21. Also, command line compilers and linkers often have options that are not available from menu-based systems. 22. System software includes software categories such as operating systems, utility software, device drivers, compilers, and linkers . 23. Small porous beads are treated with functional units ('linkers ') on which peptide chains can be built. 24. The S3-S4 linkers of Cav1.2 determine the gating phenotype and modulated gating kinetics of the channel. 25. "' Emile Emanuel Anthony Linkers "'( born 25 September 1990 ) is a football player. 26. One of these cross-linkers is glutaraldehyde, a substance commonly used in everything from food processing to medical applications. 27. Factors that decrease the binding are steric hindrance on the amino group and linkers that are saturated / unsaturated carbon chains. 28. Another structure was used for this complexation type, two disaccharidyl units connected by urea linkers to a diazacrown ether organizing platform. 29. The total absorbency and swelling capacity are controlled by the type and degree of cross-linkers used to make the gel. 30. Zeolites are limited by the fixed tetrahedral coordination of the Si / Al connecting points and the two-coordinated oxide linkers .
