Preservation and reactivation strategies for quorum quenching media to combat membrane biofouling

Microbial quorum quenching (QQ), which addresses biofouling resistant to physical and chemical methods, presents a compelling solution. Enhancements in sustainability are imperative to ensure its long-term stability. This study explores QQ media preservation for extended use. Three media types were tested over 150 days: fresh BH4 cells, preserved/reactivated BH4 cells, and BH4 cell extracts. Initial QQ activities ranged in the appropriate levels from 1.08 to 1.24 h−1. Preservation in 50 mM Tris-HCl at 4 °C showed that media with whole cells retained approximately 60 % activity after 60 days, unlike cell extract media, which lost all activity. However, the dehydration and reactivation of BH4 cell media fully recovered the initial QQ activity while maintaining it for 150 days. In MBR tests, reactivated QQ media performed as effectively as those prepared with freshly cultured BH4 cells, delaying membrane fouling by 2-fold. Revitalizing QQ media in combination with chlorine-based chemically enhanced backwashing (CEB) further delayed fouling by 2.5 times compared to CEB alone. Reactivated QQ media retained robust activity even after prolonged MBR use. This study showcases the effectiveness of dehydration and reactivation techniques for preserving QQ media, ensuring its reliable long-term storage and utilization. However, further enhancements are necessary to optimize cell viability.

Light-Emitting Diodes and Liquid System Affect the Caffeoylquinic Acid Derivative and Flavonoid Production and Shoot Growth of Rhaponticum carthamoides (Willd.) Iljin.

Plant in vitro cultures can be an effective tool in obtaining desired specialized metabolites. The purpose of this study was to evaluate the effect of light-emitting diodes (LEDs) on phenolic compounds in Rhaponticum carthamoides shoots cultured in vitro. R. carthamoides is an endemic and medicinal plant at risk of extinction due to the massive harvesting of its roots and rhizomes from the natural environment. The shoots were cultured on an agar-solidified and liquid-agitated Murashige and Skoog's medium supplemented with 0.1 mg/L of indole-3-acetic acid (IAA) and 0.5 mg/L of 6-benzyladenine (BA). The effect of the medium and different treatments of LED lights (blue (BL), red (RL), white (WL), and a combination of red and blue (R:BL; 7:3)) on R. carthamoides shoot growth and its biosynthetic potential was observed. Medium type and the duration of LED light exposure did not affect the proliferation rate of shoots, but they altered the shoot morphology and specialized metabolite accumulation. The liquid medium and BL light were the most beneficial for the caffeoylquinic acid derivatives (CQAs) production, shoot growth, and biomass increment. The liquid medium and BL light enhanced the content of the sum of all identified CQAs (6 mg/g DW) about three-fold compared to WL light and control, fluorescent lamps. HPLC-UV analysis confirmed that chlorogenic acid (5-CQA) was the primary compound in shoot extracts regardless of the type of culture and the light conditions (1.19-3.25 mg/g DW), with the highest level under R:BL light. BL and RL lights were equally effective. The abundant component was also 3,5-di-O-caffeoylquinic acid, accompanied by 4,5-di-O-caffeoylquinic acid, a tentatively identified dicaffeoylquinic acid derivative, and a tricaffeoylquinic acid derivative 2, the contents of which depended on the LED light conditions.

