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main emphases were on the cognitive aspects of learning and traditional instructions of teaching in the classroom using outdated and conventional techniques.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...

The goals of this exploratory study were to determine students' assessment of portable digital video instruction (using the Apple iPod) and to compare examination performance among groups of predoctoral dental students who did and did not utilize portable digital video instruction as a supplement to a conventional pediatric behavior management lecture. Dental students received a one-hour lectur...

Outlier detection in mixed attribute datasets has proved to be a challenging task required in real world applications. Most existing algorithms for outlier detection do not consider the interactions between categorical and numerical attributes. The Pattern based Outlier Detection (POD) algorithm (Zhang & Jin, 2011), has had considerable success in the detecting outliers by analysing such intera...

Non-catalytic direct electron transfer (DET) signal of Compound I of horseradish peroxidase (POD) was first detected at 0.7 V on POD/carbon nanotube mixture-modified electrodes. Excellent performance of DET-type bioelectrocatalysis was achieved with POD immobilized with glutaraldehyde on Ketjen Black (KB)-modified electrodes for H2O2 reduction with an onset potential of 0.65 V (vs. Ag | AgCl | ...

Changes in peroxidase (POD), superoxide dismutase (SOD), catalase (CAT) and phenylalanine ammonia-lyase (PAL) activities were studied during Chimonanthus praecox seed maturation. According to our findings the protein content increased steadily from 8 to 12 weeks after flowering, and thereafter decreased significantly. Similarly, SOD and POD activities increased gradually up to 12 weeks after fl...
