Diagnostics of permanent magnet synchronous motors (PMSM) is one of the key factors in ensuring the smooth operation of electric drives for various purposes. Various malfunctions of synchronous drives, such as a violation of the original geometric shape, a decrease in the coercive force of the magnets, various destruction of the magnets, such as cracks and chips, can be detected by analyzing the linear current, namely the spectral characteristic. Methods for identifying «mark» on the spectral characteristics and their comparison are referred to as signature analysis. Due to the need to detect the slightest deviations from the original signature, an accurate comparison of the original signal with its standard is necessary. This approach is implemented only under the condition of unambiguous coincidence of the studied signals in terms of their periods and groups of magnets as signal sources. Wavelet transform can be applied as a method of synchronization of two signals. Aim of research The article is devoted to the issues of application of wavelet theory for synchronization of the studied current signal containing diagnostic information with the reference signal of a serviceable PMSM, which will allow performing a direct comparison of current envelopes and identifying linear current signatures of faults in the structure of the magnetoelectric system of the PMSM. Research methods The work uses methods of theoretical and experimental research. To conduct theoretical research, the following software packages were used: Excel and MathCad; MatLab software package for wavelet analysis and Fourier analysis; Elcut software package for developing a computer model and conducting simulation modeling; fundamentals of wavelet theory. Results A synchronization method for obtaining data from the PMSM has been developed, which allows one to identify linear current signatures and uniquely identify signal periods responsible for a certain group of magnets. It has been shown that the use of wavelet transform for synchronization of the studied signal significantly expands the capabilities of signature analysis of linear current.

Unintended Consequences

Published: November 2024

This dissertation seeks to expand our understanding of the use of financial statement assurance (FSA) when raising capital by focusing on the influence of competition among capital seekers. The first essay provides an overview of markets for early-stage capital to highlight how they compare and contrast in terms of key market participants, disclosure requirements, and recent performance. The setting for this dissertation and the empirical work discussed in the second and third essay is the United States Regulation Crowdfunding (RegCF) market where a recent amendment allows startups to purse a higher overall maximum campaign target beginning on March 15, 2021 ($5,000,000, versus $1,070,000 prior to this date). The amendment is employed as a shock to competition among capital seekers and used to examine whether such competition impacts the demand for FSA (an internal signal of offering quality) in the second essay. The third essay examines whether such competition impacts the supply for FSA (an external signal of offering quality). The second essay documents evidence suggesting that this amendment discourages incremental investment in FSA among smaller RegCF campaigns, which also adversely impacts campaign outcomes as campaigns attract less investors to fund their campaign. These results suggest that there are unintended consequences to this amendment and, as a result, the amendment needs to be re-examined by regulators. The third essay documents evidence that high-quality auditors are less likely to provide FSA services to smaller campaigns following the amendment. Univariate results suggest that the amendment leads to a deterioration in the quality of RegCF campaigns. Collectively, these results suggest that as increasing competition reduces quality among campaigns competing for capital post-amendment, campaigns' decreased quality leads to decreased FSA services being provided by high-quality auditors. This study contributes to the accounting literature by providing evidence suggesting that high-quality auditors prefer less risky clients.

This research aims to determine the neutrality regulations of civil servants in general elections. To achieve this goal, analysis was carried out on secondary data or library materials consisting of primary legal materials, secondary legal materials, and tertiary legal materials. To complete secondary data, interviews were conducted with sources consisting of experts in the field of civil service law and general elections, as well as practitioners such as the State Civil Service Agency, the State Civil Service Commission, and the General Election Supervisory Agency of the Republic of Indonesia. This research applied a statute approach and combined it with a historical approach and a conceptual approach. The results of the research showed that from 1966 until now, the regulation of the neutrality of the State Civil Service in general elections has undergone changes in the subject and object of its regulation. However, this arrangement has not been able to guarantee the neutrality of the State Civil Service in general elections. This is inseparable from the political system, which does not yet support the realization of neutrality of the State Civil Service in General Elections.

