Black pepper (Piper nigrum L.), is a woody perennial climbing plant belonging to family Piperaceae and the most consumed spice in the world. Although the support tree Gliricidia (Gliricidia sepium) is pruned 3 to 4 times per year, pepper vines are not annually pruned in Sri Lanka. The characteristic cylindrical compact canopy of pepper is inefficient in intercepting solar radiation compared to most other vine crops. Therefore, this study was conducted to investigate the effect of different canopy pruning practices on the Photosynthetically Active Radiation (PAR) interception efficiency of the plant canopy and its effect on the yield. Four treatments on pruning practices were compared to each other. Treatments were, T1 – Control (no pruning); T2 - maintaining cone-shaped canopy by pruning only the plagiotropic branches; T3 - partial pruning of lateral branches of only the upper half (layer 1 and layer 2) of the canopy; and T4 - removal of 25% of lateral branches allowing uniform distribution of sunlight all over the canopy (loose canopy). The results revealed that T2 and T4 pruning methods significantly improved the yield (P<0.05) compared to T1 and T3. Hence, both modifying the cone-shaped canopy and maintaining a loose canopy all over the plant are better pruning practices to maximize yield through efficient PAR absorption. Therefore, adopting either of these pruning methods can be recommended as better practices for farmers to maximize their crop yield.

This study aimed to analyze the acute impact of exercise on serum irisin levels in 22 young (YA, 24.6 ± 3.5 yrs) and in 12 middle-aged male adults (MA, 54.6 ± 5.7 yrs) 15 min and 24 h after an incremental cycling exercise test to exhaustion. ELISA assay was used for serum irisin detection. Circulating irisin increased significantly from baseline (9.0 ± 2.0 ng/ml) to 15 min post-exercise (10.2 ± 2.0 ng/ml, P < 0.001), but the greatest increment was detected after 24 h (13.5 ± 2.5 ng/ml, P < 0.001) reaching more than 50% of the basal release. Levels were significantly higher in YA (9.7 ± 1.7 to 11.1 ± 1.8 to 14.5 ± 2.2 ng/ml) than MA (7.6 ± 1.6 to 8.7 ± 1.5 to 11.8± 2.2 ng/ml) for all measured time-points (P < 0.05). Nevertheless, MA showed a comparable increase in serum irisin levels when compared to YA. These findings highlight the importance of acute physical exercise as a countermeasure against age-related deterioration of skeletal muscle mass and function in both YA and MA.
The impact of the Le-Diabet application on self-efficacy and blood glucose levels in diabetes mellitus patients
Authors: Erlina Lina , Hastuti Widi
Published: July 2024

Le-Diabet is an Android mobile application developed for diabetes management whose effectiveness has remained unknown. This research aimed to investigate its impact on self-efficacy and blood glucose levels in patients with diabetes. Employing a quasi-experimental approach, the study utilized a pretest and posttest control group design. The sample included 28 respondents in the control group and 34 in the intervention group, selected through purposive sampling based on criteria such as diagnosed diabetes, smartphone usage, and 6 weeks of using the Le-Diabet application. Self-efficacy was measured using the Diabetes Management Self-Efficacy Scale, while blood glucose levels were monitored with a glucometer. Data analysis involved paired and unpaired t-tests. The results revealed a significant increase in self-efficacy scores by 3.1 points [p=0.000, 95% confidence interval (CI) = -6.006 to -1.876] in the intervention group, whereas the control group experienced a decrease of 1.9 points. Both groups exhibited an increase in blood glucose levels, with a significant rise of 35.6 mg/dL (p=0.035, 95% CI = -68.578 to -2.636) in the control group and a non-significant increase of 3.59 mg/dL (p=0.076, 95% CI = -22.759 to 15.582) in the intervention group. The research concludes that the use of the Le-Diabet application enhances self-efficacy and maintains blood glucose level stability; however, it has not shown an impact on metabolic syndrome indicators in diabetic patients. Further research is needed, utilizing a larger and more diverse sample from various age groups and extending the duration of the study to evaluate the long-term impact of the applied intervention.
The addition of ascorbic acid improves the microbiological quality and shelf life of Atlantic mackerel (Scomber scombrus) fillets stored in ice

