Childbearing Motivation Questionnaire: cross-cultural adaptation and evidence of validation in Peru
Authors: Vásquez Varas Giuliana Violeta , Callegaro Borsa Juliane
Published: December 2024

Abstract Objective: This study aims to adapt and validate the Childbearing Motivation Questionnaire for use in Peru and to test the independence hypothesis between the two scales that compose it (Positive Childbearing Motivation and Negative Childbearing Motivation). Method: The process considered six steps: 1) Translations, 2) Synthesis of the translations, 3) Evaluation by judges, 4) Evaluation by the target audience, 5) Back-translation e 6) Validity analysis using factorial analysis, evaluation of internal consistency, and test of the independence of the scales through correlation analysis. The sample consisted of 1,054 Peruvians from 22 regions of Peru. Results: The Positive Childbearing Motivation scale showed a good fit for a bifactor, second-order structure, but the complementary bifactor indices indicate that the scale is mainly one-dimensional. The Negative Childbearing Motivation scale presented a unifactorial structure with adequate psychometric properties. Conclusion: The results show that the Childbearing Motivation Questionnaire is a valid instrument to measure the motivations to have children in Peru.

ABSTRACT Objective: to verify the effect of educational technologies on the quality of life of people with diabetes. Method: quasi-experimental study, before-and-after type, developed with a group of 34 people. Six interventions were carried out, in groups or individually, using educational technologies, such as clinical simulators and physical educational games. A questionnaire was used to extract sociodemographic and clinical data. To assess quality of life, the Diabetes Quality of Life Measure (DQOL) was applied at the initial (T0) and final (T1) moments. The paired Student’s t-test was used to compare the mean scores at T0 and T1, adopting a significance level ≤ 0.05. Results: the mean overall DQOL score revealed an increase from 142.7 (±11.8) to 162.2 (±9.1), with a statistically significant difference (p<0.001). The domains of satisfaction, impact and concerns related to diabetes also showed an increase with statistical difference. There was a significant reduction in postprandial blood glucose levels after the interventions, with a statistically significant difference (p<0.001). Conclusion: the use of educational technologies in educational interventions demonstrated an improvement in the quality of life of people living with diabetes.

Published: December 2024

ABSTRACT Water deficit induces morphophysiological adjustments in plants, what includes changes in biomass partitioning, non-structural carbohydrates and their ratios, reducing stomatal conductance and photosynthesis, and affecting the synthesis of transitory starch in leaves. This study analyzed the impact of soil water tensions on leaf non-structural carbohydrates and biomass partitioning during chickpea cultivation. The BRS Aleppo and BRS Toro genotypes were grown at soil water potentials of -30, -50, -70 and -90 kPa throughout the cycle. The water status, shoot and root dry mass, non-structural carbohydrate content and carbohydrate ratios were assessed. Decreasing the soil water potential reduced the relative water content and shoot dry mass of both genotypes. However, the BRS Toro’s root dry mass increased with the reduction in the soil water potential, as did the root:shoot ratio, in both genotypes. The genotypes also showed variations in the contents of soluble carbohydrates and starch in leaves, which increased with the reduction in the soil water potential, except for starch in leaves of the BRS Toro. These findings, especially variations in the carbohydrate ratios, suggest that the starch turnover is essential in chickpeas’ resilience to water deficit.

Authors: Reco Mariane de Oliveira Nunes , Hasebe Letícia Yoshiko , Almeida Priscila Rímoli de , Soares-Marangoni Daniele de Almeida
Published: December 2024

