This article examines five popular sorting algorithms: bubble sort, selection sort, insertion sort, merge sort and quicksort through analysis of time complexity and space complexity. The major goal is to determine the most efficient algorithm with respect to given data sizes and conditions that are typical with computational resources available in Nigeria. It has been found out that when datasets are small, insertion sort and selection sort perform well while for larger datasets one should consider using Merge Sort or Quick Sort because they have lower time complexity O(n log n). In addition, it looks at how these algorithms manage data integrity especially in areas like financial transactions (payments) and educational data management in Nigeria. Tests were performed using integer and string datasets to investigate the practical consequences of applying these sorting algorithms in real-world Nigerian applications. The outcomes show that having an appropriate sorting technique can greatly improve the performance as well as resource utilization across many sectors thus making it one of the ways through which a country can become greater.</p> K.

Comprehensive assessment checklist based on WHO and UNICEF standards was used to evaluate the availability and adequacy of water facilities. Water samples were collected from 13 public secondary schools using a stratified and proportionate sampling techniques, ensuring representation across different water sources, including boreholes, pipe-borne water, and dug wells. The samples were then transported to the Sokoto State Water Board laboratory for microbial testing. The analysis specifically targeted the presence of indicator bacteria, including <em>Escherichia coli</em> (E. coli), total coliforms, and fecal streptococcus, to assess the microbial quality of the water sources. The findings revealed significant spatial disparities in the distribution of schools and highlighted areas with inadequate water facilities. Microbial analysis indicated varying levels of contamination across the different water sources, with dug wells having the highest E. coli count, averaging 11.33 CFU/100ml. The total average E. coli count across all water sources was 6.08 CFU/100ml, which exceeds the Nigerian Industrial Standard (NIS) Maximum Permissible Limit (MPL) of 0 CFU/100ml, indicating a concerning level of contamination. These results suggest a substantial risk to public health, particularly for students and staff relying on these water sources. The study emphasises the urgent need for interventions such as reconstruction and rehabilitation of water infrastructure and regular water quality testing to ensure safe drinking water is provided in public secondary schools in...</p> Nasiru Lawal, Aliyu Dadan-Garba, Bolanle Joel Ajibuah, Olumide Akinwumi Oluwole Copyright (c) 2024 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2637 Wed, 11 Sep 2024 12:31:58 +0000 ASSESSING THE IMPACT OF INFLATION, UNEMPLOYMENT ON POVERTY AND HUMAN DEVELOPMENT INDEX IN NIGERIA https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2518 <p>This study carefully assessed the impact of inflation and unemployment on poverty and the human development index in Nigeria using an annual dataset from 1991 to 2023. A vector autoregression (VAR) model was used for data analysis. The findings of the analysis indicate that the unit root test for the variables at first difference was stationary at the 5% critical value, the Johansen cointegration test for both trace and maximum eigenvalue had one cointegrating equation, meaning that there is a short- and long-term equilibrium relationship among the variables, while the optimal lag selection criteria showed a lag length of order one. Hence, these results met the requirements for using vector error correction (VEC) model estimation, given that the CUSUM test also indicates the model residual parameters' stability. Meanwhile, the impulse response functions revealed that a unit shock to inflation increases unemployment and poverty, as well as reduces government spending on human development through education and health. Also, the forecast variance decomposition showed the influence of the variability of inflation among variables, demonstrating its negative impact on various facets of the economy, leading to high rates of unemployment and poverty as it hampers human development. In view of this, the empirical study submits that researchers, policymakers, and development practitioners should design effective policies and programs that will help in reducing the effect of inflation and unemployment rates on poverty and the human development index through poverty reduction intervention programs aimed at fostering sustainable economic growth and human development in Nigeria.</p> Yakubu Musa, A.

