Removal of silver from chloride solutions using new polymer materials
Authors: Pilśniak-Rabiega Magdalena , Wolska Joanna
Published: October 2023

This work presents the synthesis of polymer resins with heterocyclic functional groups, that is, N-(3-aminopropyl)-2-pipecoline, N-(3-aminopropyl)-2-pyrrolidinone, and trans-1,4-diaminocyclohexane for the recovery of Ag(I) from chloride solutions. The modification yield was 69.2, 74.6 and 88.3%, respectively. The best Ag(I) sorption was achieved from synthetic and real chloride solutions in the case of trans-1,4-diaminocyclohexane resin (sorption was 26.8 and 21.5 mg/g, respectively). The sorption kinetic data were well fitted to the pseudo-first-order kinetic model. The maximum sorption capacity of Ag(I) is 105.4, 117.8 and 130.7 mg Ag(I)/g for N-(3-aminopropyl)-2-pipecoline resin, N-(3-aminopropyl)-2-pyrrolidinone resin and trans-1,4-diaminocyclohexane resin, respectively. The trans-1,4-diaminocyclohexane modified resin was very selective towards Ag(I) compared to Cu(II), Pb(II), and Zn(II) from the real chloride leaching solution. The N-(3-aminopropyl)-2-pipecoline and N-(3-aminopropyl)-2-pyrrolidinone resins showed high preferences for Ag(I) over Pb(II) in real solution. These results indicated that the polymers can be applied in the recovery of Ag(I).

Published: October 2023

This article is devoted to solving the problem of interaction of theoretical knowledge obtained and solving technical problems when students receive higher education within the framework of studying the discipline of higher mathematics. Teaching higher mathematics should give students not only a theoretical foundation, but it is also important to focus on the acquisition of practical skills necessary in the future professional activity of a future specialist. We propose to consider the connection of theoretical knowledge and practical skills of future specialists not as a transition from assimilation of information to application in practice, but as integration through the categories of unity, integrity of the system. In addition, students develop at a higher level the skills to systematize knowledge, establish a link between new and previously acquired knowledge. At the same time, it is often necessary to establish more precisely the boundaries in which it is possible to apply certain mathematical methods. As experience shows, an effective method of interrelation of theory and practice was the introduction of professionally-oriented tasks into the teaching process of the discipline of mathematics. The authors of the article propose to consider professionally-directed tasks in practical classes in higher mathematics.As an example, the tasks for the specialties 23.05.03"Rolling stock of railways" and 23.05.04 "Operation of railways" are given.

Authors:   Samara State Technical University, Zhuravlev A.P.
Published: October 2023

This paper analyzes the translation of the short story called “The Repairer of Reputations” by Robert W. Chambers into Russian (two variants of translation are considered). The paper provides the analyses of various aspects that determine the quality of translation, particularly the ability to work with terminology, proper approach to translation of nonequivalent lexis, sensible application of lexical and grammatical transformations. The comparative analysis of the two translations of the story revealed a number of differences between them. In each of these cases the advantages and disadvantages of a particular variant of translation are considered to figure out which one of them is more adequate to the context of the story. The results of the research are used to draw a conclusion about professional knowledge and skills a translator needs to make a good translation of a literary work. The paper also points out the importance of written translation (as well as the analysis of a translation made by someone else) as some kind of students’ individual work that helps them master the foreign language they learn.
METHODS OF INCREASING MOTIVATION FOR CHOREOGRAPHY LESSONS IN STUDENTS OF HIGHER EDUCATION INSTITUTIONS OF CULTURE
Authors:   Samara State Institute of Culture, Pavinskaya K.V.
Published: October 2023