Published: July 2024

Ascorbic acid is one of the most promising additives for improving fish shelf life, but studies on its antimicrobial activity during product storage are limited. In this experiment, we assessed the effect of ascorbic acid on the preservability of Atlantic mackerel (Scomber scombrus) fillets during storage in ice. Fillets were treated to reach an ascorbic acid concentration of 0.30 mg/g (T1) and 0.15 mg/g (T2). Samples were stored in ice at 0°C and analyzed at 0, 2, 7, 9, and 14 days for total viable count, specific spoilage organisms (SSOs), Pseudomonas spp., potentially histamine-producing bacteria (HPB), and Enterobacteriaceae. Growth curves were constructed using the DMfit tool of Combase, and the shelf life was estimated in relation to microbiological limits reported in the literature. Sensory evaluation was performed using a quality index method scheme. At 7 and 9 days of storage, treated samples exhibited bacterial counts from 0.5 to 1.7 Log CFU/g lower than controls, with a logarithmic reduction proportional to the additive concentration. The antimicrobial action appeared to diminish after 14 days. A consistent effect was observed for potentially HPB, with counts of 1.7 Log CFU/g lower in T1 samples compared to controls at 9 days. The moderate effect on SSOs limited the estimated shelf life, as the critical limit was reached after 7 days and 8.4 days (T1 and T2). Ascorbic acid positively impacted the microbiological characteristics of mackerel fillets. Further investigation into the decay dynamics of the additive in fish products during storage is advisable.

Published: July 2024

Исследуются распространение автоволнового фронта в среде с разрывными характеристиками и условия его стабилизации к стационарному решению с большим градиентом на границе раздела сред в одномерном случае. Основным методом исследования является асимптотический метод дифференциальных неравенств, который предполагает построение асимптотического приближения решения. Разработан алгоритм построения такого приближения для решения вида движущегося фронта в среде с разрывными характеристиками. Применение этого алгоритма в настоящей задаче требует детального рассмотрения поведения решения в окрестности двух особых точек: точки локализации фронта и точки разрыва сред. Это приводит к тому, что для определения скорости движения фронта получается система уравнений, это отличает настоящую работу от ранее опубликованных. Разработанный алгоритм может быть использован для описания распространения автоволн в слоистых средах. Также возможно распространение результатов на многомерный случай.

The current study was done at Department of pediatrics, Sir Padampat Institute of Neonatology and Pediatric Health, Sawai Man Singh Medical College, Jaipur. It was an observational study and institution ethics committee approved the study. Patients visiting the outpatient department or admitting in wards with clinical presentation suggestive of WD were enrolled in the study after obtaining a valid informed written consent. Patients subjected to detailed clinical history and physical examination. All patients subjected to routine blood count, biochemistry including liver function tests and specific laboratory investigations. They underwent ophthalmological examination. Ultrasonography abdomen and liver biopsy performed in enrolled patients. Magnetic resonance imaging brain carried out in patients with neurological WD. Ferenci score was calculated for each of the patients. Total 50 patients were included in the study. Mean age at the time of diagnosis was 9.4 years with delay of 11 months after onset of symptoms. Male is to female ratio was 2/1. Hepatic manifestation were seen in 76% patients and 24% patients presented with neurological disease. Kayser-Fleischer ring was seen in 44% patients with hepatic disease and 83% patients with neurological disease. Twenty-four hour urinary copper was more than 2 time of upper limit of normal in all patients. Fifty-four percent patients showed improvement with chelation therapy and 9 patients died during the study period. WD in children has varied clinical manifestation and early diagnosis is necessary for good prognosis. It requires wide range of tests as genetic testing is not easily available. Acute liver failure has high mortality. Early chelation therapy reverses the clinical and biochemical abnormalities.
“Slings and Arrows of Outrageous Fortune”: Post-Pandemic Anglophone Theatre and Drama
Authors: Čirić-Fazlija Ifeta
Published: July 2024

