Published: December 2024

The culinary business world is currently developing very rapidly, especially in the city of Manado, which has great potential for hot chilli sauce products such as Rica Roa. The “Rokla” business comes with innovation using pure coconut oil (VCO), which is known to be healthier than the copra coconut oil that is generally used. This chilli sauce not only has a distinctive spicy taste, but also offers a unique taste thanks to the us of VCO. However, this business still in the early development stage,so it requires careful marketing planning. For this reason, a SWOT analysis is carried out to identify the strengths, weaknesses, opportunities and threats facing this business. Apart from that, the IFAS and EFAS matrices are also used to deepen the analysis and find the most appropriate marketing strategy. After analysing the SWOT, the STP (Segmenting, Targeting and Positioning) strategy is applied to determine the appropriate target market. Next, the 4P marketing mix (Product, Price, Place, Promotion) is used to implement the strategy that has been formulated. With this approach, it is hoped that the “Rokla” business can expand its market reach and increase its competitiveness, especially through digital promotion strategies and expanding distribution to various potential market segments.

ARCHAEOLOGICAL CATALOGS AND MAPS OF THE WEST OF UKRAINE: FROM THE PAST TO NOWADAYS
Authors: PETEHYRYCH Volodymyr
Published: December 2024

Written, archaeological, and cartographic sources and literature related to the problem of cataloguing and mapping archaeological sites in the West of Ukraine were collected and analyzed. It has been established that archaeological catalogues and maps have a long transformation from the first mentions of sites in chronicles to the modern stage of the development of archaeological science with developed scientific and methodological apparatus, the use of information technologies, and the formation of electronic databases.

Five periods of the process of creating archaeological catalogues and maps are distinguished: the oldest catalogues and maps; the beginnings of scientific mapping in the late 19th and early 20th centuries; cataloguing and mapping of sites between the World Wars I and II; archaeological catalogues and maps of the second half of the 20th century; cataloguing and mapping of sites in the years of independence. Each of the defined periods is filled with carefully collected materials, their specificity is highlighted, and the gradual expansion and diversification of the spectrum of catalogues and maps of various types of archaeological sites. For the first time, together with well-known universal and thematic catalogues, maps of individual sites, objects, artifacts, and phenomena, archaeological catalogues, and maps of historical cities of the West of Ukraine have been shown.

The importance of international cooperation in the study of the archaeological heritage of Ukraine, in particular with the participation of Polish scientific institutions, was emphasized. As a result of such cooperation, many white spots in the basin of the Upper Dnister region were eliminated. The participation of foreign researchers in replenishing catalogues and maps with those materials from the territory of the West of Ukraine, which due to historical circumstances ended up in museum collections outside our country, was noted.

Taking into account the growing threat of illegal use of catalogues and maps with detailed localization of archaeological sites, the need to improve Ukrainian site protection legislation considering the norms of international law and the provisions of the European Convention on the Protection of Archaeological Heritage is emphasized.

Keywords: West of Ukraine, archaeological sites, artifacts, phenomena, catalogue, map, history of creation.

The hypersaline northwestern Arabian Gulf contains a phylogenetically diverse and highly uneven community of viruses related to cyanophages and pelagiphages
Authors: Almutairi A , Suttle CA , Gustavsen JA
Published: December 2024

Cyanobacteria are the dominant primary producers in many marine waters, and are intimately connected with the cyanophages that infect them. The most commonly isolated marine cyanophages form a monophyletic group based on several marker genes including g20, a gene that codes the capsid assembly protein. Based on morphology, these viruses are typically referred to as cyanomyoviruses. Here, we used g20 sequences to interrogate the diversity of cyanomyoviruses at 5 locations in the waters of the northwestern Arabian Gulf. The diversity and richness of g20 sequences varied among locations and were highest at the southernmost sites. Most sequences belonged to a small number of operational taxonomic units (OTUs), with the rest belonging to low abundance rare OTUs. Phylogenetic analysis revealed that the most abundant genotypes fell within the ubiquitous cyanomyovirus Cluster II, while others clustered with metagenome assembled pelagimyophage sequences and other environmental sequences across a broad diversity of clades. This study revealed a diverse community of cyanomyoviruses in the northwestern Arabian Gulf that is dominated by a few relatively abundant but phylogenetically diverse taxa.

