Authors: Zhang Tao , Bian Shaofeng , Ji Bing , Li Wanqiu , Zong Jingwen , Yuan Jiajia
Published: June 2024

The accuracy of estimating changes in terrestrial water storage (TWS) using Gravity Recovery and Climate Experiment (GRACE) level-2 products is limited by the leakage effect resulting from post-processing and the weak signal magnitude in adjacent areas. The TWS anomaly from 2003 to 2016 in the Dnieper River basin, with characteristics of medium scale and an adjacent weak TWS anomaly area, are estimated in this work. Two categories of leakage error repair approaches (including forward modeling, data-driven, single, and multiple scaling factor approaches) are employed. Root mean square error (RMSE) and Nash–Sutcliffe Efficiency (NSE) are used to evaluate the efficiency of approaches. The TWS anomaly inverted by the forward modeling approach (FM) is more accurate in terms of RMSE 3.04 and NSE 0.796. We compared single and multiple scaling approaches for the TWS anomaly and found that leakage signals mostly come from semi-annual terms. From the recovered results demonstrated in the spatial domain, the South of Dnieper River basin is more sensitive to the leakage effect because of it is adjacent to a weak hydrological signal region near the Black Sea. Further, comprehensive climate insights and physical mechanisms behind the TWS anomaly were confirmed. The temperate continental climate of this river basin is shown according to the variation in TWS anomaly in the spatial domain. Snowmelt plays a significant role in the TWS anomaly of the Dnieper River basin, following the precipitation record and the 14-year temperature spatial distribution for February. We compared single and multiple scaling approaches for the TWS anomaly and found that leakage signals mostly come from semi-annual terms.

Potentiometric titration in a fast and simultaneously high-resolution modality was proposed for the identification and quantification of protolytic groups of variable strength at the surface of primary soil particles. The method is implemented by titrimetric data processing as multicomponent spectra (pKa spectrotitrimetry). Due to the high resolution, the error of acidity-constant assessment (3–5%) is lower, compared to existing approaches; due to the fast titration, the effect of soil hydrolysis is minimized. The soil profiles for acidic Retisols (podzolic soils)—under a spruce crown and in the intercrown space—were studied. These soils, which have similar bulk properties and genesis but developed under different plant covers, were distinguished by pKa spectral features at 4–5; 5.5–6.5; 6.5–8.5; 7.5–8.5; and 9–10, as well as total group concentrations. Differences in acidic and basic-group distribution (carboxyl groups, amorphous aluminosilicates, carbonate species, amino groups, soluble (poly)phenolic compounds, phospholipids) and Al and Fe complex compounds within the same soil profiles and between two Retisols were found and quantified. The acidity constants and group concentrations found by pKa spectrotitrimetry were compared with conventional soil-composition indicators (total organic carbon, oxalate-soluble Fe and Al, and phosphorus), using principal component analysis. The main correlations are between the concentrations of oxalate-soluble Al and groups with pKa values of 5.0–6.5 and 8.5; oxalate-soluble Fe and pKa values of 9.0–10.0; and P2O5 and pKa values of 4.0–6.0 and 6.5–8.5. The method provides a set of major acidity values without a priori information on a soil sample and can be used for screening and identifying similar soils.

Published: June 2024

Conventional biodiesel manufacturing uses alcohol as an acyl acceptor, resulting in glycerol as a side product. The increased demand for biodiesel has led to the production of a substantial surplus of glycerol, exceeding the market need. Consequently, glycerol is now being regarded as a byproduct, and in some cases, even as waste. The present study aims to suggest an economically viable and ecologically friendly approach for maintaining the viability of the biodiesel sector. This involves generating an alternative byproduct of higher value, rather than glycerol. Triacetin is produced through the interesterification of triglycerides with methyl acetate, and is a beneficial ingredient to biodiesel, reducing the need for extensive product separation. The primary objective of this research is to improve the interesterification reaction by optimising process parameters to maximise biodiesel production while using sulphuric acid as an economically viable catalyst. The study utilised the Box–Behnken design (BBD) to investigate the influence of various process variables on biodiesel yield, such as reaction time, methyl acetate to oil molar ratio, and catalyst concentration. An optimisation study using Response Surface Methodology (RSM) focused on key process reaction parameters, including the methyl acetate to oil (MA:O) molar ratio, catalyst concentration, and residence time. The best conditions produced a biodiesel blend with a 142% yield at a 12:1 MA:O molar ratio, with 0.1 wt% of catalyst loading within 1.7 h. The established technique is deemed to be undeniably effective, resulting in an efficient biodiesel production process.

