Intelligence specialists from Korea and the United States have yet to find any unambiguous evidence of preparations for nuclear testing.
The only unambiguous exception is the preparation of several C2F5 derivatives of C60 by nucleophilic substitution (T1#110).
This strategy was previously used to successfully assign a number of residues in CHO-cell derived TGF-β1, but has the disadvantage that unambiguous assignment of each amide requires preparation of a separate sample.
The imidazoquinoline and imidazoquinoxaline food mutagens found in cooked meat are being synthesized by unambiguous methods that allow for the preparation of sufficient quantities of material for biological studies.
"Universities should provide clear and unambiguous guidance without favour on the best preparations for their courses and then allow merit to dictate entry," he added.
The analysis time was 5−7 min. In addition to meeting the criteria above, namely, fast, direct, and unambiguous determination of Hb variants with no sample preparation, the method allows for repeated analysis of the dried blood spots with no loss of mass spectral response over a prolonged time period (months).
It became obvious that clear and unambiguous phrasing of answers is of paramount importance in the preparation of LMQs.
The method allows rapid, unambiguous determination of Hb variants HbS, HbC, and HbD, with no sample preparation and minimal sample handling.
The purpose of any tissue preparation protocol for LCM is to obtain tissue sections allowing for unambiguous identification and successful capture of the cells of interest, while maintaining RNA integrity.
As DENVs share antigenic similarities with other flaviviruses and tend to co-circulate with some of them in many endemic areas, the unambiguous detection of anti-DENV antibodies using currently available commercial kits, which use mixtures of inactivated virus preparations or recombinant envelope proteins for antibody detection, is often not possible [ 2].
