To propose methods and means aimed at eliminating situations and processes that adversely affect the operation of shipboard electrical power systems when laying pipelines.METHODS. For observation and research, the unified electrical power systems with electric rudder propellers and a system for laying an underwater pipeline of the "Seven Vega" cable layer was considered. Collected information on all the main electrical systems of the vessel "Seven Vega". Experimental studies were carried out aimed at studying the operating modes of the electrical power system during the laying of pipelines.RESULTS. Experimental oscillograms of currents of parallel operating diesel-generator sets in different modes have been obtained. The existence of power exchange oscillations during the operation of the unified electric power system of the cable-laying ship “Seven Vega” is noted. The data on the negative influence of power oscillations on the operation of tensioners during the laying of underwater pipelines were obtained.CONCLUSION. The use of sea-going vessels with dynamic positioning for laying pipelines and performing oil and gas production operations requires ensuring the operation of their electrical power systems. To ensure the high-quality operation of tensioners in pipeline laying systems, it is necessary to ensure the adjustment of their regulators and to exclude the occurrence of power exchange oscillations during parallel operation of generator sets.

Published: April 2022

The way we experience our cities is not neutral: women and men experience it differently, depending on factors such as where they live, the social group which they belong to, the gender roles assigned, and intersectionality. Urbanismo Mujeres y Ciudad en Latinoamérica is a platform that works with qualitative methodologies with gender and feminist perspective.This article presents a methodological proposal to answer the central question: How is the urban experience of women in two Latin American cities: Mexico City and Santiago de Chile. As a way of answering it, the following were developed: the Multidimensional Model of Gender-Conscious Urbanism, the My Walk Travel Log, the Immobility Log and the Neighbourhood Satisfaction Survey. These are the tools of the urban analysis methodology proposed in order to understand the experience of women in the above-mentioned territory, including quantitative and qualitative variables, making perception the central element of the analysis.
ПІДВИЩЕННЯ СТУПЕНЯ ГАЗОВИЛУЧЕННЯ РОДОВИЩ ПРИРОДНИХ ГАЗІВ В УМОВАХ ПРОЯВУ ВОДОНАПІРНОГО РЕЖИМУ З ВИКОРИСТАННЯМ ДІОКСИДУ ВУГЛЕЦЮ

Published: April 2022

Для вдосконалення існуючих технологій розробки родовищ в умовах прояву водонапірного режиму проведено додаткові дослідження з використанням основних інструментів гідродинамічного моделювання Eclipse та Petrel компанії Schlumberger. На основі результатів проведених досліджень встановлено, що при наявності значної неоднорідності продуктивних покладів необхідно забезпечити більшу щільність сітки нагнітальних свердловин для ефективного блокування просування пластової води порівняно з розробкою однорідних покладів за таких же умов. Такий результат досліджень пояснюється випереджаючим просуванням фронту пластової води та невуглеводневого газу по найбільш високопроникних пропластках газоконденсатного покладу. За результатами проведених досліджень визначено максимальне значення кількості нагнітальних свердловин для нагнітання діоксиду вуглецю в однорідний та неоднорідний поклади з метою зниження активності водонапірної системи та забезпечення стабільної експлуатації видобувних свердловин протягом тривалішого періоду розробки продуктивних покладів. Максимальне значення кількості нагнітальних свердловин на момент прориву діоксиду вуглецю до видобувних свердловин становить 6,41 (6) свердловин для однорідного покладу та 7,74 (8) свердловин для неоднорідного покладу. Прогнозний коефіцієнт вилучення газу для наведеного максимального значення кількості нагнітальних свердловин в однорідній моделі становить 65,05 % а в неоднорідній моделі – 55,56 %. При розробці на виснаження кінцеві коефіцієнти вилучення газу для однорідної та неоднорідної моделей становлять 51,72 % та 49,44 %, відповідно. Результати досліджень свідчать про технологічну ефективність впровадження технології нагнітання діоксиду вуглецю на межі початкового газоводяного контакту з метою регулювання надходження пластових вод в газонасичені горизонти та збільшення кінцевого коефіцієнту вилучення газу за таких умов.

Published: April 2022

BackgroundLeft bundle branch block (LBBB) is a common complication of the transcatheter aortic valve replacement (TAVR), and its impact on prognosis is controversial.MethodsA comprehensive electronic search was conducted in databases (PubMed, Embase, Cochrane Library, and The Web of Science), from the date of database establishment till March 2021, to screen for studies on new-onset LBBB after TAVR. We next performed a meta-analysis to evaluate the effect of new-onset LBBB after TAVR on patient prognosis, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.ResultsA total of 17 studies, including 9205 patients, were eligible for our analysis. Patients with new-onset LBBB had elevated all-cause mortality risk verses patients without new-onset LBBB, during all follow ups. The relevant data are as follows: 30-day (RR:1.71; 95%CI:1.27–2.29; P &lt; 0.001), 1-year (RR:1.31; 95%CI:1.12–1.52; P &lt; 0.001), and 2-year (RR:1.31; 95%CI:1.09–1.56; P = 0.003) follow ups. Likewise, new-onset LBBB patients also experienced increased cardiovascular mortality, compared to non-new-onset LBBB patients, but only in the 1-year follow up (RR:1.49; 95%CI:1.23–1.82; P &lt; 0.001). Hospitalization for heart failure was dramatically elevated in patients with new-onset LBBB verses non-new-onset LBBB, in all follow ups. The relevant data are as follows: 30-day (RR:1.56; 95%CI:1.13–2.12; P = 0.007), 1-year (RR:1.35; 95%CI:1.08–1.68; P = 0.007), and 2-year (RR:1.49; 95%CI:1.21–1.84; P &lt; 0.001). Similarly, new-onset LBBB patients had higher PPI risk than non-new-onset LBBB patients, in all follow ups. The relevant data are as follows: 30-day (RR:3.05; 95%CI:1.49–6.22; P = 0.002), 1-year (RR:2.15; 95%CI:1.52–3.03; P &lt; 0.001), and 2-year (RR:2.52; 95%CI:1.68–3.78; P &lt; 0.001).ConclusionPatients with new-onset LBBB have worse prognosis after TAVR than those without new-onset LBBB. Recognition of the adverse effects of post-TAVR new-onset LBBB can lead to the development of new strategies that enhance clinical outcomes.Systematic Trial Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=197224, identifier: 19722.