The increasing commercial, industrial, and medical applications of plastics cannot be halted during the coming years. Microplastics are a new class of plastic pollutants which have emerged as escalating environmental threats. The persistence, effects, and removal of MPs present in soil, water, and numerous organisms have become an important research field. However, atmospheric microplastics (AMPs), which are subcategorized into deposited and suspended, remain largely unexplored. This review presents the recent developments and challenges involved in fully understanding suspended and deposited AMPs. The evaluation of indoor suspended MP fibers needs to be critically investigated to understand their implications for human health. Furthermore, the transportation of AMPs to isolated locations, such as cryospheric regions, requires immediate attention. The major challenges associated with AMPs, which have hindered advancement in this field, are inconsistency in the available data, limited knowledge, and the lack of standardized methodologies for the sampling and characterization techniques of AMPs.
Interferon-Regulated Expression of Cellular Splicing Factors Modulates Multiple Levels of HIV-1 Gene Expression and Replication

Published: June 2024

Type I interferons (IFN-Is) are pivotal in innate immunity against human immunodeficiency virus I (HIV-1) by eliciting the expression of IFN-stimulated genes (ISGs), which encompass potent host restriction factors. While ISGs restrict the viral replication within the host cell by targeting various stages of the viral life cycle, the lesser-known IFN-repressed genes (IRepGs), including RNA-binding proteins (RBPs), affect the viral replication by altering the expression of the host dependency factors that are essential for efficient HIV-1 gene expression. Both the host restriction and dependency factors determine the viral replication efficiency; however, the understanding of the IRepGs implicated in HIV-1 infection remains greatly limited at present. This review provides a comprehensive overview of the current understanding regarding the impact of the RNA-binding protein families, specifically the two families of splicing-associated proteins SRSF and hnRNP, on HIV-1 gene expression and viral replication. Since the recent findings show specifically that SRSF1 and hnRNP A0 are regulated by IFN-I in various cell lines and primary cells, including intestinal lamina propria mononuclear cells (LPMCs) and peripheral blood mononuclear cells (PBMCs), we particularly discuss their role in the context of the innate immunity affecting HIV-1 replication.
A Coiled-Coil Nucleotide-Binding Domain Leucine-Rich Repeat Receptor Gene MeRPPL1 Plays a Role in the Replication of a Geminivirus in Cassava
Authors: Ramulifho Elelwani , Rey Chrissie
Published: June 2024

Disease resistance gene (R gene)-encoded nucleotide-binding leucine-rich repeat proteins (NLRs) are critical players in plant host defence mechanisms because of their role as receptors that recognise pathogen effectors and trigger plant effector-triggered immunity (ETI). This study aimed to determine the putative role of a cassava coiled-coil (CC)-NLR (CNL) gene MeRPPL1 (Manes.12G091600) (single allele) located on chromosome 12 in the tolerance or susceptibility to South African cassava mosaic virus (SACMV), one of the causal agents of cassava mosaic disease (CMD). A transient protoplast system was used to knock down the expression of MeRPPL1 by clustered regularly interspaced short palindromic repeats-CRISPR-associated protein 9 (CRISPR-Cas9). The MeRPPL1-targeting CRISPR vectors and/or SACMV DNA A and DNA B infectious clones were used to transfect protoplasts isolated from leaf mesophyll cells from the SACMV-tolerant cassava (Manihot esculenta) cultivar TME3. The CRISPR/Cas9 silencing vector significantly reduced MeRPPL1 expression in protoplasts whether with or without SACMV co-infection. Notably, SACMV DNA A replication was higher in protoplasts with lower MeRPPL1 expression levels than in non-silenced protoplasts. Mutagenesis studies revealed that protoplast co-transfection with CRISPR-MeRPPL1 silencing vector + SACMV and transfection with only SACMV induced nucleotide substitution mutations that led to altered amino acids in the highly conserved MHD motif of the MeRPPL1-translated polypeptide. This may abolish or alter the regulatory role of the MHD motif in controlling R protein activity and could contribute to the increase in SACMV-DNA A accumulation observed in MeRPPL1-silenced protoplasts. The results herein demonstrate for the first time a role for a CNL gene in tolerance to a geminivirus in TME3.
Development of Robust Freeze-Drying Process for Long-Term Stability of rVSV-SARS-CoV-2 Vaccine

