Published: December 2023

Nesse artigo, os métodos Talbot e Talbot-Racional são apresentados como alternativas numéricas para a inversão da Transformada de Laplace, especialmente para problemas em que a execução de forma analítica dos processos se torna muito difícil. Testes foram realizados no sentido de investigar o potencial de resolução dessas técnicas ao serem aplicadas em um problema de difusão de mercúrio no ambiente aquático. Com base nos resultados obtidos, concluiu-se que o algoritmo Talbot foi o mais eficiente para a inversão numérica da solução no referido problema. Já o método Talbot-Racional, mesmo usando uma quantidade maior de termos no somatório, não demonstrou desempenho equivalente no processo. Entretanto, destaca-se que tal aproximação melhora com o aumento do valor de dentro de certos intervalos.

Abstract
The Mogou site in Lintan, Gansu, has yielded the largest collection of Qijia culture bronze artifacts discovered to date. More than 300 bronze artifacts were unearthed, including new forms such as bracelets, neck ornaments, and earrings with trumpet-shaped ends, reflecting the advanced bronze production technology during the late Qijia culture period. This paper presents an analysis of 146 bronze artifacts from the Mogou site, conducted through metallographic microscopy and SEM-EDS analysis. Our results indicate that a relatively high percentage of small ornaments, primarily made of tin bronze, underwent hot forging and cold working, while tools, primarily made of copper and tin-bronze, were typically cast. Furthermore, this study reveals the concurrent existence of leaded tin bronze and arsenical bronze during the late Qijia culture period, suggesting influences from multiple metallurgical systems.

Abstract
What factors may influence word learning from reading has long been a research topic of interest without definitive results. To contribute to the understanding of this important topic, this study, with the design of the same group of participating students with different proficiency levels and treated with different conditions, investigates the effects of context (reading the same story repeatedly vs. reading several different stories), story-type (humor vs. non-humor stories), and language proficiency on Chinese EFL students’ word learning in the form of pseudowords (measured by two different types of vocabulary immediate posttests) and word retention (assessed by the same but delayed vocabulary posttests). Mixed effects model analyses show multiplex effects of the variables and their interactions across the conditions examined. First, while language proficiency had a significant modulating effect supporting previous research findings, the effects of the context and story-type variables differed across vocabulary test types and testing time. In the meaning-recall test, the reading-different-stories condition yielded significantly better learning than the reading-the-same-story-repeatedly condition. However, in the form-recognition test, the effect of context was conditioned by story-type and proficiency with lower-proficiency students gaining more in reading humor stories in the same-story-repeatedly context while higher-proficiency students performed better in the reading-different-stories context. Overall, higher-proficiency students were less sensitive to the context and story-type variables than lower-proficiency students. Pedagogical and research implications are also discussed.

Abstract

Objectives
Adenomyosis is associated with unfavorable perinatal outcomes, and recent case reports show that some women with adenomyosis experience pain at the adenomyosis lesion during pregnancy and have detrimental perinatal outcomes. This study aimed to clarify the clinical characteristics of this pain and perinatal outcomes associated with this phenomenon.

Methods
This was a single-center retrospective analysis of pregnant women with adenomyosis. The incidence of pain onset at adenomyosis lesions, defined as persistent pain at the adenomyosis site with administration of analgesics for pain relief, and its association with perinatal outcomes were analyzed.

Results
Among 91 singleton pregnancies with adenomyosis, 12 pregnancies (13.2 %) presented with pain. One pregnancy resulted in second-trimester miscarriage, and 5 of the 11 pregnancies (45 %) developed preeclampsia, which resulted in preterm delivery, and 3 of the 12 pregnancies (25 %) achieved term delivery. The incidence of preeclampsia and preterm delivery was higher in those who experienced pain than in those without (45 % [5/11] vs. 15 % [11/74]; p<0.05, and 73 % [8/11] vs. 34 % [25/74]; p<0.05, respectively). Among women with pain, the maximum C-reactive protein level was significantly higher in women who developed preeclampsia than in those who did not (5.45 vs. 0.12 mg/dL, p<0.05).

Conclusions
Our study revealed that adenomyosis can cause pain in over one of eight pregnancies with adenomyosis, which may be associated with the increased incidence of preeclampsia resulting in preterm delivery. Women with pain, especially those with high C-reactive protein levels, may be at high risk for future development of preeclampsia and consequent preterm delivery.

