Relations between the classification of endogenous psychoses by Leonhard, the doctrine of pathoclisis by Vogt and the neurological conception of system diseases
No full textOn the basis of 30 years of cowork with Leonhard it is attempted to enlighten the theoretical background of his classification of endogenous psychoses. Inspired by the conceptions of Wernicke and Kleist he explained the differentiation of symptomatology by the model of system diseases applying this in completing and improving the psychopathological classification. His ideas about the origin of a differentiated vulnerability of brain structures are very similar to the doctrine of pathoclisis of Vogt, although Leonhard did not use this term
The French Exile of Rudolf Leonhard 1933-1945
No full textRudolf Leonhard (* 1888) lebte und arbeitete seit 1928 als deutscher Dichter in Paris. Mit dem Beginn des Exils 1933 gab er seinen zurückgezogenen Lebensstil auf, verstärkte seine literatur-politische Arbeit und wurde Initiator und Mitbegründer der Interessenvertretung deutschsprachigen Schriftstellers im Ausland, des Schutzverbandes deutscher Schriftsteller in Paris. Trotz zum Teil völliger Mittellosigkeit entstanden in den ersten sechs Jahren des Exil eine Vielzahl von publizistischen Beiträgen, einige Erzählungen, eine Komödie und lyrische Arbeiten in deutscher und französischer Sprache; er reiste nach Spanien und arbeitete in Exilorganisationen mit. Auch während seiner Internierung ab September 1939 in dem Lager Stade Roland-Garros in Paris, in den Lagern Le Vernet, Les Milles und im Gefängnis von Castres gelang es Leonhard seinen Beruf des Dichters weiter auszuüben. Leonhard schuf in der Gefangenschaft ein großes diarisches und lyrisches Werk. Durch die Unterstützung seiner Ehefrau Yvette Prost-Leonhard, seiner Freunde und durch seine kontuierliche literarische Arbeit überlebte er die Internierung. Nach der geglückten Flucht aus dem Gefängnis von Castres arbeitete Rudolf Leonhard für die Résistance in Marseille. Nur wenige seiner Arbeiten konnten als illegale Schriften veröffentlicht werden; sie halfen dem im Untergrund lebenden Dichter jedoch in der besetzten Stadt Marseille zuüberleben. Nach seiner Rückkehr nach Paris im Jahre 1945, versuchte Rudolf Leonhard als Mittler zwischen der deutschen und der französischen Kultur zu wirken, was im Europa des beginnenden Kalten Krieges nicht mehr möglich war. Nach langer schwerer Krankheit remigrierte Rudolf Leonhard er 1950 in die DDR, wo er weder literarisch gewürdigt noch finanziell unterstützt wurde. Am 19. Dezember 1953 starb Rudolf Leonhard in Berlin. Sein Freund, Alfred Kantorowicz, schrieb in seinem Nachruf für Rudolf Leonhard: „Wir sind ihm viel schuldig geblieben.“ Daran hat sich bis in die Gegenwart nichts geändert.Since 1928 the German author Rudolf Leonhard (* 1888) took home in Paris. After being later officially forced into exile from 1933 on, Leonhard became a public figure by initiating and founding the „Interessenvertretung deutschsprachiger Schriftsteller im Ausland“, that had support and protection of German authors in Paris as incentive. Being incarcerated in several warcamps from September 1939 onwards (Stade Roland-Garros in Paris, Le Vernet, Les Milles) and in prison in Castres, Leonhard continued to be a very productive writer, being continously supported by his wife Yvette Prost-Leonhard and several friends. After escaping the prison in Castres Rudolf Leonhard worked for the Résistance in Marseille, only very few of his writings could be published though. Moving back to Paris in 1945 Leonhard tried to mediate between French and German culture. Seriously fallen ill he later was forced to remigrate. He moved to the DDR in 1950, yet without ever receiving financial support. Rudolf Leonhard died on 19. Dezember 195XXX in Berlin, recalled by his friend Alfred Kantorowicz as someone not recognized and supported enough at his lifetime
Microbiological evaluation of different reprocessing methods for cuffed and un-cuffed tracheostomy tubes in home-care and hospital setting
No full textBackground: Manufacturers’ recommendations on cleaning of tracheostomy tubes focus on general warning information and non-specific manual cleaning procedures. The aim of this experimental study was to evaluate different reprocessing methods and to determine the mechanical integrity and functionality of tracheostomy tubes following reprocessing.
Methods: Sixteen cuffed or un-cuffed tracheostomy tubes obtained from hospital in-patients were reprocessed using one of the following reprocessing methods: a) manual brushing and rinsing with tap water, b) manual brushing followed by disinfection with a glutaraldehyde solution, c) manual brushing followed machine-based cleaning in a dishwasher, and d) manual brushing followed by ultrasound cleaning in a commercially available ultrasound device. Microbial burden of the tubes before and after reprocessing was assessed by measurement of microbial colony-forming units per mL (CFU/mL) of rinsing fluid. After cleaning, tracheostomy tubes were investigated for loss of functionality.
Findings: Manual brushing and rinsing with tap water reduced microbial colonization in average by 102 CFU/mL, but with poor reproducibility and reliability. Complete microbial reduction was achieved only with additional chemical or machine-based thermal disinfection. Ultrasound sonification yielded no further microbial reduction after manual brushing.
