Evaluating the bonding of two adhesive systems to enamel submitted to whitening dentifrices.

The aim of this study was to evaluate by micro-shear bond strength test, the bond strength of composite resin restoration to enamel submitted to whitening dentifrices. Forty bovine teeth were embedded in polystyrene resin and polished. The specimens were randomly divided into eight groups (n=5), according to the dentifrice (carbamide peroxide, hydrogen peroxide and conventional dentifrice) and the adhesive system (Prime & Bond 2.1 and Adper Single Bond 2). Dentifrice was applied for 15 minutes a day, for 21 days. Thirty minutes after the last exposure to dentifrice, the samples were submitted to a bonding procedure with the respective adhesive system. After that, four buttons of resin were bonded in each sample using transparent cylindrical molds. After 24 hours, the teeth were submitted to the micro-shear bond strength test and subsequent analysis of the fracture mode. Data were submitted to analysis of variance and Fisher's PLSD test (alpha = 0.05). The micro-shear bond strength showed no difference between adhesives systems but a significant reduction was found between the control and carbamide groups (p = 0.0145) and the control and hydrogen groups (p = 0.0370). The evaluation of the failures modes showed that adhesive failures were predominant. Cohesive failures were predominant in group IV The use of dentifrice with peroxides can decrease bonding strength in enamel.

Prevention of soil-transmitted helminth infection

Soil-transmitted helminths (STHs) form one of the most important groups of infectious agents and are the cause of serious global health problems. The most important STHs are roundworms (Ascaris lumbricoides), whipworms (Trichuris trichiura) and hookworms (Necator americanus or Ancylostoma duodenale); on a global level, more than a billion people have been infected by at least one species of this group of pathogens. This review explores the general concepts of transmission dynamics and the environment and intensity of infection and morbidity of STHs. The global strategy for the control of soil-transmitted helminthiasis is based on (i) regular anthelminthic treatment, (ii) health education, (iii) sanitation and personal hygiene and (iv) other means of prevention with vaccines and remote sensoring. The reasons for the development of a control strategy based on population intervention rather than on individual treatment are discussed, as well as the costs of the prevention of STHs, although these cannot always be calculated because interventions in health education are difficult to measure. An efficient sanitation infrastructure can reduce the morbidity of STHs and eliminates the underlying cause of most poverty-related diseases and thus supports the economic development of a country.

Jaw musculature of the Meiglyptini (Aves: Piciformes: Picidae)

The Meiglyptini comprise eight species of woodpeckers grouped into three genera, two of which contain three species ( Meiglyptes and Mulleripicus), while one genus includes two species ( Hemicircus). The purpose of this study is to describe the mandibular apparatus found in six species of Meiglyptini and to compare them with each other and with other woodpecker species. The results reveal a number of structures that are worth mentioning: (i) the components of the external mandibular adductor system of Hemicircus concretus, particularly the M. adductor mandibulae externus caudalis medialis, are underdeveloped compared with the other investigated species; (ii) the muscles of the internal mandibular system are structurally different among Meiglyptes species and are less developed, both in size and in structure, in H. concretus; (iii) the M protractor quadrati is vestigial in Meiglyptes species; (iv) the muscles of the protractor system of the quadrate are relatively undeveloped in H. concretus; (v) most of the muscles of the pterygoideus system are structurally differentiated in Meiglyptes species. It appears that the complexity of the mandibular apparatus is associated with the type of food consumed, as the apparatus of the frugivorous species H. concretus is markedly different from that of the insectivorous species. © 2012 The Royal Swedish Academy of Sciences.

Systematics of spiny-backed treefrogs (Hylidae: Osteocephalus): An Amazonian puzzle