Typical turbid water samples were collected from Opa River in Ile-Ife, Nigeria. The collected turbid water samples were subjected to treatment by the fabricated household water treatment system. Effects of selected operational factors on the performance of the system was evaluated and optimized using Taguchi technique. The optimum values of the factors were utilized for the full treatment of typical water samples using the system and similar system available commercially. The performance of the system was based on the ability to remove the pollutant from the turbidity water samples. Cost analysis was conducted for the fabricated household water treatment system and similar types that are commercially available. The study revealed that the performance of the system was between 98.8% and 100 % with an overall performance of 99.5 %. Time of settlement, pore Size of the filter, Concentration Coagulant and Turbidity of the Raw water had impact on the performance of HWTS. Significance of the factors were in-order of pore Size of the filter &gt; time &gt; Concentration Coagulant and &gt; Turbidity of the raw water. It was concluded that the performance of the HWTS was perfect compared with the commercially available filter. The HWTS is economically effective and sustainable (0.0575 US$ per day) compared to commercially available HWTS (0.0639 – 0.1187 US$ per day). There was no significant difference between the performance (individual and overall) of fabricated...</p> Mohammed D. Idi, Oluwaseun K. Akinmusere, Ayotunde Oluyemisi Akanni, Kehinde A.

This study assessed the heavy metal contamination in water around the industrial layout in Sagamu, Ogun State, Nigeria. Seven (7) water samples were collected and analyzed for their physicochemical and geochemical properties using inductively coupled plasma mass spectrometry (ICP-MS). Water facie was determined using a Piper plot. Geo-Accumulation Index (Igeo), Contamination factor (C<sub>f</sub>), Contamination degree (C<sub>d</sub>), Quantification of Contamination (QoC) and Hazard Index (HI) of the heavy metals in water samples were obtained. Results show the ranges of physicochemical properties as, pH (4.1 - 5.9), total dissolved solid (78 - 292 ppm), electrical conductivity (0.1 - 0.4 µS/cm) and temperature (30.1 - 32.2°C). The concentration of metals in groundwater samples were obtained as Cd (0.001 - 0.004ppm,), As (00007 - 0.0011ppm), Cr (0.005-.01ppm), Pb (0.0003- 0.046ppm), Zn (0.0204-0.26ppm), Fe (0.000005- 0.013ppm), Mn (0.0009-2.5ppm) and Ni (0.001-0.03ppm). Igeo for heavy metals &lt; 5, Fe has C<sub>f </sub>of F&gt;6 (strongly polluted) and C<sub>d</sub>&gt;32. Fe and Mn have positive QoC values indicating anthropogenic sources. Results show the HI to be greater than 1 indicating children and adults are at low risk of non-carcinogenic health problems. Water in the study area was contaminated with Pb and Mn thereby reducing its quality and exposure through derma and ingestion can cause adverse health effects. Proper sanitation with contamination control and monitoring strategies should be adopted to safeguard the health of water consumers from the study area.</p> Bamidele Ruth Faleye, O. M. Ajibade, O. E.

The study was conducted on 210 (6 blind) quarter milk samples from 108 goats. Cultural examination was used as the gold standard to compare the accuracy of the following diagnostic tests: CMT, Masttest, Mastidin, Kerba test, Milk test, WST, BBST and SCC. The incidence rates were highest with CMT (28,7%) and lowest with Mastidin (22.2%). Cultivation revealed the presence of Coagulase-positive <em>Staphylococcus</em>, Coagulase-negative <em>Staphylococcus</em>, <em>Streptococcus species</em>, <em>Bacillus species</em>, <em>Lactobacillus species, Escherichia coli, Salmonella species, Enterobacter species </em>and<em> Klebsiella species</em>. No growth was observed on Brucella Agar. The sensitivity, specificity and predictive value of various tests were recorded and it was found that CMT had the highest sensitivity (32.89%), specificity (96.55%) and predictive value (96.15%) than compare with the other diagnostic methods for diagnosis of sub clinical mastitis in goat. The accuracy of all the conducted diagnostic tests when compared cultural examination were considered to be statistically significant (p&lt;0.01). It can be concluded thatCMT can be used as a first screening tool for detecting suspected samples for further investigation for SCM also as the decision criteria to treat or to cull the animals in herds with high prevalence of SCM.</p> Faruq Ahmad Danmallam, Ansu Ceesay, Mujtaba Haruna, Yusuf Abubakar, Abdulganiyyu Ahmad Abdullahi, Shehu Yakubu Usman Copyright (c) 2024 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2682 Wed, 18 Sep 2024 08:46:25 +0000 FIELD OCCURRENCE AND COMPOSITIONAL CHARACTERISTICS OF THE CLAY HORIZON IN THE PATTI FORMATION, SOUTHERN BIDA BASIN NORTH-CENTRAL NIGERIA https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2696 Paul Ekele Ojoma, Onimisi A.

