This is very much the case for Athens, one of the oldest cities in the world. Utilizing a large number of sources, we review such aspects of the city through the millennia of its history. Based on this, a case is presented, regarding a remarkable continuity of the city’s cultural expression, through the character of its urban environment.

Αυτό, όμως, που λείπει από την ελληνική, αλλά και την παγκόσμια βιβλιογραφία, είναι μία εξέταση του ζητήματος λαμβάνοντας υπόψη τη σχετική διεθνή ιστορική εμπειρία. Στην παρούσα εργασία γίνεται μία μελέτη συγκρίσεων που θα μπορούσαν να γίνουν με άλλες αντίστοιχες καταστάσεις, περιλαμβανομένων και άλλων «Μακεδονικών» που έχουν ή θα μπορούσαν να έχουν υπάρξει σε άλλα σημεία του κόσμου, και μία εξέταση του πώς είδε το θέμα η διεθνής κοινότητα. Στόχος, μία όσο γίνεται πιο αντικειμενική θεώρηση του προβλήματος και των λύσεων που προτάθηκαν, καθώς και αυτών που τελικά συμφωνήθηκαν.

The aim of this work is dual: to provide a well documented research on the evolution of the main Greek national symbol utilizing as many primary sources as possible, while identifying possibly or outright inaccurate elements that have been extensively reproduced.

In an effort to cover the most characteristic sectors of vehicle and “mechanical products” manufacturing in the country since 1800, an archive collected over a period of over three decades, is utilized in this work. Individual manufacturers and their products are presented, grouped into selected categories, in a concise manner and with the aim to provide an informative, easy reference material.

We present here a review of both theoretical and experimental studies of fluid flow through porous media, including fiber beds. For the practical porosity range of interest in continuous fiber composites processing (0.3< ϵ < 0.6), the permeability cannot be accurately described using the Blake-Kozeny-Carman equation, even though the flow is Newtonian at very low Reynold's number. For aligned fiber situations, the Kozeny constant, k, deviates radically from theory, depends on bed nonuniformities, and is only constant over very narrow porosity ranges. Thus, one cannot experimentally determine k at high porosities and use this value to describe low porosity situations. Theoretical attempts, based on perfectly spaced and aligned arrays of cylinders, adequately describe the transverse permeability of ideal fiber beds in the high porosity range, but do not succeed at porosities below 0.6. For axial flow through aligned fiber beds, the theory yields permeabilities much lower than are experimentally observed throughout the entire porosity range. For randomly arranged fibers, random cylinder theory also predicts permeabilities that are significantly lower than are measured.

Based on our conclusions in a recent review of pertinent literature (see Part I, this issue), Newtonian flow through ideal cylinder arrangements has been analyzed and measured. The analytical and numerical solutions agreed well with both our own experimental observation and those of others. Experiments with actual carbon fiber beds revealed significant deviations from ideal bed behavior. These deviations include dependence of the permeability on the nature of the permeant and the applied pressure difference, both of which make questionable the use of the Blake-Kozeny-Carman (BKC) equation to describe flow in real carbon fiber beds. Experiments that simulate the autoclave process by featuring combined permeation and consolidation of fiber beds have yielded additional dependencies of the permeability on process characteristics, such as the consolidation load and the original resin-rich areas within the fiber beds.

The experimental verification of the model is carried out by a viscometric study of the ternary system polymer A/polymer B/solvent. More precisely the viscometric study permits the determination of the critical concentration c** corresponding to the incipient overlap of spherical coils.
