  • Nuclear power approximately supplies a sixth of the world's electricity and considers as the major source of "carbon-free" energy today. With growing concerns aboutglobal warming, it is not surprising that governments and power providers around the world are considering building a substantial number of additional nuclear power plants. These plants have demonstrated remarkable reliability and efficiency with the help of extensive research work and sharing operational practical experience.

  • It is my great pleasure to be an editor for InTech Open Access publisher, one of the most successful Open Access book publishersin the fields of science, technology and medicine. Sensor arrays are used to overcome the limits of simple and/or individual conventional sensors. Obviously, it is more complicated to deal with some issues related to sensor arrays, e.g. signal processing, than the conventional sensors. Some of the issues are addressed in this book, with emphasis on signal...

  • The laws of random chance, however, also indicate that, after a period of above-average performance, a fund will probably return to normalcy at best (referred to by mathematicians as a "reversion to the mean"). 2 Furthermore, after an influx of new money, the fund's outlook may be even less promising than normal. The formerly successful fund may be more likely than other funds to underperform. The source of the underperformance...

  • Most of the epidemiological studies which compared breast cancer risk of active smokers to women who were not smokers (regardless of their passive smoke exposure) have found no association of smoking and breast cancer risk. But several studies found that women who smoked had a decreased breast cancer risk. It is not uncommon for epidemiological studies to come to different assessments of health risk, especially when, as in these studies, the associated risk is not large.

  • This book covers fundamental aspects of electric circuits that form the core of many engineering disciplines. In particular, basic circuit elements and their characteristics are presented when connected in an electric network. In addition, techniques to analyse and solve electric circuits are explained in a simple manner and examples are shown to demonstrate each strategy. DC as well as AC circuit analysis is provided with a brief account of filters in the end.

  • Omnichannel marketing is about being present or available across the consumer’s behavioral path: each potential contact point integrated with all others. The concept started in the retail sector where this behavioral path is easily tracked across online, offline and mobile touchpoints (both marketing and transactional). The digital arena will represent the first stage of more brands adopting an omnichannel mindset, as social and mobile data sources are blended with offline brand experiences.

  • The information is collected from these sources by either active collection or passive reporting. Active collection involves registry personnel actually vis- iting the different sources and abstracting the data on special forms. This is the usual method in registries in developing countries. Passive reporting involves health-care workers completing the notification forms developed and distributed by the registry, or sending copies of discharge abstracts to the registry. A mixture of both procedures, with an emphasis on the latter, is followed in most registries in developed countries.

  • Active follow-up usually means that the registry attempts to contact physi- cians or patients on a regular basis to see if the patient is still alive. Because this is expensive, many registries rely on passive follow-up, matching with death certificates and assuming patients are alive otherwise. Mixed systems use death certificates plus updating the ‘date last known alive’ from hospital admissions, consultations, and other sources of data. Active follow-up of the patients is usually very difficult in developing coun- tries.

  • The tobacco smoke a smoker inhales is different from the smoke inhaled by those nearby. The major source of passive smoke is from the burning of the cigarette rather than what is exhaled by smokers. Both types of smoke contain thousands of chemicals. The chemicals present in both these types of smoke are similar, but the concentrations of the chemicals are different. Many of the toxic chemicals in tobacco smoke are found in higher concentrations in the tobacco smoke as it leaves the cigarette compared to inhaled smoke; in some cases, the concentrations are far higher.
