Integrated approach for groundwater potential exploration in Abbay River Basin, East Africa
Authors: Yoshe Agegnehu Kitanbo 
Published: March 2024

AbstractThis paper presents and examines groundwater potential zones with the help of remote sensing and GIS methods for controlling and investigating the geospatial data of each parameter. Groundwater is a very important source for water supply and others, considering its availability, quality, cost, and time-effectiveness to develop. It is virtually everywhere and yet variable in quantity. Because of several conditions, such as rapid population growth, urbanization, industrialization, and agricultural development, groundwater sources are under severe threat. Climate change plays an important role in the quality and quantity of groundwater potential. In addition, climate change severely affects parameters that influence groundwater recharge. Unreliable exploitation and poor quality of surface water resources tend to increase the decline in groundwater levels. Hence, it is necessary to identify groundwater potential zones that can be used to optimize and monitor groundwater resources. This study was conducted in the Abbay River Basin and identifies the location of groundwater potential for developing new supplies that could be used for a range of purposes in the study area, where groundwater serves as the main source for agricultural purposes rather than surface water. Seven selected parameters—lineament density, precipitation, geology, drainage density, land use, slope, and soil data—were collected, processed, resampled, projected, and reclassified for hydrological analysis. For the generation of groundwater zones, weightage was calculated using an analytical hierarchy method, reclassified, ranked, and overlaid with GIS. The obtained results of weightage were lineament density (37%), precipitation (30%), geology (14%), drainage density (7%), land use land cover (5%), slope (4%), and soil (3%). The consistency ratio estimated for this study was 0.089, which was acceptable for further analysis. Based on the integration of all thematic layers and the generated groundwater potential zones, the map was reclassified into five different classes, namely very good, good, moderate, poor, and very poor. The results of this study reveal that 1295.33 km2 of the study area can be considered very poor, 58,913.1 km2 is poor, 131,323 km2 is moderate, 18,557 km2 is good, and 311.5 km2 is very good. Any groundwater management project performed in the better regions would offer the greatest value. A similar study would be valuable before planning any water resource development activity, as this would save the expense of comprehensive field investigations. This study also demonstrates the importance of remote sensing and GIS techniques in mapping groundwater potential at the basin scale and suggests that similar methods could be applied across other river basins.
Road traffic flow and air pollution concentrations: evidence from Japan

Published: March 2024

AbstractVehicular emissions are a major global health concern. The aim of this study is to examine the short-term relationship between road traffic flows and air pollution concentrations in Japan. Our approach involves matching hourly data from the 2015 Road Traffic Census to data from nearby air pollution monitoring and meteorological stations and estimating a dynamic panel model. We focus on four pollutants designated under the vehicle emission standards of Japan: nitrogen oxides (NOx), carbon monoxide (CO), nonmethane hydrocarbons (NMHC), and fine particulate matter (PM2.5). The standard estimates indicate that short-run pollution concentration-road traffic flow elasticities are 0.04–0.05 for NOx, CO, and NMHC, and insignificant for PM2.5. Long-term effects are also estimated. We apply the estimates to a case study on the link between road traffic flows and meeting the new World Health Organization air quality guidelines.
Biochar-supported zero-valent iron enhanced arsenic immobilization in a paddy soil: the role of soil organic matter

Published: March 2024

AbstractArsenic (As) detoxification in polluted soils by iron-based materials can be mediated by the endogenous soil organic matter (SOM), nevertheless the mechanisms remain unclear. Herein, endogenous SOM in a paddy soil was substantially removed to understand its roles on As immobilization by biochar-supported zero-valent iron (ZVI/BC). The results demonstrated that ZVI/BC application significantly decreased As bioavailability by 64.2% compared with the control soil under the anaerobic condition. XPS and HR-TEM suggested As immobilization by ZVI/BC mainly invoked the formation of ternary complexes (i.e., As-Fe-SOM). However, SOM depletion compromised the efficacy of ZVI/BC for As immobilization by 289.8%. This is likely because SOM depletion increased the fulvic acid and OH− contents in soils. Besides, ZVI/BC increased the proportion of As(III) in available As fraction, but SOM depletion altered the mechanisms associated with As(V) reduction. That is, As(V) reduction resulted from the reductive capacity of ZVI in the pristine soil, but the As(V)-reducing bacteria contributed greater to As(V) reduction in the SOM-depleted soil. Additionally, SOM depletion boosted the abundances of Fe(III)- and As(V)-reducing bacteria such as Bacillus and Ammoniphilus in soils, which enhanced the dissimilatory arsenate reduction. Thus, this work highlighted the importance of SOM in the remediation of As-contaminated soils by ZVI/BC.