Resumo Introdução O índice de Apgar é o principal indicador de risco imediato ao nascimento no Brasil, e os general movements (GMs) são uns dos marcadores padrão-ouro para desfechos neuromotores. No entanto, não são encontrados estudos que tenham investigado diferenças diretas na qualidade dos GMs em relação ao Apgar. Objetivo Analisar se o índice de Apgar se relaciona à qualidade dos GMs em recém-nascidos pré-termo hospitalizados e comparar a presença de fato-res de risco entre aqueles de maior risco e um grupo controle de menor risco. Métodos Trata-se de um es-tudo observacional, por análise de prontuários. Foram elegíveis 30 recém-nascidos de 34,80 ± 1,41 semanas gestacionais, hospitalizados em unidade de cuidados intermediários neonatal e divididos em grupo de maior risco (Apgar ≤ 7 no 1º e 5º minuto, peso ao nascer < 2.500 gramas) e grupo controle (Apgar > 7 no 1º e 5º minuto, peso ao nascer ≥ 2.500 gramas). Foram coletados os resultados das avaliações dos GMs pelo método de Prechtl e os fatores de risco segundo o Sistema Único de Saúde. Resultados Não houve diferenças entre os grupos em relação aos GMs, porém houve diferenças quanto aos fatores biológicos, sendo que no grupo de maior risco houve maior presença de problemas no par-to, nascimento ou gravidez e icterícia grave. Conclusão O índice de Apgar não se relacionou com a qualidade dos GMs nos recém-nascidos pré-termo estudados. Entretanto, houve mais intercorrências gestacionais e peri-natais, além de icterícia grave, no grupo de maior risco, indicando possível relação entre esses fatores de risco.
Desigualdades socioeconômicas no local da morte: evidência para a Europa com base nos dados do SHARE
Authors: Lourenço Óscar , Portugal Silvia , Almeida Rita
Published: December 2024

Resumo O local de morte é considerado como um indicador de qualidade do fim de vida e pode ter consequências para a organização dos cuidados recebidos na última etapa da vida. Vários são os fatores que podem influenciar no local da morte de um indivíduo, dentre eles destacamos os fatores socioeconômicos. O objetivo da investigação é explorar a existência de desigualdades relacionadas com o local de morte para a população europeia com mais de 50 anos. Os dados para esta análise são provenientes do Survey of Health, Ageing and Retirement in Europe (SHARE). A variável de outcome é o local da morte, agregada em casa vs outro local; e para medir o estrato socioeconômico (ESS) dos indivíduos usamos as variáveis: rendimento individual equivalente; nível de educação; e existência de herança no momento da morte. O modelo estatístico adotado é o modelo logístico, com a apresentação e interpretação do parâmetro Odds-Ratio (OR), ou razões de possibilidades, para a morte em casa vs outros locais. Cerca de 34,3% dos óbitos na Europa ocorreram no domicílio, e os 65,7% restantes ocorreram numa instituição, na sua maioria no hospital. Os dois países em que é mais frequente morrer em casa são a Bulgária (73,5%) e a Romênia (68,9%). No polo oposto, os países onde é menos provável morrer no domicílio são o Chipre (10,9%) e a Finlândia (15,4%). Indivíduos de menores rendimentos apresentam mais chances de morrer em casa em relação aos de maiores rendimentos, e a educação não se revelou uma determinante do local da morte. Concluímos, assim, pela existência de desigualdades socioeconômicas associadas ao rendimento nas chances de falecer no domicílio.
Enfoques e abordagens de artigos sobre divulgação científica publicados em periódicos brasileiros
Authors: Hungaro Ana Regina de Oliveira , Pugliese Adriana
Published: December 2024

