Removal of pharmaceutical compounds and toxicology study in wastewater using Malaysian fungal Ganoderma lucidum

Elevated usage of pharmaceutical products leads to the accumulation of emerging contaminants in sewage. In the current work, Ganoderma lucidum (GL) was used to remove pharmaceutical compounds (PCs), proposed as a tertiary method in sewage treatment plants (STPs). The PCs consisted of a group of painkillers (ketoprofen, diclofenac, and dexamethasone), psychiatrists (carbamazepine, venlafaxine, and citalopram), beta-blockers (atenolol, metoprolol, and propranolol), and anti-hypertensives (losartan and valsartan). The performance of 800 mL of synthetic water, effluent STP, and hospital wastewater (HWW) was evaluated. Parameters, including treatment time, inoculum volume, and mechanical agitation speed, have been tested. The toxicity of the GL after treatment is being studied based on exposure levels to zebrafish embryos (ZFET) and the morphology of the GL has been observed via Field Emission Scanning Electron Microscopy (FESEM). The findings conclude that GL can reduce PCs from <10% to >90%. Diclofenac and valsartan are the highest (>90%) in the synthetic model, while citalopram and propranolol (>80%) are in the real wastewater. GL effectively removed pollutants in 48 h, 1% of the inoculum volume, and 50 rpm. The ZFET showed GL is non-toxic (LC50 is 209.95 mg/mL). In the morphology observation, pellets GL do not show major differences after treatment, showing potential to be used for a longer treatment time and to be re-useable in the system. GL offers advantages to removing PCs in water due to their non-specific extracellular enzymes that allow for the biodegradation of PCs and indicates a good potential in real-world applications as a favourable alternative treatment.

한국제품 데이터기반의 소비자제품 정량적 리스크평가방법연구

The purpose of this study is to contribute to enhancing consumer safety by researching a quantitative product risk assessment method that allows for annual monitoring of product hazards. The study proposes a method for conducting rapid and straightforward evaluations annually using accident data from the Korea Consumer Agency, product usage survey data, and resident population data. Based on the number of accidents, usage rates, and population, probabilities of occurrences were derived, and severity was calculated based on injuries and affected body parts to perform quantitative evaluations. As a result of the research, 262 consumer products were evaluated using the proposed method, identifying 12 products with severe risk ratings, 6 products with increased risk, and 11 products with decreased risk annually. These evaluation results have the significant advantage of being able to observe changes in product hazards annually. They can be utilized not only for enhancing safety, easing regulations, and consumer education policy formulation but also as foundational data for various sectors including consumers, parents, children, and educators, thereby contributing to raising awareness and policy formulation regarding domestic consumer safety.

'SIMLA' Educational Game-Based Learning Media for the Inculcation of Pancasila Symbols and Principles, Augmenting Independent Character

The transition from the K13 curriculum to an independent curriculum creates problems, especially in the learning process and learning media. A learning process needs to be supported by good learning media to achieve learning goals. This research aims to develop the educational game learning media "SIMLA" with material on the symbols and principles of Pancasila to strengthen the independent character of fourth-grade elementary school students. The type of research used is the research and development (R&amp;D) ADDIE development model. The research subjects were material experts, media, teachers, and fourth-grade elementary school students. Data collection includes interview guides, validation instruments, and student questionnaires. This quantitative data was obtained from material, media, user/teacher, and student validator questionnaires. Qualitative data was obtained from suggestions and input from experts, users, and students. The validator analysis technique uses a Likert Scale. Data obtained from product trials and usage tests uses the Guttman scale. The results obtained from material validation were 87.5% (very valid), media validation 93.75% (very valid), user validation 100% (very valid), and product trials 100% (very practical/interesting). It is practical and fun to improve independent character. The results of the paired t-test show that this product is very effective in improving students' abilities. The educational game learning media produced using the Construct 3 application is valid and can improve student learning outcomes.

