PERFORMANCE AND FAILURE OF SOLAR BOREHOLES FOR WATER SUPPLY IN KUMBOTSO LOCAL GOVERNMENT AREA KANO STATE, NIGERIA

Abstract: 

Assessment for the performance and failure of solar boreholes was undertaken in Kumbotso local government area of Kano state. This is in line with frequent failures of solar boreholes for effective water supply in the study area. Seven wards were selected for the study. Sample of 151 respondents were interviewed. Data was collected through field observation, use check list, interview and focus group discussion. The data was analyzed using simple statistics such as totals, means, standard deviation and percentages. Likert scale of measurement was also applied in analyzing the responses on performance, failure and level of utilization of boreholes. Student’s ‘t’ test was used to find out whether there is significant difference or not between functioning and nonfunctioning borehole in the study area. Chi-square test was also use in the analysis of problems and solutions. Result shows that there are 26 solar boreholes out of which 11 are functioning and 15 are not functioning it is established that there is significant difference among the eight study wards in terms of functioning and non-functioning solar boreholes at 0.05 level of significant. It indicates that 68 (46%) of the respondents said community members are the major stake holders. The result shows that most of the parameters are fairly satisfactory with means of 0.50 – 1.27. Result also shows that computed means of all the problems facing water supply trough solar boreholes are below the Likert scale of satisfaction of 2.80 – 3.42 and there is no significant association among the problems affecting solar boreholes performance for water supply in the study areas at 0.05 level of significant. Findings shows that provision of full security as a major solution to the problem of solar boreholes performance for water supply with 55 responses (36.45%). Result shows that there is no significant association among the major solutions to the problems. With particular reference to findings of the research it is recommended among other issues that adequate security should be provided to prevent solar panels, sumo and other important components from being stolen for effective performance and water supply.

A REVIEW OF NATURAL PRODUCTS CHEMISTRY-THEIR DISTRIBUTION, EFFECTS AND USAGE TO MAN

Abstract: 

Natural products are naturally occurring compounds that are end products of primary metabolites; often they are unique compounds for particular organisms. They are non-nutritive plant chemicals that have protective or disease preventive properties. They are nonessential nutrients, meaning that they are not required by the human body for sustaining life. The most important of these phytochemicals (secondary metabolites) are alkaloids, tannins, saponins, steroids, flavanoids, terpenoid and cardiac glycosides. Their important physiological effects on humans and other animals are reviewed.
Keywords: Natural products, uses, phytochemicals, man and chemistry.

RADIOLOGICAL SAFETY ASSESSMENT OF SOIL SAMPLES FROM SOME WASTE DUMPSITES IN KANO METROPOLIS

Abstract: 

Investigations were carried out to determine the presence of natural radionuclides in some selected dumpsites and evaluate the hazards these may have on the people living around the locations in Kano metropolis, Nigeria. Gamma-ray spectrometry with [NaI(Tl)] detector (Canberra, model 727) at the Centre for Energy Research and Training, Ahmadu Bello University Zaria, Nigeria, was used to determine the concentrations of radionuclides in the soil samples randomly collected from study area. The results show that activities of 40K ranges from 242.15 to 697.51 Bq/kg, 226Ra ranges from 12.75 to 57.24 Bq/kg and that of 232Th ranges from 20.57 to 128.51 Bq/kg in all the analyzed samples. However, the results show that, the average value of 453.19Bq/kg of the activity concentration of 40K found in this study has exceeded the world average value of 400Bq/kg, and there was a higher activity concentration of232Th at all the dumpsites. The average values for radium equivalent, external index, internal index and gamma level index were 148.4Bq/kg, 0.401, 0.460 and 0.544 respectively in all the samples are lower than the suggested maximal admissible value of 370Bq/kg, 1,1 and 1 respectively. The average value of the absorbed gamma dose rates to gamma radiations is 67.84(nGy/h) for the samples, which was higher than the recommended world average value of 60 (nGy/h). However, the average annual effective dose was 0.028 (mSv/y) in the samples, and were lower than the world average 0.07 (mSv/y).

INCIDENCE OF PHYTOPHTHORA INFESTANT THE IRISH POTATO FAMINE FUNGI AT YANKABA MARKET

Abstract: 

Study was carried out to determine the fungal pathogens responsible for post-harvest losses of potato (Solanum tuberosum) on sale at Yankaba market. The investigation period lasted for five month between September, 2015 to January, 2016. Potato samples were collected and analyzed for the presence of fungal species using standard methods. Fungal infection at Yankaba markets were found mostly to be due to Phytophthora infestant 20 (33.3%}, Alternaria solani 15(25%), Aspergillus niger 6(10%), Rhizopus stolonifer 9(1.58%), and Mucor spp 10 (16.7%). Although more colonies were recorded on Monday 28(46.7%) than Thursday exposure with 32 (53.3%) but the differences was not statistically significant (P>0.05) between the two sampling dates. This showed that date of sampling has no effect on the isolation of fungal colonies. However, the results of this study showed that fungal pathogens play a significant role in post-harvest loss of the potato at Yankaba market

SEGMENTATION AND RECOGNITION OF NIGERIAN LICENSE PLATE USING BOUNDING BOX AND TEMPLATE MATCHING

Abstract: 

The Number Plate Recognition (NPR) is a system designed to help in recognition of the character written on the number plates of vehicles. Before the recognition, a number plate has to be segmented. Segmentation is a process of partitioning digital images into multiple segments. In this work
thresholding of pixels values and Bounding Box were used for the segmentation. The recognition algorithm compares each individual character against the complete alphanumeric set using template matching. The matching process moves the template image to all possible positions in a larger source image and computes a numerical index that indicates how well the template matches the image in that position. Before the Segmentation and Recognition algorithm is applied, the License must be localized correctly using localization algorithm.
