From the adoption of automatic printing to the transition to digital e-books, and the transformation of plays into movies, television, animation, and interactive games, Shakespearean works have consistently evolved to meet changing consumer preferences. This study aims to provide insights for creating effective product marketing strategies using generative Artificial Intelligence, drawing lessons from the enduring popularity and adaptability of Shakespeare's works
A Socio-Cultural Analysis of Users’ Intentions to Use Facemasks in the Post Covid-19 Era in Nigeria
Get PDFThis paper investigates individuals’ intention to use facemasks in the post-COVID-19 era using the extended unified theory of acceptance and use of technology. The intention to use the facemask during the COVID-19 pandemic was more compelling through enforcement rather than the individual’s will. In the post-COVID-19 era, the effects of facilitating condition, social influence, price value, performance expectancy, effort expectancy, hedonic motivation, experience and habit on the intention to use the facemask were investigated using the regressions analyses. A total of 417 respondents took part in the selection from government organisations, including higher institutions and public offices in South-West Nigeria and the Federal Capital Territory (Abuja). The result shows that facilitating conditions and hedonic motivation positively influenced the intention to use the facemask, while price value, experience and habit have negative impacts. Findings from this study suggest that facemask manufacturers and distributors must suitably define their products and strategies to suit the value perception of the user and beliefs that trigger social status and hedonic motivations in conjunction with the primary health benefits of the facemasks
Project Planning and Implementation in Public TVET Institutions in Nairobi County, Kenya
Get PDFThis study aimed to determine the influence project planning has on implementation of projects in public TVET institutions in Nairobi County, Kenya, due to limited empirical evidence on the phenomenon. Hoshin's model of strategic planning made up the study’s theoretical framework. The study adopted an explanatory research design and was conducted in public TVET institutions in Nairobi County. The target population of 132 respondents for the study constituted Ministry of Education officials and top management and staff members of public TVET institutions who were selected using a multistage sampling approach. The sample size was 79 respondents while 72 respondents returned questionnaires. Data was collected using semi-structured questionnaires and analyzed using descriptive (measures of central tendency, measures of frequency, and measures of dispersion) and inferential statistics (correlation analysis and regression analysis). The study found that project planning (p=.000) has significant positive effect on project implementation. Therefore, this research concluded that planning is a significant predictor of project implementation success in public TVET institutions in Nairobi County. The study urges future research to explore other types of project management practices and how they influence project implementation
Evaluation of Free Cooling Technique at the Telecom Cell Site in Ghana
Get PDFAir Conditioning (AC) is the primary source of cooling in a typical Cell Site (CS) although it consumes a large quantity of electricity. Excessive energy consumption due to air conditioning increases the operational expenses of telecommunication companies. Therefore, network operators have attempted various techniques to reduce the exorbitant cost of a cell site’s high-power consumption. A Free Cooling (FC) System is one such approach. This paper uses computer modeling to investigate how the FC System will function at a CS in Ghana for 12 hours (from 6 pm to 6 am). A shelter with dimensions of 3 m × 2.47 m × 2.45 m (L × B × H) is used in the study, with three window positioning scenarios (different window heights), namely: (a) an inlet window 0.5 m high, and the outlet window 1.5 m high, (b) an inlet window and outlet window both 1.0 m high and (c) an inlet window 1.5 m high, and the outlet window 0.5 m high. The analysis revealed that the shelter with inlet and outlet windows at the same height has the most efficient heat dissipation potential. Furthermore, at a set temperature threshold of 25 °C, the annual percentage share for the two operating modes is approximately 67% for AC and 33% for FC in 2020, 76% for AC and 24% for FC in 2021, and 61% for AC and 39% for FC in 2022. However, when the set temperature threshold is increased from 25 °C to 30 °C, the annual percentage share is approximately 0.01% for AC and 99.9% for FC in 2020, 0% for AC and 100% for FC in 2021, and 1% for AC and 99% for FC in 2022. Thus, the proportion of free cooling increases as the set temperature threshold is raised, indicating potential energy savings. It could be concluded that in Ghana, installing a cell site with an FC system and setting the temperature of its control system to 30 °C or higher will result in significant energy savings
Aptitudes des principaux porte-greffes de Mangifera indica L. à supporter les variétés primeurs comme Kent, Papaye et Ateudj en Casamance au Sénégal
Get PDFLa valeur de la production de mangue au Sénégal est estimée à près de 4 milliards de FCA. Toutefois, comme les autres filières fruits et légumes, la performance de celle de la mangue reste toujours en deçà des attentes. Afin de relever ce défi, cette étude porte sur le greffage des variétés locales pour améliorer leur productivité. Le présent travail réalisé dans le centre d’application du département d’agroforesterie qui se trouve à Ziguinchor, concerne le test de greffage de trois variétés de Mangifera indica L. précoces (Papaye, Ateudj et Kent) avec quatre porte-greffes (Papaye, Sierre Léone, Diourou et Kouloubadaséky). L’expérience a duré 18 mois (Juillet 2022 à janvier 2024). Ce travail a contribué à l’identification des meilleurs porte-greffes pour les variétés Papaye, Kent et Ateudj. Il est ressorti de cette expérience que la variété Kouloubadaséky donne un meilleur taux de réussite (93,33% ±11,55) avec la variété Ateudj. La variété Diourou donne le plus grand taux de réussite (90% ±10) avec la variété Kent. La variété Papaye a donné le meilleur taux de réussite (100%) avec elle-même. Les performances des variétés Kouloubadaséky, Diourou et Papaye sont révélées pour les greffons des variétés Ateudj, Kent et de Papaye. En effet les greffons ont donné des taux de survie élevés 80,88% pour Ateudj, 79,10% pour Kent et 76,19% pour Papaye. En termes de croissance le porte greffe Sierra Léone donne les meilleurs taux de croissance (greffon Ateudj [67,26% ±4,77] et greffon Kent [52,95% ±11,44]). Par contre le greffon Papaye croit plus s’il est supporté par le porte-greffe Diourou avec un taux de croissance de 71,71% ±8,25.
