Detection of Caprine Arthritis Encephalitis Virus Gag-Gene by RT-PCR from Experimentally Infected Goat Brain Cells
I.A. Adebayo
Research Journal of Biological Sciences , 2012,
Abstract: Different brain cell types obtained from goat cerebrum explant cultures were prepared from newborn goat kids and infected by direct Caprine Arthritis Encephalitis (CAE) virus application. Predominantly, cells of the monocyte-macrophage lineage were specifically infected by the virus as proviral DNA was detected in infected cultures by amplification of a 414 base-pair (bp) fragment of the viral gag-gene by Reverse Transcription-Polymerase Chain Reaction (RT-PCR) technique. The present study revealed that microglia are the target brain cells infected by the CAE virus. This finding will undoubtedly help in devising some immuno-prophylactic measures to be adopted in the management of neurological dysfunctions resulting from retroviral infections of man (HIV) and animals.

L.C Nwanna, I.A Adebayo, B Omitoyin
African Journal of Biotechnology , 2009,
Abstract: Eleven diets (D1 - D11), designated as treatments (T1 - T11), supplemented with different levels of inorganic phosphorus (P) (CaHPO4) were fed to Heterobranchus bidorsalis (10.8 4) were fed to Heterobranchus bidorsalis (10.8 4) were fed to Heterobranchus bidorsalis (10.8 ± 0.02 g) to determine the optimum P requirement. D1 - D11 contained total P of 10.2, 10.4, 11.0, 11.9, 12.3, 12.6, 13.4, 13.9, 14.2 14.7 and 15.4 g kg-1 respectively. After 84 days of feeding trial, there was increase in fish growth up to T5 with 12.3 g P kg-1 diet, followed by consistent decline in growth towards T11 with the highest P content. However, fish in T5 had the best (P < 0.05) growth performance and feed conversion ratio (FCR). Fish in T1 and T2 had the highest (P < 0.05) FCR. Carcass protein was the same in T5, T6, T7, T8, T9 and T10, which was higher (P < 0.05) than in T1, T2, T3 and T4. Carcass fat content was highest in fish in T1 which also had the lowest water content. P and Ca concentration in fish carcass increased linearly and was highest (P < 0.05) in fish in T11, while Mg and Zn were highest (P < 0.05) in fish in T5. Data from the study suggest 12.3 g P kg-1 diet as optimum requirement for the growth of Heterobranchus bidorsalis.

T.A.M. Awoniyi,I.A. Adebayo,I.B. Osho
International Journal of Tropical Medicine , 2012,
Abstract: Infection by Cordylobia anthropophaga was observed in an 8-year old boy in a family of six living in a farm house located on a plot of land, 50x40 m in the South West of Nigeria. The farm has a 500 caged layer-unit, 6 goats and 3-sow units both on semi-intensive system and three watch dogs. This infestation (Cordylobia) was also observed to be very massive on two of their dogs and on the perineum of a pregnant sow from where the larva borrowed through the vaginal wall and reaching the uterus, causing straining and prolapse. An inspection round the farm premises revealed improper disposal of the domestic and livestock manure which attract intensive fly breeding. This observation stresses the importance of farm hygiene, good management and thoughtful planning that would enable correct location of a farm house within the farm premise for effective control of zoonoses.

International Journal of Engineering and Advanced Technology , 2013,
Abstract: In order to ensure that electrical power transfer fromgenerator to consumers through the grid system is stable, reliableand economical , it becomes imperative to carry out power flowstudies. This paper presents power flow solution incorporatingload tap changing transformer (LTCT) for solving the steadystateproblems of longitudinal power system using Nigerian330kV transmission system as a case study . In this work, theadopted numerical technique for solving the power flowproblems was the Newton Raphson iterative algorithm. Modifiedpower flow algorithm was implemented by the application ofvoltage control method using a load tap changing transformer(LTCT). Simulations were done using MATLAB softwarepackage .The results obtained from the existing condition of theNigerian 330 kV transmission Network indicate that the busvoltages at New Heaven (0.929p.u), Gombe (0.886p.u), andKano(0.880p.u) were below the set of binding limits that is,10% tolerance. With the incorporation of LTCT, voltagemagnitudes of 0.995p.u, 0.950p.u and 0.996p.u were obtained atNew Heaven, Gombe and Kano respectively, while the totalsystem active power loss on the transmission line also reduced byabout 5.1%.