Spiny-backed tree frogs of the genus Osteocephalus are conspicuous components of the tropical wet forests of the Amazon and the Guiana Shield. Here, we revise the phylogenetic relationships of Osteocephalus and its sister group Tepuihyla, using up to 6134 bp of DNA sequences of nine mitochondrial and one nuclear gene for 338 specimens from eight countries and 218 localities, representing 89% of the 28 currently recognized nominal species. Our phylogenetic analyses reveal (i) the paraphyly of Osteocephalus with respect to Tepuihyla, (ii) the placement of 'Hyla' warreni as sister to Tepuihyla, (iii) the non-monophyly of several currently recognized species within Osteocephalus and (iv) the presence of low (<1%) and overlapping genetic distances among phenotypically well-characterized nominal species (e.g. O. taurinus and O. oophagus) for the 16S gene fragment used in amphibian DNA barcoding. We propose a new taxonomy, securing the monophyly of Osteocephalus and Tepuihyla by rearranging and redefining the content of both genera and also erect a new genus for the sister group of Osteocephalus. The colouration of newly metamorphosed individuals is proposed as a morphological synapomorphy for Osteocephalus. We recognize and define five monophyletic species groups within Osteocephalus, synonymize three species of Osteocephalus (O. germani, O. phasmatus and O. vilmae) and three species of Tepuihyla (T. celsae, T. galani and T. talbergae) and reallocate three species (Hyla helenae to Osteocephalus, O. exophthalmus to Tepuihyla and O. pearsoni to Dryaderces gen. n.). Furthermore, we flag nine putative new species (an increase to 138% of the current diversity). We conclude that species numbers are largely underestimated, with most hidden diversity centred on widespread and polymorphic nominal species. The evolutionary origin of breeding strategies within Osteocephalus is discussed in the light of this new phylogenetic hypothesis, and a novel type of amplexus (gular amplexus) is described. © 2013 The Norwegian Academy of Science and Letters.

Paisagens urbanas: fotografia e modernidade na cidade de Belém (1846-1908)

Paisagens Urbanas: fotografia e modernidade na cidade de Belém (1846-1908) propõe uma discussão sobre os documentos fotográficos que serviam de instrumentos de propaganda dos governantes na última década do século XIX e no início do século XX. A linguagem visual desta dissertação permite mostrar a forma como os indivíduos se fizeram representar nos cenários urbanos, dando visibilidade aos tipos sociais que foram flagrados sutilmente pelas câmeras fotográficas a serviço da propaganda do governo que tinha por objetivo divulgar uma cidade moderna, revelando a intensidade e a rapidez com que desejava alcançar a modernidade, ao mesmo tempo em que traz a luz uma cidade de acordo com os modelos provenientes da Europa, percebe-se o registro de uma outra cidade que nos remete a espaços de convivência de diferentes realidades. A imagem fotográfica, assim como outras fontes e objetos visuais, constitui-se em importantes instrumentos de investigação histórica para identificar novos objetos e novos problemas. A contribuição deste estudo se ancora no uso da fotografia como principal documento de análise para produção historiográfica, entendendo que a fotografia representa um testemunho que “fala” do passado na intensidade que o historiador a questiona. Este estudo busca analisar a relação entre fotografia e cidade a partir da narrativa visual dos álbuns e relatórios de Belém que foram produzidos no período de 1898 a 1908. A interpretação dos álbuns, enquanto narrativa que visualiza uma cidade moderna, constituí-se em uma das estratégias metodológicas para abordagem do uso da fotografia como documento para o historiador, considerando que nesse tipo de documentação pode mostrar dados dispersos ou mesmo silenciados por outras fontes de pesquisas.

Artificial Immune Systems Applied to the Analysis of Structural Integrity of a Building

This paper presents the application of artificial immune systems for analysis of the structural integrity of a building. Inspired by a biological process, it uses the negative selection algorithm to perform the identification and characterization of structural failure. This paper presents the application of artificial immune systems for analysis of the structural integrity of a building. Inspired by a biological process, it uses the negative selection algorithm to perform the identification and characterization of structural failure. This methodology can assist professionals in the inspection of mechanical and civil structures, to identify and characterize flaws, in order to perform preventative maintenance to ensure the integrity of the structure and decision-making. In order to evaluate the methodology was made modeling a two-story building and several situations were simulated (base-line condition and improper conditions), yielding a database of signs, which were used as input data for the negative selection algorithm.

