Purpose. To investigate the influence of the magnetic field on the formation of structures in magnetic media of various dispersities. Methods. Experiments to study the dynamics of magnetic inclusions were carried out on a self-made installation in flat transparent cells by microscopy. The magnetic field was created by an electromagnet FL-1 connected to a power source. Magnetite particles of various sizes, as well as metal balls with a diameter of 0.5 mm, were studied as a magnetic medium. Video recording was performed using a MICMED WiFi 2000X 5.0 microscope. Results. The dynamics of magnetic inclusions in a viscous liquid medium under the influence of a magnetic field, as well as under conditions of mechanical shear effects, have been studied. The influence of the magnetic field strength on the growth rate of chain structures, as well as on the angle of deflection under shear action, has been studied. A theoretical interpretation of the observed phenomena is proposed. Conclusion. During the experiment, it was found that under the influence of a magnetic field, magnetic inclusions form chain structures. Their size, growth rate and dynamics depend on the physical parameters of the system and the external magnetic field. An intensive increase in the formation of chains of magnetic inclusions was detected at low and medium values of the magnetic field strength. An experimental dependence of the angle of deviation of chain structures from the equilibrium position on the magnetic field strength is obtained, which correlates with known theoretical data, on the basis of which a computational model is proposed. The results of the study can be used to visualize numerical calculations of the dynamics of dispersed systems under external influences.

Published: July 2024

Background. Venous thrombosis and embolism are one of the main and most threatening complications in emergency abdominal surgery in the conditions of global pandemic caused by the SARS-CoV-2, which is constantly worsening the morbidity and mortality rates. Despite the accumulation of sufficient knowledge on the problem of venous thromboembolism in general, understanding the unique prothrombotic pathophysiology of the virus and its potentiation of the coagulation system in patients with COVID-19 remains at a suboptimal level. The purpose of the study is to assess the extent of venous thrombosis in patients undergoing emergency surgery for abdominal pathology with concomitant coronavirus disease and to determine the main measures to improve the effectiveness of prevention and treatment. Materials and methods. The results of the treatment of 3,476 patients in the Surgical center 1 of the CNPE of the Lviv Territorial Medical Union “Multidisciplinary Clinical Hospital of Intensive Treatment Methods and Emergency Medical Care” from April 2021 to March 2022 were analyzed, 89.3 % of them were hospitalized urgently. One hundred and fifty-nine (4.6 %) patients died, mainly from purulent-septic complications, multi-organ (primarily severe respiratory) failure and venous thrombosis and embolism. Results. Non-specific prevention of venous thrombosis and embolism was carried out in all patients. It consisted in elastic compression of the legs before transporting the patient to the operating room and early ambulation after surgery. Adequate analgesia and assistance from medical staff were considered an important component of motor activity recovery. Specific prevention of venous thrombosis was carried out by subcutaneous injection of low-molecular-weight heparins once or twice a day. With the beginning of the pandemic and a sharp rise of thromboembolic complications, a longer prophylaxis with increased dose and frequency of anticoagulant administration began to be used in clinical practice. Conclusions. Unresolved issues that stood in the way of optimizing the prevention of venous thrombosis and embolism in the clinic are the new challenges associated with the COVID-19 pandemic, insufficient alertness of doctors to the problem of thromboembolic complications, difficulties in objective assessment of the risk of deep vein thrombosis in the presence of many factors, absence of scales for evaluating the risk of venous thrombosis adapted to today’s conditions.

Published: July 2024

Penelitian ini dilatarbelakangi oleh terbatasnya hasil riset yang menunjukkan literasi emosi peserta didik. Oleh karena itu, dalam penelitian ini tujuannya difokuskan untuk menggambarkan bagaimana literasi emosi peserta didik terkait aspek mengetahui perasaan diri. Penelitian ini menggunakan pendekatan kualitatif dengan metode classroom ethnography. Partisipan penelitian ini adalah peserta didik dan guru di salah satu SD. Teknik pengumpulan data dilakukan melalui observasi, wawancara dan dokumentasi. Analisis data penelitian ini didasarkan pada teori literasi emosi oleh Steiner, terdapat tiga tahapan, yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa peserta didik mengetahui emosi tertentu sesuai dengan yang dirasakannya, tetapi tidak mengetahui bagaimana mengungkapkannya supaya tidak berdampak negatif terhadap kualitas hidupnya dan orang lain; selain itu sejumlah besar peserta didik sudah mengetahui alasan emosi yang merasa rasakan, tetapi beberapa peserta didik cenderung mengekspresikan emosi tersebut secara spontan dengan cara negatif melalui ekspresi wajah dan gestur tubuh seperti menunjukkan tatapan sinis, dahi mengerut disertai wajah memerah, nafas menderu, menghindar dan menendang meja. Dapat disimpulkan bahwa literasi emosi peserta didik utamanya pada aspek mengetahui perasaan diri masih belum memadai.Â Dengan demikian, edukasi literasi emosi bagi peserta didik SD dipandang penting untuk mulai diterapkan sedini mungkin melalui lembaga pendidikan formal utamanya dalam KBM.

