One-Stage Implicit Rational Runge-Kutta Schemes for Treatment of Discontinous Initial Value Problems
P.O. Babatola,R.A. Ademiluyi,E.A. Areo
Journal of Engineering and Applied Sciences , 2012,
Abstract: This study describes one-stage Implicit Rational Runge-Kutta scheme for treatment of discontinuous ordinary differential equations. Its development adopts power series expansion method (Taylor and Binomial). The analysis of its basic properties uses Dalhquist model test equation. The results show that the schemes are consistent, convergent and A-stable. Numerical computations and comparative analysis with some standard methods show that the new schemes are efficient and accurate.

A new paradigm for implementing ecologically - based participatory IPM in a global context: the IPM CRSP model
Heinrichs, E.A.;
Neotropical Entomology , 2005, DOI: 10.1590/S1519-566X2005000200001
Abstract: integrated pest management (ipm) is a key component in the development of sustainable agro ecosystems. the integrated pest management collaborative research support program (ipm crsp) is a usaid funded project that is a consortium of u.s. universities working with host country national programs and other stakeholders to promote ipm globally. the ipm crsp model is based on a participatory integrated pest management (pipm) process that has as its goals to help reduce: agricultural losses due to pests, damage to natural eco-systems including loss of biodiversity, and pollution and contamination of food and water supplies. the ipm crsp participatory model is based on networking, institution building, private sector interaction, research-technology development and technology transfer. the new ipm crsp beginning in 2005 will build on the experience of the previous ipm crsp (1992-2004). the technical approach of the new ipm crsp is to implement an ecologically-based, participatory ipm (ep-ipm) program with a carefully-conceived strategy for local, national, regional, and global diffusion of ipm capacity and knowledge. broad participation and communication are critical components of the strategy, along with a competitive process and a management plan designed to ensure high quality research and accountability. the approach is based on a competitive process open to u.s. universities who are expected to partner with host country national programs and other stakeholders in the development of regional ipm centers and on five global ipm themes including invasive species, insect transmitted viruses, regional diagnostic laboratories, information technologies and databases, and impact assessment.
Programa Emprendedor Obligatorio: Alternativa de Educación Integral
Formación universitaria , 2008, DOI: 10.4067/S0718-50062008000600006
Abstract: this article discusses the application of an enterprising program for engineering careers in higher education schools. the accreditation system in mexico, which applies to these schools, considers the inclusion of some courses in social sciences, but the number of courses needed for the integral formation of the future engineers is limited. therefore, an enterprising program which includes courses such as finances, marketing, human relations and social psychology is proposed and analyzed. the program has shown to be effective since it exposes students to practical cases that they will find during their professional life.
An old approach for new investigations in the IBA symmetry triangle
McCutchan, E.A.;
Revista mexicana de física , 2006,
Abstract: motivated by the success of the x(5) critical point model in describing the properties of certain rare-earth nuclei, iba-1 calculations are performed for rare-earth isotopic chains. contours of basic observables are discussed and used to extract parameter values. the properties of all low-lying positive parity excitations are well described for a wide range of nuclei and the resulting parameters are mapped into the iba symmetry triangle. the simple, two parameter iba-1 calculations are also extended to the pt isotopic chain. both energies and electromagnetic transition strengths are are found to be well described over the entire isotopic chain suggesting these nuclei can be described more simply without the need for introducing an intruder configuration.
The ‘consensus genevensis’ revisited
E.A Boer
Acta Theologica , 2004,
Abstract: In the weekly Bible study meetings on Fridays in Geneva, called les congrégations, biblical books were expounded in lectio continua. On one occasion the doctrine of divine election was presented over against the intervention of Jerome Bolsec. The ministers of Geneva presented their internal consensus on predestination and sought the approval of the Swiss churches. This paper argues on historical, literary and material grounds that not Calvin’s book De aeterna praedestinatione Dei of early 1552, but the Congrégation sur l’élection éternelle de Dieu of 18 December 1551, should be identified as the ‘Consensus Genevensis’. The doctrine of predestination was not a particularity of John Calvin’s, but a point of teaching the Scriptures, shared by the Genevan ministers.
A brief overview of Bible translation in South Africa
E.A. Hermanson
Acta Theologica , 2002,
Abstract: Christianity came to South Africa in 1652, but missionary outreach to the indigenous population only began in earnest in the 19th century. The first formal-equivalent Bible translations were done by missionaries in the latter part of the 19th and early 20th century. Since the mid-1960s the Bible Society has facilitated functional-equivalent translations by teams of mother-tongue translators, and is currently completing the Old Testament in Southern Ndebele, the only South African official language without a complete Bible. Advances in translation theory present new challenges in translating the Bible to communicate in the contemporary linguistic situation. (Acta Theologica, Supplementum 2, 2002: 6-18)
Interface Properties Between Lateritic Soils from Ife Region of Southwestern Nigeria and Some Foundation Materials
E.A. Okunade
Journal of Engineering and Applied Sciences , 2012,
Abstract: The interface properties between some lateritic soils within the Ife region in southwestern Nigeria and some common foundation materials (namely concrete, steel and wood) were investigated by the direct shear test method employing the shear box apparatus adapted specifically for that purpose. The values obtained were compared with the shear strength characteristics (cohesion and angle of internal friction) of the soils. The angles of interface frictions between the lateritic soils and concrete, steel and wood ranged from 24.6 and 41.2 , 17.5 and 34.0 and 12.0 and 16.0 , respectively, while the adhesion between the lateritic soils and concrete, steel and wood ranged from 15.8 and 30.2 kPa, 11.2 and 18.5 kPa and 7.5 and 10.8 kPa, respectively. The angles of internal friction and cohesion of the soils ranged between 29.1 and 40.7 and 23.7 and 32.3 kPa, respectively.
Engineering Properties of Lateritic Adobe Bricks for Local Building Construction and Recommendations for Practice
E.A. Okunade
Journal of Engineering and Applied Sciences , 2012,
Abstract: The engineering properties of adobe bricks produced from lateritic soils taken from three different locations in the Ado region in Southwestern Nigeria were investigated. An analysis of the index properties of these soils revealed that they are suitable for the production of adobe bricks. Relatively high values of the compressive strengths of the bricks (between 1.94 and 2.18 MN m 2) were attained due to controlled compaction during moulding and adequate monitoring during the curing process. It was observed that the water absorption capacities were very low and that in fact the compressive strengths gained during drying were completely reversible upon rewetting. Consequently, clear-cut recommendations for practice on construction with adobe bricks were provided to ensure the safety and durability of the structures.
Design and Implementation of a Web-Based Geotechnical Database Management System for Nigerian Soils
E.A. Okunade
Journal of Engineering and Applied Sciences , 2012, DOI: 10.3923/jeasci.2010.320.326
Abstract: A Web-Based Geotechnical Database Management System (GDBMS) is developed for Nigerian soils. The point database (Geo Data Nigeria) comprises the results of soil tests and observations from past soil investigations by different researchers and from diverse sources with a view to maximizing the economic and scientific benefits of such test results by ensuring their unlimited accessibility. Adequate web interface is provided without limitations to all members of the public to query, report and visualize the data contained within the database. The system is designed to be infinitely extensible as managed by authorized administrators. Appropriate data templates are therefore provided for data submission while ensuring data integrity and accuracy before inclusion in the database. The data are stored raw without any pre-analysis, giving the potential users the freedom to make their own independent deductions from them. Recommendations are made to enhance the management and continual expansion of the database.
