Published: April 2023

Indonesian automatic text summarization research is developed rapidly. The quality, especially readability aspect, of text summary can be reached if the meaning of the text can be maintained properly. Therefore, this research aims to enhance the quality of extractive Indonesian automatic text summarization with considering the quality of structured representation of text. This research uses sequential pattern mining (SPM) to produce This research use SPM to produce sequence of words (SoW) as structured text representation using PrefixSpan algorithm. Then, SPM is combined with feature-based approach using sentence scoring method to produce summary. The experiment result using IndoSum dataset shows that even though the combination of SPM and sentence scoring can increase the precision value of recall-oriented understudy for gisting evaluation (ROUGE)-1, ROUGE-2, and ROUGE-L, from 0.68 to 0.76, 0.54 to 0.69, and 0.51 to 0.72. Especially, combination of SPM and Sentence Scoring can enhance precision, recall, and f-measure of ROUGE-L that consider the order of word occurance in measurement. SPM increases ROUGE-L f-measure value of sentence scoring from 0.32 to 0.36. Moreover, combination of sentence scoring and SPM is better than SumBasic that used as feature-based approach in the previous Indonesian text summarization research.

Authors: Gaffarova Liliya , Belyaev Sergey
Published: April 2023

The results of the analysis of materials of a large-scale soil and agrochemical survey, morphological structure and properties of representatives of forest-steppe soils of the northern part of the Aktay-Shentalinsky landscape lowland region of the Republic of Tatarstan are shown. The territory is a poorly divided polygenetic plain with absolute heights of 140-150 m. The bedrock deposits have sandy-loamy layers of the Neogene and Pleistocene, overlain by cloaks of Quaternary deluvial loams, up to 20-21 m thick. The soil cover is dominated by leached medium–sized chernozems, which is 52.6% of the area, typical low–power and medium-sized chernozems - 39.6%, podzolized medium-sized chernozems - 2.7%, gray forest – 4.8%. The humus content in the agrogenic horizon of typical chernozems is average – 4.2-5.2%, and in leached chernozems ranges from 4.6% in a slightly washed analogue to 5.4% in full-profile representatives, where the humus content gradually decreases to the soil-forming rock. The potential reserves of humus of the studied subtypes of chernozems according to typical sections are in the range from 230 t/ha to 462 t/ha. According to the materials of the agrochemical survey for 1972-2021, the dynamics of the content of mobile forms of phosphorus in the arable horizon ranged from 103 mg/kg to 158 mg/kg. The weighted average amount of mobile potassium gradually decreased from 140 mg/kg to 101 mg/kg of soil. The actual yield of spring wheat and the dynamics of the content of mobile forms of potassium over the years of observation have a reliable correlation between each other. The obtained regression equations can be used to predict the yield of spring wheat in a given area. According to the results obtained, for each hectare of arable land for 51 years, about 149.9 kg of phosphorus was received with organic and mineral fertilizers, and since it is sedentary and difficult to dissolve, this led to its accumulation in the soils of the territory. The potassium balance is negative and amounted to -775.9 kg.

Published: April 2023

Based on the typical dielectric materials and devices of satellite, a surface charging and dose monitor (SCAD) was developed to measure the surface charging voltage, current, and dose under different shielding depths. The SCAD has been successfully launched into orbit on June 23, 2020. The measurement results on orbit show that the SCAD works normally, and the data of SCAD are reasonable. The results show that the radiation dose rate on geosynchronous orbit is about 0.4 mrad(Si)/s, and the maximum charging voltage is about −800 V during the initial measuring period. The charging voltage is consistent with the trends of geomagnetic disturbance Kp index. The on-orbit data provide basic data on surface charging and discharging effect and total dose effect, supporting the safe and reliable operation of the satellite.
Effect of different proportions of CNTs/Fe3O4 hybrid filler on the morphological, electrical and electromagnetic interference shielding properties of poly(lactic acid) nanocomposites

