Connecting with family, friends and others
Authors: Sin I Lin , Schartner Alina
Published: September 2023

This article casts light on informal caregiving, an essential aspect of the international postgraduate researcher (PGR) experience, but which is often invisible in literature and discourses on international education. Drawing from qualitative semi-structured interviews with international PGRs in a British university, it highlights their dual role as care recipients and lesser known caregivers across transnational and local spaces. It gives insights into the forms and dynamics of care that they give to and receive from family, friends and others, uncovering the emotional and affective aspects of undertaking a postgraduate research degree overseas which impact on their mental wellbeing. The findings have implications for the improvement of university support for international PGRs which has relevance for the wider international student community.

Authors: Бобришев Євген
Published: September 2023

Стаття розглядає актуальну проблематику впливу фінансових технологій (FinTech) на стабільність національної економіки. Автори досліджують, як інновації у фінансовій сфері впливають на традиційні банківські та фінансові системи, а також розглядають можливості та виклики, які ці зміни приносять. Аналізуючи діючі моделі взаємодії FinTech з традиційною фінансовою системою, автори вказують на невід'ємну роль цифрової інтеграції в епоху інформаційних технологій. Особливий акцент зроблено на потребу створення гнучких регулятивних механізмів, які допоможуть адаптуватися до мінливості ландшафту фінансового ринку без жертвування фундаментальними принципами безпеки та захисту споживачів. Основна увага приділяється питанням регулювання, кібербезпеки, доступності фінансових послуг та їх впливу на соціально-економічний розвиток країни. В статті висвітлено, що належне використання та інтеграція FinTech може підвищити ефективність економічних процесів, сприяти фінансовій інклюзії та стимулювати економічний ріст, але також потребує вдосконалення механізмів регулювання та контролю. Тим не менш, переваги, які пропонує FinTech для національних економік, не можна ігнорувати. Ці технології відкривають нові горизонти для мікрофінансування, розширення доступу до банківських послуг для недостатньо обслуговуваних населених пунктів та підтримки інноваційних стартапів. Додатково, стаття висвітлює роль глобалізації у поширенні фінансових технологій та взаємодії між національними та міжнародними ринками. Аналізується, як FinTech може впливати на конкурентоспроможність національних банків та фінансових установ в умовах постійно змінного глобального ринку. Також в статті розглядається соціальний вимір фінансових технологій, зокрема їхній вплив на створення робочих місць, професійну підготовку та перепідготовку кадрів, а також на формування нового споживчого досвіду в сфері фінансових послуг. Висновки статті наголошують на важливості балансу між інноваціями та стабільністю, підкреслюючи роль урядових структур та приватного сектору у формуванні ефективного, безпечного та інклюзивного FinTech-середовища. Автори закликають до активної співпраці всіх зацікавлених сторін для забезпечення позитивного впливу фінансових технологій на національну економіку, при цьому усвідомлюючи можливі ризики та виклики.
Developing a Framework for Smart Supply Chain Risk Assessment
Authors: Khan Khalid
Published: September 2023

This research aims to provide a framework for assessing the smart supply chain risks using a quantitative approach. This study identifies the smart supply chain’s risk factors based on an extensive literature review and professionals’ interviews. Analyzing different concepts of the previous frameworks, a new one is proposed. This new framework is applied to the collected data from the survey with a sample size of 56 from Canadian supply chain professionals as respondents. We conducted an exploratory factor analysis to examine the construct validity of the survey results. Some constructs were developed after assessing risks for different smart supply chain risk factors. The survey’s results point out the most important risk factors for the smart supply chain, prioritized. These include risk of complexity, web application failure, talent shortage, and high-cost risk. The results also realize the most commonly implemented smart technologies in the supply chain sector: bar code and social media.

In ecology and evolution, genetic and genomic data are commonly collected for a vast array of scientific and applied purposes. Despite mandates for public archiving, such data are typically used only once by the data-generating authors. The repurposing of genetic and genomic datasets remains uncommon because it is often difficult, if not impossible, due to non-standard archiving practices and lack of contextual metadata. But as the new research field of macrogenetics is demonstrating, if genetic data and their metadata were more accessible, they could be reused for many additional purposes, far beyond their initial intended impact. In this review, we outline the main challenges with existing genetic and genomic data archives, factors underlying the challenges, and current best practices for archiving genetic and genomic data. Recognising that this is a longstanding issue due to an absence of formal data management training within the research field of ecology and evolution, we highlight key steps that universities, funding bodies, and scientific publishers could take to ensure timely change towards good data archiving.
Telepítés- és településpolitika a Dél-Alföldön a török kiűzésétől 1944-ig
Authors: Hajdú Zoltán
Published: September 2023

