Geochemical investigation of tar balls collected on a beach on Žirje Island (Croatia) using petroleum biomarkers
Authors: Marinović Slavica , Fajković Hana , Cuculić Vlado
Published: May 2021

Tar balls are frequently reported as indicators of the extent of marine pollution owing to spill incidents of crude oil or petroleum products. Representative tar ball samples collected on a beach on Žirje Island, Croatia, were geochemically characterised by gas chromatography coupled to mass spectrometry (GC/MS) in order to identify correlations between them and investigate potential sources. The chemical analysis of petroleum biomarkers, hopanes, and steranes, detected by gas chromatography/mass spectrometry (GC/MS) generates information of great importance to environmental forensic investigations in terms of determining the source of spilled oil, differentiating and correlating oils, and monitoring the degradation process and weathering state of oils under a wide variety of conditions.
The chromatographic signatures of hopane and sterane biomarkers in tar ball samples from Žirje Island were compared. Characteristic hopane and sterane fingerprints show that all the tar ball samples originated from crude oil spills. This study indicates that, the major source of tar balls was likely to be the same type of crude oil as evident from the petroleum biomarker fingerprints.

Velika ekonomska kriza koja se u posljednjem desetljeću osjeća u cijelom svijetu ponovno je potakla razmišljanja o potrebi “reindustrijalizacije”. Reindustrijalizacija je ekonomski, društveni, ekološki i politički proces upravljanja nacionalnim resursima s ciljem revitalizacije industrije i ostalih gospodarskih aktivnosti, a oslanja se na razvoj i primjenu novih i inovativnih tehnologija. U okviru takvih nastojanja kemijsko inženjerstvo ima odlučujuću ulogu. Prema mišljenju mnogih znanstvenika reindustrijalizacija i razvoj “industrije za budućnost” temeljit će se na tri ključna područja: očuvanju i remedijaciji okoliša, uštedi energije i poticanju razvoja obnovljivih izvora energije te zaštiti ljudskog zdravlja. To nameće i potrebu prilagodbe sustava visokog obrazovanja novim industrijskim i ekonomskim izazovima.

U novije vrijeme sve se češće susrećemo s postignućima koja izlaze iz okvira “tradicionalnog” kemijskog inženjerstva, a uglavnom se zasnivaju na primjeni novog pristupa poznatog pod nazivom intenzifikacija procesa. Znanstvenici i inženjeri intenzivno rade na otkriću novih procesnih uređaja i tehnika, što predstavlja velik iskorak u odnosu na dosadašnja saznanja o kemijskim procesnim postrojenjima i omogućava razvoj integriranih, sigurnijih, energetski učinkovitijih i ekološki prihvatljivijih tehnologija. Zahvaljujući snažnom razvoju znanosti i sve većem interesu javnosti za to područje, intenzifikacija procesa postupno se počinje izdvajati kao nova disciplina unutar kemijskog inženjerstva.

Zbog opsežnosti problematike u ovom radu ilustrirani su primjeri naprednih izvedbi fotokatalitičkih reaktora razvijenih primjenom metodologije intenzifikacije procesa, uključujući fotokatalitičke reaktore s rotirajućim diskom/bubnjem, mikroreaktore, membranske reaktore (sa suspendiranim i imobiliziranim fotokatalizatorom), keramičke monolite s optičkim vlaknima te uobičajene izvedbe solarnih reaktora. Istraživanja u tom području predstavljaju velik izazov s obzirom na mogućnost primjene takvih sustava za rješavanje globalnih problema u zaštiti okoliša, primarno onih vezanih uz pročišćavanje voda, otpadnih voda, uključujući i uklanjanje postojanih organskih spojeva i patogenih mikroorganizama iz vodenih resursa.

Published: May 2021

Background

We aimed to investigate early arteriosclerosis and its risk factors in populations with prediabetes and new-onset diabetes.

Materials and methods

A total of 148 participants who did not have diabetes mellitus were assigned to three groups through an oral glucose tolerance test: the normal glucose tolerance (NGT) group; the impaired glucose regulation, also known as prediabetes group and the new-onset type 2 diabetes mellitus group. The insulin resistance index was assessed using the homeostatic model assessment of insulin resistance (HOMA-IR). An ELISA was used to determine the level of fibroblast growth factor 21 (FGF21). An arteriosclerosis detector was used to measure the brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI). The baPWV, ABI, and FGF21 were used to assess early arteriosclerosis.

