Communication Engineering Department, Ahmadu Bello University, Zaria, Nigeria
The global changes in the area of multimedia and the rapid acceptance of graphic images in mobile networks makes image and video compression the most important aspect of digital image processing. The objective of image or video compression is to reduce the size of the image or video (redundancy) with little or no change in terms of image or video quality for an effective transmission and storage. This paper presents analysis on wavelet transforms compression technique using pixel intensity. A total of six (four acquired and two benchmark) sample video data were used to implement the achieved technique. To compensate for the quality of the degraded output of the images, we applied the luminance enhancement model. Simulation results showed that, the achieved method is efficient with improved contrast pixel intensity. It has been observed that the enhanced LWT (E-LWT) compression technique produced the highest PSNR values in all the six video samples, followed by enhance DWT (E-DWT). For the respective individual sample video frames of NAERLS1.avi, NAERLS2.avi, NTA1.avi, and NTA2.avi, the E_LWT produced PSNR percentage improvement of 12.59%, 5.10%, 4.71% and 1.93% over E-DWT and for the benchmark video frame of Akiyo.avi and Forman.avi, the E_LWT also produced a percentage improvement of 14.46% and 5.31% over E-DWT.

Global solar radiation and its components are important parameters for the design and performance evaluation of systems utilizing solar energy. An analysis has being made to assess the predictive accuracies of six existing theoretical models for computing monthly global solar radiation for Plateau State using the meteorological parameters which cover 12 months period . Root Mean Square Error (RMSE), Mean Bias error (MBE) and Mean Percentage Error (MPE) methods were used for the assessment. However, based on this RMSE, MBE and MPE, model one (Angstrom type equation by Frere) and model three (First order Angstrom Type Equation by Ogolo 2000) gives a more satisfactory agreement with the measured results of the monthly solar radiation. And hence they are recommended for estimate of solar radiation in plateau state and its neighbouring states.

Livestock extension services have a vital role to play in livestock production, since it is the responsibility of extension service to disseminate improved technologies in livestock husbandry and management to livestock farmers apart from forming a link between research stations and farmers. This study was carried out to analyse the factors responsible for adoption of the livestock production technology in Bauchi state, Nigeria. Data were collected through questionnaires administered to seventy five randomly selected respondents. Data were analyzed using descriptive statistics, t-test and regression models. It was found that majority (97%) of the respondent attended one form of school or the other. Most, also (78.67%) of the respondents had farm size between 1-3 hectares. Also majority (78.67%) belongs to one organization or the other. And greater percentage of the respondents adopted poultry production, feed and feeding improvement and livestock fattening. The result of the t-test between yield of respondents on number of animals before and after access to extension services shows that there was a significant (p<0.001) difference in the number of animals reared. It also indicated that farm size was significant (p<0.001) while household size, years of farming experience, membership of organization and extension contact were significant at (p<0.005). The major constraint to adoption of animal production technologies were shortage of extension agents, high cost of technology and lack of access to credit facility. The major pre-requisite for the improvement of extension service are employment of more extension agents or workers and adequate training. Adequate agricultural credit to farmers at low interest rates will enhance their adoption of crop and animal production technologies.

