Ehrensache, dass Wuttigs das Kind solange betreuen. The responsible surgeons of all congenital cardiac surgery departments commit to participate in the currently voluntary national quality assurance for congenital cardiac defects of the GSTCVS and the GSPC and perform an individual surgical outcome assessment and risk stratification. This is supplemented by the willingness for external certification specific to the individual and the facilitation of peer review procedures for quality assurance purposes.
Additional measures, such as collaboration in clinical research and ongoing interdisciplinary education and training, are preferable. A multiple regression analysis showed the interrelationships between the parameters measured. Tidal influences on zooplankton and seston dry weight could be observed.
At low tide, the amount of zooplankton not counting the harpacticoid copepods declines and the number of harpacticoid copepods rises as does the seston dry weight too. The chlorophyll-a content is a function of the phytoplankton-nutrients. An increase in chlorophyll-a leads to a decrease in nitrogen and silicate concentrations. The availability of nutrients is influenced by temperature, salinity and the tidal cycle.
The amount of oxygen is dependent on water temperature and seston dry weight. High water temperatures and a high seston content lead to a decrease in oxygen concentrations. The reasons for creating international auxiliary languages, such as Esperanto, are examined. The study of the synthesis of such languages is considered useful for linguistic theory. Available from Humanities Press, Inc. In the context of an application for a shale gas exploration license including hydraulic fracturing, the Geological Survey of Hessen HLNUG has grouped and ranked structural geological regions in terms of their shale gas potential and the function of overlying rocks as barriers.
Tectonic and structural features as well as the type of reservoir have been examined. Rock units overlying the shale gas layers have been classified as hydrogeological units and divided into aquifers and hydraulic barriers. Possible effects on drinking water abstraction facilities, mineral springs and water for industrial use have also been estimated, followed by an analysis of competing requirements for land use. Tokamak und Stellarator - zwei Wege zur Fusionsenergie: Parallel soll die in Greifswald entstehende Forschungsanlage Wendelstein 7-X die Kraftwerkstauglichkeit des alternativen Bauprinzips der Stellaratoren zeigen.
Knowing the hydraulic conductivity K is a precondition for understanding groundwater flow processes in the subsurface. Numerous laboratory and field methods for the determination of hydraulic conductivity exist, which can lead to significantly different results. In order to quantify the variability of these various methods, the hydraulic conductivity was examined for an industrial silica sand Dorsilit using four different methods: Due to the large volume of the artificially built aquifer, the tank experiment results are assumed to be the most representative.
Hydraulic conductivity values derived from permeameter tests show only minor deviation, while results of the empirically evaluated grain-size analysis are about one magnitude higher and show great variances. The latter was confirmed by the analysis of several methods for the determination of K-values found in the literature, thus we generally question the suitability of grain-size analyses and strongly recommend the use of permeameter tests.
Caudal regeneration was investigated in decerebrate Anaitides mucosa and in brain-intact individuals. Both groups show an identical capacity to regenerate lost caudal segments. Furthermore there is no difference in males and females. At the same time degeneration of most oocytes occurs. Mikrobielle Kurzzeitteste zur Bestimmung der mutagenen Potenz chemischer Substanzen. During the last 20 years it became much more interesting to test new chemicals as fast as possible for their carcinogenic potency. Therefore new test models were developed.
Mutagenicity seems to be one sign for carcinogenicity. Therefore test systems using microorganisms were studied which are influenced by mutagenic substances. The yeast Saccharomyces cerevisiae was introduced some years ago and finally the Neurospora crassa system serves as an additional test to define exactly the localisation of mutations. The tests and their problems are discussed. Restrospektive Studie zur Analyse von klinischen Merkmalen, videodermatoskopischen Bildern, histopathologischen Diagnosen und Behandlungsergebnissen. Der Grad der Pigmentierung wurde sowohl klinisch als auch histopathologisch beurteilt.
Das Muster der Pigmentierung korrelierte signifikant mit dem Alter der Patienten: Die Komplikationen begannen mit einer unspezifischen Schwellung. Die Zusammensetzung des inkorporierten Farbstoffs wurde mittels Rasterelektronenmikroskopie in Kombination mit energiedispersiver Elementanalyse analysiert. Zur weiteren Charakterisierung wurden Thermogravimetrie und Pulverdiffraktometrie eingesetzt. Groundwater pollution with organic contaminants remains a world-wide problem.
