Dimitrios Tsamis Karatasos : a symbol of Greek, Serbian and Bulgarian friendship
Full text linkTwo Serbian texts extol the contribution of Dimitrios Tsamis Karatasos to the Balkan joint effort to throw off the Ottoman yoke. These texts are analysed by the author within the historical framework of their period, so that the man’s personality and work may be accurately evaluated from a fresh viewpoint. More specifically, the author conducts a research on the tombstone of Dimitrios Tsamis Karatasos, which he discovered himself at Naoussa, and the octet engraved on it, which is also published here. The work is illustrated by seven plates, of which four have not been published previously

Factors determining the occurrence and characteristics of new particle formation events - A study over a continent
Full text linkNew Particle Formation (NPF) events, an important source of ultrafine particles in the atmosphere, were studied in multiple sites across Europe. Apart from the importance of meteorological conditions and atmospheric composition variables and compounds, such as the solar radiation intensity, the relative humidity or the condensation sink in the occurrence and development of the events, the importance of the origin of the incoming air masses and the specific characteristics that come with them is underlined. The increased formation rate of particles of 10 nm diameter calculated in the present study (being at a greater size than that of the initial particle formation occurring at about 1.5 nm and thus affected as a metric by the growth of the particles) and growth rates observed within the urban environment are associated with the increased presence of condensable species found in such environments, regardless of the geographical location within the European continent.
The NPF process is also studied according to the different aspects that define it, the frequency of the events, the formation and growth rates of the particles, and the specific role of each one of the atmospheric variables was calculated throughout Europe using the large dataset available, providing an insight of the effect of these variables on the NPF mechanisms. Finally, the range of the effect of these events on the ultrafine particle composition in each area was studied and the importance of the events in the air quality of a given area is displayed

NPF UK Data
No full textNew Particle Formation (NPF) events have different patterns of development depending on the conditions of the area in which they occur. In this study, NPF events occurring at three sites of differing characteristics (rural Harwell (HAR), urban background North Kensington (NK), urban roadside Marylebone Road (MR), London, UK) were studied (seven years of data). The different atmospheric conditions in each study area not only have an effect on the frequency of the events, but also affect their development. The frequency of NPF events is similar at the rural and urban background locations (about 7% of days), with a high proportion of events occurring at both sites on the same day (45%). The frequency of NPF events at the urban roadside site is slightly less (6% of days), and higher particle growth rates (average 5.5 nm h-1 at MR compared to 3.4 nm h-1 and 4.2 nm h-1 at HAR and NK respectively) must result from rapid gas to particle conversion of traffic-generated pollutants. A general pattern is found in which the condensation sink increases with the degree of pollution of the site, but this is counteracted by increased particle growth rates at the more polluted location. A key finding of this study is that the role of the urban environment leads to an increment of 20% in N16-20nm in the urban background compared to that of the rural area in NPF events occurring at both sites. The relationship of the origin of incoming air masses is also considered and an association of regional events with cleaner air masses is found. Due to lower availability of condensable species, NPF events that are associated with cleaner atmospheric conditions have lower growth rates of the newly formed particles. The decisive effect of the condensation sink in the development of NPF events and the survivability of the newly formed particles is underlined, and influences the overall contribution of NPF events to the number of ultrafine particles in an area. The other key factor identified by this study is the important role that urban pollution plays in new particle formation events

The Exemplary Life of Dimitrios Vikelas (1835-1908)
Full text linkThis paper describes the "satisfying curve" of Dimitrios Vikelas' life journey, starting from Syros in 1835, moving via Constantinople, Odessa, and Syros again, to London, Paris and finally Athens. It explores Vikelas' multiple aspects, as merchant, writer, traveller, lecturer and essayist, Olympic founder, educationalist, book collector and philanthropist, all of which were united in the public-spirited man of letters (logios). It sets Vikelas in the context of the Greek commercial diaspora, the world of the London expatriate Greek community, and the dynamic society of late nineteenth-century Athens, beginning in the 1870s to act as a magnet to Greek expatriates. The author stresses two qualities of Vikelas: his belief in the idea of a progressive Greek state marked by advances in education, culture, tourism and standards of public life; and the self-awareness and experience which inform his autobiographical writings, not only his memoir My Life but also his last such work, The War of 1897
