LA VALORIZZAZIONE ENERGETICA DELLA BIOMASSA RESIDUALE IN IMPIANTI DI PICCOLA TAGLIA: SVILUPPO DI UN PROTOTIPO INNOVATIVO DI GASSIFICATORE
Full text linkTo prevent the most severe impacts of climate change the European Union has set itself targets for reducing greenhouse gas emissions produced by human activities. The mission is to transform Europe into a highly energy-efficient, low carbon economy, by reducing emissions from the main sectors (power generation, industry, transport, buildings and construction, as well as agriculture) in the order of 40% by 2030 and 60% by 2040.
Energy production from renewable sources is one of the main pillars in the European ("Europe 2020", the new climate-energy package for 2030 and "Energy Roadmap 2050"), national (the "Strategy National Energy Strategy "(SEN)," National Action Plan for Renewable Energy "(PAN) and" Action Plan for Energy Efficiency "(PAEE)) and regional ("Burden Sharing "energy Plan and the Region of Veneto) climate and energy policy.
In rural areas, priority could be given in Italy to energy from sustainable biomass resources due to their concomitant positive effects in terms of sustainable forest and waste-management, with due regard to local/regional environmental conditions and constraints.
My scientific research aim at developing an innovative technological solution for small farm business that leads to improve their competitiveness through the reduction of fixed costs associated to waste disposal and energy supply and thorough an additional income resulting from feed-in tariff mechanism.
For this reason we create a partnership between the Department of Industrial Engineering (DII) and the Department of Industrial Engineering and Management Systems (DTG) and the company farm "Pronto Giardino snc". The project, called "VERAGRI - Renewable Energy - "Generatore Tristadio a scarti verde per aziende agricole", was funded under Measure 124 (Cooperation for development of new products, processes and technologies in the agriculture, food and forestry - action challenges - EC Reg 1698/2005 - PSR Veneto - DGR 745 of 15/03/2010). The project has concerned the study, the evaluation and the implementation of an innovative prototype of gasification system for energy self- sufficiency and environmental impact reduction of the company farm through the enhancement of green waste resulting from the activities of pruning and mowing.
The Phd thesis has been divided into a first part on the European, national and regional framework about promotion of renewable energy sources evaluating the potential related to the exploitation of energy from residual biomass. The second part describes in detail the stages of development and construction of the prototype, highlighting, for each of those, the objectives and the results obtained.
Finally, the third part analyzes the cost-effectiveness related to the realization of cogeneration system fueled by residual biomass.
The Chapter 2 - "Energy Policy and development scenarios" analyzes the European and National strategy in order to promote resource efficiency and renewable energies. It examines in depth the proposed tools to achieve the expected results for 2020, 2030, and 2050. These targets impact on regional policy as a result of the D.M. March 15, 2012 (called "Burden Sharing") , which divides at the regional level the national target of 17 % of consumption of renewable energy sources on gross final energy consumption. The chapter ends with the description of the methodology used to elaborate the trend scenario, energy efficiency scenario and renewable energy scenario. These scenarios were developed for Veneto Region for the purposes of the Regional Energy Plan; a tool to plan energy policy and identify the actions to achieve the goals set in the Burden Sharing.
The Chapter 3 - "Energy potential of residual biomass" analyzes the biomass energy potential at regional and provincial level, focusing on residual ligneous biomass coming from forestry, agriculture and urban waste. For each sector was estimated provincial and regional availability of residual biomass and quantified the potential energy resulting from their exploitation both in terms of primary energy produced and in terms of percentage of gross final consumption covered.
The Chapter 4 - "The project VERAGRI - Development of a prototype of gasifier fueled by residual biomass" deals in detail the stages of the development of the micro-CHP prototype. The project activities have concerned the analysis of the physical-chemical properties of biomass samples resulting from the activities of pruning, the choice of the process of energy conversion and the design and construction of the gasification reactor and of the auxiliary systems (the filtration system, the pre-treatment system, the electricity and thermal energy generator, the cooling system and the management system). For each element of the system have been highlighted the problems and technical solutions envisaged. In the final part of the chapter is presented the economic scheme of the project VERAGRI and an analysis of the legislation regarding the future commercialization.
Finally, Chapter 5 "Economic Analysis and Renewable Incentives" analyzes in detail the financial aspects relating to investments incurred for the installation of the prototype. Once verified compliance with the requirements for access to the incentive system provided by D.M. July 6, 2012, it analyzed the payback time, the cash flows and the Net Present Value (NPV) for the micro-CHP system, comparing them with products currently available on the market. The economic analysis has also allowed to highlight some of the factors essential for a profitable investment
The energy and environmental plan of a province in the North East of Italy
No full textThis paper focus on Local Authorities and their key role in promoting sustainable development patterns. Energy Action Plan is the political-administrative tool to define the framework in which the different proposed actions are integrated.
It describes a methodological approach in a fragmented context, such as Italy, characterized by small towns with less than 10’000 inhabitants that often lack of technical skills. The paper focus on Provinces and how they provide a platform for coordinating and boosting local actions. This paper describes how Local Energy Agency created a pool of experts coordinated by the university to develop a roadmap of strategies to achieve their goals in a territory of 900’000 inhabitants and 104 city councils.
In this paper the methodology for the definition of the current energy consumption defined on the base of statistical analysis is shown; the energy consumption has been divided into sectors and energy vectors. Afterwards, based on identified growth trends, energy saving potential and enhance renewable energy have been evaluated, identifying objectives and suggesting alternatives to achieve different scenarios.
Finally the paper focuses on the way in which the plan is elaborated in order to provide a proper communication for promoting actions to local stakeholders
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
