In different processes ranging from conversion, utilization & recovery of thermal energy in various industrial, commercial & domestic applications heat exchangers are used. Economical design of heat exchangers, which can help to utilize energy, use economical material and help in reducing cost should be achieved by increase in the performance of Heat exchanger. Use of Heat transfer enhancement techniques lead to increase in heat transfer coefficient but at the cost of increase in pressure drop. Therefore, while designing a heat exchanger, using any of these techniques, analysis of heat transfer rate & pressure drop needs to be done. To achieve high heat transfer rate in an existing or new heat exchanger several techniques have been proposed in recent years. This work presents the study of heat transfer enhancement of a circular heat pipe using nano particles produced as a result of wire electric discharge machining, collectively called as the colloidal solution of nanoparticles. A heat pipe is a simple heat transfer device that can transport large quantities of heat with a very small difference in temperature between the hot ends to the other end. In this case study, the concept of the evaporation of the working fluid inside the heat pipe is used to compare the heat carrying capacity of two heat pipes. The objective of this study is to compare the efficiency between the primary heat pipe with distilled water as the working fluid and the secondary heat pipe with colloidal Nano Fluid, produced as a result from wire electric discharge machining as the working medium. The heat pipe is divided into 2-sample specimen. First specimen of heat pipe using distilled water while the other one used colloidal Nano Fluid. These two heat pipes are built without the mesh wick and are dealing with inclination of angle to see the performance of the heat pipe. Both the heat pipes were built with the total length of 600 mm length and 16 mm diameter using copper as the pipe material. Gravity pumping was used with the inclination angle to pump back the working fluid to the evaporator section. The heat pipe was positioned at different angles of 0º, 45° and 90° with the horizontal. To achieve the objective of this study, both pipes were studied experimental to find the most efficiency between the primary heat pipe and the secondary heat pipe. The important parameter involves in the case study are the variation of Thermal Resistance and the Overall Heat Transfer Coefficient with the varying heat inputs to the heat pipes. After performing the experiments, the objective of this case study is achieved.

Although indwelling urinary catheterization is a medical intervention with well-defined risks. Despite these known disadvantages, urethral urinary catheterizations are frequently used without an appropriate indication such as acute urinary retention. The prevalence of Bacterial Isolates From Prostatitis patients using indwelling Urinary Catheters was carried out in Umuahia, Abia State using culture technique. 800 patients were examined for prostate specific antigens (PSA) using quantitative and qualitative tests, culture and antibiotic susceptibility tests were also done. Out of 800 patients tested for PSA test in Umuahia was 416 (52.0%) and 433 (54.1%) for quantitative and qualitative tests respectively. in Umuahia as 800 urine samples were cultured with 280(50.9%) isolates from uncatheterized patients and 210(84.0%) isolates from catheterized patient. The bacterial isolates from catheterized and uncatheterized patients were Escherichia coli 149 (30.4%), K. pneumoniae 84 (17.1%), S. aureus 105 (21.40%), S. faecalis 61 (12.4%), P. mirabilis 51 (10.4%) and P.aeruginosa 40 (8.7%). Higher bacterial loads were observed in the catheterized patient’s urine than in the uncatheterized patient’s urine. Ceftriaxone, Streptomycin, and Augumentine were the drugs of choice in the sensitivity tests while high antimicrobial resistant rates were observed with Ampiclox, Septrin and Amoxil. Generally, high prevalence rate of PSA and bacterial pathogens were reported in patients of higher age (50 and above years). Increase in age, low socio-economic status and poor environment dwellers were found as demographic risk in aggravating the chance of getting prostatitis in the research areas. This calls for awareness, diagnosis and proper medical checks for men of 50 years and above. This medical check will prevent the chance of developing prostatitis and other complications that may lead to infertility and inability to urinate.

Natarajan suggested and successfully applied the regressed model equation form, LnKP=aLn(10)+bLnT+c/T with a reported deviation of less than 5-percent from the JANAF Thermo-chemical Tables data, to predict the equilibrium constants in terms of pressure and mole concentrations of certain chemical species in chemical reactions, presented in tabular forms, for units in, atm, and mol/cm3, respectively. The attraction of the Natarajan model is the reduced uncertainties, and flexibility of computationally handling and presenting, in an easily analysable way, scaled thermo-chemical dataset, in possible selectivity control applications for real-time transaction response smart chemical sensors (RTTR-SCS). However, some important probable species in high temperature range, 1000 -to- 6000 K, combustion reactions such as, HCO, HO2, HNCO, NCN, NCO, NNH, and OH, were not considered in the Natarajan Tables. This contribution is an extension, and addition to the Natarajan Tables based on regressed data obtained from JANAF 1971 and 1998 Tables. There is indication from analysis, that at JANAF Tables, Log KP, breakaway negative -to- positive sign (or vice versa) transition points, the prediction uncertainties are higher, which hints possibly at temperature validity and avoidance limits in applications.

