In this paper, we consider the derivation of the Kadomtsev-Petviashvili (KP) equation for cold ion-acoustic wave in the long wavelength limit of the two-dimensional quantum Euler-Poisson system, under different scalings for varying directions in the Gardner-Morikawa transform. It is shown that the types of the KP equation depend on the scaled quantum parameter H > 0. The QKP-I is derived for H ...

The structures of the diastereomer diketopiperazine dipeptides cyclo(LTyr-LPhe) and cyclo-(DTyr-LPhe) are studied in gas phase using resonance-enhanced two-photon ionization, IR/UV double resonance spectroscopy quantum chemical calculation. Both diastereomers exhibit two conformations, with tyrosine ring folded over DKP phenylalanine extended outwards, or vice versa. differ only slightly by nat...

Mapping and merging of multiple ontologies to produce consistent, coherent and correct merged global ontology is an essential process to enable heterogeneous multi-vendors semantic-based systems to communicate with each other. To generate such a global ontology automatically, the individual ontologies must be free of (all types of) errors. We have observed that the present error classification ...

We study analytically the two dimensional deformed bosonic oscillator equations for charged particles (both spin 0 and 1 particles) subject to effect of a uniform magnetic field. consider presence minimal uncertainty in momentum caused by Anti-deSitter model we use Nikiforov-Uvarov method solve system. The exact energy eigenvalues corresponding wave functions are obtained both Klein-Gordon scal...

(1) Background: The aim of this study was to identify the degradation product ramipril (RAM) formed under dry air and verify its potential modes carcinogenicity. We intended check whether formation presence in final dosage forms could pose a cancer risk humans who are treated with RAM due cardiological indications. carcinogenicity compound evaluated respect two mechanisms: direct DNA-damage ind...

Bacteriolytic enzymes are promising antibacterial agents, but they can cause a typical immune response in vivo . In this study, we used targeted modification method for two endolysins, Pal and Cpl-1. We identified the key immunogenic amino acids, designed tested new, bacteriolytic variants with altered immunogenicity. One new variant of (257-259 MKS → TFG) demonstrated decreased immunogenicity ...