Published: June 2024

The thermostability of vaccines, particularly enveloped viral vectored vaccines, remains a challenge to their delivery wherever needed. The freeze-drying of viral vectored vaccines is a promising approach but remains challenging due to the water removal process from the outer and inner parts of the virus. In the case of enveloped viruses, freeze-drying induces increased stress on the envelope, which often leads to the inactivation of the virus. In this study, we designed a method to freeze-dry a recombinant vesicular stomatitis virus (VSV) expressing the SARS-CoV-2 spike glycoprotein. Since the envelope of VSV is composed of 50% lipids and 50% protein, the formulation study focused on both the protein and lipid portions of the vector. Formulations were prepared primarily using sucrose, trehalose, and sorbitol as cryoprotectants; mannitol as a lyoprotectant; and histidine as a buffer. Initially, the infectivity of rVSV-SARS-CoV-2 and the cake stability were investigated at different final moisture content levels. High recovery of the infectious viral titer (~0.5 to 1 log loss) was found at 3–6% moisture content, with no deterioration in the freeze-dried cakes. To further minimize infectious viral titer loss, the composition and concentration of the excipients were studied. An increase from 5 to 10% in both the cryoprotectants and lyoprotectant, together with the addition of 0.5% gelatin, resulted in the improved recovery of the infectious virus titer and stable cake formation. Moreover, the secondary drying temperature of the freeze-drying process showed a significant impact on the infectivity of rVSV-SARS-CoV-2. The infectivity of the vector declined drastically when the temperature was raised above 20 °C. Throughout a long-term stability study, formulations containing 10% sugar (sucrose/trehalose), 10% mannitol, 0.5% gelatin, and 10 mM histidine showed satisfactory stability for six months at 2–8 °C. The development of this freeze-drying process and the optimized formulation minimize the need for a costly cold chain distribution system.

The COVID-19 pandemic, caused by SARS-CoV-2, has posed significant health challenges worldwide. While children generally experience less severe illness compared to adults, pneumonia remains a substantial risk, particularly for those under five years old. This study examines the clinical characteristics and treatment outcomes of pediatric COVID-19 pneumonia patients treated with favipiravir in Thailand, aiming to identify associated factors for pneumonia. A retrospective review was performed on pediatric patients aged 1 month to 18 years hospitalized with COVID-19 at Srinagarind Hospital, Khon Kaen University, from 13 January 2020 to 15 November 2021. Data on demographics, clinical symptoms, treatment, and outcomes were collected, and logistic regression analysis was used to identify factors associated with pneumonia. Among 349 hospitalized children, the median age was 8 years, with 51.9% being male. Symptoms included a fever (100%), a cough (74.2%), and a rash (24.9%). COVID-19 pneumonia was diagnosed in 54.7% of the children. Favipiravir was administered as the standard treatment, showing mild adverse effects, including a rash (4.3%) and nausea (2.8%). Monocytosis was significantly associated with COVID-19 pneumonia (aOR 30.85, 95% CI: 9.03–105.41, p < 0.001), with an ROC curve area of 0.77 (95% CI: 0.71–0.83). Pediatric COVID-19 patients typically exhibit mild-to-moderate symptoms, with pneumonia being common in the early pandemic phase. Monocytosis is a significant factor associated with COVID-19 pneumonia. Favipiravir demonstrated mild adverse effects. Further studies are needed to validate these findings across different settings and phases of the pandemic.

