Item Open Access Reduction in annualar pressure loss by mud rheology control -a means of mud pump pressure control optimization: A case study of Niger Delta well(International Knowledge Press, 2016-02-18) Onugha, Ifeyinwa N.; Igwilo, Kevin C.; Duru, Ugochukwu I.This paper proposes two linear mathematical models for the reduction of annular pressure loss in a Niger Delta well- X, so that mud pump pressure is optimized. Data related to mud rheology, mud pump pressure, drill cuttings and the well geometry is available for well X which has already been drilled. The first linear model involves the reduction in pressure drop in the drill collar-casing annulus and the second linear model involves the reduction in pressure drop in the drill pipe-casing annulus. These models express reduced or critical annular pressure drops in terms of two mud rheological parameters- the yield point and plastic viscosity. For combined annular drill collar and drill pipe pressure loss, this paper proposes that the two linear mathematical models can be solved simultaneously to obtain optimum yield point and plastic viscosity of the drilling mud system to be employed for hole cleaning in the combined drill collar-casing and drill pipe-casing annulus. The Herschel Bulkley model is employed as the rheological model that represents the properties of the drilling mud system analyzed and is generated for eight rheological cases each of the drill collar and drill pipe annular hole cleaning as well as two cases of the combined drill collar and drill pipe annular hole cleaning.Item Open Access Modification of waste tire pyrolytic oil as base fluid for synthetic lube oil blending and production: Waste tire utilization approach. Journal of Material Cycles and Waste Management (Online First)(Springer, 2020) Okoro, Emmanuel E.; Erivona, Nehemiah O.; Sanni, Samuel E.; Orodu, Kale B.; Igwilo, Kevin C.This study provides an environmentally friendly process for the production of waste tire pyrolytic oil from fast pyrolysis for use in lube oil production. The produced waste tire pyrolytic oil was further distilled to provide an almost pure base fuid for production of lube oil. The distilled pyrolytic oil was further transformed to lube oil via polyol synthesis. Characterization of the distilled pyrolytic oil from waste tire pyrolysis shows that the oil after distillation contained 2.04 g/100 g of Aliphatic hydrocarbons, 1.96 g/100 g of naphthalene, and 5.99 g/100 g of parafn. The synthetic base fuid was blended with additive to obtain the desired lube oil. Based on the results obtained, the properties of the produced lubricant fall within the accept able criteria for standard lube oils/commercial lubricants. Six diferent blends (A–F) were produced using varied percentages of the selected additives and the base fuid, however, sample C gave the best lube oil blend considering its average density (0.97 kg/L), average viscosity which compares favourably with ISO viscosity (68 mm2/s) of class 68 oil at 40 °C with a fash point above 200 °CItem Open Access A review of hydraulic work-over unit (HWU) application for well repairs in Nigeria(U. P., 2014) Ohia, N.; Anayadiegwu, C.; Igwilo, K.As part of efforts to encourage indigenous/local content in the area of work-over, re-completion and abandonment in Nigeria, Work over campaigns using a self elevating work-over platform (SEWOP) and a hydraulic work-over (HWU) unit was introduced in the year 2001. These projects provided an opportunity for Nigerian indigenous contractors to work closely with multinational companies with a view to develop expertise. Upon this platform was the services of the HWU introduced to the Nigerian oil & gas industry (for work-over, re-completion, well testing and abandonment) introduced to the Nigerian oil & gas industry. The initial objective of these campaigns was to equip older wells in the land and swamp locations with Surface Control Sub-surface Safety Valves (SCSSV) and top packers, in accordance with company’s well integrity management policy. This policy also required that some of these wells be abandoned to ensure the safety of the environment. It also presented an opportunity to carry out other well repairs and to install gas lift mandrels as the case may be. The projects’ priority factor (if compared with other income generating projects within the system) was low, especially for the abandonments. Hence, recognizing that funds are limited, the services of the HWU provided versatility and cost effectiveness .Between August 2001 and March 2006, a total of about fifty three wells were successfully worked on across the Niger Delta region in land, swamp and offshore locations. These series of operations were not without challenges considering the peculiar nature of the Niger Delta terrain in terms of operation