Therapeutic Uses of Botulinum The Statistical Analysis of Recurrent Toxin Events Recurrent event data arise in diverse fields such as medicine, public health, insurance, social science, economics, manufacturing and reliability. The purpose of this book is to present models and statistical methods for the analysis of recurrent event data. No single comprehensive treatment of these areas currently exists. The authors provide broad but detailed coverage of the major approaches to analysis, while also emphasizing the modeling assumptions that they are based on.

Thus, they consider important models such as Poisson and renewal processes, with extensions to incorporate covariates or random effects. More general intensity-based models are also considered, as well as simpler models that focus on rate or mean functions. Parametric, nonparametric and semiparametric methodologies are all covered, with clear descriptions of procedures for estimation, testing and model checking. Observation schemes giving incomplete or selective data.

The editors explore how this novel compound fits into a wide variety of treatment algorithms across medical subspecialties. Each chapter focuses on a particular symptom and explains how botulinum toxin is currently used for treatment. The chapter authors are all leaders in their fields and are respected for their progressive approach to treatment. Physicians will benefit not only from those chapters devoted to their particular sub-specialty, but from the inspiring success resulting from the use of botulinum toxin in other patient populations.

Besides a few short notices and book reviews, the book contains eight major articles, which deal with astronomical topics covering the time from the 16th to the 19th centuries.

The first article by Michael Weichenhan Berlin deals with "the invention of the disk-shaped earth: a chapter of Copernican apologetics". The author shows that the concept of a "disc-shaped Earth" was by no means widespread in the middle ages, but restricted to the father of the church Lactantius and some adherents.

Nevertheless, it was used by adherents of Copernicus to show the absurd consequences of a strictly literal biblical interpretation -- here concerning the Earth's shape, disc versus sphere, there the geocentric versus the heliocentric system. This thorough philosophical study is followed by two very short articles. The result is that standard deviations are 80 arcseconds for Saturn and 89 arcseconds for Jupiter and Mars, an unexpectedly poor result in view of the general opinion that Tycho was famous for his precision work.

While he was inclined to Galilei early on, he was forced to propagate Aristotelian doctrine. The brief article is very concise, but extremely tiresome to read 3 pages of pure text are embellished by. Die Leitlinie stellt allgemeine Aspekte der Pharmakokinetik sowie der regulatorischen Begrifflichkeiten dar. Die Bedeutung der galenischen Grundlagen und die Problematik bei einer Substitution gegeneinander verschiedener Grundlagen werden dargestellt.

In various bacteria, Zur , a zinc-specific regulator of the Fur family, regulates genes for zinc transport systems to maintain zinc homeostasis. It has also been suggested that Zur controls zinc mobilization by regulating some ribosomal proteins. The antibiotic-producing soil bacterium Streptomyces coelicolor contains four genes for Fur family regulators, and one named zur is located downstream of the znuACB operon encoding a putative zinc uptake transporter.

Purified Zur existing as homodimers bound to the znuA promoter region in the presence of zinc, confirming the role of Zur as a zinc-responsive repressor. This finding reflects a link between thiol-oxidizing stress and zinc depletion. We determined the Zur -binding sites within znuA and rpmG2 promoter regions by footprinting analyses and identified a consensus inverted repeat sequence TGaaAatgatTttCA, where uppercase letters represent the nucleotides common to all sites analyzed. This sequence closely matches that for mycobacterial Zur and allows the prediction of more genes in the Zur regulon.

Born in Gelsenkirchen-Buer in Germany on March 11th, , Professor Harald zur Hausen, Emeritus Professor of Virology at the University of Freiburg and Nobel Prize Laureate in Physiology or Medicine for his discovery of human papillomavirus HPV , which causes cervical cancer, believes that good knowledge of virological methods and diagnostic possibilities are an asset for all young paediatricians. Professor zur Hausen considers that the creation of an educational platform on Paediatric Virology is definitely very beneficial for young paediatricians, as this will greatly enhance their knowledge in the field of Virology.

He very actively advocates the vaccination of boys for the eradication of HPV infection and emphasises that male HPV vaccination should be included into the current vaccination programmes. He would have certainly considered Dr George N. In the context of the 3rd Workshop on Paediatric Virology, which will be held in Athens, Greece, on October 7th, , Professor zur Hausen will give his plenary lecture on 'Paediatric Virology and Oncology: Virus persistence and the important first years of life'.

Die Architektur besteht aus mehreren dedizierten Recheneinheiten zur parallelen Verarbeitung rechenintensiver Bildverarbeitungsverfahren und ist mit einem RISC-Prozessor verbunden. This paper presents the mapping of a video-based approach for real-time evaluation of angular histograms on a modular coprocessor architecture.

