634 vertex-transitive and more than $10^{103}$ non-vertex-transitive 27-vertex triangulations of manifolds like the octonionic projective plane
Authors: Gaifullin Alexander Aleksandrovich
Published: May 2024

In 1987 Brehm and Kühnel showed that any combinatorial $d$-manifold with less than $3d/2+3$ vertices is PL homeomorphic to the sphere and any combinatorial $d$-manifold with exactly $3d/2+3$ vertices is PL homeomorphic to either the sphere or a manifold like a projective plane in the sense of Eells and Kuiper. The latter possibility may occur for $d\in\{2,4,8,16\}$ only. There exist a unique $6$-vertex triangulation of $\mathbb{RP}^2$, a unique $9$-vertex triangulation of $\mathbb{CP}^2$, and at least three $15$-vertex triangulations of $\mathbb{HP}^2$. However, until now, the question of whether there exists a $27$-vertex triangulation of a manifold like the octonionic projective plane has remained open. We solve this problem by constructing a lot of examples of such triangulations. Namely, we construct $634$ vertex-transitive $27$-vertex combinatorial $16$-manifolds like the octonionic projective plane. Four of them have symmetry group $\mathrm{C}_3^3\rtimes \mathrm{C}_{13}$ of order $351$, and the other $630$ have symmetry group $\mathrm{C}_3^3$ of order $27$. Further, we construct more than $10^{103}$ non-vertex-transitive $27$-vertex combinatorial $16$-manifolds like the octonionic projective plane. Most of them have trivial symmetry group, but there are also symmetry groups $\mathrm{C}_3$, $\mathrm{C}_3^2$, and $\mathrm{C}_{13}$. We conjecture that all the triangulations constructed are PL homeomorphic to the octonionic projective plane $\mathbb{OP}^2$. Nevertheless, we have no proof of this fact so far.

Published: May 2024

В контексте теории аналитической сложности рассмотрены две геометрические конструкции. Первая - на совокупности аналитических функций построена метрика, инвариантная относительно действия калибровочной группы. Вторая - получено необходимое дифференциально-алгебраическое условие принадлежности функции касательному пространству к классу функций двух переменных аналитической сложности не выше чем два в точке $z_0=x^3 y^2 +xy$. Этот результат позволил привести простой пример полинома степени пять, чья аналитическая сложность равна трем, а именно, $z=x^3y^2+xy + \pi x^2 y^3$.

Published: May 2024

This study analysed the determinants of household fish consumption in Enugu state, Nigeria; using 467 households selected through a multi-stage sample procedure. Data was collected using questionnaire and analysed using descriptive statistics such as frequency, percentages, and mean, and a logit regression model. The study results showed that azu fridge (mackerel) with the highest mean score (MS = 4.24) was the most consumed fish species in the form of fresh fish (MS = 4.56). The majority (64%) of the respondents indicated that they prepared their fish through the boiling method. The results of the logit regression analysis revealed that age, gender, marital status, education, income, household size, location, access to the market, and fish cost were statistically significant at various levels of percentages. In light of the findings, it is recommended that the government should consider these fish consumption determinants in the formulation of fish distribution and marketing policies to encourage its consumption in the state.
Effects of aerosol particles on precipitation and cloud parameters over East Africa-Ethiopia using MODIS satellite data: Part 01
Authors: Alemu Ambachew Abeje , Raju Jaya Prakash
Published: May 2024

