Instrumentale Melodieanfänge und ihr Verhältnis zur Form am Beispiel historischer und gegenwärtiger ungarischer Tanzmelodien
Authors: Tari Lujza 
Published: September 2024

AbstractThe aim of this study is to analyze the beginning of different dance tunes in connection with variously performed dance tunes. The purpose of this paper is also to draw attention to the need for micro-analysis, which has been neglected for a long time in instrumental folk music research, in order to better understand instrumental musical melody creation. The selected musical examples come from different (partly historical) eras and different geographical areas of Western Transdanubian and Transylvanian Hungarian folk music collections. Typical starting elements (fifth-forth changes, direction of moving of scales, etc.) are related to dance music with different names. The analysis ignores the evolution of tempo and variation throughout the piece, as well as the ensemble's “Primas” ornamentation, timbre, harmonies and unique solutions of the accompaniment. At the same time, the author paid attention to the form and structure of the entire piece in addition to the beginnings of the melody. The study was written in honor of the 100th birthday of Walter Deutsch, the creator of modern Austrian ethnomusicology.

Empyema in the lungs can cause pulmonary fibrosis which can cause restrictions in the movement of the lung parenchyma. Epigallocatechin-3-gallate (EGCG) is the most active polyphenolic compound in gambier leaves (Uncaria gambir Roxb), which is known to inhibit the occurrence of pulmonary fibrosis due to empyema. This literature review discusses the role of EGCG in inhibiting the development of pleural fibrosis in empyema patients.
EGCG prevents bleomycin-induced increase in ROS formation, reverses the decrease in antioxidant status, and increases Nrf2 activity. EGCG also reduces inflammatory markers such as NF-κB, TNFα, IL-1β, and MPO activity levels and reduces histological signs of inflammation and lung injury. EGCG lowers hydroxyproline and glycoconjugates, products of collagen metabolism, reduces matrix-degrading lysosomal hydrolases and improves ultrastructural changes in the lungs. EGCG also exerts antifibrotic activity by suppressing the expression of TGF-β and the SCUBE3 gene.
The EGCG compound inhibits the development of pulmonary fibrosis in empyema through antioxidant and antifibrotic activities by suppressing SUBE3 and TGF-β gene expression.

Empiema pada paru dapat menyebabkan terjadinya fibrosis paru yang dapat menyebabkan restriksi pada pergerakan parenkim paru. Epigallocatechin-3-gallate (EGCG) adalah senyawa polifenol paling aktif dalam daun gambir (Uncaria gambir Roxb) yang diketahui dapat menghambat terjadinya fibrosis paru akibat empiema. Tinjauan pustaka ini membahas mengenai peran EGCG dalam menghambat perkembangan fibrosis pleura pada pasien empiema.
EGCG mencegah peningkatan pembentukan ROS yang diinduksi bleomisin, mengembalikan penurunan status antioksidan, dan meningkatkan aktivitas Nrf2. EGCG juga mengurangi penanda peradangan seperti tingkat aktivitas NF-κB, TNFα, IL-1β dan MPO serta mengurangi tanda-tanda histologis peradangan dan cedera paru-paru. EGCG menurunkan kadar hidroksiprolin dan glikokonjugat, produk metabolisme kolagen, mengurangi hidrolase lisosom yang menurunkan matriks, dan memperbaiki perubahan ultrastruktur di paru-paru. EGCG juga melakukan aktivitas antifibrotik dengan menekan ekspresi TGF-β dan gen SCUBE3.
Senyawa EGCG mampu menghambat perkembangan fibrosis paru pada empiema melalui aktivitas antioksidan dan antifibrotik dengan menekan ekspresi gen SUBE3 dan TGF-β.

Authors: Yuliantini Ni Nyoman , Putri Dian Kusumastuti Anggraeni , Suputra Gede 
Published: September 2024

Introduction: Subdural hematoma (SDH) commonly occurs due to severe head trauma but can also occur spontaneously. Spontaneous SDH in young adults is a rare case because it generally occurs in old age due to brain atrophy, which increases the risk of bridging vein rupture.
Case report: A 23-year-old man was taken to the emergency room with complaints of decreased consciousness. He had a history of headaches in the last 6 days, which did not improve with analgetic. There is no history of previous trauma. Physical examination found GCS E2V2M4, anisocoric pupils, and no lateralization of muscle strength. A non-contrast head CT shows SDH in the right fronto-temporo-parietal region, which caused the subfalcine herniation to the left as far as ±1.3 cm. He underwent a hematoma evacuation with cito decompressive craniectomy and external ventricular drainage. His condition improved after surgery.
Conclusion: Spontaneous SDH in young adults is quite a rare case and the diagnosis is often delayed because the initial symptoms are not typical. Based on several case reports, spontaneous SDH in young adults can occur due to coagulopathy, arteriovenous malformations, aneurysms, intracranial hypotension, arachnoid cysts, or drug abuse such as cocaine and amphetamines. The etiology in this case is still unclear, so further investigation is necessary to reduce the risk of recurrent bleeding.

