Silk Engineering: Silk Engineering was a British motorcycle manufacturer established by George Silk and Maurice Patey and based at Darley Abbey, Derbyshire. They produced Silk 700S two-stroke motorcycles until 1979.Fibroin: Fibroin is an insoluble protein present in silk created by spiders, the larvae of Bombyx mori, other moth genera such as Antheraea, Cricula, Samia and Gonometa, and numerous other insects. Silk in its raw state consists of two main proteins, sericin and fibroin, with a glue-like layer of sericin coating two singular filaments of fibroin called brins.Huwentoxin: Huwentoxins (HWTX) are a group of neurotoxic peptides found in the venom of the Chinese bird spider Haplopelma huwena. While structural similarity can be found among several of these toxins, HWTX as a group possess high functional diversity.Cynthia (Gaba girl): Cynthia was a plaster mannequin of the 1930s created by Lester Gaba.Addis Black Widow: Addis Black Widow is a Swedish band. Their songs include "Innocent", "Wait in Summer", and "Goes Around Comes Around", which reached #2 on the Swedish Tracks Chart in 2001.Bombardier Challenger 300: The Bombardier BD-100 Challenger 300 is a super-mid-sized jet capable of traversing transcontinental distances. It is not developmentally related to the similarly named Challenger 600 series, or the 600-derived Challenger 800 series.Surface modification of biomaterials with proteins: Biomaterials are materials that are used in contact with biological systems. Biocompatibility and applicability of surface modification with current uses of metallic, polymeric and ceramic biomaterials allow alteration of properties to enhance performance in a biological environment while retaining bulk properties of the desired device.Thermogravimetry: Thermogravimetry (also known by the acronym "TG"; alternative spellings include thermo-gravimetry and thermogravimmetry) is a branch of physical chemistry, materials research, and thermal analysis. It is based on continuous recording of mass changes of a sample of material, as a function of a combination of temperature with time, and additionally of pressure and gas composition.Ductility: In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire. Malleability, a similar property, is a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling.
