Published: March 2023

Vitamin D is a fat-soluble vitamin with multiple functions. However, the metabolism of people with different vitamin D concentrations is still unclear. Herein, we collected clinical data and analysed the serum metabolome of people with 25-hydroxyvitamin D (25[OH]D) ≥40 ng/mL (A), 30 ng/mL ≤25(OH)D <40 ng/mL (B) and 25(OH)D <30 ng/mL (C) by the ultra-high-performance liquid chromatography-tandem mass spectrometry method. We found that haemoglobin A1c, fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance and thioredoxin interaction protein were enhanced, while HOMA-β was reduced with the decrease of 25(OH)D concentration. In addition, people in the C group were diagnosed with prediabetes or diabetes. Metabolomics analysis showed that seven, thirty-four and nine differential metabolites were identified in the groups B vs A, C vs A and C vs B, respectively. Metabolites associated with cholesterol metabolism and bile acid biosynthesis, such as 7-ketolithocholic acid, 12-ketolithocholic acid, apocholic acid, N-arachidene glycine and d-mannose 6-phosphate, were significantly upregulated in the C group compared with the A or B groups. In conclusion, the disorder of vitamin D metabolism may be related to cholesterol metabolism and bile acid biosynthesis. This study provided a basis for exploring the possible mechanism leading to abnormal vitamin D metabolism.

EDUCATION VS. ENTREPRENEURSHIP – BETWEEN THEORY AND PRACTICE: THE CASE OF SMES IN POLAND
Authors: Janowski Andrzej , Gonchar Olga , Yakovyshyn Ruslan
Published: March 2023

The complexity of issues related to entrepreneurial activity is reflected in the discourse in the world of economic sciences that has been continuing for over 200 years. Nowadays, the development of organizational management environment is more and more extensive and, as well as in other highly developed countries, the sector of small and medium-sized enterprises in Poland plays a fundamental role in the economy. Yet, there are rising concerns towards the entrepreneurial education direction in world of science. The growing concern in the context of entrepreneurship education has caused a discourse on whether this scholar activity can affect the entrepreneurial effectiveness in practice. We conclude that the contemporary academic management papers are, in a vast majority, focused on theoretical aspects of entrepreneurship, students, granted programs and trainings, while the opinions of real entrepreneurs toward abovementioned valuable efforts are omitted. Therefore, we decided to explore practical entrepreneurial environment to address this gap. The research participants included 189 entrepreneurs (SMEs based) that had been operating continuously for minimum 20 years. We established three objectives of this paper: to analyze the relation between the individual level of education, its characteristics and entrepreneurial success; to evaluate the state educational support in real world entrepreneurial operations effectiveness; to identify educational opportunities and threats and estimate the future research trajectories in this area. Finally, the first attempt, in the world of science, was undertaken to verify whether there is a positive correlation between entrepreneurship teaching and its real effect on entrepreneurship in practice. We empirically prove that the (higher) education can be an obstacle on the path of entrepreneurial success. Additionally, conclusions establish a new perspective on the existing state of knowledge through constructing a bridge which will enable connecting academic efforts and expectations on the part of firm owners.

Molybdenum disulfide (MoS2) flakes, a semiconductor-like material having high surface area and versatile electronic structure finds application in numerous electrochemical energy storage devices. Boosting its surface properties improves the overall storage performance to a greater extent. This present research work focuses on the surface modification of MoS2 using Lithium stearate (LiC18H35O2). The LiC18H35O2 modification supports lithium intercalation between the layers of MoS2 thereby facilitating the exfoliation process and simultaneous modification of the flakes. The resultant samples were characterized using Xray powder diffraction (XRD), Raman spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, Thermogravimetric analysis (TGA), Scanning electron microscopy (SEM) and Energy dispersive x-ray (EDAX) analysis. EDAX results revealed that the stearate surface treated MoS2 samples exhibited larger increase in Carbon and Oxygen elemental concentrations, which further confirms modification. The modifier and the material itself have good lubricant properties suggesting lithium stearate assisted modification and exfoliation of MoS2 as a better choice to make composites with enhanced electrical and chemical properties suitable for energy storage applications in batteries and supercapacitors.