Quantifying food consumption supply risk: An analysis across countries and agricultural products

Resource criticality is the field of study that quantifies supply risks for a set of resources. To assess the vulnerability of a country's food supply, whether domestically produced or imported, supply risk indexes for agricultural products have been developed by adapting a resource criticality method and a supply diversity model. These indexes take into account both the diversity of supply and the risks to which each sourcing option is exposed, such as climate or price volatility.The results enable a comparison of the supply risk of food consumption between different countries and identification of the products with the highest risk of supply disruption for each country. When analysed by region, the results indicate that North America and Europe generally have lower supply risk across all products than the rest of the world, while African and Sub-Saharan countries tend to have the highest supply risk. Furthermore, the analysis of supply risks for four cereals - wheat, maize, rice, and sorghum - indicates that trade diversification can reduce supply risks for wheat and maize in many countries. However, for rice and sorghum, supply risk reduction will most likely be achieved through stockpiling, export redirection, and adaptation of agriculture to climate change. The results highlight the importance of supply risk indexes for decision-making, particularly when compared to self-sufficiency. Finally, limitations and new perspectives are discussed, including the need to adapt the index to nutritional data, consider competition for agricultural product usage, and refine climate or economic risk indexes.

High-efficiency thermal reduction of CO2 to high-valued carbon nanotubes

To reduce the amount of carbon dioxide (CO2) already emitted into the atmosphere, various carbon capture, utilization, and storage (CCUS) technologies have been developed for climate and economic reasons in recent years. However, the state of art CCUS techniques suffer from deficiencies such as high cost, low yield, and harsh and discontinuous production conditions. In this work, we report a new thermal reduction method for continuously conversing CO2 to methane (CH4) by introducing sodium borohydride (NaBH4) as a reductant under catalyst-free conditions. Experimental results show that CO2 can be fully captured and converted to CH4 and carbon monoxide (CO) and the selectivity efficiency of CO2 to CH4 can be achieved to be as high as 90% with the optimization of experimental conditions. Such a result originates from the high activity of NaBH4 and high selectivity of the thermal reduction of CO2. To demonstrate one of the potential usages of the reduction products, we integrated the thermal reduction of CO2 with the production of carbon nanotubes (CNTs). As long as CO2 is supplied at the source end, the reduction products can undergo catalytic decomposition to produce a CNT fiber or film continuously at the final end. The present technique is featured with simple equipment setup, low cost, and continuous thermal reduction, thus providing a new pathway for the large-scale conversion of CO2 into high-valued products for wide applications.

Showing usage behavior or not? The effect of virtual influencers’ product usage behavior on consumers

With the development of technology and the low cost of creation, virtual influencers have become increasingly common and interact deeply with consumers in ‘human ways’, such as demonstrating or using products. There has been limited research on the effect of virtual influencers' behavioral realism on consumers, specifically through the lens of experiencing products vicariously. With the aim of exploring how virtual influencers' product usage behavior affects consumers, our study involved three online experiments and a secondary data analysis. The results show that the presence (vs. absence) of virtual influencer's product usage behavior significantly triggers perceptions of greater competence in virtual influencers and ultimately elicits more positive reactions from consumers; however, this effect diminishes with anime-like virtual influencers or the presence of content that explains the algorithms behind the recommendations. Our paper provides empirical evidence and extends research on behavioral realism of virtual influencers. These findings suggest marketers can strengthen consumer engagement by applying strategies that mimic human behavior, such as showing product usage behavior. However, it is important to exercise caution in the selection of virtual influencer types and in determining the extent to which explanations about the algorithms are provided.