Results

Significant differences in age, systolic blood pressure (SBP), fasting plasma glucose (FPG), 2-h plasma glucose (2hPG), 2-h insulin (2hINS), and HOMA-IR were found between the NGT group and the prediabetes and new-onset diabetes groups. All of the above, except 2hINS, showed an increasing trend. Moreover, the FGF21 was higher in the new-onset diabetes group than in the NGT group. The baPWV was higher in the new-onset diabetes group than in the other two groups, but no significant difference was noted in the ABI. Age, SBP, diastolic blood pressure, FPG, 2hPG, and FGF21 were positively correlated with the baPWV. In addition, FPG, SBP, FGF21, and HOMA-IR were independent risk factors for the baPWV.

Conclusions

Patients with prediabetes and new-onset diabetes may have more significant early arteriosclerosis. The blood glucose level and insulin resistance index may be independent risk factors for early arteriosclerosis.
Pyrolytic characteristics and kinetics of Guanzhong wheat straw and its components for high-value products
Authors: Hu Bingtao , Gu Zhaolin , Su Junwei , Li Zhijian
Published: May 2021

Wheat straw produced annually in the Shaanxi Guanzhong region is a potential biomass feedstock for the production of transportation fuels and specialized chemicals through combustion, pyrolysis, or gasification. In this work, the pyrolytic characteristics, evolved gas products, and kinetics of Guanzhong wheat straw and its components were first investigated with a thermogravimetry-Fourier infrared spectroscopy (TG-FTIR) system. A comparative kinetic study was conducted using different model-free methods of Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), Kissinger, and the Coats-Redfern methods. The main pyrolysis products identified by FTIR include H2O, CH4, CO2, and CO as well as aromatics, acids, ketones, and aldehydes. Kinetic results showed that the pyrolytic apparent activation energy of the straw is approximately 200 kJ/mol obtained via FWO and KAS methods at the conversion range of 0.4 to 0.75, which was 30 kJ/mol higher than the value 171.1 kJ/mol obtained by the Kissinger method. The apparent activation energy of cellulose in its main pyrolysis region is 135.5 kJ/mol and is about three times larger than that of hemicellulose (49.5 kJ/mol). The apparent activation energy of lignin at the temperature range of 45 to 116 °C was 34.5 kJ/mol, while that value at the temperature range of 120 to 252 °C was 6.64 kJ/mol.

Acute nonspecific abdominal pain in children is the most common problem requiring differential diagnosis with acute appendicitis. Scales for integrated assessment of individual symptoms and their combinations have been proposed and are constantly being developed that allow predicting the likelihood of acute appendicitis. Purpose to assess diagnostic value of Pediatric Appendicitis Score (PAS) in groups of children in different ages. Materials and methods. 374 children aged 4 to 15 years with acute abdominal pain were evaluated in prospective randomized blinded study. Statistical analysis: ROC – curves, specificity and sensitivity, positive and negative predictive values; Kullback criteria; logistic regression analysis; discriminant analysis. Results. Detection frequency and diagnostic significance of the PAS scale predictors as well as obtained results by using the Pediatric Appendicitis Score depend on children age significantly. In terms of diagnosis of acute appendicitis, the PAS scale shows the best results in older children. Conclusions. Results of Pediatric Appendicitis Score depend on children ages due to different diagnostic value of predictors used in the PAS scale. Pediatric surgeons should keep in your mind these data. Modification of the scale is required taking into account the patient’s age. Further analysis of the issue of PAS using is needed. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. The authors declare no conflicts of interests. Key words: acute appendicitis, children, diagnosis, PAS scale.

Acquired torticollis is not a separate disease rather a warning sign of an underlying disorder. The etiology of torticollis in children is quite wide. Hematogenous osteomyelitis of the first cervical vertebra (the atlas) is an extremely rare and potentially dangerous pathology. The aim is to acquaint physicians of different specialties with an extremely rare condition – acute hematogenous osteomyelitis of the atlas. Case Report. A case of osteomyelitis of the first cervical vertebra in a 7-year-old boy is presented. An important sign of the disease is torticollis. Conclusions. Hematogenous osteomyelitis of the atlas is an extremely rare and potentially dangerous pathology. Regardless of its incidence, it must be considered when examining a child with acquired wryneck. All the ENT specialists must possess the knowledge of this disease, as they are most likely the first doctors to see such a child. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: torticollis, osteomyelitis of the atlas, C1 osteomyelitis, vertebral osteomyelitis, children.
Santo Domingo, entre la historia y la tradición hagiográfica castellana (siglos XIII-XVI)
Authors: Nieva-Ocampo Guillermo
Published: May 2021

