Antibiotic Prophylaxis in Gastro-Intestinal Surgery: An Evaluation of Current Veterinary Practices in Southwest Nigeria
J.F. Akinrinmade,B.O. Oke
International Journal of Animal and Veterinary Advances , 2012,
Abstract: A study on the use of prophylactic antibiotics in gastro-intestinal surgery by veterinary practices in southwest Nigeria was conducted to evaluate current practices using structured questionnaire and a retrospective study of hospital care records. The results indicated that the use of prophylactic antibiotics in surgery was embraced by all practices with Amoxicillin>Oxytetracycline>Ciprofloxacin>Penstrept and Penstrept>Oxytetracycline>Ciprofloxacin and Amoxicillin being the most prescribed antibiotics for general and gastro-intestinal procedures, respectively. Significant number of practices administered antibiotic prophylaxis for a duration of 5 or more days. All practices administered antibiotic prophylaxis post-operatively while 43.75 and 25.00% of practices also gave additional presurgical and peri-surgical doses, respectively. Only few practices (12.5%) insist on pre-surgical laboratory tests with complete blood count being the most requested analysis. Majority of practices have no protocol for aseptic preparation. It is concluded that the current veterinary practices investigated encouraged inappropriate antibiotic prescribing and may portend serious ecologic consequences in patients undergoing GIT surgery.
Exergetic Analysis of Solar Energy drying Systems  [PDF]
B.O. Bolaji
Natural Resources (NR) , 2011, DOI: 10.4236/nr.2011.22012
Abstract: An exergetic analysis of three basic types of solar drying systems is presented. The analysis is used to find the available useful energy and the quality of energy that is obtainable from the dryers. The dryers were installed side by side and tested simultaneously to eliminate influence of solar radiation and environmental changes in comparing their performances. The results obtained show that mixed mode and indirect mode solar dryers are more effective in utilizing the captured energy than direct mode dryer, and mixed mode has a slight edge in superiority over indirect mode system. 78.1% and 77% of energy collected in the mixed mode and indirect mode systems, respectively, were available as useful energy, while direct mode system could only convert 49.3% of collected energy to useful energy. The overall exergetic efficiencies of mixed mode, indirect mode and direct mode systems were found to be 55.2%, 54.5% and 33.4%, respectively.

Journal of Animal and Veterinary Advances , 2012,
Abstract: This study evaluates the immune status of companion dogs in an urban setting in Nigeria using ELISA technique. A total of 630 companion dogs made up of six major breeds were sampled for rabies virus antibodies by the indirect ELISA method. An overall prevalence of 71.4% (52.9±39.5 EU) was observed, with the males having a prevalence of 69.1% compared to 74.0% for females. The mongrels were observed to have the highest prevalence during the Post-Vaccination (PV) periods while the highest antibody titre was obtained 6-9 months PV and the lowest between 9-12 months PV. The comparative prevalence and antibody titres of dogs vaccinated with different commercial vaccines showed no remarkable difference. There was no significance in the mean SP ratio of dogs of different breeds, sexes and commercial antirabies vaccines also in the PV periods. The prevalence indicates a relatively good protection against rabies outbreak and uniform potency of the common antirabies vaccines in use in Nigeria. It also showed that annual booster vaccination should further be enforced as it enhances immune response in the dogs.