Fostering self-efficacy through usability and emotional product design? An explorative study

Raising the user’s self-confidence is a promising strategy to reduce product-related user stigma. In the context of product usage, the commonly used term self-confidence refers to the psychological construct of self-efficacy. To strengthen a user’s self-efficacy through product design, providing both good usability and emotionality in a product seems to be a reasonable starting point. However, their suitability and validity for this purpose has not yet been sufficiently assessed. This paper examines whether self-efficacy would be associated with perceptions of a product’s usability and emotionality. By conducting an online survey (n = 105; stigma-sensitive product demonstrator: walker), it was confirmed that the perception of good usability and emotionality of walkers were positively associated with the user’s perceived self-efficacy. Moreover, a negative interaction effect was identified showing that the association between emotionality and self-efficacy increased with lower levels of perceived usability and vice versa. This may indicate that emotions can compensate the importance of usability at least to some extent.

Evaluating the Credibility and Reliability of Online Information on Cannabidiol (CBD) for Epilepsy Treatment in Poland.

The interest in the potential therapeutic use of cannabis, especially cannabidiol (CBD), has increased significantly in recent years. On the Internet, users can find lots of articles devoted to its medical features such as reducing seizure activity in epilepsy. The aim of our work was to evaluate the information contained on the websites, including social media, in terms of the credibility and the reliability of current knowledge about the usage of products containing cannabidiol in epilepsy treatment. We used online available links found using the Newspointtool. The initial database included 38,367 texts, but after applying the inclusion and exclusion criteria, 314 texts were taken into consideration. Analysis was performed using the DISCERN scale and the set of questions created by the authors. In the final assessment, we observed that most of the texts (58.9%) were characterized by a very poor level of reliability and the average DISCERN score was 26.97 points. Additionally, considering the form of the text, the highest average score (35.73) came from entries on blog portals, whereas the lowest average score (18.33) came from comments and online discussion forums. Moreover, most of the texts do not contain key information regarding the indications, safety, desired effects, and side effects of CBD therapy. The study highlights the need for healthcare professionals to guide patients towards reliable sources of information and cautions against the use of unverified online materials, especially as the only FDA-approved CBD medication, Epidiolex, differs significantly from over-the-counter CBD products.

Luxury brand at the cusp of lipstick effects: Turning brand selfies into luxury brand curruncy to thrive via richcession

A fear of a richcession is on the horizon. The luxury industry must rekindle customer desires and promote brand selfies in order to survive. The narcissist and materialist affluent people upload their selfies along with luxury brand signatures, and this triggers the self-inferential process in the fellow affluent and shapes their luxury preferences. This study investigates this phenomenon, the lipstick effect, and its connection with richcession. A niche group of ultra-rich affluent people was chosen based on their spending patterns, their access to famous personalities, their choice of expensive places, their usage of luxury products, and their postings of selfies with luxury signatures. The study developed a measurement scale via a three-step survey-based approach by analyzing 468 questionnaires. The confirmatory factor analysis (CFA) proposes 27 items of a new scale. The structural analysis was then conducted in order to ensure the scale validity and stability by employing a new dataset of 356 questionnaires. We demonstrated how luxury brand selfies influence luxury signature, and how this in turn affects luxury brand currency and preference.

Regimes of global and national oil palm cultivations from 2001 to 2018

Oil palm is the dominant global oil crop due to its high productivity and diversified usage in many sectors. Since the late 20th century, oil palm cultivations proliferated in Southeast Asia, West Africa, and Latin America. However, global market factors, different national and regional policies, and smallholder versus commercial planting regimes in different areas lead to significant differences in economic benefits and environmental problems from deforestation and loss of biodiversity. We investigated changes in global and national distributions against suitability and indices of tree age distribution change for industrial oil palm (IOP) and smallholder oil palm (SOP). Spatial and temporal change analyses show that: i) For most tree ages, the proportion of global oil palm planting in suitable areas was less than 50%, but the impact of temporal regimes, from possible market factors and local policies, on planting structure should not be neglected; ii) Central America, South America, and West Africa were less suitable for oil palm cultivation compared to Southeast Asia. While, as two dominant oil palm planting countries, Indonesia and Malaysia had relatively low planting suitability, with 39.23% of Indonesia’s IOP, 44.85% of Indonesia’s SOP, 30.90% of Malaysia’s IOP and 18.77% of Malaysia’s SOP in highly and most suitable intervals; iii) There exist clear differences between IOP and SOP in terms of suitability, planting structure and spatial expansion patterns; iv) Hysteresis effect exists between latecomers (countries in West Africa and Latin America) and forerunner (Indonesia and Malaysia) in terms of spatial expansion; v) The spatial expansion patterns of oil palm planting centers have obvious scale effects for both IOP and SOP, with clear inter-country and intra-country differences. This paper reinterprets the global distribution of tree age and spatial expansion pattern and recommends scientific strategies to guide site selection and planting structure that enable oil palm cultivation for sustainable development.