1683-ban a török vereséget szenvedett Bécs ostromakor. A győztes keresztény koalíció megkezdte a török által megszállt magyar területek felszabadítását. 1686-ban felszabadult Buda, s ezzel forduló pont következett be a felszabadító háborúban. 1688-ban Kollonics Lipót és szakértői csapata kidolgozta a teljes visszafoglalás utáni időszakra vonatkozó, szinte minden lényegi kérdést átfogó reformtervét. Egészében nem fogadta el a Habsburg-ház, de sok elemét megvalósította. A leglényegesebb elem a volt hódoltsági területek újbóli benépesítése volt. 1711 után kezdődtek meg igazán a tömeges betelepítések. Mária Terézia a Dél-Alföld területén kijelölte az új szabad királyi városokat, mint a térség jövőbeni központjait. A volt hódoltsági területen 1044 új, szabályos alaprajzú falut hoztak létre. A soknemzetiségűvé vált területen gyors helyreállítási, majd növekedési és gazdagodási folyamat bontakozott ki. Az I. világháború, illetve az országhatárok és impérium változások alapvető következményekkel jártak a lakosság egymás közötti viszonyaira. Az új délszláv állam erőteljes etnopolitikát folytatott a kisebbségek (mindenek előtt a magyarok és németek ellen). A II. világháború alatt ismét változtak a határok, s visszatért a terület egy részére a magyar hatalom. A bukovinai székelyek betelepítésével 1941-ben a magyar kormány szintén etnopolitikát valósított meg, a kiszorított szerbek helyére telepítették őket. 1944 őszén a székelyek nagy része elmenekült a Dunántúlra. A helyben maradt magyarokra a térség történetének egyik legvéresebb megtorlása várt.
Újvidék (Novi Sad) városfejlődése és regionális szerepkörének sajátosságai
Authors: Nagy Imre
Published: September 2023

A szerbiai Újvidék azon kevés európai városok egyike, amely a 20. század egyébként eseménytelen második felében drámai folyamatokkal terhelve lépett a 21. századba. A középső őskőkorszak (paleolitikum) óta tartó folyamatos fejlődés után a 19. századi kistelepülés a Duna menti bánság, majd a II. világháború után a tartományi közigazgatás, illetve a régió központjává nőtte ki magát. A stabil gazdasági növekedés megerősítette regionális szerepkörét, és Jugoszlávia felbomlását, majd az új állam geopolitikai helyzetének változását követően is a város területi és funkcionális szerepkörének fejlődése tovább tart, aminek következtében Szerbia második városává nőtte ki magát. A tanulmány felvázolja Újvidék urbanizációját és fejlődéstörténetét, morfológiai fejlődését, amelyet a demográfiai és regionális szerepkör változásának kölcsönhatása irányított, különös tekintettel a 20. század végének történéseire, valamint a 21. század elejének fejlődési próbálkozásaira.

Authors: Mekonnen Mulugeta , Kebede Ameha , Muthuswamy Manikandan
Published: September 2023