Before selection of any remediation technique, it is important to pre-assess contaminated sites with respect to their hazard. These approaches differ from each other in source geometry, model domain orientation, and in the consideration of bio chemical reaction within the domain.
In this communication, we provide details about the development of "NAFLA", its possible usage and information for users. The tool is especially designed for application in student education, by authorities and consultants. Von den Flitterwochen zur distanzierten Partnerschaft. A recent wave of takeovers by private equity investors and foreign investors from emerging economies has challenged German executives. In cases of friendly takeovers, as described in this study, managers at first appear to extend a cosmopolitan welcome to the new owners.
However, further analysis of structural hermeneutics reveals latent normative professional ethics of managers which lead to practices of distancing, in particular from young investors from China, India, and Russia. Traces the history of sociolinguistic studies in West Germany from the early nineteenth century with Humboldt and reports on the state and purposes of sociolinguistic studies in present-day Federal Republic of Germany. Dass diese Entwicklung noch lange nicht abgeschlossen ist, zeigt die derzeitige Diskussion zum Thema Web 2. The estimation of groundwater recharge in water-limited environments is challenging due to climatic conditions, the occurrence of deep unsaturated zones, and specialized vegetation.
We critically examined two methods based on stable isotopes of soil water: Numerous depth-profiles were measured directly in the field in semiarid Namibia using a novel in-situ technique. Additionally, 2H2O was injected into the soil and its displacement over a complete rainy season monitored.
The results of this study fortify the suitability of water stable isotope-based approaches for recharge estimation and highlight enormous potential for future studies of water vapor transport and ecohydrological processes. This paper reports experience with direct quantitative trace element determinations in powdered geological samples by nameless atomic absorption spectroscopy. Two methods were explored. The first one is based on the production of a sample aerosol by laser radiation in a specifically designed sample chamber and the subsequent transport of the aerosol into a graphite tube, which has been preheated to a stable temperature.
This technique is suited for a large range of concentration and is relatively free from matrix interferences. The described sample chamber can be also used in combination with other spcctroscopic techniques. The second method explored permits the quantitative determination of trace elements at very low concentrations. Essentially an accurately weighed amount of sample is placed on a graphite rod and introduced into a graphite furnace by inserting the rod through the sample injection port.
Atomization takes place also under stable temperature conditions. Acidic microenvironmental conditions combined with large hypoxic areas are ubiquitous hallmarks of most solid tumors. They result from a poorly organized vascularization and a deviant energy metabolism. There is convincing evidence supporting the hypothesis that such physico-chemical conditions promote the microevolution of malignant cells, inhibit the cellular immune response, and favor tumor cell invasion. In agreement with published data, our cell biological analyses and computer simulations indicate that treatment schemes which restore a tumor microenvironment reflecting that one found in normal tissues might improve the efficiency of immunotherapies and classical methods for cancer treatment.
We suggest that the tumor microenvironment could be effectively monitored and manipulated by means of silicon-based feedback bioactuators which are controlled by integrated microsensors. In principle, miniaturized bioactuators can be implanted directly at the sites of inoperable tumors and metastases where they function as a "pH clamp" and thereby can reconstitute normal physico-chemical conditions. Drug application could be precisely controlled by an integrated microprocessor.
Our paper summarizes the current state of development of microsensor-based feedback bioactuators and outlines possible applications in biophysical cancer treatment. This book collects about 15 papers most of them by one single author on Einstein and the history of general relativity GR and the foundations of relativistic cosmology. The matter not only deals with Einstein and his times, but also with pre-GR ideas, and with the interplay of Einstein and his colleagues opposing as well as supporting personalities.
As the title indicates, all papers are written in German, but they include comprehensive Abstracts both in German and English. The book is illustrated with quite a number classical - but also some far more original though not less beautiful - photographs and facsimiles of documents. The book is edited very well, though the style of references is not quite homogeneous.
There is no Index. Hentschel covers Einstein's argumentation for the existence of graviational redshift, and the initial search for empirical support. The error analysis of observational evidence supporting relativistic light deflection is discussed in a paper by P. Flin - in their description of the life and work of Silberstein, who was quite sceptic on the significance of the observational verifications a la Eddington - include the transcription of two most revealing letters by Silberstein to Sommerfeld and to Einstein In the first letter, Silberstein clearly shows his scientific maturity and integrity by scrutinising the observational evidence supporting light deflection, presented at a joint meeting of the Royal Society and the Royal Astronomical Society.
