The properties of the ionic liquids were systematically varied by changing the length of the alkyl substituents on the cations, and by employing different anions such as tetrafluoroborate, hexafluorophosphate, tosylate, triflate, alkyl sulfates and dimethyl phosphate. Results were compared to analogous polymerizations in toluene and in bulk. The solvents have no detectable influence on polymer tacticity. However, the molar masses obtained and the degree of polymerization, respectively, are very sensitive to the choice of the solvent. The degrees of polymerization are significantly higher when polymerizations were carried out in ionic liquids compared to polymerization in toluene, and can even exceed the values obtained by bulk polymerization. Imidazolium salts unsubstituted at C-2 result in an increase in the degree of polymerization of the poly(butyl methacrylate) with increasing viscosity of these ionic liquids. Methyl substitution at C-2 of the imidazolium ion results in an increase in the viscosity of the ionic liquid and in a viscosity independent degree of polymerization of the poly(butyl methacrylate). Ionic liquids based on imidazolium salts seem preferable over pyridinium and alkylammonium salts because of the higher degree of polymerization of the poly(butyl methacrylate)s obtained in the imidazolium salts.

Strong excitonic interactions between peridinins, as well as between peridinins and chlorophylls (Chls) a, can be expected from the short intermolecular distances revealed by the crystal structure. Different experimental approaches of nonlinear polarization spectroscopy in the frequency domain (NLPF) were used to investigate the various interactions between pigments in PCP of Amphidinium carterae at room temperature. Lineshapes of NLPF spectra indicate strong excitonic interactions between the peridinin's optically allowed S-2 (1Bu(+)) states. A comprehensive subband analysis of the distinct NLPF spectral substructure in the peridinin region allows us to assign peridinin subbands to the two Chls a in PCP having different S-1-state lifetimes. Peridinin subbands at 487, 501, and 535 nm were assigned to the longer-lived Chl, whereas a peridinin subband peaking at 515 nm was detected in both clusters. Certain peridinin(s), obviously corresponding to the subband centered at 487 nm, show(s) specific (possibly Coulombic?) interaction between the optically dark S-1(2A(g)(-)) and/or intramolecular charge- transfer (ICT) state and S-1 of Chl a. The NLPF spectrum, hence, indicates that this peridinin state is approximately isoenergetic or slightly above S-1 of Chl a. A global subband analysis of absorption and NLPF spectra reveals that the Chl a Q(y)-band consists of two subbands ( peaking at 669 and 675 nm and having different lifetimes), confirmed by NLPF spectra recorded at high pump intensities. At the highest applied pump intensities an additional band centered at <= 660 nm appears, suggesting-together with the above results-an assignment to a low-dipole moment S-0-> S-1/ICT transition of peridinin}, language = {en} } @phdthesis{Heller2006, author = {Heller, Wilfried}, title = {Heller, W., The 'Bohemians' in New Zealand : an ethnik group?; Auckland, Univ., 2005}, year = {2006}, language = {en} } @article{RaynaudJondNecandMarcilhacetal.2006, author = {Raynaud, F and Jond-Necand, C and Marcilhac, Anne and F{\"u}rst, Dieter Oswald and Benyamin, Yves}, title = {Calpain 1-gamma filamin interaction in muscle cells : a possible in situ regulation by PKC-alpha}, year = {2006}, language = {en} } @book{FanselowFerySchlesewskyetal.2006, author = {Fanselow, Gisbert and F{\´e}ry, Caroline and Schlesewsky, Matthias and Vogel, Ralf}, title = {Gradience in grammar : generative perspectives}, publisher = {Oxford University Press}, address = {Oxford, New York}, isbn = {0-19-927479-7}, pages = {416 S.