Understanding the behavioural drivers of mindful consumption: a study on the use of sustainable menstrual products

PurposeThe adverse environmental impacts of menstrual products are a significant concern because of their widespread use and non-biodegradability. With various global and regional initiatives on sustainability, there is now greater public awareness about environmental protection. This heightened awareness has resulted in the exploration of alternative methods to reduce waste, such as the development and use of sustainable menstrual products. This study aims to examine the factors that influence Indian women’s purchasing intention in relation to sustainable menstrual products. The study uses the Stimulus–Organism–Behavior–Consequence (SOBC) theory as the appropriate grounded theory to explain these determinants.Design/methodology/approachCross-sectional data were collected from 720 women who have been using sustainable menstrual products. For analysing the model, the study performed structural equation modelling using AMOS.FindingsThe study’s results indicated that health consciousness, sustainability knowledge and environmental responsibility are positively associated with self-identity and mindfulness. Additionally, the study found that organism states have a positive impact on the purchase intention of sustainable menstrual products. Furthermore, there was a significant relationship observed between purchase intention and mindful consumption. The study also discovered significant positive relationships between satisfaction and key associations.Originality/valueThis study may be considered pioneering, as it establishes a connection between the usage of sustainable menstrual products and concepts such as mindfulness and mindful consumption.

Energy-constrained production optimization for the in-situ conversion process of oil shale based on deep learning algorithms

The in-situ conversion process (ICP) involves complicated thermal-reactive-compositional flow processes where the production parameters are closely interdependent. Therefore, manual optimization of the production parameters of ICP through numerical simulation is arduous and time-consuming. This paper introduces a computational framework that integrates deep learning techniques and particle swarm optimization (PSO) to automatically optimize the values of production parameters of ICP, and thus locating the highest energy efficiency and the optimum energy usage. This approach utilizes a 3D CNN model to predict key metrics. The prediction process considers the detailed 3D heterogeneity of oil shale, resulting in remarkably high prediction accuracy, as evidenced by determination coefficients (R2) above 0.99. Subsequently, the trained CNN model is integrated to the PSO algorithm to automatically fine-tune the production parameters to optimize the energy efficiency of ICP.The optimization results yield three significant findings. First, as the energy consumption limit increases, the optimal number of heaters, well spacing, and heating temperature exhibit an upward trend, but stabilized beyond the threshold of 7 × 105 kWh. Secondly, the optimal input energy (7 × 105 kWh) is found for the given ICP model. Lastly, the analysis reveals that variations in initial reservoir pressure or bottomhole pressure have limited impact on cumulative oil production and energy usage.

