Iridium Catalyzed Enantioselective C3 Allenylation of Pyridines
Authors: Roy Pankaj , Mahto Pratibha , Mukherjee Santanu
Published: December 2024

An enantioselective C3-allenylation of pyridines has been developed through the intermediacy of oxazino pyridines. This dearomatization/electrophilic substitution/rearomatization strategy leverages the nucleophilicity of oxazino pyridines, whose enamine/dienamine-like reactivity is combined with iridium-activated allenylic carbocations to achieve a formal C3-allenylation of pyridines. Using racemic allenylic alcohols as the allenylic electrophile, this reaction is catalyzed by an Ir(I)/(P,olefin) complex, and delivers a wide range of C3-allenylic pyridines in moderate to good yields with excellent level of enantioselectivity (up to >99.9:0.1 er). The modularity of this approach allows for not only subsequent electrophilic chlorination but also the deadenylation of pyridines. The latter reaction allows access to all possible stereoisomers of 3,5-diallenylic pyridines with excellent diastereo- and enantioselectivity in a three-step, two-pot process. This is the first example of an enantioselective transformation of oxazino pyridines en route to chiral C3-functionalized pyridines.
Balancing Reactant Adsorption for Ultra-Stable Electrocatalytic Methanol Oxidation Reaction
Authors: Liu Yang , Wu Ruyan , Jin Yongzhen , Dong Jiaye , Li Hongju , Wang Jianhui
Published: December 2024

The practical application of the electrocatalytic methanol oxidation reaction (EMOR) has long been hindered by the lack of active and stable catalysts. Herein, we report a unique dealloyed PtMn catalyst on carbon cloth (d-PtMn/CC) characterized by a compressively strained Pt surface and a Mn concentration-gradient core. This d-PtMn/CC catalyst demonstrates EMOR activity that is 7–14 times higher than that of conventional Pt/CC catalysts in all-pH electrolytes, while exhibiting exceptional resistance to catalytic poisoning over a broad potential range of 0.4 to 1.2 V vs. RHE. When employed in direct methanol fuel cells, it achieves 111.6 mW cm−2 for over 10 hours at ultralow 0.59 mgPt cm−2, substantially outperforming commercial Pt/C catalysts. Comparative analyses of adsorbed reactants/intermediates revealed that imbalanced adsorption of reactants on the catalyst surface is the primary cause of EMOR poisoning. The d-PtMn/CC catalyst, benefiting from surface compressive strain and ligand effects, maintains balanced reactant adsorption over the wide potential range, thereby achieving ultra-stable EMOR performance. These findings not only resolve the longstanding controversy regarding EMOR poisoning mechanism but also identify the effectiveness of the “ligand + surface strain” strategy in DMFCs, facilitating its practical applications.
The Role of Counterion Size in Defining Star-Shaped Polyelectrolytes Thermodynamics, Conformations, and Ion Dynamics
Authors: Tagliabue Andrea , Mella Massimo
Published: December 2024

In this work, we systematically investigate the impact of counterion size on the behavior of star-shaped strong polyelectrolytes in dilute aqueous solutions using Langevin simulations and a primitive model of electrolytes. Varying both the counterion diameter and the number of arms of the polyelectrolyte, we demonstrated that both characteristics significantly impact polyelectrolyte conformations and counterions absorption. Counterions dynamics is also affected, the most interesting aspect being the presence of a fraction of mobile ions slowly diffusing, compared to the average behavior, which increases with polyelectrolyte branching and their size. Informed by the results on systems with single-size counterions, we also investigate possible changes in behavior of these polyelectrolytes when neutralized by a binary mixture of bulky and small counterions at different relative concentration. Our results show that small counterions demonstrate a greater tendency for remaining located within the inner regions of the polyelectrolyte, particularly when their molar fraction is low and the polyelectrolyte is highly branched. This results in the spatial separation of the two species into core-shell-like structures, which dramatically decreases the diffusivity of the smaller counterions. By investigating the partitioning of counterions between the solution and the regions internal to the polyelectrolytes, it is shown that the selectivity toward the smaller species can be significantly enhanced by increasing the number of arms and operating under conditions of counterion scarcity.

