Global dynamics of a simple model for wild and sterile mosquitoes
Authors: Ichida Yu , Nakata Yukihiko
Published: September 2024

There are known methods to manage the population dynamics of wild and sterile mosquitoes by releasing genetically engineered sterile mosquitoes. Even if a two-dimensional system of ordinary differential equations is considered as a simple mathematical model for developing release strategies, fully understanding the global behavior of the solutions is challenging, due to the fact that the probability of mating is ratio-dependent. In this paper, we combine a geometric approach called the time-scale transformation and blow-up technique with the center manifold theorem to provide a complete understanding of dynamical systems near the origin. Then, the global behavior of the solution of the two-dimensional ordinary differential equation system is classified in a two-parameter plane represented by the natural death rate of mosquitoes and the sterile mosquito release rate. We also offer a discussion of the sterile mosquito release strategy. In addition, we obtain a better exposition of the previous results on the existence and local stability of positive equilibria. This paper provides a framework for the mathematical analysis of models with ratio-dependent terms, and we expect that it will theoretically withstand the complexity of improved models.
Existence of a unique solution to a fourth-order boundary value problem and elastic beam analysis
Authors: Rao Ravindra , Mohan Jonnalagadda Jagan
Published: September 2024

We study the existence and uniqueness of solutions to a particular class of two-point boundary value problems involving fourth-order ordinary differential equations. Such problems have exciting applications for modeling the deflections of beams. The primary tools employed in this study include the application of Banach's and Rus's fixed point theorems. Our theoretical results are applied to elastic beam deflections when the beam is subjected to a loading force and both ends are clamped. The existence and uniqueness of solutions to the models are guaranteed for certain classes of linear and nonlinear loading forces.
Novel stability criterion for DNNs via improved asymmetric LKF
Authors: Zheng Xianhao , Wang Jun , Shi Kaibo , Tang Yiqian , Cao Jinde
Published: September 2024

This paper briefly proposes an improved asymmetric Lyapunov-Krasovskii functional to analyze the stability issue of delayed neural networks (DNNs). By utilizing linear matrix inequalities (LMIs) incorporating integral inequality and reciprocally convex combination techniques, a new stability criterion is formulated. Compared to existing methods, the newly developed stability criterion demonstrates less conservatism and complexity in analyzing neural networks. To explicate the potency and preeminence of the proposed stability criterion, a renowned numerical instance is showcased, serving as an illustrative embodiment.

Authors: Seneviratne Thilanka , Somaratne Kosala , Brabaharan Subhani , Bandara Dilan , Alahakoon Thilini , Senevivickrama Priyanka , Kumarasiri Ranjith
Published: September 2024

Background: Allergens are known trigger factors for exacerbations of atopic dermatitis (AD). Skin prick test (SPT) and serum specific IgE (SSIgE) test are standard diagnostic tools to establish allergen sensitivities. Comparatively, SSIgE is costly, needs special laboratory facilities, involves taking serum samples (difficult in children) and it takes time to get reports. SPT is relatively inexpensive and results are available immediately.Objectives: To compare the results of SPT and SSIgE to detect allergen sensitivity in paediatric patients with AD.  Method: Patients with AD were recruited from specialised dermatology clinics at Sirimavo Bandaranayake Specialised Children’s Hospital and National Hospital Kandy, Sri Lanka from June 2019 to March 2020. Sensitization to house dust mite (HDM) species Dermatophagoids Pteronyssinus (HDM-DP), cat epithelia (CE), cow’s milk (CM), egg white (EW), Aspergillus fumigatus (AF) was checked using SPT and SSIgE. SSIgE assessed with Immunocap method, >15 kU/L was taken as positive. In SPT, a wheal =3mm than the negative control was taken as positive.Results: Fifty-two patients were involved in the study. HDM-DP was positive in 51.9% with SPT while 50% were positive with SSIgE; 15.4% tested positive for CE with both SPT and SSIgE. There was a highly significant correlation between SPT and SSIgE for HDM (p<0.001). A significant correlation was also seen for CE (p=0.011). AF, CM, and EW did not show a significant correlation. Conclusions: SPT and SSIgE showed significant correlation in relation to HDM and CE sensitivity.

