We designed a chemical method for measurement of iohexol concentrations (4) and characterized its pharmacokinetics in man in relation to a number of other contrast media (5, 6). We found that is indeed a suitable marker for glomerular filtration rate (GFR): after intravenous injection, it is quantitatively recovered in the urine; the elimination occurs by glomerular filtration, with no signs of...

BACKGROUND Throughout the last decade of the twentieth century, Lithuania had the highest suicide rates in Europe among both men and women aged 25-64 years. The rates increased from 1986 until 1995, but later there was a slight decrease. This paper describes the trends in suicide deaths in urban population in Lithuania by gender, dates and suicide method over the period 1984-2003. METHODS Dat...

594 CLINICALCHEMISTRY,Vol. 30, No. 4, 1984 that the preservatives used had no effect on the MCP-NAG assay but that NAG activity declined when the urine pH was >8.0 and this decline became more marked on storage. This test kit provides a rapid method of estimating urinary NAG and can be used with a simple spectrophotometer. The lack of any reference standard is a drawback, but we understand it i...

In this paper, we propose a Transformation-Based Learning (TBL) method on generating the Korean standard pronunciation. Previous studies on the phonological processing have been focused on the phonological rule applications and the finite state automata (Johnson 1984; Kaplan and Kay 1994; Koskenniemi 1983; Bird 1995). In case of Korean computational phonology, some former researches have approa...

The σ -convergence and σ -core of a real bounded sequence were introduced in [R. Raimi, Invariant means and invariant matrix methods of summability, Duke Math. J. 30 (1963) 81–94] and [S.L. Mishra, B. Satapathy, N. Rath, Invariant means and σ -core, J. Indian Math. Soc. 60 (1984) 151–158], respectively. In this work, we extend these ideas to double sequences. c © 2006 Elsevier Ltd.

Performance standards have important consequences for all the stakeholders in assessment of L2 academic writing. These not only describe level writing performance but also provide a basis making evaluative decisions on Such high-stakes role requires enhancement objectivity standard setting procedure. Accordingly, this study aims to shed light upon usefulness Objective Standard Setting (OSS) met...
