Abstract. Aquifers harbor unique and highly adapted species, contributing to critical ecological processes and services. Understanding the key factors driving invertebrate assemblages in aquifers is a challenging task that, traditionally, has primarily been achieved in karst aquifers. This study aimed to uncover the factors influencing the composition and functionality of groundwater crustaceans in a volcanic aquifer of central Italy. We adopted a multidisciplinary approach, combining hydrogeology, geology, microbiology, and ecology, and found that the aquifer consisted of three adjacent groundwater bodies (GWBs) with different geochemistry (i.e., sulfate-depleted, K-rich and earth-alkaline) and microbial characteristics that remained consistent over the study period. We also unveiled significant differences in both the taxonomic and functional composition of groundwater crustaceans across the three GWBs and these patterns were consistent over time. Notably, the sulfate-depleted GWB lacked groundwater-obligate species, burrowers, stenothermal and moderately stenothermal species, while the K-rich and earth-alkaline GWBs had different species with similar functions related to locomotion, diet, and feeding habits. Stenothermal and moderately stenothermal crustacean species were only found in the K-rich GWB, which lacked epigean species. Major ions (SO4, Ca, NO3, and K), trace elements (B, Al, V, Se, and Ba), and microbial factors related to microbial cells with low nucleic acid (LNA cells) and carbohydrate catabolic profiles were the main descriptors of groundwater-obligate species abundances. Our findings revealed a significant correlation between the abundances of groundwater-obligate crustaceans and LNA cells, thus suggesting a selective feeding of groundwater invertebrate species on the aquatic microbial community. Our research emphasizes the need to consider diverse hydrogeological contexts within individual aquifers. Potential avenues for future research should further consider food web dynamics in groundwater communities and their impact on carbon and nutrient cycling.

Published: February 2024

Abstract. Since 2018, TROPOMI on-board Sentinel-5P provides unprecedented images of NO2 tropospheric columns at a relatively high spatial resolution with a daily revisit. This study aims at assessing the potential of the TROPOMI-PAL data to estimate the national to urban NOx emissions in France from 2019 to 2021, using the variational mode of the recent Community Inversion Framework coupled to the CHIMERE regional transport model at a spatial resolution of 10×10 km2. The seasonal to inter-annual variations of the NOx French emissions are analyzed. A specific attention is paid to the current capability to quantify strong anomalies in the NOx emissions at intra-annual scales such as the ones due to the COVID-19 pandemic, by using TROPOMI NO2 observations. The inversions lead to a decrease of the average emissions over 2019–2021 compared to 2016 of -3 % at national scale, which is lower than the decrease of -14 % between these years in the estimates of the French Technical Center for Air Pollution and Climate Change (CITEPA). This may be linked especially to the limited level of constraint brought by the TROPOMI data, due to the observation coverage and the ratio between the current level of errors in the observation and the chemistry-transport model, and the NO2 signal from the French anthropogenic sources. Focusing on local analysis and selecting the days during which the TROPOMI coverage is good over a specific local source, we compute the reductions in the NOx anthropogenic emission estimates by the inversions from spring 2019 to spring 2020. These reductions are particularly pronounced for the largest French urban areas (e.g., -26 % from April 2019 to April 2020 in the Paris urban area) and along major roadways, consistently with the reduction in the intensity of vehicle traffic reported during the lockdown period.
Effect of surficial geology mapping scale on modelled ground ice in Canadian Shield terrain
Authors: O'Neill H. Brendan , Wolfe Stephen A. , Duchesne Caroline , Parker Ryan J. H.
Published: February 2024