This article touches upon the problem of motivation for the activities of students-choreographers of universities of culture and art, without which the most effective pedagogical methods and technologies do not bring the desired result. The problem is relevant for the system of higher choreographic education. The paper considers the methods of stimulating motivation for activity, which, in the author's opinion, bring the greatest benefit in the formation of motivation for choreographic activity. The revealed methods are tested during the ascertaining and forming experiment in the system of higher education of choreographers. The author gives statistical data of the changes that have taken place with the motivation of choreographer students to work, after the introduction of a set of selected methods for stimulating motivation. Analysis of the data shows that during the experiment the number of students with a positive motive for activity in the second and third year of the Samara State Institute of Culture increased significantly and the number of students with a negative motive for activity decreased (from 53% to 0%) and (from 66% to 0 %). For first-year students, the changes are not statically significant, due to the fact that a positive motive for activity was observed among choreographer students in the first year of study and amounted to (89%). This led to the conclusion that the primary task of a teacher of a modern university will be to promote the emergence of positive motives for activity, before introducing new methods and technologies for teaching students.
ONTOLOGY OF SIXTY-YEAR CYCLES: ON THE EXAMPLE OF RUSSIAN HISTORY
Authors:   Samara State Transport University, Denisov D.V.
Published: October 2023

The author considers the possibility of assigning to five 12 years of the 60-year Chinese cycle of functions that are steadily implemented over several cycles. He proposes a method of ontological modeling, within the framework of which the most general structural diagrams, both modern and ancient, are regarded as functional diagrams. In the course of the analysis, an ontological substantiation of five 12-year periods is proposed. Не analyzes the most famous five-element models of antiquity and modernity, on the basis of which the ontological structure of this cycle and the functions implemented by each of the 12-year periods become clear. Approbation of the obtained universal model of development is carried out on the material of four 60-year cycles of Russian and world history. The analysis showed that some trends are regularly repeated in Russian history, some trends are more significant for Western ones. The result obtained demonstrates that all the listed 5-element models from mythological and philosophical to political, socio-economic, as well as natural sciences occupy a full-fledged place in the modern scientific paradigm

Background. In a novel coronavirus pandemic, the most common complications of viral pneumonia are secondary infections of bacterial and fungal etiology. At the same time, the spread of multidrug-resistant bacteria remains a global threat to public health. One of such microorganisms of the Enterobacteriaceae family is Klebsiella pneumoniae, which belongs to dangerous resistant pathogens of the ESKAPE group.

The aim of the study was the comparative analysis of the biological properties of classical and hypermucoid strains of K.pneumoniae isolated from patients with community-acquired pneumonia (CAP): characterization of their sensitivity to antibacterial drugs, Klebsiella bacteriophage, and a disinfectant (polyhexamethylene guanidine hydrochloride), as well as assessment of the strains’ virulence in the model of experimental infection in white mice.

Material and methods. 56 strains of Klebsiella isolated in diagnostic quantities from patients’ sputum samples were studied. Species identification of cultures was carried out using bacteriological and mass spectrometric methods. The sensitivity of bacteria to antibiotics, bacteriophage, and the disinfectant was determined in accordance with regulatory documents.

Results. In the course of the study, 243 gram-negative cultures were isolated, of which 30% were bacteria of the genus Klebsiella spp. An analysis of their species composition showed that K.pneumoniae occupied a dominant place in the structure. Based on colony morphology, Burri-Gins smear staining, and a positive string test, 14 strains with a hypermucoid phenotype were identified. These strains differed from the classic K.pneumoniae strain by the presence of a thicker capsule in smears, virulence in white mice (DCL≤103 mc), and increased resistance to commercial Klebsiella bacteriophage. At the same time, they were characterized by a wider spectrum of sensitivity to antibiotics. There were no significant differences in sensitivity to the disinfectant in strains of both morphotypes.

Conclusion. The results obtained demonstrated the important role of K.pneumoniae in the etiological structure of CAP pathogens.