Topology of the Liouville foliation in the generalized constrained three-vortex problem
Authors: Palshin Gleb Pavlovich
Published: September 2024

We consider a completely Liouville integrable model of Hamiltonian mechanics with two degrees of freedom. This model describes the motion of two point vortices with a third vortex fixed at the origin. This problem covers, as a particular case, the problems of the motion of hydrodynamic vortices in an unbounded perfect fluid and magnetic vortices in a ferromagnetic medium. We study the topology of the Liouville foliation of this system using the bifurcation diagram of the momentum map. We prove some results on the general form of the bifurcation diagram and discover some properties of critical trajectories in the inverse image of its bifurcation curves. Using these results we show the presence of two important bifurcations of Liouville tori passing through a singular leaf of the form $\mathbb S^1 \times (\mathbb S^1 \dot{\cup} \mathbb S^1 \dot{\cup} \mathbb S^1)$. In the first case one Liouville torus bifurcates into three tori when passing through the singular leaf; in the second case two tori bifurcate into two tori.

Published: September 2024

Cockayne syndrome (CS) is a rare, severe, genetic neurodegenerative disorder. To better understand the condition, this article aimed to discuss the clinical manifestations and prognosis of CS. This clinical study was a retrospective review of the medical records of patients diagnosed with CS between January 2010 and January 2020. A total of 9 patients (6 males, 66.7%; 3 females, 33.3%) from 7 families were enrolled in the study. The median age of the patients was 94 (4-186) months. Genetic confirmation of CS was obtained in 5 of the patients and ERCC8 mutations were identified in all patients who underwent genetic confirmation of the disease. On admission, 8 patients were found to have microcephaly 4 patients were admitted for psychomotor retardation, 3 for seizures, and two for walking disabilities. The diagnosis of patients with CS can be challenging due to the wide range of symptoms. In patients who are normal at birth but develop microcephaly during follow-up, physicians should consider CS in addition to metabolic diseases in the differential diagnosis.

Authors: Mawouma Saliou , Mbadji Moussa , Noubangomde Nangtobert , Bandiang Prosper Houvounsassou , Djerassem Charles Ndilyam
Published: September 2024

Despite the established inhibitory action of tea polyphenols on dietary iron absorption, the consumption of tea at mealtimes remains  common in many regions of the globe where anaemia is still a public health concern. The objective of this study was to investigate the  effect of acidulating black tea with citric acid or lime juice on dietary iron bioaccessibility. Firstly, the effect of citric acid on iron- polyphenol complex formation and iron speciation was studied using molecular spectrophotometry. Then, the bioaccessibility of dietary  iron from pearl millet ball in the presence of black tea acidulated with citric acid or lime juice was assessed through a simulated in vitro  digestion. Finally, the different species of bioaccessible iron were quantified. Citric acid reduced the absorbance of iron-polyphenol  complex by 58.06% and 59.52% at pH 5 and 7, respectively, while promoting the formation of organic iron at pH 5 and ferrous iron at pH 5  and 7. Dietary iron bioaccessibility increased in the presence of acidulated black teas, with the greatest variation (28.57%) being  observed in the digest of pearl millet ball mixed with lime juice-acidulated black tea. The more abundant bioacessible iron species was  organic iron, and ferrous iron was more concentrated in digests of pearl millet ball mixed with lime juice-acidulated black tea. Acidulation  of tea beverage with lime juice is a culinary technique that could mitigate the inhibitory action of tea polyphenols on dietary iron  absorption and alleviate iron deficiency in populations consuming tea at mealtimes.

