Source Characteristics of Tectonic and Induced Events near St. Gallen, Switzerland: Utilizing the Empirical Green’s Function Method and Generalized Inversion Technique
Authors: Jeong SeongJu , Lui Semechah K. Y. 
Published: December 2024

ABSTRACT
Stress drop is a kinematic source parameter essential for understanding the physical mechanisms behind natural or human-induced seismic events, contributing to ground shaking and seismic hazards. This study aims to estimate the Brune stress drop of earthquakes across Switzerland for the years 2013–2014. The geothermal energy project in St. Gallen induced 347 events with a maximum magnitude of ML 3.5, providing an opportunity to quantitatively compare the physical differences between induced and tectonic earthquakes in the surrounding region. Using the S-wave Fourier amplitude spectra of 82 induced events and 83 tectonic earthquakes, we apply two spectral methods to isolate the source terms of the earthquakes: (1) empirical Green’s functions (EGFs) and (2) the nonparametric generalized inversion technique (GIT). GIT is applied to all the induced and tectonic earthquakes, whereas six of the induced events (ML&gt;1.4) with appropriate EGF events are also analyzed using the EGF method. For these six events, both methods yield consistent average and median stress-drop values: 16.4 and 18.1 MPa for EGF, and 14.4 and 14.3 MPa for GIT, respectively, which are a factor of 10 larger than those of induced earthquakes. This discrepancy is possibly due to the alteration of the stress state under the influence of pore fluid in the geothermal setting. Interestingly, we observe that the stress drop increases with seismic moment for both induced and tectonic events, which is consistent with previous findings, though we note the narrow magnitude range in this study. Such nonself-similar scaling, if true, may be related to the depth dependence of the stress drops for tectonic events and the perturbation of pore pressure for induced events.

ABSTRACT
Earthquake early warning (EEW) systems in Japan use data from as little as a single observation point, even at the stage in which only the P wave is detected at one point, to estimate the epicentral distance and magnitude to rapidly issue a warning. This approach aims to maximize lead time but has the drawback of significant estimation errors (epicentral distance: half to double, back azimuth: ±30°). Using distributed acoustic sensing (DAS) with a dense network of observation points allows for rapid and precise earthquake hypocenter determination, significantly reducing estimation errors compared to single-station methods in EEW system. However, no prior studies have investigated the immediacy of using DAS data—which is indispensable for early earthquake warnings. Therefore, we examined the use of DAS for rapid and precise hypocenter determination with the goal of integrating it into the EEW system. We used fiber-optic cables along the Kyushu Shinkansen to analyze strain-rate waveforms, detect P waves, and determine earthquake hypocenter locations. We detected P waves using short-term average /long-term average simultaneously across multiple channels. We then determined the epicenter using Hypomh. For rapid determination of the hypocenter location after P-wave detection, we assessed the hypocenter location each time the number of P-wave detection points increased by 20. For earthquakes with an epicentral distance of less than 50 km, we successfully determined the hypocenter within 12 km of the Japan Meteorological Agency-reported location. This was achieved by identifying the point where the sum of the maximum-likelihood estimation errors was minimized within 2 s of the initial P-wave detection in any channel. The findings suggest that an EEW system using DAS holds potential as a powerful tool to provide rapid and accurate hypocenter information, especially for near-field earthquakes that occur directly beneath populated areas, where lead times are short, and the potential damage is substantial.

Published: December 2024

Background: India has the largest adolescents population in the world, 253 million, nearly 23 percent of India’s population. Adolescents anemia is severe public health problem in India, 59.1% by NFHS. As adolescent age is formative years for development, anemia at this stage of life has some long-term consequences, as maternal and foetal deaths.
Methods: It was observational cross sectional study under field practice area of Rural Health Training Centre of Western Maharashtra. 350 adolescent girls were interviewed using predesigned, pretested questionnaire and their anemic status was assessed by hemoglobin estimation. Results were analyzed with the help of Microsoft Excel.
Results: The prevalence of anemia in this study was found to be 64.8%. The prevalence of mild and moderate anemia among study participants was 29.4 and 35.4%, respectively. Mean age of study participants was 14.8±2.36 years. The majority 68.57% of girls were Hindu by religion and nuclear family (43.42%). Most of the girls belonged to socioeconomic class III (30%) followed by class IV (21%). A significant association was found between the prevalence of anemia with, educational status of mother, and status of attainment of menarche with excessive bleeding and not receiving iron folic acid tablets and girls had history of worm infestation (p<0.05).
Conclusions: The prevalence of anemia among adolescent girls was very high, as compared to 59.1% by NFHS-5, which was higher in lower socio-economic strata and among those whose mothers were less educated and who attained menarche with excessive bleeding and not receiving iron folic acid tablets with history of worm infestation.

Authors: Das Dipak Kumar , Ladku Jadav Vishal 
Published: December 2024

Background: Early childhood care and development (ECCD) was a critical foundation for overall growth and development, not only of children but society on the whole which has severely neglected in India. According to NFHS almost half of all children under three were underweight. Prevalence of acute illness at the household level in Tripura was 12%. It is needed to draw the attention of people towards the person possessing nutrition and morbidity. The objectives of this study is to assess the nutritional status, prevalence of major morbidities and examine the impact of socio-demographic factors on nutritional status and morbidities in a block under study in Tripura.
Methods: In 2023 after receiving approval from KJSCE, IGNOU study centre, Mumbai, selected anganwadi students of Mechuria gram-panchayat of Tripura state were surveyed. We utilised Univariate, Bivariate and chi-square methods for this study.
Results: In Mechuria gram-panchayat 21% anganwadi students were underweight, 10% were obese and 57% Anganwadi students were suffered from acute illness. Common cold was 70% which was the highest prevalence. Major health problems were decreased with increasing parent’s age and their education and also raise this health problem with increasing age of Anganwadi teachers and helpers. It may be due to overburden of their other responsibilities.
Conclusions: Common cold, underweight and obese were the major health problem and government hospital played the main role in providing treatment facility in this village. Limitation of this study included that this study based on self-reporting.

