Published: June 2024

This evaluation sought to determine to what extent a suicide prevention service, designed for young people at severe risk of suicide, was successful in reducing suicide risk and distress and improving well-being outcomes. The 3-month service was co-designed at the height of the COVID-19 pandemic in Melbourne, Australia, with young people and carers who had lived experience of youth suicide. The evaluation involved a mixed methods analysis of data collected during the first 20 months of operation, from February 2022 to September 2023. Ninety one young people were admitted to the service during this period, of whom 28 agreed to participate in the evaluation. Primary data were collected by telephone or online, and secondary data for hospital service use were collected for 70 of the young people. Analysis found that there were significant reductions in suicide risk and psychological distress at discharge, associated with significant improvements in quality of life and reductions in the use of hospital services. Qualitative analysis supported these survey results, highlighting the peer and psycho-social support as particularly beneficial aspects of the service. However, the qualitative analysis also indicated that some individuals felt the service was too short and abruptly ended, with insufficient attention paid to the creation and maintenance of support services that could continue after discharge. A small sample size was a limitation of this study, particularly for the three and six month follow-up surveys. Also, the cost-benefit analysis included secondary routine hospital admission data covering only 12 months. Nevertheless, the overall findings are positive, suggesting that services of this nature can have real benefits for young people at serious risk of suicide. It is likely that an extension of the cost-benefit analysis, to allow for benefits beyond a one year period, would have suggested that the benefits outweigh the costs.

Published: June 2024

Background

Clear amniotic fluid aspiration syndrome (CAF-AS) is a very rare event occurring in 0.25% of our term clear amniotic fluids deliveries. The study’s aims were: 1. to characterize the risk factors and outcomes associated with Clear Amniotic Fluid Aspiration Syndrome and 2. to compare the outcomes of Clear Amniotic Fluid Aspiration to Meconium Aspiration.

Methods

This was an observational study over a 22-year period in a single level-3 medical center. Compared were parturient/labor characteristics and neonatal outcomes in cases with suspected Clear Amniotic Fluid Aspiration to cases suspected for Meconium Aspiration.

Results

Out of 79,620 term deliveries there were 66,705 (83.8%) clear amniotic fluids and 12,915 (16.2%) meconium stained amniotic fluid (MSAF). Of neonates born with clear amniotic fluid, 166 (0.25%) were diagnosed with Clear Amniotic Fluid Aspiration Syndrome (CAF-AS), while 202 (15.7%) of those born with MSAF, were diagnosed with aspiration syndrome (MSAF-AS). Both conditions had comparable rates of mild manifestation (67.5% vs 69.2%, p = 0.63). Persistent pulmonary hypertension (PPH) occurred 5 times less in CAF-AS than MSAF-AS (4% vs 20%, OR 0.17, P< 0.0001) Both conditions presented similar rates of surfactant without PPH (11.1% vs 13.4%, p = 0.87). There was 1 postnatal death in CAF-AS vs 10 in MSAF.

Conclusion

CAF-AS were quantitatively quite similar in terms of need of actual active intervention of the neonatologists in the delivery room (166 vs 202, i.e. in terms of numbers of cases and not prevalence) to MSAF-AS.We identified in these cases two major specific causes: hyperkinetic explosive deliveries in multiparas and long-lasting episodes of maternal hypotension due to epidural/spinal anaesthesia during labor. Out of 140 million births per year in the world, it should be of concern that 3 million cases are neglected nowadays. Future studies should evaluate if this CAF-AS should benefit from a more active intervention such as immediate endotracheal suction at birth, this clear fluid being very easy to suction.

Published: June 2024

The study aimed to analyze the tactical sprint actions performed by Spanish professional soccer players, considering their playing positions and the match status at the time of each action. Thirty-two Spanish male professional soccer players from a LaLiga Spanish Second Division (LaLiga SmarthBank) team participated in this study. Actions above 85% of the players’ maximum velocity during 42 official matches were collected by an optical tracking system ChyronHego® and were synchronized using Mediacoach software (LaLiga, Madrid, Spain). Then, actios were analyzed trough an observation instrument designed to assess the type of tactical action performed by players. Central defenders (CD) and wide defenders (WD) were mainly involved in recovery runs. Central midfielders (CM) also frequently performed recovery runs and pressing actions. Wide midfielders (WM) were often engaged in runs in behind/penetrate actions, while forwards (F) had a diverse range of sprint actions, including pressing, runs in behind/penetrate, and breaking into the box. It was observed that F performed fewer chase actions than expected. On the other hand, CD, WD, and CM engaged in a greater number of recovery run actions than expected. CD also performed more close down/interception actions than expected, while CM, WM, and F performed fewer close down/interception actions than expected. When their team was losing, WM performed more recovery run actions than expected. CM made more runs with the ball when their team was winning CD showed a higher frequency of breaks into the box when their team was winning. These findings provide valuable information regarding the tactical aspects of sprinting in soccer, facilitating the design of specific training tasks that not only address the physical demands associated with each playing position but also considering the tactical context in which sprints occur.
Falling into the trap: A study of the cognitive neural mechanisms of immediate rewards impact on consumer attitudes toward forwarding perk advertisements
Authors: Sun Rui , Zuo Jiajia , Chen Xue , Zhu Qiuhua
Published: June 2024

