Healthcare services are increasingly confronted with challenges related to old age mental disorders. The survey aimed to provide an overview of existing psychogeriatric services in Albania, Bulgaria, Greece, and North Macedonia.
Methods
After identification of psychogeriatric units across the four countries, their head physicians were asked to provide data on their clinical, teaching, and research activity, as well as staff composition. Moreover, the attitudes of head physicians to current needs and future service development were explored.
Results
A total of 15 psychogeriatric units were identified (3 in Bulgaria, 8 in Greece, and 4 in North Macedonia). Results show wide variation regarding the location, team size and composition, service availability, numbers of patients attending, and inpatient treatment length. Most head physicians underscored the urgent need for breakthroughs in the graduate and postgraduate education in psychogeriatrics of medical and nonmedical professionals, as well as in the interconnection of their units with community primary healthcare services and long-term care facilities for seniors via telemedicine. They would welcome the development of national standards for psychogeriatric units, potentially embodying clear pointers for action. A number of head physicians advocated the development of nationwide old age mental health registries.
Conclusions
Regional disparities in resources and services for seniors’ mental health services were unveiled. These data may enrich the dialogue on optimizing psychogeriatric services through planning future cross-border collaborations mainly based on telemedicine services, especially in the era of the novel coronavirus pandemic, and training/education in psychogeriatrics of mental health professionals.
Cathars have long been regarded as posing the most organised challenge to orthodox Catholicism in the medieval West, even as a "counter-Church" to orthodoxy in southern France and northern Italy. Their beliefs, understood to be inspired by Balkan dualism, are often seen as the most radical among medieval heresies. However, recent work has fiercely challenged this paradigm, arguing instead that "Catharism" was a construct of its persecutors, mis-named and mis-represented by generations of subsequent scholarship, and its supposedly radical views were a fantastical projection of the fears of orthodox commentators. This volume brings together a wide range of views from some of the most distinguished international scholars in the field, in order to address the debate directly while also opening up new areas for research. Focussing on dualism and anti-materialist beliefs in southern France, Italy and the Balkans, it considers a number of crucial issues. These include: what constitutes popular belief; how (and to what extent) societies of the past were based on the persecution of dissidents; and whether heresy can be seen as an invention of orthodoxy. At the same time, the essays shed new light on some key aspects of the political, cultural, religious and economic relationships between the Balkans and more western regions of Europe in the Middle Ages.

Results from UBVRI photometric observations of the pre-main sequence star GM Cep obtained in the period 2011 April–2014 August are reported in the paper. Presented data are a continuation of our photometric monitoring of the star started in 2008. GM Cep is located in the field of the young open cluster Trumpler 37 and over the past years it has been an object of intense photometric and spectral studies. The star shows a strong photometric variability interpreted as a possible outburst from EXor type in previous studies. Our photometric data for a period of over six years show a large amplitude variability (ΔV ~ 2.3 mag) and several deep minimums in brightness are observed. The analysis of the collected multicolour photometric data show the typical of UX Ori variables a colour reversal during the minimums in brightness. The observed decreases in brightness have a different shape, and evidences of periodicity are not detected. At the same time, high amplitude rapid variations in brightness typical for the classical T Tauri stars also present on the light curve of GM Cep. The spectrum of GM Cep shows the typical of classical T Tauri stars wide Hα emission line and absorption lines of some metals. We calculate the outer radius of the Hα emitting region as 10.4 ± 0.5 R⊙ and the accretion rate as 1.8 × 10− 7 M⊙ yr− 1.
Low-cost and chemical resistant microfluidic devices based on thermoplastic elastomers have been fabricated by hot embossing technology. Commercial available thermoplastic elastomer foils based on polyurethane (PU) in a thickness range of 100-600 μm have been used. Prior to the fabrication of the microfluidic devices the chemical resistance of the material against a wide range of standard biological buffer solutions and solvents had been analysed. We created systems of channels, reservoirs and holes for the connections to external capillaries by double-sided hot embossing with an alignment accuracy of +/- 3 micrometer. Closed channel structures were produced by an additional chemical bonding process of the embossed devices with another thermoplastic elastomer foil. The total volume of the fluidic cell was 2 μl/sensor for the use with SAW (surface-acoustic wave) sensor chip and about 0.2 μ/sensor for the impedance sensors. A novel multi-chamber fluidic device was successfully tested for in-situ immobilization of thrombin antibodies and Bovin Serum Albumin (BSA) on different sensor elements of the same sensor chip.
Wsi2 films were prepared by rapid thermal annealing (RTA) in the temperature range of 800 -1400 °C for time durations of 15 sec -3 minutes. In some of the treatment experiments different gases were involved and a conclusion is made about the role of hydrogen favoring Wsi crystal phase growing at 800 °C. W films with thichnesses in the range 200 Å - 1000 Å were deposited on monocrystalline Si by pyrolitical decomposition of W(CO)6 in CVD reactor at atmospheric pressure and argon atmosphere. Reflection High Energy Electron Diffraction (RHEED) and Scanning Electron Microscopy (SEM) technics were used for structural characterization and FPP-100 device for resistance measurements. Results show that by solid state reaction applied at different RTA processes WSi2 phase could be formed.Resistivities as low as 2-3 mΩ.cm are obtained for 800 -1000 °C.
Tungsten and molybdenum hexacarbonyls were used as precursors in chemical vapour deposition process for preparation of W and Mo thin films. Pyrolitical decomposition of these precursors proceeds at temperatures of 250–400°C. Thin films with thicknesses in the range of 0,02–1 μm were deposited on different substrates - bare or covered with CdTe glass, and monocrystalline Si. Microstructural studies performed by Reflection High Energy Electron Diffraction (RHEED) method showed that films deposited tend to grow textured. This is discussed as probably due to differences in the growth rate for various crystal planes. The sheet resistances of the as-deposited W and Mo films are in the range of 20–30 Ω/□ for thicknesses of 0.15 μm. After thermal annealing the resistance of W films drops to about 2 Ω/□ and for Mo films to about 9Ω/□. Decreasing in the resistivity of the films is tightly connected with the decreasing in the impurities concentration. These impurities are considered to be in the base of the observed behaviour of the temperature dependence of the electrical resistance of the films. The CVD-W and Mo films are studied as back contacts on CdTe layer in CdS/CdTe photocells. In the paper some preliminary results are presented for the sheet and contact resistances when CVD W and Mo films are deposited at lower temperatures on the surface of CdTe layers, deposited by closespaced sublimation method. The thin film materials, produced by CVD technology look promising with respect to the required high deposition rates and extremely wide deposition areas in the mass production of solar cells.
