Polysorbates as hydrophilic surface-active structures are food additives with multifunctional competences (emulsifiers, aerating, wetting, foaming, stabilizing agents) and wide HLB range. The present paper has proposed to know the details of the successive transesterification of 2,5 пїЅ diacetyl пїЅ isosorbide (2,5- Ac2ISB) with hydrocarbon chains (Ra) by successive introducing the different amounts of fatty acids obtained from the vegetal lipid fractions isolated from sweet pepper (Capsicum annuum) and chilli pep...

This article is the continuation of the paper published at the conference SGEM in 2016. European product standards generally do not specify the qualitative requirements for individual product characteristics. EN 14695:2010, which deals with the waterproofing of concrete bridge decks, is not an exception. The national standard CSN 736242:2010 sets quality requirements for bitumen sheets. The type of the modification of bitumen coating is not considered in quality requirements of this standard - the mass modified by...

Sulphur is one of the major constituents of lignite. In addition, it is used to measure the negative environmental impacts of this raw material. The presented study included field work and laboratory work. Field work was aimed at collecting coal samples, which were subjected to a series of laboratory tests. In total, about 150 coal samples were collected and used for proximate analysis. In addition, a large database of archival results from mines and scientific literature was collected. Overall, more than 4000 coa...

Aerogels production consists of two main stages: preparation of the gel filled with solvent (alcohols, acetone or hexane) by polymerization or sol-gel process and its supercritical drying. The most energy consuming and complicated from a technical point of view is the drying step [1]. Supercritical drying allows keeping the internal structure by preventing collapse of pores. Supercritical conditions require the use of expensive highpressure apparatus and the process rate is limited by diffusion within the pores of...

Nowadays, trend of stimulating renewable energy production is at the forefront. In this regard, in Slovakia use of renewable energy sources for home electricity and heat generation following European Union support and the project Green to Households is developed considerably. The return on investment on these funds is indeed longer, but we should ta...

Critical literature studies indicated that there had been numerous methods for estimating the value, management models as well as indicators and criteria for the quantitative and qualitative assessment of post-industrial areas. All of them supported post-industrial area management, but neither of them took into account the simultaneous evaluation of economic, social and environmental aspects - especially important for the inclusion of these areas into the socio-economic cycle. Identified gaps in knowledge allowed ...

The assessment of antiseptic solutionsпїЅ efficacy for root canal irrigation in terms of dentinal tubules disinfection is a challenging task. The samples used for this purpose should be standardized according to bacterial counts and the depth of their penetration inside dentinal tubules. However, the samples could be contaminated with bacteria from the surface of dentin during the sample acquisition. The treatment of dentin surface with antiseptic solutions will allow to avoid this contamination and thus to assess...

In the paper there is the analysis of the possibility of the replacement of onerous methods of surface treatment before adhesive bonding. In ecology approach adhesive bonding is not preferred techniques of joying parts. The joints are no separable, but nonetheless have wide range of usage. The adhesive bonding has many assets, like low mass of the joining elements (less material), possibility of joint of different materials, lack of rivets or screws (less weight). But typical preparatory operations in adhesive bon...

Beginning with the statement of the World Conference on Environment and Sustainable Development from Rio de Janeiro (1992), the worldпїЅs countries have started to develop national policies for implementing the concept of sustainable development. The experiences of those years led to a more pragmatic approach of the sustainable development implementing policies. For the first time the European Union and United Nations also realized that without a qualitative and quantitative quantification of the objectives of sus...

Current development in the European Union countries may be considered heterogeneous, even though their economic and social similarities. Each country achieves its economic and social goals with different success rate. It is similarly in relation to the complex value such as sustainable development. Evaluation of sustainability and sustainable development is problematic, because of sustainable development (resp. part of it) can be evaluated using the various indicators. It is, for example, the evaluation of sustain...

Mobility, besides housing and food/drinks, is considered one of the main consumption clusters with high impact on environment that includes pollution (i.e. noise), energy consumption and climate changes. Sustainable mobility therefore should be the task high on the agenda for the municipal development governance and, especially, environmental governance, particularly, keeping sustainability principle - to have the ability of people to travel and supply goods in a way that balances environmental and socio-economic ...

The urgency of sustainable development in the world requires seeking solutions to chronic problems of a number of the past decades. Several of the problems are associated with the environment and food supply. The current food supply system was based on conventional farming, yet such food was produced making negative environmental impacts. Organic primary food production is an alternative to the system, which is based on organic farms, the number of and the land area managed by which have considerably increased. In...

The energetic requalification of the existing buildings stock is a key question in the attainment of the ambitious program regarding the energy efficiency proposed by European Union. There are several measures taken to increase the energy efficiency, both for new buildings and for existing buildings, such us the 20 пїЅ 20 пїЅ 20 EU Policy and the Nearly Zero Energy Buildings goal set by the Energy Performance of Buildings Directive 2010/31/EC, which gives the guidelines to be followed in order to attenuate the ene...

In the context of operationalising sustainable development some progress has been lately achieved in several countries on global level.

Tailings ponds are permeable hydrotechnical structures for retention purposes, specifically designed for safely dumping mining waste from mining operations and for evacuating fluid tailings from mining sites. Tailings ponds are grouped in classes according to their type, intended service life and function at the mining site. Another important criterion of classification is the terrain where the tailings pond is situated. Tailings or mining waste can be defined as the commercially worthless fraction or the waste ma...

Talc-bearing rocks in Kallievo-Murennanvaara deposit are associated with ultramafic rocks of peridotite-picritic series. Serpentinized rocks in the picritic portion of the sequence remained unaffected by talc alteration. Peidotitic komatiites, occurring below picrites which were altered to talc-carbonate rocks by carbon dioxide and then to talc-chloritic rocks under the influence of silica and alumina (the result of granite formation), were productive for soapstone. Kallievo-Murennanvaara soapstone deposit, is loc...

The totality of all that is human-made: technical devices and systems, cities, houses, roads and all that humans have constructed to keep them alive on the planet are called the technosphere. The technosphere though is a relatively new phenomenon is evolving extraordinarily rapidly and its mass has been estimated to approximate to 30 trillion tons. Currently the weight of all that man creates in a year is an order of magnitude greater than the mass of wild living organisms (biomass). Thus, our civilization faces v...

The paper presents deformation of the housing and shaft reinforcement surveyed within the telemetry deformation monitoring system. Research was taken in the Salt Mine Wieliczka Museum, one of the most popular monuments in Poland, placed in 1978 on the original UNESCO list of the World Heritage Sites. Water leaking into Ko?ciuszko shaft posed a serious threat to museum and forced authorities to seal the housing with Jet-grouting method. Due to boreholes which were designed very close to the shaft, the material inje...
