Theoretical foundations of agile methodologies draw on several key theoretical frameworks complexity theory, complex systems, like digital banking ecosystems, exhibit emergent properties. Traditional linear approaches struggle to predict these. Agile embraces iterative development cycles and adaptability to changing requirements, acknowledging this complexity lean thinking, derived from manufacturing, lean thinking prioritizes eliminating waste and maximizing customer value. Agile translates this by focusing on short development sprints, prioritizing features with the highest customer impact, and minimizing unnecessary functionalities customer co-creation, traditional models often distance customers from the development process. Agile emphasizes customer co-creation, actively involving them in design and testing. This fosters a deeper understanding of customer needs and leads to more relevant and satisfying digital banking experiences. Agile practices in digital banking. Agile methodologies encompass diverse practices. This visual management system focuses on workflow optimization. Promoting a continuous flow of work from development to deployment user stories and acceptance criteria, User Acceptance criteria define the specific conditions a feature must meet for user approval. These practices ensure features align with customer needs and expectations. Agile methodologies hold significant promise for enhancing customer satisfaction in digit banking. Agile development allows banks to deliver new features and functionalities faster, keeping pace with evolving customer demands. Customers benefit from quicker access to innovative solutions that address their financial needs. This results in digital banking experiences that are intuitive, efficient, and cater to specific user needs. Increased Innovation, The iterative nature of agile fosters continuous learning and experimentation. Banks can test new features, gather customer feedback, and rapidly iterate upon them, leading to a more innovative and dynamic digital banking experience. Improved transparency and trust, agile practices promote open communication and collaboration between development teams and customers. Customers are kept informed of updates and have a voice in shaping the development process, fostering trust and a sense of ownership.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"52 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140363073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current intellectual property landscape presents challenges that demand strategic adjustments to strike a balance between incentivizing innovation and ensuring widespread accessibility to groundbreaking mental health technologies. Proposed recommendations encompass among others; advocating for shorter and more flexible patent terms, introducing legislative clarity on patent infringement, and promoting collaboration through legal measures. Additionally, the recommendations prioritize incentivizing information sharing, discouraging knowledge fragmentation, and embedding provisions that prioritize the accessibility and affordability of mental health technologies. This comprehensive strategy aims to create a legal environment that not only safeguards intellectual property but also propels the mental health technology sector toward heightened innovation, collaboration, and accessibility. The urgency for these reforms is underscored by the identified challenges within the intellectual property framework, emphasizing the need for nuanced adjustments.

Collection of seeds from diseased-free agro-ecological zones for reforestation programs in Ghana is key. To contribute to knowledge, a research was conducted to assess the effect of provenance on seed-borne mycoflora prevalence, germination and initial seedling disease incidence of Khaya Senegalensis seeds in three agro-ecological zones of Ghana. Four seed-borne fungi in three genera namely Aspergillus niger, A. flavus, Colletotrichum sp. and Penicillium sp. were isolated from Khaya Senegalensis seeds collected from the three different provenances namely Deciduous forest, Transitional and Guinea Savannah zones. Total seed-borne mycoflora infections on Khaya Senegalensis varied significantly (p<0.05) between provenances. Transitional and Deciduous zones recorded equal highest incidence of 100.0% total seed-borne mycoflora infections whilst seeds from the Guinea Savannah zone recorded the least total seed-borne mycoflora infection of 58.3%. Significant differences (p<0.05) were observed between provenances with respect to seed germination. Seeds from Guinea Savannah zone recorded the highest (73.7%) whilst the least percentage (16.3%) germination was observed in seeds sourced from the Deciduous forest zone. There were no significant difference (p<0.05) for percent seedling disease incidence amongst provenances. However, the highest (20.0 %) seedling disease incidence was recorded in seeds sourced from Transitional zone whilst the least (12.5%) recorded in seeds from the Deciduous Forest zone. Provenance has significant effect on seed-borne mycoflora prevalence and seed germination. It is recommended that seeds be collected from provenances with low incidence of seed-borne mycoflora to enhance high seed germination for reforestation programs.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"179 1‐2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140418015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, Bayesian approach for approximation of variances in measurement noise with KALMAN filter is applied for estimation of the dynamical state and measurement data in discrete dynamical system. Detection of uncertainty and estimation of those can be done simultaneously with adaptive KALMAN filter. This algorithm at each step time estimates noise variance and state of system with KALMAN filter. Then, approximation is formed at each step separately and at each step sufficient statistics of the state and noise variances are computed with a fixed-point iteration of a KALMAN filter. For showing influence of variance in measurement data on algorithm different simulations is applied. First, effect of variance and its distribution on detection performance is simulated in KALMAN filter without Bayesian formulation. Then simulation is applied to KALMAN filter with ability of variance tracking of measurement data.in these simulations, influence of distribution of measurement data in each step is estimated and true variance of data is obtained by algorithm and is compared in different scenarios. Afterwards, one typical modeling of nonlinear state space model with inducing noise measurement is simulated by this approach. Finally, the performance and the important limitations of this algorithm in these simulations are explained.