Authors: Tang Liwen
Published: April 2024

In order to deeply study the sustainability of water resources in Sichuan Province, this study aims to explore the spatial distribution characteristics of the ecological footprint of water resources in Sichuan Province. Using data from the Sichuan Water Resources Bulletin and Statistical Yearbook from 2011 to 2019, the spatial and temporal distribution characteristics of the ecological footprint of water resources in Sichuan Province and its cities and states were evaluated by constructing the ecological footprint model of water resources and the three-dimensional ecological footprint model. It was found that the EFw, ECw and 10,000 yuan GDP of Sichuan Province peaked in 2011 and stabilized between 2012 and 2019; meanwhile, the WESI showed significant instability. In terms of ecological footprint distribution, Sichuan province is mainly biased towards agriculture. Chengdu city has a more significant water consumption than other cities and states due to the special characteristics of tourism and population structure. Ganzi and Aba are relatively better than other cities and states in terms of water sustainability due to geography, population and economic structure. In summary, the changes in the ecological footprint of water resources in Sichuan Province and its cities and states between 2011 and 2019 show obvious regional differences. Therefore, in order to enhance the sustainability of global water resources, in addition to the need for macro-control at the national and provincial levels, it is necessary to implement precise management strategies for individual cities and states.

Authors: Urbina Romo Nancy Yolanda , Sánchez Álvarez Daniel Alejandro , Solís Sánchez María Ilusión
Published: April 2024

Asherman's syndrome is a condition characterized by the presence of uterine adhesions or uterine synechiae that are caused by unintentional trauma, severe infections or endometrial hypoxia in a pregnant uterus. The aim of the study was to identify the main risk factors and diagnostic alternatives for Asherman's syndrome through literature review. In an effort to better understand Asherman's syndrome, a descriptive documentary study reviewed articles published from 2019 to 2023 in high-impact journals, selecting 17 for analysis. These included case studies and theoretical sources, highlighting the still unknown pathophysiology of the syndrome. It was confirmed that diagnosis is mainly based on hysterosalpingography and hysteroscopy, although these methods do not guarantee complete endometrial recovery, leading to high recurrence rates and low conception success rates. This underscores the need for complementary therapies to restore the uterine cavity and prevent new adhesions. In addition to the medical challenges, the study highlights the significant emotional and psychological impact of the syndrome, underscoring the importance of emotional and psychological support for those affected, as well as the need to raise awareness and support research to improve their quality of life. In conclusion, partial or total obstruction of the uterine cavity by adhesions is noted as a risk, emphasizing the need for a multidisciplinary approach to treatment. The study highlights the absence of clinical guidelines and awareness in Ecuador, which hinders the management of this condition

Authors: Abakah Fitzgerald , Antwi Albert
Published: April 2024

In this case study, the efficacy of experiential learning for solving 3-dimensional problems in trigonometry was tested. The study involved two groups of students in grade 12 at a high school in South Africa, the control (n=35) and the experimental (n= 37). The control group was taught via the traditional approach, whilst the experimental group was taught using experiential learning in a collaborative classroom setting. Kolb’s experiential learning theory was applied as the theoretical framework and data was collected through pre- and post-tests. The pre-test and post-test scores for both groups were analysed using the mixed-effects negative binomial model and from the results it was established that experiential learning resulted in significant improvements in participants' performance compared to the traditional method. Therefore, the researchers concluded that experiential learning is an effective instructional approach, thus, recommending this mode of pedagogy for solving 3-dimensional problems in trigonometry.

