Pyruvic oxime dioxygenase (POD), a key enzyme in heterotrophic nitrification, was purified from Alcaligenes faecalis, and the molecular and catalytic characteristics were reexamined. POD was purified as the homotetramer of the subunit whose molecular weight was 30,000. The deduced amino acid sequence of POD was homologous with a class II aldolase that has been regarded as the Zn(II)-dependent e...

The previously reported activity of benzyladenine and selected other cytokinin analogs to increase pod set in soybean (Glycine max [L.] Merr.) was further investigated to define the structure-activity relationship and evaluate the effects of the cytokinins on yield parameters. Enhancement of pod set was found to be greatest with N-6 saturated alkyl substituted analogs, and was only weakly assoc...

This study focuses on stabilizing reduced order model (ROM) based on proper orthogonal decomposition (POD) and on improving the POD functional subspace. A modified ROM that incorporates directly the pressure term is proposed. The ROM is stabilized using Navier-Stokes equations residuals and exploiting ideas similar to the variational multiscale method. The POD functional subspace is improved th...

AIM Pathophysiological disorders after surgery might be related to postoperative delirium (POD). This study was designed to elucidate the pathogenesis of POD in elderly oral cancer patients by determining the perioperative kinetics of inflammatory cytokines, cortisol, and amyloid β1-40 (Aβ1-40). METHODS A total of 257 elderly oral cancer patients who underwent tumor resection surgery were sel...

The number of people over 65 is increasing and those over 65 requiring surgery will likewise increase. Post-operative delirium (POD) affects up to 47% of patients undergoing surgery and is more prevalent in older people. Importantly, POD is associated with increased morbidity, mortality, length of stay and care home placement. There is evidence that specialist geriatrician input reduces POD but...

In the present work, co-immobilization of cholesterol oxidase (COD) and horseradish peroxidase (POD) on perlite surface was attempted. The surface of perlite were activated by 3-aminopropyltriethoxysilane and covalently bonded with COD and POD via glutaraldehyde. Enzymes activities have been assayed by spectrophotometric technique. The stabilities of immobilized COD and POD to pH were higher th...

The construction of reduced-order models for parametrized partial differential systems using proper orthogonal decomposition (POD) is based on the information of the so-called snapshots. These provide the spatial distribution of the nonlinear system at discrete parameter and/or time instances. In this work a strategy is used, where the POD reduced-order model is improved by choosing additional ...

This article analyzes the distribution of financial value from innovation in the global supply chains of iPods and notebook computers. We find that Apple has captured a great deal of value from the innovation embodied in the iPod, while notebook makers capture a more modest share of the value from PC innovation. In order to understand these differences, we employ concepts from theories of innov...

Steven Levy used the shuffle feature of the Apple iPod as a metaphor for the digital age. Newspapers used to be the medium for getting news in one physical bundle, but today people can “shuffle” between news sites. Similarly, thanks to the Internet, shoppers can shuffle between stores, no longer constrained by what is in a mall. Levy postulated that even Apple did not realize the transformative...

In early days the main emphases were on the cognitive aspects of learning and traditional instructions of teaching in the classroom using outdated and conventional techniques. But today in this world of constant innovations and discoveries, scientists and gadget-experts are continuously searching for one or the two technological devices a day. Nodoubt technology has made our life much easier an...