In the context of digital marketing, consumers often express aversion to perk advertisements yet find it challenging to resist the temptation and forward it, resulting in inconsistent attitudes and behaviors. This study, based on the Associative Propositional Evaluation model and the Confirmation Bias theory, utilizes event-related potential experiments to identify the interactive impacts of immediate rewards and information diagnosticity in advertisements on consumer attitude change in specific contexts. The research findings indicate that when rewards were present, information diagnosticity positively influences attitude change and the willingness to forward. However, when rewards were absent, the impact of information diagnosticity on attitude change and the willingness to forward is not significant, and neuroscientific evidence supports these findings. Theoretically, this study extends the research perspective on attitude change in online advertising contexts and broadens the application of the Associative Propositional Evaluation model in the field of consumer attitude change towards advertisements. In practice, this research holds significant guiding value for constraining platform manipulation of consumer cognitive behaviors, guiding the healthy development of platform economics, and promoting digital technology ethics.

Published: June 2024

This body image study tests the viability of transferring a complex psychophysical paradigm from a controlled in-person laboratory task to an online environment. 172 female participants made online judgements about their own body size when viewing images of computer-generated female bodies presented in either in front-view or at 45-degrees in a method of adjustment (MOA) paradigm. The results of these judgements were then compared to the results of two laboratory-based studies (with 96 and 40 female participants respectively) to establish three key findings. Firstly, the results show that the accuracy of online and in-lab estimates of body size are comparable, secondly that the same patterns of visual biases in judgements are shown both in-lab and online, and thirdly online data shows the same view-orientation advantage in accuracy in body size judgements as the laboratory studies. Thus, this study suggests that that online sampling potentially represents a rapid and accurate way of collecting reliable complex behavioural and perceptual data from a more diverse range of participants than is normally sampled in laboratory-based studies. It also offers the potential for designing stratified sampling strategies to construct a truly representative sample of a target population.
A high-speed gear reshaping method for electric vehicles combining the effects of input torque and speed variation
Authors: Liu Weifeng , Wei Cuicui , Wang Bo , Ding Zhicheng , Du Guitao
Published: June 2024

In this study, we introduce an optimization method for high-speed gear trimming in electric vehicles, focusing on variations in input torque and speed. This approach is designed to aid in vibration suppression in electric vehicle gears. We initially use Tooth Contact Analysis (TCA) and Loaded Tooth Contact Analysis (LTCA) to investigate meshing point localization, considering changes in gear tooth surface and deformations due to load. Based on impact mechanics theory, we then derive a formula for the maximum impact force. A 12-degree-of-freedom bending-torsion-axis coupled dynamic model for the helical gear drive in the gearbox’s input stage is developed using the centralized mass method, allowing for an extensive examination of high-speed gear vibration characteristics. Through a genetic algorithm, we optimize the tooth profile and tooth flank parabolic modification coefficients, resulting in optimal vibration-suppressing tooth surfaces. Experimental results under various input torques and speeds demonstrate that the overall vibration amplitude is stable and lower than that of conventional gear shaping methods. Specifically, the root mean square of vibration acceleration along the meshing line under different conditions is 58.02 m/s2 and 20.33 m/s2, respectively. The vibration acceleration in the direction of the meshing line is 20.33 m/s2 and 20.02 m/s2 under varying torques and speeds, with 20.33 m/s2 being the lowest. Furthermore, the average magnitude of the meshing impact force is significantly reduced to 5015.2. This high-speed gear reshaping method not only enhances gear dynamics and reliability by considering changes in input torque and speed but also effectively reduces vibration in electric vehicle gear systems. The study provides valuable insights and methodologies for the design and optimization of electric vehicle gears, focusing on comprehensive improvement in dynamic performance.
Exploring the power of data mining for uncovering traditional medicinal plant knowledge: A case study in Shahrbabak, Iran
Authors: Bibak Hossein , Heydari Farzad , Sadat-Hosseini Mohammad
Published: June 2024

