UNCERTAINTY CONTRIBUTIONS TO SPECIES SPECIFIC ISOTOPE DILUTION ANALYSIS
… (ICP-MS) for species specific isotope dilution mass spectrometry (IDMS). 199Hg enriched methylmercurychloride has been synthesised and recovered in the solid form for use as a spike material. The stability of methylmercury during the IDMS procedure was investigated using 199Hg and 13C …

The Mathematics behind Speciated Isotope Dilution Mass Spectrometry
Speciated Isotope Dilution Mass Spectrometry (SIDMS) allows researchers to measure the concentrations of species -- usually elemental -- in a sample by solving a system of non-linear equations. This thesis explores multiple mathematical methods to solve SIDMS equations, and compares the properties …

Translation of dilution tolerance for gasoline SI engine
… developed for spark ignition engines which use dilution. Many of these technologies use a combination of different diluents. It is impractical in optimizing these technologies to test every possible combination of diluents. The purpose of this study was to determine a relationship between the …

Quantifying entrainment and dilution in numerical simulations of developing thunderstorms
… hypothesized that greater entrainment (and thus dilution) occurs in stronger shear environments, but this relationship has not been suitably demonstrated with direct calculations of entrainment. This lack of understanding has consequences on the numerical weather prediction of convective …

A study of the effect of dilution rate on bacterial populations
… the atmosphere was studied at various constant dilution rates. Random fluctuations in the free swimmer population were noted. An aseptic continuous flow system proved of no great advantage over that which had ambient inoculation, however, slime production did not follow identical growth patterns …

Trademark Dilution : an Analysis of U.S., E.U., and East Asian Trademark Law.
The Lanham Act defines the term "dilution" as the lessening of the capacity of a famous mark to identify and distinguish goods or services, regardless of the presence or absence of competition between the owner of a famous mark and other parties, or likelihood of confusion, mistake or deception. …

Dilution acidosis : the effects of hyperosmolality on acid-base balance and ventilation
… a prolonged extracellular acidosis (so-called dilution acidosis), and a relative increase in extracellular Cl- concentration. In contrast, hyposmolality did not cause complementary changes in these variables. Studies in acute hyperosmotic stress were therefore undertaken to investigate both the …

The Effect of Nondiagnostic Information on Internal Auditor Skepticism: Capturing the Dilution Effect
… stereotypes of management, known as the dilution effect and attributed to the representativeness heuristic. Irrelevant information consistent with preconceived stereotypes does not decrease skepticism. In this experiment practicing internal auditors are provided an irrelevant description …

Constructing and Characterizing a Scanning SQUID Microscope for a Cryogen Free Dilution Refrigerator
… scanning SQUID microscope in a cryogen-free dilution refrigerator. First, I briefly describe basic SQUID theory, how to perform scanning SQUID microscopy, and how to design SQUIDs suited for microscopy. Next, I discuss both the apparatus and method to systematically characterize SQUIDs. I …

Global and Local Models for Dilution Factors: Theory and Stimulated Emission Pumping Experiments
The dilution factor is a measure of the intramolecular vibrational energy redistribution (IVR) an excited state undergoes. The distribution of dilution factors for a single molecule (SCCl2) was examined. Stimulated emission pumping (SEP) experiments were performed on SCCl2, probing the 7000--8,000 …

Dilution, corruption and redemption: authentic formative assessment in the subject classrooms of General Studies
This thesis investigates the implementation of formative assessment by student teachers in the 'figured world' of General Studies classrooms in Hong Kong. It aims to make suggestions for the effective preparation of student teachers in providing formative assessments in classrooms, and to provide …

Common = Ineffective? A Replication Attempt of the Normative Dilution Effect in the Context of Apologies
The normative dilution effect suggests that perceiving a behavior as normative can undermine its effectiveness, particularly in contexts where its communicative value matters. Intergroup apologies offer a compelling test case for this effect, as conveying sincere motives is key to their …

An Unsteady State Tracer Dilution Method for Characterizing Water Contributing Fractures in Crystalline Bedrock Wells

The rise and dilution of buoyant jets and their behaviour in an internal wave field
… in this thesis to simulate the trajectory and dilution of a fluid from a single port or line source. The new features include: A generalised derivation of the governing equations so that buoyant jets discharged from a source of any shape can be modelled within the one framework, and the effects …
