  abstract  = {Myriapods (e. g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda is the only arthropod class not represented by a sequenced genome. We present an analysis of the genome of the centipede Strigamia maritima. It retains a compact genome that has undergone less gene loss and shuffling than previously sequenced arthropods, and many orthologues of genes conserved from the bilaterian ancestor that have been lost in insects. Our analysis locates many genes in conserved macro-synteny contexts, and many small-scale examples of gene clustering. We describe several examples where S. maritima shows different solutions from insects to similar problems. The insect olfactory receptor gene family is absent from S. maritima, and olfaction in air is likely effected by expansion of other receptor gene families. For some genes S. maritima has evolved paralogues to generate coding sequence diversity, where insects use alternate splicing. This is most striking for the Dscam gene, which in Drosophila generates more than 100,000 alternate splice forms, but in S. maritima is encoded by over 100 paralogues. We see an intriguing linkage between the absence of any known photosensory proteins in a blind organism and the additional absence of canonical circadian clock genes. The phylogenetic position of myriapods allows us to identify where in arthropod phylogeny several particular molecular mechanisms and traits emerged. For example, we conclude that juvenile hormone signalling evolved with the emergence of the exoskeleton in the arthropods and that RR-1 containing cuticle proteins evolved in the lineage leading to Mandibulata. We also identify when various gene expansions and losses occurred. The genome of S. maritima offers us a unique glimpse into the ancestral arthropod genome, while also displaying many adaptations to its specific life history.},

  abstract  = {Three DNA regions carrying genes encoding putative homologs of xanthine dehydrogenases were identified in Escherichia coli, named xdhABC, xdhD, and yagTSRQ. Here, we describe the purification and characterization of gene products of the yagTSRQ operon, a molybdenum-containing iron-sulfur flavoprotein from E. coli, which is located in the periplasm. The 135 kDa enzyme comprised a noncovalent (alpha beta gamma) heterotrimer with a large (78.1 kDa) molybdenum cofactor (Moco)-containing YagR subunit, a medium (33.9 kDa) FAD-containing YagS subunit, and a small (21.0 kDa) 2 x [2Fe2S]-containing YagT subunit. YagQ is not a subunit of the mature enzyme, and the protein is expected to be involved in Moco modification and insertion into YagTSR. Analysis of the form of Moco present in YagTSR revealed the presence of the molybdopterin cytosine dinucleotide cofactor. Two different [2Fe2S] clusters, typical for this class of enzyme, were identified by EPR. YagTSR represents the first example of a molybdopterin cytosine dinucleotide-containing protein in E. coli. Kinetic characterization of the enzyme revealed that YagTSR converts a broad spectrum of aldehydes, with a preference for aromatic aldehydes. Ferredoxin instead of NAD(+) or molecular oxygen was used as terminal electron acceptor. Complete growth inhibition of E. coli cells devoid of genes from the yagTSRQ operon was observed by the addition of cinnamaldehyde to a low-pH medium. This finding shows that YagTSR might have a role in the detoxification of aromatic aldehydes for E. coli under certain growth conditions.},