Pendahuluan: Perdarahan subdural biasa terjadi akibat trauma kepala yang berat, namun dapat juga terjadi secara spontan. Perdarahan subdural spontan pada dewasa muda merupakan kasus yang jarang, karena umumnya terjadi pada usia tua akibat atrofi otak yang meningkatkan risiko rupturnya bridging vein.
Laporan Kasus: Laki-laki usia 23 tahun dibawa ke IGD rumah sakit dengan keluhan penurunan kesadaran. Pasien riwayat mengeluhkan nyeri kepala sejak 6 hari sebelumnya yang tidak membaik dengan antinyeri. Pasien tidak ada riwayat trauma sebelumnya. Pemeriksaan fisik didapatkan GCS E2V2M4, pupil anisokor, dan kesan lateralisasi tenaga tidak ditemukan. CT scan kepala tanpa kontras didapatkan perdarahan subdural pada regio fronto-temporo-parietal kanan yang menyebabkan subfalcine herniasi ke kiri sejauh ±1,3 cm. Pasien dilakukan evakuasi hematoma dengan dekompresi kraniektomi dan pemasangan external ventricular drainage cito. Kondisi pasien membaik pasca tindakan pembedahan.
Kesimpulan: SDH spontan pada dewasa muda merupakan kasus yang cukup jarang, penegakkan diagnosis seringkali terlambat karena gejala yang tidak khas. Berdasarkan beberapa laporan kasus, SDH spontan pada dewasa muda bisa terjadi akibat koagulopati, malformasi arterivena, aneurisma, hipotensi intrakranial, kista arachnoid, atau penyalahgunaan obat-obatan seperti kokain dan amfetamin. Etiologi pada kasus ini masih belum jelas, sehingga perlu dilakukan penelusuran lebih lanjut untuk mengurangi risiko perdarahan berulang.

Introduction: COVID-19 is a condition carried upon by those infected with the SARS-COV-2 coronavirus. Hypercoagulability is one of the many signs of COVID-19. Although the etiology leading to this hypercoagulable state remains unclear, some studies have suggested that it may be linked to alterations in prothrombic factors and the disease's cytokine storm. One of the uncommon side effects brought on by a sudden drop in arterial limb perfusion is acute limb ischemia (ALI).
Case description: A 64-year-old woman confirmed COVID-19 patient who has acute limb ischemia on the right lower extremities and is in serious condition. The patient had an above-knee amputation in addition to a thrombectomy.
Conclusion: Acute limb ischemia is a threatened life condition that the presence of COVID-19 can aggravate. Early diagnosis and treatment of this therapy are necessary for a good prognosis.

In this study, using the method of probabilistic deterministic planning (PDP), the optimum design parameters of a standard polyethylene tank used worldwide for transporting liquid mineral fertilizers (LMF) were determined.
By the finite element method, the effect of the density of liquid mineral fertilizer, tank wall thickness and four motion modes (braking, acceleration, jump and landing) on the strength of standard polyethylene tanks was studied. According to the results of the study, the five most informative areas in the tank design were identified, for which the values of maximum stresses (σmax) were obtained: filler neck, pockets, walls, tap-in points and wall transition to the tank roof. As the LMF density increases, σmax in the tank increases linearly. Increasing the tank wall thickness by 1.5 times reduces the maximum stresses by 30 to 50 %. It was found that motion mode has a significant effect on the stress-strain state of a standard tank. The “heaviest” mode for a standard tank is “braking”. The “acceleration” motion mode causes σmax of no more than 60 % of the “braking” mode values. The “lightest” mode is “landing”, in which σmax is no more than 28 % relative to “braking”. Based on the PDP method, equations were derived for calculating maximum stresses depending on LMF density, wall thickness and motion mode of the tank. Nomograms were built that make it possible to quickly determine the wall thickness of a standard tank without calculations, depending on external factors. The results of the study can be used in practice when designing safe and durable tanks for transporting liquid mineral fertilizers.

The object of research is an element of equipment in a vibrating screen, which is an active working body in the form of a plate.
The key element in the system of the flush purification unit is the vibrating screen. The basic design of the sieve does not allow the flush solution to be distributed evenly over the entire working surface. The concentration of drilling fluid in the central part of the equipment leads to premature abrasive wear and failure of the working element. Therefore, the structure of the vibrating screen needs to be improved in order to extend its service life. This task has been solved through the introduction of an active element to the structure for the redistribution of the solution through additional transverse vibrations.
The use of such an active element is an important step for improving the quality and efficiency of the purification system, which could optimize production processes and reduce costs in industry.
Taking into account transverse vibrations and calculating frequency parameters could help improve the design and use the vibrating screen more productively.
An analysis of the frequencies of oscillations of the active element-plate for cleaning the flush liquid with a vibrating screen was performed and a comparison of the analytically obtained results with the simulation data using the finite element method in the COMSOL Multiphysics software was carried out. The results are the basis for designing vibrating screens, conducting experimental and industrial research, and testing the screens. Computer studies have confirmed the possibility of using the improved design of the vibrating screen. By comparing the results of the calculation and computer simulation, the error was determined to be within 5 %.
The identified patterns could make it possible to select the plate oscillation frequencies depending on the known initial parameters, which would be useful for solving similar tasks.

