This study was designed to determine the impact of improvised injection molding on students’ psychomotor achievement in general metalwork in technical colleges in Niger State. A pre-test, post-test, non-equivalent control group, quasi-experimental research design was adopted. The study constituted a total number of 122 subjects, 63 for the experimental group, while 59 for the control group. The instruments used for data collection was Metalwork Psychomotor Achievement Test (MPAT). The instruments were also subjected to face validation by three experts from Department of Industrial and Technology Education, Federal University of Technology Minna. The MPAT was trial-tested to determine its psychometric indices and reliability coefficient. The trial test for determining the coefficient of stability of the MPAT was carried out using test re-test reliability method. Pearson product moment correlation coefficient of WCAT was found to be .78. Mean was used to answer the research questions; while ANCOVA was employed to test the hypotheses. The study revealed that students taught metalwork using improvised injection molding had a higher mean score than students taught using the lecture method in psychomotor achievement test. In each mean score of males taught metalwork using improvised injection molding was higher than the mean score of females taught using the same improvised injection molding in the psychomotor achievement test The differences in the mean scores of male and female in the psychomotor achievement test was found to be insignificant. Consequently, the research recommended among others that; Teachers should endeavour to make use of improvised injection molding for teaching relevant area in the curriculum technical colleges with a view to ascertain its usefulness and The private enterprises as such based industries should make available to technical colleges in Niger State spare parts as well as consumable materials needed for teaching Foundry..

Segmentation the image is a very important area of study in color image processing. Many algorithms have been developed for this purpose. However, the segmentation algorithms results suffer from miss-classification and over- segmentation. This is due to the degradation of image quality, during transmission, acquisition and color space conversion. That is why the need of an efficient image enhancement technique that removes the noises or redundant pixels from the color image prior to process of final segmentation arises. In this paper, an effort has been made to analyze and study image enhancement techniques by histogram equalization and adaptive histogram equalization on HSV and L*a*b color spaces separately to search for the better way for color image segmentation. Then, morphological based marker-controlled watershed segmentation technique is used to segment the enhanced images. Lastly, the comparative study is done with the entropy values to measure the performance of image enhancing. Also, compare the minima watershed region for quality of image segmentation with respect to visual perspective. Then, determine the most suitable color space that provides segmentation results more powerfully with respect to those enhancement techniques.

The changes that occurred in the climate systems have become a global challenge. Climate change has impacted on different sectors including agriculture and this calls for urgent attention as food security is of great importance to the economy of a nation and its challenges and prospects differ from different geographical locations. Therefore, this work examined the monthly, annual and decadal distribution, pattern, trends, anomalies of rainfall and temperature in Cross River State, Nigeria. The rainfall and temperature data were obtained from Nigerian Meteorological Agency (NIMET) for a period of 30 years (1997-2016). The measure of dispersion, trend, anomalies was used to analyze the work and results showed the highest monthly mean rainfall was in July with 491.97mm and lowest rainfall was in December with 33.84mm and no august-break was recorded while mean temperature is 28.7oC, the anomalies for rainfall and temperature trend fluctuated greatly with a positive trend. Findings in this study showed that temperature and rainfall are on the increase and such rise in rainfall can result to flooding which can affect agriculture. The study recommends a proper climate monitoring system for farmers to practice early dry season planting to ensure a profitable agricultural practice for food sustainability.

This study investigated the use of Hyphaene thebaica as a sorbent for remediation of crude oil polluted water. The crude Hyphaene thebaica (CHT), retted Hyphaene thebaica (RHT) and bleached Hyphaene thebaica (PFHT) were subjected to sorption studies to optimize their sorption capacity. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. It was found out that increase in sorbent weight led to increase in sorption capacity from 3.71-4.87g/g, 4.30-5.77g/g, and 4.56-6.23g/g in CHT, RHT and PFHT respectively. Increased in Initial oil concentration also increased the oil sorption capacity by 18-24% until it reach equilibrium. Sorption time was varied from 10, 20, 30, 40, 50, 60 and70 minutes and the highest sorption capacity was recorded at 30 minutes before a gradual decreased was observed. Sorption capacity decreased with increased in temperature above 400C. The sorbent exhibited good reusability after 8 cycles, with less than 50 % reduction in sorption capacity. These properties introduce Hyphaene thebaica as a potential sorbent for oil cleanup.

Short Message Service (SMS) has become an important form of the mobile communication channel; their popularity is attributed to several conditions including low-cost sending, simple delivery mode and convenient usage. Feature extraction phase has been identified by researchers to be one of the major steps in the Spam SMS detection system. The extraction of features in SMS involves a process of reduction of an initial set of raw features into more manageable forms for processing. This paper employed a new One Dimensional Ternary Pattern (1D-TP) for SMS feature extraction while the simulated annealing was applied to optimize the extracted features. Experimental results showed a better objective function.