Authors: Souleymane Zio , Bernard Lamien  , Mohamed Beidari  , Tougri Inoussa
Published: April 2024

Real-time monitoring of groundwater pollutants is very challenging to implement due to the difficulty and high economic cost. Groundwater numerical modeling is generally used as an alternative to create protection systems and illustrate their effectiveness. Several groundwater simulation software programs are available, however, they are based on numerical methods that require high spatial and temporal meshing, which considerably increases their computational costs and limits their use for optimization process.To solve this problem, a methodology that combines machine learning techniques based on neural networks, flow, and transport equations in underground reservoirs is proposed. This method is known as physics-informed deep neural networks, abbreviated as PINN. In this work, we will show the performance of PINN in predicting the flow and transport of pollutants in an underground reservoir. To evaluate the effectiveness of the PINN, the finite element method with a fine mesh grid is used as a reference solution to validate the PINN results.The results show that PINNS provide very good result in predicting pollutant transport in the reservoir with a relatively low cost.
Weighted Eulerian extensions of random graphs
Authors: Ganesan Ghurumuruhan
Published: April 2024

The Eulerian extension number of any graph H (i.e. the minimum number of edges needed to be added to make H Eulerian) is at least t(H), half the number of odd degree vertices of H. In this paper we consider weighted Eulerian extensions of a random graph G where we add edges of bounded weights and use an iterative probabilistic method to obtain sufficient conditions for the weighted Eulerian extension number of G to grow linearly with t(G). We derive our conditions in terms of the average edge probabilities and edge density and also show that bounded extensions are rare by estimating the skewness of a fixed weighted extension. Finally, we briefly describe a decomposition involving Eulerian extensions of G to convert a large dataset into small dissimilar batches.
Acyclic and tree unique colourings in random graphs
Authors: Ganesan Ghurumuruhan
Published: April 2024

In this paper we study acyclic colouring in the random subgraph G of the complete graph Kn on n vertices where each edge is present with probability p, independent of the other edges. We show that unlike the ordinary chromatic number, the acyclic chromatic number exhibits a phase transition from sub-linear to linear growth as the edge probability increases, even in the sparse regime and obtain estimates for the critical exponent. We show that allowing for a small relaxation in the acyclic colouring condition allows for sublinear growth for all values of the edge probability exponent. We also study a generalization of unique colourings where we impose the condition that at least one vertex in any copy of a given tree has a unique colour and obtain bounds for the minimum number of colours needed for such a colouring.
Gleason-Kahane-Zelazko Theorem in Jordan Banach algebras
Authors: Maouche Abdelaziz
Published: April 2024

We review the celebrated Gleason-Kahane-Zelazko and Kowalski-Slodkowski theorems from the setting of associative Banach algebras to the wider class of nonassociative Jordan Banach algebras. We introduce the notion of almost multiplicative linear functionals in Jordan Banach algebras and prove a theorem extending a former result of B.E. Johnson for Banach algebras by employing the more recent concept of condition spectrum. We show how to rediscover the Gleason-Kahane-Zelazko theorem for Jordan Banach algebras from the corresponding version for almost multiplicative linear functionals.

Niho bent functions and ovals are listed up to equivalency for dimensions m ≤ 6. They are described by means of g-functions. We also give characterization of supports of Niho bent functions and their duals in terms of associated ovals.
Evolution algebras that are almost Jordan
Authors: Ouedraogo Sidmanagde Emile , Savadogo Souleymane , Conseibo André
Published: April 2024

In this paper, we give a necessary and sufficient condition for an almost Jordan algebra, which is also called Lie triple algebra to be an evolution algebra. We study the nilpotency, power associativity of such algebras. We specify the necessary and sufficient conditions for such an algebra to be baric. Along the way we show that train evolution algebras which are almost Jordan algebras are of rank at most 5. We prove that any finite-dimensional non-nil-evolution algebra verifying the identity of almost Jordan algebras has at least one non-zero idempotent. Finally, we study the derivations of this class of algebras.
Hyperbolic Augmented Lagrangian algorithm for multiobjective optimization problems
Authors: Tougma Appolinaire , Kaboré Augustin , Somé Kounhinir
Published: April 2024