An exploratory, randomised, crossover study to investigate the effect of nicotine on cognitive function in healthy adult smokers who use an electronic cigarette after a period of smoking abstinence

BackgroundAs well as being associated with serious negative health outcomes, smoking has been reported to have an array of physiological and psychological effects, including effects on mood and cognitive function. Post-cessation, loss of such effects (including temporary deficits in cognitive function) have been cited as reasons for resumption of smoking. The effects of e-cigarettes and nicotine delivered by e-cigarettes on these functions have not been widely researched but may play a role in the effectiveness of e-cigarettes as a satisfactory alternative to combustible cigarettes for people who smoke, and in encouraging individuals who would otherwise continue to smoke, to transition to e-cigarettes.MethodsThe study was an exploratory, randomised, partially-blinded, single-centre, five-arm crossover trial that recruited 40 healthy male and female people who smoke. At 5 study sessions, following a 12-h period of nicotine abstinence, participants were randomly assigned to use either a combustible cigarette, an e-cigarette of three varying nicotine strengths (18 mg/mL, 12 mg/mL or 0 mg/mL respectively) or observe a no product usage session. Participants completed pre- and post-product usage assessments to examine the product usage effect on cognitive performance (using the Cambridge Neuropsychological Test Automated Battery (CANTAB)), subjective mood and smoking urges.ResultsA significant improvement in sustained attention task performance was observed following use of both the nicotine containing e-cigarettes and combustible cigarette compared to no product use. Additionally, there were no significant differences between the nicotine containing products, indicating that nicotine use enhanced sustained attention regardless of delivery format. Nicotine containing e-cigarette and combustible cigarette use also significantly improved overall mood of participants compared to no product use, with no significant differences observed between the nicotine containing products. Nicotine containing e-cigarette and combustible cigarette use significantly reduced smoking urges compared to no product use, though combustible cigarette use elicited the greatest reduction in smoking urges.ConclusionsOverall, the nicotine containing products improved sustained attention and mood while reducing smoking urges, with the studied e-cigarettes having comparable effects to combustible cigarettes across the assessed cognitive parameters and mood measures. These results demonstrate the potential role of e-cigarettes to provide an acceptable alternative for combustible cigarettes among people who would otherwise continue to smoke.Trial registration ISRCTN (identifier: ISRCTN35376793).

Effect of biostimulants on growth and production parameters of green beans (Phaseolus vulgaris L.) cultivated under North African climate

In crop growing, biostimulants are currently used to improve the advance and yield of crops. These biostimulants showed successful effects in various crops against severe stress factors. Therefore, integrative studies are required to define the usage of such products in agriculture. This study investigated the valuable impacts of biostimulants on the growth parameters of green beans (Phaseolus vulgaris) in Morocco known for its harsh climatic conditions. Equally, we studied the effect on the soil characteristics. The growth parameters were the number, length, and weight of leaves and pods, and were measured after, 21, 29, 35, 42, and 49 days of cultivation. The soil parameters were organic matter, macro-elements, and microelements. The obtained results exposed that the number of leaves was enhanced by 52.95 % in plants treated with biostimulants, while the improvement of foliar weight was estimated at 83.45 %. The treatment improved the weight of pods by 50 % after 75 days and by 63.65 % after 90 days. Similarly, the treatment improved the length of pods by 48 % after 75 days and by 78 % after 90 days. The improvement of growth parameters was in a time-dependent manner. These results are the first to clarify the faculty of biostimulants to enhance the growth performance of green beans under North African climatic and soil circumstances. However, more experiments are desired to evaluate the optimum quantities of biostimulants needed to get the maximum yield. Equally, future research is required to assess the influence of biostimulants on the nutritive quality of fruits.

Factors Associated with Exclusive Use of Hygienic Methods during Menstruation among Adolescent Girls (15–19 Years) in Urban India: Evidence from NFHS-5

