ii ABSTRACT A dual-channel directional digital hearing aid (DHA) front-end using a fully differential difference amplifier (FDDA) based Microphone interface circuit (MIC) for a capacitive Micro Electro Mechanical Systems (MEMS) microphones and an adaptive-power analog font end (AFE) is presented. The Microphone interface circuit based on FDDA converts the capacitance variations into voltage sig...

OBJECTIVES Twenty-five MRSA ST398 isolates from cases of bovine clinical mastitis and two isolates from farm personnel collected from 17 dairy farms in Germany were investigated for genetic relatedness, antimicrobial resistance and virulence properties. METHODS Genomic relationships were determined by ApaI PFGE, spa typing, SCCmec typing and dru typing. Antimicrobial resistance phenotypes wer...

From 1996 to 2001 a total of 467 Staphylococcus hyicus isolates from exudative epidermitis (EE) in pigs in Denmark were examined for susceptibility to 13 different antimicrobial agents. The presence of selected genes encoding macrolide (erm(A), erm(B) and erm(C)), penicillin (blaZ), streptogramin (vat, vga, vga(B), vat(B), vat(D) and vat(E)), streptomycin (aadE) and tetracycline resistance (tet...

Thioredoxin reduces disulfide bonds, thus regulating activities of target proteins in various biological systems, e.g., inactivation of inhibitors of starch hydrolases and proteases in germinating plant seeds. In the three-dimensional structure of a complex with barley α-amylase/subtilisin inhibitor (BASI), two loops in barley thioredoxin h2 (HvTrxh2), containing an invariant cis-proline ((86)E...

This research is based on the phenomenon of importance urban service spaces for tourist areas and users in them. For example, Singkawang City area that has been developed crowded with visitors Hongkong Market area. a destination form row commercial culinary buildings along Jl. Budi Utomo, Setia surrounding streets. Seeing city space areas, it necessary to optimize which relatively easy communit...

A variety of clinical manifestations of mercury intoxication may be encountered depending mainly upon the mercurial involved. Inhalation of elemental mercury results in pulmonary, central nervous system (CNS) and kidney damage. The CNS damage produces a spectrum of behavioural and neurological deficits. Ingestion of inorganic mercurials may, because of their corrosive nature, produce devastatin...

In this paper, an ultra low-voltage and low-power exponential V-1 converter is developed, using Taylor series expansion for realizing the exponential characteristics. The new CMOS exponential V-I converter is based on the composite NMOS transistors. The newly proposed appronmation function based on Taylor’s concept is used to extend the dB-linear output current range. In a 0.25 pm CMOS process,...
