Spanning Simplicial Complexes of Uni-Cyclic Graphs

Algebra Colloquium 2015年第4期22卷 707-710页

作者： Imran Anwar Zahid raza Agha kashif COMSATS Institute of Information Technology Lahore Pakistan National University of Computer and Emerging Sciences Lahore Campus Pakistan National University of Computer and Emerging Sciences Lahore Campus Pakistan Department of Mathematics University of Management and Technology

In this paper, we introduce the concept of the spanning simplicial complex As（G） associated to a simple finite connected graph G. We characterize all spanning trees of the uni-cyclic graph Un,m. In particular, we give a formula for computing the Hilbert series and h-vector of the Stanley-Reisner ring k[△s（Un,m）]. Finally, we prove that the spanning simplicial complex △s（Un,m） is shifted and hence is shellable.

Parameters effect on heterogeneous photocatalysed degradation of phenolin aqueous dispersion of TiO_2

引用

Journal of Environmental Sciences 2009年第4期21卷 527-533页

作者： kashif Naeem Department of Urban and Civil Engineering Harbin Institute of Technology Shenzhen Graduate School

Photocatalytic degradation of phenol selected as model compound of organic pollutant had been investigated in aqueous titanium dioxide （TiO2） dispersion under UV irradiation. The effects of various parameters such as pH, catalyst concentration, phenol concentration, anions, metal ions, electron acceptors, and surfactants on the photocatalytic degradation of phenol were investigated. The degradation kinetics was determined by the change in phenol concentration employing UV-Vis spectrometry as a function of irradiation time. The degradation kinetics of phenol follows pseudo first-order kinetics. The results showed a significant dependence of the photocatalytic degradation of phenol on the functional parameters. The probable promising roles of the additives on the degradation process were discussed.
