Environmental Assessment of Vehicular Emission in Port-Harcourt City, Nigeria

Port Harcourt is a coastal city located in the Niger Delta region of Nigeria, with very short dry season and long heavy rainy season periods. The objective of this study was to assess air pollution level from vehicular emission during the rainy season period. Three locations in the city noted for high traffic congestion were selected for the study. Air sampling in these locations were carried out for 11 days, covering peak and off peak periods. The following air pollutants were measured namely; nitrogen oxides (NOx), sulphur oxides (SOx), carbon monoxide (CO) and unburnt hydrocarbons (CxHy), as well as climatic elements – ambient temperature and relative humidity. The air pollutant levels obtained were compared with local and International standards. CO complied with International standard, but exceeded local standard. There is need for effective air pollution monitoring and control, this will go a long way to reduce the health risk associated with air pollution in the city

Predictive Analysis of Homosexualism as the Prime Cause of HIV/AIDS Outbreak

In this work, HIV/AIDS data from homosexuals, heterosexuals and lesbians were obtained from the internet. Computational tablenbsp ofnbsp ratiosnbsp ofnbsp homosexualsnbsp to heterosexuals,nbsp lesbiansnbsp tonbsp homosexualsnbsp fornbsp bothnbsp HIVnbsp andnbsp AIDSnbsp patientsnbsp asnbsp a functionnbsp ofnbsp timenbsp werenbsp madenbsp andnbsp plottednbsp usingnbsp shapenbsp preservingnbsp interpolantnbsp in MATLAB 7.9 toolbox. Observations were made of those ratios, as a function of time, that are above and below y-axis = 1. It was seen that homosexual to heterosexual HIV shoots off in 1998 and continues to rise. Homosexuals to heterosexual AIDS ratio are to cross y=1 line and continue to rise in the future (fig.2). Also in fig. 4, Hho/Nho rises geometrically, showing HIV as the cause of the rise. In fig 5, plots of HIV to normal people and AIDS to normal people show another geometric rise indicating that HIV and AIDS are responsible for the rise.nbsp From the foregoing observations, it is therefore imperative to assert that homosexualism has a big and major role to play in the advent of HIV/ AIDS. This result can be used by World Health Organisation (WHO), Centre for Disease Control (CDC) for the control of the spread of HIV/AIDS, and also by hospitals for those treating HIV/AIDS, especially those practicing homosexualism
