Abstract: This study was carried out to determine the prevalence of intestinal parasites from abattoir effluents. A total of 200 samples were examined out of which 50 samples each from Goat, Sheep, Pig and Cow respectively. These samples were processed using standard parasitological techniques including macroscopy, microscopy; formol ether concentration and modified Ziehl Neelsen method. Out of the 200 samples examined 109 where positive for intestinal parasites. This result revealed an overall prevalence of 54.5% in all. A total of 30 (60%) was recorded for goat, 23 (46.0%) cow, 29 (58.0%) sheep and 27 (54.0%) pigs. The prevalence of different parasites encountered included Ascaris suum (5.6%), Trichuris trichiura (3.2%), Hookworm (24.2%), Strongyloides stercolaris (0.8%), Teania spp. (2.8%), Enterobius vermicularis (7.1%) Trichostrongylus (8.3%), Diphyllobothrium latum (0.4%), Schistosoma intercalatum (0.1%), Fasciolopsis buski (8.3%), Fasciola hepatica (3.2%) and Metagonimus yokogawai (0.4%). Others were Paragonimus westermani (0.4%), Entamoeba coli (9.9%), Entamoeba histolytica (6.7%), Giardia lamblia (4.4%), Trichomonas hartmani (0.8%), Balantidium coli (11.1%) and Oocyst of Crypstoporidium (2.0%). The highest prevalence was hookworm (42.6%) in goat and Balantidium coli (60.7%) in pigs. Fasciolopsis buski and Metagonimus yokogawai had the lowest prevalence (0.4%). There was a significant prevalence of intestinal parasites in effluents of Jos Abbatoir.

Abstract: Hybrid composites have developed and demanding industrial application and replaced metals and non-metal by specific characteristics. The research work concerned with E- glass epoxy and E-glass / Kevlar 49 reinforcement epoxy. The reinforcing materials oriented at 0°/90°, 45°/45° and 30°/60° lay-up placement. The laminate was produced by hand lay-up method Vacuum Bagging Resin Transfer Molding Technique is used for air escape from the mold cavity for effective adhesion between layers of structural composites. The experimental results achieved by conducting hardness of the samples by following the ASTM standard. The ASTM D-2240 durometer was made to perform hardness over the standard samples. The water absorption characteristics of each specimen of different orientation were observed at different humidity level. Electronic weighing balance ASTM D-570 and Electronic densimeter ASTM D-792 was used for water absorption and density respectively. GFK-0°/90° (Glass fiber and Kevlar 0°/90°) has good hardness result and low density, GF 0°/90° has higher density and low water absorption and GFK 30°/60° has higher capability to absorb water than other orientations, Higher density explain the internal structure with low porous structure which has been confirmed due to low water absorption of this material.

Abstract: Risk to human health arising from intake of heavy metals in foods and water is of great concern, one of the major application of chitosan and its derivative is its ability to chelate strongly metal ions. This adsorption capacity could be increased by crosslinking or forming its nanocomposite. In this research study, chitosan/2,7 - naphthalenediol nanocomposite was formed, the nanocomposite was characterized using FTIR spectrophotometer and UV/Visible spectrophotometer. The adsorption of cadmium ion by the nanocomposite and chitosan alone was studied for comparison using CdCl2 solution containing Cd (II) ions. Amount of cadmium ion adsorb by each of them was studied at different time interval and evaluated using atomic absorption spectrophotometer (AAS). Results showed that chitosan/2,7 - naphthalenediol nanocomposite would adsorb maximum Cd2+ concentration of 0.017 mg/g at 20 minutes stirring time, while chitosan alone would adsorb maximum Cd2+ concentration of 0.016 mg/g at 10 minutes stirring time. It is therefore concluded from this study that both the chitosan and the nanocomposite have demonstrated almost the same degree of efficiency towards the removal of Cd2+ ion from aqueous medium and therefore both can be used in the treatment or removal of heavy metal ions from industrial effluents and other waste water.