Besides genetic alterations, the cellular environment also determines disease onset and progression. When different cell types contribute to disease outcome, this imposes environmental challenges as different cell types likely differ in their extracellular dependencies. Hsa‐microRNA‐31‐5p (miR‐31) is highly expressed in keratinocytes of psoriatic skin, and we show that expression in keratinocytes is induced by limited glucose availability and enables increased survival under limiting glucose conditions by increasing glutamine metabolism. In addition, miR‐31 expression results in not only secretion of specific metabolites (aspartate and glutamate) but also secretion of immunomodulatory factors. We show that this miR‐31‐induced secretory phenotype is sufficient to induce Th17 cell differentiation, a hallmark of psoriasis. Inhibitors of miR31‐induced metabolic rewiring and metabolic crosstalk with immune cells alleviate psoriasis pathology in a mouse model of psoriasis. Together our data illustrate an emerging concept of metabolic interaction across cell compartments that characterizes disease development, which can be employed to design effective treatment options for disease, as shown here for psoriasis.

Deutsche Sprache im Großen Gymnasium der multikulturellen Stadt Osijek als Träger der mitteleuropäischen Kulturwerte – historischer Ansatz
Authors: Kordić Ljubica
Published: March 2023

Mehrsprachigkeit und Multikulturalität sind untrennbare Bestandteile der Identität der Stadt Osijek, in welcher die deutsche Sprache eine eigentümliche Rolle ausgeübt hat. In der Einleitung dieser Arbeit wird das multikulturelle und mehrsprachige Milieu der Stadt Osijek vom 17. bis zum 20. Jahrhundert als Grundlage der Entwicklung des essekerischen Dialekts dargestellt. Im Mittelpunkt der Untersuchung steht die deutsche Sprache als einer der Träger der mitteleuropäischen Werte, Kultur und Weltanschauung. Jene Werte haben Lebensweise der einheimischen Bevölkerung und Schwung im kulturellen und wirtschaftlichen Leben der Stadt im zweiten Teil des 19. und anfangs des 20. Jh. intensiv beeinflusst. Obwohl um die Mitte des 19. Jahrhunderts Kroatisch zur offiziellen Sprache erklärt wurde, war Deutsch im mehrsprachigen Milieu von Osijek in den ersten Jahrzehnten des 20. Jh. noch immer die gesprochene Stadtsprache. In seinem Klassischen (Großen) Gymnasium galt Deutsch lange Zeit als Unterrichtssprache, und, abhängig von der Muttersprache seiner Schüler, war es ihre Erst- oder Zweitsprache. Auf Grund der im Museum der Stadt Osijek und im Staatsarchiv im Fundus des klassischen Gymnasiums aufbewahrten Schuldokumentation werden die Lehrinhalte und die obligatorische Lektüre im Fach „Deutsche Sprache“ an diesem Gymnasium erforscht und analysiert. Das Ziel dieser Untersuchung ist es festzustellen, welche Werte und Weltanschauungen den Schülern durch den Deutschunterricht vermittelt wurden. Eine interessante Quelle der Informationen über die Werte und Erziehungsziele, die damals im klassischen Gymnasium von Osijek gefördert wurden, stellen die Themen der obligatorischen Aufsätze in deutscher Sprache dar, deren Listen in regelmäßiägen jährlichen Schulberichten des Gymnasiums zu finden sind. Im abschließenden Teil der Arbeit werden auch einige negative Züge des Lebens in einer multikulturellen Stadt erörtert, wo in verschiedenen sozialpolitischen Umständen um Übermacht gekämpft wurde.
Minimally Invasive Direct Coronary Artery Bypass Versus Percutaneous Coronary Intervention for Isolated Left Anterior Descending Artery Stenosis: An Updated Meta-Analysis
Authors: Zhang Shijie , Chen Shanghao , Yang Kun , Li Yi , Yun Yan , Zhang Xiangxi , Qi Xing , Zhou Xiaoming , Zhang Haizhou , Zou Chengwei , Xiaochun Ma
Published: March 2023

