Boucle yarn is a specialized type of yarn that is usually made of three plies. Among the three plies used to create this yarn, one thread is usually looser than the others. The looser thread causes the yarn to have a rough feeling and a bulky look. This also makes it more likely to unravel than some other types of yarn.
Cold Metal Transfer - CMT - A Revolution in Mechanized Root Pass Pipeline Welding. CMT is the abbreviation for Cold Metal Transfer. The CMT process was originally intended for use as a method for joining thin gauged materials in the automotive industry. In 2006 CRC-Evans initiated an investigation to understand if this technology was suitable for root pass deposition on pipeline girth welds.
Transduction is the transfer of genetic information from a donor to a recipient by way of a bacteriophage. The phage coat protects the DNA in the environment so that transduction, unlike transformation, is not affected by nucleases in the environment.ene transfer in bacteria is unidirectional from a donor cell to a recipient cell and the donor usually gives only a small part of its DNA to the recipient. Thus, complete zygotes are not formed; rather, partial zygotes (merozygotes) are formed.