and service delivery. Within the period mentioned above, a “learning curve” was developed for hydraulic workover that can be useful to operators in the oil and gas industry. In this paper, efforts have been made to describe this “curve” for the purposes of improving business results. This paper will also review significant cost saving achievements and challenges that were encountered during the entire period under review.Item Open Access Effects of chemical surface modifications on combretumdolichopetalum fiber for sustainable applications(U. P., 2016-01) Walter, P. E.; Azeez, T. O.; Onukwuli, O. D.; Atuanya, C. U.The need to minimize the environmental effect posed by Combretum dolichopetalum(C. dolichopetalum) fiber and its effective use in polymer applications necessitated this study. Effect of chemical surface treatments onC. dolichopetalum fiberfor sustainable applications was aimed to be investigated. Retting method was employed for extraction of C. dolichopetalum fiber and the proximate contents were determined using gravimetric analysis. The fibers were mercerized and acetylated separately by 0 – 15 % within time intervals of 10 – 50 minutes and 30 – 150 minutes respectively at room temperature. The tensile strength in accordance with ASTM standards, aspect ratio, water absorption and microstructural analysis were studied with aids of scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR). The result shows that the fibers contain 59.22 % cellulose, 20.30 % hemicelluloses, 2.40 % lignin, 9.32 % pectin, 4.08 % moisture and 2.26 % wax. The tensile strength of the mercerized and acetylated fibers increased by 877.58 % and 601.73 % of the unmodified fibers at 6 and 12 % concentration for 30 minutes due to increased aspect ratio with reduced density and water adsorption. SEM and FTIR studies revealed changes in surface topography and surface chemistry of the treated fibers.Item Open Access Mercerized milletia sp fiber epoxy composites: Fiber loading, aspect ratio and mechanical properties(U. P., 2018-06) Uzondu, Francis Nnamuzie; Onukwuli, Dominic Okechukwu; Azeez, Taofik Oladimeji; Osoka, C. Emmanuel; Obibuenyi, John IfeanyiThe fiber loading capacity and poor adhesion between fibers and matrix remains an area of concern in fiber polymer composites. The fiber loading capacity and aspect ratio of mercerized milletia sp fiber on mechanical properties (tensile strength, tensile modulus, tensile toughness, elongation, flexural and impact strength) of Milletia sp fiber epoxy composites was investigated. Milletia sp fiber was extracted using water retting approach. The extracted fiber was mercerized at optimum treatment conditions of 5.84 wt% NaOH and 42.58mins. The epoxy composite samples were prepared using hand layup method for epoxy 103 and amine hardner in a ratio 2: 1 and commingled with untreated and treated fiber, respectively, at optimum treatment conditions. The fiber loading of 10 – 50 wt% and aspect ratio of 42.68 – 213.38 mm/mm were used. The mechanical properties of mercerized milletia sp fiber epoxy composite were determined and optimized using RSM of MATLAB statistical tool box. The tensile strength, tensile modulus, toughness, elongation, flexural strength and impact strength for epoxy resin was 44.2 MPa, 1.9716 GPa, 0.8177 MPa, 3.1%, 85.4 MPa and 360 Kj/m2, respectively. At optimum aspect ratio and fiber loading, the mercerized milletia sp fiber increased the tensile strength, tensile modulus, toughness, elongation, flexural strength and impact strength of the epoxy resin by 46.38, 77.75, 97.99, 18.81, 125.06 and 217.78%, respectively. Thus, mercerized Milletia sp fiber enhanced the mechanical properties of epoxy composites.Item Open Access Optimization and characterization of the properties of treated avocado wood flour-linear low density polyethylene composites(Elsevier B.V. on behalf of Faculty of Engineering, Alexandria University, 2019) Government, Rabboni Mike; Onukwuli, Okechukwu Dominic; Azeez, Taofik OladimejiAbstract The research was carried out to investigate the optimization of surface modification for avocado wood flour (ACWF) and the characterization of the treated and untreated of avocado wood flour–linear low density polyethylene composite (ACWF-LLDPE). The variation of treated filler on the mechanical and water sorption properties was investigated. The untreated and treated ACWF-LLDPE composite was characterized using scanning electron microscopy (SEM) and Fourier transform infrared (FTIR). Central Composite design of response surface model (RSM) was used to forecast the mechanical and water sorption properties of ACWF-LLDPE composite. The properties of ACWF-LLDPE composite was statistically analysed and found to be significant. The optimal treatment was particle size of 100 mesh and filler content