Nucleon transfer calculations using HIPSE model

The HIPSE (heavy-ion phase-space exploration) model, by Lacroix et al., has been used to examine nucleon transfer during the interaction of the projectile and target [1]. The results of the HIPSE model were compared to experimental data obtained on the FAUST array (Forward Array Using Silicon Technology) for F + Ag, F + Au, Na + Au, and Ne + Au at 32 MeV/u [2]. The apparent mass change of the p...

Supercritical Fluid Extraction of β-Carotene from Crude Palm Oil Using CO2 in a Bubbler Extractor: Mass Transfer Study

In this study, the diffusivity and volumetric mass transfer coefficients for the extraction of β-carotene from crude palm oil using CO2 solvent in supercritical fluid were determined in the pressure range of 7.5-17.5 MPa and temperature range of 80-120 ºC. For this purpose, a statistical method was applied in order to minimize the number of experiments required. The volumetric ma...

Bridging the gap between laboratory measurements and field estimations of silicate weathering using simple calculations

Weathering rates of silicate minerals observed in the laboratory are in general up to five orders of magnitude higher than those inferred from field studies. Simple calculations show that even if the field conditions were fully simulated in standard laboratory experiments, it would be impossible to measure the slow rates of mineral dissolution that are observed in the field. As it is not possib...

Cygnus X - 2 , super - Eddington mass transfer

We consider the unusual evolutionary state of the secondary star in Cygnus X-2. Spectroscopic data give a low mass (M 2 ' 0:5 ? 0:7M) and yet a large radius (R 2 ' 7R) and high luminosity (L 2 ' 150L). We show that this star closely resembles a remnant of early massive Case B evolution, during which the neutron star ejected most of the 3M transferred from the donor (initial mass M 2i 3:6M) on i...

Postmortem Internal Gas Reservoir Monitoring Using GCGC-HRTOF-MS

Forensic investigations often require postmortem examination of a body. However, the collection of evidence during autopsy is often destructive, meaning that the body can no longer be examined in its original state. In order to obtain an internal image of the body, whole body postmortem computed tomography (PMCT) has proven to be a valuable non-destructive tool and is currently used in medicole...