  abstract  = {St{\"a}dte sind aufgrund ihrer Agglomeration von Bev{\"o}lkerung, Sachwerten und Infrastrukturen in besonderem Maße von extremen Wetterereignissen wie Starkregen und Hitze betroffen. Zahlreiche {\"U}berflutungsereignisse infolge von Starkregen traten in den letzten Jahren in verschiedenen Regionen Deutschlands auf und f{\"u}hrten nicht nur zu Sch{\"a}den in zwei- bis dreistelliger Millionenh{\"o}he, sondern auch zu Todesopfern. Und auch Hitzewellen, wie sie in den vergangenen Jahren vermehrt aufgetreten sind, bergen gesundheitliche Risiken, welche sich auch in verschiedenen Sch{\"a}tzungen zu Hitzetodesf{\"a}llen wiederfinden. Um diesen Risiken zu begegnen und Sch{\"a}den infolge von Wetterextremen zu reduzieren, entwickeln viele Kommunen bereits Strategien und Konzepte im Kontext der Klimaanpassung und/oder setzen Anpassungsmaßnahmen um. Neben der Entwicklung und Umsetzung eigener Ideen orientieren sich St{\"a}dte dabei u. a. an Leitf{\"a}den und Beispielen aus der Literatur, Erfahrungen aus anderen St{\"a}dten oder an Ergebnissen aus Forschungsprojekten. Dieser Lern- und Transferprozess, der eine {\"U}bertragung von Maßnahmen oder Instrumenten der Klimaanpassung von einem Ort auf einen anderen beinhaltet, ist bislang noch unzureichend erforscht und verstanden. Der vorliegende Bericht untersucht deshalb ebendiesen Lern- und Transferprozess zwischen sowie innerhalb von St{\"a}dten sowie das Transferpotenzial konkreter Wissenstransfer-Medien, Instrumente und Maßnahmen. Damit wird das Ziel verfolgt, ein besseres Verst{\"a}ndnis dieser Prozesse zu entwickeln und einen Beitrag zur Verbesserung des Transfers von kommunalen Klimaanpassungsaktivit{\"a}ten zu leisten. Der vorliegende Inhalt baut dabei auf einer vorangegangenen Analyse des Forschungsstands zum Transfer von Policies durch Haupt et al. (2021) auf und versucht, den bereits generierten Wissensstand auf der Ebene von Policies nun um die Ebene konkreter Instrumente und Maßnahmen zu erg{\"a}nzen sowie durch empirische Befunde zu ausgew{\"a}hlten Maßnahmen zu untermauern. Die Wissens- und Datengrundlage dieses Berichts umfasst einen Mix aus verschiedenen (Online)-Befragungen und Interviews mit Vertreter:innen relevanter Akteursgruppen, vor allem Vertreter:innen von Stadtverwaltungen, sowie den Erfahrungswerten der drei ExTrass-Fallstudienst{\"a}dte Potsdam, Remscheid und W{\"u}rzburg. Nach einer Einleitung besch{\"a}ftigt sich Kapitel 2 mit {\"u}bergeordneten Faktoren der {\"U}bertragbarkeit bzw. des Transfers. Kapitel 2.1 bietet hierbei eine Zusammenfassung zum aktuellen Wissensstand hinsichtlich des Transfers von Policies im Bereich der st{\"a}dtischen Klimapolitik gem{\"a}ß Haupt et al. (2021). Hier werden zentrale Kriterien f{\"u}r einen erfolgreichen Transfer herausgearbeitet, um einen Ankn{\"u}pfungspunkt f{\"u}r die folgenden Inhalte und empirischen Befunde auf der Ebene konkreter Instrumente und Maßnahmen zu bieten. Kapitel 2.2 schließt hieran an und pr{\"a}sentiert Erkenntnisse aus einer weitreichenden Kommunalbefragung. Hierbei wurde untersucht ob und welche Klimaanpassungsmaßnahmen in den St{\"a}dten bereits umgesetzt werden, welche f{\"o}rdernden und hemmenden Aspekte es dabei gibt und welche Erfahrungen beim Transfer von Wissen und Ideen bereits vorliegen. Kapitel 3 untersucht die Rolle verschiedener Medien des Wissenstransfers und widmet sich dabei beispielhaft Leitf{\"a}den zur Klimaanpassung und Maßnahmensteckbriefen. Kapitel 3.1 beantwortet dabei Fragen nach der Relevanz und Zug{\"a}nglichkeit von Leitf{\"a}den, deren St{\"a}rken und Schw{\"a}chen, sowie konkreten Anforderungen vonseiten befragter Personen. Außerdem werden acht ausgew{\"a}hlte Leitf{\"a}den vorgestellt und komprimiert auf ihre Transferpotenziale hin eingesch{\"a}tzt. Kapitel 3.2 betrachtet Maßnahmensteckbriefe als Medien des Wissenstransfers und arbeitet zentrale Aspekte f{\"u}r einen praxisrelevanten inhaltlichen Aufbau heraus, um basierend darauf einen Muster-Maßnahmensteckbrief f{\"u}r Klimaanpassungsmaßnahmen zu entwickeln und vorzuschlagen. Kapitel 4 besch{\"a}ftigt sich mit sehr konkreten kommunalen Erfahrungen rund um den Transfer von sieben ausgew{\"a}hlten Instrumenten und Maßnahmen und bietet zahlreiche empirische Befunde aus den Kommunen, basierend auf der Kommunalbefragung, verschiedenen Interviews und den Erfahrungen aus der Projektarbeit. Die folgenden sieben Instrumente und Maßnahmen wurden ausgew{\"a}hlt, um eine große Breite st{\"a}dtischer Klimaanpassungsaktivit{\"a}ten zu betrachten: 1) Klimafunktionskarten (Stadtklimakarten), 2) Starkregengefahrenkarten, 3) Checklisten zur Klimaanpassung in der Bauleitplanung, 4) Verbot von Schotterg{\"a}rten in Bebauungspl{\"a}nen, 5) Fassadenbegr{\"u}nungen, 6) klimaangepasste Gestaltung von Gr{\"u}n- und Freifl{\"a}chen sowie 7) Handlungsempfehlungen f{\"u}r Betreuungseinrichtungen zum Umgang mit Hitze und Starkregen. F{\"u}r jede dieser Klimaanpassungsaktivit{\"a}ten wird auf Ebene der Kommunen Ziel, Verbreitung und Erscheinungsformen, Umsetzung anhand konkreter Beispiele, f{\"o}rdernde und hemmende Faktoren sowievorliegende Erfahrungen zu und Hinweisen auf Transfer dargestellt. Kapitel 5 schließt den vorliegenden Bericht ab, indem zentrale Transfer-Barrieren aus den gewonnenen Erkenntnissen aufgegriffen und entsprechende Empfehlungen an verschiedene Ebenen der Politik ausgesprochen werden. Diese Empfehlungen zur Verbesserung des Transfers von klimaanpassungsrelevanten Instrumenten, Strategien und Maßnahmen umfassen 1) die Verbesserung des Austauschs zwischen verschiedenen St{\"a}dten, 2) die Verbesserung der Zug{\"a}nglichkeit von Wissen und Erfahrungen, 3) die Schaffung von Vernetzungsstrukturen innerhalb von St{\"a}dten sowie 4) bestehende Wissensl{\"u}cken zu schließen. Die Autor:innen des vorliegenden Berichts hoffen, durch die vielf{\"a}ltigen Untersuchungsaspekte einen Beitrag zum besseren Verst{\"a}ndnis der Lern- und Transferprozesse und zur Verbesserung des Transfers kommunaler Klimaanpassungsaktivit{\"a}ten zu leisten.},