Abstract. Ground ice maps at circumpolar or hemispherical scales offer generalised depictions of abundance across broad geographic regions. In this paper, the effect of surficial geology mapping scale on modelled ground ice abundance is examined in the Slave Geological Province of the Canadian Shield, a region where the geological and glacial legacy has produced a landscape with significant variation in surface cover. Existing model routines from the Ground ice map of Canada (GIMC) were used with a 1:125 000 scale regional surficial geology compilation and compared to the national outputs, which are based on surficial geology at 1:5 000 000 scale. Overall, the regional scale modelling predicts much more ground ice than the GIMC due to greater representation of unconsolidated sediments in the region. Improved modelling accuracy is indicated by comparison of outputs to available empirical datasets due to improved representation of the inherent regional heterogeneity in surficial geology. The results demonstrate that the GIMC significantly underestimates the abundance and distribution of ground ice over Canadian Shield terrain. In areas with limited information on ground ice, regional-scale modelling may provide useful reconnaissance-level information to help guide field-based investigations required for planning infrastructure development. The use of current small-scale ground ice mapping in risk or cost assessments relating to permafrost thaw may significantly influence accuracy of outputs in areas like the Canadian Shield where surficial materials range from bedrock to frost-susceptible deposits over relatively short distances.
Energy-conserving physics for nonhydrostatic dynamics in mass coordinate models
Authors: Guba Oksana , Taylor Mark A. , Bosler Peter A. , Eldred Christopher , Lauritzen Peter H.
Published: February 2024

Abstract. Motivated by reducing errors in the energy budget related to enthalpy fluxes within the Energy Exascale Earth System Model (E3SM), we study several physics–dynamics coupling approaches. Using idealized physics, a moist rising bubble test case, and the E3SM's nonhydrostatic dynamical core, we consider unapproximated and approximated thermodynamics applied at constant pressure or constant volume. With the standard dynamics and physics time-split implementation, we describe how the constant-pressure and constant-volume approaches use different mechanisms to transform physics tendencies into dynamical motion and show that only the constant-volume approach is consistent with the underlying equations. Using time step convergence studies, we show that the two approaches both converge but to slightly different solutions. We reproduce the large inconsistencies between the energy flux internal to the model and the energy flux of precipitation when using approximate thermodynamics, which can only be removed by considering variable latent heats, both when computing the latent heating from phase change and when applying this heating to update the temperature. Finally, we show that in the nonhydrostatic case, for physics applied at constant pressure, the general relation that enthalpy is locally conserved no longer holds. In this case, the conserved quantity is enthalpy plus an additional term proportional to the difference between hydrostatic pressure and full pressure.
Improved flux linkage observer for position estimation of permanent magnet synchronous linear motor

Published: February 2024

Abstract. With the development of motor technology, sensorless control attracts more and more attention. In this paper, an improved flux linkage observer is proposed to overcome issues including inaccurate initial positions and sampling noise. The voltage and current models are combined, and a sliding-mode observer is designed based on the hybrid model to obtain the compensation voltage. Therefore, the estimated flux linkage after compensation can greatly resist the influence caused by inaccurate initial positions or sampling noise. Phase-locked loop technology is used to process the estimated flux linkage to get the stable estimated speed and position. The proposed scheme has a simple structure and only one parameter. It is easy to use and adjust in practice. The simulation and experimental results verify that the proposed algorithm is effective, and the estimated flux linkage and position is accurate with an inaccurate initial position.
Development and application of a mesh generator intended for unsteady vortex-lattice method simulations of wind turbines and wind farms
Authors: Roccia Bruno A. , Ceballos Luis R. , Verstraete Marcos L. , Gebhardt Cristian G.
Published: February 2024

Abstract. In the last decades, the unsteady vortex-lattice method (UVLM) has gained a lot of acceptance to study large onshore–offshore wind turbines (WTs). Furthermore, and due to the development of more powerful computers, parallelization strategies, and algorithms like the fast multipole method, it is possible to use vortex-based methods to analyze and simulate wind farms (WFs). However, UVLM-based solvers require structured meshes, which are generally very tedious to build using classical mesh generators, such as those utilized in the context of finite element methods (FEMs). Wind farm meshing is further complicated by the large number of design parameters associated with the wind turbine (coning angle, tilt angle, blade shape, etc.), farm layout, modeling of the terrain topography (for onshore WFs), and modeling of the sea level surface (for offshore WFs), which makes the use of FEM-oriented meshing tools almost inapplicable. In the literature there is a total absence of meshing tools when it comes to building aerodynamic grids of WTs and WFs to be used along with UVLM-based solvers. Therefore, in this work, we present a detailed description of the geometric modeling and computational implementation of an interactive UVLM-oriented mesh generator, named UVLMeshGen, developed entirely in MATLAB® and easily adaptable to GNU OCTAVE, for wind turbines and onshore–offshore wind farms. The meshing tool developed here consists of (i) a geometric processor in charge of designing and discretizing an entire wind farm and (ii) an independent module in charge of computing the kinematics for the entire WF. The output data provided by the UVLMeshGen consist of nodal coordinates and connectivity arrays, making it especially attractive and useful to be used by other flow potential solvers using vortices, sources and sinks, or dipoles/doublets, among others. The work is completed by providing a series of aerodynamic results related to WTs and WFs to show the capabilities of the mesh generator, without going into detailed discussions of wind turbine aerodynamics, which are not the focus of this paper.