Resumo A Divulgação Científica (DC) desempenha um papel crucial no desenvolvimento social, cultural e econômico de uma sociedade. No Brasil, seu histórico é antigo, mas atingiu crescimento contínuo, que pode ser observado no crescente número de artigos publicados sobre o tema nos últimos anos. Diante desse cenário, este trabalho teve como objetivo mapear como a DC tem sido abordada em publicações, no período de 2014 a 2021, em seis periódicos acadêmicos (Anais da Academia Brasileira de Ciências, Revista Brasileira de Pesquisa em Educação em Ciências, Ciência & Educação, Educação e Pesquisa, Educação & Realidade, e Revista de Ensino de Ciências e Matemática) classificados como estrato A no Programa Qualis da CAPES. Foram analisados o Estado do Conhecimento nas publicações encontradas e o material submetido à Análise de Conteúdo proposta por Bardin (2011). Ao todo, foram selecionados 51 artigos relacionados à Divulgação Científica. Nesse corpus de artigos, foram observados: 1) a distribuição dos artigos ao longo dos anos e como o tema tem sido tratado; 2) o número de parcerias entre instituições brasileiras e estrangeiras; 3) a presença das grandes áreas do conhecimento (Física, Química, Biologia e Ciências); e 4) o comportamento das revistas durante o período pandêmico, entre 2020 e 2021. Por fim, em uma análise qualitativa, foram criadas oito categorias que possibilitaram identificar o predomínio da utilização da DC em sala de aula, na forma de recurso didático, enquanto outras áreas mostraram-se com lacunas. Nossa intenção não foi esgotar o que se sabe sobre o tema, afinal, a maior parte das publicações sobre DC está pulverizada, mas trazer um panorama geral da temática. Nesse sentido, acreditamos no papel dos periódicos específicos da área, bem como no financiamento de projetos que podem contribuir com a maturidade da DC.
O ensino da solidão: os “métodos selvagens” do professor Foucault
Authors: Vinci Christian Fernando Ribeiro Guimarães
Published: December 2024

Resumo Esse ensaio pretende recuperar a compreensão foucaultiana acerca do ofício docente, bem como sua influência nas metodologias de trabalho adotadas por Michel Foucault em suas aulas. Para tanto, procederemos com a análise de algumas intervenções do pensador francês nos cursos ministrados por ele no Collège de France, mormente os momentos nos quais expressava seu desconforto com certos ritos institucionais que impediam um diálogo efetivo com seu público, afora comentários esparsos sobre o ofício docente em entrevistas concedidas nas décadas de 1970 e 1980, nas quais Foucault não apenas expunha o seu descontentamento com a concepção educacional francesa como apresentava um esboço daquilo que acreditava ser a função de um professor. Se, para Foucault, competia ao professor promover um tensionamento de nossos modos de pensar e agir, recuperar esses registros possibilitar-nos-ia apreender como essa compreensão modulou a sua própria performance docente. Uma performance marcada pela adoção de “métodos selvagens” de trabalho, ou seja, pequenos mudanças na estruturação de seus cursos voltadas para a produção de um tempo qualitativamente diferente, o tempo da problematização. Um tempo voltado contra o tempo presente e a favor de um porvir, um tempo cuja paga é única e exclusivamente a solidão e o silêncio.

ABSTRACT Cervical endoscopy is one of the most advanced stages in the learning curve for endoscopic techniques in spine surgery, requiring precise control of instruments to avoid severe complications. We report the case of a 53-year-old female patient with bilateral cervicobrachialgia and myelopathy caused by severe central stenosis at C2-C3. After the failure of conservative treatment, an endoscopic posterior over-the-top cervical decompression was performed. The surgery was completed, with significant improvement in pain and neurological function. At six months of follow-up, the patient showed an increase in her mJOA score, indicating improved functionality. This case demonstrates that the endoscopic technique can be effective and safe in treating cervical stenosis with spinal cord compression and myelopathy. However, further studies are needed to confirm its efficacy compared to other surgical approaches. Level of Evidence IV; Case Report.

ABSTRACT Endoscopic spine surgery has been widely employed in the treatment of compressive conditions such as disc herniations, facet cysts, and stenoses. Despite being a minimally invasive technique, the increased number of procedures is accompanied by a rise in complications, especially during the learning curve. We report the case of a 48-year-old female patient who underwent lumbar endoscopic discectomy and developed Complex Regional Pain Syndrome (CRPS) postoperatively, a rare complication not previously described in the literature for this type of surgery. The patient had chronic lumbar radiculopathy, which had worsened over the last six months, and after failing conservative treatment, surgery was chosen. Postoperatively, the patient developed intense pain, edema, allodynia, and vasomotor signs, leading to the diagnosis of CRPS. Treatment included physiotherapy and sympathetic block, resulting in significant improvement. The development of CRPS may be associated with factors such as manipulation of the dorsal root ganglion and nociceptive sensitization. This case highlights the importance of recognizing CRPS as a possible complication in endoscopic spine surgery and the need for a multidisciplinary approach for proper management. Level of Evidence IV; Case Report.

