Simultaneous determination of serum flecainide and its oxidative metabolites was carried out by using high performance liquid chromatography (HPLC) equipped with conventional octadecylsilyl silica (ODS) column and fluorescence detector. Flecainide and its metabolites, m-O-dealkylated flecainide (MODF) and m-O-dealkylated lactam of flecainide (MODLF) in serum were extracted with ethyl acetate. T...

The modABC gene products constitute the molybdate-specific transport system in Escherichia coli. Another operon coding for two proteins which diverges from the modABCD operon has been identified. The first gene of this operon codes for a 262-amino-acid protein, designated ModE (28 kDa), and the second genes codes for a 490-amino-acid protein. ModF (54 kDa). The role of ModF has not yet been det...

We consider a set of M images, whose pixel intensities at a common point can be treated as the components of a M-dimensional vector. We are interested in the estimation of the modulus of such a vector associated to a compact source. For instance, the detection/estimation of the polarized signal of compact sources immersed in a noisy background is relevant in some fields like Astrophysics. We de...

OBJECTIVES To investigate the hypothesis that there is continuing subclinical M. leprae infection, contributing to ongoing transmission of leprosy in Phra-Pradaeng Colony. DESIGN A sero-epidemiological survey was carried out in Phra-Pradaeng Colony, Thailand between May and August 2005. The clinical and serological examinations were conducted in 398 people, aged 3-84 years (average 50 years),...

1. The Problem I begin with a gloomy observation on monastic education by Phra Prayud Payutto (1939) of Thailan whom Tambiah calls "a brilliant scholar-monk" [1]. Payutto said in 1984: "The present state of m education is similar to a sky which has some spots of sunshine, but is in fact full of cloud. The sky is n clear. When monks themselves see the dull and overcast sky they may feel disheart...

One of the major problems facing Thai education at the university level is that of academic dishonesty. While newspapers often report upon individual and group cases of university-level cheating, there has been little research done to determine the reasons behind the dishonesty of Thai students as well as the extent and implications. In addition, surveys have shown that a majority of both stude...

The 26th December 2004 Indian Ocean Tsunami (IOT) emanated from an Mw 9.2 earthquake that generated a 1600 km-long rupture along the Sumatran Megathrust and generated tsunami waves up to 30 m high. The IOT directly impacted the Bay of Bengal and east Africa, with over 283,000 people perishing. At the time, this catastrophic event was considered unprecedented and sparked intense investigations t...

According to a result of H. Cartan (cf. [5]), the homotopy of a simplicial commutative algebra is equipped with divided power operations. In this paper, we provide a general approach to the construction of such operations in the context of simplicial algebras over an operad. To be precise, we work over a fixed field F, and we consider operads in the category of F-modules. An operad is an algebr...

Electromigration, as one of the main failure mechanismus of VLSI circuits, is of great concern to microelectronics industry. The effects of grain morphology as well as texture can be studied on a mesoscale by Automated Crystal Orientation Mapping (ACOM) in the SEM since it provides a detailed description of the microstructure. Textural functions (e.g. pole figures, ODF, MODF), statistical param...

An insight into the folate nutritional status of the population is important from a public health perspective. The protective effect of folate against neural tube defects (NTDs) is widely recognized. To assess the health and nutritional status, especially folate status, of vulnerable hill-tribe groups, a cross-sectional study was conducted on 197 schoolchildren and 136 women of childbearing age...
