Suppose $n$ is a fixed positive integer. We introduce the relative n-th non-commuting graph $Gamma^{n} _{H,G}$, associated to the non-abelian subgroup $H$ of group $G$. The vertex set is $Gsetminus C^n_{H,G}$ in which $C^n_{H,G} = {xin G : [x,y^{n}]=1 mbox{~and~} [x^{n},y]=1mbox{~for~all~} yin H}$. Moreover, ${x,y}$ is an edge if $x$ or $y$ belong to $H$ and $xy^{n}eq y^{n}x$ or $x...

This paper proposes an approach to constructing a 3-D paper-m ad e ob ject from a crease pattern, a set of line segm ents (creases) on a sheet of paper w hich is usually prod uced w hen a paper-m ad e ob ject such as origam i is unfold ed . F irst, a coord inate transform ation m ethod from 2 -D crease patterns to 3-D space is proposed . S ince faces (form ed b y the creases) m ore than tw o ar...
In this paper, we study some properties of analytic extension of a $n$th roots of $M$-hyponormal operator. We show that every analytic extension of a $n$th roots of $M$-hyponormal operator is subscalar of order $2k+2n$. As a consequence, we get that if the spectrum of such operator $T$ has a nonempty interior in $mathbb{C}$, then $T$ has a nontrivial invariant subspace. Finally, w...
This review focuses on the application of Th as a proxy for the flux of particulate organic carbon (POC) from the surface ocean. The use of this Th flux approach requires determination of both the Th activity distribution (used to calculate Th fluxes), and an estimate of the C/Th ratio on sinking particles to empirically derive C fluxes. Observations have shown that in general C/Th decreases wi...
Immunization of BALB/c mice with nuclease leads to the production of anti-nuclease antibodies bearing a set of cross-reactive idiotypes (Id) distinct from those produced by B10.D2 mice after similar immunization. In both strains, such immunization with nuclease also leads to the production of splenic T helper cells (TH), which provide nuclease-specific help in an in vitro plaque-forming cell re...
Cholera is an acute infectious disease with high mortality if left untreated. Historically, between the 19(th) and 20(th) centuries seven great pandemics of cholera occurred and worldwide, thousands of people died. Based on an old theory, cholera was considered an air-born disease and the emergence of its outbreaks were attributed to bad weather or miasma. However later in the 18(th) century, B...
The first thorium poly-carbene complexes [(Ph(2)P=S)(2)C](2)Th(DME) (2) and [{[(Ph(2)P=S)(2)C](3)Th}Li(2)(DME)](n) (3) have been prepared and structurally characterized. DFT calculations reveal that the Th=C bond is polarized toward the nucleophilic carbene carbon atom, which is further verified by the experimental observation that the Th=C bond shows a nucleophilic behavior with Ph(2)CO.
