On The Future Of History Breisach Ernst File

I am really pleased with this. Hopefully more people will be aware of the works of Marius. So auch Simon Marius. In Padua studierte er Medizin, doch seiner Liebe und Leidenschaft zur Astronomie blieb er immer treu. Seine Ergebnisse publizierte er aber erst im Mundus Iovialis. Zu Unrecht wie wir heute wissen. Er stammte aus der damaligen Markgrafschaft Ansbach und setzte etwa gleichzeitig mit Galileo Galilei als einer der ersten ein Fernrohr zur Himmelsbeobachtung ein.

Die Brennstoffzelle hat aus technischer Sicht einen hohen Stand erreicht. Am September wurde ein weiterer wichtiger Meilenstein erfolgreich, rechtzeitig und innerhalb des Kostenplans erreicht. Von Anfang an konnte es eine Reihe exzellenter astronomischer Bilder aufnehmen. Dieses einzigartige Instrument ist nun im Cassegrain-Fokus installiert und verschwindet beinahe, trotz seiner Dimensionen von 3 x 1. Der wichtigste Risikofaktor war die Gesamtzahl der verabreichten Medikamente. Die Arzneimittelgruppen, die bei der Mehrzahl der Wechselwirkungen beteiligt waren, waren Analgetika, Herz-Kreislauf-Medikamente und gerinnungshemmende Medikamente sowie Antidepressiva.

Astronomical ephemerides, navigation and war. Edition of the documents. Edition der Dokumente. During the whole period of the Second World War, England and the USA have exchanged astronomical ephemerides with Germany, even though these data were used for the navigation of warships and aircraft and were therefore of war importance.

This astonishing fact is attested by numerous documents which survived in the archives of the Astronomisches Rechen-Institut ARI. In Germany, the exchange was even explicitly authorized by the ministry which supervised the ARI i. We present here examples of ephemerides for the Sun, the Moon, planets and stars, and explain the position determination by means of astronomical data.

Ephemerides were published in almanacs which were computed and issued by special ephemeris institutes. We describe the agreements on the international exchange of ephemerides which were reached in peace times, and the continuation of this exchange during the war using intermediaries in neutral countries, first in the USA U. Involved persons were especially H. Hellweg und W. Lindblad Sweden , and A. Kopff ARI. All those relevant documents which are hold in the archives of the ARI, are described and annotated in detail.

Scans of these documents are presented in a separate supplement. Die Evaluierung der Umsetzung belegt den deutlichen Mehrwert des Ansatzes. Kaum eine Branche hat in den letzten zehn Jahren einen tiefgreifenderen Wandel erfahren als die Energiewirtschaft. Leicht nachzuvollziehen, dass es eine neue Art der Kommunikation braucht. Um einen Fortschritt zu erzielen, ist es notwendig, die der Erkrankung zugrunde liegenden biologischen Prozesse besser zu verstehen. Zum direkten Vergleich mit konventionellen Angiographien wurde ein Verfahren zur automatischen Generierung von Projektionsansichten aus den CT-Daten entwickelt.

Das Pyoderma gangraenosum PG ist eine seltene, inflammatorische destruktiv-ulzerierende neutrophile Erkrankung mit weitgehend unklarer Pathophysiologie. In dieser Studie wurden die potenziell relevanten Kofaktoren und Begleiterkrankungen von Patienten mit PG aus drei dermatologischen Wundzentren in Deutschland differenziert ausgewertet. Quantitative Fragestellungen Tumorausdehnung, Infiltrationstiefe, etc. Nichtinterventionelle Studie bei erwachsenen Patientinnen mit leichter bis mittelschwerer Akne. Im Gesamtkollektiv wurden vier Melanome diagnostiziert, davon zwei zerebrale Melanome im Kindesalter, ein kutanes Melanom im Erwachsenenalter und eines, das sich als proliferierender Knoten erwies.

