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 ...
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 ...
In the 1930s - 1940s Tenerife lace was sometimes called Polka Spider Web Lace. [9] In the 1950s, a Koppo Cushion style of lace pillow was devised and sold. [10] This flexible and useful pillow style is still in use today, and can be recreated using instructions and descriptions in the patent guidelines. Sample of machine lace with Teneriffe ...
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.
A turbulent flow is a flow regime in fluid dynamics where fluid velocity varies significantly and irregularly in both position and time. [3] Furthermore, a coherent structure is defined as a turbulent flow whose vorticity expression, which is usually stochastic, contains orderly components that can be described as being instantaneously coherent over the spatial extent of the flow structure.
Macramé. Macramé is a form of textile produced using knotting (rather than weaving or knitting) techniques. The primary knots of macramé are the square (or reef knot) and forms of "hitching": various combinations of half hitches. It was long crafted by sailors, especially in elaborate or ornamental knotting forms, to cover anything from ...
The schiffli embroidery machine is a multi-needle, industrial embroidery machine. It was invented by Isaak Gröbli in 1863. [1] It was used to create various types of machine embroidery and certain types of lace. It was especially used in the textile industry of eastern Switzerland and Saxony Germany, but also in the United Kingdom and the ...
