Formation of (halo)acetamides and (halo)acetonitriles from the reaction of monochloramine and (halo)acetaldehydes in water
… by-products (DBPs) that include four trihalomethanes and five haloacetic acids. However, recent research suggests that unregulated nitrogen-containing DBPs formed by combined chlorine, such as haloacetonitriles and haloacetamides, might be more toxic than regulated DBPs. Monochloramine …

Chemodynamics of the Galactic Halo
… in the galaxy. Namely, how dark matter subhaloes, the bar, and the Large Magellanic Cloud can influence the phase space characteristics of the merger debris. Chapters 5 and 6 explore the dynamics of one of the Milky Way's main dwarf galaxies -- the Sagittarius dwarf spheroidal. Specifically …

Dynamische Stabilisierung von Hochgeschwindigkeitswolken im galaktischen Halo
… cloud in a hot, thin, and magnetized ambient halo plasma is addressed. The results of two-dimensional plasma-neutral gas simulations showing the dynamical evolution of neutral gas clouds in a plasma flow are presented. The simulations show the formation of a comet-like head-tail structure …

Halo- and organogold(I) complexes as potential metallomesogens
There is currently much interest in how the properties of liquid crystals may be altered by metal atoms. Gold(I) complexes of the type RAuL have recently been shown to exhibit interesting liquid crystal behaviour. As molecular structure and intermolecular forces play a major role in liquid crystal …

HALO : re-forming architectural space with light caustics
What form can light take? Light has been an eternal theme in architectural design. Light defines, shapes, and transforms space in various ways. However, the way light has been used in human history has not changed: the variation of space is a result of the interaction between light and shadow along …

An improved RF cavity search for halo axions
… matter candidate. In this RF cavity experiment, halo axions entering a resonant cavity immersed in a static magnetic field convert into microwave photons, with the resulting photons detected by a low-noise receiver. I present new limits on the axion-to-photon coupling and local axion dark matter …

Formation and dynamics of the Galactic disc and halo
… interpreted dynamically. The disc, the bar, the halo and the satellites are all components of the Galaxy's dynamical system which are able to interact to create, perturb and destroy substructure. By using tailored and cosmological simulations, this substructure can be modelled and interpreted to …

Halo-fosfatų 31P, 1H ir 35Cl kietojo kūno BMR tyrimas /
Calcium phosphates (CaPs) are a family of materials used for various applications such as bone regeneration, catalysis, 3D printing, development of optical materials, etc [1]. Properties such as bioactivity, biocompatibility and osteoconductivity are necessary for CaPs in bioapplications [1, 3]. …

The Ontology of the Venetian Halo in its Italian Context
This thesis aims to reposition the halo’s status within an artwork through arguing a reassessment of its activity 'as a sign' rather than acceptance of its passivity. This active state is further explored and expanded by a heuristic application of semiotic theory to interrogate its fluctuation …

Interplanetary Transfer Trajectories Using the Invariant Manifolds of Halo Orbits
… rather than just one. The invariant manifolds of halo orbits about Sun-planet Lagrange points are used to aid in the transfer from one planet to another, and can lead into orbital insertion about the destination planet or flyby trajectories to get to another planet. This work uses this method of …

Statistics of the Dark Matter Halo Distribution in Cosmic Density Fields
… Klumpen aus dunkler Materie (dunkle Halos). Obwohl die hydrodynamischen Prozesse, die an der Entstehung von Galaxien beteiligt sind, noch wenig verstanden sind, wird angenommen, daß diese Prozesse für die Entstehung einzelner Objekte relevant sind und daß sie möglicherweiser keine …

Which creates the bigger halo: cause-related marketing or cause-sponsorship?
… This study tests the benefits of a positive halo effect from CSR campaigns and explores the role of involvement in the relationship. A halo effect can be described as a cognitive bias in which one trait can positively affect the subsequent perceptions of a brand (Madden et al., 2012), and …

A Comparison of Autonomous Navigation Methods for Earth-Moon Halo Orbits
… method. These six test cases were a selection of halo orbits in the Earth-Moon system (a set of sensitive orbits dependent on Earth-Moon dynamics). We simulated the true state information for each of these test cases for a period of 30 days. We also simulated the true values of the measurements …