An Experimental Study to Analyze the Efficacy of Backwards Gait Training on Balance and Weight Bearing Asymmetry on Sub-Acute Stroke Patient
Authors: Arpita Chatterjee  , Rajendra Kachhwaha
Published: October 2023

Background: Stroke is the leading cause of long-term disability and death, and the second leading cause of deathworldwide. The first month after a stroke is a vital period since the brain goes through major plastic changes duringthis time. Motor learning studies emphasize the significance of experience and learning in functional rehabilitation.Because training is a potent stimulator of neuroplasticity, the addition of a focused rehabilitation strategy canimprove recovery by maximizing brain reconfiguration. Backward Walking Training (BWT) is an adjuvanttherapeutic and rehabilitation method to improve proprioception, muscle strength, intra-limb coordination, andbalance. Studies examining its effects on balance and weight bearing asymmetry are lacking.Objective: To determine the effect of BWT on balance and weight bearing asymmetry in sub acute stroke subjects.Results: The difference between the pre- and post-test results within the group for balance on Berg Balance Scale(BBS) as well as the weight on the affected and unaffected Lower Limb (LL) on the Body Weighing Machine(BWM) are both deemed to be significant for paired T-Test. According to conventional standards, when comparingpre- and post-test results for balance and the difference in weight between the two groups for the affected andunaffected Lower Limb (LL) on the BWM for the experimental and control groups using Unpaired T-Test, it canbe inferred that the difference is statistically significant.Conclusions: When combined with conventional physiotherapy as opposed to conventional physiotherapyalone, backwards gait training has a modestly greater impact on balance and weight bearing asymmetry. Bergbalance score and weight bearing asymmetry can both be improved in stroke patients using BWT as an additionto standard care (moderate evidence).

Published: October 2023

The veil, or hijab, is one of the teachings of Islam intended for Muslim women. The law on wearing the veil for Muslim women is debated by scholars; some make it mandatory; it is sunnah; and there are scholars who determine the law is permissible. This research aims to review the legal issue of wearing the veil from the perspective of Islamic legal philosophy. This type of research is library research using a qualitative approach. Data collection was carried out by reading research sources in the form of books, journals, and relevant readings, which were then analyzed using descriptive techniques. This research found that wearing a veil for a woman produces maslahah at the tahsiniyah level because the woman will be more protected, both from the evil side of other people and in terms of protecting her face from things that disturb her beauty. Therefore, philosophically, the law of wearing the veil is at the level of sunnat (recommended).

The study focused on the moderating role of gender on the relationship between emotional intelligence and hotel employee work behaviour. To achieve the objective of the study, survey research design was adopted. Self-awareness and self-control were used to measure emotional intelligence which represents the independent variable while employee behaviour was used as the dependent variable. The researcher adopted primary data in getting the required information through the use of structured questionnaire. The population of the study is made up of 431 male and female hotel staff. The sample size of the study is 274 after adopting Taro Yamane formula. In analysis the data, moderated regression analysis was used. The findings revealed that self-awareness and self-control have significant influence on employee work behaviour. The findings also showed that gender moderates the relationship between emotional intelligence and employee work behaviour in hotels. Based on the findings, the study recommends that Management should look for an organizational wide approach of bringing the employees closer to each other like organizing get together activities, end of the year parties and other social events so that they can understand themselves better as this will go a long way in increasing their awareness of others and relate well with others. While recruiting, emphasis should not be placed on IQ alone; effort should also be made to ascertain the Emotional Intelligence level of these employees for industrial harmony.

Published: October 2023

Aim: We therefore wanted to investigate acetaminophen hepatotoxicity by using Hep3B human hepatoma cells exposed to acetaminophen and resveratrol, used as a protective agent. Specifically, we studied the role of some proinflammatory markers and oxidative damage as possible mechanisms of acetaminophen-associated cytotoxicity.

Materials and Method: The Hep3B human hepatoma cell line was used for this study. In vitro studies (GSH, SOD, CAT, AST, ALT, TNF-alpha, IL-6 and cell viability) were performed by using different methods such as Biochemical analyzer, RT-PCR, ELISA and MTT. Acetaminophen and resveratrol were applied to cells in a different time and doses.

Results: Only acetaminophen treatment decreased SOD, CAT and GSH levels in Hep3B cells whereas acetaminophen and resveratrol co-treatment increased these enzymes levels. On the other hand, acetaminophen and resveratrol co-treatment (especially 160 µM dose of resveratrol) lead a severe increase in TNF-alpha and IL-6 levels.

