The Career Prospects of Tourism in Nigeria

The increasing need for leisure travel and the overwhelming tourism development in Nigeria has necessitated high level of human resource management in order to meet up with challenges facing the tourism industry. Of a truth, many tourism students graduates without clear understanding of the magnitude of career prospects awaiting them; while those still undergoing the programme are clouded with doubts about what the future holds for them. This paper therefore seeks to address this problem. It examines the various programmes obtainable in Nigerian institutions of learning and the career prospects of tourism students in Nigeria

The Effects of Eggshell Ash on Strength Properties of Cement-stabilized Lateritic

Eggshell ash obtained by incinerating Fowls’ eggshells to ash has been established to be a good accelerator for cement-bound materials and this would be useful for road construction work at the peak of rainy seasons for reducing setting time of stabilized road pavements. However this should be achieved not at the expense of other vital properties of the stabilized matrix. This is part of the effort in adding value to agricultural materials which probably cause disposal problems. Thus this study aimed at determining the effect of eggshell ash on the strength properties of cement-stabilized lateritic soil. The lateritic soil was classified to be A-6(2) in AASHTO rating system and reddish-brown clayey sand (SC) in the Unified Classification System. Constant cement contents of 6% and 8% were added to the lateritic soil with variations in eggshell ash content of 0% to 10% at 2% intervals. All proportions of cement and eggshell ash contents were measured in percentages by weight of the dry soil. The Compaction test, California Bearing Ratio test, Unconfined Compressive Strength test and Durability test were carried out on the soil-cement eggshell ash mixtures. The increase in eggshell ash content increased the Optimum Moisture Content but reduced the Maximum Dry Density of the soil-cement eggshell ash mixtures. Also the increase in eggshell ash content considerably increased the strength properties of the soil-cement eggshell ash mixtures up to 35% in the average but fell short of the strength requirements except the durability requirement was satisfied

Determinants of Volume of POME Generation in Palm Oil Mills for Planning Wastewater Recovery in Biogas Energy Development

Wastewater volume is a necessary prerequisite for planning transformation to valuable resource and averting environmental degradation. This study investigated the dynamics of POME volume generation in palm oil mills in relation to types of fresh fruit bunches (FFBs), seasons, milling scales and volume of crude palm oil (CPO) produced in ADAPALMS and catchment communities, Ohaji/Egbema LGA, Imo State. The eight catchment communities of ADAPALMS were categorised into three strata in relation to the number of small-scale mills in each community (1-5mills, 6-10mills, and 11-15mills). In each stratum, a community was randomly sampled. A total of nine small-scale mills were sampled from the three sampled communities (Ohoba, Amafor and Etekwuru) in proportion to the average number of mills in each stratum. The lone medium and large scale mill (ADAPLAMS) in the study area represented the other scales of milling. For small and medium scale mills, the volume of POME generated was measured from the dimensions of the vessels where POME was stored, while that of large scale mill was obtained from industrial records. Data was analysed using multiple linear regression of SPSS. The volume of POME generated is significantly related to milling scales and volume of CPO produced (p< 0.01); R2=0.788. Within small scale mills, the volume of POME is significantly related to types of FFBs (p< 0.01), different small milling scales (p< 0.05), and volume of CPO produced (p< 0.01); R2=0.762. Thus, these independent variables are the principal determinants of POME volume generation in the area. The result has implication on the necessity of predictive models in managing the dynamics of POME volumes for efficient recovery and transformation of the wastewater to bioenergy

Sources and Functionality of Rural Water Supply in Communities from three Senatorial Zones of Imo State, Nigeria

Sustainability of domestic water access in communities is essential for good health, society’s dignity and progress. This study investigated the sources and functionality of rural water supply in nine communities of three local government area (LGA) in three senatorial zones of Imo State, Nigeria using structured questionnaires. The questionnaires were administered on 100 women in each community. Data obtained were analysed using multivariate analysis of variance (MANOVA) to reveal the frequency of using the various sources of rural water supply, and Wilcoxon’s test for matched pairs to reveal the functionality status of the most frequently used water source. The findings indicate the importance of borehole water facilities in these rural communities and the necessity for intervention programs to strengthen their functionality in tandem with the State’s aspirations in achieving sustainable development goals

Comparative evaluation of partial replacement of soybean meal with raw and oven-dried cassia tora seedmeal on the performance of broiler chickens

This study was conducted to comparatively evaluate partial replacement of soybean meal with raw and oven-dried Cassia tora seed meal (CTSM) on the performance of broiler chickens. An eight-week feeding trial involving two hundred and eighty eight (288), day-old chicks purchased from a reputable chick dealer in Uyo Metropolis was used for the study. Four experimental diets each of raw and oven-dried CTSM was formulated such that diets 1, 2, 3, and 4 contained 0%, 5%, 10%, and 15% CTSM respectively. The birds were randomly assigned to the eight dietary treatments of 36 birds each. A treatment was replicated thrice, with 12 birds per replicate in a completely randomized design (CRD). The parameters evaluated were body weight gain, feed intake, feed conversion ratio and blood parameters. Data obtained were subjected to analysis of variance (ANOVA), using SPSS version 20. The results showed that the dietary treatments significantly influenced the growth indices. Weight gain was highest at 10% inclusion of raw CTSM and also at 15% inclusion of oven-dried CTSM. Feed intake response was highest at 10% inclusion of raw CTSM and 15% inclusion of oven-dried CTSM while feed conversion ratio (FCR) was greatly improved at these inclusion levels. The inclusion of raw and oven-dried CTSM at 10% and 15% respectively did not adversely affect carcass qualities and organs. Inclusion of raw CTSM up to 15% adversely affected carcass quality and haematological parameters. Also, haematological parameters of broiler chicken were best at 10% and 15% inclusion of raw and oven-dried CTSM respectively. When all parameters were considered, performance of broiler chickens was best at 10% inclusion of raw CTSM and 15% inclusion of oven-dried CTSM. It is therefore recommended that raw CTSM can only be incorporated into the diets of broiler chickens up to 10% without any detrimental effect. But oven-dried CTSM can be incorporated up to 15% without any detrimental effect. &nbsp