Published: December 2024

Solar-driven plasmonic photocatalysis has emerged as a powerful tool to enhance chemical reactivity, improving the efficiency and selectivity in a large number of transformations. Plasmonic nanoparticles are often implemented in photocatalysis as colloidal dispersions but they face issues related to the reduced photoactivation of the metallic surface in concentrated solutions and poor long-term colloidal stability. To overcome these limitations, we introduce 3D plasmonic supercrystals created through the depletion- and evaporation-induced self-assembly of metal nanoparticles as novel heterogeneous plasmonic photocatalysts. They present large electromagnetic field enhancements associated to the formation of regular arrays of plasmonic hot spots, leading to improved chemical reactivities through the generation of hot charge carriers. To demonstrate this, we chose two challenging organic transformations, an oxidative polymerization and different C‒C cross-coupling reactions, that can be activated by modifying the chemical composition of the assemblies. Interestingly, the anisotropic shapes of the building blocks lead to the formation of 3D supercrystals exposing different crystalline facets. Importantly, by performing operando Surface-Enhanced Raman Spectroscopy at the single supercrystal level, we unveil the face-dependent reactivity of each individual plasmonic superstructure. Our combined experimental and theoretical approach provides with key insights into structure-function correlations and offers guidelines for the rational design of versatile supercrystal photocatalysts.
Understanding the Nitrogen Reduction Reaction Mechanism on CuFeO2 Photocathodes
Authors: Beßner Julian , Jacob Timo
Published: December 2024

This study investigates the reaction pathways for the conversion of \ce{N2} to \ce{NH3} on \ce{CuFeO2} (CFO) by employing density functional theory (DFT) calculations. Concentrating on the most stable (012) surface orientation, two systems were examined: the pristine (012) surface and the corresponding oxygen defective surface. To find the thermodynamic stable pathway, the associative Heyrovsk{\'y} mechanism was considered, containing four different reaction pathways. The reaction intermediates predominantly interact with the iron sites on the surface, following the distal alternating reaction pathway via the formation of hydrazine. Introducing oxygen defects changes the reaction mechanism to a Mars--van--Krevelen--type mechanism, avoiding the formation of hydrazine, while the Gibbs free energy of the first hydrogenation step is lowered by 1.17~eV (from 2.17 to 1.00~eV). Analyzing the charge density distribution reveals that oxygen defective surface enables CFO to facilitate a $\pi$--backdonation between iron sites and the NRR intermediates, increasing the intermediate--surface interaction. This indicates an enhanced catalytic activity for the NRR by generating oxygen lattice defects in CFO.

De l’espace intime du harem à la pratique de l’esclavage : mythes et réalités dans les récits des voyageuses françaises
Authors: Sanchez Diosdado Juan Manuel
Published: December 2024

Aline de Lens, Henriette Célarié et Mathilde Zeys observent les femmes esclaves qui habitent à l’intérieur du harem marocain pour dévoiler au lecteur métropolitain un univers qui leur semble fantasmagorique. Parfois, ces voyageuses s’éloignent de la représentation bigarrée de stéréotypes orientalistes pour s’approcher de la pratique réelle de l’esclavage qui perdure en dépit de son abolition par les autorités coloniales en 1912. Elles présentent ainsi deux visions sur l’esclavage qui semblent antagoniques mais qui sont susceptibles de transmettre une vision plus globale sur la réalité des femmes esclaves et sur les diverses façons de les représenter dans la veine de l’orientalisme.
Entre fictions autobiographiques et réelles biographies : la mémoire de Tanger selon Elisa Chimenti (1883-1969), une voyageuse atypique
Authors: El Ghaoui Lisa
Published: December 2024

Première voix féminine de littérature maghrébine d’expression française, Elisa Chimenti (Naples 1883 – Tanger 1969), autrice polyvalente (enseignante, ethnologue, journaliste, écrivaine), a posé un regard rare sur la condition des femmes, les rapports entre Orient et Occident, l’histoire des mythes et légendes et la richesse du patrimoine immatériel marocain. Tangéroise d’adoption, elle a consacré sa vie à la sauvegarde et à la diffusion de ce patrimoine fragile afin de le faire connaître au-delà des préjugés et des frontières. Le roman inédit « Petits Blancs marocains » (1940-1960), à la fois récit historique, de voyage et de formation, illustre de quelle manière Chimenti s’émancipe des modèles de récit viatique au féminin, tout en les revisitant, dans une double autobiographie fictionnelle, où s’entremêlent voyages physiques dans la ville de Tanger et ses alentours et voyages mémoriels en lien avec un groupe d’exilés européens, appelés « Petits Blancs », invisibles ou oubliés, auxquels elle rend hommage à travers une série de portraits.

