- Understanding the basic mechanisms that govern flow of hydrocarbon in any given reservoir situation is necessary in developing reliable methods of predicting behaviour in that reservoir. Most reservoirs in Agbada Formation of the Niger Delta Basin are anisotropic and therefore heterogeneous, which is a vital parameter in the efficient production of hydrocarbons. This work looked at the effect of permeability anisotropy (Kv/Kh) or heterogeneous distribution and its effects on reservoir performance using windows based IPM-MBAL petroleum engineering software. Results analysis revealed that anisotropy makes reservoir production modelling more realistic than the isotropic scenarios, and degree of heterogeneity improves oil recovery from the reservoir (Kv/Kh = 1, R.F = 49.31%; Kv/Kh = 0.1, R.F = 49.95%; Kv/Kh = 0.001, R.F = 50.60%; Kv/Kh = 0.0001, R.F = 51.24%). Reservoir heterogeneity should be included in reservoir modelling practices because it has a significant effect on hydrocarbon production. 2 results 2
- A university’s objective is to educate its students using information and communication technologies (ICTs) and teaching techniques that would enable its graduates become flexible and life-long learners that can easily adapt to the changes eminent in the information society. Achieving this aim requires among other factors, the adoption of appropriate teaching model such as the project based learning (PBL) which supports the inculcation of collaborative and lifelong learning skills, technology use skills, knowledge sharing skills and social networking skills into students. Consequently, this study was carried out to evaluate the use of mobile phones by students involved in PBL in three randomly selected private universities in Nigeria. The questionnaire was used as the instrument for data collection from 750 undergraduates students distributed across the three selected private universities in southwestern Nigerian states. This is to say that 250 students were sampled from each of the participating private universities whose population was estimated to be about 2000 students each. Also, the use of stratified sampling technique ensured that only those students that were in their second, third, fourth and fifth year in the sampled universities, who were presumed to have acquired required learning experiences, participated in the study. The result showed that a significant percentage of the students studied had mobile phones and that they used their mobile phones for communication, interactions, getting information, browsing the Internet, and sharing knowledge anytime they were involved in PBL. It was also revealed that mobiles phones can be used to strengthen PBL in higher institutions and can be used to implement information services provided for students in their university. Although private universities in southwestern Nigeria amounts to about 43.9% of private universities in Nigeria, a percentage that makes them a sizable representation of private universities in Nigeria, the fact that the study sampled population was drawn from only three southwestern Nigerian based private universities made generalizing the results of this study as the situation in Nigeria in appropriate. The study however, provides first hand information on the prospects, gains and challenges mobile phones offer as appropriate education technology for implementing PBL in Nigerian universities 1 results 1

- Abstract: In statistical process control, detecting if the process is in control and the position of shift in an out-of-control process are critical research problems. If the normality assumption is satisfied, work has advanced in detecting shifts in mean and/or variance. However, the normality assumption is often not satisfied in many real life situations. We suggest a non-parametric Lepage-type change-point (LCP) control chart for jointly detecting process shifts in mean and variance, under non-normality. A comparison between our proposed method and a generalised likelihood ratio (GLR)-based method was made. Process data were simulated following normal and Laplace distributions. The performances of LCP and GLR were assessed and presented, using evaluated average run lengths, under the distributions considered. The LCP competed favourably with the GLR in a normal distribution. However, LCP outperformed GLR under the heavy-tailed distribution considered. We recommend the new approach for short-run situations where the underlying distributions are usually unknown. 1 results 1
- Academic libraries are facing challenges of competitive pressures, information availability, rising costs and a global digital environment. This situation calls for a better understanding of the specific needs of library users in order to provide the appropriate type and level of service that meets those needs. Assessment of service quality in libraries is one of the most reliable channels to know if clients are satisfied with services offered them. It is therefore imperative to investigate how library users perceive service quality. This paper examines the service quality and users’ satisfaction at Kenneth Dike Library, University of Ibadan and also examines how user surveys have been employed in a number of previously published literatures. A structured questionnaire was used to collect data for the study to evaluate the library’s performance by measuring the users’ satisfaction with (a) library services and resources (b) infrastructure/place/space and (c) suggestions for service improvement. The instrument was distributed randomly to a sample of 800 library users from the university. Suggestions are offered about ways library and information service providers could make more use of the information derived from their own and other organizations' user surveys to improve their services in order to survive. 1 results 1

