Forensic chemical analysis of hydrogen gas explosions in sprinkler pipes
Authors: An Songhie , Park Sungwan
Published: September 2023

Most sprinkler systems in Korea use galvanized steel pipes to extinguish fires. Typically, sprinkler pipes are galvanized with zinc to protect them from corrosion. Although such installations are widely perceived to be safe and hazard-free, the corrosion of zinc within water-filled sprinkler pipes leads to the formation of corrosive products, including hydrogen gas. As hydrogen gas evolves, the pressure inside the closed sprinkler system increases, which in turn increases the risk of fire explosion. In this study, we evaluated several factors that contributed to the formation of hydrogen gas and analyzed the chemical principle of this reaction. Based on the results, we propose certain safety measures that can aid in preventing accidents caused by hydrogen gas. The study findings can form the basis for identifying a safe operating method that can prevent fires and explosions in sprinkler systems.

Authors: Thandavamoorthy Raja , Devarajan Yuvarajan , Kaliappan Nandagopal
Published: September 2023

Bioactive substances such as phenolic compounds, antioxidants, and antibacterial agents are found in natural fibres. In this study, banana fibre was extracted from the trunks of banana plants. Antibacterial activity, FTIR, XRD, and SEM analysis were performed to characterize the banana cellulose fibre, and also raw and alkali-treated banana fibre composite was fabricated with an epoxy matrix. Results of the antibacterial analysis indicate that this banana cellulose fibre strongly impedes bacterial growth with elevated inhibitory zones. The primary peaks observed at 1170 cm−1 and 1426 cm−1 by FTIR analysis correspond to C–O stretching, O–H bending, aliphatic ether, secondary alcohol, and carboxylic acid. The morphological analysis reveals the fibre quality, and the EDX analysis confirms the elements present in the banana cellulose fibre. The XRD results demonstrated a more significant proportion (76.8%) of the amorphous region. This study indicates that banana cellulose fibre could be a promising source of antimicrobial compounds. In addition, the mechanical properties of alkali-treated banana fibre composite were preferable to raw fibre composite by an average of 3% for this banana fibre composite. As a result, this composite can be used to manufacture automobile interior components, as it can reduce the sanitizing periods of interior components during winter months.
Magnetorotational instability in dense electron–positron–ion plasmas
Authors: Usman S. , Mushtaq A.
Published: September 2023

We in this manuscript analyzed the magnetorotational instability (MRI) by using a multi-component quantum fluid model with the effect of spin magnetization in a differentially rotating degenerate electron–positron–ion (e–p–i) quantum plasma. The electrons and positron having the same mass but opposite charge are taken to be degenerate whereas ions are considered as classical owing to their large inertia. The general dispersion relation is derived and a local dispersion relation for MRI is obtained by applying MHD approximations. To obtained MRI and to analyze the results numerically, reduced dispersion relation is derived using the local approximations. The obtained results are applied to the astrophysical situations exist there in the interiors of White Dwarfs and neutron stars. Contribution from spin magnetization and the number densities of electrons and positrons plays a vital role in the dynamics and can alter the instability. The increase in the electron number density, hence spin magnetization enhances the growth rate of the mode and leads the system to instability which results in the core collapse of certain massive stars.

