All the energy that humans use comes directly or indirectly from the sun. In the
beginning, humans used their own strength, which came from their food. That was the
only energy source for hundreds of thousands of years, until fire was discovered
350,000 years ago, burning wood as fuel. They had discovered the biomass as energy
source.
Seventy percent of the global population is expected to live in cities by 2050, occupying more land and generating more emissions. The effect of urban emissions reduces the capacity of natural ecosystems to function effectively while at the same time negatively impacting human health and well-being. Therefore, the sustainable management of urban areas is crucial for the long-term sustainability of the human economy. The management strategies should adopt a new systemic perspective that considers cities as socio-ecological systems characterised by complex human-nature interactions. This perspective is also based on the shift from the traditional “black box” urban metabolism models, accounting for the input of resources and output of wastes and products, to the network models capable of unfolding the internal metabolism of cities. The theoretical part of the work covers two interdisciplinary research fields: Ecological Economics and Industrial Ecology, combined in a network science methodology .
Firstly, the bibliometric analysis of global scientific literature on urban metabolism was performed to identify the temporal developments and new areas for investigating the metabolism of the urban systems. In the empirical part, the environmental accounting and the multiple methods of network science methodology were integrated to estimate the environmental costs, metabolic efficiency and self-sufficiency, and impact of each sector in urban socio-ecological systems. The research corresponds to the 11th and 12th Sustainable Development Goals. It contributes to developing sustainable resource management strategies for Sustainable Cities and Communities by identifying inefficient or unsustainable resource consumption patterns. The first case study focused on estimating total emergy use in the Vienna Region. The results show that “mining” and “agriculture” are not prioritised in terms of investment by the Vienna Government. In addition, the ecological network analysis was applied to analyse the structural and functional attributes of Vienna’s urban metabolic system to identify weaknesses in the system's ecological hierarchy and relationships and the sectors behind these weaknesses. The results show that “wholesale and retail” and “energy” sectors are responsible for the low financial support to producers (agriculture and mining) by the tertiary industries. The other study found that the footprint of final products by “agriculture” became larger when an emergy-evaluated version of direct carbon emissions was used.
A multicriteria approach integrating the input-output and the emergy accounting methods could be a valuable tool in investigating socio-ecological interactions, allowing a comprehensive understanding of environmental and socio-economic flows exchanged between industrial sectors and the environment. The integration of environmental accounting with the multiple methods of network science methodology allows for the investigation of internal metabolic pr