Authors: Ajitha Kolakotla , R. Sheela S. , S. Nandini
Published: November 2024

Background: Epilepsy is the second common chronic neurological disorder complicating pregnancy after migraine. Incidence of seizure disorder in women attending antenatal clinics is estimated to be 0.3-0.5% of all births. These pregnancies are a challenge to patient and clinician, the double burden of seizures and the antiepileptic drugs (AED) exposure are responsible for the poorer outcome of infants. The aim of the study is to analyse the fetal and maternal outcome in pregnancies that are complicated by epilepsy.
Methods: This was a single centre retrospective study on pregnant women with epilepsy at a tertiary care centre from the period of 01st August 2021 to 1st August 2024. The data of all booked antenatal patients diagnosed with epilepsy was collected from the labour records and electronic medical records. Details included in the study were preconceptionally counselling, age, parity, gestational age at the time of delivery, age of onset of epilepsy, duration of epilepsy, seizure during pregnancy, antiepileptic drug usage in pregnancy, maternal complications and fetal outcomes.
Results: Out of the total 6400 deliveries over in our institution I identified 54 patients with epilepsy complicating pregnancy thus giving a incidence of 0.84 %. Majority of patients were in the age group of 20-30 years . Having a duration of seizures more than 10 years. 87.03 % of patient had GTCS type of seizure and 68.51% of patient gave a history of seizure free period prior to pregnancy. 24.07 % of patients had incidence of antepartum seizures, though most of the patients didn’t need any change in dose or medication. Even with the episodes of antepartum seizures 83.34% of females had a term delivery, 59.25 % patients had a normal delivery and 59.25 % of babies were >2.5 kg at the time of birth. Only 1 child was born with congenital anomalies and 25.92% children required NICU admission.
Conclusions: In this study we observed that though pregnancy with epilepsy needs comprehensive antenatal care and this results in uneventful pregnancies with good feto-maternal outcome.

Published: November 2024

Background: Alzheimer’s disease depicts the characteristic features of intracellular neurofibrillary tangles and extracellular amyloid plaques. Kalyanaka ghrita (KG) is an Ayurvedic formulation used to treat impaired learning and memory such as Manasmandata or Buddhimandyata. KG is traditionally used to enhance memory. The constituents present in KG are also reported to be memory-enhancing, anti-inflammatory, and antioxidant and KG is reported to be effective in neurodegeneration in rats induced by β-amyloid. Aim: This study is aimed to validate the effect of KG on memory deficit, tauopathy and neurodegeneration induced by intracerebroventricular administration of okadaic acid. Methods: Okadaic acid was administered intracerebroventricularly on day 7 to the Wistar rats. KG was administered orally or intranasal from day 14 to 35 to the respective groups. The behavioural parameters on spatial memory, social recognition, and novel object recognition tests were determined. The molecular parameters such as brain acetylcholinesterase activity, protein phosphatase 2A, antioxidant parameters, monoamine levels and the brain histopathology were studied. Results: KG treatment significantly improved cognition, as evidenced by a decrease in escape latency, path length, and social and novel object recognition tests. KG treatment also increased the brain Protein phosphatase 2A, reversed the oxidative stress, and decreased brain acetylcholinesterase. The brain monoamines were reversed upon treatment with KG. Further, the molecular and histological studies confirmed the prevention of neuronal damage. Conclusion: These findings imply the traditional nootropic property of KG. The neuroprotective properties and decreased neurofibrillary tangles upon treatment with KG suggest KG to be a potential therapy for AD-like neurodegeneration.

Coronaviruses cause diseases of the respiratory tract, gastrointestinal tract and central nervous system, which threaten human health and contribute to economic losses. Innovative production technologies make it possible to use bioactive compounds as antiviral agents. Most fruits, vegetables and plant products contain flavonoids. Numerous studies have demonstrated the health-promoting effect of this group of compounds resulting from their antioxidant potential. The activity of an antioxidant in the body is the result of many factors that modulate the reactivity and physicochemical properties, among which the chemical structure is the most important. Bioinformatics tools using molecular modeling often precede research using in vitro and in vivo methods. The aim of this review is to present the mechanism of antiviral action of flavonoids against SARS-CoV-2, responsible for COVID-19. Studies using virtual molecular docking models were collected to test the affinity of flavonoids for key proteins of the SARS-CoV-2 virus replication cycle. Among the flavonoids with antiviral activity, the most active were apigenin, luteolin, isorhamnetin, kaempferol, myricetin, quercetin, hesperetin, naringenin and genistein. Food products with a high content of these compounds are indicated.

