Abstract: Environmental Ethics and Bioethics are two fast evolving sections of Applied Ethics. Issues that are related to Environmental Ethics and Bioethics include Cloning, Genetically Modified Organisms, and Euthanasia. Their teaching, despite two main constraints, is gradually introduced in the formal Educational System of various countries. The one constrain is the uncertainty that characterizes Environmental and Biological phenomena that creates gnoseological problems with regard to Life itself. The other is the natural complexity of the ethical dilemmas arising in these fields. Therefore, a problem that arises is to find the best way in order to teach these ambiguous issues. We are presently attempting to initially analyze these topics, in order to propose a new way to teach the above ambiguous issues.

Abstract: Since the Wild Free-Roaming Horses and Burros Act of 1971, debate has raged over whether horses and burros are restored North American natives. Fossil, genetic and archeological evidence supports these species as native. Also, objective evaluations of their respective ecological niches and the mutual symbioses of post-gastric digesting, semi-nomadic equids support wild horses and burros as restorers of certain extensive North American ecosystems. A Reserve Design strategy is proposed to establish naturally self-stabilizing equine populations that are allowed to harmoniously adapt over generations within their bounded and complete habitats. These populations should meet rigid standards for viability based on IUCN SSC assessments (2,500 individuals). Basic requirements are described for successful Reserve Design including viable habitat as well as specific regions of North America where this could be implemented.

Abstract: Exposure to radioactive elements or having them through drinking water causes many biological risks. Therefore, it is important to investigate the drinking water especially in regions where people depend on well water for drinking. Concentrations of some radionuclides in some water wells, in Arar city of Saudi Arabia, were measured by using Hyper Pure Germanium (HPGe) Detector. Concentrations of 226Ra (Radium), 232Th (Thorium) and 40K (Potassium) were measured in drinking water of 5 water Selling Stations from different water wells; Alshark, Alsahab, Ghdeer, Katr Elnada and Almohamadia. The radiation hazard indices of water were also calculated. The results showed that the average values of either radionuclides concentration or radiation hazard indices of all water stations under study were in the internationally permissible range. Results therefore emphasize that the investigated wells from which the water was taken are suitable for drinking concerning the measured radionuclides. The work recommends more studies to investigate another radionuclides might be present in the drinking water.

Abstract: A 56-day feeding trial involving 105 day old Anak broilers was carried out in a completely randomized design to evaluate, the performance, carcass yield and organ characteristics of broilers fed rumen epithelial scrapping meal (RESM a byproduct of cattle rumen processing that constitutes an environmental pollutant within the abattoir) at dietary levels of 0, 25, 50 75 and 100%. Results show that the feed efficiency of 50, 75 and 100% RESM were superior to the control and 25% inclusion at the starter phase but at the finisher phase the control was superior over the other treatments and the average final weight gain of the control at the finisher phase was superior (P<0.05) over all other treatments though all the birds attained a weight of over 2kg at the end of the 56day trial. The dressing% and eviscerated% of 100% RESM was superior to all other treatments though not (P>0.05) significantly different, while the eviscerated weight (kg) of 25% RESM was superior to all other treatments. The internal organs (% Eviscerated Weight -EW) were all similar except for the heart where the control was significant (P<0.05) over all other treatments while in the cut up parts (% EW) there was no significant difference (P>0.05) among the parts such as wing, head, drum stick, thigh weight, breast weight, except the back weight where the control, 25%, and 50% show significant difference (P<0.05) over the other treatments, though the control and 50% showed similarity to 75 and 100% treatment levels. Overall, no particular trend emerged indicating that RESM could be used to replace fishmeal without any adverse effect both to the birds and the final consumers since it is consumed in some parts of the country.

Abstract: The study was conducted to assess the prevalence of Hepatitis B surface antigen (HBsAg) among the newly admitted students of University of Jos, Jos Nigeria. A total of 300 newly admitted students were screened using rapid test (Global Rapid Diagnostic Kits USA) for the detection of HBsAg in serum samples from July 2010 to October 2010. The results obtained showed that 50(16.7%) were seropositive to HBsAg. The prevalence of HBsAg was higher in males 34(11.33%) compared to 16(5.33%) in females. Age specific prevalence was significantly higher in the age bracket 25-29, with 16(28.57%) and the lowest was found in the age bracket 15 -19 years with 12(17.39%). The most important risk factors in the acquisition of HBsAg as revealed in this study appear to be: Family History of hepatitis, 11(36.6%), those with multiple sexual partners 4(13.79%), blood transfusion 3(13.64%), and tribal mark 3(13.04%). The prevalence of HBV recorded among newly admitted students in this study is probably a reflection of the situation in Nigerian Universities. Therefore, urgent preventive measures should be taken to set up campaign against transmission of HBV in University of Jos and the general population. To lower HBV prevalence, an adequate program of active screening and vaccination for students should be implemented, followed by a universal active immunization program.
