The Sugar production data set is made up of 240 obtained from the Nigerian sugar company between January 1981 to December 2000 are used to forecast the time series data with the Holts-Winter (HW), the Support Vector Machines (SVM) and Hybrids models. To assess the forecasting performances of the models, the data are divided into two parts, the first part which is made up of 228 data sets are used for training (modeling) and the second part which is made up of the remaining 12 data sets are used for testing (forecasting). Statistical measures of performances such as Mean Square Error (MSE), Mean Average Error (MAE) and Coefficient of Correlation (R) are used for comparison and the result which shows that the hybrid model gave MSE of12332.97, MAE of 70.3411 and R of 0.5170 is the best model when compared with theSVM (MSE=15009.99), (MAE=88.6720), (R=0.5075) and H-W (MSE=19763.63), (MAE=92.8247), (R=0.4736). The result also indicated that the hybrid model recorded 34.4% improvement over HW model and 25.1% improvement over the traditional SVM model. This paper therefore proposes a hybrid methodology that exploits the HW and the SVM models in forecasting time series using the sugar production data.

Depo-Provera inhibits follicular development and prevents ovulation in its primary mechanism of action. (Hatcher, Robert A. 2004).The aim of this study was to evaluate and compare Effects of Depo Provera on the Morphology of heart as it is being used as a contraceptive. A single of Depo Provera contraceptive injection (150mg Medroxyprogesterone Acetate) intraperitoneally, at a dose of 75mg/ 100g body weight was given to ten matured Sprague Dawley rats daily for 10 days. Control matured Sprague Dawley rats of ten received the same amount of distilled water. After about 24hrs later, the rats were sacrificed, the rats heart were assessed morphologically. Weight of treated heart were compared with controls.Morphologically, Depo-Provera stimulated the heart by causing increase in their weight. This shows that Depo Provera has ability to bind with other tissues causing changes in their morphology. The form and structure of any living being are not constant during the whole of its existence, but undergo a series of changes from the commencement of that existence to its end, living beings have a Development. The history of development is an account of the anatomy of a living being at the successive periods of its existence, and of the manner in which one anatomical stage passes into the next.

Department of Geography and Planning, Faculty of Environmental Sciences, University of Jos, P.M.B. 2084, Plateau state, Nigeria.
The study examines the trend in the decline of the Jos Wildlife Park ecosystems. The research methodology used is literature search, face to face oral interview and direct field observation. Data collected were analysed using the descriptive statistical technique. The results from the analyses of the study show that significant changes have occurred in the abundance of species in the Jos Wildlife Park ecosystems. Habitat loss caused by deforestation is the leading cause of ecosystems decline in the Jos Wildlife Park. Human activities and factors such as the inequitable distribution of wealth and power, population growth, and urbanization are the causes of the decline in the parks ecosystems. Information gathered from oral interview with some of the staff of the Park reveals that some of the major causes of the decline in the park ecosystem include deforestation, bush fire, hunting activities, cutting down of trees for fuel wood and furniture, and clearing of land for agriculture and infrastructures. The results show that the increase in population of the communities surrounding the Jos Wildlife Park ecosystem posses a lot of pressure on the park. From the results of the analyses carried out, it was concluded that deforestation exists and has a significant effect on the decline of species on the Park. Conservation of forest resources is an important strategy for dealing with deforestation. Existing forest plantations should be managed sustainably and the cutting that does occur should be balanced by the planting of enough young trees to replace the older ones felled. It is therefore recommended that afforestation and mitigation by the government to ensure that cutting of trees for any purpose at the Jos Wildlife Park without planting of enough young trees to replace the older ones felled should be discouraged in order to salvage the ecosystem.

Moringa oleifera is considered one of the most useful plant trees, as almost every part of the moringa tree can be used for food and at the same time possessing medicinal properties. The aqueous extract of Moringa oliefera stem bark was investigated for elemental and phytochemical contents. Acute toxicity test and effects of the aqueous extract on red blood cell count (RBC), packed cell volume (PCV) and haemoglobin (Hb) concentration were carried out using standard procedures. The elemental contents included phosphorus, sodium, calcium, potassium, sulphur, magnesium, chloride, zinc, iron, manganese and aluminium. The phytochemical contents included carbohydrate, cardiac glycosides, saponins and alkaloids. None of the 5 rats used for the acute toxicity test died, indicating that the aqueous extract was not toxic to the rats even at 5,000 mg/kg body weight dose of the extract.The mean RBC count revealed a significant increase during the period of treatment and one week post treatment as compared to the control. There was a significant increase in PCV throughout the weeks of treatment. A dose dependent increase in Hb concentration was observed in weeks 1 and 2 of treatment. This may be adduced to the presence of iron and copper in M. oleifera leaves hence the justification for its traditional use in treating anaemic conditions. Conclusively, the aqueous extract of M. oleifera stem bark significantly increased red blood cells, packed cell volume and haemoglobin concentration in rats. Had wide safety margin, and possessed very useful phytochemical and elemental constituents.

There are different dimensions to the topic. Quality assurance. A theoretical consideration could be given in relation to the imput-process, output-model, its framework, plans adopted and others. But the issue that bothers the mind is how well has the symbiosis between the ‘product’ graduates, the departments turn out and services rendered to the society or better placed, how well have we (lecturers, scholars and practitioners) of TfD impacted on the citizenry that we are trained to empower on one hand and on the other hand, how well has governance either (Local, State or Federal) affected and changed the lives of the people for good. This paper shall diasect Oluwole-Ogba Community using the Theatre for Development method in order to gauge the level of Quality Assurance in that community.

The effect of problem-solving models on the performance and retention of students in solving quantitative problems in chemistry was the focus of this study. The design for the study was a pre-test, post-test non-randomized control group type. Population for the study comprised all the Senior Secondary 2 Chemistry students in Ikot Ekpene Local Government Area of Akwa Ibom State, Nigeria with a sample size of 120 students drawn from three intact classes in three randomly selected co-educational schools in the study area. Instruments used in gathering data for the study were the chemistry Quantitative problem-solving test (CQPST) used both as a pretest to test equality of groups before treatment, post test to assess the effect of treatment and as retention test after two weeks of treatment. The reliability coefficient of the instrument was established to be 0.79 using Pearson Product Moment Correlation (PPMC) by a test re-test approach. Three validated teaching packages were also used based on the three problem solving models adopted in the study. Treatment of quantitative problems was delimited to quantitative electrolysis data generated during the study were analyzed using the analysis of variance (ANOVA). It was observed that significant difference exist in the performance of students within the three treatment groups. And the group taught quantitative problem using the Search Solve Create Share (SSCS) problem-solving model performed higher than those taught using Selvarantnam - Frazer problem solving model (SPSM). The SSCS problem-solving model has greater facilitative effect on retention than the other two problem-solving models. It should therefore, be adopted for use by the Chemistry teachers and the authors and the Algorithm Problem Solving Model (APSM)