Gedanken und Experimente nach Einstein, Podolsky und Rosen. Physikalische Systeme sind im Prinzip separierbar. Diese erweisen einmal mehr die Quantenmechanik als richtige Theorie. Thoughts and Experiments after Einstein, Podolsky and RosenSince the advent of quantum mechanics there have been attempts of its interpretation in terms of statistical theory concerning individual classical systems. The very conditions necessary to consider hidden variable theories describing these individual systems as classical had been pointed out by Einstein, Podolsky and Rosen in 1.

Physical systems are in principle separable. If it is possible to. Nach der Applikation von HMP bzw. Die Inhibitoren Disulfiram und Ethanol der o.

Investigation of sites with groundwater contamination usually involves interpolation of point-based results across the aquifer under consideration. The range of autocorrelation thereby decides whether the quality of interpolation will be sufficient.

While there are investigations on the regional km scale, only a few publications exist for correlation lengths at a local 10s to s of m scale. This study investigates the accuracy of interpolation at the example of the BTEX-contaminated aquifer in Zeitz by means of variogram analysis and interpretation of. Der Rohingya - Konflikt:. Genese, aktuelle Situation und geopolitische Aspekte.

The Rohingya in Myanmar are often described as the most persecuted minority in the world. In the former Burma, the Rohingya are considered illegal immigrants and have been denied citizenship for decades. Since the end of August , more than , Rohingya from Rakhine State have fled to neighboring Bangladesh. While the public usually discusses the ethnic-religious and humanitarian causes and effects of the conflict, the political, economic and geopolitical interests of directly and indirectly involved actors also play a role. The contribution at hand argues that migration, especially of refugees, has received growing recognition in public and academic debates in the past few years.

It traces the reciprocal references to a highly dynamic research subject within migration scholarship, public discourse, and politics. It thereby highlights the value and risks of a space-related perspective. In addition to an outline of established and newly emerging research fields within geographic migration research, the contribution opens the debate on practical implications of the addressed topical challenges within the field.

Cornularia cornucopiae is a colonial coral whose polyps arise singly from stolons. In contrast with other octocrallia C. Therefore, tissue preparation for electron microscopic investigations can be performed. The presence of a calyx such as the theca of hydroids, in which the polyps may be completely retracted, is conspicuous. The calyx consists of three layers. The structure of the basal layer suggests massive collagen. The body wall is connected with the calyx by living desmocytes. The histology of the oral disc and the actinopharynx is identical.

The ventral side of the polyps bears the siphonoglyph. Below the pharynx the inner edges of the mesenteries are free and form the mesenterial filaments. The two ventral mesenteries differ from the others; the one is long and exhibits a large and heavily flagellated filament, the other is short and lacks a filament. The muscular system is represented by gastrodermal circular fibres in the body wall and by radial and longitudinal fibres in the septa; a large septal retractor muscle is missing. The sperm cells of Patella coerulea Patellacea , Monodonta turbinata, and Gibbula tumida Trochacea were investigated by means of transmission electron microscopy.

Their head contains an apical acrosome and a roundish nucleus followed by 4 or 5 mitochondria and a centriolar apparatus which consists of two centrioles, one of which bears a flagellum. The sperm cells of Monodonta and Gibbula are very similar to each other and differ mainly in size; Patella exhibits more differences very small acrosome, subacrosomal space, variable number of spherical mitochondria origin of spermic dimorphism?

The development of the sperm cells shows no peculiarities. Examples for genetic engineering are the transfer of nuclei between cells of higher animals and the introduction of heterologous DNA into bacteria by means of plasmids. The former approach will help to establish new ways in animal breeding, the latter provides bacterial cells that produce proteins of medical importance. The moral justification of related studies in man is still open, but the possible risks of gene technology can be coped with by adhering to proper safety regulations.

Migration und Flucht als Forschungsthemen der Geographie. Eine Standortbestimmung. For accurate planning of vertical borehole heat exchanger systems, knowledge of thermo-physical ground parameters is critical. This study reports laboratory-measured thermal conductivity and diffusivity values of Mesozoic sandstones Lower and Middle Buntsandstein from four wells.

