ABSTRACT:

In tropical developing countries where the supply of minerals and protein from animal source is inadequate to meet the rapid population growth, intense research efforts are currently directed towards identification and evaluation of food grains which normally have considerable high protein and mineral content.  The major objective of this research study is to investigate the mineral and amino acid composition and storage condition of breakfast cereal made from sorghum, soybean, Bambara nut and groundnut with a view to increase the nutrients content. Using standardized method, ten samples were formulated by mixing the flours in ratio of (Sorghum flour and 5% of malted sorghum flour) with graded levels of bambara nut flour (80:20, 70:30, 60:40); soybean flour (80:20, 70:30, 60:40) and defatted groundnut flour (80:20, 70:30, 60:40). The formulated flours were subjected to mineral and amino acid determination, microbial analyses, rancidity test and consumer acceptability. The results revealed that mineral composition of the formulated breakfast cereals showed that significant differences (p<0.05) exist between the samples in almost all the parameters studied. The calcium content of the products ranged from 124.54 to 411.36 mg/100g, with sample A (100% MSF+SF) having the lowest value and sample I (60% MSF+SF and 40% SBF) had the highest value. The iron content of the products ranged from 1.23 to 12.46 mg/100g. The magnesium content of the products ranged from 62.35 to 124.54 mg/100g, with sample A (100% MSF+SF) having the lowest value and sample I (60% MSF+SF and 40% SBF) had the highest value. The magnesium content of the products ranged from 62.35 to 124.54 mg/100g, with sample A (100% MSF+SF) having the lowest value and sample I (60% MSF+SF and 40% SBF) had the highest value. The phosphorus content of the products ranged from 84.54 to 365.65 mg/100g, with sample A (100% MSF+SF) having the lowest value and sample I (60% MSF+SF and 40% SBF) had the highest value. There were significant differences (p<0.05) in the amino acid profiles of the developed breakfast cereals. The values increased with the increase in the level of the Bambara nut, soybean and defatted groundnut substitutions. The results reveal that the samples contained varying amounts of both essential and non-essential amino acids. The microbial examination of the products revealed different values for total bacteria count (TBC), total coliform count (TCC), and total fungi count (TFC). The TBC ranged from 3.85 x 105 to 6.06 x 105 cfu/ml, while the TCC ranged between 1.50 x 105 to 3.36 x 105 cfu/ml and the TFC ranged from 4.98 x 105 to 9.77 x 105. The peroxide value (PV) of freshly made samples had a mean value of 5.51 meq/kg, and the maximum PV that most of the samples attained during their course of storage was 6.90 meq/kg. The time when the samples exhibited the maximum PV. varied for each sample depending on the temperature as well as the storage condition. The data obtained from the study were analyzed using ANOVA while the means were separated by Duncan multiple range test. Sample F recorded superior score for appearance and aroma but textural characteristic comparable to sample D

ABSTRACT:

The purpose of this study was to examine the running performance and aerobic endurance following high-intensity continuous running (HICR) of short exercise duration in a moderately trained leisure runner. In this case study, a 42-yr-old moderately trained male leisure runner, with a pre-training relative maximal oxygen consumption (VO2max) of 55.8 mL·kg-1·min-1, performed 10 min of HICR (90% to 95% of maximal heart rate (HRmax) 3 times·wk-1, for 5 weeks. Following the training intervention period, time to exhaustion during a ~4 min to ~6 min treadmill ramp test procedure increased by 57 sec (23%), which indicates a substantial improvement in running performance. Velocity at VO2max and velocity at lactate threshold increased by 1.8 km∙hr-1 (13%) and 1.4 km∙hr-1 (14%), correspondingly. Furthermore, the participant increased absolute and relative VO2max by 0.33 L·min-1 (9.5%) and 7.5 mL·kg-1·min-1 (13%), respectively. Oxygen pulse at VO2max increased by 2.1 mL·beat-1 (13%), and submaximal heart rate decreased by 12 beats·min-1 (7.9%), while no notable change in running economy was observed, indicating an upsurge in maximal cardiac stroke volume. Moreover, the results indicated an upsurge in relative fat oxidation from ~36% to ~43% of the total energy turnover, which appeared to be due to the substantial improvement in relative VO2max. It can be concluded that HICR of short exercise duration can be effective in improving running performance and aerobic capacity when the initial aerobic fitness level is moderate.