This paper introduces the Howusu Metric Tensor to extend the Schrödinger equation into spherical coordinates, accommodating gravitational fields that are regular and continuous with a reciprocal decrease at infinity. This leads to the derivation of the Riemannian Schrödinger equation, offering insights into quantum behavior in curved spacetime. Building on previous work integrating quantum mechanics with general relativity and Finsler geometry, our approach addresses the limitations in capturing gravitational subtleties. By incorporating the Howusu Metric Tensor, our model accounts for gravitational potential in spherical coordinates, providing a more precise description of quantum phenomena under gravity. The resulting Riemannian Schrödinger equation reveals new quantum behavior influenced by gravitational forces, opening new research possibilities in cosmology and astrophysics, where quantum-gravitational interactions are key. This study demonstrates the advantages of using the Howusu Metric Tensor over previous models, highlighting its potential to unify quantum mechanics with gravitational effects more coherently and comprehensively.</p> Vivian O.

Political economists and data analysts opined that fuel subsidy removal frees up resources, while others say it enhances poverty. This study was conducted to investigate the impact of fuel subsidy removal on consumer goods. The rentier state theory was employed as the theoretical framework for analysis, and the study used the descriptive survey method with a cross-sectional procedure as the research design. The study employed the frequency distribution, and simple percentages to analyze the impacts of fuel subsidy removal. The Wilcoxon signed-rank test was used to test the formulated hypotheses at a significance level of 5%. The study affirmed that the removal of fuel subsidy increased the cost of consumer goods, since factors such as house rent&nbsp; and transportation which generally have effect on the cost of goods are affected, leading to poor standard of living of Nigerians.</p> F.

This study compared the variability in albedo for two locations, Owerri and Ikeja distributed over Nigeria's coastline climatic regions, using monthly average daily observed meteorological data on global solar radiation alongside wind speed, mean temperature, surface pressure and relative humidity over thirty-nine-year period (1984-2022) from the National Aeronautics and Space Administration (NASA). 11 models in all, divided into three groups, were derived from regression models with two, three, and four variables were developed and tested using five validation indices of Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), t-test and coefficient of determination (R<sup>2)</sup>. All the developed models that stood out the most were ranked according to their suitability for estimating surface albedo. For Owerri, the three-variable regression model which relates wind speed, relative humidity and mean temperature, ALB7 (Eqn. 26g) performed best, while the two variable regression model which relates the relative humidity and mean temperature, ALB15 (Eqn. 27d) performed best for estimating surface albedo for Ikeja. The Earth’s emitted surface temperature for Owerri ranged from 219.1845 K in August to 239.6133 K in January, while for Ikeja it varies from 221.4955 K in August to 238.7534 K in November. The longwave radiation at both locations is in the infrared part of the electromagnetic spectrum, as indicated by the maximum emission wavelength values.</p> Timothy Afolabi Kola, D. O.