The measurements were made on drill core using an optical scanning method. The mean thermal conductivities of the sandstones range between 2. The mean thermal diffusivity values range between 1. Thermal properties are closely related to the petrography and lithostratigraphy of the sandstones. Additionally, three temperature correction methods were applied for the purpose of evaluating the comparative accuracy and the correction schemes with respect to local in-situ conditions.

J Geophys Res, , are most suited for the respective sandstone data set. In doing so, they have not only departed from the Soviet-style education model, but also recognised that education constitutes a key issue in competition. Despite some economic problems, the education reforms in these countries have been regarded as part of a major effort at integrating themselves into the European sphere of knowledge. Many of the efforts and measures in education policy envisaged and carried out since the systemic change occurred have led not only to revitalizing national educational heritages, but also to the independent adoption of other European and international trends and topics in educational discourse.

Thereby, these states have proved to be considerably more innovative and flexible than the "older" members of the EU. The prospect of being taken up into the EU has probably helped accelerate the entire process. The present study focuses on some key overarching developments in the educational landscape of states in Central and Eastern Europe, even as it is apparent that these are proceeding along different paths at different speeds.

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. In particular, H. Duerbeck and 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.

Hatef Moeil VS Hans •Bad News• Lackner

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. Roessler on Lemaitre. Renn and T. 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.

The theory of generalized van der Waals forces by Lifshtz when applied to optically anisotropic media predicts the existence of a torque. In this work we present a theoretical calculation of the van der Waals torque for two systems. First we consider two isotropic parallel plates where the anisotropy is induced using an external magnetic field. The anisotropy will in turn induce a torque. The calculations of the torque are done in the Voigt configuration, that occurs when the magnetic field is parallel to the surface of the slabs.

The change in the dielectric function as the magnetic field increases has the effect of decreasing the van der Waals force and increasing the torque. Thus, the external magnetic field is used to tune both the force and torque. The second example we present is the use of the torque in the non retarded regime to align arrays of nano particle slabs. The torque is calculated within Barash and Ginzburg formalism in the nonretarded limit, and is quantified by the introduction of a Hamaker torque constant.

Calculations are conducted between anisotropic slabs of materials including BaTiO3 and arrays of Ag nano particles. Depending on the shape and arrangement of the Ag nano particles the effective dielectric function of the array can be tuned as to make it more or less anisotropic. We show how this torque can be used in self assembly of arrays of nano particles. Esquivel-Sirvent, G. Schatz, Phys. Chem C, , It has been common practice for decades, especially since the Convention on Biological Diversity was adopted in Rio , to protect certain marine areas, and the possibilities and scope of such marine protection measures have been widely discussed.

The Helsinki and Oslo-Paris Conventions for the protection of the marine environment, which are relevant for Germany, provide a framework for the establishment of marine protected areas. More protected areas are being added to the system. Information on the current status of both marine environmental protection systems is provided in this paper. In it, Feyerabend defends positivism as a progressive framework for scientific research in certain stages of scientific development.

He concludes that from time to time the abandonment of visualizability is crucial for progress in physics, as it is conducive to major theory change, illustrating the point on the basis of advances in atomic theory.

Grienberger studied in Prague and Vienna and succeeded his tutor, Christopher Clavius, as a professor of mathematics at the Roman College. Grienberger gave lectures in astronomy in order to prepare fellow Jesuits for their missionary work in China and constructed the equatorial set-up of the telescope. Among his works is a list of fixed stars, and he even worked in the science of optics.

Grienberger sympathized with Galileo's theory of motion but was told to defend the Aristotelian view by the Father General of the Jesuits, Claudio Aquaviva. Grienberger died on March 11, , and is buried in Rome. Electron acceleration at localized wave structures in the solar corona German Title: Elektronenbeschleunigung an lokalen Wellenstrukturen in der Sonnenkorona. While gaining energy from the whistler wave field, the electrons reach the shock front and, subsequently, a major part of them are reflected back into the upstream region, since the shock accompanied with a jump of the magnetic field acts as a magnetic mirror.

