The mechanical properties of the dispersion-filled composites based on polypropylene (PP) and ground rubber scrap are studied in the temperature range from 40 to 120 °C. The content of the rubber particles is varied from 40 to 80 wt %. The peculiarities of the realization of a brittle-to-ductile or ductile-to-ductile transition in the composites are determined. The change in the deformation behavior occurs through the intermediate tension of the composite with the formation of several delocalized necks in the range of the filler concentrations. The negative effect of large particles during macrouniform tension of rubber plastics is shown for the first time. Their presence in the composite composition facilitates its fracture while the matrix polymer is underloaded (the effect of a single defect).
Predicting Bird Diversity with Lidar-derived Vegetation Structure in an African Savanna
Authors: Boucher Peter , Davies Andrew
Published: May 2023

Vegetation structural complexity and the diversity of animal communities are closely linked in vegetated ecosystems. These structure-diversity relationships have the potential to be used to predict biodiversity at large spatial scales using remote sensing data. However, structure-diversity relationships may not be generalizable across different ecosystems or even across ecotypes within a single ecosystem. To understand how structure-diversity relationships vary within the tree-grass mosaic of a savanna environment, we evaluated how bird diversity relates to vegetation structure at multiple scales and across environmental gradients in an East African savanna- the Selenkay Conservancy in southern Kenya. We obtained detailed characterizations of vegetation structure using Light Detection and Ranging (lidar) from Unoccupied Aerial Vehicle (UAV) surveys, and related vegetation structure metrics to bird diversity metrics (Shannon diversity and species richness) collected at 50 sites spread inside and outside of the Selenkay Conservancy. We compared structure-diversity relationships across environmental gradients, including soil type (red and black soils) and protected status (inside and outside the conservancy). We also compared structure-diversity models at multiple scales, testing how relationships changed with scale. We found significant structure-diversity relationships with improved performed at larger spatial scales (≥ 50 m radius or 0.79 ha circular plots). Models of Shannon diversity performed better than those of species richness. While most structure-diversity relationships only applied to specific soil types, certain models showed the potential to be generalized across soil types, explaining ~55-59% of the variance. We found that strong relationships exist between vegetation structure and bird diversity in savannas. While most structure-diversity relationships were only applicable to specific soil types, several vegetation metrics were able to track bird diversity across the entire landscape, performing well in both red and black soil sites. These results demonstrate the potential to use airborne remote sensing to monitor biodiversity across savanna environments.
Impact of Selected Macroeconomic Variables in Economic Growth: Empirical Study in the Philippines
Authors: Montances John Robert , Verano Andrei Angelo
Published: May 2023

This study investigates the relationship between foreign direct investment (FDI), household final consumption expenditure (HFCE), gross national income per capita (GNI), and the GDP growth rate in the Philippines. This study uses OLS estimation with annual time series data spanning 1981 to 2021 to assess the impact of these variables on the nation's economic progress. The Philippines' economy has developed significantly in recent years. Because the GDP growth rate is an important indicator of economic progress, policymakers must understand the factors that contribute to it in order to sustain economic growth. The study's findings offer important insights into the drivers of economic progress in the Philippines. Understanding the impact of FDI, HFCE, and GNI per capita on GDP growth rate enables policymakers to make informed decisions that encourage sustainable economic growth and increase the well-being of the entire population.

Compressive Strength of Concrete Containing Recycled Glass Powder
Authors: Nugraha Bimantara Putra , Sudjatmiko Eddy Triyanto , Bali Ika
Published: May 2023

Glass bottle waste takes a million years to decompose. Recycling is the best option to solve this problem. One
alternative is to use recycled glass in the form of powder as a material for making concrete. This study proposes the
use of recycled glass powder as a concrete material to partially substitute fine aggregate. This study aims to
determine the effect of glass powder as a partial substitute for fine aggregate on the compressive strength of concrete.
Partial substitution of fine aggregate was selected with a percentage of 5%, 10%, and 15%. Standard cylindrical
specimens aged 28 days used in compressive strength testing in this study. Then, the test results of concrete
containing recycled glass powder compared to ordinary concrete. The test results show that the compressive strength
of concrete containing 15% recycled glass powder gives an average compressive strength of 35.57 MPa which is
slightly higher than the compressive strength of normal concrete of 35.10 MPa. This study found that the use of glass
powder as a substitute for fine aggregate can be used as a substitute for normal concrete in terms of compressive
strength and reduce glass waste.