The chemical mutation is one of the important factors in the enrichment of the salt resistance capacity of the rhizobium isolates. Therefore, this study focused on 10 isolates of rhizobium collected from soil samples of Babile, Hararghe region, Ethiopia. All the collected isolates turned into a moderately yellow, yellow, and deep yellow color in yeast extract mannitol agar medium (YEMA) containing bromothymol blue after 48 h of incubation. It indicated that all the isolates were acid-producing Rhizobia. Moreover, based on colony morphology and diameter, 70% of the isolates displayed large mucoid colonies, and 30% of the isolates showed large watery colonies in YEMA media. Among the 10 isolates, 9(90%), 9(90%), 6(60%), 6(60%), 2(20%), and 1(10%), were grown at different salinity levels such as  2%, 4%, 6%, 8%, 9% and 10% of NaCl, correspondingly. The most salt-resistant wild isolate was HUCR 6 collected from Babile soil grown at 10% NaCl salinity level. A total of six mutants were considered after chemical mutagenesis based on their capacity to survive in the extreme salinity levels (11 to 14%). Mutant isolates such as HUCRM 4, HUCRM 5, and HUCRM 6 were the most tolerant Rhizobium that grew at the salinity level of 11 to 14% NaCl. The most sensitive mutant isolate was HUCRM 10 followed by the isolates HUCRM 8 and HUCRM 9 was the next sensitive mutant Rhizobia that grew only at 11% of NaCl concentration. Compared to the Rhizobium wild isolates, the mutant isolates were observed to be more tolerant to a medium containing higher concentration of NaCl, as high as 11% to 14%. Besides, 80% of the mutant isolates demonstrated effective nodulation with the common beans. The mutant isolate (HUCRM 4) showed better performance in relation to root nodule performance of Rhizobium species and increased the plant biomass production. In this study, mutant isolates HUCRM 6, which is tolerated to 14% NaCl, and HUCRM 4, HUCRM 5, and HUCRM 6 isolates tolerated at 12% salinity level. Finally, based on their symbiotic efficiency and tolerance to extreme salt levels, these mutant isolates (HUCRM 4, HUCRM 5 and HUCRM 6) were encouraged to be used for the development of Rhizobium inoculants of common beans grown under extreme saline conditions.

Authors: Aziz Md Saifullah Bin , Alam Md Mehedi , Haque Mohammad Mahfujul , Mondol Md Mostafizur Rahman
Published: September 2023

A study was conducted to examine the various factors influencing the decline in fish production in the Hakaluki Haor wetland ecosystem in northeast Bangladesh, aiming to investigate the impacts of both climatic and anthropogenic factors on fish production in the area. Nowadays, this wetland is increasingly impacted by climate change, which poses significant challenges to fish production and sustainability. The primary data were collected through a face-to-face questionnaire survey (n = 150) with fishers, focus group discussion (n =15), and key informant interviews (n = 10). The majority of the fishers were middle-aged group (31-50 year), whereas 41% had primary level (schooling year 5) of education and 48% were highly experienced fishermen (≤16 years). Stakeholder perceptions of human activities, including overfishing (52%), discard of non-target species (23%), use of destructive fishing gear (67%), beel drying (47%), habitat destruction (48%), water pollution (23%), migration route changes (30%) and agricultural intensification (45%), have been identified to reduce fish production. Additionally, the study revealed that climate change impacts the ecosystem, including temperature fluctuation (57%), erratic rainfall (49%), flood and flash flood (37%), drought (17%), and siltation in beel (37%). Stakeholders perceived these impacts to have significant negative effects on aquatic biodiversity, particularly in terms of habitat destruction and water quality degradation. This study proposes potential solutions to mitigate the impacts of climate changes and man-made factors associated with fish production reduction in the region, such as improved water management practices, diversification of fish species, and the use of climate-resilient fisheries management. Community engagement and government support are highlighted as crucial factors to address the impacts of climate change on fish production in Hakaluki Haor. The findings of this study have important implications for the development of effective management strategies for ensuring sustainable livelihoods for fishers.

Authors: Almeida Martha Elisa Ferreira de , Miranda Jhonatan Alves de , Cavicchia Luis Otávio Aguiar
Published: September 2023

O Diabetes mellitus tipo 1 é uma desordem metabólica que tem como característica a destruição das células β-pancreáticas através da resposta autoimune, gerando um déficit na síntese de insulina que resulta em um quadro de hiperglicemia e necessita do tratamento à base de insulina. A contagem de carboidratos é o método mais eficiente para o controle glicêmico e o cálculo de insulina por refeição. O objetivo deste trabalho foi avaliar os conhecimentos dos nutricionistas egressos da UFV/CRP sobre o manejo deste tipo de diabetes quanto a contagem de macronutrientes e as unidades de insulina. O estudo exploratório e descritivo foi realizado por um questionário elaborado no Google Forms, contendo perguntas para a descrição geral dos avaliados e 10 questões para avaliar o nível de conhecimentos. Os dados estão apresentados nas frequências absoluta e relativa. Quanto ao conhecimento, 54,54% apresentaram a classificação bom, e apenas 3,03% foi ruim. Na distribuição dos pontos a maioria apresentou notas entre 7 a 9 pontos, sendo que nenhum dos participantes obteve as notas 1, 2 e 10. Conclui-se que a maioria dos participantes tinham conhecimentos sobre o manejo desta patologia quanto a contagem de macronutrientes e as unidades de insulina, entretanto justifica-se a necessidade de treinamentos como palestras e minicursos para este público, visto que alguns erraram algumas questões básicas e específicas sobre o assunto.
Gastrosquise: Relato de Caso
Authors: Souza Isabely Dias de , Eloi Maísa Galdino , Requeijo Márcio José Rosa
Published: September 2023

