The basic idea behind this extraction procedure was to homogenize a tissue sample (Folch and Lees 1951; Sperry and Brand 1955) in a mixture of chloroform and methanol in volumetric ratios of 2:1. The initial extraction step results in non-extractable residue and one liquid phase containing a wide range of small biomolecules.
The extraction ratio of an organ of elimination (e.g. the liver or the kidneys) can be viewed as the measure of the organ's relative efficiency in eliminating the drug from the systemic circulation over a single pass through the organ. The extraction ratio may range from 0 to 1. An extraction ration close to 0 indicates that most of the drug ...
ratio can affect both the thermodynamics and kinetics involved with extraction or leaching. Thermodynamically, the greater the surface area to solution volume ratio, the greater …

Extraction Ratio. The extraction ratio is thus defined as the ratio of total drug clearance from an organ to the blood flow supplying that organ. From: Pharmacology, 2009
Les coûts en capital varient essentiellement en fonction du potentiel de la mine, du rythme d'extraction, de la teneur, de la technologie employée et de la géologie. Les coûts en capital sont financés par emprunt à hauteur de 90% ou limités par le ratio de souscapitalisation défini par la législation.

Ultrasound assisted extraction (UAE) is one of the preferred green extraction techniques widely used for the extraction of bioactive compounds from plant materials. It has attracted much attention and many studies have been done to understand its mechanism, effects and efficiency.
To find your perfect ratio, start with a basic recipe using a scale to measure everything accurately; then adjust accordingly. Don't be afraid to try different ratios and modify the variables either, just make sure to only change 1 variable at a time.. For me, I found the sweet spot for longer shots at a lower dose of 1:4.5, while I pull my espresso …
For example, at 60°C and solvent to sappanwood ratio 8:1, the process yielded 4.0% extract for 15 minutes. Compared to the literature with conventional extraction without ultrasound, this achievement was twofold. Lowering solvent to sappanwood ratio reduced the extract yield, but it will ease in product separation.
Therefore, the compromise between higher energy extraction efficiency and lower costs of manufacturing and installation suggests that an aspect ratio around AR = 4 is the most appropriate choice ...
Department of Health, 2011) states: "Whilst a high native extraction ratio is generally reflective of a targeted extraction procedure (i.e., specific components or component classes are selected for), there are instances where a high extraction ratio may simply reflect a partial extraction procedure." For example, if a plant biomass with a ...
En 2015, le ministre en charge des mines a lancé des travaux pour définir le concept de la mine en France : une mine construite comme un projet de territoire qui réduit autant que possible les ...
The feature extraction method successfully extracted the characteristic peaks of melamine despite the noise from employing a low excitation laser (10 mW).. Using the method proposed in this paper, the Raman signal of biological samples such as rice leaves were extracted from the raw spectrum, and information on the spectral peak position, …

Le décapage : C'est un terrassement de très faible profondeur (environ de 25cm) et de grande surface. Le décapage est l'opération de terrassement qui vise à ôter la couche la plus superficielle de terre. Cette couche se compose généralement de végétaux ainsi que des déchets organiques rendrant instable le futur édifice.
The shift-and-ratio method has been considered as one of the most accurate and consistent techniques for extracting the effective channel-length of the MOS transistor. This method assumes the effective mobility of a long channel and a short channel transistor to be equal. Scaling down the MOS transistor urges the need of including halo (or pocket) …

As the plasma sample-to-solvent ratio decreased from 1:4, 1:10, 1:20, and 1:100 (v/v), many of the Cer, LPC, PC, and PE lipid species increased in peak area for the Bligh-Dyer, Folch, and Matyash methods as shown in Figure 1. Anova comparisons across sample-to-solvent ratios for each lipid extraction method can be found in Table S2.
