The ability to track vehicles is useful in many applications including security of personal vehicles, public transportation systems, fleet management and others. Furthermore, the number of vehicles on the road globally is also expected to increase rapidly. Therefore, the development of vehicle tracking system using the Global Positioning System (GPS), Global System for Mobile Communications (GSM) modem, General Packet Radio Service (GPRS) and Google or Open street map respectively is undertaken with the aim of enabling users to locate their vehicles in real time with ease and in a convenient manner. The system will provide users with the capability to track vehicle remotely through the mobile network. This project presents the development of the vehicle tracking system's server and client software. Specifically, the system will utilize GPS to obtain a vehicle's coordinate and transmit it using GSM modem to the user's phone through the mobile network. The system is divided into two parts which are the tracking and monitoring part. The tracking part consist of GPS and an android/IOS mobile phone for navigation purpose. The GPS will provide information about the location of the vehicle. After receiving the location data from the web server, the data is monitored by a personal computer. After processing the data, the location of the vehicle can be viewed on the map.

The study was conducted to investigate phytochemicals, anti-nutrients and mineral compostions of Telfeira occidentalis and Cleome rutidospermas leaves. The High Performance Chromatography (HPLC) was used in the Quantitative analysis of Phytochemicals as well as the anti-nutrient contents while the Elemental Compositions was analysed using Atomic Absorption Spectrophotometer (AAS) (Buck Scientific). The antinutrients content analysed were as follows hydrocyanic acid (31.0±0.001 and 25.0±0.001), oxalate (570±0.004 and 740±0.003), phytic acid (7.50±0.002 and 9.20±0.005 mg/100 g), for T. occidentallis and C. rutidosperma respectively and  the values were all within the NAFADAC/WHO tolerable limit. The Minerals Compositions was found to be, Mn (1.684±0.40 and 0.718±0.31 mg/100 g), Zn (1.740±0.10 and 1.570±0.31 mg/100 g), Fe (3.823±0.03 and 4.329±0.01 mg/100 g), Na (2.572±0.42 and 2.659±0.80 mg/100 g), Ca (74.405±13.60 and 29.677±13.50 mg/100 g), Mg (35.277±10.05 and 12.438±10.4 mg/100 g), Cu (0.049±0.03 and 0.044±0.01 mg/100 g) for T.  occidentallis and C. rutidosperma respectively. The presences of some secondary metabolites like alkaloids, flavonoids, terpenoids, tannins, cardiac glycosides and some essential minerals shows that the plants can be alternative sources of medicine. The results of the antinutrients indicated that the samples are free of toxic substances which might cause ill health to the body. Though, the anti-nutrient contents found in both T. occidentallis and C. rutidosperma were low, it will still be safer if these leaves were boiled for about 5 to 15 minutes to reduce the anti-nutritional factors significantly.

This study was carried out to investigate the axial and radial variations of fibre characteristics of Bambusa vulgaris. There were eighteen treatments for both axial and radial variations. The treatments were replicated three (3) times, in Complete Randomized Design (CRD). The experiment was carried out at the Wood Anatomy Laboratory of the Department of Forest Product Development and Utilization, Forestry Research Institute of Nigeria, Ibadan. Three samples (3) stands of B. vulgaris were randomly selected. Samples collected were cut into 10cm discs at 25%, 50% and 75% of the total height (axial positioning). The samples discs were partitioned into two zones which are core and peripheral (bark) layers. From each of the disc, 3 slivers were obtained both from radial and axial positions. Slivers obtained were macerated with an equal volume (1:1) of 10% glacial Acetic acid and 30% Hydrogen Peroxide (H2O2) at 100 ±2°C. The resulting image on light microscope screen was measured for fibre length, fibre diameter and lumen width.

At 50% sampling height and at outer layer, the highest fibre length of 3.25 mm, followed by 3.06 mm of bamboo sample stand 3 while the least 2.28 mm was recorded in sample stands 2 of 75% axial positioning and at peripheral layer. The lumen width ranged between 3.52 × 10-3 μm to 4.46 × 10-3 μm in the radial direction from the core to the peripheral (bark) of the bamboo. The result obtained for mean values of fiber diameter along the bamboo height ranged from 3.53 × 10-3 µm to 4.46 × 10-3 µm across the three (3) bamboo stands, sampling height and radial direction sampling respectively.

Among the fibre positioning, the fibre collected from 50% of the sampling height have higher fibre diameter, lumen width and fibre diameter at the peripheral region compare to the others.

As a result of the limitations of physical and chemical methods for monitoring pollution, interest on the more reliable biological monitoring intensified over the past four decades. Soil microarthropods, specifically the free-living mites (Cryptostigmata, Mesostigmata, Prostigmata) and Collembolans were used as monitor (ability to withstand pollutants) and indicator (sensitive to pollutants) species in the Eastern Niger Delta. Study was undertaken in the Western Niger Delta (Delta State) across three eco-vegetational zones (freshwater swamp forest, Mangrove swamp forest, Lowland rainforest) in the area to determine if these ecosystem health indicators were widely distributed in these zones. Collections were made during the rainy season over a 4-month period. A modified Berlese-Tullgren funnel was used for extraction of microarthropds. Free-living mites: Cryptostigmata (Oribatida) – Archogozettes magnus, Opiida sp., Annecticarus sp., Bicyrthermania negeriana, Cephalida sp., Scheloribates sp., Galumnida sp., Mesostigmata (Gamasida) - Asca sp., Trichuropodida and Collembolan – Paronella sp., were widely distributed across the eco-vegetational zones. Oribatids were most abundant across eco-vegetational zones. These mesofauna contained the full complement of monitor and indicator species. It is therefore possible to use these mesofauna for biomonitoring of oil pollution across the Niger Delta (eastern and western sectors), Nigeria.

This study investigated the abundance and some morphometric parameters of lizards (Agama. agama, Hemadactylus. brookii, Trachylepis. affinis and Trachylepis. quinquetaeniata) in the University campus, Ile-Ife. The specimens were collected in five different locations in the University campus. The samples were collected with sweep nets in all the locations. A total of 624 specimen of lizards (324 of A. agama, 185 of H. brookii, 60 of T. affinis and 55 of T. quinquetaeniata) were caught in all the locations and external body measurement was carried out with the help of calliper. A. agama was found to be abundant in all the locations followed by H. brookii. The number of Skinks (T. affinis and T. quinquetaeniata) in the residential area was low but high in University parks and garden and markets. The morphometric parameters showed that A. agama was different in all the parameters measured compared to the rest specimens and it was expected since the specimens were not of the same family except the Skinks (T. affinis and T. quinquetaeniata). There were similarity in values of some of the measured body parts of H. brookii, T. affinis and T. quinquetaeniata. The Principal Components Analysis (PCA) showed that all the specimens differ in Tail length, Tail width, and Trunk length. In conclusion, the abundance of the Lizards in the University call for concern because their waste can contaminate food and cause infection since they are hosts to a number of parasites.