Published: September 2024

Les écosystèmes forestiers font face à des défis de conservation malgré leur rôle important dans la fourniture des services  écosystémiques, et la conservation de la biodiversité. L’objectif de cette étude était d’évaluer la diversité et l’importance des services  écosystémiques fournis par le Chantier d’Aménagement Forestier (CAF) de Tiogo. Des entretiens individuels semi-structurés et de  groupes ont été menés auprès de 100 personnes dans 7 villages de la zone d’influence du CAF. La fréquence de citation, la valeur d’usage  et le facteur de consensus informateur ont été utilisés pour apprécier l’identification des services fournis par les populations. Au  total 34 services écosystémiques regroupés en 5 catégories ont été recensé. Un cortège de 33 espèces ligneuses ont été mentionnées  par les populations locales comme rendant des services d’approvisionnement. L’âge, le sexe et la position géographique  du village étaient perçus comme des facteurs déterminants l’identification des services. Les personnes âgées en général les femmes,  avaient des connaissances plus spécifiques que les hommes. Malgré son importance socio-économique et écologique, le CAF subit  diverses pressions et bénéficie très peu de mesures de conservation. Cette étude souligne l’importance de développer des stratégies de  conservation adaptées, telles que l’agroforesterie et la reforestation.

Au Burkina Faso, outre les plats cuisinés, la salade et les grillades sont fortement consommées dans la rue. Leur préparation entraine une  utilisation du vinaigre ou des succédanés de vinaigre dans le but d’améliorer la qualité organoleptique des mets. L’objectif de cette  étude était de déterminer la typologie, les caractéristiques biochimiques et microbiologiques des vinaigres utilisés par les acteurs de  l’alimentation de rue dans la ville de Bobo-Dioulasso au Burkina Faso. La méthodologie a consisté à administrer un questionnaire à 180  vendeurs de salades, de poulets flambés, de poissons braisés, de viande de petits ruminants grillée, de viande de bœuf grillée et de  viande de porc au four. Puis, les vinaigres de l’ensemble des marques identifiées au cours de l’enquête ainsi que ceux de sept marques  de vinaigres importés ont été échantillonnés pour la détermination des paramètres microbiologiques et physico-chimiques. Les résultats  indiquent que 100% des acteurs enquêtés utilisent des succédanés de vinaigres de fabrication locale en lieu et place des vinaigres de fermentation. Ces acteurs méconnaissent la différence entre succédanés de vinaigre et vinaigre de fermentation. Certaines étiquettes ne  mentionnent pas la teneur en acidité tandis que 87,71% des étiquettes affichent des valeurs incorrectes. La flore aérobie mésophile totale  ainsi que les levures et moisissures ont été dénombrées sur 14,29% des succédanés de vinaigres.

Published: September 2024

En Côte d’Ivoire, la culture de l’oignon (Allium cepa) est pratiquée principalement au nord du pays pendant la saison sèche pour des  raisons climatiques et d’adaptation variétale. La production nationale ne couvre que 5% des besoins de la population, ce qui oblige le  pays à importer le reste de sa consommation. Cette étude avait pour objectif de contribuer à l’amélioration de la production de l’oignon  en Côte d’Ivoire par l’identification de variétés performantes, adaptées pour la production pluviale ou estivale au centre du pays. Pour ce  faire, trois variétés d’oignon dont Violet de Galmi, Ares et Syngenta 8362 ont été expérimentées en saison sèche et pluvieuse au centre du  pays sur deux années consécutives. Au cours des essais, les paramètres agronomiques ont été évalués et les analyses  phytochimiques ont été réalisées. En saison sèche, les données collectées et analysées ont mis en évidence une bonne performance et  adaptabilité des variétés testées. En saison des pluies, l’étude a mis en évidence une meilleure performance et d’adaptabilité de la variété  Ares (22 t/ha). L’analyse phytochimique des variétés testées a révélé de forte teneur de polyphénols totaux et de flavonoïdes  totaux chez la variété Ares par rapport aux autres variétés, ce qui expliquerait sa résilience aux conditions de culture pluviale. Les  conditions pédoclimatiques du centre de la Côte d’Ivoire sont donc favorables à la culture de l’oignon aussi bien en saison sèche qu’en  saison des pluies. Les trois variétés testées peuvent être cultivées en saison sèche. Cependant, en saison pluvieuse, seule la variété Ares  est recommandée.