Published: November 2024

Pharmacogenomics lies at the intersection of pharmacology and genomics. It analyzes the impact of genetic variants on patient’s response to a specific drug. Pharmacogenomic tests involve the analysis of variants of genes responsible for drug metabolism, to determine the rate of drug metabolism and apply this information to clinical practice. Pharmacogenomics assists in selecting the appropriate drug and adjusting its dose to minimize side effects while maximizing the effectiveness of a drug, which accelerates the introduction of effective therapy. The prospects for its application in psychiatry are promising, although the creation of uniform recommendations is difficult due to the complexity of mental disorders and the influence of other factors, such as interactions between medications. Therefore, recommendations created by different institutions differ significantly. The aim of this article is to discuss the current possibilities of using pharmacogenomics in psychiatry and the difficulties of introducing it as a standard of psychiatric treatment.

Objective. The complex assessment of clinical, functional and hemodynamic status change according to echocardiography and right heart catheterization (RHC) within 12 months after pulmonary arterial hypertension (PAH) verification in real clinical practice. Design and methods. Incident adult patients with PAH were included in a longitudinal prospective observational study with a retrospective component after PAH verification based on RHC. The data were received by patients interviewing and medical documentation analysis at enrollment and every 3 months during one-year observational period. The retrospective design was used to collect information before enrollment. Results. Thirty three patients were enrolled. 64 % of patients received monotherapy as initial PAH-specific therapy, 24 % — a double combination, while the rest received calcium channel blockers. Follow-up echocardiography was performed in 75,8 % patients. There was a significant increase in median tricuspid annular plane systolic excursion (TAPSE, p = 0,001), median left ventricular end-diastolic diameter (p = 0,004) and a decrease in the anteroposterior diameter of the left atrium (p = 0,016) during the follow-up period. There were no significant changes in the size of the right heart chambers, pulmonary artery systolic pressure, or pulmonary artery size. Follow-up RHC was performed in 16 (48,5 %) patients. There was a significant improvement in cardiac output (p = 0,006) and cardiac index (p = 0,012), venous blood oxygen saturation (p = 0,045) and significant decrease of stroke volume (p = 0,021) during the follow-up period. The initial 6-minute walk test was performed in 75,8 % patients, the median distance was 340 m. During follow-up data were available in 14 patients, the median distance was 398 m. Median time from PAH onset to PAH verification was 13,5 months with a direct correlation between the time from the PAH onset to PAH verification and WHO functional class at the time of diagnosis (ρ = 0,394, p < 0,05). Within 12 months after PAH verification most patients subjectively noted the absence of positive dynamics in symptoms (88 %). Conclusions. We suppose that optimizing the treatment regimen for patients with PAH, improving access to PAH-specific therapy can improve the clinical and hemodynamics status and prognosis of patients with PAH.

Lastly, we have shown that both the image and inverse image of \(\mathcal{L}\)-weakly 1-absorbing prime ideals (filters) result in \(\mathcal{L}\)-weakly 1-absorbing prime ideals (filters).
Kreacja prawa. Prawodawstwo między społeczną użytecznością a rozumną zgodą
Authors: Chmieliński Maciej
Published: November 2024