Abstract

Objectives
Among patients with preterm labor and intact membranes (PTL), those with intra-amniotic infection (IAI) present the highest risk of adverse perinatal outcomes. Current identification of IAI, based on microbiological cultures and/or polymerase chain reaction amplification of the 16S ribosomal RNA gene, delay diagnosis and, consequently, antenatal management. The aim to of the study was to assess the performance of a multivariable prediction model for diagnosing IAI in patients with PTL below 34.0 weeks using clinical, sonographic and biochemical biomarkers.

Methods
From 2019 to 2022, we prospectively included pregnant patients admitted below 34.0 weeks with diagnosis of PTL and had undergone amniocentesis to rule in/out IAI. The main outcome was IAI, defined by a positive culture and/or 16S ribosomal RNA gene in amniotic fluid. Based on the date of admission, the sample (n=98) was divided into a derivation (2019–2020, n=49) and validation cohort (2021–2022, n=49). Logistic regression models were developed for the outcomes evaluated. As predictive variables we explored ultrasound cervical length measurement at admission, maternal C-reactive protein, gestational age, and amniotic fluid glucose and matrix metalloproteinase-8 (MMP-8) levels. The model was developed in the derivation cohort and applied to the validation cohort and diagnostic performance was evaluated. Clinical management was blinded to the model results.

Results
During the study period, we included 98 patients admitted with a diagnosis of PTL. Of these, 10 % had IAI. The final model included MMP-8 and amniotic fluid glucose levels and showed an area under the receiver operating characteristic curve to predict the risk of IAI of 0.961 (95 % confidence interval: 0.860–0.995) with a sensitivity of 75 %, specificity of 93.3 %, positive likelihood ratio (LR) of 11.3 and negative LR of 0.27 in the validation cohort.

Conclusions
In patients with PTL, a multivariable prediction model including amniotic fluid MMP-8 and glucose levels might help in the clinical management of patients undergoing amniocentesis to rule in/out IAI, providing results within a few minutes.

After introducing this new family, we gave the motivations that led us to this end and the basis of the new family obtained, followed by the mathematical properties related to the family. Then, we presented the statistic order, the quantile function, the series expansion, the moments, and the entropy (Shannon, Reiny, and Tsallis), and we estimated the parameters by the maximum likelihood method. Finally, using real data, we presented numerical results through data analysis with a comparison of rival models.

Abstract
Dorsal root injury usually leads to irreversible sensory function loss and lacks effective treatments. (−)-epigallocatechin-3-gallate (EGCG) is reported to exert neuroprotective roles in the nervous systems. However, the function of EGCG in treating dorsal root injury remains unclear. Hence, we built the dorsal root crush injury (DRCI) rat model to be treated with EGCG, followed by the western blot, Enzyme-linked immunosorbent assay, and sensory behavior tests. We observed that EGCG can upregulate the Lysine acetyltransferase 6A (KAT6A) level and inhibit the pyroptosis, indicated by downregulated gasdermin-D, caspase-1, and interleukin 18 protein levels, and alleviate the neuropathic pain, indicated by the decreased paw withdraw threshold in Plantar test and decreased paw withdraw latency in von Frey test, and downregulated calcitonin gene-related peptide, nerve growth factor, and c-Fos protein levels. But EGCG cannot alleviate the neuropathic pain when the KAT6A was inhibited by CTX-0124143 and pyroptosis was activated by Miltirone. These combined results indicated that EGCG can promote the sensory function recovery in rats after DRCI via upregulating KAT6A and inhibiting pyroptosis, laying the foundation for EGCG to be a novel candidate for the treatment of dorsal root injury.

Published: December 2023

Introduction. The article deals with the problem of selecting the content of the training of future teachers of general technical disciplines. It is proved that in conditions of multi-vector technical development, and turbulence associated with the transition to a multi-polar world order, the content of this training should change rapidly. Not only the given invariant of this content is important, but also the methodology of its formation.Aim. The present research aims to formulate the problem of developing the content for technical teacher training.Methodology and research methods. The developed methodology foundations for the selection of optimal content for technical teacher training are based on activity, competence-based, transfessional and transprofessional approaches. The empirical base was obtained using a distance questionnaire to technical teachers from 26 universities. The following theoretical methods were applied: retrospective analysis of the working conditions of teachers of technical disciplines; analysis of scientific and methodological literature on the problem of combining subject-professional and pedagogical training of a technical teacher; analysis of disciplines from professional training programmes in the Russian universities.Results. The analysis of vocational training programmes of technical and pedagogical universities made it possible to compare them with each other and to correlate the disciplines of the general professional block and elective courses to the main current directions of the Russian technical development in the current conditions. This made it possible to identify the content of the professional activity of the future technical teacher, as well as to indicate the possibilities for changing this content both in technical and pedagogical universities in order to more accurately match it with the existing tasks of technical development of the state. As a result of a retrospective analysis, a historically formed “portrait” of a technical was described. The following problems were indicated: “physical and technical snobbery” as unwillingness to enter the humanities and pedagogical field of professional activity from the physical and technical content of their subject; a low level of methodological knowledge and skills; lack of erudition in technical fields among young teachers; low professional self-esteem.Scientific novelty consists in the fact that for the first time the analysis of the disciplines of the general professional module and elective courses of technical and pedagogical universities of Russia revealed their correlation with the main directions of the development of science, technology and engineering.Practical significance. The conducted research allowed the authors to raise questions about the selection of the content of technical teacher training. This should help in the formulation of the principles of content selection to develop its methodology.

