XVIII International Coal Preparation Congress
Changes in economic and market conditions of mineral raw materials in recent
years have greatly increased demands on the ef fi ciency of mining production. This
is certainly true of the coal industry. World coal consumption is growing faster than
other types of fuel and in the past year it exceeded 7.6 billion tons. Coal extraction
and processing technology are continuously evolving, becoming more economical
and environmentally friendly. “ Clean coal ” technology is becoming increasingly
popular. Coal chemistry, production of new materials and pharmacology are now
added to the traditional use areas — power industry and metallurgy. The leading role
in the development of new areas of coal use belongs to preparation technology and
advanced coal processing. Hi-tech modern technology and the increasing interna-
tional demand for its effectiveness and ef fi ciency put completely new goals for the
University. Our main task is to develop a new generation of workforce capacity and
research in line with global trends in the development of science and technology to
address critical industry issues.
Today Russia, like the rest of the world faces rapid and profound changes
affecting all spheres of life. The de fi ning feature of modern era has been a rapid
development of high technology, intellectual capital being its main asset and
resource. The dynamics of scienti fi c and technological development requires acti-
vation of University research activities. The University must be a generator of ideas
to meet the needs of the economy and national development. Due to the high
intellectual potential, University expert mission becomes more and more called for
and is capable of providing professional assessment and building science-based
predictions in various fi elds.
Coal industry, as well as the whole fuel and energy sector of the global economy
is growing fast. Global multinational energy companies are less likely to be under
state in fl uence and will soon become the main mechanism for the rapid spread of
technologies based on new knowledge. Mineral resources will have an even greater
impact on the stability of the economies of many countries. Current progress in the
technology of coal-based gas synthesis is not just a change in the traditional energy markets, but the emergence of new products of direct consumption, obtained from
coal, such as synthetic fuels, chemicals and agrochemical products. All this requires
a revision of the value of coal in the modern world economy
Planning cities for the post-carbon age : a metabolic analysis of the urban form
[Resumen] El siglo veinte ha sido la edad de las ciudades, en la cual han experimentado la mayor expansión de su historia. La concentración
de personas y actividades ha permitido un avance tecnológico sin precedentes, una larga etapa de prosperidad económica y el
desarrollo de la actividad cultural. Cada día, miles de personas emigran desde sus hogares rurales en busca de las oportunidades
que ofrece la metrópolis. Sin embargo, el triunfo de la ciudad ha sido a costa de la degradación de otros parajes, externos a ella,
ya que absorben recursos desde distancias cada vez más lejanas. Las ciudades han crecido como sistemas voraces, basadas
en el consumismo, por lo que requieren un suministro constante de materiales, agua, alimentos y energía para sostener su
actividad y economía. Como tema central de investigación, las ciudades han sido estudiadas desde casi todas las perspectivas
posibles. Algunas investigaciones previas han propuesto una analogía ecológica para medir los flujos del sistema urbano, lo
que supone entender la ciudad como un ecosistema con un metabolismo característico. Este sería un primer paso para discernir
las variables espaciales que influyen en el consumo urbano de recursos externos. Sin embargo, estos estudios todavía no han
podido establecer de forma inequívoca la conexión entre la estructura física de la ciudad y su comportamiento ambiental. La
abstracción de los postulados teóricos y las interferencias de múltiples factores en el análisis empírico han limitado el número
de certezas en la ciencia urbana. El objetivo de esta tesis es explorar los vínculos entre forma urbana y los patrones de demanda
de energía, mediante la combinación de la capacidad de exploración de modelos teóricos con el pragmatismo derivado del
estudio de casos reales. Para ello, se ha elaborado un modelo de evaluación energética a escala urbana, tratando de responder a la
carencia de instrumentos específicos que permitan integrar análisis y el diseño. Esta aplicación se prueba y aplica en diferentes
escenarios derivados de los casos de estudios. Las experiencias de regeneración en los Docklands de Londres y el Poblenou de
Barcelona proporcionan un marco real para entender la lógica de las transformaciones morfológicas en las ciudades existentes,
introduciendo nuevas variables y aspectos, aunque manteniendo el foco principal de la investigación en la relación entre energía
y forma urbana.[Resumo] O século vinte foi a era das cidades, na cal experimentaron a maior expansión da súa historia. A concentración de persoas e

vínculos entre a forma urbana e os patróns de demanda de enerxía mediante a combinación da capacidade de exploración dos
modelos teóricos coas aprendizaxes derivadas do estudio de casos reais. Elabórase un modelo de análise enerxético urbano para
responder á carencia de instrumentos específicos de planificación que permitan integrar a análise e o deseño. Esta aplicación
próbase e aplícase en diferentes escenarios de forma urbana derivados dos casos de estudos. As experiencias de rexeneración
nos Docklands de Londres e o Poblenou de Barcelona proporcionan un marco real para entender a lóxica das transformacións
morfolóxicas nas cidades existentes, introducindo novas variables e aspectos máis amplos, ainda que mantendo o foco principal
da investigación na relación entre enerxía e forma urbana.[Abstract] The 20th century has been the age of cities, as they have experienced their greatest expansion over history. The concentration of
people and activities has enabled unprecedented technological advance, economic prosperity and the enhancement of culture.