Acute kidney injury (AKI), which is commonly caused by sepsis and contributes significantly to worldwide mortality, may affect patient outcomes and increase the risk of chronic disease. This review examines how urinary biomarkers can forecast renal recovery following sepsis. Conventional AKI diagnostics, like serum creatinine, suffer from delayed detection and poor specificity. Newer urinary biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL) and cell-free DNA (cfDNA), show potential for earlier detection and improved prognosis. NGAL, noted for its sensitivity to nephrotoxic and ischemic insults, shows potential in predicting AKI onset and recovery. Similarly, cfDNA levels, reflecting systemic cell death, correlate with sepsis severity and renal outcomes. Despite their promise, variability in biomarker levels due to comorbidities and the need for standardized diagnostic thresholds remain challenges. Combining multiple biomarkers may enhance diagnostic accuracy, offering a more comprehensive assessment of kidney function and sepsis-induced AKI (S-AKI). Further research is needed to validate these biomarkers and integrate them into clinical practice for improving patient outcomes post-sepsis.

Published: December 2024

Under Bologna processes, it is important that educators understand and use assessment for formative purposes as well as traditional summative evaluation purposes. This small-scale exploratory study tested the Teachers Conceptions of Assessment (TCoA) inventory in the Portuguese higher education context. A convenience sample of Portuguese academic faculty (n=185) from five public universities and across multiple scientific areas were surveyed. Confirmatory factor analysis rejected the original model and preferred a four-factor model (i.e., improvement, assessment quality, institutional quality, and, reject assessment use) using just 15 of 27 items. Findings from this study indicate that, in line with Bologna intentions, Portuguese faculty seem to be taking a positive and constructive view of assessment as a tool for improved outcomes and have confidence in their evaluative practices. Faculty agreed that assessment was a high-quality process for improved outcomes and rejected its irrelevance. At the same time, they had a much weaker but positive view that assessment evaluated institutional quality. The study indicates that the TCoA inventory needs to be supplemented with different items and factors to capture the quality of Portuguese faculty conceptions of assessment.

Pondok Pesantren Darul Muttaqin, located in Batu City, East Java, is an Islamic boarding school with a mission to provide non-profit education services. The current number of students is 63, with predictions for an increase in the coming years. This growth in student numbers will impact the increasing demand for drinking water that the boarding school must supply. The current situation shows that the drinking water supply capacity is insufficient for the number of students and staff. Additionally, relying on gallon water providers incurs high costs, traditional methods require significant energy and time, and the quality of the water produced is still inadequate, posing a health risk. Based on an analysis of the partner’s situation and conditions, this community service initiative aims to provide training through technology transfer on drinking water treatment to the students and staff of Pondok Pesantren Darul Muttaqin. The community service activities include delivering materials on drinking water quality, introducing the reverse osmosis system for water treatment, practical sessions on using reverse osmosis equipment, and monitoring. The success of this initiative is measured through partner satisfaction surveys, where 43% of respondents agreed, and 15% strongly agreed with the benefits of the activity.

Abstract

Background and Aims: Between 200,000 and 300,000 children with sickle cell disease are born in Africa every year, with 75–80% of these children living in sub-Saharan Africa. In newborns with sickle cell disease (SCD), significant iron accumulations may develop because of their increased risk of requiring multiple blood transfusions. Limited information is available regarding liver enzyme levels in Ghanaian children with sickle cell disease. This study aimed to assess the hepatic effects of haemotransfusion in paediatric sickle cell disease patients in steady state by measuring liver and iron markers.
Methods: This case-control research enrolled 129 children with SCD and 60 children without SCD from the Asokwa children hospital sickle cell clinic and child welfare clinic. Participants' information sociodemographic information, history of blood transfusion and Sickle cell genotype were thoroughly documented using a structured questionnaire and patient case records. Venous blood was drawn from each participant to evaluate serum ferritin, serum iron, total iron binding capacity (TIBC), alanine transaminase (ALT), aspartate aminotransaminase (AST) and gamma-glutamyl transferase (GGT) levels. Statistical significance was considered at p<0.05.
Result: Significant elevated serum iron, total iron binding capacity, ALT and GGT levels were observed in children with SCD than children without SCD. Children with “SS” genotype recorded the highest transfusion history, and had significantly elevated levels of serum iron and transferrin saturation than those with genotype “SC” (p < 0.05). Elevated concentration of serum iron and transferrin saturation were also observed in children with SCD who last received haemotransfusion between 0-6 months ago than children who received transfusion between 7-12 months ago (p < 0.01), and more than or equal to 13 months ago (p < 0.05). Similarly, children with SCD who had haemotransfusion history of 0-6 months ago had significantly increased levels of ferritin concentration and ALT concentration than more than or equal to 13 months ago. In a linear regression prediction model, an increase in the number of frequency of haemotransfusion among children with SCD resulted in 2.6 umol/L increase in serum iron levels (β = 2.6, p < 0.05), 40 ng/mL increase in ferritin levels (β = 40, p < 0.05) and 8% increase in transferrin saturation (β= 8, p < 0.05) among children with SCD.
Conclusion: Elevated iron stores and liver enzymes are associated with sickle cell disease in children, especially those with history of transfusion should be routinely monitored for elevated iron stores and liver enzymes for early interventions and managements.