The architecture comprises several dedicated processing elements for parallel processing of computation-intensive image processing tasks and is coupled with a RISC processor. A configurable architecture extension, especially a processing element for evaluating angular histograms of objects in conjunction with a RISC processor, provides a real-time classification. Depending on the configuration of the architecture extension, 3 to 12 look-up tables are required for a Xilinx Virtex-5 FPGA implementation.

This paper presents an account of how I developed the Dialogos approach to practical philosophy through action inquiry research. Core perspectives, traditions and purposes involved in the action…. Streptomyces coelicolor contains paralogous versions of seven ribosomal proteins S14, S18, L28, L31, L32, L33, and L36 , which differ in their potential to bind structural zinc. Zur controls the expression of three transcriptional units including rpmG2, rpmE2, rpmB2, rpsN2, rpmF2, and possibly rpsR2.

Zur also controls the expression of the znuACB operon, which is predicted to encode a high-affinity zinc transport system. Zinc-responsive regulation of alternative ribosomal protein genes in Streptomyces coelicolor involves zur and sigmaR. We show that the level of expression of four transcriptional units encoding C - proteins is elevated under conditions of zinc deprivation.

Surprisingly, the zinc-responsive control of the rpmG3-rpmJ2 operon is dictated by sigma R , a sigma factor that was previously shown to control the response to disulfide stress in S. The induction of sigma R activity during zinc limitation establishes an important link between thiol-disulfide metabolism and zinc homeostasis. Strom hinausgehen.

The 15th volume of the Acta Historica Astronomiae is at the same time the fifth collection of essays on the history of astronomy Beitraege zur Astronomiegeschichte, Band 5 , edited by the historians of astronomy W. Besides a few short notices and book reviews, the book contains 11 major articles, which deal with astronomical topics covering the time from the 16th to the 20th centuries.

The first article, on the analysis and interpretation of historical horoscopes as a source of the history of science, is based on the inaugural lecture of its author, Guenther Oestmann. After a general introduction, which deals with the principles of horoscope making, the author discusses the horoscope of Count Heinrich Ranzau , the Danish governor of Schleswig-Holstein, who was a friend of Tycho Brahe. Oestmann shows that the astronomical-mathematical basis of such a horoscope can be reconstructed and interpreted.

However, it is hardly possible to gain an insight in the process how the interpretation of a horoscope was done in detail. The second and third articles, by Franz Daxecker, deal with Athanasius Kircher and Christoph Scheiner, two catholic astronomers of the 17th century. Kircher's Organum Mathematicum is a calculating device that can be used in the fields of arithmetic, geometry, chronology, astronomy, astrology and others. The author provides extracts of the description of the Organum taken from a book by Caspar Schott, which deal with chronology and astronomy.

A photograph of the Organum indicates that this tool consists of a set of tables glued on wooden or cardboard, but details of its contents and applications remain pretty obscure for the reader - a few elaborated examples would have been helpful. The second paper deals with the life of Christoph Scheiner SJ, the co-discoverer of sunspots next to Galileo , after leaving Rome in - the year of the Galileo trial.

Scheiner spent his later years in the Austrian and. Extrakte auf Basis von Viscum album L. Parental stress is increased in clinical contexts e. In addition, parental stress can result in a biased parental perception of child's behavior and emotions. As expected, increased EBSK scores were overrepresented in the clinical sample.

Equilibrium models of one- and two-component satellite galaxies are created. The tidal influence of the Milky Way, which is modeled as a rigid external potential, is examined. A first set of simulations adopting originally spherically-symmetric, one-component satellites show that after elliptical deformation, a bar and tails of unequal length arise which change their morphology cyclically. By considering comparative simulations, the following phenomena are discovered: 1 High-density regions in the tails, 2 low-density zones around the core or bar, 3 an often concealed bar.

The overall morphology as function of time is analysed. The particles are lost from the core via the bar and move along certain morphologically characteristic structures into the tails. After deducing general quantities of the multi-component King model, three stable standard models of two-component satellite galaxies with different distributions of dark and visible matter are found. These models have a mass ratio of for baryonic to dark matter. Without restriction to the universality of the results, the Large Magellanic Cloud was taken as basic prototype for these models.

To choose the proper orbits, the tidal radius of the three-component model of the potential of the Galaxy is calculated both analytically and numerically. Then the simulations are analysed with the different behaviour of the components being the main focus of interest. Main results: 1 It is possible to detach a large fraction of dark matter but only a small amount of visible matter. Dark and visible matter may form different morphological structures. Some of these effects are just projection effects.

