Effect of Roller Burnishing and Slide Roller Burnishing on Fatigue Strength of AISI 304 Steel: Comparative Analysis
Authors: Duncheva Galya , Maximov Jordan , Anchev Angel , Dunchev Vladimir , Anastasov Kalin , Argirov Yaroslav
Published: June 2024

The new slide roller burnishing (SRB) method has been developed to produce mirror-like surfaces. Unlike conventional roller burnishing (RB), SRB is implemented through a unique device that allows the axes of the deforming roller and the rotary workpiece to cross, resulting in a relative sliding velocity that can be controlled (in magnitude and direction) by varying the crossing angle. In the present work, the effect of SRB on the fatigue behavior of AISI 316 steel fatigue specimens was investigated by comparing it with conventional RB using the following basic correlation in surface engineering: finishing–surface integrity (SI)–operating behavior. To obtain a more representative picture of the comparison, we implemented each method (RB and SRB) with two combinations of governing factors—(A) a radius of the roller toroidal surface of 3 mm, a burnishing force of 250 N, and a feed rate of 0.05 mm/rev (RB-A and SRB-A), and (B) a radius of the roller toroidal surface of 4 mm, a burnishing force of 550 N, and a feed rate of 0.11 mm/rev (RB-B and SRB- B). Both SRB-A (a crossing angle of –45°) and SRB-B (a crossing angle of –30°) achieved mirror-finish surfaces. SRB-B lead to the greatest fatigue strength and, thus, the longest fatigue life among all tested processes. SRB-B created the deepest zone (>0.5 mm) with residual compressive macro-stresses and a clearly defined modified surface layer, whose thickness of more than 20 μm is about twice that created by the other three processes.

Published: June 2024

Wire Arc Additive Manufacturing (WAAM) of thin walls is an adequate technology for producing functional components made with aluminium alloys. The AlMg5 family is one of the most applicable alloys for WAAM. However, WAAM differs from traditional fabrication routes by imposing multiple thermal cycles on the material, leading the alloy to undergo cyclic thermal treatments. Depending on the heat source used, thermal fluctuation can also impact the microstructure of the builds and, consequently, the mechanical properties. No known publications discuss the effects of these two WAAM characteristics on the built microstructure. To study the influence of multiple thermal cycles and heat source-related thermal fluctuations, a thin wall was built using CMT-WAAM on a laboratory scale. Cross-sections of the wall were metallographically analysed, at the centre of a layer that was re-treated, and a region at the transition between two layers. The focus was the solidification modes and solubilisation and precipitations of secondary phases. Samples from the wall were post-heat treated in-furnace with different soaking temperatures and cooling, to support the results. Using numerical simulations, the progressive thermal cycles acting on the HAZ of one layer were simplified by a temperature sequence with a range of peak temperatures. The results showed that different zones are formed along the layers, either as a result of the imposed thermal cycling or the solidification mode resulting from CMT-WAAM deposition. In the zones, a band composed of coarse dendrites and an interdendritic phase and another band formed by alternating sizes of cells coexisted with the fusion and heat-affected zones. The numerical simulation revealed that the thermal cycling did not significantly promote the precipitation of second-phase particles.

Published: June 2024

A chemical and biological exploration of the European polypore Dentipellis fragilis afforded two previously undescribed natural products (1 and 2), together with three known derivatives (3–5). Chemical structures of the isolated compounds were confirmed through 1D/2D NMR spectroscopic analyses, mass spectrometry, and by comparison with the reported literature. The relative and absolute configurations of 1 were determined according to the ROESY spectrum and time-dependent density functional theory electronic circular dichroism (TDDFT-ECD), respectively. Furthermore, the absolute configuration of dentipellinol (3) was revisited and revealed to be of (R) configuration. All the isolated compounds were assessed for their cytotoxic and antimicrobial activities, with some being revealed to have weak to moderate antimicrobial activity, particularly against Gram-positive bacteria.