The value of mango production in Senegal is estimated at nearly 4 billion francs. However, like other fruit and vegetable sectors, the performance of the mango sector remains below expectations. In order to meet this challenge, this study focuses on the grafting of local varieties to improve their productivity. The present work, carried out at the Agroforestry Department's application center in Ziguinchor, concerns the grafting test of three early Mangifera indica L. varieties (Papaye, Ateudj and Kent) with four rootstocks (Papaye, Sierre Léone, Diourou and Kouloubadaséky). The experiment lasted 18 months (July 2022 to January 2024). This work contributed to the identification of the best rootstocks for the Papaye, Kent and Ateudj varieties. This experiment showed that the Kouloubadaséky variety gives a better success rate (93.33% ±11.55) with the Ateudj variety. The Diourou variety gave the highest success rate (90% ±10) with the Kent variety. The Papaye variety gave the best success rate (100%) with itself. The performances of the Kouloubadaséky, Diourou and Papaye varieties are revealed for the grafts of the Ateudj, Kent and Papaye varieties. Grafting yielded high survival rates: 80.88% for Ateudj, 79.10% for Kent and 76.19% for Papaye. In terms of growth, the Sierra Leone graft holder gave the best growth rates (Ateudj graft [67.26% ±4.77] and Kent graft [52.95% ±11.44]). Papaya, on the other hand, grows best when supported by Diourou rootstock, with a growth rate of 71.71% ±8.25
Savoirs locaux sur les pratiques culturales du caféier robusta et représentations des communautés locales sur le café en Province de la Tshopo (République Démocratique du Congo)
Get PDFLa non-utilisation des savoirs locaux peut affecter l'acceptabilité sociale des programmes. Cette étude évalue l'utilisation des savoirs locaux dans la caféiculture pour l'acceptation sociale des programmes d’atténuation des changements climatiques et la conservation de la biodiversité. Cent-huit caféiculteurs de robusta ont été enquêtés dans les sept territoires de la province de la Tshopo. La collecte des données s’est intéressée autant à la connaissance des pratiques culturales de caféier qu’à la représentation de caféier et/ou de café dans le quotidien des caféiculteurs. Les observations directes ont été associées à une interview, sous forme de récit de vie semi-structurée dans une application KoBoCollect via un Android. Les résultats ont montré que certaines techniques de la caféiculture consistent à diminuer la déforestation et ses impacts sur l’environnement. Le caféier est une source de revenus et une boisson stimulante par ses grains. La décoction de ses feuilles est utilisée en médecine traditionnelle. L’agroforesterie est conçue comme une stratégie de la résilience grâce à la diversification des services écosystémiques liée à l’agriculture et à la forêt.