A revolutionary temporary immersion bioreactor method for commercialscale Musa sp. (Tanduk and Berangan) multiplication
Authors: Khirul Anuar N.A. , Ahmad Usuldin S.R. , Md Saad N.
Published: December 2024

Large-scale clonal banana production is required to supply current industry demand.
Conventional tissue culture technique needs to be improvised to overcome the high-cost
manufacturing and laborious work involved. Therefore, this study aimed to develop an
efficient protocol in clonal banana production by using temporary immersion bioreactor
(TIB) technology which uses intermittent immersion in liquid nutrients. This study
evaluated the optimum protocol pathway for efficient Musa acuminata cv. Berangan and
Musa paradisiaca cv. Tanduk propagation with the application of TIB system. M.
acuminata and M. paradisiaca optimum initiation medium were developed in MS
(Murashige and Skoog) media supplemented with 3 mg/L 6-Benzylaminopurine (BAP)
and 0.2 mg/L Thiamine and 0.3 mg/L Thidiazuron (TDZ) respectively. The optimum
proliferation medium in TIB developed in MS media supplemented with 3 mg/L BAP for
both varieties. The highest number of shoots was achieved in TIB with 20 initial plantlets
and a 15-minute immersion with a 6-hour gap along with a 14-day incubation period.
Micropropagation of Musa sp. in Temporary Immersion Bioreactor System (RITA ®) has
successfully shown significant growth as compared to MS media agar-conventional
technique with reduced phenolic content released in both varieties. In conclusion, the
production of Musa acuminata cv Berangan and Musa paradisiaca cv. Tanduk by using a
temporary immersion bioreactor (TIB) system has huge potential to improve the scale
production output with lower-cost plantlets

Published: December 2024

Individual ultrasound treatment or adding exogenous enzyme treatment such as papain has
been successfully proven to not only marinate but tenderise the meat. Incorporating both
treatments at the same time could further tenderise the meat but the quality of the meat
might be compromised. Hence, this study aimed to investigate the effect of ultrasound
treatment coupled with papain solution on the quality properties of meat. Four different
treatments were carried out on the meat samples; control (C), papain treated (P),
ultrasound treated (US), and a combination of papain and ultrasound treated (USP). Meat
treated with USP did not affect the physicochemical properties of the meat as no
significant difference was found in water holding capacity (WHC), cooking loss and pH.
Moreover, USP treatment was found to have effects on textural properties of the meat
samples as positive linear relationships between the hardness of the treated meat with
work of shear were found via Pearson correlation analysis. This is in line with the findings
on the microstructure of the treated meat samples where tenderised meat samples
exhibited disrupted muscle fibre. Thus, incorporating papain and ultrasound together
improved the quality texture of the meat.
The comprehensive analysis of pro-environmental food purchasing behaviour
among consumers observing halal diet

