Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
In this study, an investigation of long-term forecasts relating to the development of the transport sector in Poland is performed, including the ones by 2030 and 2050. Selected transport development forecasts from the perspective of the membership of Poland in the European Union are presented and most of all, from the perspective of national studies. The basement for the review was the prognosi...

In February 2002, the Institute of Transport Studies (ITS), The University of Sydney, initiated a study to investigate world class logistics (WCL) practices in Australia. This research is part of the wider WCL study investigating the state of quality practices in logistics in Australian companies. The study examines the extent to which quality management practices are adopted, impediments to im...
The popularity of stated choice (SC) experiments has spurned a large number of design strategies within which to study choice behaviour. When the amount of information provided increases, we often wonder how an individual handles such information in making a choice. Defining the amount of information (or ‘complexity’) as the product of the number of attributes and number of alternatives associa...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