}, year = {2006}, language = {en} } @article{Fery2006, author = {F{\´e}ry, Caroline}, title = {Gradient Perception of Intonation}, isbn = {0-19-927479-7}, year = {2006}, language = {en} } @article{AndresenGronau2006, author = {Andresen, Katja and Gronau, Norbert}, title = {Managing Change : determining the adaptability of information systems}, year = {2006}, language = {en} } @book{HuettenrauchKylauGrundetal.2006, author = {H{\"u}ttenrauch, Stefan and Kylau, Uwe and Grund, Martin and Queck, Tobias and Ploskonos, Anna and Schreiter, Torben and Breest, Martin and Haubrock, S{\"o}ren and Bouche, Paul}, title = {Fundamentals of Service-Oriented Engineering}, series = {Technische Berichte des Hasso-Plattner-Instituts f{\"u}r Softwaresystemtechnik an der Universit{\"a}t Potsdam}, volume = {18}, journal = {Technische Berichte des Hasso-Plattner-Instituts f{\"u}r Softwaresystemtechnik an der Universit{\"a}t Potsdam}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {3-939469-35-1}, issn = {1613-5652}, year = {2006}, language = {en} } @article{ZenBilgeGalbrechtetal.2006, author = {Zen, Achmad and Bilge, Askin and Galbrecht, Frank and Alle, Ronald and Meerholz, Klaus and Grenzer, J{\"o}rg and Neher, Dieter and Scherf, Ullrich and Farrell, Tony}, title = {Solution processable organic field-effect transistors utilizing an alpha,alpha '-dihexylpentathiophene- based swivel cruciform}, doi = {10.1021/Ja0573357}, year = {2006}, language = {en} } @article{HarlovJohanssonVanDenKerkhofetal.2006, author = {Harlov, Daniel E. and Johansson, L. and Van Den Kerkhof, A. and F{\"o}rster, Hans-J{\"u}rgen}, title = {The role of advective fluid flow and diffusion during localized, solid-state dehydration : Sondrum Stenhuggeriet, Halmstad, SW Sweden}, issn = {0022-3530}, year = {2006}, abstract = {A localized dehydration zone, Sondrum stone quarry, Halmstad, SW Sweden, consists of a central, 1 m wide granitic pegmatoid dyke, on either side of which extends a 2.5-3 m wide dehydration zone (650-700 degrees C; 800 MPa; orthopyroxene-clinopyroxene-biotite-amphibole-garnet) overprinting a local migmatized granitic gneiss (amphibole-biotite- garnet). Whole-rock chemistry indicates that dehydration of the granitic gneiss was predominantly isochemical. Exceptions include [Y + heavy rare earth elements (HREE)], Ba, Sr, and F, which are markedly depleted throughout the dehydration zone. Systematic trends in the silicate and fluorapatite mineral chemistry across the dehydration zone include depletion in Fe, (Y + HREE), Na, K, F, and Cl, and enrichment in Mg, Mn, Ca, and Ti. Fluid inclusion chemistry is similar in all three zones and indicates the presence of a fluid containing CO2, NaCl, and H2O components. Water activities in the dehydration zone average 0.36, or XH2O = 0.25. All lines of evidence suggest that the formation of the dehydration zone was due to advective transport of a CO2-rich fluid with a minor NaCl brine component originating from a tectonic fracture. Fluid infiltration resulted in the localized partial breakdown of biotite and amphiboles to pyroxenes releasing Ti and Ca, which were partitioned into the remaining biotite and amphibole, as well as uniform depletion in (Y + HREE), Ba, Sr, Cl, and F. At some later stage, H2O-rich fluids (H2O activity > 0.8) gave rise to localized partial melting and the probable injection of a granitic melt into the tectonic fracture, which resulted in the biotite and amphibole recording a diffusion profile for F across the dehydration zone into the granitic gneiss as well as a diffusion profile in Fe, Mn, and Mg for all Fe-Mg silicate minerals within 100 cm of the pegmatoid dyke}, language = {en} } @article{KlinkaBalentovaBernatetal.2006, author = {Klinka, Karel D. and Balentova, Eva and Bern{\´a}t, Juraj and Imrich, J{\´a}n and Vavrusov{\´a}, Martina and Pihlaja, Kalevi and Koch, Andreas and Kleinpeter, Erich and Kelling, Alexandra and Schilde, Uwe}, title = {Structural revision of products resulting from the reaction of methylhydrazine with acridin-9-yl isothiocyanate due to unexpected acridinyl migration And further reactions}, issn = {1551-7004}, year = {2006}, abstract = {The reaction of methyl acridin-9-ylthiosemicarbazide under basic conditions with methyl bromoacetate resulted in a 1,3-thiazolin-4-one structure as provided by X-ray crystallography.

