Research ArticleOpen accessIn the abstractCOVID-19 in the Era of Artificial Intelligence: Existing Technologies and A Strategic Model for Mitigating Future PandemicsBandar Mzel AlshammariPandemics have existed since the existence of life and will continue as life continues. Throughout many of the previous pandemics, what played a major role in decreasing their severity is how we mitigated and controlled them. The main reason for this is the time it takes for treatments and vaccinations to be developed, which usually takes a long time. Therefore, … …Journal of Computer Science, Vol. 20, Issue 5 · 20 Feb 2024 · 5,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbe-based Semi-permanent Soil Humidity SensorSoobin Jeon, Dongmahn SeoThe modern agricultural environment has the problems of an aging rural population and a decreasing rural labor population. Recently, smart farms based on information and communication technology have been studied to address environmental issues in agriculture. The smart farm consists of three parts: a data collection unit, a processing unit, and a control unit. Among them, the data collection unit … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 1,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Response Surface Methodology for Optimization of Nickel Adsorption in an Aqueous Solution by ClayNesrine Turki, Nesrine Boujelben, Zaineb Bakari, Jalel BouzidIn this study, Scanning Electron Microscopy (SEM), X-ray diffraction and BET surface area (SBET) methods were employed to characterize the adsorbent. Response Surface Methodology (RSM) was consider as a good method to assess Ni adsorption treatment and Box-Behnken design was used to examine simultaneous the effects of different experimental variables (pH, adsorbent dosage, contact time). Experimental results showed high adsorption … …American Journal of Environmental Sciences, Vol. 17, Issue 5 · 24 Nov 2021 · 6,292 accessesView PDFCite
Case ReportOpen accessIn the abstractCOVID-19 Diagnosis in Asymptomatic: RT-qPCR or any other Cost-Effective Method?Mayank Agarwal, Yogesh Arvind Bahurupi, Prasan Kumar PandaOn January 30th, 2020, the World Health Organization announced the COVID-19 outbreak as a Public Health Emergency of International Concern. In the view of this pandemic, early diagnosis is the mainstay for halting the disease progression. Quantitative real-time Reverse Transcriptase-Polymerase Chain Reaction (RT-qPCR) has been established as the cornerstone for the diagnosis of COVID-19. However, the significance of RT-qPCR positivity … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 2 Jun 2021 · 6,557 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge.