The influence of yoga exercises with voluntary pulmonary ventilation changes on intracranial arterial blood flow
Authors: Frolov A. V. , Ermolaeva S. A. , Didur M. D.
Published: December 2024

Introduction. Yoga breathing exercises that involve voluntary changes in pulmonary ventilation parameters can potentially influence cerebral circulation due to changes in CO2 content in arterial blood. Objective. To assess the effect of yoga breathing exercises with changes in pulmonary ventilation levels on blood flow parameters in the middle cerebral artery (MCA). Methods. The study included 21 participants, with an average age of 39.5±8.7 years, who were capable of performing yoga exercises at respiratory rates (RR) of 3–3.5/min and 1–1.5/min. For 5 minutes, participants underwent three stages: free breathing (stage 1), breathing with RR=3–3.5/min (stage 2), and breathing with RR=1–1.5/min (stage 3). During stages 2 and 3, the «full breathing» technique, which involves maximum deep inhalation and exhalation, was employed. Respiratory rate (RR), tidal volume (TI), minute ventilation (MV), end-tidal CO2 partial pressure (PetCO2), and oxygen fraction in exhaled air (FeO2) were recorded using spiro-gas analysis. Transcranial duplex scanning was used to measure peak systolic blood flow velocity (Vps), end-diastolic blood flow velocity (Vd), time-averaged maximum blood flow velocity (TAMAX), and resistance index (RI) in the right MCA. The velocity variation index (VVI) was calculated for each stage. Results. Compared to stage 1 (free breathing), stage 2 (RR = 3–3.5/min) showed an increase in MV and FeO2, a decrease in PetCO2, and reductions in Vps, Vd, and TAMAX, with an increase in RI. VVI decreased statistically insignificantly. In stage 3 (RR = 1–1.5/min), compared to stage 1, there was an increase in PetCO2, a decrease in MV and FeO2, and increases in Vps, Vd, and TAMAX, with a decrease in RI. VVI increased significantly. Conclusions. Yoga breathing exercises at respiratory rates of 3–3.5/min and 1–1.5/min result in multidirectional shifts in ventilation and gas exchange parameters, leading to changes in arterial cerebral blood flow (a decrease and increase in blood flow velocity with an increase and decrease in MV, respectively). VVI, reflecting fluctuations in blood flow velocity, increases significantly with reduced MV, likely due to the vasodilatory effect of CO2.

Spinach is susceptible to various fungal, bacterial, and viral pathogens. Among these, bacterial leaf spot poses a significant threat, leading to substantial reductions in both yield and quality. Recent research focused on evaluating different plant defense activators for their effectiveness against bacterial leaf spot in spinach. Of the tested activators, Salicylic acid showed the lowest disease severity and incidence, with values of 24.76% and 27.73%, respectively, followed by Citric acid (27.43%, 32.76%), Benzoic acid (29.57%, 38.32%), and K2HPO4 (33.31%, 38.38%) under greenhouse and field conditions, compared to the control. Various epidemiological factors—including temperature (minimum and maximum), relative humidity (%), rainfall (mm), and wind speed (km/h)—were assessed for their impact on disease development in three local spinach varieties: Dasi Palak, Lahori Palak, and Swiss Chard Palak. The results showed that disease severity increased considerably when the temperature ranged from 26-28°C, relative humidity was 69-73%, rainfall was 0.5-1 mm, and wind speed was 1.5-2 km/h. All environmental factors exhibited a positive correlation with the development of bacterial leaf spot in spinach. Greenhouse and field trials were conducted using a Complete Randomized Design (CRD) and a Randomized Complete Block Design (RCBD), respectively. Based on the findings, the application of Salicylic acid is recommended as a reliable and ecologically sound strategy for managing bacterial leaf spot in spinach.

