A review of rusle model

In this paper, we attempted to review the soil erosion studies conducted throughout the globe using Revised Universal Soil Loss Equation (RUSLE). We searched the SCI, Scopus, Web of Science, Google Scholar database and various theses for this study. Though RUSLE is the most widely used model for estimation of soil erosion, the factors, namely rainfall erosivity, soil erodibility, slope length and steepness, cover management and conservation practice; vary greatly over different climatic zones, soil properties, slope, land cover and crop phase, respectively. Depending upon those variations, researchers have developed various sets of equations for different factors of RUSLE. These equations can be useful to map soil loss for many places on this planet.

Phytoconstituents determination of cannabis sativa plant extracts

Background: Cannabis sativa has garnered significant attention due to its complex phytochemistry and diverse pharmacological properties. Given the rising interest in medicinal cannabis, understanding its physicochemical properties is crucial for drug development, quality control, and abuse prevention. This study aimed to analyze its phytoconstituents, with a focus on the isolation and profiling of cannabinoids. Methods: Fresh C. sativa leaves were macerated in ethanol to obtain a crude extract, which underwent phytochemical screening to detect alkaloids, flavonoids, cardiac glycosides, terpenes, steroids, and resins. Thin-layer chromatography (TLC) was performed using a n-hexane/diethyl ether (8:2) ratio as the mobile phase to separate cannabinoids, with visualization under UV light. Column chromatography further purified the extract, and subsequent TLC confirmed cannabinoid-rich fractions. Hydrogen peroxide-modified TLC was employed to assess oxidation effects on cannabinoid stability. Results: Phytochemical screening confirmed the presence of alkaloids, flavonoids, terpenes, and resins, while saponins and tannins were absent. TLC analysis revealed distinct Rf values for tetrahydrocannabinol (THC = 0.94) and cannabidiol (CBD = 0.90), with color differentiation indicating successful separation and a more polar nature of CBD. Column chromatography yielded enriched fractions, validated by TLC. Hydrogen peroxide exposure altered Rf values of 0.78 to 0.8, suggesting oxidative degradation. The study identified THC and CBD as dominant markers, alongside minor cannabinoids, reinforcing C. sativa’s complex chemical profile. These findings give clues to further research into standardized extraction protocols and stability testing to optimize medicinal applications of the plant and its phytoconstituents. Conclusions: This study highlights the efficacy of TLC and column chromatography for cannabinoid isolation and profiling. The presence of THC, CBD, and other bioactive compounds underscores C. sativa’s dual therapeutic and psychoactive potential.

Prevalence and associated factors of overweight and obesity among persons with type 2 diabetes in africa: a systematic review and meta-analysis

Background Type 2 diabetes and obesity are serious public health concerns globally and a growing burden in Africa. Both conditions have serious repercussions on health when they co-occur, yet the extent of their co-occurrence in Africa remains unknown. Therefore, this review aimed to identify the prevalence and associated factors of overweight and obesity among persons with type 2 diabetes in Africa. Method A systematic search was conducted on PubMed, MEDLINE, Embase, African Index Medicus (AIM), and African Journals Online (AJOL) for observational studies that reported the prevalence of overweight and/or obesity among type 2 diabetes patients in Africa. The prevalence data from individual studies were aggregated through a random-effects meta-analysis. The I2 statistic was used to evaluate between-studies heterogeneity, while subgroup analysis and mixed-effects meta-regression were performed to identify sources of heterogeneity. We assessed publication bias using funnel plots and Egger’s test. This review adhered to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Results Of 1753 records retrieved, 80 articles were eligible for this review, with 74 cross-sectional studies included in the meta-analysis. The pooled prevalence of overweight and obesity was 35.6% and 25.6% respectively, while the overall prevalence of both overweight and obesity was 61.4%. Also, the pooled prevalence of both overweight and obesity across the five geographical areas in Africa ranged from 56.9% in East Africa to 88.5% in Southern Africa. Nineteen factors were significantly associated with overweight and obesity among patients with type 2 diabetes. Conclusion The high prevalence of overweight and obesity among patients with type 2 diabetes is a significant public health concern that transcends geographical boundaries within Africa. The findings from this review highlight the need for innovative weight management interventions that are tailored to the cultural context of the African setting

Knowledge and attitudes towards stroke in semi-urban communities in north central nigeria

Stroke and its associated disabilities are a growing public health challenge in many developing countries where a combination of poor awareness and poor medical care is driving up mortality rates. The rising cases are attributed to the rising prevalence of uncontrolled hypertension, obesity, smoking, alcohol abuse, and diabetes mellitus within the population. The prevention of stroke through awareness, knowledge, and lifestyle modification is a common approach used in public health intervention programs. Awareness and knowledge of stroke vary widely between communities partly because of access to relevant health information. This study assessed awareness, knowledge of stroke risk factors, and attitude toward stroke prevention. This study was a community-based survey among adults ≥40 years old in semi-urban communities of two local government area councils of Benue State, North Central Nigeria. The sixteen-item questionnaire used in this study is subdivided into socio-demographic information, knowledge of risk factors, symptoms of stroke, current morbidity, and attitude toward stroke prevention. The survey was done using two adults per household selected using simple random method and completed questionnaires were retrieved for analysis. The Chi-square test was used to determine the association between demographic variables and knowledge of stroke. The result showed poor levels of stroke awareness (47.3%), knowledge (44.6%), symptoms (44.6%), risk factors (20.6%), and symptoms (44.6%). Awareness of stroke and its risk factors is significantly association with age, gender, marital status, educational status, occupation, and income. Many respondents had poor knowledge of stroke and its risk factors. There is a need for improvement in stroke awareness in underserved communities, particularly those with limited access to mass media.