Published: September 2024

The objectives of present study were to prepare a bioadsorbent from Mannihot esculanta Crantz peels (MEB) and to examine its effectiveness in the removal of methylene blue (MB) dye from aqueous solution by adsorption process. The adsorption was studied in a discontinuous reactor. Effects of the following parameters were studied: dose of bioadsorbent, contact time, initial concentration and pH  of MB solution. The residual concentrations of MB solution were analyzed by UV-Vis spectrophotometry. The results obtained showed  that the bioadsorbent MEB has a specific surface area of 265.27 m2 g -1 and a maximum observed adsorption capacity (Qmo) of 94.12 mg  g-1 . The percentage of adsorption increased with the dose of biosorbent and the time due to the availability of free sites. The  adsorption was better in a basic medium, because of electrostatic interactions between negatively charged MEB surface and organic ions  of MB. The dose of 800 g of bioadsorbent and a pH solution of 10 were the optimal conditions of adsorption. Pseudo-first-order model  was more suitable for describing the adsorption of MB on MEB, compared with pseudo-second-order model. The Langmuir model was best for describing the adsorption of MB on MEB bioadsorbent compared to the Freundlich model. The Langmuir separation parameter  RL and Freundlich parameter 1/n, less than 1, indicate that the adsorption of MB on MEB was favorable. The bioadsorbent MEB offers a  high potential for adsorption of dyes in aqueous solutions.

Les karités améliorent la fertilité des terres cultivées. Cependant, n’est-il pas possible d'améliorer le parc à karité afin de maintenir la  fertilité des sols ? Une étude sur l’évaluation de l’influence des parcs à karité sur les propriétés chimiques des sols a été conduite dans la  région du Centre Sud du Burkina Faso en 2021 et 2022. Le dispositif expérimental était une parcelle paysanne subdivisée en trois (03)  blocs correspondant aux différents traitements à savoir : T0 : bloc jachère utilisée comme témoin ; T1 : bloc contenant des pieds de karité  sans régénération naturelle assistée (RNA) et T2 : bloc contenant des pieds de karité avec RNA. L’expérimentation a été conduite dans 3  villages chez trois (03) producteurs. Soixante-trois (63) échantillons de sols ont été prélevés dans les blocs. Les résultats ont montré que  la présence des pieds de karité augmentait le taux de carbone du sol de 17% sous parc à karité avec RNA et de 28% dans le parc à karité  sans RNA par rapport au sol témoin. La teneur en Potassium assimilable du sol augmentait également dans les parcs à karité sans RNA  (58%) et avec RNA (48%). Le fort taux de carbone, potassium et phosphore indiquent que les parcs à karité pourraient contribuer à  l'amélioration des propriétés chimiques du sol.
Directing eco-theatricality on the Nigerian stage: lessons from Ahmadu Bello University Studio Theatre
Authors: Liman Rasheedah
Published: September 2024

The intersection between theatre and environmental concerns dates back to the origins of theatre itself. Years of continuous intersection and interaction between the two have given rise to a dynamic field known as ecological theatre or what may be referred to as eco-theatricality. Extant episteme in the area recognizes the potential of theatre to contribute to environmental consciousness to harnessing the transformative power of the stage to engage audiences, evoke emotional responses, and promote environmental awareness. In the continent for example, place, space, things, objects and people are named and known according to the nature of relationship between them and the environment. Within this context, the environment is reified and apprehended as a concrete material rather than a mere object. It is nurtured and, in many cases, worshipped in ways that result in diverse mimetic arts, poetics and aesthetics. In this paper, I draw from select stage productions from the Ahmadu Bello University Studio Theatre and seek to inspire theatre practitioners, educators, and policymakers to consider alternative ways of making theatre that puts the environment at the forefront of production. The researcher considered two eco-friendly play productions; the production of Ahmed Yerima’s Mojagbe and Don Pedro Obaseki’s Azagidi: When gods Die. The choice of these two productions lies in the deliberate attempts of the directors to use reusable materials to create a green theatre mis en scene. The researcher also wants to emphasize that eco-directing is possible even when working with canonical play-texts that do not directly address issues of the environment. The theory of Eco-Theatricality is used as a conceptual bastion to understand the rupture that has taken place in man’s exploitation of the environment and the dramatist’s conscious efforts at providing solutions to the problems posed by climate change.
Combating climate change through development communication: the Agricola multipurpose experience
Authors: Iroh Emmanuel , Aghamelu Helen
Published: September 2024