Momordica balsamina and Diospyros mespiliformis leaf extracts were subjected to phytochemical screening. The antimicrobial activity of the plants extracts was carried out against Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia using agar well diffusion method. Momordica balsamina methanol extract had inhibition zones of 3.3mm, 4.2mm, and 7.0mm against E. coli, S. aureus and K. pneumonia respectively, while the ethanol extract had inhibition zones of 2.0mm, 4.1mm and 4.0mm against the test organisms respectively. The aqueous extract had the lowest inhibition zones of 1.4mm, 2.4mm and 2.1mm respectively. Diospyros mespiliformis methanol extract had the highest inhibition zones of 10.2mm, 12.2mm and 10.3mm against E. coli, S. aureus and K. pneumonia respectively, followed by their ethanolic extract which had 10.6mm, 10.3mm and 7.6mm against the respective organisms. The aqueous extracts of Diospyros mespiliformis did not inhibit K. pneumonia. The phytochemical screening indicated the presence of tannin, phenols, flavonoids, alkaloids, saponins, glycosides and terpenoids in both Momordica balsamina and Diospyros mespiliformis. The quantitative phytochemicals for both Momordica balsamina and Diospyros mespiliformis using spectrophotometric analysis revealed total phenol (1.208mg/g and 1.336mg/g), flavonoid (1.8mg/g and 1.4mg/g), ascorbic acid (0.071mg/g and 1.208mg/g) alkaloid (0.22mg/g and 0.03mg/g) and tannin (0.63mg/g and 0.92mg/g) respectively. The overall result indicated that Momordica balsamina and Diospyros mespiliformis leaves are potent antimicrobial preparations at least invitro and the quantititative bioactive constituents suggests antioxidant ability of both plants.

This paper creates awareness among researchers on the suitability of exergy analysis in energy auditing works and acquaints the personnel on whether the boiler is utilized maximally or not. Energy losses and exergy efficiency are two basic factors that are considered in studying systems like steam power plant. Though, energy losses (degradation) in a given system are commonly inevitable, it is also a fact that, because of the increased awareness of energy management globally, Governments were compelled to re-examine their energy policies and take drastic measures in eliminating waste. It has also sparked interest in the scientific community to take a closer look at the energy conversion devices and to develop new techniques to better utilize the existing limited resources.

With the rapidly increasing use of radioisotopes in research, therapy and radiation protection studies, the problem of accurate determination of the distribution of the energy imparted to biological tissues has greatly increased in importance. The absorbed doses in tissues due to X- ray point sources were computed as a function of exposure time, Photon energy and the distance between the source and target. The absorbed dose was found to increase linearly with exposure time. With the increase in Photon energy, the absorbed dose was found to increase almost linearly while it decreases exponentially as the distance between the source and the target was increased.

The use of machines in modern agriculture is highly accepted with no measures taken into consideration in relations to occupational hazards; this is due to the increasing demand of food and the need to meet the demands in agricultural productivity for sustainability. This research is carried out in order to review tractor noise in the agricultural and farming system in North-Eastern part of Nigeria and identify the common forms of hazards associated with the tractor noise in the industry. A secondary source of data collection was used during the study period. The result revealed that when the level of the sound in the tractor is very high or the exposure time is long the hair structure cilia that normally vibrate in process of moving the sound bend due to the loudness and it will not come to its normal position this lead to an induced hearing loss. Controls on how to manage the hazards were also given Farmworkers mostly believe in orthodox ways, rather than following the procedures as per safe operating training/techniques. This may involve different activities like operating machinery such as tractors, crane, excavator and manual handling which also increase the risk exposure. Nigerian Government is now focusing not only on crude oil as a source of its revenue but also agriculture which leads to high investment and extensive plans on agriculture in order to sustain its populace and generate national income. This study shows how tractor sound in Northeast Nigeria causes induce hearing loss and other health problems on the human body as result of too much exposure to the sound without health and safety measures.

SOLUTION OF NON-LINEAR DIFFERENTIAL EQUATIONS THAT MODEL POPULATION DYNAMICS USING THE LAPLACE TRANSFORM METHODS
Department of Mathematics and Statistics, University of Portharcourt, Rivers State.
This paper applied Laplace Transform Techniques to obtain solutions to non-linear differential equations that model Population dynamics. The new model identified four parameters that affect population growth, in contrast to the models in literature which considered only three parameters which are Births, deaths and overcrowding. The additional parameter is the epidemic. The solutions obtained in no overcrowding and no epidemic indicates a population growth. It shows that there exists a rise in the population abundance. But whenever the epidemic term is introduced into the model, there is a sharp decrease in population growth.