Published: June 2024

A mild, efficient and practical protocol for the preparation of 2-sulfonylquinolines through CS2/Et2NH-induced deoxygenative C2-H sulfonylation of quinoline N-oxides with readily available RSO2Cl was developed. The reaction proceeded well under transition-metal-free conditions and exhibited a wide substrate scope and functional group tolerance. The preliminary studies suggested that the nucleophilic sulfonyl sources were generated in situ via the reaction of CS2, Et2NH and sulfonyl chlorides.

Atherosclerosis continues to be a leading cause of morbidity and mortality globally. The precise evaluation of the extent of an atherosclerotic plaque is essential for forecasting its likelihood of causing health concerns and tracking treatment outcomes. When compared to conventional methods used, nanoparticles offer clear benefits and excellent development opportunities for the detection and characterisation of susceptible atherosclerotic plaques. In this review, we analyse the recent advancements of nanoparticles as theranostics in the management of atherosclerosis, with an emphasis on applications in drug delivery. Furthermore, the main issues that must be resolved in order to advance clinical utility and future developments of NP research are discussed. It is anticipated that medical NPs will develop into complex and advanced next-generation nanobotics that can carry out a variety of functions in the bloodstream.

Authors: Lee Joung Eun , Kim Jung-Yeon , Leem Jaechan
Published: June 2024

Cisplatin, a platinum-based chemotherapeutic, is effective against various solid tumors, but its use is often limited by its nephrotoxic effects. This study evaluated the protective effects of trametinib, an FDA-approved selective inhibitor of mitogen-activated protein kinase kinase 1/2 (MEK1/2), against cisplatin-induced acute kidney injury (AKI) in mice. The experimental design included four groups, control, trametinib, cisplatin, and a combination of cisplatin and trametinib, each consisting of eight mice. Cisplatin was administered intraperitoneally at a dose of 20 mg/kg to induce kidney injury, while trametinib was administered via oral gavage at 3 mg/kg daily for three days. Assessments were conducted 72 h after cisplatin administration. Our results demonstrate that trametinib significantly reduces the phosphorylation of MEK1/2 and extracellular signal-regulated kinase 1/2 (ERK1/2), mitigated renal dysfunction, and ameliorated histopathological abnormalities. Additionally, trametinib significantly decreased macrophage infiltration and the expression of pro-inflammatory cytokines in the kidneys. It also lowered lipid peroxidation by-products, restored the reduced glutathione/oxidized glutathione ratio, and downregulated NADPH oxidase 4. Furthermore, trametinib significantly inhibited both apoptosis and necroptosis in the kidneys. In conclusion, our data underscore the potential of trametinib as a therapeutic agent for cisplatin-induced AKI, highlighting its role in reducing inflammation, oxidative stress, and tubular cell death.
How to Improve Surveillance Program for Shiga Toxin-Producing E. coli (STEC): Gap Analysis and Pilot Study
Authors: Sora Valerio Massimo , Zaghen Francesca , Zecconi Alfonso
Published: June 2024

Several pathotypes of enteric E. coli have been identified. The group represented by Shiga toxin-producing E. coli (STEC) is of particular interest. Raw milk and raw milk products are significant sources of STEC infection in humans; therefore, identifying pathogens at the herd level is crucial for public health. Most national surveillance programs focus solely on raw milk and raw milk cheeses that are ready for retail sale, neglecting the possibility of evaluating the source of contamination directly at the beginning of the dairy chain. To assess the viability of the application of new molecular methodologies to STEC identification in raw milk filters and in calf feces, we analyzed 290 samples from 18 different dairy herds, including 88 bulk tank milk (BTM), 104 raw milk filters (RMF), and 98 calf feces samples. In total 3.4% of BTM, 41.4% of RMF, and 73.4% of calves’ feces were positive for stx, supporting our hypothesis that BTM is not a suitable matrix to assess the presence of STEC at herd level, underestimating it. Our conclusion is that the surveillance program needs critical and extensive improvements such as RMF and calves’ feces analysis implementation to be more efficient in detecting and preventing STEC infections. The epidemiology of these infections and the characteristics of the pathogen clearly show how a One Health approach will be pivotal in improving our capabilities to control the spread of these infections.