TO THE ISSUE OF MODERNIZATION OF PASSENGER CAR BODIES
Authors: Martynov I. , Kalabukhin Yu. , Trufanova A. , Martynov S. , Ostapenko I.
Published: May 2023

Passenger cars owned by JSC "Ukrzaliznytsia" have practically exhausted their resource. Improving the efficiency of railways requires the use of new innovative technical solutions.
The article analyzes the technical condition of the bodies of passenger cars that have worked out their resource. A total of 540 wagons of different years of construction were inspected.
In the course of the analysis, the results of inspections of the metal structures of cars were divided into five conditional groups depending on the service life. At the same time, the nominal values of the thicknesses of the structural elements of the car and the actual values were compared.
The authors determined the intensity of the increase in wear of various elements of the body. It has been established that the lower trim, the roof slope and the lower part of the side wall have the greatest wear.
It is proposed to use aluminum alloys for the modernization of passenger car bodies. The advantage of such a technical solution is an increase in the corrosion resistance of the body. This significantly increases the durability of the wagons and reduces the tare weight of the car.
The reduction of tare allows to reduce the specific resistance to train movement, reduce fuel and electricity costs for train traction, and the operating costs of railway transport for energy consumption.
To reduce operating costs using the basic provisions of the locomotive traction theory, calculations were made to determine the energy consumption for the movement of a passenger train according to the profile conditions of the real section of the regional branch of the Southern Railway by diesel and electric locomotive traction with the base variant and the variant of passenger cars with reduced tare weight) in composition of the train. In the calculations, it was considered that for the movement of passenger trains, a diesel locomotive of the TEP70 series is used for diesel traction, and for an AC electric locomotive of the ChS4 series.
It has been established that the annual savings in energy costs for the traction of passenger trains when using passenger cars with a reduced tare weight is about 1 million UAH.
Keywords: passenger car, body, resource, wear, modernization, economic effect.

Biorremediación de suelos alterados por actividades mineras: Soluciones geológico-ambientales y bioeconómicas
Authors: Hernández Rodríguez Juan Camilo , García González Jenny
Published: May 2023

Los procesos de biorremediación se realizan con compost. Específicamente, se usan materiales orgánicos que pasan por un lombricultivo, que finalmente genera un producto orgánico (tierra-abono) utilizado para la recuperación de suelos después de que son afectados por sustancias químicas, maquinaría e intervenciones antropogénicas. Con este material, llamado compostaje, se ha contribuido a la recuperación de zonas mineras durante su operación, en el Municipio de Lenguazaque, Cundinamarca, donde hay proyectos de minería subterránea de carbón coque. La utilización de este material ha permitido que suelos áridos y “contaminados” hayan sido recuperados y reforestados, devolviendo al entorno y al ecosistema del área del proyecto la sinergia entre la actividad desarrollada, la afectación del suelo y su reparación, para que así sea posible retomar su productividad con poca inversión.

