Nowadays as for quantitative isolation of hemicelluloses from both hardwood and softwood,the
material should firstly be delignified,generally,with chlorine
(Timell & Jahn,1951),chlorine dioxide (Yang & Goring,1978),or
sodium chlorite,after which the left holocellulose could be treated
with various procedures.

the pace of everyday life may push us toward isolation,but there is pull,as well:a very seductive picture of standing apart as a victory,not a reteat.ever since Ralph Waldo Emerson wrote his famous essay and Henry David Thoreau set out to embodu the concept in his cabin on Walden Pond,a long series of American icons have idealized the concept of self-reliance.

Mike found that young birds raised in isolation could only make some simple sound.Mike learned that a young bird has to hear other old birds’ song during the period before it is seven seeks old.Then there is long time until the next spring before the bird begins to sing.And went it does start,it needs to practice before it finally gets the song right.
Further studies have proved that young birds do indeed need musical education.After several of the young birds raised in isolation were put together for about ten months,they learned from one another and finally could sing.The songs they sang,however,were quite different from the wild birds’.On the other hand,the young birds caught after their time was spent listening to the wild birds’ songs,knew how to sing.

Because of the relative isolation of the island,the people of Jeju have developed a culture and language that are distinct from those of mainland Korea.Jeju is home to thousands of local legends.Perhaps the most distinct cultural artifact is the ubiquitous dol hareubang ("stone grandfather") carved from a block of basalt.Another distinct aspect of Jeju is the matriarchal family structure,found especially in Udo and Mara,but also present in the rest of the province.The best-known example of this is found among the haenyeo ("sea women"),who were often the heads of families,because they controlled the income.

4.19 Isolation Resistance.隔离电阻
4.19.4 Procedure.
Note:For sealed connector pairs,complete all measurements
in this test procedure within one hour after
any previous environmental test.
Note:For unsealed connector pairs,test samples
shall rest at ambient temperature and humidity for
3 h min.prior to measuring isolation resistance after
any previous environmental test.
1 Mate connector pairs.
2 Wrap metal foil around the exterior of the connector
without contacting any terminals or wires.
3 Remove a minimal amount of insulation from the
ends of the wires.
4 Separate wires under test with sufficient distance
as to have no influence on isolation resistance
between any two wire pairs.
5 Measure the isolation resistance by applying
500 VDC between all adjacent pairs of terminals.
6 Record the resistance after 15 s of stabilized readings.
7 Attach all the terminated wire leads to the positive
lead of a Mega-Ohmmeter.Attach the negative
lead of the Mega-Ohmmeter to the metal foil.
8 Measure the isolation resistance by applying
500 VDC between the terminals and the metal foil.
9 Record the resistance after 15 s of stabilized readings.
4.19.5 Acceptance Criteria.All measured isolation
resistances shall be > 100 M .

Thanks to life with you!I'm not fight in isolation may perhaps!I have been accustomed to you!Have complete trust in you!But unfortunately we can't get is forever!I was destined to be a passer-by!Please forgive my cowardly and cruel!How many nights around the anti side!How many times the inner struggle!But I still think foolish not to let anyone hurt way!In the end only sorry!Only for you deeply indebted!To accept my deep feeling of guilt when!Please accept me to your deep sincere wishes - happy forever!求全文翻译

isolation
the third and last method for water ballast management is isolate the water on board ,or in other words to prevent that water from the location of departure in comes in contact with water at the location of arrival.there are three solutions.
1 to deliver the water onshore where it can be treated separately without affecting the operational discharging and loading procedures.water can than be processed by a land-based reception facility.this solution requires large infrastructure at every port ,ensuring sufficient capacity for all ships .presently these facilities are not (yet)
available in ports .
2 to return the water to its origin .this can only be done by ships sailing on a fixed route and with sufficient deadweight to carry this amount of ballast water during the loaded voyage.for most ships this means that paying capacity is reduced to allow for taking sufficient ballast water
3 to keep the water ballast outside the vessel.this means that vessel design is such that no ,or only very limited ballast water is required to guarantee both fully laden and when empty
