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.

To assist international efforts to address major gaps in the availability and accessibility of quality diagnosis and treatment for multi-drug resistant tuberculosis, Médecins Sans Frontières has adapted an approach combining three sets of interlinked strategies: direct provision of medical care, operational research, and public health advocacy. The activities undertaken are reviewed each in turn, with stress on the ways that they impact upon and consolidate each other. In spite of new opportunities, including technologies which significantly improve diagnosis and new, more patient-centred approaches, a much broader international mobilization is needed in order to confront MDR-TB. It is also questionable as to whether existing technologies are successful enough to provide a solid basis for expanded national programs.

The analytical potential of ICP-AES (ICP) and 3He+-activation for the determination of boron was examined. The paper compares ICP-levels of B, obtained from aqueous solutions containing digested plant material, with minimum detectable limits attained in solid matrices that were subjected to prompt gamma-ray analysis using 2 MeV 3He+ ions. The analytically useful gamma-rays originated mainly from (3He,p) and (3He,a) reactions on 11B and Coulomb excitation of 10B. The numerical capabilities of the two techniques for such measurements are discussed, and detailed methodologies and possible difficulties are presented.

The synthetic scope of photo-induced copper-mediated polymerization (photoCMP) in continuous-flow reactors is further explored. A series of monomers, namely, methyl (MA), ethyl (EA), n-butyl (nBA), 2-hydroxyethyl (HEA), and di(ethylene glycol) ethyl ether (DEGA) acrylate are investigated, all showing high livingness (dispersity in the range of 1.1 and linear first order kinetics) in the polymerizations and high conversions within 20-min reaction time. Next to the commonly used solvent (dimethyl sulfoxide [DMSO]), also a water—ethanol mixture was used as greener alternative, without any loss in reaction control. Upscaling the reactor from 2 to 16 mL allows for production of over 200 g of high-definition material (3000 g/mol, 1.1 dispersity) in overnight operation (18 h), demonstrating that the photoprocess can be run under very stable conditions even for extended reaction times. Via coupling of two reactors, direct chain extension of copolymers in a single reaction step is also demonstrated.

The purpose of the present paper is Authors aim was to deliver a compilation of to summarize the Hungarian soil analysies methods and theas well as to present the advisory system for nutrient management advisory system. Both of them are based on several decades of work. We need to should learn from these past experiences of reasonable and good agricultural practices. We can only apply the present and future results of soil science and find out what direction should we develop, if we were aware of the results of the past and we calculate with their governing effects. The majority of our recent methods are based on historical researches and the present current statesituation of our field of scientific fieldce can only be judged and developed further if we knew the former history of the methodological findings. The recent Hungarian soil analysis system provides useful results that can be used very well today, however, the adaptation of the new international methods , learned from the follow-up of the international trends can might provide open new perspectives in for the Hungarian laboratory analyses methodology. TThe subject is extremely timely because there are hea never- met demand for cost and time effective, environmentally friendly soil analysis methods underpin how actual and hot the topic is. nowadays.