  abstract  = {Porous, layered materials containing sp(2)-hybridized carbon and nitrogen atoms, offer through their tunable properties, a versatile route towards tailormade catalysts for electrochemistry and photochemistry. A key molecule interacting with these quasi two-dimensional materials (2DM) is water, and a photo(electro)chemical key reaction catalyzed by them, is water splitting into H-2 and O-2, with the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) as half reactions. The complexity of some C/N-based 2DM in contact with water raises special needs for their theoretical modelling, which in turn is needed for rational design of C/N-based catalysts. In this work, three classes of C/N-containing porous 2DM with varying pore sizes and C/N ratios, namely graphitic carbon nitride (g-C3N4), C2N, and poly(heptazine imides) (PHI), are studied with various computational methods. We elucidate the performance of different models and model chemistries (the combination of electronic structure method and basis set) for water and water fragment adsorption in the low-coverage regime. Further, properties related to the photo(electro)chemical activity like electrochemical overpotentials, band gaps, and optical excitation energies are in our focus. Specifically, periodic models will be tested vs. cluster models, and density functional theory (DFT) vs. wavefunction theory (WFT). This work serves as a basis for a systematic study of trends for the photo(electro)chemical activity of C/N-containing layered materials as a function of water content, pore size and density.},

  abstract  = {Ferroelectric polyamide 11 films were prepared by melt-quenching, cold-drawing and electrical poling. Their ferroelectricity was studied by means of dielectric-hysteresis measurements. A remnant polarisation of up to 35 mC/m(2) and a coercive field of 75 MV/m were obtained. The piezoelectric d(33) coefficient and the pyroelectric coefficient of the films are reduced by annealing just below the melting region, but remain at about 3 pC/N and 8 muC/(m(2)K), respectively, during further heat treatment. Differential scanning calorimetry (DSC), dielectric relaxation spectroscopy (DRS) and thermally stimulated depolarisation (TSD) were applied for investigating the conformational changes induced by melt-quenching, cold-drawing and annealing. The results indicate that the cold-drawn film mainly consists of a rigid amorphous phase which exhibits considerably lower conductivity, no glass transition and consequently no dielectric a relaxation. Instead, an a, relaxation is found, which is related to chain motions in regions of the rigid amorphous phase where the amide-group dipoles are not perfectly ordered. Annealing removes imperfectly ordered structures, but does not affect the ferroelectric polarisation. Therefore, it may be concluded that essentially the a, relaxation causes the thermally non-stable part of the piezo- and pyroelectricity in polyamide 11},

  abstract  = {By means of pyroelectrical measurements and dielectric spectroscopy as well as structural information from differential scanning calorimetry, it is shown that, in a poly(vinyl alcohol) with azobenzene-alkoxy side chains, pyroelctricity and dielectric hysteresis which are usually related to each other have different origins. The pyroelectric effect is explained with reversible dipole-density changes upon thermal expansion, whereas the dielectric hysteresis is proposed to result from a charge-carrier polarisation.},

  abstract  = {'Biodiversity' is increasingly perceived as an important resource for research and conservation, but also for economy. Conservation, access and sustainable use of biodiversity (genetic resources, species, samples) are negotiated on different political levels, resulting in an internationally binding legal framework. Resulting legislation is binding for all parties involved in biological sampling, i.e. researches and (and in italics) countries, and especially applies for tissue or DNA samples and dervied products thereof. Understanding and awareness of export and import permits for biological samples is increasingly important for biologists to perform research projects legally and timely. Nevertheless, some biologists are still exporting and importing biological samples ignoring or noncompliant with national and international legislation, conventions, and regulations. Resulting difficulties may not only cause serious problems during field work, but may also delay the export, import or exchange of samples. Comprehensive a priori information regarding legal requirements helps to avoid or at least diminish potential problems. We identified four major factors facilitating export/import permits: (1) good personal (mutually trusted) contacts in the country of origin, (2) understanding and compliance with all relevant laws and regulations; (3) access to information regarding knowledge on permits, regulations and laws including their circulation within the researcher communities; and (4) access to consistent and up to date regulations},
