N2 - Theoretische Ansätze unter den Oberbegriffen "Hierarchy" und "Scale" sind in der Ökologie seit den 1980er-Jahren entwickelt und intensiv diskutiert worden. Das wissenschaftliche Paradigma kann mit dem Begriff "Hierarchical Patch Dynamics" beschrieben werden. Obwohl auch Anwendungsbezüge diskutiert und konzipiert wurden, hat es in Deutschland bisher in der Landschaftsplanung kein größeres Echo hervorgerufen. Gleichwohl gibt es eine Reihe interessanter Anknüpfungspunkte zwischen Aussagen der ökologischen Hierarchie-Theorie und konkreten landschaftsplanerischen und naturschutzfachliceh Aufgabenstellungen. Vor diesem Hintergrund werden Grundzüge dieser Theorie bzw. der unter dem Dach des Paradigmas "Hierarchical Patch Dynamics" versammelten theoretischen Ansätze dargestellt. Wesentlich ist die erkenntnistheoretische Grundhaltung, die versucht, unzulässige Verallgemeinerungen oder Absolutheitsansprüche auszuschließen, indem sie zunächst den Gegenstandsbereich der Ökologie beschreibt und analysiert. Auf dieser Grundlage werden Herangehensweisen zur Behandlung ökologischer Fragestellungen vorgeschlagen. Diese Herangehensweisen lassen sich auf landschaftsplanerische Aufgaben übertragen. Es wird gezeigt, für welche Bereiche eine solche Übertragung denkbar wäre. Letztlich bedürfte es einer Praxisüberprüfung, um herauszufinden, ob mit Hilfe von Ansätzen der ökologischen Hierarchie- Theorie die Bearbeitung planerischer Fragestellungen verbessert oder ergänzt werden könnte.

Recent experiments have found that trap lifetimes get reduced when approaching the substrate because atoms couple to thermally excited near fields. The data agree quantitatively with our theory [Appl. Phys. B 69, 379 (1999)]. We focus on the decoherence of a quantum degenerate gas in a quasi-one-dimensional trap. Monte Carlo simulations indicate that atom interactions reduce the condensate decoherence rate. This is explained by a simple theory in terms of the suppression of long-wavelength excitations.

Let k greater than or equal to 1 be a natural number. An identity s approximate to t of type tau is called k- normal if either s = t or both s and t have value greater than or equal to k, and otherwise is called non-k-normal. A variety V of type tau is said to be k-normal if all its identities are k-normal, and non-k-normal otherwise. In the latter case, there is a unique smallest k-normal variety N-k(A) (V) to contain V , called the k-normalization of V. Inthe case k = 1, for the usual depth valuation of terms, these notions coincide with the well-known concepts of normal identity, normal variety, and normalization of a variety. I. Chajda has characterized the normalization of a variety by means of choice algebras. In this paper we generalize his results to a characterization of the k-normalization of a variety, using k-choice algebras. We also introduce the concept of a k-inflation algebra, and for the case that v is the usual depth valuation of terms, we prove that a variety V is k-normal iff it is closed under the formation of k- inflations, and that the k-normalization of V consists precisely of all homomorphic images of k-inflations of algebras in V Y1 - 2004 SN - 0002-5240 ER - TY - JOUR A1 - Delgrande, James Patrick A1 - Schaub, Torsten H.

A set of criteria for classifying approaches is given, followed by a set of desiderata that an approach might be expected to satisfy.

