The image of Liszt at the piano has been a favorite with artists. This article examines two paintings: an 1868 painting of Liszt at a Chickering piano by G. P. A. Healy and a 1919 painting of Liszt at a Steinway piano by John C. Johansen. Due to recent publications, the Chickering painting and its story are fairly well-known. In contrast, the Steinway painting is almost unknown. Healy’s portrait (1868) was done in his studio in Rome as Liszt sat playing for him. While Healy had seen Liszt’s Chickering piano, the instrument in his studio was not that piano and, despite the name “Chickering” on the fallboard, the painting does not faithfully convey the details of Liszt’s Chickering. Johansen’s portrait (1919) was done by an artist who had never met Liszt and almost certainly had never seen his Steinway piano. Because of the Chicago connection, this article proposes that Johansen took his inspiration from Healy.

Solvent extraction with TOPO from 6M hydrochloric acid is proposed as a method for the elimination of interfering activities in neutron activation analysis of
biological material for trace elements. By this procedure24Na,42K,32P,82Br, and47Ca are efficiently removed, and a number of trace element activities can be measured by Ge(Li) spectrometry. Chemical yields
are determined by re-activation. Data for Cu, Zn, Mo, and Cd in two biological standards are presented.

The ash behaviour comprises one major obstacle towards the efficient utilization of municipal solid wastes, (MSW), in incineration
plants. The presence of large amounts of inorganic constituents such as alkali and alkali earth metals, chlorine, sulfur and
zinc increase significantly the ash reactivity and lead to severe ash-related problems such as fouling, slagging, corrosion
and erosion during their thermal treatment. In this paper, the melting behaviour of various ash fractions originating from
the incineration of MSW is studied using simultaneous, (DSC/TG), thermal analysis methods. The produced results provide the
basis for improved modelling of the ash behaviour during the incineration of MSW.

This paper introduces a novel idea: the concept of an image transformation. We also introduce the closely related concept of a quasi-homomorphism, and study the properties of these mathematical objects, and give several examples. In particular we investigate iterated systems of image transformations, which we believe give a more realistic approach to the study of so called self-similar structures in nature than what is obtained by iterated function systems.

Thermal analysis is widely used in combustion research for both fundamental and practical investigations. Efficient combustion
of solid fuels in power plants requires understanding of properties and behavior of fuel and ash under a wide range of conditions.
At the Department of Chemical Engineering, Technical University of Denmark, thermogravimetric analysis and differential scanning
calorimetry are applied in order to investigate various aspects of combustion and gasification processes: pyrolysis, char
reactivity and ash melting behavior. This paper shows examples of the application of simultaneous thermal analysis in these
three research areas, and it demonstrates the flexibility of this technique in combustion research.
It is important for Taiwanese policy makers to understand how economic factors affect US tourists’ decision to travel to Taiwan. For the long-run analysis, Johansen’s cointegration test reveals that three cointegration vectors exist among the model variables, indicating a long-run relationship. To conduct a short-run analysis, this paper employs vector auto regression (VAR) to estimate the responses of US tourists in Taiwan to the shocks of changes to personal disposable income, cost of living, and substitute price. The short-run equilibrium adjustment processes are discussed in terms of generalized impulse response. The results show an immediate and significant response of changes in tourist arrivals to their own impacts, changes in the cost of living, and changes in the substitute price. In addition, the price, income, and cross-elasticity of tourism demand are all positive at the beginning of the responses, implying that the tourism products can be attributed to normal and substitute goods.