ABSTRACT: This paper is aimed at addressing the car park shortage problem of the Central Business District, CBD, of Jos, the Plateau State capital, Nigeria. The car park dilemma has become a blot in the landscape of the city centre and a negative smear on the tourism destination potential of Jos. A study of the city centre’s car park problem revealed a continuing, incremental trend whose actual magnitude is not easily quantifiable. The purpose of this paper is to evince the major causes of this trend and put forward a plausible, sustainable solution which would address the parking problem such that it is contained as the need arises irrespective of the developmental stride of the city centre. This was achieved by undertaking a field investigation using field observation, physical field survey and enumeration. Through this process, a firsthand vista of the problems and challenges was obtained. Consequently, an Outline Architectural Design proposal of a prototype car park facility that has the potential of add – on – module to address the exigencies of sustainability and adaptability was developed. The proposal also sought to address the unpredictable but surely increasing future car park space needs. Through this means emerged a blueprint for addressing the present car park problems and also the future requirements within the framework of socio – economic, environmental and sustainability needs.

ABSTRACT: The properties and performance of concrete are largely determined by the properties of the cement paste. Admixtures in concrete confer some beneficial effects such as acceleration, retardation, air entrainment, water reduction, plasticity etc., and these effects are due to their action on cement. Classical chemical additives to concrete are considered as one of important factors for improving the properties of concrete in structural designs. Today the construction industry is in need of finding effective materials for increasing the strength of concrete structures with low cost, and with less environmental damage. This research was aimed at addressing such issues by investigating the suitability of Jute leaf powder as an admixture in concrete production. At 7 days hydration period in water, the control had a compressive strength of 18.50N/mm2, it was observed that the introduction of jute leaf powder increases the compressive Strength of the concrete expect in the case of 0.2% where there is a decrease in strength compared to the control cubes throughout. At 28 days hydration period in water, the control had a compressive strength of 28.33N/mm2, it was observed that at 0.2% admixture dosage, the concrete had the lowest compressive strength of 26.00N/mm2. Other percentages are high but that of 0.4% concrete cubes is highest. This shows that the optimum value is 29.01 N/mm2 at 0.4% of admixture. The Flexural Strength results revealed that the concrete with all different admixture dosage levels increases in strength as the admixture percent increases. At 28days, the concrete beams with 0% admixture developed strength of 3.92N/mm2 while the 0.05%, 0.2% and 0.4% had a flexural strength of 3.98N/mm2, 5N/mm2, and 5N/mm2 respectively. Therefore an increase in jute leaf powder increases the flexural strength of the concrete beams. The work shows that compressive strengths of 94.71%, 91.76% and 102.4% of the control (0%) can be achieved at the 28-days. The admixture ratio of (Jute/cement) was ranging between 0-0.4% by weight with mix proportion of (1:2:4) (cement:sand:gravel) by volume and same water to cement ratio (W/C) of 0.57. The experimental tests show that when modified concrete is compared with the normal concrete (without admixture), there is an increase in concrete compressive strength and flexural strength with increase in the ratio of jute leaf powder to certain percentage. Thus, the Jute leaf powder has shown promise as a low-cost concrete admixture in terms of increasing the setting time of concrete.

