ABSTRACT

The problems of rising social vices and poverty is associated with the increase in unemployment especially among the youths in Nigeria, more youths graduate from tertiary institutions of learning only to face limited employment opportunities that are difficult to secure. One of the solutions to the problems of graduates’ unemployment in Nigeria is the promotion of entrepreneurship and venture creation among students in tertiary institutions with a view to prepare them to be job creators and not job seekers after graduation. Entrepreneurship can help reduce increasing rate of employment if encourage in the right way. The study seeks to find out the prospect and challenges of entrepreneurship and venture creation among graduates of tertiary institutions in Nigeria with Plateau state as a case study. Using the survey method of data collection, sample size of 800 questionnaires were administered, 720 were retrieved and 620 valid questionnaires were analysed after sorting. The questionnaire combined multiple choice closed and opened ended questions. A multistage sampling was adopted where the state is stratified into three senatorial zones, 4 Local Government Areas (LGA) from each of the senatorial zones were identified and graduates of tertiary institution were thereafter randomly selected. The study adopted the descriptive and evaluation methods of data analysis to analyse data gathered. Findings revealed that entrepreneurship opportunities exist in Plateau State and that more graduates are willing to venture into business creation provided there is an enabling environment. The findings also found that entrepreneurship and venture creation in Plateau state is faced with a lot of challenges among which include challenging environment for entrepreneurship practice and venture creation, limited access to start-up capital for intending graduates, unfavourable government policies, inadequate infrastructures especially in the rural areas among other challenges. The study recommends entrepreneurship education be sustained in all tertiary institutions in Nigeria, creating enabling environment by policy makers to encourage new start-up business and small and medium enterprises, access to reasonable interest loan in financial institutions that is less stringent and infrastructures should be provided in the rural areas among other recommendations.

ABSTRACT: The yield, sensory characteristics and fatty acid content of oils extracted from African oil bean seeds at different maturation periods were investigated in this study. The seeds harvested from one-month development, two months’ development and exploded seeds were extracted, ground, dried and analyzed for the titratable acidity; and crude oil was extracted from the dried ground seed flour. The oil yield from raw seeds increased with periods of seed development, being 8.86% at one month, 27.8% at two months and 39.2% at full maturity (exploded seed). The one month and two month developed seed yield a brown-coloured oil while the exploded seed oil was yellow in colour; both oils were bland in flavour and the physical state ranged from semi – liquid to liquid at room temperature. The titratable acidity values was higher (0.185% lactic acid) in exploded seed. The fatty acid, 11 – Octadecenoic acid were found at levels  14% in all the seed oils; 9,12 – Octadecadienoic acid were also  14% in one month and two months seed oil, while, 9,12 – Octadecadienoic acid were up to 13% in exploded seed oil.

ABSTRACT: This study was conducted to determine the health status of mothers attending antenatal clinic in University of Uyo Teaching Hospital (UUTH) with respect to age and parity. Two research questions and hypotheses were postulated. Cross-sectional research design was adopted. The population consisted of 517 pregnant mothers, who attended antenatal clinic in UUTH.  A sample of 258 pregnant mothers was drawn for the study using systematic random sampling technique. “Mothers’ Health Status Inventory (MHSI)” was used for data collection. The MHSI was validated by three experts. It was subjected to reliability test using Cronbach Alpha. The result yielded a reliability index of .81. Data from 258 completed copies of MHSI were used for analysis. Frequencies and percentages were used to answer research questions, while Chi-square was used to test hypotheses. Results revealed that 36.9% of mothers below 20 years of age had poor health status. They were affected by excessive vomiting (78.6%), fatigue (71.4%), loss of appetite (64.3%), itching (57.1%), headache (57.1%) and heartburn (57.1%). Similarly, 35.9% of mothers with parity 5+ had poor health status. They suffered from fatigue (72.5%), vomiting (62.5%), backache (62.5%), oedema (60.0%), headache (60.0%), and cramps (52.5%).  There were significant differences in the health status of mothers attending antenatal clinic in UUTH with respect to their ages and parity. These findings call for intervention in order to promote the health status of mothers.