Authors: Hogan Chris E. , Myers Linda A. , Wilkins Michael S. 
Published: July 2024

ABSTRACT
The introduction is the most important part of an academic paper. Beyond summarizing a paper’s findings, it is also the author’s first and best opportunity to “sell” the paper to readers with varying levels of interest. Our purpose in this commentary is to provide a framework for writing high-quality introductions. We present a specific structure and also provide guidance regarding content—both what to include and what not to include. Finally, we offer recommendations for revising the introduction as a paper evolves and present additional suggestions for writing in general. Although our primary intended audience is Ph.D. students and early assistant professors, experienced faculty members may benefit as well.

Published: July 2024

Numbers and Sets are mathematical subject matter that can be learned using context in life. One of the contexts that can be used is gamelan artifacts. Gamelan contains the values of local wisdom that have become part of the identity of the Indonesian nation. Ethnomathematics sets and numbers in gamelan must be explored as contexts in related mathematical learning. The study aims to explore ethnomathematics related to the sociocultural context of Gamelan, offering an alternative approach to mathematical learning on sets and numbers. Employing an interpretive ethnographic approach based on Alangui's framework, the study unfolds across two art studios and three schools in Indonesia, engaging karawitan art culturalists and junior high school mathematics teachers as key informants. Through observation, documentation, field notes, and interviews, our findings reveal that gamelan artifacts can enrich the teaching of sets and numbers with their various types, shapes, and sizes. Hence, the results offer a transformative perspective for teachers, preservice teachers, and mathematics educators to integrate gamelan artifacts into mathematics lessons.

Published: July 2024

Defamation on social media, especially via the Facebook platform, has become an increasingly disturbing issue in society. This research aims to understand theeffectiveness of criminal law enforcement under the Information and Electronic Transactions Law (UU ITE) in cases of defamation on Facebook. Mixedqualitative and quantitative research methods were used, including literature studies, interviews, social media content analysis, surveys, and statistical analysis. The research results show that the phenomenon of defamation on Facebook faces challenges in law enforcement, including difficulties in identifying perpetrators, the length of the legal process, and public distrust of the effectiveness of law enforcement. Recommendations are given to increase cooperation between the police, legal institutions and social media platforms, as well as to increase public education about the dangers of defamation. In conclusion, criminallaw enforcement against defamation on Facebook requires a holistic approach involving various parties and ongoing efforts to create a safer and more ethicaldigital environment. Even though the Information and Electronic Transactions Law (UU ITE) provides a clear legal basis, law enforcement still faces variouschallenges, including difficulties in identifying perpetrators, the length of the legal process, and low public trust in the effectiveness of law enforcement. The proposed recommendations include increasing cooperation between the police, legal institutions and social media platforms, as well as intensifying publiceducation about the dangers of defamation. These steps are important for creating a safer and more ethical digital environment for all users. By understanding the challenges faced and through joint efforts across sectors, it is hoped that criminal law enforcement against defamation on Facebook and social media can beimproved, so that individual human rights can be better protected and the integrity of the digital environment can be maintained.

Abstract

OBJECTIVE
To develop an innovative process for stereotactic brain biopsies in dogs and cats that would provide a definitive diagnosis and optimize the management of patients with brain lesions.

ANIMALS
4 dogs and 1 cat diagnosed with 1 or more brain lesion(s) underwent brain biopsies between March 24, 2023, and October 25, 2023.

METHODS
Based on trajectories selected on images of MRI and CT scan performed on each patient, a computerized software program was used to design a 3-D–printed patient-specific device with maxillary dental impression located on a baseplate to secure the patient's head and with insertion ports for the biopsy instrumentations located on a C-arm. As proof of concept, the device was successfully used in 2 cadavers before being used on clinical patients. All biopsy samples were submitted for histopathological examination.

RESULTS
Histological diagnosis was obtained in 80% (4/5) of the cases (choroid plexus tumor, astrocytoma, meningioma, and chronic meningoencephalitis of unknown origin). In 1 patient, the results of biopsy were nondiagnostic; postmortem diagnosis was consistent with a low-grade oligodendroglioma. All the patients were discharged within 24 hours after the procedure without complications. This novel stereotactic system allows the surgeon to perform safe, easy-to-use, inexpensive, and minimally invasive precise brain biopsies in dogs and cats, without complications.

CLINICAL RELEVANCE
This unique technique could be applied to any size and type of skull and for any type of brain lesions and would provide diagnostic information that would be valuable for future treatment planning and prognosis.

Published: July 2024

European Shock Tube for High-Enthalpy Research (ESTHER) is a new state-of-the-art combustion-driven shock tube developed for supporting future ESA planetary exploration missions. Its high-pressure combustion driver sports a unique innovative design where a mixture of [Formula: see text] or [Formula: see text] gases, filled to pressures up to 100 bar, is ignited by a high-power Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. The qualification of this facility driver has allowed for the detailed study of laser-ignited combustion processes at high initial pressures (in the 5–100 bar range), over a series of 100 shots carried out for different configurations and gas mixtures. The influence of the oxygen-to-hydrogen ratio, filling pressure, inert gas dilution, and ignition mode have been studied and are presented in this work. The effects of nitrogen vs helium dilution are also discussed. Filling pressure and helium/nitrogen dilutions have the strongest influence in peak pressure, acoustic oscillation, and combustion velocity. The first two increase, whereas the latter strongly decreases with the filling pressure. Nitrogen diluted shots have drastically lower compression ratios and flame velocity when compared to the helium ones. Acoustic perturbations/instabilities are also found to be stronger. This test campaign allowed the definition of a large range of stable and reproducible firing conditions in deflagration mode, yielding post-combustion pressures up to 660 bar.
