Phosphonothrixin (1) is a novel herbicidal agent produced by Saccharothrix sp. ST-888. This unique compound possessing a C-P bond and an isoprene unit was determined to be 2-hydroxy-2-hydroxymethyl-3-oxobutyl-phosphonic acid. Unusually rapid proton-deuterium (H-D) exchange of the methyl ketone unit of this antibiotic in D2O solution was observed. Phosphonothrixin can be classified as a new type...

We present the results of high-resolution mid-infrared observations of the source NGC3576 IRS 1. Near diffraction-limited images were taken at the Gemini South Observatory through OSCIR’s filters N (10.8 μm), 7.9, 9.8, 12.5 and IHW18 (18.2 μm). The source IRS1 was resolved into 3 sources for the first time at mid-infrared wavelengths. For each source we constructed the SED from 1.25 to 18 μm, a...

Tropone and its derivatives have fascinated organic chemists for well over 50 years. Early theoretical work suggested that tropone may represent a new type of aromatic system, which would possess resonance stabilization due to fact that it has Huckel’s sextet electron system. Another significant reason for the interest in the ring systems of tropones is that they represent the key structural el...

The paper reports a study into consumers’ ‘soft’ usability problems they experience using electronic household products. These problems cannot be traced back to a specification violation failure, classified as no failure found (NFF). The aim of this study is to find a relationship between consumers’ soft usability problems and their personal characteristics, encompassing demographical and cogni...

Web-based intelligent is key to achieve global leadership in six-sigma product aftermarket service and manufacturing productivity for the 21st century. The need to improve the understanding of product’s performance for aftermarket service will lead to e-intelligence for quality maintenance and product development. With the proper integration of e-intelligence into products, manufacturing and se...

We have been undertaking a programme on the Gemini 8-m telescopes to demonstrate the power of integral field spectroscopy, using the optical GMOS spectrograph, and the new CIRPASS instrument in the near-infrared. Here we present some preliminary results from 3D spectroscopy of extra-galactic objects, mapping the emission lines in a 3CR radio galaxy and in a gravitationally lensed arc, exploring...

The enabling of data produced by product embedded sensor devices for use in product development could greatly benefit manufactures, while opening up new business opportunities. Currently products such as cars already have embedded sensor devices, but the data is usually not available for analysis in real-time. We propose that a world-wide, inter-organizational network for product data gathering...

In terms of improving animal productivity and profitability, the use of monensin and related ionophoric antibiotic growth promoters has unarguably been one of the major successes of rumen microbiology in contributing to ruminant nutrition (Russell & Strobel, 1989). Addition of ionophoric antibiotics to ruminant diets has been associated with beneficial changes in the ratio of volatile fatty aci...