Published: December 2024

The present study assessed peanut genotypes for resistance to Cercospora leaf spot (CLS), with a focus on disease severity and defoliation across different growth stages. Based on Percent Incidence Data (PID) and defoliation scores, genotypes were classified as susceptible, moderately resistant, or resistant. Disease progression was measured through the Area under the Disease Progress Curve (AUDPC), revealing significant variation in resistance among the genotypes. Most genotypes, including 21CG001, 21CG002, 21CG003, 21CG004, 21CG006, ATTOCK 19, and 20AK012, exhibited high PID and defoliation levels, with AUDPC values indicating susceptibility. Their PID ranged from 23.96 to 31.72 at 50 days after sowing (DAS) and from 44.84 to 56.97 at 70 DAS. Genotypes 21CG005, 20AK004, and ATTOCK 19 showed the highest PID and defoliation levels, with AUDPC values over 320, categorizing them as highly susceptible. Conversely, genotypes 21CG007, 21CG008, 20AK001, and 20AK010 demonstrated the lowest PID, minimal defoliation, and AUDPC values below 250, indicating strong resistance. In vitro trials further highlighted variability in lesion characteristics, with genotypes 20AK012, BARI 16, and 20AK010 showing the most severe symptoms, including rough lesion textures and types ranging from minute chlorotic spots to mature black lesions. Overall, genotypes 21CG007, 21CG008, 20AK001, and 20AK010 exhibited high resistance, while ATTOCK 19, 20AK004, and 21CG005 were highly susceptible. These findings underscore the importance of selecting resistant genotypes for effective CLS management in peanut cultivation.

Maize (Zea mays L.), an herbaceous plant of Poaceae family, is the staple food of many people in developing countries. However, this product, as all crops, suffers from several biotic constraints during post-harvest storage. Among these constraints, molds caused by phytopathogenic fungi are the most important. The present study aimed to contribute to food security by characterizing fungal pathogens in stored maize grains. A survey was carried out in 10 communes of the Autonomous District of Abidjan, followed by sampling of maize grains stored. Samples were labelled and then taken to laboratory for analysis. Fungal isolation was carried out on PDA (Potato Dextrose Agar) medium. Morphological characterization of the different fungal genera obtained was carried out after isolation. Results showed that maize grain wholesale trade is mainly held by men (72%) and that 85% of those traders are educated. Six (6) fungal genera were morphologically identified. These are Aspergillus, Fusarium, Rhizopus, Pythium, Botryodiplodia and Trichoderma. Among these fungal genera, Aspergillus was the most isolated with a rate of 60.65%, followed by Fusarium (30.28%). Aspergillus and Fusarium fungal species are toxigenic and can produce mycotoxins under the right conditions. They require special attention in order to propose effective and sustainable solutions to their control.

Published: December 2024

Rice blast disease, caused by Pyricularia oryzae, is one of the most destructive and devastating fungal diseases affecting rice crops. Traditionally, the disease is managed through host resistance and the application of fungicides; however, the latter approach is environmentally toxic and not always feasible. The objective of the present study was to evaluate the effectiveness of various nutrients, both individually and in combination, for disease control. Greenhouse experiments were conducted over two consecutive years, 2019 and 2020, to assess three nutrients and their combinations against rice blast disease. The nutrient combinations of potash (20g/L) and silicon (1g/L) resulted in disease incidence reductions of 79.38% and 78.76%, respectively, compared to the application of Nativo, which achieved slightly higher reductions of 82.38% and 80.76%. Among the zinc treatments and its combinations, zinc (2g/L) and silicon (1g/L) showed disease reductions of 72.39% and 73.4% in 2021 and 202, respectively. In 2019, the combination treatment of potash (20g/L) and silicon (1g/L) yielded the highest plant height (120.03 cm), number of tillers (23.01), panicle length (28.93 cm), and number of grains per panicle (128.19). In 2020, the same treatment resulted in the highest plant height (122.61 cm), number of tillers (17.23), panicle length (28.31 cm), and number of grains per panicle (122.61). The overall results of this study suggest that the application of alternative disease management strategies not only reduces the use of chemicals but also lowers the risk of residual effects on paddy grains, thereby enhancing the export potential of paddy.