Published: September 2023

Depression is a common psychiatric disorder with high prevalence and mortality rates as well as high risk of serious harm in adolescents that have significant negative impact on families and society. The feeding inhibitor Nesfatin-1 contributes to the regulation of stress and emotion. The purpose of this project was to compare the differences in the levels of Nesfatin-1 between adolescents with depression and healthy adolescents, and verify the association between the levels of Nesfatin-1 and severity of depression in adolescents. Adolescents with depression (n = 61) and healthy adolescents (n = 30) were evaluated. The Hamilton Depression Rating Scale (HAMD-17) was used to classify the adolescents with depression. Thirty-one and thirty-two was assigned to the mild-to-moderate (HAMD-17 ≤ 24) depression group and severe group (HAMD-17 > 24). Plasma Levels of Nesfatin-1 were measured by human ELISA Kit and differences among groups evaluated. Data were analyzed using the statistical software SPSS 23. HAMD-17 score was significantly higher in adolescents with depression than that in the healthy adolescents (P < 0.001). Median plasma Nesfatin-1 levels in adolescents with depression and healthy adolescents differed significantly at 37.3 pg/ml (22.1 pg/ml, 63.6 pg/ml) and 18.1 pg/ml (10.0 pg/ml, 25.7 pg/ml) (p < 0.001). A multivariate logistic regression analysis showed high plasma Nesfatin-1 concentrations were associated with increased risk of depression (OR = 0.914, 95% CI 0.87–0.96, P < 0.001). The receiver operating characteristic curve showed that the area under curve were 0.808 (95% CI 0.722–0.894, P < 0.001). Plasma Nesfatin-1 cut-off point of 32.45 pg/mL showed 59% sensitivity and 100% specificity. Median plasma Nesfatin-1 levels in the severe depression group (n = 30), mild-to-moderate depression group (n = 31), and control group (n = 30) were 53.4 pg/ml (28.2 pg/ml, 149.1 pg/ml), 29.9 pg/ml (14.5 pg/ml, 48.5 pg/ml) and 18.1 pg/ml (10.0 pg/ml, 25.7 pg/ml), and differed significantly among the three groups (P < 0.001). Median plasma level of Nesfatin-1 in males (n = 20) was 38.6 pg/ml (23.5 pg/ml, 70.1 pg/ml), while that in females (n = 41) was 37.3 pg/ml (22.0 pg/ml, 63.6 pg/ml), which was not a significant difference (P > 0.05). Plasma levels of Nesfatin-1 increased with severity of depression in adolescents and may be useful as a biomarker of depression severity. Further studies are needed in future projects.

A 3D-supramolecular nickel integrated Ni-SDZ complex was synthesized using sodium salt of sulfadiazine as the ligand and nickel(II) acetate as the metal salt using a condensation process and slow evaporation approach to growing the single crystal. The metal complex was characterized for its composition, functional groups, surface morphology as well as complex 3D structure, by resorting to various analytical techniques. The interacting surface and stability as well as reactivity of the complex were carried out using the DFT platform. From ADMET parameters, human Intestinal Absorbance data revealed that the compound has the potential to be well absorbed, and also Ni-SDZ complex cannot cross the blood–brain barrier (BBB). Additionally, the complex's DNA binding affinity and in-vivo and in-vitro cytotoxic studies were explored utilizing UV–Vis absorbance titration, viscosity measurements, and S. pombe cells and brine shrimp lethality tests. In visible light radiation, the Ni-SDZ complex displayed exceptional photo-degradation characteristics of approximately 70.19% within 70 min against methylene blue (MB).

Published: September 2023

The mechanisms of acclimating to a nitrogen-fluctuating environment are necessary for the survival of aquatic cyanobacteria in their natural habitats, but our understanding is still far from complete. Here, the synthesis of phycobiliprotein is confirmed to be much earlier than that of photosystem components during recovery from nitrogen chlorosis and an unknown protein Ssr1698 is discovered to be involved in this synthetic process. The unknown protein is further identified as a c-type heme oxygenase (cHO) in tetrapyrrole biosynthetic pathway and catalyzes the opening of heme ring to form biliverdin IXα, which is required for phycobilin production and ensuing phycobiliprotein synthesis. In addition, the cHO-dependent phycobiliprotein is found to be vital for the growth of cyanobacterial cells during chlorosis and regreening through its nitrogen-storage and light-harvesting functions, respectively. Collectively, the cHO expressed preferentially during recovery from nitrogen chlorosis is identified in photosynthetic organisms and the dual function of this enzyme-dependent phycobiliprotein is proposed to be an important mechanism for acclimation of aquatic cyanobacteria to a nitrogen-fluctuating environment.

Published: September 2023

The mid-latitude westerly winds are a major component of the global atmospheric circulation and a dominant factor in mid-latitude climate change. Understanding their behaviour and the controls on their variations under different climate background states is essential for assessing climate system feedback. Here we present a midlatitude North Pacific Ocean aeolian dust record from core NP02 through the last glacial cycle, during which extreme and abrupt climatic oscillations occurred. We find low dust contents during Heinrich stadials 2, 4, 5, and 5a that we attribute using proxy-model comparison to westerly transportation path changes associated with Atlantic meridional overturning circulation (AMOC) reductions, which caused North Atlantic cooling and modified the westerly wave train pattern, particularly over the Tibetan Plateau. The finding that AMOC variations had significant impacts on the westerlies half-way around the world, through ocean-atmosphere interactions, improves understanding of large-scale westerly sensitivity to different climate states.