The second letter, which is more a personal letter, includes lots of political references and connotations. Some of Einstein's political views are also revealed by D. Herrmann on the basis of his own correspondence with E. Straus, a collaborator of Einstein's. In a consequent paper, S. Grundmann gives remarks on Herrmann's contribution and illustrates Einstein's attitude towards Marx, Engels, Lenin and Stalin. Schemmel discusses Schwarzschild's cosmological speculations, and wonders why some people do immediately grasp the meaning and consequence of newly proposed doctrines, whereas the bulk of the contemporaneous scientists respond in a rather low profile.
Jung reviews Einstein's contribution to cosmology, leading to the Friedmann-Einstein and Einstein-de Sitter universes with a detailed Appendix on the Friedmann-Lemaitre cosmology , and also presents the cosmological work of Selety, and his correspondence with Einstein. In a subsequent paper, H. Schmidt comments on Einstein's criticism on de Sitter's solution of the Einstein field equations. Controversies with Einstein are elaborated by G. Singer on Friedmann and by K. Sauer discuss Mandl's role in the publication history of Einstein's papers, notably Einstein's short paper on gravitational lensing.
Finally, the book concludes with a contribution by D. Herrmann about the relationship between Einstein and Archenhold Observatory where Einstein gave his first Berlin popular lecture in , the transcription of H. Treder's public address at the Einstein memorial plaque, and an inventory list of about 50 Einstein memorabilia - monuments, busts, plaques - compiled by W. This book is based on ideas approached in a historical context from the individual perspective of the authors.

It is a real treasure trove of information and basic references on the history of GR, and it also covers quite some grounds with mathematical equations. For many tracer experiments, prior determination of interaction between solid medium and used tracers is of major interest in order to achieve efficient, economic and successful field experiments. In the present study, three different types of batch experiments were performed with three fluorescent dyes Na-Fluorescein, Amidorhodamin G and Tinopal CBS-X and three different rock types sandstone, claystone and limestone , to determine distribution coefficients and reaction kinetics.
All three rock types were analysed for organic carbon content, specific surface area and mineralogical composition to identify the main sorption mechanisms.
zur oekotoxikologischen charakterisierung: Topics by oxivecakyhub.ga
For all tracers, different sorption properties were found depending on the type of rock. Only Na-Fluorescein showed sorption albeit limited in contact with the sandstones. Regarding reaction kinetics, in most cases, thermodynamic equilibrium conditions were reached after two weeks.
Reforms and Innovations in Estonian Education. Baltische Studien zur Erziehungs- und Sozialwissenschaft. This collection of papers provides a small overview of educational research in Estonia. The papers in the collection treat school reforms since the renewal of independence in , new approaches to teacher training, the implementation of a child-centred approach in school, the achieving of educational aims and other actual topics in education.
One Focus, Different Systems. Studien zur Erwachsenenbildung, Band These 17 articles on different subjects of the broader theme "lifelong learning" represent the latest results of the discussions of the Vocational Education and Culture Research Network. An introduction Klaus Harney et al. This collection includes eight papers authored by Germans on adult education programs in Cleveland, Ohio, and eight papers authored by Americans about adult education programs in the Federal Republic of Germany as well as German and English introductions to the collection.
The following papers are included: Describes the purpose, structure and application of this monolingual verb lexicon, which indicates the morphosyntactic environments of the most common German verbs. Mention is made of the forthcoming valence lexicon. The book is for teachers and textbook writers. Learning to read foreign technical texts requires a a minimum vocabulary and b effective drill.
The following are suggested: In areas where the geological subsurface is used for storage of gases or fracking, there is a risk of saline formation water entering protected aquifers.
The impact of such potential leakage therefore needs to be evaluated at relevant sites to develop practical monitoring concepts. Three-dimensional numerical simulations and a sensitivity analysis are performed to determine the influence of aquifer parameters, ground water flow, aquifer morphology, leakage rate and NaCl-concentration of the intruding water on the propagation behaviour of saline water.
The simulations show that saltwater migrates along the bottom of the aquifer, and that groundwater flow can dominate the transport of chloride. In this case the spreading of denser water is not influenced by the aquifer's morphology. This innovative technology evaluation report ITER summarized the results of an evaluation of a surfactant-enhanced extraction technology.
This evaluation was conducted under a bilateral agreement between the United States U. New insights into the biography of Gottfried Kirch. Neue Erkenntnisse zur Biographie von Gottfried Kirch. New biographical results of Gottfried Kirch, the most outstanding astronomer around in German lands, are outlined on the basis of newly found sources and the first-time inclusion of additional letters from his correspondence, which comprises letters.