Published: June 2024

Cadmium (Cd) pollution has been rapidly increasing due to the global rise in industries. Cd not only harms the ecological environment but also endangers human health through the food chain and drinking water. Therefore, the remediation of Cd-polluted soil is an imminent issue. In this work, ryegrass and a strain of Cd-tolerant bacterium were used to investigate the impact of inoculated bacteria on the physiology and biochemistry of ryegrass and the Cd enrichment of ryegrass in soil contaminated with different concentrations of Cd (4 and 20 mg/kg). The results showed that chlorophyll content increased by 24.7% and 41.0%, while peroxidase activity decreased by 56.7% and 3.9%. In addition, ascorbic acid content increased by 16.7% and 6.3%, whereas glutathione content decreased by 54.2% and 6.9%. The total Cd concentration in ryegrass increased by 21.5% and 10.3%, and the soil’s residual Cd decreased by 86.0% and 44.1%. Thus, the inoculation of Cd-tolerant bacteria can improve the antioxidant stress ability of ryegrass in Cd-contaminated soil and change the soil’s Cd form. As a result, the Cd enrichment in under-ground and above-ground parts of ryegrass, as well as the biomass of ryegrass, is increased, and the ability of ryegrass to remediate Cd-contaminated soil is significantly improved.

Published: June 2024

Municipal waste biomass could be valorized as an alternative feedstock to produce compounds beneficial for agricultural applications. The foliar spray application of biostimulants emerges as a promising and innovative technique due to its environmental safety and ability to enhance crop yields. In recent years, the exploitation of biopolymers obtained through alkaline hydrolysis of the solid anaerobic digestate from municipal biowastes has attracted researchers’ interest. The aim of this study is to investigate the effects on lettuce growth of a product obtained through alkaline hydrolysis from municipal biowaste, Biopolymers (BPs), and of a derivate subjected to a further oxidation process, Biopolymers Oxidate (BPs OX). The effects of the treatments at various concentrations were evaluated by monitoring plant growth and observing the trends in the activities of the main enzymes involved in the nitrogen metabolic pathway of lettuce. Results suggest that the best treatments in terms of fresh weight were achieved by using BPs at 10 mg/L and BPs OX at 100 mg/L, increasing yield by around 28% and 34%, respectively. The innovative aspect of this work was to make easier for farmers the biopolymers application by testing a foliar spray methodology for BPs and BPs OX, which has never been tested before in any crop.

Authors: Zhou Ning , Ma Sen , Zhang Minwei , Wang Jiayi
Published: June 2024

With the internationalization of Chinese culture, ready-to-cook Chinese food has become popular. Vegetables in Chinese preparations are usually cut into slices, cubes, and shreds. Carrots, as a typical Chinese side dish, were selected as the model in this work. The polyphenol content, antioxidant capacity, O2−, hydrogen peroxide, malondialdehyde, lignin, antioxidant enzymes, and other enzymes activities were analyzed. The results indicated that these parameters were insignificantly different between three cutting styles. Therefore, metabolomics is further employed. Pathway enrichment indicated that glyceollin II and 6″-malonylgenistin were metabolites particularly expressed in the isoflavonoid biosynthesis pathway; (+)-gallocatechin, trans-chlorogenic acid, and (−)-epiafzelechin were specifically identified in the flavonoid biosynthesis pathway after slicing; and shredding caused the expression of coniferyl aldehyde and eugenol, which were specifically expressed in the phenylpropanoid biosynthesis pathway. These results indicate that different cutting styles do not change the physiological indicators of carrots but induce the expression of specific metabolites.
Separate and Combined Effects of Supplemental CO2, Gibberellic Acid, and Light on Hop Quality and Yield
Authors: Bauerle William L.
Published: June 2024

