• Global attractors of nonlocal reaction diffusion equations with exponential nonlinearitiesGlobal attractors of nonlocal reaction diffusion equations with exponential nonlinearities

    Abstract: In this paper, we investigate the existence, uniqueness, and continuity of weak solutions with respect to initial values for a nonlinear parabolic equation of reactiondiffusion nonlocal type by an application of the Faedo-Galerkin approximation and AubinLions- Simon compactness results. The nonlocal quantity appears in the diffusion coef...

  • Study boltzman distribution function for ideal gas systemStudy boltzman distribution function for ideal gas system

    Abstract: Consider an ideal gas system consisting of a large number of particles. The nature of the macroscopic system could not be described in detail. It could only be described in terms of averages, i.e. only the mean values of the thermodynamic quantities characteristic of the medium of the macro system. The average values of the thermodynam...

  • Determined conditions of laser field on acoustic phonon increasing in semiconductor blockDetermined conditions of laser field on acoustic phonon increasing in semiconductor block

    1. Introduction Phonon amplification by absorption of laser field energy is a subject extensively investigated in different structures [1,2,3,4,8]. The main results of these papers are that by absorption of laser field energy, the interaction of the laser field with electron can lead to the excitation of higher harmonics and the amplification o...

  • Some main occurrences of crossed modulesSome main occurrences of crossed modules

    1. Introduction Crossed modules (over groups) were invented almost 70 years ago by J. H. C. Whitehead in his work on combinatorial homotopy theory [10]. Whitehead's ideas on crossed modules and their applications were developed and explained in the book by R. Brown, P. J. Higgins, R. Sivera [1]. Some generalisations of the idea of crossed modul...

  • Semi-synthesis of some heterocyclic triterpene derivatives on the basis of allobetulinSemi-synthesis of some heterocyclic triterpene derivatives on the basis of allobetulin

    Abstract: Semi-synthesized products derived from natural compounds currently play an important role in the research and finding new substances. Allobetulin, obtained through a process of transformation from betulin, is compound extracted from the birch trees, could be used as the starting material for some transformation reactions. Some new deri...

  • On nearly prime submodulesOn nearly prime submodules

    1. Introduction and preliminaries In [10], weakly prime ideals in a commutative ring with non-zero identity have been studied. Many authors have studied the notion of weakly prime ideals in module theory. In particular, many properties of weakly prime submodules have been introduced by M. Behboodi and H. Koohi in [11]. In this paper, we introdu...

    ABSTRACT There has not been many documentation and architectural analyses of historical building in Sarawak, particularly in Sibu. Masjid Al Qadim is one of the oldest mosques in Sarawak and the only one gazetted as Historical Buildings under the Sarawak Cultural Heritage Ordinance 1993. Lack of interest in historical building results in little ...
