Water markets are developing as part of a Council of Australian Governments initiative to promote an efficient use of Australia's water resources. The consequences of these policies on river health is yet to be fully understood, but recognised as having significant interrelationships which need to be explored. This paper examines the consequences of introducing trade and allocating water for en...

In this paper we describe an extractive method of creating very short summaries or gists that capture the essence of a news story using a linguistic technique called lexical chaining. The recent interest in robust gisting and title generation techniques originates from a need to improve the indexing and browsing capabilities of interactive digital multimedia systems. More specifically these sys...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

An extractive bioconversion with Bacillus cereus cyclodextrin glycosyltransferase (CGTase, EC 2.4.1.19) in aqueous two-phase system (ATPS) was investigated for the synthesis and recovery of cyclodextrins (CDs). Optimum condition for the extractive bioconversion of CDs was achieved in ATPS consisted of 7.7% (w/w) polyethylene glycol (PEG) 20,000 and 10.3% (w/w) dextran T500 with volume ratio (VR...

In this paper we explore the benefits from and shortcomings of entity-driven noun phrase rewriting for multidocument summarization of news. The approach leads to 20% to 50% different content in the summary in comparison to an extractive summary produced using the same underlying approach, showing the promise the technique has to offer. In addition, summaries produced using entity-driven rewrite...

Extractive distillation is one of the efficient techniques for separating azeotropic and low-relativevolatility mixtures in various chemical industries. This paper first provides an overview of thermodynamic insight covering residue curve map analysis, the application of univolatility and unidistribution curves, and thermodynamic feasibility study. The pinch-point analysis method combining bifu...

We study a model of institutions that evolve through con ict. We nd that one of three con gurations can emerge: an extractive hegemony, a balance of power between extractive societies or a balance of power between inclusive societies. As extractive societies are assumed to have an advantage in head to head confrontations we refer to the latter possibility as the survival of the weakest. Our con...

Ionic liquids (IL) and hyperbranched polymers (HyP) represent new classes of nonvolatile selective solvents. By measuring vapor-liquid equilibria (VLE) of azeotropic and close boiling systems in the presence of ionic liquids or hyperbranched polymers, separation factors are derived and the potential of using IL and HyP as entrainer for extractive distillation is discussed. Exemplarily, the supe...

The structure of thermally coupled distillation systems offers several control challenges arising from the transfer of vapor (or liquid) streams between columns. In particular, the presence of recycle streams for coupled schemes has led to the notion that control problems might be expected during the operation of these systems, in contrast to the rather well-known behavior of conventional disti...
