This study was conducted to characterize virulence genes of Escherichia coli isolates from water, sediment, fish, and crab in Aby Lagoon. Serogrouping was performed by EPEC antisera in 113 E. coli strains. The presence of diarrhea-associated genes (eae, stx, AggR, elt, and est) was assessed by multiplex PCR using specific primers. Based on the multiplex PCR, sixty-two isolates (42 from water, 1...

In today's multicarrier modulation systems such as orthogonal frequency division multiplexing (OFDM) or discrete multitone (DMT), modulation is accomplished digitally by the use of the inverse discrete Fourier transform (IDFT). Instead of the IDFT, any other orthogonal transform can be used. In this paper a multicarrier scheme based on extended lapped transforms (ELT) is investigated. With the ...

Performance of AO systems on ELTs depends not just on seeing; other parameters such as strength of high-altitude turbulence are more relevant for the laser tomography. Nights good for some instruments are not so good for others, so there is a clear advantage to go from the simple queue scheduling on seeing to a more complex strategy of selecting in a multi-parameter space. The need to know thos...

A SAGE library was prepared from hand-dissected intestines from adult Caenorhabditis elegans, allowing the identification of >4000 intestinally-expressed genes; this gene inventory provides fundamental information for understanding intestine function, structure and development. Intestinally-expressed genes fall into two broad classes: widely-expressed "housekeeping" genes and genes that are eit...

Burkholderia pseudomallei is a Gram-negative soil bacterium that infects both humans and animals. Although cell culture studies have revealed significant insights into factors contributing to virulence and host defense, the interactions between this pathogen and its intact host remain to be elucidated. To gain insights into the host defense responses to B. pseudomallei infection within an intac...

Determining the absolute chronology of ceramic artifacts has significant implications for archeological and historical research. Wilson, Hall et al. recently suggested a new technique for direct absolute dating of archeological ceramics based on a moisture-induced chemical reaction, called rehydroxylation (RHX) dating. RHX dating proceeds by measuring the mass of chemically combined water in th...

This article argues that the teaching of English as an international language (EIL) should be based on an entirely different set of assumptions than has typically informed English language teaching (ELT) pedagogy. To begin, several defining features of an international language are described. Because these features have altered the nature of English itself, the author maintains that the pedagog...

BACKGROUND External laryngeal trauma (ELT) is a rare but clinically important injury. OBJECTIVE To perform the first population-based, time series analysis of the epidemiology, management, and outcomes of ELT using an 11-state, inpatient sample database containing more than 54 million patients. PATIENTS Three hundred ninety-two patients with a primary or secondary diagnosis of ELT were iden...

This paper discusses the leading role of Chinese educators in English Language Teaching (ELT) for young learners. English is a global language. ELT for children becomes especially popular in China when English was officially considered compulsory at primary school in 2001. National identity is the presentation of cultural identity, and alien culture helps children understand native culture from...

The aim of this study is to provide normative data for a phonological alternating task (FAT), a semantic alternating task (SAT) and an excluded letter task (ELT). The tasks were administered to 146 Flemish-speaking, cognitively healthy elderly. Data from 102 were used and were classified according to the significant variables. Subsequently, these tasks were administered to seven patients diagno...