Authors: Zhang Xiaofeng , Liang Hong , Feng Jianchao , Tan Heping 
Published: April 2022

Obtaining high precision temperature data is crucial in spaceflight applications, considering the growing demand for high precision temperature measurement and the limited onboard resources with a harsh thermal environment in the spacecraft. How to obtain the data, however, becomes an urgent problem. Kalman filtering method is one of the solutions to obtain high precision temperature data with such limited resources. In this paper, the authors demonstrate the principle of temperature measurement system, the application of Kalman filter in temperature measurement including the processing method of sensor self-heating effect, and establishes the state space of measurement error and system error. Through the test, it could be seen that Kalman filtering can improve the temperature measurement resolution to the order of 100 μK while effectively reducing the temperature measurement bias.
Modeling Soil Carbon Under Diverse Cropping Systems and Farming Management in Contrasting Climatic Regions in Europe

Published: April 2022

Sustainable agriculture has been identified as key to achieving the 2030 Agenda for the Sustainable Development Goals, which aims to end poverty and hunger and address climate change while maintaining natural resources. Soil organic carbon (SOC) sequestration is a key soil function for ecosystem services, and storing carbon (C) in soil by changing traditional management practices can represent an important step toward the development of more sustainable agricultural systems in Europe. Within the European project Diverfarming, the process-based ecosystem model ECOSSE was modified and evaluated in four long-term experiments (&gt;8 years) to assess the impact of crop diversification and agricultural management in SOC dynamics. ECOSSE was able to simulate SOC under dry conditions in Mediterranean regions in Spain and Italy. In the site of Murcia, Spain, the addition of manure and cover crop in the diversified systems produced an increase of SOC in 9 years, when compared with the conventional management (16% measured increase, 32% simulated increase). The effect of tillage management on SOC stock in dry soil, in Foggia, Italy and Huesca, Spain, was also modeled, and a positive impact on SOC was predicted when no tillage was practiced. Finally, ECOSSE was used to understand the impact of diversifications in Boreal regions, Finland, where different proportions of legumes and grass were considered in a 4-year crop rotation compared with conventional cereal rotations. Experiments and modeling showed that the loss of SOC in conventional cereal was compensated when grass was introduced in the rotations. A good agreement (NRMSE &lt;10%) and a nonsignificant bias were observed between model and experimental data for all sites. Mitigation scenarios considered in the modeling analysis for the test site Huesca showed that an integrated management of no tillage and manure is the best strategy to increase SOC, ∼51% over 20 years, compared with the baseline scenario (current farmers practice). This study demonstrated the ability of the modified version of ECOSSE to simulate SOC dynamics in diversified cropping systems, with various soil management practices and different climatic conditions.

Published: April 2022

Background: Musculocontractural Ehlers–Danlos syndrome (mcEDS) is a rare heritable connective tissue disease with various symptoms. The diagnosis of mcEDS is difficult because of the large overlap of clinical symptoms between different EDS subtypes.Methods: We performed karyotype analysis, gene copy number variation detection, whole-exome sequencing, and Sanger sequencing to reveal the underlying genetic etiology of a fetus with structural abnormalities in feet and kidneys.Results: A likely pathogenic mutation [NM_130468.3 c.958C&gt;T (p.Arg320*)] and an uncertain significance mutation [NM_130468.3 c.896A&gt;G (p.Tyr299Cys)] were identified in the carbohydrate sulfotransferase 14 (CHST14) gene by whole-exome sequencing and validated by Sanger sequencing.Conclusion: The two identified mutations appear highly likely to be the genetic causes of the fetal structural abnormalities.

Published: April 2022

BackgroundThe fractional amplitude of low-frequency fluctuation (fALFF) method has been underutilized in research on the pathogenesis and clinical manifestations of ocular hypertension (OH).PurposeThis study uses resting state functional magnetic resonance imaging (rs-fMRI) and fALFF to investigate the nature of spontaneous brain activity in OH patients and the relationship, if any, between changes in activity and clinical features.Materials and MethodsA total of 18 subjects (9 females and 9 males) with ocular hypertension (OH) and 18 healthy controls (HCs) matched for gender, age, and educational level were recruited to this study. All participants underwent an rs-fMRI scan, and spontaneous brain activity was assessed using the fALFF method. Receiver operating characteristic curves were plotted to investigate differences between OH and HC groups.ResultsThe fALFF values of OH patients were significantly higher in the left precuneus lobe (LP), compared with the same region in controls (P &lt; 0.05). Conversely, values in the left anterior cingulate lobe (LAC), were significantly lower (P &lt; 0.05) in OH than in controls. However, no significant association was found between the mean fALFF values and clinical characteristics in either brain area.ConclusionHigh spontaneous activity in two brain areas may reflect neuropathological mechanisms underpinning visual impairment in OH patients.