The object of this study was the technology of precision agriculture and remote monitoring of weather conditions. The task to evaluate the effectiveness of using precision farming and precision irrigation technologies in the activities of agricultural enterprises under different conditions, in particular, different climatic and weather conditions, has been considered. To solve the task, a hardware-software system for smart irrigation and remote monitoring of weather conditions in the activities of agricultural enterprises during the cultivation of agricultural crops was designed and described. Results of the system's performance were analyzed in the activities of the Ukrainian agricultural company, which grew potatoes of various varieties in the Kyiv oblast (Ukraine) from 2021 to 2023. The results show that the average yield of potatoes of different varieties without irrigation for three years of observation was 29.74 t/ha, with irrigation – 48.99 t/ha, and with smart irrigation – 55.26 t/ha. At the same time, in the latter case, water, human, and financial resources were saved. The increase in yield with smart irrigation compared to yield with conventional irrigation over the three years of observation was on average 12.8 %. According to the results of the implementation of the hardware-software system for smart irrigation and remote monitoring of weather conditions in Ukraine, the effect of the possible implementation of this system by agricultural companies in the Republic of Kazakhstan was analyzed. The forecast of the average yield of potatoes for the period from 2024 to 2026 was built based on the model of linear weighted moving average, taking into account corrections in the case of using smart irrigation. Data on potato yield from 1990 to 2023 were chosen as the basis. The use of smart irrigation according to the described technology could increase the yield of potatoes of various varieties on average from 31.71 t/ha to 35.78 t/ha in comparison with the forecast values of yield without irrigation at the level of 19.25 t/ha. This confirms the need to apply the transfer of precision farming technologies to increase the yield of agricultural crops, in particular potatoes, and the productivity of agricultural companies

The object of this study is a new design of an overhead microstrip antenna, including Epsilon Negative (ENG) metamaterials and L-shaped parasitic overlays aimed at achieving dual-band operation and improving the performance of modern wireless communication systems. The research is aimed at solving the problem of limited bandwidth and dual-band functionality in conventional antenna designs.
This study solves the problem of limited bandwidth and dual-band functionality in conventional microstrip patch antenna designs, which are crucial for modern wireless communication systems. The inclusion of L-shaped parasitic overlays effectively expands the bandwidth in each frequency range.
The results indicate significant improvements: at the upper resonant frequency, a 10 dB return loss bandwidth of 27.84 % (2.88–3.81 GHz) and a 3 dB axial ratio bandwidth of 5.05 % (2.90–3.05 GHz) are achieved, while at the lower resonant frequency, a return loss bandwidth is 10 dB, which is 6.11 % (2.22–2.36 GHz). These improvements indicate a significant increase in antenna performance compared to conventional designs, which is confirmed by comparing the simulation results with the measurement results.
Distinctive features contributing to these results include the use of ENG metamaterials, which improve electromagnetic properties and signal propagation; vertical transitions, which provide efficient dual-band operation; and L-shaped parasitic overlays, which significantly expand bandwidth. These characteristics combine to eliminate the limitations of traditional designs, which makes the proposed antenna suitable for use in a wide frequency range in modern wireless communication systems.

Reducing fruit losses is one of the most important strategies for improving diets and strengthening food systems. Therefore, improving modern technologies for storing sweet cherries, assessing the potential of the necessary capacities and technologies for fruit storage to reduce post-harvest losses and extend the shelf life of fruits remains relevant. Improvement of pre-cooling methods optimize the shelf life of fresh fruit and contributes to the growth of demand for fruit by consumers in the European market. The object of the study is the technology of pretreatment of sweet cherry fruits using an organic composition. The fruits of the model variety Valerii Chkalov were used as experimental material.
The minimum natural losses from microbiological diseases and physiological disorders were recorded on the 40th day of sweet cherry fruit storage. Fruit weight losses during storage of sweet cherries of the Valerii Chkalov variety were minimal when hydro cooling was applied in combination with a protective organic composition of lactic and acetic acid (1.75 %:2.00 %). The optimum concentration of lactic and acetic acids (2.00 %:1.75 %) was determined, which ensures minimal daily fruit losses (0.068 %) under the influence of hydro-cooling during storage of sweet cherries. The analysis of the regression model reveled the optimal value of the average level of daily losses during storage of sweet cherry fruit of Valerii Chkalov variety – 0.0642 % at concentrations of lactic and acetic acid 2.161 % to 1.705 %, respectively. The tendency to minimize sweet cherry fruit losses during storage under the influence of hydrocooling and the optimal concentration of organic acids in the protective composition was identified. The results could be used to improve pre-cooling methods in the food industry to preserve the quality of fruit raw materials in a waste-free fruit supply chain for all relevant stakeholders
