Coupled SFE}SFC has shown itself to be a very useful technique for those samples for which it is applicable. The ability to transfer all the extract to the analytical column without manipulation increases sensitivity, reduces contamination and sample handling. The overloading of capillary columns is avoided. Now that methods for using modiRers in the extraction solvent and SFE sample injection ...

Context. Star formation efficiency (SFE) theories are currently based on statistical distributions of turbulent cloud structures and a simple model of star formation from cores. They remain poorly tested, especially at the highest densities. Aims. We investigate the effects of gas density on the SFE through measurements of the core formation efficiency (CFE). With a total mass of ∼2 × 104 M , t...

Low-complexity blind turbo receivers composed of a soft-feedback equaliser (SFE) and fast least-squares (FLS) channel estimators are proposed. To reduce the complexity of the SFE computation, a function approximation is proposed instead of numerical algorithms in a specific step of the equaliser’s computation. Concerning FLS channel estimators, a specific filter parameters initialisation proced...

In their paper, “Rational Secure Computation and Ideal Mechanism Design,” Izmalkov, Lepinski and Micali show that any one-shot mediated game can be simulated by the players themselves, without the help of a trusted mediator, using physical envelopes and a ballot-box. We show that communication between the players is not essential to the ILM protocol. That is, we provide a protocol for rational ...

Deformation microstructure and texture in a cold-rolled austenitic steel 310S with low stacking fault energy (SFE) have been investigated by SEM and TEM. When 310S plates were rolled by 95% in thickness reduction, a remarkable development of the brass-type preferred orientation was confirmed by X-ray diffraction. SEM observations of the specimens with such texture exhibited a layered structure ...

Temperature and pressure effects of supercritical carbon dioxide (SCCO2) on the extraction of carotenoids and seed oil from rosehip fruits have been studied. Supercritical fluid extraction (SFE) has shown much potential skills for the isolation of organic compounds from various samples. SFE minimizes sample handling, provides fairly clean extracts, expedites sample preparation and reduces the u...

Ferulate-mediated lignin/hemicellulose cross linking in grasses reduces in vitro NDF digestibility (IVNDFD). Impact of ferulate cross linking on animal performance was examined in lamb digestibility and dairy cow performance trials using the seedling ferulate ester (sfe) corn mutant that reduces cross linking and improves IVNDFD. Digestibility of control (W23) and 2 near-isogenic sfe (M04–4 and...

This paper investigates a slug-flow expander (SFE) for conversion of high-pressure gas/vapor into kinetic energy of liquid slugs. The energy transfer from high-pressure to kinetic energy is quantified using thrust plate measurements. Non-dimensional thrust data is used to quantify performance by normalizing measured thrust by thrust for the same water flow rate at zero air flow rate. A total of...

Recently, supercritical fluid extraction (SFE) has been indicated to be utilized as part of a biorefinery, rather than as a stand-alone technology, since besides extracting added value compounds selectively it has been shown to have a positive effect on the downstream processing of biomass. To this extent, this work evaluates economically the encouraging experimental results regarding the use o...

Supercritical fluid technologies offer a propitious method for drug discovery from natural sources. Such methods require relatively short processing times, produce extracts with little or no organic co-solvent, and are able to extract bioactive molecules whilst minimising degradation. Supercritical fluid extraction (SFE) provides a range of benefits, as well as offering routes to overcome some ...