Published: February 2024

The current study's objective is to ascertain students' awareness of cybercrime in the Chhattisgarh region. In the world we live in, technology is now required in every aspect of life from house hold work to running a multinational company and national security. Although technology makes life easier, there are risks associated with it, such as cybercrime (fraud, assault, bullying, sexual harassment, phishing). Students must understand that cyber security awareness is necessary to prevent any kind of cyber-crime. For understanding the cyber-awareness among Students of Chhattisgarh we collected data from Pt. Ravishankar Shukla University in Raipur. The cyber-crime awareness scale created by Dr. S. Rajasekar (2011) was used to test students' awareness of cybercrime using a questionnaire-based survey method. In this study, student demographic information (gender, location) is taken into account when measuring understanding of cyber-threats. . The hypothesis is tested using the t-test. The results show that although male and female students' knowledge of cybercrime is not statistically different, there is a significant difference between students in rural and urban locations.

Published: February 2024

This study examined ethical distribution and supply efficiency of petroleum products. It explored the contemporary ethical distribution practices adopted by petroleum marketers in extant literature; identified the current key performance indicators (KPIs) for supply efficiency in the petroleum industry; and explored the position of scholars on the influence of ethical distribution on supply efficiency of petroleum products, among other objectives. To that end, a systematic literature review methodology was adopted. Through a thorough search process supported by a set of stringent inclusion-exclusion criteria, 91 relevant articles were included in this review. The articles were analyzed using in-depth content analysis method augmented with descriptive statistics. Consequently, the major finding of the study revealed that the majority of extant scholarly studies reviewed supported the proposition that ethical distribution practices can have significant influences on supply efficiency of petroleum products in extant literature. It was also found that the contemporary ethical distribution practices adopted by petroleum marketers in extant literature can be grouped into 11 categories, while the current key performance indicators (KPIs) for supply efficiency in the petroleum industry can be grouped into 13 categories, among other findings. On that note, the study recommended the need for a robust regulatory and implementation framework that mandates and ensures that petroleum marketers consistently integrate ethical considerations into their distribution operations in order to improve supply efficiency of petroleum products.

Impact of Intense Modulation on Soliton Power Propagation across Optical Fiber and Optical Wireless Channels
Authors: S. Selva Nidhyananthan Et al.
Published: February 2024

The optical pulse generator model in Optisystem 20 is utilized to generate an optical soliton pulse. The performance evaluation of highly modulated soliton power transmission is carried out on both optical fiber and optical wireless communication channels. The evaluation considers a flow rate of 40 Gbps and a link distance, which is not specified in the provided context. Among the proposed modulation schemes, which include CPFSK, FSK, and PSK, CPFSK demonstrates superior performance for both communication channels. Increasing the number of bits per symbol enhances the bit error rate (BER) at the fiber or wireless channel, as received by the optical receiver, for different modulation schemes, except for the CPFSK scheme. Thus, it is evident that the CPFSK modulation scheme is more efficient and outperforms other modulation schemes for various communication channels. Hence, it is evident that the CPFSK modulation scheme exhibits superior efficiency and outperforms other modulation schemes for a variety of communication channels.

