Studies on the nutrient composition and associated spoilage fungi of different varieties of breadfruit were carried out in the Department of Plant Science and Biotechnology, Rivers State University. Four varieties comprising Artocarpus altilis, A. camansi, A. heterophyllus and Treculia africana were assessed in this study. Proximate analysis revealed that T. africana recorded highest values for lipid (11.87±0.06), fibre (3.27±0.06), carbohydrate (51.17±0.12) and energy (377.1±0.00). However, highest concentrations of moisture and protein were observed for A. altilis and A. heterophyllus respectively. A. camansi recorded highest ash content (3.8±0.00). Vitamins assessed were vitamin A and thiamine. A. altilis recorded highest value of vitamin A (9.2±11.95) while highest concentration of thiamine (1.8±0.00) was observed for A. heterophyllus. Eight fungal organisms viz: Rhizopus spp, Aspergillus Niger, A. flavus, Mucor spp, Penicillium spp, Fusarium spp, Cryptococcus neoformans and Trycophyton rubrium were isolated and associated with breadfruit in this study. Highest percentage incidence (26.7%) was recorded for Rhizopus spp while least incidence of 4.4% was observed for Trycophyton rubrium. In general, A. africana had more proximate and appreciable vitamin parameters than other varieties assessed.

By using an appropriate numerical method to model the impact of interacting rate of virus and uninfected cells, we have found that a bifurcation in the quantification of the impact of the disease condition has occurred between a decreased variation value of β at 99.8% and increased variation value of 105% and also the lower limit of the bifurcation interval to be 0.001188 and the upper limit of the bifurcation interval to be 0.00126 which is a vital intervention information in our bid to mitigate against the Ebola disease condition. The novel results that we have obtained which we have not seen elsewhere are fully presented and discussed quantitatively.

The main aim of this study was to establish the influence of condition of playground on the participation of pre-school children in physical education (PE) activities in Kasarani Sub-county, Nairobi City County, Kenya. Bandura’s Social Learning Theory of (1977) guided the descriptive design study and specifically used the survey method. Out of the 50 targeted pre-schools, 15 (30%) of them and 30 (30%) out of 100 teachers formed the sample size. Questionnaires as well as observation checklists were employed to collect data, and piloting conducted in four randomly selected pre-schools, to determine the soundness of the research instruments. Data was analyzed descriptively and also by use of correlations. Findings show that the playground status of most of the preschools in Kasarani Sub-county of Nairobi was inferior and characterized by poor fencing and presence of unsafe materials. The study findings further revealed that most of the respondents rated the adequacy of playground equipment as medium, especially due to the fact that large equipment were not present in most of the preschools. The researcher’s rating from observations made practically also concurred that the status of the playground equipment was medium, since even in schools where equipment were present, some were not functional while others were in deplorable condition. The study thus concluded that the condition of playgrounds in most preschools in Kasarani was generally poor hence leading to low participation of preschool children in P.E. Despite the fact that inferential results show that there is no significance between the condition of the playground and children’s participation in P.E, the study recommended that playgrounds must be safe because they serve to improve children’ holistic growth, development and learning. Hence the Ministry of Education, preschool proprietors, managers, administrators, teachers, parents and other pre-school stakeholders should be tasked to ensure the playground surfaces are safe for children’s use always, in order to minimize injuries while at the same time increasing participation in physical education activities in the outdoor pre-school environs.