A1 - Jeltsch, Florian T1 - A conceptual model linking demography of the shrub species Grewia flava to the dynamics of Kalahari savannas N2 - Environmental heterogeneity is a major determinant of plant population dynamics. In semi-arid Kalahari savannas, heterogeneity is created by savanna structure, i.e. by the spatial arrangement and temporal dynamics of woody plant and open grassland microsites. We formulate a conceptual model describing the effects of savanna dynamics on the population dynamics of the animal-dispersed shrub Grewia flava. From empirical results we derive model rules describing effects of savanna structure on several processes in Grewia's life cycle. By formulating the model, we summarise existing information on Grewia demography and identify gaps in this knowledge. Despite a number of such gaps, the model can be used to make certain quantitative predictions. As an example, we apply the model to investigate the role of seed dispersal in Grewia encroachment on rangelands. Model results show that cattle promote encroachment by depositing substantial numbers of seeds in open areas, where Grewia is otherwise dispersal-limited. Finally, we draw some general conclusions about Grewia's life history and population dynamics. Under natural conditions, concentrated seed deposition under woody plants appears to be a key process causing the observed association between Grewia and other woody plants. Furthermore, low rates of recruitment and high adult survival result in slow-motion dynamics of Grewia populations. As a consequence, Grewia populations interact with savanna dynamics on long temporal and short to intermediate spatial scales. Y1 - 2004 ER - TY - BOOK A1 - Gauthier, P. M.

The algorithm is based on the Frobenius-norm formulation of the joint diagonalization problem, and addresses diagonalization with a general, non- orthogonal transformation. The iterative scheme of the algorithm is based on a multiplicative update which ensures the invertibility of the diagonalizer. The algorithm's efficiency stems from the special approximation of the cost function resulting in a sparse, block-diagonal Hessian to be used in the computation of the quasi-Newton update step. Extensive numerical simulations illustrate the performance of the algorithm and provide a comparison to other leading diagonalization methods. The results of such comparison demonstrate that the proposed algorithm is a viable alternative to existing state-of-the-art joint diagonalization algorithms. The practical use of our algorithm is shown for blind source separation problems Y1 - 2004 ER - TY - JOUR A1 - Pena, M. A1 - Hamann, Wolf-Rainer A1 - Ruiz, M. T. A1 - Peimbert, A. A1 - Peimbert, M. T1 - A high resolution spectroscopic study of the extraordinary planetary nebula LMC-N66 N2 - The planetary nebula N66 in the Large Magellanic Cloud is an extraordinary object, as it is the only confirmed PN where the central star is a Wolf-Rayet star of the nitrogen sequence, i.e. of type [WN]. Moreover, the star showed a dramatic brightness outburst in 1993-1994. In a previous paper (Hamann et al. 2003) we analyzed the changing stellar spectra and found evidence that the central star is most likely a binary system where a white dwarf presently accretes matter from a non-degenerate companion at a high rate. Thus the object is a candidate for a future type Ia supernova in our cosmic neighborhood. In the present paper we analyze the morphology and kinematics of the nebula, using images and high-resolution spectra obtained with the Hubble Space Telescope (HST) and the Very Large Telescope (ESO-VLT). The object presents a complex multipolar structure, dominated by very bright lobes located at both sides of the central star and separated by a narrow waist. In addition there is a pair of very extended and twisted loops, also pointing in opposite directions; their symmetry axis and collimation angle differs from those of the bright lobes. High resolution spectroscopy reveals two main velocity components, "approaching" material at an average heliocentric radial velocity Of V-rad = 248 30 km s(-1) and similarly bright "receding" material at V-rad = 331 +/- 25 km s(-1). A systemic velocity of about 300 km s(-1) is derived. Opposite lobes and loops possess opposite velocities. Furthermore there are knots and filaments of complex structure and kinematics. Close to the central star, nebular gas is found, receding at very high velocity (125 km s(-1) relative to the system). The morphology and kinematics of LMC-N66 can be explained as the result of episodic bipolar ejections with changing axis. The bipolar structures could have been produced by collimated streams ejected from a precessing central source. We suggest that the precession could have been produced by an external torque, possibly due to a binary companion. Young, fast-moving nebular knots close to the star appear slightly He- and N-richer than the main body of the nebula, but are still hydrogen-rich in contrast to the helium-dominated atmosphere of the [WN]- type central star. In the binary scenario, this nebular matter must have been accreted from the non-degenerate companion and re-ejected before it was fully burnt Y1 - 2004 ER - TY - JOUR A1 - Kühnel, Dana A1 - Steinberg, Pablo A1 - Scholtka, Bettina T1 - A human-relevant dose of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PHIP) can induce precancerous lesions in rat intestine after 6 months of exposure Y1 - 2004 SN - 0028-1298 ER - TY - JOUR A1 - Kress, H.

