Der Band ist so etwas wie ein Reisebuch – eine Empfehlung zum Spazierengehen. Er durchstreift Pirna und sein Umland. Wir begeben uns auf die Spuren einer vergessenen Familie: der Familie Scooler. Außerdem besuchen wir Orte der Zwangsarbeit, der Verfolgung von politischen Gegner*innen, der Bücherverbrennung und der »Euthanasie« im Nationalsozialismus. Die Shoah, die Verfolgung und Ermordung der europäischen Jüdinnen und Juden, und das Erinnern an sie ist nicht Teil unseres Alltags. Zu wenig bekannt und gekennzeichnet ist diese Geschichte. Wer hat hier gelebt und gewirkt, wer war Teil der Nachbarschaft? Wer musste gehen, wurde verfolgt und ermordet? Wessen Spuren suchen wir auf diesem Spaziergang? Redaktionsschluss: 31. März 2021

This dissertation attempts to elucidate early Isma`ili thought on various aspects of prophecy during the 4th A.H./10th C.E. century in the light of Kitab al-Is&dotbelow;lah&dotbelow; (Book of Correction) by Abu H&dotbelow;atim al-Razi (d. ca. 322/934--5), one of the leading da`is (missionaries) in the Iran of his day. Al-Is&dotbelow;lah&dotbelow; is on one level an early example of Neoplatonist influence on Isma`ili thought, taking the form of a polemic aimed at his coreligionist, Muh&dotbelow;ammad al-Nasafi. However, al-Is&dotbelow;lah&dotbelow; also shows a new doctrinal formulation of early Isma`ili discourse on prophetology, especially concerning the messianic figure of the Qa'im. / In al-Is&dotbelow;lah&dotbelow; al-Razi discusses the missions of each of the enunciator-prophets (nut&dotbelow;aqa' ) using the terminology of Greek-Hellenistic sciences, thereby implying that the Qa'im possesses a rank higher than any other prophet. In addition, whereas he appears to assign the Qa'im's political role to the leaders of the Isma`ili community in the present age, al-Razi describes a new era to be inaugurated by the figure, constituting a purified version of this world. In this way the figure of the Qa'im is depoliticized and spiritualized. It is thus suggested that al-Razi's thought on prophecy in al-Is&dotbelow;lah&dotbelow;, while theorizing the place of the Qa'im in sacred history, represents a response to the crisis in his own time engendered by the postponement of the Qa'im's final advent and victory.

The struggle for power between the military class and state officials in the 'Abbasï court on governmental affairs had assumed serious proportions by the time of Munis' rise to power (296/908). There was a similar struggle among the ghilman, the class to which Munis belonged. From the start, those ghilman particularly the Hujariya and the Masaffiva appeared as armed political groups rather than apolitical military units. The purpose of this thesis is to deal with Munis' political and military career at the 'Abbasi court between 296-321/908-933. Three focal areas were chosen for this study. (1) The struggle for power between the military class and the kuttab as exemplified by Munis' struggle with the wazir Ibn al-Furat. (2) The struggle for power within the military class itself as it appears through Munis' struggle with Harun b. Gharib and Yaqut. (3) The struggle between the military class and the khalifa as shown hy Munis' conflict with al-Muqtadir and al-Qahir.

There has been a considerable effort in the last years to decrease the amount of volatile organic compounds (VOCs) present in organic coatings. The risks to human health and environmental hazards associated with VOCs, governmental directives, and economic factors are the main driving forces behind this effort. One way of achieving less or no VOC containing coating systems is to produce low viscosity resins. Hyperbranched resins owing to their globular structure have low viscosities and are promising materials for decreasing the VOCs. In this research hyperbranched resins having properties close to alkyds were synthesized. Dipentaerythritol, which was used as the core was esterified with dimethylol propionic acid. The hyperbranched polyester was then esterified with the castor oil fatty acids (Castor FA). The hydroxyl group of the ricinoleic acid present in the castor FA was modified with different amounts of linseed oil fatty acids (Linseed FA) and benzoic acid. The chemical characterization of the resins was achieved by FTIR spectroscopy and the thermal properties were determined by DSC. Then, the physical and the mechanical tests were carried out. The resins containing the Castor FA only and 32.5 % Linseed FA in addition to the Castor FA had 24 and 68 Persoz hardness, respectively. The viscosity of the resins decreased from 17.3 Pa&amp / #61655 / s to 5.8 Pa&amp / #61655 / s as the amount of the Linseed FA was increased. The resins showed excellent adhesion, gloss, flexibility and formability.

In this research hyperbranched resins containing fatty acid residues like alkyds were synthesized. Dipentaerythritol which has six hydroxyl groups was used as the core molecule, and it was transesterified with (i) castor oil, and (ii) a mixture of castor oil and linseed oil at 240&deg / C in the presence of sodium hydroxide as catalyst. The resulting molecule, in either case, was then esterified with dimethylol propionic acid at 140&deg / C in the presence of p-toluene sulfonic acid as catalyst. Melamine-formaldehyde resin was synthesized to be used with the synthesized hyperbranched resins, and it was successfully modified by all hyperbranched resins at a ratio of 3:1. FTIR spectroscopy was used to characterize the hyperbranched resins and the thermal properties were determined by DSC. DSC showed that the hyperbranched resins decomposed between 315-345&deg / C. The viscosity of the resin that was synthesized by using only castor oil was 3.0 Pa.s and by using 50% linseed oil it was 1.0 Pa.s. When reacted with dimethylol propionic acid, the former&rsquo / s viscosity increased to 7.0 Pa.s, and the second&rsquo / s viscosity increased to 3.7 Pa.s. The hyperbranched resins showed excellent adhesion, gloss, flexibility, and formability. The mixture of hyperbranched resin plus melamine-formaldehyde resin samples had higher hardness values but lower gloss, adhesion and bending resistance values than the hyperbranched resins, and they had good impact and abrasion resistances.
