The notion of noncrossing linked partition arose from the study of certain transforms in free probability theory. It is known that the number of noncrossing linked partitions of [n+1] is equal to the n-th large Schröder number rn, which counts the number of Schröder paths. In this paper we give a bijective proof of this result. Then we introduce the structures of linked partitions and linked cy...

A novel sulfonated polybenzimidazole/organoclay (Cloisite-30B) (SPBI/clay) nanocomposite membranes was successfully synthesized based on aromatic diacide (1) and diaminobenzidine. Nanocomposite membranes were fabricated using 1, 4-bis (hydroxymethyl) benzene (BHMB) as cross-linker, and Cloisite-30B organoclay as the pseudo cross-linker. The cross-linked SPBI/clay nanocomposite membranes were pr...

conclusions albumin gradient method is the enrichment of y-bearing chromosome sperms. separation of spermatozoa by albumin gradient method, introduced by ericsson, is a suitable method for sex selection of male offspring. this technique is safe, because it neither requires toxic materials during sperm separation, nor involves embryo manipulation. objectives the study aimed to assess the separat...

there are many studies related to the production of a elisa kit for diagnosing virus infections. however, production of most kits depends on purification of whole virus particles, which involves the use of costly equipment and reagents. the purpose of this study was to check out if the anti-cp42 antibodies could be used as a diagnostic assay for detection of grapevine fanleaf virus (gflv). in t...
