In this study, we used plasmid profile analysis, XbaI macrorestriction with pulsed-field gel electrophoresis (PFGE), and PCR of the ipaH gene, to study the molecular characteristics of 183 Shigella spp. isolated during May 2000 to April 2003 from rectal swabs of patients with watery and/or bloody diarrhoea in a new industrialized area of Thailand. Among the 183 isolates, 167 were S. sonnei and ...

An outbreak situation of human listeriosis requires a fast and accurate protocol for typing Listeria monocytogenes. Existing techniques are either characterized by low discriminatory power or are laborious and require several days to give a final result. Polymerase chain reaction (PCR) coupled with high resolution melting (HRM) analysis was investigated in this study as an alternative tool for ...

In Sustainable Forest Management, decaying wood plays an important role in forest biodiversity, carbon balance and nutrient cycling. The management of this important component of forest ecosystems is limited by the fact that little is known about relationships between substrate quality and community structure of wood-inhabiting microorganisms. During decomposition, carbon stored in deadwood is ...

In many situations, a signal consisting of a single tone corrupted by additive white noise is available, and the frequency of the tone must be estimated. This problem has applications in communications, radar, sonar, measurements, adaptive control, speech processing etc [1], and it belongs to the wider class of spectrum estimation problems [2]. Both complex and real signals have been considered...

In recent years space geodetic techniques such as the Global Positioning System (GPS), Very Long Baseline Interferometry (VLBI), and Satellite Laser Ranging (SLR) have been collocated to address many applications in geoscience. While results from all these techniques are contaminated by various biases and errors, a commonmode signal has been found among the collocated results of GPS, VLBI and S...

This paper presents algorithms that allow the realization of multi-valued functions as a multi-level network consisting of minand max-gates. The algorithms are based on bi-decomposition of function intervals, a generalization of incompletely specified functions. Multi-valued derivation operators are applied to compute decomposition structures. For validation the algorithms have been implemented...

Astaxanthin is a carotenoid known for its powerful antioxidant properties. This study focused on isolating yeast strains capable of producing astaxanthin from flower and fruit samples collected in Thailand. Out 115 isolates, 11 were identified that produced astaxanthin. Molecular identification techniques revealed these isolates belonged to two species: Rhodotorula paludigena (5 isolates) Rhodo...

We present DEFENDER and illustrate the benefits of identifying promising query decompositions and efficient plans that combine results from federations of SPARQL endpoints. DEFENDER is a query decomposer that implements a two-fold approach. First triple patterns in a SPARQL query are decomposed into simple sub-queries that can be completely executed on one endpoint. Second, sub-queries are comb...

This study focus on the development agent of biological control based technologies used Trichoderma mix with bokashi fertilizer from agricultural waste. arranged in a randomized block design (RBD) factorial pattern, factor I is type decomposer microorganism that consisted three treatments (M1: EM4 decomposer, M2: M3: and Trichoderma), II waste, four (L1: soybean plant L2: rice crop L3: corn L4:...
