Towards a more ethical military : the contribution of Aristotelian virtue theory to military ethics
textThe protracted wars in Afghanistan and Iraq have led to a number of moral abuses committed by members of the U.S. military. Media reports have focused particular attention on the human cost incurred by these abuses, the torture of detainees at Abu Ghraib and the massacre of civilians at Haditha being but a few, tragic examples. However, the human cost of these abuses is measured not just in the lives of noncombatants, but also by the number of military suicides that are a byproduct of traumatic combat experiences and the subsequent violation of moral norms. In light of this, any society that is sincere in its concern for the moral well-being of its soldiers, and the noncombatants with whom they interact, should seek to reduce the occurrence of such abuses. In this dissertation, I argue that the development of moral character, particularly the conception of moral character that Aristotle promotes in his ethical theory, is fundamental to preventing the moral abuses that soldiers commit, both in combat and during peacetime. This project is composed of five chapters. The first chapter is devoted to describing the moral challenges that confront soldiers, particularly on the battlefield. Chapter Two articulates the broad outlines of Aristotelian virtue ethics with a specific emphasis on four key features of Aristotle’s virtue theory and how they can be harnessed to promote ethical conduct within the military institution. Arguably, the most important component of moral character is practical reason, the ability to assess a moral problem, weighing all the various considerations that affect it, and arrive at an ethical solution. Considering this, Chapter Three examines how practical reason can guide the soldier’s understanding of obedience, loyalty and respect, traits that are widely considered military virtues, but which are also at the root of a great deal of unethical behavior. Chapter Four examines the military’s code of professional ethics and how the possession of practical reason is necessary if soldiers are to make ethical decisions in situations the code does not explicitly address. The final chapter, Chapter Five, argues for more emphasis on the development of practical reason in military ethics education.Philosoph

Removal of Mercury from the Off-Gas from Thermal Treatment of Radioactive Liquid Waste
Acidic, radioactive wastes with a high nitrate concentration, and containing mercury are currently being stored at the Idaho Nuclear Technology and Engineering Center (INTEC). In the past, these wastes were converted into a dry, granular solid by a high temperature fluidized-bed calcination process. In the future, the calcined solids may be immobilized by a vitrification process prior to disposal. It has been proposed that a vitrification facility be built to treat the acidic wastes, as well as the calcined solids. As was the case with the calcination process, NOx levels in the vitrification off-gas are expected to be high, and mercury emissions are expected to exceed the Maximum Control Technology (MACT) limits. Mitigation of mercury emissions by wet scrubbing, followed by adsorption onto activated carbon is being investigated. Scoping tests with sulfur-impregnated activated carbon, KCl-impregnated activated carbon and non-impregnated activated carbon were conducted with a test gas containing1% NO2, 28% H2O, 4% O2 and 67% N2. Average removal efficiencies for Hgo and HgCl2 were 100 ± 2.5% and 99 ± 3.6% respectively, for sulfur-impregnated carbon. The KCl-impregnated carbon removed 99 ± 4.6% HgCl2. The removal efficiency of the non-impregnated carbon was 99 ± 3.6% for HgCl2. No short-term detrimental effects due to NO2 and H2O were observed. These results indicate that, placed downstream of a wet scrubber, an activated carbon adsorption bed has the potential of reducing mercury levels sufficiently to enable compliance with the MACT limit. Long-term exposure tests, and bed size optimization studies are planned for the future
Summary of TRUEX Radiolysis Testing Using the INL Radiolysis Test Loop
The INL radiolysis and hydrolysis test loop has been used to evaluate the effects of hydrolytic and radiolytic degradation upon the efficacy of the TRUEX flowsheet for the recovery of trivalent actinides and lanthanides from acidic solution. Repeated irradiation and subsequent re-conditioning cycles did result in a significant decrease in the concentration of the TBP and CMPO extractants in the TRUEX solvent and a corresponding decrease in americium and europium extraction distributions. However, the build-up of solvent degradation products upon {gamma}-irradiation, had little impact upon the efficiency of the stripping section of the TRUEX flowsheet. Operation of the TRUEX flowsheet would require careful monitoring to ensure extraction distributions are maintained at acceptable levels
Characterization of radiolytically generated degradation products in the strip section of a TRUEX flowsheet
This report presents a summary of the work performed to meet the FCRD level 2 milestone M3FT-13IN0302053, “Identification of TRUEX Strip Degradation.” The INL radiolysis test loop has been used to identify radiolytically generated degradation products in the strip section of the TRUEX flowsheet. These data were used to evaluate impact of the formation of radiolytic degradation products in the strip section upon the efficacy of the TRUEX flowsheet for the recovery of trivalent actinides and lanthanides from acidic solution. The nominal composition of the TRUEX solvent used in this study is 0.2 M CMPO and 1.4 M TBP dissolved in n-dodecane and the nominal composition of the TRUEX strip solution is 1.5 M lactic acid and 0.050 M diethylenetriaminepentaacetic acid. Gamma irradiation of a mixture of TRUEX process solvent and stripping solution in the test loop does not adversely impact flowsheet performance as measured by stripping americium ratios. The observed increase in americium stripping distribution ratios with increasing absorbed dose indicates the radiolytic production of organic soluble degradation compounds

