The carbon content of monoterpenes has been taken as reference for the classification of terpenoids, like sesqui-, di-, sester-, and tri-, as they are formed by iterative condensation of C5-isoprene units up to C25. Two C15 units condense to form C30 compounds (cf. Fig. 5.15).

C15 Disease-modifying antirheumatic drugs
2011RHEUMATOID ARTHRITIS (RA) is the most common inflammatory rheumatic disease, with a prevalence of about 1%. Targeting the synovial membrane, cartilage and bone, untreated RA leads to joint destruction, disability and increased mortality. Although the total incidence of this disease is low, the level of ill health and economic burden is significant with

Alloy Digest
Abstract 1015, C15E, and C15R are wrought low-carbon (carbon equals 0.12 to 0.18 percent) non-alloy steels that are used in the as rolled, annealed, normalized, or cold worked condition. They are widely used for lightly and moderately stressed parts that require higher strength levels than can be achieved by the lower carbon grades, and ...

Synthesis of the C15-C35 Segment of Chivosazole A
Synlett, 2007The synthesis of the C15-C35 segment of chivosazole A is reported using a convergent approach that incorporates an E-selective Wittig olefination for joining both subunits of this fragment.

Synthesis of the C8-C15 Segment of (+)-Discodermolide
Chemistry Letters, 1997Abstract Succeeding to the preceding paper, stereoselective synthesis of the C8-C15 segment of (+)-discodermolide (1), the marine natural product having the potent immunosuppressive activity, is described in which the contiguous asymmetric centers at C11 and C12 positions were stereospecifically constructed via the methylation of an ...

Transference of wheel loading (C15)
1982A vehicle under retardation due to braking, Fig. 15.1, has the frictional forces (FF and FR) introduced between tyres and road surface, and at the same time an equal but opposite inertia force (FT) acts at the point of centre of gravity creating a moment FTh N m which transfers weight (w) or vertical loading from rear to front wheels.

C15: The linux components for control systems
IFAC Proceedings Volumes, 2004Abstract Today many vendors covering the process control automation area offer a variety of products using a Linux operating system. These controllers, communication and visualisation resources meets customer requirements for easy and relatively low-cost integration with information systems for enterprise management, as they contain standardized ...

C15-F15 charge symmetry and the C14(n,γ)C15 reaction Puzzle
2006The low-energy reaction C14(n,γ)C15 provides a rare opportunity to test indirect methods for the determination of neutron capture cross sections by radioactive isotopes versus direct measurements. It is also important for various astrophysical scenarios.