DELILE AND ANOGEISSUS LEIOCARPUS (DC.) GUILL. & PERR IN DIABETIC WOUND HEALING: EVIDENCE FROM MALE WISTER RAT https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2690 <p>The use of plants in traditional medicinal systems has been practiced for thousands of years and continues to supply people with new remedies. The current study evaluated the wound healing effect of ethanol extracts of <em>Acacia</em> <em>nilotica</em> pod and <em>Anogeissus leiocarpus </em>stem bark on rat models. Fourty two (42) Streptozotocin (60 mg/kg) induced diabetic male Wistar rats were divided into seven (7) groups of six (6) rats each. A one-centimeter-diameter excision wound was created on the mid-dorsal area of the experimental diabetic rats. The treatment groups were treated daily with the plant extracts by oral administration at doses of 200 mg/kg and 400 mg/kg for 14 days. Blood glucose level, percentage of wound contraction of the experimental rat groups were observed for 21 days. Histopathological examination was also carried out at the end of the experiment. The findings indicated that both <em>A. leiocarpus</em> at doses of 200 mg/kg, 400 mg/kg and <em>A. nilotica</em> at 200 mg/kg enhanced wound contraction in the diabetic rats at day 14 compared to the standard drug (Metformin) which occurred at day 21. This showed a significant reduction in blood glucose level of the treated diabetic rats as well as wound healing effect by the tested plants extract.</p> Sakina Sani Buhari, Bala Sidi Aliyu Copyright (c) 2024 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2690 Wed, 18 Sep 2024 15:40:09 +0000 SYNERGISTIC IMPACT OF RICE HUSK ASH AND PULVERIZED CLAY BRICK BLENDS ON CEMENT MORTAR DURABILITY IN MAGNESIUM SULPHATE ENVIRONMENTS https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/2705 Mukhtar Isma'il, A.

To solve this, it is imperative to provide probability models that accurately represent the behavior of certain real-world phenomena. having considered these problems, the study proposed a new lifetime distribution, the Modified Dhillon Distribution (MDD), developed using the Beta integrated model approach. The study examines the statistical properties of the new distribution such as the Quantile function, Moment, Moment generating function, Entropy, and reliability functions. Moreover, the maximum likelihood approach was used to estimate the distribution parameters. Using real data, the study demonstrates the applications of the MDD using two sets of real data sets, and it has the minimum value of AIC, BIC and CAIC. Therefore, based on the results the study concluded that the MDD offers the best fit out of all the competing distributions.</p> A. S. Iliyasu, O. O. Ishaq, A. O. Abduhamid, A. Ibrahim, S. S.

Hence, understanding its geotechnical properties is key to the determination of their industrial applications. The geotechnical characteristics of six residual clay samples from the crystalline basement rocks in Zariagi, Lokoja, north-central Nigeria, were evaluated to determine its suitability for construction and civil engineering. Parameters assessed included particle size distribution, consolidation, specific gravity, Atterberg limits, linear shrinkage, loss on ignition, compaction, and permeability. Grain size analysis and Atterberg limit tests classified the samples as clayey. Liquid limit ranged from 36% to 37%, indicating low plasticity. The plastic limit ranged from 33.38% to 34.66%, and the plasticity index from 2.14% to 2.71%, suggesting the clay exhibits low to medium swelling potential when wet and can withstand volumetric shrinkage when dry, meeting the requirements for barrier soils. Compaction tests revealed an optimum moisture content (OMC) of 14.90% to 18.50% and maximum dry density (MDD) of 1270 kg/m³ to 1320 kg/m³, indicating suitability for building construction. Linear shrinkage percentages ranged from 2.86% to 4.29%, indicating moderate linear and low volumetric shrinkage. Loss on ignition values from 3.74% to 4.49% suggested low organic matter content and the absence of swelling clays. Permeability values ranged from 0.000133 cm/sec to 0.000140 cm/sec, suggest moderate permeability. The results suggest the Zariagi clay is suitable for barrier soil and building construction applications.</p> Tope E. William, Tope S. Alege, A. Onimisi Jimoh, O.
