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.

EFFECTS OF HEAT TREATMENT ON PROXIMATE COMPOSITION OF WATER MELON SEED (Citrullus lanatus) FOR POSSIBLE UTILIZATION IN FISH FEED FORMULATION

Abstract: 

This study examines the effect of heat treatment on the proximate composition of watermelon seed (Citrullus lanatus) using varied period of time for toasting (0, 20, 40 and 60 mins) respectively at a constant temperature of 1200c. The proximate composition of the seed toasted for 0 min (raw) showed that the seed had moisture content of 11.40%, Crude protein content of 20.50%, Fat content of 16.60%, Ash content of 0.74%, and Total Carbohydrate of 51.96%. Seed toasted for 20min showed that the seed had

FISH SMOKING EFFICIENCY OF TRADITIONAL SMOKING KILN (OPEN DRUM) AND FUTY IMPROVED PROCESSORS (OVEN

Abstract: 

The rate at which dryness occurred in fish varies considerably with these processors. Fish species preserved were Clarias, Heterobranchus, Synodontis, Tilapia and Hydrocynus species (whole, split and cut). Traditional Smoking kiln (open drum) and Federal University of Technology Yola (FUTY improved processors), were used. Firewood and sawdust were used as source of smoke and heat to the fish in an open drum processor and charcoal were used as source of heat to the fish in the FUTY improved processor (oven) at a time interval of two hours in three different occasions after which, weight loss was measured. Fish products appeared charred and burnt in an open drum kiln with a shorter shelf life due to excessive (uncontrolled) heat supply. In the ovens (FUTY Improved processor), the rate of dehydration was slow. However, fish products appeared golden brown making it attractive to the consumers. This was due to the even distribution of heat in the processor. Therefore, there is significance difference (p > 0.05) between traditional smoking kiln and FUTY improved processor (oven).
