Escherichia coli morphotype E flagellar filaments have a characteristic surface pattern of short-pitch loops when examined by electron microscopy. Seven of the 50 known E. coli H (flagellar antigen) serotypes (H1, H7, H12, H23, H45, H49, and H51) produce morphotype E filaments. Polymerase chain reaction was used to amplify flagellin structural (fliC) genes from E. coli strains producing morphot...

A ring $R$ with identity is called ``clean'' if $~$for every element $ain R$, there exist an idempotent $e$ and a unit $u$ in $R$ such that $a=u+e$. Let $C(R)$ denote the center of a ring $R$ and $g(x)$ be a polynomial in $C(R)[x]$. An element $rin R$ is called ``g(x)-clean'' if $r=u+s$ where $g(s)=0$ and $u$ is a unit of $R$ and, $R$ is $g(x)$-clean if every element is $g(x)$-clean. In this pa...

This paper presents multifactor authentication method for securing access to e-banking systems in Nigeria using fingerprint recognition and SiteKey authentication. Fingerprint authentication is based on the notion of fingerprint individuality; the idea that fingerprint image of an individual is unique and can be used to uniquely identify him/her. SiteKey authentication on the other hand, uses a...

Weakly left ample semigroups form a class of semigroups that are (2; 1)-subalgebras of semigroups of partial transformations, where the unary operation takes a transformation to the identity map in the domain of. They are semigroups with commuting idempotents such that the e R-class of any element a contains a (necessarily unique) idempotent a + , e R is a left congruence, and the ample identit...

Grid is an e-Science project assisting life scientists to build workflows that gather and co-ordinate data from distributed, autonomous, replicated and heterogeneous resources. The provenance logs of workflow executions are recorded as RDF graphs. The log of one workflow run is used to trace the history of its execution process; however, by aggregating provenance logs of workflow reruns, or run...

The informatics infrastructure supporting the Information Society requires the aggregation of data about individuals in electronic records. Such data structures demand that individuals be uniquely identified and this is critical to the necessary processes of authentication, identification and enrolment associated with the use of e-Business, e-Government and potentially e-Democracy systems. It i...

We present certain new properties about the intersection numbers on moduli spaces of curves Mg,n. In particular we prove a new identity, which together with a conjectural identity implies the famous Faber’s conjecture about certain values of intersection numbers [1]. These new identities are much simpler than Faber’s identity and clarified the mysterious constant in Faber’s conjecture. We also ...
