Adejuyigbe S.B.
Journal of Engineering and Applied Sciences , 2012,
Abstract: This study looked at Industrial Automation in Ghanaian Industries using the Kumasi Metropolis as a case study. It was aimed at investigating the various types of industries in the metropolis in terms of operational conditions. Evaluating which ones was Manually Operated, Computer- Aided, Semi-Automated or Fully Automated. And also evaluate the effects of Automation on the companies that are automated and finding out ways of improving the manually operated companies. This was achieved by the administration of questionnaires to ten companies in the metropolis. All the information was compiled and the necessary deductions were made. It was however realized from the research that Ghana need a lot of improvement in the area of automation since about 70%of the companies were manually operated, about 20% used semi-automated process and only about 10% are fully automated. Therefore it can be concluded that the companies in Ghana were not enjoying the benefits of automation such as reduction in scrap, reduced labour cost etc. as witnessed in advanced countries. Hence the clarion call in this study that Manufacturing Industries in Ghana should embrace automation so as to enjoy the benefits of automation to its fullest as witnessed in the developed countries of the world.
Computer Aided Manufacturing of Sand Casting Products
S.B. Adejuyigbe
Journal of Engineering and Applied Sciences , 2012,
Abstract: The research investigates the traditional methods of sand casting processes. It also develops computer software called EASYCAST for manufacturing process of sand casting using computer as an aid. A suitable computer programme was developed to implement the algorithm for the computerization process. A life (two practical) components or products was used to test the validity of the computer software developed. In carrying out this research it was observed that some important facilities to achieve a perfect casting were not available. The manual ways of making pattern and mould which was prominent in the developing world for casting (which was not following the full theory as presented in this research) make the work difficult to achieve. This explains the reason for not reaching the 100% close accurate result to that of EASYCAST Computer Software Manufacturing Model developed in this study which is theory based.
CAD/CAM in Nigerian Manufacturing Industries: The Case of Nigerian Casting Industries
Adejuyigbe, S.B.
Journal of Engineering and Applied Sciences , 2012,
Abstract: This study discussed the application of Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) in Nigerian Casting Industries. Questionnaires were administered in twelve (12) casting industries visited, in Lagos, Osun and Kogi States.The results of the research shows that 42% of the under study had incorporated CAD/CAM into their casting industries, while about 58% has not incorporated CAD/CAM into their operation. The percentages of the expatriate involved in the casting operation in these industries were examined to have about 13% and also the plant ages were examined. The result of the study shows that the use of Computer as an aid in casting industries has greatly improved the casting operation at all sections/stages of production. It was however discovered that about 71% of Nigeria casting industries are still depending on foreign raw material (software packages) because of insufficient software developers that are very few in our developing society.

African Journal of Paediatric Surgery , 2011,
Abstract: Background: Hirschsprung′s disease (HD) is a common cause of intestinal obstruction in children. Definitive treatments consist of excision of the aganglionic segment and anastomosing the normal colon to the anal remnant. The outcome of this approach in Nigerian children is not known. The aim of this study was to analyze the short to mid-term outcome of children who have undergone the Swenson Procedure (SPT) as a treatment of HD over a period of 10 years. Patients and Methods: The clinical data of biopsy-proven cases of HD managed at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria, between 1998 and 2007 were reviewed. Results: There were 33 children 28 were males and five were females (M 5.6: F = 1). The median age at presentation was eight months (range three days to 11 years). Eighteen (54.5%) patients had primary pull-through without colostomy while 15 (45.5%) patients had a two-staged operation. The operation was carried out at a median age of 14 months with a range of seven weeks to 11 years, four months. Twenty-one (64%) of the patients were older than one year at the time of surgery. The level of aganglionosis was in the recto-sigmoid area in 30 (91%) patients. The commonest post-SPT complication was intestinal obstruction from adhesions. Bowel opening varied from once daily to eight times daily, median thrice daily. Conclusion: The Swenson′s Procedure is an effective procedure in the treatment of HD in children in Ile Ife, Nigeria.