of 22.97%. At optimum particle size and filler content, the mechanical properties were 24.972 MPa tensile strength (TS), 6.195% elongation (E), 0.863 GP a tensile modulus (TM), 62.664 MPa flexural strength (FS), 0.809 GP a flexural modulus (FM), 699.918 Pa Brinell hardness (BH), and 91.619 kJ/m2 impact strength (IM). The corresponding water sorption (WS) at this condition was 3.338%.Item Open Access Effect of mahogany filler on mechanical properties of reinforced polyethylene matrix(SAVAP International, 2013-07) Olaitan, S. A.; Azeez, T. O.; Atuanya, C. U.; Onukwuli, O. D.; Officha, M. C.; Menkiti, M. C.The effect of mahogany filler as an agricultural waste material used in thermoplastic polymer composite was investigated. Polyethylene (PE), as the matrix, and mahogany sawdust, as the filler, were prepared in five levels of filler loading (10, 20, 25, 30, and 35 wt %) to form thermoplastic composites.Two forms of composite samples were prepared with a recycled polyethylene and mahogany wood filler called recycled polyethylene (RPE) composite and 20 percent of virgin polyethylene with recycled polyethylene wood filler called virgin polyethylene recycled polyethylene (VRPE)composite and their mechanical properties were studied. Test results show that the tensile strengths, tensile modulus, flexural strengths, flexural modulus and hardness properties increased while impact strength, decreased with increase in filler loading for the mixed polyethylene composites but tensile strength of there cycled polyethylene composite decreased with increased filler loading. The appreciable improvement on the tensile strength indicates that mahogany can be used as a reinforced material of the mixed polyethylene composite. Again the presence of 20 percent of virgin PE has significant effects (p < 0.05) on mechanical properties of the mahogany filler – recycled polyethylene composite.Item Open Access Effects of antioxidants on the oxidative stability of vegetable oil at elevated temperature(Center for Promoting Ideas, USA, 2013-05) Azeez, Oladimeji T.; Ejeta, Kennedy O.; Ehigiator, O. Frank; Nwakamma, E. GeraldUnstable nature of vegetable oil posed serious health risk to humans. The oxidative stability of vegetable oils (Palm Olein, Soyabean Oil and Linseed Oil) with direct incorporation of antioxidants (tertiary butyl hydroxoquinone (TBHQ), butylated hydroxyl toluene (BHT) and mixed (TBHQ and BHT) at room temperature and 700C for 168 hours was aimed to be investigated. Peroxide value was determined and the oxidative stability was evaluated. TBHQ had significant effect on the oxidative stability of palm olein at 700C while (TBHQ and BHT) had synergetic effect on stability of Soya bean oil at room temperature and Linseed oil at 700C.Item Open Access Exercise and pregnancy: A review study(U. P., 2010) Lamina, S.; Musa, D. I.; Hanif, S.; Azeez, T. O.In recent times, researchers, exercise advocates and other professional experts in women’s health are agitating for women participation in exercise programme. Reasons for this advocacy might not be unconnected to the fact that the benefits of exercise for women far outweigh the complications particularly in pregnancy. This paper review significance of exercises during pregnancy. The review revealed that it is unrealistic for pregnant women to participate in vigorous physical activity, but could benefit from antenatal physiotherapy. It is also apparent that female athletes tend to have fever pregnancy and child birth related complications than do normal non athletic women. This is suggestive that women should be physically active but pregnant women continue to participate in activities which they are familiar with, while regular participation of women of reproductive age in exercise and sports is highly encouraged.Item Open Access Ergogenic controversies of socio-cultural African herbs: A review study on khat (CATHA EDULIS) and kolanut (Cola Spp)(U. P., 2010) Lamina, S.; Azeez, T. O.; Subramanian, M.; Ayana, A. M.Khat and kola nut, are highly controversial ergogenic herbs indigenous to Africa and in the countries around the Red Sea. The spectrum of khat actions has been postulated to lie between amphetamines and caffeine while kola nut active chemical is caffeine. Therefore, khat and kola nuts and their principal active constituents (cathinone, cathine and caffeine respectively) are categorized as stimulants. The chewing of khat leaves and kola nuts has a deep rooted religious and socio- cultural tradition in Africa. Ironically, the World Antidoping Agency and the International Olympic Committee have placed a limit to cathine usage in sports. Caffeine, though not presently in the list of banned substances, but was previously banned, unbanned and restricted before 2004. Reasons for the partial ban and unban of