Autor wychodzi od stosunkowo dobrze rozpoznanego w literaturze zjawiska (m.in. F.A. von Hayek, H. Berman, J. Wróblewski, B. Tamanaha, J. Habermas, L. Wintgens) stopniowego utożsamiania prawodawstwa z legislacyjną kreacją. Ten dominujący sposób myślenia, określany przez Autora mianem „prawnego kreacjonizmu” powoduje zwiększanie się zakresu i ilości prawnej regulacji. Regulacja zaczyna w coraz większym stopniu dotykać różne sfery życia społecznego. Konsekwencją jest inflacja przepisów oraz fragmentaryzacja i niepewność prawa. Autor stawia tezę, że zjawisko to wiąże się z historyczną dominacją konstruktywizmu i utylitaryzmu, dwóch sposobów myślenia o stanowieniu prawa operujących na silnie antydogmatycznym fundamencie modernizacji. Tezy tej dowodzi odwołując się do koncepcji odzwierciedlających jego zdaniem historyczną ewolucję myślenia o prawodawstwie. Ewolucja ta zainicjowana została przez późnośredniowieczny nominalistyczny zwrot w epistemologii. Jej kolejne etapy obejmowały: wczesno-nowożytne oddzielenie polityki od moralności, etatyzację prawa, oświeceniowe i pozytywistyczne oddzielenie prawa od moralności, indywidualistyczną koncepcję naturalnych uprawnień, wyodrębnienie się władzy prawodawczej (podziały władzy), demokrację, zjawisko państwa narodowego i związanego z nim narodowego prawa oraz subiektywistyczny indywidualizm i nihilizm końca XIX wieku. Autor postuluje, by kreacjonizm współczesnego ustawodawcy – pokłosie głównie oświeceniowego projektu i jego romantycznej korekty – był limitowany. Źródłem tego ograniczenia powinno być jego zdaniem wzmocnienie w myśleniu o stanowieniu prawa, obecnych w nim już dyrektyw zachowawczej i tożsamościowej, opartych odpowiednio na założeniach epistemicznej niedoskonałości oraz kontynuacji i wspólnotowego zakorzenienia prawa.

Iako je već više od dvije decenije djelo Albe de Sespedes (1911–1997), italijansko-kubanske književnice, novinarke i angažovane intelektualke, konačno postalo predmet istraživanja, o čemu svjedoče brojne monografije, zbornici i naučni radovi, uprkos tome, neki od aspekata njenog raznorodonog stvaralaštva i dalje su ostali skrajnuti od strane kritike i čitalaca. Takva sudbina zadesila je treću zbirku pripovijedaka Fuga (1940), objavljenu dvije godine nakon mladalačkog romana Nessuno torna indietro, koji je doživio slavu svjetskih razmjera. Nakon kratkog osvrta na okolnosti u kojima su nastale pripovijetke, u radu se skreće pažnja na njihove najvažnije teme: pisanje i položaj i uloga žene u društvu. Takođe, analitički pristup imaće za cilj da osvijetli dodirne tačke ovog djela sa nekim od romanesknih ostvarenja Albe de Sespedes.
Um código baseado em evidências?
Authors: Gawski Mártin , Konzen Lucas
Published: November 2024

Um cenário favorável ao uso de pesquisas sociojurídicas empíricas na argumentação legislativa se desenhava quando se iniciaram no Congresso Nacional as discussões que culminaram na aprovação da Lei nº 13.105/2015, o Código de Processo Civil (CPC/2015). Afinal, estava difundida na comunidade jurídica brasileira a percepção de que reformas na legislação de Direito Processual Civil vinham sendo conduzidas sem base em evidências científicas. Além disso, uma agenda de pesquisa empírica sobre a Justiça Civil já estava em desenvolvimento no país. Nesse contexto, como os atores sociais que protagonizaram os debates legislativos sobre o CPC/2015 fizeram uso de pesquisas sociojurídicas empíricas? Para responder a essa pergunta, realizou-se uma análise detalhada da documentação produzida ao longo do processo legislativo, em busca de discursos com fundamento em estudos empíricos. A documentação analisada abrange a exposição de motivos do anteprojeto da Comissão de Juristas e os pareceres finais das comissões especiais do Senado Federal e da Câmara dos Deputados, bem como os registros das reuniões e audiências públicas que os antecederam. Ao contrário do que se imaginava, as perspectivas de elaboração de um código baseado em evidências não se confirmaram. A utilização de pesquisas sociojurídicas empíricas nos debates legislativos sobre o CPC/2015 foi escassa, com recorrentes referências a estudo sobre acesso à justiça da década de 1970 que não incluíra dados sobre a realidade brasileira. Ocasionalmente, dados empíricos foram apresentados para fundamentar argumentos, mas de modo pouco rigoroso, com imprecisão na identificação das fontes das informações e uso descontextualizado de levantamentos estatísticos. As percepções sobre o funcionamento do direito na realidade baseadas em experiências pessoais dos atores sociais prevaleceram nos debates legislativos.

