Biological Aerated Filters: Oxygen Transfer and Possible Biological Enhancement
A submerged-media biological aerated filter (BAF) has been studied to 1) evaluate oxygen transfer kinetics under conditions without biological growth and 2) determine the influence of biological growth on the rate of oxygen transfer. Collectively, the study evaluates the rates of supply and …

Switchable biological surfaces
… monolayers (SAMs) has many potential biological and medical applications. The aim of this project was to produce mixed biotinylated peptide monolayers that are responsive to an electric potential, thus providing a system in which the conformation of the biotinylated peptides could be …

New Biological Pathways
… by using microscopic – often designed – biological components, allowing biology to conduct highly specialized forms of work previously unseen in nature. In this thesis, I propose and develop three new biological pathways which can perform three different categories of work i) information …

Platforms for Biological Control
Innovation at the level of platforms provides the greatest leverage for shaping science and technology. Here, two key weaknesses in platforms for biology are addressed: the lack of accessible, extensible open-source software for the exploding field of robotic bioautomation, and the lack of a …

Large-scale biological transportation networks
Großskalige Tierbewegungen und Transportsysteme besitzen oft eine inheränte Netzwerkstruktur und können leicht als Bewegungsereignisse zwischen diskreten Regionen modelliert werden. Das Ziel dieser Arbeit besteht in der Entwicklung und Beschreibung von Transportnetzwerken, die zum Einen den …

Inertial manifolds in biological systems
The focus of this thesis is biological systems whose dynamics present an interesting feature: only some dimensions drive the whole system. In our examples, the dynamics is expressed as ODEs, such that the ith equation depends on all the variables xi = f (x1,...,xi,xi+1,...), so that they cannot be …

Computer Simulation of Biological Systems
This thesis investigates two biological systems using atomistic modelling and molecular dynamics simulation. The work is focused on: (a) the study of the interaction between a segment of a DNA molecule and a functionalized surface; (b) the dynamical modelling of protein tau, an intrinsically …

Characterization of biological hydrogel barriers
Biological hydrogel barriers include mucus, bacterial biofilms, fungal biofilms, and others. Biofilms are polysaccharide hydrogels. Biofilms are commonly found in the lungs of cystic fibrosis patients. Cystic fibrosis (CF) patients are susceptible to these types of chronic infections because their …

Biological Indicators of Forest Dieback
This study involved the determinations of the foliar levels of chlorophyll a and b and metal levels in the year 1, year 2 and year 3 needles of Sitka spruce. A survey was made of nineteen sites in the Afan 1 forest in South Wales. The results obtained indicates that there are two distinct types of …

Light localization in biological media
Light in natural and biological media is known as freely diffusing. When light undergoes multiple scattering through inhomogeneous dielectric biomacromolecules, interference is ignored. If scattered waves return to their origin points along the time-reversed paths for constructive interference, …

Biological activity of Sinularia notanda
… variety of cembrane diterpenoids with a range of biological activities are reportedly isolated from marine soft coral, and most notably these compounds possess anticancer properties. The investigation of a marine soft coral, Sinularia notanda, for novel bioactive compounds is presented here. The …