Co-moving with the whistlers now, the reflected electrons are out of resonance and hence can propagate undisturbed into the far upstream region, where they are detected in terms of type II metric radio bursts. In summary, the kinetic energy of protons is transfered into electrons by the action of localized wave structures in both cases, i.

Jahrhunderts zu befassen. Genetics Home Reference: van der Woude syndrome. What is the prognosis of a genetic condition? Genetic and Rare Diseases Information Center Frequency Van der Woude syndrome is believed to occur in 1 in 35, to 1 in , people, based on data from Europe and Asia. Van der Woude syndrome Der homologs are ubiquitously found in eubacteria. Conversely, very few are conserved in eukaryotes, and none is conserved in archaea. In the present study, to verify their conserved role in bacterial 50S ribosomal subunit biogenesis, we cloned Der homologs from two gammaproteobacteria, Klebsiella pneumoniae and Salmonella enterica serovar Typhimurium; two pathogenic bacteria, Staphylococcus aureus and Neisseria gonorrhoeae; and the extremophile Deinococcus radiodurans and then evaluated whether they could functionally complement the E.

Only K. Typhimurium Der proteins enabled the E. Sucrose density gradient experiments revealed that the expression of K. Typhimurium Der proteins rescued the structural instability of 50S ribosomal subunits, which was caused by E. To determine what allows their complementation, we constructed Der chimeras. We found that only Der chimeras harboring both the linker and long C-terminal regions could reverse the growth defects of the der -null strain.

Our findings suggest that ubiquitously conserved essential GTPase Der is involved in 50S ribosomal subunit biosynthesis in various bacteria and that the linker and C-terminal regions may participate in species-specific recognition or interaction with the 50S ribosomal subunit. However, to date, its precise role in ribosome biogenesis has not been. Contends that education was an important instrument of social change during the French Revolution.

Hydrogeologische Erkundung von Grundwasser in der ariden und vulkanisch aufgebauten Westkordillere Boliviens. An area of km2 in the arid western cordillera of Bolivia was geologically and hydro-geologically surveyed for the purpose of determining locations for borehole drilling in the framework of groundwater reconnaissance. Vertical geoelectrical resistivity soundings were applied to identify areas at depth in which aquifers with a sufficient thickness of fresh groundwater can be expected. A chemical and isotopic inventory of the regionally occurring groundwater revealed the presence of meteorically-recharged fresh and thermal waters as well as highly mineralized waters from fumaroles and a deep reservoir.

Due to their chemical and isotopic composition, the latter group shows influences of juvenile water. Carbon fourteen dating performed on the fresh and thermal waters indicates that they were recharged during the last pluvial phase, about 10, years ago. Extremely low contents of tritium of about 0. Christoph Rothmann and Copernicanism. German Title: Christoph Rothmann und der Copernicanismus.

Christoph Rothmann belonged to the first convinced adherents of heliocentric cosmology. Rothmann also vehemently defended his concepts in a letter to Tycho Brahe dating from September, , in which he rejected both the old geocentric and Brahe's geoheliocentric system. 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: i the interpretation of natural isotope depth-profiles and subsequent approximation of recharge using empirical relationships and ii the use of deuterium-enriched water 2H2O as tracer.

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.

The behavior of the periods of the tree stars from to is described here. Die Bilder der populaeren Astronomie des Today, popularisation of science also means "pretty pictures": images that accompany articles in magazines and webpages, or are squeezed between the covers of so-called coffee-table books, and the reviewer pleads guilty to having added to this growing pile. But how did this "disease" came into existence? Susanne Utzt, a manager, journalist and student in the history of sciences, has dedicated her master thesis to the investigation of the growing influence of such pictures in the popularisation of astronomy.

