State and Church in Byzantium during the Civil War of 1321-1328: the Emperor Andronikos II Palaiologos and the Patriarchs Gerasimos I and Esaias
No full textThe goal of the present research work is to determine the role of church in political events during the war between Andronikos II and Andronikos III Palaiologoi (1321-1328) in the Byzantine empire. Its urgency is defined by incomplete explanation of this aspect in Russian and foreign historiography. The first part of the article is devoted to the study of relations between the state and the church during the Andronikos II Palaiologos’ earlier rule (1282-1320). The author concludes that under the church troubles patriarchs sought to rely on the ruling emperor but happened to have no support. As far as state-church relations during the civil war are concerned, they are studied in the second part of the research work. The author puts an emphasis on the patriarchs Gerasimos I (1320-1321) and Esaias’ (1323-1334) political position and clears up the degree of their participation in the conflict between the emperors. He finds out that the church role in political events at that time was high enough. The crisis of power led to a change in relations between patriarchs and Andronikos II; in other words, during the civil war period they did not support him and came down on the side of his grandson. At the same time the synod remained loyal to the ruling emperor
Can governments do it better? Merger mania and hospital outcomes in the English NHS
No full textThe literature on mergers between private hospitals suggests that such mergers often produce little benefit. Despite this, the UK government has pursued an active policy of hospital mergers, arguing that such consolidations will bring improvements for patients. We examine whether this promise is met. We exploit the fact that between 1997 and 2006 in England around half the short term general hospitals were involved in a merger, but that politics means that selection for a merger may be random with respect to future performance. We examine the impact of mergers on a large set of outcomes including financial performance, productivity, waiting times and clinical quality and find little evidence that mergers achieved gains other than a reduction in activity. Given that mergers reduce the scope for competition between hospitals the findings suggest that further merger activity may not be the appropriate way of dealing with poorly performing hospitals.Hospital mergers, event study, quality, political influence.
Empowering People with a User-Friendly Wearable Platform for Unobtrusive Monitoring of Vital Physiological Parameters
No full textElderly people feel vulnerable especially after they are dismissed from health care facilities and return home. The purpose of this work was to alleviate this sense of vulnerability and empower these people by giving them the opportunity to unobtrusively record their vital physiological parameters. Bearing in mind all the parameters involved, we developed a user-friendly wrist-wearable device combined with a web-based application, to adequately address this need. The proposed compilation obtains the photoplethysmogram (PPG) from the subject’s wrist and simultaneously extracts, in real time, the physiological parameters of heart rate (HR), blood oxygen saturation (SpO(2)) and respiratory rate (RR), based on algorithms embedded on the wearable device. The described process is conducted solely within the device, favoring the optimal use of the available resources. The aggregated data are transmitted via Wi-Fi to a cloud environment and stored in a database. A corresponding web-based application serves as a visualization and analytics tool, allowing the individuals to catch a glimpse of their physiological parameters on a screen and share their digital information with health professionals who can perform further processing and obtain valuable health information
DC-DC Converters for Photovoltaic Powered DC Microgrid
No full textThe modern world demands more and more electric energy. At the same time, almost a billion more people are expected to gain access to electricity over the next decade. All of the above compose a very challenging future, where a continuously increasing amount of electric energy will be needed. However, the planet is not able to provide us anymore with the necessary resources for that, jeopardizing the environmental stability. The aim of this thesis is the design and testing of power electronics converters that will contribute positively to the production and distribution of sustainable energy. In particular, a Maximum Power Point Tracking Converter is designed and tested. The 6.4kW converter is able to connect to two separate PV strings. The output of the converter is connected to a bipolar DC distribution grid. Afterwards, a 3.68kW Voltage Balancing Converter was designed for the stabilization of the voltage between the two phases of a bipolar DC grid. Particular interest is given to the challenges that arouse for the power supply of a DC Micro-Grid from a Photo-Voltaic plant. The project took place in the DC lab of the company DC Opportunities.Electrical Engineering | Sustainable Energy Technolog
Photoelectrode design principles for efficient photo-charging of solar redox flow batteries
No full textIn connection with attempts to increase the Solar Redox Flow Battery (SRFB) viability, an investigation was done into the charge carrier transport mechanisms entailed at the photoelectrode interlayer interfaces. On the basis of a preliminary study, the investigation focused on the development of a suitable conducting layer at the electrolyte/electrode interface as well as the development and control of a hole extraction layer, based on the device electronic structure and energy levels matching. Research was conducted into the properties of various prospective materials that could improve charge carrier transport at the electrolyte/photoelectrode interface. Once the optimal configuration is determined, the photoelectrode and redox couples are prepared and characterized and the photocharging performance of the device is optimized. Furthermore, the control of the formation conditions of a hole extraction layer took place, in order to yield improved internal charge carrier separation and transport. Various hole transport layers were assessed in SRFB system in relation to the photo-charging performance. The described process resulted in the development of a conducting layer through the growth of well distributed islands, which led to a high solar-to-chemical conversion of 9.4%. Through the control of the formation conditions of the hole extraction layer, better spatial separation of the photogenerated charge carriers was achieved, leading to improved device performance. Despite the enhanced viability of each device in terms of efficiency, further research into the long-term stability is essential for its practical implementation. This mainly relates to electrolyte degradation to form solid precipitates and photocorrosion of the absorber semiconductor materials in acidic conditions.Electrical Engineering | Sustainable Energy Technolog
Canoni «giambici» d’epoca bizantina e postbizantina. Un’‘isola’ nella produzione innografica della chiesa greca
No full textIn the first part of the paper, the author analyses the Sicilian reception of the rare innographical genre in classical style represented by the canons in Byzantine dodecasyllables, which were composed particularly by Theophanes (of Sicily?), Methodios of Syracuse, Eugenios of Palermo; instead, the second part is dedicated to the isolated, but interesting, production of «iambic» canons in post-Byzantine era at the hands of Manuel Korinthios, Nicholas Mavrocordatos, George Chrysogonos Trapezountios, Gerasimos Ioannoulis, John Hierosolymos, Antonio Rocchi
Unravelling the practical solar charging performance limits of redox flow batteries based on a single photon device system
No full textIn recent years, solar redox flow batteries have attracted attention as a possible integrated technology for simultaneous conversion and storage of solar energy. Unlike solar water splitting technologies which require at least 1.8V for meaningful performance, a lesson learned from previous solar redox flow battery (SRFB) studies is that even single-photon-devices can demonstrate unbiased photo-charging owing to the flexibility of redox couple selection. Thus, in this paper, we present the theoretical model reflecting experimental parameters, such that we can highlight important parameters that merit the most attention in further studies towards the practical development of SRFBs. Importantly, the results clearly show how to choose the optimum combination of semiconductor and redox couples under unavoidable limitations that a practical system would encounter, including, but not limited to optical loss by the electrolyte, overpotential, device architecture and chemical potentials.Accepted Author ManuscriptChemE/Materials for Energy Conversion and Storag
