In the European Union the seismic safety of structures is ensured by Eurocodes and "performance-based design". However, many existing buildings, and even some newly designed, still have some vulnerabilities. Progress-based vision is undermined by the reality of some unexpected disasters

If the potential effects are assessed in terms of exposure, sensitivity, and vulnerability, a GIS methodology, based on statistical indicators and GIS modelling was used to assess the overall vulnerability of the Tisza river basin and define the flood-prone area. Even though specific indicators exhibited high values in some NUTS III units, the overall vulnerability of the regions appears to be low.

Polycentric development is a key instrument for promoting economic competitiveness, social cohesion and environmental sustainability, and its assessment has a particular importance for the European strategies. The paper aims to assess the level of polycentricity of Romania based on a methodology developed by changing the one used in ESPON 1.1.1 by replacing the GDP with the turnover, multimodal accessibility with accessibility, and using a threshold of 30,000 inhabitants instead of 50,000 for the centres of functional urban areas. The results, consisting of country rankings based on size, location, connectivity, and polycentricity, were compared to those of ESPON 1.1.1. Romania ranked fifth in the top from the Polycentricity Index of ESPON countries, with a medium high level of polycentricity.

Demand for concrete, hence for cement, is constantly growing, especially in highly developed countries, which means that alternative binders are urgently required to meet the needs of millions of people, without compromising the CO2 levels of the atmosphere. Although environmental issues are currently not sufficiently convincing to create a sufficiently high demand for the production of geopolymer technology, this is expected to increase with the imposition of rules on carbon dioxide emissions and their effects. Preliminary alkali-activated geopolymer concrete mixtures were developed based on a rigorous trial-and-error process in order to establish the mechanical properties of the geopolymer paving blocks. The aim of this paper is to present results regarding the technology of development and optimisation for the production of geopolymer paving blocks, their mechanical properties and implementation possibilities in accordance with the intended scope of use. The study results indicate that alkali-activated geopolymer paving blocks have excellent mechanical properties, by reference to OPC paving blocks, making them suitable for practical applications.

R. of China with the topic "Evaluation and Investigation of Seismic Risk Reduction Solutions for Buildings, Before and After Earthquakes". The Project "RISKSOLVE" aimed at an exchange of information between experts from Romania and P.R. of China on legal framework for seismic design of buildings, seismic risk reduction and disaster prevention in each country. The study of sites with seismic risk, processing and evaluating the strong motion recordings was associated with the study of earthquake resistance and behaviour of building systems, correlation of damaged buildings patterns, properties and characteristics of materials and seismic site conditions. On the other hand, the design code solutions, as well as adequate retrofitting methods and construction details were evaluated, based on dynamicseismic and static experimental tests on chosen solutions. The counterparts obtained promising results and information, useful to earthquake engineering researchers, in view of achievement of top scientific and technological results and future cooperation Romania-China.

Initially, resilience was perceived as a component of stability (along with resistance, persistence, and variability), and later as a self-standing concept. As the understanding of equilibrium moves from homeostasis to homeoerhesis and practically to the carrying capacity, and stability finds different interpretations, ranging from constancy to dynamic equilibrium, the dynamics of ecological systems is modeled using adaptive instead of succession cycles. The new model is currently applied to other sciences, and also adapted to the man-dominated systems, including the urban ones. In this case, the understanding of resilience is even more divided among specialists, with particular interpretations resulting from partial or sectoral viewpoints. The analysis shows that more research is not a promising solution, but conceptual refinement is required instead.

Furthermore, impressive military infrastructures had been built on both sides, which now lie abandoned.

This infrastructure includes at present, among other research facilities, a strong-motion network of 64 permanent seismic stations, to which other temporary stations are added for various short-term vibration monitoring projects. Since its establishment in 1967, the seismic network has played an essential role in recording the earthquakes that affect Romania. Today, the seismic stations are distributed all over the country, according to its characteristic seismicity patterns. Most of them use state-of-the-art recording and communication equipment, being permanently connected online to the Data Center in Bucharest. The management of the network implies conducting a complex set of activities, centered on the recording, proce...