En el presente artículo, se expone en modo sintético el conocimiento actual que tene­mos sobre la vida de Santo Domingo, fundador de la Orden de Predicadores, y se analizan las fuentes con las que se había construido su hagiografía a lo largo del siglo XIII. A partir de ello, se examinan los agregados y aspectos que destacaron sobre la vida del santo los cronistas del siglo XVI, formados en los ideales de la regular observancia y en la crítica huma­nística, quienes, justamente, proponían al fundador como el modelo del fraile castellano observante. De hecho, las crónicas de la Orden deben ser considera­das como historias propiamente dichas, pero, sobre todo, como escritos de formación religiosa para los mismos frailes.

Juan Pablo II y los obispos polacos hablan sobre Iglesia y política a propósito de la primera visita papal a Polonia en junio de 1979
Authors: Pérez-López Pablo , Dulska Anna-K.
Published: May 2021

Presentamos la versión española de un documento editado hasta ahora solamente en polaco. Recoge la transcripción de una conversación mantenida por el Consejo General de la Conferencia Episcopal de Polonia y el papa Juan Pablo II el 5 de junio de 1979 en Częstochowa, en el curso del primer viaje de Juan Pablo II a Polonia, que se desarrolló en junio de ese año. Era su segundo viaje pastoral, después del que había realizado a México. Se trata de una fuente de gran riqueza. Recoge con una franqueza nada común las opiniones del papa y de los obispos polacos sobre el significado y el alcance del viaje papal. Trata esencialmente de cuestiones pastorales y eclesiásticas, pero no elude los temas políticos, abordados de forma directa, clara y muy significativa desde el punto de vista histórico. El texto nos ofrece de primera mano un retrato crudo y sencillo de cómo vivía la Iglesia católica la opresión comunista y qué esperaban de un viaje como el que realizaba Juan Pablo II, de cuya trascendencia eran plenamente conscientes los participantes en aquel diálogo. Al hilo de la conversación se tiene noticia de la idea que poseen los interlocutores de qué significa la acción de la Iglesia católica y su gobierno, de cuál es el papel que puede corresponder a la Iglesia en Polonia en el seno de la Iglesia Universal, de cuáles eran algunas de las prioridades de gobierno de Juan Pablo ii y de qué se esperaba de las autoridades comunistas y de otras autoridades religiosas en aquel momento y en el futuro.
Bohemian rulers of the Luxembourg dynasty and the Poděbrady family in the medieval Silesian and Kłodzko chronicles of canons regulars in Kłodzko, Wrocław and Żagań

Published: May 2021

The author based on three monastery chronicles of the Late Middle Ages analyses the method of portraying the Bohemian kings from the Luxembourg and Poděbrady families and tries to point out factors which influenced this method of chronicle narration. The sources for this article are canons’ regulars chronicles in Żagań, Wrocław and Kłodzko: Catalogus abbatum Saganensium, Chronica abbatum Beatae Mariae Virginis in Arena i Cronica Monasterii Canonicorum Regularium in Glacz. The figures of rulers appear in the chronicles mainly in the context of their relationships with the particular monastery, especially when it comes to property matters: granting, rights and taxes. The other aspect in which the rulers are mentioned in the chronicles are the conflicts between secular and Church power. From the analysis of the texts a conclusion can be drawn that the picture of the rulers is diverse in different places where the chronicles were written and the attitude of the local society towards the particular ruler. It is best seen on the example of George of Poděbrady, a Hussite on the Bohemian throne. The chronicle of Żagań has a separate position – apart from the local issues, it presents the general information, unrelated to Church, including the ruling persons.