Nuestro estudio pretende ser un granito más en el empeño historiográfico de la visibilización de las mujeres, de modo individual y colectivo, en la Historia de la Edad Moderna. Para ello analizamos las ventajas y limitaciones de la viudedad en una parte del Reino de Sevilla. Hemos tratado de cotejar el papel asignado a las viudas sujetas al ordenamiento legal castellano con la realidad espacial del Andévalo y parte de la Tierra Llana onubense.
La cronología elegida son los siglos XVI y XVII, Queremos indagar en las características específicas de los hogares encabezados por mujeres viudas, partiendo de su importancia cuantitativa. En una primera fase analizamos los mecanismos garantistas de la legislación y la práctica social que busca afianzar la supervivencia femenina, como la reversión de la dote y el usufructo vidual, con especial atención al derecho a residencia perpetua de la viuda en la casa del marido y a las mandas y mejoras condicionadas, que muestran las objeciones de muchos maridos a la hora de consentir las segundas nupcias de la viuda. 
La documentación notarial nos permite avanzar en el estudio de los mecanismos relativos a la asunción de la jefatura familiar. El uso de la plena capacidad legal les permite tener bajo su responsabilidad a hijos menores de edad, administrar los bienes y recursos familiares, solventar pleitos y negocios, desarrollar su labor tutelar y garantizar el casamiento de los hijos mediante el aporte de dote y arras proporcionadas que, además de avance de la legítima, son garantía de la emancipación de los hijos y de la constitución de nuevos hogares nucleares.
La viudedad femenina aparece como un fenómeno complejo, derivado de numerosas variables económicas, sociales y personales.

Cervantes VR or the possibility of including virtual reality in the teaching-learning process of Don Quixote
Authors: Calo Blanco Alba
Published: December 2024

In an already fully digitalised and virtualised world like the one we live in, innovation in education increasingly involves introducing ICT into the teaching-learning process. Thus, it could be said that some of the priority challenges facing our society are digital education and the development of digital skills. Virtual reality, perhaps our newest medium, is only just becoming established in our daily lives, and yet it already offers a wealth of options for teaching a wide range of disciplines.
This article aims to explore some of the possibilities of using virtual reality in the educational context, and more specifically in the field of language and literature teaching. To this end, the RTVE and Iralta VR Cervantes VRapp is presented as a case study. The aim of the app is to bring the life and work of Cervantes, and specifically his work Don Quixote, closer to the general public. It will be clear throughout these lines, therefore, how virtual reality is presented as a valuable resource for its use in active teaching methodologies such as gamification, and we will try to contribute to consolidate it as a possible effective teaching tool.

Published: December 2024

During the development of loose sandstone reservoirs, the issue of production decline and bottomhole pressure reduction caused by particle migration is widespread, directly impacting well productivity. Understanding the mechanism of particle migration in sandstone and determining the main factors affecting this process are crucial for improving oilfield development. This study focuses on an offshore oilfield and utilizes real digital core models constructed through CT scanning technology. Numerical simulations of fluid-solid coupling were conducted using Fluent and EDEM software to establish a coupled particle-oil-water flow model. This model was employed to investigate particle blockage modes and the effects of particle size, concentration, and injection rate on particle migration in the reservoir. The results indicate that particle migration primarily occurs in two blockage modes: pinhole blockage and bridging blockage. In sandstone, particle retention rates are primarily controlled by particle size, with larger pore-to-particle size ratios leading to higher retention rates. Particle concentration and injection rate have relatively minor effects on the final retention rate. As for migration distance, particle size significantly influences migration, with larger pore-to-particle size ratios resulting in shorter migration distances. Under low concentration conditions, concentration has a minimal effect on migration distance. However, as the injection rate increases, migration distance also increases. In summary, this study clarifies the particle migration mechanisms and the key factors controlling migration in sandstone formations, providing valuable theoretical support for oilfield development.