The present study recorded indigenous knowledge of medicinal plants in Shahrbabak, Iran. We described a method using data mining algorithms to predict medicinal plants’ mode of application. Twenty-oneindividuals aged 28 to 81 were interviewed. Firstly, data were collected and analyzed based on quantitative indices such as the informant consensus factor (ICF), the cultural importance index (CI), and the relative frequency of citation (RFC). Secondly, the data was classified by support vector machines, J48 decision trees, neural networks, and logistic regression. So, 141 medicinal plants from 43 botanical families were documented. Lamiaceae, with 18 species, was the dominant family among plants, and plant leaves were most frequently used for medicinal purposes. The decoction was the most commonly used preparation method (56%), and therophytes were the most dominant (48.93%) among plants. Regarding the RFC index, the most important species are Adiantum capillus-veneris L. and Plantago ovata Forssk., while Artemisia auseri Boiss. ranked first based on the CI index. The ICF index demonstrated that metabolic disorders are the most common problems among plants in the Shahrbabak region. Finally, the J48 decision tree algorithm consistently outperforms other methods, achieving 95% accuracy in 10-fold cross-validation and 70–30 data split scenarios. The developed model detects with maximum accuracy how to consume medicinal plants.

Published: June 2024

Objective

This study assessed the impact of nutrient warnings on product selection and ability to identify food products high in nutrients of concern in Colombia.

Methods

In an online experiment (May-June 2023), Colombian adults were randomized to a nutrient warning, guideline daily amounts (GDA), Nutri-Score, or no-label condition (n = 8,004). Participants completed selection tasks between two fruit drinks labeled according to their condition, one high in sugar and one not. Next, participants answered questions about products high in sugar, sodium, and/or saturated fat (“high-in” product). Finally, they selected which label would most discourage them from consuming a high-in product.

Results

Fewer participants (17%) exposed to the nutrient warning indicated they would purchase the high-sugar fruit drink compared to Nutri-Score (27%, Holm-adjusted (adj) p<0.001) and no label conditions (31%, adj p<0.001); there were no differences between the nutrient warning and GDA label (14%, adj p = 0.087). Compared to the nutrient warning, the GDA label was slightly more effective at helping consumers identify which drink was high in sugar (89% versus 92%, adj p<0.001), while the Nutri-Score and no-label conditions were less effective. Compared to all other conditions, nutrient warnings were more effective at helping participants identify that products were high in nutrients of concern, were more effective at decreasing intentions to purchase these high-in products and were perceived as more effective. Nutrient warnings were most often selected as the label that most discouraged consumption.

Conclusions

Nutrient warnings are a promising policy to help consumers identify and discourage consumption of products high in nutrients of concern.

Easing anxiety symptoms through leisure activities during social isolation: Findings from nationally representative samples
Authors: Cheong Queena , Kazanjian Arminee , Puyat Joseph H.
Published: June 2024

Public health interventions implemented during the COVID-19 pandemic may exacerbate anxiety symptoms for many. We conducted this study to better understand the role of leisure activity in promoting mental wellness during times of social isolation and reduced access to recreation facilities and mental health support services. We analyzed nationally representative survey data collected by Statistics Canada as part of the Canadian Perspectives Survey Series (CPSS) during May 4–10 (CPSS 2) and July 20 to 26, 2020 (CPSS 4). Data related to leisure activity and anxiety symptoms as measured by a score of more than 10 on the General Anxiety Disorder scale were examined using descriptive and log-binomial regression analyses. Survey sampling weights were applied in all analyses, and regression results were adjusted for sociodemographic characteristics. Exercise and communication with friends and loved ones were the most frequently reported leisure activity. Prevalence of moderate to severe anxiety symptoms reported by participants was lower in CPSS 4 compared to CPSS 2. Results of adjusted log-binomial regression analyses revealed lower prevalence of moderate to severe anxiety symptoms in those who engaged in exercise and communication, while those who meditated exhibited higher prevalence. In conclusion, leisure activities, such as exercise and communication with loved ones, can promote mental wellness. Future research should clarify the role of meditation for mental wellness promotion during periods of social isolation.

