De plantarum polline
No full textCarl Julius von Fritzsche (1808-1871), Pharmazeut und Chemiker. Geb. Neustadt (Sachsen, D.) 29.10.1808, gest. Dresden 20.06.1871 (nach dem im Russischen Reich bis Februar 1918 verwendeten Julianischen Kalender eine Differenz von 12 Tagen: 17.10.1808 – 08.06.1871).- Fritzsche, Sohn des Arztes Christian Ferdinand Fritzsche, erhielt bis zu seinem 14. Lebensjahr Privatunterricht in Dresden, danach eine pharmazeutische Ausbildung bei seinem Onkel Friedrich Adolph Struve (1781-1840). 1830 wurde Fritzsche Assistent im Laboratorium des Chemikers Eilhard Mitscherlich (1794-1863) und immatrikulierte 1831 an der Philosophischen Fakultät der Universität Berlin. Hier promovierte er am 10. August 1833 mit seiner Schrift „De plantarum polline“ (Über den Pflanzenpollen; hier präsientiert) zum Dr. phil. Noch 1833 nahm Fritzsche das Angebot seines Onkels Struve an, in St. Petersburg die Leitung einer neu gegründeten Anstalt zur Herstellung künstlicher Mineralwässer zu übernehmen, und übersiedelte nach Russland. Am 24. August 1838 wählte ihn die Akademie der Wissenschaften in St. Petersburg zum Adjunkten für Chemie, was eine zusätzliche fixe Bezahlung und deutliche Reputation bedeutete. Am 06.04.1844 wurde Fritzsche überdies zum außerordentlichen, am 10.04.1852 dann sogar zum ordentlichen Akademiemitglied gewählt; 1870 verlieh man ihm den russischen erblichen Adel. 1869 erlitt Fritzsche einen Schlaganfall, von dem er sich nie wieder ganz erholte; 1870 reiste er nach Deutschland und starb 1871 im Kreis seiner Familie in Dresden. Von seinen 81 wissenschaftlichen Publikationen sind nur fünf botanischen Inhalts, die anderen behandeln rein chemische Themen. Die botanischen Publikationen sind: Beiträge zur Kenntniss des Pollens. Erstes Heft (Berlin 1832); Dissertatio de plantarum polline (Berlin 1833); Ueber den Pollen der Pflanzen und das Pollenin. In: Annalen der Physik und Chemie 108 (= 2. F., 32), 1834, S. 481-492; Ueber die Entwicklung des Pflanzeneies in seinen frühesten Zuständen und über die Bildung der Häute desselben. In: Archiv für Naturgeschichte 2, 1835, 229-232; Ueber den Pollen. In: Mémoirs de savants étrangers 3, 1837, S. 649-670.

Propaganda on Trial: the Cases against Julius Streicher and Hans Fritzsche
No full textThrough Article 25(3)(e) ICC Statute, the International Criminal Court has jurisdiction where there is “direct and public incitement to commit genocide”. However, this provision has not been applied by the court yet. In 1946, the International Military Tribunal for Nuremberg convicted Julius Streicher as the first person for the crime of incitement. Hans Fritzsche was also tried for incitement. He was acquitted. The question explored in this dissertation is what relevance these two cases have regarding the interpretation of Article 25(3)(e). The question is answered through analysing the international criminal law on the subject. The main focus will be the cases against Streicher and Fritzsche. However, other important considerations are the ICTR propaganda cases which took place within the last 10 years. Especially, the Prosecutor v Nahimana established a clear link to the IMT cases. The dissertation therefore examines such legal problems which were discussed by the IMT and the ICTR but are still not solved by the ICC Statute. The dissertation examines the normative status of incitement in the ICC Statute, the possibility of holding private propagandists liable under international law and the definition of the elements of the crime of incitement. These last points make it necessary to discuss the legal nature of incitement and its external and mental elements.
Other papers on the subject usually put the ICTR trials in the centre and use the IMT cases as a supporting argument. However, this dissertation answers the questions vice versa. Thus, the legal problems are explained in the context of the IMT cases and then answered through considering the IMT judgments and the development of the law. The dissertation argues that the cases against Streicher and Fritzsche are particularly relevant and laid the foundation for the subsequent development of the crime. The author considers this development as positive and argues in favour of the IMT judgments.
The dissertation illustrates that the IMT answered important questions several centuries before the ICTR and gives therefore the blueprint for the ICC. The ICC is not bound by their findings and it is still not possible to regard these specific legal answers of the IMT and ICTR as customary law. However, the ICC will have to find good arguments if it does not want to apply the jurisprudence, created by the IMT in its propaganda cases against Streicher and Fritzsche
Exchange bias effects in Fe nanoparticles embedded in an antiferromagnetic Cr2O3 matrix
No full textPowders consisting of ferromagnetic (FM) Fe nanoparticles, of about 7 nm in size, embedded in an antiferromagnetic (AFM) Cr2O3 matrix have been obtained by high-temperature reduction under a hydrogen atmosphere of a mixed Cr–Fe oxide. This FM–AFM system exhibits exchange bias effects, i.e. a loop shift (HE) and coercivity enhancement (ΔHC), when field-cooled through the N´eel temperature, TN, of Cr2O3. The exchange bias properties were measured as a function of temperature. HE and ΔHC are found to vanish at about TN(Cr2O3), indicating a good quality AFM matrix. Hence, high-temperature reduction of mixed oxides is demonstrated to be a suitable technique to develop new types of FM–AFM exchange-biased nanoparticles, from which novel applications of this phenomenon may be developed
Agile as a Vehicle for Values: A Value Sensitive Design Toolkit
No full textThe ethics of technology has primarily focused on what values are and how they can be embedded in technologies through design. In this context, some work has been done to show the efficacy of several design approaches. However, existing studies have not clearly pointed out the ways which design team managers can use design-for-values approaches to organise and use technologies in practice properly. This chapter attempts to fill this gap by discussing the value sensitive design (VSD) approach as a valuable means of co-designing technologies as a toolkit for existing workflow management, in this case, Agile. It will be demonstrated that VSD shows promise as a way of democratically designing technologies as well as fostering democratic technology policy innovation.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Ethics & Philosophy of Technolog