The paper presents data on geochemical features of the water-rock system of the Skalinskoye radon water manifestation. The waters of the Skalinskoye manifestation by chemical composition belong to the SO4-HCO3 Na-Mg-Ca type with a total mineralization value of 279–787 mg/dm3. The geochemical parameters of the medium correspond to the oxidizing environment with Eh +84,6…+187,0 mV, pH 6.9–8.8 and O2dissolved concentrations of 3.75–9.93 mg/dm3. Radon activity is up to 572 Bq/dm3. The water-bearing rocks are represented by biotite granites of normal and moderately alkaline series, which are permeated by quartz and sericite-quartz veins. With an increase in the total mineralization of radon waters, the prevailing forms of migration are calcium, magnesium, nickel and strontium bicarbonates, nickel carbonate and magnesium sulfate. Uranium migrates mainly in the form of dissolved hydroxide U(OH)4(aq). According to saturation indices, all waters are saturated in relation to calcite, uraninite and amorphous uranium oxide.
Drivers of grape berry sugar accumulation in field conditions at local scale

Published: November 2024

The final sugar concentration in grapes is an important parameter for winegrowers as it determines the alcohol content by volume of the final wine, allowing the timing of harvest to be optimised. In this research, a comprehensive dataset spanning seven years and 18 sites located in Saint-Émilion, Pomerol and satellite appellations (Bordeaux, France) was used to assess how growth and developmental factors (berry weight and mid-veraison date, respectively) and environmental factors (vine water status, nitrogen status, and mean air temperature) influence the dynamics of sugar accumulation.
The results of this study highlight the strong influence of mean temperature on the timing of maximum sugar accumulation, the duration of sugar accumulation and maximum sugar concentration in grape berries. Berry weight and the rate of sugar accumulation also appeared to be significant drivers of final sugar concentration. Fast ripening and increased berry weight were associated with lower sugar concentrations. Sites were clustered according to parameters driving sugar accumulation dynamics and mapped at the scale of the study area, in order to link these findings to terroir expression. In this study, vine nitrogen status did not emerge as a significant explanatory variable in any of the models developed to analyse sugar accumulation dynamics and berry weight. A small but significant effect of vine water status on the precocity of the plateau and on berry weight was found.
These results provide a better understanding of the factors that affect the dynamics of sugar accumulation in grape berries, which can help vine growers adapt to climate change. For example, by promoting practices that delay the onset of ripening to shift to a cooler period of ripening through choice of plant material and management practices. Alternatively, this can be done through an increase in berry weight, which lowers grape sugar and therefore wine alcohol concentration, taking care not to excessively alter the skin-pulp ratio to avoid reducing secondary metabolites.

Published: November 2024

Teachers in elementary schools have not developed many science literacy problems so the science literacy competence of students has not been evaluated clearly and accurately. The purpose of this study is to develop a science literacy evaluation instrument and find out the feasibility of the developed instrument. The development of instruments in this study used a combination of Wilson and Oriondo and Antonio models. The instrument development steps include (1) test design, (2) test trials, and (3) test assembly. The sample number is 31 students. The sampling technique used is random sampling. The content validation test by four experts based on the Aiken assessment formula obtained a validity value of 0.9813 which means it is declared "valid" or worthy of use. Instrument validation is empirically declared "valid" and has an r value above 0.355.

Objectives. To estimate the effect of influenza vaccination disparities.

Methods. We compared symptomatic influenza cases between Black and White races in 2 scenarios: (1) race- and age-specific vaccination coverage and (2) equal vaccination coverage. We also compared differences in household composition between races. We used the Framework for Reconstructing Epidemiological Dynamics, an agent-based model that assigns US Census‒based age, race, households, and geographic location to agents (individual people), in US counties of varying racial and age composition.

