This study aimed to ascertain the prevalence of asymptomatic malaria among primary school pupils in Dala Local Government Area, Kano State, Nigeria. Utilizing a crosssectional design, blood samples were collected from 107 pupils through finger prick. These samples were then subjected to microscopic examination following the preparation of both thin and thick blood films. The overall prevalence of asymptomatic malaria was found to be 21.5%, with 23 pupils testing positive for the parasite. Gender-wise, male participants exhibited a higher infection rate (73.9%) compared to their female counterparts (26.08%). Age-specific analysis revealed that the 13-16 years age group had the highest prevalence of asymptomatic malaria at 73.9%, whereas the 5-8 years age group had the lowest at 2.38%. These results highlighted the substantial presence of asymptomatic malaria among school-aged children, particularly within the 13-16 years age bracket. The study underscores the need for targeted public health interventions to identify and treat asymptomatic malaria infections in order to mitigate the silent transmission within this vulnerable population.

The R3BP is still an exciting and active research field that has been getting attention of scientists and astronomers because of its applications in dynamics of the solar and stellar systems, lunar theory, and artificial satellites. The equations of motion are usually the starting point in the investigations of the dynamical predictions of the infinitesimal mass. Therefore, in this paper, we examine the derivations of the dynamical equations of the R3BP with Poynting-Robertson (P-R) Drag force and variable masses. In this model formulation, both primaries are assumed to vary their masses under the combined Mestschersky law (CML) and they move in the frame of the GyldenMestschersky equation (GME). Further, the bigger primary is assumed to be emitting radiation force, which is a component of the radiation pressure and the P-R drag. The non- autonomous dynamical equations of the model are derived and converted into the autonomized equations with constant coefficients using the Mestschersky transformation (MT), the CML, the particular solutions of the GMP, and a transformation for the time dependent velocity of light. We observed that the P-R drag of the bigger primary depends on the mass parameter, radiation pressure, velocity of light and the mass variation constant . The derived systems of equations with variable and constant coefficients can be used to model the long-term motion of satellites and planets in binary systems.

In Nigeria, demographic and population data play a crucial role in shaping these plans. This research investigates the impact of demographic structure on the country's economy, with a specific focus on key characteristics such as population size, birth rate, mortality rate, growth rate, GDP growth rate, and fertility rate. The study analyzes demographic features alongside GDP growth rate data spanning from 2003 to 2022. The findings reveal a robust correlation between birth rates and GDP growth, indicating that population dynamics significantly influence economic development. Additionally, positive relationships are identified between death rates and GDP growth, underscoring the impact of mortality issues on economic outcomes. The regression model demonstrates that demographic factors collectively mold Nigeria's economic growth trajectory, shedding light on the intricate dynamics between demography and economic development. Through time series analysis, the model exhibits low errors and high explanatory power. However, residual analysis highlights serial association, emphasizing the temporal demographic effects on economic growth. Ultimately, the study underscores the potential contributions of demographic characteristics to Nigeria's economy. Policymakers and economists keen on leveraging demographic shifts for economic advancement will find valuable insights in this research. As demographic considerations increasingly play a pivotal role in Nigeria's economic growth, strategic planning and decision-making must take these factors into account.","PeriodicalId":479620,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":"5 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140658836","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 green synthesis of MgO NPs is cost-effective and environmentally friendly. Characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier- transform infrared spectroscopy (FTIR) confirmed the successful synthesis of nanoparticles with unique properties. Debye-Scherrer equation is used for the determination of particle size, which was found to be 15.7nm. The potential application of MgO NPs in the removal of cadmium (Cd) contaminant from water sources was investigated through batch adsorption experiments. Cadmium pollution poses a severe threat to ecosystems and human health due to its toxic nature and persistence in the environment. MgO NPs, with their high surface area and reactivity, efficiently adsorbed and immobilize cadmium ions from water. Adsorption isotherm models indicated that Langmuir isotherm is the best model to describe the adsorption of Cd2+ on magnesium oxide nanoparticles prepared by elephant grass extracts. It was found that a removal of greater percent of Cd2+ could be accomplished through adsorption with 0.05g of magnesium oxide nanoparticles, an initial concentration of metal at 5ppm pH of 10 and at contact time of 65minutes.

Human judgment was employed in evaluating the system based on orthography accuracy. Results show that the developed translator is 95 percent accurate while experimental subject respondents have an accuracy of 58 percent. The developed machine translator’s performance is closer to the Experts’ but higher than that of the experimental subject respondents, this shows that indigenous people are not good at writing Okun language and find it hard to separate the dialect from Yoruba language. Hence, research in EnglishOkun machine translation should be intensified in order to prevent the language from going into extinction and future research should consider extending the full form bilingual lexicon of Okun language to achieve improved accuracy.

This study focused on assessing the cytotoxic effects of heavy metals recovered from dumpsites on the meristematic tissue of root tips of Allium cepa L. Soil samples, collected from central dumpsites containing heavy metals, underwent standard procedures. The concentrations of heavy metals in the samples were determined using the Association Official Analytical Chemist (AOAC) method. Each sample was digested with acids, neutralized with Calcium Oxide (CaO), and used to grow Allium cepa at varying concentrations, determining the LD50 of each sample. The LD50 concentrations were then employed to investigate cytotoxic effects on Allium cepa using standard techniques. Processed soil samples yielded Pb, Cr, Cd, Ni, Co, Zn, Fe, and Cu at different concentrations, many of which exceeded the WHO standard values.

It is the oldest formation and the main reservoir unit in the entire Benue Trough. Porosity loss is an essential component of petroleum reservoirs that needs to be properly investigated for the purpose of hydrocarbon exploitation. Compaction and cementation processes are partly responsible for porosity loss in many known reservoirs around the world. Outcropping units of the formation around Lakwaime and Dogon Dutsi in Yola Sub-basin have been subjected to an integrated approach involving field observations, petrographic analysis and porosity measurements in order to understand the contribution of each of the processes. Modal composition of the samples shows that they are mostly lithic arkose to feldspathic litharenite, with quartz as the most common detrital mineral grain. Grain fracturing has been attributed to mechanical compaction, whereas grain contacts like sutured and concavo-convex are products of chemical compaction. The average values of compactional-porosity loss (COPL), cementational-porosity loss (CEPL), and compaction index (ICOMPACT) in the studied samples stand at 19.51%, 4.18% and 0.82 respectively. The study indicates that the role of compaction in porosity loss is greater than that of cementation as shown by the COPL-CEPL diagram and, as such considered to be generally responsible for the porosity loss in Bima Sandstone.
