Early detection of hidden intents and potential for future attacks or offenses is the main goal of intelligence and warning systems. Distance measurement of intrusive targets is important for indoor monitoring based on the detected intrusion target image. Calculating the distance between the target and the camera can provide the basis for the computer to determine the closeness of the invasion and probably provide information for the security alarm system. Consequently, this paper presents an image-based distance detection system for a non-zooming stationary camera observing object of known height above the ground. The image coordinates of the corresponding foot and head points of the object were manually detected and the internal and external parameters of the camera used were obtained automatically on receiving the image. Simulation results show that satisfactory measurements could be obtained where the absolute mean errors value via the proposed approach lie within 5.5%. © 2014 IEEE. Source

Four types of Kunun within Kaduna metropolis were analysed for their proximate nutrient compositions and microbial loads at ambient temperature. The four Kunun types (Kunun Aya, Kunun Dawa, Kunun Zaki and Kunun Gyeda) were different in term of the cereal starting materials. Chemical analysis revealed significantly (P < 0.05) higher total solid, total carbohydrate, protein and fats in Kunun Gyeda. The ash content was significantly (P<0.05) lower in Kunun Aya. The microbial counts on Plate Count Agar, Saboraud Dextrose Agar, Baird Parker's Agar and MacConkey Agar presented higher mesophilic bacterial count in Kunun Aya (3.90 × 101 cfu/ml), Kunun Dawa (2.20 × 101 cfu/ml) and Kunun Zaki (2.75 × 101 cfu/ml) compared to Kunun Gyeda (< 1.00 × 101 cfu/ml). All the values were however lower than the 1.0 × 103 cfu/ml acceptable microbiological limit for cereal based food. The staphylococcal count was higher in Kunun Aya, Kunun Zaki, and Kunun Gyeda than the 1.0 × 101 cfu/ml acceptable micrpbiological limit for cereal based food. Coliform count was least in Kunun Gyeda. However both coliform count and fungal count at the ambient temperature were below the 1.00 × 102 cfu/ml, the microbiological limit. The biological effects of the higher staphylococcal count were discussed. Source

The antimicrobial activities of bitter leaf (Vernonia amygdalina) extract and lime (Citrus aurantifolia) juice were compared in this study. A total of forty-five pure culture isolates, comprising of five organisms each of E. coli, Pseudomonas aeruginosa, Staphylococcus aureus, α-haemolytic streptococcus, β-haemolytic streptococcus, Klebsiella spp, Proteus mirabilis, Salmonella typhi and Shegella dysentariae were used for the investigation. The extract of bitter leaf and lime juice were prepared and serial dilutions of the extracts were impregnated into filter paper discs and allowed to dry in an oven at 45°C before use, in an agar diffusion method for the test. The results showed that five organisms (Pseudomonas aeruginosa, Staphylococcus aureus, E. coli, Klebseilla spp. and Proteus mirabilis) were susceptible to the crude extract of bitter leaf and lime juice, with a mean zone diameter of inhibition range from 18mm to 25mm. Pseudomonas aeruginosa, E. coli and Staphylococcus aureus were found to be more sensitive in-vitro to the bitter leaf extract than lime juice extract. The degree of zone of inhibition however differs, but bitter leaf extract exhibited higher inhibitory zone for many of the isolates than lime juice. The conclusion of this study, therefore, is that bitter leaf and lime juice extract are potential antimicrobial agents. Source

The effect of Nigella sativa (black seed) oil based diet on the management of Trypanosoma brucei infected rats was investigated. Brasitaemia was monitored and haematological and enzymatic studies were carried out on liver and blood of infected rats fed with diet formulated with black seed oil (treatment). Comparison was made with untreated infected rats and uninfected rats. The diet formulated with black seed oil extended the life span for 7 and 5 days for prophylactic and early stage feeding, respectively while the late stage feeding extended it by a day. The T. brucei-infection significantly (p<0.05) increased liver Glutamate Oxaloacetate Transaminase (GOT), Glutamate Byruvate Transaminase (GBT) and Gamma Glutamyl Transaminase (GGT). Serum GOT and GBT specific activities were also significantly (p<0.05) increased. However serum GGT activity showed no significant (p<0.05) difference in all the rat groups. While haemoglobin concentration, white blood cells, red blood cells, pack cell volume, mean cell haemoglobin concentration and platelet were significantly (p<0.05) reduced, as observed in the control and late stage feeding, by the infection, prophylactic and early stage feeding with diet formulated with N. sativa oil significantly (p<0.05) improved the parameters towards those obtained in uninfected rats. We concluded that the N sativa oil used in formulated diet could be involved in the improvement of the pathologic events observed in the T. brucei infected rats with prophylactic and early stage feeding. © 2011 Academic Journals Inc.

The eggfruit and shootborer (EFSB), Leucinodes orbonalis (Crambidae), is a major exotic pest of garden egg, Solanum gilo, causing enormous shoot and fruit damage in Nigeria. Information of the biology is required for effective management of this field pest. Life history of EFSB was studied on susceptible variety Lv Makurdi at 27±3°C and 85±4% RH data on developmental period of immature stages and reproductive parameters and sex ratio were collected. Developmental stages consist of an egg, five larval instars, pupa and adult. Developmental periods observed were eggs (5.93 days), 1st instar (1.00 day), 2nd instar (1.16 days), 3rd instar (1.48 days), 4th instar (2.63 days), 5th instar (4.46 days), pupa (11.2 days), female (4.14 days) and male (4.31 days). The reproductive parameters observed were incubation period (5.93 days), pre-oviposition period (1.19 days), oviposition period (2.71 days) and post-oviposition period (3.75 days). The Male to Female ratio was 1:2 and actual fecundity and potential fecundity per female were 123 and 207 eggs, respectively. Laboratory studies reveal that EFSB, Leucinodes orbonalis will complete its life cycle in 28.17 days. © 2013 Academic Journals Inc. Source