To clump or not to clump
Authors: Rübke K. , Herrero A. , Puls J.
Published: September 2023

Context. Winds of massive stars have density inhomogeneities (clumping) that may affect the formation of spectral lines in different ways, depending on their formation region. Most of previous and current spectroscopic analyses have been performed in the optical or ultraviolet domain. However, massive stars are often hidden behind dense clouds rendering near-infrared observations necessary. It is thus inevitable to compare the results of such analyses and the effects of clumping in the optical and the near-infrared, where lines share most of the line formation region.

Aims. Our objective is to investigate whether a spectroscopic analysis using either optical or infrared observations results in the same stellar parameters with comparable accuracy, and whether clumping affects them in different ways.

Methods. We analyzed optical and near-infrared observations of a set of massive O stars with spectral types O4-O9.5 and all luminosity classes. We used Fastwind model atmospheres with and without optically thin clumping. We first studied the differences in the stellar parameters derived from the optical and the infrared using unclumped models. Based on a coarse model grid, different clumping stratifications were tested. A subset of four linear clumping laws was selected to study the differences in the stellar parameters derived from clumped and unclumped models, and from the optical and the infrared wavelength regions.

Results. We obtain similar stellar parameters in the optical and the infrared, although with larger uncertainties in the near-infrared, both with and without clumping, albeit with some individual deviating cases. We find that the inclusion of clumping improves the fit to Hα or He II 4686 in the optical for supergiants, as well as that of Brγ in the near-infrared, but it sometimes worsens the fit to He II 2.18 μm. Globally, there are no significant differences when using the clumping laws tested in this work. We also find that the high-lying Br lines in the infrared should be studied in more detail in the future.

Conclusions. The infrared can be used for spectroscopic analyses, giving similar parameters as from the optical, though with larger uncertainties. The best fits to different lines are obtained with different (linear) clumping laws, indicating that the wind structure may be more complex than adopted in the present work. No clumping law results in a better global fit, or improves the consistency between optical and infrared stellar parameters. Our work shows that the optical and infrared lines are not sufficient to break the dichotomy between the mass-loss rate and clumping factor.
Synthesis of NaA-type Zeolite and its sorption properties
Authors: Fayzullaev Normurot , Pardayeva Sohiba
Published: September 2023

In the article, the synthesis of NaA-type zeolite, its processing with alkali and acid, and the sorption capacity of the synthesized sorbent (composition: NaA type zeolite:clay=1:1) concerning Fe3+, Ni2+, Cr3+, Cu2+ were studied. The use of modified clays leads to significant changes in the structural and mechanical properties of the samples. Increasing the pH value of NaA-type zeolite-based moulding materials increases the proportion of plastic deformations by 1.5 times. An increase in the content of NaA-type zeolite in the forming materials sharply increases the percentage of elastic deformations and, as a result, worsens their formation. In turn, changing the type of binder plasticizer, in this case from clay to kaolin, leads to excessive development of plastic deformations, which leads to the appearance of defects during the moulding process. To improve the formation of NaA-type zeolite and clay-based materials, they can be modified with alkali. During the research, it was found that the optimal ratio of zeolite and clay sorbent is 1:1. It was found that replacing the plasticizer with 1M NaOH solution increases the sorption capacity of the recommended sorbent based on NaA type zeolite, and acid treatment of NaA type zeolite causes its crystal structure to be disturbed. It was conducted on a DRON-3M diffractometer. A standard graphite monochromator is attached to the primary X-ray beam. Differential thermal analysis was performed on a Q-1500D (MOM company) derivatography. The heating rate of the samples in the air was 5 and 10 ℃ per minute. Purpose of work- synthesis of NaA-type zeolites and study of their sorption properties.
Estimation of pore sizes in nanoporous materials by argon capillary condensation: the scaling approach
Authors: Valeev Anton , Lomkova Elena , Morozova Elena
Published: September 2023

This work is aimed to develop a model for predicting pore sizes in nanoporous materials using argon as a test fluid over a wide range of temperatures. The model is based on the universal form of the Kelvin equation and accounts for the difference in vapor pressure between the center of the condensation meniscus and in bulk. For the first time, a scaling model was applied to build a two-parameter model for pore size prediction using argon capillary condensation data. A multiparametric approximation was created for convenient direct pore size calculation. The findings of this study have important implications for the design and optimization of mesoporous materials for various applications, including gas storage, catalysis, and separation. The developed model provides a more accurate and reliable method for characterizing nanoporous materials, enabling better prediction of pore sizes at different temperatures.