- Background: COVID-19 is an emerging public health emergency of international concern. The trajectory of the global spread is worrisome, particularly in heavily populated countries such as Nigeria. The study objective was to assess and compare the pattern of COVID-19 spread in Nigeria and seven other countries during the first 120 days of the outbreak. Methods: Data was extracted from the World Bank’s website. A descriptive analysis was conducted as well as modelling of COVID-19 spread from day one through day 120 in Nigeria and seven other countries. Model fitting was conducted using linear, quadratic, cubic and exponential regression methods (α=0.05). Results: The COVID-19 spread pattern in Nigeria was similar to the patterns in Egypt, Ghana and Cameroun. The daily death distribution in Nigeria was similar to those of six out of the seven countries considered. There was an increasing trend in the daily COVID-19 confirmed cases in Nigeria. During the lockdown, the growth rate in Nigeria was 5.85 (R2 =0.728, p< 0.001); however, it was 8.42 (R2 =0.625, p< 0.001) after the lockdown was relaxed. The cubic polynomial model (CPM) provided the best fit for predicting COVID-19 cumulative cases across all the countries investigated and there was a clear deviation from the exponential growth model. Using the CPM, the predicted number of cases in Nigeria at 3-month (30 September 2020) was 155,467 (95% CI:151,111-159,824, p< 0.001), all things being equal. Conclusions: Improvement in COVID-19 control measures and strict compliance with the COVID-19 recommended protocols are essential. A contingency plan is needed to provide care for the active cases in case the predicted target is attained. 1 results 1
- Blogging, as a social medium, serves as a platform for individuals and organisations to produce rhetorical discourses that deserve scholarly attention. This rhetorical outlook of blogging features significantly in Middle East conflicts, as instanced in the Mideast blogs that cast their focus on the Israeli-Hezbollah war of 2006. Existing studies on blogging as a social practice seem to concentrate mainly on its social roles without paying much attention to its rhetorical outlook. This study explored the ideological nature of rhetoric in blog posts in order to establish how a comprehension of such rhetoric helps to create a better understanding of the role of blogging in the social process, especially in the context of conflict. A combination of socio-linguistic, semiotic and discourse analytic approaches, as expounded by M.A.K. Halliday’s Systemic Functional Linguistic theory, Teun van Dijk’s Triangulated Approach to discourse and Charles Sander Pierce’s semiotic theory, was adapted as the theoretical framework for the study. Ten Mideast weblogs, characterised by personal, collaborative and corporate blogs, which address the 2006 Israeli-Hezbollah conflict, and seven hundred and fifty posts, with two hundred and fifty readers’ comments, evenly distributed between the blog types, were purposively selected. The data, which are in three modes of signification -language, pictures and cartoons - were content-analysed. Bloggers employed three discourse structures - surface, schematic and dialogic – to pursue Zionist, anti-Semitic and Arab nationalistic ideologies in the posts. These three structures were arranged in a manner that got the blog readers into believing that they had made appropriate choices of response to the postings read, whereas their behaviours and opinions had been controlled through rhetorical strategies such as overstatement, understatement, metonymy, euphemism, mitigation and repetition, which all have a closer relation to underlying ideologies and belief systems of the bloggers. The surface structure contained nationalistic ideologies that were not overtly expressed but located in the linguistic and non-linguistic expressions that characterised the surface structure. The schematic structure defined the canonical order of the discourse through which topics were organised by conventional schemata such that subordinate topics were upgraded by assigning more prominence to them as headlines. The dialogic structure engaged the blog readers in imagined conversation, in which they were assigned passive role as mere commentators, whereas readers’ support was required for the credibility of the published news stories. The pattern of rhetoric in the posts was such that blog readers were made to tilt their views in support of the opinions expressed by the significations in the posts through the discourse strategies, a situation that made most comments in the posts align more with the viewpoints expressed by the bloggers. The nature of rhetoric in the Mideast posts indicates that bloggers conceal their opinions in various significations in an attempt to create strong persuasion for ideological support. The study has therefore provided the ground for establishing the Mideast blog posts as a site for readers’ manipulation in political communication, which is realised through rhetorical strategies embedded in the discourse. 1 results 1