The aerosol-cloud-precipitation interactions – ACPIs - are uncertain that show a large spatiotemporal variability in their magnitude. These things happen because of the effects of aerosol particles on precipitation and cloud parameters, environmental and meteorological conditions, industrial and agricultural influences, and other human influences and natural factors in each ecological functional area. For this study, aerosol and cloud data were retrieved from the Moderate Resolution Imaging Spectroradiometer MODIS sensors. These comprised of the aerosol optical depth AOD, Ångström exponent AET, atmospheric water vapor AWV, mean cloud fraction CFM, cloud top pressure CTP, and cloud top temperature CTT. Precipitation data is comprised of 3B43 products sourced from Tropical Rainfall Measuring Mission TRMM and the outgoing long-wave radiation OLR flux is comprised of Clouds and Earth‘s Radiant Energy System CERES satellite instruments. The study covers sixteen sites in East Africa-Ethiopia with neighboring countries - Eritrea, Djibouti, and South Sudan clustered into four regions for the periods of 2001–2022 to provide detailed information on the aerosol particles spatiotemporal effects on clouds and precipitation. The increase-decrease AWV, CFM and PPT fluctuations are with AOD opposing OLR, CTP and CTT. The parameters are oriented towards western part mostly in the southwest region of the study area. The minima values were found at the southeast cluster in 2022 for all AOD, AWV and CFM; in 2010 for PPT and OLR and in 1999 and for OLR with their maxima at northeast cluster in 2010 for AOD, AWV and CFM; in 2009 for PPT; and in 2011 and 2022 for CTP and CTT from both instruments. Accordingly, the AOD, AWV, CFM, PPT, CTP and CTT minimum values are 0.22, 1.90, 0.21, 1.15, 253.86, 504.53 and 257.73 for Terra and 0.18, 1.91, 0.27, 252.14, 533.43 and 262.94 for Aqua, and the maxima are 0.35, 2.33, 0.33, 2.26, 271.23, 619.08 and 268.49 for Terra and 0.35, 2.35, 0.41, 272.22, 640.07 and 272.58 for Aqua, respectively. The parameters OLR and AWV had the lowest optimum significant PCs at the Humera and Dahlak sites whereas the PCs retained based on AET at the Awassa site and AWV at the Dangote site were the highest. Differences in retained PCs point to different atmospheric dynamics responsible for the behavior of climate during various seasons of the year and the spatial coherence arising from both interannual and intraseasonal variability. And our observation using the HYSPLIT model and fire map confirms that transported aerosol particles in the atmosphere show varied source regions, mostly the Arabian desert and the southwest Indian ocean, at different levels.

Published: May 2024

The study’s surface water bodies, which include the lower Omo River and Lake Turkana in Ethiopia, are the most significant supplies of water for human activities, but they are also severely stressed by environmental factors and are in danger due to human activity. The physicochemical parameters were determined using standard analytical procedures in the Laboratory. The mean BOD5 values obtained in this study were 16.268± 1.47 mg/l and 16.28 ±1.133 mg/l in the upstream and in the downstream respectively. The COD value was higher in the River(upstream) (mean 376.06 ±130.45mg/L) than in the Lake (downstream) (mean 136.00± 41.52 mg/L).The mean fluoride ion level in the River were 0.89 ±0.0135 while that of the Lake was 2.026±0.064mg/l. The mean concentration of total nitrogen were 8.938±1.327mg/L) and 17.84 ± 4.0083mg/L) in River and Lake respectively .The value for PO4-3 was 1.866 ± 0.625mg/L in the River (LOR) while in Lake (ELT) , the concentration was 5.108±0.975mg/L . Mean concentrations for NH3 were 0.54 ±0.361and 1.354 ± 0.655 in the river and lake respectively. The finding of Water quality index (WQI) revealed that the water quality status was very poor and unsuitable for drinking in the lower Omo River and Omo Delta. Hence monitoring the effluent standards from the upstream industries, managing the waste disposal system in the towns along the river side are vital to protect the freshwater from further pollution.