Published: April 2023

Due to the shortage of petroleum resources, poly(lactic acid) (PLA), a biodegradable polymer, has been widely considered as a replacement for traditional petroleum-based polymers. Therefore, multifunctional PLA composites have become increasingly popular. In this study, conductive carbon nanotubes (CNTs) and magnetic nano-Fe3O4 fillers were melt-blended with PLA. The impact of CNTs and nano-Fe3O4 composition on the electrical and electromagnetic interference (EMI) shielding properties of PLA nanocomposites was investigated in detail by adjusting the CNTs-to-nano-Fe3O4 ratio. When the hybrid filler content was fixed at 10 wt%, the electrical conductivity results indicated that the addition of single CNTs could effectively improve the conductivity of the nanocomposites, while nano-Fe3O4 contribution was hardly noted. A suitable ratio of electromagnetic hybrid fillers can yield excellent synergistic effects in EMI shielding properties. The nanocomposites containing CNTs and nano-Fe3O4 in a 50:50 ratio exhibited excellent electrical conductivity (90.6 S·m−1) and EMI shielding effectiveness (EMI SE ∼ 40.5 dB). This is primarily because CNTs provide good electrical conductivity, but the addition of magnetic nano-Fe3O4 provides additional interfacial polarization and eddy current losses caused by its dielectric and magnetic properties. These properties synergistically result in an impedance mismatch, dielectric loss, and polarization relaxation of the composite materials, improving the shielding properties against electromagnetic waves. Further, it was found that changing the ratio of electromagnetic hybrid fillers also affected electromagnetic wave absorption. When the ratio of CNT-to-nano-Fe3O4 was 25:75, the nanocomposites had an EMI SE of 24.6 dB, and the absorptivity could reach the maximum (40.3%). Thus, this study provides a valuable reference for preparing multifunctional polymer nanocomposites by constructing electromagnetic hybrid filler networks.
Homogeneous ACM bundles on isotropic Grassmannians
Authors: Du Rong , Fang Xinyi , Ren Peng
Published: April 2023

In this paper, we characterize homogeneous arithmetically Cohen–Macaulay (ACM) bundles over isotropic Grassmannians of types 𝐵, 𝐶 and 𝐷 in terms of step matrices.
We show that there are only finitely many irreducible homogeneous ACM bundles by twisting line bundles over these isotropic Grassmannians.
So we classify all homogeneous ACM bundles over isotropic Grassmannians combining the results on usual Grassmannians by Costa and Miró-Roig.
Moreover, if the irreducible initialized homogeneous ACM bundles correspond to some special highest weights, then they can be characterized by succinct forms.

Authors: Yuan Ding , Liu Jialiang , Sang Wenbo , Li Qing
Published: April 2023

The sideroflexin (SFXN) family is a group of mitochondrial membrane proteins. Although the function of the SFXN family in mitochondria has been widely recognized, the expression levels, role, and prognostic value of this family in breast cancer (BC) have not been clearly articulated and systematically analysed. In our research, SFXN1 and SFXN2 were significantly upregulated in BC versus normal samples based on Gene Expression Profiling Interactive Analysis 2 and the Human Protein Atlas databases. We found that high SFXN1 expression was significantly related to poor prognosis in BC patients and that high SFXN2 expression was significantly associated with good prognosis in BC patients. Gene Ontology analysis of the SFXN family was performed based on the STRING database to explore the potential functions of this family, including biological processes, cellular components, and molecular functions. Based on the MethSurv database, we found that two SFXN1 CpG sites (5′-UTR-S_Shelf-cg06573254 and TSS200-Island-cg17647431), two SFXN2 CpG sites (3′-UTR-Open_Sea-cg04774043 and Body-Open_Sea-cg18994254), one SFXN3 CpG site (Body-S_Shelf-cg17858697), and nine SFXN5 CpG sites (1stExon;5′-UTR-Island-cg03856450, Body-Open_Sea-cg04016113, Body-Open_Sea-cg04197631, Body-Open_Sea-cg07558704, Body-Open_Sea-cg08383863, Body-Open_Sea-cg10040131, Body-Open_Sea-cg10588340, Body-Open_Sea-cg17046766, and Body-Open_Sea-cg22830638) were significantly related to the prognosis of BC patients. According to the ENCORI database, four negative regulatory miRNAs for SFXN1 (hsa-miR-22-3p, hsa-miR-140-5p, hsa-miR-532-5p, and hsa-miR-582-3p) and four negative regulatory miRNAs for SFXN2 (hsa-miR-9-5p, hsa-miR-34a-5p, hsa-miR-532-5p, and hsa-miR-885-5p) were related to poor prognosis for BC patients. This study suggests that SFXN1 and SFXN2 are valuable biomarkers and treatment targets for patients with BC.
The role of social networks in academic discourse socialization: insights from degree-seeking multilingual international students in China
Authors: Li Wendong , Gong Yang
Published: April 2023