Molecular analysis of community-acquired methicillin-resistant Staphylococcus aureus isolated from skin and soft tissue infections, Botucatu Medical School, Brazil

Community acquired methicillin Staphylococcus aureus (CA-MRSA) was first reported in 1981, infecting people without risk factors. These strains harbor the Staphylococcal Cassette Chromosome mec (SCCmec) type IV, which contains the mecA gene codifying for methicillin resistance. CA-MRSA strains usually carry PVL (Panton-Valentine Leukocidin), a virulence factor responsible for tissue invasion, causing systemic infections and leading to serious complications. The aims of this work were to detect the mecA gene, SCCmec characterization and to detect the PVL gene of the S. aureus strains isolated from patients diagnosed with skin and soft tissue infections attending the Dermatology Service, of the Botucatu Medical School, Brazil. Among 127 collected samples, 66 (51.9%) were S. aureus and, from these, 7 (10.6%) harbored mecA gene, 3 (42%) with cassette type IV, and none of these samples carried the PVL gene, but it was detected in 10 (15.1%) samples of S. aureus methicillin sensitive (MSSA). Our study suggests the S. aureus strains that harbor PVL gene and MRSA are present in the community as important pathogens.

Biocompatibility of experimental Ti-30Ta implants with compromised primary stability: effect of TEA

Purpose: Ti-Ta alloys have high potential for dental application due to a good balance between high strength and low modulus. Absence of primary anchoring may occur when dental implants are installed immediately after tooth extraction. Tranexamic acid (TEA) is used to reduce fibrin degradation and can prevent early blood clot breakdown. The aim of this study was to evaluate the biocompatibility of Ti-30Ta implants associated or not with tranexamic acid and installed with compromised primary stability. Methods and materials: Fabricated were 20 implants of titanium ASTM F67 (Grade 4) and 20 implants of Ti-30Ta alloy with dimensions of 2.1 mm × 2.8 mm Ø. They were divided (n = 10) into Group I (Ti machined), Group II (Ti machined/tranexamic acid), Group III (Ti-30Ta alloy) and Group IV (Ti-30Ta/tranexamic acid) and were implanted in tibia (defects with 2.5 mm × 3.2 mm Ø) of 40 male rats (250 g). The surgical sites were rinsed with 5% tranexamic acid solution in Groups II and IV. The animals were euthanized at 45 days postoperative. The pieces were processed in methyl methacrylate (Stevenel's blue/Alizarin red). The percentage of peri-implant tissue repair was analyzed via images obtained by an optical microscope coupled to a digital camera using Leica software and Adobe Photoshop QWin. Data were analyzed statistically with a significance level of 5%. Results: Histomorphometric results showed 97.16% of bone-implant contact for group IV, 89.78% of bone contact for group III, 70.89% for group II and 61.59% of bone contact for group I. The statistical analyses demonstrated significant differences (P < 0.05) among group I and other groups. Conclusion: The results suggest that (a) Ti-30Ta promoted an increase of bone healing and apposition around implant; (b) tranexamic acid favored the stabilization of blood clot and bone formation.

Comparative Genome Analysis of Trichophyton rubrum and Related Dermatophytes Reveals Candidate Genes Involved in Infection

The major cause of athlete's foot is Trichophyton rubrum, a dermatophyte or fungal pathogen of human skin. To facilitate molecular analyses of the dermatophytes, we sequenced T. rubrum and four related species, Trichophyton tonsurans, Trichophyton equinum, Microsporum canis, and Microsporum gypseum. These species differ in host range, mating, and disease progression. The dermatophyte genomes are highly colinear yet contain gene family expansions not found in other human-associated fungi. Dermatophyte genomes are enriched for gene families containing the LysM domain, which binds chitin and potentially related carbohydrates. These LysM domains differ in sequence from those in other species in regions of the peptide that could affect substrate binding. The dermatophytes also encode novel sets of fungus-specific kinases with unknown specificity, including nonfunctional pseudokinases, which may inhibit phosphorylation by competing for kinase sites within substrates, acting as allosteric effectors, or acting as scaffolds for signaling. The dermatophytes are also enriched for a large number of enzymes that synthesize secondary metabolites, including dermatophyte-specific genes that could synthesize novel compounds. Finally, dermatophytes are enriched in several classes of proteases that are necessary for fungal growth and nutrient acquisition on keratinized tissues. Despite differences in mating ability, genes involved in mating and meiosis are conserved across species, suggesting the possibility of cryptic mating in species where it has not been previously detected. These genome analyses identify gene families that are important to our understanding of how dermatophytes cause chronic infections, how they interact with epithelial cells, and how they respond to the host immune response. IMPORTANCE Athlete's foot, jock itch, ringworm, and nail infections are common fungal infections, all caused by fungi known as dermatophytes (fungi that infect skin). This report presents the genome sequences of Trichophyton rubrum, the most frequent cause of athlete's foot, as well as four other common dermatophytes. Dermatophyte genomes are enriched for four gene classes that may contribute to the ability of these fungi to cause disease. These include (i) proteases secreted to degrade skin; (ii) kinases, including pseudokinases, that are involved in signaling necessary for adapting to skin; (iii) secondary metabolites, compounds that act as toxins or signals in the interactions between fungus and host; and (iv) a class of proteins (LysM) that appear to bind and mask cell wall components and carbohydrates, thus avoiding the host's immune response to the fungi. These genome sequences provide a strong foundation for future work in understanding how dermatophytes cause disease.