Published: December 2024

This study aimed to analyse the purchasing behaviour of pro-environmental food products
among halal-diet consumers by adapting the Theory of Planned Behaviour as a research
model. A quantitative method approach involved an online questionnaire administered to
Malaysian consumers in Klang Valley to assess their norms, social norms, consumer
sustainability orientation and perceived availability towards pro-environmental food
consumption. Using structural equation modelling (SEM) in AMOS21, the findings reveal
significant (p-value < 0.001) correlations between the Theory of Planned Behaviour
constructs towards the environmentally conscious purchase behaviour among halal-dietary
consumers. Personal norms, social norms, consumer sustainability orientation and
perceived availability significantly influence consumers' environmentally conscious
purchases. Therefore, this study contributed to a deeper understanding of proenvironmental food consumption among behaviour halal-dietary observers in Malaysia.
Theoretically, there are strong relationships on the pro-environmental behaviour among
halal-dietary observers. This study contributed to the existing literature by offering a
comprehensive analysis of halal food consumption behaviours among Malaysians,
employing quantitative methods within the Theory of Planned Behaviour framework. By
examining the interplay between personal norms, social norms, consumer sustainability
orientation and perceived availability, this study provided a nuanced understanding of
halal food consumption dynamics in the Malaysian context, filling a gap in the literature
and offering valuable insights for future research and practical applications. The findings
had implications for industry and managers involved in the halal food industry, guiding
targeted marketing strategies, product development, and policy initiatives to promote halal
food consumption.
Micropropagation of coconut (Cocos nucifera Linn var. pandan) through
somatic embryogenesis technique
Authors: Maslini J.A. , Intan N.H.A.H.
Published: December 2024

Coconut, also known as Cocos nucifera, is one of the most recalcitrant species for in vitro
regeneration. Conventional coconut breeding has a long lifetime and high heterozygosity,
making it a time-consuming, intricate, and costly technique for plant growth. As a result, it
is critical to replant most of the world's agricultural land and to develop new soil. This
massive undertaking will necessitate planting at least a billion coconut palm trees, which
cannot be propagated by seed. Somatic embryogenesis, as a biotechnological alternative,
is thus required. Work on this subject has been done in laboratories in numerous countries,
with different techniques and explant shapes being investigated. The zygotic embryos are
more effective in initiating the callus induction fortified on C1 and C2 formulations added
with activated charcoal, gelling agent, and hormone 2, 4- dichlorophenoxyacetic acid (2,4-
D). The study has observed that the C1 media successfully initiated callus formation, but
the C2 media allowed embryogenic calluses and somatic embryos to develop. From this
study, the seedling and regenerated callus were growing well on C3 media. Mature
coconut plantlets were acclimated using a combination of sphagnum, sand, and soil mix.
The plantlets, on the other hand, could not adapt to their circumstances.
Effect of soaking and high-pressure processing on antioxidant content,

(L.) Verdc) flour
Authors: Omoniyi S.A. , Mustapha N.A. , Shukri R. , Ramli N.S. , Sulaiman R.
Published: December 2024

The study evaluated the effect of pre-treatment methods on the antioxidant content,
functional properties and pasting profile of Bambara groundnut flour. Soaking and highpressure processing (HPP) were used as pre-treatment methods. The results revealed that
the value of crude protein, crude fat, total phenolic compounds, 2,2-Diphenyl-1-
picrylhydrazyl, ferric reducing antioxidant power, dispersibility, water absorption index
and swelling capacity of HPP pre-treated Bambara groundnut flour were significantly
higher than the values obtained for raw and soaked pre-treated Bambara groundnut flour.
The application of HPP pre-treatment to Bambara groundnut flour resulted in notable
improvements in dispersibility, water absorption index, and swelling power. The pasting
curve revealed increased peak viscosities in both soaked and HPP pre-treated samples,
particularly highlighting the potential for products requiring enhanced gel strength.
Additionally, the HPP pre-treated flour exhibited the shortest peak time, suggesting faster
cooking and underscoring its versatility in various applications.

Published: December 2024

The perishability and susceptibility to chilling of Carica papaya Linn have impeded its
long-distance exportation, posing challenges to international trade investments. This study
explores the efficacy of 1-MCP and geranium oil (GO) treatments in enhancing papaya's
cold tolerance. Designated concentrations for 1-MCP were 300 and 600 mg/L, and for
GO, 2% and 4% (v/v), with exposure times set at 30 and 60 mins. Subsequently, the fruits
were stored at 4°C for 16 days, and various parameters such as chilling injury (CI), weight
loss (WL), respiratory rate (RR), firmness, colour, total soluble solids (TSS), titratable
acidity (TA), pH, and ripening index (RI) were assessed at 4-day intervals. The results
demonstrated a significant reduction in chilling damage in treated fruits. Specifically, the
60-minute exposure to 600 mg/L 1-MCP (MCP600+60) delayed the development of CI
symptoms by at least 4 days compared to the control. At day 16, MCP600+60 exhibited
the least WL (1.93%), O2 consumption (4.19±0.25 mL/kg/hr), and CO2 production
(4.05±0.17 mL/kg/hr). Treated fruits, especially MCP600+60 and 30-minute exposure to
4% (v/v) GO (GO4+30), preserved firmness and colour. In GO treatments, GO4+30
showed the least increase in TSS (1.69-fold) and pH (1.09-fold). The highest TA and RI
were reported in MCP600+60 and GO4+30. Overall, MCP600+60 emerged as the most
effective treatment for enhancing papaya's cold tolerance and storage quality based on our
study.