Published: May 2023

Morphological characters of soybean can be influenced by shading which are occasionally caused in plants. Thus, this study aimed to evaluate the effect of different shading levels on epicotyl length, epicotyl diameter and height of soybean plants. The experiments were conducted in a greenhouse. When the plants reached the V2 development stage, measurements were taken of epicotyl length and epicotyl diameter in experiment I (conducted in autumn); and epicotyl length, epicotyl diameter, and plant height in experiments II (spring/summer) and III (summer). Each experiments were conducted in a randomized block design, in subdivided plots, with four repetitions. The plots were composed of four shading levels and the subplots were composed of eight conventional cultivars. Each experimental unit consisted of one plant grown in a 3 dm³ pot filled with soil and organic matter. The three characters evaluated in the experiment presented significant effect for the interaction cultivar x shading x sowing seasons. Epicotyl length, independent of the sowing season, increased as the shading level intensified. Both the shading level and the sowing season influenced the diameter of the epicotyl, in a general way, reducing the diameter as the shading level increased. With increasing shading rate there was an increase in plant height. Moreover, the cultivars formed statistically distinct groups for the three morphological characters evaluated.
Nietzsche on the Decadence and Flourishing of Culture Andrew Huddleston
Authors: Chiurco Carlo
Published: May 2023

The main focus of Andrew Huddleston’s book concerns the notion of culture in Nietzsche’s philosophy, and the regrettable oversight it has received from recent scholars, who have overwhelmingly favored discussions of Nietzsche’s valorization of the “great individual." In doing so, the author pays a great service to a more balanced general comprehension and assessment of Nietzsche, showing a certain degree of courage to approach a concept (that of culture), usually closely associated with Marxist philosophical reflection. We tend to forget that, on the contrary, Nietzsche’s philosophical debut—may we say manifesto?—was entirely focused on cultural renovation at large, to the extent that even his conception of the “great individual” of the time—his Schopenhauer-inspired “metaphysics of the genius," notably the artistic genius—shows distinctively supra-individualistic features, with the tragic artist essentially heralding a new era where mankind retrieves an immediate connection with the essence of reality. In this regard, not only is culture a key element of Nietzsche’s philosophy, but the decadence and flourishing of culture—the book’s subject by its title—was arguably one of Nietzsche’s deepest philosophical preoccupations throughout his entire productive life. Therefore, Huddleston’s claim that Nietzsche cannot be judged as a staunch individualist—or at least not just that—is well-supported, just as his suggestion that a paradigm change in Nietzsche studies on this subject would be more than welcome.

Association between optic nerve sheath diameter/eyeball transverse diameter ratio and neurological outcomes in patients with aneurysmal subarachnoid hemorrhage
Authors: Kim Jinsung , Shin Hyungoo , Lee Heekyung
Published: May 2023

Objective : The optic nerve sheath diameter (ONSD)/eyeball transverse diameter (ETD) ratio is a more reliable marker of intracranial pressure than the ONSD alone. We aimed to investigate the predictive value of the ONSD/ETD ratio (OER) for neurological outcomes in patients with aneurysmal subarachnoid hemorrhage (aSAH).Methods : Adult patients with aSAH who visited the emergency department of a tertiary hospital connected to a South Korean university between January 2015 and December 2021 were included. Data on patient characteristics and brain computed tomography scan findings, including the ONSD and ETD, were collected using a predefined protocol. According to the neurological outcome at hospital discharge, the patients were divided into the unfavorable neurological outcome (UNO; cerebral performance category [CPC] score 3–5) and the favorable neurological outcome (FNO; CPC score 1–2) groups. The primary outcome was the association between the OER and neurological outcomes in patients with aSAH.Results : A total of 171 patients were included in the study, of whom 118 patients (69%) had UNO. Neither the ONSD (p=0.075) nor ETD (p=0.403) showed significant differences between the two groups. However, the OER was significantly higher in the UNO group in the univariate analysis (p=0.045). The area under the receiver operating characteristic curve of the OER for predicting UNO was 0.603 (p=0.031). There was no independent relationship between the OER and UNO in the multivariate logistic regression analysis (adjusted odds ratio, 0.010; p=0.576).Conclusion : The OER was significantly higher in patients with UNO than in those with FNO, and the OER was more reliable than the ONSD alone. However, the OER had limited utility in predicting UNO in patients with aSAH.

