Press Install button to start extraction.
Use Browse button to select the destination folder from the folders tree.It can be also entered manually.
If the destination folder does not exist,it will be created automatically before extraction.

3.2.Li insertion/extraction equilibrium
potential-composition isotherm of LiFe0.9 Mg0.1 PO4
Fig.4 shows the galvanostatic intermittent charge/discharge
◦
curves for LiFe0.9 Mg0.1 PO4 measured at 25 C with a succes- sive charge/discharge at a current density of 2 mA g for 2 h followed by 2.0 h of resting time (on open circuit).The reversible capacity of LiFe0.9 Mg0.1 PO4 is about 148 mA h g which is close to theoretical value of 156 mA h g of LiFe0.9 Mg0.1 PO4
[20].The equilibrium potential hysteresis of LiFe0.9 Mg0.1 PO4
between Li insertion and extraction is about 18 mV.Interestingly,the
overpotential in the two-phase region increased (from 8 to
12 mV) with the increase of Li insertion or extraction,which is attributed to the increased diffusion length according to shrink- ing core model [16].

Extraction chromatography is a form of solvent extraction where one of the liquid phases is made stationary by adsorption on a solid support.

The effect of temperature and duration of extraction on
carotenoids yield is illustrated in Fig.2.When the duration
is about 40 min,temperature becomes the critical factor for
improving carotenoids yield.The fluctuation of temperature
could lead to large difference in carotenoids yield.It
could be seen from Fig.2 that the optimal temperature and
duration for carotenoids extraction are about 30 1C and
40 min.If the duration is shorter than 40 min,the
dissolving of carotenoids would not reach equilibrium
and part of carotenoids remains in R.sphaeroides.When
the duration is longer than 40 min,the yield of carotenoids
slightly decreases.This might be due to the fact that longtime
exposure of dissolved carotenoids to oxygen,light and
microorganisms in environment leads to the increase
chances of oxidation or degradation of the dissolved
carotenoids (Gang & Zora,2001).
The effect of solvent–solid ratio and duration on
carotenoids yield is shown in Fig.3.The solvent–solid
ratio has a significant linear effect (P ¼ 0.0052) and
quadratic effect (P ¼ 0.0239) on carotenoids yield.The
yield increases when the solvent–solid ratio increases from
10 to 40 but it does not continue to increase significantly
when the ratio is higher than 40.

A decision about extraction should be based not only on the condition of the individual tooth and its supporting tissues but also upon the possible consequences of the extraction.Where periodontal breakdown is advanced,the extraction of weak teeth may create an insoluble prosthetic problem.Such developments need to be anticipated prior to extraction.The provision of removable prostheses may be necessary at this time,and care should be taken with their design,even if temporary.

The extraction of carotenoids from R.sphaeroides was
repeated four times under the optimal conditions in order
to find the suitable times to exhaust carotenoids from
R.sphaeroides.According to the data listed in Table 6,the
carotenoids yield from the first two extractions is evidently
higher than from the first extraction.The total yield does
not significantly increase when the third or the fourth
extractions are performed.If the total yield (6561 mg/g) of
carotenoids from four extractions is considered to be the
entire content of carotenoids in R.sphaeroides,then the
total yield of the first two extractions (6225 mg/g) occupied
94.89% of entire carotenoids content in R.sphaeroides,
indicating that two extractions will be enough to get a
maximal yield of carotenoids from R.sphaeroides