In addition, new details about his family are revealed, especially about the older children Gottlieb, Heilmann and Theodora, the offspring from his first marriage. A third section deals with the possibilities which are to be expected from a systematic evaluation of Kirch's correspondence. Only about out of letters have been used for historical publications until now.
Comparative investigations on the physiological capacities in the euryhaline amphipods Gammarus locusta, G. In order to assess the adaptations of these species to the abiotic conditions of their environment, the following criteria were examined: Covering the range from marine to typically brackish-water inhabitants, the 5 species show adaptive responses in the above-mentioned order. Respiration is less intensely modified by external factors, and oxygen consumption decreases. Accompanied by faster rates of acclimation to new steady states of performance, resistance capacities increase.
The significance of the findings obtained is discussed in relation to the environmental requirements of the amphipods considered. Based on breeding experiments, the sex-determining systems reported thus far in Gammarus species are outlined. As demonstrated in G. A preponderance of males was noted when offspring were raised under long-day photoperiods, whereas females prevailed under short-day conditions. In terms of the critical daylength, the light per day was estimated as being between 13 and 14 h Elbe estuary population. Feminizing microporidians Octosporea effeminans, Thelohania herediteria , which are transovarially transmitted, can interfere with the system of sex determination and sex differentiation of the host.
As reflected in various G. Furthermore, intersexuality can be induced by changing environmental factors. Microsporidian species have no influence on sex differentiation in G. Patterns of relative electrophoretic mobilities of proteins and the distribution of allele frequencies at polymorphic gene loci can be utilized for species diagnosis and for the evaluation of the relationships between different taxa, particularly at and below the species level.
As exemplified by studies on several gammarids from marine, brackish and freshwater environments, inter- and infraspecific gene-enzyme variation is described. Electrophoretic investigations on natural populations of the euryhaline amphipods G. In Talitrus saltator- and Talorchestia deshayesii-populations the extent of variability based on micro-and macrogeographic aspects is illustrated.
The large-scale genetic divergence is demonstrated by comparison of samples obtained from the Baltic, North, Atlantic and northern Mediterranean Seas. Viele Wurzeln der modernen Umweltwissenschaften liegen jedoch im Kalten Krieg. Zur Klaerung zweier zentraler Begriffe Drilling-Testing. On the Clarifications of Two Central Concepts. It is shown that drilling tends to become contaminated with elements of testing. The two activities are defined, and suggestions are given for designing drills free of testing.

Newly found copies of Copernicus' principal work are described, the development of the concepts "sphaera" and "orbis coelestis" from ancient times via Copernicus to Kepler is investigated. The concept of harmonical cosmology of Kepler and A. Kircher is analyzed in a major paper. A rediscovered letter by Kepler is interpreted. Einstein's thoughts about Friedmann's cosmological papers are presented.
Biographical sketches on Philipp Feselius , Ferdinand Adolph Freiherr von Ende , Wilhelm Ebert and Karl Julius Lohnert are supplemented by an analysis of the social background of the important Astronomers of the 20th century. The claim that Jupiter's moons were described already years before Galilei is contradicted in a discussion.
The book concludes by short communications, obituaries and book reviews. Groundwater is the largest and oldest continental biome. However, in the German and EU legislation, groundwater is still considered an abiotic resource rather than an ecosystem.
On the other hand, the German Water Act WHG, Wasserhaushaltsgesetz mentions groundwaters along with other water bodies that carry the status of ecosystems. Addition of the terms "good ecological status" and "groundwater ecosystems" into the German and EU environmental water laws is recommended.
Groundwater habitats and species should be subject to impact assessment and included into the FFH directive and German nature conservation laws. There is no technical or legal argument for the discrimination of groundwater ecosystems and species in environmental legislation. The authors argue for the legal equality of ground and surface water, and propose the adaption of the existing legislation according to ecological requirements.
Bessel , with the Mecklenburg ordnance survey , with previously unknown letters by C. Gauss , with the merits of the Leipzig astronomer G. Jahn, with the internationality of the Astronomische Gesellschaft, and with early, previously little noted works on the expansion of the Universe. Most papers in German, one in English. Short contributions and book reviews conclude this volume. Most papers are written in German. Main papers have English abstracts. The contributions span a time interval of more than years. There are biographical investigations on Georg Joachim Rheticus, C.