Background: The optimal revascularization strategy for isolated left anterior descending (LAD) coronary artery lesion between minimally invasive direct coronary artery bypass (MIDCAB) and percutaneous coronary intervention (PCI) remains controversial. This updated meta-analysis aims to compare the long- and short-term outcomes of MIDCAB versus PCI for patients with isolated LAD coronary artery lesions.
Methods: The Pubmed, Web of Science, and Cochrane databases were searched for retrieving potential publications from 2002 to 2022. The primary outcome was long-term survival. Secondary outcomes were long-term target vessel revascularization (TVR), long-term major adverse cardiovascular events (MACEs), and short-term outcomes, including postoperative mortality, myocardial infarction (MI), TVR, and MACEs of any cause in-hospital or 30 days after the revascularization.
Results: Six randomized controlled trials (RCTs) and eight observational studies were included in this updated meta-analysis. In total, 1757 patients underwent MIDCAB and 15245 patients underwent PCI. No statistically significant difference was found between the two groups in the rates of long-term survival. MIDCAB had a lower long-term MACE rate compared with PCI. Besides, PCI resulted in an augmented risk of TVR. Postoperative mortality, MI, TVR, and MACEs were similar between the two groups.
Conclusions: The updated meta-analysis presents the evidence that MIDCAB has a reduced risk of long-term TVR and MACEs, with no benefit in terms of long-term mortality and short-term results, in comparison with PCI. Large multicenter RCTs, including patients treated with newer techniques, are warranted in the future.

Authors: García Cáceres Rafael Guillermo , Salamanca Gómez Tatiana Paola , Rodríguez Alvarez Nini Johanna
Published: March 2023

El trabajo presenta una caracterización de cada uno de los procesos que se encuentran en la cadena de suministro del banano tipo exportación para el caso colombiano, esta fruta hace parte de la canasta familiar del país debido a su valor nutricional y el impacto que tiene en la empleabilidad generada de forma directa e indirecta. La metodología utilizada es propuesta por García y otros desde 2005. El valor agregado y el objetivo fundamental del artículo subyace en proporcionar un contexto descriptivo de carácter estratégico que facilita los procesos de toma de decisiones a los diferentes stakeholders de la cadena de suministro, esto se detalle en el desarrollo de los pasos metodológicos de la metodología que tiene como objetivos secundarios: identificar la misión de la Cadena de Suministro (CS), identificar y describir de manera sintética los agentes involucrados, productos y subproductos del banano, identificar la posición en la CS de los agentes del mercado, realizar una descripción del sistema logístico de la CS, y proporcionar un diagnóstico de la CS a través de la matriz de Debilidades, Oportunidades, Fortalezas y Amenazas. Los resultados de la caracterización muestran que en Colombia persisten problemas de competitividad logística por los altos costos de transporte derivados de deficiencias en la infraestructura vial en especial la terciaria; el monocultivo propicia la presencia de plagas y enfermedades resistentes, en especial hongos, que afectan la productividad y rentabilidad del cultivo por lo que se deben tomar medidas que permitan un cultivo más sustentable y sostenible. Como oportunidades se evidencia la necesidad de investigación para el aprovechamiento artesanal o industrial de la hoja y el tallo de la planta. La fortaleza de la CS se sustenta en su carácter exportador y su nivel de integración organizacional que le permite gozar de un mercado estable y unos precios sostenidos.
Multidimensionale Ansätze zur Bewertung von wirtschaftlichen Prognosen
Authors: Köhler Tim , Döpke Jörg
Published: March 2023