The aim of this study was to investigate the effects of administrating Remdesivir at the acute COVID-19 phase on developing post-COVID symptoms in previously hospitalized COVID-19 survivors by controlling factors such as age, sex, body mass index, and vaccination status. A case-control study was performed. Hospitalized COVID-19 survivors who had received intravenous Remdesivir during the acute phase (n = 216) were matched by age, sex, body mass index, and vaccination status with survivors who did not receive antiviral treatment (n = 216). Participants were asked to self-report the presence of any post-COVID symptom (defined as a symptom that started no later than three months after infection) and whether the symptom persisted at the time of study (mean: 18.4, SD: 0.8 months). Anxiety levels (HADS-A), depressive symptoms (HADS-D), sleep quality (PSQI), and severity/disability (FIC) were also compared. The multivariate analysis revealed that administration of Remdesivir at the acute COVID-19 phase was a protective factor for long-term COVID development (OR0.401, 95%CI 0.256–0.628) and specifically for the following post-COVID symptoms: fatigue (OR0.399, 95%CI 0.270–0.590), pain (OR0.368, 95% CI 0.248–0.548), dyspnea at rest (OR0.580, 95%CI 0.361–0.933), concentration loss (OR0.368, 95%CI 0.151–0.901), memory loss (OR0.399, 95%CI 0.270–0.590), hair loss (OR0.103, 95%CI 0.052–0.207), and skin rashes (OR0.037, 95%CI 0.005–0.278). This study supports the potential protective role of intravenous administration of Remdesivir during the COVID-19 acute phase for long-lasting post-COVID symptoms in previously hospitalized COVID-19 survivors.

Human alphaherpesvirus 1 (HSV-1) is a significantly widespread viral pathogen causing recurrent infections that are currently incurable despite available treatment protocols. Studies have highlighted the potential of antimicrobial peptides sourced from Vespula lewisii venom, particularly those belonging to the mastoparan family, as effective against HSV-1. This study aimed to demonstrate the antiviral properties of mastoparans, including mastoparan-L [I5, R8], mastoparan-MO, and [I5, R8] mastoparan, against HSV-1. Initially, Vero cell viability was assessed in the presence of these peptides, followed by the determination of antiviral activity, mechanism of action, and dose-response curves through plaque assays. Structural analyses via circular dichroism and nuclear magnetic resonance were conducted, along with evaluating membrane fluidity changes induced by [I5, R8] mastoparan using fluorescence-labeled lipid vesicles. Cytotoxic assays revealed high cell viability (>80%) at concentrations of 200 µg/mL for mastoparan-L and mastoparan-MO and 50 µg/mL for [I5, R8] mastoparan. Mastoparan-MO and [I5, R8] mastoparan exhibited over 80% HSV-1 inhibition, with up to 99% viral replication inhibition, particularly in the early infection stages. Structural analysis indicated an α-helical structure for [I5, R8] mastoparan, suggesting effective viral particle disruption before cell attachment. Mastoparans present promising prospects for HSV-1 infection control, although further investigation into their mechanisms is warranted.

Multisystem Inflammatory Syndrome in Children (MIS-C) is a potentially life-threatening complication of COVID-19. The pathophysiological mechanisms leading to severe disease are poorly understood. This study leveraged clinical samples from a well-characterized cohort of children hospitalized with COVID-19 or MIS-C to compare immune-mediated biomarkers. Our objective was to identify selected immune molecules that could explain, in part, why certain SARS-CoV-2-infected children developed MIS-C. We hypothesized that type-2 helper T cell-mediated inflammation can elicit autoantibodies, which may account for some of the differences observed between the moderate–severe COVID-19 (COVID+) and MIS-C cohort. We enumerated blood leukocytes and measured levels of selected serum cytokines, chemokines, antibodies to COVID-19 antigens, and autoantibodies in children presenting to an academic medical center in Connecticut, United States. The neutrophil/lymphocyte and eosinophil/lymphocyte ratios were significantly higher in those in the MIS-C versus COVID+ cohort. IgM and IgA, but not IgG antibodies to SARS-CoV-2 receptor binding domain were significantly higher in the MIS-C cohort than the COVID+ cohort. The serum levels of certain type-2 cytokines (interleukin (IL)-4, IL-5, IL-6, IL-8, IL-10, IL-13, and IL-33) were significantly higher in children with MIS-C compared to the COVID+ and SARS-CoV-2-negative cohorts. IgG autoantibodies to brain antigens and pentraxin were higher in children with MIS-C compared to SARS-CoV-19-negative controls, and children with MIS-C had higher levels of IgG anti-contactin-associated protein-like 2 (caspr2) compared to the COVID+ and SARS-CoV-19-negative controls. We speculate that autoimmune responses in certain COVID-19 patients may induce pathophysiological changes that lead to MIS-C. The triggers of autoimmunity and factors accounting for type-2 inflammation require further investigation.
Message Effectiveness of Fear Appeals in Vaccination Communication Campaigns: A Systematic Review
Authors: Limbu Yam B. , Huhmann Bruce A.
Published: June 2024