Updates on management of gliomas in the molecular age
Authors: Mohamed Ali Ahmed , Alshaibi Rakan , Faragalla Steven , Mohamed Youssef , Lucke-Wold Brandon
Published: February 2024

Gliomas are primary brain tumors derived from glial cells of the central nervous system, afflicting both adults and children with distinct characteristics and therapeutic challenges. Recent developments have ushered in novel clinical and molecular prognostic factors, reshaping treatment paradigms based on classification and grading, determined by histological attributes and cellular lineage. This review article delves into the diverse treatment modalities tailored to the specific grades and molecular classifications of gliomas that are currently being discussed and used clinically in the year 2023. For adults, the therapeutic triad typically consists of surgical resection, chemotherapy, and radiotherapy. In contrast, pediatric gliomas, due to their diversity, require a more tailored approach. Although complete tumor excision can be curative based on the location and grade of the glioma, certain non-resectable cases demand a chemotherapy approach usually involving, vincristine and carboplatin. Additionally, if surgery or chemotherapy strategies are unsuccessful, Vinblastine can be used. Despite recent advancements in treatment methodologies, there remains a need of exploration in the literature, particularly concerning the efficacy of treatment regimens for isocitrate dehydrogenase type mutant astrocytomas and fine-tuned therapeutic approaches tailored for pediatric cohorts. This review article explores into the therapeutic modalities employed for both adult and pediatric gliomas in the context of their molecular classification.
Population-based X-ray gastric cancer screening in Hiroshima prefecture, Japan
Authors: Vu Nhu Thi Hanh , Urabe Yuji , Quach Duc Trong , Oka Shiro , Hiyama Toru
Published: February 2024

BACKGROUND

X-ray gastric cancer (GC) screening has been shown to decrease mortality. Population-based X-ray GC screening has been performed in Hiroshima Prefecture, Japan, since 1983 but time trends and the efficacy of the method over 39 years have not been assessed.

AIM

To evaluate time trends and efficacy of population-based X-ray GC screening and identify challenges and suggested solutions for the future.

METHODS

This was a population-based retrospective study. The data were derived from aggregated data of the Hiroshima Regional Health Medical Promotion Organization, including the number and rate of participants and those requiring esophagogastroduodenoscopies (EGDs), the number and rate of participants diagnosed as having GC, and the positive predictive value of the abnormal findings detected by X-ray and confirmed by EGDs. The number and rate of esophageal cancers were also collected. Further, the cost of detecting one GC was evaluated.

RESULTS

The number of participants has decreased during the last four decades, from 39925 in 1983 to 12923 in 2021. The rate of those requiring EGDs decreased significantly in recent years (P < 0.001). The number of participants diagnosed as having GC has also declined, from 76 to 10 cases. However, the rate of cases diagnosed as GC among the participants remained around 0.1%. The positive predictive value increased significantly in recent years except during 1983-1991. The number and rate of accidentally detected esophageal cancers have risen recently, from 0% in 2008 to 0.02% in 2021, one-fifth of the diagnosis rate of GC. One GC diagnosis costs approximately 4200000 Japanese Yen (30000 United States Dollars) for the X-ray screenings and EGDs.

CONCLUSION

X-ray GC screening in Hiroshima has been efficient, but one challenge is the cost. Esophageal cancers may also need to be considered because they have gradually increased in recent years.

Religion, mental health, and terrorism: Public perception
Authors: Wildsmith Leah , Williams Thomas James Vaughan , Herbert Summer
Published: February 2024

Key digested message

The link between mental health and crime has been examined multiple times and the findings are inconsistent. The same notion applies to terrorism, however there is evidence that public perceptions are influenced by the defendant’s mental health. Due to the inconsistencies, this study examines whether religion, and mental health disorders, are factors for involvement in terrorism, whilst investigating the public perceptions. This pilot study utilised a sample of 156 participants through opportunity sampling (37 males & 118 females), with most participants being between the age of 18–24 years. The findings suggest that amongst other factors, the religion of the terrorist is a catalyst for the opinion of the public on whether he/she is guilty. Governments and related organisations, in cooperation with the media, should inform the public and increase awareness regarding the increased likelihood of falsely perceiving terrorists as mentally ill based on religion, and other background factors.