A Review of Environmental Implications of Dredging Activities

Dredging is a global anthropogenic excavation activity of removing sediments from water bodies and depositing it elsewhere. It is a mixed blessing as it has both beneficial and adverse impacts. This paper is on a review of environmental implications of dredging. The objective of the paper is to review previous works by researchers on the environmental consequences of dredging. The method used is a review of academic/journal articles, internet materials, conference / workshop papers, textbooks, bulletins and publicly available materials on dredging activities. The results of the study revealed that previous authors whose works were reviewed have a convergent view that apart from the beneficial impacts of dredging (e.g. keeping waterways navigable, flood and storm protection and provision of materials for road construction and building), it has lots of adverse environmental impacts, including environmental pollution, erosion, widespread hydrological changes, reduction in the population of aquatic lives like destruction of fish spawning grounds and benthic organisms and resuspension of particulate matter column that has elevated levels of lead, copper, zinc and nickel in Phytoplankton. Recommendations of the study include: (1) establishment of environmental legislations and regulations for dredging operation; (2) use of green technology in dredging activities to minimize suspension of sediments and contamination/pollution of dredging environments; and (3) creation of awareness among dredging contractors, regulators and marine communities where dredging take place on the economic and ecological values of the marine ecosystems that are usually very sensitive, fragile and productive

The Relationship between Selected Anthropometric Indices and Cardiorespiratory Fitness in Apparently Healthy Young Adults in a Nigerian Community

Background and Aim: Cardiorespiratory fitness (CRF) is a useful tool for establishment of baseline fitness status and monitoring of physical activity level. Therefore, it may by extension serve as health risk index. However, studies that have determined the correlation between anthropometric indices and CRF in apparently healthy young adults is difficult to find in other to preempt preventive actions before pathology develops. Materials and Methods: Using a descriptive correlational research design, 325 participants (160 males, 165 females) with mean age of 21.87±2.41 years were sampled. Tape measure, stop watch, metronome, sphygmomanometer, stethoscope, height meter, bathroom weighing scale, modified Borg’s exertion scale and step benches were used to obtain the blood pressure, heart rate, respiratory rate, rate of perceived exertion, height, weight, waist circumference and cardiorespiratory fitness was estimated using the mean heart rate responses of the participants. The data was summarized using frequency count, percentages, range, mean, standard deviation, Independent t-test and Pearson’s Product Moment Correlation at alpha level of 0.05. Results: CRF significantly correlated with post-test systolic blood pressure (p= 0.004), post-test diastolic blood pressure (p= 0.010) and resting heart rate (p= <0.0001) but not with BMI (p= 0.133), waist circumference (p= 0.098), pre-test systolic blood pressure (p= 0.155), pre-test diastolic blood pressure (p= 0.121), resting respiratory rate (p= 0.631), and respiratory rate recovery (p= 0.478). Conclusion: CRF can be used as an index to quantify in apparently healthy participants, level of cardiovascular and respiratory related disease risks. It is necessary to emphasize the importance of physical activity in order to improve one’s cardiorespiratory fitness and minimize the risk of cardiorespiratory associated diseases

HYPOGLYCAEMIC AND HAEMATINIC PROPERTIES OF ETHANOL LEAF EXTRACT OF ARTOCARPUS HETEROPHYLLUS IN ALLOXAN INDUCED DIABETIC RATS.

Background: Anaemia is known to be associated with diabetes; moreover, with the increasing cases of diabetes there is need for the use of more affordable alternative herbal medicines for the treatment of diabetes and anaemia. The aim of this work was to evaluate the hypoglycaemic and haematinic properties of Artocarpus heteropyllus on diabetic rats. Materials and Methods: Ethanol leaf extract of Artocarpus heteropyllus was screened for phytochemicals and its acute toxicity was tested on mice. Induction of diabetes was done at a dose of 150 mg/kg body weight (b.w) (with exception of the control group). The extract was administered to rats for a period of 7 days at 100, 300 and 500 mg/kg b.w, respectively, following induction. Blood samples of rats were tested for fasting blood sugar (FBS), packed cell volume (PCV), white blood cell (WBC), red blood cell (RBC), haemoglobin, neutrophil lymphocyte and eosinophil counts. Results: The ethanol leaf extract of A. heterophyllus showed no mortality up to a dose of 5000 mg/kg b.w. Administration of the extract to diabetic rats resulted in a decrease in the FBS of diabetic rat, and significant increases (p< 0.05) in RBC, PCV, WBC and haemoglobin levels. Conclusion: The ethanol leaf extract of A. heterophyllus increased the haematological indices of diabetic rats. Our findings support the use of this plant as an herbal alternative in the treatment of diabetes and anaemia associated diabetes