In the honeybee (Apis mellifera), cAMP-dependent signal transduction has been implicated in behavioural processes as well as in learning and memory. Key components of cAMP-signalling cascades are adenylyl cyclases. However, the molecular identities and biochemical properties of adenylyl cyclases are completely unknown in the honeybee. We have cloned a cDNA (Amac3) from honeybee brain that encodes a membrane-bound adenylyl cyclase. The Amac3 gene is an orthologue of the Drosophila ac39E gene. The corresponding proteins share an overall amino acid similarity of approximately 62\%. Phylogenetically, AmAC3 belongs to group 1 adenylyl cyclases. Heterologously expressed AmAC3 displays basal enzymatic activity and efficient coupling to endogenous G protein signalling pathways. Stimulation of beta-adrenergic receptors induces AmAC3 activity with an EC50 of about 3.1 mu m. Enzymatic activity is also increased by forskolin (EC50 approximately 15 mu m), a specific agonist of membrane-bound adenylyl cyclases. Similar to certain biogenic amine receptor genes of the honeybee, Amac3 transcripts are expressed in many somata of the brain, especially in mushroom body neurones. These results suggest that the enzyme serves in biogenic amine signal transduction cascades and in higher brain functions that contribute to learning and memory of the bee}, language = {en} } @article{LeitererLeitenbergerEmmerlingetal.2006, author = {Leiterer, York and Leitenberger, Wolfram and Emmerling, Franziska and Th{\"u}nemann, Andreas F. and Panne, Ulrich}, title = {The use of an acoustic levitator to follow crystallization in small droplets by energydispersive X-ray diffraction}, issn = {0021-8898}, doi = {10.1107/S0021889806024915}, year = {2006}, language = {en} } @article{Kleinpeter2006, author = {Kleinpeter, Erich}, title = {Push-pull alkenes : structure and pi-electron distribution}, doi = {10.2298/Jsc0601001k}, year = {2006}, abstract = {Push-pull alkenes are substituted alkenes with one or two electron-donating substituents on one end of C=C double bond and with one or two electron-accepting substituents at the other end. Allowance for pi-electron delocalization leads to the central C=C double bond becoming ever more polarized and with rising push-pull character, the pi-bond order of this double bond is reduced and, conversely, the corresponding pi-bond orders of the C-Don and C- Ace bonds are accordingly increased. This push-pull effect is of decisive influence on both the dynamic behavior and the chemical reactivity of this class of compounds and thus it is Of Considerable interest to both determine and to quantify the inherent push-pull effect. previously, the barriers to rotation about the C=C, C-Don and/or C-Acc partial double bonds (Delta G(not equal), as determined by dynamic NMR spectroscopy) or the C-13 chemical shift difference of the polarized C=C partial double bond (Delta delta(C=C)) were employed for this purpose, However, these parameters can have serious limitations, viz. the barriers can be immeasurable on the NMR timescale (either by being too high or too low-, heavily-biased conformers are present, etc.) or Delta delta(C=C) behaves in a non-additive manner with respect to the combination of the four substituents. Hence, a general parameter to quantify the push-pull effect is not yet available. Ab initio MO calculations on a collection of compounds, together with NBO analysis, provided valuable information on the structure, bond energies, electron occupancies and bonding/antibonding interactions. In addition to Delta G(C=C)(not equal) (either experimentally determined or theoretically calculated) and Delta delta(C=C), the bond length of the C=C partial double bond was also examined and it proved to be a reliable parameter to quantify the push-pull effect. Equally so, the quotient of the occupation numbers of the antibonding and bonding pi orbitals of the central C=C partial double bond ( pi*(C=C)/pi(C=C) ) could also be employed for this purpose}, language = {en} } @article{NabelekLabotkaHelmsetal.2006, author = {Nabelek, Peter I. and Labotka, Theodore C. and Helms, Thomas S. and Wilke, Max}, title = {Fluid-mediated polymetamorphism related to proterozoic collision of Archean Wyoming and Superior Provinces in the Black Hills, South Dakota}, year = {2006}, language = {en} } @article{HuggenbergerRidgwayOelschlageretal.2006, author = {Huggenberger, Stefan and Ridgway, Sam H. and Oelschlager, Helmut H.A. and Kirschenbauer, Irmgard and Vogl, Thomas J. and Klima, Milan}, title = {Histological analysis of the nasal roof cartilage in a neonate sperm whale (Physeter macrocephalus : Mammalia, Odontoceti)}, issn = {0044-5231}, doi = {10.1016/j.jcz.2006.01.001}, year = {2006}, abstract = {The nasal