Published: December 2024

The most relevant intersections in society include the relationship between universities and companies for a projection toward the sustainable employability of future graduates. Among the possible intersections, Service-learning (SL) is an educational proposition that may help university students to develop their personal skills, offering them opportunities to learn and practice civic commitment, improving their sense of social and citizen responsibility, and combining academic and community-service learning in a constructed programme where participants train by working on real needs of the environment to optimize and transform the latter. The development of SL programmes in university departments related to technical areas is posing a challenge to faculty members and students, thus it is important to explore this lack of programmes. The main aim of the present study was to identify SL projects and their topics through a systematic review, following the guidelines of the «Preferred Reporting Items for Systematic Reviews and Meta-Analyses» (PRISMA) declaration in the knowledge areas of Architecture, Computer Science, Environmental Engineering, Software Engineering, Computer Engineering, Artificial Intelligence, and Computer Languages and Systems, from the year 2008 to the year 2023. This review includes 128 articles, which were analyzed with ATLAS. Ti 22. The categorical system employed in this work emerged from the topics of the programmes identified in the selected articles, which were verified by experts in the mentioned fields of knowledge. The agreed categories were: accessibility, learning, social groups, courses, devices, infrastructure, games, environment, landscaping, heritage, software and web. The most relevant conclusions highlight that most of the articles refer to theoretical aspects of SL, showing a lack of data on the practical development of SL programmes and their impact on employability. The largest number of SL programmes are developed in the areas of Architecture, Computer Science and Software Engineering. Regarding the topics that are addressed in research, most of the articles refer to social groups, software, learning and accessibility.
Feasibility of using nuclear microreactor process heat for bioconversion and agricultural processes
Authors: Pakkebier Jack , Skangos Christopher , Derby Melanie M.
Published: December 2024

Introduction

There is a global goal to reduce greenhouse gas emissions by 43% by 2023. Nuclear microreactors, a subset of small modular reactors, offer a potential solution due to their compact size, transportability, and carbon-neutral power generation capabilities.

Methods

This study explores the feasibility of using heat from nuclear microreactors for bioconversion and agricultural processes, including transforming biomass into energy carriers and products such as syngas, bio-oil, and pasteurized milk. Operating requirements for gasification, pyrolysis, hydrothermal carbonization, hydrothermal liquefaction, hydrothermal gasification, ethanol production, anaerobic digestion, and pasteurization were obtained through a literature review. A Brayton cycle model based on the eVinciTM microreactor was developed to assess the feasibility of powering these processes using nuclear microreactor heat.

Results and Discussion

Exergetic efficiency values for high-temperature processes ranged from 72% to 100%, whereas lower-temperature processes ranged from 2% to 53%. These efficiencies depend on the available source temperature for each microreactor design. There were trade-offs between producing net power and using process heat, particularly for high-temperature processes. Three heat exchanger locations were considered: before the turbine (600℃), between the turbine and regenerator (370℃), and after the regenerator (192℃). High-temperature processes like gasification require temperatures too high for feasibility. Middle temperature processes are better suited to a heat exchanger between the turbine and regenerator, while also operable before the turbine. Lower-temperature processes like pasteurization and anaerobic digestion can use waste heat after the regenerator and do not impact power production. These findings are valuable for optimizing nuclear microreactor heat use and aligning with global climate initiatives.

Understanding and monitoring sea surface salinity (SSS) and temperature (SST) is vital for assessing ocean health. Interconnections among the ocean, atmosphere, seabed, and land create a complex environment with diverse spatial and temporal scales. Climate change exacerbates marine heatwaves, eutrophication, and acidification, impacting biodiversity and coastal communities. Satellite-derived ocean colour data provides enhanced spatial coverage and resolution compared to traditional methods, enabling the estimation of SST and SSS. This study presents a methodology for extracting SST and SSS using machine learning algorithms trained with in-situ and multispectral satellite data. A global neural network model was developed, leveraging spectral bands and metadata to predict these parameters. The model incorporated Shapley values to evaluate feature importance, offering insight into the contributions of specific bands and environmental factors. The global model achieved an R2 of 0.83 for temperature and 0.65 for salinity. In the Gulf of Mexico case study, the model demonstrated a root mean square error (RMSE) of 0.83°C for test cases and 1.69°C for validation cases for SST, outperforming traditional methods in dynamic coastal environments. Feature importance analysis identified the critical roles of infrared bands in SST prediction and blue/green colour bands in SSS estimation. This approach addresses the “black box” nature of machine learning models by providing insights into the relative importance of spectral bands and metadata. Key factors such as solar azimuth angle and specific spectral bands were highlighted, demonstrating the potential of machine learning to enhance ocean property estimation, particularly in complex coastal regions.
Biomarkers and potential therapeutic targets driving progression of non-alcoholic steatohepatitis to hepatocellular carcinoma predicted through transcriptomic analysis
Authors: Fan Hui , Wang Rong , Wen Bin , Xiong Jing
Published: December 2024