Introduction. Multiple studies advocate an importance of spatial abilities (SA) for educational and occupational success, especially in STEM. Recently an Online Short Spatial Ability Battery (OSSAB) was developed and normed for SA testing in adolescents. The battery includes mechanical reasoning, paper folding, pattern assembly, and shape rotation tests. The battery has shown good psychometric characteristics (high reliability and validity, low redundancy, discriminative power), and is available in open access and free to use.Aim. The present research aims: 1) to examine the applicability of the OSSAB for university student testing; 2) to describe its psychometric properties and structure; and 3) to investigate links between SA and educational performance.Methods. A total of 772 university students (aged from 18 to 26, mean age (SD) = 19.55 (1.51), 63.1% females) participated in the study. Participants provided information about their age, gender, university major, and academic achievement, and completed a battery of tests that included the OSSAB tests.Results. The study reports psychometric norms for using the OSSAB in university students. Students’ performance in the OSSAB was similar to that shown in previous research in adolescents in terms of means and variance. The OSSAB showed adequate psychometric properties in this sample: no floor or ceiling effects; low redundancy; moderate to high internal consistency; high discriminative power across university majors; and high external validity. The results indicated that around 6% of the students showed very high levels of SA (higher than 1.5 SD above the mean), and around 8% of students showed very low levels of SA (lower than 1.5 SD below mean). In addition, the OSSAB scores were linked to educational profile choice and exam scores, with small-to-medium effect sizes.Scientific novelty. The study provides psychometric norms for a short online open measure of spatial ability in university students.Practical significance. The OSSAB can be used to provide individual recommendations to students (e.g. SA training), to identify spatially gifted students, and for research purposes in university contexts.

Published: December 2023

Primary ciliary dyskinesia (PCD) is a rare hereditary disease from the group of ciliopathies with extensive locus and allelic heterogeneity (ORPHA 244, 98861; OMIM 242650, 244000). This disease is inherited by autosomal dominant or autosomal recessive type and, less often, by X-linked type (OMIM 300424). Retinitis pigmentosa develops in the X-linked PCD variant. The overall minimum global prevalence of PCD according to European data is 1 : 7554. There is no generally accepted classification of PCD in the international classification of diseases (ICD), 10th revision. PCD is not presented in ICD-10 as a separate medical entity, and the code Q32.4 – Other congenital bronchial anomalies – is used for coding. In the new edition of ICD-11, the code LA75.Y is highlighted – Other specified structural abnormalities of the lungs.Primary ciliary dyskinesia. However, there is no generally accepted classification of PCD. The aim of the study was to develop a classification of primary ciliary dyskinesias to improve the efficiency of medical care for patients during follow-up.Methods. European and Russian clinical recommendations, as well as ICD 10th and 11th revision, Classification of Respiratory Insufficiency (2020), Order of 27.08.19 No.585n “On classifications and criteria used in the implementation of medical and social expert assessment of citizens by federal state institutions of medical and social expert assessment” (as amended on 06.10.21) were used to create the classification.Results. The classification of PCD was created and can be recommended for use in clinical practice. The classification was based on the presence or absence of the Sievert – Kartagener syndrome (complete, not complete), as well as clinical and instrumental characterization of bronchopulmonary changes based on the presence of chronic obstructive bronchitis, bronchiectasis (specifying the type and localization), pneumofibrosis with the process activity (exacerbation, remission), and the degree of respiratory failure. It is recommended to take into account extrapulmonary manifestations of PCD, such as rhinosinusitis, media otitis, congenital heart defect, and complications. It is recommended to use the PICADAR (PrImary CiliAry DyskinesiA Rule) score and to include the results of video microscopy, DNA diagnosis, and microbiological examination in the diagnosis.Conclusion. The application of the proposed classification can be useful in the dynamic observation of the patient, therapy and in the conduct of medical and social expert assessment.