Heym, investigation on a reprint of a chapter of the principal work of Nicolaus Copernicus, on Christoph Scheiner and the "camera obscura", and, with respect to the history of timekeeping, on the "big Nuremberg clock". On the other hand, Geo-Information-Systems GIS provide useful tools for data preparation and visualization that can also be incorporated in numerical groundwater modelling. An interface between both would therefore be useful for many hydrogeological investigations.
Simultaneously, several open source-GIS codes were developed to improve functionality and ease of use.
However, both the public and the potentially affected labour force often adopt sceptical, and sometimes even hostile attitudes towards investors from these countries. This article shows that apart from a few exceptions investors from the BRIC countries are generally better than their reputation precedes. An important conclusion drawn in this paper is that investors should not be received with stereotypes. Rather, it is necessary to perform deeper investigations into their strategies and the specific investment goals in each case.
This is all the more necessary to ensure that investments from BRIC countries do not conflict with the domestic firms' interests or of their personnel. In fact, they can assist to increase the competitiveness of German firms, and as such not only prove beneficial for the workforce but also for Germany as a business destination. Experimental design, limitations and application boundaries are discussed and methods are compared against each other. The quality of the predictive methods strongly depends on the experimental design and the sample type.
In contrast to the retail sector in metropolises and medium-sized towns, its counterpart in rural regions is far less examined and described in scientific geographic literature. As many rural communities face similar challenges e. Next to "hard" facts, as for example accessibility and parking spaces, less tangible themes like quality of stay, multicontextuality or service as well as comprehensive concepts like city marketing or place branding take on greater significance.

Passages from three selected samples of textbooks are used to show what requirements are made of textbooks in the social sciences. Some hints are given to the teacher for converting reading suggestions into instructional material. Short texts from Karl Marx are also suggested. Due to climate change, but also because of the demographic change and financial constraints in many municipalities, the future of cities is a currently much-discussed topic.
Conflicts over land-use are inevitable: As densification is an essential principle in growing cities, the pressure on open green spaces rises. Climate Change and water-management as well as mobility-issues and air-quality confront municipalities with new challenges, in terms of open space planning and greenery in the city.
It is necessary to save the existing green in these days of budget-shortage and other priorities in communities. Municipalities have to raise new strategies to strengthen the awareness of the value of green in public and in the local business. Urbanisation processes increase land-use conflicts and ecosystem destruction globally.
Especially in China, a country with an outstanding urbanization rate, city governments are challenged by environmental and health problems. Urban green spaces - subsequently defined as urban biodiversity and ecosystem services - can minimize numerous environmental risks and at the same time contribute to the citizens' well-being and quality of life. In this highly relevant field of nature conservation, geographical perspectives are required - in science, politics, policy, planning and practice.

Draws on Wilhelm von Humboldt's typology of the active human being to debate the questions whether and how individuals can produce their social and political world. Discusses, with reference to Marie Condorcet and Immanuel Kant, procedures of the public that are necessary prerequisites for actions aimed at forming the world. Discusses the relationship between planned languages and specialized technical languages, with particular reference to Esperanto, and analyzes its significance for several aspects of Eugen Wuster's the founder of terminology science work.
On the Discussion of the Japanese Educational System. Suggests a reconsideration of the criticism of Japanese competition against the background of the Japanese educational system's highly developed learning culture. Considers some of the basic aspects of group-oriented communal learning in school, while also cautioning against a "monocausal" culturalism. On the Use of "Personal Journalism" in Teaching. Discusses American journalism--specifically the syndicated columns. To show their usefulness for English teaching, Art Buchwald's "Unqualifications" is described and the text interpreted.
It is suggested that for humorous aspects and language deviations be stressed; for Grades irony, American technology and education. Porosity is a fundamental parameter in hydrogeology. The empirical method of Beyer and Schweiger allows the calculation of hydraulic conductivity and both the total and effective porosity from granulometric data. However, due to its graphical nature with type curves, it is tedious to apply and prone to reading errors. In this work, the type curves were digitized and emulated by mathematical functions. The latter were implemented into a spreadsheet and a visual basic program, allowing the fast automated application of the method for any number of samples.
Zur Afuwertung der Kultur- und Landeskunde. A Survey of the Literature. Eight recent monographs and collections on area and culture study in foreign language teaching are discussed and compared. The focus is on the various authors' definitions of the topic culture, civilization, realia, etc.
