EXOSMOSIS AND ENDOSMOSIS VERIFIICATION USING WHITE RAW EGGS
ABSTRACT Exosmosis and endosmosis verification using white raw eggs have been carried out. Two beakers of dilute hydrochloric (HCl) acid solution were prepared. Two white eggs were placed differently into beakers labelled Beaker A and B respectively containing dilute hydrochloric (HCl) solution and left for five hours. Beaker A (containing Saltwater) was seen as more concentrated than the albumin in the egg. Water molecules moved from a low concentration point (albumin) to the high concentrat...
ASSESSMENT OF THE EFFECTS OF CARBONATED DRINKS ON THE ENAMEL OF THE TEETH
ABSTRACT Assessment of the effects of carbonated drinks on the teeth have been carried out. Five white shelled hard-boiled eggs were placed in clear cups and labelled (Soda Drink, Diet Coke, Coke, Tap Water and Vinegar), with the respective selected liquid poured into the cups and ensured the liquid covers the eggs placed in the cups. The eggs were allowed to sit for 72 hours. At 72 hours the eggs were removed from the cups for inspection. The egg in water showed no changes, this is because t...
DETERMINATION OF VISCOSITIES OF SOME SELECTED LIQUIDS USING STOKE’S METHOD
ABSTRACT Viscosity is a property of a liquid and is defined as the resistance of a liquid toflow. This research is to determine the viscosities of motor oils (10w – 40w, 20w –50w), vegetable oil and honey using the fall sphere method. The viscosity of honeywith 4.44Ns/m2was found to be the highest and that of vegetable oil having a valueof 0.002861Ns/m2 is termed the lowest. The viscosities of motor oils (20W-50W )and (10W-40W) were found to be 0.00468Ns/m2 and 0.00374Ns/m2 respecti...
CHARACTERISTICS OF POLLUTED SANDS A CASE STUDY IN NIGER DELTA (REVIEW)
ABSTRACT This study is aimed at using the characteristics of polluted soil to delineate different soil layers and deduce ways of providing remediation to the problems generated as a result of soil pollution using Electrical Resistivity Method. An inversion of the measured apparent resistivity values using a computer program was carried out to determine the true subsurface resistivity. This method was used to estimate the lateral and vertical extend to which a particular soil has been conta...
SEISMIC TIME-LAPSE RESERVOIR MONITORING
Time lapse seismic which geophysicists often abbreviate to four dimensional (4-D) seismic is a geophysical technique which involves simply repeating a series of 3-D seismic survey over time such that the fourth dimension is in “Calendar Time”. This gives it the ability to image fluid flow in a well volume.
FIBRE OPTIC IN RESERVOIR SENSING
Fibre optic technologies came out of military and space research and development programme. Until recently, glass chemistry and laser interrogation hardware have not been at a level of robust where systems could survive in down-hole environments for long periods. Because of the physical properties, glass can thrive as a sensor at extremely high temperatures and efficiently high temperatures and efficiently transmit large quantities of data where as in the past, one may have been limited to a ...
SEISMIC CHRONOSTRATIGRAPHY: PROSPECTS IN PETROLEUM EXPLORATION
Seismic survey has long become a trusted tool for hydrocarbon exploration. This is because of the outstanding ability of seismic reflections and their over lapping relationships to image deep and shallow subsurface structures and delineate promising structural and stratigraphic traps. These subsurface features become good prospecting targets, maybe because of their depositional history or post depositional events. With this in mind, it is necessary to draw out relationships between deposition...
Forensic Geophysics: Geophysical Techniques and Applications
Forensic geophysics can be seen as that involving the use of geophysical methods in the search, locating and mapping of hidden or buried features underground or underwater. Geophysical methods have the potential to aid the search and recovery of a target because they can nondestructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target or object is hidden in the subsurface.
REPORT ON GEOPHYSICAL SURVEYS AT IKOT NAKANDA, AKPABUYO LOCAL GOVERNMENT AREA OF CROSS RIVER STATE, NIGERIA
Geophysical field school is an annual academic camping exercise that is aimed at exposing students to the practical aspects of geophysics. It is a three (3) credit hour course for third year students of applied geophysics aimed at educating students on the handling of geophysical equipment and the rudiments of data acquisition, processing and interpretation. This year’s field school was held at Ikot Nakanda and its environs, in Akpabuyo locall government area of Cross River State. It w...
WASTES AND SEWAGE AS A SOURCE OF ELECTRICITY GENERATION
ABSTRACT Waste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to energy (electricity) using different technologies including collecting and converting current landfill gases, wet or dry anaerobic ...
EARTHQUAKE MONITORING AND SENSING IN NIGERIA
ABSTRACT This study reviews earthquake monitoring and sensing in Nigeria. The techniques used to monitor earthquakes include seismic, Global position system (GPS) and remote sensing methods. For now there is no scientific method of predicting earthquakes, but seismologists depend on the anomalous animal behaviour, radon emissions, trends, creep fault, drop/rise in the water level and anomalous plant behaviour for earthquake prediction. The study also revealed that Nigeria is not seismically f...
APPLICATION OF GIS AND REMOTE SENSING IN SPATIAL LOCATION OF OIL AND GAS PLATFORMS IN THE NIGER DELTA
ABSTRACT This study investigated the uses of GIS and Remote Sensing as a strategic tool for locating the positions of oil and gas fields. It has revealed the ability of GIS tool to develop database showing all the layers used for the study from logical to physical database design, bringing to the public domain, the applications of GIS and RS technologies using geospatial data in locating oil and gas platforms in the Niger Delta and in Akwa Ibom State. This work has exposed the vast applic...
Analysis of the Causes of Road Failure in some parts of Nigeria (A Review)
ABSTRACT This research assesses the various factors responsible for road failures in the southwestern and south-southern parts of Nigeria with the aim of reporting findings to the public domain. The research further stressed the importance and relevance of geophysics in evaluating civil engineering structures such as roads. The above goals were met by studying the results of surveys carried out by researchers in southern Nigeria. Electrical Resistivity and Electromagnetic methods have been us...