Published: May 2021

The profession of a commercial agent is relatively young. It was established in the mid-nineteenth century, and at the end of the nineteenth century, its representatives already played important functions as intermediaries between industry and trade, and between wholesale and retail sectors. The text begins with a description of the different attitude of Poles and Jews to trade as a sector of the economy. Then, the author presents the history of the profession of a commercial agent (sales representative, deputy) with the specification of the recommended character traits (and physical conditions) for representatives of this profession. The basis of the main part of the text is the correspondence circulating between the commercial agent Hilary Mintz, who was a permanent representative in Katowice, and the owners of the Iron Casting Factory „Neptun” J. Mintz in Końskie. It is a colorful story about the working conditions of a sales representative, with its splendors and difficulties.
The Paradoxes of Person – Some Remarks
Authors: Mazur Piotr Stanisław
Published: May 2021

The goal of the article is to present and analyze the paradoxes of person in the historical, logical-epistemological, and systematic aspect. Their historical source should be sought already in the beginnings of philosophical reflection on the issue of personhood. The interpretation of this concept has been influenced by the Christian religion which contributed to highlighting the opposition between properties common to man and other beings, and those which distinguish him from those beings. It was finally reflected in the paradoxes of person which are construed today as the opposition between existence (being a person) and becoming; (ontic) non-communicability and (intentional) communicability; overtness (knowability) and covertness (essential unknowability); being a whole and being a part. These paradoxes, however, are not antinomies or paralogisms in the logical sense. They cannot be explained away by flaws in human thinking or cognition. They are an expression of the opposite properties of personhood which represent aporias – objective difficulties. As such, they arise from the way a person exists. The paradoxes of person are superimposed, so to say, onto the paradoxes of being, e.g. that of identity and change. They cannot be interpreted as compounds of being. Therefore, they are most often treated as a result of the complex, spiritual-corporeal structure of man. Another problem, just as important as the cause of paradoxes, is the question of their significance. For they may be interpreted as a manifestation of a way of personal being that extends between extreme (almost contradictory) poles; multifaceted, diverse, never limited only to the arrangement of particular properties which form the paradoxes, or to that which can be known through them.
Development of NiCrSiBC Weld Hardfacing Approach for P91 Steels Used in Steam Turbine Components
Authors: Naik H. V. , Kalyankar V. D.
Published: May 2021

Abstract: P91 steels are used as substrate material for steam turbine components like bush, valve seat internals, and engineering valves. These components have hardfacing of cobalt-based material to reduce the high temperature wear loss and to improve the surface hardness. However, delamination failure and higher heat affected zone (HAZ) hardness were identified challenges for P91 steels. Hence, this demands the development of a suitable weld hardfacing approach to resolve the said challenges. In this work, NiCrSiBC (Colmonoy 6) has been considered as a hardfacing material to replace cobalt-based Stellite 6 material due to elimination of radiation activity, lower cost, and higher coating hardness. FCAW and PTA techniques were used to deposit buffer layer (SS-309L) and hardfacing layer (NiCrSiBC) respectively. Sample WBL (with deposition of buffer layer) and sample WOBL (without deposition of buffer layer) are considered approaches to study the metallurgical characterization for each case. Higher coating hardness, lower HAZ hardness and lower Fe dilution were observed in sample WBL. Cr7C3, Cr2B, and Cr5B3 hard phases in block shape together with ϒ- nickel matrix solid solution was observed in coating region of sample WBL. Overall, sample WBL approach was considered to overcome weld hardfacing challenges for steam turbine industries.

Re(thinking) Critical Language Education with Children and Teacher Education During (and After) Pandemic Times
Authors: Kawachi-Furlan Claudia Jotto , Tonelli Juliana Reichert Assunção
Published: May 2021

ABSTRACT The aim of this article is to discuss teachers’ perspectives on how the COVID-19 pandemic has impacted the teaching of English to young learners (TEYL). We focused on one specific question (from a 10-question online questionnaire) in which participants shared their thoughts, experiences and concerns about TEYL in pandemic times. The answers were analyzed in a qualitative perspective, based on critical literacy research and studies in the field of TEYL. The results indicate the participants’ exhaustion due to dealing with unusual situations, and teaching focused exclusively on content in an attempt to show how teachers are reinventing themselves despite uncertainties and lack of training. The present moment requires reflections about goals and expectations in TEYL and in teacher education.
Delinking Multiliteracies and the Reimagining of Literacy Studies
Authors: Duboc Ana Paula Martinez , Souza Lynn Mario Trindade Menezes de
Published: May 2021

ABSTRACT This paper proposes to critically read the multiliteracies proposal through a decolonial lens. It has two fundamental aspects: one, of an epistemic nature, refers to the need to de-link the concept from a particular hegemonic scholarship so that local knowledge production may prevent literacy practices from universalisms and methodologization; the other, of a technological nature, refers to the need to de-link the concept of multiliteracies from its apparent subjection to the digital.
Efficient Local Search based on Dynamic Connectivity Maintenance for Minimum Connected Dominating Set
Authors: Zhang Xindi , Li Bohan , Cai Shaowei , Wang Yiyuan
Published: May 2021