In der Betriebs- und Volkswirtschaftslehre muss regelmäßig die Qualität von Prognosen beurteilt werden. Meist wird dabei nur eine prognostizierte Variable berücksichtigt. Das ist aber unzureichend, wenn mehrere Größen zugleich vorhergesagt werden. Als wichtige Anwendung können Konjunkturprognosen gelten, in denen mehrere Zielgrößen zu einem Zeitpunkt prognostiziert werden. Dieser Beitrag stellt Verfahren vor, mit denen ein Vektor aus verschiedenen Prognosen evaluiert werden kann und erläutert diese anhand eines Beispiels. Datengrundlage hierfür sind die jährlichen Prognosen des Sachverständigenrats und der (Herbst-)Gemeinschaftsdiagnose für die Veränderungsrate des realen Bruttoinlandsprodukts sowie die Inflationsrate, die Arbeitslosenquote und die Veränderungsraten der preisbereinigten Ex- und Importe für den Zeitraum 1993 bis 2020.
El capitán Garcilaso y Garcí Pérez de Vargas: dos vidas paralelas en las obras del Inca
Authors: De Mora Valcárcel Carmen
Published: March 2023

En el presente artículo se examinan las similitudes entre dos textos del Inca Garcilaso: la «Relación de la descendencia de Garci Pérez de Vargas» y «La oración fúnebre de un religioso a la muerte de Garcilaso, mi señor», en la segunda parte de los «Comentarios reales». Asimismo, planteo una hipótesis fundamentada acerca de la autoría de dicha oración y analizo los paralelismos entre los dos personajes como punto de unión entre ambos textos. Un paralelismo cuya función primordial está destinada a reivindicar aquellos meritorios servicios prestados por su padre a la Corona española que nunca le fueron reconocidos.

Authors: Huamán Mariela , Olazábal-Loaiza Juan , San Martín Felipe
Published: March 2023

El estudio tuvo como objetivo evaluar el efecto de la proteína cruda (PC) de la dieta sobre el nitrógeno ureico sanguíneo (NUS) en alpacas y ovinos. Se utilizaron cuatro alpacas macho (53 ± 5 kg) y cuatro ovinos macho (24 ± 4 kg) en un diseño experimental de sobrecambio con un arreglo de cuadrado latino 4x4 (4 animales, 4 periodos y 4 tratamientos). Las dietas contenían 7, 10, 13 y 16% de PC y fueron elaboradas a base de harina de alfalfa, pajilla de avena y suplemento comercial de minerales y vitaminas. El alimento fue ofrecido ad libitum. Cada periodo tuvo una etapa de adaptación (10 d) y otra de evaluación (4 d) y los animales estuvieron en corrales individuales. Se realizó una regresión lineal entre los niveles de N de la dieta (variable independiente) y los niveles de NUS (variable dependiente) para cada especie, se comparó el intercepto y la pendiente entre ambas mediante t-Student. En ambas especies el NUS se incrementó con el nivel de PC de la dieta (p<0.05). Las alpacas con bajo nivel de PC en la dieta presentaron mayores niveles de NUS que los ovinos (p<0.05); sin embargo, los ovinos mostraron mayor aumento de NUS por unidad de PC de la dieta (p<0.05). Se concluye que, si bien existe una relación directa entre NUS y los niveles de PC de la dieta en ambas especies, las tasas de incremento son diferentes entre ellas.
Improving Physical Fitness Assessment through Movement Tests: Overcoming Implementation Challenges in General Educational Schools
Authors: Vaskov Yurij
Published: March 2023

Background and Study Aim. The use of objective means and criteria for evaluating the educational achievements of students is crucial to improve the quality of education. Movement tests have been considered as a tool to assess the physical fitness of students in physical education classes. However, there are challenges in implementing these tests effectively. This article aims to address the problem of implementing movement tests in physical education classes in general educational institutions.

Methodology. The study utilized publications from the Vernadskyi National Library and the Google search system. Keywords were used for the search in accordance with the topic of the study. A total of 27 sources were selected for analysis.