We investigated the effect of supplemental CO2, gibberellic acid (GA3), and light on the quality and yield of Humulus lupulus L. strobili (cones). When applied separately, CO2 and light increased the yield by 22% and 43%, respectively, and had a significant effect on the components of cone mass and quality. Exogenous GA3 increased flower set; however, the yield decreased by approximately 33%. Combining CO2, GA3, and light, and any combination thereof, resulted in significant increases in flower set and cone yield enhancement compared to separate applications. A synergistic effect occurred when some factors were combined. For example, the combination of CO2 and light resulted in a yield increase of approximately 122%. The combination of all three resources, CO2, GA3, and light, resulted in an approximate 185% yield increase per plant. Thus, in comparison to the addition of one supplementary resource, a greater increase in yield resulted from the combination of two or more supplemental resources. Flower set stimulation due to GA3 decreased cone alpha- and beta-acid quality attributes, unless combined with CO2 and light as additional carbohydrate-generating resources. Additional research is needed to close the hop yield gap between current hop yields and the achievement of the plant’s genetic potential.
Phytochemistry and Biological Activities of Agrostemma Genus—A Review
Authors: Smakosz Aleksander , Matkowski Adam , Nawrot-Hadzik Izabela
Published: June 2024

The family Caryophyllaceae comprises more than 2600 species spread widely across all the continents. Their economic importance is mainly as ornamentals (carnation) and as weeds in agriculture. Some species have been used traditionally (and some are still) in herbal medicine or as emulsifiers in food processing. These applications are based on the high content of triterpenoid saponins. Typical for this family are also ribosome-inactivating proteins (RIPs), which are potentially highly toxic. Agrostemma githago L. (common corncockle) was historically considered a serious toxicological hazard owing to cereal grain contamination by its seeds. Notwithstanding, it was also recommended as a drug by various herbalists. In this review, the literature was searched in the PubMed, Google Scholar, and Scopus databases for papers focused on the chemical composition and bioactivity of the two accepted species of the Agrostemma genus. This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and MetaAnalysis (PRISMA) guidelines. Current research reports the cytotoxicity against neoplastic cells; the protection against oxidative stress; the suppression of Leishmania major culture growth; the inhibition of protein synthesis; and the antiviral, anti-angiogenic, and antihypercholesterolemic activities of common corncockle. The future prospects of using A. githago saponins as adjuvants in drug formulations and enhancing the cytotoxicity of RIPs are also discussed.

Published: June 2024

The tourist intermediary industry has faced multiple challenges to adapt their offers to the heterogeneity of tourists, and understanding consumer interests from a gender and age perspective is considered crucial in the design and marketing of tourist products. The aim of this article is to examine the differences generated by the gender and age variables of consumers of Spanish travel agencies when choosing travel and tourist destinations, focusing on different types of travel, the choice between national and international destinations, and specific destination types. An explanatory quantitative methodology was employed with a hypothetical-deductive approach. A questionnaire was administered to individuals who booked through Spanish travel agencies and a sample of 879 was obtained. The data were analyzed using SPSS 26 software and the main statistical tool was the Pearson Chi-Square (χ2) test. The findings show that gender implies significant differences in travel preferences, with women favoring the exploration of new destinations and men preferring relaxation travel. Age groups impact the choice between national and international travel, but have a lesser effect on specific destination preferences. This research underscores the importance of considering gender and age in understanding consumer behavior within the travel sector, with the aim of developing more effective marketing strategies and catering to diverse customer needs. Within the implications, the growing importance of the older traveler segment should be highlighted, which requires future research and comparisons with the younger traveler segment.
mRNA Technology and Mucosal Immunization
Authors: Toniolo Antonio , Maccari Giuseppe , Camussi Giovanni
Published: June 2024

