Synthesis of monodisperse silver nanoparticles for antibacterial purposes by Adam, Sarah

“…Additionally, the presence of large nanoparticles in both samples, as evidenced from the volume-based size distributions, means that in assessing antibacterial activity of the nanoparticles, it will be difficult to interpret whether the bactericidal effect is due to silver ions or because of an interaction between the bacteria and the actual nanoparticles. …”

Fractional-N PLL-Based Waveform Synthesis for FMCW SAR by Gwasira, Thomas

“…Furthermore, the signal acquisition system was redesigned to increase the data rate of the system from 11 MB/s to 43.231 MB/s, thus, allowing support for higher PRFs and sample rates. Frequency response characteristics involve stability of both the synthesiser and the generated waveforms. …”

The relationship between various risk factors and the cost of equity premium implied by analysts' forecasts on the New York Stock Exchange by Goussard, Heleen

“…This study, an implementation of Arbitrage Pricing Theory, attempts to create a parsimonious model of factors that are associated with the implied cost of equity premium utilised by equity analysts on the New York Stock Exchange ("NYSE"). After limiting the sample to NYSE-listed companies that were primarily exposed to US macro-economic conditions and were likely to be valued overwhelmingly on a going-concern basis, the test sample consisted of 5,343 company quarters covering the period 2006 to 2015. …”