Components of species diversity involves species richness and relative abundance within a biological community. Hence, this paper is set out to assess the relative abundance, richness and diversity of bottom sediment of macroinvertebrates in Okhuaihe River, Ikpe Community, Ikpoba Okha Local Government Area, Edo State, Nigeria, using standardized analytical techniques. Data obtained reveals that most of the metrics in the sediment samples fell within the tolerable ranges allowed by the Federal Ministry of Environment and the World Health Organization. Dipterans were the majority group among the twenty-eight (28) taxa that made up the 931 individuals collected, and an analysis of variance (ANOVA) showed no significant difference in the overall density (p > 0.05) between the sampling stations. Shannon (H) showed that Station 2 was more diverse (2.723) and least in Station 4 (2.496), while evenness (E) was highest in Station 2 (0.6342) and lowest in Station 3 (0.5248). Species richness as measured by Margalef’s index showed that Station 1 was highest (4.873) and least in Station 4 (3.99). There was a remarkable presence of Diptera, Coleoptera, Odonata, and Haplotaxida, while the nonappearance of sensitive species suggests possible contamination and pollution. Regular monitoring of the river’s sediment quality, including the activities and effluents that are discharged into the river is advised.

Published: May 2024

Quantitative phytochemical analysis of the leaf, stem bark and root of some antimalarial plants common in South-Western Nigeria was carried out. Results obtained showed the presence of tannins, alkaloids, flavonoids, terpenoids, saponins and phenolic acids in various concentrations in the different plant parts analysed. A high composition of phytochemicals was observed in the leaves, which confirms their frequency of usage in traditional medicine for the treatment of malaria. Of the various plants analysed, Mangifera indica leaves and stem bark had the highest tannin (176.3±1.5 mg/kg Garlic acid equivalents) and alkaloid (7350.3±2.5 mg/kg GAE) contents, respectively. Flavonoids were significantly highest (p<0.05) in the roots of Vernonia amygdalina (5055.0±3.0 mg/kg GAE). Terpenoid content was highest in the leaves of Khaya senegalensis and Psidium guajava (164.0±1.0 mg/kg GAE). Saponin content was generally low but was significantly highest (p<0.05) in the stem bark of Tithonia diversifolia (98,260.0±5.0 mg/kg GAE) while phenolic acid content was highest in the roots of Citrus paradisi (110.0±5.0 mg/kg GAE). All the plant parts analysed contained phytochemicals in various proportions, thus, justifying their use in traditional therapy and management of malaria disease.

Midy's Theorem in non-integer bases and divisibility of Fibonacci numbers
Authors: Masáková Zuzana , Pelantová Edita
Published: May 2024

Fractions $\frac{p}{q} \in [0,1)$ with prime denominator $q$ written in
decimal have a curious property described by Midy's Theorem, namely that two
halves of their period (if it is of even length $2n$) sum up to $10^n-1$. A
number of results generalise Midy's theorem to expansions of $\frac{p}{q}$ in
different integer bases, considering non-prime denominators, or dividing the
period into more than two parts. We show that a similar phenomena can be
studied even in the context of numeration systems with non-integer bases, as
introduced by R\'enyi. First we define the Midy property for a general real
base $\beta >1$ and derive a necessary condition for validity of the Midy
property. For $\beta =\frac12(1+\sqrt5)$ we characterize prime denominators
$q$, which satisfy the property.

LITERARY REVIEW OF PINDI(POULTICE) KRIYAKALPA IN NETRA ROGA
Authors: Shivaji Maske Snehal , Virkar Chandana
Published: May 2024

The great Ayurvedic Acharya mentioned in the Samhita: "Sarvendriyanam Nayam Pradhanam". The eye is the
most critical organ, and it is essential to maintain eye health and effectively alleviate possible disorders. The
Acharyas described detailed local treatments for managing and treating eye diseases using simple but effective
methods called "Kriyakalpa". Kriyakalpa is a treatment method that refers to procedures where drugs/medications
are used in or around the eyeball as a method of therapy. Kriyakalpa has more advantages over oral drug administration because it allows more time for bioavailability. Modern science also uses drug absorption through the
skin and is considered an effective method of drug delivery, since Pindi(poultice) is the modified procedure of
Bidalaka, and also follows the same route. This article discusses the literary review, mode of action and significance of Pindi(poultice) in Netra Rogas.

