MENERALS REQUIREMENT OF ATHLETES IN HOT AND HUMID ENVIRONMENT
OGAR, EMMANUEL EKAWU & PROF. E.A. GUNEN (COURSE LECTURER)
Department of Human Kinetics and Health Education, Faculty of Education, Ahmadu Bello University, Zaria, Kaduna
Competition in a hot or humid environment is not always conducive for optimal sports performance as both dehydration and hyperthermia greatly affect the mental and physical performance of athletes. In addition, the ability to train in heat is also impaired if the nutritional requirements are lacking or inadequate in the right proportion. During prolonged exercise in a hot environment, an excess of 1 liter of body fluid per hour can be lost. Fluid intake strategies should be undertaken and should be of paramount concern to the athletes and coaches if the athlete has to perform more than one training or competition sessions in a single day. Fluid strategies, including hydration well prior to the exercise or competition, drinking as much as is comfortable and practical during the exercise or competition session, and rehydrating aggressively afterwards in preparation for the subsequent exercise, are needed to ensure an adequate water intake to prevent chronic dehydration or muscle cramps during competition in hot conditions as the body does not adapt to dehydration. Rapid recovery of fluid losses after an exercise is assisted by the replacement of some of the electrolytes (nutrients) losses. Carbohydrate is the main fuel used by the muscle during training and competition and its requirement for exercise in hot conditions is further increased due to the shift in substrate utilization towards carbohydrate oxidation. Daily food intake should focus on replacing glycogen stored in the muscles after active exercise. Competition diet strategies such as enhancing carbohydrate availability (carbohydrate loading) prior to endurance competition, pre-event carbohydrate intake, intake of sports drinks in events lasting longer than 45-60 minutes should be undertaken in hot conditions and practiced regularly during training to get acclimatized. Carbohydrate ingestion may not enhance performance for all events undertaken in hot environment, however, there is no disadvantage of consuming sports beverages (snacks) containing the appropriate carbohydrates and electrolytes during training and competition. There is also no good evidence to suggest that specific supplementation is necessary or will improve performance in sports activities undertaken in a hot environment. The maintenance of fluid balance is the key issue for performance of the athletes. In a hot environment, significant dehydration is inevitable during exercise activities and poses a challenge to both the health and performance of the athlete.

AMAO D. ONAOLAPO PhD, PROF. SALMAN F. MEDINAT & BAKARE A. BASIRAT PhD
Department of Science Education University of Ilorin, Ilorin.
Further Mathematics is a useful and dynamic subset of Mathematics particularly to students aspiring to study Engineering, Mathematics, Technology and Science related courses. A few large numbers of students do not offer and register for the subject probably because they believe that it is more abstract and difficult than general Mathematics. The objectives of this study were to investigate: (i) teachers’ and students’ beliefs about the nature of Further Mathematics, (ii) whether any difference exists between teachers’ and students’ beliefs about the nature of Further Mathematics. The study was a descriptive research with the use of survey method. The population comprised all students offering Further Mathematics and their teachers in the selected secondary schools in North Central, Nigeria. Purposive sampling technique was used to select 30 out of 43 secondary schools offering Further Mathematics in the Zone. The sample consisted 350 (220 private and 130 public) out of 570 students, while 50 (29 private and 21public) out of 79 Mathematics teachers were randomly selected. The researcher-designed instruments used for the study were “Students’ Beliefs about the nature of Further Mathematics Questionnaire” (IOSBANFMQ) and “Teachers’ Beliefs about the Nature of Further Mathematics Questionnaire (IOTBANFMQ)”. The instrument yielded reliability value of 0.87 using Pearson Product Moment Correlation formula. The research questions were answered using percentage, mean, standard deviation and charts, while Multivariate statistical analysis was used to test the null hypotheses. Findings of the study showed that: (1) teachers’ and students’ beliefs about the nature of Further Mathematics have the overall aggregate mean scores of 2.91and 2.95 respectively with benchmark of 2.50; (2) with respect to ethics and aesthetic, process, social and cultural nature of Further Mathematics, there exist a significant difference in the beliefs of teachers and students in favour of students, F(1, 398)=7.384, p<0.05; Based on the findings, it was affirmed that teachers and students believe that Further Mathematics requires a lot of creativities; enhances logical reasoning; entails endurance and provides foundation for applied science. Its implication is that teachers and students could change; and modify their beliefs about the nature of Further Mathematics. It was therefore recommended that Further Mathematics teachers should reflect their beliefs in teaching strategies to enhance students’ positive attitude towards studying Further Mathematics.