The need to educate farmers through the use of development communication (DC) techniques in ensuring food security necessitated this study. Climate change affects farmers who depend on natural rain-fed farming and agriculture. During such change, crops, seedlings, stored food, farming implements as well as storage facilities/infrastructures are damaged, leading to food insecurity. The work is hinged on the t Technology Determinism Theory (TDT) attributed to the American sociologist, Thorstein Veblen, which insists that technology, technological development, communications technology and media are pivotal to any social change in society. This is because, changes in society is propelled by the advent of new technology, development of innovation leading to a new order. The primary data for the study was obtained through the use of Development Communication technique of disseminating vital information to Agricola Multipurpose  Farmers’ Cooperative Society through the social media. Focused Group Discussion of social media messages was used for the data analysis. The study concludes that proper information dissemination to farmers will in no small measure assist in the management of climate change leading to food security. The study recommends the use of the new media for the dissemination of information to not only farmers but to the general public for the sustenance of agriculture and food security.
Design properties and costumes as identifiers of cultural diversification among the Bura and Tiv people in climate change
Authors: Fanyam Joel Avaungwa
Published: September 2024

Climate change in Nigeria has created a substantial human population movement and expanding design concepts due to ecological effects. It has necessitated constant research on ways of solving human needs in order to survive. One of those needs is a cultural practice that has been diversified by industrial production, occasioning loss of some natural materials, to build properties and costumes that can meet a large population demand. Using the direct observation, interview, historical-analytic and investigative approaches, this article posits that given the circumstances of climate change, there are elements of cultural diversification between the Bura and Tiv people that can be identified using performance properties and costumes. The conclusion is that climate change has increased creativity, accessibility, saved time, energy, and cost of consumption as well as increased durability of stage design materials among the studied ethnicities.
Youths and social vices: a critical evaluation of drug addiction in Sweet-Sweet Codeine
Authors: Aniukwu Nkemakonam
Published: September 2024

The campaign against drug addiction has taken different dimensions in various countries of the world. Nigeria seems to be battling with different shades of social vices that are ravaging its most promising talents, the youths. This study looks at the relationship and ripple effects of social vices and thus, evaluates BBC documentary film, Sweet-Sweet Codeine (2018). Moored in Social Responsibility Media Theory (SRMT), the study uses descriptive and content analysis modalities of qualitative research to evaluate drug addiction among the youths in Nigeria. The article examines how the ‘Say No to Illicit Drug’ campaign can best be supported and the need for activists, campaigners and government to take responsibility and create robust documentary films, jingles and messages that are geared towards educating the populace about the devastating activities that could lead to drug abuse, trafficking and addiction, so that children and young adults can internalise and grow with the message. The study suggests that the youths’ attention could be diverted from drug abuse and addiction by interrogating the dangers of the social vice in more documentary films that would discourage their involvement in such inacceptable act. The energy of the young people could be channelled positively to champion this drive, advocating against drug addiction, drug abuse and, drug trafficking that affect not only their health, productive energy but the environment generally. The researcher, therefore, recommends that the government should utilise the opportunity offered by documentary films to push the campaign against social vices, including drug addiction.
Impact of climate change on agricultural festivals in Igboland: the case of I Wa Ji
Authors: Okeke Tochukwu J.
Published: September 2024