This study adopted a social network perspective to explore the academic discourse socialization experiences of eight degree-seeking multilingual international students at a university in eastern China. Based on a triangulation of ethnographic interviews, social network questionnaires, and supplementary sources (e.g., voluntarily submitted recordings, texts about academic exchanges), the study revealed five patterns of students’ social networks, including heterogeneous-sparse network, heterogeneous-dense network, homogeneous-sparse network, homogeneous-dense network, and balanced network. This resulting network typology was utilized to interpret the role of social networks in individuals’ socialization trajectories, which were observed to include affecting capacities to negotiate academic norms, structuring channels to build and transform expertise, and shaping space for multicompetence development. While different network connections demonstrated different roles, networks with similar characteristics could exert divergent impacts, highlighting the mediation of a range of individual and sociocultural dynamics. Based on the findings, the study contributes to critical multilingual studies by offering theoretical implications for socialization research on community and competence, and providing practical suggestions for research, education, and program administration in international education.
Rechtfertigung und Selbsterhöhung nach der „Nacht der langen Messer“
Authors: Siemens Daniel
Published: April 2023

Nach der Ermordung Ernst Röhms am 1. Juli 1934 ernannte Adolf Hitler Viktor Lutze zum neuen Stabschef der Sturmabteilung (SA), ein Amt, das dieser bis zu seinem Unfalltod im Mai 1943 innehatte. Bereits im Sommer 1934 begann er mit der Niederschrift politischer Aufzeichnungen, die je nach Eintrag und Zeitabschnitt zwischen Tagebuch, monatlicher Rückschau und Autobiografie changieren. Diese wichtige autobiografische Quelle eines hochrangigen NS-Politikers wird hier erstmals in Auszügen veröffentlicht und durch eine ausführliche Einleitung kontextualisiert. Das Dokument zeigt die strategischen Überlegungen des Stabschefs und wirft Schlaglichter auf die Probleme der Organisation im Gefüge der polykratischen NS-Herrschaft. Lutzes Schilderung der Ereignisse zwischen Ende Juni und Mitte Juli 1934 ist zudem eine der wichtigsten Quellen für die Geschichte der Röhm-Aktion.

Published: April 2023

The coal is an imperative source of energy, which on combustion, it emits sulphur dioxide, which cause air pollution. In the present study, microwave mediated desulphurization of coal was investigated and input variables were optimized by response surface methodology (RSM). The proximate analysis and ultimate analysis report indicate the sample belongs to subbituminous having sulphur (6.96%), volatile matter (34.5%) and calorific value (5099 kcal/kg). Under microwave irradiation, up to 68% of sulphur was leached in alkaline medium. The particle size of coal, concentration of potassium hydroxide (KOH), microwave exposure time and power of microwave radiation were systematically optimized for maximum desulphurization of the coal. Under optimum conditions of the process variables, 63.06% desulphurization of coal was achieved. The optimum levels of process variables are as, particle size 500 µm, irradiation time 8.54 min, radiation power 720 W and concentration of KOH 15% (w/v). Findings revealed that the microwave-assisted desulphurization under alkaline condition furnished promising efficiency, which can be employed for the desulphurization of coal.
Role of arbuscular mycorrhizal fungi in cadmium tolerance in rice (Oryza sativa L): a meta-analysis
Authors: Li Ximei , Jing Ruiyong , Wang Liyan , Wu Nan , Guo Zhenhua
Published: April 2023

