The present paper provides a compound having high acid corrosion protection properties based on amine-containing compounds. The amine used is the condensation of individual polyethylenepolyamines (PEPA), in particular diethylenetriamine (DETA) and isobutyric acid, followed by alkylation of the resulting compound by means of alkenylsuccinic acid. The structure of obtained amidoimide has been confirmed by IR spectrum. The physicochemical parameters of the compound were studied; amidoimide tests were carried out to assess the inhibitory ability by gravimetric and electrochemical methods. [ABSTRACT FROM AUTHOR]

Hexanitrohexaazaisowurtzitane is an azostructural compound known as CL-20. We performed a series of experiments with CL-20 synthesized in Russia to evaluate the possibility to use it in pressed high explosive compositions. We used it in thermoplastic compositions both with an inert binder and energetic binder. The compositions were conventionally named CL-20И and CL-20A. It was determined that the thermoplastic compositions had the most high detonation parameters and a level of sensitivity to mechanical effects acceptable to allow their processing. Their detonation characteristics were compared with that of some known foreign compositions based on CL-20. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]

In some SUSY extensions of the Standard Model superpartner of t-quark may form bound states. We estimate potentials of future linear collider in search for these new narrow strong resonances, considering the e[sup +]e[sup -] and γγ options. [ABSTRACT FROM AUTHOR]

We present a method for symbolic evaluation of Feynman amplitudes. We construct special polarization basis for spinor particles which produces compact expressions for tensor products of basis spinors. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]

CompHEP, as a partonic event generator, and PYTHIA, as a generator of final states of detectable objects, are interfaced. Thus, integrated tool is proposed for simulation of (almost) arbitrary collision processes at the level of detectable particles. Exact (multiparticle) matrix elements, convolution with structure functions, decays, partons hadronization and (optionally) parton shower evolution are basic stages of calculations. The PEVLIB library of event generators for LHC processes is described. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]