Conclusion: Manual brushing alone will not result in complete eradication of microorganism colonising cuffed or un-cuffed tracheostomy tubes. However, manual cleaning followed by chemical or thermal disinfection may be regarded as safe and reproducible reprocessing method. If a machine-based reprocessing method is used for cuffed tubes, the cuffs’ ventilation hose must be secured in a safe position prior to thermal disinfection
August Strindberg through the eyes of Karl Leonhard: A dialogue of cultures between Germany and Sweden
No full textThe present article is an attempt to bring together anthropology, literary science
and psychiatry with the aim to consider how life and work of August Strindberg
(1849–1912) is perceived in the last opus of the well-known German psychiatrist Karl
Leonhard (1904–1988), the author of the book Accentuated Personalities, which is very
well-known for the Russian reader. His views and evaluations form a bright period in
the history of the reception of the works of the Swedish writer in Germany and can be
seen as a result of the dialogue between the Swedish and German cultures, inscribed
in the history of medical thought of the epoch and pathological literary criticism.
Leonhard argued that Strindberg was wrongly treated as a schizophrenic but suffered
in fact from cycloid psychosis. The methodical approach, which Leonhard employed
to prove his point, is partly based on the tradition of literary anthropology and is close
to the traditions of the Russian humanistic psychiatry. Although Leonhard’s work was a subject to criticism, he shows interesting insights with current relevance. Invocating
Strindberg’s haunting works Days of Loneliness, Hell or Occult Diary, the authors of
the present article reproduce the symptom complex of the psychotic, emphasize
the importance of Leonhard’s complex and elaborate work, and draw attention to
Strindberg’s narrative style from the point of view of mental disorders and psychology.
In conclusion, the authors of the article announce the publication of the full text of
Leonhard’s essay in Russian translation, with literary and medical commentaries
A “História Natural de Portugal” de Leonhard Thurneysser zum Thurn, ca. 1555-1556
No full textThe existence of a German manuscript by Leonhard Thurneysser from Basel, started in 1555 “in the house of the noble lord and Lusitanian knight Master Damiani de Goes”, had fallen into the oblivion of historians for several decades. It contains reports on a number of plants and animals observed by the author during his stay in Portugal.
Another very curious aspect is his description of the black Africans he met in Lisbon. In spite of the text being written in early-modern high German, most of the names of the vegetal or animal species are mentioned in Portuguese. A project for a complete transcription of the extensive text is in progress
Kriegsheimkehr und Anerkennung in Leonhard Franks Erzählung Karl undAnna (1926)
No full textThe returning soldier has become a paradigmatic figure in 20th century literature, following the real mass phenomenon of the First World War. In this regard, many texts of the 1920s adopt classic motifs and patterns such as references to Homer's "Odyssey" or to the story of Martin Guerre—for instance "Karl and Anna" (1926), a novella by German author Leonhard Frank (1882–1961). Here, after his arrival from Russian war captivity, the veteran Karl grabs the spot of his fellow soldier Richard. With Richard's wife Anna he 'continues' a relationship as 'Richard.' Frank's novella, turned into several movies, is a tale of mistaken identities and betrayal and broaches the issue of recognition with regard to the returning soldier and his love relationship
Investigating Substitutional Point Defects in Nickel-Rich Layered Oxides through Ion Exchange Synthesis
No full textThe primary aim of this doctoral project was to comprehensively understand the capacity loss in the initial charge/discharge cycle of layered LiNiO2 (LNO) and related LiNiaCobMncO2 (NCM) cathode materials and to untangle the specific influences of material characteristics, such as particle size, composition and defect density. The project led to an innovative method of synthesizing LNO and Ni-rich NCM, diverging from the commonly used solid-state synthesis. This method produces layered oxides devoid of Ni_Li^• substitutional defects by creating sodium analogs of LNO and Ni-rich NCM, namely NaNiO2 and NaNiaCobMncO2. The larger size of sodium ions, compared to lithium ions, facilitates the formation of perfectly layered phases in these sodium analogs. Subsequently, such phases can be transformed into well layered LNO and NCM through an exchange of sodium ions with lithium ions. This approach enabled the examination of perfectly layered LNO and Ni-rich NCM for the first time.
Three sets of monolithic LNO particles with differing grain sizes were synthesized using the developed ion exchange method, allowing the selective study of the impact of particle size on the initial capacity loss without contributions from Ni_Li^• defects. The study reconstructed the influence of Ni_Li^• substitutional defects on conventional LNO and validated the findings by introducing magnesium to the lithium site using a unique dual ion exchange approach. The absence of Ni_Li^• defects led to faster lithium diffusion, but resulted in material degradation at high potentials, thus highlighting the ambivalent role of Ni_Li^• substitutional defects, which contribute to stabilization at high states of charge, but also hinder diffusion. Additionally, the role of nickel content in the initial capacity loss was studied on ion-exchanged NCM materials with variable nickel content. Similar to the effects observed for Ni_Li^• defects, the study revealed a complex interplay between stability (thermodynamics) and diffusion (kinetics). Lower nickel contents were found to stabilize the material at high potentials, whereas higher nickel contents mitigated polarization during discharge.
Throughout the investigation, a trade-off between material stability and lithium diffusion was observed. Materials with enhanced diffusion tended to be less stable and vice versa. The significant instability of LNO, even at low cut-off potentials of 4.3 V vs. Li+/Li, was observed in ion-exchanged materials for the first time. Literature known material was inherently stabilized due to the presence of Ni_Li^•, which obscured this property. This raises the question what the optimal concentration and the ideal properties of lithium ion substituents are.Other third-party funder