In traditional Igbo society, a bountiful harvest begets an exciting festival which is used tocelebrate nature’s benevolence on the people and the appeasement of the respective gods and goddesses perceived to have aided the fruitfulness of the crops. Hence, agricultural festivals are determined and celebrated based mostly on that season or time of the year when the weather is most clement and the farmers are at rest in preparation for the next planting season. This study uses historical-analytic and direct observation methods to interrogate how climate and weather conditions affect agricultural festivals. It further seeks to understand the reasons why particular festivals are celebrated at specific periods of the year using the I wa Ji festival of the Umudioka people as a paradigm. It finds that agricultural festivals are set and celebrated at seasons when the weather is most accommodating and perhaps productive. It further observes that climatic and weather conditions influence communal wellbeing and that the effect of a clement or adverse weather condition impacts heavily on the verve, and otherwise, of the community. This in turn, affects the nature of the festival and its attendant performances.

The model street method: considering its suitability beyond poverty and sustainability into post-conflict settings
Authors: Grierson Shelley , Maistruk Paul
Published: September 2024

Introduction: The model street method was developed in 2015 to provide a framework for delivering high-impact, low-cost, scalable  community health interventions for communities affected by poverty in Africa. Since then, the method has been adapted to other  contexts, including sustainable redevelopment of urban areas in Europe and North America. Therefore, the suitability of the model as a  template from which other contexts could benefit should be considered. Post-conflict settings have several features in common with  poverty settings, where this model has been well demonstrated as effective.
Method: The method involves physically transforming a community through improved neighbourhood infrastructure and design. The  aim is to improve the physical and psychological wellbeing of the residents. In its flagship project, residents of the deprived  neighbourhood Dandora (Kenya) achieved a significantly improved quality of life. The project was delivered over six stages across 18  months. These stages included field research, collaboration laboratories, community workshops, building parties, implementation, and launch.
Results: Key success measures included improvements in perceived safety and security of residents, and better livelihood  opportunities, relationships with authorities, play opportunities for children, and drainage and environmental quality. The results  achieved recognition in several international awards. The method has since been applied to other neighbourhoods in comparable settings, such as Cape Town, Accra, and Kampala. It has also been adapted successfully to settings other than poverty alleviation,  including its use in Europe and North America.
Conclusion: As a community health intervention method, it is low-cost, and its focus on  collaboration maximises suitability across a variety of contexts. However, there are unique features specific to post-conflict settings, so it  is recommended that the model street methods’ suitability for application in postconflict settings be further considered and investigated.

Pronunciation has regained its existence in the investigative attempts in the areas of TESOL, Sociolinguistics, and Intercultural Communication. This burgeoning growth has proven the importance of pronunciation teaching and learning, notable in this technology-based language learning era. However, little attention has been given to the description of how the participant learned English pronunciation through internet-based video lessons (IBVL). Hence, this study addressed the void. Avril (a senior high school student in Tasikmalaya, West Java, Indonesia) was recruited as the investigative participant. The data were collected through semi-structured interviews and analyzed with Thematic Analysis. The findings reported that she learned English pronunciation by imitating the English tutor of the MmmEnglish channel. She learned by applying three main stages, namely listening and reading, listening and repeating, and shadowing.

The path to be an educator can be filled with difficulties, particularly for pre-service teachers enrolled in programs such as Asistensi Mengajar. The Asistensi Mengajar program, as a first step toward a teaching career, is critical in preparing undergraduate students from the Faculty of Teaching and Training for the demands and rigors of the educational landscape. This journey, however, is not without its challenges. Additionally, comprehensive studies investigating the challenges encountered by EFL pre-service teachers during the program are limited, considering the relatively new modifications implemented within the segment of the curriculum. These changes reflect broader trends in teacher education, which place a greater emphasis on practical experience, mentorship, and classroom management skills development. The result shows that there are four major area of the problems: 1) writing lesson plan 2) classroom management 3) preparedness and anxiety 4) positive working relationship with mentor teachers and peers. These challenges developed since they did not have much experience and teaching time as they were beginners. The results highlight the need for continual support, mentorship, and training to address these challenges and better prepare for the demands of the teaching profession. Additionally, to guarantee the comprehensive development of teaching abilities and competencies, a more comprehensive provisioning phase is required. Educational institutions and stakeholders should work to establish a supportive learning environment that fosters the growth and development of future educators.

