Information on sociodemographic characteristics of the caregivers was assessed with the aid of a validated semi-structured questionnaire. Weight, oedema, and Mid up Arm Circumference (MAUC) of the children were measured weekly to monitor the progress of the programme. This study shows that 8(26.67%) of the caregivers were aged 21 – 25 years and 26 - 30 years each, while 7 (23.33%) were 18 - 20 years of age, only 1(3.33%) of the caregiver was above 40 years. The mean age of the respondents was 27 years. Educational status shows that 17(56.67%) of the caregivers attended Secondary school as the highest level of education, 5(16.67%) had no formal education while only 1 attended tertiary institution. Occupation wise, 36.67% (n=11) of the caregivers were Artisan/Skilled Worker, followed by 10(33.33%) who were housewives. The result of the MUAC of the SAM children for 8 weeks shows that the mean value for the first week was 9.73. The boosters of the programme show 76.7% of RUTF, 10% of porridge beans, tofu and turn brown. The<strong> c</strong>ost of transportation and distance as barriers was 60% and 26.7% respectively. The performance indicators show 77.8% cure rate, 8% default rate, 2.7% death rate and no recovery rate was 11.1%. &nbsp;Geographic coverage is 5.8% which when compared with the percentage standard is alarming. Therefore, geographic coverage in this study site was low and this would translate into low program effectiveness</p> Haruna Abdullahi, Sallau Abdullahi Balarabe, Owolabi Abraham O., U.

The study focused on the socioeconomic characteristics of the chilli pepper marketers, profitability and marketing efficiency of chilli pepper as well as constraints of chilli pepper marketing. The result of socioeconomic characteristics showed that majority of the chilli pepper marketers (96.2%) were male and 46.2% were between the ages of 30-39years, and the majority of the marketers had attended various level of education in the study area which means they can read and write. The results showed that 69.8% of the sampled marketers have less than 10 people in their household. The result further revealed that 49.1% of the marketer’s haves less 10 years’ experience in the marketing of chilli pepper in the study area. Chilli pepper marketing was profitable venture with a net margin of 2,520.74 per 30kg of bag. Marketing of chilli pepper was found to be efficient in view of the high marketing efficiency obtained. The result revealed that the constraints faced by chilli pepper marketers were lack of uniform measure, poor credit facilities, transportation, inadequate storage facilities and poor market infrastructures. It can be concluded that pineapple marketing was profitable and efficient in the study area despite the constraints faced by the marketers. And therefore can be recommended that Construction of good road network to reduce damage of pineapple during transportation and plastics trays should be provided</p> A. T. Lawal, A. Y. Gaya, A.

To determine the consistency of the accuracy of the method for the intended purpose, there is a need to apply it in some other parts of the country. As a result, this study presents the verification of the consistency of the proposed transformation of global geoid method accuracy for local geoid model of Nigeria determination. DGNSS observations were carried out to obtain the coordinates of the used points. The processed global geographic coordinates were used with online software (GeoidEval) to obtain the EGM 08 geoid heights of the points. The global geographic coordinates, the global geoid heights of the points and the transformation parameters from WGS 84 to Minna datum were applied to obtain the transformed (local) geoid heights of the points using a Microsoft Excel program. The transformed geoid heights were compared with their corresponding geoid heights from the gravimetric-geometric local geoid model of the study area to obtain the model RMSE (accuracy). The obtained accuracy (2.0172 m) was compared with those of the gravimetric-geometric geoid model of the study area (0.675 m) and the transformation of global geoid heights when the method was applied in part of Abuja (0.0014 m). The comparison results showed the inconsistency of the accuracy of the proposed method. It is recommended that the method should not be applied for the intended purpose.</p> O. F. Oduyebo, M. N.

The transformation geoid model was determined using the Kotsakis (2008) model for the transformation of global geoid heights to local geoidal undulations. To obtain its accuracy, the root mean square error (RMSE) index was applied. The computed accuracy is 2.0172 m. To apply the determined geoid model in the study area, as well as improving on the computed accuracy, the model was fitted to the gravimetric-geometric geoid model of the study area. The fitting result shows that geoid heights can be computed using the determined geoid model with an accuracy of 1.1041 m in the study area.</p> O. F. Oduyebo, M. N. Ono, S. O.

