Abstract: Porosity and permeability anisotropy distribution in parts of the Niger Delta was addressed in this study using core data. The core data was analyzed in laboratory to determine porosity, horizontal and vertical permeability from which permeability anisotropy was computed and cross plots were used to represent them graphically. Results from this study shows the porosity level of this formation and distribution along the well-column which suggests two stacked reservoirs at 3920 – 3930m and 3940 – 3970m. Horizontal permeability and Vertical permeability were observed to decrease with increase in depth. Permeability anisotropy decreases with depth, ranging between 5.33 and 5.8 x 10-4mD. The results of this work will reduce uncertainty in the exploration and evaluation of transmissivity of hydrocarbon from the reservoir

Abstract: Background: The United States Environmental Protection Agency (EPA) provided grant to the Centre for People and the Environment (CPE) to carry out a study titled "Landfill Recovery and Use in Nigeria". The closed dumpsite in Mpape was one of the landfills investigated. One of the recommendations in the report published by CPE in June, 2010 was the need to carry out detailed investigation to estimate the waste limits, depth, volume, and subsurface condition in order to fully determine the viability of the gas utilization system. To date, no study has been carried out on the closed dumpsite in Mpape in response to the recommendations. Therefore, we undertook this research to evaluate the extent of leachate contamination in Mpape, using integrated geophysical method.

Key Word: Dumpsite; Leachate; Electrical Resistivity; Contamination; Geophysical; Water; Contaminants.

Abstract: Background Static magnetic force is from the most important factors affecting all living creatures. This force investigated for its effect on human physiology, animal behavior and migration and plant germination and horticulture. Materials and Methods: Vicia faba seeds subjected to static magnetic forces arising from iron magnetic (4.0X2.5X1.0 cm, Y30H )in two regimes. The first one (A) post soaked seeds exposed to five magnetic cycles for 30 minutes and 30 minutes in between the two cycles. Then these seeds (A) soaked in tap water for six hours before starting the germination. The second portion (B), first soaked in tap water (Presoaked) for six hours, then exposed to the five cycles beside the Blank seeds.........

Key Word: Seed germination- Seedling anatomy- Seedling morphology- Static magnetic field- Vicia faba.

Abstract: A radiological assessment of groundwater in the Nile Valley aquifer has been carried out to detect the radiation risk and evaluate its suitability for human uses. Twenty three groundwater samples were collected from west Nag-Hammadi to Abu tesht area from the Quaternary aquifer which considered the only main source of fresh water in the area to investigate the radon gas concentration and its effective dose. The water samples were analyzed by Rad-7 Detector to determine the radon concentration. The obtained values of Rn222 concentrations range from 0.38 ± 13.0 to 5.44 ± 0.96 Bq l−1 with an average of 1.56 Bq l−1. The annual effective dose taken into the body were calculated for different age's groups such as adults, children and infants and ranged from 7.02 to 99.20 μSV Y−1 with average 28.54 μSV Y−1, from 5.62 to 79.36 μSV Y−1 with average 22.83 μSV Y−1 and from 4.04 to 57.07 μSV Y−1 with average 16.42 μSV Y−1 respectively. The activity of Rn222 and annual effective dose for the groundwater in the study area were lower than the MCL of the U S Environmental Protection Agency for public water supplies..

Abstract: Quantitative interpretations of aeromagnetic anomalies to estimate the thickness of sediments over parts of Bornu Basin of Nigeria have been carried out using spectral analysis so as to identify possible areas of hydrocarbon potential. The study area covers an area of approximately 12,100 located within latitude 12°0' to 13°0' North and longitude 12°30' to 13°30' East. Aeromagnetic data in grid format containing four sheets were analyzed and interpreted. First order polynomial fitting technique was used to separate the regional anomaly from the total magnetic intensity map to obtain the residual anomaly data that corresponds to the target source for further processing. The residual data was analyzed spectrally to obtain 12 spectral blocks for sedimentary depth estimates (deep and.....

Abstract: The study area is situated in Bauchi within the north-central Basement complex of Nigeria. It lies within latitudes N100 15' 00" to N100 18' 00" and longitudes E90 55' 00" to E90 59' 00'' and covers an area of about 38.52 km2part of quarter degrees sheet 149 Bauchi N.E. This work presents multidisciplinary data of migmatites in order to ascertain its different subdivisions. The field observations and petrology unravel 3 morphological units of migmatite: (1) Metatexite (2) Diatexite (Leuco-, Meso- and melanocratic) and (3) nebulite. This result favours a melting process; the presence of neosome suggests a high rheological contrast between the neosome and the surrounding rocks. The rocks consist of Biotite, Quartz, Plagioclase, Garnet, Orthopyroxene, Sillimanite......

Abstract: Legendary history ascribes its foundation to Raja Ben. (also spelt Bin or Bain) and described as Vena; minor hero king of Northern India, in the Mahabharat and the Puranas. Allegedly this Monarch new realized any tax from his subjects. He raised a part of the revenue by the sale of bijana (fans) manufactured by himself, because of which the place obtained its present name Bijnor (Bijnaur). Most probably the word is a corruption of Bijanagar (town of victory.