AbstractIn this paper, we study the superconvergence of the semi-discrete discontinuous Galerkin (DG) method for linear hyperbolic equations in one spatial dimension. The asymptotic errors in cell averages, downwind point values, and the postprocessed solution are derived for the initial discretization by Gaussian projection (for periodic boundary condition) or Cao projection Cao et al. (SIAM J. Numer. Anal. 5, 2555–2573 (2014)) (for Dirichlet boundary condition). We proved that the error constant in the superconvergence of order $$2k+1$$

Published: March 2024

Abstract
Introduction
Intimate partner violence (IPV) in pregnant women is considered one of the most important types of violence, which can include physical, psychological abuse and sexual violence. During the lockdown due to COVID-19, the home is at risk of becoming a very dangerous place for victims of domestic violence. We aimed to determine the prevalence of IPV and associated factors in pregnant women in Qazvin, Iran.

Methods
This cross-sectional study was conducted on 450 pregnant mothers who were referred to the Kowsar Hospital Prenatal Clinic in Qazvin in 2021. Participants were assessed using a questionnaire consisting of four parts (demographic data, Abuse Assessment Screen (AAS) for domestic violence, The Revised Conflict Tactics Scale (CTS2) for IPV. Data were collected and analysis was performed via SPSS software version 22 using a non-parametric test; Mann–Whitney and × 2 tests.

Results
The overall prevalence of IPV was higher in pregnant women than their husbands in Qazvin. The most common form of IPV was psychological aggression (24.8%), followed by scale of injury (8.2%), physical (3.3%) and sexual (4.2%) violence. In addition, analysis of the AAS questionnaire shows that psychological violence is the most common form of domestic violence among pregnant women.

Conclusion
In this study, IPV in pregnant women has increased slightly compared to studies conducted in the years leading up to the COVID-19. Risk of IPV was not related to previous COVID-19 infection. Collaborative efforts between various stakeholders and policy actions must be taken to ensure the safety and protection of pregnant women during this challenging time.

Abstract
Purpose
The aim of this study was to explore the relationships between single-nucleotide polymorphisms (SNPs) of crucial molecules in the cGAS-STING signalling pathway and the susceptibility to, induction chemotherapy response of, and prognosis of acute myeloid leukaemia (AML) in Chinese patients.

Methods
Thirteen SNPs of crucial molecules in the cGAS-STING signalling pathway were genotyped in 262 AML patients using the Sequenom MassARRAY system. The associations of SNPs with susceptibility, and induction chemotherapy response were analysed using the chi-square test or Fisher’s exact test and univariate binary logistic regression, the connection of SNPs with prognosis of AML was analysed using the log-rank test, and Kaplan–Meier curves were applied for survival estimation.

Results
In our study, gene polymorphisms of cGAS-STING signalling pathway molecules could be vitally associated with AML. In the recessive model, the cGAS rs311678 gene polymorphism could be closely related to AML susceptibility (CC vs. TT + TC, odds ratio (OR) = 0.480, 95% confidence interval (CI) = 0.260–0.889, p = 0.020). Moreover, IKKA rs3808917 might be associated with the WBC count, cGAS rs311678 could be associated with the bone marrow (BM) blast percentage, and NF-κB rs1056890 under codominant and recessive models could be connected with the HGB level. Patients who were STING rs7380272 TT/CT carriers was likely to have higher insensitivity to induction chemotherapy than CC carriers (TT + CT vs. CC, OR = 2.917, 95% CI = 1.073–7.929, p = 0.036). Survival analysis indicated that the IKKB rs3747811 TT genotype might be associated with decreased overall survival (OS) (p < 0.05).

Conclusions
SNPs of molecules in the cGAS-STING signalling pathway could be significantly associated with AML. The cGAS rs311678 gene polymorphism could be associated with AML susceptibility, the STING rs7380272 variant might be related to induction chemotherapy response, and IKKB rs3747811 tended to be associated with AML overall survival. Moreover, IKKA rs3808917 could be associated with the WBC count, cGAS rs311678 could be associated with the BM blast percentage, and NF-κB rs1056890 might be related to the HGB level.