This study aimed at assessing the Toxic implications of Heavy Metals in Drinking Water Sources of Loko and Mararraba in Nasarawa using Micro Plasma Atomic Emission Spectroscopy (MP-AES). The results showed that, seven heavy metals along with their respective concentrations for both Loko and Mararraba in mg/L (Zn (0.19 and 0.23), Cd (0.00 and 0.00), Fe (0.05 and 0.04), Cu (0.01 and 0.01), Pd (0.01 and 0.01), Ni (0.003 and 0.002) and Mn (0.092 and 0.027)) respectively were present in the water samples. The Hazard Quotient (HQ) was all recorded to be lower than unity. The Hazard Index (HI) was also recorded to be 4.6x10<sup>-4</sup> and 5.7 x 10<sup>-4</sup> for both Loko and Mararraba respectively, value less than unity. This makes non-carcinogenic effects negligible. The total excess life cancer risk was found to be 36.1.4x10<sup>-13</sup> and 41.46x10<sup>-13</sup> for both Loko and Mararraba respectively, value less than that of U.S (1.0x10<sup>-4</sup> to 1.0x10<sup>-6</sup>) and South Africa (5.0x10<sup>-6</sup>). This makes carcinogenic effects negligible. Regular monitoring and evaluation of the water at the sample locations is recommended.</p> Usman Rilwan , A. A.

The foods include lima bean porridge, lima bean-benniseed and lima bean-hungry rice. These foods were subjected to proximate and amino acids analysis using standard procedures and analytical methods. Amino acid composition of lima bean-benniseed recorded higher content of essential amino acids leucine (6.97g/100g), lysine (7.10g/100g), methionine (2.60g/100g), threonine (3.81g/100g), and also had higher content of non-essential amino acids, tyrosine (3.45g/100g), alanine (4.54g/100g), serine (3.94g/100g), glutamic acid (12.94g/100g) and aspartic acid (8.68g/100g). Lima bean-hungry rice food had higher content of isoleucine (4.04g/100g), phenylalanine (4.13g/100g), tryptophan (1.26g/100g). Proximate composition shows that the protein content of lima bean-benniseed food (8.33%) and lima bean porridge (8.30%) were significantly (P&lt;0.05) higher than lima bean-hungry rice food while lima bean-benniseed food had higher content of crude fat (13.46%), ash (2.28%) and crude fibre (4.09%) compared to other foods. The carbohydrate content (24.58%) of lima bean porridge was significantly (P&lt;0.05) higher than other foods. The study shows that lima bean foods have a good nutritional profile therefore; increase in the consumption of foods prepared with lima beans could serve as an addition to food-based strategies used in decreasing malnutrition and its effects</p> Charity Dankat, Owolabi A Olumuyiwa Copyright (c) 2021 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/782 Mon, 17 Jan 2022 16:46:29 +0000 EVALUATION OF Bacillus thuringiensis FROM DIFFERENT HABITATS FOR LETHALITY AGAINST LARVAE OF SOME SPECIES OF MOSQUITO https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/783 <p>This work was aimed at evaluating the lethality effects of <em>Bacillus thuringiensis </em>isolated from different habitats<em> against </em>larvae of some species of mosquito. The isolated and identified microorganism &nbsp;from the different sampling sites were subjected to bioassay against different species of mosquito larvae at 0, 8.0 × 10<sup>9</sup>, 1.6 × 10<sup>10</sup>, 3.2 × 10<sup>10</sup>, 6.4 × 10<sup>10</sup>, and 7.2 × 10<sup>10 </sup>cells/ ml. The result of the study revealed that <em>B. thuringiensis </em>isolated from compost manure had the highest bioactivity of 100% mortality against all the three species of mosquito larvae used in this work at the concentration of 3.2 × 10<sup>10</sup> cells / ml while those isolated from garden soil, refuse, animal residue and dry leaf residue gave 100% mortality at 6.4 × 10<sup>9</sup> cells / ml against the three species of mosquito larvae with the exception of that isolated from animal residue which gave 95% mortality against aedes larvae at 6.4 × 10<sup>10</sup> cells/mls. Analysis of variance at P &lt; 0.05 revealed a significant difference in activity of <em>B. thuringiensis </em>isolated against mosquito larvae belonging to different species. This indicated that <em>Bacillus thuringiensis </em>had higher lethal activities against culex and anopheles larvae than aedes larva.</p> Maimuna Zubairu, Abdulaziz Zubairu, Karima M.