Background

Non-alcoholic steatohepatitis (NASH) is the most prevalent chronic liver condition globally, with potential progression to cirrhosis, and even hepatocellular carcinoma (HCC). The increasing prevalence of NASH underscores the urgent need for advanced diagnostic and therapeutic strategies. Despite its widespread impact, effective treatments to prevent the progression of NASH remain elusive, highlighting the critical importance of innovative molecular techniques in both the diagnosis and management of this disease.

Methods

Six microarray datasets available in GEO were used to perform Robust Rank Aggregation (RRA) to identify differentially expressed genes (DEGs).We identified 62 robust upregulated genes and 24 robust downregulated genes. These genes were undergone Gene Ontology enrichment analysis and further examination for expression correlation with NAS score. Molecular subtypes were generated using “ConsensusClusterPlus” on identified genes, which were further assessed for tumor stage relevance, expression differences in adjacent and tumor tissues, and impact on survival in TCGA liver cancer patients. Single-cell analysis was then used to explore the genes across different cell types and subgroups as well as cell-type interactions. The clinical utility of predicted core genes was highlighted through decision curve analysis, with emphasis on HCC prognosis. The GDSC database was used to evaluate the relationship between the predicted core genes and drug sensitivity, while the TIDE database was used to evaluate their relationship with immunotherapy.

Results

Four core genes, TREM2, GDF15, TTC39A, and ANXA2, were identified as key to influencing HCC prognosis and therapy responsiveness, especially immune treatment efficacy in NASH-associated HCC.

Conclusion

The core genes may act as critical biomarkers driving the progression of NASH to HCC. They are potential novel targets for the diagnosis and treatment of NASH progression, offering innovative perspectives for its clinical management.

Introduction

Analytical essays are a fundamental discourse practice within educational settings. These essays are topic-oriented texts that aim to inform readers about a specific matter while persuading them of the writer's perspective. This study investigates how students' linguistic condition (monolingual vs. bilingual) affects their ability to meet the social and discursive expectations of analytical essays. This is examined both over a broad developmental span, from elementary to higher education, and microdevelopmentally, through a sequence of genre-oriented classroom activities.

Methods

A corpus of 1,179 essays, written by Spanish monolingual and Catalan/Spanish bilingual students across elementary, secondary, and university levels, was analyzed. Participants were tasked with producing texts on both same and different topics. The analysis focused on lexical, syntactic-discursive and structural features identified as indicators of writing proficiency in the Developing Analytical Writing (DAW) model developed in previous studies. Pedagogical input was controlled by the researchers, and an external evaluation of text quality was performed by teachers from the different school levels.

Results

Results indicate that students' linguistic condition influenced most, but not all, the linguistic and structural indicators of writing proficiency but always in interaction with age/school level and pedagogical input. Improvements were observed across school levels and with pedagogical input. Additionally, teachers varied in their appreciation of different facets of writing performance as a function of the participants' age/school level and pedagogical input. However, the linguistic condition of students alone did not significantly impact external evaluations of text quality.