Color strength is dominating fact which determine the quality of dyed fabrics and it depends on different dyeing parameters like as temperature, salt, alkali, dye %. Effect of dyeing process parameters on color strength of rayon polyester blended fabric was studied in this research. By varying temperature, pH, dispersing agent, salt and soda the color strength of dyed fabric were investigated. Solid dyeing effect was developed by dyeing both part of blended fabric. Dyeing of polyester part was recommended with temperature 130°C depending on color strength value. Highest color strength value was observed for dyeing with reactive dyes at temperature 70-80°C using salt 60-80 g/l and soda 15-25 g/l. Different types of soda and alkali were used for dyeing of rayon part and measure their effect on color strength.

This research focuses on the use of accelerated curing of concrete by means of warm water at 35°C. The experiment was checked regularly to maintain same temperature all through thetime of heating.The workability and compressive strength properties of the concrete produced from mix ratio 1:2:4 have been ascertained. Compressive strength test on the hardened concrete at 7,14,21 and 28 days were as well obtained. From the results, the value obtained for the slump test corresponds to the design range of 25mm-100mm. The slump increased from 60mm in sample A to 65mm in samples B and C and then decreased to 50mm in samples D and E this can be associated with the variation in temperature as well as hydration. Furthermore, the hardened concrete was found to have lost some weight after curing, this is because weight loss is accompanied by strength gain. A relationship between the concrete cubes cured under 1-day in the accelerated condition and normal concrete at 28 days was established so that the 28-day strength can be predicted from the accelerated. The relationship has been found mathematically as: R28 = Ra [0.8026 ± 0.0001] -1. Where R28 = 28-day strength andRa = accelerated strength. Optimal temperatures used in this research work is 35 ± 2°C. The 35°C used is optimal and help the hydration products, calcium silicate hydrates to settle suitably. Problem of possible compressive strength losses due to induced thermal stresses were taken care of by allowing a delay period equivalently equal to the initial setting time to elapse, so that concrete gained some tensile strength before curing commenced.

In this research work, formulation of emulsion paint from pure polyvinyl acetate (PVA) and polyvinyl acetate/soybeans oil (SBO) copolymer (PVA/SBO) resins (binder) was successfully carried out from 0 to 35 % concentrations. However, properties such as viscosity increases from (0.92 to 2.7 m2/s), density also decreases from (1.28 to 1.06 g/cm3), pH, flexibility, tackiness, stability and drying time, adhesion, resistance to blistering and chemical resistance of the formulated and commercial paint was carried out which shows encouraging (good) results. The results obtained when compared with the values of the commercial paint are within the acceptable level in the coating industry. The results have demonstrated the development of emulsion paint from PVA/SBO resin, this emulsion paint when fully harnessed will reduce the over dependence on the synthetic oil based paints and hence a reduction in volatile organic compounds (VOC) emission into our environment which will in turn provide a healthier environment.

The traditional aroma of soybean daddawa has not been perfectly replicated through controlled fermentation which made use of only Bacillus species. The present study therefore focused on selection of suitable starter cultures for the controlled fermentation of soybean daddawa with primary focus on using Bacillus species, heterofermentative Lactic acid bacteria (LAB) and Staphylococcus strains. The effect of mono and mixed starter cultures on the sensorial qualities of the produced soybean daddawa was also evaluated. A total of sixty-six bacteria strains isolated from spontaneously fermented soybean daddawa obtained from four sites were evaluated for their amylolytic, proteolytic, heterofermentation and coagulase activities. Based on the result of the screening exercise Bacillus subtilis LB3, Staphylococcus xylosus SAU3 and Leuconostoc mesenteroides ssp cremoris LAB5 were selected for controlled fermentation studies. The result of the antagonistic test between the selected microorganisms showed that the microorganisms were not antagonistic to one another. The enzyme profiles of the selected organisms indicated wide arrays of eleven enzymes. Prominent among these werealkaline and acid phosphatase, leucine arylamidase, trypsin, Naphthol-AS-B1-phosphohydrolase, valine arylamidase, α-chymotrypsin and α-glucosidase and β-galactosidase activities. The overall acceptability of soybean daddawa produced using the three starter bacteria was rated next best to naturally fermented soybean daddawa. This holds a great promise for subsequent industrialization of soybean daddawa production as natural fermentation of soybean daddawa is now nearly replicated in a controlled setting.