Urinary calculi is a common genito-urinary disorder in the modern era. They may cause pain, nausea, vomiting, hematuria and possibly chills and fever due to secondary infection. Diagnosis is based on urinalysis and radiological imaging usually non-contrast helical CT imaging. In Ayurveda, urinary calculi are known as Mutrāshmari. This study was aimed to evaluate the efficacy of Gokshurabija choorna (GBC) comparatively with Cystone® in the management of Mutrāshmari. The formula was prescribed in Bhaishajya Rathnāvali under the chapter of Mutrāshmari chikitsa. Twenty patients with urinary calculi were randomly selected from Gampaha Wickramarachchi Ayurveda (Teaching) hospital, Yakkala and D. B. Welagedara Ayurveda (Provincial) hospital, Kurunegala. They were divided into two groups (Control and Test) using the simple random sampling method. Test group was treated with 10g of GBC with hot water twice daily for a period of seven days. Two tablets of Cystone® was recommended twice daily for a period of seven days to the control group. Appropriate patyāpatya were instructed to follow during the period. Data was collected before treatment, after treatment and after seven days follow-up period using USG (for objective parameters) and self-prepared questionnaire (for subjective parameters). Results were analyzed by using IBM SPSS v22 statistical software. After fourteen days of treatment, both groups showed a significant effect to some clinical symptoms. But calculated p values of GBC were less significant than Cystone® comparatively. It was concluded that GBC has got effectiveness as a treatment of Mutrāshmari. No adverse reaction was observed during treatment, proving the formulation is safe and effective.

This study was carried out to determine the levels of lead and cadmium in the liver, kidney and muscle of cattle slaughtered in three slaughter slabs in Akure, Ondo state, Nigeria. Heavy metals (HM) as well known through scientific knowledge can build up in the soil, leading to severe environmental pollution and contamination of the food chain which is of global public health importance. This study therefore emphasized on the need for continuous monitoring and control of heavy metal residues in cattle slaughtered for human consumption. Five animals each were sampled from Shasha (SH), Onyarugbulem (ON) and Ilara mokin (IM), collecting their liver, kidney and muscle. The samples were assessed for lead (Pb) and cadmium (Cd) levels using the Atomic Absorption Spectrophotometer (AAS). Results obtained showed that lead and cadmium levels in samples from SH were in the order kidney > muscle > liver and liver > muscle > kidney respectively. Levels in IM samples appeared in the order kidney > muscle >liver for lead and kidney > liver > muscle for cadmium. While ON samples presented the order; kidney > liver > muscle and liver > muscle /kidney for lead and cadmium respectively. However, significant difference was not observed in lead and cadmium concentrations in all the samples (p > 0.05). Summarily, levels of the assessed metals in this study were within the limits adjudged safe by two International Organizations viz; Food and Agriculture Organization together with World Health Organization (FAO / WHO).

The method of Horace is an inductive method that makes use of elementary transformation of vector bundles. The base step involves proving by hand the cases arising from diagram chasing using appropriate short exact sequences. Proving satisfactorily the maximal rank hypothesis requires proving certain statements for all possible cases. This paper presents a bound that guarantees inclusivity of the base cases arising in the proof of maximal rank hypothesis for P^4 using the method of Horace.

The main objective of this study is to identify the relationship between female headed households and poverty. Secondary data were obtained from the Household Income and Expenditure survey (HIES) 2009/10 conducted by the Department of Census and Statistics to analyze the poverty of female headed households at a national level. The sample size was 20137 households. Binary logistic regression analysis was used for the analysis. The study found that gender of the household head, ethnicity, and employment status of the head, residential sector, marital status and province are significantly affected on poverty among the households. Further, it revealed that Female headed households are poorer up to a percentage of 60 in comparison to male headed households. Poverty is higher among widows and the married group. The findings of the study highlighted that better education, investment in skill training and promotion of social dialogue between industrial partners to create a working environment is critical to encourage women to engage in marketing activities and it will reduce poverty among them.

The activity concentrations of uranium in rainwater from selected areas in Akwa Ibom State, Nigeria were measured by the means of a gamma-ray spectrometry using a sodium Iodide Thallium doped NaI (TI) detector. The results gotten were used to calculate the radiological risk of human over lifetime consumption by the population in the area. The mean activity concentration for Uranium in all the rainwater samples from all the areas was 5.2 + 0.88 Bq.L-1 with a range of 1.2 + 0.21 to 15.00 + 2.92 Bq.L-1. The mass concentration was obtained ranges from 46.74 ± 8.46 to 602.86 ± 117.67 µg.L-1. The radiological risks for cancer mortality risk ranged from 4.3 × 10-5 to 5.6 × 10-4, while that of the morbidity risk ranged from 6.5 × 10-5 to 8.5 × 10-4 these values were found to be low. The chemical toxicity was found to vary from 1.28 to 16.51 µg.kg-1.day-1 while the hazard quotient ranges from 2.13 to 27.53 and these values are above the recommended acceptable safe level by various international organizations. Therefore, it is recommended that regular monitoring of rainwater in these areas should be carried out and also, adequate measures such as providing clean and properly treated water to people living in those areas should be taken

