Abstract
Potentio-dynamic polymerization of buffered urease and pyrrole monomer onto carbon papers was conducted to fabricate an immobilized urease electrode for measuring the urea concentration. The potentiometric response corresponding to ammonia, the product formed from the urease catalyzed urea reaction, was employed for the urea concentration measurement. …

Group A Streptococcus (GAS) is a common pathogen for pharyngitis, impetigo, myositis, and lethal streptococcal toxic shock syndrome (STSS). It infects hosts through a number of paths: nasal, pharyngeal, and dermal. GAS contains various virulence factors which facilitate its infection and dissemination. SPE B is an important streptococcal pyrogenic exotoxin in GAS. …

This paper focuses on the object construction in Hainan Min. The data are gathered from our field work on Hainan Island. People in Hainan Island mostly speak Chinese, especially Southern Min dialects. Hainan Min is assumed to be a branch of Southern Min dialects. Min dialects, including Southern Min, have been widely investigated in previous research. In addition, Southern Min serves as a very popular topic for Taiwanese linguists. …

Techniques of nanoparticle detection have improved significantly for the demands of unprecedented high resolution in nanotechnologies.  Information about the spatial distribution and chemical identity of nanoparticles provide vital information for both nano- and bio-sciences.  Near-field imaging techniques with sub-wavelength spatial resolution offer fast, non-invasive and highly sensitive detections for wide variety of materials [Refs. 1-4]. …