She has analyzed French and German popular texts by Arago, Guillemin, Flammarion, as well as Littrow, Maedler and Max Wilhelm Meyer that mainly appeared in the second half of the 19th century. Earlier astronomy books just had a few foldout pages with mathematical figures, as the author exemplifies by Littrow's first edition of "Die Wunder des Himmels" of But Flammarion with his "Astronomie Populaire", changed everything: 51 "art pages" and more than figures in the text made it a true picture book, and about a third of Utzt's work is dedicated to its analysis. In passing, it should be noted that the first edition of Flammarion's book did not yet contain the "art pages"; the author quotes such pages and text figures according to a German edition of Besides sober diagrams illustrating the solar system, and telescope drawings showing planetary surfaces and the structure of the solar photosphere, Flammarion includes poetic illustrations like a couple at the seashore at sunset; a scene showing dying Copernicus, already flanked by two angels, as he receives a copy of his De Revolutionibus; or a painting showing a flock of mammoths in an ancient landscape.

In most cases, the images are chosen to illustrate the text, but sometimes the text "makes a detour" to permit the inclusion of a pretty picture. Flammarion's book contains drawings illustrating the sphericity of the earth, which appeared in almost identical form in Apian's Cosmography of , and it includes images that became only a reality after space travel to the planets of the solar system became possible: thus Flammarion's images probe the past and the future, they cover a time interval of about years!

I think that there is a direct route from Flammarion's images "Jupiter, as seen from one of its moons" or "The rings of Saturn, as seen from Saturn", to the space art of Chesley Bonestell, as it appeared in the early s in the book "The Conquest of Space" by Willy Ley, as well as in popular journals.

Besides national prestige to be superior in rocketry and space travel, it was the fantasy and enthusiasm of the general public, as spurred by paintings like those of Bonestell, that made the space missions and the planetary exploration of the last decades possible. In , a certain Father Schlosser expressed his fear that the flood of images would lead to a loss of fantasy, to sensationalism and superficiality.

In modern society, illustrated newspapers, magazines and television may really have caused such a scientific analphabetism and superficial knowledge in wide circles. On the other hand, Wilhelm Foerster expressed the hope that the layman can be stimulated by sensual pleasures in his pursuit of insight, and even to a collaboration in science, and his hope was also fulfilled: nowadays, more hobby and professional scientists are active than in past times; "hobby science", if done in a professional way, can form a valuable supplement to astronomical science; and honestly, how many present-day astronomers have arrived at their profession by watching astronomical TV programs, reading science fiction novels, or illustrated astronomy books that they once received as a gift?

Utzt states that knowledge is generated and transmitted more and more by images, and propagated to the public by means of visualisations. Thus, a critical investigation of the influence of such images is needed, and the historical knowledge of the practice of visualisations in science and popularisation can form a basis for such a study. The somewhat slim volume of this series is embellished with 35 illustrations.

It offers interesting insights in the development of illustrations in popular scientific books, their use, and also sometimes their failure. It also inspires the reader to embark on further studies where the author, because of lack of source material, because of self-imposed limits of investigation, or perhaps simply because of lack of time, has halted.

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.

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. In urban areas of the Swiss Alps the use of geothermal energy from several hundred meters depth becomes increasingly important. For this mainly open systems have priority. This work presents the first insights in the prospection and characterisation of the so far unexplored, utilizable, and abundant Aquifer of the Arosa Dolomites.

Besides the use of established methods and techniques, such as seismic measurements, an exploration drilling, borehole geophysical measurements, and pumping tests, the application of the KARSYS-approach for geological and conceptual hydrogeological 3D-modelling of the aquifer is illustrated. In addition, the development of a viewer for 3D-visualization of drillings is documented.

The hydrogeological and metrological approaches allow a lithological facies differentiation of the Arosa Dolomites, and a differentiation of the fractured and karstified areas within the aquifer. The results represent the basis for advanced findings optimizing and risks minimising exploration and drilling planning, and for sustainable utilization planning.

The title compounds have been prepared and their Raman spectra recorded. The Raman spectra of the Calcium, Strontium and Barium compounds indicate symmetry splitting, therefore the P2S frequencies are assigned with C2h symmetry. Identifizierung der Nitratabbauprozesse und Prognose des Nitratabbaupotenzials in den Sedimenten des Hessischen Rieds.

