International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.31006
Abstract: United States physician office visits for asthma have increased since 1989, and most of these visits are to primary care physicians. The National Institutes of Health has published guidelines for asthma diagnosis and management, implementation of which is expected to result in improved care and reduced costs. Compliance with asthma guidelines has been suboptimal, especially with spirometry recommendations, and more so in primary care clinics than in specialist clinics. Noncompliance has largely been attributed to physician and patient factors. This paper describes an experience with navigation of health system barriers to implementation of spirometry encountered at three primary care clinics affiliated with an internal medicine residency program. Included are perspectives and priorities of key individuals, systems issues related to institutions, and technical issues pertaining to spirometers. Navigation of ACGME core competencies is discussed.

Abstract:

Incident of water-borne diseases is becoming more rampant in developing countries in the 21st century. This paper examines the contamination levels of some selected wells in Ogbomoso South Local Government Area (LGA), Oyo State, Nigeria. Methodology includes administering of structured questionnaire, field survey/sampling and laboratory analysis. The first set of questionnaires sought information on water sources, quality, supply and treatment. These were administered in 10 selected major locations which included: Ajegunle, Arinkinkin, Arowomole, Caretaker, Esanu-Aje, Ita-Olola, Malete, Oke-Alapata, Ora-Gada and Sunsun. The other set which was administered in 6 randomly selected Health Institutions viz: Oyo State General Hospital, Alaafia Tayo, Oore-Ofe, Bethel, Favour, and Grace Hospitals had questions on health-related issues. Ten (10) wells were randomly selected for sampling, one in each location. Results were compared with WHO’s Drinking Water Standards. Questionnaires revealed that residents depended mostly on wells for water supply; the water quality was low; supply was irregular; quantity was inadequate and boiling was the commonest treatment method. Health Officials established that some residents consumed improperly treated well water and there were some incidences of water-related diseases. Laboratory analyses showed that samples from Ajegumle and Esanu-Aje had colour values above the standard. Also, the pH was observed to vary from slightly acidic to slightly alkaline with values ranging between 6.0 and 8.1. Only Arinkinkin and Ita-Olola areas had

Abstract: Teachers are indispensable within the teaching – learning process. Hence, they constitute a major input in the accomplishment of educational goals and objectives in all nations. In Nigeria, teacher education has been bedeviled with a lot of challenges in the modern day technology of imparting knowledge in the teaching and learning process. Information and Communication Technology (ICT) is relatively a very new development in Nigerian educational system. ICT plays a significant role in teacher education. Hence, the objective of this paper is to discuss the prospects of ICT in teacher education as well as its challenges in E-teaching profession in Nigeria. The findings via descriptive research revealed that many teachers in Nigeria are not using ICT facilities in teaching learning process due to some challenges which include high exorbitant price of ICT facilities, lack of infrastructures in the areas of electricity supply, lack of adequate trained manpower for the development, maintenance and operation of ICT facilities, lack of commitment on the part of government towards the development of ICT, inadequate funding of internet connectivity and lukewarm attitude of many teachers to be computer literate among others. This paper proffers some probable ways of improving ICT in teacher education in Nigeria. It concludes that the importance of ICT in teacher education to improve the quality of teaching and learning process in schools cannot be over-emphasized.

African Journal of Biomedical Research , 2007,
Abstract: Among 504 out-patients (males and females) suffering from various forms of sexually transmitted diseases at special treatment clinic in University College Hospital, Ibadan, 48 (9.5%) of them were found to have Trichomonas viginalis. Trichomoniasis was found to be more prevalent in women (12.5% of 280), thirteen (5.8%) out of the 224 males had trichomoniasis with a high prevalence in the age bracket of 11 – 30 years in both sexes. Large percentage of single women and men investigated (53% and 26% respectively – 79% in all based on isolates) had trichomoniasis. It was discovered that 68.4% of patients infected with trichomoniasis had discharge (vaginal and urethral), 42.1% had pain on passing urine while 10.5% had irritation on passing urine, and also 10.5% had increase frequency. Twenty-two (42%) of 48 patients with T. vaginalis were diagnosed by microscopy of direct wet mount preparation, all the 48 (100%) positive cases were diagnosed by culture. The two media (Trichomonas medium 2 (Oxoid) and NBGS supported the growth of T. vaginalis and they failed to show superiority over each other. (Afr. J. Biomed. Res. 10: 19 – 24, January 2007)

International Journal of Poultry Science , 2012,
Abstract: The relative efficacy of five proprietary vitamin-mineral premixes on performance and carcass characteristics of broiler chickens was undertaken in a trial lasting six weeks at the Teaching and Research Farm, University of Ibadan, Ibadan, Nigeria. A total of two hundred and eighty eight 1-day broiler chicks of Abor acre strain were randomly allotted to six dietary treatments of forty eight chicks per treatment. Each treatment was a triplicate of sixteen chicks per replicate. Six isocaloric and isonitrogenous diets were formulated. Diet 1 (T1) was the control without any premix. Other diets were supplemented appropriately with 0.25% Daramvita (T2), Biorganics (T3), Hinutrients (T4), Optimix (T5) and DSM Nutripoults (T6). The experimental diets were offered to the respective birds with water given ad libitum. The design of the experiment was a completely randomized design. The feed conversion ratio of birds on T3, T4, T5 and T6 were 2.64, 2.58, 2.61 and 2.57 respectively and were significantly different (p<0.05) from those on T1 (3.62) and T2 (3.35). The obtained live, bled and defeathered weights and dressing percentage values of broilers varied significantly (p<0.05) with the type of vitamin-mineral premix used while values of other primal cuts were statistically similar (p>0.05). Performance and carcass indices indicated variable potency and efficacy of the evaluated proprietary vitamin-mineral premixes in Ibadan, Nigeria.