Results. The study found that the effective implementation of movement tests in physical education classes requires an in-depth medical examination of students, consideration of each student's reaction level to physical loads, and the use of motor tests solely for evaluation purposes. The study also highlighted that motor tests can help solve complex pedagogical tasks and should meet criteria such as availability, indifference, reliability, capacity, and informativeness.

Conclusions. The study concludes that joint activity between teachers and students is essential for increasing the level of physical fitness. Furthermore, teachers must exercise systematic control of students' health status and their reaction to physical exertion in class. The results of this study can provide insights to educators and policymakers in designing effective physical education programs that include movement tests as an assessment tool.
Spectres of John Ball: The Peasants’ Revolt in English Political History, 1381–2020
Authors: Crossley James
Published: March 2023

For centuries, the priest John Ball was one of the most famous — or infamous — figures in the history of English rebels. Ball was one of the central figures of the Peasants’ Revolt of 1381 and was soon vilified, receiving a hostile press for 400 years as an archetypal enemy of the state and a religious zealot. His reputation was rescued at the end of the eighteenth century, and, for over one hundred years, he rivalled Robin Hood and Wat Tyler as a great English folk hero. But his 640-year reception involves much more. Spectres of John Ball explains how we get from an apocalyptic priest and advocate for violent retribution to someone who promoted democracy and vague notions of love and tolerance. This book also explains why he has gone out of fashion — and whether he can make another comeback.

Authors: Nguyen Uyen Quynh , Nguyen Hong , Van Giang , Nguyen Phuong , Dao Ha , Nguyen Ha , Le Hoang , Hoang Vinh
Published: March 2023

Abstract Products containing beneficial bacteria for humans have been widely used recently. The bacteria in these products generally belong to the genus Lactobacillus. Among the species of this genus, Lactobacillus casei attracts a lot of interest due to their valuable properties. With these properties, many L.casei strains can be used as probiotics. Based on the recommendation of FAO/WHO for probiotic bacteria, in our study strain LC 304.08 was identified based on morphology and biochemical properties as well as nucleotide sequence of 16S rDNA. The strain was then evaluated for its properties in vitro such as the ability to survive at low pH and in the presence of bile salt, the ability to produce antibacterial substances and enzyme as well as its safety regarding hemolytic and antibiotic resistance. The results showed that the strain was identified as Lactobacillus casei. It survived well at low pH and in the presence of bile salt, and it produced β-galactosidase with the activity of 81 ± 1.1 (U/mL). In addition, the strain was safe regarding its hemolytic activity and antibiotic resistance.

Artykuł ukazuje dzieje Wyższego Seminarium Duchownego w Sandomierzu w latach 1939–1945. Problematykę tę przedstawiono w czterech częściach. Pierwsza z nich jest zatytułowana Kontekst historyczno-prawny i ukazuje sytuację społeczno-polityczną Sandomierza w latach II wojny światowej, represje stosowane przez okupantów wobec seminariów duchownych na terenie Polski oraz sposób finansowania sandomierskiej uczelni. Druga część pt. Obsada personalna zajmuje się pracownikami zakładu: zarządem, profesorami i tworzoną przez nich radą pedagogiczną, a także pozostałymi pracownikami, czyli siostrami zakonnymi i osobami świeckimi zajmującymi się utrzymaniem placówki. Trzeci fragment pt. Alumni traktuje o klerykach: ich liczbie i pochodzeniu, a także o codziennym życiu seminaryjnym. Ostatnia część jest opisem formacji seminaryjnej. Ukazuje zatem metody formacji intelektualnej i duchowej alumnatu w omawianym okresie. Opracowanie kwestii zawartych w artykule stało się możliwe dzięki szerokiej kwerendzie źródłowej, m.in. w Archiwum Diecezji Sandomierskiej, Archiwum Wyższego Seminarium Duchownego oraz w Bibliotece Diecezjalnej w Sandomierzu. Artykuł jest uzupełnieniem dotychczasowego stanu wiedzy o dziejach seminarium duchownego w Sandomierzu oraz o funkcjonowaniu Kościoła katolickiego w czasie II wojny światowej.
Stawanie się darem jako realizacja człowieczeństwa
Authors: Trybek Justyna
Published: March 2023