BackgroundMenstrual hygiene is a critical public health concern for adolescent girls in urban India. However, there is a paucity of research on this subject, particularly on a national scale. To the best of our knowledge, this study diverges from previous research, as the majority of prior investigations in India have centered on rural locales, married individuals, and those aged between 15 and 24 years. Thus, this study aims to fill this gap by investigating the factors associated with the exclusive use of hygienic methods during menstruation among urban adolescent girls (15–19 years) in India. MethodA total of 25136 samples were included in this analysis from the National Family Health Survey 5 (NFHS-5). The Binary logistic regression model has been administered to determine the associated factors of the exclusive use of hygienic methods among adolescent girls. ResultsThe results of the multivariate model revealed significant positive associations between higher education levels and usage of menstrual hygiene management products (AOR: 1.860; 95 % CI: 1.418–2.439), (AOR: 2.110; 95 % CI: 1.553–2.867). Additionally, individuals in higher wealth quintiles were more likely to use MHM products, with the richest quintile showing the highest likelihood (AOR: 5.310; 95 % CI: 4.494–6.275). Attendance at cultural events such as cinema or theater was positively associated with MHM product utilization (AOR: 1.338; 95 % CI: 1.181–1.517).Conversely, Lack of access to sanitation facilities was inversely associated with MHM product utilization (AOR: 0.742; 95 % CI: 0.628–0.877). Muslim girls had lower odds than Hindus (AOR: 0.576; 95 % CI: 0.520–0.637). Substantial regional variations were evident, with the Western (AOR: 0.879; 95 % CI: 0.759–1.019), Eastern (AOR: 0.747; 95 % CI: 0.654–0.854), Central (AOR: 0.349; 95 % CI: 0.313–0.388), and North-eastern regions (AOR: 0.597; 95 % CI: 0.490–0.727) displaying diminished odds of MHM product usage relative to the southern region. General caste had higher odds compared to scheduled caste (AOR: 1.255, 95 % CI: 1.103–1.429), while other backward caste had lower odds (AOR: 0.858, 95 % CI: 0.771–0.955). ConclusionThese findings underscore the importance of addressing inequalities in access to menstrual hygiene products among urban adolescent girls in India. Targeted interventions and educational programs are essential to ensure equitable access and promote overall health and well-being.

Treatment Using Haram Substances According to an Islamic Legal Perspective

In terms of the medical field, it has evolved in tandem with human capabilities and the passage of time. Humans, like all other living things, will inevitably suffer from a variety of illnesses, some minor and others serious. People are encouraged to look for other treatment options in an attempt to overcome this illness, and as a result, it is discovered that the law of treatment—which stipulates which treatments are permitted and which are haram—is connected to the usage of haram products and chemicals. Al-Baqarah verses 168 and 172 provide justification for the use of halal and good food, despite the commandment to abstain from haram items. In deciding how to regard haram items, scholars of the mujtahid school also cite QS Al-Baqarah verse 173. This provider makes use of socialization methods and questions and answers in the studio at...., it is hoped that the studio group will be able to know the law of treatment with haram goods/substances in accordance with the Shari'a specified in Islamic law.

The Role of Indonesian Muslim Millennials in Reducing Food Waste towards Sustainable Development Goals: Empirical Analysis PLS-SEM

Food waste is a critical concern under SDGs 12 due to its global welfare implications. Islam, with its substantial following worldwide, can play a role in addressing this issue, particularly through the involvement of Muslim millennials. This study aims to explore the impact of religiosity, product usage efficiency, and intention to reduce food waste, with da’wah, Instagram, and Muslim eating manners as mediators. Quantitative research was conducted through an online survey of Indonesian millennials using purposive sampling. The research model, consisting of five hypotheses, was analyzed using the PLS-SEM analysis method. Results indicate that individual religiosity significantly influences Instagram proselytizing and eating behavior among Muslim millennials. Instagram proselytizing strongly affects millennial Muslim consumer behavior, particularly in terms of food consumption efficiency. Additionally, Muslim millennials’ eating etiquette impacts food consumption efficiency and environmental awareness. The efficiency of food consumption can shape millennials’ intention to reduce food waste. Implications of this study include promoting millennial involvement in food waste reduction, sustainable agricultural practices, improving literacy on food consumption efficiency, incorporating food waste education in Islamic religious curricula, and fostering collaboration among Muslim millennial organizations in Indonesia’s food waste reduction programs.