A key component of learning a language is listening, which is necessary for the growth of receptive and productive language skills. Extensive Listening (EL), which involves engaging with a wide range of audio materials in the target language, has emerged as a significant pedagogical tool for enhancing listening skills. This study investigates the effectiveness of EL in improving language proficiency through a 13-week program involving three undergraduate students in an English language course. Utilizing a qualitative research design, the study explores students' perceptions of the benefits, challenges, and overall impact of EL on their English language skills. The findings indicate that students perceive EL as beneficial for vocabulary acquisition, pronunciation, and listening comprehension. However, challenges such as difficulties in finding relevant content and understanding diverse accents were also identified. The study provides valuable insights into optimizing EL programs, emphasizing the need for curated content and structured syllabi to better support learners. These results contribute to the existing literature on EL by highlighting its role in language learning and offering practical recommendations for educators to enhance instructional practices. The study underscores the importance of fostering an effective learning environment tailored to the needs and preferences of language learners. Future research is suggested to see the influence of various listening materials, the effectiveness of certain techniques, and to examine the long-term impact of EL across a broader learner demographic to further validate its effectiveness as a language acquisition tool.

Discourse is a concept that allows different explanations based on different approaches that examine all dimensions of the messages hidden in the codes in a text. There are processes or processes related to all language practices that turn into action in discourse. Discourse analysis, on the other hand, is a way of thinking to create a perspective on social life and events, which consists of conceptual elements. It is possible to benefit from more than one discipline in discourse analysis. In this study, discourse analysis of Durbilmez's poem called ‘The Earth Trembled With Cries’ which she shared on social media, was made in the context of the language-emotion-thought trilogy of Kahramanmaraş-centered earthquakes. By examining the macro and micro structures of the text in question, its semantic diversity has been revealed. The psycho social situation, individual and social traces of the two major earthquakes were evaluated within the framework of discourse analysis. Reality experienced with rhetorical analysis has been examined in many ways by considering both the semantic, syntax, pragmatic structure and the socio-cultural context outside the language analysis in the text. Thus, the content, grammatical, structural, interactional and presentation features of the discourse examined were determined. Key words: Kahramanmaraş, earthquake, discourse, discourse analysis
ON THE ORİGİN OF THE VERB YAKTUR- “TO GET BOOKS, COPİES ETC. PUBLİSHED” İN OLD UYGHUR TURKİSH
Authors: ÇALIŞ BESLİ Kerime
Published: September 2024

There are many words witnessed in the historical Turkish dialects or only in the Old Uyghur Turkish. One of them is the verb yaktur- arose to reproduce works to spread Buddhism. The word is not found in texts with Runic letters. The reason for this may be due to the fact that paper and printing techniques are not used in the writing of these texts. In the explanations given by the researchers, the origin of yaḳtur- is not entirely clear. This verb is mostly seen in Old Uyghur Turkish with the meaning 'to get books, copies etc. printed or to print'. The word in question is not found in texts with Runic letters. This may be due to the fact that paper and printing techniques are not used in Runic letter texts. We think that yaktur- 'to get books, magazines, etc. printed’ can be combined with the verbs *ya- and yak- in terms of root, meaning and structure. For this reason, the relationship between the meanings "to print books, copies etc." with the verbs *ya- "to approach", yak- to "approach", yak- to "drive, to rub" have been examined and explanations have been made in terms of etymology, structure and semantics. Key words: Old Turkish, Old Uyghur Turkish, Tantric Buddhism, yaktur-, to print books, journals etc.