Niniejszy artykuł przedstawia Boży pomysł na przeżywanie ludzkiego życia, wedle którego człowiek spełnia siebie, stając się darem. Poddaje analizie biblijne opisy stworzenia człowieka oraz teksty Karola Wojtyły – Jana Pawła II dotyczące myśli personalistycznej, a także teologii ciała. Przedstawiona w tekście norma personalistyczna, zgodnie z którą człowiek jako osoba ma swoją niezbywalną godność i wartość, kształtuje właściwe odniesienia we wszelkich relacjach międzyludzkich. Kluczowe dla przeżywania tych relacji jest spotkanie z Chrystusem, który jest Miłością, jako jedyny może więc pomóc człowiekowi zrozumieć samego siebie. Równocześnie odkrywanie oblubieńczego sensu ciała prowadzi do ofiarowywania siebie jako daru w sposób całkowicie wolny i bezinteresowny. Na gruncie wzajemnej wymiany darów rodzi się komunia osób – communio personarum. Człowiek, będąc stworzonym na obraz i podobieństwo Boże, poprzez bezinteresowną wymianę darów odzwierciedla wewnętrzne życie Osób Bożych. Stawanie się darem jest drogą prowadzącą człowieka do realizowania w pełni swojego człowieczeństwa.
Platońska doktryna wojny sprawiedliwej
Authors: Krzos Bartłomiej
Published: March 2023

Chrześcijańska koncepcja wojny sprawiedliwej należy bez wątpienia do znaczących osiągnięć cywilizacji. Owa wypracowana przez św. Augustyna koncepcja opiera się na fundamentach filozofii platońskiej. Za Platonem można podzielić wojny – a w szerszym znaczeniu konflikty i rywalizacje – na wewnętrzne, czyli toczone przez człowieka z samym sobą oraz toczone wśród swoich i przeciwko swoim, a także na zewnętrzne toczone z wrogami. Dąży się w nich do zapanowania wyższego nad niższym, i to przede wszystkim wśród wartości boskich. Czyli ma panować rozum w człowieku, filozof w państwie i mądrość między narodami. Ale rozum rządzi sprawiedliwością i harmonią, a więc pojednaniem, a nie zniszczeniem siły przeciwnej. Tylko w takiej sytuacji ma się do czynienia z człowiekiem sprawiedliwym i sprawiedliwym państwem, a takowe jest usprawiedliwione w przypadku prowadzenia wojen.
Problem zaangażowania w filozofii Józefa Tischnera – wybrane tropy
Authors: Stachurski Michał
Published: March 2023

Zagadnienia związane z zaangażowaniem coraz częściej pojawiają się w literaturze na temat zarządzania zasobami ludzkimi, są również poruszane przez osoby, które na co dzień zajmują się wolontariatem oraz aktywnością na różnych płaszczyznach życia społecznego, czy też szerzej: publicznego. Ujęcie Tischnera trzech form zaangażowania: wychowawczej, zawodowej i politycznej, ukazuje szerokie spektrum problemu, przede wszystkim pod względem etycznym. Zaangażowanie dotyczy nie tylko wykonywania powierzonych zadań, czy to w związku z przyjętymi rolami społecznymi, czy zawodowymi. Tischnerowskie myślenie na temat wszelkiego działania i aktywności ludzkiej krąży wokół wyboru wartości oraz budowania własnej autentycznej bądź nieautentycznej tożsamości, również za pomocą takiego narzędzia, jakim jest dialog. Celem artykułu jest przedstawienie najważniejszych refleksji Józefa Tischnera nad zaangażowaniem społeczno-politycznym w aspekcie etycznym (aksjologicznym).
Community Music Therapy in the United States: A Thematic Analysis
Authors: Murphy Kathleen M. , Krüger Viggo , Pomerselig Noah , Stige Brynjulf , Washington-Guillemet Rhé
Published: March 2023