Conclusion: It is shown that acetaminophen has caused hepatotoxicity but interestingly but resveratrol treatment effects the related parameters mentioned above. Only, acetaminophen administration may cause abnormal decreases and/or increases in antioxidant enzymes and proinflammatory cytokines levels. Additionally, acetaminophen and high dose resveratrol co-treatment triggered the inflammation and oxidative stress. These results showed that resveratrol have a potential to be an effective agent on the treatment and protection of hepatic damage.

The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence of technologically advanced extraterrestrial life. Radio signals similar to those engineered on Earth may be transmitted by other civilizations, motivating technosignature searches across the entire radio spectrum. In this endeavor, the low-frequency radio band has remained largely unexplored; with prior radio searches primarily above 1 GHz. In this survey at 110–190 MHz, observations of 1,631,198 targets from TESS and Gaia are reported. Observations took place simultaneously with two international stations (noninterferometric) of the Low Frequency Array in Ireland and Sweden. We can reject the presence of any Doppler drifting narrowband transmissions in the barycentric frame of reference, with equivalent isotropic radiated power of 1017 W, for 0.4 million (or 1.3 million) stellar systems at 110 (or 190) MHz. This work demonstrates the effectiveness of using multisite simultaneous observations for rejecting anthropogenic signals in the search for technosignatures.

We describe IXPE polarization observations of the pulsar wind nebula (PWN) MSH 15−52, the “Cosmic Hand.” We find X-ray polarization across the PWN, with B-field vectors generally aligned with filamentary X-ray structures. High-significance polarization is seen in arcs surrounding the pulsar and toward the end of the “jet,” with polarization degree PD > 70%, thus approaching the maximum allowed synchrotron value. In contrast, the base of the jet has lower polarization, indicating a complex magnetic field at significant angle to the jet axis. We also detect significant polarization from PSR B1509−58 itself. Although only the central pulse phase bin of the pulse has high individual significance, flanking bins provide lower-significance detections and, in conjunction with the X-ray image and radio polarization, can be used to constrain rotating vector model solutions for the pulsar geometry.

The Nancy Grace Roman Space Telescope (Roman) is NASA’s next astrophysics flagship mission, expected to launch in late 2026. As one of Roman’s core community science surveys, the Galactic Bulge Time Domain Survey (GBTDS) will collect photometric and astrometric data for over 100 million stars in the Galactic bulge in order to search for microlensing planets. To assess the potential with which Roman can detect exoplanets via transit, we developed and conducted pixel-level simulations of transiting planets in the GBTDS. From these simulations, we predict that Roman will find between ∼60,000 and ∼200,000 transiting planets—over an order of magnitude more planets than are currently known. While the majority of these planets will be giants (R

p
> 4R
⊕) on close-in orbits (a < 0.3 au), the yield also includes between ∼7000 and ∼12,000 small planets (R

p
< 4R
⊕). The yield for small planets depends sensitively on the observing cadence and season duration, with variations on the order of ∼10%–20% for modest changes in either parameter, but is generally insensitive to the trade between surveyed area and cadence given constant slew/settle times. These predictions depend sensitively on the Milky Way’s metallicity distribution function, highlighting an opportunity to significantly advance our understanding of exoplanet demographics, in particular across stellar populations and Galactic environments.

The genus Diaporthe (Diaporthaceae, Diaporthales) is a large group of fungi frequently reported as phytopathogens, with ubiquitous distribution across the globe. Diaporthe have traditionally been characterized by the morphology of their ana- and teleomorphic state, revealing a high degree of heterogeneity as soon as DNA sequencing was utilized across the different members of the group. Their relevance for biotechnology and agriculture attracts the attention of taxonomists and natural product chemists alike in context of plant protection and exploitation for their potential to produce bioactive secondary metabolites. While more than 1000 species are described to date, Africa, as a natural habitat, has so far been under-sampled. Several endophytic fungi belonging to Diaporthe were isolated from different plant hosts in Cameroon over the course of this study. Phylogenetic analyses based on DNA sequence data of the internal transcribed spacer region and intervening 5.8S nrRNA gene, and partial fragments of the calmodulin, beta-tubulin, histone and the translation elongation factor 1-α genes, demonstrated that these isolates represent four new species, i.e. D. brideliae, D. cameroonensis, D. pseudoanacardii and D. rauvolfiae. Moreover, the description of D. isoberliniae is here emended, now incorporating the morphology of beta and gamma conidia produced by two of our endophytic isolates, which had never been documented in previous records. Moreover, the paraphyletic nature of the genus is discussed and suggestions are made for future revision of the genus.
Traversée du genre, traversée du fantasme
Authors: Hefez Serge
Published: October 2023