Current mRNA vaccines are mainly administered via intramuscular injection, which induces good systemic immunity but limited mucosal immunity. Achieving mucosal immunity through mRNA vaccination could diminish pathogen replication at the entry site and reduce interhuman transmission. However, delivering mRNA vaccines to mucosae faces challenges like mRNA degradation, poor entry into cells, and reactogenicity. Encapsulating mRNA in extracellular vesicles may protect the mRNA and reduce reactogenicity, making mucosal mRNA vaccines possible. Plant-derived extracellular vesicles from edible fruits have been investigated as mRNA carriers. Studies in animals show that mRNA vehiculated in orange-derived extracellular vesicles can elicit both systemic and mucosal immune responses when administered by the oral, nasal, or intramuscular routes. Once lyophilized, these products show remarkable stability. The optimization of mRNA to improve translation efficiency, immunogenicity, reactogenicity, and stability can be obtained through adjustments of the 5′cap region, poly-A tail, codons selection, and the use of nucleoside analogues. Recent studies have also proposed self-amplifying RNA vaccines containing an RNA polymerase as well as circular mRNA constructs. Data from parenterally primed animals demonstrate the efficacy of nasal immunization with non-adjuvanted protein, and studies in humans indicate that the combination of a parenteral vaccine with the natural exposure of mucosae to the same antigen provides protection and reduces transmission. Hence, mucosal mRNA vaccination would be beneficial at least in organisms pre-treated with parenteral vaccines. This practice could have wide applications for the treatment of infectious diseases.

The study provides an eco-phytocenotic characterization and assessment of regional floral rarities in the Poltava region. The distribution conditions of these rarities are considered, along with proposed strategies for conserving and protecting valuable plant species. The research results are important for understanding the region’s biodiversity and developing conservation programs for natural ecosystems.The results of the expeditionary research conducted by the authors from 2006 to 2023 indicate that there are 12 species of rare flora in the studied region. Of these, 7 species are forest-dwelling, 1 is found in marshes, and 4 are characteristic of salt marshes and saline meadows. Four species grow at the western and southern borders of their range in the Poltava region two at the eastern border, and two species more are represented by isolated localities. These species require special protection and attention, making it crucial to preserve all identified localities of these rare species, investigate the condition of their populations, and monitor their status in the future.
The Empire-Universe and Its area. On the Application of the Concept of State-Civilization to the History of Byzantium
Authors: Кузенков П.В.
Published: June 2024

В современной науке все более широко и плодотворно разрабатывается концепт «государства-цивилизации», который в последнее время активно используется, в частности, в официальных документах. Именно в этом ракурсе следует, по нашему убеждению, вести анализ феномена Византийской империи. Это, в свою очередь, ставит ряд нетривиальных исследовательских задач, актуальных не только для исторической науки, но и для изучения современных цивилизационных процессов. Одной из таких задач является реконструкция политико-географических представлений, в рамках которых происходило становление и развитие военно-административных и церковных институций средневековой восточнохристианской цивилизации — «византийского мира». В тесной взаимосвязи с этой задачей находится и проблема выявления динамики соотношений политического, церковного и культурного планов в исторической географии Византии.

In modern science, the concept of «state-civilization» is being increasingly and fruitfully developed, which has recently been actively used, in particular, in official documents. It is from this perspective that, in our opinion, one should analyze the phenomenon of the Byzantine Empire. This, in turn, poses a number of nontrivial research problems that are relevant not only for historical science, but also for the study of modern civilizational processes. One of these tasks is the reconstruction of political and geographical ideas within which the formation and development of military-administrative and church institutions of the medieval Eastern Christian civilization — the «Byzantine world» — took place. Closely related to this task is the problem of identifying the dynamics of the relationships between the political, church and cultural plans in the historical geography of Byzantium.

The study aims at finding out the gender perspectives on job satisfaction of librarians at Kenya National Library Service (KNLS). The study  establish how pay, promotion, supervision and working conditions and gender affects job satisfaction and motivation between female and male librarians. Descriptive survey design method was adopted allow for an extensive review of the study phenomenon. Cluster sampling was used to select 8 KNLS branch libraries from the 8 regions in Kenya namely; Eastern, Western, Nairobi, Rift valley, Nyanza, North Eastern, Costal and Central region. Simple random sampling was applied to pick one library in regions with more than one KNLS branch libraries. The Sample size studied was made of 120 librarians; 69 female librarians and 51 male librarians. Primary data was collected using questionnaires from both female and male librarians at KNLS. Collected data was processed and analysed using descriptive and Pearson chi square was used to test the difference between female and male librarians’ perspectives on job satisfaction and motivation. The mean of job satisfaction on pay, promotion, supervision as well as working conditions were higher among the females (3.733, 3.9533, 39533 3.6286 respectively) than the males (3.6963, 3.8711, 3.9181 and 4.0357 respectively). The research findings indicate that there was no significant difference on job satisfaction between female and male librarians at Kenya National Library Service. The study also concluded that there is no significant difference in the overall job satisfaction. It is however essential that librarian are treated equally irrespective of their gender.