In this article, we propose an adaptation of the Hyperbolic Augmented Lagrangian algorithm to solve multiobjective optimization problems. After conducting a literature review, we provide a definition of the Hyperbolic Augmented Lagrange method. Under clearly defined assumptions, we demonstrate that any limit point of a sequence generated by the proposed approach is feasible and constitutes a Pareto-optimal solution. To assess the effectiveness of the proposed algorithm, we incorporate two variants of the Broyden-Fletcher-Goldfarb-Shanno (BFGS) method, thereby offering two approaches for solving well-known tests problems from the literature. We employ metrics to evaluate the performance of these two approaches.
Self-switching of union of two complete graphs
Authors: Jayasekaran C. , Athithiya S. S.
Published: April 2024

By a graph H = (V, E), we mean a finite undirected graph without loops and multiple edges. Let H be a graph and σ ⊆ V be a non–empty subset of V. Hσ is the graph obtained from H by removing all edges between σ and its complement V-σ and adding as edges all non-edges between σ and V-σ. Then σ is said to be a self-switching of H if H ≅ Hσ. It can also be referred to as k-vertex self-switching where k = |σ|. The set of all self-switchings of the graph H with cardinality k is represented by SSk(H) and its cardinality by ssk(H). A graph on m vertices in which each pair of distinct vertices are neighbors is called a complete graph and is denoted by Km. Km∪ Kn is the union of two complete graphs and is disconnected. In this paper, we give necessary and sufficient conditions for σ to be a self-switching for the graph H=Km ∪ Kn and using this, we find the cardinality ssk(H).
A well-defined Godunov-type scheme in a Navier-Stokes model with a friction term
Authors: Ouya Jules , Ouedraogo Arouna
Published: April 2024

In this paper, particular attention is paid to Godunov-type numerical scheme for solving partial differential equations. We numerically approximate the weak solutions of the Navier-Stokes problem in the compressible case in one dimension of space with a friction term. The solutions of this model exhibit various properties that must be maintained accurately through numerical methods. Indeed, the solutions may satisfy stable regimes, the scheme mush maintain positive density throughout the flow. By developing a suitable approximate Riemann solver, a finite volume method is formulated to preserve as well as possible (or even exactly) those steady states of particular physical interest. Numerical simulations illustrate the effectiveness of the suggested computational method.
Modified VIM for wave equations
Authors: Fatima Nahid
Published: April 2024

During the past few years, there has been a significant amount of interests in the Variational Iteration Method (VIM), which is a method that is utilized for the purpose of solving nonlinear differential equations. Minor adjustments have been made to ‘VIM as part of the Modified Variational Iterative Method (MVIM)’. For a specific type of nonlinear differential equation, the implementation of the MVIM method results in unnecessary calculations and additional time spent on repeated calculations for series solutions. The drawbacks of VIM are addressed by introducing a modified version, and its usefulness is demonstrated through a few examples.

Published: April 2024

Anxiety and depression are two psychological illnesses that are linked to chronic obstructive pulmonary disease (COPD). In Saudi Arabia, no research has been done on the prevalence of psychological disorders among patients with COPD and their association with COPD severity. This study aims to screen for anxiety and depression among Saudi patients with COPD and to explore the impact of COPD severity on the patients’ psychological status. In this cross-sectional study, we recruited 70 stable patients with COPD from outpatient respiratory clinics. Anxiety and depression were evaluated using the Anxiety Inventory for Respiratory Disease (AIR) scale and Patient Health Questionnaire-9 (PHQ-9). The AIR identified that 46% of patients with COPD had anxiety and the PHQ-9 identified that 60% had depression. Patients with severe COPD stages were at greater risk of anxiety [AIR odds ratio (OR) = 2.54, 95% confidence interval (CI): 2.31-2.86] and depression (PHQ-9 OR = 3.08, 95% CI: 2.76-3.45). Patients with severe COPD stages are at increased risk of both anxiety and depression compared to patients with less severe COPD stages.
Silica Based Mesoporous Materials as Sorbents for Solid-Phase Extraction of Organic Pollutants in Water
Authors: Dolores Gil García María , Martínez Galera María , Jesús Martínez Bueno María
Published: April 2024

