglichkeiten, an Genrekonventionen, etc. zurückgreifen, zum Teil auch einen eher spielerischen Umgang damit pflegen, diese etwa mit geographischen/kulturellen/etc. Spezifika zu mitunter aufregenden hybriden Filmwerken amalgamieren, einige wenige Regisseure unbeirrt an ihrem je eigenen, persönlichen Blick auf die Welt – damit durchaus auteurs im Sinne Astrucs – festhalten, die Sehgewohnheiten des (westlichen) Zuschauers herausfordern, das Kino somit zu einem „privilegierte[n] Ort der Fremderfahrung“, zu einer „Schule der Wahrnehmung“ werden lassen.
Serial Killer – Super Hero
(2007)
Wohl kaum ein Filmgenre hat einen derartig konstanten Output wie der Serienmörder-Film. Als eines der ältesten Sujets morden sich Filmkiller konstant seit Paul Lenis Das Wachsfigurenkabinett (D 1924) durch die Filmgeschichte. Standen sie zunächst oft in Nebenhandlungen als unerkannte Verfolger, wie "Jack der Bauchaufschlitzer" im Wachsfigurenkabinett oder Jack the Ripper in Die Büchse der Pandora (D 1929) für den anthropomorphen Terror der urbanen Gesellschaft, so haben die Serienmörder über die Jahrzehnte ihr Schattendasein verlassen, sind zusehends ins Zentrum der Filmerzählungen gerückt und haben an Zuschauergunst damit stetig gewonnen. Heute ist der Serienmörder zum (Super-)Helden avanciert. Was mit dieser zugegeben recht zynischen Behauptung gemeint ist und wie es zur Glorifizierung von Mord und Mörder im Kino kommen konnte, versuche ich im Folgenden nachzuzeichnen.
Welchen Einfluss hat die Entwicklung neuer Produktions- und Darstellungstechnologien auf die Inhalte und Formate von Filmen? Wird der Kinofilm aufgrund der Entwicklung portabler Wiedergabegeräte und der Internetdisribution in spätestens fünf Jahren nicht mehr existieren? Die Frage, ob der Kinofilm, wie wir ihn derzeit kennen, in fünf Jahren noch existiert, ist nicht aus der Luft gegriffen. Sie wurde von Kees Kassander, dem Produzenten Peter Greenaways während einer Podiumsdikussion in Berlin (Berlinale Talent Campus (1): "Virtual Cinema") aufgeworfen.
Since about the year 2000 a hitherto unidentified species of the genus Leiobunum C. L. Koch, 1839, has rapidly invaded central and western Europe. Records are known from The Netherlands (probably the country of first occurrence in Europe), Germany, Austria and Switzerland. This introduced species, until now, mainly inhabits walls of buildings and rocky environments. Adults characteristically aggregate during daytime into groups of up to 1.000 individuals. The species is described and details on its present distribution, habitat preference, phenology and behaviour are presented.
Der 1997 erschienene Roman Lisa's Liebe ist der zweite Roman der österreichischen Schriftstellerin Marlene Streeruwitz. Die Protagonistin des Romans ist die 39-jährige Volksschullehrerin Lisa Liebich, deren Leben „unspektakulär zwischen Lehrberuf, peinlich lieblosen Affären und Bildungsreisen" dahin verläuft.
Arabidopsis cell walls contain large amounts of pectins and hemicelluloses, which are predominantly synthesized via the common precursor UDP-glucuronic acid. The major enzyme for the formation of this nucleotide-sugar is UDP-glucose dehydrogenase, catalysing the irreversible oxidation of UDP-glucose into UDP-glucuronic acid. Four functional gene family members and one pseudogene are present in the Arabidopsis genome, and they show distinct tissue-specific expression patterns during plant development. The analyses of reporter gene lines indicate gene expression of UDP-glucose dehydrogenases in growing tissues. The biochemical characterization of the different isoforms shows equal affinities for the cofactor NAD+ (~40 µM) but variable affinities for the substrate UDP-glucose (120–335 µM) and different catalytic constants, suggesting a regulatory role for the different isoforms in carbon partitioning between cell wall formation and sucrose synthesis as the second major UDP-glucose-consuming pathway. UDP-glucose dehydrogenase is feedback inhibited by UDP-xylose. The relatively (compared with a soybean UDP-glucose dehydrogenase) low affinity of the enzymes for the substrate UDP-glucose is paralleled by the weak inhibition of the enzymes by UDP-xylose. The four Arabidopsis UDP-glucose dehydrogenase isoforms oxidize only UDP-glucose as a substrate. Nucleotide-sugars, which are converted by similar enzymes in bacteria, are not accepted as substrates for the Arabidopsis enzymes.
