In this paper, we show that for any two bases B and B of a regular matroid, there is an element e ∈ B such that there is a unique element f ∈ B for which both (B\{e}) ∪ {f} and (B\{f}) ∪ {e} are bases of M. This solves a problem posed by White in 1980.
This paper compares the effects of exchange rate movements on the risk/return characteristics of direct investment property assets for non-domestic investors with particular emphasis on economic and translation risk. The correspondence between four property markets (US, UK, Canada, and Australia) and the appropriate exchange rates are examined in order to analyse the pattern and temporal stabil...
We show that cohopfian modules with finite exchange have countable exchange. In particular, a module whose endomorphism ring is Dedekind-finite and π-regular has the countable exchange property. We also show that a module whose en-domorphism ring is Dedekind-finite and regular has full exchange. Finally, working modulo the Jacobson radical, we prove that any module with the (C 2) property and a...
مهار رشد رده سرطانی K562 با استفاده از کالپروتکتین (Calprotectin) نوترکیب انسانی در شرایط آزمایشگاهی
Background: Recombinant human Calprotectin is a protein that has inhibitory effect on the growth of cancer. This substance could use as a marker or therapeutic agents for cancer. The goal of this study was to evaluate the anti-tumor property of recombinant human Calprotectin on K562 cell line. Methods: Recombinant human Calprotectin was cloned and purified in E. coli. Then, different concent...