Authors: TÜRKOĞLU Ozan , BOZKURT Gökhan
Published: February 2024

The study aims to evaluate the effects of subcutaneously (SC) injected oily solution of melatonin crystal at different doses in 2-3 years, healthy, multiparous sheep during the anoestrus period on serum melatonin and prolactin levels, estrus occurrence, mating, conception, and pregnancy rates. The study group consists of 350 ewes. The ewes were divided into 5 groups: MEL10 (n=70, 10mg melatonin), MEL20 (n=70, 20mg melatonin), MEL40 (n=70, 40mg melatonin), placebo (n=70), and control (n=70) groups. The melatonin groups received SC injections of the oily melatonin solution 11 days before ram introduction. The placebo group received only the oily solution. The control group did not receive any treatment. Blood samples were collected from all groups before the melatonin injection and on the 11th day after the injection. The data showed that the melatonin level in the blood samples collected before and after the injection increased in the MEL10 (P:0.045) and MEL20 (P:0.0359) groups. Additionally, the prolactin level decreased in the second blood sample collected from all groups (P>0.05). Regarding reproductive parameters, the estrus rate in the MEL10, MEL20, MEL40, placebo, and control groups was 75.71%, 58.57%, 54.28%, 51.42%, and 52.85%, respectively. The mating rate was 61.42%, 57.14%, 52.85%, 48.57%, and 50% in the same groups, and the pregnancy rate was 60%, 52.85%, 42.85%, 41.42%, and 38.57%, respectively. The conception rate was determined as 97%, 92%, 81%, 85%, and 77% in the MEL10, MEL20, MEL40, placebo, and control groups, respectively. In conclusion, subcutaneous injection of melatonin at appropriate doses to sheep can indirectly simulate the breeding season, and stimulate heat. Additionally, it can increase pregnancy and conception rates. This method can considered a potential alternative to melatonin implants or different synchronization methods in the future.
Effect of ultrathin glass substrate on the stability of perovskite CH3NH3PbI3 layer
Authors: Ayad Aicha Aziza , Naas Abdelkrim , Selmi Noureddine , Meglali Omar
Published: February 2024

In this work, we investigated the effect of two different substrate types on the structural and optical characteristics of the CH3NH3PbI3 perovskite layer: soda-lime glass (SLG) and borosilicate glass (UTG). Subsequently, we examined the samples' stability by measuring their absorbance following 120 hours of exposure to the local ambient conditions in Djelfa, Algeria. The absence of OH groups in the UTG substrate as revealed by FTIR may be the reason for the notable impact of the UTG substrate over the SLG substrate on perovskite characteristics. This absence indicates that the inorganic element's influence on the perovskite significantly diminishes, and in this instance, the matrix endures for an extended period within the local metrological restrictions.
Systematicity and Skepticism
Authors: Segal Aaron
Published: February 2024

The fact that philosophy is systematic—that philosophical issues are thoroughly interconnected—was a commonplace among nineteenth century idealists, then neglected by analytic philosophers throughout much of the twentieth century, and has now finally started to get some renewed attention. But other than calling attention to the fact, few philosophers have tried to say what it consists in, or what its implications are.

I argue that the systematicity of philosophy has disastrous epistemological implications. In particular, it implies philosophical skepticism: philosophers are rationally prohibited from believing any philosophical thesis. The argument goes by way of a new principle that connects inquiry with what is rational to believe. I conclude with a discussion of the relationship between my argument and other, more well-trodden arguments for philosophical skepticism.
Echi letterari e pluralità di senso in una novella del Boccaccio
Authors: Franco Marcella Di
Published: February 2024

Il saggio si propone di indagare la novella Lisabetta da Messina di Giovanni Boccaccio, la quinta della IV giornata del Decameron. Ampiamente nota per il carattere tragico-elegiaco che la connota, è anche tra le più “resistenti” ad un'esegesi che esaurisca la sua profondità di senso e sciolga in via definitiva la natura stratificata che la ammanta. Il contributo si sofferma sulla funzione strutturale delle numerose ambiguità che attraversano il testo dal principio alla fine e intende svelare i meccanismi intrinseci su cui è costruita l'intera fabula attraverso le allusioni intertestuali. Oggetto di molteplici riletture critiche nel tempo, è proprio il suo carattere “sfuggente” ad avere conservato intatto il fascino del capolavoro novellistico di Boccaccio che scaturisce dalle sottili ambivalenze suscitate dai testi impliciti sottesi, dai numerosi paratesti inglobati o allusivamente richiamati, soprattutto i classici della tradizione greco-latina o i rimandi medievali coevi e anteriori. Il potere fortemente generativo dell'ambiguità strutturale del testo in sé moltiplica il gioco delle diverse interpretazioni possibili che nei secoli hanno offerto un aggancio testuale anche agli scrittori posteriori. Nella sua peculiare anamorfosi consiste pertanto la sua capacità di resistere ad una decifrazione appagante e onnicomprensiva, nonostante i vari approcci sociologici, storici, comparativi, linguistici, semiologici e psicoanalitici proposti, ognuno dei quali svela parzialmente la verità, ma senza mai illuminare esaustivamente i sensi ultimi di una novella esemplare.
L'Universo femminile di Maria Messina
Authors: Privitera Daniela
Published: February 2024