Rice is an important agricultural product consumed globally. Rice polluted by cadmium (Cd) poses serious health risks. Numerous studies have shown that arbuscular mycorrhizal fungi (AMF) decrease Cd concentrations in the grain, shoots, and roots of rice. However, one study showed that AMF increased the root Cd concentration in rice. Therefore, a meta-analysis of the contribution of AMF to rice Cd tolerance became necessary. This meta-analysis was conducted to analyze the role of AMF in Cd tolerance in rice by searching the following databases: ProQuest, PubMed, Scopus, and ScienceDirect. A total of 571 studies were found, of which nine studies and 25 datasets were used in the meta-analysis. The period of inclusion of research reports was from January 1992 to April 2022. The results showed that with the addition of Rhizophagus irregularis, Cd concentration in the roots was higher than in the control group, although the overall Cd concentration in the plant was reduced. Four species of AMF reduced Cd concentration in rice shoots and grain tissues. These AMF species increased the biomass of rice root and shoot tissues; however, they did not affect grain biomass. AMF decreased the transfer factor (TF), and the TF of Glomus versiforme (12.99%) was significantly lower than the other three AMF types. We proposed that Cd could be enriched in rice roots, and the transfer of Cd to the grain could be inhibited. At the time of grain harvesting, rice roots are removed from the soil, thus removing Cd from the soil. This operation can efficiently improve both land-bearing capacity and soil without affecting rice yield. Thus, Cd was enriched in rice roots, and the poten-tial for Cd transfer to the grain was inhibited due to the decreased TF. The future research must focus on how R. irregularis could improve the HMA3 gene expression in rice root, and prevents the transportation of Cd from the roots to shoots.

Published: April 2023

Temperature plays a crucial role in the storage of meat. Low temperature effectively slows down the growth rate of microorganisms and enzymatic activity that causes meat spoilage. Frozen storage of meat allows consumers to choose meat’s date of consumption during storage without losing its sensory quality. This work is committed to the effects of freezing and refrigeration on quality and safety of food. The study aims to determine whether different frozen storage temperatures and duration affect the quality of raw goose meat and its processing characteristics after thawing. This information could be a valuable contribution to the scientific literature concerning storage of meat. The focus was on goose meat and sausages. The meat was frozen in three independent runs for 3 and 6 months at -20°C and -70°C. The thawed meat was subjected to physicochemical and microbiological analyses and then turned into raw sausages. Frozen meat sausages showed significantly higher thiobarbituric acid (TBA) values after 2 and 4 weeks of the experiment, compared to the control group. Frozen storage also reduced the growth of Pseudomonas spp. and Enterobacteriaceae for all storage temperatures. Findings of the present study could be used to preserve quality and taste of products during meat processing.

Published: April 2023

This study aims to investigate the potential of mixing jackfruit seed flour (JFSF) with pasta and its effects on techno-functional properties, cooking behavior, textural characteristics, morphology, macromolecular interactions, and secondary structure of proteins of pasta. The results showed with increase in the addition of JFSF from 6 to 24% caused significant (P < 0.05) improvement in the functional properties, decline in the minimum cooking time (7.07 to 6.20 min), and an increase in the cooking loss (5.13 to 11.26%) as well as firmness of the pasta. Organoleptic evaluations indicated the incorporation of JFSF up to 18% without affecting the flavor. Scanning electron microscopy revealed that after cooking bell-shaped starch granules were embedded in the protein matrix. Fourier transform infrared spectra analysis of the secondary structure of protein showed that the major protein fractions were β-sheets, followed by β helix. Positive correlations between cooking losses and water solubility index and several other parameters were established using principal component analysis. Therefore, incorporating JFSF into pasta could be a promising way for developing protein-rich, high-quality pasta with improved nutritional and functional properties.

