OBJECTIVE To test whether a fat reduced diet rich in soluble dietary fibre, antioxidant vitamins, and minerals reduces complications and mortality after acute myocardial infarction. DESIGN Randomised, single blind, controlled trial. SETTING Primary and secondary care research centre for patients with myocardial infarction. SUBJECTS 505 patients with(More)
To improve the diagnosis of Salmonella typhi infection, a polymerase chain reaction (PCR) assay was developed for the amplification of the dH flagellin gene of S typhi. Primers were designed from dH flagellin gene sequence which will give an amplification product of 486 base pairs. In tests to study the specificity of the assay, no amplification was seen in(More)
The bacteriological and clinical findings of 18 cases of brain abscess are presented. Identification and antimicrobial susceptibility of anaerobic strains was performed both by conventional methods and the newer RapID ANA II panel and E-test methods, respectively. Characterization of the anaerobic isolates was done by restriction fragment length(More)

This paper presents the design of a Gallium Arsenide MESFET based active Gilbert mixer in X-band (7.5 – 9 GHz). Gilbert mixer core fed through passive lumped baluns at RF and Local oscillator (LO) inputs have been used to achieve an isolation of better than 30 dB. An active combiner is designed at low frequency IF (Intermediate frequency) output.(More)
Experiments were conducted to study the performance of circular and square tank surface aerators on the oxygen transfer coefficient and to a limited extent on power requirements. All the tanks are geometrically similar except for their shapes. They consist of a rotor of diameter, D, fixed with six flat blades rotating with a speed, N, in pure waters of(More)