Since the days of their conception and for most of their history, theatre institutions and the dramatic genre have indelibly reflected their immediate socio-historic contexts, including epidemics. Although forced to close for a full year during the 1918 outbreak of Spanish flu, however, modern Anglophone theatres and authors deliberately avoided exploiting the pandemic in their works. Conversely, the COVID-19 pandemic directly affected the birthing of new genres and individual plays that included it in their settings and contents, and also motivated discussions on the future of dramatic literature and theatre establishments, particularly with regard to hybrid drama. Building on its author’s previous research, this paper examines British and American dramatic literature and theatre establishments one year after the end of the pandemic, to detect whether Anglophone drama has embraced the new genres, and whether its authors have continued to reflect the pandemic in their works.

Women, Biblical Texts and COVID-19 in Zimbabwe: Navigating the Mental Health Terrain
Authors: Manyonganise Molly
Published: July 2024

From its onset in Zimbabwe, COVID-19 disrupted the mental health of many Zimbabweans. Its quick transmission and viciousness caused fear and panic as people tried to ensure their safety from infection. When lockdown was first declared as the death toll slowly climbed up, it became clear that a number of people would suffer from mental health problems mainly because of isolation, failure to take care of the sick loved ones as well as stigmatization of those who got infected and recovered. In most cases, name calling resulted from ignorance of how to treat those who had recovered from the disease. While recovery was celebrated, the recovered patients were labelled as ‘vaya vakamborwara neCOVID’ (those ones who once suffered from COVID) or ‘pamba peveCOVID-19’ (the home of the COVID-19 sufferers, sic). As infection cases soared and hope seemed to be lost, many people turned to religion. The genderedness of the pandemic became clear as women suffered the most, both as carergivers for the sick as well as from Gender-based Violence (GBV). In such cases, the deployment of biblical texts took centre-stage in most Zimbabwean societies and beyond as women tried to make meaning of their situation. The purpose of this article, therefore, is to investigate how biblical texts were deployed by women for the sake of taking care of their mental health in a threatening environment. The intention is to establish the many ways that religion becomes a useful resource in pandemic contexts particularly for the mental wellbeing of women in Zimbabwe. This is largely a qualitative paper which utilizes in-depth interviews of women in Harare’s Central Business District (CBD). The African Womanist Approach informs the study.
Double pandemic for Sub-Saharan African women during COVID-19: A Critical Patriarchal Exposé with Intervention Strategies
Authors: Jeawon Rosheen
Published: July 2024

The Covid-19 pandemic presented a lot of macro and micro challenges throughout the entire world. While some of these impacts were immediately felt, others have long term consequences. Some of the major impacts were the macroeconomic challenge which left many governments, organisations and individuals in a state of disarray - causing a lot of physical and mental health issues among both men and women. However, research suggests that women were disproportionately affected by mental health issues. This is because women especially in Sub-Saharan Africa are considered to be ‘vulnerable’ to several of the major challenges facing the continent and the burdens they carry make them susceptible to mental health problems. Against this background, this study explores three key areas: the relationship between patriarchy and gender-based violence during COVID-19 in Africa, how the pandemic exacerbated existing gender inequalities, and the impact of COVID-19 on women's mental health. This study is a literature review that draws on academic journals, books, reports, media sources and electronic databases. The study concludes that the COVID-19 pandemic disproportionately impacted African women, leading to a rise in gender-based violence, a widening of existing gender inequalities, and a negative impact on women’s mental health. The study recommends strengthening existing traditional social support structures, such as families and women's groups, to better equip them to assist women during crises.