Published: April 2023

Staphylococcus aureus, a prominent pathogen, is frequently encountered in clinical and food-processing settings. Given its ability to develop antimicrobial resistance, effective control strategies are required to ensure microbial safety. In this study, four lytic S. aureus phages (SapYZU10, SapYZU11, SapYZU12, and SapYZU13) were isolated from sewage samples in Yangzhou, China. Their biological characteristics and bactericidal effect against S. aureus isolates in vitro and in milk and fresh pork were evaluated. Their activities remained relatively stable under stressful conditions (-80–70°C, pH 3.0–12.0). Notably, SapYZU11 (100%, 53/53) effectively lysed all 53 S. aureus strains, followed by SapYZU12 (90.57%, 48/53), SapYZU13 (79.25%, 42/53), and SapYZU10 (71.70%, 38/53). Among the phages with short latent periods (10–20 min), SapYZU11 had a larger burst size (152.00 plaque forming units [PFU]/mL) and no genes related to antibiotic resistance and virulence. Furthermore, SapYZU11 effectively eradicated S. aureus and its cocktail (YZUsa1, YZUsa4, YZUsa12, YZUsa14, and methicillin-resistance S. aureus (MRSA) JCSC 4744) in Luria–Bertani broth and both food items. Particularly in milk, SapYZU11 with a multiplicity of infection (MOI) of 100 inhibited MRSA JCSC 4744 strain and S. aureus cocktail with maximum reduction levels of 5.03 log (Lg) colony-forming unit (CFU)/mL and 2.80 Lg CFU/mL, respectively. Conversely, contaminated pork treated with three MOIs of SapYZU11 at 25°C and 4°C resulted in reductions of 0.29–1.29 Lg CFU/mL and 0.11–0.32 Lg CFU/mL, respectively. Therefore, SapYZU11 proved as a promising biocontrol agent against S. aureus in different food production settings.

Published: April 2023

The world economic development nowadays is characterised by the significance of digital innovations and sustainable development in all areas of production and management. However, the existing literature still cannot explain how environmental, economic and social factors of sustainable development corresponding to these innovations affect the new global ecosystem, based on the introduction and adaptation of digital technologies and achievement of the United Nations Sustainable Development Goals (SDGs) at the national level. The article presents the results of the authors’ assessment and classification of countries according to the achievement of the SDGs and implementation of digital innovations in the national and global economy. The empirical analysis utilises the data on the digitalisation performance indicators of the Global Innovation Index (GII) and the Sustainable Development Goals Index (SDG Index). The country assessment matrix was classified in terms of digitalisation and sustainable development and tested on a sample of European countries. Cluster analysis of 39 European countries identified four homogeneous clusters, which have distinctive systemic characteristics: advanced countries, catching-up countries, locomotive countries and leaders in sustainable and digital development. The identified clusters ex-pand the possibilities for substantiating socio-economic and technological strategies at the country – region – industry level. Russia is revealed as one of the eleven catching-up countries. The paper specifies the directions of the strategy to achieve the target digitalisation and sustainable development in the process of integration of the SDGs into national indicators. The proposed assessment can be used to adjust the state policy for the co-development of digital innovations and sustainable development indicators.
A Model for Assessing Regional Sustainable Development Based on the Index Method
Authors:   Saint Petersburg State University, Borodin S. N.
Published: April 2023