Published: June 2024

Amblyomma americanum, a known vector of multiple tick-borne pathogens, has expanded its geographic distribution across the United States in the past decades. Tick microbiomes may play a role shaping their host’s life history and vectorial capacity. Bacterial communities associated with A. americanum may reflect, or enable, geographic expansion and studying the microbiota will improve understanding of tick-borne disease ecology. We examined the microbiota structure of 189 adult ticks collected in four regions encompassing their historical and current geographic distribution. Both geographic region of origin and sex were significant predictors of alpha diversity. As in other tick models, within-sample diversity was low and uneven given the presence of dominant endosymbionts. Beta diversity analyses revealed that bacterial profiles of ticks of both sexes collected in the West were significantly different from those of the Historic range. Biomarkers were identified for all regions except the historical range. In addition, Bray-Curtis dissimilarities overall increased with distance between sites. Relative quantification of ecological processes showed that, for females and males, respectively, drift and dispersal limitation were the primary drivers of community assembly. Collectively, our findings highlight how microbiota structural variance discriminates the western-expanded populations of A. americanum ticks from the Historical range. Spatial autocorrelation, and particularly the detection of non-selective ecological processes, are indicative of geographic isolation. We also found that prevalence of Ehrlichia chaffeensis, E. ewingii, and Anaplasma phagocytophilum ranged from 3.40–5.11% and did not significantly differ by region. Rickettsia rickettsii was absent from our samples. Our conclusions demonstrate the value of synergistic analysis of biogeographic and microbial ecology data in investigating range expansion in A. americanum and potentially other tick vectors as well.

Published: June 2024

Understanding of soil phosphorus (P) transformation is crucial to minimize its edge-of-field loss associated with ecosystem disservices. A sequential chemical extraction procedure was used to assess the impact (42 years) of organic and chemical fertilizations on soil P partition and distribution under subtropical rice based cropping systems. Experimental treatments were control, N, NP, NK, NS, NZn, NPK, NSZn, NPKSZn, and N+FYM (farmyard manure). Composite soils were collected from 0–5, 20–25 and 40–45 cm depths, extracted, and analyzed for soluble P, NaHCO3-P (inorganic and organic), NaOH-P (inorganic and organic), acid soluble (H2SO4), and residual P fractions. The NPKSZn significantly increased the concentration of soil inorganic P compared to other treatments. When FYM was applied together with N fertilizer, the organic P concentration increased, which was statistically identical to NPKSZn and NPK treatments. While the labile (NaHCO3-Pi, NaOH-Po), residual, and total P concentrations were stratified at 0–5 cm depth, the concentration of NaHCO3-Po, NaOH-Pi, and acidic P fractions increased with soil depth. The soluble, NaHCO3 (Pi and Po), NaOH-Pi and NaOH-Po, acidic, and residual P fractions constituted about 0.4, 6.6, 1.7, 21.3, 37.7, and 8.3%, respectively, of the total P. A higher concentration of the labile P at the surface soil indicated that the impact of chemical fertilization stratified the available P for plant uptake or susceptible to edge-of-field loss. The NPKSZn and N+FYM both had higher NaHCO3-Po and NaOH-Po concentrations within 40–45 cm and 0–25 cm depths, suggesting that N+FYM could promote the transformation of non-labile P into labile P pool, by reducing P fixation by soil and transport them at 20–45 cm depth. It is concluded that long-term fertilization increased the concentration of P pools especially labile P by saturating the soil adsorption sites especially in surface soil.
Capturing ‘small stories’ from the lake: At the MAA/Ground Residency
Authors: Mayo Natasha
Published: June 2024

Drawing has long been established as a conversational tool, as notation passed between individuals or with larger groups to create an evidence trail of ideas. There is a fascinating sociality to the activity, finding parallels with the dynamics of a conversation, as artists enter similar cycles of inspection, re-conception and re-examination, pushing ideas forward, asserting focus and altering original intentions. The MAA/Ground Residency offered the opportunity to examine this sociality on a more nuanced level, by applying approaches commonly used in the practice of oral history, to devise a model of drawing that can sensitize participants to the nature of human interaction and explore the ‘smaller stories’ contained in the details of shared experiences. The following report maps the first stages of this study from initial interaction with the site of the residency at Niemelä house, E. Finland, and onto a series of drawing conversations with its attendees. The results start to show how, as a particular field of the visual arts, the drawing process can be shaped by situated ‘small talk’, reflected in equivalent hesitancies and utterances in emerging and growing ideas, and in turn, how narrative analysis can be used to interpret and explore the sociality of drawing taking place.
Ideologías lingüísticas y su aplicabilidad al estudio sociolingüístico de Galiza
Authors: Amarelo Daniel
Published: June 2024