La presente proposta di lettura è dedicata alla figura di Maria Messina, scrittrice siciliana verista ingiustamente caduta nell'oblio e rivalutata negli anni ‘80 da Leonardo Sciascia. Dopo un'iniziale adesione ai modelli del verismo verghiano, la narrativa della Messina si caratterizza per una sua originalità legata all'analisi delle numerose figure femminili che popolano le sue opere. Il ritratto che ne emerge è quello di un'estrema condizione di subalternità femminile asservita all'universo fallocentrico della cultura dominante del potere maschile. L'analisi condotta nel presente lavoro si sofferma su alcune delle protagoniste femminili della raccolta Ragazze siciliane (1921) e mira a rilevare, attraverso un'interpretazione tematica ed onomastica dei testi, la presenza di un “protofemminismo” ante litteram per mezzo del quale la scrittrice ha coraggiosamente affrontato tematiche ritenute “scottanti” per il periodo storico, quali l'alterità e la differenza.
Educating the Younger Generation of Polish Female Refugees in Postwar Britain
Authors: Błaszczyk Agata
Published: February 2024

This study explores the education of young Polish female refugees in postwar Britain, and the implications of the establishment of the Committee for the Education of Poles, a body brought into being on April 1, 1947, as a consequence of the passage of the Polish Resettlement Bill in March 1947 (the first ever British legislation dealing with mass immigration). It examines the newly introduced grammar schools for girls, the challenges raised for these new educational establishments, and the strategies introduced by the British authorities in order to cope with the growing numbers of Polish adolescents entering the country after World War II. Based on archival records and supported by oral interviews, the sample case studies presented herein highlight one way in which the young Polish community was rehabilitated in exile at the start of their path towards civic integration. They highlight the key importance of education to that pathway. The studies presented here provide an insight into the experiences of, and challenges faced by, young Polish women during the Process of their education and resettlement. Thanks to extant school reports, it has been possible to ascertain not only the practical and financial problems that impacted the schools presented in the paper, which operated under the auspices of the Committee for the Education of Poles, but also their slow, but steady improvement over time. The paper provides clear evidence that it was thanks to the Committee that a significant proportion of the younger generation of Poles managed to acquire the qualifications needed to secure their first jobs and ultimately a career in industry or business and so play a useful part in the economic life of Great Britain and her overseas territories.

A Review of 23-Year Corpus-based Research on Writing English Teaching in China from 2001-2023
Authors: Lin Jiaxin , Zuo Yi
Published: February 2024

This study is based on 145 core journal papers collected by China National Knowledge Infrastructure (CNKI) from 2001 to 2023, and explores the progress and shortcomings of English writing teaching research based on English writing corpora in China over the past 20 years. The results show that: (1) In terms of overall trend, this type of research has experienced rapid growth since 2001 and reached its peak from 2009 to 2016, before gradually decreasing. (2) In terms of research subjects, college students and graduate students make up the vast majority, with less involvement of middle school students. (3) In terms of research content, it mainly involves the construction, application, investigation, comparison, and review of corpora, as well as semantic rhyme, vocabulary, and chunks in English writing based on corpora. However, in providing teachers with more comprehensive training on corpus application, and combining artificial intelligence technology with corpus application to develop intelligent auxiliary writing tools, current research is very limited. The above findings have implications for the design of writing corpora and related teaching research.