A non linear differential equation model is proposed to examine the Changes in the Human Population of Orji In Owerri North Local Government Area of Imo State Nigeria. The dynamical system is used to explain the changes in Human population profile whenever there is percentage birth rate increase over death rate and vice versa, whereas the impact of Fertility (birth and death) rate which plays a key role in a demographic study of any country was observed. The method of computational modelling otherwise called numerical simulation is adopted in this study. Detailed deterministic quantifications of the effect of varying the fertility rates on the growth of populations Orji communities is also investigated. Results show that changes in human population can be influenced by variation of fertility rate. Decreasing fertility rates produced an increase on the population growth of Orji populations. Also, an increase in fertility rates produces depletion (decrease) on the population growth of Orji populations. Thereby creating more opportunity of economic growth which may not be automatic, important investments in education and health sector are needed for actualization of demographic dividend in Orji , Owerri North Local Government Area , Imo State , Nigeria.

Having studied the effects of varying the intrinsic growth rates together on the type of stability in the context of two competing technologies to obtain a dominant occurrence of stability with a zero bifurcation, we have applied the similar method of a Matlab Algorithm to obtain a total of six (6) instances of degenerate steady state solutions and forty eight (48) scenarios of valid stability. The bifurcation from a stable steady state solution to a degenerate steady state has occurred for the following pairs of the intra – competition coefficient (0.00240, 0.00360) and (0.00120, 0.00018). Next, we have found another bifurcation from a degenerate steady state solution to a stable steady state solution between examples 7 and 8 as displayed on Table 1; the novel results which we have found that we have not seen elsewhere are presented and discussed.

The electrical properties of soils are the parameters of the natural and artificial field in soil influenced by the distribution of mobile electrical charges mostly inorganic ions in the soil. Identifying low resistivity earth materials and their potentials becomes imperative. The aim of this study is to carry out the soil resistivity survey of the study area. The method used in sample collection is the surface scraping and digging to a depth of about 20 cm at random where each location coordinates is taken using a Global Positioning System (GPS). The samples are stored in plastic containers and taken for laboratory ex-situ measurements. A conductivity meter is used to determine each sample’s conductivity where the resistivity of each sample is calculated from the reciprocal of the conductivity. The result is digitized and a contour map of the study area is plotted using Surfer software. The map shows the delineation of the resistivity variation in the study area. The spatial variations of resistivity in the study area are found to be between 5.5 x 103 Ω-cm to 1.6 x 104 Ω-cm.

Information and communication technologies (ICT) have the potential to improve all aspects of our social, economic and cultural life. The introduction of ICT in universities as institutions of higher education is clearly changing the way in which education is conducted. But, as much as important its introduction is, the more important is the acceptance of new technologies. For that purpose, we shall use a unified theory of acceptance and use of technology (UTAUT) which will explain the user’s intention to apply information systems and subsequently to monitor the behavior of their usage. This paper describes the UTAUT model and the factors that affect it, and its modification over time. Furthermore, examples are given for the application of UTAUT in different environments. Lastly, in the conclusion we note why the uptake of ICT is mandatory and what should be undertaken in order to accept a new technology.

The magnitude of self-similarity on a wireless network determines the QoS available to the end users, it becomes very much necessary to have an insight into the network traffic self-similarity characteristics and its measurement. This research took a look at the degree of Transport Control Protocol (TCP) self-similarity on a wireless local area network and its measurement. A total of 1,204,215 TCP traffic volumes were captured, out of which 178,563, 176,127, 163,556, 225,594 231,728, and 228,647 traffic volumes were captured on 1th, 5th, 10th, 13th, 18th, and 21st of February 2018 respectively. It was observed that the ACF takes longer range to decay in lag of (-200,000 to 200,000) on 13th, 18th and 21st February, 2018 with the rest having the lag of (-150,000 to 150,000). The research confirmed the presence of LRD traffic by applying autocorrelation test on the captured live traffic and it showed an autocorrelation function that decays hyperbolically. Four Hurst estimators were employed so as to complement each other’s shortfall. An average daily Hurst parameter of 0.748, depicting a persistent characteristics. The research recommends the use of neuro-fuzzy principles to x-ray the cause of self-similarity on a wireless network.

Department of Mathematics and Statistics, Federal Polytechnic, Nasarawa, Nigeria
This study developed some specific population growth models and subjected them to accuracy test in order to determine the most appropriate model for the prognosis of Nasarawa State population. The study employed method of differential equation, exponential, geometric and hyperbolic functions as governing equations. Available census data of 1991 and 2006, Mean Absolute Error (MAPE) and Root Mean Square Error (RMSE) were used to obtain the growth rate and compared the three developed models for the population prognosis accuracy. The result of the analysis shows that exponential growth model with MAPE and RMSE values of 0.51% and 13.75 respectively is the most accurate and closely followed by geometric growth model with values 0.56% and 14.87 respectively. The study concludes that exponential growth model is the best for the prognosis of Nasarawa State population growth with approximate growth rate of 2.9% per annum, the projected population of the state will be 3,757,536 million by the year 2030. Hence, it is recommended that Nasarawa state government should institute developmental programmes, policies and work towards industrialization of the state to effectively improve its absorptive capacity development through the population size increase.

