The structure of the repeating unit of PPP Space-filling model of a short section of PPP. Poly(p-phenylene) (PPP) is made of repeating p-phenylene units, which act as the precursor to a conducting polymer of the rigid-rod polymer family. The synthesis of PPP has proven challenging, but has been accomplished through excess polycondensation with ...
Description: A flowchart that shows the phases of the Point-to-Point Protocol.This file was created in Inkscape because an SVG I drew initially with MS Visio 2007 was rejected as corrupt when I tried to upload it to the Wikimedia Commons, and the one I drew in OpenOffice.org rendered improperly in Firefox.
A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps.The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains, leading to the release of sewer gas into the environment.

It performs a fast, gapless alignment to test the complementarity of the primers to the target sequences. Probable PCR products can be found for linear and circular templates using standard or inverse PCR as well as for multiplex PCR. Dicey [15] is free software that outputs in-silico PCR products from primer sets provided in a FASTA file.
Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
