Folyóiratunk legfrissebb lapszáma olyan előadások tanulmánnyá bővített változatát tartalmazza, melyek eredetileg a Biopoétika a 20–21. századi magyar prózában című, 2022. szeptember 22–23án Debrecenben megtartott konferencián hangoztak el. Az írások célja, hogy feltérképezzék a modern magyar próza biopoétikai tendenciáit: azaz, egy új keletű szóalkotással élve, bioepikaként olvassák az elmúlt közel száz év néhány meghatározó alkotását.

Purpose - The purpose of this paper is to examine the stability and the parameters affecting the stability of vitamin C in beer, wine and orange juice.Design methodology approach - In this study, a high performance liquid chromatography method was applied for reliable determination of ascorbic acid in these beverages. Three different types of beer, a wine and orange juice sample were spiked with ascorbic acid using different concentrations and pH values. The samples were stored at 4oC, but in some cases 20oC was also used as storage temperature. The joint effect of vitamin C and E was also examined.Findings - The results demonstrated that vitamin C was stable only in orange juice at the original pH values. Under pH=4, beer was also a good matrix for vitamin C addition, but only at low storage temperature (4oC). Vitamin E addition increased the stability of ascorbic acid (p<0.05) even at room temperature.Practical implications - These findings could have significant implications to the beer industry. This study shows that vitamin C can be stable in beer during the shelf life of this product using appropriate pH and storage temperature.Originality value - The paper shows that the addition of an antioxidant vitamin is good from the point of view of the consumer's health, and it can improve the shelf life of the food because of its antioxidant activity.

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography–mass spectrometry (GC–MS) was used to analyse microbial volatile organic compounds (MVOCs) of mushroom disease-related microorganisms. Mycogone perniciosa , Lecanicillum fungicola var. fungicola , and Trichoderma aggressivum f. europaeum species, which are typically harmful in mushroom cultivation, were examined, and Agaricus bisporus (bisporic button mushroom) was also examined as a control. For internal standard, a mixture of alkanes was used; these were introduced as the memory effect of primed septa in the vial seal. Several different marker compounds were found in each sample, which enabled us to distinguish the different moulds and the mushroom mycelium from each other. Monitoring of marker compounds enabled us to investigate the behaviour of moulds. The records of the temporal pattern changes were used to produce partial least squares regression (PLS-R) models that enabled determination of the exact time of contamination (the infection time of the media). Using these evaluation techniques, the presence of mushroom disease-related fungi can be easily detected and monitored via their emitted MVOCs.

The story of Andrea Tompa’s novel takes place in Transylvania in the first decades of the 20th century. In the first half of the novel both protagonists are medical students, in the second half they are practicing doctors. rough using them as firstperson narrators, the writer had the opportunity to use many of the discourses of medicine. This article analyses how they are implemented into the language of the novel and the way they can sometimes function on a metaphorical level. Furthermore, I examine how these discourses represent the change in the way modern humans relate to their own bodies and the bodies of the others.

The degradation behaviour of methylmercury (MeHg) under microwave irradiation is investigated, as is the (different) degradation behaviour of ethylmercury (EtHg) under similar irradiation. A simple and highly sensitive SPME-GC-pyrolysis-AFS system was used to analyse the aqueous MeHg and EtHg standard solutions after derivatization with sodium tetraphenylborate (NaBPh₄). Samples were irradiated in a microwave digester at microwave powers ranging from 20 to 160 W for durations of 2 to 10 min. The different tolerances towards microwave treatment of the two organomercury species were evident. Practically no degradation was experienced for MeHg for up to 8 minutes of irradiation at 120 W or for up to 4 minutes at 160 W. Significant analyte loss was observed for EtHg after 2 minutes at 40 W of microwave power.

