The provision of healthy modern housing for all was one of the foremost ideals of the Modern Movement, and inspired a vast wave of planning and building across the world during the 20th century. In the last quarter of the century, even as the foundational programmes of Europe and America lost their impetus, the baton was passed on to other countries, especially in eastern Asia, where the narrative of Modern mass housing was reinvigorated for the next century - a unique example of a key Modernist project that actually continues and thrives today, and which thus forms a principal focus of interest for DOCOMOMO – the leading international organisation promoting the documentation and conservation of buildings, sites and neighbourhoods of the Modern Movement.
As heritage, the built legacies of this diverse and multi-generational adventure are almost always too controversial to qualify for conservation strategies. Instead, therefore, recording and inventorisation must dominate the heritage interest in this field. In the recognition of that fact, DOCOMOMO’s International Specialist Committee on Urbanism and Landscape, in partnership with the Scottish Centre for Conservation Studies at the University of Edinburgh, has launched the International Mass Housing Archive, whose aim is to provide an open-access library of images of significant housing projects in each working-group territory, free of copyright restrictions. These files may be copied, edited and shared on condition the appropriate citation is used, as per the terms of the attached Creative Commons Attribution licence.
### Structure ###
The International Mass Housing Archive is subdivided under geographical headings corresponding to the constituent working groups of DOCOMOMO, and the individual housing projects are searchable under city and project name. Initially, the Image Archive will be managed and augmented centrally by DOCOMOMO and the SCCS, in partnership with University of Edinburgh Information Services, commencing with pilot city surveys sourced from our own photographic records in the first instance.
The archive is related to several existing mass housing documentation initiatives. These include two concerning Britain, ‘Tower Block UK’ and the online version of the 1994 book, Tower Block: http://www.towerblock.eca.ed.ac.uk/ and http://towerblock.org/TowerBlock.pdf; and one concerning Hong Kong: see http://www.hk.towerblock.eca.ed.ac.uk/list-of-estates.Photographs of Alexandras Avenue, Athens, taken by Maria Tzeli
Characterization of a prenatally assessed de novo supernumerary minute ring chromosome 20 in a phenotypically normal male
No full textAbstract Background The heterogeneous group of small supernumerary marker chromosomes (sSMCs) presents serious counseling problems, especially if they are present de novo and diagnosed prenatally. The incidence has been estimated at 1 in 1000 prenatal samples. We present a case of mosaic sSMC diagnosed prenatally after amniocentesis. The sSMC was characterized by various molecular cytogenetic techniques and determined to be a r(20) chromosome. After genetic counseling, the parents decided to continue the pregnancy, and a boy with minor phenotypic variants was born after 39 weeks of pregnancy. The case is compared with four other cases of prenatally detected r(20) mosaicism. Results Here we describe a 3 months old male child with normal pre- and postnatal development and with a de novo ring supernumerary marker chromosome in amniocytes cultures. Using new fluorescence in situ hybridization (FISH) techniques, three distinguishable sSMCs (cryptic mosaicism), all derived from chromosome 20, were observed, including ring and minute chromosomes. This heterogeneity was impossible to detect by the conventional G-banding technique or conventional FISH technique that were used before the application of new FISH techniques (subcentromere-specific multicolor-FISH [subcenM-FISH]) and a probe, specific for the 20p12.2 band. The sSMC present in 25% of the cells was present as r(20)(::p12.2~12.3->q11.1::)5/r(20;20)(::p12.1->q11.1::q11.1 >p12.1::)2/min(20;20)(:p12.1->q11.1::q11.1->p12.1:)1. The final karyotype was 47,XY,+r(20)[25%]/46,XY[75%]. Conclusion We emphasize the importance of application of molecular cytogenetics in a prenatally diagnostic laboratory and description of more cases to enable a better genetic counseling and risk evaluation.</p
Συστήματα ξύλινων φορέων στήριξης στεγών και επίπεδες οροφές στην Ελλάδα και τη Μικρά Ασία της ρωμαϊκής περιόδου
No full textΑντικείμενο της παρούσας διπλωματικής εργασίας είναι οι στέγες με ξύλινο φέροντα οργανισμό και οι προσαρτημένες ή ανεξάρτητες, λίθινες και ξύλινες επίπεδες οροφές οικοδομημάτων της ρωμαϊκής εποχής στην Ελλάδα και τη Μικρά Ασία. Από τους σκελετούς των αρχαίων στεγών σήμερα δε σώζεται σχεδόν τίποτα, εξαιτίας της φθαρτής φύσης του ξύλου από το οποίο αυτές συνίσταντο κατά κύριο λόγο, ενώ οι σχετικές επιγραφικές και φιλολογικές μαρτυρίες είναι σπάνιες και ελάχιστα διαφωτιστικές για τα γενικά, μορφολογικά και τα εσωτερικά, δομικά χαρακτηριστικά τους. Σημαντικές πληροφορίες για τις χαμένες ξυλώσεις έχουν πολλές φορές ανακτηθεί πάραυτα από τα υπόλοιπα αρχιτεκτονικά κατάλοιπα των μνημείων, επιτρέποντας στους μελετητές να υποθέσουν -με λιγότερη ή περισσότερη ασφάλεια- χαρακτηριστικά των κατασκευών. Μέχρι σήμερα, η γνώση αυτή είναι διάσπαρτη σε ανασκαφικές εκθέσεις και αρχιτεκτονικές μελέτες μεμονωμένων κτιρίων ή συγκροτημάτων, και παραμένει σκανδαλωδώς ασύνδετη με τις γενικές περιγραφές και