Resolviendo racionalmente los desacuerdos profundos: hacia una noción de racionalidad concreta
Authors: Roca Rafael
Published: July 2024

Un debate actual dentro de la epistemología, sobre todo en su versión anglosajona, es el de los desacuerdos profundos. Aunque la noción no es del todo unívoca, los desacuerdos profundos se entienden generalmente como desacuerdos sobre las proposiciones que enmarcan nuestra racionalidad. Una cuestión recurrente es si tales desacuerdos pueden resolverse racionalmente. Este artículo hará una presentación general del estado de la cuestión para proponer que este segundo problema está mal planteado, ya que se aborda desde una noción de racionalidad abstracta que no se ajusta a nuestro uso habitual de la razón.
Reinterpretasi Teologis Steriotipe Perempuan sebagai Paboru dalam Struktur Tolu Sahundulan Lima Saodaran
Authors: Saragih Erman Sepniagus
Published: July 2024

Artikel ini menyoal tentang stereotipe perempuan dalam sistem kekerabatan Tolu Sahundulan Lima Saodoran (TSLS) di Simalungun yang terkonspirasi konstruksi teologi patriarki dan saling berkelindan membentuk kesadaran kolektif. Reinterpretasi dilakukan sebagai sebuah upaya menstimulasi kesadaran bahwa perempuan tidak hanya ditempatkan pada fungsi makna definitif atas dasar tuntutan adat, tetapi mereka sudah saatnya memiliki kesadaran kemajuan dalam bentuk kehadiran dalam makna baru di ruang-ruang publik. Metode yang digunakan yaitu penelitian kualitatif deskriptif pendekatan wawancara dan studi literatur sekunder dengan prinsip dialog dan kritik teologi feminis. Simpulannya adalah bahwa citra inferioritas perempuan dan stereotipe perempuan dalam struktur adat simalungun penting dibaca dan dimaknai ulang yang dipelopori oleh GKPS, cendikiawan perempuan Simalungun, dan para teolog-teolog perempuan. Makna paboru dalam TSLS memiliki kesamaan dengan berbagai cara Allah menyatakan kasih keibuan-Nya kepada bangsa Israel di padang gurun, kepada 5.000 orang yang kelaparan, dan cara Yesus memberi kehidupan melalui pelayanan meja dengan menyediakan roti dan anggur. Dengan demikian, kewajiban hukum adat bagi klan perempuan sangat penting dimaknai secara teologis sebab suksesnya pelaksanaan adat tidak akan tercapai tanpa paboru sebagaimana manifestasi eksistensi Allah yang mengibu merawat umat-Nya dan memberi kehidupan.

Artikel ini menelaah sejarah perkembangan kekristenan di Tegal sebagai tempat dimana pertama kali Nederlandsche Gereformeerde Zendingsvereeniging (NGZV) berkarya di Jawa Tengah pada tahun 1862. Aart Vermeer yang diutus oleh NGZV membuka wilayah baru di utara Tegal dan membangun komunitas Kristen disana. Pertumbuhannya tidak cukup signifikan hingga pada 1904, Neukirchener Mission atau De Bond van Zendeling van de Salatiga Zending op Java (Salatiga Zending), menggantikan NGZV melayani umat Kristen Tegal hingga kurang lebih tahun 1942. Data dalam penelitian sejarah ini berasal dari arsip, dokumen, koran serta catatan yang berkaitan dengan tema penelitian. berdasarkan penelusuran historis tersebut ditemukan fakta bahwa sejarah dan pertumbuhan kekristenan pribumi (Jawa) di Tegal tidak bisa dilepaskan dari sebuah tempat bernama Muaratua yang menjadi lanskap mula-mula. Pelayanan beralih dari NGZV ke Salatiga Zending, yang mempengaruhi pola pelayanan kepada kelompok Kristen di Muaratua dan Tegal pada umumnya.
AI GENERATIVE CHATBOT IN THE MEDIA: JOURNALISTIC COVERAGE OF CHATGPT IN BOSNIA AND HERZEGOVINA
Authors: Mahmutović Mirza ,   Faculty of Humanities and Social Sciences, University of Tuzla, Bosnia and Herzegovina
Published: July 2024