En primer lugar, este trabajo pretende realizar una revisión bibliográfica del concepto teórico ideologías lingüísticas, surgido en la intersección entre la antropología lingüística y la sociolingüística durante la década de los 90, especialmente en el contexto académico estadounidense. En segundo lugar, plantea algunas posibilidades de aplicación de esta noción teórico-metodológica a la situación sociolingüística de Galiza, una nación sin Estado en el noroeste de la Península Ibérica donde el multilingüismo es objeto de ciertas tensiones sociales y políticas. En ese sentido, se explora la practicidad de esta perspectiva relativamente poco considerada en los estudios previos, analizando ejemplos concretos de discursos y eventos contemporáneos que ayuden a enraizar esta propuesta de forma práctica. Finalmente, se enumeran algunas líneas posibles para la futura investigación, con atención a la integración de las ideologías lingüísticas en las discusiones sociolingüísticas sobre las lenguas minorizadas.
Víctimas y acción política en Justicia y Paz (Ley 975 de 2005)
Authors: Suárez  González María Teresa
Published: June 2024

El presente artículo es producto de las reflexiones suscitadas en el marco de la investigación doctoral Representaciones de Justicia y Paz en la Ley 975 de 2005; ley que dio inicio a lo que en Colombia se conoce como el Proceso de Justicia y Paz, con grupos paramilitares. Se plantea el abordaje de la construcción de la representación de las víctimas en el corpus abordado desde dos ideas. La primera, planteada por Arendt (2011), acerca de la acción y la construcción de lo político y, la segunda, en relación con lo que Fraser (2008), denomina paridad de participación como componente fundamental de la justicia, para así ampliar la comprensión de las representaciones sociales que de las víctimas se hace en este discurso que marcó un proceso de aplicación de la justicia transicional en el siglo XXI en el país.
Discursos sobre la educación de migrantes venezolanos en el Perú: entre la inclusión y la exclusión a estudiar
Authors: Yalta Edgar , Lovón Marco
Published: June 2024

Los migrantes venezolanos en el Perú son víctimas de procesos xenófobos y racistas debido al debate entre su inclusión y exclusión en los sectores del país. En este sentido, el objetivo del presente artículo es analizar la construcción de inclusión y exclusión del sistema educativo peruano hacia el estudiante migrante venezolano a través de la identificación de repertorios interpretativos y estrategias lingüísticas y discursivas. Para ello, metodológicamente, se recurre a los textos periodísticos, discursos escritos, que produjeron los diarios digitales en el Perú para reportar la concepción educativa del migrante venezolano. Los resultados evidencian los siguientes repertorios interpretativos: (1) un sistema educativo peruano inclusivo; (2) un sistema educativo integrador; y (3) un sistema educativo excluyente. Las conclusiones indican que el sistema educativo peruano no es inclusivo con los migrantes venezolanos y que los discursos de inclusión se encuentran mayormente a nivel de propuesta que de acciones o prácticas.
DIGITAL HISTORICAL MEMORY AND CIVIC IDENTITY OF STUDENTS IN THE REGION
Authors: Dadaeva Tatiyana M. , Bogatova Olga A.
Published: June 2024

The article poses the problem of the need to study the influence of digitalization on the formation of the historical memory of young people. Based on data from an online questionnaire (multi-stage combined sample, n = 700), the main vectors of constructing digital historical memory and its influence on the formation of civic identity of college and university students are presented using the example of the Republic of Mordovia. The calculation of the “digital historical memory” index made it possible to determine the directions of digital memory influence on the young people self-identity and on the assessment of the main factors of civic identity. A statistically significant relationship was revealed between the choice of “new media” as a source of historical memory formation and such indicators as age, level of education received. The objectives of the study also included the study of memory nodes (selection of the most significant events from the history of the country), digital practices (activities related to historical Internet resources and portals). The article makes an attempt to sociologically comprehend the production of digital historical memory in modern conditions, which, on the one hand, is hyperconnective, i.e. accessible to a large number of users and hyper-meditated - formed on the basis of various and many sources, and on the other hand, there is a great risk of producing a fake story and its different versions, far from scientific character and objectivity, The authors make the assumption, based on the data obtained, that in the new geopolitical conditions the influence of the “digital memory” index on the formation of Russian identity among young people can be described as positive, although this issue requires further research.
The Universe Never Had the So-Called Gravity
Authors: Le Dieu T
Published: June 2024

This paper challenges conventional gravity theories by revisiting Galileo's discoveries and presenting a counterintuitive perspective. Recent experiments, such as the hammer and feather drop on the moon and vacuum demonstrations on Earth, prompt a reevaluation of our current scientific understanding of gravity. The paper argues that celestial bodies, including Earth, move towards objects, challenging the traditional concept of gravity. Drawing on the equivalence principle and dark matter effects, it contends that objects become stationary when disconnected from their original reference frame. Addressing criticisms, the paper asserts that Earth's perpetual movement ensures uniform gravitational effects globally. Exploring the expanding universe and dark matter's influence, it concludes that objects released in space do not fall but become stationary, prompting a reassessment of established scientific principles. This paradigm shift invites readers to reconsider their understanding of gravity and the universe. The paper is written as a letter to stimulate thought and discussion.