Six years (2015-2020) satellite data of Temperature, Pressure and Humidity both at the surface (12m) and at 100 m AGL, were used for the study. The data retrieved were used to determine the monthly, seasonal and annual surface radio refractivity values for the locations. Results show that the values of surface radio refractivity (Ns) in Abuja was slightly lower than Ilorin with average values of 335.62 and 351.07 N-Units obtained for the six years respectively. Average values of Ns, obtained during the dry season months in Abuja and Ilorin were 299.40 and 321.03(N-units) respectively while average values of 360.24 and 368.21 (N-units) were obtained during the wet season months in Abuja and Ilorin respectively. Higher values of Ns, were recorded generally during wet compared to the dry seasons’ months in all the years and study locations. The implication of this is higher attenuation of radio signal due to Ns during wet compared to the dry seasons’ months and as well as in Ilorin compared to Abuja. Correlation coefficients of -0.53, 0.98 and 0.53 were determined between (Ns) and; temperature, humidity and pressure respectively in Abuja while -0.30, 0.97 and 0.34 were determined between Ns and; temperature, humidity and pressure respectively in Ilorin. The overall findings of this work will be useful to radio engineers for the proper planning of reliable power budget over the study areas.</p> Nnenna Okoro Mmahi, Akinsanmi Akinbolati, Florence N.

The excessive inaccurate placement of seed at a required depth and intra - row distance, low field capacity and seed damage due to metering all envisage the need for a locally developed and cost effective multi-row animal drawn precision seed planter. This study focused on the design, fabrication and performance evaluation of a four row animal drawn maize seed planter. The fabrication was carried out at the Department of Agricultural and Bio-Resources Engineering Workshop, Ahmadu Bello University Zaria. The machine was evaluated in the experimental field of the department during the 2019 raining season. Three levels of planting speed ‘S’, three levels of hopper seed quantity ‘W’ and two levels of planting depth ‘D’ were assessed. The field experiment was designed in a 3×3×2 randomized complete block design (RCBD). The results showed that the effects of planting speed, seed quantity and planting depth were significant on the planting performance of the machine. The highest mean seed spacing, germination counts, field capacity and seed delivery rate of 23.50 cm, 88.5 %, 0.54 ha/hr and 20.7 kg/ha respectively were obtained. The developed planter has successfully eliminated the limitations associated with manual planting method, most locally developed planters, imported tractor drawn planters as well as increasing the field capacity of the planting operation.</p> K.

Cyclotetramerization of phthalonitrile in the presence of metal salt, Ni(II)) gave peripherally substituted metal phthalocyanine complexes. The structure of the synthesized compounds was characterized by different analytical tools such as <sup>1</sup>H NMR, UV-Vis, and FT-IR spectrophotometry and cyclic voltammetry. The disappearance of the C≡N stretching vibration from the IR spectra of phthalonitrile was observed at 2230 cm<sup>−1</sup>. The FTIR vibration results for C=O, C=C and C-O were 1712cm<sup>-1</sup>, 1615 cm<sup>-1</sup> and 1276 cm<sup>-1</sup> respectively. Solubility of metal phthalocyanine complexes was found to be very low in common laboratory solvents such as tetrahydrofuran (THF) and dimethylformamide (DMF). The electronic spectrum of NiPc in dimethylformamide (DMF) showed intense Q absorption at 690 nm. UV-Vis spectra of phthalocyanines showed electronic spectra with two strong absorption bands, Q and B bands. The Q band was found in 600–750 nm and B at 300–400 nm for both. The thermal stability of the phthalocyanine derivative was checked by T.G.A and the degradation was observed to start at 309 <sup>oC,</sup> which showed that the complex could withstand relatively high temperature. It could therefore be concluded that the metal phthalocyanine prepared in this study showed suitably high thermal stability and can be used for various applications</p> Aminu Dauda, Abdul Ademola Olaleye, Hamza Badamasi Copyright (c) 2021 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/796 Tue, 25 Jan 2022 14:31:10 +0000 OPTIMIZATION OF COAGULATION EFFICACY OF BANANA STEM JUICE IN WATER TREATMENT https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/735 <p>This work investigates the optimization of coagulation efficacy of banana stem juice as plant natural coagulant in treatment of raw water.