In diffusion research, journalistic coverage is acknowledged as a significant factor in spreading awareness and fostering knowledge about innovation, potentially accelerating or impeding the adoption process. With regards to AI-related innovations, this dynamic has largely been studied within the context of Western developed countries. There is far less understanding of how this process unfolds in the news ecosystem of post-communist countries, particularly those with lower democratic standards and weaker economic development, such as Bosnia and Herzegovina. With the intention of gaining preliminary insights, this study investigated how the journalistic organizations in Bosnia and Herzegovina covered the emergence and societal adoption of ChatGPT, a novel form of generative AI, during the initial six-month period following its widespread availability. The content analysis of relevant news messages (N=542) published by 40 legacy and digital- only news outlets was used to explore the key characteristics of journalistic coverage, the attention given to the issue over time and the media depictions of this innovative AI technology. Results indicate that a small group of news outlets, predominantly legacy news organizations, provided significantly more content on ChatGPT than others, particularly public broadcasting services. Findings highlight a tendency among news outlets to focus on either the risks or benefits of ChatGPT and similar AI-based products and amplify sources associated with the business sector and high-tech industry, overrepresented by male voices.
IN THE WAVES OF THE COMMUNICATION FLOOD WITHOUT THE “OLD TESTAMENT ARK” OF CULTURE
Authors: Obradović Neven ,   University of Niš, Faculty of Philosophy
Published: July 2024

The collection of essays “Sharing Opinions” published in 1997 by Miroljub Radojković, professor at the Faculty of Political Sciences from Belgrade, also contains an essay from 1981 titled “The Communication Flood and the ‘Old Testament Ark’ of Culture”. The author of the essay offers a critical analysis of the changes brought about by the era’s new communications technologies and how they impact both society and an individual. Forty-three years later, the overview of how communication technology would grow in the future is especially impressive when viewed from today’s perspective. In the early 1980s, the technical concepts and predictions that the author wrote about - such as working from home, remote learning, and the smart watch - seemed like science fiction. The “look into the future” section of the aforementioned essay, in which communication technologies play a significant role in shaping culture and social connections, is, however, its most significant component. Radojković uses the “power of sociological imagination” to offer partially positive, but mostly negative responses to questions about the future of morality in that new society, as well as the place of art or religion.The author of this paper wants to examine the futuristic theses that were developed more than 40 years ago by looking at them through the lens of contemporary communication technology and its effects on society. The main research inquiry is derived from Miroljub Radojković’s thesis regarding the communication flood (or “floods of generality”) that will endanger the fundamental cultural values based on interpersonal interaction, human engagement with nature, and the symbolic environment, and it is as follows - why, in spite of the warnings, did man encounter the communication flood without the “Old Testament ark” of culture?
Los efectos del incumplimiento de la reparación integral en las víctimas de delitos penales: Un análisis contextualizado desde la perspectiva del derecho penal en Ecuador
Authors: González Zumba Viviana Noemí , Monsalve Robalino Bernardo Xavier
Published: July 2024