Occurrence of microplastics in the Haima cold seep area of the South China Sea

The pollution of deep-sea microplastics has received increasing attention. As a special ecosystem in the deep sea, the cold seep area is of great significance for studying the distribution of microplastics in the deep sea. In this work, the distribution and characteristics of microplastics in seawater, sediments, and shellfish in the Haima cold seep area and the correlation between the characteristics of microplastics in different media and the type of media were studied. Microplastics were found in all three media. The abundance of microplastics in different samples from the Haima cold seep area ranged 1.8–3.8 items/L for the seawater, 11.47–96.8 items/kg (d.w.) for the surface sediments, and 0–5 items/individual (0–0.714 items/g) for the shellfish. The amount of microplastics ingested by shellfish varied among different species. The microplastics in these three media were mainly fibrous, dark-colored, small-sized rayon, polyethylene terephthalate (PET), and polyethylene (PE). In the correlation analysis of microplastic characteristics among the three media, it was found that the characteristics of microplastics in different media in the same area were closely related, and each pair of variables showed a significant positive correlation (P ≤ 0.05). The distinctive geographical conditions would accelerate the interchange of microplastics among various media. Principal component analysis showed that habitat contribute to microplastic feature differences in shellfish. Differences in correlation were observed between the characteristics of shellfish microplastics in different regions and the characteristics of microplastics in surrounding seawater and sediments.

Probing black hole in Starobinsky-Bel-Robinson gravity with thermodynamical analysis, effective force and gravitational weak lensing

In this work, we investigate the effects of plasma and the coupling parameter β>0, on the thermodynamic properties and weak gravitational lensing by the Schwarzschild-like black hole in the Starobinsky-Bel-Robinson gravity (SBRG). We observe that the horizon radius and the corrected entropy of the Schwarzschild-like black hole in the SBRG are not much sensitive to the parameter β. On contrary the energy emission rate of the Schwarzschild-like black hole in the SBRG is sensitive to the parameter β and decreases with increase in the values of the parameter β. We see that the Schwarzschild-like black hoe in the SBRG is stable as the thermodynamicl temperature is positive for different values of the parameter β. Moreover we observe that the deflection angle of photon beam by the black hole in uniform plasma, nonuniform self-interacting scalar plasma and non-singular isothermal gas sphere reduces with the parameter β, against the impact parameter b. We see that the deflection angle enhances with increase in the concentration of the plasma fields for all the three types of plasma media. Further we find that the magnification of the image due to lensing increases in a higher concentration of plasma field. It is interesting to notice that the image magnification in uniform plasma is much higher as compared to the one in nonuniform plasma field. We compare our results with those for the Schwarzschild black hole of General Relativity. Further, effective force is also calculated for the Schwarzschild-like black hole in the SBRG.

Influence of plasma on the optical appearance of spinning black hole in Kalb-Ramond gravity and its Existence around M87* and Sgr A*

The visible universe is filled with different types of plasma media in the form of stars, nebulas and other forms of excited gases. These matter fields have a high influence on the gravity and are likely to be present around the black holes due to the immense gravitational attraction. Since a plasma medium affects the speed of light, therefore we investigated the null geodesics and various optical features around the rotating black hole in Kalb-Ramond gravity immersed in plasma medium. Various plasma distributions are considered to develop a comparative study for their influence on unstable null circular orbits, shadows and evaporation rate of the black hole in the presence of a plasma medium. Moreover, the shadow results are also compared with Event Horizon Telescope data for M78* and Sgr A* in order to estimate the parametric bounds for which the rotating black hole in Kalb-Ramond gravity is considered either M87* or Sgr A* under the different values of plasma parameters. From this analysis, we also found the distribution of plasma that has a significant impact on the above mentioned features and is most likely to be present around M87* and Sgr A*.

Autobiographical phenomenology of memories of fiction

ABSTRACT Most autobiographical memories are based on real-life experiences, but memories of fiction have many similarities to real-life autobiographical memories. However, the phenomenological nature of this similarity, the potential differences between media types, and the role of individual differences need further investigation. Based on previous findings, we expected differences between media types on emotional intensity, sensory vividness, and confidence about the recall. To provide insight into these issues, we collected one real-life autobiographical memory and one memory of fiction (book, film, or video game) from 291 participants. We asked them to rate their memories phenomenologically. The participants also provided information regarding their motivations for engaging with fictional stories. Our results show phenomenological differences in several dimensions between media types and differences in the similarity of media types to real-life memories. While absorption seems to be a good predictor for immersion, escapism tendency is a motivation to engage with fiction frequently.

