    Abstract: A new re-dyeing practice has emerged and is fast spreading in urban Kano causing damage to the environment. This survey was carried out to assess selected fabric re-dyeing activity sites and their environmental impacts. This was achieved with the aid of designed questionnaire. Nine major dyeing sites in urban Kano: Kofar Mata, Chiranci, Karshen Waya, Rijiyar Zaki, Jan Bulo, Zawaciki, Kofar Na’isa, Karofin Zage and Goron Dutse dyeing pits were surveyed. The result revealed that individuals involved are males within the age range of 14 – 35years. The major sources of water are; pipe borne water, earthen dug wells and motorized borehole pumps. The dye wastewater is usually discharged untreated into street drains, ground surface and constructed pits. Individuals involved use protective measures such as face masks, hand gloves and traditional leather jackets. The dye powders, solutions and other constituents, when in contact with the skin cause serious burns, skin hardening and irritations. Inhalation of the gas emitted by the dye solution causes stomach upset and swelling of the body, which may sometimes be treated traditionally. The dye wastewater also destructs plantations/vegetation and inhibits survival of soil invertebrates such as earthworms. This calls for a general enlightenment to the users and general public on both the environmental and health risks of these substances

    Abstract: Multidrug resistance (MDR) exhibited by some strains of Escherichia coli may be due to acquiring mobile genetic element (R-plasmid) by the bacteria, or intrinsically induced by inappropriate use of antibiotics by the hosts.  Infection by such strains may result to prolonged illness and greater risk of death. The study evaluated the impact of curing on antibiotic resistance on selected clinical isolates of E. coli. Twenty clinical isolates of E. coli from our previous studies were re-characterized using conventional microbiological techniques. Antibiotic sensitivity testing was determined by disk diffusion method, MDR selected based on resistance to ≥ 2 classes of antibiotics. Multiple antibiotic resistance (MAR) index was determined as ratio of the number of antibiotic resisted to the total number of antibiotics tested and considered significant if ≥. 0.2. The isolates that showed significant MAR index were subjected to plasmid curing using acridine orange, thereafter, profiled for plasmid and the cured ones were re-tested against the antibiotics they initially resisted. Out of the 20 isolates, 19 (95%) were confirmed as E. coli, all (100%) of which were MDRs, which was highest against augmentin (78.9%) followed by amoxacillin (52.6%). However, after the plasmid curing only 6 (31.6%) out of the 19 isolates cured retained significant MAR index and the level of the significance had reduced drastically in 16 (84.2%) isolates. Conclusively, curing assay can completely eliminate R-plasmid acquired resistance. More studied on plasmid curing agents for possible augmentation of the agents into antibiotics may see the rise of successful antibiotic era again.

    Abstract: Nigeria has been characterized with shortage quantity in rice production due to inefficiency in the utilization of the available resources and post-harvest losses which account for about 20-25% of total production annually. This study was undertaken to examine the technical efficiency and post-harvest losses of rice farmers in MRVIS. Multi-stage sampling technique was used to sample 98 respondents. Data were collected using questionnaire and then analyzed using descriptive statistics, multiple regression model and Data Envelopment Analysis. The findings show that 73.4% of the farmers were within the age of 30-57. Similarly, farming was a male dominated enterprise with 93.0%. The farmers had a mean of 20 years in rice farming. The estimation of post-harvest losses confirmed that a total of 575kg/ha (8.44%) of total production was lost from harvesting to storage. There was ineffective utilization of production resources as the farmers could not achieve the optimal technical efficiency in rice farming. The regression analysis shows that harvesting, farm size, level of education and farming experience were the determinants of rice post-harvest losses in the area. It was recommended that Government should adequately install modern techniques for rice farming in MRVIS.

    Abstract: Coronavirus disease 2019 termed COVID-19 is a highly infectious and pathogenic illness caused by severe acute respiratory syndrome. Symptoms of COVID-19 range from mild to severe, in some cases leading to death. Early detection could help to monitor progression of the disease, mitigate spread of the disease and possibly reduce mortality rate. Computer-aided diagnosis systems are designed to complement health care systems and assist in the early detection of diseases. Currently, as it is not possible to test all citizens especially in developing countries with very large populations due to financial constraints and the standard of their healthcare facilities, the problem of identifying suspected cases and deciding laboratory test priority among citizens is evident and more pressing. Therefore in this study, we introduce an interactive Artificial Intelligent web system using the Multinomial Naïve Bayes algorithm with the aim of detecting warning COVID-19 symptoms and to provide fitting suggestions.  Furthermore, the study also evaluates the performance of the Multinomial Naïve Bayes based on the different holdout approaches experimented. The experimental results are promising as the Multinomial Naïve Bayes is shown to achieve high accuracy detection thus providing a reliable method to identify warning symptoms of COVID-19.