cathine and caffeine respectively seem unclear and ambiguous. It is also confusing and worrisome if, the ethical line of cheating in sport is being scrutinized more carefully, or weather a cultural incident of khat and kola nut chewing is being handled appropriately. Before a conclusive statement could be made on the ergogenic status of both herbs, there is a need for joint extensive studies and international conference of stakeholders.Item Open Access Nutritional evaluation of medicinal cnidoscolus aconitifolius (Chaya) leaves used in Nigeria(ABC Publishers Inc., 2013) Iwuji, S.; Nwafor, A.; Azeez, T. O.; Nwosu, E. C.; Egwurugwu, J.; Danladi, N. B.Evaluation of the nutritional content of edible plants is currently essential for safety. This work assessed the proximate and mineral composition of the leaves of Chaya plant (Cnidoscolus aconitifolius) commonly known as ‘hospital is too far’ and consumed in Niger Delta, Nigeria for medicinal and nutritional purposes. The study showed that the dried leaves of the plant contain 47.03 ±1.02% of nitrogen free extract; 33.04± 3.14% of crude fibre; 7.03±0.23% of crude fat; 4.03±0.67% of crude protein, while moisture and ash made up 6.10±1.10% and 3.04±0.32%, respectively. A gram of the dried leaves yielded (in mg) 10±1.2, 20±1.6, 0.01±0.1, 100±5.3, 85±4.32, 18±2.1 and 50±2.3 of Iron, Phosphorus, Sodium, Potassium, Magnesium, Manganese and Calcium, respectively. The energy yield was 258±4.5kcal/100 mg. These results suggested the comparative richness of the leaves in fibre, high nitrogen free extract (carbohydrate) and essential minerals to prevent nutritional and electrolyte deficiency disorders among the consumers.Item Open Access Nutritional and electrolyte values of cnidoscolus aconitifolius (Chaya) leaves consumed in Niger Delta, Nigeria(U. P., 2013) Iwuji, Samuel Chidi; Nwafor, Arthur; Azeez, Taofik Oladimeji; Nwosu, Emmanuel Chibuike; Nwaokoro, Joakin Chidozie; Egwurugwu, Jude; Danladi, Nygan BalaEvaluation of the nutritive and electrolyte values of edible plants is currently essential for human nutrition and safety. This work assessed the proximate and mineral composition of the leaves of Chaya plant (Cnidoscolus aconitifolius) consumed in Niger Delta Nigeria for medicinal and nutritional purposes. Chaya is commonly known in this southern area of Nigeria as ‘hospital is too far’ or ‘ogwu obala’. The study showed that the dried leaves of the plant contain 47.03 ±1.02% of nitrogen free extract; 33.04± 3.14% of crude fibre; 7.03±0.23% of crude fat; 4.03±0.67% of crude protein, while moisture and ash made up 6.10±1.10% and 3.04±0.32%, respectively. A gram of the dried leaves yielded (in mg) 10±1.2, 20±1.6, 0.01±0.1, 100±5.3, 85±4.32, 18±2.1 and 50±2.3 of Iron, Phosphorus, Sodium, Potassium, Magnesium, Manganese and Calcium, respectively. The energy yield of the leaves was 258±4.5kcal/100 mg. These results suggested the comparative richness of the leaves in fibre, high nitrogen free extract (carbohydrate) and essential minerals. Properly prepared leaves are therefore recommended for daily consumption in order to supplement the recommended daily intake of nutrients and minerals and hence prevent nutritional and electrolyte deficiency disorders.Item Open Access Impact of nanotechnology in Nigeria: A short survey(MedCrave, 2017-05-15) Ejeta, K. O.; Dolor, G. A.; Ndubuka, G. I.; Nkuma-Udah, K. I.; Azeez, T. O.; Odugwu, O.Nanotechnology, one of the foremost alternative modern technologies of the twenty-first century offers enormous benefits and opportunities through synthesis, characterization and fabrication of quite vast number of nanomaterial to solve societal immediate problems. Structured questionnaires were administered to three different industries in each of the six geo-political zones in Nigeria, a Country located in West Africa bordering the gulf of Guinea, Niger and Chad (North), Benin (West) and Cameroon (East) to determine the impact of nanotechnology. The data emanating from this study were analyzed using multiple regression analysis, correlation analysis, analysis of variance (ANOVA) [1] and likert 5 scales with T-test utilized in determining levels of significance. The findings are reported and discussed.Item Open Access Nanobiosensors: Applications in biomedical technology(IOP Publishing, 2020) Banigo, A. T.; Azeez, T. O.; Ejeta, K. O.; Lateef, A.; Ajuogu, E.Biosensor devices are composed of bioreceptor, transducer and detector that detect and aid in measuring parameters of some primary metabolites, immunological molecules and many more materials. These devices are of various types including piezoelectric which exhibit high efficiency based on sensitivity, response time, selectivity and linearity. Currently, newly developed nanobiosensors help in transduction and are employed to