Assessment of development opportunities for socio-economic systems is particularly relevant in the context of constantly changing macroeconomic conditions. A retrospective analysis is an important step in assessing development opportunities at the regional level. Based on a presented model for assess-ing regional sustainable development, the article analyses statistical data of the regions included in the Central, Northwestern and Southern Federal Districts for the period 2005-2019. According to the concept of sustainable development, the indicators were divided into three subgroups: social, economic and environ-mental. The following results were obtained. Social indicators revealed positive dynamics in the number of regions developing sustainably until 2014; later, the number changed erratically every year, ranging from 21 to 38. Economic indicators demonstrated negative dynamics in the number of sustainable regions un-til 2014. In the period 2014-2019, an abrupt fluctuation from 13 to 32 units was observed. Environmental indicators show that, on average, half of the examined regions managed to develop sustainably. After de-termining the overall index, the rate of change of the index was identified. Then, a sustainable develop-ment matrix was constructed, where 1 means that the index value increased year-on-year or remained the same, and 0 means that the index value decreased year-on-year. The findings can be used for ranking re-gions by summing up values in the region’s row of the sustainability matrix. The study may also serve as a basis for identifying the relationship between various large-scale phenomena such as the economic crisis, pandemic, the development of digital currency markets and changes in regional sustainability indicators.
Tracing the Transformation of the US’s Hegemonic Paradigm in the Historical Process: From Embedded Liberalism to Disembedded Financial Liberalism
Authors: SARI AKSAKAL Betül
Published: April 2023

The emergence of the United States (US) as the worldwide dominant power is an affair that needs to be investigated in light of some historical experiences. Afterward the Second World War, the US reestablished the world’s deteriorating international monetary and financial system. Embedded liberalism reinforced and stabilized the US hegemony (as the form of economic, political, and institutional organization) by generating the requirements for consolidating the global economy in which the US takes a leading role. From the mid-1970s, after integrating the world economy into an accumulation regime characterized by finance capital-as, a natural consequence of the transition to neoliberal policies-it was understood that fragmented financial liberalism began to show its effect as a new strategy that would ensure the continuity of the US hegemony. The study has departed from the problematic of elucidating the change in the hegemonic strategy of the US from its birth to the present day. In this problematic context, the shift of the US hegemonic strategy from embedded liberalism to disembedded financial liberalism and the central dynamics determining this shift is examined in the axis of historical perspective.

Published: April 2023

Asgari ücret, bir kişinin temel ihtiyaçları olarak öngörülen ihtiyaçlarının karşılanması düzeyinde belirlenen en düşük ücret olarak tanımlanmaktadır. Devlet açısından asgari ücret; gelir dağılımında adaletin sağlanmasına yönelik önemli bir politika aracı olurken, işveren için bir maliyet unsuru, işçi açısından ise yaşamın idame ettirilmesi adına önem taşımaktadır. Özellikle son dönemlerde gündemini koruyan bir konu haline gelmiştir. Bunun yanında asgari ücret ülke ekonomik unsurlarını da yakından ilgilendirmekte ve etkilemektedir. Asgari ücret miktarındaki artışın enflasyon, harcamalar, vergi gelirleri, büyüme, istihdam gibi hususlarda da değişimlere sebep olduğu görülmektedir. Bu çalışmada makroekonomik değişkenlerdeki değişimlerin asgari ücret kadarının vergi dışı bırakılmasına etkileri araştırılmıştır. Bu amaçla Türkiye’nin 1997-2022 yılları baz alınarak TÜİK’den elde edilen 25 yıllık veri seti kullanılmış ve zaman serisi analiz yöntemi kullanılarak ülke ekonomisinde oluşturduğu etkiler üzerine çalışılmıştır.

