Sociālās un ekonomiskās ietekmes ezeru attīrīšanā un labiekārtošanā.
2015
Bakalaura darba „Sociālās un ekonomiskās ietekmes ezeru attīrīšanā un labiekārtošanā” mērķis ir izprast ezeru un to ekosistēmu nozīmīgumu, regulējošās un atbalsta funkcijas, izanalizēt sociālos un ekonomiskos ieguvumus veicot ieguldījumus ezera infrastruktūras un tur mītošo zivju sugu pavairošanas projektos. Bakalaura darba uzdevumos ietilpst ekosistēmu darbības principu apskate, šā brīža makšķerēšanas nozares un ezeru stāvokļa un to problēmu apzināšanās, kā arī ārzemēs veikto pētniecisko darbu analīze un aptaujas rezultātu analizēšana. Lai spētu sniegt ieteikumus Smiltenes ezeru attīrīšanas un labiekārtošanas plāna projekta realizēšanai, tiek izpētīts Katvaru ezera apsaimniekošanas modelis…

The green factor in European manufacturing: a case study of the Spanish ceramic tile industry
2014
This paper analyses how environmental issues have affected and are continuing to affect the evolution of European manufacturing industries based on the example of the Spanish Ceramic Tile Industry (SCTI).1 The Ceramic Tile Industry (CTI)2 in Europe became very competitive and innovative in the early 1990s, with the Italian and the Spanish sectors, which are cluster-based, becoming world leaders. However, since 2008, this leadership position is being eroded. We provide an in depth analysis of the SCTI focusing on the influence of new European environmental regulations. The CTI has a major impact on the environment and has been the focus of environmental regulations. We also consider the inno…
Knowledge transfer and university-business relations: Current trends in research
2017
Purpose: To identify the current research trends regarding knowledge transfer and the university-business relationships during the period 2013-2016 in the journals indexed in ISI Web of Knowledge. Design/methodology: In order to fulfill the research objective, a bibliographic search was conducted using the Pro-KnowC (Knowledge Development Process-Constructivist) tool, developed by LabMCDA (Laboratory of Multicriteria Methodologies to Support Constructivist Decision-Making). Findings: As a result, a total of 122 articles were identified, classified into 4 separate lines of research, in which the most discussed topic was the economic impact of university-business relations, appearing in a tot…
Volcanogenic particulates and gases from Etna volcano (Italy)
2014
Volcanic emissions represent one of the most relevant natural sources of trace elements to the troposphere. Due to their potential toxicity they may have important environmental impacts from the local to the global scale and they can severely affect the atmospheric and terrestrial environment also at timescales ranging from a few to million years. Etna volcano is known as one of the largest global contributors of magmatic gases (CO2, SO2, and halogens) and particulate matter, including some toxic trace elements. The aim of this study was to characterize the chemical composition and the mineralogical features of the volcanogenic aerosol passively emitted from Mt. Etna. Nine samples were coll…
Energy and environmental assessment of residual bio-wastes management strategies
2021
Abstract This paper assesses the potential energy and environmental impacts of an anaerobic digester coupled with a combined heat and power plant powered with bio-wastes from the agri-food sector. The analysis is carried out through the Life Cycle Assessment methodology following a “cradle-to-grave” approach and is based mostly on primary data. The anaerobic digester - combined heat and power plant is analysed considering a twofold perspective: one more energy – oriented where the main function of the system is to generate renewable electricity and a waste – oriented one in which the main function is treating bio-wastes. In addition, the environmental indirect effects related to potential c…
A Tool for Energy Management and Cost Assessment of Pumps in Waste Water Treatment Plants
2017
Waste Water Treatment Plants (WWTPs) are generally considered energy intensive. Substantial energy saving potentials have been identified by several authors. Pumps consume around 12% of the overall WWTP energy consumption. In this paper we propose a methodology that uses the sensors commonly installed in WWTPs, such as volume and energy sensors, to perform energy benchmarking on pumps. The relationship between energy efficiency and flow rate is used to detect specific problems, and potential solutions are proposed, taking into consideration economical and environmental criteria (cost of externalities in energy production). The methodology integrates energy benchmarking, data-mining, and eco…
Torrefied versus conventional pellet production – A comparative study on energy and emission balance based on pilot-plant data and EU sustainability …
2015
Abstract Torrefaction is an emerging technology which enables greater co-firing rates of biomass with coal. To date however there has been a lack of real production data from pilot-scale torrefaction plants. Without such data any environmental benefits of torrefied pellet production are difficult to quantify. In this study data on consumable inputs from a semi-industrial torrefaction plant and the physical properties of produced pellets are used to analyse energy input and air emissions of torrefied pellet production and product transport. EU sustainability criteria are used to compare CO2-equivalent emissions from torrefied and conventional pellet production starting from harvesting of log…
Role of modeling uncertainty in the estimation of climate and socioeconomic impact on river water quality. J. of Water Resources Planning and Managem…
2012
Climate is one of the most important factors leading to changes in the hydrologic and environmental characteristics of river basins. When considering water quality, the natural factors should be weighed against anthropogenic factors (such as urbanization, increased population, and higher water demand) that may increase or decrease the effect of climatic modifications. Any prediction of future climatic and anthropogenic scenarios is affected by uncertainty and the modelling tools that are used for evaluating their impact on receiving water bodies. The present paper is aimed at investigating the complexity of such analyses and the uncertainty related to future impact predictions based on limi…
Environmental Impact Assessment (EIA) of Wave Energy Converter (WEC)
2015
The Environmental Impact Assessment (EIA) is an environmental management instrument implemented worldwide. In the last years the development of Wave Energy Converter (WEC) influenced environmental research to quantify impacts on marine life. In this paper we present a case study of EIA: a real application and study of device installed in Tirren Sea (near Castellammare — Sicily).