Okay is one of the most commonly used words in the English language. It is also one of the most commonly borrowed English-origin loanwords across all of the world's languages. Although there is a wealth of research on the communicative functions of English okay, there is comparatively little research on the many borrowings of the word in various other languages. In order to address this gap in the literature, this study explores the differences in discourse/pragmatic function between the English word okay, and the Japanese borrowing of the word, okkē.Extensive research in discourse analysis, pragmatics, and conversation analysis shows that English speakers use okay to accomplish a variety of discourse/pragmatic functions. The functions of okay established in the relevant literature are: (1) A marker of transition. (2) A structural marker in monologic speech. (3) A marker of irony or sarcasm. (4) A tag question. (5) A method of seeking or giving permission. (6) An assessment. (7) A response token. In order to determine which of the functions listed above can be accomplished by Japanese speakers when they use okkē, this study analyses audio and video data of Japanese native speakers playing an augmented reality game. Evidence from the analysed data shows that Japanese okkē is used by Japanese speakers to accomplish the following functions: (1) A marker of transition. (2) A marker of irony or sarcasm. (3) An assessment. (4) A response token. Additionally, it was found that the way in which Japanese speakers utilize okkē as a marker of transition is different in some cases from how English speakers utilize okay as a marker of transition. In group settings among Japanese speakers, the group members sometimes each repeat okkē tokens one person after another in order to indicate group consensus of readiness to transition. Other noteworthy differences found between okay and okkē are that (1) Okkē tends to appear as the only word within a turn more often than okay. (2) Okkē is used as a response token only to a completed utterance, while okay can be used as a response token to either a complete or incomplete utterance. (3) Unlike okay, okkē is sometimes used outside of any ongoing talk to mark physical action transitions such as walking to stopping.

A new selenized yeast reference material (SELM-1) produced by the Institute for National Measurement Standards, National Research Council of Canada (INMS, NRC) certified for total selenium (2,059±64 mg kg-¹), methionine (Met, 5,758±277 mg kg-¹) and selenomethionine (SeMet, 3,431±157 mg kg-¹) content is described. The ±value represents an expanded uncertainty with a coverage factor of 2. SeMet and Met amount contents were established following a methanesulfonic acid digestion of the yeast using GC-MS and LC-MS quantitation. Isotope dilution (ID) calibration was used for both compounds, using ¹³C-labelled SeMet and Met. Total Se was determined after complete microwave acid digestion based on ID ICP-MS using a ⁸²Se spike or ICP-OES spectrometry using external calibration. An international intercomparison exercise was piloted by NRC to assess the state-of-the-art of measurement of selenomethione in SELM-1. Determination of total Se and methionine was also attempted. Seven laboratories submitted results (2 National Metrology Institutes (NMIs) and 5 university/government laboratories). For SeMet, ten independent mean values were generated. Various acid digestion and enzymatic procedures followed by LC ICP-MS, LC AFS or GC-MS quantitation were used. Four values were based on species-specific ID calibration, one on non-species-specific ID with the remainder using standard addition (SA) or external calibration (EC). For total selenium, laboratories employed various acid digestion procedures followed by ICP-MS, AFS or GC-MS quantitation. Four laboratories employed ID calibration, the remaining used SA or EC. A total of seven independent results were submitted. Results for methionine were reported by only three laboratories, all of which used various acid digestion protocols combined with determination by GC-MS and LC UV. The majority of participants submitted values within the certified range for SeMet and total Se, whereas the intercomparison was judged unsuccessful for Met because only two external laboratories provided values, both of which were outside the certified range.

In the years following World War II, the radical structural transformation of Hungarian society and the establishment of the communist dictatorship affected the functioning of sports as a social subsystem. At the time, the Hungarian public still remembered the sporting successes of the Horthy era (the Berlin Olympics, the 1938 FIFA World Cup) from the previous decade. Thus, the Sovietization of sports as a social subsystem had two intertwining goals in Hungary: in addition to creating a new institutional framework for sports, the regime also had to ensure good results, which were regarded as a matter of prestige. Like the daily press, the schematic film productions of the era were also characterized by the ideological utilization of sports. A typical example of the schematic style was Civil a pályán [Try and Win, 1951] by Márton Keleti, which used classical comedy elements to bring together the world of the factory and the world of the soccer field. Keleti’s film was intended to popularize a centralized mass sports movement of Soviet origins called “Ready to work and fight” and to communicate the party’s message to professional sportsmen who were considering emigration. The two versions of Csodacsatár [The Football Star, 1956 and 1957], also by Keleti, reveal a lot about the changes that the role of sports in state propaganda and political image construction underwent after the loss to West Germany in the 1954 FIFA World Cup Final and then after the 1956 Hungarian Revolution. My paper seeks to interpret these films within the context of the era’s political and sports history.