ABSTRACT

The study analysed trend in temperature and wind speed characteristics over Fidii area of Makurdi Local Government Area of Benue State. Temperature and wind speed data for Makurdi synoptic weather station for a period 30 years (1986 and 2015) were acquired from Nigerian Meteorological Agency, Oshodi, Lagos. Least Square Regression Model (LSRM) was used to analyse trend, while Student’s ‘t’ Test statistic was to determine the significance of the trends at 0.05 degree of confidence. Mean, standard deviation and coefficient of variation were also employed in data analysis. The result shows that the variation in mean minimumm, maximum and mean temperatures over Fiidi area of Makurdi indicates negative trends which were not significant at 0.05 confidence level. The result further shows that temperatures in Makurdi have periodicity of ten (10) years which means that Makurdi usually go through cooling and warming phases in cyclic pattern of ten years with maximum temperatures currently going through upward oscillation (warming phase) after a downward oscillation of just six years instead of the usual 10-year periodicity. The result generally showed that wind speed over Fiidi, Makurdi varied seasonally during the study period with the months of December – April which constitutes dry season in Makurdi have high wind speed with the highest wind speed of 5.78m/s occurring in the month of April, while the lowest wind speed of 3.52m/s on average occurred in the month of October. Annually, result generally indicates a sharp declining trend in the wind speed in the study area during period with yearly decreasing rate of 0.0485m/s. Wind speed showed greater degree of variability than temperature characteristics. Consequently, the study recommends tree planting so as to ensure moderate temperatures that would enhance physiological comfort of the inhabitants.

ABSTRACT: This study assessed the abattoirs in Kaduna metropolis, Nigeria. This came about based on the recognition of the disposal of meat waste as source of environmental pollution in the built environment. The study aimed at assessing the facilities available at abattoirs in the metropolis. This was achieved through the following objectives; identifying the existing abattoirs; assessing the location and their distribution; also assessing the condition/adequacy of the environment. Survey adopted for this study is the survey research method which involved field observation, land use survey. A total of twenty-three slaughterhouses were identified in the study area; two standard abattoirs and twenty-one are substandard. Findings revealed most of the abattoirs are sited without consideration to where, how and what should be done about the waste generated by the abattoir and how this waste will be taken care of; abattoir waste both solid and liquid with exemption of plastics are biodegradable and can be controlled and managed using best practices in waste management and disposal practices. Most of the abattoirs in the metropolis don’t have basic ancillary facilities and services necessary for the daily functional operation of an abattoir; abattoirs contribute to the emission of smokes into the atmosphere through the burning of hides and skins, hoofs, heads and tails and bones. The study recommended ten new slaughter houses to be added to the twenty-three existing already. Slaughter houses are to be properly located using the specification of the World Health Organization (WHO) and Food and Agricultural Organization (FAO). The travel distances should be implemented based on the accepted services and travel distance of not more than 1.6km for the slaughter slabs and 3km for the medium and standard abattoirs. The Kaduna Environmental Protection Agency (KEPA) and the ministry of Agriculture should come together and develop a standard on abattoir hygiene to reduce environmental degradation, waste storage, and improve on treatment of abattoir waste management and disposal.

ABSTRACT:

The paper looked into Covid-19 and Education in Tertiary Institutions in Rivers State.  Covid-19 brought about so many issues resulting to learning lacuna in our tertiary educational institutions in Rivers State.  The paper deployed secondary sources of textbooks, internet sources, and newspapers in generating literature.  It covered the concept of novel covid-19 pandemic. It x-rayed students learning abilities under the ravaging covid-19 era, economic strength of students and parents to acquire learning facilities, and the remote learning under covid-19.  The experiences of learning gap, the general impact on our educational system were equally examined.  The paper concluded that Covid-19 obstructed learning and teaching activities in tertiary institutions in Rivers State. Parents and students had a drop in their economic life to enable them buy data and other materials to cope with the new normal method of learning.  The remote learning and teaching was entirely novel to the tertiary terrain in Rivers State.  There were no initial training and change management approach prior to the emergency which gulped the entire world.  The paper suggested that management of tertiary institutions in Rivers State, should from time to time organize seminars and workshops on e-learning, the e-learning process should be made part of the mainstream learning process by the management of tertiary institutions in Rivers State and that academic staff in tertiary institutions should engage in personal development and not necessarily waiting for management all the time.