Malaria is a leading cause of death in most developing countries. It is responsible for about 300 million clinical cases and 1-2 million deaths annually. The plant Ficus platyphylla is a deciduous plant that is used mostly in the northern part of Nigeria for the treatment of malaria and other illnesses. This study was aimed at investigating the antiplasmodial activity of partially purified leaf extract of F. platyphylla Del in mice. Safe dose determination was carried out to determine the LD50 of the plant extract. For the curative study, twenty one mice were divided into seven (7) groups with five mice in each group. Groups 1, 2, 3, and 4 were administered 600mg/kg body weight of each of the four fractions obtained from the partially purified leaf extract while groups 5 and 6 were administered 50mg/kgbw of artesunate and 0.2ml Normal saline respectively. Group 7 was left untreated. Treatment continued for five days and the level of parasitemia in the blood was determined and the body weight, Packed Cell Volume (PCV) and survival time were also evaluated. Acute oral toxicity of the crude plant extract indicates safety of the plant extract at all doses tested. It was also observed from the study that all fractions show remarkable inhibitory activities against malaria parasite compared to the control groups. There was a significant difference (p<0.05) in the PCV of the treated groups when compared to the control. Only few of the animals in all the treated groups survived beyond day 30 of the experiment. It can be deduced that the partially purified leaf extracts of F. platyphylla possessed antiplasmodial activity thus, indicating its potential as an antimalarial.

The impact of spent petroleum products (diesel and engine oil) discharge from generating plant on soil properties and heavy metal concentrations within the University of Calabar, Nigeria was investigated. Twelve composite soil samples (0-30 cm) were collected from four generating plants within the University. The soil texture irrespective of sampling point was sandy loam. The soil pH ranged from 6.5 to 7.3 in all the locations. The soil organic carbon and total nitrogen were more at point of discharge (POD) i.e. contaminated sites than the uncontaminated while phosphorus content was the reverse. The concentrations of Cd, Pb, Fe, Mn, Cu and Zn ranged from 3.08 - 4.60, 216.00 - 242.75, 322.20 - 517.02, 200.67 - 284.01, 49.99 - 58.27 and 103.67 - 150.67mgkg-1 at POD, respectively. The contamination/pollution index (MPI) classifies the soils at POD as being excessively polluted with Cd and Zn, severely polluted with Mn and Cu and moderately polluted with Pb and Fe. It is therefore recommended that the discharge of petroleum products from generating plant should be avoided in order to reduce the negative impact on the soil ecosystem and human health.

Educating future health care practitioners is an important role for universities. Optimal learning environments consider how students learn and utilize various teaching methods to tailor curriculum delivery to match specified student learning preferences. Individualshave a preferential focus on different types of information, the different ways of perceiving the information, and the understanding of information. The grouping of students according to a number of scales and questionnaires pertaining to the ways they receive and process information is defined as a learning style model. Learning Styles is chiefly associated with Honey and Mumford who spent a considerable amount of time on the topic and coming up with the Learning Styles questionnaire in 1982. The study was a descriptive cross-sectional design. Purposive sampling was used. The study site was in the Kenya Medical Training College-Nairobi campus during the 2015/2016 year of study. A questionnaire composed of two questionnaires by Honey and Mumford (1982) and Neil Fleming (1987) was used. Statistical Program for Social Scientists (SPSS) v.25 was used to analyze the data collected. 124 responses were acquired majority being male 58.06%. First years were the majority 37.1%. Reflectors were the bulk of the population 66.1% and pragmatists the least 7.3%. First years were majorly 73.9% Reflectors with high significance relationship between the year of study and the learning philosophy (ꭓ2= 4.987, df=6 P=0.002). Reflectors stood out as the majority in all the learning styles, 47% of the respondents were Reflectors and Kinesthetic learners. On VARK majority of the students applied Kinesthetic as moe of learning. A significant association between the year of study and the learning philosophies (ꭓ2=6.56, p<0.0001 df=6). Similarly, there was a significant association between the gender of the participants and the learning styles (ꭓ2=3.56, p<0.001 df=6). It can be recommended that the learning preferences of physiotherapy students should be verified prior to the start of their academic tasks by using the VARK questionnaire and the categorization of learning into the philosophical classes. The preferred learning styles of medical students in the present study were aural and reading/writing styles. I would like to extend my gratitude to the students who participated in this study and completed the questionnaires

The objective of the study was to examine pig business in Kaduna State, Nigeria. Multi stage and purposive sampling techniques were used in selecting a random sample size of hundred (100) pig producers for the research. A structured questionnaire was administered on respondents for information. Data were analysed using descriptive statistics such as percentages, frequency, gross margin model and Cobb Douglas production function. The result revealed that majority (57%) of respondents involved in pig business were females.Pig business was profitable with a return per naira invested of 0.69 kobo and gross margin of N8,426.30 per pig. The t- test confirmed that pig business was profitable and significant at 1% level. Pig business operated at stage ii of the production function, indicating a decreasing return to scale with summed coefficients of 0.823. The study recommended that government should intervene through the provision of extension services and access to credit facilities.