The non-use of local knowledge may affect the social acceptability of programs. This study assesses the use of local knowledge in coffee farming for the social acceptance of climate change mitigation programs and biodiversity conservation.. One hundred and eight Robusta coffee farmers were interviewed in the seven territories of Tshopo Province. Data collection focused on knowledge of coffee growing practices as well as the representation of coffee and/or coffee trees in farmers' daily lives. Direct observation was combined with an interview in the form of a semi-structured life story in a KoBoCollect application via Android. The results showed that certain coffee-growing techniques can reduce deforestation and its impact on the environment. They contribute to the biological and natural regulation of the agroecosystem. The coffee tree is a source of income and a stimulating drink thanks to its beans. The decoction of its leaves is used in traditional medicine. Agroforestry is conceived as a resilience strategy thanks to the diversification of ecosystem services linked to agriculture
Lavendula Angustifolia, Rosmarinus Officinalis, Thymus Serpyllum and Origanum rotundifolium: Exploring natural solutions for inflammation and blood sugar management
Get PDFThe Lamiaceae family, including common herbs like rosemary and mint, is being investigated for its potential health benefits. In addition to numerous health benefits, research is looking into these plants' anti-inflammatory qualities and potential impacts on blood sugar regulation. More specifically, the Greek endemic Lamiaceae plants are proven to be of great importance, regarding their bioactive compounds and the antioxidant, antidiabetic, and anti-inflammatory properties they have. Researchers are interested in understanding how Lamiaceae plant compounds might work in the body. Besides, Antioxidants have an increasingly important function in reducing tissue damage and cytotoxicity caused by hydrogen peroxide and oxygen radicals in a variety of human disorders. This knowledge could lead to the development of natural approaches for managing inflammation and potentially even diabetes. These plant-based options may offer a milder alternative to some conventional medications. By supporting the body's natural regulatory systems, Lamiaceae plants could contribute to a more holistic approach to well-being. This study's objective was to review the literature on the anti-inflammatory, antidiabetic, and antioxidant properties of the Lamiaceae species Lavendula Angustifolia, Rosmarinus Officinalis, Thymus Serpyllum, and Origanum rotundifoliu
Bias correction of CORDEX-Africa regional climate model simulations for trend analysis in northeastern Lake Chad: Comparison of three bias correction methods
Get PDFIn order to better adapt to the consequences of climate change, regional climate models (RCMs) have been set up for simulations. However, these simulations are often subject to biases, making it difficult to use them directly in studies of the impact of climate change. It is therefore necessary to use bias correction methods to reduce discrepancies between observed data and the data simulated by RCMs. The aim of this study is to analyse the results of three bias correction techniques (scaling, EQM and GQM) applied to rainfall data and mean minimum and maximum temperatures from CORDEX-Africa Regional Climate Models (RCMs), specifically in the north-eastern region of Lake Chad. Various statistical measures such as Pbiais, RMSE, R2 and EAM were used to assess the performance of each bias correction method in this study. In addition, the adjusted Mann-Kendall test and the Sen slope estimator were used to examine trends and their magnitude over the recent (1975-2004) and future (2021-2050) periods with a significance level of 5%. Overall, based on the statistical measures evaluating the effectiveness of the bias correction techniques, this study shows that all the methods tested were able to reduce the biases of the RCM outputs satisfactorily. In particular, the linear scaling approach proved to be more effective in correcting biases than the EQM and GQM methods. Therefore, an analysis of future trends in mean annual precipitation and temperature (minimum and maximum) was carried out for the RCP4.5 and RCP8.5 scenarios using the linear scaling method to correct for data biases. An increase in precipitation and temperature was observed in the study area over the recent period. The results of multi-model averaging of regional climate change for the RCP4.5 and RCP8.5 scenarios indicate a significant increase in mean annual temperatures (minimum and maximum) in the future. As far as annual precipitation is concerned, only an increase is forecast under the RCP4.5 scenarios. Under the RCP8.5 scenarios, a trend towards stable precipitation is predominant, with the exception of the south of the zone, where an increase has been observed. In the light of these results, it is clear that the impact of climate change will intensify in the region studied in the future

Get PDFSe realizó la propuesta de nuevos valores para el efecto multitrayectoria, relación señal-ruido, saltos de ciclo e integridad a través de estadística descriptiva con la finalidad de realizar el control de calidad de la Red Geodésica Nacional Activa en México para la constelación GPS. El análisis fue llevado a cabo mediante el software TEQC considerando los valores propuestos por el IGS, RVM y mediante la implementación de estadística descriptiva. Se analizaron las observaciones GPS de 32 estaciones de monitoreo continuo en el periodo 2020 al 2023. Los resultados demuestran que para el efecto multitrayectoria en la L1, 17 estaciones cumplen con el criterio, en el caso contrario para la L2 donde 27 estaciones superan el valor recomendado. Para la relación señal-ruido, solo dos estaciones presentan una potencia baja en ambas frecuencias. En relación con la integridad, solo 5 estaciones no cumplen con el valor propuesto, por su parte, para los saltos de ciclo, solo 5 estaciones no cumplen con el valor recomendado. Finalmente, se demuestra que las estaciones que pertenecen a la Red Geodésica Nacional Activa cumplen con los valores recomendados, por lo que es posible utilizar las estaciones para monitoreo de la corteza terrestre y trabajos topógrafo-geodésicos conforme a la nueva actualización masiva de equipos y receptores derivado de los valores presentados.
Descriptive statistics were used to propose new values for quality control of Mexico's Active National Geodetic Network, specifically for the multipath effect, signal-to-noise ratio, cycle slips, and integrity of the GPS constellation. The analysis was carried out using the TEQC software considering the values proposed by the IGS, RVM and by implementing descriptive statistics. Based on the results, the proposed criteria are met by 17 stations for the multipath effect in L1, while for L2, the recommended value is exceeded by 27 stations. For the signal-to-noise ratio, only two stations have low power on both frequencies. Regarding integrity, only 5 stations do not comply with the proposed value. Meanwhile, for cycle slips, only 5 stations do not comply with the recommended value. Finally, it is demonstrated that the stations that belong to the Active National Geodetic Network can be used for monitoring the Earth's crust and topographic-geodetic work in accordance with the new massive update of equipment and receivers derived from the values presented