Microbial denitrification contributes significantly to the mitigation of nitrate contamination in sedimentary aquifers by reducing nitrate coupled to the consumption of organic carbon heterotrophic and iron sulphides like pyrite autotrophic. However, these phases are often only present in trace amounts and can become depleted, so that denitrification will eventually cease. In order to implement measures within the EC-Water Framework Directive, we investigated the denitrification potential and the denitrification processes in the sediments of the Hessian Ried.

The reduction potential was quantified and characterized by solid-phase analyses of drill core samples. Depth-oriented investigations of hydrochemistry i. Despite low sulphide contents max. The results can be used to delineate risk areas, downstream of which denitrification can be expected to cease in the near future. Karl Schwarzschild and the professionalization of astrophysics.

Professionalization is characteristic for physics and astronomy since , and forms the basis for their rapid evolution in the 20th century. Karl Schwarzschild's contributions to professionalization of astronomy are presented: the introduction of course lectures in a repeating cycle, a permanent astrophysical laboratory, a tight connection between teaching and research, simulations and suggestions for astronomy at high schools and for the training of high school teachers, an interest in international organisation, and the initiative and planning of a southern observatory.

Response to van der Meer. In our recent Current Biology paper [1], we describe an ocean warming experiment in which we manipulated the temperature of panels set on the seafloor to provide a realistic and relevant indication of how benthic communities may change under future ocean warming. In his correspondence, Jaap van der Meer [2] questions our methods and provides alternative analyses which lead him to conclude that our observed increases in growth rate were in fact much lower and in accordance with previous studies from temperate zones.

We provide justification for our use of absolute growth rate, justification for not using instantaneous growth rate or a measure of growth in proportion to previous growth and encourage the on-going discussion of how to measure and compare growth rates. Published by Elsevier Ltd. The Forced van der Pol Equation. In doing so, many striking and interesting trajectories can be discovered and phenomena such as frequency entrainment,….

Power networks have to withstand a variety of disturbances that affect system frequency, and the problem is compounded with the increasing integration of intermittent renewable generation. Following a large-signal generation or load disturbance, system frequency is arrested leveraging primary frequency control provided by governor action in synchronous generators.

In this work, we propose a framework for distributed energy resources DERs deployed in distribution networks to provide supplemental primary frequency response. Particularly, we demonstrate how power-frequency droop slopes for individual DERs can be designed so that the distribution feeder presents a guaranteed frequency-regulation characteristic at the feeder head. Time-domain simulations for an illustrative network composed of a combined transmission network and distribution network with frequency-responsive DERs are provided to validate the approach.

Sozialindex und gewichtenregeling. In Germany and the Netherlands spatial information about the social structure of the inhabitants is used for the coordination of financial and human resources in the local school-system. The aim is to reduce educational inequalities by taking the social context of the schools into account. The article explains two approaches. In North Rhine-Westphalia Germany a so called Sozialindex is used to distribute additional teachers to municipalities with difficult social surroundings. The Dutch government uses an instrument to give each pupil a weight gewichtenregeling depending on the specific educational background.

Combined with an evaluation of the school location an additional budget, if necessary, will be payed. Developments and consequences of school profiling in general-education schools in selected European countries and perspectives for implementation in Germany - The development of a school programme, e. This paper focuses on the background and the significance of this development in school politics but also on the potential and the challenges which come with the profile formation of schools on an individual as well as systemic basis.

Furthermore, the author introduces and discusses examples for the profile formation of schools and classes by looking at concrete projects. After that, recommendations are given for school programme work in individual schools. The focus is especially on German-speaking countries such as Germany, Austria and Switzerland.

Discusses the extent to which five popular English teaching texts distinguish between active and passive vocabulary in learning English, and pleads offering concrete suggestions for more attention to the vocabulary aspect in constructing teaching textbooks for junior high schools.