La reparación integral a las víctimas de delitos penales es un aspecto crucial para su proceso de recuperación y para garantizar una justicia efectiva. Sin embargo, en Ecuador, se enfrentan desafíos significativos en la implementación de estas medidas, lo que puede tener consecuencias negativas en el bienestar emocional y la percepción de justicia de las víctimas. El objetivo principal de este estudio es analizar los efectos del incumplimiento de la reparación integral en las víctimas de delitos penales en Ecuador. La investigación se llevó a cabo respetando principios éticos fundamentales, con una muestra de 50 participantes divididos en víctimas y profesionales del sistema de justicia penal. Se utilizaron técnicas cualitativas y cuantitativas para recopilar y analizar los datos, incluyendo entrevistas y cuestionarios estructurados. Se identificó que el incumplimiento de la reparación integral se manifestaba principalmente en la falta de pago de indemnizaciones económicas y en la deficiencia en la implementación de medidas de rehabilitación. Estos incumplimientos tuvieron efectos significativos en la salud mental y el bienestar emocional de las víctimas, exacerbando su vulnerabilidad y dificultando su proceso de recuperación. Los resultados de la investigación confirman la existencia de un problema significativo de incumplimiento de la reparación integral en Ecuador, afectando a un amplio espectro de víctimas de delitos penales. Es fundamental fortalecer la aplicación de las leyes y normativas existentes, promover una cultura de respeto a los derechos de las víctimas y garantizar una reparación integral efectiva para todas las víctimas.

Zinc deficiency poses a serious threat to numerous crops and global human populations. Recently, soil biochar amendment has being promoted as a sustainable farming method. However, its consequence on the bioavailability of Zn in cereal crop has not been fully addressed. In the present study, 0.01% Zn-SO4 (w/w) was loaded in fruit waste, farmyard manure and coconut shell pyrolysis at 400 ℃, for 2 h to make fruit waste Zn-modified biochar (FWZn-MBC), farmyard manure Zn-modified biochar (FYZn-MBC) and coconut shell Zn-modified biochar (CSZn-MBC). Except control treatment, all the modified biochars were applied at 1, 2 and 4% doses on zinc availability, speciation, bajra growth and chemical properties in Zn-deficient soil. The obtained results showed that Zn mobility in soil was 70.04% with application of FYZn-MBC 4% as compared with other treatments. The maximum uptake of Zn in shoot and root by bajra plant was observed by 74.02% and 53% with addition of FYZn-MBC 4% as compared with control soil, due to an increase of soil organic matter. The chlorophyll SPAD values in the bajra aerial surface was increased from 30.23 to 39.24 with application FYZn-MBC 4% than control. The exchangeable fraction of Zn was increased from 7.34 to 14.71% with application of FYZn-MBC 4%. The correlation matrix results indicated that CaCO3 was positively correlated with soil pH. Soil organic matter was highly significant correlated with chlorophyll. Overall, future studies must be carried out to examine the long-term impact of FYZn-MBC 4% on Zn phytoavailbility in Zn-deficient soil.

Authors: Sora Shamil Alo , Guji Merga Jibat
Published: July 2024

The fruit with the most commercial significance in the Caricaceae family is the papaya (Carica papaya L.). The fruits are very valuable in terms of nutrition, economy, and medicine. One of the things restricting its production and productivity in Ethiopia is the lack of improved cultivars. In order to determine the optimum high yielding, pest and disease tolerant, variety/ies for the target area, this study was carried out to evaluate the performance of improved papaya varieties. Three newly released papaya varieties were brought to Teppi agricultural research center from Melkassa agricultural research center for evaluation over the cropping seasons of 2019/20 to 2020/21. The experiment was laid out in randomized complete block design and replicated three times. The mean yield was ranged from 34.24 to 90.08 t/ha for Braz-HS1 and Meki-HL1 varieties respectively. The findings of the study revealed that, based on the recorded parameters Meki-HL1 variety performed better followed by Koka-HM1 variety and these two varieties will be recommended for the surrounding farmers for wider production. Further study should be carried out with improved varieties to improve papaya production and nutritional security as well, especially in southwestern Ethiopia.

