A lot of mishappenings occur on the road every day .Therefore the need of security and monitoring is developed .To resolve such problems, a system is developed using GPS and GSM technologies and an application is introduced in the research work. The ability to accurately detect a vehicle location and its status is the main goal of automobile trajectory monitoring systems.& also The high demand of automobiles has also increased the tra...
ABSTRACT This study analyzes and compares the simulated performance of a 3.2 kWp grid-connected photovoltaic system. The system is located within coordinate of 12°15’N 7°30’E, at Government Day Secondary School Kofan Yandaka Katsina State Nigeia. The system consists of 14 Mono crystalline silicon modules connected in two strings of 7 seriesconnected modules, each facing north at a fixed tilt of 20° .The simulation is performed using Meteonorm generated weather data. The performance of ...
ABSTRACT Biometric technology is a technique that is capable of uniquely identifying a person through his/her characteristics features. The use of this approach is gaining ground in recent times, particularly in higher institution of learning where impersonation is currently at alarming rate. The technology offers a reliable solution for solving recognition problem through features such as: fingerprint, faces, iris, palm print etc. The main objective of this study is to implement a system tha...
Abstract Background: Cymbopogon species are widely used as herbal remedies by the traditional healers living in Nkonkobe Municipality for the treatment and management of skin and respiratory infections. According to our survey, the plants seem to be very important because of the higher demands. Methods: The leaves of C. validis and C. plurinodis were hydro-distilled and the resulted extracted oils were analyzed by GC/MS. Minimum inhibitory concentrations (MICs) ranging from 7.8 to 500.0 μg/m...
Abstract: Diarrhoea caused by Cryptosporidium is usually mild in immune competent individuals but severe in the young and those with underlying disease leading to compromised immunity. The conventional diagnosis of Cryptosporidium requires observation of the infective oocysts however, their tiny size yields indistinct results, thus limiting the effectiveness of the conventional diagnostic technique, modified Ziehl-Neelsen (ZN) differential staining. Consequent to the abovementioned limitatio...
Abstract: Sour figs have become a provincial demand in South Africa for the treatment of common infections. The plant has displayed antioxidant activity. The plant leaves were extracted with hexane, acetone, and ethanol using Stuart Sharker, UK. The extracts' antibacterial activity was evaluated by determining the MICs in a range of 7.8-500.0 μg/ml against ten strains using micro-well dilution. Cytotoxicity was evaluated with brine shrimp using the same concentrations. The hexane extract exh...
Abstract Background: Carpobrotus edulis (Mesembryanthemaceae), also known as igcukuma in Xhosa language is a medicinal plant used by the traditional healers to treat common infections in HIV/AIDS patients. Based on this information, we researched on the plant phytoconstituents, as well as its inhibitory effect using aqueous and three different organic solvent extracts in order to justify its therapeutic usage. Methods: Antioxidant activity of the extracts were investigated spectrophotometri...
Abstract Background: Mesembryanthemum edule is a medicinal plant which has been indicated by Xhosa traditional healers in the treatment HIV associated diseases such as tuberculosis, dysentery, diabetic mellitus, laryngitis, mouth infections, ringworm eczema and vaginal infections. The investigation of the essential oil of this plant could help to verify the rationale behind the use of the plant as a cure for these illnesses. Methods: The essential oil from M. edule was analysed by GC/MS. Co...
Background and Objective: Carpobrotus edulis has become one of the most recognized herbal plants in the Savanna Regions of Eastern Cape and Western Cape in South Africa. This study analyzed the foliar morphology and elemental composition of the plant Carpobrotus edulis (L.) bolus. Materials and Methods: Fresh leaves of the plant were investigated using the JEOL (JSM-6390LV) Scanning Electron Microscope (SEM). The elemental composition of the leaf was determined by Energy Dispersive X-ray Spe...
ABSTRACT Simple population growth models involving birth rate, death rate, migration, and carrying capacity of the environment were considered. Furthermore, the particular case where there is discrete delay according to the sex involved in the population growth were treated. The equilibrium and stability analysis of each of the cases were considered also. The stability analysis shows that the discrete delays in the population growth lead to instability in the growth. TABLE OF CONTENTS CERTIFI...
ABSTRACT Occurrence of overpressured formation is common in Tertiary basins (e.g. Niger Delta), which can result in geomechanical problems, such as “kicks”, loss of expensive drilling mud, blowout, stuck pipe, reservoir quality damage, wellbore instability etc. if it is not accurately predicted prior to drilling. This study did a critically re-evaluation of the two commonly utilized methods and practices involve in pore pressure work in the industry. The main aim was to accurately predict...
ABSTRACT Cenozoic sediments outcrop in the Niger Delta Basin. Deposits in the Basin thicken southward (down-dip) but thin northward (up-dip) around Bende – Umuahia area where approximately 260 m thick exposure was logged from base to top. Sieve analysis and petrography were carried out to establish the depositional settings of sediments while palynological analysis was undertaken in order to identify palynomorphs and establish their biozonations, determine and correlate age of sediments, as...
ABSTRACT A fully automated X/S band Mission Control Centre (MCC) for the Nigeriasat-2 (N2) and Nigeriasat X (NX) satellites was constructed in Abuja. The construction of the MCC consisted of the installation of the appropriate size of antenna and computer systems used for the control of the entire satellite mission. The MCC of N2/NX consists of three main segments: the ground station (GS) used for direct communication link with the satellite, the mission control suit (MCS) used for mission co...
Abstract A nanocrystalline and porous p-Polyaniline/n-WO3 dissimilar heterojunction at ambient temperature is reported. The high-quality and well-reproducible conjugated polymer composite films have been fabricated by oxidative polymerization of anilinium ion on predeposited WO3 thin film by chemical bath deposition (CBD). X-ray diffraction analysis of the deposited WO3 films revealed that as-deposited film was amorphous; however, an amorphous-to-crystalline phase transition was observed by r...
ABSTRACT The study was aimed at examining the spatial pattern of industrial production subcontracting in Onitsha Metropolis Anambra State Nigeria. Data were collected from documentary materials, questionnaire, in-depth interviews and field observation and were analysed using percentages, mean, standard deviation, nearest neighbour analysis and principal component analysis. The results of the study revealed that production subcontracting by firm size was more prominent in small and medium scal...
