Hydrodynamic Analysis

In this work, a novel Boundary Element Method (BEM) is developed and applied to the investigation of the performance of Oscillating Water Column (OWC) systems, taking into account the interaction of the incident wave field with the bottom topography. The modelling includes the effect of additional upwave walls and barriers used to modify the resonance characteristics of the device and improve its performance as the U-OWC configuration. Numerical results illustrating the effects of depth variation in conjunction with other parameters—such as chamber dimensions as well as the parameters associated with the turbine and power take-off system—on the device performance are presented and discussed. Finally, a case study is presented regarding the potential installation of an OWC in a selected port site in the Black Sea, characterized by a good wave energy potential, on the coast of Romania.

Primary Unit

The Black Sea region from 1768-1830s has traditionally been characterized as a theater of warfare and imperial competition. Indeed, during this period, the Ottoman and Russian empires engaged in four armed conflicts for supremacy in the Balkans, the Caucasus, and on the Black Sea itself. While not discounting geo-strategic and ideological confrontation between the Ottoman and Russian empires, this article - by adopting the Black Sea region as its primary unit of historical and political analysis - will emphasize the considerable amount of exchange that took place between the Ottoman and Russian empires in the Black Sea region in the late eighteenth and early nineteenth centuries. Building upon a case study of Bulgarian migration between the Ottoman and Russian empires and as part of a broader discussion on Ottoman-Russian Black Sea diplomacy this article will detail joint Ottoman-Russian initiatives to control their mutual Black Sea borderland.

AbstractIn an archaeometric research project supported by the Volkswagen Foundation (Project 90216 [https://earlynomads.wordpress.com/]), working groups consisting of chemists, geologists and archaeologists in Berlin, Kiev and Saint Petersburg collaborated on analysing pottery recovered from Late Bronze Age and Early Iron Age burials and settlements from sites of different archaeological cultures in the steppes and forest steppes north of the Black Sea. The article presents the results of the classification of 201 samples using energy-dispersive X-Ray fluorescence spectrometer (pXRF) compared to the results of MGR-analysis and WD-XRF of these samples. Fingerprints for the seven sites studied could be defined.
