Authors: Kiburi Sarah Kanana , Paruk Saeeda , Chiliza Bonginkosi 
Published: July 2024

Digital interventions have been used for psychosocial treatment in substance use disorder but there is limited research on their application in Kenya. Determining the acceptability and attitude towards use of digital intervention in substance use disorder psychosocial treatment is important. The aim of this study was to assess the acceptability and attitude of healthcare providers towards use of digital interventions for psychosocial treatment at a methadone clinic in Kenya. A descriptive cross-sectional survey was carried out among healthcare providers. A structured self-administered questionnaire was used to collect data on sociodemographic variables and acceptability and attitude towards use of digital interventions in substance use disorder treatment. Technology acceptance model (TAM) was used as conceptual basis for this study. Data was analyzed using SPSS whereby a descriptive analysis was conducted and Pearson’s coefficient used to assess the relationship between the TAM constructs. The data is summarized in tables, figures and a graph. Twenty-one health care providers participated comprising 76.2% females and mean age of 33 (SD 6.9) years, of which 66.7% had training in addiction and 23.8% had ever used digital intervention previously. Acceptability was high with 90.5% agreeing that psychosocial treatment can be provided through digital interventions, 80.9% reported digital intervention would improve access to treatment and 76.2% viewed a digital intervention as cost effective. Majority (76.2%) agreed that digital intervention can influence substance use and patients would benefit from the intervention. Using the technology acceptance model, perceived ease of use was associated with perceived usefulness and attitude toward using; and perceived usefulness was associated with attitude towards use. These findings show a high acceptability and positive attitude towards use of digital interventions in substance use disorder treatment among the health care providers at a methadone clinic. This can inform design and implementation of digital interventions among individuals with substance use disorders in Kenya to improve patient outcome.

Published: July 2024

In response to the growing concern about climate change, the study focuses on rainfall, a complex and challenging meteorological variable to predict compared to temperature. This research introduces an innovative approach to model rainfall data, leveraging probability distributions from the exponential family. The study utilizes secondary data encompassing monthly rainfall measurements in millimeters (mm) spanning from 1986 to 2020, obtained from the Nigeria Meteorological Agency (NiMET) – covering a span of thirty-five years. To identify the most suitable distribution, various model efficiency criteria, including log-likelihood, Kolmogorov-Smirnov test, Cramer-Von Mises, Anderson Darling, and Akaike Information Criterion (AIC), are employed. The analysis highlights the Weibull distribution as the most fitting model, exhibiting the highest likelihood value, along with the lowest values for the Kolmogorov-Smirnov test, Cramer-Von Mises, Anderson Darling, and AIC. For six States under consideration: Abuja, Lagos, Edo, Kebbi, Taraba, and Enugu, the study establishes the Weibull distribution as the superior choice. Notable log-likelihood and AIC values for each location reinforce its suitability for modeling rainfall data in Nigeria. Specifically, the log-likelihood and AIC values for Abuja are 1910.155 and 3824.309, respectively, and similar trends are observed across the other locations. Consequently, the study strongly recommends the adoption of the Weibull distribution as the preferred model for rainfall data modeling in Nigeria. Additionally, it encourages further research into rainfall data modeling employing the Weibull distribution within the context of time series models, both with and without seasonality, utilizing the well-established Box-Jenkins methodology

Groundwater remains the largest source of potable water in Damaturu town. The study of gross radioactivity and its associated hazard risks in potable water is crucial to the health and well-being of the populace of the study area. Thus, radiological hazard indices such as annual effective dose, excess lifetime cancer risk, lifetime hereditary effect, and lifetime fatality cancer risk due to gross alpha and beta radiation from fifteen samples of borehole water have been evaluated. The mean values obtained from the analyses are 2531.48E–5 mSvy–1 & 5637.92E–5 for AED, 12.18E–5 & 23.26E–5 for ELCR, 443.01E–5 & 845.69E–5 for LHE and 12.18E–5 & 23.26E–5 for LFCR, respectively. By comparison, all the mean values obtained from this study are below the recommended limits set by UNSCEAR. Thus, the study indicates that the groundwater in the study area is radiologically safe for drinking purposes as the radiation dose level is very low. However, it is recommended that the study be further expanded to include all sources of potable water in the study area. This study aimed to provide baseline radiological survey of potable water for the study area.