Analysing some special conditions of this black hole with geometrothermodynamical method, we find a good correlation with ordinary cases according to the state equation. Textlinguistik und Schulunterricht. Am Beispiel der Behandlung der indirekten Rede im Englischen. Compares sentence grammar with text linguistics, giving a survey of the treatment of indirect discourse in school grammars, and finding them inadequate.

Recommends rules derived from text linguistics in spite of their greater complexity, because they do not hold the student to mechanical recasting of sentences. The Ruhr area has advanced to the largest university region in Germany - often unnoticed within and outside. At the same time scientific institutions have become a major economic factor. Because of the higher and extra-university research institutions about 2.

Additional million euros result in revenues of many branches such as trade, housing, gastronomy sector, handcraft industry etc. It should not be underestimated that higher and extra-university research institutions generate with their research activities particular funding from the European Union or the rest of Germany for benefit of the region. Each euro spent by the state government for basic funding creates 39 cents third-party funding.

These regional-economic effects result in noticeable employment impacts within the region. Around 25, people are directly employed in higher and extra-university research institutes or student unions Studierendenwerke , about 22, jobs in other economic sectors are ensured or created by the induced demand. Science has thus become an important economic factor and represents an essential counterbalance to employment decline in shrinking industries of the region. The specific inclusion of science in a regional development strategy and targeted relining with appropriate measures to strengthen the science creates therefore an effective starting point for the design of structural change.

Valid models for estimating nitrate emissions from agriculture to groundwater are an indispensable forecasting tool. A major challenge for model validation is the spatial and temporal inconsistency between data from groundwater monitoring points and modelled nitrate inputs into groundwater, and the fact that many existing groundwater monitoring wells cannot be used for validation. For this purpose, groundwater monitoring wells were sampled in Lower Saxony. The results show a good agreement between both methods for glacial outwash plains and moraine deposits.

Although the nitrate degradation processes in groundwater and soil merge seamlessly in areas with a shallow groundwater table, the DENUZ model only calculates denitrification in the soil zone. To account for high temporal and spatial variability of nitrate emissions into groundwater, a large number of groundwater monitoring points must be investigated for model validation.

Theory of coherent van der Waals matter. We explain in depth the previously proposed theory of the coherent van der Waals cvdW interaction, the counterpart of van der Waals vdW force, emerging in spatially coherently fluctuating electromagnetic fields. We show that cvdW driven matter is dominated by many-body interactions, which are significantly stronger than those found in standard van der Waals vdW systems.

From a microscopic theory we show that the anisotropic cvdW many-body interactions drive the formation of low-dimensional structures such as chains, membranes, and vesicles with very unusual, nonlocal properties. In particular, cvdW chains display a logarithmically growing stiffness with the chain length, while cvdW membranes have a bending modulus growing linearly with their size.

We argue that the cvdW anisotropic many-body forces cause local cohesion but also a negative effective "surface tension. Modeling of DER were studied based on a system point of view, the article initially proposed a CIM extended information model. By analysis the basic structure of the message interaction between DMS and DER , a bidirectional messaging mapping method based on data exchange was proposed.

German Title: H. Schumacher played an outstanding role among the astronomers of the first half of the 19th century. Altona, his place of activity, belonged to the kingdom of Denmark. This paper analyses these questions on the basis of previously unused archival sources and discusses also Schumacher's life and his relations to the royal dynasty.

The Group 1 mite allergens, Der f 1 and Der p 1, are potent allergens excreted by Dermatophagoides farinae and Dermatophagoides pteronyssinus, respectively. The human IgE antibody responses to the Group 1 allergens show more cross-reactivity than the murine IgG antibody responses which are largely species-specific.

Here, we report the crystal structure of the mature form of Der f 1, which was isolated from its natural source, and a new, high-resolution structure of mature recombinant Der p 1. Unlike Der p 1, Der f 1 is monomeric both in the crystalline state and in solution. Although Der p 1 and Der f 1 share extensive sequence identity, comparison of the crystal structures of both allergens revealed structural features which could explain the differences in murine and human IgE antibody responses to these allergens.