TWO FACES OF FEAR IN STORIES FOR CHILDREN BY PREŽIHOV VORANC, IVO ZORMAN, AND JANJA VIDMAR
Authors:   University of Kragujevac, Faculty of Education in Užice, Serbia, STAKIĆ Mirjana M.
Published: May 2024

The paper investigates the phenomenon of fear in stories for children from the corpus of Slovenian literature. The subject of analysis involves three stories written by Slovenian authors Prežihov Voranc, Ivo Zorman, and Janja Vidmar. The results show that in each of the analyzed stories, two sides of fear are revealed: the primary, which is related to its visualization and/or sensory perceptions it causes, and the secondary, indirect one, which depends on the sociological or psychological factors that, on the one hand, cause fear, but on the other, can also help one free oneself from it. In addition, the analysis shows the presence of stereotypes in the thematization of fear, in the dismantling of which lies an educational solution for overcoming fear, as well as in the possible procedure of lexical nomination and semantic denotation which would deprive fear of its abstractness. The conclusions indicate the need to demystify the source of fear, as well as the need for further research in this area.

We consider the wave equation with a locally damping and a nonlinear source term in a bounded domain. ytt − Δy + a(x)g(yt) = |y|p−2y, where p > 2. The damping is nonlinear and is eﬀective only in a neighborhood of a suitable subset of the boundary. We show, for certain initial data and suitable conditions on g,a and p that this solution is global we use the Faedo-Galerkin method. Also we established the exponential decay of the energy when the nonlinear damping grows linearly by introducing a suitable Lyapunov functional.

Suppose G is a graph with the vertex set V (G). A set D ⊆ V (G) is a total k-dominating set if every vertex v ∈ V (G) has at least k neighbours in D. The total k-domination number γkt(G) is the size of the smallest total k-dominating set. When k = 2 the total 2-dominating set is referred to as a double total dominating set. In this work we compute the exact values for double total domination number on H-phenylenic nanotubes HPH(m,n), m,n ≥ 2 and H-naphtalenic nanotubes HN(m,n), n = 2k, m,n ≥ 2. As all vertices have a degree 2 or 3, there is no total k-domination for k ≥ 3 for H-phenylenic and H-naphtalenic nanotubes, and the double total domination is the maximum possible.

A large number of patient health data is collected daily in medical information systems. This data contains a non-structural part written in natural language that contains the physician’s notes on specific characteristics of the patient’s medical condition. This section may contain symptoms, diagnoses, therapies, specialties, Latin terms, and other words specific to the medical domain. Useful information suitable for various analyzes could be extracted by processing this section of the text. There are no electronic lexical resources in the Serbian language that are suitable for normalizing and extracting knowledge from medical texts, as well as methods for marking terms in this domain. One reason is that, before any method is applied, the de-identification of patients and staff must be ensured. Also, the evaluation of the results requires manually marked corpora of medical reports in the Serbian language. This paper proposes a method for identifying words belonging to diagnoses in medical texts written in Serbian using natural language processing (NLP) techniques. The proposed method is based on the use of lexical resources, and two set of 1000 medical reports are manually marked for research purposes. In the experimental part, the results of automatic labeling of diagnoses on the marked corpus using the proposed method are presented.

This issue's In-Dialogue represents the intentional epitomization of many conversations the Editorial Team has been having since JASC’s inception around what we mean by 'transformative'. As convenors of the dialogue Oliver Koenig and Megan Seneque invited  a small group of individuals who, in their ongoing work, have been deeply immersed in exploring research and praxis paradigms that respond ethically, critically, and creatively to the intersecting crises of our time. Together, the group set out to explore the integrity of 'research' and 'practice', their critical entanglement and co-dependence, and the nature of practices that enable worlds to be created in certain ways. Rather than attempting to arrive at a consensual understanding, the dialogue that unfolds can be seen as a mirror of the world-making practice(s) that are characteristic of transformative research

Published: May 2024

Mexico has a developing biodiesel market. Although the international trend of production and consumption has increased over the last decade, the quantities produced in the country are still minimal compared to those of petrodiesel. To understand the reasons why Mexico has an under-exploited and under-utilized market, this work describes the current demand situation with a theoretical proposal of a model that responds to seven explanatory variables of its behavior: price of biodiesel, price of petrodiesel as a substitute good, price of petrodiesel as a complementary good, income of the population, number of transports with a functional diesel engine, certifications, and the availability of the product in the supply chain. The lack of regulation regarding the norms for the production, handling, transport, and disposal of this type of biofuel means that there is still no defined biodiesel market in Mexico, which means that most biodiesel production is destined for self-consumption or informal retail sales, which means that the product does not have a defined supply chain in the country.