Authors: Li Zifeng , He Li
Published: December 2024

Objective: To explore the effect of applying the Plan-Do-Check-Act (PDCA) cycle combined with instrument mapping to manage surgical instruments in a hospital sterilization supply center. Methods: A total of 600 surgical instruments in a hospital’s surgical instrument sterilization and supply management center were sampled and grouped based on the introduction of the PDCA cycle combined with instrument mapping. The control group included 300 surgical instruments subject to routine sterilization management from November 2023 to January 2024. The observation group included 300 surgical instruments managed with the PDCA cycle combined with instrument mapping from February 2024 to April 2024. The quality of surgical instrument management, incidence of adverse events, and other indicators were compared between the two groups. Results: The observation group demonstrated significantly higher scores in management quality indices compared to the control group, with scores for disassembly and assembly (93.28 ± 1.57 vs. 87.41 ± 1.48), cleaning (95.04 ± 2.08 vs. 90.23 ± 2.12), disinfection and sterilization (95.33 ± 1.27 vs. 91.95 ± 1.39), waste disposal (93.26 ± 1.24 vs. 89.65 ± 1.18), packaging and traceability (94.35 ± 1.74 vs. 92.23 ± 1.65), and issuance and recycling (95.79 ± 1.72 vs. 90.22 ± 1.81) (all P < 0.05). The observation group reported two adverse events (one incomplete instrument specification and one case of instrument package overweight) with an incidence rate of 0.67%. Conversely, the control group reported six adverse events (including shortages, incomplete specifications, unqualified sterilization, defective instruments, untimely or incorrect delivery, and overweight instrument packages) with an incidence rate of 3%, demonstrating statistically significant differences between groups (P < 0.05). Conclusion: Applying the PDCA cycle combined with instrument mapping for surgical instrument management in hospital sterilization supply centers significantly improves management quality and reduces adverse events. Its application is recommended for wider adoption in hospital sterilization supply centers.

Published: December 2024

The article explores the development of literary studies at Kazan University, reviewing the university scholars’ scientific research, highlighting their main aspects and scientific trends, determin- ing the role and contribution of the university scholars to Tatar literary studies. At Kazan University, it was in 1944 that Tatar literature was included in the curriculum and began to be taught as an academic discipline. The Department of Tatar Language and Literature was opened, attracting the leading literary scholars to this place. This phenomenon, in its turn, contributed to the development and diversification of scientific research in the field of Tatar literature in scientific- philological (the study of the Tatar literature development and literary criticism in various aspects) and methodological aspects (the development of a course of lectures, programs, textbooks and methodological guidelines for students of higher educational institutions, later for secondary school students). As the main object of our study, this article provides an analysis of this process, based on archival documents, research works, assessment of methodological and pedagogical activities of leading teachers, which accounts for the novelty and relevance of our work. The main objective of the research within the framework of this article is to describe the development of Tatar literary studies at Kazan University, identify its main aspects and the scientific foundations of this process, which has been carried out in line with the activities of the Department of Tatar Language and Literature, later the Department of Tatar Literature, organized at the University. In this regard, this article provides a complete overview of the Tatar Literature Department’s growth and development.