Construction industry is a major consumer of materials in large quantities and a producer of large quantity of waste which had led to the gradual decrease of natural resources. Many researchers have utilized natural aggregates in the production of geopolymer concrete but few researches have been carried out producing geopolymer concrete using Recycled Concrete Aggregate (RCA). The research evaluates properties of metakaolin based geopolymer concrete (MKGPC) made with RCA. MKGPC was produced and cured at 60oC in the oven for 24hrs after which they were left to air dry in the laboratory. Conventional Portland cement concrete (PCC) was produced to serve as control. MKGPC and PCC specimens containing RCA at varying percentages of 0%, 20%, 30%, and 40% were produced. Cube moulds of size 100mm x 100mm x100mm was used to cast a total of 96 concrete and properties such as compressive and tensile strength, absorption and abrasion resistance were evaluated after curing ages of 7, 14, 28 and 56days. The average compressive strength obtained at 28 days of curing for PCC specimens with 0%, 20%, 30% and 40% RCA are 24.23N/mm2, 21.09N/mm2, 19.81N/mm2 and 19.37N/mm2, while for MKGPC specimens with same replacement of RCA are 31.54N/mm2, 31.17N/mm2, 28.55/mm2, 26.40N/mm2 respectively. The average split tensile strength of MKGPC specimen was 4.66%, 11.11% and 14.69% while PCC specimen had 15.38%, 23.49% and 25.90% respectively. Water abrasion resistance was found to be higher than the PCC specimens though its absorption capacity was higher than the PCC specimens. This shows that properties of MKGPC containing RCA is higher when compared to that of PCC containing RCA though it has high absorption capacity. The research recommends that metakaolin based geopolymer concete containing RCA up to 40% RCA could be used to produce concrete for structural use.

Packaging is a critical factor in the buying decision-making process of the consumers. Therefore, understanding the role of packaging in consumer buying behaviour is necessary for small- scale entrepreneurs’ survivability. In this study descriptive analysis and Pearson correlation analysis were used to determine the role of packaging in consumer buying behaviour for the small- scale entrepreneurs in Arusha City. The findings revealed that the label of the package is important in the decision buying process, the quality of the packaging material is important during the buying process, and packaging color impacts consumer behavior during the buying process. Society culture, business culture, customer’s family culture, and customer’s lifestyle culture were important factors towards customers buying behavior. Also, the study indicated the existence of the relationship between the small-scale entrepreneurs packaging practices and the buying behavior of consumers in Arusha City were the factor for small-scale entrepreneurs to compete with other products from outside the country. The study recommended that small-scale entrepreneurs in Arusha City should be creative and innovative in terms of packaging. It was also recommended that the Government through the Small Industries Development Organization (SIDO) should train the small-scale entrepreneurs in Arusha City on packaging related matters to promote customer buying behavior.

This research work was carried out to investigate the effect of drying methods on functional properties and pasting behaviour of bitter yam (Dioscorea dumetorum) flour. Flour processed from bitter yam tubers was subjected to sun drying and oven drying methods at 4% moisture contents level, under the temperature of 32.3 ± 0.20C and 61.8 ± 0.20C at 6% respectively. The results showed that the oven-dried bitter yam flour had higher water absorption capacity (173g/g) and oil absorption capacity (341g/g) compare with lower values of 165g/ g, water absorption and 298g/g, oil absorption capacity for sun dried bitter yam flour. It was also observed that oven dried flour had lower foaming capacity and foaming stability of 5.3% and 3.5% respectively compared with sun dried flour with the values of 5.9% and3.9% for foaming capacity and foaming stability respectively. Furthermore, Sun-dried bitter yam flour showed greater pasting characteristics for peak viscosity (73.18 RVU) and breakdown (19.63 RVU) compared to that of oven-dried flour of peak viscosity (65.96 RVU) and breakdown (3.71 RVU). On the other hand, it was observed that oven dried flour possessed higher holding strength, final viscosity and setback pasting characteristic compared to sun dried flour. While the sun-dried flour produced higher peak viscosity and breakdown pasting characteristics compared to oven-dried flour, the peak time is insignificantly different. This study showed that a low temperature dry method (sun drying) could be employed for processing bitter yam into flour for considerable application in food formulations especially when flour with high functional characteristics for foaming capacity, foaming stability, emulsion capacity and emulsion stability is to be considered. Oven dried bitter yam flour should be considered when high water absorption capacity, high oil absorption capacity and high reconstitution index are of high priority.

The experimental group consisted of 319 students from 8 schools. They carried out experiments using micro science kits. The control group consisted of 321 students from the other 8 schools. The control group performed experiments using conventional apparatus. A Physics Process Skill Checklist (PPSC) was used for Data Collection. The instrument was validated by experts and the reliability co-efficient obtained was 0.84 using the test-retest method and followed by the Pearson Product Moment Correlation analysis. The data collected were analyzed using mean and standard deviation as descriptive statistics while t-test and analysis of covariance (ANCOVA) were the inferential statistics used to test the hypotheses test at 0.05 level of significance. The results revealed that students’ use of micro science kits had a significant effect on science process skill acquisition in physics practical work. It also revealed that school type was a significant factor in students’ science process skill acquisition in physics. Based on the findings of this study, it was recommended among others that teachers’ should update their knowledge on the integration of micro science kits in teaching of practical work for enhancement of students’ acquisition of science process skills in physics