ABSTRACT Extruded disc herniations with a high degree of caudal migration represent a surgical challenge due to the location of the extruded fragment in a difficult-to-access area known as the “hidden zone”. Traditional endoscopic approaches, such as interlaminar and transforaminal routes, can be challenging in these cases. This study aims to report a case of a transpedicular endoscopic approach in the treatment of an extruded disc herniation with high-grade caudal migration (Lee’s zone 4). We present a 52-year-old male patient with intense pain radiating to the right lower limb and motor deficit. After the failure of conservative treatment, a transpedicular endoscopic discectomy was performed at L4-L5. The procedure was successfully completed without complications, resulting in immediate pain relief and significant functional recovery, maintained over 24 months of follow-up. This case demonstrates that the transpedicular endoscopic approach can be an effective and safe alternative for treating extruded disc herniations with high caudal migration, provided it is performed by experienced surgeons with appropriate planning.

The influence of combustion temperature on the phase and morphological compositions of Si3N4‒Yb2O3 composites obtained by the SHS method
Authors: Shibakov I. A. , Zakorzhevskii V. V.
Published: December 2024

The effect of combustion temperature on the phase composition and morphology of particles of SHS composites of the composition Si3N4‒Yb2O3 was studied. The combustion temperature was controlled using the silicon content in the reaction mixture.  It  was  found that with an increase in the synthesis temperature, the content of α-Si3N4 decreases. Silicon ytterbium oxynitride is formed as a secondary phase. The morphology of the particles of the composition changes with an increase in the combustion temperature from the equiaxed form of α-Si3N4 to columnar crystals of β-Si3N4. Ill. 3. Ref. 7.

Published: December 2024

The physical and mechanical properties of concrete modified with superplasticizers based on polycarboxylate esters were studied. The primary focus was on the development and optimization of concrete mix compositions containing import-substituting superplasticizers made from domestic raw materials and secondary materials. Initially, the effect of the superplasticizer SDj-1 on the normal consistency of the cement paste was investigated using a Vicat apparatus. The optimal content of SDj-1 in the cement paste was 0,6 % of the cement mass. The effect of superplasticizer SDj-1 on the workability of the concrete mix was determined by the slump test. The results of experimental studies showed that the use of superplasticizer SDj-1 significantly reduces the watercement ratio and improves the rheological properties of concrete mixes, which in turn leads to increased strength and durability of the concrete.

Faktore wat tot die totstandkoming van die Mid-deleeuse universiteit as instelling bygedra het
Authors: Diedericks M
Published: December 2024

Deur die eeue heen moes instellings soos universiteite dikwels hervormings ondergaan as gevolg van beduidende veranderinge of onstabiliteit. Die einde van die 20ste eeu is gekenmerk deur 'n nuwe golf van hervorming, wat steeds voortduur. Hierdie hervormings is aangepor deur faktore soos die massifikasie van universiteite, oproepe tot dekolonialisering en tegno-logiese veranderinge in die 21ste eeu. Die vraag, Wat is 'n universiteit? of Wat behoort 'n universiteit te wees?, het as gevolg hiervan ontstaan. Verder het die hervormingstydperk aan-leiding gegee tot indringender geskiedkundige studies oor die ontstaan en ontwikkeling van universiteite.
Om die totstandkoming van die eerste universiteite beter te verstaan, speel stigtings-dokumente en agtergrondinligting van die universiteit 'n belangrike rol. Wanneer die wese van die universiteit ondersoek word, is dit belangrik om die ontstaan van die Middeleeuse universiteit te bestudeer. Wat Middeleeuse universiteite uniek maak, is die ontwerp van 'n model wat wêreldwyd in gebruik geneem is. Teen dié agtergrond is die navorsingsvraag van hierdie artikel: Wat is die faktore wat tot die totstandkoming van die Middeleeuse universiteit as instelling bygedra het?
Verskeie faktore, soos die gildestelsel, ekonomiese welvaart en intellektuele ontwikkeling in Europa gedurende die laat Middeleeue, erkenning van die universiteit deur owerhede en die stabilisering van die universiteit deur die formulering van reëls en statute oor hoe 'n universiteit moet funksioneer, is met behulp van navorsing geïdentifiseer. Hierdie faktore was ook aanwesig tydens die stigting van een van die eerste universiteite, en die effek daarvan op byvoorbeeld een van hierdie oudste universiteite, naamlik Bologna word ook in hierdie artikel bespreek. Faktore wat bygedra het tot die totstandkoming van die Middeleeuse universiteit is steeds van toepassing op moderne universiteite en behoort as minimum vereistes beskou te word.
'n Netwerkwetenskaplike oorsig en verkenning van netwerke rakende die ontlaeringprojek
Authors: Senekal B
Published: December 2024