Effect of Eggshell Powder on the Stabilizing Potential of Lime on an Expansive Clay Soil
O.O. Amu,A.B. Fajobi,B.O. Oke
Journal of Applied Sciences , 2005,
Abstract: This research was meant to study the effect of Eggshell Powder (ESP) on the stabilizing potential of lime on an expansive clay soil. Tests were carried out to determine the optimal quantity of lime and the optimal percentage of lime-ESP combination; the optimal quantity of lime was gradually replaced with suitable amount of eggshell powder. The lime stabilized and lime-ESP stabilized mixtures were subjected to engineering tests. The optimal percentage of lime-ESP combination was attained at a 4% ESP + 3% lime, which served as a control. Results of the Maximum Dry Density (MDD), California Bearing Ratio (CBR), unconfined compression test and Undrained triaxial shear strength test all indicated that lime stabilization at 7% is better than the combination of 4% ESP + 3% lime.
A Comparative Analysis of Secondary Education in Four Central African Countries (Burundi, Rwanda, Chad and Equatorial Guinea)
B.O. Lawal
The Social Sciences , 2013,
Abstract: Secondary school education in Central African countries has been bedevilled by lot of problems such as low budgeting, incidence of military insurgence and armed struggle among political rivals or due to boundary disputes, political crisis, wide spread of HIV/AIDS, massive death of teachers, students and parents that have contracted diseases. These have increased government`s expenditure on HIV/AIDS prevention and treatment. The above scenario has reduced the capacity of teachers in carrying out effective teaching in secondary schools by creating absenteeism of both teachers and students in schools. The huge expenditure on military insurgence, armed struggle coupled with prevention of HIV/AIDS and preventing political crisis has reduced government expenditure on secondary schools expansion, creation of more schools while the above situation has also created emotional and psychological insecurity to prompt the citizens (teachers, children and parents) in these countries to migrate to other countries to serve as refugee in those host countries. These have created new problems for neighbouring countries, African Union (AU) and the United Nation (UN). This study, therefore, looks into the problems that have militated against secondary school education these Central African countries (in terms of school management, teachers recruitment, students enrolment, financing and funding of school infrastructures, functional strategies, development and instructional measures to curb the situation are recommended.
A Study of Secondary Educational Practices Ethiopia, Uganda,Tanzania, Mainland Zazibar (East Africa)

Pakistan Journal of Social Sciences , 2012,
Abstract: This comparative analysis study is carried out in other to compare and contrast the educational systems of Ethiopia, Uganda and the United Republic of Tanzania with particular focus on their secondary education. For the purpose of this study, the two states making up the Republic of Tanzania-Tanzania Mainland and Zanzibar were treated separately because they provide basic education separately as stated by the Tanzania Republic Minister for Education and Culture, Prof. Juma Kapuya (MP). The study looked into all the facets of the secondary education of the countries studied during the years for which data were available. Different literatures were reviewed on the topic from where relevant data were drawn and analyzed. Thereafter, useful logical conclusions were made. The study revealed that the secondary education of the countries studied and their education systems in general were greatly affected by the civil wars that ravaged these countries for so many years. The governments, however, are not sleeping on their oars. Rather, they are seriously taking measures to improve the standard of education generally and most especially at the basic levels. However, more still needs to be done especially in the area of educational finance and teacher education.

B.O. Bolaji
Journal of Food Technology , 2013,
Abstract: A box-type absorber solar air collector was designed for use in Ado-Ekiti, Nigeria on latitude 7.5? N and constructed with materials that are readily available in the local market. The performance of solar collector with the dryer was evaluated in the month of August. The results show that high temperature can be achieved in the dryer with the use of the box-type absorber collector. The maximum average temperature obtained (during the daylight) inside the collector and drying chamber were 64.0 and 57.0?C, respectively, while the maximum ambient temperature observed was 33.5?C. The heating temperature inside the dryer was higher than the ambient temperature by an average of 15.3?C (50.7%) throughout the daylight. Comparison between the performance of this system and that of the other systems with different types of absorber shows that this system is more efficient. During the test a maximum collector efficiency of 60.5% was obtained in the system.

Pakistan Journal of Social Sciences , 2012,
Abstract: This study examined Basic Education in Nigeria. The study adopted historical research method in which the investigator relied heavily on primary source of data gathering. In addition, both secondary source of data gathering and structured interviews were used. The study revealed that Basic Education brought about an increase in the pupils enrolment within the period of study. It also showed that the percentage of qualified teachers within the period of study increased. The pupil/teacher ratio in the country is still very high as against the National Policy on Education. The government budget on education is still very low as a result of which Basic Education in the country has not been fully implemented. The study also identified some of the problems facing the full implementation of basic education in Nigeria. Such problems include: Poor education statistics inadequate publicity, inadequate funding of education, religion particularly in the Northern part of the country. inadequate infrastructure. Finally, the study made some recommendations which include: Proper and effective monitoring of the Basic Education Programme ,qualified teachers should be employed and the harmonization of teachers salaries be implemented immediately, more schools and classrooms should be built to accommodate pupils and students, there must be increased publicity, statistics must be properly kept and politics must be separated from education.