    Abstract: Learning theorist established the fact that learners are characterized according to their distinct learning styles. Investigating learners' learning style is important in the educational system in order to provide adaptivity and improve learning experience. Past researches have proposed various approaches to detect learning styles. Among unsupervised learning methods, the K-means clustering has emerged as a widely used method to predict patterns in data because of its simplicity. This paper evaluates the performance of K-means clustering in automatically detecting learners’ learning style in an online learning environment. The experimental results prove differences in learning thus characterizing learners based on learning style.

    Abstract: Soil sodicity is one of the major threats affecting the quality of soil globally. Soil sodicity problems remain a critical issue of concern as it adversely affects the yield of crops. This study assessed the effect of millet chaff in ameliorating sodium-affected soils at Thomas Irrigation Scheme in Kano, Nigeria. The experiment consisted of three levels of millet chaff application plus a control labelled (M1 = 1.44 kg/m2, M2 = 1.08 kg/m2, M3 = 0.68 kg/m2 and C = Control). The treatments were replicated three times in a Randomized Complete Block Design and rice seedlings were transplanted in each plot. The results showed a significant difference of soil quality parameters in the treated plots. The pH of soil samples was found to be 5.93, 6.067 and 5.5 for M1, M2, and M3 with percentage pH decrease from the control plot (C = 9.49) of 62, 64, and 58% respectively Similarly, the Sodium Adsorption Ratios were 5.723 for C, 0.188 for M1, 0.133 for M2 and 0.112 for M3. Statistical analysis revealed that there was a significant difference in soil quality indicators from plots treated with millet chaff and that of control. However, the study showed no significant difference in the yield harvested between the treated plots and the control. This suggests that using millet chaff for a sodicity amendment has no significant effect on the yield of a rice crop in the study area because all the prevailing soil properties are within the FAO acceptable range for growing rice.

    Abstract: Considering the high level of uncertainty in the foreign exchange market and the adverse effects of inflation in Nigeria, the need to utilize current data to work on appropriate models capable of predicting the future values of exchange rates and CPI has become necessary to guide monetary policy makers. This paper applies the techniques of Autoregressive Integrated Moving Average models to forecast the CPI and exchange rates of Nigeria using the dataset of monthly CPI and Exchange rates of naira against US Dollar from January 2010 to August 2022 obtained from National Bureau of Statistics. After the original series were appropriately differenced to attain stationarity, autocorrelation function (ACF) and partial autocorrelation function (PACF) were used to select a number of tentative models for parameter estimation. Based on selection criteria such as AIC, SBIC, HQC, R2 and Durbin Watson Statistics, ARIMA(1, 2, 0) was chosen as the best model for forecasting Nigeria’s monthly Inflation (CPI) and ARIMA(1, 1, 1) was selected as the most ideal model for forecasting monthly foreign exchange rates of Nigeria. The portmanteau tests carried out show that the residuals from both models are white noise which further confirms the adequacy of the fitted models. The results reveal that both inflation and Exchange rates of Naira against the Dollar will continue to rise. However, the rise in exchange rates for the short time is relatively steady. The findings from this study will furnish the monetary and policy makers with necessary information needed to reverse the expected trend

    Abstract: Sticky layer of Clarias gariepinus eggs cause the clumping of eggs immediately after fertilization, this create low oxygen, and increase pathogenic infection, thereby reducing fertilization and hatching rate hence reduces in mass production of C. gariepinus seed. Although various substances are use in the removal of the sticky layer, no information is available about the use of watermelon. Therefore, the present study, aim in exploring the potential of using watermelon in removing the sticky layer of C. gariepinus to enhance production. Fertilized eggs were treated with watermelon juice (T1) for comparison with 14 g L-1 milk solution (T2 as de-adhesion reference) and water as control (T0 as adhesion reference). The treatments were agitated with aeration for 30 minutes, rinsed with water, and poured on respective netted hatching trough, with water recirculation for incubation at 27 0C for 24 h period. Except for T0, no clumping of eggs was observed in the remaining groups. Slight variation in attaining a developmental stage among eggs was observed in eggs treated with watermelon. Hatching and survival rate in T2 are higher than T1 and T0 (P 〈 0.05). However, watermelon indicated the potential, as it removed the sticky layer while maintaining hatching and survival rate as in the control (T0) (P 〉 0.05), more should be explored before adoption of watermelon for de-adhesion and incubation of C. gariepinus eggs.