Community Music Therapy (CoMT) practices are continuing to develop within the international music therapy community. However, the development and implementation of music therapy through a CoMT lens in the United States has not been widely written about. Only a handful of published studies and clinical reports detail music therapy programs that seemingly fit within a CoMT framework. In comparison to more traditional approaches to music therapy practice, CoMT practices in the United States are underrepresented. This thematic analysis informed by a hermeneutical method was undertaken to begin a dialogue with music therapists who consider their music therapy practice to fall within the boundaries of CoMT, in order to increase awareness of ways in which CoMT principles are being implemented within the US healthcare and educational systems. We interviewed 6 board certified music therapists asking them to 1) define CoMT, 2) explain role relationships (therapist, client, and community), and 3) speculate on how their approach to the work could influence health policy and access to services in the United States. Our findings suggest that participatory, performative, and social action elements of CoMT are evident in the clinical work of the music therapists who were interviewed, and that there is a place for CoMT practices within the United States healthcare system.
Postmodern Music Therapy
Authors: Gross Robert
Published: March 2023

Postmodern music therapy is an approach to music therapy that defines itself in diametric opposition to modernist, or medical-model, music therapy. Where modernist music therapy ignores power dynamics and assumes itself to be value neutral, postmodern music therapy is concerned with power dynamics between client, therapist, and broader society.  Postmodern music therapy is based on the theories of Bradley Lewis: Lewis (2006) believes that a postmodern psychiatry (or as he calls it, postpsychiatry) will be more aware of politics and social structures in general and will move toward democratization. This article proposes a postmodern music therapy in parallel to postpsychiatric ideas and ideals. Further, the article explores the intersectional nexus between postmodern music therapy and critical race, disability, queer, and feminist studies.

Following a preliminary assessment of bridge replacement/rehabilitation options for the existing Greenock Creek Bridge located near Walkerton in Southwestern Ontario, Canada, the removal of the existing superstructure and the reuse of the existing foundations was selected as the preferred option. The preferred alternative was based on a condition survey of the deck and superstructure and traffic mobility, economic, sustainability and environmental advantages. The decision is demonstrative of the Ministry of Transportation’s commitment to assess new technologies and applications that support ministry initiatives and operational needs and specifically to encourage the reuse of existing foundations. This paper describes the process of evaluation of the capacity, integrity and durability of the existing steel HP310x79 H-piles. A comprehensive programme was planned, organised and implemented that included exploratory boreholes to verify the subsurface conditions, retrieval of soil samples to determine the corrosivity of the soil and groundwater around the piles to assess the degree of corrosivity and geophysical testing including parallel seismic and borehole magnetometer testing to estimate the embedment lengths of the existing steel piles. The results of this investigation were used to assess if the existing steel pile foundations can carry the new superstructure loads for another 75 years.