Modeling the gas and aqueous phase chemistry of the marine boundary layer

Ein eindimensionales numerisches Modell der maritimenGrenzschicht (MBL) wurde erweitert, um chemische Reaktionenin der Gasphase, von Aerosolpartikeln und Wolkentropfen zu beschreiben. Ein Schwerpunkt war dabei die Betrachtung derReaktionszyklen von Halogenen. Soweit Ergebnisse vonMesskampagnen zur Verfuegung standen, wurden diese zurValidierung des Modells benutzt. Die Ergebnisse von frueheren Boxmodellstudien konntenbestaetigt werden. Diese zeigten die saeurekatalysierteAktivierung von Brom aus Seesalzaerosolen, die Bedeutung vonHalogenradikalen fuer die Zerstoerung von O3, diepotentielle Rolle von BrO bei der Oxidation von DMS und dievon HOBr und HOCl in der Oxidation von S(IV). Es wurde gezeigt, dass die Beruecksichtigung derVertikalprofile von meteorologischen und chemischen Groessenvon grosser Bedeutung ist. Dies spiegelt sich darin wider,dass Maxima des Saeuregehaltes von Seesalzaerosolen und vonreaktiven Halogenen am Oberrand der MBL gefunden wurden.Darueber hinaus wurde die Bedeutung von Sulfataerosolen beidem aktiven Recyceln von weniger aktiven zu photolysierbarenBromspezies gezeigt. Wolken haben grosse Auswirkungen auf die Evolution und denTagesgang der Halogene. Dies ist nicht auf Wolkenschichtenbeschraenkt. Der Tagesgang der meisten Halogene ist aufgrundeiner erhoehten Aufnahme der chemischen Substanzen in die Fluessigphase veraendert. Diese Ergebnisse betonen dieWichtigkeit der genauen Dokumentation der meteorologischenBedingungen bei Messkampagnen (besonders Wolkenbedeckungsgrad und Fluessigwassergehalt), um dieErgebnisse richtig interpretieren und mit Modellresultatenvergleichen zu koennen. Dieses eindimensionale Modell wurde zusammen mit einemBoxmodell der MBL verwendet, um die Auswirkungen vonSchiffemissionen auf die MBL abzuschaetzen, wobei dieVerduennung der Abgasfahne parameterisiert wurde. DieAuswirkungen der Emissionen sind am staerksten, wenn sie insauberen Gebieten stattfinden, die Hoehe der MBL gering istund das Einmischen von Hintergrundluft schwach ist.Chemische Reaktionen auf Hintergrundaerosolen spielen nureine geringe Rolle. In Ozeangebieten mit schwachemSchiffsverkehr sind die Auswirkungen auf die Chemie der MBL beschraenkt. In staerker befahrenen Gebieten ueberlappensich die Abgasfahnen mehrerer Schiffe und sorgen fuerdeutliche Auswirkungen. Diese Abschaetzung wurde mitSimulationen verglichen, bei denen die Emissionen alskontinuierliche Quellen behandelt wurden, wie das inglobalen Chemiemodellen der Fall ist. Wenn die Entwicklungder Abgasfahne beruecksichtigt wird, sind die Auswirkungendeutlich geringer da die Lebenszeit der Abgase in der erstenPhase nach Emission deutlich reduziert ist.