The Kil-1 gene is expressed exclusively in prepupal salivary glands. Using a size mutant of the KIL-1 protein and MALDI-TOF analysis, we demonstrate that during pupation this protein is released from the prepupal salivary glands into the pupation fluid covering the surface of the pupa. 3-D- structure predictions are consistent with the known crystal structure of the human Kunitz type protease inhibitor 2KNT. This is the first experimental proof for the extra-corporal presence of a distinct Drosophila prepupal salivary gland protein. Possible functions of KIL-1 in the context of the control of proteolytic activities in the pupation fluid are discussed. (C) 2004 Elsevier Ltd.

Starting from an electron-donating and an electron-accepting polyfluorene derivative, PFB and F8BT, dissolved in suitable organic solvents, dispersions of solid particles with mean diameters of ca. 50 nm, containing either the pure polymer components or a mixture of PFB and F8BT in each particle, were prepared with the miniemulsion process. Photovoltaic devices based on these particles have been studied with respect to the correlation between external quantum efficiency and layer composition. It is shown that the properties of devices containing a blend of single-component PFB and F8BT particles differ significantly from those of solar cells based on blend particles, even for the same layer composition. Various factors determining the quantum efficiency in both kinds of devices are identified and discussed, taking into account the spectroscopic properties of the particles. An external quantum efficiency of ca. 4% is measured for a device made from polymer blend nanoparticles containing PFB:F8BT at a weight ratio of 1:2 in each individual nanosphere.

The European and Adriatic Mohos (EM and AM, respectively) are clearly imaged with different seismic techniques: near-vertical incidence reflections and receiver functions (RFs). The European Moho dips gently southward from 35 km beneath the northern foreland to a maximum depth of 55 km beneath the central part of the Eastern Alps, whereas the Adriatic Moho is imaged primarily by receiver functions at a relatively constant depth of about 40 km. In both data sets, we have also detected first-order Alpine shear zones, such as the Helvetic detachment, Inntal fault and SubTauern ramp in the north. Apart from the Valsugana thrust, receiver functions in the southern part of the Eastern Alps have also observed a north dipping interface, which may penetrate the entire Adriatic crust [Adriatic Crust Interface (ACI)]. Deep crustal seismicity may be related to the ACI. We interpret the ACI as the currently active retroshear zone in the doubly vergent Alpine collisional belt. (C) 2004 Elsevier B.V.

T1 - A new graphical presentation and subdivision of potassium micas N2 - A system based on variation of the octahedrally coordinated cations is proposed for graphical presentation and subdivision of tri- and dioctahedral K micas, which makes use of elemental differences (in a.p.f.u.): (Mg - Li) [= mgli] and (Fe-tot + Mn + Ti - Al-VI) [= feal]. All common true tri- and dioctahedral K micas are shown in a single polygon outlined by seven main compositional points forming its vertices. Sequentially clockwise, starting from Mg-3 (phlogopite), these points are: Mg2.5Al0.5, Al(2.167)square(0.833), Al1.75Li1.25, Li2Al (polylithionite), Fe22+Li, and Fe-3(2+) (annite). Trilithionite (Li1.5Al1.5), Li1.5Fe2+Al0.5, Fe22+Mg, and Mg2Fe2+ are also located on the perimeter of the polygon. IMA-siderophyllite (Fe22+Al) and muscovite (Al(2)square) plot inside. The classification conforms with the IMA-approved mica nomenclature and differentiates among the following mica species according to their position in a diagram consisting of nigh and feal axes plotted orthogonally; trioctahedral: phlogopite, biotite, siderophyllite, annite, zinnwaldite, lepidolite and tainiolite: dioctahedral: muscovite, phengite and celadonite. Potassium micas with [Si] <2.5 a.p.f.u. including IMA-siderophyllite, KFe22+AlAl2Si2O10(OH)(2), and IMA-eastonite, KMg2AlAl2Si2O10(OH)(2) seem not to form in nature. The proposed subdivision has several advantages. All common true, trioctahedral and dioctahedral K micas, whether Li-bearing or Li-free, are shown within one diagram, which is easy to use and gives every mica composition an unambiguously defined name. Mica analyses with Fe2+, Fe3+, Fe2+ + Fe3+, or Fe-tot can be considered, which is particularly Valuable for microprobe analyses. It facilitates easy reconstruction of evolutionary pathways of mica compositions during crystallization, a feature having key importance in petrologically oriented research. Equally important, the subdivision has great potential for understanding many of the crystal-chemistry features of the K micas. In turn this may allow one to recognize and discriminate the extent to which crystal chemistry or bulk composition controls the occurrence of some seemingly possible or hypothetical K mica Y1 - 2004 SN - 0026-461X ER - TY - JOUR A1 - Graubaum, Hans-Joachim A1 - Luder, W.