Published: May 2023

Balamuthia mandrillaris amebic encephalitis (BAE) can cause a fatal condition if diagnosis is delayed or effective treatment is lacking. Patients with BAE have been previously reported in 12 provinces of China, with skin lesions being the primary symptom and encephalitis developing after several years. However, a significantly lower number of cases has been reported in Southwest China. Here we report an aggressive BAE case of a 64-year-old woman farmer with a history of skin lesions on her left hand. She was admitted to our hospital due to symptoms of dizziness, headache, cough, vomiting, and gait instability. She was initially diagnosed with syphilitic meningoencephalitis and received a variety of empirical treatment that failed to improve her symptoms. Finally, she was diagnosed with BAE combined with amebic pneumonia using next-generation sequencing (NGS), qRT-PCR, sequence analysis, and imaging studies. She died approximately 3 weeks after the onset. This case highlights that the rapid development of encephalitis can be a prominent clinical manifestation of Balamuthia mandrillaris infection.
From Genes to Circuits
Authors:   , Rybiczka-Tesulov Mateja
Published: May 2023

The interaction of a myriad of molecular factors is necessary for proper development of mDA circuitry. Although significant progress has been made in uncovering the mechanisms involved in mDA neuron development, our understanding of the role played by specific classes of molecules (such as non-coding RNAs) is still incomplete. To extend existing knowledge, we examined the cellular aspects of mDA neuron development (chapter 1). Using this information, we identified relevant timepoints for a comprehensive transcriptomic profiling study of mouse mDA neurons and employed bioinformatics analysis to uncover patterns of lncRNA and circRNA expression during embryonic and postnatal development (chapter 1). We selected specific circRNA candidates for further functional investigation (chapter 2). Through in vitro and in vivo knockdown of a particular circRNA, we discovered several cellular and molecular changes in normal mDA neuron development.

Advances in sequencing techniques have facilitated the assessment of molecular profiles at the single-cell level in a more efficient and rapid manner. However, the definition of subtypes remains a subject of debate. Therefore, to gain a better understanding of the extent of mDA system heterogeneity, it is crucial to study cellular properties, such as morphology and electrophysiology. Consequently, we utilized intersectional mouse genetics to investigate different subsets of mDA neurons and their individual morphology (chapter 3).

The mDA system can be broadly categorized into the VTA and the SNc. These two regions receive and respond to distinct molecular signals that guide the neurons to their final positions after birth. In chapter 4, we made a novel discovery regarding a long-range mechanism that promotes cellular migration. Furthermore, we demonstrate the importance of the localization of other cell types (specifically, GABAergic neurons) for the proper placement of mDA neurons.

The author attempts to identify how the image of the state is formed on the example of China. The article reveals theoretical approaches to the concept of “the image of the state” and demonstrates how it can be used in practice. In particular, the author examines the issues of symbols, stereotypes that are formed by the state. The author analyzes the influence of culture as the most important tool of “soft power” on the image of China. The article notes the significance of the semantic content of the political image, which can be compared with a kind of source, which at the subconscious level sets a certain angle of perception of new information about this political object. The choice of an image that will then be purposefully formed in the mass consciousness and forms the image of both all states in general and China in particular. And the more precisely the compliance of the environmental, political, economic, demographic and other situations in the country with the interests of the public is manifested, the more positive the image of the country, the more
RELIGIOUS POLICY OF JAPAN IN THE XV-XVII CENTURIES IN THE CONTEXT OF CENTRALIZATION OF AUTHORITY AND THE EMERGENCE OF REALISTIC AUTHORITARIANISM
Authors:   National Research University “Higher School of Economics”, Moscow, Russian Federation, FILIPPOV ANTON
Published: May 2023