Management of ambiguous genitalia in ile ife, Nigeria: Challenges and outcome
Sowande Oludayo,Adejuyigbe Olusanya
African Journal of Paediatric Surgery , 2009,
Abstract: Background: Ambiguous genitalia are a major cause of parental anxiety and can create social problems if not properly managed. Diagnosis and management can however be challenging. The aim of this study is to highlight some of the challenges in management of ambiguous genitalia in our environment. Patients and Methods: All cases of ambiguous genitalia managed at the Paediatric surgical unit of the Obafemi Awolowo University Teaching hospital, Ile Ife, Nigeria, between January 1993 and October 2007 were analysed for age, sex at presentation, investigation modality, and final sex of rearing and outcome of surgery. Result: Nine patients had surgical reconstruction for ambiguous genitalia during the study period. Their age ranges from 5 weeks to 19 years at presentation. The causes of genital ambiguity in the patients was congenital adrenal hyperplasia (CAH) in 6, true hermaphroditism in 2 and male pseudo-hermaphroditism in 1. Seven patients were reconstructed as females while 2 were raised as males. Change of sex of raring was necessary in 2 patients. Conclusion: The diagnosis and management of ambiguous genitalia is a challenging problem in our environment. Early presentation and treatment is necessary to avoid psychological and social embarrassment.
Posterior sagittal approach in complicated Swenson′s pull-through
Sowande O,Adejuyigbe O
Journal of Indian Association of Pediatric Surgeons , 2008,
Abstract: Context: Swenson′s pull-through is one of the standard operations for the treatment of children with Hirschsprung′s disease. Complications arising from the operation are difficult to treat because of fibrosis in the pelvis. The posterior sagittal approach may be a safer alternative. Aims: The aim of this paper is to highlight our experience with the use of the posterior sagittal trans-sphincteric approach to treat unusual complications of Swenson′s pull-through. Settings and Design: A retrospective study of four patients who had posterior sagittal repair of their complications of Swenson pull-through at the Obafemi Awolowo University Teaching Hospital, Ile Ife, Nigeria. Materials and Methods: Four cases of Hirschsprung′s disease that developed post-Swenson pull-through complications are presented. There were three males and one female. Their age ranged between 10 months and 15 years. The patients had rectovaginal fistula, rectourethral fistula, high trans-sphincteric fistula-in-ano and complete anastomotic disruption. Result: All the patients were successfully treated using the posterior sagittal approach. The approach was used twice in one patient without significant sequelae. The three patients were old enough to be assessed and had a Kelly score of 4-6 at follow-up. Conclusion: The posterior sagittal technique offers a safe approach to treat the complications of Swenson pull-through.
Minimax Multivariate Control Chart Using a Polynomial Function  [PDF]
Johnson Ademola Adewara, Kayode Samuel Adekeye, Osebekwin Ebenezer Asiribo, Samuel Babatope Adejuyigbe
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.212219
Abstract: Minimax control chart uses the joint probability distribution of the maximum and minimum standardized sample means to obtain the control limits for monitoring purpose. However, the derivation of the joint probability distribution needed to obtain the minimax control limits is complex. In this paper the multivariate normal distribution is integrated numerically using Simpson’s one third rule to obtain a non-linear polynomial (NLP) function. This NLP function is then substituted and solved numerically using Newton Raphson method to obtain the control limits for the minimax control chart. The approach helps to overcome the problem of obtaining the joint probability distribution needed for estimating the control limits of both the maximum and the minimum statistic for monitoring multivariate process.
A survey of gastrointestinal nematodes in soil samples in Ibadan, Nigeria
CA Agunloye, JO Esan, RO Adejuyigbe
Nigerian Veterinary Journal , 2002,
Abstract: A survey was conducted to determine the level of soil contamination by gastrointestinal nematodes in high and low density areas of Ibadan Nigeria. This was to determine the comparative level of soil contamination by these helminthes. Out of the 60 top and deep soil samples collected from high-density areas, 12(20%) were positive for various pathogenic gastrointestinal nematodes. They include Ascaris sp., Toxocara canis, Trichuris trichiura, Strongyloides stercoralis, Ancylostoma sp. and Trichostrongylus colubriformis. Of the 60 soil samples collected from low density areas 9(15%) were positive for Ascaris sp, Dictyocaulus filaria and T. trichiura. However, their infection rates were not significantly different in the two study areas (P> 0.05 Chi square test). It is concluded that soil may play an important role in the epidemiology of these infections in man and animals. Nigerian Veterinary Journal Vol.23(1) 2002: 75-78