The paper investigated the impact of interest rate on domestic investments and economic growth of Nigeria using time series analysis and annual data from 1980-2016. Using interest rate, inflation rate, money supply and the rate of economic growth as independent variables and domestic investment as dependent variable, the study applied Auto -Regressive Distributed Lag (ARDL) method. This is based on the outcome of ADF unit root tests which revealed that the variables are integrated of I(1) and I(0). The ARDL bounds test result provided evidence of a stronghold long run relationship among the variables. This necessitated the estimation of ARDL short run and long run results. The short run results of the model revealed that MS (-2) is significant but with positive impact of interest rate on domestic, investments and economic growth of Nigeria. The long run results indicated that MS was made significant but with negative impact on Nigeria Domestic Investment. The impacts of INTR, INF, MS, MS (-1) and EGR were positive and negative in both long and short runs. The outcome of the diagnostic tests supported the acceptability of the model results and it was concluded that over the years, the cause of low investment in Nigeria is due to high and fluctuating interest rates. Thus, the formulation and implementation of financial policies that enhance investment-friendly rate of interest is necessary for promoting economic growth in Nigeria.

The research was conducted to ascertain level of awareness and attitude of parents, students and the public towards technical and vocational system of education. A sample of 400 students from various secondary schools, 400 parents in the community and 400 private/public employees completed a questionnaire that was designed to validate the study. Percentage scores were used to answer the research questions. Results show that students, parents have exhibits negative attitude towards acquiring skills/knowledge from technical colleges. Only 22.5, 35 % of the students, parents preferred acquiring awards from technical colleges; 77.5, 65 % students, parents preferred their wards to acquire knowledge from university system of education. It was observed that parents with low economical, educational status in the society tend to encourage their wards to undergo Technical and Vocational system of Education. While, students from poor economic background belief that university system of education is meant for the wealthy family. On the basis of these findings, proactive recommendations were made to improve attitudinal change towards technical and vocational system of education.

The study investigated the cardiocurative effect of the seed of Tetracarpidium Conophorum extract on wistar rats with doxorubicin-induced myocardial infarction. Herbal drugs are used widely even when their biologically active compounds are unknown, probably because of their effectiveness, lesser side effects and affordability. The result of this study will provide harmless and affordable remedy for cardiotoxicity and other oxidative stress induced diseases. Twenty adult wistar rats (140 – 330g) of both sexes were divided into five experimental groups (A, B, C, D, and E). Each group had four rats. Group A, B, C, D, and E represented groups treated with food only, doxorubicin only, (doxorubicin + 6% walnut of feed), (doxorubicin + 12% walnut of feed) and (doxorubicin + Enalapril) respectively. Cardiotoxicity was induced by the cumulative administration of 15mg/kg doxorubicin intraperitoneally during the first alternate seven days (1st, 3rd, 5th, and 7th day). After the treatment period of forty-two days, blood samples and hearts were collected for biochemical and histopathological studies respectively. Serum enzyme and lipid profile were checked. There was significant increase (p < 0.05) in aspartate transaminase, alanine transaminase, lactate dehydrogenase, creatine kinase, total cholesterol, triglycerides, low-density lipoprotein and very low-density lipoprotein with significant decrease (p < 0.05) in high-density lipoprotein in the group induced with doxorubicin without additional treatment when compared with the Tetracarpidium Conophorum and Enalapril treated groups. This observation was supported by histopathological report. The repeated administration of doxorubicincaused toxic damage to the myocardium. But treatment with the Tetracarpidium Conophorum significantly restored (p < 0.05) the myocardium from the toxic damage. Treatment with Enalapril produced the best abatement, followed by the 12% walnut of the feed intake.

The demand for work-life balance by employees have increased in organizations. Therefore, work-life balance must be effectively managed by organization so as to have competitive advantage over their competitors due to fast pace of economic development. The study examined the factors that influence work-life balance in government owned organization in Nigeria. A conceptual review of literature was done. Information were gathered from textbooks, articles, journals conference proceedings. The result from the proposition revealed that there is relationship between work-life balance and employee performance. The study therefore concluded that work-life balance factors such as flexible-work arrangement, employee wellness programs and family responsibility are important tools that could be adopted by organization in order to ensure that their staffs are satisfied. The study therefore concluded that work-life balance is beneficial for employee performance and therefore recommends continual renewal of work-life balance policy which will help in improving employee performance and will also have positive effect on organizational productivity.