La sexualité reste un terrain peu exploré des études sur la transidentité. Si sexe et genre recouvrent des données hétérogènes, il est difficile de ne pas entendre des questionnements qui s’entremêlent. L’auteur s’appuie sur ce que des jeunes en transition, en fluidité de genre, ou qui souhaitent échapper aux catégories homme/femme, homo/hétero, cis/trans disent de leurs pratiques sexuelles. Comment intervient la puissance d’agir de ces corps en transformation dans l’élaboration de nos théories ?

Published: October 2023

Cet article explore la problématique de l’effacement de soi à l’adolescence et ses enjeux au regard du processus d’appropriation subjective à partir d’un cadre-dispositif original centré sur le « récit dessiné ». Le travail clinique engagé auprès d’une jeune adolescente aux prises avec une souffrance narcissique-identitaire nous conduit à repérer comment l’effacement de soi participe à la réorganisation des capacités réflexives et au rétablissement des conditions de subjectivation en appui sur la fonction miroir du médium et du thérapeute.

À partir d’une clinique auprès d’adolescents en maison d’enfants à caractère social (MECS) qui confronte à la non-demande en même temps qu’à une modalité de lien aux prises avec la séduction narcissique, l’incestuel et la toute-puissance, nous interrogeons les modalités du dispositif qui permettraient d’engager un processus thérapeutique. À cet effet, nous proposons de définir le dispositif « en triple résonance » et d’illustrer, à partir de la situation d’un adolescent de quinze ans, ses potentiels effets et leviers.
Effect of Graphene Nanoplatelets on Flexural Behavior of Glass Fiber Reinforced Polymer Composites Subjected to Different Temperatures
Authors: Tudu Suplal , Velmurugan Ramachandran
Published: October 2023

Glass Fiber Reinforced Polymer (GFRP) Composite are increasing rapidly in Aerospace Industry, Civil and Wind energy sectors, where they can frequently be exposed to different temperature conditions. As the constituent polymer matrix is highly affected by temperature, extreme temperature conditions are critical for GFRP composite structural design. Researchers have recently found nanofillers such as graphene and carbon nanotubes with excellent multifunctional mechanical properties. Graphene Nanoplatelets (GnP) consist of several layers of graphene. GnP is considering an attractive nanofillers as it has improved polymer matrix properties. In this study, the weight percentage of GnP added in GnP-GFRP laminate is 0.25% and 0.5%.GFRP and GnP-GFRP laminates are fabricated by using the hand lay-up method, and the specimens are subjected to a three-point bending test in a thermal chamber with varying the temperature, i.e., 30°C, 50°C, 75°C, and 100°C. This paper investigates the effect of graphene nanoplatelets on the flexural behavior of glass fiber-reinforced polymer composites subjected to different temperatures. Flexural strength and modulus are evaluated, and the appropriate conclusions are determined. GFRP with 0.25% GnP shows higher strength than the neat and 0.5% GnP-GFRP. Here, it has also been shown that flexural strength and modulus decrease significantly with increasing temperature.

To investigate the behaviour of oxidation and chromium volatilisation, AISI 430 stainless steel was oxidised in O2-H2O and Ar-CO2-H2O atmospheres for 96 h at 800°C with varying water vapour content. In the O2-H2O environment, the volatilisation rate of Cr and Mn increased as the water vapour content increased from 5% to 20%. In the case of Ar-CO2-H2O conditions, the presence of water vapour in the Ar-20%CO2 environment reduced the oxidation rates of the steel. However, increasing the H2O content in Ar-20%CO2 had an insignificant effect on the oxidation rate. Water vapour was found to accelerate the volatilisation rate of Cr and Mn. Breakaway oxidation occurred in Ar-20%CO2-40%H2O, resulting in the highest volatilisation rates of Cr and Mn.

