The insides of twelve drains in a cheese processing facility were swabbed over a period of five months. Bacterial DNA was isolated and quantified to ascertain the presence and abundance of the biofilm. Presence of Listeria spp. prs gene was found in four of the twelve drains, with one drain testing positive for the prs gene presence on three different occasions. 16S rRNA amplicon sequencing was conducted on the isolated DNA from two Listeria positive and two Listeria negative drains. The microbial community composition was evaluated. Most notably genera Streptococci and unclassified Lactobacillales were significantly different in abundance in the Listeria negative drains. Genera Flavobacterium and unclassified Xanthomonadaceae were found to be significantly more different in abundance in the LisTeria positive drains. The latter two genera were not previously associated with Listeria spp. or reported to be widespread in food processing environments (FPE), however, they help to illustrate the higher diversity that was seen in Listeria positive drains. This study suggests that even though the alpha diversity is not sigN ificantly different, there are differences between the drain biofilm composition between Listeria positive and Listeria negative drains, which can be further researched to ascertain how these organisms affect the presence of Listeria spp. inside drain biofilms.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139186067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This enables, for the first time, simulations of GOLEM's magnetic field. The computation mode put into operation simulates the magnetohydrodynamic equilibrium of a tokamak plasma based on a given plasma position or given currents in poloidal magnetic field coils. In order to set up NICE, a virtual model of GOLEM is introduced that includes axially symmetrical approximations of GOLEM's iron core and primary transformer coils. The results of NICE simulations are compared with experimental measurements, and it is shown that NICE simulations produce plasma equilibrium configurations typical for GOLEM. Nevertheless, a more detailed validation of GOLEM's virtual model and of the results of NICE simulations is to be performed in the future.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"48 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139185972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He discovers the falsity of libertarianism radically conceived, according to which (radical) indeterminism is required for free will. But if we show that radical indeterminism is false, and if we deny any type of compatibilism as well, a logical dilemma once called an \"Ancient Dilemma\" enters the scene: If neither determinism nor indeterminism is consistent with free will, then free will simply cannot exist. The author provides a solution for this dilemma, while attempting to prove human freedom consistent. As he believes, however, this cannot be done until some important distinctions are provided, especially between External and Internal Determinism. While the author refutes External Determinism (and External Compatibilism), he defends Internal (or Intellectual) Determinism (as well as respective compatibilism). In the ending passage of his treatment, the author compares his philosophical solution of the free will problem with some recent scientific theories, especially with the physicalistically concieved Law of Conservation of Energy.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139186084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern Japanese literature is full of elements that run against our everyday experience such as these and writings of female writers Tawada Yōko and Ogawa Yōko are especially inundated by disconcerting and puzzling dreamlike scenes. What meaning are they trying to convey? What function does their inclusion in the text fulfil? How do they influence structure of their worlds? These questions pose a vexing problem for anyone attempting to analyse many of the works of contemporary Japanese literature as it is not easy to find a suitable theoretical approach to answer them. In this paper through interpretation of two shorter works by both authors E.B.'s Unfulfilled Wish by Ogawa and The Bath by Tawada) using a theoretical framework based on unnatural narratology and fictional world theory I attempt to answer these questions and show the central role these elements fulfil in both world-formation and meaning-formation of the texts.

Starting from July 2020 with the strongly reddened nova V1391 Cas, we are continuously observing some novae in outburst. Here, we report the observations of 5 classical novae: Nova Cas 2020 = V1391 Cas, Nova Per 2020 = V1112 Per, Nova Cas 2021 = V1405 Cas, Nova Her 2021 = V1674 Her and Nova Vul 2021 = V606 Vul. The best at the end - the recurrent symbiotic nova RS Oph. In this paper, we report our photometric and spectroscopic observations. Thorough analysis is to be done in the near future. At this moment we want to highlight two important facts. In the case of V1405 Cas, we know the orbital period of the progenitor. The progenitor of V1674 Her is an intermediate polar with known white dwarf spin period. In both cases, it will be very interesting to compare the values after the nova explosion. In the case of V1674 Her, we have already measured both the orbital and the spin period.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130196983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mass transfer between the components of these interacting systems is responsible for the manifestations of their observed outburst activity. In this article, we present the results of determining the orbital period of AX Persei based on the analysis of its radial velocity curve. We used 75 radial velocities, out of which 45 were collected from literature and 30 were derived using the spectra from ARAS database. Two methods were used to determine the radial velocities: the Doppler shift measurement of the sodium absorption doublet and the cross-correlation analysis. The result of the period analysis of the radial velocities of AX Persei is the orbital period of 681.2 ± 4.2days, which is in good agreement with the value determined by our previous analysis of photometric variability of the symbiotic system as well as with the values derived by other researchers.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131190998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many times, however, mankind tends to leap before looking and focus on the exotic and the interesting instead of that which might not seem that special to most of us, but which which can be crucial for our survival. This way, many major and important issues in astrophysics - and sciences in general - can become overlooked and take very long to resolve. One such major issue in astrophysics is the behaviour of our closest star, the Sun. While we generally assume that we have a good idea about the most significant processes in the solar interior acting as its main energy source, our attempts at explaining the dynamics and structure of the solar atmosphere (the so-called corona) are still merely an educated guesswork at best. Due to several of the magnetohydrodynamic processes which we do not yet fully understand, the temperature of the solar atmosphere is very high compared to the layers underneath and reaches millions of Kelvins. Since this is where the major mass ejections occur, some of which might be directed towards the Earth causing geomagnetic storms, it is crucial that we start not only to fully understand these processes, but also to be able to accurately predict their outcomes. As will be shown in this text however, it is not only our limited understanding of the physics which prevents us from doing that; it is also the lack of computational resources. This paper firstly briefly discusses the basic physics behind the behaviour of the solar coronal plasma. Afterwards, it discusses the coronal heating problem in more detail and finally, it outlines the major challenges we currently face which seem to prevent us from efficient simulation and complete understanding of the behaviour of our closest star.","PeriodicalId":161839,"journal":{"name":"Journal of the ASB Society","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122127603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