A gastrosquise é uma anomalia congênita que afeta o fechamento da parede abdominal, deixando o intestino exteriorizado. É visto que essa alteração morfológica vem apresentando maior incidência, devido a fatores sociais, ambientais e genéticos. Sendo assim, a utilização da ultrassonografia no pré-natal mostra-se cada vez mais importante na sociedade atual, pois é através dela que se identificam as alterações na formação do feto e possibilita a condução do caso da melhor forma possível. Este trabalho trata-se de um relato de caso descritivo e qualitativo. O objetivo desse estudo é descrever o diagnóstico de um caso de gastrosquise paraumbilical à direita do coto umbilical, identificada desde o primeiro trimestre, na qual o feto apresentava sinais sugestivos da má formação. A paciente e o feto tiveram um acompanhamento assíduo com confirmação pós-natal, com nascimento as trinta e cinco semanas e cinco dias. Devido à prematuridade o recém-nascido foi encaminhado a Unidade de Terapia Intensiva (UTI) neonatal.

Authors: Silva Anderson Antonio Neto da , Belluzzo Maria Elaine Campos Steele , Bastos Rejiane Avelar
Published: September 2023

Esta pesquisa teve como objetivo avaliar o comportamento dos consumidores em relação aos produtos diet e light. Foi realizado por meio de uma pesquisa de mercado com aplicação de um questionário estruturado na cidade Barbacena-MG no primeiro semestre de 2019, constituída por 385 indivíduos. Seguido de uma avaliação da aceitação com escala hedônica de 9 pontos com iogurte nas versões tradicionais, light e zero, ocorreram em duas situações às cegas e com informação das versões. Por fim, aplicação das sessões de grupo focal. Dentre os participantes do teste, a maioria era do gênero feminino, sendo a minoria os que afirmam consumir produtos diet e light, apontaram a dieta como principal motivo para o consumo. Os alimentos mais consumidos, destaca-se o iogurte, seguido do refrigerante. Em relação à influência da informação na avaliação dos produtos, observou-se que a informação sobre a versão do iogurte (light, zero ou tradicional) não afetou a aceitação dos produtos. Os resultados sugerem que o nível de conhecimento dos consumidores sobre alimentos diet e light é baixo e muitas vezes fazem confusão com estes dois produtos.

Probing compact objects with gravitational waves
Authors:   , Gupta Pawan Kumar
Published: September 2023

In 2017, the first gravitational wave signal from a binary neutron star merger, GW170817, was detected by both Advanced LIGO and Advanced Virgo. From this merger, a gamma ray burst was detected by the Fermi Gamma-ray Space Telescope and the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) spacecraft which initiated a new era of multi-messenger astronomy.

Neutron star matter
Neutron stars are the most densest objects in our universe which are formed in su- pernova explosions. This makes neutron stars ideal astrophysical laboratories for testing theories of dense matter physics. A typical neutron star has a mass of the order of 1.4 solar masses and a radius of 12 km. The matter inside a neutron star is characterised by the relation between pressure and density, known as the neutron star equation of state. Equation of states of neutron stars are modelled by various theories in nuclear physics and quantum chromodynamics.

A neutron star in a binary system is deformed due to tidal forces of its companion, either a neutron star or a black hole. This effect is similar to what happens here on Earth when the moon’s gravity raises the ocean tides. Internal oscillations of the neutron star arise when the companion’s tidal force varies at a frequency close to the star’s characteristic frequency. This is like a bridge oscillating when a band marches at a pace matching its frequency. The amount of tidal deformation and the characteristic frequency depend on the equation of state of the neutron star matter. Any tidal response of the star leaves a distinct imprint on the gravitational waves emitted by the binary. Thus, gravitational waves will reveal unique information about the exotic interior of the neutron stars.

There are two types of tidal effects: gravitoelectic and gravitomagnetic. Gravitoelectic are leading order tidal effects while gravitomagnetic are next to leading order tidal effects. In this thesis, we modelled the gravitomagnetic tides for a binary neutron stars and their effect on the gravitational waves signal. We used this model to understand the effect of gravitomagnetic tides on measuring the equation of state of neutron stars using third-generation gravitational wave observatories such as Einstein Telescope and Cosmic Explorer.

