Studies of the structure of atoms and ions (ultracold to relativistic included) as well as their twobody interactions with photons, electrons and other particles require accurate methods for the description of such objects. In order to obtain accurate values of atomic quantities it is necessary to account for relativistic and correlation effects. Relativistic effects may be taken into account a...

this paper, based on two dialects of kurdish, studies the -g{r suffix of farsi morphologically and semantically. in the sorani (so:rani) dialect of kurdish this suffix is -k{r. in hawrami (h{wrami) dialect of kurdish the present verbal stem of (k{rdaj) (to do) is -k{r and in sorani it is -k{. sorani has a suffix called -{r similar to english -er that produces nouns with mainly agent and instrum...

We prove two generalizations of results appearing in [4] involving metrical completeness and R–buildings. Firstly, we give a generalization of the Bruhat–Tits fixed point theorem also valid for non-complete R–buildings, but with the added condition that the group is finitely generated. Secondly, we generalize a criterion which reduces the problem of completeness to the wall trees of the R–build...

In this paper, we firstly present a general expression for the entries of the th r   N r power of certain -square n are complex tridiagonal matrix, in terms of the Chebyshev polynomials of the first kind. Secondly, we obtain two complex factorizations for Fibonacci and Pell numbers. We also give some Maple 13 procedures in order to verify our calculations.

Immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. Accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (HSP), fibroblast growth factors (FGF) and transferrin receptors (TF-R) in 22 samples ...
