Hairpin lace is a lace-making technique that uses a crochet hook and two parallel metal rods held at the top and the bottom by removable bars. Historically, a metal U-shaped eponymous hairpin was used. Hairpin lace is formed by wrapping yarn around the prongs of the hairpin lace loom to form loops, which are held together by a row of crochet ...
Stem-loop. Stem-loops are nucleic acid secondary structural elements which form via intramolecular base pairing in single-stranded DNA or RNA. They are also referred to as hairpins or hairpin loops. A stem-loop occurs when two regions of the same nucleic acid strand, usually complementary in nucleotide sequence, base-pair to form a double helix ...
Hairpin technology is a winding technology for stators in electric motors and generators and is also used for traction applications in electric vehicles. In contrast to conventional winding technologies , the hairpin technology is based on solid, flat copper bars which are inserted into the stator stack.
Intrinsic, or rho-independent termination, is a process to signal the end of transcription and release the newly constructed RNA molecule. In bacteria such as E. coli, transcription is terminated either by a rho-dependent process or rho-independent process. In the Rho-dependent process, the rho-protein locates and binds the signal sequence in ...
A beta hairpin is a common supersecondary motif composed of two anti-parallel beta strands connected by a loop. The structure resembles a hairpin and is often found in globular proteins. The loop between the beta strands can range anywhere from 2 to 16 residues. However, most loops contain less than seven residues. [2]
Beta hairpin. The beta hairpin (sometimes also called beta-ribbon or beta-beta unit) is a simple protein structural motif involving two beta strands that look like a hairpin. The motif consists of two strands that are adjacent in primary structure, oriented in an antiparallel direction (the N-terminus of one sheet is adjacent to the C-terminus ...
Tatting is a technique for handcrafting a particularly durable lace from a series of knots and loops. [1] Tatting can be used to make lace edging as well as doilies, collars, accessories such as earrings, necklaces, waist beads, and other decorative pieces. The lace is formed by a pattern of rings and chains formed from a series of cow hitch or ...
Lace knitting is a style of knitting characterized by stable "holes" in the fabric arranged with consideration of aesthetic value. Lace is sometimes considered the pinnacle of knitting, because of its complexity and because woven fabrics cannot easily be made to have holes. Famous examples include the Orenburg shawl and the wedding ring shawl ...