There are structural differences between Der f 1 and Der p 1 which are unevenly distributed on the allergens' surfaces. This uneven spatial arrangement of conserved versus altered residues could explain both the specificity and cross-reactivity of antibodies against Der f 1 and Der p 1. Probleme bei der Digitalisierung analoger Messwerte. Hier soll auf einige Probleme, die durch die Umsetzung entstehen, aus messtechnischer Sicht eingegangen werden.

Scaling laws for van der Waals interactions in nanostructured materials. Van der Waals interactions have a fundamental role in biology, physics and chemistry, in particular in the self-assembly and the ensuing function of nanostructured materials. Here we utilize an efficient microscopic method to demonstrate that van der Waals interactions in nanomaterials act at distances greater than typically assumed, and can be characterized by different scaling laws depending on the dimensionality and size of the system.

Specifically, we study the behaviour of van der Waals interactions in single-layer and multilayer graphene, fullerenes of varying size, single-wall carbon nanotubes and graphene nanoribbons. As a function of nanostructure size, the van der Waals coefficients follow unusual trends for all of the considered systems, and deviate significantly from the conventionally employed pairwise-additive picture.

We propose that the peculiar van der Waals interactions in nanostructured materials could be exploited to control their self-assembly. Diese im Mittelalter neu erprobte Form basierte auf der Entdeckung des Blutkreislaufes durch William Harvey Presents the so-called Humboldt Service taped segments from the BBC World Service news broadcasts, supplemented with exercise sheets and instructions for the teacher , which was devised by teachers of English in Berlin, and is obtainable from the Business School English Teachers' Association.

Since decolonization till todays "New Odyssey" - the current European refugee crisis— Kingsley we witnessed an unhindered and unrestricted migration to Europe from Africa south of the Sahara. Regulated migration was even promoted for medical staff, soldiers and seamen. This was induced by a shortage of qualified staff in receiving ex-colonial powers and the need maintaining mercenary armies for todays international conflicts. Political refugees were often hoped to form new western-friendly governments in cases of socialist Ethiopia and dictatorial regimes in esp.

Todays migration out of Africa south of the Sahara is often caused by political and humanitarian crises, but specifically accelerated by the long-lasting negligence of donors for small-scale agricultural development. Land grabbing and the challenge to bring millions of youth with formal training into a meaningful occupation are seen as further important causes of rural outmigration. A "mismatch" between training programs offered especially by international development agencies and training needs for employability is also causing mass-unemployment of youth.

An alignment of future development programming with the needs of the poor to assure a "right to stay" should be addressed by international policy makers with highest priority. The small town of Altena is among the fastest-shrinking cities in western Germany and has recently attracted national and international attention due to its "welcoming culture" for refugees.

This can be understood within the context of the town's strategic urban development policies aiming to counter the demographic change. This article argues that a regeneration strategy directed towards immigration and integration can offer a chance for shrinking cities but is simultaneously faced with considerable challenges and uncertainties, which could be dealt with through an "integrative approach" to urban development. Unternehmerische Verantwortung in der Stadt- und Regionalentwicklung. Firms assume increasing importance within co-operative modes of regional and urban governance.

Further to just filling gaps left by the retreat of the welfare state, firms recognise the impact of their regional and local business environment on their performance, especially when it comes to attracting and retaining highly-skilled personnel. As an introduction to this issue, this contribution introduces the basic concept of corporate social responsibility and its regional variation, corporate regional responsibility.

While planning tracer tests, uncertainties in geohydraulic parameters should be considered as an important factor. Neglecting these uncertainties can lead to missing the tracer breakthrough, for example. One way to consider uncertainties during tracer test design is the so called ensemble forecast. The applicability of this method to geohydrological problems is demonstrated by coupling the method with two analytical solute transport models.

The algorithm presented in this article is suitable for prediction as well as parameter estimation. The parameter estimation function can be used in a tracer test for reducing the uncertainties in the measured data which can improve the initial prediction. The algorithm was implemented into a software tool which is freely downloadable from the website of the Institute for Groundwater Management at TU Dresden, Germany.