Open Journal of Optimization (OJOp) , 2014, DOI: 10.4236/ojop.2014.34006
Abstract: Fingerprints are a unique feature for identification and verification of humans. The need to optimise several databases for storing the images of fingerprints is a major concerning issue. Several segmentation algorithms have been used in the time past but there are still several challenges facing some current segmentation algorithms like computational efficiency. Another challenge is that segmentation procedure can be impractically slow, or requires extremely large amounts of memory. This paper addresses the challenges by employing watershed flooding algorithm on the fingerprint images so as to optimize the sizes of the databases. A pre-processing plug-in that implements this segmentation process is developed using Java. We showed its effectiveness by testing it on fingerprint image dataset and the entropy showed that the segmented images sizes were reduced.

Abstract:

Sodium borate glasses embedded with silver were made by the melt quenching technique. Glass transition temperature was recorded by thermal analysis of the sample. As made glasses revealed emission in the visible region under nitrogen laser and excimer laser excitations. Heat treatment was used to induce silver metallic particles. Absorption spectra revealed a peak at 417 nm due to surface Plasmon resonance. Particle size was estimated to be 2.6 ± 0.2 nm. Erbium and silver co-doped multielement oxide glasses were made by the melt quenching technique followed by heat treatment to induce nanoparticles. In heat treated samples, Er3+ luminescence increased 4× due to enhanced field in the vicinity of silver particles. Under excimer laser excitation, Er3+ and 2% Ag co-doped glass revealed Er3+ transitions due to enhanced field at the rare-earth ions. Under 795 nm laser excitation Er3+ green upconversion signals are found to be 4× stronger in 2% Ag co-doped, heat treated sample, than the others.

Applied Mathematics (AM) , 2018, DOI: 10.4236/am.2018.93016
Abstract:
In this research article, we investigate the stability of a complex dynamical system involving coupled rigid bodies consisting of three equal masses joined by three rigid rods of equal lengths, hinged at each of their bases. The system is free to oscillate in the vertical plane. We obtained the equation of motion using the generalized coordinates and the Euler-Lagrange equations. We then proceeded to study the stability of the dynamical systems using the Jacobian linearization method and subsequently confirmed our result by phase portrait analysis. Finally, we performed MathCAD simulation of the resulting ordinary differential equations, describing the dynamics of the system and obtained the graphical profiles for each generalized coordinates representing the angles measured with respect to the vertical axis. It is discovered that the coupled rigid pendulum gives rise to irregular oscillations with ever increasing amplitude. Furthermore, the resulting phase portrait analysis depicted spiral sources for each of the oscillating masses showing that the system under investigation is unstable.

African Journal of Clinical and Experimental Microbiology , 2002,
Abstract: An increasing number of babies with conjunctivitis in our center what require an urgent evaluation was observed. To evaluate Chlamydial aetiology of Neonatal conjunctivitis in our environment all babies born in the University of Ilorin Teaching Hospital over a six months period were prospectively screened for Neonatal conjunctivitis using the Center for Disease Control/World Health Organization case definition for Neonatal conjunctivitis. All patients diagnosed to have Neonatal conjunctivitis had laboratory evaluation done to identify the causes. However only those from whom the inclusion bodies of chlamydia were seen got included in this study. An empirical treatment with 10% sodium sulphacetamide eye drops was given to all patients while other additional illnesses identified were managed in a standard way. Clinical re-evaluation was done by 72 hours and 7 days of treatment for clinical cure. A total number of 112 babies developed neonatal conjunctivitis within the study period among the 852 babies screened and chlamydia was seen in 36 (32%). The hospital based incidence for Chlamydial neonatal conjunctivitis was 42 per thousand live births. There was a male preponderance. Gestational Age ranged between 27 weeks and 44 weeks though there were more term babies. Majority were delivered by spontaneous vertex. The Mean Age of on-set of disease was 5 days with a standard deviation of 3.8 days. Premature rupture of fetal membrane occurred in 1 (3%) case. Fifteen (42%) of 36 mothers had antenatal vaginal discharge. All mothers were married. Purulent eye discharge was the commonest clinical presentation and was sometimes unilateral. All babies responded well to treatment. No complication was observed in any baby. It was concluded that chlamydia trachomatis was the leading cause of neonatal conjunctivitis in our environment and the disease is of a remarkable magnitude requiring attention in our sub region. It has similar outlook with those reported from other regions of the World. (Af. J. of Clinical and Experimental Microbiology: 2002 3(2): 69-71)

Abstract: The introduction of information and communication technology (ICT) to education creates new learning paradigms. We are dwelling in a world which technology has reduced to a global village and the breakthrough in technology is underpinning pedagogical submissions. It may become imperative therefore to have a rethinking on how to ameliorate the constraints of second language users through the applications of modern technologies. The interactions between new technology and pedagogical submissions have been found to an extent to be addressing the heterogeneous needs of second language learners and any global discovery which aims at minimizing learners’ constraints is a welcome development in a rapidly changing world of technology. This paper therefore is an overview presentation of how modern technologies can be of assistance to both teachers and students of a second language setting. The rapid growth in ICT experienced by the technologically advanced nations of the world has helped them to overcome some of the barriers in teaching and learning. Applications of modern day’s technologies in the field of teaching and learning can make it possible for teachers, students and others to join communities of people well beyond their immediate environment to critically review, analyze, contribute, criticize and organize issues logically and contextually having professionalism and the transformations of the entire society in view. Now, new technologies such as the reported computer enhancements with new software and networking make it much easier for educators to conquer space and time, with the motive of ameliorating constraints and academic conflicting issues. We can now bring learning to virtually any place on earth anytime for the purpose of achieving the desirable learning outcomes.
