Background Degenerative changes of the cervical spinal column are the most common cause of spinal cord lesions in the elderly. Conventional clinical, electrophysiological and radiological diagnostics of spinal cord compression are often inconsistent. Materials and methods The feasibility and diagnostic potential of a novel T1 mapping method at 0.5 mm resolution and 4 s acquisition time was evaluated in 14 patients with degenerative cervical spinal canal stenosis (SCS) and 6 healthy controls. T1 mapping was performed in axial sections of the stenosis as well as above and below. All subjects received standard T2-weighted MRI of the cervical spine (including SCS-grading 0-III), electrophysiological and clinical examinations. Results Patients revealed significantly decreased T1 relaxation times of the compressed spinal cord within the SCS (912 ± 53 ms, mean ± standard deviation) in comparison to unaffected segments above (1027 ± 39 ms, p, Highlights • Rapid T1 mapping at 0.5 mm resolution was tested in cervical spinal canal stenosis (SCS). • T1 relaxation times significantly decreased within the SCS. • T1 relaxation times were significantly lower in grade II vs grade I SCS. • Central conduction deficits were inversely correlated with T1 relaxation time. • Rapid T1 mapping robustly and accurately quantifies spinal cord compression.

Wissenschaftlicher Bericht - FZKA 6035 Thermomechanische Versuche mit dem First Wall Mock-up TS1 Ein Ausschnitt (Mock-up) der Ersten Wand vom Design für den Next European Torus (NET) stand als wasser-gekühlte Stahl-Struktur für Experimente zur Verfügung. Weil der Mock-up Vorschädigungen durch eine große Zahl von Thermoelement-Bohrungen aufwies, war er nicht für thermische Ermüdungsexperimente vorgesehen; vielmehr wurde er als prototypische Hintergrundstruktur verwendet für thermomechanische Tests mit Schutzziegeln auf Graphit-Basis und deren Haltevorrichtungen. In einer ersten Testreihe wurde die Oberfläche des ungeschützten Mock-ups einer thermischen Last ausgesetzt. Die Vorhersage einer FE Modellrechnung konnte mit Dehnungen, die auf seiner Rückseite gemessen wurden, in vernünftigem Umfang bestätigt werden. In einer zweiten Testreihe wurde der Mock-up mit einem strahlungs-gekühlten Ziegel, der nicht in engem thermischen Kontakt mit dem Mock-up stand, geschützt. Die Tests zeigten, daß es sehr wichtig ist, auf angemessen dimensionierte Spalte zu achten, die Unterschiede in der thermischen Ausdehnung und Verbiegung auch während der thermischen Transienten zulassen. Schließlich wurde der Mock-up mit leitungs-gekühlten Ziegeln, die mit einer Zwischenschicht aus flexiblem Graphit auf den Mock-up gedrückt wurden, geschützt. Die Testergebnisse zeigten, daß der Wärmeübergang an der Kontaktschicht gleichmäßig war und auch nach thermischen Zyklen auf hohem Temperatur-Niveau zuverlässig erhalten blieb.

Six virus laboratories from various parts of the German Federal Republic and West Berlin undertook investigations into polio-myelitis immunity in 1972. A total of 267 persons aged up to 20 years were investigated for neutralizing antibodies against the three types of polio virus. The study showed that from the fourth year of life approximately 70% of the persons investigated had antibodies against all three types of polio virus. In some younger children the equivalent values were considerably lower. After the fourth year of life there were only slight differences in the humoral immunity against the three polio virus types. There was no evidence that the immunity level had deteriorated up to the 20th year of life and thus there is no indication of the necessity for a repeat immunisation at a certain time. The investigation confirmed that three oral administrations of trivalent vaccine, as are now generally recommended as basic immunization in the German Federal Republic, result in a conversion rate of over 90% against each of the three virus types.

The chapter presents an epistemological reading of working with life histories in the education of adults. The narration of one's own history can transform into a journey of self-knowledge and self-inquiry, but only if a critical examination of personal, institutional and social presuppositions and determinants is fostered. This requires the presence of the "other" as a constraint and potential revelation of one's own otherness.

Toma como base teórica os Estudos Feministas nas interfaces com a produção do campo da Educação de Jovens e adultas/os e do Trabalho e Educação e metodologicamente, nos apropriamos dos aportes da pesquisa qualitativa e da história oral, com o enfoque nas histórias de vida. Como ferramentas, utilizamos do grupo de discussão e das entrevistas com 10 educandas. Os resultados apontaram que elas enfrentam problemas de ordem socioeconômica e aqueles advindos das relações de gênero, como também, dificuldades para acompanhar as demandas da escola. As dificuldades de aprendizagem são explicitadas pelo longo período fora da escola; pela persistência de uma cultura escolar e de práticas pedagógicas que não levam em consideração as especificidades das/os sujeitas/os da EJA. Os obstáculos decorrentes também das relações sociais de gênero impactam seus processos de escolarização. A persistência da desigualdade sexista no âmbito privado reflete no espaço educacional, na medida em que esses obstáculos permeiam a inserção, a permanência e o êxito escolar delas; o que incide também na sua inserção no mercado de trabalho, levando-as a desempenharem atividades similares àquelas que já realizam no espaço reprodutivo e que perpetuam a divisão sexual do trabalho. As funções exercidas na conjugalidade e na maternidade, acrescida da existência de discriminação desse segmento estudantil, no espaço escolar, indicaram que os seus processos formativos, decorrem mais de sua força de vontade, resistência e autodeterminação, que das condições objetivas da Instituição, mesmo considerando as ações políticas de vigília e de resistência do Colegiado do Proeja. Em face dos resultados apontados, e apesar das interdições sofridas nos seus percursos de vida, defendemos que as ofertas dos dois Programas, na perspectiva da interseccionalidade, contribuem para o empoderamento e para a emancipação das mulheres.