In this paper, we introduce the concept of an intuitionistic fuzzy n-controlled metric space (IFnCMS) by using \(n\) non-comparable functions \(\alpha_{i}:\Sigma\times\Sigma\rightarrow[1,\infty)\) \(\text{(1\(\leq i\leq n\))}\) in the inequalities having the form \(F(\varsigma^{o}_{1},\varsigma^{o}_{n+1},\iota^{o}_{1}+\iota^{o}_{2}+\dots+\iota^{o}_{n})\geq F\left(\varsigma^{o}_{1},\varsigma^{o}_{2},\frac{\iota^{o}_{1}}{\alpha_{1}(\varsigma^{o}_{1},\varsigma^{o}_{2})}\right)\) \(\ast F\left(\varsigma^{o}_{2},\varsigma^{o}_{3},\frac{\iota^{o}_{2}}{\alpha_{2}(\varsigma^{o}_{2},\varsigma^{o}_{3})}\right) \ast \dots \ast F\left(\varsigma^{o}_{n},\varsigma^{o}_{n+1},\frac{\iota^{o}_{n}}{\alpha_{n}(\varsigma^{o}_{n},\varsigma^{o}_{n+1})}\right)\) \(\text{for all } \iota^{o}_{n}>0\) and \(N(\varsigma^{o}_{1},\varsigma^{o}_{n+1},\iota^{o}_{1}+\iota^{o}_{2}+\dots+\iota^{o}_{n})\leq N\left(\varsigma^{o}_{1},\varsigma^{o}_{2},\frac{\iota^{o}_{1}}{\alpha_{1}(\varsigma^{o}_{1},\varsigma^{o}_{2})}\right)\) \(\circ N\left(\varsigma^{o}_{2},\varsigma^{o}_{3},\frac{\iota^{o}_{2}}{\alpha_{2}(\varsigma^{o}_{2},\varsigma^{o}_{3})}\right) \circ \dots \circ N\left(\varsigma^{o}_{n},\varsigma^{o}_{n+1},\frac{\iota^{o}_{n}}{\alpha_{n}(\varsigma^{o}_{n},\varsigma^{o}_{n+1})}\right)\) \(\text{for all } \iota^{o}_{n}>0\). Further, we provide some non-trivial examples and prove several fixed point results by utilizing an intuitionistic fuzzy version of Banach contraction and generalized \(\alpha-\phi-\)intuitionistic fuzzy contractive mapping in the setting of IFnCMS. Furthermore, we present some of its consequences to illustrate the significance of our results. Ultimately, we apply fractional differential equations used in economics to support the main result.

METHODS FOR ASSESSING THE EFFECTIVENESS OF A RECYCLING ECONOMY
Authors:   National University of Science and Technology MISIS, Korshunova Lyudmila N.
Published: December 2024

The article considers the issues of transition to a recycling economy in the electronics industry. It names those concerning constructing cyclic models in this area, associated with the spatial dispersion of places for production of electronic equipment and places of its use and subsequent transition
to the category of waste products of the electronic industry. It also analyzes
existing methods for assessing the effectiveness of recirculation models, their
advantages and limitations. The primary management objective is identified as
the one to protect human health and the environment from the adverse effects
of hazardous waste. The management objects of the waste management system
being formed are identified, which include the amount of waste and the costs of
collection, sorting, recycling and disposal.
The basic requirements for the indicators included in the efficiency assessment system are named: the ability to assess the level of waste generation and
disposal, the extent of pollution and the valuation of waste disposal costs. The
author formulates the criteria for management efficiency, they are: the equality
of special collections carried out to the costs of measures to reduce the amount
of waste and the high sensitivity of the amount of waste to the increase in the
above costs.

The article deals with substantiating the need to form a personoriented model of the economy as an adequate scientific and practical reflection
of the increase in complexity. The methodological basis of the study is an interdisciplinary approach to identifying forms of increasing political-economic
complexity, as well as the qualitative analysis in the field of substantiating the
new role of the human factor in modern economic reality. The scientific novelty
lies in the substantiation of the growing methodological significance of economic synergetics in the study of socio-economic relations.
The authors substantiate an imperative of consciously ensuring the coherence of the internal synergy of the individual and the external synergy of political and economic relations as the basis for sustainable socio-economic development. What seems new is the conclusion about the need for the establishment of new liberalism as a political-economic form of personality-oriented
economic development, relevant to the imperatives of expanded reproduction
of systems of tacit knowledge and creative-intellectual human capital. The scientific and practical significance of the article lies in the substantiation of such
a qualitative update of the current political economic model, where the synergetic “attractor” is the personality, appearing simultaneously as an “unfolded”
individual and a “collapsed” society; that is the essence and, at the same time,
the creative potential of the new “human dimension” of the economy