The purpose of this research was to measure the quantity and quality of information provided by the five major Italian newspapers - La Repubblica, Il Corriere della Sera, Il Messaggero, Il Sole 24 Ore and La Stampa - on the theme of the return of nuclear power in Italy by analyzing the articles published between 2006 (When electric utility Enel bought the Slovak Slovenské Elektrárne,) and 2009 (when Law 99/2009 introduced the possibility to build nuclear plants in Italy for energy generation)
STUDY OF THERMAL MAPPING FOR HEALTH MONITORING OF GAS TURBINE BLADEIJRISE Journal
Thermal mapping for health monitoring of gas turbine is essential as modern day gas turbine subjected to very
high temperature applications, gas turbines are used extensively for aircraft propulsion, land -based power
generation, and industrial applications. Developments in turbine cooling technology play a critical role in
increasing the thermal efficiency and power output of advanced gas turbines. Gas turbine blades are cooled
internally by passing the coolant through several rib-enhanced Some tine passages to remove heat conducted
from the outside surface. External cooling of turbine blades by film cooling is achieved by injecting relatively
cooler air from the internal coolant passages out of the blade surface in order to form a protective layer between
the blade surface and hot gas-path flow. For health monitoring of gas turbine blade, this presentation focuses on
the effect of critical zone and hot spot along temperature distribution by using thermal paint. The comp utational
flow and heat transfer results are also presented. This presentation includes unsteady high free -stream
turbulence effects on film cooling performance with a discussion of detailed heat transfer coefficient and filmcooling
effectiveness distributions for standard and shaped film-hole geometry using the newly developed
transient liquid crystal image method.
This E-nano Newsletter issue contains the Strategic Research Agenda for Nanophononics, one of the main outputs of the EUPHONON coordination action (www.euphonon.eu); EU project with the mission to build a European Community for Nanophononics. The main objective of the Nanophononics Strategic Research Agenda is to define the role and impact of nanophononics in today’s society and in the industry. It is expected to give insight to the potential of the field to improve the properties of current information technology devices, enhance energy efficiency and advance the health and well-being and safety. In addition research highlights from top-level research institutions worldwide such as MANA/NIMS (Japan) and CIC nanoGUNE (Spain) are presented.
This paper seeks to disaggregate concerns about energy security within the wider European neighborhood from the nation-state to the household, and particularly to poor households in the transition and developing economies of the former Soviet Union. It argues that two decades of under-investment in Soviet-era energy, water, and communal service infrastructures threaten significant reductions in access to these services in the poorer countries of this region, particularly Tajikistan and Kyrgyzstan. These problems are manifesting themselves both in terms of growing physical restrictions on access to energy, water, and communal service networks in these countries, and in terms of rapid growth in tariffs for these services which could price some vulnerable households "out of the market". The paper also suggests that these problems are apparent to various degrees in a number of other former Soviet republics, and that the impact of the global economic crisis is likely to exacerbate these problems. By calling attention to growing household vulnerability to energy and water insecurities, particularly in Central Asia, the paper seeks to bring an economic development perspective to bear on energy policy debates in the wider European region.

Application of the ELECTRE III Method at the Moroccan Rural Electrification P...IJECEIAES
As part of the integrated strategy of the Moroccan state aimed at the social and economic development of the Moroccan rural community, an electrification program has been in place since the 90s. This program, called PEGR, has for main objective the improvement of the electrification rate for the national rural world. Given the large number of villages to be electrified and the colossal budget that will induce, several criteria have been retained to objectively distinguish the villages with the highest priority for electrification. Given the nature of this problem to be solved, which is a multicriteria decision aid problem, we propose in this article to use the multicriteria aggregation method ELECTRE III to rank the villages from the highest priority to the lowest priority for the electrification.

Dr. Elena Helerea - Energy Trilemma: Past and Future
The end of the 20th century was the period of technological propulsion and beginning of
the intensifying danger of destroying ecologic equilibrium. The accumulation of goods and
services did not achieve well-being, and led to different models for socio-economic
development. The new concept of sustainable development appeared in the Brundland Report
“Our Common Future” (1987, World Commission on Environment and Development), and
accepted in 1992 at the Conference of the United Nations with respect to Environment and
Development (Rio de Janeiro).
Implementation of this concept, which underlined that humanity has to pass to a
sustainable environmental existence, began in the energy sector. The successful transition to an
environmentally sustainable energy system included photovoltaic systems, decentralized energy
generation, retrofits of existing buildings, adoption of low-carbon technologies, and electric
vehicles to service mobility needs. The World Energy Council proposed an efficient assessment
tool of implementing the energy sustainability based on three factors: energy security, energy
equity, and environmental sustainability. Balancing these three goals constitutes an energy
trilemma (Energy Building Code World Energy Council’s case study, 2016, ECOTECH).
The paper analyzes the global evolution of the 2017 energy trilemma indexes with a case
study of Romania’s progress and efforts in ensuring a balanced energy trilemma and comparison
with the results of other European countries. Romania's scores well, with energy security strong
at 7th
globally and has already reached and exceeded its EU-mandated target of a 24% share of
renewables (water, wind and solar energy) in gross energy consumption. Renewable energy’s
future is uncertain due to recent changes to the country’s green certificate scheme and feed-in
tariff system for small renewable energy producers, adopted in 2015. Energy policy should
focus on maintaining and improving the existing energy supply and transmission structure,
which will need large investments to raise Romania’s energy equity score.