Studies on the mineral, phytochemical and bacterial Flora of four varieties of breadfruit were carried out in the Department of Plant Science and Biotechnology, Rivers State University. Mineral investigation revealed the presence of calcium, iron, magnesium, phosphorus, potassium and sodium in all tested varieties. A. altilis recorded highest contents of iron, phosphorus, potassium and sodium while highest contents of calcium (7.4±0.00) andmagnesium (6.0±0.00) were seen for A. camansi and T. africana respectively. Phytochemical screening showed that A.altilis had highest values (1.5±0.00, 2.6±0.00, 4.7±0.00 and 5.0±00) for oxalate, tannin, carotenoid and polyphenol respectively. T. africana recorded highest contents of phytate and lignan while highest concentrations of saponin and flavonoid were observed for A. camansi. Seven bacterial isolates were found to be associated with the four varieties of breadfruit and they include Proteus spp, Staphylococcus aureus, Pseudomonas spp, Bacillus spp, Paenibacilliumspp, Streptococcus spp and Escherichia coli. Highest incidence of occurrence was observed for Bacillus spp while Paenibacilliumspp recorded least percentage incidence of 4.4. Generally, A. altilis contains more mineral and phytochemical contents than every other breadfruit variety investigated.

The study examined the impact of mathematical terminologies on students understanding of mathematics in senior secondary schools in Yobe State. A descriptive survey design was adopted for the study. The target population comprising all teachers of mathematics in the selected schools and some randomly selected students within the schools. The research questions were answered using descriptive statistics (mean and standard deviation). The population of the study was 3,522 participants comprising 48 principals and 3,474 Teachers of senior secondary schools within the three education zones of Yobe State. Based on the result there is a barrier between the students and the teachers in terms of the application of mathematical terminologies. Also the result shows that setting examination, question using mathematical terminologies is not a problem and not be the cause of mass failure in schools the study encourages teachers to increase the use of mathematical terms in setting examination questions. Another result shows that majority of the terminologies used are subtraction, multiplication and addition, complicating terminologies such as COSINE, TANGENT and SINE are commonly avoided and this is an indication that even the teachers are not well equipped with the knowledge of the terms making application vague. The result of the analysis contradicts the well-known beliefs that, the teachers are not giving much attention to the concepts of terminology in teaching and learning mathematics. The result from attempt to improve the use of the terms in schools shows that there is a need to organize workshop and conferences for teachers in order to equip them with the use of mathematical terminologies in teaching and learning process. Make a subject called mathematical terminologies at lower level of education and introduce to all schools, there should be special teachers for training students on the use of mathematical terminologies

This study examined the influence of students’ attitudes toward mathematics on motivation to learn mathematics among high school students in Laikipia County, Kenya. The study was guided by Keller’s ARCS model of motivation. Descriptive survey research design was used in the study. The target population consisted of all 8357 Form Four students in Laikipia County. Simple random sampling was employed to select the sample schools, sample classes, and respondents. A sample of 392 students (i.e., 216 males and 176 females) was selected for the study using Krejcie and Morgan’s table of sample sizes. A self- administered questionnaire was used for data collection. Cronbach’s alpha was used to determine the reliability of research instruments. Motivation to learn (MTL) had a reliability coefficient of 0.95, while attitude toward mathematics (ATM) had a coefficient of 0.97. Data was analyzed using t-test and simple regression analysis. The results revealed that: (i) there is a significant gender difference in attitudes towards mathematics favoring male students, and (ii) students’ attitudes had a significant influence on students’ motivation to learn mathematics. The study concludes that: (i) mathematics teachers should put more effort to ensure that all students regardless of gender have similar attitudes toward mathematics and (ii) mathematics teachers should avoid negative attitude influence practices and also apply appropriate motivational techniques to improve students’ motivation toward mathematics.