This publication attempts to study the religious policy of Japan from the time of the unification of the country through the efforts of Oda Nobunaga and Toyotomi Hideyoshi to the consolidation of the Tokugawa shogunate in close connection with the ongoing political processes - the centralization of authority and the formation of the Tokugawa military oligarchy based on realistic authoritarianism. The significance of the ideological postulates of the religions common in pre-Edo and Edo Japan is established in the context of overcoming feudal fragmentation and the consistent construction of the Tokugawa shogunate. The main directions of the state religious policy of the period under review are singled out and the nature and political reasons for the positive or negative attitude towards common religions on the part of the ruling class are revealed. The understanding of realistic authoritarianism as a set of methods for retaining Tokugawa power by harsh, manipulative, but excluding direct violence methods is being consolidated. The thesis is substantiated that the Confucian doctrine became the ideological basis for the centralization of authority and the emergence of realistic authoritarianism of the first Tokugawa shoguns, the implementation of which made it possible to establish the regime of the Tokugawa military oligarchy through the policy of “soft power”, blocking the emergence of centrifugal and separatist tendencies among influential daimyo. It is proved that the state during the period under review pursued a conservative religious policy which was expressed in the patronage of traditional beliefs (Shintoism, Buddhism and Zen Buddhism) and the prohibition of Christianity, which was perceived, on the one hand, as a belief alien to the Japanese and, on the other hand, as a worldview that encroaches on the foundations of Japanese statehood. In the context of the study of religious policy towards Christians, it is concluded that the Confucian idea of achieving state order by unifying social life and consistently getting rid of political and axiological factors that could bring disorganization into normal and habitual functioning of social matter played a significant role in the prohibition of Christianity and Catholic missionary work.

Energi matahari adalah salah satu pilihan energi alternatif. Energi matahari akan diubah menjadi energi listrik oleh panel suya, namun kondisi cuaca yang tidak menentu mengakibatkan adanya perubahan suhu dan intensitas cahaya, yang menyebabkan tegangan dan arus keluaran dari panel surya menjadi tidak stabil. Oleh karena itu, konverter DC-DC diperlukan sebagai pengendali keluaran panel surya. Konverter DC-DC memiliki banyak topologi, salah satunya adalah topologi Zeta dimana tegangan keluaran konverter Zeta ditingkatkan lebih dari tegangan keluaran yang dihasilkan konverter Boost. Pengendalian keluaran panel surya dilakukan menggunakan metode Maximum Power Point Tracker (MPPT) dengan algoritma Perturb and Observe (P&O) untuk mencari titik daya maksimum yang dihasilkan panel surya. Dari penggunaan konverter zeta dengan metode MPPT P&O pada panel surya didapatkan nilai titik daya maksimum pada tegangan sebesar 23,9V dengan arus adalah 1,4A dan menghasilkan daya masukan sebesar 33,46W, dimana titik daya maksimum panel surya tersebut merupakan nilai daya yang paling optimal panel surya. Dari daya masukan tersebut menghasilkan nilai daya keluaran sebesar 24W.

Pohon palem merupakan tumbuhan asli daerah tropis. Di wilayah Indonesia, dapat ditemui hampir di seluruh provinsi dari Sabang sampai Merauke, mulai dari pantai, dataran rendah hingga dataran tinggi. Pelepah pohon palem selama ini hanya dianggap sebagai sampah. Bentuknya yang besar dan dan kasar membuatnya sulit untuk dimanfaatkan. Pada akhirnya pelepah-pelepah pohon palem tersebut hanya akan dibuang dan dibakar oleh masyarakat sekitar tanpa ada ide untuk memanfaatkannya menjadi barang yang berguna dan mempunyai harga jual tinggi. Pada penelitian ini dirancang alat pengepres pelepah pohon palem menjadi piring menggunakan kontrol PLC. Alat pengepres pelepah pohon palem ini menggunakan sensor RTD PT100 sebagai pengukur dan pembacaan suhu pada cetakan (mold), PLC CP1H sebagai kontrol, serta memanfaatkan kontrol PID yang bertujuan untuk mempercepat dan menstabilkan suhu pada setpoint. Nilai yang didapat pada kontrol PID ini yaitu dengan Kp sebesar 4, Ti sebesar 2168, Td sebesar 524 dengan setpoint 120˚ derajat C dan lama pengepresan 40 detik akan menghasilkan piring yang bagus dari pelepah pohon palem.