The minimum connected dominating set (MCDS) problem is an important extension of the minimum dominating set problem, with wide applications, especially in wireless networks. Most previous works focused on solving MCDS problem in graphs with relatively small size, mainly due to the complexity of maintaining connectivity. This paper explores techniques for solving MCDS problem in massive real-world graphs with wide practical importance. Firstly, we propose a local greedy construction method with reasoning rule called 1hopReason. Secondly and most importantly, a hybrid dynamic connectivity maintenance method (HDC+) is designed to switch alternately between a novel fast connectivity maintenance method based on spanning tree and its previous counterpart. Thirdly, we adopt a two-level vertex selection heuristic with a newly proposed scoring function called chronosafety to make the algorithm more considerate when selecting vertices. We design a new local search algorithm called FastCDS based on the three ideas. Experiments show that FastCDS significantly outperforms five state-of-the-art MCDS algorithms on both massive graphs and classic benchmarks.
Earthquakes and dams: Remote and direct monitoring of UK earthquakes affecting dam infrastructure
Authors: Hawthorn David E. , Mosca Ilaria , Baptie Brian J. , Walker Alice
Published: May 2021

Although earthquake hazard in the UK is low, there is a long history of earthquakes that have been widely felt or in some cases caused damage. Although these events are relatively rare, earthquake hazard assessment is still required for structures, such as dams, where the consequence of failure may be very high. Since 1990 the UK has experienced more than 13 earthquakes of greater than magnitude 4. The largest recorded onshore earthquake was a 5.4 local magnitude (ML) (Lleyn Peninsula, 1984) and the largest offshore was the 6.1 ML (Dogger bank, 1931). Smaller earthquakes can also produce levels of ground motion more typically associated with larger earthquakes; for instance, if they are unusually shallow or otherwise close to a structure of interest. In this talk two different, but potentially complimentary, methods of monitoring reservoir infrastructure for the affects of earthquakes are considered: remote monitoring of a region with a rapid alert system combined with the use of ground motion prediction equations to assess the likely ground motions at facilities of interest and direct emplacement of seismic sensors in or around reservoir structures to provide absolute values of ground motion during an earthquake.

Why is it so rare and random to find pyre sites?
Authors: Fülöp Kristóf
Published: May 2021

The cremation rite is well-defined in space and time as it is the central part of a series of complex ritual events. Although it is one of the most significant and representative elements of the funeral, yet we know very little about it due to its destructive nature, the scarcity of pyre sites and the indirect character of cremated bones and artefacts found in graves. The two experimental cremations presented in this article, on the one hand, address this rare occurrence of pyre sites. On the other hand, by the detailed documentation of the cremation process and the formation of pyre sites, it is possible to examine in detail several new issues related to the pyre sites. Thus, the shape, orientation, dimension, and structure of the funeral pyre, as well as some moments of the cremation are discussed in detail. Furthermore, the representation of the body and pyre goods after the pyre’s burndown, the movement of artefacts during burning, and the watering of pyre remains, as well as the problem of the mixture are also examined. At the same time, the experimental observations also draw attention, besides the investigational possibilities, to the archaeological limitations of pyre sites.
Pre-Scythian burial in Tiszakürt
Authors: Mogyorós Péter
Published: May 2021

During its long history, humanity left traces everywhere, therefore it is inevitable that finds, hoards or burials are going to be found accidentally besides professional excavations. That kind of a discovery occurred in Tiszakürt (Hungary), where a grave of the Mezőcsát group has been found.In this paper the three vessels – two urns and a beaker – of the grave will be presented. We do not have the skeleton, however, we do have an exquisite description of the grave. This description is important since it allows us to examine the burial practice as well.
Öcsöd-Kováshalom. Potscape of a Late Neolithic site in the Tisza region
Authors: Füzesi András , Raczky Pál
Published: May 2021