A Study on the Development of the Educational Materials of the 〈General Korean Language〉 for International Undergraduate Students inan Intermediate Level of the Korean Language

This is a basic study to develop the educational materials for general Korean language learning for international undergraduate students in the intermediate level. It aims to survey the needs of learners and thereby establish some developmental directions. To achieve this, Iconducted a survey with 306 international students at A University. The results showed that many learners recognized the necessity of textbook development, and that although there was a high preference for e-books, ademand for paper books still existed. Regarding preferred media types, demands were observed not only for familiar media such as movies, dramas and social media, but also for other types of media like newspaper articles and the news in general. Regarding the topics demanded, they included daily life, hobbies, personalities, travel, and social and academic subjects. As for the desired functions to be enhanced, there were high demands for speaking, vocabulary, and grammar, and the balanced demands for listening, reading, and writing. Accordingly, this study proposed that educational materials should be composed in such a way that e-books and paper books coexist, and that the materials should be developed by maximizing the educational value of each. Furthermore, this study suggested that a comprehensive textbook that develops all language functions evenly would be more suitable than educational materials specialized in one function, given the characteristics of learners who need to not only expand their learning experiences with the use of various media, but to also cultivate their communication skills and academic task performance abilities.

Stability, Thermophysical, Optical and Photothermal Properties of ZnO Nanofluids with Added Anionic/Cationic Mixed Surfactants

Abstract Metal oxide nanofluid is a new type of heat transfer medium with good thermal performance, which can be used to improve the heat collection and photothermal conversion performance of the collector. The development of new nanofluids with excellent stability, thermophysical and photothermal properties is very important for solar thermal utilization. In this paper, the ZnO nanofluids with SDS/CTAB mixed surfactants were prepared by two-step method. Their stability, thermophysical, optical and photothermal properties were studied based on experimental data. Then, the optimum concentration and preparation conditions of the proposed ZnO nanofluid adding SDS/CTAB with good photothermal performance were obtained. The results showed that the ZnO nanofluid adding SDS/CTAB mixed surfactants has good dispersion stability and thermal physical properties with thermal conductivity up to 0.772 W/(m·K). Moreover, it has the lowest transmittance of 0.10% and the highest extinction coefficient of 7.25 cm-1. Moreover, the addition of SDS/CTAB mixed surfactants makes ZnO nanofluids show better photothermal conversion efficiency, up to 87%. Therefore, ZnO nanofluids with SDS/CTAB added have great potential as working fluids for DASC.

Research on the Transformation and Upgrading of News Media based on the Internet of Things era

The rise of the so-called "Internet of Things" heralds the arrival of innovative improvements in the dissemination technologies that are the basis for the development and improvement of a wide variety of forms of media. It has gone a long way from the early days of digitization and networking, and now it even incorporates intelligence. In the past, it did not have this capability. The widespread adoption of technology based on the Internet of Things will lead to profound shifts in the efficiency of media communication, as well as the transformation and upgrading of communication intelligence, the explosive growth of the communication platform, the emergence of a high degree of integration between "content production" and new communication techniques, and other developments related to these trends. It is generally agreed upon that the Internet of Things will be the primary impetus behind the next age of information technology as well as the expansion of the global economy. It is communicative, modular, and organized when it comes to the transmission of information. The ever-expanding media sector won't be a problem for this roomy facility. People's perspectives on the function of the media will shift as a result of the Internet of Things since it will make it feasible to intelligently update various types of media that are already in existence. Consumers will have access to a broad range of data presented in a number of formats as a direct consequence of the Internet of Things. It is feasible to expand the media applications of the Internet of Things by concentrating on one of these three areas: the development of a new media service system; the production of new media content; or the undertaking of a new media life challenge. This article examines the deconstruction of the primary body of dissemination pertaining to the Internet of Things from five distinct vantage points. Topics covered include the Internet of Things' news dissemination materials as well as dissemination objects. There are a number of different ways in which the framework of news dissemination may be made more effective, including bringing it up to date, enhancing its function, improving its platforms, fortifying its content, and increasing the breadth of its coverage. In terms of rebuilding and reconstruction, talk about the positive and constructive functions that modern information technology plays in the news broadcasting industry. In addition, the purpose of this article is to investigate the impact that the Internet of Things has on the method by which news is disseminated and the media business as a whole, as well as the relationship that exists between the social application of IoT technology and the news media. This article will hopefully widen the breadth of usage for internet of things technology in the news distribution sector by investigating a variety of different techniques. It is anticipated that in addition to accomplishing this goal, this work will also contribute to the proliferation of conventional media.