Salads are sources of vitamins, minerals, Proteins and relevant nutritional components for proper functioning of the human body. However ready to eat foods like vegetable salad are a major potential sources of entropathogenic and food borne illness.This study attempts to look at the microbiological quality of street vended salad from various sources around Bida and Minna in Niger state in relation to public health concerns.Ten samples of salad obtained from Bida/Minna were weighed and transferred into sterile polythene bags and taken to the lab for analysis. The Total plate count was determined and it revealed a high bacterial count which ranged from 2.13 x 103 to 9.7 x 1010cfu/g in Bida while it was 2.06 x 103 to 8.6 x 1010 in Minna. Coliform count (cfu/g) ranged from 1.3 x 103 to 2.6 x 105 while yeast ranged from 1.0 x 103 to 1.8 x 103 in Bida. However the total viable count (cfu/g) of bacteria in Minna ranged from 2.06 x 103 to 8.6 x 1010 (cfu/g), coliform count had 1.2 x 103 to 4.2 x 103 (cfu/g) and the yeast and mold ranged from 1.2 x 103 to 4.0 x 103. There was a high indication of contamination. The standard microbiological procedures and techniques were used to enumerate, isolate, identify and characterize the different micro-organisms associated with the food assessed. Organisms isolated were Pseudomonas Spp, Bacillus Spp, Staphylococcus aureus, Escherichia Coli, AspergillusSp, Rhizopus Sp. The presence of these isolated pathogens in the salad calls for strict food safety regulation and close supervison of street vended salad by relevant authorities to enhance food safety eg, primary health care sector.

Gone are the days when initial cost of an asset is used as criteria for purchase. Recently the tide has changed to the lowest life cycle cost. To achieve this component costs of asset are identified and analyzed. The aim of this paper is to examine the fuel consumption component costs of four different brands of domestic generators for four years with a view to identifying the variability of the fuel consumption of the different brands and the variability from year to year. This was achieved by using the Randomization Block Model. The study revealed that significant difference occurs from brand to brand of the generators. It was also noted that as the operating life increases, fuel consumption increases. Since fueling (Energy) cost is a sensitive factor in the life cycle cost analysis, low fuel consumption may yield lowest LCC. Also, including fuel economy, emission and noise control in the design could make domestic generator more environmentally friendly.

Free-piston linear generator (FPLG) engine is a novel type of engine conversion device which can generate electrical energy. It exhibits advantages of simple structure, less friction, high thermal efficiency, and operational flexibilities. This paper presents the performance characteristics of a spark ignition (SI) direct injection (DI) FPLG engine fuelled using compressed natural gas. The engine was set to run at stoichiometric ratio, 42 mm BTDC injection position and 4 mm BTDC ignition position. The data collected were processed with a macro designed with Microsoft Excel for data processing. The results of the tests revealed that the combustion and mechanical efficiencies of the FPLG engine can attain 45% and 36% respectively with the peak power output of 547 W when the engine was operated at a frequency of 20.33 Hz and air intake pressure of 8 bar. 31.64 bar and 7.61 bar are the peak in-cylinder pressure and indicated mean effective pressure (IMEP) developed respectively for the bounce to attain a pressure of 14.08 bar. Though the electrical power output is low but with further study and improvement on the linear generator assembly, this technology could be used to achieve our energy sustainable goals.

Throughout the course of history, disease outbreaks have ravage humanity sometimes changing the course of history. All sector of the economic will be crumbled, the fear of what next always griped every one and at times, it seems the end of entire civilizations has come. COVID-19 is an acronym of ‘corona virus’ that started in Wuhan, China in December 2019 is one of such plagues. COVID-19 pandemic sweeps across the world putting all aspect of humanity on hold. In many part of the world, the agriculture industry was labeled as critical, allowing business to continue to operate as usual despite current and potential restrictions enacted to stop the spread of the virus. This made every step along the agriculture industry supply chains stepping up to keep employees and consumers safe while still providing vital equipment, services, commodities feed and food. Government in most countries took proactive steps to combat the situation. For instance Nigerian government promised to finance up to 1.6 million people on agriculture this year and different NGOs and individual are also in support, but the restrictions on movement of people and moving raw materials across closed borders or having enough healthy workers to keep the industries operational limit the success. The aim of this write up is therefore, to sensitize the youth to explore some opportunities in agriculture amidst this pandemic to combat the situation both now and in the near future.