I.A. Adejumobi,I.G. Adebayo,A.J. Olanipekun
Journal of Innovative Research in Engineering and Sciences , 2011,
Abstract: The demand on the electric power for the household, commercial and industrial loads is on the increase. Also, the management of electric distribution system is becoming more complex. Lack of information at the base station on the status of the distribution network has been identified as the major bottleneck to its effective monitoring and control. This work is a development of Microcontroller-based Electric Distribution Automation system for the purpose of effective monitoring and control of distribution system. Designed components include Remote Terminal Unit (RTU) with Microcontroller(ATmega8A) as the major component for acquisition, monitoring, transmission and processing of data; Modulation and Demodulation (MODEM) module for serial data communication; Man–Machine interface(MMI) which is the Distribution Automation Software designed with Visual C-Sharp,2008 and it is residents on Personal Computer(PC). The modules circuits were built on the Printed Circuit Board (PCB) whose design was custom-made using PCB Editor Software. To authenticate the functionality of the developed MODEM, high frequency signals at the extremes 50 kHz, 100 kHz, 200 kHz and 500 kHz, using 12volts signal source was impressed on MODEM. The responses shown on the Oscilloscope indicated that it is possible, using the developed system, to generate the high frequency signals necessary to establish communication between the distribution substation (DSS) modules. The next stage of this work is the implementation.
Geochemical Exploration for Gold and the Association of As-Cu-Pb-Sn-Zn-Li in the Upper Proterozoic Granitoids of the Wadi Rumman Area, Southwest Jordan  [PDF]
I.A.A. Bany Yaseen
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.610089
Abstract: The geochemical studies were conducted in an area covering about 15 km2of the south side of the Wadi Rumman area, SW Jordan. The study area included a part of a basement of complex exposed rocks in southwestern Jordan. The complexes comprised igneous and metamorphic suites, mostly from the late Proterozoic age. A systematic geochemical sampling was conducted using rock and heavy mineral-panned concentrate of geochemical samples. Fifty rock samples were collected from the granitic rocks, simple pegmatite dyke, quartz veins and alteration zone, which covered the area. Next, 45 heavy mineral-panned concentrate samples were collected from the alluvium in the stream sediment within the catchment area, and the dray was sieved to less than 1 mm grain size. The geochemical samples were analyzed for their trace elements and gold by using Ione Conductive Coupled Plasma Emission Spectroscopy (ICP-AES) and the Atomic Absorption Spectrometer (AAS) at Natural Resources Authority (NRA) Labs. The results of the geochemical analysis indicated the presence of gold and heavy minerals in the study area, a result considered abnormal in the rock samples. A strong positive correlation was recorded of Au with As, Cu and W (r =0.82, 0.7 and 1.0), as with Mo (r = 0.83), Cu with Pb (r = 0.83), Sn with Mo (r = 0.73), Mo with W (r = 0.97), Zn with W (r = 0.71), and Li with Bi (r = 0.7). These correlations revealed gold associated within the hydrothermal alteration, quartz veins and pegmatite dyke. Abnormal metals such as As and Bi were good path-finders to find Au. The HM samples showed low positive linear correlations among the concentrations of Au with As, Zn and Li, and negative linear correlations of Au with Pb, Sn, Bi and W. The combination of both rock and heavy mineral concentrate samples shows four geochemical anomalous areas of gold and heavy minerals. The geochemical signatures of Au and As in the Wadi Rumman appear to be in the hydrothermal alteration, quartz veins and pegmatite dyke, respectively. Heavy mineral concentration sampling delineated the Au geochemical anomaly in area 1 specificities with the rock geochemical anomaly of area 1.

Cytokines in innate and acquired immunity to Trypanosoma cruzi infection
Abrahamsohn, I.A.;
Brazilian Journal of Medical and Biological Research , 1998, DOI: 10.1590/S0100-879X1998000100015
Abstract: resistance to trypanosoma cruzi infections is critically dependent on cytokine-mediated activation of cell-mediated immune effector mechanisms. this review focuses on the role of il-10, tnf-a, ifn-g and il-12 in controlling t. cruzi replication by the innate and specific immune systems of the vertebrate host. a study performed on mice with disrupted recombinase-activating genes (rag/ko), which lack t and b lymphocytes, revealed the importance of il-12, ifn-g and tnf-a in the resistance against t. cruzi mediated by the innate immune system. in addition, data from experiments using il-10 ko, rag/ko and double rag/il-10 ko mice indicating an in vivo regulatory role of il-10 in innate and t. cruzi-specific immunity are discussed

I.A. Adetunde
Research Journal of Applied Sciences , 2012,
Abstract: This study is concerned with dynamical behavior of Euler Bernoulli beam traversed by uniform partially distributed moving masses. The governing partial differential equation was systematically analyzed and the analytical numerical solution for classical boundary condition obtained. The deflection of the Euler- Bernoulli beam is calculated under various specified conditions and the results displayed graphically. It is found that moving force solution is not an upper bound for an accurate solution of the moving mass problem.
