Dezvoltarea durabilă a oraşelor post-comuniste – studiu comparativ România/ Franţa

Author(s): Maria Militaru / Language(s): Romanian Publication Year: 0

This article aims to explore sustainable development pathways in the housing sector of post-communist countries from the former Eastern Bloc, in the context of the ongoing growth of major urban centers, contemporary changes and socio-economic transformations within cities. To establish the limits of this brief research, we will examine sustainable development through social, economic, political and demographic aspects. Additionally, to enhance our understanding of sustainable housing development, we will apply a multidisciplinary approach to two case studies: Romania and France. By adopting this multidisciplinary perspective, we will compile and analyze the key events along a timeline that underlie major paradigm shifts in each researched domain. Comparing these events in terms of temporality and intensity will provide insights into the parameters under which sustainable housing developments should evolve.

Analiza umidităţii argilei proaspete prin tehnici de procesare a imaginii

Author(s): Alexandrina-Elena Andon / Language(s): Romanian Publication Year: 0

Clay can absorb and release moisture faster and to a greater extent than any other building material. The normal moisture content that unsaturated clay can absorb is 5% to 7% by weight. Numerous studies have focused on determining soil moisture in a practical, fast, non-destructive and relatively inexpensive way by evaluating the effectiveness of artificial neural networks (ANNs). The image processing method for determining moisture involves using artificial neural networks to accurately determine the moisture content of soils, based on the assumption that soils change color with water content. Disturbed samples of raw clay taken from the Vaslui region, Codăești village, were used for training and testing ANN. Input data were collected in the laboratory from samples subjected to different water contents, consisting of color photographs, taken with a 24.1 megapixel digital camera. The higher the water content, the darker the sample's color. A multi-layer neural network was created with 3 neurons in the input layer, each neuron representing the pixel area for the three colors (red, green and blue) resulting from the segmentation of the image into regions, with a single hidden layer and a single output layer. The ANN output consisted of the soil moisture value, determined for each soil sample by classical methods.

Risk management approaches in the development of sloped areas

Author(s): Vladimir POLCANOV,Alexandru CIRLAN,Alexandru RASCOVOI,Alina Polcanova / Language(s): English Publication Year: 0

The main regularities determining the strength of Sarmatian clays, which constitute the majority of slopes in Republic of Moldova were examined. The peculiarities of soil behaviour under conditions of creep deformation were studied. An assessment of the strength of collapsible soils, which are widespread practically on the whole territory of the republic, was provided. The conditions for changes in their properties upon wetting of the collapsible layer was identified. The possibility of eliminating soil settlement using the RG-installation was studied. New data characterizing the physical and mechanical properties of collapsible silty clays compacted in this way have been obtained. The reliability of using the RG-installation to increase the bearing capacity of foundations has been proven. Results of the assessment the long-term stability of excavation slopes at a section of the M21 Chisinau-Dubasari roadway were presented. Recommendations were made for reducing landslide risk and mitigating soil settlement. The article was based on field and laboratory research, as well as calculations using the finite element method (FEM) implemented in the PLAXIS software package. The theoretical foundation is based on the key principles of the physico-technical theory of creep developed by Prof. N. Maslov.

De la tradiţie la sustenabilitate: elemente de zidărie din materiale locale

Author(s): Aurelia Bradu,Alexandrina-Elena Andon,Maria Simona BLAJUT,Marius MÂRŢ / Language(s): Romanian Publication Year: 0

The accelerated climate changes observed in recent years demand urgent attention and actions to counteract their catastrophic effects. These phenomena affect the population globally, especially those living in vulnerable areas who face potential relocation in the near future. The construction sector has a significant contribution, representing 32% of global energy consumption and 19% of greenhouse gas emissions. A sustainable approach involves gradually replacing traditional construction materials, particularly those containing cement, with eco-friendly alternatives. One potential solution for non-structural elements is the use of masonry components made from clay and lime composites enriched with vegetable waste, such as hemp stalks. The combination of hemp, clay, lime and water forms a natural, lightweight bio-composite suitable for use in a variety of climates. This paper examines the key properties of masonry elements made from lime composite with vegetable waste, focusing on density, compressive strength, and thermal and acoustic performance.

Analiza privind beneficiile integrării BIM în economia construcţiilor

Author(s): Alexandru IONIŢĂ,Madalina Stoian / Language(s): Romanian Publication Year: 0

In the context of accelerating digitization in the construction industry, Building Information Modeling (BIM) has emerged as an innovative technology that is transforming traditional design and execution processes. This study examines the benefits of BIM integration over conventional methods, through a comparative analysis of a project realized in 2D using AutoCAD and 3D modeling through Autodesk Revit. Utilizing the original data from Dormitory 7 at the Technical University of Construction in Bucharest, the research evaluated the time and cost differences for each method. The results indicate that BIM contributes significantly to saving time and materials, due to its superior accuracy and ability to reduce human errors in the design and execution process. Although BIM adoption requires a considerable initial effort, the long-term benefits include cost optimization and better resource management, which underlines the importance of further modernization through BIM integration in the Romanian construction sector.

