Abstract: Geophysical survey involving electrical resistivity methods has been carried out at Annunciation grammar school, Ikere- Ekiti, southwestern Nigeria with the view to delineate the geo-electric characteristics of the basement complex and evaluate its groundwater potential in the area. A total of 5 vertical electrical sounding stations were established within the site along 5 traverses.
The schlumberger configuration was used for the data acquisition. The half –currents electrode (𝐴𝐵2 ) used range from 1 to 100m. The quantitative interpretation of the VES curves involved the use of partial curve matching and the 1-D computer iteration technique. The depth sounding interpretation results were used to generate geo-electric sections from which the aquifer was delineated. The geo-electric section drawn from the results of the interpretation reveal five subsurface layer which comprises of the topsoil, lateritic sand, partially weathered, weathered and fractured basement. The weathered and fractured layers constituted the aquiferous zone in all the stations. Hence, from this project work it is recommended that boreholes can be sited in high conductivity zones in VES 1,2,3 and 4 as they contain probable aquifers. The depth of any borehole should be located between 15m and 30m to take advantage of the basement fractures
Keywords: Geo-electric, overburden, lateritic, resistivity, foundation

Abstract: In this study a new model for quantifying the effect of evaporative cooling produced by the evapotranspiration from trees on the air temperature of Ali- Al Sharqi town, south of Iraq, (lat. 32.1ºN, long 46.85ºE) was suggested. The ASCE and FAO Penman Monteith model was used to calculate the actual evapotranspiration from a tree in the selected town. The dispersion of moisture from trees in the neighborhood in the three dimensions by using the Gaussian dispersion model was estimated. The decreasing of air temperature due to the moisture added by trees on a specific control volume was calculated by using the psychometric chart. The maximum cooling degree achieved by the suggested model reached to 2.6 ºC in July while minimum value was (1.8 ºC) and appeared in April. The results of applying the model on a hot and dry day indicated that the higher cooling degree can be obtained reach to 3.6 ºC at the noon time.

Abstract: Over thirty Vertical Electrical Sounding survey were carried out in Tofa and Rimin Gado local<
government areas of Kano state. Dynamic water level from open wells was also collected and was used as a<
guide for the selection of the electrode spread. The schlumberger array with a maximum electrode spread of
100 m was employed in all the points. Results from the sounding data indicates that the area is generally
underlain by five geoelectric or geologic section which include Lateritic top soil or Lateritic sand, Silty sand or
Sandy clay, Weathered basement or Clayey sand, Fractured basement and Fresh basement. Based on the result
obtained the weathered as well as the fractured basements forms the aquiferous zone within the study area, with
the weathered being more promising. The resistivity of these zones varies from 9 to 1640 Ωm with an average
value 255 Ωm, while the thickness varies from a value of 1.66 to 28 m with an average value of 10.67 m. Depth
to this zone varies from 5 to 31 m with an average value of 8.1 m. The study also shows that the Rimin Gado<
area appears to have more potential for groundwater development as compared with the Tofa area.

Abstract:A computer aided simulation study of electron and hole ionization rates in GaAs with reference to
the Terahertz source of power called IMPATT diode is presented in this paper. It is based on the breakdown
voltage calculation using the computer simulation method developed for the DC analysis of an IMPATT diode.
The comparison of simulation results reveals that the break down voltage calculated using carrier ionization
rates data reported by Pearsall et al is in good agreement with the experimental reports.

Abstract: This paper considers the possibility of making a qualitative test on Tamil Nadu rainfall data for
chaos from a simple nonlinearity test . we have employed the surrogate data method which gives information on
the significance of amount of non linearity involved in a time series data. We have calculated the Lyapunov
exponent for the surrogate data and the original data . The distinct results obtained from both the surrogate
data and the original data implies that the time series under consideration is chaotic

| Title | : | Apparent Jet Speed versus Optical Classification: An Effective Test of Unified Model in Powerful Radio Sources |

Abstract: We have carried out some statistical tests of relativistic beaming and radio source orientation
scenarios using optical class, apparent jet speed (βapp) and redshift (1+z) of a sample from Kellermann et al
(2004) as orientation indicators. The final compilation consists of 96 sources. 11 FRII radio galaxies and 85
radio-loud quasars were used for the analyses. Our results show that quasars have higher apparent jet speed
than galaxies with the respective mean values as 6.833 and 1.209. This result is consistent with the simple
relativistic beaming and orientation-based unification hypotheses in which quasars are the beamed
counterparts of powerful radio galaxies which form the isotropic parent population. In order to further test the
unification scheme for these objects, correlation analysis of the observed parameters for the two optical classes
was performed. The result shows strong evidence that FRII radio galaxies and quasars are intrinsically the
same but appear different due to relativistic beaming and orientation effects.

| Title | : | Dark-Bright Solitons Conversion System for Secured and Long Distance Optical Communication |

Abstract: We suggest a new purpose of a security scheme by employing the nonlinear behaviors of temporal
dark and bright solitons amongst a micro-ring resonator system for signal security application. The chaotic
signal is generated, where the required bright soliton pulse can be recovered and discovered by an add/drop
filtering device. By using the reserve ring parameters, simulation results obtained have demonstrated that the
soliton conversion can be performed. In application, the chaotic signal is generated and formed by the dark
soliton inside a nonlinear micro-ring device. The different temporal soliton response time can be seen, the
response times of 169 and 84 ns are mentioned for temporal dark and bright solitons, respectively, which can
also be used to figure the security key. The technique of optical conversion can be use to improve the optical
communication network systems.
