Experimental design and mathematical modelling methods for the study of anthelmintic resistance in UK livestock populations
… were assessed. For FECs obtained using sensitive counting techniques, percentage estimates are recommended to be evaluated using arithmetic group means. For FECs obtained by less sensitive counting techniques, the maximum likelihood estimator of zero inflated distributions is recommended when …

A new liquid scintillation counting technique to resolve mixtures of two pure beta-emitting radionuclides
… is based on elements of two liquid scintillation counting techniques that are widely used to measure single-radionuclide solutions, namely the triple-to-double coincidence ratio (TDCR) efficiency calculation technique and the CIEMAT/NIST efficiency tracing method. Double- and triple-coincidence …

A test of parity conservation in proton-proton scattering at 15 MeV
… the incident beam. The experiment used integral counting techniques to achieve the high data rate required. The Van de Graaff Lamh-shift polarized ion source was modified to permit reversing the direction of polarization at a 1 kHz rate. The experiment used analog signal processing; the …

Effect of Nonequilibrium Defects Due to Phase Transformation on Diffusion in Beta Zirconium
… samples were measured by serial sectioning and counting techniques. Appropriate correction methods were derived, for each set, to identify the proper interface because of the unique sectioning problems encountered.

A search for parity non-conservation in polarized proton-nucleon scattering at 6 GEV/C
… positive protons through an H20 target. integral counting techniques were used to achieve the high data rates required for the measurement of the small effect. We measured the cross section asymmetry (sigma+ - sigma_)/(sigma+ + sigma_) = (-26.3 +- 7.5) x 10-5 where sigma+ (sigma_) is the total …

Aspects of holography
… The real-time and double-exposure holographic techniques were used to investigate the objects. Hot air was employed as the stress application medium. The results obtained clearly show the viability of holography as a nondestructive testing technique for the detection of debonds, delaminations, …

Applying single-molecule localisation microscopy to achieve virtual optical sectioning and study T-cell activation
… still a matter of debate. Here, single-molecule counting methods are implemented to compare the stoichiometry of TCRs fused with mEos2 in resting T cells to monomeric and dimeric controls. However, because of the stochasticity of mEos2 photo-physics, results are inconclusive and new counting …

The Effects of a Combined Mathematics Content/Methods Course Involving Learning Cycles on Preservice Elementary Teachers' Beliefs about the Nature, Teaching and Learning of Mathematics
… percent, similarity and scale; and probability, counting techniques and statistics. Beliefs about the nature, teaching and learning of mathematics were measured both quantitatively and qualitatively. All participants' beliefs were assessed quantitatively at the beginning and the end of the course …

Effects of physical and chemical properties of bright and dull coal lithotypes on the formation of char particles
… scanning electron microscopy using image point-counting techniques. </p><p>PFBR tests and electron microscopy show that lithotype reactivity controls char morphologies, does not influence ash liberation in fluidized bed combustors, but may have an effect in other types of combustion. In …

Eulerian Properties of Design Hypergraphs and Hypergraphs with Small Edge Cuts
… than eulerian; in this thesis, we present some techniques that allow us to make the leap from quasi-eulerian to eulerian. A triple system of order n and index λ (denoted TS(n,λ)) is a 3-uniform hypergraph in which every pair of vertices lies together in exactly λ edges. A Steiner triple system …

Development of a System for Real-Time Measurements of Metabolite Transport in Plants Using Short-Lived Positron-Emitting Radiotracers
… Short-lived positron-emitting radiotracer techniques provide time-dependent data that are critical for developing models of metabolite transport and resource distribution in plants and their microenvironments. To better understand the effects of environmental changes on resource transport …