sense biomolecules bearing high sensitivity. Nanobiosensors also could be homogeneous or heterogeneous in nature and equally function in sensing mechanism of the biosensing technology. Thus, different nanobiosensors are greatly utilized to reduce poison in products, disease diagnostics and in many biomedical applications. Based on all these factors and the positive impact of using these devices; nanobiosensor types, applications, challenges and preferred solution in biomedical technology were considered and discussed in this work.Item Open Access The impact of mentoring programs for sustainable career development and work/life balance in Biomedical Engineering profession - Short communication(U. P., 2019) Banigo, Alma Tamunonengiofori; Iwuji, Samuel Chidi; Ezelote, Judith Chinelo; Azeez, Taofik OladimejiThe socio-economic, technological and emotional imbalance remains an issue of individual growth in career development and work-life balance. The impact of mentoring programs for sustainable career development and work and lifestyle balance in biomedical professions was examined. Career development was studied using self-assessment, career awareness, performance, skill acquisition, goal setting and work-life style balance. Career development can be achieved with pleasure if the essential routes were addressed by the parties involved in mentoring programs. Proffered solution of organizational support, social support, use of modern facilities and self-assessment were recommended as tools for mentoring programs that reduced pain, depression, friction and wear, and emotional stress of mentors and mentees. Thus, provide an outstanding strength of social, economic, technological and emotional output as well as good healthy conditions for career development and stable work-lifestyle to achieve a set goal and target in biomedical engineering profession based on action plans.Item Open Access Tensile response of treated cissus populnea fibers(U. P., 2018-01) Azeez, T. O.; Onukwuli, O. D.Improvement and effectiveness of polymers through reinforced materials coupled with environmental nuisance of the Cissus populnea fiber remains an area of concern. Tensile responses of chemically treated C. populnea fibers were investigated. Gravimetric analysis was used to determine the composition of C. populnea fibers. Sodium hydroxide (NaOH), acetic anhydride (AC) and ethylene diaminetetra-acetic acid (EDTA), respectively, were used for fiber treatment and optimized with variable parameters (concentration and time) using response surface methodology (RSM) with central composite design. Scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) were studied. At optimum treatment conditions, NaOH, AC and EDTA, respectively, increased the tensile strength of C. populnea fiber by 33.49, 274 and 194.52% as well as tensile modulus by 793.43, 20799.43 and 855%. Hence acetic anhydride treatment gave the best tensile properties of C. populnea fibers as corroborated by SEM with EDS. Thus, the effective use of C. populnea fiber in composite applications can be improved by chemical surface modifications.Item Open Access Influence of chemical surface modifications on mechanical properties of combretum dolichopetalum fibre-high density polyethylene (HDPE) composites(U. P., 2018) Azeez, Taofik Oladimeji; Onukwuli, Okechukwu Dominic; Walter, Peter Echeng; Menkiti, Mathew ChukwudiMaximizing the use of natural fibres as ecofriendly materials in polymer composite applications reduces its threat posed to human through increased biomass in the environment. In this study, the effect of chemical surface modifications using acetic anhydride and sodium hydroxide solution on the mechanical properties of Combretum dolichopetalum fibre-HDPE composites was aimed to be investigated. Fibres were treated with 6 % acetic anhydride and 12 % NaOH solutions for 30 minutes at room temperature based on optimum treatment conditions after water retting extraction process, then, the composites were prepared. The mechanical properties (tensile strength, tensile modulus, flexural strength, flexural modulus, hardness and impact strength) of the C. dolichopetalum fibre reinforced HDPE matrix composites and scanning electron microscope analysis were studied. C. dolichopetalum fibre was not only effective as reinforcement of HDPE matrix but mercerization and acetylation of C. dolichopetalum fibre ultimately enhanced the mechanical properties of HDPE composites. Scanning electron microscope analysis revealed that HDPE matrix possess better adhesive interaction with acetylated and mercerized C. dolichopetalum fibre compared with untreated C. dolichopetalum fibre at ultimate tensile strength.Item Open Access Correlates of cardiorespiratory fitness and gait parameters in young undergraduate subjects(U. P., 