The kinetics of the partitioning of lipid vesicles containing acidic phospholipids in aqueous two-phase polymer systems are dependent upon the vesicle size; the larger the vesicles, the more readily they absorb to the interfaces between the two polymer phases and hence are cleared from the top phase as phase separation proceeds. The partitioning of neutral lipid vesicles is principally to the b...

Phenols are a major class of volatile organic compounds (VOC) whose reaction within, and partitioning between, the gas and liquid phases affects their lifetime within the atmosphere, the local oxidising capacity, and the extent of production of nitrophenols, which are toxic chemicals. In this work, a zero-dimension box model was constructed to quantify the relative importance of different nitra...

Gas-phase concentrations of semi-volatile organic compounds (SVOCs) were calculated from gas/particle (G/P) partitioning theory using their measured particle-phase concentrations. The particle-phase data were obtained from an existing filter measurement campaign (27 January 2003-2 October 2005) as a part of the Denver Aerosol Sources and Health (DASH) study, including 970 observations of 71 SVO...

This paper presents some implementation details of a threephase to three-phase matrix converter prototype. The bidirectional semiconductor switches were built using discrete IGBTs and fast diodes.

An importantpresuppositionfor HW/SW partitioning aresophisticated estimation algorithms at a high level of abstraction that obtain high quality results. Therefore the granularities of estimation and partitioning have to be adapted adequately. In this paper we discuss the effects that arise when the granularities of partitioning and estimation are not adapted in a necessary way. Furthermore we p...

The diversity of predatory species plays a key role in ecosystem functioning but our understanding the mechanisms underlying their coexistence is limited, particularly freshwater ecosystems. Northern pike Esox lucius, European perch Perca fluviatilis and pikeperch Sander lucioperca are three widespread lakes, where they often coexist. As potential competitors, we hypothesised that partitioning ...
