ABSTRACT Information and Communication Technology is penetrating every facet of human life. The application of information and communication technology services for improving health care services is receiving attention in the research community. The application of electronic diary in the health sector will help health care providers to be effective and be able to satisfy their […]
ABSTRACT The Mfamosing Limestone is a shallow marine carbonate platform that was karstified as a result of subaerial exposure. Karstification of the limestone first occurred during late-Albian sealevel lowstand. During the deposition of the limestone, the porosity was originally dominated by primary pores (intergranular and intragranular). During early karstification, the original depositional fabric and related […]
ABSTRACT The distribution of porosity in the Albian Mfamosing Limestone was affected by, meteoric and burial diagenesis. During early subaerial exposure (meteoric diagenesis) primary pores were filled with calcite cement and internal sediments while fine secondary (matrix) pores and conduit pores (vugs, caverns, fractures) were formed. During burial, unlithified sediments (including grainstones) lost porosity by […]
ABSTRACT Partial or non-availability of water has been a consistent preoccupation of the inhabitants of Ikwuano local government area. The need to boost the water supply system here is becoming very necessary in recent times. Geophysical measurements were carried out in this vicinity between January and April 2010. Using Schlumberger configuration, vertical electrical sounding (VES) […]
ABSTRACT Some British coals from Northumberland and Scottish Fife were assessed based on petrographic, mineralogic and chemical evidence. This is consistent with the current emphasis on the use of both primary (prediagenetic) and secondary (epigenetic) mineralization episodes in the search for type differentiation of coals. The study presents ample evidence that the differences in the […]
ABSTRACT Erosion is a common problem in Calabar metropolis. This has resulted in the loss of a large volume of soil, lives and destruction of property worth billions of naira. This study was undertaken to identify the erosion sites, determine the causes of the erosion and suggest solutions. Structured questionnaires and field measurements were used […]
ABSTRACT Cloud computing has found its way into many fields of human endeavor, including education. In a normal face-to-face classroom environment, time and resource (classroom space) limitations often severely constrain the scope of experiences that students gain and the supervision they receive. To alleviate this difficulty, a blended approach for teaching, learning and assessment activities […]
ABSTRACT Water hyacinth (Eichhornia crassipes) samples were collected from twelve locations for the period of eight months (January – September,2011) in Oleri River. The samples were analytically prepared, treated and digested for trace metal analysis using atomic absorption spectrophotometry of Model Pye Unicam 2900. The trace element determined were iron, copper, zinc, manganese, lead, chromium, […]
ABSTRACT The concentrations of polycyclic aromatic hydrocarbons was determined in 9 popular smoked fish species Clarias gariepinus, Paranchana obscura, Heterotis niloticus, Sardinella aurita , Scomber scombrus, Pseudotholitus senegalensis, Ethmalosa fimbriata, Gymnarchus niloticus and Trachurus trachurus in the Nigerian market after hexane/dichloromethane extraction and clean up by gas chromatography with flame ionization detector (GC-FID). The 16 […]
ABSTRACT The levels of selected heavy metals in popular cigarette brands sold in Nigeria were determined using atomic absorption spectrophotometry. The levels of metals in these of cigarette ranged from 10.08-38.89 µg/g for Cu, 23.75-49.72 µg/g for Zn, 68.70-495 µg/g for Ba, 102-251 µg/g for Mn, <0.001-5.24 µg/g for Ni, ND-3.22 µg/g for Pb, ND-3.38 […]