Die Ontlaeringprojek is in 2018 geloods in 'n poging om gesprekke rondom die uitbreiding van Afrikaans se kontekste te bemiddel. Drie kollokwiums en twee spesiale vaktydskrifuitgawes het gevolg, sowel as 'n polemiek op LitNet. In die huidige studie word netwerke rakende die Ontlaeringprojek ontleed: die kollokwiumnetwerk (wat bestaan uit rolspelers en die kollokwiums waarby hulle betrokke was), die mede-outeurskapnetwerk (wat bestaan uit mense wat bydraes tot die twee spesiale vaktydskrifuitgawes gelewer het), die verwysingsnetwerk (wat bestaan uit outeurs en die bronne waarna hulle verwys het) en die woordkovoorkomsnet-werk (wat bestaan uit woorde wat gereeld saam in opsommings van artikels in die twee spesiale vaktydskrifuitgawes voorkom). Netwerkmaatstawwe wat gebruik word, sluit in digtheid, verbinde komponente, modulariteit, k-kerne en eksentrisiteit, tesame met netwerkvisualiserings. Daar word aangetoon dat al hierdie netwerke baie heterogeen is, en sleutelnodusse - betrokkenes by kollokwiums, sleutelbronne en sleuteltemas - word uitgelig. In die geheel word daar bevind dat die diversiteit van netwerke en die aard van sleutelnodusse die Ontlaeringprojek se oogmerke weerspieël.
Changes in cognitive functional performance and basic activities of daily living in patients with traumatic brain injury after two methods of cognitive retraining
Authors: FranzsenI D , Msengana Z
Published: December 2024

INTRODUCTION: Evidence supports a bottom-up approach to assist in addressing functional cognitive deficits in patients with traumatic brain injury (TBI). There is however, little evidence supporting the use of online programmes for this purpose. The aim of this research was to describe the outcomes for cognitive functional performance and basic activities of daily living (bADL) or self-care functioning after cognitive retraining using an online programme versus task-oriented intervention for patients with acute mild and moderate traumatic brain injury.
METHODS: A quantitative, quasi-experimental, longitudinal research design was used for determining within-group and between-groups changes for cognitive functional performance and bADL functioning in two sample groups with mild to moderate TBI. Intervention using an online programme (n=7) or task-oriented activities (n=15) was evaluated at three assessment intervals: on recruitment into the study (Assessment 1), on completion of inpatient hospital intervention (Assessment 2) and after four weeks of home programme intervention and fortnightly outpatient intervention (Assessment 3).
RESULTS: Results for both groups showed a statistically significant change for cognitive functional performance assessed on the Bay Area Functional Performance Evaluation (BaFPE) while the task-oriented cognitive training group also achieved a statistically significant change in bADL scores during the first inpatient assessment period. Only the online programme group had statistically significant improvement during the home programme in the third assessment period.
CONCLUSION: Cognitive retraining using an online programme or task-oriented activities resulted in positive change in a therapist-directed inpatient programme but a structured, graded, online programme was more effective in supporting significant improvement in cognitive functional performance when used together with an outpatient home programme.
IMPLICATIONS FOR PRACTICE
• Cognitive retraining using an online programme or task orientated activities have a positive outcome for cognitive functional performance in patients with mild or moderate TBI in a therapist directed inpatient intervention.
• A task orientated approach for cognitive retraining appears to have positive effect on bADL outcomes.
• Cognitive retraining using an online programme intervention should be considered as a home programme to improve cognitive functional performance in patients with mild or moderate TBI.