The Impact of EU Shadow Liabilities on Member States; Inflation and Currency Effects

Author(s): Gordon Kerr / Language(s): English Publication Year: 0

Based substantially on the analysis of Bob Lyddon, with whom the author has worked on several papers and reports about EU financial stability, this paper summarises the scale and scope of unrecorded and unreported liabilities that are hidden not so much by weak accounting rules but more by the careful and deliberate design. Some institutions are backed only by Eurozone member states, some by all EU member states. The effect of this practice of creating and hiding liabilities is estimated at almost doubling the combined General Government Gross Debt of the EU member states. This matters; bad for embedded but as yet relatively low inflation, and bad for the stability of the euro as a currency.

Model of a Neutralised Currency and Exchange System for Central Banks

Author(s): Peter Brass / Language(s): English Publication Year: 0

This paper describes a super-neutralised complementary currency as a currency and exchange system for central banks, independent of national interests which describes our world as a finite resource. The goal is a stable, crisis-proof financial system that meets the challenge of ecological and economic sustainability. In fact, it is more a unit of measurement then money, like the primal metre in Paris, but for money. Just as a uniform measure of length is important for natural sciences and technology, a fixed reference value for money can act like a Copernican turning point and could offer many benefits. This application leads to equality of weak and strong currencies. It enables weak economies to pursue an independent monetary policy and simplifies the path to monetary unions. It prevents speculation in the system. It creates a constraint to gradually reduce trade imbalances and enables over-indebted countries to get out of the debt trap.

HISTORICAL AND POLITICAL ASPECTS OF RUSSIA - SERBIA RELATIONS

Author(s): Miroslav Jovanović,Alexey Timofeev,Žarko Petrović / Language(s): English Publication Year: 0

In late 2008 and in early 2009 heated debates were held in the Serbian public regarding the signing of the oil and gas arrangement with Russia and the sale of NIS . Similar, and slightly hysterical, debates were held in the spring of 2007, on the issue of a possible Russian veto in the UN Security Council on the future status of Kosovo. Those two events - with an entire series of other indicators - clearly testify to the fact that the Serbian public today is very focused on Russia, events related to Russia and the new yet historical Russian-Serbian relations.

Observations on Contemporary Russia

Author(s): Miroslav Jovanović,Alexey Timofeev,Žarko Petrović / Language(s): English Publication Year: 0

The economic crisis Russia now experiences is of a dual nature. It experiences a global crisis, and Russia’s own domestic economic crisis, which was catalyzed by the global one. The model of Russia’s economic development, based on extraction of natural resources, was coming to a logical end. Russia’s inability to keep its economy growing fast was just a matter of time. Although the political crisis and the consequent reformatting of Russia’s political system look inevitable, there will, probably, not be a massive social unrest which will lead to it. According to sociologists it takes about a year to convert job losses and the inability to keep up with habitual life styles into an organized political protest. System’s safety margin by this factor goes well beyond 2009, keeping in mind the essential financial reserves to provide certain social guaranties.

EURASIA SECURITY FRAMEWORK

Author(s): Andrei Zagorski,Andrew Monaghan,Srđan Gligorijević,Žarko Petrović / Language(s): English Publication Year: 0

Two years after Putin’s tough “Munich strategy” was announced, its balance sheet remains extremely ambivalent. Those who believe that the hard ball policy has paid off, point out to the fact that Russia matters again in international politics and that the US and its European allies seek to re-engage Moscow, identify cooperative solutions to the issues of controversy, and ensure Russia’s cooperation on issues of common interest.

Russia’s Role in the Provision of Sustainable Energy Security in South Eastern Europe

Author(s): Igor Tomberg,Pavel K. Baev,András Deák,Konstantin Michajlovič Simonov,Milan Simurdić,Zorana Z. Mihajlović Milanović,Anatoly Pomorcev / Language(s): English Publication Year: 0

2009 – the crisis year – brought about crucial changes in the established and seemingly successful picture of the oil market. The New Year “gas war” between Russia and Ukraine consolidated bad tradition, demonstrating the vulnerability of the present structure of the oil and gas market once again. There were no winners, everyone suffered: the supplier, the transporter and the consumers. Conclusions and assessments of the conflict, and its consequences, are, generally, diametrically opposed. This was reflected in the subsequent actions and statements of the players in the market. It seems generally considered that on the ‘gas front’ Russia is leading a war “against all”. This confrontation is not new; but if earlier it could be considered as “debatable”, now resentment towards the actions and positions of Moscow are reaching a kind of hysteria. Such a political context, alongside some recent events, certainly has an influence on the future of the energy security in Europe, especially considering dramatic changes in the oil and gas markets.

Russian Serbian Cooperation in the Field of Culture

Author(s): Miroslav Jovanović,Goran Miloradović / Language(s): English Publication Year: 0

When we speak today about both present and past Serbian-Russian relations, we usually give priority to politics. However, the history of mutual relations shows that other connections were equally important, such as cultural, artistic, spiritual, religious and ecclesiastical ties between these two peoples (we could also include scientific connections, but it would require too much specific detail in a general overview such as this).
