Aim. To study of serum magnesium in women with a history of adverse pregnancy outcomes.Materials and Methods. 74 women of child-bearing age, subject to voluntary informed consent, participated in a prospective cohort study. The main group (n = 31) included non-pregnant women who had a history of unfavorable gestation outcomes: premature birth, spontaneous miscarriage, habitual miscarriage, undeveloped pregnancy. The comparison group (n = 43) consisted of non-pregnant women with a history of two or more urgent deliveries. In all women, in preparation for pregnancy, the content of serum magnesium was determined by colorimetric method with xylidine blue.Results. 77.6% of women with a burdened obstetric history of miscarriage (the main group) had various menstrual cycle disorders (FIGO, 2018). When analyzing the levels of magnesium in the blood serum of the examined women, it turned out that the obtained indicators in women of both groups corresponded to the established reference range of normal values of serum magnesium levels. At the same time, in the women of the main group, the average magnesium content in the blood serum was significantly lower and was closer to the lower limit of the range of normal values, and in the comparison group – in the middle of the range of normal values: 0.719 (0.672-0.767) mmol/l and 0.844 (0.778-0.922) mmol/l, respectively, p<0.001.The optimal threshold value of the serum magnesium index in the study was 0.796 mmol/l with the sensitivity and specificity of the proposed prognostic model of 80.6% and 81.4%, respectively.Conclusion. Determination of the level of magnesium in the blood serum of women at the stage of pre-pregnancy counseling is of particular importance. Despite the fact that all the examined women had serum magnesium levels within the range of its normal values, significantly lower serum magnesium levels were found in women with adverse pregnancy outcomes in the anamnesis, which necessitates prescribing magnesium-containing medications to such patients at the stage of pregnancy planning. For the prevention of miscarriage within the framework of preconception preparation with serum magnesium values ≤0.796 mmol/l, the intake of organic magnesium salts is recommended.

Wiwitan Sebagai Pergelaran Budaya Dalam Tinjauan Ekofeminisme
Authors: Sathotho Surya Farid 
Published: January 2024

Penelitian ini melakukan analisis wiwitan di Desa Sumber, Kecamatan Dukun, Kabupaten Magelang, Jawa Tengah sebagai pergelaran budaya. Tradisi Wiwitan secara umum merupakan sebuah bentuk penghormatan kepada Dewi Sri yang merupakan dewi padi. Sejarah turunnya ajaran wiwitan dimulai dari cerita rakyat Dewi Sri yang datang ke Tanah Jawa saat mengalami paceklik. Mereka memohon kepada Tuhan untuk diberikan rezeki dan terbebas dari bencana yang saat itu melanda. Wiwitan merupakan bentuk upacara yang berupa selamatan atau kenduri dan dilaksanakan sebelum melakukan panen. Menarik untuk dilihat mengapa pada masa sekarang ritual ini tetap dilakukan oleh sebagian petani meski dengan cara yang sederhana. Pada ritual tersebut terdapat unsur-unsur pertunjukan. Metode penelitian kualitatif memiliki beberapa keunggulan, yaitu: penyesuaian metode kualitatif lebih mudah apabila berhadapan dengan kenyataan peneliti, menyajikan secara langsung hakikat hubungan antara peneliti dan responden, serta lebih peka dan dapat menyesuaikan diri dengan banyak penajaman pengaruh bersama dan terhadap pola- pola nilai yang dihadapi. Sebagai sebuah kegiatan yang mengandung unsur pertunjukan, maka kajian dari sudut pandang teater sangat memungkinkan. Ada keterkaitan antara teater dan ritual sehingga mengkaji sebuah ritual dengan pendekatan teater ataupun sebaliknya sangat memungkinkan dengan menggunakan pemahaman pergelaran budaya atau cultural performance. Sosok Dewi Sri sebagai dewi padi yang dipuja petani memperlihatkan konsep Kosmologi Jawa terhadap Perempuan. Adanya unsur laki-laki dan perempuan dalam bentuk-bentuk ritual memperlihatkan bahwa kajian ekofeminisme bisa dilakukan pada ritual. Konsep ekofeminisme membahas bagaimana menyetarakan antara perempuan dan bumi serta hubunganya dengan laki-laki dalam budaya patriarki. Kata kunci: wiwitan, pergelaran budaya, ritual, ekofeminisme

The phenomenon of the Z-Telegram in the coverage of events in Ukraine
Authors: Chirkin Dmitrii Yur'evich , Kolmakov Andrei Dmitrievich , Skupov Mikhail Vasil'evich 
Published: January 2024