Results. Influenza cases were highest in counties with higher proportions of children. Cases were up to 30% higher in Black agents with both race-based and race-equal vaccination coverage. Compared with corresponding categories of White households, cases in Black households without children were lower and with children were higher.

Conclusions. Racial disparities in influenza cases persisted after equalizing vaccination coverage. The proportion of children in the population contributed to the number of influenza cases regardless of race. Differences in household composition may provide insight into racial differences and offer an opportunity to improve vaccination coverage to reduce influenza burden for both races.

Treatment of a Radiation-Associated Femur Fracture with an Intercalary Endoprosthesis
Authors: Johnson Joshua D. , Al Farii Humaid , Lewis Valerae O.
Published: November 2024

Case:

A 72-year-old woman with undifferentiated pleomorphic sarcoma of the thigh received neoadjuvant chemotherapy and radiotherapy. She underwent wide resection and was scheduled for prophylactic fixation of the femur. However, prophylactic fixation was deferred secondary to COVID-19 pandemic. Unfortunately, when stepping out of an elevator, she sustained femur fracture. The fracture was treated with a cemented intercalary endoprosthesis. Three-year follow-up reveals stable fixation without any failure.

Conclusion:

Postradiation fractures are challenging. Delayed union, nonunion, and infection are associated with internal fixation. To the best of our knowledge, this is the first report of intercalary endoprosthesis used for primary management of radiation-associated femur fracture.

Authors: Wilson Alan E. , Lau Emily N. , Moloney Gele B.
Published: November 2024

Case:

Extracapsular proximal femur fractures are a common injury that can be reliably treated with cephalomedullary nailing. We present 2 cases of atraumatic DePuy Synthes Trochanteric Fixation Nail Advanced implant failure through cephalic lag screw fenestrations in the setting of intertrochanteric fracture.

Conclusion:

Fenestrated lag screws inserted without cement augmentation may be susceptible to fatigue failure. Patients with unstable fracture patterns and other risk factors for delayed healing should undergo close clinical follow-up.
Intrathoracic Scapular Dislocation After Total Shoulder Arthroplasty
Authors: Post William R. , Kibler W. Ben
Published: November 2024

Case:

A 75-year-old woman status post total shoulder arthroplasty and posterior rib resection 29 years previously experienced a low-energy intrathoracic scapular dislocation (ISD). Closed reduction under anesthesia was unsuccessful, and she required open surgical repair performed by a novel modification of Kibler's technique for medial scapular muscle repair.

Conclusion:

This case is unique because increased range of motion after successful arthroplasty allowed her shoulder to flex forward enough to result in ISD. Successful surgical repair was performed by a technique previously not described.
Convergence of the Implicit Pressure-Explicit Saturation Method
Authors: Wattenbarger Robert A.
Published: November 2024

One well known finite-difference method of simulating reservoir flow is the Implicit Pressure-Explicit Saturation Method. This method is formulated to uncouple the pressure and saturation unknowns in such a manner that an implicit pressure equation can be solved that contains no unknown saturations. Then, given the pressure solution, the saturations can be solved explicitly, point by point. Various assumptions usually are made to linearize the coefficients of flow equations. These assumptions may or may not be improved by repetition of the solution (at each time step), depending upon the accuracy required. For many practical applications the Implicit Pressure-Explicit Saturation Method is a fast, accurate, and simple method.

Soil cadmium (Cd) pollution is a critical environmental issue that requires urgent remediation. Sedum alfredii, known for its high biomass, strong stress tolerance, and suitability for harvesting, serves as an excellent hyperaccumulator. This study used field experiments to investigate the enhancement of Cd phytoremediation in soil using three activators: citric acid (CA), malic acid (MA), and polyaspartic acid (PASP). The results showed that the biomass of Sedum alfredii was increased by 8.95%-28.37% by the addition of these activators, significantly boosting its Cd accumulation efficiency, with an average removal rate increase of 12%. Among all activators, CA exhibited the most substantial enhancement effect, with enrichment coefficients of 36.26% and 11.56% for the aboveground parts and roots of Sedum alfredii, respectively, and a 21.15% increase in Cd removal rate. Although PASP had less pronounced effect on biomass and Cd uptake, with decreases of 15.25% and 35.34% in the aboveground parts and roots, respectively, it significantly impacted soil Cd speciation and increased the activation rate by 20%.

