Regional Development Perspectives of Production and Utilisation Renewable Fuels in Hungary
No full textThe main aim of the present article is to
highlight the regional development perspectives of production
and utilization renewable energy fuels in Hungary. Due to our
model it is possible to examine the relations between the
terms mentioned above. In the model area the most significant
elements are highlighted in relation to renewable fuels and
sustainability. It implies the importance of holistic approach
that is crucial in these investigations. Only marginal attention
is paid to the regional impacts of renewable fuels. Taking
every result into account, this methodologically complex
subject is possible to examine from the point of sustainability.
Sustainable development can not be grasped easily, but the
production and utilization of renewable fuels can be one of
the tools to further the practical implementation of regional
sustainability

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
SUSTAINABLE COUNTRYSIDE AND COMPETITIVENESS
No full textSustainability, which is a way of thinking, life, production and consumption, covers all dimensions of human existence, its relation to natural resources, the economy and society. Sustainability can be the solution, beside research and development processes, to global problems like globalising economy and market competition, global warming, poverty and famine. United Nations’ actions from Rio to Johannesburg and EU decisions seem to underpin this. Well intentioned efforts up to the present have been made on global level with few results. Therefore it is necessary to implement sustainability on regional and local sub-regional, company level. Sustainability is getting into the centre of expectations and actions. It is very likely that only regions and subregions recognising the importance of sustainability in time, will be successful and competitive as a result of this advantage. Settlements neglecting sustainability will not be able to keep their inhabitants, the countryside around them will not be able to produce enough products meeting food safety standards, and will exhaust its natural resources fairly quickly. The competitiveness of a region is largely determined by the state and development pattern of its rural areas and settlements. Therefore research has been focused on sustainable countryside and its important elements, sustainable (liveable) settlements. During our investigations we implemented a new indicator and index number set that reflects all dimensions of sustainability, the present situation, and supports the bottom up decision making process of local governments and NGOs in order to promote development. These investigations highlighted the facts that potential competitiveness of a region can only be based on sustainable settlements, subregions and it is essential to eliminate deficiencies that restrain present and future development. XXXXXXXXXXXXXXXXXXXXXXXXXX A fenntarthatóság, amely szemlélet-, gondolkodás-, élet-, termelési-, valamint fogyasztási mód felöleli az emberi létezés valamennyi dimenzióját, a természeti erÅ‘forrásokhoz való viszonyát, a gazdaságot és a társadalmat. A globális kihÃvá-sok leküzdésében – mint például a globalizálódó gazdaság és piaci verseny, a globális felmelegedés, a szegénység és éhezés leküzdése –, a kutatási – innovációs folyamatok mellett a fenntarthatóság jelentheti a megoldást. Ezt megerÅ‘sÃtik az ENSZ világrendezvényei Riótól – Johannesburgig, valamint az EU határozatai. Az eddigi jó szándékú próbálkozások globális szinten mozogtak, vajmi kevés eredménnyel. Ezért szükséges a fenntarthatóság regionális és lokális – kistérségi, települési, vállalkozási – szintjein kezdeményezni a megoldást. A fenntarthatóság egyre inkább az elvárások és cselekvések középpontjába kerül, várható, hogy csak azok a régiók, kistérségek, helyi szintek lehetnek eredményesek, versenyké-pesek melyek idÅ‘ben felismerték a fenntarthatóság érvényesÃtésének szükséges-ségét, s ezzel helyzeti elÅ‘nyre tesznek szert. Ugyanis a fenntarthatóságot mellÅ‘zÅ‘ települések nem tudják megtartani lakosaikat, s a vidék nem képes megfelelÅ‘ minÅ‘ségű, az élelmiszerbiztonsági igényeknek megfelelÅ‘ termékeket kibocsátani, s nem hosszabb távon felélik természeti erÅ‘forrásaikat. A régiók versenyesélyét sokban meghatározzák a régión belüli vidéki térségek és települések helyzete, s fejlÅ‘dése. Ezért a kutatások a fenntartható vidék és ennek lényegi elemére a fenntartható, vagyis élhetÅ‘ településre irányultak. A vizsgálatok erre a célra egy újszerű indikátor és mutatószámrendszert alkalmaztak, amely tükrözte a fenn-tarthatóság dimenzióit, az adott helyzetet, s megalapozzák az alulról épÃtkezÅ‘ te-lepülési és civil szervezeti önkormányzatok a fejlesztés lehetÅ‘ségeit. A vizsgálatok hangsúlyozzák, hogy a fenntartható településekre-kistérségekre épülhet a régió versenyesélye, s mindebben különösen fontos szerepe van a jelent és jövÅ‘t korlá-tozó „hiányok†felszámolásának.Community/Rural/Urban Development, Environmental Economics and Policy, Public Economics, sustainability on regional level, settlements, investigations - fenntarthatóság regionális szintje, települések, beruházások,

No full textVisualizing electromagnetic fields at the nanoscale by single molecule localization
No full textCoupling of light to the free electrons at metallic surfaces allows the confinement of electric fields to subwavelength dimensions, far below the optical diffraction limit. While this is routinely used to manipulate light at the nanoscale,1 in electro-optic devices2 and enhanced spectroscopic techniques,3?6 no characterization technique for imaging the underlying nanoscopic electromagnetic fields exists, which does not perturb the field4,7 or employ complex electron beam imaging.8,9 Here, we demonstrate the direct visualization of electromagnetic fields on patterned metallic substrates at nanometer resolution, exploiting a strong “autonomous” fluorescence-blinking behavior of single molecules within the confined fields allowing their localization. Use of DNA-constructs for precise positioning of fluorescence dyes on the surface induces this distance-dependent autonomous blinking thus completely obviating the need for exogenous agents or switching methods. Mapping such electromagnetic field distributions at nanometer resolution aids the rational design of nanometals for diverse photonic applications
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