- Charity Tithe (CT) in Deuteronomy was used to provide palliatives for the poor in Ancient Israel. Contrariwise, while groups likened to these are found in Nigerian churches, especially the Anglican Church, CT is not adopted, resulting largely in loss of members to other denominations practising a similar system. Existing studies on tithing and church poverty alleviation have addressed the obligatory nature of tithing, but little attention has been paid to the welfare values of CT as practised in Ancient Israel and as related to the Anglican Church. This study, therefore, examined the practice of CT and its effectiveness in Deuteronomy with a view to justifying the need for its existence in the Anglican Church and relevance in addressing poverty and membership situations in the Anglican Diocese of Ogbomoso (ADO). The study adopted the theoretic concept of “The Community of Goods in the Early Church”. The ADO was purposively selected because poverty alleviation is one of its main programmes. Four hundred copies of a questionnaire were administered to 40 clergymen, and 60 lay members each from the five archdeaconries and the Cathedral. In-depth interviews were conducted with 60 respondents involved in the Diocesan poverty alleviation programmes: 25 Clergymen and 35 lay members. Six focus-group discussions (FGDs) were held with ten members in each Archdeaconry and the Cathedral. Church membership/tithe records were consulted. Biblical texts (Deuteronomy 14:28-29; 26:12-15) were exegetically analysed, and quantitative data were subjected to percentages. Charity tithe in Deuteronomy, which was paid by every adult Israelite once in three years on agricultural products and stored in the clan gate, was used to tackle hunger (Deut. 14:28-29; 26:12-15). In the ADO where many of the population lived below poverty line, CT was non- existent, which caused a level of membership loss, but close to it was an offertory offering misconstrued by 72.4% interview respondents (clergymen: 37.0% and laity: 35.4%) as CT collected weekly for the poor. This generated ₦3.7m between 2005 and 2013 and catered only for 4.0% of the poor; 7.0% (27 people annually) of these left for other churches. A projective analysis from the questionnaire indicated that a faithful execution of CT would yield greater effects, generating ₦14.6m every three years from: farmers (1470:₦2.5m), civil-servants (315:₦6.5m), traders (525:₦2.8m), employees of private sectors/retirees/clergy (210:₦1.2m), artisans (385:₦1.5m), and students (595:₦120,000). These resources would have the following distribution: clergy (45:17%:₦2.4m), widows (113:18%:₦2.6m), orphans (121:20%:₦2.9m), strangers (322:23%:₦3.3m) and the unemployed (313:22%:₦3.2m). While 92.0% interview respondents supported the adoption of CT in empowering priests’ wives, orphans, youths and women, many of FGD participants opined that rural dwellers should be given priority in the distribution. Moreover, majority of the participants agreed that it would reduce the exodus of poor members to other churches. Charity tithe was non- existent in the Anglican Diocese of Ogbomoso, which, among other factors, led to loss of members. Given the success of the practice in Deuteronomy and its potential effectiveness in the Diocese, its adoption and faithful implementation by the Anglican Church would alleviate poverty and enhance evangelism 1 results 1

- Communal conflicts have arisen out of the context of mutual fear and suspicion over unequal distribution of socio-political and economic goods and lack of cordiality. Since most of the perpetrators and mercenaries who execute the conflicts are usually in possession of arms and ammunitions, it becomes very easy for them to perpetuate various criminal acts. This paper therefore examined the dynamics of communal conflicts and criminality in Nigeria. This paper demonstrated that communal conflicts engendered criminality in Nigeria,' however, little or nothing is known about the criminality angle/dimension of the incessant communal conflicts in Nigeria. The paper therefore recommended among others that, there is urgent needs for structural reforms to address the issues of poverty, social inequality, injustice and oppress ion so as to avoid situations that create communal conflicts. Governments should endeavour at all levels to work with the various communities to promote harmonious relationship among the various ethnic affiliations through the building of inter-ethnic civil networks at the community level which can be targeted for skills and capacity building/development programmes as a strategy for conflict management. 1 results 1