The primary goal of the present study is the publication of the ceramic inventory from Öcsöd-Kováshalom, for which Dissertationes Archaeologicae, being an online journal, can provide the necessary space. We shall principally focus on the possible correlations between vessel forms and their decoration in our analysis, alongside the examination of other traits and dimensions. The ad hoc nature of the analysed finds, i.e. an assemblage of vessels that could be successfully refitted, nevertheless constrains the more general insights that can be drawn from this assemblage. Our primary focus is on three different groups of the site’s ceramic inventory, examined according to uniform criteria. The analytical units differ from each other in terms of size and, as a result, the quality of the recorded data. Until now, the so-called Tisza I and Tisza II cultural phases were essentially distinguished qualitatively, based on the differing ceramic style of the two superimposed occupationlevels (A and B) at Öcsöd-Kováshalom. We took a bottom-up approach in our analysis, moving from the deposits of individual contexts towards the entirety of the settlement. We also strove to extend the Tisza I and II developmental sequence to a larger region in the southern Hungarian Plain by looking at the contexts with similar ceramic patterns on other sites. The essence of our approach is encapsulated by Katalin Sebők’s model for the Late Neolithic of the Tisza region, in which ceramic vessels are enveloped by the different (research) aspect connected with several lines, reflecting the intricate relationships between them. This model takes stock of both the European and the American theoretical approaches and also incorporates elements of various approaches based on system and network theories that figure prominently in modern research agendas. Another inspiring aspect of K. Sebők’s initiative is that she moved beyond the traditional boundaries of pottery assessment and sought new avenues for meaningful analyses, which was also one of our priorities in the current assessment of the pottery finds from Öcsöd-Kováshalom. The settlement complex represents a specific initial phase in the Late Neolithic development of the Hungarian Plain in the Tiszazug micro-region. Its position in the Tisza culture’s formative phase determined the nature of the site, made up of a tell-like and a single-layer settlement, and its layout of a central settlement area surrounded by smaller settlement clusters within a large triple and segmented enclosure, as well as the community’s social and economic milieu. The finds and features brought to light at the site preserve the imprints of complex, multi-scalar processes in the community’s life. The main goal of the analysis of the assemblage of 240 refitted and reconstructed vessels was to examine and interpret the possible imprints of these multi-level changes.
‘All that glitters is not Roman’ - Roman coins discovered in East Java, Indonesia
Authors: Hoppál Krisztina , Vida István , Adhityatama Shinatria , Yahui Lu
Published: May 2021

Studying extra regional trade networks in Antiquity can be considered a relatively popular field of research, but the intensity and patterns of such complex system still leave lot of questions, particularly in the case of Rome’s Far Eastern trade. There is still a trend to visualize a kind of globalized commercial activity between the Imperium and communities on the eastern edge of the Silk Road(s). However, the facts provide us a more comprehensive picture. Due to the meticulous work of international joint research projects working in East and Southeast Asia followed by a raised interest in collecting ancient objects among local people, an increasing number of Roman objects have been discovered in the region. These finds prove the significance of mediator cultures in transferring Roman artifacts beyond India – with their own imprints on forming evaluation/acceptance of these non-local goods by the receiving culture.
Preliminary report on the excavation at Andornaktálya-Marinka in 2018
Authors: Mester Zsolt , Cserpák Ferenc , Faragó Norbert
Published: May 2021

Andornaktálya-Marinka is among the several Palaeolithic archaeological sites in the region of Eger, on the foothills of the Bükk Mountains, North-Eastern Hungary. It is situated on the top of a 234 m high elevation located between the villages Andornaktálya and Ostoros. The site was discovered in 2014 by Ferenc Cserpák. Surface collections yielded by several field surveys show two kinds of archaeological material: one is signified mostly by a bifacial-like industry made of quartz porphyry (metarhyolite), while the other one is abundant in blade-like pieces made of Silesian erratic flint. The main aim of the excavation carried out in summer 2018 was to obtain stratigraphic information about the position of the industries, as well as to characterize the quaternary sediments covering the hilltop. The artefacts unearthed in the five trenches occurred in a depth of 60 to 80 cm in a brown chernozem-like layer.

Colleagues of the Institute of Archaeological Sciences of the Eötvös Loránd University performed a rescue excavation at the site of Tiszakürt-Zsilke-tanya in 2018, within the series of excavations preceding the construction of the M44 motorway. Neolithic, Sarmatian, and Avar Age settlement sections and burials came to light on the hills situated on the left bank of the Tisza River. This preliminary report presents their most important finds and phenomena.
Recent excavations at the medieval castle of Bánd
Authors: Nagy Szabolcs Balázs
Published: May 2021

After the first minor investigations between 1997 and 2007 a new series of excavations have been conducted at the medieval castle of Bánd in 2013, 2017 and 2018.1 Although the scale of the latest works is still quite moderate compared to the dimensions of the fortification, the observations resulted not only in considerable amounts of find material but also in objects that raised important issues and unexpected questions. The archaeological evidence proves a special relationship between the castle and the medieval settlement(s) of Bánd, the details of which definitely call for further research.

