A clean concentrate collection pan was placed under the overflow lip of the cell.
To recover the concentrated and desalted sample, the filter was placed upside down in a clean micro centrifuge tube and centrifuged for 2 minutes at 1000xg.
For the first set of experiment, freshly prepared samples of low (10 mass %) concentrated suspensions were placed between two electrodes by partially immersing the electroacoustic (SP-80 probe) device into the liquid dispersion inside of the sample holder (Teflon vesel, SP-80 Cell) of the ESA-8000 device [see Fig. 3a], and allowed to equilibrate at 23 °C before ESA measurements [12].
Concentrated aliquots were placed into cryovials and stored at −80°C for further analysis.
They are matching more carefully the shows and the products being placed, and concentrating placements in certain programming genres like reality, sports and game shows, where they may raise fewer hackles than if plopped into situation comedies or other scripted series.
The PaP1 particles were concentrated using PEG8000 (these particles were placed in an ice bath for 1 h and centrifuged at 12,000 × g for 10 min; the precipitate was then collected) and further purified using a CsCl gradient ultracentrifuge in accordance with previously reported methods [ 21, 22].
The trypsin-digested peptides, concentrated by Ziptip C18 (Millipore), were placed on the anchor chip of a MALDI-TOF mass spectrometer (Ultrafrex, Bruker Daltonics, Bremen, Germany) together with 100 fmol of a bradykinin fragment (m/z of 757) (Sigma, St Louis, MO, USA) as an internal control and 0.3 μg of 4-hydroxy-α-cinnamic acid matrix.
With so many phenomena, across so many fields of research, showing concentration,2 perhaps rather than ask, how concentrated is crime at places, we should ask, how concentrated is crime at places compared to other phenomena?
In IUI motile spermatozoa are concentrated and placed directly into the uterine cavity, in closer proximity to the released oocyt than is the case after vaginal intercourse.
The goal of this system was to promote and ensure equality among residents of different regions of the country, with tax revenues raised in Tokyo and Osaka and other wealthy areas where industry is concentrated are redistributed to poorer places.
