This potential ambiguity will be minimized by two-step PPD testing, in which a second PPD test is made one to three weeks after the first if the first test is negative. Those who are positive because of boosting will thus be identified. Then, those who convert with subsequent testing can ...
aβ-glucosidase localized to the chloroplast, was discovered to specifically hydrolyze PPD ginsenosides in PNLs by selectively removing one outer glucose residue at the C-3 site. Due to spatial separation betweenβ-glucosidase and its substrates in cells, ginsenoside...
Taken together, we propose a two-step evolution model for fruit size enlargement in apple to characterize its unique evolution process (Fig.4c). Unlike modern maize and tomato whose domestication process started with ancestral species bearing very small seeds or fruits4,5, apple domestication was i...

There are two key issues which need to be raised when dealing with the concept of homework. Firstly, there is the question of home. Often homework is not done at home at all, but at a friend's house, on the street, on the bus on the way to class or sitting o...
OUTPUT PRE-EMPHASIS The SN75LVCP422 provides single step pre-emphasis from 0 dB to 2.5 dB at each of its differential outputs. Pre-emphasis is controlled independently for each channel and is set by the control pins D0 and D1 as shown in Table 1. The pre-emphasis duration is 0.5 UI ...