p. 702] belonging to one generation or another. For example, the people of
the generation in question prefer traveling to material goods. In their ranking of expenses, traveling the world gives way to savings for a down payment
on housing. They are quite picky about where they stay during their holidays.
Therefore, it is important for hoteliers to know and understand the value orientations and criteria that influence the choice of hotels by that target audience.
Through an indirect survey conducted using a questionnaire created in
Google Form, the authors managed to identify the key motives influencing the choice of a hotel by generation Z. Knowledge of these factors is crucial to
increase the competitiveness of the hotel, develop and implement its service
strategy based on personalization and understanding of preferences that determine expectations, and as a result, the choice of the hotel by “zoomers”.
In the context of the active development of domestic tourism in Russia, understanding the expectations and requests of generation Z is becoming increasingly relevant for hoteliers. The conducted research found that the generation in question travels quite often and, as a rule, chooses hotels of the
highest category as the main place of accommodation during travel, since the
quality of service and the level of service in them are much higher and the
service is personalized.

На поверхности подземных магистральных трубопроводов, находящихся в зоне влияния высоковольтных линий электропередачи номинальным напряжением 110 кВ и более, возникает наведенная электродвижущая сила (ЭДС). Наведенная ЭДС оказывает влияние на протекание коррозионного процесса и работу средств противокоррозионной защиты. На поверхности трубопроводов в современных заводских изоляционных покрытиях ЭДС может сохраняться длительное время. С целью изучения механизма коррозии под действием переменного тока разработан стенд, позволяющий исследовать одновременное воздействие переменного тока промышленной частоты 50 Гц и постоянного тока катодной защиты на металлические образцы. Описана конструкция стенда и методика проведения эксперимента. Проведено исследование зависимости скорости коррозии от величины плотности переменного тока, в результате которого получены кривые зависимости для различных значений поляризационных потенциалов. Установлено, что полученные кривые описываются кусочно-линейными зависимостями и имеют экстремум, соответствующий минимальной скорости коррозии. Также установлено, что переменный ток в зависимости от его плотности может оказывать как положительное, так и отрицательное воздействие. Результаты исследования свидетельствуют о нецелесообразности полного устранения переменной составляющей тока с защищаемых объектов. Возможно использование переменного тока в дополнение к катодной защите.

An induced EMF occurs on the surface of underground main pipelines located in the zone of influence of highvoltage power lines 110 kV and higher. The induced EMF influences the course of the corrosion process and the operation of anti-corrosion protection products. On the surface of pipelines in modern factory insulating coatings, EMF can persist for a long time. In order to study the mechanism of corrosion under the influence of alternating current, a stand has been developed that makes it possible to study the simultaneous effect of alternating current of industrial frequency 50 Hz and direct current of cathodic protection on metal samples. The design of the stand and the experimental procedure are described. A study was carried out of the dependence of the corrosion rate on the alternating current density, as a result of which dependence curves were obtained for various values of polarization potentials. It has been established that the resulting curves are described by piecewise linear dependencies and have an extremum corresponding to the minimum corrosion rate. It has also been established that alternating current, depending on its density, can have both positive and negative effects. The results of the study indicate that it is inappropriate to completely eliminate the alternating current component from the protected objects. It is possible to use alternating current in addition to cathodic protection.
Трещиностойкость нефтепровода с учетом двухосного стеснения деформаций по фронту поверхностной трещины