Dark Charges
Most of the matter in the Universe is made of dark matter which cannot be directly observed. It is called ”dark” because it does not interact with light or other forms of electromagnetic radiation. Its presence can be inferred from its gravitational effects on visible matter, such as galaxies and clusters of galaxies. Over the years, many candidates of dark matter have been proposed, one of them being dark charges. These are reminiscent of electrons, but their charge-to-mass ratio is smaller. They can accumulate on binary black holes through various astrophysical processes. In this thesis, we explored the possibility of detecting dark charges using gravitational waves from binary black holes.
Estudio sobre la sustitución del término confiabilidad por el de representación fiel.
Authors: Avendaño Calderón Orlando
Published: September 2023

El Consejo de Normas Internacionales de Contabilidad, luego de intentar explicar el significado del término confiabilidad, tomó la decisión de sustituirlo por otro que mostrara más claramente su significado, por lo que propuso el de representación fiel. Esto generó malestar entre los profesionales de la contabilidad, quienes señalaban que ese Consejo podría haber explicado mejor el significado de confiabilidad sin sustituir el término. El presente trabajo de corte cualitativo pretende demostrar etimológicamente las diferencias de fondo entre estos términos. Entre los hallazgos más destacados se encuentra que el Consejo de Normas es consciente de que el término representación fiel podría no operar como un filtro eficiente ante las incertidumbres y que la tensión más destacada es la que surge entre la representación fiel y la relevancia.

Published: September 2023

Este artículo de investigación tiene por objetivo analizar los efectos derivados de la modificación del artículo 28 fracción XXX de la Ley del Impuesto Sobre la Renta vigente en Méjico. La investigación sigue el método descriptivo, con fuentes que dejan ver las realidades empíricas de la reforma, y el método deductivo para la argumentación sobre su legalidad derivada de la exclusión de la diferencia, en la naturaleza de las prestaciones laborales establecidas por la Ley Federal del Trabajo y las otorgadas voluntariamente por los patrones. Los resultados, soportados con datos estadísticos que reflejan los efectos económicos, detectan que la recaudación no se ha incrementado de manera integral y que el perjuicio a la base gravable de los patrones los ha motivado a implementar estrategias agresivas para  aminorar el efecto fiscal monetario.

Published: September 2023

Fujian province is located at the forefront of the South China continental margin, situated on the edge of the Circum-Pacific seismic belt, and it is one of the regions with the most active neotectonic and geothermal activities in Chinese mainland. To explore the geochemical signals of hot spring gases to tectonic activity and earthquakes, a collection of geothermal gas samples was collected from 29 locations in Fujian from January 2021 to December 2022 (many of which were multiply collected at several sites quarterly). The gas samples were tested for their gas composition, helium, neon, carbon isotopes, radon contents, and gas flow rates. The results show that the dominant component of the hot spring outgassing is N2, and the increase in CO2 content is often associated with the increasing 13C. The variation range of the helium isotope ratio (3He/4He) in the hot spring gases is between 0.06 and 2.20Ra, and Rc/Ra varies between 0.06 and 1.58, with peak values occurring at the intersections of deep faults. Radon contents range from 18 to 2000 Bq/L. Calculations revealed that the maximum proportion of mantle-derived helium is 30.2%, and the mantle-derived heat contribution ranges from 37.6% to 63.4%. These data indicate a significant mantle degassing process in Fujian, with a high degree of mantle-crust connectivity, and mantle-derived heat as the main source of geothermal activity in the area. Comparative analysis with regional seismic activity indicates that areas with relatively strong upwelling of deep fluids are the main regions of regional seismic activity, and seismic intensity is positively correlated with mantle-derived heat flow. Thus, deep thermal fluid actives are closely genetically correlated to regional seismic activity. Additionally, the correlation analysis with the Taiwan ML6.0 earthquake suggests that high 3He/4He, δ13CCO2 values of hot spring gas and gas flow velocity in Nancheng Hot Spring (QZ6) indicate significant short-term and imminent anomaly indications preceding ML6.0 earthquakes in the Taiwan region.