Published: July 2024

Cat's whiskers plant is an ornamental plant used as a medicinal plant. The part of the cat's whiskers plant used is leaves. Accessions and harvest intervals are essential for increasing optimal yields to plant biomass growth and results. This study aims to determine the effect of differences in accession, intervals, and interactions between accession differences and intervals on the growth and production of a cat's whiskers biomass. The design used in this study is a complete group design of being randomized with two treatment factors. The first factor has two treatment levels: white flowering accessions (A1) and purple flowering accessions (A2). The second factor is a harvest interval with four treatment levels, namely a 1-week harvest interval (P1), two weeks (P2), three weeks (P3), and six weeks (P4). The results showed that accession treatment significantly affected the number of books, number of branches, flowering ages, leaf fresh weight, leaf dry weight, and leaf simplicia yields. Harvest interval treatment significantly affects the height of the shoots, number of shoots, number of branches, number of leaves, flowering ages, leaf fresh weight, stem fresh weight, flower fresh weight, leaf dry weight, stem dry weight, flower dry weight, and leaf simplicia yield. Accession interactions with harvest intervals significantly affect the height of the shoots, number of shoots, number of branches, number of leaves, flower fresh weight, stem dry weight, and leaf simplicia yields.

Durio zibethinus Murray or durian is an exotic tropical fruit native to Southeast Asia. Durian seeds (DS) which mainly composed of mucilage and fibers are generally discarded as agricultural waste post-consumption, yet have promising characteristics as innovative food ingredients with high economic value. Enzymatic-assisted extraction of protein-polysaccharide gum (E-PG) from DS improved the yield efficiency by 4.36-fold with 3.0% celullase, and moisture content in the range of 4-6% (dry weight). Proximate composition for the total carbohydrate, dietary fiber, sugar and crude protein were found at 74.4, 24.0, 4.0 and 10.1 g/100 g of sample. E-PG recorded higher water-holding and oil-holding capacities, and solubility percentage as compared with non-enzymatically extract of protein-polysaccharide gum (N-PG) and DS flour. Physicochemical characteristics revealed E-PG was 2.52-fold lower than xanthan gum (XG AD). Validation on E-PG2.52-fold revealed that the viscosity matched the quality of XG AD. Characterization with HPLC-RID, FT-IR and 1N-NMR highlighted typical distribution of polysaccharides and protein, thus confirming the presence of protein/polysaccharides-based components in E-PG and N-PG. Antioxidant evaluation revealed that E-PG and E-PGslurry scavenged ABTS•+-radicals at an IC50 of 5.759±0.719 and 6.083±0.131 mg/mL, and ORAC values of 57867±2873 and 70191±6291 µM TE/g, respectively, whereas ORAC activity for XG AD was not detected. The recovery of water-soluble protein-polysaccharides gum from non-traditional source like DS via deployment of enzymatic-assisted extraction protocol has improved the extraction yield and enhanced antioxidative capacity of the gum, greater than commercial gums. Findings may significantly influence the food and/or nutraceutical industries on the utilization of value-added and innovative food ingredients in their product formulation.

Boba is a drink originating from Taiwan that has become popular in the Indonesian beverage industry in recent years. This drink consists of a mixture of tea with fruit or milk flavors, with the addition of tapioca-based black chewy textured balls called bubble pearls/boba. Bubble pearls made from tapioca are known to have low nutrition and fiber, so it is necessary to improve their functional characteristics by utilizing local commodities, one of which is porang. Porang (Amorphophallus oncophyllus Prain) as one of the local commodities has the potential to improve the characteristics of bubble pearls. Glucomannan flour from porang tubers has high glucomannan content, quite high fiber content, and can form a gel. This study aims to determine the characteristics of bubble pearl products with the addition of glucomannan flour and to determine the optimum percentage of glucomannan flour and tapioca. The formulation of bubble pearls was carried out using the Simplex Lattice Design method and their physical, chemical, and hedonic characteristics were analyzed. The optimization parameters included water absorption capacity, gumminess level, and dietary fiber content. The optimum formula produced by the Simplex Lattice Design method is in formula 2, bubble pearls with the addition of 25% glucomannan flour which has the highest desirability value of 0.862. Formula 2 consists of a water absorption capacity of 37.08%, a gumminess level of 45.72 gf, and a dietary fiber content of 5.65%. The hedonic values are 5.73 for color (slightly like), 5.7 for aroma (slightly like), 4.8 for hardness (neutral), 4.73 for chewiness (neutral), 5.23 for taste (slightly like), and 5.4 overall (slightly like). Additionally, the water content is 59.97% and the ash content is 1.41%.