Water availability is a function of climatic and land surface conditions, which determine the amount and distribution of atmospheric water as it reaches the surface. This largely depends on rainfall, whose variability affects water, food and livelihood security. This paper sought to quantify the effects of rainfall variability on water availability in an effort to support effective water resources management. Coefficient of Variation (CV), Standardized Anomaly Index (SAI) and Mann-Kendall trend test approaches were used to assess variability and trends, while correlation and regression analysis were employed to determine effects of rainfall variability on streamflow. A hydrological model, Soil and Water Assessment Tool (SWAT), was used to simulate streamflow with a view to assessing water availability under two climate change scenarios; Representative Concentration Pathways (RCP) 4.5 and 8.5. Results show that the area experiences moderate to extreme rainfall variability, as indicated by CV and SAI values that ranged from 20 to 99% and -2.5 to +3 respectively, resulting in moderate to extreme floods and droughts that often disrupt livelihoods. Current streamflow simulations (1981 – 2020) indicated increasing trends. Near and far future streamflow volumes will decrease by 15% during the April-May-June season while during October-November-December season they will increase by 13%, compared to the present. Increasing trends of rainfall and streamflow indicate that the area has opportunities for rainwater harvesting while the high variability indicates a need for early warning systems to cushion communities from climatic shocks evidenced by the impacts of climate extremes experienced in the area.

The advancement of technology, including the use of Artificial Intelligence (AI) in everyday life, has brought about significant changes and substantial impacts, especially in electronic transactions and law. While the use of AI promises various benefits, it also raises several important legal issues, such as legal responsibility, data privacy, and contract validity. The purpose of this research is to understand the legal framework of AI in the Indonesian legal system and the legal implications of AI utilization, particularly in the context of electronic transactions. This research is of a normative juridical type, employing a conceptual approach and a statute approach. The results of the research indicate that AI is not specifically regulated in its own law but is discussed within the Electronic Information and Transactions Law (ITE Law) and several regulations under it. The legal implications of AI usage can be viewed from two main perspectives. First, AI is regarded as an electronic agent, where all legal responsibilities for AI actions are placed on the electronic system providers. Second, AI is seen as a legal subject, where it is treated as a legal entity or rechtpersoon.

Authors:   Hyderabad, India, Amballa Durga Prasad
Published: May 2024

Online symptom checkers have emerged as valuable tools for individuals seeking health advice and guidance. Powered by artificial intelligence (AI) algorithms, these symptom checkers aim to provide more accurate and personalized health assessments, directing users to the appropriate level of medical care. This study presents an innovative architecture that combines Vector Database (VDB), Faiss similarity search algorithm, and GPT (Generative Pre-trained Transformer) API to analyze user inputs, identify intents, and generate tailored responses. The proposed system leverages the power of VDB to store symptom and test data as embeddings, enabling efficient similarity searches. The GPT model is employed to analyze user inputs, determining whether the user is seeking symptom analysis, test suggestions, booking details, booking help, or general health queries. Based on the identified intent, the Faiss algorithm searches for relevant tests and returns appropriate recommendations. The GPT model then generates personalized responses by considering the user's input, suggested tests, intent, and a summary of the chat history. The chatbot also incorporates a memory mechanism to store conversation summaries, providing context for subsequent interactions. Experimental results demonstrate the effectiveness of the proposed architecture in delivering accurate and context-aware health advice, guiding users to the most suitable medical care options. This study highlights the potential of AI-powered online symptom checkers in improving healthcare accessibility, reducing unnecessary medical visits, and empowering individuals to make informed decisions about their health.
