INVESTIGATION OF CONSUMER ENVIRONMENTAL AWARENESS BY MARKETING RESEARCH METHODS - METHODOLOGICAL CONSIDERATIONS

In the present article we investigate the demand side of the market from the aspect of moving toward an environmentally aware society as an idea. What are the motivating factors of purchase decisions that regulation in the widest sense can analyse and react on? In what cases can we consider these decisions as environmentally aware? If we would like to gain information about or influence such decisions can we measure the level of environmental awareness, the intensity of motives? If we can measure these, what are the methods we can or should use and what can we expect as a result? These questions are intended to be thought-provoking as the uncertainty is quite high about how to get a non-biased picture of environmental preferences of the customer side

Computational and experimental investigations on a tuneable spatial heterodyne spectrometer

Spatial heterodyne spectrometers (SHS) are interference based instruments for obtaining spectroscopic information in the UV and visible ranges. In this current study we are representing our experimental and computational findings about a tuneable SHS instrument

CARBON MITIGATION IN HUNGARY: CHALLENGES FOR A SUSTAINABLE NATIONAL ENERGY POLICY

While on a world-wide scale Hungary is a key greenhouse gas emitter neither on an absolute nor on a per capita basis, Hungary recognizes the significance of limiting its greenhouse gas emissions. This paper is based on the Hungarian contribution to a two-year, ten-country research effort, funded by UNEP, aimed at developing a state-of-the-art methodology for the understanding of the economics of greenhouse gas abatement. This paper concentrates on the challenges of the implementation of greenhouse gas mitigation measures. While Hungary has an important cost-effective potential for reducing the emission of carbon dioxide by improving energy efficiency, the implementation of this mitigation strategy is a complex and challenging task. The implementation and financing of energy efficiency measures require the concerted targeting of close to 4 million households, and a wide variety of actors, including banks, the industry, government, international and multilateral organisations, and NGOs. Thus, developing an implementation strategy requires a clear understanding of the existing structures, barriers, and experiences to date. This paper provides a strategic framework for the implementation of demand-side energy efficiency, and examines a case study, the tool of energy efficiency labelling and standards, within this framework

A magyar közlekedéspolitika stratégiai környezeti vizsgálata

A stratégiai környezeti vizsgálatok nemzetközi szakirodalmából származó tapasztalatokkal összhangban a közlekedéspolitika vizsgálatához a stratégiai környezeti vizsgálat szélesebb értelmezésének elfogadásával egy általános fenntarthatósági vizsgálat elvégzésére irányuló módszer kidolgozását kezdeményeztük. Ennek keretében a közlekedéspolitika cél- és intézkedési rendszerét elemeztük a célok belső és külső konzisztenciája szempontjából, illetve az egyes célokat összevetettük a fenntarthatóság kritériumaival

Generation of high-order harmonics with tunable photon energy and spectral width using double pulses

This work theoretically investigates high-order harmonic generation in rare gas atoms driven by two temporally delayed ultrashort laser pulses. Apart from their temporal delay, the two pulses are identical. Using a single-atom model of the laser-matter interaction it is shown that the photon energy of the generated harmonics is controllable within the range of one eV -- a bandwidth comparable to the photon energy of the fundamental field -- by varying the time delay between the generating laser pulses. It is also demonstrated that high-order harmonics generated by double pulses have advantageous characteristics, which mimick certain properties of an extreme ultraviolet (XUV) monochromator. With the proposed method, a simpler setup at a much lower cost and comparatively higher spectral yield can be implemented in contrast to other approaches.Comment: 7 pages, 6 figures, after peer-review, corrected typo in author lis

Liquid-cooled modular gas cell system for high-order harmonic generation using high average power laser systems

We present the design and implementation of a new, modular gas target suitable for high-order harmonic generation using high average power lasers. To ensure thermal stability in this high heat load environment, we implement an appropriate liquid cooling system. The system can be used in multiple-cell configurations, allowing us to control the cell length and aperture size. The cell design was optimized with heat and flow simulations for thermal characteristics, vacuum compatibility, and generation medium properties. Finally, the cell system was experimentally validated by conducting high-order harmonic generation measurements using the 100 kHz high average power HR-1 laser system at the Extreme Light Infrastructure Attosecond Light Pulse Source (ELI ALPS) facility. Such a robust, versatile, and stackable gas cell arrangement can easily be adapted to different experimental geometries in both table-top laboratory systems and user-oriented facilities, such as ELI ALPS