Thousands of people move every day from their rural homes, looking for the opportunities provided in the metropolis. However,
the triumph of the city has been achieved at the expense of external environments, as they draw to themselves resources from
further and further distances. Cities have grown as voracious systems, highly based on consumerism thus requiring massive
flows of goods, water, food and energy to sustain their activities. As a central field of research, cities have been studied from all
possible perspectives. Previous investigations have proposed an ecological analogy to measure the flows of the urban system,
understanding the city as an ecosystem with a characteristic metabolism. It was meant as a first step to discern the spatial variables
that influence urban consumption patterns. Nevertheless, these attempts to establish a connection between the performance of
cities and their physical structure have been inconclusive so far. The abstraction of theoretical postulates and the interferences of
multiple factors in empirical observations have limited the number of certainties in current urban science. The aim of this thesis
is to explore the links between the urban form and energy demand patterns by combining the exploratory capacity of theoretical
models with the learning outcomes from real case studies. As new planning instruments are needed to integrate analysis into
design, an urban energy mode and tool has been worked out. The application was then tested and applied on alternative urban
form scenarios, derived from the case studies. The regeneration experiences in London Docklands and Barcelona Poblenou
provide a framework to understand the logic of morphological transformations in existing cities, introducing further variables
and broader issues while keeping the control on the primary focus of the investigation: the relation between energy and urban
form
Housing quality and lost (public) space in Croatia
IN ENGLISH: In the post-socialist period and within the current social transition context, urban and rural Croatia has, just like other transition countries, experienced many changes in the social structure and space. One example is the housing quality which is a replica of the situation in the Croatian society and has also undergone some major changes. Socially oriented housing construction co-financed by the state and the cities is in an unfavourable position compared to private housing construction. In the last twenty years the amount of the social housing construction has been only a minor part of the total contruction work in the country. For instance, out of nine newly planned residential housing developments in Zagreb, the capital city, only three have been completed and the work on the rest of them has stopped and is unlikely to continue. Private construction work prevails especially on the edge of the city and is characterised by high density housing. This type of housing construction doesn't benefit the majority of citizens in search of accommodation (price per square meter is too high, low-quality building). There is also a big problem of the community facilities (primary and secondary infrastructure, schools, kindergartens, playgrounds, green areas, sidewalks, public transport etc.). The existing globalisation-transition circumstances of the Croatian society corroborate the fact which experts of various profiles often point out: ignoring the process of (urban) planning will irreparably damage the space. The city transformation shows the absence of comprehensive urban planning which results in an ever increasing number of random buildings which do not fit in the surroundings. This leads up to yet another important issue – the shrinking and, in some cases, disappearance of public space which becomes the “lost space“. In recent years there has been a lot of building in the city core and on the edge which does not quite fit in the existing urban structure, image or the skyline of the city. The current situation in the process of planning can be characterized as a conflict and imbalance between the powerful actors (mostly political and economic) and less powerful actors (mostly professional and civil). The actors who have the political power and influence and the ones who possess the capital are forming an “alliance” between two important layers of the social structure. The lack of civil and professional actors, “lost spatial actors”, and therefore of civic aggregation is also present and that is also the cause of public space “disappearance” and undermined process of public participation. --------------- IN CROATIAN: U postsocijalističkom