Zur Biologie des marinen Heterotardigraden Tetrakentron synaptae. Eggs and juveniles were found only in June and July, adults only from May to October. There are vagile males and stationary dwarf males. The dorsoventrally flattened body, an enlarged slimy epicuticle in females and dwarf males, the full set of claws also in juveniles, and the anus, which is in a dorsocaudal position, are indicative for an epizoic, sessile life.

The feeding of the nauplii is advanced by a marginal setule-crest of the labrum which prevents food-particles from being swept away. The oral appendages of the copepodites circumscribe a frustal space ventral to the mouth which facilitates uptake of food-particles.

The nauplii are not able to swim and perform stalking movements with their antennal endopodites. Good swimming ability as well as digging-in-behaviour and negative phototaxis of the copepodites indicate epi- as well as inbenthic mode of life. Several life-cycle characters are described.

With the discovery of arogenic acid two new pathways for the biosynthesis of phenylalanine and tyrosine have been revealed.

The occurrence of two, three, or four pathways for the biosynthesis of phenylalanine and tyrosine in microorganisms and plants may be a useful tool for taxonomic classifications. Investigations on enterobacteriaceae, pseudomonads, flavobacteria, streptomycetes, archaebacteria, and on Sphaerotilus, Trichococcus and Leptothrix species from bulking sludge are described. The possible role of arogenate in the evolution of the pathways for tyrosine and phenylalanine biosynthesis is discussed.

Planungsmodelle und Planungsmethoden. Anhaltspunkte zur Strukturierung und Gestaltung von Planungsprozessen. The topic of this article ist the question, in which phases oft he political planning process planners apply their methodological set of tools. That for the results of a research-project are presented, which were gained by an examination of planning-cases in learned journals.

Firstly it is argued, which model oft he planning-process is most suitable to reflect the regarded cases and how it is positioned to models oft he political process. Thereafter it is analyzed, which types of planning methods are applied in the several stages oft he planning process. The central findings: Although complex, many planning processes can be thouroughly pictured by a linear modell with predominantly simple feedback loops. Even in times of he communicative turn, concerning their set of tools, planners should pay attention to apply not only communicative methods but as well the classical analytical-rational methods.

They are helpful especially for the understanding of the political process before and after the actual planning phase. Zeitspiel ist keine Alternative - Warum der Wandel zur Pflicht wird.

Turbines reflect the signals of weather radar and other radar systems. As a result, building permit is refused for numerous new wind turbines, as the potential interference can not be reliably predicted. As a contribution to the improvement of this predictability, measurements are planned which aim at the high-frequency characterisation of wind energy installations. In this paper, a cost-effective FMCW radar is presented, which is operated in the same frequency band C-band as the weather radars of the German weather service. Here, the focus is on the description of the hardware design including the considerations used for its dimensioning.

In the Federal Republic of Germany there have in recent years been many varied encounters between Germans and representatives of other cultures, particularly those from Third World countries.

These have increasingly been organized with an awareness of global interdependence and have as a result opened the door to the influence of foreign cultures and to an unmistakeable movement in the direction of a multicultural society. An intercultural pedagogical approach and didactic theory are faced with the task of resolving the consequent problems related to education and training. The author firstly attempts to systematize as a typology the practice of learning as it occurs in intercultural encounters in so far as this relates to the Federal Republic of Germany.

Grundvoraussetzungen herzchirurgischer Einheiten zur Behandlung von Patienten mit angeborenen Herzfehlern. This document defines fundamental structures of congenital cardiac surgery departments in Germany. In Germany, pediatric cardiology and cardiac surgery facilities caring for patients with congenital cardiac defects are subject to certain regulations. For example, in the Federal Joint Committee implemented the resolution on Quality Assurance Measures in the Provision of Cardiac Surgical Care for Children and Adolescents directive congenital cardiac surgery which regulates structural and process quality compulsorily.

To date, fundamental and considerable differences of the respective departments persist.

Congenital cardiac surgery departments have to provide the whole spectrum of the cardiac surgical therapy from the neonate to the adult with congenital cardiac defects with the exception of heart transplantation continuously and with the appropriate experience. Furthermore, the departments have to prove their constant scientific activity and ensure that they facilitate education and training for the specialty certification in cardiac surgery.

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.

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: Fusionsforschung. 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: 1 grain-size analysis, 2 Kozeny-Carman approach, 3 permeameter tests and 4 flow rate experiments in large-scale tank experiments. 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. Chirurgie angeborener Herzfehler. In Deutschland werden jedes Jahr etwa 6.

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.

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: 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. 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. 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.

Table of contents

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. 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.