Published: April 2023

As online learning becomes widespread in education field especially higher education, researchers showed great interest in identifying factors that affect students’ satisfaction with online courses. This study aimed at examining EFL undergraduate students’ satisfaction with online English courses in Jordanian universities. More specifically, it aims at investigating the role of interaction as a predicator for EFL students’ satisfaction with online English language courses. It is a quantitative approach. The researchers collected data by administering an online Microsoft Teams form to 189 undergraduate EFL students. One hundred and twelve responded to the five-Likert scale questionnaire. The accepted forms are 105. By applying the statistical method of SPSS, regression findings showed that the four-predictor variables (student-content interaction, student-instructor interaction, student-student interaction and student-technology interaction) affect positively students’ satisfaction with online English language courses. The study found that student-technology interaction and student-instructor interaction were the strongest and most significant predictors of student satisfaction with online English language courses. Moreover, findings showed statistically significant differences for the effect of students' interaction on students' satisfaction due to the students’ past online learning experience. This study helps the university instructors to understand the factors that contribute to the students’ satisfaction, which ultimately lead to an effective online learning. It also builds on the findings of previous studies that necessitate the need for much attention to two types of interaction: student-student and student-content.

Published: April 2023

The purpose of this cross-sectional observational study is to show how the perception of returnees’ L2 can be changed in the digital era and how the massive spread of technology, among other factors, has eased an Arab (Saudi) returnee child’s maintenance of English as an L2. The study discusses how technology allowed the returnee to continue to receive abundant L2 input, use the L2 daily, and interact with native speakers. The child was 9 months old when his family moved to the United States and was 6.2 years old when returned to Saudi Arabia. The study took place 5.4 years after their return when his age was 11.6 years old. A free conversation with the child, observation of online gaming, and an interview with parents were conducted to observe the child’s L2 maintenance. The child demonstrated an intermediate level of fluency and produced non-verbal communication in free conversation and online gaming. The parents held positive attitudes toward bilingualism and English which was believed to have a great influence on the child’s L2 maintenance. The study concludes that technology, parental attitudes, and personality and motivation have all contributed to the child’s successful L2 maintenance.

Paper chromatography is a method that allows rapid assessment of the
condition and identification of fuel, water and soot contaminants in
engine oil. The paper contains an analysis of the suitability of rapid paper
chromatography for assessing the operating quality of engine oil. It takes
into account the comparison of physicochemical parameters by classical
methods with the quality of commercial paper chromatography. The
presented research allowed verifying the suitability of paper
chromatography for laboratory evaluation of engine oil quality. It was
found that a more extensive analysis of the oil condition is possible
provided that the chromatographic separation time of oil dispensed onto
filter paper is increased from 1 minute to 40 minutes. Linear
relationships were observed between the surface area of the stain core
after 40-minute separation and selected viscosity parameters (e.g.
kinematic viscosity measured at 40° C). Based on rapid paper
chromatography, it was found that reasonable decisions can be made
about the quality of engine oil, and thus about replacement or further use
of the oil.

Published: April 2023

BACKGROUND: Absence epilepsy is one of the most common epileptic syndromes and is more common in girls. Often in adolescence, generalized tonic-clonic seizures (up to 50%) join. In women suffering from epilepsy, reproductive dysfunction is often noted. In this regard, it seems relevant to study the morphofunctional state of the ovaries in absence epilepsy.
AIM: Assessment of morphological and morphometric parameters of the ovaries in absence epilepsy.
MATERIALS AND METODS: Using histological and morphometric methods, the ovaries of Wistar and WAG/Rij rats (a genetic model of human absence epilepsy) were studied.
RESULTS: In WAG/Rij rats, destruction of the cortical and medulla of the ovary was found: the layer of granulosa cells surrounding the oocyte had a looser structure compared to the norm, destructive changes in the follicular epithelium and apoptotic death of granulosa cells were observed. Morphometric analysis showed that in WAG/Rij rats the weight of the ovaries was 2 times less than in Wistar rats: 37.300.93 mg versus 55.842.36 mg. The thickness of the epithelial layer was 7.810.25 m, which is 26.2% less than in Wistar rats (p 0.05). The ovarian follicles of WAG/Rij rats were irregular in shape, smaller in diameter and area, and the numerical density of all types of follicles was lower compared to Wistar rats, which indicates a violation of ovulation processes.
CONCLUSION: Structural and quantitative changes in the ovaries of WAG/Rij rats were observed in absence epilepsy, which indicates violations of the endocrine function of the ovaries and process of folliculogenesis.