The Korean National Space Council recently released “Mars Exploration 2045” as part of its future strategic plan. The operations for a Mars explorer can be defined based on domestically available capabilities, such as ground operations, launch, in-space transport and deep space link. Accordingly, all of our exploration scenarios start from the Naro space center, and the pathway to Mars is optimized using an objective function that minimizes the required ∆V. In addition, the entire phase of Mars orbit insertion should remain in contact with our deep space antennas, a measure that is imposed as an operational constraint. In this study, a pattern search method is adopted, as it can handle a nonlinear problem without relying on the derivatives of the objective function, and optimal trajectories are generated on a daily basis for a 15-day launch period. The robustness of this direct search method is confirmed by consistently converged solutions showing, in particular, that the ascending departure requires slightly less ∆V than the descending departure on the order of 10 m/s. Subsequently, mass estimates are made for a Mars orbiter and a kick stage to determine if the desired ∆V is achievable with our eco-friendly in-space propulsion system when launched from our indigenous launch vehicle, KSLV-II.

The torsion spring of a carrier-based aircraft landing gear is a key component, which is normally manufactured out of AerMet100 ultra-high-strength steel. The takeoff and landing performance is greatly influenced by its bearing capacity and structural durability. To carry out the structure anti-fatigue design, it is necessary to investigate the influence of the spring structure features on its fatigue life, based on which the strain fatigue analysis and parameter optimization design of the torsion spring are executed. Through the finite element analysis conducted with ABAQUS, it was determined that there exists serious stress concentration in the relief groove. Based on the theory of strain fatigue, the fatigue life of the torsion spring was obtained, and the fracture position and lifecycle were consistent with the test results. A structure optimization platform based on a parametric method was established. Samples were selected through the DOE (design of experiment), and a surrogate model was established based on RBF (radial basis functions), followed by optimization using MIGA (multi-island genetic algorithms). With the parameter optimization of the relief groove, the structure was reconstituted and reanalyzed. From the simulation results, the peak strain was reduced by 30.7%, while the fatigue life was increased by 86.2% under the same loads and constraints. Moreover, laboratory tests were performed on the torsion spring after reconstruction, which showed that the fatigue life increases by 85.6% after optimization. The method presented in this paper can provide theoretical support and technical guidance for the application and structural optimization of ultra-high-strength steel structures.

Consumer preferences and attitudes toward genetically modified (GM) food have been widely studied, yet there is little research on the aspects of farmers and risk amplification. Based on both a field survey and an experiment conducted in villages in China’s eastern provinces of Shandong, Shanxi and Henan in 2021, we explore the impact of producers’ risk amplification and risk preferences on the acceptance of transgenic technology. Results show that only 37.3% of participants from the whole sample did not amplify the risk associated with GM products. In terms of regions, the percentages of participants in Henan, Shanxi and Shandong who amplified the risk associated with GM products were 65.3%, 62.4% and 60%, respectively. Moreover, the results of the economic experiment on risk preference indicate that over two-thirds of farmers proved to be risk-averse. Finally, full sample estimation results using ordered logit and Poisson models showed that risk amplification, relative risk aversion and risk perception all have negative impacts on producers’ response to GM plant seeds, including participants’ acceptance intention, purchasing intention and recommendation intention.
The Effect of Sulfur Carriers on Nitrogen Use Efficiency in Potatoes—A Case Study
Authors: Potarzycki Jarosław , Wendel Jakub
Published: September 2023

The use of sulfur is an important factor in potato production. At the beginning of this study, a hypothesis was put forward according to which sulfur carrier affects yield (TY) and nitrogen efficiency (EN). The three-year study was conducted in a two-factor system: (1) sulfur fertilization, SF (control—without S, elemental sulfur—S0, calcium sulfate—CS), and (2) nitrogen fertilization level, NF (0, 30, 60, 90, 120, and 150 kg N·ha−1). In addition to TY, the following EN indicators were analyzed: agronomical efficiency (EA), physiological efficiency (EPh), partial factor productivity (PFP), and recovery (R). For both sources of sulfur, an increase in TY was confirmed. After applying CS, the optimum for the maximum yield was 106 kg N·ha−1, while the application of S0 resulted in 134 kg N·ha−1. The impact of SF on the nitrogen economy decreased in the direction of EA = PFP > EF > R and depended on the sulfur carrier. A positive trend was found, associated with the increase in R under the influence of S0 and the clearly higher EPh after the application of CS. A particularly strong effect of CS on EA was evident in the range of lower nitrogen doses. The EN values depended on the meteorological conditions during the research years. The strongest variability was subject to EPh, which, as a result of SF, was significantly higher in relation to the control (without S) during the growing season, with an unfavorable distribution of precipitation. The application of CS reduced the unit nitrogen uptake (UU-N). Using path analysis, a direct relationship of Ca accumulation (controlled by N and S) with TY was demonstrated. The conducted research indicates a significant impact of sulfur fertilizers, related to TY and EN, especially visible under conditions of limited nitrogen supply.