France’s cycle L’Étui de nacre as an example of such case. We argue that this title is cryptic and, in the absence of the author’s comments, needs interpretation from the reader. To understand the title and its function, we look at its both parts (étui and nacre)
in the context of various discourses and traditions (myths, religions), paying special attention to France’s own works, in order to find a clue to the cryptic title. Although the image of a container could be used as a traditional metaphor for a collection of literary works, France’s choice of the lexeme makes this hardly conceivable as the word étui requires a complement which is missing from the title, so it is not known what the container is designed for, not to mention whether it is empty or full, open or closed, etc. Thus, the image of a container, important for France’s oeuvre, becomes significant in itself, as it continuously appears in all the parts of the cycle, acquiring several distinct meanings of keeping, secrecy, and memory. France also implies several ideas related to mother-of-pearl, being attracted by its aesthetic and literary associations, as well as its polysemy and ambiguity, the awareness of which is obvious from the analysis of his prose. The religious associations of the image that are often used to refer to Logos foreground the very idea of baptism and draw the reader’s attention to characters’ names in the cycle. Its mythological potential is realised differently in the parts devoted to different cultures ranging from Venus to Virgin Mary, and ultimately to the woman in general. Nacre also introduces the image of pearl, which France traces in Dante’s Divine Comedy, which, through a complex net of associations, embodies a universal verity comprised of numerous individual and often conflicting truths. The semes that are foregrounded in the cycle with the help of the title are those of whiteness and oscillation, with a background of meanings from several cultures. This is especially important for France, as the stories of L’Étui de nacre show the same objects or actions
from different angles, and the author’s position is hardly conceivable. Both parts of the title can serve as references to myth and Christianity, as well as to several central concepts of the cycle, such as the complex nature of femininity, the relations between
love and death, reason and faith, and the meaning of history. The intentionally elusive image implied by the title aims to reflect the ambiguity of these concepts, the unattainability of an ultimate and exclusive interpretation of the author’s position.
Bank Secrecy: a Look at Modern Trends from a Theoretical Standpoint
Authors: Vishnevsky Alexander
Published: December 2024

Bank secrecy has long been recognized as one of the fundamental legal constructions in banker-customerrelationships. Recent developments in legal regulation of it show that bank secrecy is subject to more andmore limitations, i.e. more and more authorized bodies may have access to the relevant information and,moreover, in some cases the banks are obliged to inform the authorities about clients’ transactions evenwithout any request. Many scholars consider these developments as a limitation of bank secrecy whicheventually may lead to its “death”. The author argues that such an assessment is based on a one-sided approachto bank secrecy as a fundamental right of the bank’s client. As a general rule, bank secrecy of thisnature is understood to be one of the components of an individual’s right to privacy, or — in the case of alegal entity — as one of the fundamentals of the legal status of a legal entity. Although such an approach isacceptable within a positivistic view on the legal theory, the author argues that a broader view on the matteris justified when the legal nature of bank secrecy is understood as a legal construction aimed at finding anoptimal balance between private and public interests involved in the confidential sphere of banker-customerrelationships. As a result the latest developments may be seen as attempts to find a new balance, thebalance between private and public law aspects of bank secrecy which will be more adequate taking intoconsideration the realities of the contemporary banking and financial environment.

A Reliable Voltammetric Method Utilizing the Effect of an Anionic Surfactant for the Determination of Leuprolide
Authors: Aksöz Begüm Evranos , Topal Burcu Dogan
Published: December 2024

