let $(r,m)$ be a commutative noetherian local ring, $m$ a finitely generated $r$-module of dimension $d$, and let $i$ be an ideal of definition for $m$. in this paper, we extend cite[corollary 10(4)]{p} and also we show that if $m$ is a cohen-macaulay $r$-module and $d=2$, then $lambda(frac{widetilde{i^nm}}{jwidetilde{i^{n-1}m}})$ does not depend on $j$ for all $ngeq 1$, where $j$ is a minimal ...

introduction: radioimmunotherapy (rit) is a very promising new therapy for the treatment of recurrent b-cell non-hodgkin's lymphoma (nhl). iodine-131 is the most frequently used nuclide in clinical rit, but its usefulness has been limited by dehalogenation of monoclonal antibodies labeled via conventional methods. to circumvent this problem, we have synthesized a tri-peptide consisting of non-m...

carbapenemase producing bacteria frequently possess resistance mechanisms to a wide-range of antibacterial agents, and are associated with high mortality and morbidity rates. some enzymes like extended-spectrum β-lactamase (esbl), new delhi metallo-beta-lactamase-1 (ndm-1), klebsiella pneumoniae carbapenemase (kpc), and oxa-producing enterobacteriaceae are very important in frequently isolated ...
