Six types of weight changes that occur when food is cooked by different methods are described. For five of these types, true retentions of nutrients (defined as calculations based on nutrient content of known weights of food before and after cooking) were compared with apparent retentions (defined as calculations based on nutrient content of moisture-free raw and cooked foods). Comparisons incl...

conclusions it can be concluded that the devisable memory-enhancing effects of red lentil (lens culinaris) are due to the antioxidant activity of its flavonoid, tannins, and terpenoids. background since ancient times, people have believed that certain foods or plants can affect learning and memory potency in humans. the consumption of food and beverages rich in flavonoid compounds has been prop...

BACKGROUND Although specialist physicians comprise nearly half of the physician workforce in Newfoundland and Labrador (NL), relatively little is known about their retention patterns. We compared 2 cohorts of physicians who were initially licensed to practise in NL between 1993 and 1997 and between 2000 and 2004, to examine whether retention had changed over time. Additionally, we examined the ...

As columns age and differ between systems, retention times for comprehensive two-dimensional gas chromatography (GCxGC) may vary between runs. To properly analyze GCxGC chromatograms, it often is desirable to align the retention times of chromatographic features, such as analyte peaks, between chromatograms. Previous work by the authors has shown that global, low-degree polynomial transformatio...

We develop the Kernel Multitask Latent Analysis (KMLA) method for modeling many-to-many relationships between inputs and responses, and show how it can be applied to inductive transfer problems in bioseparations. KMLA performs dimensionality reduction targeted towards a multitask loss function much like Kernel Partial Least Squares (KPLS). KPLS is limited to least squares multiple regression wh...

We developed a n-hexane/surfactant-containing water solvent system in counter-current chromatography (CCC) in order to separate hydrophobic compounds. By using the upper phase as the mobile phase, we have separated steroid samples. Retention times of steroids progesterone and delta4-androstene-3,17-dione increased slightly by increasing the concentration below the critical micellar concentratio...

The chinchilla (Chinchilla laniger) is a herbivorous hystricomorph South American rodent for which no mean digesta retention times have been reported so far. Six animals (mean body mass ± standard deviation: 513 ± 99 g) on a diet of grass hay and lucerne-based pellets were given a pulse dose of a solute (cobalt-EDTA) and a particle (chromium-mordanted fibre, <2 mm) marker with subsequent freque...

The demand for highly scalable, low-power devices for data storage and logic operations is strongly stimulating research into resistive switching as a novel concept for future non-volatile memory devices. To meet technological requirements, it is imperative to have a set of material design rules based on fundamental material physics, but deriving such rules is proving challenging. Here, we eluc...