Jar test laboratory scale studies was performed and the result analysed statistically to study the effects of pH, retention time and coagulant dosage on coagulation. The coagulation efficacy was achieved at pH 6.5 with percentage removal of 58.065 % after 60 minutes retention time with dosage of 7.5mL/L. Firstly, before carrying these processes, the raw water sample was characterized to ascertain the initial concentration of the parameters before the jar test. Analysis of variance (ANOVA) was used to evaluate the significance of the model and the variables. The model F-value was 12.06 which implies that the model is significant and that there is only a 0.68% chance that such a Model F-value could occur due to interference. Also, values of "Prob &gt; F" were (0.0062) less than 0.0500 indicating that the model terms are significant. It could be concluded that Banana Stem Juice showed tremendous potential as a bio-coagulant for water treatment purposes and could be applied in the pre-treatment stage prior to secondary treatment.</p> Andrew Owoicho, Shaibu-Imodagbe, I.

It provided insight on the underlying socio-economic factors influencing farmer’s decision to adopt education and irrigation technologies in the study area. A structured questionnaire was administered for selected farmers. Results obtained revealed that 94% of farmers were small holders with low level of education indicating that farming in the study area is highly dominated by traditional farming system that results in lower yields. It also indicates 87% of farmers were within the economic active age of 20 – 50 years. Farming experience, fragmented land holdings and poor extension services were directly related to the acceptance farmer education and adoption of irrigation technologies. The study concluded that training and educating small-scale small scale farmers that form the bulk of farming community in Nigeria are viable solutions to securing household food security, diversification of source of income and reducing rural poverty</p> Aminu Saleh, R.

TO BITTER LEAF (VERNONIA AMYGDALINA DEL.) LEAF, STEM AND ROOT AQUEOUS EXTRACTS https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/798 <p>This study was carried out to assess the effect of leaf, stem and root aqueous extracts of <em>Vernonia amygdalina</em> on seed germination, growth and yield performance of <em>Sesamum indicum</em>. The aqueous extracts of the three plant parts were applied at concentrations of 25%, 50%, 75%, and 100% to sesame seeds in petri dish and compared with seeds treated with distilled water (control). The percentage of germinated seeds and lengths of radicle and plumule were measure within 10 days of sowing. The different concentrations of leaf, stem and root extracts of <em>Vernonia amygdalina</em> were applied to the seedlings of <em>Sesamum indicum </em>grown in pots and arranged in Complete Randomized Design (CRD). Data were obtained for number of germinated seeds, lengths of plumule and radicle while number of leaves, height of plant, stem girth, leaf length and leaf breadth were taken at 2,4, 6 and 8 Weeks After Planting (WAP). All data pooled were subjected to one way Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT) is used to separate means. Significant reduction in germination percentage of sesame seeds was recorded in sesame grown with 100% concentration of aqueous stem extracts of <em>Vernonia amygdalina </em>(78.33%) which indicates inhibitory effect of the extract at the concentration. 25% aqueous root extracts of <em>Vernonia amygdalina</em> significantly stimulated early growth of the shoot (1.70cm) and root (1.60cm) in sesame seed. In this study, growth and yield of sesame were enhanced by 50% root extract of <em>Vernonia amygdalina</em>. This suggests that intermediate concentrations of</p> Gbenga Olorunshola Alege, Musa Ozigi Yakubu, Deborah Tini Egilla, David Franklin Igata, Usman Ibrahim Aliyu, Danlami Dauda Copyright (c) 2021 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/798 Tue, 25 Jan 2022 15:03:58 +0000 EVALUATION OF THE LEVEL OF ECONOMIC EFFICIENCY OF IRRIGATED TOMATO PRODUCTION UNDER KANO RIVER IRRIGATION PROJECT, NIGERIA https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/799 <p>The broad objective of the study was to evaluate the Level of Economic Efficiency of Irrigated Tomato Production under Kano River Irrigation Project, Nigeria. A multi-stage sampling techniques was used to select 213 irrigated tomato farmers. Primary data was used and were collected using well-structured questionnaire. Data collected were analysed using descriptive statistics such as frequency, percentages and data. The result of the analysis revealed that the average economic efficiency of the irrigated tomato farms was 67%. This indicates that irrigated tomato farms were economically inefficient. It can be concluded that all the three categories of irrigated tomato farms were economically inefficient with large irrigated tomato farms having the highest economic efficiency of 67% in the study area. It is therefore recommended that agricultural extension workers should be provided to disseminate research finding and educate irrigated tomato farmers on ways of improving their economic efficacy</p> Bashir Sa'ad Ahmed, Zakari Abdulsalam, Abdullahi Damisa Maiyaki Copyright (c) 2021 FUDMA JOURNAL OF SCIENCES https://creativecommons.org/licenses/by/4.0 https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/799 Tue, 25 Jan 2022 15:15:29 +0000 ASSESSMENT OF NATURAL IONIZING RADIATION IN TWO TERTIARY INSTITUTIONS OF NIGER STATE https://fjs.fudutsinma.edu.ng/index.php/fjs/article/view/800 <p>Background ionizing radiation attributed to natural sources has over the years been at increase due to increase in infrastructural facilities and population inducing more human activities within campuses. This called for very great concern because of it effects on the human at higher exposure doses. Consequently, the Assessment of the Natural Ionizing Radiation was carried out at Ibrahim Badamasi Babangida University, Lapai (IBBUL) and Niger State Polytechnic, Zungeru (NSPZ) with approximate populations of 7000 and 5200 students respectively. A portable Geiger-Mueller dosimeter was used at 19 different locations within the two tertiary institutions. The results revealed the Dose Rate variation from 0.14 to 0.186 μSv⁄hr, at IBBUL, while at NSPZ the variation was from 0.12 to 0.158 μSv⁄hr. For all the locations the mean Dose Rate was 0.154 μSv⁄hr with a standard deviation of 0.0195 μSv⁄hr. Generally, average Annual Effective Dose Rate obtained is 0.27 mSv/annum which fell within the recommended alarming limit of 1 mSv/annum given by the International Commission on Radiation Protection (ICRP) for non-occupational population exposure. This implied no adverse impact on the tenements within the two tertiary Institutions. However, part of the recommendations is that more work needs to be done on the soil to characterize the areas for possible radioactive source deposits which may be up to alarming magnitude in the near future.</p> Yusuf Tanko Usman, A.