Published: September 2023

The study aimed to determine the effect of vanillin addition in the organoleptic acceptance of Chlorella-milk beverages. Besides, the protein and total phenolic content were measured in each formula. The sensory acceptance was determined with a 9-scale hedonic score. Just-about-right (JAR) test was done to determine the intensity of each formulation sensory attribute according to panellists’ preferences. The control sample was Chlorella milk which did not contain vanillin or ginger powder. Other samples were the Chlorella-milk beverages which added by 0.05% v/w vanillin powder (F1), 0.1% v/w vanillin powder (F2), 0.05% v/w ginger powder (F3), and 0.1% v/w ginger powder (F4). Sample F2, adding 0.1% v/w vanillin powder, had the best overall acceptance score of 7.10 ± 1.242. The control sample had to be improved by reducing the intensity of the Chlorella aroma. The addition of vanillin reduced respondents’ perception of the Chlorella aroma intensity. The total phenolic content was increased by adding vanillin and ginger powder. There was no significant difference in the protein content. In conclusion, adding vanillin powder to the Chlorella-milk beverages increased organoleptic acceptance. Adding vanillin and ginger powder did not affect protein content negatively but increased the total phenolic content of Chlorella-milk samples.

Published: September 2023

This paper presents a comparative study of the implementation of all-to-all pairs shortest path algorithms, specifically Floyd-Warshall, Johnson’s, and Dijkstra’s. It contributes to a better understanding of their strengths and weaknesses in different types of applications (real-world scenarios). The research demonstrates the use of these algorithms in finding the shortest path between multiple locations using a Google Maps plotter and the Google Maps API. Older research papers have shown a comparison that shows that the Floyd-Warshall algorithm is faster than the other two algorithms in certain scenarios; however, none have brought up the real-world application of such an algorithm. The null hypothesis of this study is that the Floyd-Warshall algorithm is not suitable for use in a real-life application for finding the shortest path compared to Johnson’s algorithm. The results of this study have potential applications in transportation and logistics and will provide useful insights for future work in this field.

Published: September 2023

Technology abuse is rising in an age where communication technology is used daily. This can happen through social platforms, media, and even represented in streaming platforms. Some people can be affected by technology abuse, including sexual objectification victims. This study investigates the impact of disinformation represented in the movie, Photocopier (2021). Therefore, it aims to find the impact of technology-enabled disinformation and how society plays a role in the digital era concerning a sexual objectification case as portrayed in Photocopier (2021) movie. The information is gathered from dialogues and scenes in the movie and then analyzed using cascading theory and sexual objectification theory. The study used a qualitative approach to achieve its goals. The findings suggest that technology has a negative impact on sexual objectification victims due to the rapid transmission of important records, which leads to victim blaming. Furthermore, society purposefully disseminates confidential sexual objectification documents without sympathizing with the victims. Therefore, it can be said that disinformation caused by technological advancement happens and impacts some people negatively. Society must be aware and play a more supporting role, thus resulting in a sustainable society living with technology for more beneficial effect.

Authors: Tabitha Samara Izatia , Sylvina Vivien
Published: September 2023

Twitter allows users to share and discuss their opinions, which creates the urgency to study how the platform shapes its users’ perspectives on diversity in the media. Media is crucial to represent shared beliefs in society. Using the process of the social construction of reality supported by Crystallization assumptions, this study aims to discover how reality is shaped by Twitter discussions about media representation in Ms. Marvel (2022), which touches on gender, racial, and religious representations of underrepresented communities in Hollywood. The scope of research focuses on Indonesia, where gender, race, and religion are considered sensitive topics. This study uses the qualitative methodology and a phenomenology approach and collects data using Twitter Advance Search, semi-structured interviews, digital observation, and literature review. Results show Twitter as a medium for digital conversations about religious representation in the series, along with race (relating to culture and ethnicity) and gender as passive topics. When users understand the context in constructing reality, discussions about different religious practices have a positive sentiment. However, to promote an inclusive and sustainable society that upholds tolerance, the objectivation and internalization stages depend on the quantity and depth of information acquired in the externalization stage.

