The present paper deals with the semantic features of three Hungarian neologisms (becéloz, betámad, bevállal), and analyzes their semantic structures with the help of the Conceptual Integration Theory (Blending Theory). The words analyzed are verbs that have been used with the prefix be in recent years, although they are wellestablished with other prefix(es). As be is one of the oldest Hungarian prefixes, it has likely gained new function(s) in these cases. To substantiate this claim, data was gathered from two questionnaires (in 2010 and in 2014), and informants' answers concerning meaning and style were analyzed. These data can help the survey in other fields too: firstly, they can help model the processes of understanding (or misunderstanding) of these neologisms, secondly, they can help model the semantic structures of the verbs within the framework of Blending Theory. Thirdly, these data can help indicate language use at a given point in time, from a synchronic viewpoint. [ABSTRACT FROM AUTHOR]

In this paper, an optimization model for biogas power plant feedstock mixture with respect to feedstock and transportation costs using a differential evolution algorithm (DEA) is presented. A mathematical model and an optimization problem are presented. The proposed model introduces an optimal mixture of different feedstock combinations in a biogas power plant and informs about the maximal transportation distance for each feedstock before being unprofitable. In the case study, the proposed model is applied to five most commonly used feedstock in biogas power plants in Croatia and Hungary. The research is performed for a situation when the biogas power plant is not owned by the farm owner but by a third party. An optimization procedure is performed for each scenario with a cost of methane production that does not exceed 0.75 EUR/m3 in 1 MWe biogas power plant. The results show the needed yearly amounts and the maximum transportation distance of each feedstock. [ABSTRACT FROM AUTHOR]

Clarithromycin is a macrolide antibiotic widely used for eradication of Helicobacter pylori infection, and thus resistance to this antibiotic is a major cause of treatment failure. Here, we present the results of a retrospective observational study of clarithromycin resistance (Cla-res) in 4744 H. pylori-infected patients from Central Hungary. We use immunohistochemistry and fluorescence in situ hybridization on fixed gastric tissue samples to determine H. pylori infection and to infer Cla-res status, respectively. We correlate this information with macrolide dispensing data for the same patients (available through a prescription database) and develop a mathematical model of the population dynamics of Cla-res H. pylori infections. Cla-res is found in 5.5% of macrolide-naive patients (primary Cla-res), with no significant sex difference. The model predicts that this primary Cla-res originates from transmission of resistant bacteria in 98.7% of cases, and derives from spontaneous mutations in the other 1.3%. We find an age-dependent preponderance of female patients among secondary (macrolide-exposed) clarithromycin-resistant infections, predominantly associated with prior use of macrolides for non-eradication purposes. Our results shed light into the sources of primary resistant cases, and indicate that the growth rate of Cla-res prevalence would likely decrease if macrolides were no longer used for purposes other than H. pylori eradication. Clarithromycin is a macrolide antibiotic widely used for eradication of Helicobacter pylori infection. Here, Kocsmár et al. study clarithromycin resistance and previous macrolide consumption in 4,744 H. pylori-infected patients, shedding light into the sources of primary resistant cases and the role played by prior consumption of macrolides for non-eradication purposes.

A phenomenological (termohydraulic-neutronic) model is presented in this paper. It allows the description of the temperature fluctuation field propagation in a PWR. In the model it is considered some different kinds of noise sources, but the related to temperature fluctuation has been considered as the dominant one. Possibilities for parameter estimation application of the model are discussed in details. One expression for temperature reactivity coefficient estimation --parameter related to the safe work of the reactor-- has been obtained and commented. The reported results from the model, has been compared with noise measurements performed in 1986-1987 at the second unit of Paks nuclear power plant in Hungary. The good agreements of results validated the developed model. The described method can lye applied to on-line monitoring of this parameter. [ABSTRACT FROM AUTHOR]

The skill of the land surface model HTESSEL is assessed to reproduce evaporation in response to land surface characteristics and atmospheric forcing, both being spatially variable. Evaporation estimates for the 2005 growing season are inferred from satellite observations of the Western part of Hungary and compared to model outcomes. Atmospheric forcings are obtained from a hindcast run with the Regional Climate Model RACMO2. Although HTESSEL slightly underpredicts the seasonal evaporative fraction as compared to satellite estimates, the mean, 10th and 90th percentile of this variable are of the same magnitude as the satellite observations. The initial water as stored in the soil and snow layer does not have a significant effect on the statistical properties of the evaporative fraction. However, the spatial distribution of the initial soil and snow water significantly affects the spatial distribution of the calculated evaporative fraction and the models ability to reproduce evaporation correctly in low precipitation areas in the considered region. HTESSEL performs weaker in dryer areas. In Western Hungary these areas are situated in the Danube valley, which is partly covered by irrigated cropland and which also may be affected by shallow groundwater. Incorporating (lateral) groundwater flow and irrigation, processes that are not included now, may improve HTESSELs ability to predict evaporation correctly. Evaluation of the model skills using other test areas and larger evaluation periods is needed to confirm the results. Based on earlier sensitivity analysis, the effect of a number of modifications to HTESSEL has been assessed. A more physically based reduction function for dry soils has been introduced, the soil depth is made variable and the effect of swallow groundwater included. However, the combined modification does not lead to a significantly improved performance of HTESSEL. [ABSTRACT FROM AUTHOR]

The article presents a diagnostic study regarding the effects of the lateral boundary conditions to the operations of the REMO 5.0 regional climate model (RCM) in Carpathian Basin, Hungary. Researchers have cited the simulation of the REMO 5.0 RCM from 1961 up to 2000. They conducted an assessment on the impact of the lateral boundary conditions in relation to the REMO model's operations. The re-evaluation of the RCM simulation is also noted.