Published: March 2024

AbstractThe performance of an ejector-assisted condenser outlet split dual-evaporator cycle is compared with a conventional dual-evaporator cycle albeit consisting a pressure reducing valve. The cycles do not employ any separator due to its inability to efficiently separate the liquid and the vapor phases. The comparison of both the cycles has been made for the same cooling capacity in low-temperature evaporator and unit flow rate of R134a and R1234yf as refrigerants. The impacts of changing the operating temperatures of evaporator and condenser have been examined in the current investigation. The study reveals that with the increase in temperature of the high-temperature evaporator, the cooling capacity of the high-temperature evaporator yields, while that of the low-temperature evaporator plummets in both the cycles. Further, the compressor work is allayed in the ejector-assisted cycle; thus, the COP is enhanced considerably. The percentage COP improvement over the basic cycle is obtained from 14.7 to 17.53% for the refrigerant R1234yf and from 14.45 to 17.32% for R134a; however, the COP of both the cycles with R12134yf is slightly lower than with R134a. The ejector has been modeled assuming a constant pressure theory. The observed trend indicates that the entrainment ratio is improved with the rise in the temperature of low-temperature evaporator, whereas it is decreased with the rise in the temperature of high-temperature evaporator.

Published: March 2024

AbstractThe Resilience Evaluation Scale (RES) is a newly developed measure of resilience written in both English and Dutch languages. To date, there have not been comprehensive psychometric evaluations of the RES’ performance, including validity for use in non-Western cultural populations and languages. In our attempt to address this void, we conducted a psychometric evaluation of the RES utilizing a Western, sample of U.S. college students and non-Western sample of Chinese college students. Our psychometric evaluation of the RES in a Western, English-speaking sample of U.S. college students indicated mixed results on the construct validity of the RES for measuring resilience. We also found that the factor structure of the RES lacked configural invariance across U.S. college student and Chinese college student samples. Results suggested that additional research is needed to assess whether the RES appropriately measures internal factors of resilience or requires modification. We also highlight the need for continued development of cross-culturally valid measures, and possibly different conceptualizations, of resilience across cultural and linguistic groups.

Published: March 2024

AbstractRaffinose Family Oligosaccharides (RFOs) are a kind of polysaccharide containing D-galactose, and they widely exist in higher plants. Synthesis of RFOs begins with galactinol synthase (GolS; EC 2.4.1.123) to convert myo-inositol into galactinol. The subsequent formation of raffinose and stachyose are catalyzed by raffinose synthase (RS; EC 2.4.1.82) and stachyose synthase (STS; EC 2.4.1.67) using sucrose and galactinol as substrate, respectively. The hydrolysis of RFOs is finished by α-galactosidase (α-Gal; EC 3.2.1.22) to produce sucrose and galactose. Importance of RFOs metabolism have been summarized, e.g. In RFOs translocating plants, the phloem loading and unloading of RFOs are widely reported in mediating the plant development process. Interference function of RFOs synthesis or hydrolysis enzymes caused growth defect. In addition, the metabolism of RFOs involved in the biotic or abiotic stresses was discussed in this review. Overall, this literature summarizes our current understanding of RFOs metabolism and points out knowledge gaps that need to be filled in future.
Why Didn’t Brazilian Democracy Die?
Authors: Melo Marcus André , Pereira Carlos 
Published: March 2024

ABSTRACTBrazil, for many scholars and pundits, showcased the risk of democratic breakdown with the election of a far-right populist like Jair Bolsonaro. Against pessimistic expectations, however, not only has Brazilian democracy survived but politics has returned to business as usual. What can explain this supposedly unanticipated outcome? This article provides an analytical assessment of this this puzzle and offers an alternative explanation. We argue that both the diagnoses of Brazilian institutions and the predictions made were misguided. We explore the role played by the Supreme Court, party system, media, and congressional politics in restricting Bolsonaro’s illiberal initiatives.
#Resistencia: Indigenous Movements, Social Media, and Mobilization in Latin America

Published: March 2024

AbstractIndigenous peoples in Latin America have produced some of the region’s strongest and most enduring social movements, drawing on a diverse repertoire of contention to pursue their goals. In the twenty-first century, social media have transformed the landscape of collective action, compelling Indigenous movements to navigate the evolving dynamics of digital platforms. There is an ongoing debate in the literature regarding the role of social media in mobilization. But we know relatively little about how social media fit into the tactical repertoires of Indigenous actors and what tasks these platforms are used for. This article addresses this gap through an examination of how Indigenous actors use social media during protest events. We conducted a comparative analysis of social media content produced by Indigenous social movement organizations during major protest events in three countries from 2018 to 2019. We find that the most common functions include activating supporters and exposing state violence. These functions support several of the organizations’ core mobilization tasks by providing actors with tools to complement collection action.