Authors: Calista Yasmine , Yenni Siswantini
Published: September 2023

Climate change has become one of the most concerning issues in the 21st century. As it becomes a global problem, Indonesia can also feel the significant impact of climate change due to its geographical position. However, the Indonesian public’s attention and awareness regarding climate change are low. One of the ways to spread awareness efficiently is through social media. Social media also has the ability to affect perceptions. Thus, it is important to understand Indonesia, specifically Gen-Z’s characteristics. This study aims to analyze the impact of social media on climate change perceptions using perception indicators and based on geographical position (rural versus urban area). This research focuses on providing insights into how social media platforms can shape understanding and guidance in making environmental campaigns in Jakarta and Bogor. Therefore, this study uses a quantitative descriptive analysis methodology through a questionnaire to collect data. Using Google Forms, the survey was distributed for four days and acquired 400 Gen-Z participants between the ages of 15-23 living in either Jakarta or Bogor. The results of this study found that social media has a small impact on Indonesian Gen-Z climate change perception.

Published: September 2023

The research aims to obtain evidence regarding the effect of financial health and company affecting carbon disclosure in Indonesia with panel data and fixed effect method. The sample used in this research is non-financial sector companies listed on the Indonesia Stock Exchange in 2019-2020. The final sample selected using the purposive sampling method is 102 companies within two years of observation according to predetermined sample criteria: companies in the non-financial sector. This study finds that company size and financial health affect the reduction in carbon emissions that a company generates from its operations. This study also finds that the profitability and size of Indonesian manufacturing companies impact efforts to reduce carbon emissions which are shown in the disclosure of carbon emission reduction activities. However, the level of debt owned by companies does not have a significant impact on efforts to control carbon emissions. This finding implies that large and financially sound companies tend to maintain and reduce the carbon emissions they generate from their operational activities as a form of their responsibility to their stakeholders in a broad view.

African American Vernacular English (AAVE) emerged from the historical context of African American enslavement and represents one of the numerous vernacular languages influenced by English. Today, AAVE is commonly used by African-Americans and non-African-Americans in various media platforms. This research aims to investigate the differences and similarities between AAVE spoken by African American and non-African-American YouTubers in terms of lexicogrammatical features. Additionally, it aims to know the perspectives of Indonesian learners regarding the interpretation and preference of AAVE. The data consist of transcriptions from African American and non-African-American YouTubers speaking in AAVE. The study used a qualitative method, analyzing spoken language in the subjects’ YouTube videos, as well as a quantitative approach by collecting opinions from Indonesian learners through a questionnaire. The results show that African-Americans and non-African-Americans speaking AAVE use similar features, such as simplification of Standard English phrases, consonant cluster simplification, copula absence, slang, and gender-specific terms like “bruh”. Indonesian learners prefer AAVE spoken by African Americans due to its advantage in clarity and acknowledge that non-African Americans may use AAVE depending on contextual factors. This research seeks to foster awareness of AAVE as a cultural expression and address concerns related to cultural appropriation.

Skin burn classification and detection are one of topics worth discussing within the theme of machine vision, as it can either be just a minor medical problem or a life-threatening emergency. By being able to determine and classify the skin burn severity, it can help paramedics give more appropriate treatment for the patient with different severity levels of skin burn. This study aims to approach this topic using a computer vision concept that uses YOLO Algorithms Convolutional Neural Network models that can classify the skin burn degree and determine the burnt area using the bounding boxes feature from these models. This paper was made based on the result of experimentation on the models using a dataset gathered from Kaggle and Roboflow, in which the burnt area on the images was labelled based on the degree of burn (i.e., first-degree, second-degree, or third-degree). This experiment shows the comparison of the performance produced from different models and fine-tuned models which used a similar approach to the YOLO algorithm being implemented on this custom dataset, with YOLOv5l model being the best performing model in the experiment, reaching 73.2%, 79.7%, and 79% before hyperparameter tuning and 75.9%, 83.1%, and 82.9% after hyperparameter tuning for the F1-Score and mAP at 0.5 and 0.5:0.95 respectively. Overall, this study shows how fine-tuning processes can improve some models and how effective these models doing this task, and whether by using this approach, the selected models can be implemented in real life situations.
