Repeat Elements

Typically, affected surfaces are highly localized to specific regions, although if cavitation is severe and widespread, the area affected may be extensive (Fig. 12.7). On S3mimetrical components having repeated elements, the pattern of damage may repeat itself at identical locations on each element (Fig. 12.8). [Pg.277]

Northern blot analyses indicate that sequences of the four repeated elements are present on transcripts expressed in H. virescens by 2 hpp (25). Steady-state RNA levels peak at 2-6 hpp and then decline over the next 8 days. These transcripts are not as abundant as the cysteine-rich transcripts but are still major viral expression products. [Pg.86]

The introduction of EU directives on Waste Electrical and Electronic Equipment and Reduction of Hazardous Substances has highlighted the need for precise and repeatable elemental analysis of heavy metals in the plastics production process. X-ray fluorescence (XRF) spectroscopy has emerged as the most economical and effective analytical tool for achieving this. A set of certified standards, known as TOXEL, is now available to facilitate XRF analyses in PE. Calibration with TOXEL standards is simplified by the fact that XRF is a multi-element technique. Therefore a single set of the new standards can be used to calibrate several heavy elements, covering concentrations from trace level to several hundred ppm. This case study is the analysis of heavy metals in PE using an Epsilon 5 XRF spectrometer. [Pg.30]

The general result states that the number of linearly independent functions from the set UTT, S(y) i = 1,..., / is the number of standard tableaux with repeated elements that can be constructed from the labels in the H product. As a general principle, this is not so easy to prove as some of the demonstrations of linear independence we have given above. The interested reader might, however, examine the case of two-column tableaux with which we are concerned. Examining the nature of the tt, for this class of tableau, it is easy to deduce the result using ffVff. This is all that is needed, of course. The number of linearly independent functions cannot depend upon the representation. [Pg.86]

We see now why there were relatively few spin functions generated by operators from the symmetric groups. For the partition n/2 + S, n/2 — X and an Ms = X, there is only one standard tableau with repeated elements for the ordering a < (t. Thus only the itf MVM are linearly independent. All expressions of the form... [Pg.86]

Additional analysis of DNA sequences in the human genome has revealed that large blocks of human genes are filled with repeated elements, including long interspersed repetitive elements (LINEs) and short interspersed repetitive elements (SINEs). Short interspersed repetitive elements such as Alu sequences are often used as target sequences for DNA fingerprinting. [Pg.431]

Fibrous proteins, which serve mainly structural roles, have simple repeating elements of secondary structure. [Pg.146]

Fibrous proteins may achieve two-dimensional order, but they usually do not achieve three-dimensional order. Therefore, the diffraction pattern of fibrous proteins gives information about the regularly repeating elements along the long axis of the fibers but tells us very little about the orientation of amino acid side chains. [Pg.93]
