The study of nano- and submicron Brownian particle-laden turbulent flow has wide industrial applicability and hence has received much attention. The purpose of the present paper is to provide and review some researches in this field. The topics are related to the universality, particularity, complexity and importance of nano- and submicron Brownian particle-laden turbulent flow, the models of particle general dynamical equation, the collision behavior of particles. Finally, several open research issues are identified.

Let H1,H2 be subgroups of a finite group G. Assume that G = umlH2yiH1 = n Uj=1 HlgiH1 and that y1=1,g1= 1. Let Di be the set consisting of right cosets of H~ contained in H2yiH1 and let dj （j --- 1,..., n） be the set consisting of right cosets contained in HlgjH1. We define the n x m matrix Mz （z = 1,..., m） whose columns and rows are indexed by Di and dj respectively and the （dk, Dz） entry is ｜Dzgk N Dl]. Let M =（M1 , Mm）. Assume that 1GH1 and 1H2G are semisimple permutation modules of a finite group G. In this paper, by using the matrix M, we give some sufficient and necessary conditions such that 1~1 is isomorphic to a submodule of 1H2G. As an application, we prove Foulkes＇ conjecture in special cases.

The ring expansion procedures over various forming velocities are calculated with ANSYS software in order to show the effect of forming velocity on ductility of rate insensitive materials. Ring expansion procedures are simplified to one-dimensional tension by constraining the radial deformation, with element birth and death method, fracture problem of circular ring are considered. The calculated results show that for insensitive materials of 1060 aluminum and 3A21 aluminum alloy, fracture strain increases corresponding to the increase of forming velocity. This trend agrees well with experimental results, and indicates inertia is the key factor to affect ductility; With element birth and death methods, fracture problems can be solved effectively. Experimental studies on formability of tubular workpieces are also conducted, experimental results show that the formability of 1060 aluminum and 3A21 aluminum alloy under electromagnetic forming is higher than that under quasistatic forming, according to the characteristics of electromagnetic forming, the forming limit diasrams of the two materials tube are also built respectively, this is very important to promote the development of electromagnetic forming and guide the engineering practices.

Glycosylation produces a diverse and abundant repertoire of glycans that help protein folding and cellular secretion[1].Glycoproteins often sprout sialic acid(alias N-acetyl neuraminic acid,abbreviated as Neu5Ac)at the termini of their N-and O-glycans in a process called sialylation[2].Alterations to the normal function of the glycosylation machinery,including increased branching of N-linked glycans and sialylation,are major hallmarks of cancer ***,increased sialylation on the