Published: March 2024

AbstractNon-alcoholic fatty liver disease (NAFLD), which is a prevalent hepatic condition worldwide, is expected to develop into the leading reason for end-stage fatty liver in the forthcoming decades. Incorporating rapeseed oil into a balanced diet may be beneficial in improving NAFLD. The goal of this trial was to evaluate the impact of substituting ghee with rapeseed oil on primary outcomes such as fatty liver and liver enzymes, as well as on secondary outcomes including glycaemic variables, lipid profile and anthropometric measurements in individuals with NAFLD. Over 12 weeks, 110 patients (seventy men and forty women; BMI (mean) 28·2 (sd 1·6 kg/m2); mean age 42 (sd 9·6) years), who daily consumed ghee, were assigned to the intervention or control group through random allocation. The intervention group was advised to substitute ghee with rapeseed oil in the same amount. The control group continued the consumption of ghee and was instructed to adhere to a healthy diet. Results showed a significant reduction in the steatosis in the intervention group in comparison with the control group (P < 0·001). However, a significant change in the levels of alanine aminotransferase (–14·4 μg/l), γ-glutamyl transferase (–1·8 μg/l), TAG (–39·7 mg/dl), total cholesterol (–17·2 mg/dl), LDL (–7·5 mg/dl), fasting blood glucose (–7·5 mg/dl), insulin (–3·05 mU/l), Homeostatic Model Assessment for Insulin Resistance (–0·9), Quantitative Insulin-Sensitivity Check Index (+0·01), weight (–4·3 kg), BMI (–0·04 kg/m2), waist (–5·6 cm) and waist:height ratio (–0·04) was seen in the intervention group. The consumption of rapeseed oil instead of ghee caused improvements in liver steatosis and enzymes, glycaemic variables and anthropometric measurements among individuals with NAFLD.
Discounted densities of overshoot and undershoot for Lévy processes with applications in finance
Authors: Gao Hui , Yin Chuancun 
Published: March 2024

AbstractThis paper considers the first passage times to constant boundaries and the two-sided exit problem for Lévy process with a characteristic exponent in which at least one of the two jumps having rational Laplace transforms. The joint distribution of the first passage times and undershoot/overshoot are obtained. The processes recover many models that have appeared in the literature such as the compound Poisson risk models, the perturbed compound Poisson risk models, and their dual ones. As applications, we obtain the solutions for popular path-dependent options such as lookback and barrier options in terms of Laplace transforms.

Published: March 2024

AbstractUsing the SDSS spectroscopy, we have carried out fine optical spectral classification for activity types for 710 AGN candidates. These objects come from a larger sample of some 2,500 candidate AGN using pre-selection by various samples; bright objects of the Catalog of Quasars and Active Galactic Nuclei, AGN candidates among X-ray sources, optically variable radio sources, IRAS extragalactic objects, etc. A number of papers have been published with the results of this spectral classification. More than 800 QSOs have been identified and classified, including 710 QSOs, Seyferts and Composites. The fine classification shows that many QSOs show the same features as Seyferts, i.e., subtypes between S1 and S2 (S1.2, S1.5, S1.8 and S1.9). We have introduced subtypes for the QSOs: QSO1.2, QSO1.5, QSO1.8, QSO1.9, though the last subtype does not appear in SDSS wavelength range due to mostly highly redshifted Hα (the main line for identification of the 1.9 subtype). Thus, independent of the luminosity (which serves as a separator between QSOs and Seyferts), AGN show the same features. We also have classified many objects as Composites, spectra having composite characteristics between Sy and LINERs, Sy and HII or LINERs and HII; in some cases all three characteristics appear together resulting as Sy/LINER/HII subtype. The QSOs subtypes together with Seyfert ones allow to follow AGN properties along larger redshift range expanding our knowledge on the evolution of AGN to more distant Universe represented by QSOs.

Published: March 2024

AbstractMost (yet not all) results of atomic physics research of Charlotte Moore Sitterly (CMS), which was closely connected to astrophysics, are now incorporated in online databases, one of which is the Atomic Spectra Database of the National Institute of Standards and Technology. The use of this database extends far beyond astrophysics, but this review focuses on astrophysical applications. The impact of CMS’s work on modern atomic physics and other sciences is discussed, and problems that urgently need solutions are outlined.
