Reduction of Cell Phone Electromagnetic Radiation Effect on Human Body

ABSTRACT Electromagnetic waves generated by different wireless systems like mobile systems, satellite systems, microwave links…etc. facilitates our communications throughout the world. These waves have many effects on the human body as well as our daily lives. The effects of electromagnetic waves cause many problems and diseases in the human body like cancer. Nowadays, types of the cancer caused by these waves has increased, because mobile users have increased. Because of the importance of ...

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...

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...

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...

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.

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 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.

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 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...

THE IMPACT OF ENVIRONMENT IN THE DISTRIBUTION OF PARASITIC INFECTIONS

ABSTRACT A human or animal with an infection has another organism inside them which gets its sustenance (nourishment) from that person, it colonizes that person and reproduces inside them. The human with that organism (germ) inside is called the host, while the germ or pathogen is referred to as a parasitic organism. Another name for an organism that causes infection is an infectious agent. It is only an infection if the colonization harms the host i.e parasitic relationship. It feeds and mu...

PRELIMINARY STUDY OF THE ANTIMICROBIAL EFFECT OF WATERMELON BARK (ENDOCARP OR RIND ON S. THPHI, E. COLI AND S. AUREUS

ABSTRACTIn a research conducted to ascertain the antimicrobial activity of watermelon (Citrullus lanatus) bark on organisms such as Escherichia coli, Slamonella typhi and Staphylococcus aureus using the ethanol and auqous extracts of the watermelon bark applying agar-well and pour-plate sensitivity technique.   It was observed that the ethanoic extract (dry) of watermelon bark on agar well showed a high inhibitory activity of Staphylococcus aureus and Escherichia coli and shows a moderate in...

Determining the incidence of Dengue in Ile-Ife

Pyrexia of unknown origin (PUO) is fever that occurs for no apparent reason with failure toestablish diagnosis within one week of investigation. The fever involves temperatures ofgreater than 38.3oC which occurs sporadically for more than three weeks. Fever resolvesusually after about 3 days but can take 2 weeks.Dengue is a tropical mosquito borne-viral disease and is marked by high fever and severe muscle and joint pains. It is caused by any of four antigenically and genetically distinct vir...

Influence of genetics and environment on grain quality.

AbstractWheat grain quality are strongly influenced by the effects of environment during grain fill. Environmental variables such as temperature, water and fertilizer influence the rate and duration of wheat grain development, protein accumulation and starch deposition in unique ways, and by different mechanisms. The effects of environment are superimposed on the intrinsic temporal patterns of gene expression during grain development. Integration of genomic and proteomic studies with developm...

Introduction to Computers

Introduction The computer as we know it is a group of pieces of hardware put together to get a job done faster. To accomplish its various tasks, the computer is made of different parts, each serving a particular purpose in conjunction with other parts. You don't necessarily need to know how these parts operate, at least not at this time, but you should be aware of their co-dependence to take advantage of their various characteristics.   The "computer" is an ensemble of different machines tha...

Quality Evaluation of Bread Made By Substitution of Bakery Fat with Bullet Pear (Canarium Schweinfurthii) Fruit Oil

Abstract Bullet pear (Canarium schweinfurthii) fruit oil was used as a replacement for bakery fat in bread production. Five loaves of bread samples were baked, the control sample was baked with 100% bakery fat and the other four loaves were baked with bullet pear fruit (BPF) oils as substitute for the bakery fat at 25, 50, 75 and 100% levels. The proximate, physical parameters and sensory quality analyses were carried on of these five loaves samples. The results showed some significant differ...
