- "Feeding in poultry farming in most developing countries, like Nigeria, is still manually carried out as high level of human involvement is required. This places an exorbitant cost of production on the farmer and reduces the expected return from investment. Besides, human intervention to poultry feeding is limited to fatigue, negligence, unfavourable weather conditions, and improper administration of feeds. In this paper, we present a microcontroller based poultry feed dispensing system.The mobile intelligent system is capable of moving forward, turn left, right and has the ability to detect and avoid obstruction. The developed model shows how mechanical transmission systems in machine can imbibe human intelligence of poultry attendants with corresponding increases in cost-benefits and high profits yield from a reduced labour force in poultry farming.

- 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

- African migrant fiction, which recreates characters’ experiences at home and abroad, is increasingly preoccupied with the representation of dystopian realities. Critical appraisals of the fiction have largely focused on the representation of varied mobilities – migration, exile, transnationalism and afropolitanism – without adequate attention to the depiction of migrant characters’ experiences of traumatic stress, despite its ample representation in the fiction. This study was, therefore, designed to examine the recreation of trauma and characters’ responses to traumatic stress in selected African migrant fiction with a view to establishing that traumatic experiences are not limited to characters’ natal homes. Homi Bhabha’s model of the Postcolonial Theory and Cathy Caruth’s and Judith Herman’s models of Trauma Theory, served as the framework. The interpretative design was used. Ali Farah’s Little Mother (LM), Laila Lalami’s Hope and Other Dangerous Pursuits (HODP), Ben Jelloun’s Leaving Tangier (LT), Chika Unigwe’s On Black Sisters’ Street (OBSS), Alain Mabanckou’s Blue White Red (BWR), Brian Chikwava’s Harare North (HN), Fatou Diome’s The Belly of the Atlantic (TBA), and Noviolet Bulawayo’s We Need New Names (WNNN) were purposively selected for their depiction of loss, trauma and suffering. The novels were subjected to critical analysis. Trauma in the novels is doubled-edged, aligning with the dominant estimation of trauma as a double wound. Traumatogenic contexts and events in the postcolony as well as in the diaspora dominate the novels. Pre-migration stressors such as unemployment, poverty and sexual assault characterise the postcolony in LT, OBSS, HODP and TBA; while displacement, deprivation and violence abound in WNNN, HN, LM and BWR, all leading to characters’ experience of Continuous Traumatic Stress. Characters’ response to pre-migration stressors in all the novels is flight. Repetitively traumatised by oppressive poverty, displacement and the inconsistencies that define life in the postcolony, the characters fled their fatherland for the West through legitimate and illegitimate routes. In the diaspora, post-migration stressors are activated by characters’ experiences of disillusionment, racism, joblessness, physical and mental assaults, unhomeliness, the trauma of a paperless existence and the perpetual fear of police brutality. Characters’ responses to post-migration stressors range from developing Post-Traumatic Stress Disorder (PTSD) to committing suicide. Azel in LT and the nameless protagonist in HN experience dissolution of self and suffer from PTSD. In WNNN and LM, Tshaka Zulu, Uncle Kojo and Axad suffer from mental illnesses, while Moussa in TBA commits suicide. However, characters like Massala-Massala in BWR, Aunt Fostalina and Darling in WNNN, Faten in HODP and Efe, Ama and Joyce in OBSS largely display resilience in the face of trauma. There is recurring adoption of multiple narrative voices, symbolism and journey motif in OBSS, LM, HODP and HN, while irony and traumatic realism are employed in LT, WNNN, TBA and BWR. Migrant characters’ precarious, liminal and subaltern existence, both at home and abroad, bears witness to trauma’s mobility across space and time in African migrant fiction. This destabilises the hegemonic conception of the West as the Promised Land. 1 results 1
- Agbaja Ironstone Formation of the Lokoja district, Central Nigeria occurs within the Upper Cretaceous sedimentary sequences of the NW-SE trending Nupe Basin. Three lithostratigraphic units were delineated; Lokoja Sandstone (the oldest), Patti Formation and Agbaja Ironstone Formation. Lokoja Sandstone rests unconformably on the basement complex and grades from conglomerate to arkosic sandstone. Patti Formation consists of intercalations of sandstone, siltstone and carbonaceous mudstone units. Agbaja Ironstone Formation is made up of colites, pisolites and bog ore. Textural studies show a very finely to very coarsely skewed mesokurtic sands for Lokoja Sandstone and leptokurtic for Patti Formation. ZTR index value ranges from 61 to 81% for Lokoja Sandstone and 83 to 95% for the Patti Formation. Higher ZTR index value for Patti Formation indicates a relative higher mineralogical maturity over the Lokoja Sandstone. These sedimentological studies indicate a basement source for the sedimentary materials deposited under low energy short fluvial regime, that evolved into two facies; alluvial fans and flood basin. Four petrographic varieties of the Agbaja Ironstone Formation were identified; ooidal pack-ironstone, pisoidal packironstone, detrital mud-ironstone and breccia mud-ironstone Kaolinite ooids are spherical, oblong and fragmented, usually with pseudomorphs of goethite after pyrite at the core. Goethite pisoids cemented in kaolinitic to goethitic matrix are elliptical, oval, subspherical in shape and composite in nature. Constituent minerals of the mud-ironstone are kaolinite, quartz and heavy minerals. Paragenetic studies show that pyrite, siderite, kaolinite, quartz, mica and heavy minerals are the initial minerals of the ironstone while secondary enrichment minerals are goethite, hematite, goyazite-crandallite, bolivarite and boehmite. Chemistry of these minerals further classified them into ferritic kaolinite, kaolinitic ferrite and ferrite. Si02 ranges between 23.71 and 56.41 % and AI203 between 22.01 and 36.54% in all the unferruginized portions of the Agbaja ironstone. But both components can jbe as low as 0.22% in the ferruginized equivalent. Si02 and AI203 contents are highest in the mud-ironstone varieties and lowest in the pack-ironstone varieties. Fe203 content increases from about 1.59% in the unferruginized to about 97.54% in the ferruginized equivalents, for all the petrographic varieties. The highest concentration of Fe203 is in the pisoidal pack-ironstone. P20S values range between 0% in the unferruginized to 5.10% in the ferruginized portions, and often increase with increasing Fe203 contents. MgO, CaO, MnO, Na20 and K20 are generally less than 1.0% in all the petrographic varieties. Element mobility during ferruginization indicates that iron enrichment is accompanied by a parallel depletion in Si02 and AI203, moderate to extreme reduction in CaO, MgO, MnO, Na20 and K20 and a significant gain in P205. This relationship confirms the supergene nature of the replacement process (desilicification, removal of alumina and iron enrichment process (ferruginization). Sedimentological, mineralogical and geochemical studies provided evidences for a kaolinitic precursor for the ironstone deposit, contrary to the earlier proposed chamositic precursor. Also the presence of pseudomorphs of pyrite in nuclei and as incorporation into the concentric laminae of ooids are reliable indicators for a possible accretionary model for the formation of ooids and pisoids prior to ferruginization. Two ferruginization periods unrelated to lateritization were established; first won enrichment is supply due to oxidation of the initial pyrite/siderite and reconcentration of absorbed FeOOH in the lattice structure of kaolinite; second period is linked to the presence of bacteria (framboids) which is oxidised to form iron phosphate complex in the bog ore. The Fe and P were remobilised into the underlying pack-ironstone by descending meteoric water. 1 results 1