αναλύσεις του “ελληνικού” συστήματος της δοκού επί στύλων και του “ρωμαϊκού” ζευκτού, που αναπαράγονται ακόμη σε εγχειρίδια της αρχαίας αρχιτεκτονικής. Στην πλούσια βιβλιογραφία που έχει συγκεντρωθεί γύρω από τις στέγες της ελληνικής, της ετρουσκικής και της ρωμαϊκής οικοδομικής παράδοσης, η απουσία μιας μελέτης αφιερωμένης στις ρωμαϊκές στέγες με ξύλινο φέροντα οργανισμό είναι εκκωφαντική. Η εργασία αυτή επιδιώκει να καλύψει το κενό της βιβλιογραφίας προσφέροντας μια ολοκληρωμένη μελέτη των ξυλοστήρικτων στεγών στη ρωμαϊκή Ελλάδα και Μικρά Ασία μέσω του ελέγχου και της συμπλήρωσης της υπάρχουσας σχετικής γνώσης και της παραγωγής πρωτότυπων ειδικών και γενικών συμπερασμάτων.This study seeks to examine the timber framed roofs and the attached or independent, stone or wooden flat ceilings of Roman Greece and Asia Minor. Today, almost nothing survives from the ancient structures, due to the perishable nature of wood of which they mainly consisted, while any relevant epigraphic and philological evidence is scarce and not very helpful for understanding their morphological and structural features. However, important information about the lost frameworks has often been gained directly from other surviving architectural members, allowing scholars to make assumptions about their forms. To this day, this knowledge is scattered in excavation diaries, archaeological reports and architectural studies of individual buildings or complexes, and remains scandalously unconnected with the general descriptions and analyses of the "Greek" post-and-lintel system and the "Roman" truss, which are still reproduced in handbooks of ancient architecture. In the rich literature around Greek, Etruscan and Roman roofs and building traditions, the absence of a study focused on Roman timber roofs is deafening. This thesis seeks to fill this gap by providing a comprehensive analysis of timber roofs in Roman Greece and Asia Minor, and make an original contribution to knowledge through the critical evaluation of previous studies and derivation of new conclusions
Ruins: the past in the present
No full text79 σ.Στην διάλεξη αυτή μελετώνται τα ερείπια ως υποδειγματικές περιπτώσεις του τρόπου με τον οποίο η αρχιτεκτονική βοηθά τον άνθρωπο να κατανοήσει τον κόσμο και τον εαυτό του. Αφού πρώτα εξεταστεί η αξία των ερειπίων μέσα από ένα θεωρητικό, φιλοσοφικό και κοινωνιολογικό πρίσμα, μελετάται στη συνέχεια το ζήτημα της “τύχης” τους: «Πρέπει, ή όχι, να παρεμβαίνουμε και να προσπαθούμε να “σώσουμε” το αποσυντιθέμενο κτίσμα; Και αν ναι, με ποιον τρόπο;»
Μέσα από τις ιδέες, τις έννοιες και τις θεωρίες για τα ερείπια, με τη βοήθεια ιστορικών γεγονότων και προσώπων, επιχειρούμε να κατανοήσουμε τη σημασία που έχουν τα ερείπια στις κοινωνίες μας και να πάρουμε θέση στο πώς πρέπει να αντιμετωπίζονται από τους αρχιτέκτονες, αλλά και την κοινωνία γενικότερα, ώστε όχι μόνο να διατηρείται η αξία τους, αλλά και να αναδεικνύεται στο έπακρο.In “Ruins: The Past in the Present” I will study ruins as exemplary cases of the way architecture helps the man understand the world and himself. After first examining the value of ruins through a theoretical, philosophical and sociological standpoint, I will then deal with the question of their "destiny": should we, or should we not, intervene and try to "save” the decaying structure? And if so, in what way?
Through a “journey” in ideas, notions and theories on ruins, associated with historic events and personalities, I will attempt to gain understanding of the significance of ruins and take a stand on how they should be treated (by architects, and society in general), so that their significance is not only preserved, but also manifested to the fullest

Analysis of chemical bonding of the ground and low-lying states of Mo2and of Mo2Clxcomplexes, x = 2-10
No full textIn this study, we perform accurate calculations via multireference configuration interaction and coupled cluster methodologies on the dimolybdenum molecule in conjunction with complete series of correlation and weighted core correlation consistent basis sets up to quintuple size. The bonding, the dissociation energies, and the spectroscopic parameters of the seven states that correlate with the ground state products are calculated. The ground state has a sextuple chemical bond, and each of the calculated excited states has one less bond than the previous state. The calculated values for the ground X1ςg+ state of Mo2 have been extrapolated to the complete basis set limits. Our final values, re = 1.9324 Å and De (D0) = 4.502 ± 0.007(4.471 ± 0.009) eV, are in excellent agreement with the experimental values of re = 1.929, 1.938(9) Å and D0 = 4.476(10) eV. Mo2 in the ςg+13 state is a weakly bound dimer, forming 5s »5pz bonds, with De = 0.120 eV at re = 3.53 Å. All calculated excited states (except ςg+13) have a highly multireference character (C0 = 0.25-0.55). The ordering of the molecular bonding orbitals changes as the spin is increased from quintet to septet state resulting in a change in energy separation ΔS,S-1 of the calculated states. The quite low bond dissociation energy of the ground state is due to the splitting of the molecular bonding orbitals in two groups differing in energy by ∼3 eV. Finally, the bond breaking of Mo2, as the multiplicity of spin is increased, is analyzed in parallel with the Mo-Mo bond breaking in a series of Mo2Clx complexes when x is increased. Physical insight into the nature of the sextuple bond and its low dissociation energy is provided. © 2022 Author(s)
