Harrington jacket

A Harrington jacket is a type of minute, lightweight jacket, made of cotton, polyester, wool or suede — usually with a tartan or check-patterned lining.

The initial Harrington-style jackets were made by British clothing company, Barracuda, in the 1930s; the company is still making the same model, the G9. This style of jacket got the nickname Harrington because it was worn by the personality Rodney Harrington in the 1960s television program Peyton Place; John Simmons, who opened 'The Ivy Shop', Richmond, London, claims to have coined this explanation.

Protein

Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by a gene and encoded in the genetic code. Although this genetic code specifies 20 "standard" amino acids, the residues in a protein are often chemically altered in post-translational modification: either before the protein can function in the cell, or as part of control mechanisms. Proteins can also work together to achieve a particular function, and they often associate to form stable complexes.

Digital image

A digital image is an illustration of a two-dimensional image as a finite set of digital values, called picture elements or pixels. The digital image contains a fixed number of rows and columns of pixels. Pixels are the smallest individual element in an image, share quantized values that represent the brightness of a given color at any specific point.

Pedestrian crossings

Pedestrians must often traverse from one side of a road to the other, and in doing so may come into the way of vehicles traveling on the road. In many places pedestrians are completely left to look after themselves, that is, they must observe the road and cross when they can see that no traffic will threaten them. Busier cities usually provide pedestrian crossings, which are strips of the road where pedestrians are expected to traverse.