The purpose of the study is to identify and describe the phenomenon of Z-Telegram channels against the background of the general state of the information field with the theme of a special military operation. The subject of the study is the image of a politician or authority formed by Z-channels. The authors focus on the concept of Z-channels, the features of their content, as well as the factors of the appearance of these channels. The key features of the Z-channels were the concentration on combat operations, the assessment of the politician through the prism of combat operations and criticism of the command and authorities. The differences between Z-channels and traditional media are studied in detail. The prospects for the formation of political communities based on Z-channels are considered. The article analyzes the reasons for the popularity of Z-channels and their role in covering a special military operation. The article examines the influence of the personality of the author of the channel on the attitude towards the key actors of the special military operation. Special attention is paid to the differences in the subject of the channels. The method used was the method of content analysis of the collected material, which includes posts in these most famous Z-channels during the winter of 2022-2023. The scientific novelty of the research lies in the study of the phenomenon of Z-channels in the Telegram as an alternative to traditional media, as well as the consideration of Z-channels as a prototype for the formation of a new type of political opposition to the current political system. The results of the study, presented as conclusions, showed that Z-channels can form a common agenda independently of each other, while having similar views. So, all channels broadcast a negative image to the official representatives of the Ministry of Defense of the Russian Federation, and at the same time broadcast a moderately positive image to Prigozhin. This allows us to conclude that for a number of reasons discussed in the study, Z-channels on the Telegram social network can form and broadcast their own agenda, including one that differs from the official one, and also have a very large audience.
Benefits and Challenges of Electric Propulsion for Commuter Aircraft
Authors: Kruger Michael , Uranga Alejandra 
Published: January 2024

This paper presents the Library for Unified Conceptual Aircraft Synthesis (LUCAS) sizing and optimization framework, which is largely based on Stanford’s Stanford University Aerospace Vehicle Environment (SUAVE). LUCAS is applied to a commuter mission carrying 19 passengers. Results show that energy usage benefits depend on mission range and electrical component technology and that reserve requirements play a significant role in the feasibility of electrified aircraft. It is found that storing more energy in batteries rather than fuel reduces the mission energy requirement at the expense of aircraft weight growth. All-electric aircraft could provide onboard energy savings of upward of 30% for a 180 km mission, but this would only become feasible if battery specific energy reached the high value of [Formula: see text]. Range could be increased to 550 km if part of the reserve mission requirements is relaxed. Under more realistic technology assumptions, a hybrid design storing energy in fuel and batteries could fly commuter missions with energy savings of 6%. A beneficial use case of hybrid configurations is a mode of operation where the aircraft uses only batteries during the main mission and fuel to store all the reserve energy. If reserves are not required for a particular flight, energy savings are still maximized, while the availability of fuel ensures certification requirements are met with fewer penalties.
Rapid-Throughput Analysis of Human Milk Oligosaccharides from Filipino Breastmilk

Published: January 2024

Human milk oligosaccharides (HMOs), although considered indigestible to the infant, are the third most abundant solid component of breastmilk. They serve many health-related functions benefitting the infant, such as nourishment of gut bacteria, inhibition of pathogenic infection, and aiding in brain development. In this study, a rapid-throughput analytical method is validated for Filipino breastmilk HMOs. The method entails lipid extraction by centrifugation, protein precipitation using ethanol, alditol sugar reduction using sodium borohydride, and solid phase extraction purification using porous graphitized carbon, all in a 96-well plate format. Nano-HPLC Chip/TOF-MS, coupled with the use of Agilent MassHunter programs for filtering datasets using an in-house library, is then used to analyze purified HMOs. The results evidently show that the rapid-throughput method minimizes sample loss, ensures reproducible MS signals, and considerably shortens sample handling time. Furthermore, the method significantly reduced analysis time 5-fold and eliminated the individual sample preparation, which enabled simultaneous analysis of 386 samples (four 96-well plates) in a single run. Thus, the rapid-throughput analysis is highly efficient and effective for the profiling and structural determination of Filipino breastmilk HMOs even in large sample population sets.

RUSIA–UCRANIA: ¿ES UNA GUERRA TRIBUTARIA?
Authors: Sanz Jofré Jorge , Martínez Toro Javiera , Ibáñez Guzmán Javier 
Published: January 2024

La guerra Rusia–Ucrania comenzó como parte del desarrollo de una guerra híbrida llevada adelante por Rusia a través de la ocupación de Crimea y el Donbás en 2014, y que, al no poder conquistar los objetivos políticos planteados, como la instalación en Ucrania de un gobernante proruso, rompe el derecho internacional e invade militarmente la soberanía ucraniana.
La reacción de Occidente (EE. UU.–U.E.), no estuvo en la apreciación rusa y durante un año se ha visto enfrentada a una guerra de resistencia que no puede romper. En el tiempo, la invasión rusa ha sido enfrentada y detenida, Rusia ha sido sancionada por el mundo occidental y paralelamente se aprecia que su principal aliado, China, se ve indirectamente afectado al no poder avanzar con su proyecto de la Ruta de la Seda hacia Europa.
Estados Unidos busca el desgaste de Rusia a través de las sanciones y la resistencia militar ucraniana con equipamiento occidental, la sobreproducción de la industria militar rusa afectada por la falta de materias primas y, probablemente iluminado por un objetivo mayor ubicado en el Indo–Pacífico referido a mantener la condición de primera potencia mundial; por tanto, ¿es la guerra Rusia-Ucrania una guerra tributaria de un conflicto mayor en el Indo–Pacífico?