Published: December 2024

В настоящей работе проведена оценка трещиностойкости линейного участка магистрального нефтепровода на удалении от поперечного стыкового сварного шва на основе предложенного ранее авторами статьи нового двухпараметрического критерия разрушения, позволяющего учесть двухосное стеснение деформаций по фронту поверхностной полуэллиптической трещины. В основу данного критерия для наиболее часто встречающейся на практике трещины нормального отрыва положено предположение, что тангенциальные напряжения в зоне предразрушения равны локальной прочности материала. При этом размер зоны предразрушения и локальная прочность определяются не только с учетом коэффициента интенсивности напряжений, но и несингулярных Тхx- и Тzz-напряжений, входящих в асимптотическое распределение Вильямса для напряжений в окрестности трещины в трехмерном теле. Посредством этого получается учесть стеснение деформаций в окрестности фронта трещины как в поперечном направлении за счет Тхx-напряжений, так и в продольном направлении за счет Тzz-напряжений. Приведен пример реализации данного критерия для оценки трещиностойкости нефтепровода с поверхностной полуэллиптической продольной и поперечной трещинами. Результаты расчета представлены в виде зависимости критической глубины трещины от отношения полудлины трещины к ее глубине.

In this work, an assessment of the crack resistance of a linear section of a main oil pipeline at a distance from a transverse butt weld was carried out on the basis of a new two-parameter fracture criterion previously proposed by the authors of the article, which allows taking into account the biaxial constraint along the front of a surface semi-elliptical crack. This criterion for the most common crack in practice, namely, mode I crack, is based on the assumption that the tangential stresses in the fracture process zone are equal to the local strength of the material. In this case, the size of the fracture process zone and local strength are determined not only taking into account the stress intensity factor, but also nonsingular Txx- and Tzz-stresses included in the Williams asymptotic distribution for stresses in the vicinity of a crack in a three-dimensional body. Through this, it is possible to take into account the constraint in the vicinity of the crack front in the transverse direction due to Txx-stresses, and in the longitudinal direction due to Tzz-stresses. An example of the implementation of this criterion for assessing the crack resistance of an oil pipeline with a surface semi-elliptical longitudinal and transverse crack is given. The calculation results are presented as the dependence of the critical crack depth on the ratio of the crack half-length to its depth.

The pandemic period revealed insufficient training of teachers in the field of technology, and this aspect
directly influences the instructional-educational act carried out online with students. Teacher training to
use technology for education-related purposes is closely correlated with the individual ability to adapt to
contemporary challenges, but also to the continuous training that each teacher must undertake in his
career, considering the multitude of digital tools that facilitate the didactic activity and facilitate learning
by the students. The financial education of students is a necessary discipline in the formation of the
individual for the future and society, and a correct acquisition of economic notions can be facilitated by
technology, through appropriate digital resources. We believe that the foundations of a minimum financial
education should be laid in the primary classes, to form student's skills related to financially responsible
behavior - a very problematic aspect in the education system, because it does not offer such a discipline in
the common core of the school curriculum. One solution regarding the implementation of financial
education in primary school students would be the delivery of such education by the technology-savvy
teacher so that the content taught is presented in an attractive form for students. Training future teachers to
implement financial education through digital resources is a challenge. In the following, we will present
the results of a research carried out following the author's teaching activity at the “Vasile Alecsandri”
University of Bacău, Romania, within the discipline “Computer Assisted Instruction and Online
Educational Platforms”. The research aim was to explore the capacity of future teachers to adopt various
technological solutions for a quality educational act. Finally, we will suggest a professional profile of the
modern teacher - adapted to modern methods of implementing financial education.

Hospitals have been competing to provide the best services in order to gain patient loyalty. Patient loyalty can be assessed from patient satisfaction and experience during hospitalization. This study aims to analyse the influence of patient experience and patient satisfaction on patient loyalty in the Outpatient Installation of Darmo Hospital. An analytical observational study using a cross-sectional approach was used in this study. The sample used in this study was 181 patients who were treated in the outpatient installation of Darmo Hospital Surabaya, selected using proportionate stratified random sampling technique. The independent variables in this study were patient experience and satisfaction, while the dependent variable was patient loyalty. Data was collected using a questionnaire and analyzed using logistic regression. The results showed a significant influence of patient experience on satisfaction (0.0001), patient experience on loyalty (0.0001), and satisfaction on loyalty (0.0001). Patient loyalty can be achieved by improving and enhancing patient experience, as better patient experience leads to increased patient satisfaction and loyalty towards the hospital. To gain patient loyalty, hospital services must be improved based on feedback in accordance with patients' wishes.