The Role of Sun Symbols in the Burial Rite of the Middle Bronze Age Vatya Culture
Authors: Pásztor Emília
Published: May 2021

The case study investigates the burial customs of the Middle Bronze Age Vatya culture in the Carpathian Basin. It aims to deliver a comparative analysis of the archaeological finds and characteristics of several cemeteries where communities cremated and buried their dead in urns. It also examines the ways grave artefacts are placed, and the shape and ornamentation of ceramics. It also gives a concise review on beliefs related to cremation. The case study aims at presenting just how much information the seemingly monotone burial customs of the Vatya culture can offer on their belief system by analysing the shapes, arrangements and ornamentations of buried artefacts.The decoration of grave ceramics often includes solar – light symbols, therefore, the author argues that the regular use of light symbols has a significant role in their belief system, especially in the deceased’s journey to the Otherworld.
The Ritual Role of Wells beyond their Everyday Water-providing Function
Authors: Fülöp Kristóf
Published: May 2021

In 2011, in the Late Bronze Age settlement of Pusztataskony-Ledence, situated next to the Tisza River, a timber lined well (Kastenbrunnen, rováskút) with a preserved wooden structure and a large number of finds came to light. Based on the position, composition, and quality of the abundant finds found in the well infill, it is possible to reconstruct the manipulation and special treatment of household waste and its structured deposit at the well bottom. Throughout history, a series of diverse and complex rituals connected directly or indirectly to wells can be observed. This role derives from the close connection of man to water and the well. This function may appear earlier in the Life stage of the well’s life cycle, however, it culminates in the phase of Afterlife. By studying the Afterlife of the Pusztataskony well and other prehistoric examples, we attempt to outline and understand this special relationship. At the same time, we aim to define the archaeological characteristics and criteria to identify these ritual functions and meanings.

Background and Objectives: The diagnosis of acute coronary syndromes can be challenging inpatients admitted with the non-cardiac disease to the Intensive Care Unit (ICU). The study aimed todetermine the clinical profile of critically ill elderly patients developing myocardial injury who wereadmitted to ICU for non-cardiac diagnosis. Materials and Methods: The retrospective studysubjects are 130 patients admitted to the medical ICU. Within 24 hours of admission to ICU adetailed history, a 12 lead ECG, CK-MB, Cardiac troponin T was done and as required based on ECGfindings and development of clinical symptoms. Results: Our study showed that 35 out of 130patients developed acute myocardial injury. 13 out of 35 patients who had myocardial injury had afatal outcome. The prevalence of hypertension, diabetes mellitus, history of CVA, history of IHD andCOPD reached statistical significance (p<0.001) between the two groups of patients who developedmyocardial injury and who did not develop a myocardial injury. In patients with multiplecomorbidities, the presence of factors like hypoxia, hypotension and the use of vasopressorsincreases the risk of mortality. Conclusion: All elderly patients who are hospitalized with or withoutmultiple comorbidities with an acute form of stressors must be evaluated aggressively forprecipitants and adequately treated to prevent myocardial injury.

An important task in the development of training complexes is the implementation of physical processes in virtual space using the example of burning objects. To solve it, an adapted mathematical model is proposed that allows one to formalize the structure of combustion objects, their main properties and processes of changing states, starting from the ignition of the object and ending with their complete destruction or extinguishing. Original diagrams of the life cycle of virtual objects and a system of rules for changing their states have been developed, which allow tracing the entire life cycle of objects and the procedure for changing states. Each state and transition between them are clearly formalized and calculated on the basis of the properties of the object and external influences. The patterns of state change are formalized using a matrix representation of object properties. This approach is distinguished by its versatility and can be used to model other physical processes (smoke, flooding, freezing, spread of toxic gases, etc.). The practical implementation of the combustion process using the apparatus of life cycle diagrams of virtual objects has been carried out. The developed method has been successfully integrated into the Unity development environment. its use made it possible to reliably and efficiently implement the combustion process without losing performance, which is especially important for virtual reality systems.
