To establish the constitutive equations for carbon/PMR-15 composites and to determine the contribution of the matrix to the mechanical response, an analysis of the behavior of the PMR-15 polyimide alone has been performed under thermomechanical loading conditions corresponding to military aeroengine

A new method for the quantitative analysis of acidic opines-alanopine, strombine, tauropine, and @-alanopine-is presented. The method is based on formation of phenylthiocarbamyl (PTC) derivatives of the acidic opines aher partial purification by ion-exchange chromatography. The PTC acidic opines are
## Abstract A novel HPLC‐atmospheric pressure chemical ionization/MS (HPLC‐APCI/MS) method was developed for the rapid analysis of selected fatty and resin acids typically present in papermaking process waters. A mixture of palmitic, stearic, oleic, linolenic, and dehydroabietic acids was separated
