    A model is developed that will allow the fireman to stand as far back as possible from a collapsing wall of a storey building while directing a water jet into a window of the burning building. The variables in the model are therefore, the initial angle (α) and the distance of the fireman from the wall (x). Data collected from Imo State Fire Service, Nigeria, were used in validating the model. The model gives 60o as an optimum initial water jet angle to the horizontal. With 60o as the initial angle, the optimum distance is dependent on the initial velocity of the gun. This can be applied in a burning storey building that is in the risk of collapsing anywhere in the world. The optimum distance from the wall must satisfy equation (10). The work enables the fireman to know a particular point to stand near the building with respect to initial velocity of water fountain and its initial tilt to the horizontal

    Abstract: The reincarnation myth is a global concept, founded basically in religion and tradition. It was especially vibrant in the ancient times in places like Egypt, Greece, and in continents like Asia and Africa, which possess varying understandings of the myth. In Igbo tradition, for example, it is believed that reincarnation occurs within a family. And that some of the marks of reincarnation are usually the possession of the birthmark or certain other physical features and the exhibition of character and behavioral traits of a deceased person by a living member of his/her immediate or extended family. Thus, reincarnation entails the return to life of a deceased person in a new body. Sometimes, revenge is the mission of a reincarnated body. Bearing other reincarnation intentions in view, we study Achebe’s Okonkwo as one who falls within this category of reincarnation for revenge, having reincarnated through the body of his grandson Obi in No Longer at Ease to avenge himself against Umuofia and to suffer his son Nwoye, who now fathers him as Obi, for perhaps having had the effrontery to have left him and his ancestral tradition for the religion of the white man

    The work was carried out in Fugro Consultants Nigeria Limited, Port Harcourt. It was the identification, extraction and characterization of chemical compounds responsible for making termination. The results showed that termitarium contains 11.6 (g/kg) of TOM; 15.9 (mg/kg) of Magnesium, 11690 (mg/kg) of iron and 23.3 (mg/kg) of extractable chloride which are responsible for structural stability of termitarium. The result also revealed that increase of clay content enhances the structural stability of termitarium. % water absorbed Vs time(s) for control and termitarium, mean number of seedings Vs time (days) for control and termitarium, gave their R-square (correlation coefficient) as 0.9975, 0.9951, 0.9959, 09807 and 0.09995 respectivel

    Malondialdehyde levels of frozen fish, chicken and turkey on sale in Benin City markets

    75 samples of frozen turkey, chicken and fish sold in Benin City markets, Nigeria were screened for lipid peroxidation by colorimetric estimation of their malondialdehyde (MDA) contents. All samples contained extremely high levels of MDA. The order of MDA profiles was fish > turkey > chicken. MDAlevels within chicken and turkey samples varied from market to market, while values for each of the 5 fish species studied were fairly comparable. Highest levels of MDA were obtained in oily fishes, Trachurus trecae and Scomber scombrus. These results and their likely implication for consumerhealth are discussed in relation to the well-known mutagenic and cytotoxic effects of MDA