This systematic review of 54 cross-disciplinary peer-reviewed causal empirical studies helps public health officials, researchers, and healthcare professionals better comprehend the effects of fear appeals in vaccine promotional campaigns on message processing, persuasion, vaccination attitudes, and vaccination intentions. This review documents inconsistent findings across studies, which it attempts to clarify by considering differences in research designs, sample populations, and outcomes measured. In general, we find that fear appeals increase risk perceptions, message involvement, and vaccination attitudes. However, fear appeals have less influence on vaccination intentions, especially among female and general adult populations or populations from the U.S. and other Western cultures. On the other hand, the effect of fear appeals on vaccination intentions is stronger among student populations and those from China (People’s Republic of China and Hong Kong) and other non-Western cultures. Also, fear appeals are less persuasive when promoting COVID-19 vaccines and boosters than they are for other vaccines (e.g., HPV, influenza, MMR). Future research should compare fear appeal effectiveness in messages across vaccines or when combined with other executional elements, such as the endorser or type of evidence provided. Finally, future studies should explore other methodological approaches and measure underexplored message outcomes, such as vaccine uptake behavior, in more naturalistic settings.

Understanding the oceanic carbon cycle, particularly in the Arctic regions, is crucial for addressing climate change. However, significant research gaps persist, especially regarding climate effects on the oceanic carbon cycle in these regions. This review systematically explores Arctic-related research, focusing on mechanisms, regulatory frameworks, and modelling approaches in the oceanic carbon cycle, carbon sink, climate change impact, and maritime shipping. The findings highlight the Arctic’s limited observer presence and high operational costs, hindering the data availability and studies on carbon-cycle changes. This underscores the need to integrate real-time Arctic Ocean monitoring data. Carbon sink research urgently requires direct methods to measure anthropogenic carbon uptake and address uncertainties in air–ocean carbon fluxes due to sea ice melting. Unlike terrestrial carbon cycling research, carbon-cycle studies in the oceans, which are essential for absorbing anthropogenic emissions, receive insufficient attention, especially in the Arctic regions. Numerous policies often fall short in achieving effective mitigation, frequently depending on voluntary or market-based approaches. Analyzing carbon-cycle and sink models has uncovered limitations, primarily due to their global perspective, hampering in-depth assessments of climate change effects on the Arctic regions. To pave the way for future research, enhancing Arctic Ocean climate data availability is recommended, as well as fostering international cooperation in carbon-cycle research, enforcing carbon policies, and improving regional modelling in the Arctic Ocean.

Published: June 2024

Nitrate contamination in groundwater is a global concern due to its widespread presence and consequential social, environmental, and economic ramifications. This study investigates the efficacy of biological denitrification in a humid tropical setting, utilizing corn cob in batch and column tests to assess nitrate removal under varying conditions. Batch tests demonstrated the nitrate removal efficiencies of 93.14%, 91.58%, 90.77%, and 98.74% for initial concentrations of 22.18 ± 2.82 mg/L, 27.3 mg/L, 69.1 ± 1.2 mg/L and 115.08 ± 1.88 mg/L, respectively. In the column test, the removal efficiency was 99.86%, 87.13%, and 74%, and the denitrification rate was 32.82, 53.43, and 83.53 mg NO3−-N/L d, for a hydraulic retention time (HRT) of 24 h, 16 h, and 7 h, respectively. Predominantly, nitrate removal occurred via biological denitrification, particularly favoring a 24 h HRT. The corn cob effectively removed high nitrate concentrations of up to 115 mg NO3−-N/L. Scanning electron microscopy and Fourier transform infrared spectroscopy revealed surface characteristic changes of the carbon source pre- and post-denitrification. This research sheds light on the potential of biological denitrification using corn cob in humid tropical environments, offering a promising avenue for addressing nitrate contamination challenges in groundwater systems.