Redefining the Communication Dynamics in Bolsonaro’s Brazil: Media Consumption and Political Preferences

In this article, we contend that understanding Brazil’s current communicative landscape requires a closer examination of the relevance of legacy media outlets, challenging the widely accepted “traditional media bypass” thesis, which posits that social media platforms have overtaken traditional media as the primary influencers of political discourse, an argument often used to explain the rise of extreme-right ideologies across different national contexts. In order to test the association between voting preferences and the use of different types of media, we employ logistic regression analysis using data from a recent survey that includes numerous questions about the information and media consumption habits of Brazilian voters. Our findings highlight that legacy media, particularly broadcast TV channels like Globo, Record, and SBT, remain dominant in Brazil as sources of political information. Contrary to the bypass thesis, Bolsonaro’s supporters, while favoring social media, also consume significant amounts of legacy media. Analysis reveals stark differences in media preferences between the supporters of different political candidates, challenging the notion of an exclusive reliance on social media by right-wing supporters. The data also indicate nuanced media consumption habits, such as a preference for certain TV channels and fact-checking behaviors, underscoring the complex interplay between legacy and social media.

Strategies for Using Learning Media in Islamic Religious Education Subjects

Islamic Religious Education (IRE) is an important subject for every student to learn. Islamic Education learning can be organized by utilizing various types of learning media, as has been implemented in Madrasah Tsanawiyah Miftahul Ulum Wonokoyo, East Java, where Islamic Education learning involves the use of print media and audio-visual media as learning tools. The purpose of this study is to examine the strategy of using learning media in IRE subjects at Madrasah Tsnawiyah Miftahul Ulum Wonokoyo. The research method used in this study is descriptive qualitative method. Data were collected through literature study, observation, and interviews with three Islamic teachers at the MTs. The collected data were analyzed through three stages, namely data reduction, data presentation, and conclusion drawing. The results showed that the management of the use of learning media in IRE subjects at Madrasah Tsanawiyah Miftahul Ulum Wonokoyo is still weak. This is caused by several factors, namely the lack of support from the madrasah for the procurement of IRE learning media and the lack of willingness of IRE teachers to improve their competence in the use of learning media. Efforts to improve the management of the use of learning media in IRE subjects at Madrasah Tsanawiyah Miftahul Ulum Wonokoyo require some management improvements in aspects such as the curriculum that can support the effective use of learning media, the role of teachers to improve their competence in the use of learning media, learning methods and learning media.

Biodegradation Study of Styrene-Butadiene Composites with Incorporated Arthrospira platensis Biomass.