Discussion

Our findings reveal a complex interplay between factors such as writers' linguistic condition, their age/school level, and pedagogical input, which jointly shape the quality of analytical essays.
Antarctic Sea ice distribution detection based on improved ant colony algorithm
Authors: Wang Xingdong , Sun Zehao
Published: December 2024

The changes in the Antarctic sea ice area are directly related to the changes in the atmosphere and oceans. Determining the Antarctic sea ice distribution is of great significance to the global climate change analysis. The ant colony algorithm adopts a positive feedback mechanism to continuously converge the search process and ultimately approaches the optimal solution, making it easy to find the optimal segmentation threshold for detecting the sea ice distribution. However, the ant colony algorithm has the problems of high computational complexity and easy getting stuck in local optima. In order to better apply the ant colony algorithm to sea ice distribution detection, an improved ant colony algorithm was proposed, which improves the selection of initial clustering centers and the update of pheromone volatilization factors in the ant colony algorithm. We compared the improved ant colony algorithm with iterative algorithm, maximum entropy algorithm, and basic global threshold algorithm, and the results showed that the proposed algorithm is feasible. To further validate the accuracy of the improved ant colony algorithm, we compared the results obtained from MODIS data with the improved ant colony algorithm, iterative algorithm, maximum entropy algorithm, and basic global threshold algorithm for sea ice detection, and the results showed that the accuracy of the proposed algorithm was 4.99%, 3.66%, and 5.46% higher than the other three algorithms, respectively.

Published: December 2024

Introduction

This study investigates rheological behavior and 3D printability of SBS-, CR-, SBS/CR-modified asphalt binder with C9 petroleum resin (C9PR) for crack filling.

Methods

Thirteen types of modified asphalt binders with respective C9PR of 0 wt%, 1 wt%, 2 wt%, 3 wt% were prepared and evaluated for their microstructure, physical properties, compatibility, rheological properties, and 3D printability.

Results

The results show that SBS, CR, and C9PR influenced significantly on rheological properties and 3D printability of modified asphalt binders. Physical blending and improved storage stability of modified asphalt binders were observed with the addition of C9PR. In addition, the combination of SBS and CR showed enhanced viscoelastic behavior and temperature sensitivity compared to the base asphalt binder due to the increased swelling behavior of SBS and CR in asphalt binders by C9PR.

Discussion

Asphalt binder with 3 wt% SBS, 15 wt% CR, and 1 wt% C9PR showed improved viscosity, elasticity, compatibility, high-temperature rutting resistance, and fatigue resistance. Additionally, C9PR expanded 3D printable temperature range of modified asphalt binder, leading to its potential use as an additive in 3D printed asphalt binders.

Published: December 2024

Introduction

The critical role of circular RNAs as non-coding RNAs in glioma has been extensively investigated. Therefore, we aimed to explore the role and potential molecular mechanisms of circRNA-mind bomb homolog 1 (circMIB1) in gliomas.

Methods

RNA sequencing was used to analyze the expression profiles of circRNAs in glioma tissues and normal brain tissues. Quantitative real-time polymerase chain reaction was implemented to examine the levels of circMIB1 in glioma cells and tissues. The circMIB1 was identified as a cyclic RNA molecule by DNA nucleic acid electrophoresis and ribonuclease R assay. The relationship between circMIB1 expression and the prognosis of glioma patients and its potential as a biomarker were analysed using Kaplan-Meier, Receiver operating characteristic curves, and Principal component analysis. Bioinformatics analysis predicted the miRNAs that bind to circMIB1 and their downstream targets, and analysed the functions of these genes.

Results

Firstly, a novel circRNA molecule termed circMIB1 was identified and validated by RNA sequencing. The expression of circMIB1 was significantly downregulated in glioma cells and tissues, and was closely associated with the tumor grade and survival prognosis of patients with glioma. Hence, it may be useful as a biomarker for glioma. Secondly, it was predicted that circMIB1 binds to hsa-miR-1290 based on bioinformatics analysis, which was significantly upregulated in glioma cells and tissues, and correlated with the tumor grade and overall survival of patients. Thirdly, through a series of bioinformatics analyses identified six genes downstream of hsa-miR-1290 that were significantly associated with glioma expression and prognosis, these genes are associated with cell cycle, cell necrosis and cell circadian rhythms.

Discussion

CircMIB1 may play a role in inhibiting glioma development through the hsa-miR-1290 competitive endogenous RNA interaction network, these findings provide new ideas and directions for the diagnosis and treatment of glioma.