Phosphorus (P) is a critical element for life, and wastewater treatment systems can be strategic points for its recovery, thereby avoiding eutrophication pollution in nature. The aim of this research was to investigate P recovery via struvite, namely in terms of the influence of operating parameters, coexisting interfering ions, and seeding. This paper focuses on synthetic solutions, although an assessment was performed on wastewater. The results of the assessment indicated that, in the synthetic solution, the minimum concentration for struvite precipitation is about 30 mg P/L, and that the Mg/P molar ratio of 1 promotes P removal efficiency with less contribution from other minerals. In order to assess the results in terms of real-world scenarios, the influence of coexisting ions (calcium and sodium) was investigated. Calcium was shown to have the greatest impact on the process, as 80% was removed for an initial concentration of 200 mg Ca/L. Indeed, these experiments generated an amorphous precipitate that did not contain struvite. The utilization of biomass ash (size < 63 µm) as seeding in crystallization increased the P removal efficiency compared to the sample without seed and helped to control the pH. The precipitation experiments with wastewater demonstrated good P removal efficiencies (over 90%) but indicated a reduction in the purity of the final product (struvite was a minor crystalline phase identified in XRD—15%wt).

An inventory of the biological diversity of specially protected natural areas is a necessary basis for understanding the patterns of formation and functioning of reference natural complexes, planning work on their monitoring and environmental protection measures, and also serves the objectives of educational work. Fishes of the Yenisei river basin has been relatively well studied, but there is no data about ichthyofauna of the water bodies of the Shushensky Bor National Park (located in the south of the Krasnoyarsk Territory). During this study in lake Butakovo, which is part of the lake-marsh massif “Shushensky Marshes“ on the territory of the Perovsky cluster of the Shushensky Bor National Park, 4 species of fish were noted. Of these, the prussian carp Carassius gibelio (Bloch, 1782), the crucian carp C. carassius (Linnaeus, 1758) and the tench Tinca tinca (Linnaeus, 1758) are typical fishes of the Minusinsk Hollow. The belica Leucaspius delineatus (Heckel, 1843) is alien species, relatively recently recorded in the Yenisei river basin. Finding of the belica in lake Butakovo is currently the southernmost recorded habitat of this invasive species in the Yenisei river basin. In the structure of the fish community in lake Butakovo is dominated by C. gibelio. It is super dominant both in numbers and in biomass. The C. carassius should be classified as the dominant species, and the T. tinca should be classified as common. The L. delineatus, which is 5% in number, due to its small size forms only 1% of the ichthyomass, while, according to the classification of Tereshchenko and Nadirov, it should be classified as a common species.

Published: June 2024

Background

GPs and mental health nurse practitioners (MHNPs) often feel ill equipped to provide mental health (MH) care to people with mild intellectual disabilities (MID). This is worrying, as insufficient primary MH care may lead to more severe or chronic problems. To improve primary MH care for this patient group, account must be taken of the experiences and needs of GPs and MHNPs providing the care.

Aim

To explore GPs’ and MHNPs’ experiences, needs, and recommendations for improvement regarding primary MH care for adults with MID.

Design & setting

A qualitative study was undertaken using focus groups with GPs and MHNPs in the Netherlands.

Method

The focus groups were guided by topics based on an interview study with adults with MID receiving primary MH care. Transcripts were analysed by thematic analysis.

Results

Four focus groups, with 19 GPs and nine MHNPs, revealed four themes describing the needs and perceived complexity involved in providing MH care to patients with both MID and MH problems: (1) GPs’ and MHNPs’ struggles with adapting to challenging patient characteristics; (2) importance and difficulties of establishing a good doctor–patient relationship; (3) facilitating and hampering roles of the patient’s network; and (4) GPs’ and MHNPs’ challenges to provide care in the healthcare chain.