Background
Cancer is one of the major health problems worldwide and medicinal plants constitute a common alternative for cancer treatment having no or less side effects. This study was aimed to assess total phenolic (TPC) and flavonoid (TFC) contents, antioxidant, biological activities (especially antibacterial, antifungal and anticancer) and chemical composition of methanol extract of M. napaulensis DC. bark (MNBM). This is the first study of evaluating its anticancer activity and chemical composition by LC-MS/MS analysis.
Methods
TPC, TFC, antioxidant, antimicrobial and anticancer activities were determined by Folin-Ciocalteu, AlCl3, DPPH, resazurin and MTT assays, respectively. Its metabolite profiling was done by LC-MS/MS analysis. The statistical significance of differences between test groups was analyzed by one-way ANOVA test.
Results
The preliminary phytochemical screening revealed the presence of various phytochemicals viz. alkaloids, steroids, glycosides, polyphenols, tannins, flavonoids, coumarins, terpenoids and quinone. MNBM showed 38.00 ± 1.50 mg GAE g− 1 dry sample as TPC; 35.04 ± 4.87 mg QE g− 1 dry sample as TFC and 212.97 µg/mL IC50 value (P < 0.05) as moderate antioxidant activity. MNBM showed minimal inhibitory concentration (MIC) values 100.22 mg/mL, 50.15 mg/mL and 25.08 mg/mL against S. aureus, E. coli and C. albicans, respectively as weak antimicrobial activity. It did not show any antibacterial effect against B. cereus and P. aeruginosa at 120 mg/mL. The anticancer activity of MNBM was moderate against human lung cancer cells A549 (228.97 µg/mL IC50 value) and human cervical cancer cells HeLa (367.72 µg/mL IC50 value) (P < 0.05). The LC-MS/MS analysis reported the presence of different anticancer compounds viz. dihydroberberine, d-berbamine, (S)-glaucine, protopine, grosheimin, mycophenolic acid, berberine, alpha-linolenic acid etc.
Conclusions
MNBM showed the dose-dependent moderate antioxidant, weak antibacterial, weak antifungal and moderate anticancer activity due to the synergistic effect of different phytochemicals and anticancer compounds.

Expansive soil is susceptible to water absorption, expansion, shrinkage, and cracking, leading to frequent road disasters. To address the issues of swelling, cracking, and low strength in expansive soil, sodium polyacrylate was utilized as a modifier for soil modification. The mechanical properties, expansion behavior, fracture characteristics, porosity changes and microscopic mechanisms of the modified expansive soil were described through physical property tests, expansion tests, mechanical tests, dry-wet cycle tests, and scanning electron microscope examinations. The results indicated a 52.14% decrease in liquid limit and a 77.36% decrease in plastic index; meanwhile the plastic limit increased by 20.83%. Additionally, the maximum dry density decreased by 5.11%, while the optimal water content increased by 28.47%. With an increase in modifier content up to 4%, both compressive strength and shear strength initially increased before decreasing again; reaching their peak at this level of content. The compressive failure type transitioned from E type to C type after modification. Vertical and lateral deformation were minimized with a shear content of 4%, resulting in an 86% reduction in axial deformation rate. The expansion rate decreased by 54.57%, along with a reduction of expansion force ranging from 15–57%. The cracks developed more slowly within the modified samples compared to unmodified ones, and their width decreased by 61.68% post-modification. SEM analysis revealed that hydrogel film filled between particles stretched and wrapped around them, making the soil structure more compact. PCAS pore analysis demonstrated varying degrees of changein porosity following modification, resulting in decreases in both to taland average porosity.