En este artículo se analizan los determinantes de las remesas enviadas por la población de origen latinoamericano residente en la Comunidad Autónoma de Euskadi (CAE) prestando especial atención a las diferencias que se dan entre hombres y mujeres. Partiendo de los datos de la Encuesta de Población Inmigrante Extranjera se han utilizado los procedimientos de regresión logística y regresión lineal para evaluar los factores que influyen en el envío de remesas y en la cantidad de remesas enviadas. Los resultados muestran que las mujeres envían un mayor número de remesas y que, mientras que en el caso de los hombres los factores explicativos de las remesas están alineados con lo propuesto en la literatura sobre determinantes de las remesas; en el caso de las mujeres los envíos se comprenden de manera más adecuada desde una teoría crítica como la de las cadenas globales de cuidados.

La Coordinadora Nacional de Inmigrantes trabaja por la defensa de los derechos humanos de las personas migrantes en Chile. Este artículo analiza los significados construidos por sus integrantes en oposición a los dispositivos necro políticos del Estado, que promueven la idea de “cuerpos ilegítimos en el espacio público”, obligando a la población inmigrante a habitar la zona del no-ser. A partir de un abordaje metodológico cualitativo que articuló entrevistas, cartografías corporales y etnografía digital, junto a un análisis de marcos interpretativos, fue posible ahondar en los significados corporales que se gestan al interior de la Coordinadora. Estos se vinculan con la lucha por el “derecho a existir” y con la demanda de que los cuerpos migrantes puedan ser y estar en el territorio

Mesenchymal stem cells derived from adipose tissue (AD-MSCs) show great potential for repro ductive biotechnology in the livestock sector. However, enzyme-based isolation of MSCs is expensive and time-consuming, so it is still rarely done, especially for applications in the livestock sector in de veloping countries. So, MSCs must be cryopreserved with an efficient cryoprotective agent to be stored and reproduced in various laboratories after isolation. This study was aimed to optimize the cryopreser vation media for adipose-derived MSCs in cattle. This study evaluated the viability, proliferation, and morphology of AD-MSCs. The results of this study indicate that a combination of 10% DMSO, 45% DMEM, and 45% conditioned media significantly improves post-thaw viability, proliferation, and sur vival as compared to other mediums. Furthermore, AD-MSCs cryopreserved in this medium exhibit similar morphology as fresh cells. These findings suggest that the optimized cryopreservation medium can enhance the quality and safety of AD-MSCs for clinical applications in the livestock industry.
The Effect of Calcination Temperature on the Characteristics of CeO2 Synthesized Using the Precipitation Method
Authors: Bahtiar Zidan Alfian , Windarti Tri , Hudiyanti Dwi
Published: June 2024

Cerium oxide (CeO2) was synthesized using the precipitation method at various calcination temperatures ranging from 500 to 700°C. Cerium(III) nitrate hexahydrate (Ce(NO)3.6H2O) was used as the precursor for cerium, while Cetyltrimethylammonium bromide (CTAB) acted as the morphology-directing agent. Characterization results indicated that pure CeO2 was obtained at all calcination temperature variations. Calcination temperature influences crystallinity, crystal size, and CeO2 crystal parameters. The crystallinity and crystal size of CeO2 increased with the rising calcination temperature, reaching values of 81.1–84.5% and 15.58–23.12 nm, respectively, along with larger crystal parameters as the temperature increased (a = 5.406–5.410 Å). Surface morphology showed irregular shapes of CeO2 particles, with decreasing sizes as the calcination temperature increased, ranging from 0.2-5.6 μm at 600°C to 0.12-2.9 μm at 700°C. The Ce/O ratio on the surface increased with the rising calcination temperature, reaching a range of 0.48–0.57. CeO2 obtained from calcination at 600°C exhibited the highest fluorescence emission intensity (λ= 496 nm), indicating the least oxygen vacancies presence. Therefore, for antioxidant and catalyst applications, it is preferable to calcinate CeO2 at 700°C.

