The microtubules possess an intrinsic direction, having a 'plus' and a 'minus' end. Some molecular motors such as cytoplasmic dynein walk to the minus end, while others such as conventional kinesin walk to the plus end. Cells typically have an isopolar microtubule network. This is most pronounced in neuronal axons or fungal hyphae. In these long and thin tubular protrusions, the microtubules are arranged parallel to the tube axis with the minus ends pointing to the cell body and the plus ends pointing to the tip. In such a tubular compartment, transport by only one motor type leads to 'motor traffic jams'. Kinesin-driven cargos accumulate at the tip, while dynein-driven cargos accumulate near the cell body. We identify the relevant length scales and characterize the jamming behaviour in these tube geometries by using both Monte Carlo simulations and analytical calculations. A possible solution to this jamming problem is to transport cargos with a team of plus and a team of minus motors simultaneously, so that they can travel bidirectionally, as observed in cells. The presumably simplest mechanism for such bidirectional transport is provided by a 'tug-of-war' between the two motor teams which is governed by mechanical motor interactions only. We develop a stochastic tug-of-war model and study it with numerical and analytical calculations. We find a surprisingly complex cooperative motility behaviour.

Jahrhunderts sehr erfolgreich waren. Der Roman beschreibt das Leben franz{\"o}sischer Kriegsgefangener in einem holsteinischen Dorf w{\"a}hrend des Ersten Weltkriegs und ist das fiktionale Pendant zu den Kriegserinnerungen von F.E. Peters, der selbst von 1914 bis 1920 Gefangener in Frankreich war und dort als Dolmetscher eingesetzt wurde. Im Mittelpunkt der Handlung steht die junge Elisabeth Torm{\"a}hlen, die sich von der weltfremden Sch{\"u}lerin eines M{\"a}dchenpensionats zu einer t{\"u}chtigen B{\"a}uerin und reifen Ehefrau entwickelt. W{\"a}hrend ihr Mann an der Front ist, entspinnt sich eine kurze harmlose Romanze zwischen ihr und dem franz{\"o}sischen Dolmetscher Gaston Marzais, die schnell beendet ist, als Elisabeth endg{\"u}ltig zu ihrem Mann findet und dieser sich nach Kriegsende von ihrer Treue {\"u}berzeugen kann. Das vielschichtige Werk beschreibt unter Verzicht auf die g{\"a}ngigen nationalen Stereotypen oder mittels deren Demontage Deutsche und Franzosen als in ihrer Unterschiedlichkeit sehr {\"a}hnlich. Durch zahlreiche Symmetrie-Effekte und konsequent durchgef{\"u}hrte Perspektivwechsel, die sowohl die deutsche als auch die franz{\"o}sische Sicht zu ber{\"u}cksichtigen suchen, wird das Gleiche im Fremden hervorgehoben. Gleicher Patriotismus und gleiche Opferbereitschaft auf beiden Seiten, aber auch gleiche Friedenssehns{\"u}chte und gleiches Leiden unter den Grausamkeiten des Krieges sowie gleiche fachliche Kompetenz - denn auch die gefangenen Franzosen sind erfahrene Bauern und bew{\"a}hren sich im t{\"a}glichen Zusammenleben. Fanatiker wie die verbitterte Soldatenwitwe Greta Harders oder der hasserf{\"u}llte Brandstifter Maurice Thaudi{\`e}re werden als lebensunt{\"u}chtig dargestellt und begehen Selbstmord. Den ideologischen Grundtenor des Werkes betonen zum Schluss noch einmal die Intellektuellen: Gaston Marzais und sein deutscher Freund, der Jurist Georg Schmitt, beide erf{\"u}llt von dem Wissen um und dem Respekt vor der Kultur des anderen. Gemeinsam wollen sie nach der deutschen Niederlage weitere deutsch-franz{\"o}sische Kriege verhindern und beschw{\"o}ren die pazifistische Vision eines Europas der Toleranz und der Aufkl{\"a}rung. „Der heilsame Umweg" ist dar{\"u}ber hinaus eine Hymne an b{\"a}uerliche Kultur und famili{\"a}re Werte. So bewundert Marzais Interieur und Kleidung der alten B{\"a}uerin Abel Schierholdt. Auch ein traditionelles norddeutsches Begr{\"a}bnisritual wird detailliert beschrieben. Frankreichs Landleben ist pr{\"a}sent durch nostalgische Evozierungen der Gefangenen und deutliche Ankl{\"a}nge an den am Anfang des letzten Jahrhunderts sehr beliebten Roman von Henry Bordeaux „Les Roquevillard" (1906), den F.E.Peters w{\"a}hrend seiner Kriegsgefangenschaft {\"u}bersetzt hat. Schließlich reflektiert der Roman Macht und Ohnmacht von Sprache sowie die autobiographische Dimension literarischer Produktions- und Rezeptionsprozesse.