razdoblju i trenutnom tranzicijskom kontekstu urbana i ruralna Hrvatska su, kao i ostale tranzicijske zemlje, doživjele mnoge promjene u društvenoj strukturi i samom prostoru. Na primjeru kvalitete stanovanja kao replike stanja u hrvatskom društvu mogu se vidjeti značajne promjene. Društveno usmjerena stambena izgradnja sufinancirana od strane države i gradova je stoga rjeđa i u nepovoljnijoj je situaciji prema privatnoj stanogradnji. Zadnjih dvadeset godina udjel socijalne stambene gradnje je zanemariv u ukupnoj izgradnji na razini zemlje. Primjerice, od devet planiranih stambenih naselja izgrađenih po modelu POS-a u Zagrebu samo su tri i završena. Na ostalima je proces gradnje zastao i ne čini se da će se privesti kraju. Privatna je gradnje prisutnija, posebno na rubovima grada, a obilježava je visoka gustoća gradnje. Ovakav tip gradnje ne odgovara većini stanovnika koji su u procesu potražnje stambene nekretnine (visoka cijena kvadratnog metra, a slaba kvaliteta gradnje). Postoji također i problem nedostatne opremljenosti susjedstva (primarna i sekundarna infrastruktura, škole, vrtići, igrališta, zelene površine, pješačke staze, javni transport itd.). Navedene globalizacijsko-tranzicijske okolnosti hrvatskog društva potvrđuju ono što eksperti različitih profila ističu, a to je da će ignoriranje procesa (urbanog) planiranja nepovratno uništiti prostor gradova. Ovakve transformacije pokazuju nedostatak sustavnog urbanog planiranja što rezultira sve većim brojem zgrada koje se ne uklapaju u neposrednu okolinu. To nadalje dovodi do drugog važnog aspekta – smanjivanja i u nekim slučajevima, nestanka javnog prostora koji postaje „izgubljeni prostor“. Posljednjih je godina izgrađen velik broj zgrada, i u središtu i na rubovima grada, koje se ne uklapaju u postojeću urbanu strukturu, izgled ili vizuru grada. Ovakvu situaciju obilježavaju sukob i neravnoteža između moćnijih društvenih aktera (većinom političkih i ekonomskih) i onih manje moćnih (većinom profesionalnih i civilnih). Politički i ekonomski akteri se često povezuju u „savez“ dvaju najjačih u društvenoj strukturi. S druge strane nedostatak utjecaja civilnih i profesionalnih aktera kao „izgubljenih prostornih aktera“ dovodi do „nestanka“ javnih prostora te smanjenja važnosti procesa participacije (sudjelovanja javnosti)
Proceedings of the 23rd International Congress of Byzantine Studies : Round Tables
Following the 23rd International Congress of Byzantine Studies, the Organizing Committee
decided to produce an online publication of Proceedings from the Round Tables. According to the
official title of the congress, Byzantium - a World of Changes, AIEB together with the Organizing
Committee, have decided to implement some changes to the concept of the Round Tables. The aim
of these changes were to encourage discussion at the Round Tables by presenting preliminary papers
at the website in advance. The idea was to introduce the topic and papers of the individual Round
Tables that would be discussed, first between the participants, and then with the public present.
Therefore, the conveners of the Round Tables were asked to create Round Tables with no more than
10 participants. They collected the papers, which were to be no longer than 18,000 characters in one
of the official languages of the Congress and without footnotes or endnotes. Conveners provided a
general statement on the goal of each roundtable and on the content of the papers.
The present volume contains papers from 49 Round Tables carefully selected to cover a wide
range of topics, developed over the last five years since the previous Congress. The topics show
diversity within fields and subfields, ranging from history to art history, archeology, philosophy,
literature, hagiography, and sigillography. The Round Tables displayed current advances in research,
scholarly debates, as well as new methodologies and concerns germane to all aspects of international
Byzantine studies.
The papers presented in this volume were last sent to the congress organizers in the second
week of August 2016 and represent the material that was on hand at that time and had been posted
on the official website; no post-congress revisions have occurred. We present this volume in hope
that it will be an initial step for further development of Round Tables into collections of articles
and thematic books compiled and published following the Congress, in collaboration with other
interested institutions and editors. With this volume, the organizers signal their appreciation of
the efforts of more than 1600 participants who contributed, both to the Round Tables and to the
Congress in general