Research background. The presence of Yersinia enterocolitica on raw food products raises the concern of yersiniosis as most of the berries are consumed raw. This is a challenging issue from the food safety aspect since it could increase the occurrence of foodborne diseases among humans. Thus, it is crucial to implement an effective sanitation before the packaging.
Experimental approach. This study aims to synthesize and characterize thymol-loaded polyvinyl alcohol (Thy/PVA) nanoparticles as a sanitizer for postharvest treatment of blueberries. Thy/PVA nanoparticles were characterized by spectroscopic and microscopic approaches, prior to the analyses of antimicrobial properties.
Results and conclusions. The diameter size of the nanoparticles was on average 84.7 nm, with a surface charge of −11.73 mV. Based on Fourier transform infrared (FTIR) measurement, the Thy/PVA nanoparticles notably shifted to the frequency of 3275.70, 2869.66, 1651.02 and 1090.52 cm–1. A rapid burst was observed in the first hour of release study, and 74.9 % thymol was released from the PVA nanoparticles. The largest inhibition zone was displayed by methicillin-resistant Staphylococcus aureus (MRSA), followed by Y. enterocolitica and Salmonella typhi. However, amongst these bacteria, the inhibition and killing of Y. enterocolitica required a lower concentration of Thy/PVA nanoparticles. The treatment successfully reduced the bacterial load of Y. enterocolitica on blueberries by 100 %.
Novelty and scientific contribution. Thymol is a plant-based chemical without reported adverse effects to humans. In this study, by using the nanotechnology method of encapsulation with PVA, we improved the stability and physicochemical properties of thymol. This nanoparticle-based sanitizer could potentially promote the postharvest microbiological safety of raw berries, which may become an alternative practice of food safety.
FACTORS OF SPATIAL DEVELOPMENT AND SUSTAINABLE FUNCTIONING OF THE REGIONS OF THE VOLGA FEDERAL DISTRICT
Authors: Khisaeva A.I. , Yapparov V.R..
Published: March 2023

The article analyzes the factors of spatial development of territorial entities included in the Volga Federal District – a region with a developed innovation-technological and industrial complex, with an economy that demonstrates sustainable growth rates not only in industries with traditional specialization, but also in economic areas of activity focused on providing services and the production of consumer goods. Analytical and statistical data of federal and regional state statistics bodies for the period from 2017 to 2021 were used as a basis for studying the features of the spatial development of territorial entities. In order to predict changes in the indicators under consideration, we also analyzed the trends in socio-economic transformations of Russia's space this year. The economic component of the group of factors of spatial development and sustainable functioning of regions was expressed through an analysis of the dynamics and structure of the gross regional product, the level of debt burden, indicators of self-sufficiency, deficit and liquidity of local budgets. The social component of spatial development was determined using the coefficients of migration and natural increase, the level of demographic load and unemployment in the regions, as well as through a comparative analysis of the population's monetary income in the regional context relative to the federal districts of the Russian Federation. The environmental factors of sustainable functioning of the territories were identified by the method of a comprehensive assessment of the state of the environment with the determination of quantitative and qualitative indicators of anthropogenic impact. As a result of the analysis of a group of factors of an economic, social and environmental nature, the leading regions in terms of the implementation of the resource potential and territories that stably lag behind the pace of development in certain directions and areas were identified. Based on the data obtained, spatial differentiation and uneven development of the regions of the Volga Federal District were proved, as well as the need to balance all components of the system of sustainable functioning of the region, visible in the application of the principle of unity of potential opportunities for economic, social and environmental development.
A Corpus-Based Study of the Translator’s Style of Two Versions of Fu Sheng Liu Ji —Take Pratt & Chiang Su-hui’s and Graham Sander’s Versions as Examples
Authors: Chen Meiru , Qu Xin
Published: March 2023

Fu Sheng Liu Ji is not only an autobiographical prose written by Shen Fu in the Qing Dynasty, but also a love letter to his wife. So far, there have been four English versions of it, translated by Lin Yutang, Shirley M. Black, Leonard Pratt & Chiang Su-hui, and Graham Sanders respectively. Among them, Lin Yutang’s version has been widely studied, and Shirley M. Black’s version is different from the source text in terms of content and layout. Therefore, this research takes the co-translation version of Leonard Pratt & Chiang Su-hui and Graham Sanders’ version as the research object, builds a corpus, and adopts both qualitative and quantitative methods to make a comparison of the translator’s style between the two English versions from different perspectives—vocabulary, sentence, and discourse, analyzing the type/token ratio, lexical density, average word length, number of sentences, average sentence length and readability of the two versions. It is found that the type/token ratio, lexical density, average word length and average sentence length of Pratt & Chiang Su-hui’s version are lower than that of Sanders’ version, and Pratt & Chiang Su-hui’s version is easier to read than Sanders’ version.
