The particle spectrum of the Tricritical Ising Model with spin reversal symmetric perturbations
We analyze the evolution of the particle spectrum of the Tricritical Ising
Model by varying the couplings of the energy and vacancy density fields. The
particle content changes from the spectrum of a supersymmetric theory (either
of an exact or a spontaneously broken supersymmetric theory) to the spectrum of
seven particles related to the underlying E_7 structure. In the low temperature
phase some of these excitations are topologically charged particles that are
stable under an arbitrary variation of the parameters. The high and low
temperature phases of the model are related by duality. In some regions of the
two couplings there are also present false vacua and sequences of bound states.
In order to study the non-integrable features of this model we employ the Form
Factor Perturbation Theory and the Truncated Conformal Space Approach.Comment: 34 pages, 14 figures, text misprints correcte
Healthcare values and potential uses of the new Hungarian apple varieties on the basis on fruit analysis
Biological active compounds and valuable characteristics of some apple varieties and candidates were measured in our trials. Fruits of ’Rosmerta’, ’Hesztia’, ’Cordelia’ and ’Artemisz’ are recommended to enrich the Hungarian assortments for fresh consumption and choice of new tastes. Based on examined parameters it can be assumed that novel Hungarian resistant varieties are suitable for juice and fruit concentrate production, and due to high pectin content of their remaining pomace these varieties can be raw material of pectin production as well as they are also suitable for jam production mixed with other fruit species. Furthermore, functional food industrial product having high quality can be produced by using novel resistant varieties because of their high pectin and polyphenol content. Beside of their high market value their suitability for growing among orchard conditions is confi rmed by lower costs of production because of less plant protection treatments

Experimental determination of the He(,)Be reaction cross section above the Be proton separation threshold
The He(,)Be reaction plays a major role both in the
BBN producing the majority of the primordial Li, and in the pp-chain, where
it is the branching point. As a few-nucleon system, this reaction is often used
to validate ab-initio theoretical calculations and/or test R-matrix theory and
code implementations. For the latter, experimental data in an extended energy
range is of crucial importance to test the fit and extrapolation capabilities
of the different codes. The He(,)Be reaction cross
section has been measured by several groups up to the first resonance
( MeV) in the reaction. However, only one dataset exists
above the Be proton separation threshold measured in a narrow energy range
( MeV). In this work we extend the available experimental
capture cross section database to the energy range of known Be levels. The
activation method was used. The experiment was performed using a thin-window
gas cell with two high-purity Al foils as entrance and exit windows. The
activity of the Be nuclei implanted in the exit/catcher foil was measured
by detecting the yield of the emitted ~rays using shielded high-purity
germanium detectors. New experimental He(,)Be reaction
cross section data were obtained for the first time in the
MeV energy region. The new dataset with about 0.2 MeV step covers the energy
range of known levels and particle separation thresholds. No prominent
structures are observer around the Be levels. The reaction cross section is
slowly increasing with increasing energy. Above the Li threshold, a
decrease starts in the cross section trend. The overall structure of the cross
section suggest a broad resonance peaking around MeV Be
excitation energy, with a width of 8 MeV.Comment: Accepted for publication in PR
Persistence with statin therapy in Hungary
Introduction: Persistence with lipid-lowering drug therapy by cardiovascular patients in Hungary has not been studied previously. This study was designed to determine the rate with which Hungarian patients with hyperlipidemia persist in taking lipid-lowering agents, and to compare this with rates reported from other countries.
Material and methods: This was a retrospective study that utilized data from the Institutional Database of the National Health Insurance Fund to analyze persistence rates with statins and ezetimibe. The study included data for patients who started lipid-lowering therapy between January 1, 2007, and March 31, 2009. Variables included type of lipid-lowering therapy, year of therapy start, and patient age. Main outcome measures were medians of persistence in months, percentages of patients persisting in therapy for 6 and 12 months, and Kaplan-Meier persistence plots.
Results: The percentage of patients who persisted with overall statin therapy was 46% after 1 month, 40.3% after 2 months, 27% after 6 months, and 20.1% after 12 months. Persistence was slightly greater for statin therapy started during 2008 than during 2007. Older patients were more persistent with therapy than younger patients. Persistence with the combination of ezetimibe-statin therapy was greater than with statin or ezetimibe monotherapy.
Conclusions: Persistence with statin therapy by patients in Hungary was low compared with other countries. Low persistence may have negated potential clinical benefits of long-term statin therapy

Composition and sensory properties of sour cherry cultivars
Fruits of different sour cherry varieties cultivated, in 2008 and 2009, under organic farming and integrated cultivation conditions were analysed for their quality attributes, antioxidant activity and subjected to sensory evaluation.. Average size, weight, soluble solids, titratable acidity, total polyphenols, free radical scavenging capacity expressed as Trolox equivalent (TEAC), copper and zinc were determined in freshly harvested fruits. The obtained results indicated that, the principal component analysis can separate and distinguish the seasons of fruit production. The farming system seemed to have slight effect on quality the fruit as compared to varietal factors (genotypes). However, the total polyphenol content was uniformly less in 2009. Total polyphenols and free radical scavenging activity were significantly higher in Bosnian type sour cherries, and outstanding in Amarelle type cultivar ‘Pipacs’. There was no statistically significant difference between the sensory properties of cultivars tested by panels, except the case of ‘Pipacs’. The organolaptic investigation showed marked preference to the fruits of Eva and Petri cultivars