Conclusion

GPs and MHNPs often experience providing care and support to this patient group as burdensome. It is important to consider the MID throughout the MH trajectory, to invest in a strong doctor–patient relationship, and to establish a stable, sustainable network and coordinated collaborative care around the patient.

Authors: Hanafi Murtala
Published: June 2024

This paper economic rights of women under the Sokoto Caliphate, a lesson for women of contemporary Nigeria, discusses the various economic activities which women engaged themselves in Sokoto without interference from the men. Rights of women have occupied prominent place in the scheme of Islamic affairs from the inception of Islamic message. It is no longer a history to state that the Prophet (S.A.W) upgraded the status of women from what is used to be and made them equal with the male gender throughout the period of his Prophet hood. Part of the rights accorded women in the early days of Islam includes economic right. This paper highlight some of the entrepreneurship which women engaged in and also challenges which they face in the caliphate before now. It also discussed are the rights enjoy by Muslim women in Sokoto.

Published: June 2024

The article is devoted to the systematization of financial indicators for assessing the level of countries economic security and defining the role and importance of indicators in the system of economic security monitoring. It is determined that the indicator approach is the most common in terms of assessing and monitoring the level of financial security and allows for effective management of financial risks. In this case, indicators act as measures of the degree of stability, reliability and efficiency of the country's economic system. The authors prove that indicators form the methodological basis for monitoring the level and status of economic and financial security. The indicators are classified according to security subsystems and take into account the peculiarities of their formation. The authors analyze the approaches to systematization of financial indicators used in Ukrainian practice, in particular, within the framework of the official methodology for assessing the level of Ukraine’s economic security, as well as within the methodology for assessing the level of financial stability and sustainability used by the National Bank of Ukraine. Among the approaches developed and implemented at the international level, the author examines the IMF Financial Sustainability Indicators System, the IMF and World Bank Debt Sustainability Framework, The World Bank Global Findex Database, and The system of Financial Indicators for Socioeconomic Development of The World Bank (Open Data). Keywords: financial indicator, economic security, financial security, security monitoring, resilience.
Functional expression of parcelats in Ivan Franco`s idiostyle

The article is devoted to the study of parcelat, which is one of the means of expressive syntax. The use of parcellation is characteristic feature of artistic and conversational styles, which demonstrates the combination of various syntactic forms of expression dictated by communicative requirements. Parcelat is the result of the segmentation of a sentence as a complete syntactic and intonation-content structure into several elements (basic part and segment) in order to actualize individual fragments of the message. In the context of the theory of actual articulation, the main part (core) of the parcelat occupies the thematic position, and the segment (parcel) is an expression of the rheme. The lack of linguistic works dedicated to the study of parcelat in the artistic heritage of Ivan Franko arouses scientific interest in studying the peculiarities of the functioning of parcelat in the writer's artistic works and determining their tasks in achieving a perlocutionary effect on the reader. The purpose of the scientific article is to study the peculiarities of the functioning of parcelat within a simple sentence based on the materials of Ivan Franko's literary works ("Petrii and Dovbuschuku" (1 ed.), "Borislav laughs", "Cross paths", "Petrii and Dovbuschuku" (2 ed.)), belonging to different periods of the writer's creativity. Parceled homogeneous predicates are the most used within a simple sentence, parceled homogeneous adjuncts, homogeneous circumstances and parceled predicate, meaning, adjunct, circumstance and the main member of a one-syllable sentence are much less recorded. Most often, the writer used parcelat with a non-conjunctive connection, less often – with a conjunctive one, sporadically used parcelat, the formal marker of which is a dot pause between the components. We note the quantitative growth of cases of parcellation in the writer's artistic works belonging to the late period of creativity. In the research, for the first time, a comprehensive analysis of the parcelat within a simple sentence, used by Ivan Franko in the artistic works of different periods of creativity, was carried out, which made it possible to reveal dynamic processes in their functioning. We see the prospect of further exploration in the involvement of a larger number of Ivan Franko's artistic works in order to reveal their functional and pragmatic potential in the writer's idiostyle. Key words: simple sentence, segmentation, parcelat, expressive syntax, pragmatics of artistic text, Ivan Franko.
Otherization and Identity Distortion in Dangarembga’s Writing
Authors: Laheg Inas
Published: June 2024