roof cartilage of a neonate sperm whale (Physeter macrocephalus) was examined by gross dissection and routine histology. This cartilage is part of the embryonic Tectum nasi and is a critical feature in the formation of the massive sperm whale forehead. In neonates as well as in adults, the blade-like nasal roof cartilage extends diagonally through the huge nasal complex from the bony nares to the blowhole on the left side of the rostral apex of the head. It accompanies the left nasal passage along its entire length, which may reach several meters in adult males. The tissue of the nasal roof cartilage in the neonate whale shows an intermediate state of development. For example, in embryos and fetuses, the nasal roof cartilage consists of hyaline cartilage, but in adult sperm whales, it also includes elastic fibers. In our neonate sperm whale, the nasal roof cartilage already consisted of adult-like elastic cartilage. In addition, the active or growing, layer of the perichondrium was relatively thick compared to that of fetuses, and a large number of straight, elastic fibers that were arranged perpendicularly to the long axis of the nasal roof cartilage were present. These neonatal features call be interpreted as characteristics of immature and growing cartilaginous tissue. An important function of the nasal roof cartilage may be the stabilization of the left nasal passage, which is embedded within the soft tissue of the nasal complex. The nasal roof cartilage with its elastic fibers may keep the nasal passage open and prevent its collapse from Bernoulli forces during inhalation. Additionally, the intrinsic tension of the massive nasal musculature may be a source of compression on the nasal roof cartilage and could explain its hyaline character in the adult. In our neonate specimen, in contrast, the cartilaginous rostrum (i.e., mesorostral cartilage) consisted of hyaline cartilage with an ample blood supply. The cartilaginous rostrum does not change its histological characteristics during development, but its function In adults is still not understood.}, language = {en} } @book{BenRafaelJasperHarris2006, author = {Ben-Rafael, Eliezer and Jasper, Willi and Harris, Paul}, title = {Building a diaspora : Russian Jews in Israel, Germany and the USA}, volume = {13}, publisher = {Brill}, address = {Leiden}, isbn = {978-90-04-15332-5}, pages = {374 S.}, year = {2006}, language = {en} } @phdthesis{Maulbetsch2006, author = {Maulbetsch, Christian}, title = {Modeling galaxy formation in different environments}, address = {Potsdam}, pages = {IV, 138 S. : graph.

The probability of rainfall on a given day of the year is described by a regular Gaussian peak curve function. The amount of rain is drawn randomly from an exponential distribution whose mean is the daily mean rain amount (averaged across years for each day of the year) described by a flattened Gaussian peak curve. Parameters for the curves have been calculated from monthly aggregated, long-term rain records from seven meteorological stations. Parameters for arbitrary points on the MAP gradient are calculated from a regression equation with MAP as the only independent variable. The simple structure of the generator allows it to produce time series with daily rain patterns that are projected under climate change scenarios and simultaneously control MAP. Increasing within-year variability of daily precipitation amounts also increases among-year variability of MAP as predicted by global circulation models.

In a recent study, we observed the presence of calpain I in the muscle contractile apparatus and specifically in the N1- and N2-fines. This calpain isoform was found to be involved in the degradation of muscle fibres via proteolysis of key proteins in Z-disk and costameric junctions. The goal of this study was to determine whether gamma-filamin - a specific muscle isoform of the filamin family - is a calpain, I substrate and to characterise this interaction. gamma-Filamin is a major muscle architectural protein located in the Z-fine and under the sarcolemmal membrane. This protein is a component of the chain binding the sarcolemma to the sarcomeric structure. In this study, we found that gamma-filamin formed a stable complex in vitro and in cells with calpain I in the absence of calcium stimulation. We also located the binding domains in the C-terminus of gamma-filamin with a cleavage site between serine 2626 and serine 2627 in the hinge 2 region. The catalytic (80 kDa) and regulatory (28 kDa) subunits of calpain I are both involved in high affinity binding at gamma-filamin. Moreover, we showed that phosphorylation of the filamin C- terminus domain by PKC alpha protected gamma-filamin against proteolysis by calpain I in COS cells.