Several degenerative diseases, including cancer, are caused by oxidative stress, which is caused by the overproduction and accumulation of free radicals. The purpose of the study was to synthesize gallic acid (GA or 3,4,5-trihydroxybenzoic acid) esters and evaluate their anti-inflammatory potential through the inhibition of reactive oxygen species (ROS). The compounds methyl gallate (2), sec-butyl gallate (3), ethyl gallate (4), isopropyl gallate (5), 2-methoxyethyl gallate (6), 4-methoxybutyl gallate (7), 2-methylbutyl gallate (8) and pentan-3-yl gallate (9) were synthesized. 1H NMR, MS and IR data are reported for compounds 2-9, and 13C NMR data for compounds 2, 3, 5, and 6. The molecular formulae of compounds 3 and 7-9 were established by HREI-MS spectroscopic data. All the synthesized compounds were tested for their anti-inflammatory and cytotoxic activities by chemiluminescence and MTT cytotoxicity assay respectively. The results revealed the anti-inflammatory potential of compounds 2-8 with an IC50 range between (13.3 – 54.3 µM) as compared to the standard anti-inflammatory drug, Ibuprofen (IC50 = 54.3 ± 9.2 μM). The most potent inhibitors were found to be compound 3 (ROS IC50 = 15.0 ± 6.6 µM) and compound 7 (ROS IC50 = 13.3 ± 0.8 µM). All compounds were found to be non-cytotoxic in the NIH-3T3 fibroblast cell line. Compounds 3, 7- 9 were identified as new compounds.

Published: October 2023

Fossil whip scorpions (Thelyphonida) are extremely rare in the Crato Formation strata, Araripe Basin, Lower Cretaceous (Aptian) of Brazil. Only four specimens of whip scorpions have been described in this unit so far. All specimens have been assigned to the genus Mesoproctus Dunlop and only one species has been formally proposed, M. rowlandi Dunlop. For Mesozoic times, apart from Crato Formation, whip scorpions are only documented by two species in the amber deposits of the Hukawng Valley, northern Myanmar. In this scenario, each new discovery of Mesozoic whip scorpion is highly important. In addition, we present the first documented example of book lungs from a fossil whip scorpion. Here, we present and illustrate a new specimen of whip scorpion found in the Crato strata. Keywords: Crato arachnofauna, Uropypi, Mesoproctus, Aptian, Lagerstätten.

ABSTRACT

Background:

Despite being uncommon, pilon fractures are of interest to orthopedic surgeons because of the awkwardness of their treatment. Although various surgical techniques were used, poor outcomes are frequently encountered, and complications are highly prevalent.

Objective:

The objective of this study was to evaluate the clinical and radiographic outcomes of pilon fractures treated with a two-stage technique.

Materials and Methods:

The study included patients with tibial pilon fractures who had undergone two-stage procedures in King Saud Medical City (April 2017–March 2022). Fractures were categorized based on the Arbeitsgemeinschaftfur Osteosynthesefragen (AO) classification method. Outcomes were measured by the American Orthopedic Foot and Ankle Society (AOFAS) scoring system.

Results:

Twenty-one patients had tibial pilon fracture. Open fractures were seen in 23.8%, the majority was Gustilo type II in 60%. The mean follow-up was 24.7 months. The majority (47.6%) was AO type 43-B. Osteoarthritis was developed in 61.9%, and none mandates arthrodesis. Mean AOFAS was 86.91 points, it was excellent in 38.1%. Type 43 C fracture significantly had a poorer AOFAS score (P = 0.021). AOFAS score was significantly affected by fracture grade and association with fibular fracture, P = 0.025, and P = 0.019, respectively.

Conclusion:

Treatment for severe pilon fractures with a two-stage protocol yields favorable outcomes. Fewer soft-tissue complications and better articular reconstruction were the main benefits.