Pathloss exponent is one of the most important parameter which has been considered widely in wireless communications analysis. It determines the rate at which the signal reduces as the distance (LOS) between the transmitter and the receiver increases and this parameter enhances the effective propagation of radio signal. This paper investigated the radio signal propagation profiles at 88 MHz at various elevation levels. In this work, a Retekess TR501 FM long range instrumentation was used as transmitter. This instrument is capable of transmitting audio signal at VHF band and the signal strength was measured quantitatively across the regions along several routes with the aid of a hand held spectrum analyzer. A global positioning system (GPS) receiver was used to determine the elevation above ground level and the geographic coordinates for four different itinerary in hilly environment. The line of sight (LOS) of the various data points from the transmitter was determined using a digital distance meter. The measured data obtained were compared with existing standard models (Free-space, Egli and Irregular terrain model). The findings revealed that, the average measured values was in good agreement with optimized Egli model having the MAE of 7.10 dB, MAPE of 3.20% and RMSE of 4.80 dB which is within the acceptable international standard range while Free space model underestimated the measured values. The work also shows that the path loss increases with increasing line of sight and the mean path loss exponent obtained in this region is 2.18 which is within the acceptable international standard range for urban environment. Furthermore, it was revealed that, radio signal strength depend directly on elevation regardless of LOS between transmitter and receiver, that is, the signal strength is enhanced at higher elevation point than lower elevation.

The study examined the relationship between firm’s characteristics and cash holdings of listed consumer and industrial goods firms in Nigeria, South Africa and Kenya. Out of 35, 23 and 15 listed consumer and industrial goods firms in Nigeria, South Africa and Kenya respectively, we sampled fifty-two (33 for Nigeria, 12 for South Africa and 7 for Kenya) firms for a period of 8 years (from 2011-2018). The main type of data used in this study is secondary in nature; sourced from the financial statements of the selected firms via Nigerian Stock Exchange (NSE), Johannesburg Stock Exchange (JSE), and Nairobi Securities Exchange (NSE). This study applied ex-post facto research design. The data collected were analyzed using Pearson product-moment correlation matrix. The results revealed that in South Africa, firm size (FSIZE) was statistically significant at 5% with its t-value as 2.083134 and p-value as 0.0400; while in both Nigeria and Kenya, it was statistically insignificant at 5% with its t-values as -1.000160 and-1.900007 and p-values as 0.3182 and 0.0631 respectively. In Kenya, leverage (LEVG) was statistically significant at 5% with its t-value as 3.850902 and p-value as 0.0003; while in both Nigeria and South Africa, it was statistically insignificant at 5% with its t-values as 0.985502 and -0.584775 and p-values as 0.3253 and 0.5601 respectively. In Nigeria and Kenya, profitability (PROF) was statistically significant at 5% with its t-values as 5.889308 and 4.249736 and p-values as 0.0000 and 0.0001 respectively; while in South Africa, it was statistically insignificant at 5% with its t-value as 0.435708 and p-value as 0.6641. Finally, dividend policy (DIVP) was statistically insignificant at 5% in Nigeria, South Africa and Kenya with its t-values as -1.098510, 1.691096 and 1.234615 and p-values as 0.2730, 0.0942 and 0.2226 respectively. In view of the discoveries of our investigation, a financial specialist can sensibly reason that an organization with high leverage ought to like to hold more money. The higher leverage recommends higher office costs; this may be because of the potential size of riches move from obligation holder to investors. Thus, insightful supervisors will need to abstain from holding over the top money saves as this would pull in examination from the capital markets.

Since the return to democracy in 1999, Delta Sate is yet to achieve its grand quest of free quality education for its indigenes. Rather, the war against illiteracy, students drop-out, teachers strike actions and other insecurity challenge that distorts the realization of quality education in public secondary schools remains unabated. The study examined emerging and existing factors that confront the realization of quality education in secondary schools in Delta State. Methodologically, the study strictly utilized the documentary method and data were sourced through the secondary sources and analyzed in content. The study found that insecurity and global health crisis as emerging factors will worsen the existing leaning inequalities among secondary school students in Delta State. Also, if these emerging factors are not tamed, they will solidify with the existing factors to thwart government efforts towards achieving quality education in the State. The study recommended among others: that the ministry of Basic Education in synergy with other stakeholders should fence and provide security personnel to porous schools.