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"1 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140418343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Malaria remains a major public health challenge especially in Sub-Saharan Africa, a major cause of mortality and morbidity, especially in children and pregnant women. WHO recommends Artemisinin-based combination therapies as the first-line drugs for the treatment of uncomplicated malaria but the emergence and spread of Artemisinin-resistance associated with mutations in K13 gene poses a threat to ACT efficacy. Detection of mutant K13 gene may provide the information on changes in parasite susceptibility to Artemisinin. This study was aimed at detecting K13 gene polymorphisms among human population in Nasarawa-West Senatorial District, Nigeria. A total of 385 blood samples were collected from selected hospitals and screened for malaria by microscopy (the gold standard). Species specific screening of the P. falciparum was done using RDT. Dried blood spots made from RDT positive samples were investigated for the presence of K13 genes by nested PCR. Sequencing detected mutant K13 gene. Results: 103 samples were positive for Plasmodium falciparum by RDT, PCR confirmed 48 K13 genes with a band size of 848 bp. Nucleotide sequence alignment revealed six Single Nucleotides Polymorphisms. The nucleotide sequences were converted to protein sequences and results showed a point mutation in 1(5.0%) of the 20 Pfkelch 13 gene sequenced. Conclusively, the need for continuous surveillance following the detection of mutant gene in the study population is recommended in order to have a wider picture of the parasite diversity for effective malaria control.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"8 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140420042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heat-cured acrylic resin is a common base material for dentures in dentistry. When exposed to acids frequently, the acrylic plate's surface becomes rough. Because of their health advantages, turmeric tamarind herb is commonly taken. Turmeric rhizomes and tamarind fruit are used to make herbal turmeric tamarind. The citric acid in tamarind fruit reduces the surface tension of acrylic resin that has undergone heat curing, increasing porosity and roughness. Materials and Method: 24 heat-cured acrylic resin plates that were pretested and divided into two groups of packed and unpackaged tamarind turmeric herbs were used in the laboratory experiment. The pH value of each group was measured. Each group's 12 samples were soaked for 1, 3, 5, or 7 days before the roughness was gauged and examined. Result: An analysis of the data using the two-way ANOVA test revealed a significant difference between the length of the immersion and the surface roughness of the heat-cured acrylic resin of 0.023 (0.005). However, the difference between the packaged and unpackaged turmeric tamarind groups was just 0.131 (> 0.005). Conclusion: The harshness of the heat-cured acrylic resin was altered by the soaked time in the tamarind turmeric herb. The development of roughness can be affected by some factors, including the presence of acids, especially citric acid, liquid absorption, pH, the breaking down of polymer bonds, the level of hydrogen ions, and improper packing methods.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"199 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140419078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within these atoms, the fundamental particles of electrons, protons, and neutrons engage in perpetual vibrational motion, thus engendering a surrounding energy field known as the \"Aura\". In the case of animate beings, the Aura serves as an indicator of their overall well-being, and there exists a positive correlation between the Aura and the state of health. It is postulated that the human Aura extends approximately 4 to 5 feet in proximity to the corporeal form. Inanimate entities, on the other hand, also emit a certain degree of energy within their vicinity, albeit in a lesser quantitative measure compared to the human Aura. The inherent qualities of inanimate objects are intrinsically linked to their respective Aura. Consequently, we have embarked upon a comprehensive investigation aimed at augmenting the Aura in both animate and inanimate entities. As part of this quest, an assortment of consumables, including edibles, alcohol, cigarettes, and electronic devices were systematically employed and scrutinized for their influence on the human Aura. Remarkably, it was observed that the handling of said inanimate entities led to a discernible diminution in the human Aura. Subsequently, inanimate entities were subjected to irradiation with mid-infrared waves measuring between 2 and 6 µm. Intriguingly, this intervention resulted in a notable amplification of both human and inanimate Auras. It is noteworthy to mention that our ongoing endeavors involve the utilization of a recently designed atomizer, designated as the Mid-Infrared Generating Atomizer (MIRGA), which generated 2-6 µm mid-infrared, and played a pivotal role in the aforementioned study.","PeriodicalId":499957,"journal":{"name":"Open access research journal of science and technology","volume":"410 1‐3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140417179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
