Modelling Spatial Variation, Distribution, and Prediction of Fluoride Levels in Groundwater in the Njoro River Catchment, Kenya

George Morara Ontumbi,Mercy Jepkirui
Fluoride, whose levels are higher than the World Health Organization (WHO) recommended level of 1.5 mg/l, results in health issues. Therefore, fluoride contamination is a matter that calls for concern by all people and governments, especially in countries where volcanicity has been experienced. This study sought to model spatial variation, distribution, and prediction of fluoride levels in groundwater in the river Njoro catchment. This study aimed to observe the levels of fluoride and give recom...

Flow-Solid-Thermal-Chemical Coupling Model for In-Situ Extraction of Oil Shale Using High-Temperature Supercritical CO

Mohammad Zakir Zamani,Fahadurahman Samadi,Azharulhaq Kamran,Zaedar Khan,Shakeel Hussain
In situ oil shale development using supercritical CO2 is a promising method due to CO2’s low viscosity, high heat, and mass transfer efficiency. This technique allows CO2 to penetrate micro pores, improve heating efficiency, promote kerogen decomposition, and act as an extractant for crude oil, enhancing oil and gas recovery while being environmentally friendly. Findings indicate that CO2 injection results in higher oil yield, while water inje...

Analysis of the Culicid Fauna (Diptera: Culicidae) in the Swamps of the Town of Souk el Arbaa, Morocco

Abdelouahed Kbibch,Khalid El Khokh,Khadija El Kharrim,Driss Belghyti
The order Diptera and the suborder Nematocera include blood-sucking insects known as Culicidae. They are prominent either because they act as vectors for pathogenic organisms of certain species or due to the nuisance they cause. To better understand the habitat of these mosquitoes in the Souk El Arbaa region (north of Rabat), monitoring of certain physico-chemical parameters was conducted from February 2012 to September 2013. This was aimed at providing information on the optimal conditions for ...

Exploratory Analysis of Algeria Meteorological Drought Using SPI and SPEI

Imen Choutri,Awad Hussien
Drought frequency has increased worldwide in recent years due to global warming, causing famine, water shortage, and economic loss. This paper aimed to assess the meteorological drought in Algeria, using two globally accepted drought indices, Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI). The SPI and SPEI at 3-, 6-, 9-, and 12-month timescale were obtained to analyze the temporal variability of different drought levels. Pearson correlation ...

Religion Is Not History

Mohammad HekmatAfshar
Starting with an intrareligious comparison between Islam and Christianity, this paper tries to discuss transreligiously. Expounding the difference between religion and Faith, I have tried to put forth a new theory set under “The Divine Brush”, to articulate God’s tradition, constantly being consistent with its earthly time, arriving to mankind through Faith; the Faith which is redefined as being other than religion, alike to the title, which religion is also not that of history. Moreover, the co...

Cybersecurity Framework for Kenyan Universities in Conformity with ISO/IEC 27001:2022 Standard

Patrick Macharia Gichubi,Bernard Maake,Ruth Chweya
The rapid adoption of enterprise resource planning (ERP), the necessity for remote access to information systems, and the swift development of digital technologies like IoT and cloud computing have increased cyberattacks on organizations, including universities. Despite not being as heavily targeted as major industries, universities have become more vulnerable due to open ERP systems, insufficient cybersecurity investment, and limited cyber expertise. This study aimed to enhance cybersecurity in...

Research on Open Access Journals Based on Article Processing Charges

Meiping Wang
Authors pay article processing charges for open access journals, while readers can access articles. With the development of open access, the expenditures of article processing charges are increasing. It becomes a burden for scientists, especially in developing countries. Since it is a market competition, most publishers must charge article processing charges. However, the price of article processing charges should be reasonable. This study chooses 494 journals to analyze article processing charg...