The preparation of polymer composites that incorporate material of a biogenic nature in the polymer matrices may lead to a reduction in fossil polymer consumption and a potentially higher biodegradability. Furthermore, microalgae biomass as biogenic filler has the advantage of fast growth and high tolerance to different types of culture media with higher production yields than those provided by the biomass of terrestrial crops. On the other hand, algal biomass can be a secondary product in wastewater treatment processes. For the present study, an SBS polymer composite (SBSC) containing 25% (w/w) copolymer SBS1 (linear copolymer: 30% styrene and 70% butadiene), 50% (w/w) copolymer SBS2 (linear copolymer: 40% styrene and 60% butadiene), and 25% (w/w) paraffin oil was prepared. Arthrospira platensis biomass (moisture content 6.0 ± 0.5%) was incorporated into the SBSC in 5, 10, 20, and 30% (w/w) ratios to obtain polymer composites with spirulina biomass. For the biodegradation studies, the ISO 14855-1:2012(E) standard was applied, with slight changes, as per the specificity of our experiments. The degradation of the studied materials was followed by quantitatively monitoring the CO2 resulting from the degradation process and captured by absorption in NaOH solution 0.5 mol/L. The structural and morphological changes induced by the industrial composting test on the materials were followed by physical-mechanical, FTIR, SEM, and DSC analysis. The obtained results were compared to create a picture of the material transformation during the composting period. Thus, the collected data indicate two biodegradation processes, of the polymer and the biomass, which take place at the same time at different rates, which influence each other. On the other hand, it is found that the material becomes less ordered, with a sponge-like morphology; the increase in the percentage of biomass leads to an advanced degree of degradation of the material. The FTIR analysis data suggest the possibility of the formation of peptide bonds between the aromatic nuclei in the styrene block and the molecular residues resulting from biomass biodegradation. It seems that in industrial composting conditions, the area of the polystyrene blocks from the SBS-based composite is preferentially transformed in the process.

Why are social media users susceptible to health misinformation? A perspective from complexity theory

PurposeHealth misinformation on social media threatens public health. A critical question that sheds light on the propagation of health misinformation across social media platforms revolves around identifying the specific types of social media users susceptible to this issue. This study provides an initial insight into this matter by examining the underlying psychological mechanism that renders users susceptible to health misinformation.Design/methodology/approachIn this study, we developed an integrated model of susceptibility to health misinformation, drawing on the motivation-opportunity-ability theory and the elaboration likelihood model. We collected the data from a sample of 342 social media users in China. Furthermore, the fuzzy-set qualitative comparative analysis was adopted to examine the proposed model and uncover the causal recipes associated with susceptibility to health misinformation.FindingsThe results indicated that there are three configural types of users that are susceptible to health misinformation: the health-consciousness core-driven type, the popularity-driven core type and the dual-driven type characterized by both high health consciousness and information popularity. Among these, high health-consciousness and the reliance on information popularity-based pathways emerge as pivotal factors influencing susceptibility to health misinformation.Originality/valueThis study contributes to the social media literature by identifying various psychological traits that lead to social media users’ susceptibility to health misinformation. Additionally, the study provides comprehensive guidance on how to mitigate the spread of health misinformation.

Forecasting Gas Well Classification Based on a Two-Dimensional Convolutional Neural Network Deep Learning Model

In response to the limitations of existing evaluation methods for gas well types in tight sandstone gas reservoirs, characterized by low indicator dimensions and a reliance on traditional methods with low prediction accuracy, therefore, a novel approach based on a two-dimensional convolutional neural network (2D-CNN) is proposed for predicting gas well types. First, gas well features are hierarchically selected using variance filtering, correlation coefficients, and the XGBoost algorithm. Then, gas well types are determined via spectral clustering, with each gas well labeled accordingly. Finally, the selected features are inputted, and classification labels are outputted into the 2D-CNN, where convolutional layers extract features of gas well indicators, and the pooling layer, which, trained by the backpropagation of CNN, performs secondary dimensionality reduction. A 2D-CNN gas well classification prediction model is constructed, and the softmax function is employed to determine well classifications. This methodology is applied to a specific tight gas reservoir. The study findings indicate the following: (1) Via two rounds of feature selection using the new algorithm, the number of gas well indicator dimensions is reduced from 29 to 15, thereby reducing the computational complexity of the model. (2) Gas wells are categorized into high, medium, and low types, addressing a deep learning multi-class prediction problem. (3) The new method achieves an accuracy of 0.99 and a loss value of 0.03, outperforming BP neural networks, XGBoost, LightGBM, long short-term memory networks (LSTMs), and one-dimensional convolutional neural networks (1D-CNNs). Overall, this innovative approach demonstrates superior efficacy in predicting gas well types, which is particularly valuable for tight sandstone gas reservoirs.