The study was designed to determine the effect of guided inquiry teaching strategy on students’ academic achievement in Chemistry. To this end three research questions which were transformed into three hypotheses guided the study. The study adopted the quasi experimental design of the pre-test post-test nonequivalent control group design. One hundred year two undergraduate students of Ignatius Ajuru University of Education and Rivers State University were randomly selected and assigned into two groups; fifty students for the experimental group (guided inquiry group) and the other fifty students for the control group (discussion group). After four weeks of the teaching of the twelve principles of Green Chemistry such as waste preventions, atom economic, less hazardous chemical synthesis, designing safer chemicals, safe solvent and auxiliaries design for energy efficiency, use of renewable feed stocks, reduce derivatives. catalysis, design for degradation, real-time pollution prevention and safer chemistry for accident prevention, a 36 multiple choice objective questions which was well validated and had a reliability co-efficient of 0.92 were administered to the students in the two groups before and after the application of the teaching strategies on the two groups. Mean, standard deviation and ANCOVA were the statistical tools used for data analysis. The result of the study reveals that students in the experimental group i.e. guided inquiry group did significantly better than their counter part in the control group i.e. discussion method group. It was also found out that student achievement do not significantly differ on the basis of university type. In addition, degree types (B.Sc./B.Sc.Ed) has significant influence on student achievement in favour of the B.Sc. students. Consequently, it was recommended among others that guided inquiry as a teaching strategy should be adopted by university lectures in delivery their lesson especially in the teaching of concept such as Green Chemistry.

Multi-drug resistance in Salmonella species is becoming a great problem in healthcare institutions resulting in high mortality rate due to its infections. Hence, the purpose of this study was to evaluate the antibiogram of Salmonella species obtained from various environmental samples in Ogun state. Samples (150) comprising faecal droppings of cow, goat, bird and pig as well as pond wastewater were obtained and Salmonella species were isolated using Xylose Lysine Deoxycholate agar and identified using analytical profile index. The susceptibility of the species was evaluated and interpreted according to CLSI guidelines. Fifty (50) species of Salmonella species were obtained and all (100%) were resistant to ceftazidime, gentamicin, while 92%, 90%, 48%, 46%, and 44% were resistant to amoxicillin/clavulanate, cefuroxime, cefixime, ciprofloxacin, ofloxacin, and nitrofurantoin respectively. Multi-drug resistance was noted in Salmonella species to at least three antibiotic classes. The results revealed high prevalence and multi-drug resistant Salmonella species in our environment. Hence measures should be implemented urgently to curb further spread of multidrug resistant Salmonella species in our environment.

The concept of fading and signal propagation design remain very vital to a radio Engineer because of the unstable nature of environment the signal traversing. Precise estimation of Geoclimatic factor (K) and effective earth’s radius factor (k) which depends on temperature, relative humidity and pressure are highly essential for radio signal propagation in clear air so as to provide for fade margin. In this work, the Geoclimatic factor has been obtained using Radiosonde data for two different locations (Ibadan and Ilorin), Nigeria. The K-factor obtained was used to determine the multipath fade depth exceeded for 0.01% of time and the result revealed that the k and K have monthly variations and they are locations dependent. Specifically, Ibadan and Ilorin has annual mean geoclimatic factor of 0.000293 and 0.000185 respectively. Also, the annual mean k-factor obtained in the two locations are 1.475 and 1.548 respectively. These values are higher than the standard value of 1.33 as predicted by ITU-R and the implications of the result is that, propagation in this geographic locations are mostly Super-refractive. From the monthly and annual K-factor presented, the percentage of time a given fade depth exceeded for the 20 GHz increases rapidly with increasing link distance in the two locations and the fade depth also increases with increase in frequency at a fixed distance. This is due to the fact that as the path length increased, the multiple reflections leading to multipath also increases and this leads to multipath fading. The overall results can be used for microwave link design in these locations.

Machine learning methods have been used in various fields to enhance automation and the ability of computer to learn from experience for decades. Its application in drug discovery is emerging and is now being integrated into the process especially in the early stage for lead compounds screening. The antibiotic discovery process is cumbersome considering the duration and inadvertently the resultant cost. So, the application of deep neural networks will help in efficiency by reducing the duration of process and the overall cost of the process. A deep convolutional neural network successfully predicted new broad-spectrum antibiotic, Halicin, with other molecules with distinct structures. The deep learning models have been engaged to learn from known useful chemical compounds (molecules) with their biological activities. The use of the artificial intelligence techniques in the antibiotics discovery will be reviewed with focus on the deep neural networks model as compared with other methods.

Noise pollution is a major threat that affects the well-being of man in urban areas. This study assessed the noise pollution levels at major motor parks in Ilorin Metropolis, Kwara State, Nigeria. A total of Five (5) major motor parks were selected within the Metropolis namely: Offa garage motor park, Soludero Motor Park, Maraba motor park, New-Shao garage motor park and Saw-mill garage motor park. Noise levels assessment in the motor parks were measured using a Benetech GM 1357 factory-calibrated sound level meter. Measurements were taken at three points in each motor parks, making a total of fifteen points in all. The assessment took place in the morning between the hours of (6.00am-8:00am) ,afternoon (12-2:00pm) and evening (4:00-6:00pm) three times weekly in alternate days for four weeks. No night time assessments were made. The results revealed that with the exception of Offa garage motor park with 69.94 dB(A) that was slightly lower and within the 70 dB(A) WHO standard, all other motor parks had levels that were above the WHO recommended limit. Results showed exceedance of 60 dB(A) National Environmental Standard and Regulation Enforcement Agency (NESREA) recommended permissible limit in all the motor parks. The motor park with highest noise levels is Saw-mill garage motor park with mean noise value of 74.45 dB(A) followed by New-Shao garage motor park with 72.24 dB(A) then Maraba motor park having 71.74 dB(A) while Soludero motor park had 71.48 dB(A) and the least noise level was recorded at Offa garage motor park with 69.94 dB(A) . This study provides and creates awareness on the implications of noise in motor parks .The lead source of noise is vehicular activities as observed during the assessement. The findings of the study provide information on the state of noise pollution in the motor parks and likely impacts on those that engage in activities in the motor parks. The study recommended that for vehicular noise pollution, it is important for the management of the motor parks to enlighten the drivers and vehicle owners the need to repair and maintain their vehicles to reduce the noise at source. Also, there is need for sporadic monitoring and assessment of noise levels in motor parks so as to provide relevant data on the state of noise levels in motor parks in urban centres, this will bridge up the data gap challenges. In ensuring the health effects of noise is prevented, there is need for the Ministry of Environment and other environmental regulatory agencies to create awareness and sensitize the public on the dangers of noise pollution. Strict actions on noise pollution should be done by the Ministry of Environment to ensure strict compliance to noise. Lastly, the need for periodic auditory examination and screening of motor park users and workers should be carried out for individuals who use and perform activities in motor parks.