Published: July 2024

Biogas technology is a way of tackling the increase in the production of organic wastes and rural energy problems in many developing countries like Nigeria. This study investigated the effect of granulated plantain peels on the biogas yield from cattle dung. The volume of gas produced was measured on a 5- day basis, and the pretreated substrate produced 46,151.6 cm3 against 17,224.7 cm3 from the untreated sample. Results showed a 168% increase in biogas produced when cattle dung was pretreated. The flammability test showed that production started on the first day after retention for the substrate pretreated and that an appreciable amount of methane content was produced only on the third to fourth day. In contrast, in the control, production started on the third day, and appreciable methane was observed on the fourth to fifth day. The compression test showed that biogas could be compressed with minimal changes in temperature as the temperature observed amounted to only a 0.19 ℃ rise per bar increase in pressure. The biogas compression experiment gave an accumulated mass of 214 g at 6.34 bar compared to 1000 g at 6 bar for standard LPG refilling. It is recommended that the produced biogas be purified before commencing compression in future works.

Published: July 2024

The condition of a fish pond's physiochemical parameters determines whether it is artificial or natural. One of the most significant tropical and subtropical freshwater fish is the tilapia (Oreochromis niloticus L.), which can eat both tiny zooplankton and phytoplankton. The purpose of this investigation was to determine the phytoplankton species found in the stomach and gut of tilapia (Oreochromis niloticus L.). Based on the physical traits of the phytoplankton species, fishpond waters, fish guts, and fish stomachs were identified using established procedures. The conventional techniques were employed to measure the physicochemical characteristics. Cyanophyceae and Chlorophyceae made up the majority of the phytoplankton that was discovered in the stomach, gut, and pond waters. Anabaena and Microcystis, two potentially poisonous cyanophyta species, were the most significant and prevalent phytoplankton species discovered in the intestines of tilapia. The study area's fish pond water had physicochemical parameter values of 26.3 o/oo for salinity, 7.1 for pH, 6.3 mg/L for dissolved oxygen, and 27.4°C for temperature. The study's findings may be applied to the biomanipulation of bothersome phytoplankton blooms in pond environments. The variation in the gut and stomach phytoplanktons of Tilapia fish was thus shown by the current preliminary investigation, which may be helpful in the creation of probiotics, medications, and industrial enzyme production. The pond under study was steady and appropriate for fish farming, with the goal of reintroducing fish to areas with a deficiency of fish populations.

Published: July 2024

This study investigates the impact of urban runoff on heavy metal concentrations in Ikpoba River, focusing on water, sediment, and fish gonads. Two sampling stations, upstream and downstream, were selected to assess variations in contamination levels. The concentrations of heavy metals (Cr, Co, Cd, Ni, Pb) in these samples were analyzed using an Atomic Absorption Spectrophotometer. Histopathological examinations of fish gonad tissues were also conducted. Downstream water samples in August exhibited significantly elevated lead (Pb) levels (0.037 mg/L) and cobalt (Co) concentrations (0.02 mg/L) compared to upstream levels. Sediment analysis revealed marked downstream contamination, with higher lead (Pb) levels (5.208 mg/kg) and cobalt (Co) concentrations (2.067 mg/kg) in August. Gonadal tissue analysis showed alarming contamination levels, with pelagic fish species displaying higher lead (Pb) and cobalt (Co) concentrations compared to benthic fish. These results highlight the vulnerability of pelagic species to heavy metal accumulation and indicate substantial pollution from industrial sources in the Ikpoba River. Urgent pollution control measures and ongoing monitoring are essential to safeguard the river's ecosystem and community health. Further research is recommended to explore the long-term consequences and potential health risks associated with heavy metal contaminants in the river.

Published: July 2024

The maximum mass of white dwarf stars, the final products of stellar evolution, is a crucial parameter in astrophysics. The Chandrasekhar limit, approximately 1.4 M⊙, is widely recognized as the upper limit. However, recent observations have revealed the existence of super-Chandrasekhar white dwarfs, which are believed to be precursors of bright type Ia supernovae. The origin and fundamental nature of these super-Chandrasekhar white dwarfs remain poorly understood, leading to extensive debate within the scientific community. This research paper reviews current understanding of the maximum mass limit of white dwarf stars, examining various models, including strong magnetic fields, rapid rotation, non-commutative geometry and modified theories of gravity. Furthermore, the criticisms and challenges encountered by these Models, such as electron captures, pycnonuclear reactions, general relativity, and observational limitations were analyzed. This analysis yielded a conclusion with the proposition of potential avenues for future exploration in this area of study.