Effect of calcium treatment on inclusions in 38CrMoAl high aluminum steel
Authors: Li Yang , Chen Changyong , Zhang Cong , Ma Shuai , Yang Hao , Sun Meng , Cao Haibo , Jiang Zhouhua
Published: June 2024

Three parts of the experiment were mainly carried out in this research: the effect of Ca on inclusions in 38CrMoAl high aluminum steel under atmospheric pressure, the effect of pressure on the solubility of Ca in pure iron under pressurized conditions, and the effect of Ca on inclusions in 38CrMoAl high aluminum steel under pressurized conditions. The results indicated that Ca can significantly transform the inclusions such as Al2O3 and MgO·Al2O3 with high melting points into calcium aluminate inclusions with low melting points. It was found that the pressure condition can significantly improve the solubility of Ca in pure iron and molten steel, which provided reliable data reference and guidance for popularizing Ca treatment of steel under pressure conditions in the future. Finally, the mechanism of inclusion transformation after Ca treatment was put forward. In this study, the theoretical calculation of thermodynamics was closely compared with the experimental data. It was proposed that to modify the inclusions in high aluminum steel into calcium aluminate inclusions with low melting points, it is necessary to accurately control Ca in the target region.
L2 cognitive construal and morphosyntactic acquisition of pseudo-passive constructions
Authors: Zhong Yihang
Published: June 2024

Discussion of the theoretical underpinning of pseudo-passive constructions abounds in generative linguistics and comparative typology. However, the cognitive construal of and morphosyntactic acquisition of (un)grammatical English pseudo-passive constructions by Chinese-speaking L2-English users with different proficiency levels have never been investigated. It is worth examining whether proficiency level modulates constructional acceptability and cognitive construal, which would allow us to infer L2-English users’ morphosyntactic acquisition stages of pseudo-passive constructions. To fill this research gap, the study recruited 120 L2-English speakers with different levels of proficiency and 40 native English speakers to complete a grammaticality judgment test with an acceptance judgment scale from −2 to 2 for 40 ungrammatical pseudo-passive sentences and 40 fillers. Proficiency level significantly correlates with a firmer rejection of ungrammatical pseudo-passive sentences and cognitive construal which is more target-like. Significantly asymmetrical acceptance levels between two types of target ungrammatical constructions are also revealed for low (p = 0.002) and medium proficiency (p = 0.000) groups, demonstrating the type effect on grammaticality judgment and morphosyntactic acquisition.
A systematic review on potential analogy of phytobiomass and soil carbon evaluation methods: Ethiopia insights
Authors: Gelaye Yohannes
Published: June 2024

Forests play a crucial role in mitigating the impacts of climate change by sequestering carbon in their biomass and soil. However, Ethiopia faces the threat of soil carbon emissions due to deforestation and continuous cultivation. This study reviewed the analogies in phytobiomass and soil carbon evaluation methods in Ethiopia. Index-base and year-wise analysis methods were used for the compilation of the study. Developing nations, such as Ethiopia, duly enhance resilient measures to assess forest carbon stocks for effective climate change mitigation, particularly with reference to emissions from deforestation and degradation. Even though more than 90% of Ethiopia’s energy comes from forest biomass, deforestation significantly affects the carbon stored in aboveground biomass, which is the largest reservoir. Estimating forest biomass and carbon emissions entails uncertainties, with error ranges around ±50% for aboveground pools and ±90% for soil carbon pools. Various tier methodologies are employed by experts to estimate forest biomass and carbon stock emissions, with Tier 2 factors serving as default emissions but country-specific factors offering improved accuracy over Tier 1. Tier 3 methodologies require highly specific inventory data on carbon stocks in different pools and common measurements of key carbon stocks. Forest conservation enhances biodiversity, ecosystem resilience, and essential ecosystem services, fostering soil health, regulating water cycles, and supporting diverse plant and animal species. In conclusion, directing efforts towards forest conservation not only helps maintain biodiversity and ecosystem services but also significantly contributes to mitigating climate change by enhancing carbon storage capacities and reducing greenhouse gas emissions.