This study examined the influence of gender and students’ self efficacy beliefs on motivation to learn secondary school mathematics in Laikipia County, Kenya. The study was guided by Keller’s ARCS model of motivation. Descriptive research design was employed in the study. The target population comprised of all 8357 Form Four students in Laikipia County .Simple random sampling was used to select sample schools and respondents. A sample of 392 students (276 males and 176 females) was selected for the study. A self-administered questionnaire was used for data collection. Cronbach’s alpha was used to estimate the reliability of research instruments. Data was analyzed using t- test and simple regression analysis. The study findings revealed that male students had a significantly better motivation to learn mathematics than female students, and that students’ self-efficacy beliefs contributed significantly to students’ motivation to learn mathematics. The study concludes that mathematics teachers should apply appropriate motivational and self- efficacy enhancement strategies in improving students’ motivation to learn mathematics.

The coronavirus disease 19 (COVID-19) is a cross-cutting concern worldwide disrupting societal and scientific norms. However, the opportunities and challenges it presents calls for a focus on upstream thinking framework to address equitable access to testing and treatment options. An essential component in defining a clear case for COVID-19 is mass testing as well as addressing the barriers to uptake. A well-defined case is essential for isolation, quarantine, management, and contact tracing that can help control the spread of SARS-CoV2. As the global understanding of SARS-CoV2 evolves, reimbursement already plays a crucial role in reducing health care costs. There is currently a scarcity of debate regarding cost reimbursements and its role in COVID-19 mass testing. Understanding reimbursement role is key to ensure sustained access to testing especially in resource limited setting where majority of the most vulnerable populations live.

Sample is a fractional part of population. Sampling is the act of selecting sample from whole population for required information in order to take decision. Sampling techniques are the methods used to select samples from whole population which are in two ways probabilistic and non-probabilistic sampling. Two probabilistic sampling techniques were compared in this paper, simple random sampling with use of random number table to select samples and systematic random sampling with fixed sampling interval to other take samples after first randomly selected sample. The standard error value of simple random sampling is the least compared to that of systematic random sampling and therefore simple random sampling technique gives the best precision.

Hypercomplex numbers have played a notable and critical role in the study and exploration of Loop Theory. Researchers have made numerous studies in this area especially in the investigation and construction of different loops. This paper has extended the research to C-loops where we are investigating the formation of C-loops obtained from hypercomplex numbers of dimension 2n ; 1 ≥ n ≤ 4. We are specifically working with the 24- dimensional algebra, called the sedenions. In constructing the C-loops, we have used the frame multiplication of hypercomplex numbers using the Cayley-Dickson construction. We have tested the satisfaction of the left, (x x) (y z) = (x (x y)) z and right, x ((y z) z) = (x y) (z z) C-loop identities by the sedenions. We have also formed split extension of sedenions and equally tested the satisfaction of the C-loop identities on them. We have found that the sedenions satisfy the C-loop identities hence forming C-loops. However, the split extension of sedenions satisfies the right C-loop identity only.

The entire world including Nigeria is currently battling the coronavirus 2019 (COVID-19) global pandemic. The pandemic has affected all aspects of human lives and world economy without any form of exemption to the Nigeria economy. The foreign exchange rate has witnessed a dwindling effect since the rise of the pandemic in Nigeria. It is based on the aforementioned that this paper has examined the impact of the COVID-19 on the Nigeria economy with empirical evidences from the foreign exchange rates. Expo facto research design was used to collate secondary data from the Nigeria Centre for Disease Control (NCDC), Central Bank of Nigeria (CBN) and Nairametrics covering the period April 1 to June 30, 2020. The data were analysed with Microsoft Excel and IBM SPSS using descriptive statistics. The findings reveal that a negative relationship exist between the impact of the COVID-19 and the value of the naira against the dollar. The study concluded that there is no relationship between COVID-19 and the Nigeria foreign exchange rates. The study recommends that the government and its agencies should focus more on other economic factors like oil price and importation to manage the exchange rate instead of COVID-19.