Published: April 2023

Electric wheelchair-mounted robotic arms can help patients with disabilities to perform their activities in daily living (ADL). Joysticks or keypads are commonly used as the operating interface of Wheelchair-mounted robotic arms. Under different scenarios, some patients with upper limb disabilities such as finger contracture cannot operate such interfaces smoothly. Recently, manual interfaces for different symptoms to operate the wheelchair-mounted robotic arms are being developed. However, the stop the wheelchairs in an appropriate position for the robotic arm grasping task is still not easy. To reduce the individual’s burden in operating wheelchair in narrow spaces and to ensure that the chair always stops within the working range of a robotic arm, we propose here an operating system for an electric wheelchair that can automatically drive itself to within the working range of a robotic arm by capturing the position of an AR marker via a chair-mounted camera. Meanwhile, the system includes an error correction model to correct the wheelchair’s moving error. Finally, we demonstrate the effectiveness of the proposed system by running the wheelchair and simulating the robotic arm through several courses.
Estimation of Liquid Level in a Harsh Environment Using Chaotic Observer

Published: April 2023

The increased demand for liquid level measurement has been a key factor in designing accurate and reliable control systems. Here, a study was carried out to calculate the liquid level in a tank using a pressure sensor for changes in inlet liquid parameters like temperature, density and velocity. Prediction of their variables for the long term is essential due to the randomness present in the input and measurement. Hence, observer design for state estimation of a non-linear dynamic system with uncertainties in the measurement and process becomes important. This work provides a feedback observer solution for a system with multiple inputs and single measurable output. A full state observer model is developed to estimate a system’s states with a sensor placed at a definite position from the pipe’s input point through which the liquid flows at different densities and temperatures. Using the observability properties, Luenberger full state observer is designed by various methods, verified using MATLAB and SIMULINK for the system state estimation. To incorporate process noise and measurement noise, the Kalman estimator is integrated with the system. Chaotic systems are susceptible to initial conditions, variations in parameters and are complex dynamic systems. However, providing consistently precise measurements through particular meters necessitates time-consuming computations that can be reduced by employing machine learning approaches that make use of optimizers. The results obtained are compared with the prediction models obtained using Artificial Neural Networks and are validated through the readings obtained from the experimental setup.

Published: April 2023

Pneumatic robot is a fluid dynamic based robot system which possesses immense uncertainties and nonlinearities over its electrical driven counterpart. Requirement for dynamic motion handling further challenged the implemented control system on both aspects of interaction and compliance control. This study especially set to counter the unstable and inadaptable proportional motions of pneumatic robot grasper towards its environment through the employment of Variable Convergence Rate Prescribed Performance Impedance Control (VPPIC) with pressure-based force estimation (PFE). Impedance control was derived for a single finger of Tri-finger Pneumatic Grasper (TPG) robot, with improvement being subsequently made to the controller’s output by appropriation of formulated finite-time prescribed performance control. Produced responses from exerted pressure of the maneuvered pneumatic piston were then recorded via derived PEE with adherence to both dynamics and geometry of the designated finger. Validation of the proposed method was proceeded on both circumstances of human hand as a blockage and ping-pong ball as methodical representation of a fragile object. Developed findings confirmed relatively uniform force sensing ability for both proposed PEE and load sensor as equipped to the robot’s fingertip with respect to the experimented thrusting and holding of a human hand. Sensing capacity of the estimator has also advanced beyond the fingertip to enclose its finger in entirety. Whereas stable interaction control at negligible oscillation has been exhibited from VPPIC against the standard impedance control towards gentle and compression-free handling of fragile objects. Overall positional tracking of the finger, thus, justified VPPIC as a robust mechanism for smooth operation amid and succeed direct object interaction, notwithstanding its transcendence beyond boundaries of the prescribed performance constraint.
