The research work covered three distinct regions of fluid flow namely the laminar region the transition region and the turbulent region Appropriate flow charts and FORTRAN-90 source codes were developed to solve relevant fluid flow governing equations. Reynolds number was used as the control parameter to tune from laminar to turbulent flow while relevant solution was graphed using Microsoft Excel. The graph shows the distinct regions. The first region characterizes laminar region will) three straight-line segments. The second region is the transition region, which is in form of wavy line segments. The third region is the turbulent region in which higher wavy line segments are shown. The degree of waviness and number of wavy line segments increases from transition region to turbulent region. The result shows that fluid flow can be characterized through the use of random walk dynamics. " 1 results 1
- A pressure perturbation technique based on a simple adaptation of the Weirtheim's first order thermodynamic perturbation theory has been developed and used to formulate a generalized equation of state. The practical equation formulated was applied to pure fluids, binary systems and real samples of Niger Delta Petroleum fluids. Tuning of data is not required. The results show more accurate predictions than the commonly used SRK and PR equations. This work provides a theoretical framework for improving the accuracy of cubic equations of state. One major advantage of the generalized equation expressed in this work is the fact that it provides a theoretical framework for explaining the physical significance of the parameters in multi-parameter equations of state. Thus, in a three-parameter equation of state, while 'a' captures the attractive forces, 'b’ is the co-volume, 'c ' could represent non-physical forces. This is different from the concept of 'c' in such equations as Peng-Robinson EOS where 'c ' obviously represents an "after-the-fact" volume correction term. 1 results 1

- The study explores performance assessment models in academic libraries and show-cases the practical experiences at the Covenant University Library. The paper which is based on an observational study of the researchers’ daily work experiences and review of literature identified constraints to performance assessment in academic libraries and has attempted to give solutions. The paper concludes that academic libraries should overcome constraints and imbibe the culture of performance assessment that involves a continuous and periodic process of fine-tuning critical management and functional processes, either reactively or proactively through deliberately designed parameters (indicators). It extrapolated from the unique experiences of the Centre for Learning Resources, Covenant University to construct a model (Lib-PERFQUAL) for libraries around the world. This is a model that comprises all indicators necessary to maintain continuous relevance and achieve utmost efficiency. 1 results 1
- This article engages song melody and speech tone conflict in translated Yoruba Christian hymns between the late 19th and early 20th century. In their effort to make early Yoruba Christian converts sing Christian hymns in the church, European missionaries translated English hymns to Yoruba, and sang them to the original European hymn tunes. Yoruba being a tone language, requires a significant level of correlation between song melody and speech tone, for the words to retain their original meaning when sung. The tripartite constraint of aligning melody, meter, as well as meaning, posed a major problem to the hymn translators. Having given priority to melody and metre, the translators therefore, tend to compromise on meaning, thereby producing Yoruba hymns that will sound interesting melodically, and correlate metrically with the metre, but producing hardly meaningful words when sung. This study utilized samples from Iwe Orin Mimo, being the Yoruba translation of a range of hymns in Hymnal Companion, Hymns Ancient and Modern, and some other hymn books popularly used by the Church Missionary Society (CMS). The work presents a graphical illustration of the disparity between the hymn tunes and the speech tone of the Yoruba language. It also highlights the efforts of indigenous composers in correcting the perceived error through re-composition of the first stanza of selected hymns, to which they wrote more stanzas that align with the theme of the first stanza. The inappropriately translated Yoruba hymn books have remained strong institutions within the church and have therefore, continued to promote the use of the translated hymns in the Yoruba church. 1 results 1