Lead which is toxic to the environment because of its threat on living organisms is one of the common components of industrial effluent. Urea-activated melon husk was used as an adsorbent to remove lead from simulated industrial effluent. Exposure times, adsorbate concentrations and adsorbent dosages were varied for the most suitable set of conditions for the adsorption process. The Adsorption isotherms correlated fine with the Langmuir and Freundlich isotherm models, with their R2 values 0.9999 and 1 respectively. Data from the experiment were also assessed to discover the kinetic characteristics of the adsorption process. Adsorption process for the target heavy metal ion was found to follow pseudo-second order adsorption kinetics with r2 value of 0.9995. Urea-activated melon husk, a readily available adsorbent, was found to be efficient in the uptake of Pb2+ ions in industrial effluents, thus, indicating an excellent alternative for the removal of heavy metals from industrial waste water.

This article which is qualitative in nature examines quality control in organizations with emphasis on Nigeria’s manufacturing and the education sector. Secondary source constituted the main source of data for this article. The essence of this article is to explain the objectives and steps towards the implementation of quality control plan in an organization. Because it is imperative to ensure and maintain quality standards in an organization, to ensure that product quality is maintained, manufacturing errors are reduced or eliminated, and the quality of service are improved. The study recommend that the government should meet the recommended 26% educational spending prescribed by UNESCO, which will boost higher education system in Nigeria. Higher institutions in Nigeria should set up internal quality assurance and monitoring of lecture units to enhance good quality delivery. There should be a review of curriculum content in order to meet the current societal needs of the people. The article further recommended that for the manufacturing sector, organizations should be able to device the quality control measure suitable for their products and be able to fund their quality control plan and measure, this will enhance the quality of their products and the trust the customer have on them. And the government monitoring team should intensify effort in monitoring and certifying the products produced in these organizations.

Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people who fall sick with COVID-19 experience mild to moderate symptoms and recover without special treatment. A number of deaths have been recorded across world. The aim of this study is to investigate and compare the extent the virus affects Africa relative to other parts of the world and it significant. Fifty five countries were selected randomly based on their continents and cases of infection. Data from each country were obtained from United Nations Geoscheme and WHO and were analyzed and compared to that of the United State of America (USA). USA was used as a Comparism Factor (CF) because it has one of the best healthcare system and high COVID-19 cases. Subsequent examination of associations between the proportion of COVID-19 cases, recovery and deaths of each country to the United State of America was carried out. All data used in these analyses are from publicly available data sets. Data analyzed revealed that with exception of South Africa, Africa appears to be least affected by the virus. African countries have the least infected, more recovery and lesser number of deaths index. Result from the study suggests that the virus affect Africa the least when compared to USA and other continents in terms of cases and mortality. This may be due to among other factors a more robust immune response. The result also helps to provide insight as to how significant developing and providing vaccine may be to this part of the world.

In Kenya, nutrition education is included in the school curriculum as recommended in the year 2009 national school health policy. Nevertheless, policy advocacy and communication strategies on nutrition are relatively weak, and there is insufficient focus on operational research on nutrition. In addition, nutrition education is not taught as a standalone subject and is only infused in science subjects. Consequently, the malnutrition problem is not as well understood as it could be. Modern malnutrition consists in over-consumption of energy dense and fatty foods. These have led to an upsurge of non-communicable and lifestyle diseases such as cancer, diabetes, bone and heart conditions. Therefore, there was need to find out strategies on eating habits in order to help pupils acquire discriminative skills among foods. The pupils can act as agents of change in the community through the symbiotic relationship that exists between the school and the society. This will be the first stage towards curbing the food- related health problem. The purpose of this study was to establish strategies promoting healthy food choices among pupils. The Health Belief Model as a predictor of preventive health behaviour was the guide theory for this research. The study was mainly descriptive in design with purposive sampling. The target population was pupils in Nyeri County with their teachers and parents. Data collection tools were semi-structured interviews, and focus group discussions, food diary, and FFQ. Data was analyzed both qualitatively and quantitatively guided by the themes from research objectives. Quantitative data was analyzed using basic descriptive statistics and presented in form of tables, pie charts, graphs, and percentages. The Qualitative analysis involved narrative records and respondents’ quotations. The study established strategies that would promote healthy food choices key among them being healthy snacking. The study findings may be used by the Ministry of education to inform nutrition education content in the school curriculum.

Plant plays important roles in environmental clean-up geared towards a sustained eco-friendly environments. Myriads of environmental pollutants from natural and anthropogenic activities are mopped up by certain plants via phyto-based mechanisms. This processes are highly regulated by phytoenzymatic and non-enzymatic activities. The uptake of contaminants via the plant roots for further biochemical processes within the plant tissues utilizes apoplastic pathway (passive diffusion process) and symplastic pathway (an energy dependent process). However, certain pollutants that are not taken up by plants are transformed into less harmful and eco-friendly molecules by the activities of endophytes within the plant roots. Phytomechanistic processes utilized by plant to remediate contaminated environments include; phytoextraction where pollutants in soil, sediments and groundwater are taken up into plant tissues or adsorbed into the roots for storage and further biochemical activities; phytodegradation where toxic pollutants taken up by plants are metabolized by phytoenzymes into non-toxic molecules; phytostabilization where the environmental pollutants are immobilized, precipitated and adsorbed within the root zone via the release of plant exudates in synergy with endophytic activities; and phytovolatilization which involves pollutant uptake and subsequent transformation into an eco-friendly compounds that are released into the atmosphere. Phytoremediation strategy for remediating contaminated environments has enormous merits over other conventional environmental remediation techniques. However, by understanding the mechanisms and the phytometabolic events occurring within plants used in phytoremediation, a new paradigm geared towards effective phytotechnological advancement and application with high ecological impact can be gained, hence the focus of this review.