Dr. Dorin Dusciac - Hydropower Infrastructure on the Upper Course of the
Dniester River: Historical Evolutions and Perspectives for the Ukraine –
Republic of Moldova Relations
Management of hydropower infrastructure on transboundary water courses is subject to a
number of international treaties, conventions and regulations. Hydropower plants usually have a
non-negligible impact on the ecological systems of the concerned river basin, thus
environmental issues are at the core of the above-mentioned legal documents. As part of a
system of international relations in continuous change, “environmental diplomacy” is a key
component of modern inter-state paradigm. In this article, we present the development of
hydropower generation infrastructure on the upper course of the Dniester River, from the 1970’s
to present times. Since the independence of Ukraine and Republic of Moldova in 1991, the
Dniester became a transboundary water course, with significant subsequent change of the river’s
basin management rules. Over the past 25 years, Ukraine is seeking to tackle its electric power
generation deficit and to increase the percentage of renewable energy in its energy mix. In its
Western region, these goals can be achieved by substituting polluting coal-fired thermal plants
with new hydropower facilities. Six new hydropower plants are planned to be built on the upper
course of the Dniester over the next ten years. These plans raise a number of serious concerns,
especially from the neighboring Republic of Moldova (including its separatist Transnistrian
region, which will be directly affected). In this case study, we present the evolution of the legal
regulatory framework, from Soviet-era centralism to new geo-political reality created by both
countries’ accession to the Energy Community Treaty (2010) and the implementation of the
acquis communautaire, as part of each country’s Association Agreement to the European Union
(2014). Major changes of several characteristics of the region (demography, state of ecological
systems, geo-political aspects, etc.) over the past decades are outlined with supporting evidence.

Dr. Mircea Ivanoiu; Professor Alexandre Herlea - Exploitation of Hydraulic
Energy in Rural Traditional Technology, in Romania. Resemblance and
European Synchronism
Without being a continental or international exception, Romania represents an area of
early usage of hydraulic energy as primary energy. Due to the fact that such machines used in
times, previous to modern age are achieved on intuitive and empirical bases, for personal and
community usage in rural areas, ethnography was the science that dealt with their study. The
paper intends to present the usage of water energy in some peasant autarchy household activities
and compares the machines used in Romania with those used in other parts of Europe (Valais,
France).
Constructive and functional solutions in some fields of activity are described in this
paper, namely:
– in food industry, the processing of grains to obtain flour;
– in textile industry, the processing of beaten, carded and washed cloths;
– in wood industry, for furniture and building (board and timber)
In analyzing these examples of empirical exploitation of water I had in mind the pages
written by known historians of science and technology in the field (Maurice Daumas, Ian
McNeil Charles Singer) In the first half of the last century, engineers - builders of classical
hydraulic turbines (Pelton, Francis and Kaplan) made some attempts of theoretical foundation of
the functioning of old hydraulic wheels. We will analyze the proposals of PhD Eng. Dorin
Pavel, the most known Romanian designer of hydraulic machines and equipment for the hydro
energetic plants at the beginning of this industry in Romania. The paper is illustrated, besides
historical photos, with some quite recent images of still functioning or abandoned equipment, on
small rivers in the southern Transylvania.

