An investigation of factors influencing the bioavailability of silver nanoparticles within a terrestrial system
… silver nanoparticles are lacking, especially in terrestrial systems. A series of experiments were devised in order to determine which soil properties and which nanoparticle characteristics had the most significant impact on bioavailability to plants and insects. Plants and invertebrates make up …

Experimental transmission of dispersion managed solitons
… transmission over sufficient distance for an terrestrial system. Also contained within this thesis are experimental results showing transmission of solitons over dispersion shifted fibre using a novel technique that makes use of the non-linear polarisation rotation of the soliton in the fibre. …

A model of a rangeland grazing system within a management procedure approach framework
A model describing livestock grazing system dynamics was developed and fitted to available data. This study preliminarily explored the use of a formal management procedure (MP) approach to determine appropriate annual offtake in a terrestrial system. This approach has been applied in marine systems …

A Connection Admission Control Framework for UMTS based Satellite Systems.An Adaptive Admission Control algorithm with pre-emption control mechanism for unicast and multicast communications in satellite UMTS.
… the use of multimedia applications. A satellite system offers great potential for multimedia applications with its ability to broadcast and multicast a large amount of data over a very large area as compared to a terrestrial system. However, the limited transmission capacity along with the …

Quantifying mercury surface fluxes by combining atmospheric observations and models
… the ocean contributes about a half. The global terrestrial ecosystem is found to be neither a net source nor a net sink of Hg⁰ (gaseous elemental mercury). The optimized Asian anthropogenic emissions (0.7-1.8 Gg yr-¹) are very likely higher than bottom-up estimates, implying missing sources, …

Tracking carbon fluxes across ocean interfaces using dissolved gas observations
… cycling and exchange of carbon between Earth’s systems play a pivotal role in regulating climate, yet two major carbon fluxes remain poorly constrained: the biological carbon pump (BCP) and carbon release from Arctic permafrost. This thesis focuses on dissolved gases as tracers and drivers of …

Influences of Mountainside Residential Development to Nutrient Dynamics in a Stream Network
… services (e.g., water supply) to downstream ecosystems and human communities. Fast-growing mountainside residential development not only modifies the terrestrial system but also aquatic systems by changing the nutrient input from the terrestrial to aquatic. However, the impacts of mountainside …

Coevolutionary dynamics under anthropogenic impact in intensively managed landscapes
… Soil is the largest reservoir of carbon in the terrestrial system but is going through rapid erosion due to anthropogenic influences. The soil erosion and resultant landscape evolution plays a vital role on the soil-atmosphere C exchange. Here, we develop a process-based quasi 3-D model, named …

New sharing method between the Fixed Satellite Service and the Aeronautical Mobile Satellite Service in the 14.0-14.5 GHz band
… satellite network with a satellite and a movable terrestrial non-aeronautical earth station. An example of an LMSS is a system called Omnitracs, which provides a satellite-based data connection for the trucking industry. AMSS stands for the Aeronautical Mobile Satellite Service. An AMSS is an LMSS …
