Others pivot from both bottom (like a hopper) and the side (like a casement). Also called Dual Action. Double-Hung Windows: Include offset upper and lower sashes, which can both move up and down in the frame. A window having two vertically sliding sash, each closing a different part of the window.
Reaction of sugar oxazolines with primary amines. In order to scrutinize the reaction pathway and structure of the reaction product, we started with a simple sugar oxazoline and a primary amine, carrying no other functional groups.
Chemical reactivity: comparison of alkylanilines with multi-ring carcinogenic amines. A paradigmatic model for aromatic amine genotoxicity has evolved over the last forty years from the seminal work of James and Elizabeth Miller and their coworkers that is described in detail in several later publications (5, 26, 27).ertainly, DNA adducts of the same basic structure as formed by multi-ring amines can be synthesized via nitrenium ions. Aniline, the simplest aromatic amine, forms the dGâC8 adduct when it is present in the reaction in the activated form, N-acetoxyaniline (28).