Background: Serological diagnosis of COVID-19 is complex due to the emergence of different SARS-CoV-2 variants. Methods: 164 serum samples from (I) patients who recovered from COVID-19 (n = 62) as well as (II) vaccinated individuals (n = 52) and (III) vaccinated individuals who were infected with different SARS-CoV-2 variants after vaccination (n = 50) were included. All samples were tested using EIA (binding antibodies) and a virus neutralization test (VNT) using the Wuhan strain (NT antibodies). Group III was further tested with a VNT using the Alpha/Delta/Omicron strains. Results: The highest antibody index (AI) was observed in vaccinated individuals infected with COVID-19 (median AI = 50, IQR = 27–71) and the lowest in vaccinated individuals (median AI = 19, IQR = 8–48). Similarly, NT antibody titer was highest in vaccinated individuals infected with COVID-19 (median 128; IQR = 32–256) compared to vaccinated individuals (median 32, IQR = 4–128) and patients with COVID-19 (median 32, IQR = 8–64). The correlation between AI and NT titer was strongly positive in vaccinated individuals and moderately positive in patients with COVID-19. No significant correlation was observed in vaccinated individuals infected with COVID-19. In patients infected with Alpha and Delta, the lowest VNT positivity rate was for the Omicron variant (85.0%/83.3%). Patients infected with the Alpha variant showed the lowest NT titer for the Omicron variant (median titer 32) compared to the Wuhan/Delta variants (64/128). Patients infected with the Delta variant had the lowest NT titer to the Omicron variant (median 32), compared to the Wuhan/Alpha variants (64/128). Patients infected with the Omicron variant showed similar titers to the Delta/Wuhan variants (128) and higher to the Alpha variant (256). Conclusions: The cross-immunity to SARS-CoV-2 is lowest for the Omicron variant compared to the Alpha/Delta variants.

Published: September 2023

Although entity and relation joint extraction can obtain relational triples efficiently and accurately, there are a number of problems; for instance, the information between entity relations could be transferred better, entity extraction based on span is inefficient, and it is difficult to identify nested entities. In this paper, a joint entity and relation extraction model based on an Enhanced Span and Gate Mechanism (ESGM) is proposed to solve the above problems. We design a new span device to solve the problem of entity nesting and inefficiency. We use the pointer network method to predict the beginning and end of the span, and combine them through the one-to-many matching principle. A binary classification model is then trained to predict whether the span of the combination is the subject. In the object prediction stage, a gating unit is added to fuse the subject information with the sentence information and strengthen the information transfer between the entity and the relationship. Finally, the relationship is used as the mapping function to predict the tail entity related to the head entity. Our experimental results prove the effectiveness of this model. The precision of the proposed model reached 93.8% on the NYT dataset, which was 0.4% higher than that of the comparison model. Moreover, when the same experiment was conducted in a nested entity scenario, the accuracy of the proposed model was 4.4% higher than that of the comparison model.

Published: September 2023

Low-enthalpy geothermal systems are a promising source for renewable and clean energy for heating, cooling, and air conditioning residential buildings, contributing to the reduction in greenhouse gas emissions in line with the United Nations’ Sustainable Development Goals. Previous research emerged around the geothermal utilization of Sustainable Drainage Systems (SuDS) as multifunctional surfaces for stormwater control and energy saving, developing the water–energy nexus. However, these studies did not comprehensively considered the energy aspects for SuDS design, using non-standardized tests to measure the main thermal parameters. This research aims to address this gap by proposing a novel hybrid engineering procedure to study the thermal properties of SuDS layers and materials through experimental tests combined with steady-state and transient numerical simulations, using green swales operating under dry and wet conditions as a first case study for SuDS techniques. Novel materials incorporated into dry swales (expanded clay and construction and demolition waste) were tested. The results validated this new methodology, reporting an increase of 87% under dry conditions, and 51% under wet scenarios in the thermal insulation performance in comparison to standard materials. A better thermal performance of the systems can be achieved by approaching SuDS design from a holistic viewpoint that integrates energy aspects.
