The Effects of Dilutions and Payout Policy on Equity- and Stock-linked Call Options on a Firm with Leverage
… et al. (2022) also allows for the effects of dilutions and buyback policy on stock-linked options to be explored. Using the framework developed by Backwell et al. (2022) with asset value dynamics presented by Leland (1994), the capital-debt structure of a firm is modelled. Finitedifference …

A study on the effect of dilutions and buybacks on the pricing of equity and stock based claims using a finite difference mesh
We study a model of the firm, with perpetual debt and a continuously payable coupon as well as the possibility to raise cash via equity issuance. Excess cash is paid back to shareholders either via dividends or via buybacks. The number of shares changes when equity is issued and when the firm buys …

The development of differential media for the isolation of proteolytic bacteria from the rumen
… for the study of proteolytic organisms. Dilutions of rumen contents to 1 x 10⁻⁸/ml were made in anaerobic dilution fluids. Cultures were grown in roll tubes or bottles containing CO₂ atmosphere. All of the media used in this study repeatedly produced an average count of 40 colonies per …

Localization and delocalization in two-dimensional quantum percolation
… phase diagram for energies 0.001 ≤ E ≤ 1.6 and dilutions 2% ≤ <em>q</em> ≤ 38%. Additionally, I show that the delocalized phase is not merely a finite size effect. In Chapter 3, I examine the same 2D quantum percolation model on highly anisotropic strips of varying width, to investigate why the …

Properties of Three Plasmids Isolated From Plant Pathogenic Pseudomonads
… symptoms on host and nonhost plants when serial dilutions of bacteria were injected directly into leaf tissue. Also, cured and plasmid-containing isolates of P. tabaci 11528 and P. tabaci BR2 produced approximately the same amount of tabtoxin. These data indicate that pJP1, pBPW1, and pJP30 do …

Optimizing main spectrum profiles for use in real-time MALDI-TOF mass spectrometry identification of Leptospira serovars
… MSP specificity was tested using serial dilutions of serovar culture and culture spiked canine urine. Specificity of these original MSPs was found to be insufficient for accurate and consistent serovar identification. Various MALDI sample preparation and deposition methods were tested to …