Idaho Nuclear Technology and Engineering Center Sodium-Bearing Waste Treatment Research and Development FY-2002 Status Report
The Idaho National Engineering and Environmental Laboratory (INEEL) is considering several optional processes for disposal of liquid sodium-bearing waste. During fiscal year 2002, immobilization-related research included of grout formulation development for sodium-bearing waste, absorption of the waste on silica gel, and off-gas system mercury collection and breakthrough using activated carbon. Experimental results indicate that sodium-bearing waste can be immobilized in grout at 70 weight percent and onto silica gel at 74 weight percent. Furthermore, a loading of 11 weight percent mercury in sulfur-impregnated activated carbon was achieved with 99.8% off-gas mercury removal efficiency

Biomaterial bridges enable regeneration and re-entry of corticospinal tract axons into the caudal spinal cord after SCI: Association with recovery of forelimb function
Severed axon tracts fail to exhibit robust or spontaneous regeneration after spinal cord injury (SCI). Regeneration failure reflects a combination of factors, including the growth state of neuronal cell bodies and the regeneration-inhibitory environment of the central nervous system. However, while spared circuitry can be retrained, target reinnervation depends on longitudinally directed regeneration of transected axons. This study describes a biodegradable implant using poly(lactideco-glycolide) (PLG) bridges as a carrier scaffold to support regeneration after injury. In order to detect regeneration of descending neuronal tracts into the bridge, and beyond into intact caudal parenchyma, we developed a mouse cervical implantation model and employed Crym:GFP transgenic mice. Characterization of Crym:GFP mice revealed that descending tracts, including the corticospinal tract, were labeled by green fluorescent protein (GFP), while ascending sensory neurons and fibers were not. Robust co-localization between GFP and neurofilament-200 (NF-200) as well as GFP and GAP-43 was observed at both the rostral and caudal bridge/tissue interface. No evidence of similar regeneration was observed in mice that received gelfoam at the lesion site as controls. Minimal co-localization between GFP reporter labeling and macrophage markers was observed. Taken together, these data suggest that axons originating from descending fiber tracts regenerated, entered into the PLG bridge at the rostral margin, continued through the bridge site, and exited to re-enter host tissue at the caudal edge of the intact bridge. Finally, regeneration through implanted bridges was associated with a reduction in ipsilateral forelimb errors on a horizontal ladder task
Floodplain management strategies in the intermountain West
posterFlooding is the most frequent severe weather threat and the nation's costliest natural disaster. Ninety percent of natural disasters in the U.S. involve flooding. Floodplains often get overlooked until these events happen, leaving areas vulnerable and susceptible to flooding events. Floods are predicted to become more severe but less frequent, making planning for these events vital. Many communities live in false security as they haven't had any major flooding in years and do not expect flooding to occur. When floods happen in ill-prepared communities, property damage will be severe, and deaths will occur. Buildings can be replaced, but lives cannot; places must work to protect buildings and lives