A study was conducted to evaluate the performance of compound gates in flow energy dissipation using a two-tiered structure (15 and 30 cm high). Four heights of the lower opening of the structure (0, 1, 2, 3 cm) were used, and seven values of flow depth over the edge of the structure (2, 3, 4, 5, 6, 7, 8 cm) were used for each case. The study concluded that the efficiency of compound gates in dissipating flow energy decreases with increasing flow depth over the edge of the structure. However, this performance increases in hydraulic structures with high elevations, especially when the height of the opening under those gates is increased, provided that the flow depth over the edge of these structures is constant. Compound gates are considered effective energy dissipaters for low-elevation structures if the opening under the gate is small.

A combined semi-discretized spectral matrix collocation algorithm based on (new) family of Krawtchouk polynomials is proposed to solve the time-dependent nonlinear auto-catalytic glycolysis reaction-diffusion system arising in mathematical chemistry. The first stage of the numerical algorithm is devoted to the Taylor series time advancement procedure yielding to a (linear and steady) system of ODEs. In the second stage and in each time frame, a matrix collocation technique based on the Krawtchouk polynomials is utilized to the resulting system of ODEs in an iterative manner. The results of the performed numerical experiments with Neumann boundary conditions are given to show the utility and applicability of the combined Taylor-Krawtchouk spectral collocation algorithm. The positive property of the glycolysis chemical model is sustained by the proposed algorithm and verified through comparisons with existing numerical methods in the literature. The combined technique is simple and flexible enough to easily produce the approximate solutions of diverse physical and applied models in engineering and science.

Herein, we developed the first report on the chemical retrial queue and hybrid vacation process for the significant Ullmann coupling for enhanced high-throughput reaction discovery. The problem of controlling the waiting time for chemical retrials is addressed here. We incorporated the supplementary variables method (SVT) and generated the steady-state probability generating function (PGF) for system size and orbit size. Important cases are outlined, and a few key metrics are utilized to evaluate system performance. Additionally, the impact of changing certain system parameters has also been analyzed via numerical examples. One particularly interesting aspect of this research is the comparison of neuro-fuzzy technique results with validation results utilizing the "adaptive neuro-fuzzy inference system" (ANFIS).

In this article we investigate the question which local symmetry preserving operations can not only preserve, but also increase the symmetry of a polyhedral map, e.g. modelling spherical or toroidal fullerenes. Often operations that can increase symmetry, can nevertheless not do so for polyhedral maps of every genus. So for maps that can increase symmetry, we also investigate for which genera they can do so. We give complete answers for operations with inflation factor at most 6 (that is: that increase the number of edges by a factor of at most 6) and for the chemically relevant Goldberg-Coxeter operations and the leapfrog operation.

The notion of hyperstructures first introduced by Marty in 1934 as a generalization of algebraic structures. Next, by associating fuzzy sets, Corsini introduced new notion in hyperstructures, that is fuzzy hyperstructures. After fuzzy hyperstructures introduced by Corsini, Cristea introduced the notion of intuitionistic fuzzy hyperstructures as a generalization of fuzzy hyperstructures. In 2023, Violeta-Fotea related the notion of fuzzy hyperstructures with genetic inheritance. Inspired by this research, this paper aims to find relation between fuzzy and intuitionistic fuzzy hyperstructures with chemical hyperstructures, that is to finding the fuzzy degree and intuitionistic fuzzy degree on chemical hyperstructures such as redox reactions, electrochemical cells, equilibrium reactions, and acid rain reactions.
