Nigeria Paper Currency Serial Number Pattern Recognition System for Crimes Control

Only secured and conducive environment void of robbery, kidnapping, fake currency and all forms of insurgencies will foster production and distribution of goods, investment and saving that enhance national economic growth and development. This is a mirage in a country generally believed and tagged the giant of African; Nigeria. Crime, in whatever name or nomenclature, has a significant negative impact on the welfare and economy prosperities of our society. The urge to get rich promotes Crime like armed robbery, kidnapping for ransom and production of counterfeit banknotes to mention but a few. Innocent people have suffered psychological distress, fear, anger, depression, physical harm, financial loss and in most cases untimely death during the operations by these hoodlums. Banks, Cash-In-Transit Vehicle, and ATM points are often robbed by gangs in search for paper currency. Kidnappers as well demand for paper currency as ransom while some other gangs are involved in the production of counterfeit banknotes so as to enrich themselves no minding the negative effect on the nation’s economy.  The banknotes collected during the operations by the hoodlums are taken to banks. Yet, the banks will not detect or recognize any of these notes which attest to the fact that our system lacks check and balance. The system is very porous without a recourse to this era of technology when machine is trained to do virtually everything for our convenience. Currency as an entity has a unique identification number. The identification number is an alphanumeric currency issuance of about 10 digits comprises two (2) capital letters and eight (8) numbers usually positioned at a strategic location on either front or back of the 5, 10, 20, 50, 100, 200, 500 and 1000 naira notes. It is a reliable and intelligent system developed to track banknotes unique identifiers numbers- serial numbers, in order to control financial related crimes.

Microbiota of gills and antibiotic susceptibility patterns of bacteria isolates from Clarias gariepinus in different holding facilities

Gill is a key respiratory and excretory organ in fish as it provides oxygen need for survival and excretes waste products. However, gills can be infected with pathogenic and opportunistic bacteria leading to increasing fish morbidity and mortality. This study was carried out to isolate, estimate and identify bacteria on the gills of Clarias gariepinus reared in different holding facilities. The susceptibility patterns of the bacteria were also studied using 10 antibiotics commonly used in pisciculture in Nigeria. A total of 84 bacteria belonging to 12 genera were isolated from the gills of 75 Clarias gariepinus. Gram-negative bacteria isolated included Salmonella species (3.6%), Pseudomonas species (7.1%), Aeromonas species (2.4%), Escherichia coli (13.1%), Proteus species (11.9%) Klebsiella species (3.6%), Citrobacter species (4.8%), and Shigella species (3.6%). Gram-positive Corynebacterium species (3.6 %), Staphylococcus species (20.3%), Bacillus species (19.0%) and Streptococcus species (7.1%) were also isolated. The result showed varying bacteria species when considering the different holding facilities. Greater than 50 % of Gram-positive and Gram-negative bacteria isolated were resistant to 5 and 6 different antibiotics respectively while greater than 80 % of all the bacteria were resistant to ≥ 3 antibiotics. The presence of these bacteria in fish predict subsequent impediment in pisciculture and may lead to socioeconomic losses, environmental contaminations and high public health risk. This study calls for concern and an urgent intervention on antibiotic stewardship among fish farmers. Keywords: Antibiotics resistance, Clarias gariepinus, Fish farms, Gills microbiota, Kaduna stat

The Effects of Storage on Sachet Water Quality in Ogun State, Nigeria

The purpose of this study is to investigate the effect of storage on the physicochemical status and bacteriological quality of sachet water produced and sold in Abeokuta metropolis, Nigeria. Ten brands of sachet water were collected within 24 hours of production and stored at ambient temperature. Sub-samples were drawn from the stock samples immediately for physico-chemical and microbiological analyses and after two months. Physical parameters were determined by instrumental methods. Cationic and anionic constituents were determined by standard titrimetric and spectrophotometric methods, trace and heavy water were determined by Atomic Adsorption Spectrophotometer. The study revealed that all the brands of water analyzed were physically and chemically wholesome and met the WHO standards. Five brands (50%) of the water had total viable and coliform count above the recommended count of 100cfu/m and zero cfu/ml, respectively. pH values increased in all brands to acceptable WHO limits within 2 months of storage except for sample 3 and 4 which decreases below the acceptable limit. Majorly dissolved oxygen and nitrate values decreased through the investigation period. Total and faecal coliform appeared in 50% of sachet water samples analyzed immediately after production and were no longer detected after storing for two months except for sample 4. Results of the experiment indicate that 60% of the brands analyzed met the WHO guideline limit for drinking especially for the physico-chemical parameters while the majority failed in the microbiological essay when stored at ambient temperature for the two-month investigation period

Evaluation analysis of a developed solar refrigerator using conventional refrigerant for rural and medical applications

This paper study the performance evaluation of a refrigeration system that operates on solar energy as alternative source of power to enhance the refrigerating effect, coefficient of performance (COP), preservation of perishable items and short time drug such as vaccine, to remote communities and parts of the urban settlement around the developing nations where there is no access to modern electrical source. The system was made from locally sourced materials using a conventional refrigerant HFC134a as working fluid to improve thermal efficiency and stability of the vapour compression refrigeration system. The COP of the system was enhanced by 8.67% when working with solar and with energy reduction of 2.38% respectively. In case the weather is cloudy or during the night hour when the energy generation is low, the refrigerator can work on battery for an average of 12 hours if fully charge during the day to avoid idle time of the refrigeration syste

Effects of Concentrate Supplementation on Performance Characteristics of Goats Challenged with Trypanosoma brucei

The influence of concentrate-feed supplementation on dry matter and nutrient intake and digestibility, nitrogen retention and body weight gain in goats challenged with trypanosomiasis was studied. Sixteen male West African Dwarf (WAD) goats (7.32 ± 0.70 kg) inoculated with 1.5 × 106 Trypanosoma brucei were divided into four treatment groups each of four replicates in a 56-day, completely randomized design experiment. Treatments consisted of varying intake levels (0, 50, 100 and 150 g/head/day) of a maize-based concentrate supplement (19.72 %; CP) to basal Panicum maximum hay (10.81 %; CP). Dry matter intake (g/head/day) of 211.77 ± 2.66, 215.14 ± 7.25, 253.28 ± 5.23, and 275.96 ± 3.65 obtained for goats fed supplement at 0, 50, 100 and 150 g/head/day respectively were different. Coefficient of crude protein or crude fibre digestibility was higher (p < 0.05) for goats fed the concentrate supplement at 100 or 150 g/head/day level than for those fed at 50 g/head/day or the control. Differences in feed nutrient intake and digestibility caused gradual improvement (p < 0.05) in body weight gain (g/head/day) from 8.39 ± 0.21 in the un-supplemented group to 18.21 ± 0.42 in goats fed concentrate supplement at 150 g/head/day. The results indicated a positive influence of concentrate supplementation on ability of the goats infected with trypanosomiasis to consume and digest feed nutrients for body weight gain. The 100 g /head/day level of supplementation was considered adequate