Since the first applications of solids with adsorbent properties in water treatment, Solid-Phase Extraction (SPE) has been the most suitable sample preparation technique for the determination of organic pollutants in water. In the last decades, numerous articles have appeared in the literature describing a wide variety of SPE sorbents. Attention in this field has focused on the search for new SPE materials capable of extracting a wide variety of pollutants from water. However, each sorbent has advantages for certain compounds, but not when it is used with others. Thus, conventional sorbents showed poor performance for most high polarity analytes. Recently, mesoporous materials are attracting increasing interest in sample preparation due to their desirable characteristics. They present unique advantages as highly ordered and size-controlled mesoporous structures, high surface areas and large pore volumes, good performance in thermal and chemical stability, compositional controllability and flexibility for functionalization.

An Impact of Social Marketing on Smoking and Tobacco Consumption
Authors: Kansal Ruchi , Ahmed Mahtab
Published: April 2024

The paper discusses the role of social marketing in preventing health-related harmful habits such as tobacco consumption and smoking. These habits are the causes of deadly diseases such as lung cancer, tuberculosis, and other chronic infections which are detrimental to life of the people. Children fall prey to the wrong habits in the wrong company and become tobacco addicts. So many cases of teen drug addicts are reported in a large number. They have a lack of conscience at a tender age and negligence of their counselling and awareness increases the number of smokers, drunkards, and drug addicts. Once they are afflicted with the diseases they must run for medicines and treatment. Therefore, it should be prevented before suffering as the saying goes, “Prevention is better than cure “. They are unaware that they are prevented not only by clinical treatment and medicines but also by social awareness and education. Social mobilization of the people through awareness programs, education, camps, campaigns, etc. is known as social marketing. The significance of social marketing is its effects on the prevention of physically detrimental habits in the youth which contributed a lot to the reduction of cases of diseases. The role of government programs, educational and medical institutions, social workers, and NGOs is worth applauding in India which undertake and complete projects, organize awareness camps, and educate parents and youths to save themselves from the consumption of harmful substances. It has also produced good output in India that the cases of smoking and drug addiction have reduced to support the country’s development as India is advancing towards becoming the third largest economy and a developed country by 2030 and 2047 respectively.

Participants submitted data from up to 50 primary cases during the study period. Participants reported ER, PgR, and HER2 results in addition to demographic and histologic information. Participants also provided annual institution-level expression rates.

Results.—

A total of 21 institutions submitted data for 687 cases. Aggregate positivity rates for ER and PgR were 85.6% and 75.1%, respectively. Receptor positivity rates were higher in well-differentiated (grade 1) tumors (ER, 97.4%; PgR, 88.0%) compared with moderately differentiated (grade 2) tumors (ER, 92.4%; PgR, 84.0%) and poorly differentiated (grade 3) tumors (ER, 61.8%; PgR, 48.0%). Expression rates were higher in postmenopausal women (ER, 87.2%) than premenopausal women (ER, 79.6%) and higher in lobular carcinomas (ER, 98.7%; PgR, 85.3%) than ductal carcinomas (ER, 84.1%; PgR, 74.5%). The aggregate HER2 positivity (score 3+) rate was 9.0%. The aggregate HER2 equivocal (score 2+) rate was 14.5%. Of 81 equivocal (score 2+) cases, 70 (86.4%) were nonamplified.

Conclusions.—

The data from this study provide multi-institutional benchmark data to assist laboratories performing periodic comparisons as part of a quality management program. Overall expression rates were generally similar to those of other published reports, with the exception of the ER-negative and HER2-positive rates, both of which were somewhat lower.

