Sustainable development as a challenge for a society and an economy
2017
During the political process leading up to the Earth Summit in Rio de Janeiro in 1992 it was decided that the concept which will be used to coordinate spontaneous development processes will be the concept of sustainable development. Since that time, efforts are made to implement this concept through inclusion in the legal regulations and by modelling the development objectives of societies. This process should be accompanied by: 1) a reflection over a direction in which we should go and 2) a question whether actions, carried out in the spirit of sustainable development, really bring us closer to the realisation of this concept. The proposed paper will develop these last two questions focusi…
Biogas production from the perspective of sustainable development
2020
One of the basic aspects of sustainable development strategy involves investments in green technologies, including energy production from renewable sources. Biomass, special organic waste which belongs to “green sources” of energy can be used in the methane fermentation process of biogas production to generate heat and electricity.Biogas power plants have functioned in the Polish energy industry for many years now. On the basis of the data available from Central Statistical Office, in 2014 the ratio of biogas accounted for 7.6% of the structure of primary energy derived from renewable sources in the EU and 2.6% in Poland. An important consideration related to the production of biogas is ass…

Untargeted metabolomics of rind essential oils allowed to differentiate two closely related clementine varieties
2021
[EN] Chemical characterization of clementine varieties (Citrus clementina Hort. ex Tan.) essential oils (EO) can lead to variety identification and valorization of their potential use in food and aroma industries. The goal of this study was the chemometric discrimination between two very closely related and morphologically identical clementine varieties, Clemenules (NL) and Clemenpons (PO), based on their rind EO, to identify the differential volatile organic compounds (VOCs) and to determine their antioxidant capacity. EO rind volatile profile was determined by gas chromatography coupled to mass spectrometry in Citrus fruit at different ripening stages grown two independent years in two di…
Smart Cities and a Stochastic Frontier Analysis: A Comparison among European Cities
2013
The level of interest in smart cities is growing, and the recent literature on this topic (Holland, 2008; Caragliu et al., 2009, Nijkamp et al., 2011 and Lombardi et al., 2012) identifies a number of factors that characterise a city as smart, such as economic development, environment, human capital, culture and leisure, and e-governance. Thus, the smartness concept is strictly linked to urban efficiency in a multifaceted way. A seminal research for European policy conducted by Giffinger et al. (2007) defines a smart city on the basis of several intangible indicators, such as a smart economy, smart mobility, smart environment, smart people, smart living, and smart governance. These authors’ …
BENCHMARKING FOR A SUSTAINABLE DEVELOPMENT
2015
Benchmarking can represent a rich source of inspiration for creative managers and employees who want to eliminate the mistakes of the past and to find new ways that lead to performance. After a research made from secondary sources, we proposed a new type of benchmarking, designed especially for a sustainable development: the "green-benchmarking". For its applying, a new evaluation index system is required.
Towards a sustainable well-being
2013
Given the need of a new economic paradigm for the achievement of a world of sustainable wellbeing, this paper presents the main findings from the literature on sustainable well-being. We try to identify a few approaches of measurement, highlighting strengths and weaknesses. We analyzed Romania's position in the global context in terms of happiness index. Are sustainable well-being indicators a good guide for policy-making? Also, the paper discusses the role of education in ensuring the sustainable well-being.
THE ANALYSIS OF THE HEAVY METALS IN THE CORN AGRICULTURAL ECOSYSTEM IN THE AXENTE SEVER-COPSA MICA AREA (SIBIU COUNTY)
2013
The invertebrates constitute important indicators in the appreciation of the soil. A first step in this respect is constituted by the analysis of the heavy metals in the corn fields in the Axente Sever and Copsa Micaƒ Area. Methods of researching: collecting the samples in the soil by using the agricultural drill; the determination of the heavy metals by spectroscopy of atomic absorption, using the spectrometer of atomic absorption ContrAA 700. As a result of the researches the average concentration of lead and cadmium in the soil of the agricultural ecosystems from the studied area is still high.
Panorámica de la problemática medioambiental en el mundo y en España
2008
As energy resources become scarce and pollution increases, fundamental and often irreversible changes are affecting our global ecosystem, and these changes are already having an influence on countries’ potential for economic growth and development. In this article we examine the principal environmental problems worldwide and how such problems are affected by inequality between countries. In Spain’s case, the basic problems are greenhouse gas emissions, problems relating to water management and issues concerning territory and biodiversity. We also call for the application of economic funding mechanisms to implement environmental policies.