This study aimed to determine the physicochemical parameters in some selected borehole and dug well water within Fika local government area, Yobe State. Ten (10) sample were collected, two (3) Borehole water and seven (7) Hand dug - well water from different locations and were cleaned in plastic container sealed and transported immediately to the laboratory for analysis. Heavy metals were analyzed using AAS (Atomic absorption spectrophotometer). From the experimental result it shows that the concentration of Cu, Pb, Zn, Cr and Fe in the samples all conformed to the requirement of WHO, NSDWQ and SON standards. But the concentration of cadmium (Cd) in all the samples exceeds the limit. The physical parameters such as pH, conductivity were conformed to be within the standard limit except turbidity which exceeds the limit in sample (DWC, DWD, DWE, BHF, DWH and DWJ). It is concluded that all the Hand dug well water samples are not absolutely good for drinking as stipulated by WHO. It is also recommended that the sources of borehole water required frequent treatment to meet the standard for portable drinking water. Therefore, people should use the Borehole water often than the hand - dug well water as regard to areas without doubt.

Fuzzy reasoning is based on fuzzy sets theory, where membership of a set by an entity is incremental instead of either a member or not a member. Fuzzy logic provides the control interval of real numbers between zero (False) and one (True) to establish logic as the base for inference rules. The fuzzed variant of the design philosophy case of this research rule of inference helps computers to make decisions using fuzzy reasoning instead of precision. This study adopts the use of Fuzzy Max – Min method, Minimization of regret method (FMMR) and ordered weighted averaging (OWA) in decision making problem under uncertainty.

The research identifies the sources and characterizes the concentrations of n-alkanes and polycyclic aromatic hydrocarbons (PAHs) in sediment and Littorina Littorea from Okujagu River. Samples were evaluatedutilizing n-alkanes, 14 PAHs and Gas chromatography Mass spectrometer (GC-MS) ranging from C17 to C32 were identified and quantified. Total PAH and n-alkane dosage for both samples ranged from 2.38 to 2.48mg/kg and 0.36 to 3.127mg/kg respectively. The sources were examinedutilizing PAH diagnostic ratios and n-alkane indexes. n-alkanes were characterized by carbon preference index (CPI), n-alkane proxy (Paq), Carbon maximum (Cmax), and the ratio of long chain hydrocarbons to short chain hydrocarbons (LHC/SHC). PAH diagnostic ratios such as Phenanthrene to Anthracene (Ph/An), Fluoranthene to Pyrene (Fl/Py), Ant/(Ant+Ph), Fl/(Fl+Py) and the ratio of lower molecular weight (LMW) PAHs to higher molecular weight (HMW) PAHs (LMW/HMW) were calculated to evaluate both petrogenic and pyrogenic (pyrolytic) PAHs. From the results, the diagnostic ratio of (Fl/Py) for sediment was 40 (>1) indicating PAHs origin from pyrolytic source while Fl/Py ratio of the Littorina Littorea sample was 0.25(<1) indicating petrogenic source. The (Ph/An) ratio for sediment and Littorina Littorea were 3.5(<10) and 0.008(<1) respectively implying that the PAHs are source from combustion processes (pyrolytic). Also, the ratio of Ant/(Ant+Ph) was 0.22 (>0.1) for sediment and 0.99 (>0.1) for Litorina Littorea indicating PAHs origin from pyrogenic(pyrolytic) sources. While the ratio of Fl/(Fl+Py) was 0.98 (>0.4) for sediment suggesting PAH origin from pyrogenic(pyrolytic) source and 0.2 (<0.4) for Littorina Littorea indicating PAHs origin from petrogenic sources. The ratio of (LMW/HMW) PAHs was calculated to be 2.42 (>1) for sediment and 24.608 (>1) for Littorina Littorea indicating PAHs origin from petrogenic sources. According to the diagnostic ratios used in this study, the PAHs in the sediment and Littorina Littorea samples originate from both pyrolytic and petrogenic sources. The study recommends that the disposal of waste, effluent discharges from industries and chemical release through agricultural activities into the marine ecosystem should be regulated as to control the contaminants in the system.