Organic–inorganic composite antibacterial materials based on silver phthalocyanine-silver (AgPc/Ag) and aminosilane-modified silicate (Ormosil) were synthesized by sol-gel method and in-situ reduction method. The objective of this study was not only the synthesis of Pc-Ormosil and AgPc-Ormosil/Ag composites but also investigated the bacteriostatic ability of the Pc-Ormosil and AgPc-Ormosil/Ag modified fabrics and the relationship between the antibacterial property and the content of composites on non-woven fabric was discussed. Moreover, the laundering durability of the bacteriostatic of the AgPc-Ormosil/Ag-treated fabrics was also examined. The bacteriostatic ability of the Pc-Ormosil and AgPc-Ormosil/Ag modified fabrics against Gram-negative Pseudomonas aeruginosa, Escherichia coli and Gram-positive Staphylococcus aureus, Bacillus subtilis were confirmed by the zone of inhibition and the plate-counting method. The bacteriostatic ability remains even after one laundry cycle.
Preparing new secondary science teachers in the context of sustainable development goals: green and sustainable chemistry
Authors: Bradley John Dolman , Moodie Peter
Published: June 2024

School science teachers have an important role to play in preparing young people for a sustainable future. Yet their teaching is usually constrained by national school curricula, which may be slow to change to address the issues of sustainable development. Initial teacher education should anticipate the required changes in school curricula so that newly qualified teachers are better equipped to implement the changes when they happen. This paper is based upon the situation prevailing in South Africa, a country with some of the best and some of the worst schools in sub-Saharan Africa. It suggests ways that the BEd course for physical science education student teachers can be developed toward education for sustainable development, while accepting the constraints of the national curriculum, which has become the defining structure of the BEd.

This study aims to compare the sensor/Top-of-Atmospheric (TOA) reflectance correction method and surface reflectance correction in the ARVI (Atmospherically Resistant Vegetation Index) vegetation index transformation application. The resulting comparison of the two has a correlation that is not much different, sensor reflectance correction (R = 0.9723) and surface reflectance correction (R = 0.9781) are both able to represent mangrove forest canopy density well. The model accuracy resulting from the surface reflectance correction RMSE 1.408 and MAPE 0.48%, is higher than that of the sensor correction (TOA) which has an RMSE value of 2.184 and MAPE 1.34%. For advanced remote sensing analysis, it is better to perform radiometric correction of surface reflectance because the reflectance value used for analysis is the true reflectance value. The condition of mangroves in Grajagan Bay in Alas Purwo National Park is very well preserved, this is shown by the mangrove canopy density >50% increased by 49.11 Ha in a period of 7 years from 2016 to 2023.

YouTube® is one of the leading platforms for health information. However, the lack of regulation of content and quality raises concerns about accuracy and reliability. CoMICs (Concise Medical Information Cines) are evidence-based short videos created by medical students and junior doctors and reviewed by experts to ensure clinical accuracy. We performed a systematic review to understand the impact of videos on knowledge and awareness about diabetes and PCOS. We then evaluated the quality of YouTube® videos about diabetes and PCOS using various validated quality assessment tools and compared these with CoMICs videos on the same topics. Quality assessment tools like DISCERN, JAMA benchmark criteria, and global quality scale (GQS) score were employed. Some of the authors of this study also co-authored the creation of some of the CoMICs evaluated. Our study revealed that while videos effectively improve understanding of diabetes and PCOS, there are notable differences in quality and reliability of the videos on YouTube®. For diabetes, CoMICs videos had higher DISCERN scores (CoMICs vs YouTube®: 2.4 vs 1.6), superior reliability (P < 0.01), and treatment quality (P < 0.01) and met JAMA criteria for authorship (100% vs 30.6%) and currency (100% vs 53.1%). For PCOS, CoMICs had higher DISCERN scores (2.9 vs 1.9), reliability (P < 0.01), and treatment quality (P < 0.01); met JAMA criteria for authorship (100% vs 34.0%) and currency (100% vs 54.0%); and had higher GQS scores (4.0 vs 3.0). In conclusion, CoMICs outperformed other similar sources on YouTube® in providing reliable evidence-based medical information which may be used for patient education.

Published: June 2024

Although most published cases of lead poisoning come from occupational exposures, some traditional remedies may also contain toxic amounts of lead. Here, we report the case of a 58-year-old female who presented with abdominal pain, generalized tiredness, and decreased food intake, with anemia and elevated levels of lead. The patient was found to be taking herbal capsules for diabetes prior to the presentation. This case highlights the need for increased awareness that some herbal remedies may contain potentially harmful levels of heavy metals, and people who use them are at risk of developing associated toxicities.

Learning points

Individuals who support traditional medicine often incorrectly believe that herbal remedies for diabetes are free from side effects, leading them to favor these treatments over contemporary medications.

Herbal medications are freely available online, even without a prescription.

The accessibility of herbal medicines without prescriptions, coupled with the false belief in their lack of side effects, misleads educated individuals toward quackery treatments. Misinformation spread via social media exacerbates this issue.

Heavy metals are present in toxic levels in the drugs, causing complications.

Lead is the most common heavy metal found in such herbal medicines.

Lead poisoning leads to anemia and other systemic complications which could have been fatal if not found in time.