Speciation of Pu(III) in the environmental system humic substances-groundwater-kaolinite

For the safety assessments of nuclear waste repositories, the possible migration of the radiotoxic waste into environment must be considered. Since plutonium is the major contribution at the radiotoxicity of spent nuclear waste, it requires special care with respect to its mobilization into the groundwater. Plutonium has one of the most complicated chemistry of all elements. It can coexist in 4 oxidation states parallel in one solution. In this work is shown that in the presence of humic substances it is reduced to the Pu(III) and Pu(IV). This work has the focus on the interaction of Pu(III) with natural occurring compounds (humic substances and clay minerals bzw. Kaolinite), while Pu(IV) was studied in a parallel doctoral work by Banik (in preparation). As plutonium is expected under extreme low concentrations in the environment, very sensitive methods are needed to monitor its presence and for its speciation. Resonance ionization mass spectrometry (RIMS), was used for determining the concentration of Pu in environmental samples, with a detection limit of 106- 107 atoms. For the speciation of plutonium CE-ICP-MS was routinely used to monitor the behaviour of Pu in the presence of humic substances. In order to reduce the detection limits of the speciation methods, the coupling of CE to RIMS was proposed. The first steps have shown that this can be a powerful tool for studies of pu under environmental conditions. Further, the first steps in the coupling of two parallel working detectors (DAD and ICP_MS ) to CE was performed, for the enabling a precise study of the complexation constants of plutonium with humic substances. The redox stabilization of Pu(III) was studied and it was determined that NH2OHHCl can maintain Pu(III) in the reduced form up to pH 5.5 – 6. The complexation constants of Pu(III) with Aldrich humic acid (AHA) were determined at pH 3 and 4. the logß = 6.2 – 6.8 found for these experiments was comparable with the literature. The sorption of Pu(III) onto kaolinite was studied in batch experiments and it was determine dthat the pH edge was at pH ~ 5.5. The speciation of plutonium on the surface of kaolinite was studied by EXAFS/XANES. It was determined that the sorbed species was Pu(IV). The influence of AHA on the sorption of Pu(III) onto kaolinite was also investigated. It was determined that at pH < 5 the adsorption is enhanced by the presence of AHA (25 mg/L), while at pH > 6 the adsorption is strongly impaired (depending also on the adding sequence of the components), leading to a mobilization of plutonium in solution.

La produzione cinematografica nel sistema economico-industriale italiano tra il 1908 e il 1914. Il caso della Milano Films

La tesi riguarda il processo evolutivo dell’industria cinematografica italiana dal momento della sua prima espansione (biennio1906-1908) fino allo scoppio della I guerra mondiale. In particolare il lavoro si è concentrato sulle vicende societarie e produttive di una delle maggiori case di produzioni attive in Italia nel periodo preso in esame: la Milano Films. Le ricerche relative alla società milanese hanno portato al rinvenimento di una cospicua quantità di documenti finora inediti, attraverso i quali è stato possibile ricostruire nel dettaglio la vicenda societaria e produttiva della casa di produzione. Lo studio ha inoltre analizzato le peculiarità specifiche che, tra il 1908 e il 1914, contraddistinguono la cinematografia italiana dal punto di vista degli assetti societari e finanziari, dell’organizzazione produttiva, delle strategie distributive e commerciali, attraverso un costante confronto con il complessivo quadro industriale italiano coevo e, in particolare, con quei settori produttivi considerati più all’avanguardia nei primi anni del Novecento.

Das moderne Buch: Harry Graf Kesslers Ästhetik der Lebenskunst im Spiegel der Großherzog Wilhelm Ernst Ausgabe deutscher Klassiker