ABSTRACT

Artemisinin combination therapies (ACT) have replaced the old drugs (like chloroquine) used as first line treatment for malaria. This current study aimed to investigate the comparative effects of chloroquine (an old drug) and artequin (an ACT drug) on serum biochemical indices in rats. Thirty-six (36) Wistar rats were randomly assigned into 2 batches. Each batch had 3 groups of 6 rats each. Group 1 was control, groups 2 and 3 respectively received artequin (1.6mg/100g bwt) and chloroquine (0.875mg/100g bwt) orally and once daily. Administration lasted for 3 and 7 days for batches 1 and 2 respectively. The biochemical analysis of the serum was carried out using standard methods. Results obtained on both days 3 and 7 showed that serum total protein and globulin concentrations in the artequin group was significantly lower (p<0.05) compared to control. The alkaline phosphatase concentration in the artequin group on day 7 was significantly (p>0.05) higher compared to control. In conclusion, administration of artequin and chloroquine at their recommended doses and duration is relatively safe. Prolonged administration of artequin could predispose to low serum proteins and globulin with accompanied elevations in ALP levels while chloroquine could increase AST level signifying hepatocellular damage.

ABSTRACT: This study is an attempt to model daily confirmed cases of coronavirus in Nigeria. A time plot of the series shows an upward trend with some seasonality. It is tested for unit test and is shown to be non-stationary. Its difference shows evidence of stationarity. The correlogram of the difference shows significant spikes at the partial autocorrelation function at lags 1 and 12 and at its autocorrelation function at lags 1 and 13, with the lag 13 spike surrounded by spikes of comparable lengths in the same direction. This suggests an autoregressive fit of lags 1 and 12 and a moving average fit of lags 1, 13 and 14. A fit of the model shows that only the moving average lags are significant. A more specific SARIMA(0, 1, 1)x(0, 0, 1)13 model is fitted to the series. This shows that the series may be regarded as a SARIMA(0, 1, 1)x(0, 0, 1)13 case.

ABSTRACT

Global trend of urbanization has changed considerably as the development on flood plain is evident in urban settlement. This is the case of Kaduna urban area. Kaduna urban area is divided into almost two equal halves by river Kaduna. The Master plan of the Kaduna designated floodplain along the river to avoid exposing the inhabitant of the area to flood vulnerability. Nevertheless, land use development has since taken over the designated area of the floodplain which is the thrust of the study. The study aims at analyzing the urban land uses components that had encroached into the flood plain with the view of making recommendation for improvement. The study uses GIS tool as a model to determine the spatial extent of encroachment into the floodplains of the River. The study divided the study area into catchment areas for easy assessment. At the end of the analysis, the study established that the rate and nature of urban land use encroachment into the floodplain is progressive in nature. The average encroachment rate into the designated area was established at 49.9Km2 which represents 40.92% of the total land areas designated as flood plain in 1967. Among the land uses that has encroached into the flood plain, residential land use has the highest encroachment level with 85.8% of the area encroached by it while others like industrial, educational and institutional land uses encroached 5.8%, 2.8% and 1.4% into the floodplain respectively. The lowest encroached land use into the area is the commercial, infrastructure and recreational land uses with 0.1%, 0.2% and 1.2% respectively. Based on these established facts, the following recommendations were given; there should be relocation of the inhabitant of the land uses to avoid risk of flood vulnerability; there should be effective policy integration and implementation of all urban management agencies responsible for physical development in Kaduna metropolis to avoid further encroachment into the floodplain; there should be land acquisition of all encroached and un-encroached area of the flood plain by the state government so as to regulate the area; there should be the creation of floodplain Buffer Zone to outline detail profiling of the existing built up area and the existing land use encroachment in the floodplain of the area; and land in safe and accessible locations should be supply to meet the needs of all sectors of the society to avoid further encroachment into the floodplain;
