Interactions between anticholinesterases in an in vitro central nervous system preparation
… as chemical warfare agents (nerve agents, e.g. sarin). These compounds rapidly inhibit the enzyme acetylcholinesterase (AChE), causing overstimulation within the cholinergic nervous system. If left untreated, this can be fatal. Current medical countermeasures to nerve agent poisoning consist of …

Computational Investigations at the Gas-Surface Interface: Organic Surface Oxidation and Hydrolysis of Chemical Warfare Agents and Simulants
… gas-surface reaction pathway of the nerve agent Sarin on the Lindqvist polyoxoniobate Cs8Nb6O19, we determined that the rate-limiting step is the transfer of a proton from an adsorbed water molecule to the niobate surface, concomitant with the nucleophilic addition of the nascent hydroxide to the …

Untersuchungen zur schnellen Freigabe von HI-6 Dichlorid und HI-6 Dimethansulfonat aus verschiedenen Autoinjektorsystemen. Neue Aspekte des Stabilitätsverhaltens dieser Salze und ihrer ungepufferten, konzentrierten Lösungen.
… in cases of life-threatening poisoning by sarin, VX or cyclosarin. About 1.0 mmol of such a bispyridinium salt concomitantly given with 2 mg atropine is sufficient for first aid. Because of its instability in water, combinations of dry HI-6 powder with atropinesulfate solutions are …

Development of a phosphotriesterase enzyme assay for determination of organophosphate pesticides
… and parathion and nerve toxins such as soman and sarin. This project resulted in the development of novel phosphotriesterase enzyme assays to measure paraoxon and other representatives of the organophosphate pesticides. The assay is based on a substrate-dependent change in pH at the local vicinity …

Ionic Liquids Tethered to Activated Carbon for Capture of Airborne Toxins
… in gas capture investigations as a model for sarin gas. In order to understand the impact of the cation-anion pair selection in the IL, DMMP absorption tests were conducted in neat ILs. This was done by flowing argon saturated in DMMP through the ionic liquids and monitoring the DMMP detection …

Enzyme and Directed Evolution Technologies For Nerve Agent Neutralisation
… the chemical warfare agents DFP, Dimefox, Tabun, Sarin, Cyclosarin, Soman, VX, and Russian-VX . These chemical surrogates have a similar structure but do not share the same physico-chemical properties as the nerve agents themselves. The directed evolution platform developed and used consisted of …

Memory struggles: Narrating and commemorating the Aum Affair in contemporary Japan, 1994-2015
… in the gassing of the Tokyo subway system using sarin in March 1995. The Tokyo attack was the largest act of terrorism in post-war Japan. I combine qualitative methods of media analysis, interviews, and participant observation to analyse how different stakeholders have narrated and commemorated …

Ring-opening Metathesis Polymerization for the Creation of Responsive Colloids and Surfaces
… to various chemical-warfare-agents, including Sarin and Mustard Gas. In Chapter 5, a sterically hindered cyclobutene is synthesized as a potential ROMP monomer and its polymerization reactivity is explored. This cyclobutene is further epoxidated to give a highly reactive cyclobutane epoxide, of …

Leben als Artikulation : die anthropologische Ikonographie der Schriften von Imre Kertész
Imre Kertész ist 1929 in Budapest geboren und dort aufgewachsen. 1944 wurde er im Rahmen einer Judendeportation verhaftet und über Auschwitz in das KZ Buchenwald verbracht. Nach der Befreiung des Lagers 1945 kehrte er in seine Heimatstadt zurück, wo er seit 1953 als Schriftsteller und Übersetzer …

Iron Release From Corrosion Scales in Old Iron /Steel Drinking Water Distribution Pipes
A conceptual model was developed to address the issues of the formation and growth of iron corrosion scales, and their reactions that lead to colored water problems. According to the model, iron release from corrosion scales can be controlled, in general, by either (a) promoting a denser scale …

Efficient Iterative Methods for Saddle Point Problems
This thesis investigates efficient iterative methods for a type of saddle-point problem, namely the generalized Stokes problem, which arises frequently in the simulation of time-dependent Navier-Stokes equations for incompressible fluid flow. These systems are indefinite due to a set of linear …

Equitable economic energy efficiency : creating good jobs in low-income efficiency programming
Energy efficiency is an important consideration in energy policy-making. So, a federal program aimed at funding "energy efficiency retrofits" for low-income households could be an important step in increasing the overall efficiency of energy use in America. If each eligible household reduces the …

Liquid transport mechanisms in cotton-polypropylene laminated nonwoven fabrics influencing pesticide penetration
The purpose of this research was to investigate and compare the liquid transport properties of cotton nonwoven laminates of varying cotton/polypropylene fiber content (80:20, 60:40, 40:60, by weight) with a 100% polypropylene fabric and a 100% polyethylene fabric. Capillary, pressure and impact …

Interactions of investment opportunities and financing decisions
This study examines how the investment opportunity set of the firm affects financing choices the firm makes. In a two-period, one decision, no-tax model, we show that firms characterized by a high level of investment opportunities in future periods issue equity and convertible securities while …

Investigation of Closed-Loop Control of Polyatomic Molecules
… (DMMP), a simulant for nerve agent Sarin. The exploitation of the sensitivity of molecular fragmentation to laser pulse shapes represents a new way to discriminate molecular identity. Here we have shown manipulation of the branching M-(OCH3)+/M-(CH3)+, M-2(CH3)+/M-(CH3)+ and …

Essays on pricing and learning in Bertrand markets.
… generalized payoff assessment learning model of Sarin & Vahid (1999) for the perfect information Bertrand experiments we studied in Chapter 1. The model contains the quantal-response adaptive learning model of Chapter 1 and the original payoff assessment learning model as special cases. A main …

Ultrahigh Vacuum Studies of the Fundamental Interactions of Chemical Warfare Agents and Their Simulants with Amorphous Silica
… provided by the simulant studies, the CWA, Sarin is predicted to adsorb to isolated hydroxyl groups of the silica surface via the phosphoryl oxygen with a strength of 53 kJ/mol. The interactions of two common mustard simulants, 2-chloroethyl ethyl sulfide (2-CEES) and methyl salicylate …

The Decolonization of the Political Economy of New Media Institutions in Africa: A Case Study on the Pan-African Film Industry
This study critically analyses an alternative political economy framework to observe the decolonization of new media institutions in Africa. This is because "critically analysing media organisations and media processes in society have come from political economy perspectives." (Jansen, 2003, p. …