Isolatation, authentication and evaluation of symbiotic effectiveness of elite indigenous rhizobia nodulating phaseolus vulgaris l. in Hai district, Northern Tanzania
Authors:   , Namkeleja Yusuph
Published: April 2024

Phaseolus vulgaris L. production in Sub Saharan Africa is affected by nitrogen deficiency in the soils. Rhizobium inoculants are considered as the best solution to curb the problem of soil nitrogen deficiency. However, accessibility of rhizobia inoculants in most African countries is a challenge, hence leads to most inoculants being imported from abroad. The estimation of the number of indigenous rhizobia nodulating P.vulgaris in the soils of Hai District, northern Tanzania as well as isolation, authentication and evaluation of the symbiotic effectiveness of those indigenous rhizobia strains was conducted. The most probable number infection method was used to estimate the population of indigenous rhizobia in the soils. Yeast Extract Manitol Agar containing Congo red was used to grow the isolated rhizobia strains. Koch’s postulates were employed in authentication, while the number of nodules per plant, chlorophyll content and other plant growth parameters was used to test effectiveness of the isolated strains. The Shapiro Wilk’s W test was used for testing normality of the data, one way ANOVA and Kruskal-Wallis Rank sum test was used for analysis of the data which are normally distributed and those which are not normally distributed respectively while Fisher’s Least Significant Difference were used as a post hoc significance test. The 61% of the soil in the study area had low rhizobia populations (<100 cells g-1of soil). Moreover, 18 bacterial strains were isolated and proved to be rhizobia.
Proposições entre o Ensino da Dança e as Teorias dos Movimentos Sociais

Published: April 2024

Este estudo dançante/educativo tem como objetivo aproximar as teorias dos Movimentos Sociais e processos de ensino-aprendizagem em Dança. O ensaio traz reflexões recentes que estamos desenvolvendo em diálogo com experiências autobiográficas, narrativas de si que articulam vivências como estudante e artista/educador. Desse modo, organizamos o escrito em duas sequências de movimentos que foram nomeadas como: (1) Perspectivas históricas das Metodologias para o Ensino da Dança e (2) Tensionamentos dos processos de ensino-aprendizagem em Dança com as Teorias dos Movimentos Sociais e Educação. Nesse processo, observamos a potencialização da dimensão política da Dança, o que reafirma a necessidade de evidenciar seu compromisso social e revisitar suas práticas criticamente.
Maracatucá?! Maracatu!:
Authors: Santos Wagner Leite dos , Barbozza da Silva Alexsander
Published: April 2024

O presente texto tem como objetivo compreender o impacto do Ensino da Dança com o Cortejo de Maracatu desenvolvido na Escola Municipal Padre Leonel da Franca, com turmas do Ensino Fundamental (anos iniciais), no segundo semestre de 2022. Desse modo, organizamos este escrito em dois batuques: (1) A cultura afro-brasileira e os documentos da educação do Ensino Fundamental (anos iniciais) da Paraíba, e (2) Os processos de ensino-aprendizagem em Dança e o Cortejo de Maracatu. Em seguida, refletimos acerca da experiência com as práticas pedagógicas em dança, no Cortejo de Maracatu. Com a efetivação deste estudo, acreditamos que a inserção dessa manifestação negra na instituição de educação formal pode indicar caminhos para pensarmos tanto numa Eduação Antirracista em Dança, como no enfrentamento ao imaginário social, o qual restringe às pessoas negras a trajetória violenta da escravização.

Corpos, culturas e danças:
Authors: Ricardo Marinelli Princesa
Published: April 2024

A presente investigação tem como norte tratar das possibilidades de inserção da arte de dançar na educação formal a partir da fruição artística. Neste sentido, o objeto do estudo se constrói a partir das relações entre algumas acepções de Dança contemporânea, ensino de Dança na Escola, Culturas — da escola, na escola e escolar —, arte e experiência estética. Identificou-se o apreciar artístico como significativa válvula em que a comunidade escolar tem a possibilidade de entrar em contato com a beleza que existe naquilo que é plural, naquilo que não está obrigatoriamente cedendo aos modelos encarados como ideais.