In Bangladesh the safety precaution and working condition of tannery workers are very disappointing. The tannery workers are always coming in contact with different chemical exposure and different heavy metals are inserting into their body organs. The aim of this study was to determine selected heavy metal levels including cadmium (Cd), Chromium (Cr) and lead (Pb) in scalp Hair of tannery workers and find out the Relationship between the chromium concentration in workers hair and their working duration. Human hair sample of different tannery worker were collected from different tanneries in Bangladesh and samples of individual were analyzed for heavy metals (Cd, Cr and Pb) by Flame Atomic Absorption Spectro photometric technique (AAS). The results of replicate analysis shows the following mean concentrations in (mg/kg): Cd = 0.04± 0.085, Cr = 5.85 ± 0.8391, Pb = 1.3 ± 0.0465. Comparing with others study around the world, the result shows that the presence of chromium is in very large amount in Bangladeshi tannery workers hair, lead in relatively large amount and cadmium is in small amount.

Pesticides provide protect to grains against destructive pests but its residues or metabolites has been linked to various health challenges. Its lipophilic nature and consumption of food with residue results into the accumulation of the residues beyond the level which the body can handle which leads to gradual deterioration of health and eventual emergence of disease state. The aim of this study is to assess nine (9) composite samples of the grains that are mostly consumed in the study area (millet, maize and beans) in order to ascertain presence of pesticide in grans sold I the study area. Samples were randomly collected from three (3) major markets in Ilorin Kwara State, Nigeria. Laboratory Analysis was carried out by extraction method for de-fatting of the samples. Qualitative and quantitative analysis were performed using gas chromatography with electron capture and flame ionization. All the nine (9) samples (100%) contained several pesticide residues which are not conventional with hexadecanoic acid (with mean value of 21.07, 33.06 and 13.38 in millet, maize and beans), hexadecanoic acid, methyl ester (with mean value of 4.43, 7.95 and 5.43 in millet, maize and beans) and 9, 12 octadecanoic acid (with mean value of 9.41, 19.10 and 4.57 in millet, maize and beans) recorded in all the samples collected from the three (3) markets. Hexadecanoic acid, an acaricide pesticide residue that is neither classified by WHO nor approved by EU for use as preservative. No residue of conventional pesticide was detected in any of the samples analysed which is an indication that use of conventional pesticide is phasing out among the traders in the markets surveyed.

Potassium trisoxalatoferrate (III) trihydrate complex, K3[Fe(C2O4)3].3H2O was synthesized and characterized using UV-Visible and FT-IR spectrophotometry. Its antibacterial properties was evaluated using three(3)different bacteria strains namely: Escherichia coli, Staphilococus aureus and Bacillus subtillus. A commercial drug, ciprofloxacin was used as control. The results of the analysis showed that escherichia coli was not sensitive to the complex. However, staphilococus aureus and bacillus subtillus were sensitive to the complex at a concentration range of 100 - 400mg/ml and 200 – 400 mg/ml respectively. The results of minimum inhibitory analysis and minimum bactericidal analysis showed that the complex could not inhibit the growth of escherichia coli, but it inhibited and destroyed staphilococus aureus and bacillus subtillus at some range of concentration.This study has revealed that the complex, potassium trisoxalatoferrate(III) trihydrate has some medicinal potentials as likely antibacterial agents

This study examined the effect of employees training on employee’s performance in Arusha Municipality. A sample of 80 respondents was selected through purposive, probability and simple random sampling procedures, 80 respondents filled the questionnaire which was validated through expert in public sector. Reliability test yielded the Cronbach’s Alpha of above 0.7 meaning the questionnaire was reliable for data collection. Data was analyzed through descriptive and inferential statistics to determine the effects of employees training on job performance. The study observed that training have strong effect on employees’ performance. This was indicated by the fact that respondents regarded positively with strength the relationship of training and job performance. Training strategies was another investigation in this study. Short courses training and seminars were more preferred to respondents than forum and workshops for building capability of the trainees. The study recommended that public institutions should increase financial resources allocations to employees’ short course training and seminars to adequately equip workers with high capability. From time to time, the Arusha Municipality should be reviewing its human resources development plans to cater for the new demands of the customers of an institutions’ plans so that whenever it send employees for training should aim at filling the identified gaps or fixing an observed development opportunity. The Arusha Municipality should constantly make assessment and ensure its performance stability prevails with the required skills of employees.
