This article analyses the relationship between Orthodoxy and state from the unification of the Principalities of Moldavia and Wallachia in 1859 to the creation of Greater Romania in 1918. Examining the attitudes of political leaders towards the dominant religion, this article argues that during the reigns of Prince Cuza and King Carol I the Church became a state institution closely connected to the development of political regimes. It is suggested that by claiming doctrinal religious connections with Constantinople and independence from foreign intervention in the Church’s affairs, religious and political leaders from 1859 to 1918 amplified the construction of Romanian national mythology which contributed towards the political unity of the state.

Für deutsche Migranten des 19. Jahrhunderts war Großbritannien eines der wichtigsten Zielländer innerhalb Europas. Zum ersten Mal wird eine der zahlreichen deutsch-ethnischen Kolonien einer mikrohistorischen Untersuchung unterzogen. Die Perspektive erlaubt quellengestützt genauere Aussagen zu Themenkomplexen wie Wanderungsverhalten, Berufsstruktur oder ethnischer Selbstorganisation. In Glasgow bildete sich ein dichtes Netz an ethnischen Vereinigungen, das sich nach Kriegsausbruch unter dem germanophoben Druck der britischen Öffentlichkeit sowie staatlichen Maßnahmen wie Internierung, Repatriierung oder Enteignung fast vollständig auflöste. Die Glasgower Fallstudie wird durch zahlreiche Querverweise auf andere Regionen und Länder in einen größeren migrationsgeschichtlichen Rahmen eingeordnet. German migrants of the 19th century. Century Britain was one of the main destination countries within Europe. One of the many German ethnic colonies of a micro historical investigation is subjected for the first time. The perspective allows more detailed statements on topics such as migratory behavior, occupational structure or ethnic self-organization source based. A dense network of ethnic associations that almost completely disbanded after war germanophoben pressure from the British public and Government measures such as detention, repatriation or expropriation was formed in Glasgow. The Glasgow case study are classified by numerous cross-references to other regions and countries within a larger migration history.

The available literature has been surveyed to determine the parameters affecting fuelling requirements of spark ignition engines and their relation to engine performance and emissions. Theories and experiment relating to two phase and multi-component flows have also been examined and the techniques employed in the measurement of droplet sizes and liquid wall films have been reviewed. Following preliminary steady flow visualisation experiments to examine the trajectories of droplets discharging from the valve port an extensive practical investigation of the spectrum of droplet sizes formed by the break up of the wall film has produced results which have been correlated in terms of the important fuel and airflow parameters. It is concluded that the Sauter mean diameter of droplets formed by the break up of the wall film will vary between 70 and 150 m, depending on the operating conditions of the engine. The spectra of droplet sizes measured show that a significant proportion of the total mass of the wall film breaks into drops which will be too large to burn completely and, by comparison with measurements of unburned hydrocarbon emissions from engines supplied with a homogeneous mixture of air and gaseous hydrocarbons, it is concluded that the droplets from the wall film are likely to increase emissions by 50%.

The Wilhelmine battle fleet was a powerful symbol of national strength and unity not only within the Reich but also in German ethnic communities abroad. A global network of 179 navy clubs with 9,500 members (1913) was coordinated by the Berlin-based Central League for German Navy Clubs Abroad (Hauptverband Deutscher Flottenvereine im Auslande). Its aims were the collection of migrants’ money for concrete navy projects and the promotion of allegiance to the Reich and of ethnic cohesion abroad. The article analyses German navy campaigning within a transnational framework and supports the view that migrants were discursively drawn into Imperial Germany’s global aspirations as outposts of ‘Germanness’ abroad. Existing scholarship, however, tends to look at them as passive objects of a discourse conducted within Germany, as a canvas onto which (semi-)colonial fantasies could be projected. This article argues, rather, that ‘Germans abroad’ could also be active participants within a transnationally conducted and multi-directional discourse. They did not necessarily defy nationalist assumptions but could, in fact, be deeply embedded in the construction of these assumptions.

German unification in 1871 not only changed the political, economic and geographical landscape of the country, it also had a significant impact on those Germans who found themselves living outside, or migrating across, the borders of the newly founded Empire. It also focuses on the activities of the Central League in Britain and its Empire. For comparative reasons, some areas outside the Empire also included. Within Britain, five local branches can be identified during the period 1898 to 1914: London, Birmingham, Newcastle, Glasgow, and Edinburgh-Leith. For London, membership numbers obtained, but judging by annual contributions this branch appears strongest in Britain. The article has shown that researching the activities of the Central League in Britain and its Empire can add valuable insights to the mechanics of transnational ethnic network creation, as well as to the nature of potentially frictional contact zones between German migrants and British colonial rule.

Electrical and thermal transport properties of the carbon nanotube bulk material compacted by spark plasma sintering have been investigated. The electrical conductivity of the as-prepared sample shows a lnT dependence from 4 to 50 K, after which the conductivity begins to increase approximately linearly with temperature. A magnetic field applied perpendicularly to the sample increases the electrical conductivity in the range of 0-8T at all testing temperatures, indicating that the sample possesses the two-dimensional weak localization at lower temperatures (?50 K), while behaviors like a semimetal at higher temperatures (?50 K). This material acts like a uniform compact consisting of randomly distributed two dimensional graphene layers. For the same material, the thermal conductivity is found to decrease almost linearly with decreasing temperature, similar to that of a single multi-walled carbon nanotube. Magnetic fields applied perpendicularly to the sample cause the thermal conductivity to decrease significantly, but the influence of the magnetic fields becomes weak when temperature increases.

The surfaces of bulk carbon nanotubes compacted by plasma spark sintering have been modified with polytetrofluorethylene, thereby producing a super-hydrophobic surface with a contact angle above 160°. The surface roughness and air trapped in pores and between the polytetrofluorethylene particles are responsible for the super-hydrophobility. The material can be machined into desired shapes with fine and complex channels, allowing internal surfaces to also be super-hydrophobic.

The United States was undoubtedly the most important, but by no means the only country of destination for German immigrant entrepreneurs. German industrialists, merchants, and other entrepreneurs could be found in virtually all world regions where international trade or local markets promised satisfactory returns. They were globally dispersed manifestations – and motors – of Germany’s expanding economy between unification in 1871 and the First World War.