Most bilingual programs in German secondary education started out by focusing on subjects from the field of social sciences.

And though one cannot deny the gain that ensues from an intercultural perspective on subjects such as history or geography, this benefit is certainly not limited to social science subjects. In consequence, bilingual curriculum designers have already begun to include other subjects such as physics or chemistry in bilingual school programs.

To assess current and future developments, it is crucial to understand past environmental dynamics in these landscapes. Causes and interactions of environmental variability can hardly be resolved by instrumental records covering modern time scales. However, long-term environmental variability is recorded in paleoenvironmental archives. Lake sediments are important archives that allow reconstruction of local limnogeological processes as well as past environmental changes driven directly or indirectly by climate dynamics. This study aims at reconstructing Late Quaternary permafrost and thermokarst dynamics in central-eastern Beringia, the terrestrial land mass connecting Eurasia and North America during glacial sea-level low stands. In order to investigate development, processes and influence of thermokarst dynamics, several sediment cores from extant lakes and drained lake basins were analyzed to answer the following research questions: 1. When did permafrost degradation and thermokarst lake development take place and what were enhancing and inhibiting environmental factors? 2. What are the dominant processes during thermokarst lake development and how are they reflected in proxy records? 3. How did, and still do, thermokarst dynamics contribute to the inventory and properties of organic matter in sediments and the carbon cycle? Methods applied in this study are based upon a multi-proxy approach combining sedimentological, geochemical, geochronological, and micropaleontological analyses, as well as analyses of stable isotopes and hydrochemistry of pore-water and ice. Modern field observations of water quality and basin morphometrics complete the environmental investigations. The investigated sediment cores reveal permafrost degradation and thermokarst dynamics on different time scales. The analysis of a sediment core from GG basin on the northern Seward Peninsula (Alaska) shows prevalent terrestrial accumulation of yedoma throughout the Early to Mid Wisconsin with intermediate wet conditions at around 44.5 to 41.5 ka BP. This first wetland development was terminated by the accumulation of a 1-meter-thick airfall tephra most likely originating from the South Killeak Maar eruption at 42 ka BP. A depositional hiatus between 22.5 and 0.23 ka BP may indicate thermokarst lake formation in the surrounding of the site which forms a yedoma upland till today. The thermokarst lake forming GG basin initiated 230 ± 30 cal a BP and drained in Spring 2005 AD. Four years after drainage the lake talik was still unfrozen below 268 cm depth. A permafrost core from Mama Rhonda basin on the northern Seward Peninsula preserved a full lacustrine record including several lake phases. The first lake generation developed at 11.8 cal ka BP during the Lateglacial-Early Holocene transition; its old basin (Grandma Rhonda) is still partially preserved at the southern margin of the study basin. Around 9.0 cal ka BP a shallow and more dynamic thermokarst lake developed with actively eroding shorelines and potentially intermediate shallow water or wetland phases (Mama Rhonda). Mama Rhonda lake drainage at 1.1 cal ka BP was followed by gradual accumulation of terrestrial peat and top-down refreezing of the lake talik. A significant lower