2010) Azeez, T. O.; Lamina, S.; Iwuji, S. C.Physiological studies of healthy individuals suggested that the pattern of walking influenced the oxygen cost of walking in a given distance. It has also been observed that in pathological states, shorter and frequent steps are common and that this inefficient gait might contribute to exercise limitation. The purpose of the present study was therefore to investigate the corelates of cardiovascular fitness and gait parameters in young undergraduate students. A cross sectional independent group design was used in data collection. Forty subjects with age ranged between 20 and 30 years participated in the study. Subjects’ cardiorespiratory fitness was assessed using the 1.4 miles run; subjects were group into cardiorespiratory fitness category of high and low. Gait parameters (cadence [CD], step time [ST] & gait speed [GS]) were assessed using the paper-and-pencil method. Student t test and Pearson correlation test were used in data analysis. Findings indicates significant increase in the high fit group over low fit group in CD, ST and GS at p<.05. There was a significant positive and negative correlation between VO2max and gait variables respectively: GS (.465), CD (.555) and ST (-.580) at p<.01. The present study concluded that cardiovascular fitness could be a positive factor/marker of qualitative pattern of walking in normal young adult. Future studies investigating the effect of physical training on pattern of walking in the healthy, chronic diseases and the disables are recommended.Item Open Access Optimization of biodegradation of anthracene by corynebacterium sp and psuedomonas putida(U. P., 2015-05) Azeez, Taofik Oladimeji; Owabor, Chiedu Ngozi; Nwakaudu, Madueke Stanley; Usondu, Nnamuzie FrancisThe carcinogenic potential of industrial effluent discharged of anthracene on the ambient environment with contamination to soils and aquifers is not only environmental concern but difficulty in implementation of biodegradation of anthracene due to inability to optimizing the process parameters. The optimization of process parameters for biodegradation of anthracene with the activity of Corynebacterium sp and Pseudomonas putida using response surface methodology was aimed to be investigated. A 23 of full factorial central composite design was employed for developed quadratic polynomial model to achieve optimal performance of the process. Statistically, high correlation coefficient (R2) for quadratic polynomial model for biodegradation of anthracene by activity of Corynebacterium sp 0.9659 (p<0.05)and Pseudomonas putida 0.9939 (p<0.05) were obtained. The optimum conditions for anthracene degradation by Corynebacterium sp were 69.99g/L, 83.20hours and 3.4735vvm with about 98.48 percent of anthracene degraded while Pseudomonas putida were 69.989g/L, 3.58hours and 3.5vvm with 89.51percent of anthracene degraded.Item Open Access Improving the unsaturated polyester matrix through commingled with chemically treat cissus populnea fibers(U. P., 2017) Azeez, Taofik Oladimeji; Onukwuli, Dominic OkechukwuThe extent of improvement of chemically treated Cissus populnea fiber on morphology, mechanical, adhesion, and water sorption behaviors in Cissus populnea fiber/UPE composites was aimed to be investigated. Fibers were treated with sodium hydroxide (NaOH) and sodium lauryl sulphate (SLS), respectively. The composites were prepared by hand laying techniques of treated and untreated fibers with unsaturated polyester matrix (UPE) using response surface methodology with central composites design of DoE software. The mechanical properties (tensile strength, tensile modulus, flexural strength, flexural modulus, hardness and impact strength) were optimized. The interfacial shear stress (IFSS) using fiber pull-out method, scanning electron microscopy (SEM), density, and water sorption behavior using power law with Fickian diffusion law were studied at optimum level. The optimization of mechanical properties as dependent with factors (weight fraction of the fiber and weight fraction of the matrix) using RSM with CCD technique was done to avoid waste of materials and confusion on properties of the composites. Treatment of Cissus populnea fiber with NaOH and SLS, respectively, improved the tensile and flexural properties of the composites. NaOH treatment gave the best tensile strength while best flexural properties was achieved with SLS treatment. SEM images revealed the morphological changes caused by NaOH and SLS, respectively, at optimal composites production to corroborate interfacial adhesive between Cissus populnea fiber and UPE matrix on composite properties. NaOH and SLS treatments, respectively, reduced the water saturation point with less Fickian behaviour and increased water diffusion coefficient of the composite.