There are ways to remove noise, the switching scheme is an outstanding method when equated to others, it initially segregates the noisy pixels and then filters them. Boundary Discriminative Noise Detection (BDND) is a type of algorithm that uses the switching method and is good for impulse noise detection, many works have been presented using several enhancements to detect noise from images using BDND. In this paper, we present a detailed outline of impulse noise and noise removal techniques by looking at over a decade of research conducted to establish a fundamental understanding of the Boundary discriminative noise detector algorithm used in image denoising. We analyzed 19 relevant papers through Google Scholar, focusing on three aspects: the methods for detecting noisy pixels, the type(s) of noise, and the major challenges. We found that many of the image denoising methods still use BDND and at least one algorithm is developed yearly except for 2017 to 2021, indicating the algorithm is significant in the field of image denoising. Furthermore, we wrap up the survey by highlighting some research challenges and offering a list of key recommendations to spur further research in this area.</p> Baththama Alhassan, M.A Bagiwa, A. F.

Consumption of aflatoxins contaminated grains can lead to complicated health issues that can lead to death. Aflatoxins are secondary metabolites commonly produced by <em>Aspergillus flavus</em> and<em> Aspergillus parasiticus</em>. They were reported to disturb foetus development, causes changes in living cells, suppresses the immune system and causes many forms of cancers. Aflatoxin B<sub>1</sub> was classified under group I carcinogens by the International Agency for Research on Cancer. Aflatoxins contamination affects food security and can hinder international trade due to the strict ban enforce by many nations. Contaminations were reported in raw and processed grains (including ready-to-eat), milk and meat of farm animals and human breastmilk and blood. Major causes of grains aflatoxins contamination are wrong harvesting time and method, improper drying, poor storage and processing and higher moisture in the grains. Literature was gathered through an online search on Google Scholar, attention was given to the articles published in the last 5 years. Causes of fungal contamination, aflatoxins production and their control measures were deliberated, possible means of mitigating aflatoxins contamination through consumption of food grains were also recommended</p> N.