Mentioned also is the function of area study in the course. Hydraulische Optimierung des Reaktionsraumes um einen Infiltrationsbrunnen zur unterirdischen Enteisenung. In subsurface iron removal SIR , oxygen-enriched water is injected into an aquifer to create a reaction zone. Aside from the hydraulic properties of the aquifer, groundwater quality often varies with depth so that in vertical wells the dissolved oxygen distribution reaction zone may not correspond to the dissolved iron concentration which may result in a lower efficiency coefficient.
Therefore, measures to hydraulically optimize the formation of the reaction zone through a non-conventional injection were investigated. A high-resolution groundwater flow model was calibrated based on tracer and pump tests and used to plan the optimized injection for a SIR-pilot well with two screen segments. An optimized injection appears to be possible through the inactivation of well screen sections using packers. This scenario was used to plan the operating regime for a SIR field test, which is presented in Part 2.
Focuses on motives leading women in the new German Laender to participate in further education and on gender-related barriers to further education. Shows that women accept the need for further education, hoping to improve their job situation but knowing that their efforts will have a limited effect on employment chances. Heinrich Bruns, director of the Leipzig University Observatory, was working on theoretical geometrical optics, and applied this to practical questions. His correspondence with opticians of the Zeiss Company in Jena gives evidence of their mutual regard and inspiration.
Konzeption, Entwicklung und Evaluierung eines Messsystems zur sortenreinen Klassifikation von fluoreszenzcodierten Kunststoffen im Rahmen des Kunststoff-Recyclings Conception, development and evaluation of a measuring system for the classification of fluorescence coded plastics within the framework of plastic recycling. The use of modern terminology hinders to understand historical astronomical texts and often misleads the reader. Therefore, this study tries to reconstruct the ideas of the way the planets seem to move against the sphere of fixed stars in a non-teleological manner, that means in the original view and with original terms.
The study proceeds historically and explains: The space which they take up in all is surrounded by an inner and an outer concentric spherical surface and makes the sphere of the planet. It was particularly Kepler who recognizes that as a result celestial physics requires a complete change. He did not think any more that the apparent unequal way of a planet indirectly results from the combination of several equal movements of etherial partial and entire spheres. His planets move their true and real way caused directly by the joint effect of two corporal forces moving the planets both around the sun and to and from it, which latter makes the planet's speed indeed naturally unequal.
For this "real way" he coins in late the specific term "orbita" the modern "orbit", the German "Bahn". This term then little by little replaced the former non-specific, general description of the apparent or real way as "via, iter, ambitus, circulus, circuitus" etc. This way Kepler marks the paradigm change of astronomy caused by himself also terminologically. Reports on the introduction of video recorders at various branches of the Goethe Institute. The characteristics of video are compared with those of films, tapes and printed matter. Video's advantage is that through it authentic, unprepared material can be presented, and it provides strong motivation.
On the Situation in the Near East: Fleet Activities in the Indian Ocean: Flottenaktivataeten in Indischen Ozean: Ueberblick vom Juli bis August With the end of the Iranian-American hostage crisis in late Beira and Port Louis. Literaturunterricht als Erziehung zum "rationalen Handeln. Using Richard Wright's novel "Black Boy" as a model to work on, the author illustrates a 4-dimensional approach to the teaching of foreign literature: This year more than 60 doctoral students and postdocs from over 25 different groups working in German university hospitals or research institutes attended the meeting to discuss their latest findings in the fields of neuroimmunology, neurodegeneration and neurovascular research.
All participants appreciated the stimulating environment in Motzen, Brandenburg, and people took the opportunity for scientific exchange, discussion about ongoing projects and already started further collaborations. Like in the previous years, the symposium was regarded as a very well organized platform to support research of young investigators in Germany. This outstanding paper deals with the function of Schwann cell neuregulin as an endogenous factor for myelin repair.
The award is endowed with Characterization of the response to zinc deficiency in the cyanobacterium Anabaena sp. Zur regulators control zinc homeostasis by repressing target genes under zinc-sufficient conditions in a wide variety of bacteria. This paper describes how part of a survey of duplicated genes led to the identification of the open reading frame all as the gene encoding the Zur regulator of the cyanobacterium Anabaena sp. All binds to DNA in a zinc-dependent manner, and its DNA-binding sequence was characterized, which allowed us to determine the relative contribution of particular nucleotides to Zur binding.
A zur mutant was found to be impaired in the regulation of zinc homeostasis, showing sensitivity to elevated concentrations of zinc but not other metals. In the Name of Love! Swing Girl Switch Girl!!