An international, interlaboratory ring trial confirms the feasibility of an extraction-less “direct” rt-qpcr method for reliable detection of sars-cov-2 rna in clinical samples

Reverse transcription–quantitative polymerase chain reaction (RT-qPCR) is used worldwide to test and trace the spread of severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). “Extraction-less” or “direct” real time–reverse transcription polymerase chain reaction (RT-PCR) is a transparent and accessible qualitative method for SARS-CoV-2 detection from nasopharyngeal or oral pharyngeal samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental resources than full RT-qPCR. This study engaged 10 global testing sites, including laboratories currently experiencing testing limitations due to reagent or equipment shortages, in an international interlaboratory ring trial. Participating laboratories were provided a common protocol, common reagents, aliquots of identical pooled clinical samples, and purified nucleic acids and used their existing in-house equipment. We observed 100% concordance across laboratories in the correct identification of all positive and negative samples, with highly similar cycle threshold values. The test also performed well when applied to locally collected patient nasopharyngeal samples, provided the viral transport media did not contain charcoal or guanidine, both of which appeared to potently inhibit the RT-PCR reaction. Our results suggest that direct RT-PCR assay methods can be clearly translated across sites utilizing readily available equipment and expertise and are thus a feasible option for more efficient COVID-19 coronavirus disease testing as demanded by the continuing pandemic.

Media credibility, misinformation, and communication patterns during mco of covid-19 in malaysia

During Movement Control Order (MCO) of COVID-19, many information has been disseminated through both traditional and social media. Some of that information was credible and came from reliable sources while other information was fake and included misinformation, disinformation, and infodemic. The people needed credible information rather than fake one in this critical time. This study aimed to explore the credibility of media, information sources, the main issues, and preferred communication patterns and method of works perceived by Malaysians during MCO. A total of 300 questionnaires were distributed, and 210 were returned. The results of this study showed that the majority of respondents 69% relied on new media as their main source of information compared to 30.9% who relied on traditional media. However, a total of 64.8% of respondents considered traditional media as more credible and accurate compared to 35.2% for new media. Additionally, the main concerns and issues followed by respondents on media were health, economic, social, education and others. Finally, a total of 55.7% preferred face to face communication compared to 44.3% who preferred online communication. A total of 51% of respondents preferred to work from the workplace or office compared to 49% who preferred to work from home. Television played a significant role during the pandemic period due to its high credibility as perceived by Malaysians. The main intriguing implication of this study is considering the traditional media as more credible than social media by the Malaysians although the social media was their main source of information.

Enhancing hydro power plant efficiency through hybrid optimization approach

The inclusion of hydroelectric power is crucial to Nigeria's overall energy mix, playing a significant role in electricity generation. However, the Shiroro hydro plant, one of the main facilities located on the Kaduna River, is currently facing operational obstacles due to deteriorating infrastructure and inadequate maintenance practices. To overcome these challenges and improve efficiency within Nigeria's hydroelectric power sector, a hybrid-optimization approach has been proposed. This study sought to enhance the efficiency of the Shiroro hydro plant by implementing this innovative method. To achieve our objectives and address pertinent research questions, a mixed research method combining primary and secondary data was employed. The analysis included hydropower modeling and hydro-turbine input-output modeling. Three optimizer models, namely the particle swarm optimizer (PSO), Ant colony optimizer (ACO), and Artificial bee colony optimizer (ABCO), were utilized to formulate objective functions and task representations. The study involved comparing the daily output and fitness response of the Shiroro hydro plant through swarm optimizer iterations. The findings revealed a clear correlation between the turbine's power output and the water flow rate and water column height, suggesting that altering these factors could significantly improve the plant's performance. The comparison of the PSO, ACO, and ABCO models demonstrated that PSO and ABCO generated optimal or near-optimal solutions, while ACO produced suboptimal results. Consequently, the study concluded that enhancing the Shiroro hydro plant's output was feasible by increasing the water flow rate and column height. Additionally, the utilization of PSO and ABCO models proved to be an effective means of accurately predicting the turbine's output. As a result, the study recommended the integration of hybrid optimization techniques to monitor and identify any deviations in the Shiroro hydro plant's daily power output. This approach would enable prompt maintenance to be carried out, preventing significant damage to the plant. Ultimately, this research contributes valuable insights into improving the efficiency and performance of Nigeria's Shiroro hydro plant.