Die Großherzog Wilhelm Ernst Ausgabe deutscher Klassiker wurde seit 1904 bis in die Zwanziger Jahre hinein im Insel Verlag in Leipzig publiziert. Die Buchreihe hat nicht nur für den Verlag und die Druckerei Poeschel in der sie gedruckt wurde eine ganze Reihe von Neuerungen nach sich gezogen, auch für den deutschen Buchmarkt hat die Klassikerausgabe einen Meilenstein bedeutet. Sie hat einige Eigenschaften des Taschenbuches vorweggenommen. Sie orientierte sich an der Qualität bibliophiler Buchpublikationen, aber war dennoch preislich erschwinglich. Zeitgenössische Klassikerausgaben erschienen zumeist mit einem Kommentar. Nicht so die Großherzog Wilhelm Ernst Ausgabe. Der Text wurde zwar von führenden Wissenschaftlern editiert, aber sie war dennoch unkommentiert. Der Text war in einer Jenson-Antiqua gesetzt obwohl die Debatte um individuell gestaltete Künstlerschriften und die Diskussion um die als deutsche Schrift begriffene Fraktur unter den wichtigsten Protagonisten des deutschen Buchgewerbes ihren Höhepunkt noch nicht erreicht hatte. Ziel für die Klassikerausgabe war darüber hinaus, das zur Jahrhundertwende leicht angestaubte Image der Stadt Weimar aufzupolieren. Über das Patronat des Großherzogs hinaus hätte man die Gewinne aus dem Verkauf der Bücher der Permanenten Ausstellung für die Anschaffung von modernen Kunstobjekten zur Verfügung stellen wollen, die unter der Leitung von Harry Graf Kessler stand. Sieht man den Inhalt der Werke der in der Klassikerreihe erschienen Dichter Goethe, Schiller und Körner in einem ästhetischen Kontext mit dem der Philosophen Schopenhauer und Kant, wird im Spiegel der Formalästhetik der Klassikerausgabe Graf Kesslers Bildungs- und Kulturbegriff erkennbar, der sich in den Jahren nach der Jahrhundertwende zu seinem Lebenskunstideal verdichtete. Der zerrütteten Existenz der Zeitgenossen, wie Friedrich Nietzsche sie beschrieben hatte, sollte der Inhalt der Ausgabe in seiner modernen Form eine moderne Wertehaltung entgegensetzen. Die Lektüre der Klassiker sollte den deutschen Philister „entkrampfen“ und ihm ein Stück der verloren geglaubten Lebensfreude wieder zurück bringen, in dem dieser auch die Facetten des Lebensleids als normal hinnehmen und akzeptieren lernte. Die Klassikerausgabe repräsentierte aus diesem Grund auch den kulturellen und politischen Reformwillen und die gesellschaftlichen Vorstellungen die der Graf für ein modernes Deutschland als überfällig erachtete. Die Buchreihe war aus diesem Grund auch ein politisches Statement gegen die Beharrungskräfte im deutschen Kaiserreich. Die Klassikerreihe wurde in der buchhistorischen Forschung zwar als bedeutender Meilenstein charakterisiert und als „wichtiges“ oder gar „revolutionäres“ Werk der Zeit hervorgehoben, die Ergebnisse der Forschung kann man überspitzt aber in der Aussage zusammenfassen, dass es sich bei der Großherzog Wilhelm Ernst Ausgabe um einen „zufälligen Glückstreffer“ deutscher Buchgestaltung zu handeln scheint. Zumindest lassen die Aussagen, die bisher in dieser Hinsicht gemacht wurden, keine eindeutige Einordnung zu, außer vielleicht der, dass die Klassiker von der englischen Lebensreform inspiriert wurden und Henry van de Velde und William Morris einen Einfluss auf ihre äußere Form hatten. Gerade die Gedankenansätze dieser Beiden nutzte Graf Kessler aber für eigene Überlegungen, die ihn schließlich auch zu eigenen Vorstellungen von idealer Buchgestaltung brachten. Da für Kessler auch Gebrauchsgegenstände Kunst sein konnten, wird das Konzept der Klassikerausgabe bis zur Umsetzung in ihrer `bahnbrechenden´ Form in das ideengeschichtliche und ästhetische Denken des Grafen eingeordnet. Die Klassiker werden zwar in buchhistorischen Einzeluntersuchungen bezüglich ihrer Komponenten, dem Dünndruckpapier, ihrem Einband oder der Schrifttype exponiert. In buchwissenschaftlichen Überblicksdarstellungen wird ihr Einfluss hingegen weniger beachtet, denn verschiedene Kritiker bezogen sie seit ihrem ersten Erscheinen nicht als deutsches Kulturgut mit ein, denn sie lehnten sowohl die englischen Mitarbeiter Emery Walker, Edward Johnston, Eric Gill und Douglas Cockerell wie auch ihre Gestaltung als „welsche“ Buchausgabe ab. Richtig ist, die Großherzog Wilhelm Ernst Ausgabe hatte dieselbe Funktion wie die von Graf Kessler in Weimar konzipierten Kunstausstellungen und die dortige Kunstschule unter der Leitung seines Freundes Henry van de Velde. Auch das für Weimar geplante Theater, das unter der Leitung von Hugo von Hofmannsthal hätte stehen sollen und die Großherzog Wilhelm Ernst Schule, hätten dieselben Ideen der Moderne mit anderen Mitteln transportieren sollen, wie die Großherzog Wilhelm Ernst Ausgabe deutscher Klassiker.