Dr. Andreas Wild - Rise and Fall of the Romanian State-owned
Micro/nanoelectronics
Micro/nanoelectronics started with the invention of the integrated circuit in 1958,
enabled by the discovery of the semiconductor transistor in 1947. Its centre of gravity was in the
Silicon Valley, but it was also developed elsewhere, including behind the Iron Curtain, probably
because Lenin himself recognized the propaganda potential of the radio technology that later
relied upon semiconductors. Romania nationalised its industry and run eight five-year plans
starting in 1951, building an electronic ecosystem with a rather performant educational system;
academic and institutional research; and industrial entities in components (including
micro/nanoelectronics), equipment manufacturing, and services - exporting electronic products
in COMECON, Western Europe, U.S.A. Israel, etc. In 1989, there were 33 entities, employing a
workforce of about 20,000.
In micro/nanoelectronics, Romania acquired licenses and expanded them with own
developments; started an international conference on semiconductors; had specialists publishing
in peer-reviewed conferences and journals; and granted patents. Even its defectors made
brilliant careers. This anecdotic evidence suggests that Romanian micro/nanonelectronics was
not without merit. However, technical competencies could not overcome its structural
handicaps: excessive vertical integration, to satisfy a domestic demand too small to generate
economy of scale; inapplicability of economic metrics in a State-owned economy with
nonconvertible currency, reporting fictitious parameters like the “global production”; lack of
basic skills in marketing and management in enterprises obliged to implement decisions from
the State Council for Plan, the State Council for Prices or Communist Party directives. After the
communist regime was ousted in 1989, the Romanian institutional research survived, but its
micro/nanoelectronics collapsed. The industry privatisation, hampered by insufficient market
understanding and by alleged corruption, could rescue only a small part of the assets.
Nonetheless, the surviving elements could be the starting point of a renewal, if the country
would make this strategic decision.

Professor Alexandre Herlea - Petre (Pierre) Sergescu, Science Historian and
Promoter of the Discipline
Born in 1893 in Romania, Petre Sergescu, a mathematician and historian of science,
played a major international role in the institutional organization of the history of science after
the Second World War. Graduated (1916) from the Faculties of mathematics and philosophy of
the University of Bucharest as well as from the Conservatory of Music, he continued his studies
in Paris. Here he was a student at the Ecole Normale Supérieure where he obtained in 1922 his
degree in Mathematics and followed the courses of history of Mathematics of Pierre Boutroux at
the Collège de France. Back in Romania, he passed his doctorate with a brilliant thesis and was
appointed in 1926 professor of analytical geometry at the University of Cluj where he founded
the journal „Mathematica” (Bilingual review: French, Romanian) and organized the first
Congress of Romanian mathematicians. In 1943, P. Sergescu was appointed professor at the
Polytechnic School of Bucharest, whose President he became in January 1946. But in August of
the same year, he took refuge in France, where he had often stayed in the period between the
two World Wars and where he married a writer of Polish origin, Marie Kasterska. Together they
hosted a prestigious cultural salon in Paris, in the Quartier Latin, until the end of 1954, the year
of his death.
From 1932, P. Sergescu participated in the activity of the group of Sciences historians
formed around Aldo Mieli who had created, in 1929, "The International Academy of the History
Science (IAHS) where he himself became a member in 1935. He had already published a lot in
the field including the book "Gandirea Matematica” (Mathematical thought) crowned by the
Romanian Academy and "Mathematical Sciences in France" crowned by the French “Académie
des Sciences”.
From 1946 on, while being very active in the Romanian emigration in Paris (President of
the academic institution "The Royal Foundations University of Charles I" created by the
Romanian exiles in 1951), P. Sergescu is the driving force behind international collaboration in
the History of Science. It began with the resuscitation of IAHS which had interrupted its
activities during the war and of which he was, since 1937, Vicepresident; He was elected
President in 1947 and Perpetual Secretary in 1950. This institution acts, in parallel with
efficiency, for the establishment, within the framework of UNESCO and of The International
Council of Scientific Unions (ICSU), institutions created after the Second World War, of The
UIHS (International Union of History of Sciences) of which he was elected Secretary-General in
1947, the year of its creation. The same year he became editor-in-chief of the "International
History of Science Archives" whose first issue had just appeared and of which he became
director in 1951.
However, in Paris, P. Sergescu also developed other activities in the field of science, its
history, teaching and dissemination. From 1946 onwards, he organized the annual meetings of
the Science history section of „The French Association for the advancement of Science –
AFSA”, founded the Mathematic history Seminar at The Institute Henri Poincaré and
participated in the setting up of monthly conferences in Discovery Palace He also played an
important part in the realization of several exhibitions. His activities and achievements received
general recognition; He became a member of several academies and learned societies and
received distinctions including the Légion d’Honneur.