In spite of the fact that most African novelists, penning stories in English language by the end of the 20th century and the beginning of the 21st century, were graduates of the British colonial missionaries and universities, they had yet been able to escape the suppressive ideology of colonization and become genuine mouthpieces for their native communities’ struggles and adversity. Amongst whom, the Zimbabwean Tsitsi Dangarembga rose to the fore as representative of her fellow countrywomen during the British colonization. Henceforth, concomitant with the rise of postcolonial criticism in the literary arena, this paper aims to address the European colonial mechanism of otherization and its impact on the identity construction of the otherized subject in Dangarembga’s novels, Nervous Conditions and The Book of Not. Dangarembga foreshadows the main thematic realm of her semi-autobiographical trilogy, through her first novel’s title which is reminiscent of Frantz Fanon’s preface in the book of The Wretched of the Earth. To unravel the intricate complexities of the colonizer/colonized contact, this study pinpoints the psychological confusion of the protagonist, Tambuzdai, as an exemplar of the colonized Black individual’s distress. To fathom the depth of Tambu’s psyche during those encounters, this paper relies on Elke Boehmer’s attribution of otherization as a Western self-projecting process that seeks to produce self-soothing and “dark mirror-images” of the other. In addition, Du Bois’s analysis of double consciousness seems to account for the protagonist’s identity crisis and self alienation. In conclusion, Dangarembga does not seem as an opponent of cultural exchanges in general or hybridity in particular, but she simply advocates cautious adaption that does not decentre and disregard one’s native-ness and cultural origins.

The objective of this study is to improve the filtration efficiency of commercially available polyethersulfone (PES) ultrafiltration (UF) membranes, with a specific focus on removing natural organic
matter (NOM) and preventing membrane fouling. The modification of UF membranes was accomplished by utilizing chitosan/multi-walled carbon nanotubes (CS/MWCNT-OH) and employing both dip and spin
coating techniques. The membrane surface morphologies were evaluated using the Attenuated Total
Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), Scanning Electron Microscopy (SEM),
Atomic Force Microscopy (AFM), and Energy-Dispersive X-ray Spectroscopy (EDX) techniques. Tests were
carried out to assess the effectiveness of the membranes in a laboratory-scale system using two primary water sources from Istanbul, specifically the Melen River and Terkos Lake. Total organic carbon (TOC), UV254 absorbance, turbidity, and trihalomethane formation potential (THMFP) were all measured as part of a thorough analysis. The surface morphology investigations verified the effective deposition of MWCNT-OH nanoparticles onto the membrane surface. This was corroborated by the reduction in the water contact angle, showing an improvement in the hydrophilicity of the membrane. The modified membranes demonstrated much higher TOC removal rates compared to the original membranes. Specifically, the removal efficiencies for Melen River and Terkos Lake were 37.14% and 56.86%, respectively. Nevertheless, the alteration of the surface led to a decline in membrane flux as a result of the concurrent drop in pore size. To summarize, the results of this work highlights the considerable capability of surface modification using CS/MWCNT-OH to improve the performance and antifouling characteristics of commercial PES UF membranes.

Метафоры старости в туристической и панорамной литературе в России (1880-1910)
Authors: Payoli Yana
Published: June 2024

Панорамная литература, представленная физиологическими очерками, описаниями нравов, бытовыми картинами, и практическая литература путешествий (путеводители, справочники, туристические указатели) в силу своих особенностей по-разному описывают пространство. Среди стилистических приемов, которыми пользуются авторы путеводителей и очерков нравов, немаловажное место занимает метафорическая персонификация. Наделение географических мест человеческими свойствами включает в себя и характеристики по возрасту. В путеводителях метафоры, связанные с возрастом, отличаются от подобных метафор в физиологических очерках. Сравнительный анализ образов старости в этих текстах представляет интерес для описания жанровых особенностей как утилитарного путеводителя, так и «социокультурных» физиологий.