This paper presents the capacity of sheep wool heat-insulating mattresses to simultaneously provide these needs, cumulatively analyzing efficiency indicators for thermal insulation and indicators of improving air quality. Thus, the values obtained for the coefficient of thermal conductivity, and its resistance to heat transfer, demonstrate the suitability of their use for thermal insulation. The results of the permeability to water vapor characteristics on the sorption/desorption of water, air, demonstrate the ability to control the humidity of the indoor air and the results on the reduction of the concentration of formaldehyde, demonstrating their contribution to the growth of the quality of the air, and to reduce the risk of disease in the population.

In order to move into a more sustainable economic system, a recently more frequently discussed approach for overcoming the current linearity of product lifecycles is the concept of circular economy (CE). The transition to a more circular economy, where the value of products, materials and resources is maintained and circulated (by recycling activities) in the economy for as long as possible, is an essential contribution to the EU's efforts to develop a sustainable, low carbon, resource efficient and competitive economy. In this context, ecological solutions consisting of materials which helps carbon sequestration and necessitates small amounts of energy for production are becoming increasingly popular from buildings construction point of view, namely: the raw material is cheap and in large quantities; have low thermal conductivity; are from a renewable source. The paper presents an analysis of some innovative thermal insulating products made from renewable or recycled resources (recycled plastics, low quality wool, straw, cellulose), their thermal conductivities over a temperature interval and acoustics coefficients (αs, α w), the purpose being to inform the market in order to increase the present level of technical knowledge and to facilitate the implementation of high energy efficiency buildings with products from recycled materials or using industrial by-products.

These countries manage seismic networks that contribute to the European Integrated Data Archive node in the framework of the Observatories and Research Facilities for European Seismology, which represents a collaborative effort in coordinating observational seismology across the European region through the collection, archiving, and dissemination of seismic waveform data, metadata, and related products. All of the aforementioned countries share a common threat: strong earthquakes occurring in the Vrancea area located in central-eastern Romania at intermediate depths (usually in the 60–180 km interval). Events such as the ones on 10 November 1940 and 4 March 1977 generated high damage in Romania, northern Bulgaria, and Moldova. In addition to Vrancea, crustal earthquakes in areas such as Shabla or Dulovo can lead to ...

The outstanding natural diversity, including ecosystems, habitats and species situated at the top of European and International conservation lists, is mixed with an equally rich and important cultural (ethnic and religious) diversity of the human communities inhabiting the area. According to the guidelines of the Man and the Biosphere Programme of UNESCO, the biosphere reserves including human settlements should be managed such that they could constitute an example for what sustainable development means. Starting from the spatial dimension added to the traditional socioeconomic, ecological and cultural pillars of sustainable development, the paper examines planning, architecture, seismic, construction and energy-related criteria that could substantiate a sustainable development model applicable to the Danube Delta, and counter the effects of clime change in the area. The results suggest that the traditional practices of the inhabitants could offer sustainable solutions and help preserving the natural and cultural diversity of the region.

Investigations were made of how the structure, hardness, and depth of the hardened layer depend on the processing regime and on the initial temperature of the steel in the case of alloying with boron carbide and with Cr+C and Cr+B4C mixtures. The greatest hardening was achieved by alloying with a mixture of Cr and B4C powders. This was due to a higher volume fraction of the second phase in the layer and to the precipitation of chromium carboborides. Several types of alloying utilizing Cr+B4C and containing additional agents and modifiers were developed on the basis of the data obtained.

CRISALIDE project (City Replicable and Integrated Smart Actions Leading Innovation to Develop Urban Economies) started in October 2018 and was one of the very few projects financed between E.U. and Russian Federation through the ERA NET RUS PLUS (ENRP) program. It was also the only financed project in ENRP dealing with urban planning topics in this current E.U. programming period (2013-2020). The project became possible due to the rising requests for innovations in urban life resulted in a noticeable shift in a political discourse towards the innovative ICT led economy, the new digital technologies, and the smart city policy in Russia. Though new initiatives seem too focused on technological solutions and lack a comprehensive understanding of smart development, they provoke the appearance of public discussions of the mentioned issues in cities,...

The first method was to determine the compressive strength of cement mortars, partially substituted by glass powder, silica fume, ash and clay. The second method was determining the chemical composition of the powder with fluorescence X-ray, XRF type. The third method, was based on fragments of mortar studied and subjected to microscopic observations – SEM determination (scanning electron microscopy) to investigate the microstructure of the raw material.