Leuprolide acetate is a synthetic gonadotropin-releasing hormone agonist used in the treatment of central precocious puberty, uterine fibroids, endometriosis, and prostate cancer. In this study, the rapid, simple, environmentally friendly, and sensitive voltammetric method was developed for the quantification of leuprolide acetate in the presence of an anionic surfactant on a glassy carbon electrode. The effect of surfactant types, pH, and scan rate on the voltammetric response of leuprolide acetate were evaluated. Using square wave voltammetry, two anodic peaks were observed at 0.81V and 1.26 V for the glassy carbon electrodes at pH 3.70 (acetate buffer solution). The oxidation peak currents of leuprolide acetate were enhanced in the presence of 8.0 × 10–2 mM sodium dodecyl sulfate. The sodium dodecyl sulfate monomer can be drawn to amino moieties in the drug structure through electrostatic interaction. The voltammetric behavior of leuprolide acetate exhibited irreversible and diffusion-adsorption mix-controlled processes by cyclic voltammetry. All stripping conditions and square wave voltammetric parameters were optimized at pH 3.21 (phosphate buffer). Under optimized conditions, the proposed method exhibits linearity in the concentration range of 3.64 × 10–6–2.00 × 10–4 mM with a nano-level detection limit of 4.70 × 10–7 mM by square wave adsorptive stripping voltammetry. The developed method was applied for the determination of leuprolide acetate in a pharmaceutical dosage form with a satisfactory recovery of 97.72%.

Chorionic Villi with Placental Hypoplasia
Authors: Gansburgsky AN , Yaltsev AV
Published: December 2024

The structure and proliferation of endothelial and muscle cells of the chorionic veins of the underdeveloped placenta were studied. Histological, histochemical, and morphometric studies of the fetal membrane of the placenta of 36 placentas of 280-300 g at 39-40 weeks of pregnancy were carried out in comparison with 15 placentas of 450-500 g. The Ki-67 proliferation marker (Ventana, USA) was studied immunohistochemically with the determination of the proliferation index on the Roche Benchmark XT Ventana (USA) immunohistostainer by counting 1000 nuclei of endothelial cells and myocytes in capillaries, venules, and veins of the stem, intermediate and terminal villi. The outer and inner diameters of the veins were measured. The data were processed using the variation statistics method.
The stem villi are supplied with a vein, artery, and capillaries. Amygdaloid veins are present at the bases, venules are on the surface of the intermediate villi. Capillaries are distinguished in the terminal villi. In hypoplasia, sphincter-like and valve-like structures are formed in the veins. Subendothelial sphincter rings of circularly located myocytes protrude into the lumen. Intimal cushions are obturator longitudinal layers of myocytes. Between the sphincters, the veins are dilated. Valvelike elements with myocytes and collagen fibers are found in small veins. These formations ensure blood distribution in the underdeveloped placenta and a decrease in trophic and oxygen starvation of the fetus. Hypoplasia is accompanied by venodilation with an increase in the external and internal diameters and an increase in the proliferation of cells of the chorionic veins.

Appropriate maps have been developed for objects that require creation or reconstruction.
Noise Analysis of Distributed Acoustic Sensing (DAS) Data in Borehole Installations

Published: December 2024

Distributed acoustic sensing (DAS) is a technology that is revolutionizing seismic data acquisition, particularly in borehole installations. Acting as a dense array of receivers, DAS provides high coverage, revealing time-depth patterns that are often hidden in data acquired with traditional seismometers. Its resilience to extreme temperature and pressure conditions, in which standard instrumentation typically fails, makes DAS reliable for microseismic monitoring operations in deep boreholes in geothermal environments. However, DAS faces challenges such as a lower signal-to-noise ratio compared to conventional geophones. DAS requires advanced denoising workflows in environments with high background noise, for example, from anthropogenic activities. A broader understanding and characterization of the noise observed in optical fibers is thus necessary and is still lacking. In this work, we aim to address this gap by analyzing noise data acquired from a fiber-optic cable installed in a monitoring well at the Utah Frontier Observatory for Research in Geothermal Energy Enhanced Geothermal System pilot project site in southcentral Utah, United States. Our proposed workflow combines power spectral density and phase analysis to assess the modulation of noise over time and depth for different frequencies and consequently to differentiate noise originating by anthropogenic sources at the surface from those further away from the industrial site. In addition, our analysis highlights noise components that may be related to instrumental noise from the interrogator, contributing to future noise mitigation strategies. This is further demonstrated through a direct comparison with noise observed by geophones coupled with the optical fiber in the same monitoring well.