This technique is applicable to combinational circuits and for scan-BIST in sequential circuits with multiple scan chains. The proposed method relies on the linearity properties of the MISR and on the use of two test sequences, which are both applied to the circuit under test. The second test sequence is derived from the first in a straightforward manner and the same test pattern source is used for both test sequences. If an interval contains only a single failing vector, the algebraic analysis is guaranteed to identify it. We also show analytically that if an interval contains two failing vectors, the probability that this case is interpreted as one failing vector is very low.

The electrode consists of alternating layers of cytochrome c and poly(aniline(sulfonic acid)) on a gold wire electrode. The formation of multilayer structures was proven by SPR experiments. Assemblies with 2-15 protein layers showed electrochemical communication with the gold electrode. For every additional layer, a substantial increase in electrochemically active cytochrome c (cyt. c) was found. For electrodes of more than 10 layers, the increase was more than 1 order of magnitude as compared to monolayer electrode systems. Thermodynamic and kinetic parameters of the electrodes were characterized. The mechanism of electron transfer within the multilayer assembly was studied, with results suggesting a protein-protein electron-transfer model. Electrodes of 2-15 layers were applied to the in vitro quantification of enzymatically generated superoxide, showing superior sensitivity as compared to a monolayer-based sensor. An electrode with 6 cyt. c/PASA layers showed the highest sensitivity of the systems studied, giving an increase in sensitivity of half an order of magnitude versus the that of the monolayer electrode.

T1 - A yeast intron as a translational terminator in a plasmid shuttle vector N2 - Plasmid shuttle vectors that contain both prokaryotic (Escherichia coli) and eukaryotic origins of replication are routinely used in molecular biology since E coli is generally the organism of choice for manipulation of recombinant DNA. Initial transformation of the shuttle vector into E coli allows production of microgram quantities of DNA suitable for transformation of low-transformationefficiency hosts. A shuttle/expression vector for the yeast Kluyveromyces lactis, pCWK1, allows recombinant protein fused to the killer toxin signal sequence to be secreted to the medium. The heterologous genes are transcribed under the control of the K lactis LAC4 promoter, which is tightly regulated in K lactis. However, in E coli the LAC4 promoter functions constitutively, and as a result, uncontrolled transcription and translation of genes that are toxic in E coli can result in cell death, and subsequent failure to recover intact E. coli transformants. We have constructed and tested a modified shuttle vector that contains a K lactis ribosomal intron that acts as a translational terminator in E coli, preventing or reducing the expression of recombinant proteins and avoiding toxicity.

Schleyer. Hereby, quantitative information about the spatial extension, sign and scope of the corresponding ring current/anisotropic effects was obtained and they were visualized as iso-chemical-shielding-surfaces. Examining this quantitative information compared with experimental NMR chemical shifts, the role of the corresponding amino acid residues in binding substrates in the binding site of enzymes was studied.

The calculations showed very good reproducibility of the experimental values. The molecular orbital interactions in the rigid, nearly planar delta-syn-axial fragments in the isomeric groups of norbornane derivatives 1.x-4.x were studied in detail and were employed to explain the deshielding delta-syn-axial effect in C-13 NMR spectroscopy.