organic carbon content was measured in Grandma Rhonda deposits (mean TOC of 2.5 wt\%) than in Mama Rhonda deposits (mean TOC of 7.9 wt\%) highlighting the impact of thermokarst dynamics on biogeochemical cycling in different lake generations by thawing and mobilization of organic carbon into the lake system. Proximal and distal sediment cores from Peatball Lake on the Arctic Coastal Plain of Alaska revealed young thermokarst dynamics since about 1,400 years along a depositional gradient based on reconstructions from shoreline expansion rates and absolute dating results. After its initiation as a remnant pond of a previous drained lake basin, a rapidly deepening lake with increasing oxygenation of the water column is evident from laminated sediments, and higher Fe/Ti and Fe/S ratios in the sediment. The sediment record archived characterizing shifts in depositional regimes and sediment sources from upland deposits and re-deposited sediments from drained thaw lake basins depending on the gradually changing shoreline configuration. These changes are evident from alternating organic inputs into the lake system which highlights the potential for thermokarst lakes to recycle old carbon from degrading permafrost deposits of its catchment. The lake sediment record from Herschel Island in the Yukon (Canada) covers the full Holocene period. After its initiation as a thermokarst lake at 11.7 cal ka BP and intense thermokarst activity until 10.0 cal ka BP, the steady sedimentation was interrupted by a depositional hiatus at 1.6 cal ka BP which likely resulted from lake drainage or allochthonous slumping due to collapsing shore lines. The specific setting of the lake on a push moraine composed of marine deposits is reflected in the sedimentary record. Freshening of the maturing lake is indicated by decreasing electrical conductivity in pore-water. Alternation of marine to freshwater ostracods and foraminifera confirms decreasing salinity as well but also reflects episodical re-deposition of allochthonous marine sediments. Based on permafrost and lacustrine sediment records, this thesis shows examples of the Late Quaternary evolution of typical Arctic permafrost landscapes in central-eastern Beringia and the complex interaction of local disturbance processes, regional environmental dynamics and global climate patterns. This study confirms that thermokarst lakes are important agents of organic matter recycling in complex and continuously changing landscapes.}, language = {en} } @phdthesis{Frenzel2015, author = {Frenzel, Sabine}, title = {Die Rolle der Umamirezeptoruntereinheit Tas1r1 jenseits ihrer gustatorischen Bedeutung}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-79502}, school = {Universit{\"a}t Potsdam}, pages = {XV, 172}, year = {2015}, abstract = {Aminos{\"a}uren sind lebensnotwendige Molek{\"u}le f{\"u}r alle Organismen.

W{\"a}hrend sich Ern{\"a}hrungsverhalten, Gesamtphysiologie, Gewebemorphologie sowie Futterverdaulichkeit unver{\"a}ndert zeigten, war die renale Stickstoffausscheidung bei Tas1r1-Knockout-M{\"a}usen auf eiweißarmer sowie auf eiweißreicher Di{\"a}t signifikant verringert. Eine {\"U}berdeckung der Auswirkungen des Tas1r1-Knockouts aufgrund kompensatorischer Effekte durch den Aminos{\"a}uresensor CaSR oder den Peptidsensor Gpr93 war nicht nachweisbar. Es bleibt offen, ob andere Mechanismen oder andere Chemosensoren an einer Kompensation beteiligt sind oder aber Tas1r1 in extraoralem Gewebe andere Funktionen als die der Aminos{\"a}uredetektion {\"u}bernimmt. Unterschiede im extraoralen Expressionsmuster der beiden Umamirezeptor-untereinheiten Tas1r1 und Tasr3 lassen Spekulationen {\"u}ber andere Partner, Liganden und Funktionen zu.}, language = {de} }