Authors: Ruslan Malikov, Gulam Babayev Ruslan Malikov, Gulam Babayev
Published: June 2024

Geophysics is the branch of Earth science that applies the principles and methods of physics to the study of the Earth. Recent advances in artificial intelligence (AI), particularly machine learning (ML) and deep learning (DL), are transforming the field by providing powerful tools for data processing, analysis, and prediction. Traditional geophysical methods are often challenged by data complexity, non-unique solutions, and human interpretation limitations. AI algorithms trained on large datasets can identify intricate patterns and relationships within the data, leading to improved accuracy and efficiency. In this review, we provide an overview of the development of AI in the geophysical field such as seismic exploration. Specific examples illustrate the application of AI in geophysical workflows, highlighting the results achieved in areas such as seismic data processing, reservoir characterization, and automated seismic interpretation.

In the experimental department of the Urals research center for radiation medicine (Chelyabinsk, Russia) the radiobiological studies are carried out with the IGUR-1M gamma installation. In this study, the numerical experiment has been performed to specify the radiation doses in experimental mice and corresponding uncertainties. We evaluate the factors converting the dose in air measured by the ionization chamber to the dose to an organism, which is dependent on the height of the cage with the animals. The relative standard uncertainties of radiation doses for mice under 7 days of age do not exceed 7%. For more active older animals, the uncertainty of the delivered radiation doses can reach 10%.

Actualmente Colombia es epicentro de un conflicto interno armado compuesto por diferentes Agentes Generadores de Violencia (AGV), que centran su accionar delictivo en la obtención de rentas ilícitas por medio del narcotráfico y otras actividades clandestinas, en este proceso buscan afectar a la fuerza pública por medio de ataques simultáneos y preparados como por ejemplo emboscadas, ataques con explosivos, francotiradores, campos minados entre otras prácticas ilegales. Los intereses de los grupos armados son claros, teniendo como base principal la prevalencia de la ideología revolucionaria y el incremento de sus finanzas con el fin de lograr prevalecer al pasar el tiempo. Están dispuestos a colocar por encima de cualquier cosa el financiamiento y evolución de los diferentes componentes de la organización, para ello proyectan estrategias de presión y superioridad ante el gobierno a través de la afectación de unidades militares y policiales por medio del asesinato de estos, originando de esta manera las confrontaciones armadas. Por otra parte, la fuerza pública trabaja de forma mancomunada con el propósito de contrarrestar los objetivos ilícitos de los diferentes Agentes Generadores de Violencia en Colombia, buscando la manera de afectar sus intereses por medio de la ejecución de operaciones de acción directa, operaciones psicológicas, operaciones de control territorial entre otras. En este cruce de intereses la fuerza pública termina en confrontación armada con los Grupos Armados Ilegales (GAO). En mencionados combates, en la mayoría de ocasiones termina dejando como resultado personal subversivo herido o neutralizado, de igual manera en las unidades militares o policiales, lo cual genera una serie de emociones y sentimientos en el personal que se involucra en el desarrollo de la confrontación armada, lo más curioso es que los integrantes de la fuerza pública no reciben un entrenamiento idóneo en el área psicológica para implementar mejores acciones en el campo de batalla y así de esta manera generar un desempeño más óptimo. Los centros de formación y las escuelas de formación de Oficiales y Suboficiales de la Infantería de Marina Colombiana no son ajenos a esta falencia, se consultó por medio de una encuesta a personal de Oficiales, Suboficiales e Infantes de Marina Profesionales con trayectoria en la institución si en determinado momento de su carrera militar habían recibido formación psicológica para responder durante el desarrollo de combates a lo cual respondió que en ningún momento había recibido esa instrucción.