Post-war statements by German diplomats portrayed the conservative elite as reluctant participants in Hitler's drive to war. However, an examination of the foreign policy views of German conservatives reveals a significant degree of convergence with Nazi goals in their desire to revise Germany's post-Versailles borders with Poland. In order to understand the role of the German diplomatic elite, it is also necessary to understand the degree to which foreign policy was subject to the same "polycracy" of decision-making instances that characterised the structure of the "Third Reich" in general. While Hitler had relied on the conservative elites, including the Foreign Ministry and the military, their influence on decision-making was waning by 1938-1939 Y1 - 2004 ER - TY - JOUR A1 - Schweigert, Florian J.

The purpose of this study was to evaluate if an accumulation of carotenoids, alpha-tocopherol and retinol in malignant ascitic fluid in women with ovarian cancer might contribute to a loss of these components from plasma. Methods: Blood and ascitic fluid samples obtained from 21 women with ovarian carcinomas and 17 healthy controls were analyzed for retinol, retinol- binding protein (RBP), alpha-tocopherol and carotenoids. Results: Plasma concentrations of all micronutrients were lower in cancer patients compared to controls. Ascitic fluid concentration of all investigated components was comparable (73- 110%) to plasma. While the mean concentration of retinol in malignant ascites represented 73% of that in plasma, the concentration of RBP was less than 10% resulting in an increased mean molar ratio of retinol to RBP from 1.18 to 10.5. Conclusions: The results suggest that lower plasma concentrations of micronutrients in women suffering from ovarian carcinoma are not only caused by a cachexia-induced decrease of food intake and a higher rate of metabolic utilization, but also by a substantial yet not considered transfer from plasma into ascitic fluid possibly associated with plasma lipoproteins. This raises questions with regard to the protective function of these plasma components in ascitic fluid, the consequences of paracentesis on an additional supplementation and finally the possibility to use one or a combination of these components as an additional marker to discriminate between benign and malignant ascites.

T1 - Adding colour to multiplication: Rehabilitation of arithmetic fact retrieval in a case of traumatic brain injury N2 - This study describes ME, a patient in the chronic stage after a traumatic brain injury. During an extensive training programme ME tried to regain automaticity in the retrieval of simple multiplication facts. He succeeded in substantially decreasing response latencies in multiplication, reducing the handicap at his job. This improvement generalised to a non-trained operand order, to non-trained problems, and to a non-trained output modality. Moreover, these effects were maintained over at least four months. Interestingly, however, ME's training effects were operation specific: No significant improvement occurred in addition, subtraction, or division. As coloured presentation of multiplication problems proved to be a valuable cue in facilitating the patient's performance, this might turn out to be a useful tool in the rehabilitation of fact retrieval in general Y1 - 2004 SN - 0960-2011 ER - TY - BOOK ED - Mendes, Alexanda Navas ED - Vazquez, Graciela T1 - Adieu plus : comprension auditiva y visual de clases magistrales ; 14 CD-ROM T3 - Arqueología 02 Y1 - 2004 SN - 3-935024-93-2 VL - 2 PB - Univ.-Verl. CY - Potsdam ER - TY - JOUR A1 - Kuhn, Hans-Peter T1 - Adolescent voting for right-wing extremist parties and readiness to use violence in political action : parent and peer contexts N2 - Almost all shapes of adolescent risky and deviant behaviour take place in the context of peer-relations. The present study examined the role of parents and peer-relations with respect to two indicators of deviant political development. In the fall 1998, directly after the German parliamentary elections, 1309 East German adolescents were asked about their voting for a right-wing extremist party and their readiness to use violence in political action. Friend's voting was a strong predictor of individual voting for a right-wing extremist party, particularly when the friend was the best friend with a reciprocal nomination, and when the friends frequently communicated about political themes. In addition, voting behaviour and willingness to use violence were associated with membership in peer groups who met frequently. Finally, the violence disposed adolescents spent more of their spare time with peers and less with their parents. Similarities of our results with the findings of research on deviant behaviour in non-political areas support the idea that deviant political behaviour could be an expression of a problematic life situation.
