Semiannual Variation of Dst-Related Disturbance and Association with Solar and Geomagnetic Activity

ABSTRACT A study of the semiannual variation of the Monthly mean Dst-related disturbance in H and Z components of the geomagnetic field has been carried out. Magnetograms from fifteen (15) geomagnetic stations in the high- mid- and low latitudes, and which includes three of the stations used in computing the Dst index have been analyzed. Sixty-one years data (1950-2010) was utilized. The H-component (Hdiff) and Z-component (Zdiff) of the Dst-related disturbance were computed by removing the s...

Effect of Solar Radiation on Human Response during Block Laying in Ogun State, Nigeria

Considerable numbers of outdoor workers worldwide are exposed to solar radiation and this exposure induces various adverse health effects on the workers. This study was conducted to determine the effect of solar radiation on human response during block laying in Ogun State, Nigeria. Two hundred and four masons performing block laying in outdoor environment were investigated between January and December. The meteorological parameters were measured and recorded around the mason which in...

A Critical Evaluation of the Environmental Impact of Gas Flaring by Oil Companies Operating in the Niger Delta Region of Nigeria

ABSTRACT Gas flaring is one of the associated activities of the oils and gas industry, which poses negative impacts on the environment such as climate change, impact on health and economic loss. The Nigerian government has tried putting a stop to gas flaring but to no avail, there is a continuous flaring of gas by oil companies operating in the Niger delta.  This research answers the question of the volume gas flared by Oil Company and also the increased or decreased volume flared.
