In the ongoing fight against climate change, plastic pollution and diseases, scientists are turning to an unlikely ally - plants! Everyone knows plants are pretty cool. They create oxgyen for us to breathe (fairly essential) and provide us with trees to climb. But it turns out that platns can do a whole lot more than that too! Get ready to be amazed when you find out about the spinach that can detect landmines AND send emails and the glow-in-the-dark plants that might one day light your home. Perfect for anyone who loves nature and wildlife, as well as the scientists of the future - you won't look at plants and trees in the same way again!
During the last decade, many new concepts have been proposed for improving the performance of power rectifiers and transistors. The results of this research are dispersed in the technical literature among journal articles and abstracts of conferences. Consequently, the information is not readily available to researchers and practicing engineers in the power device community. There is no cohesive treatment of the ideas to provide an assessment of the relative merits of the ideas. Advanced Power Rectifier Concepts provides an in-depth treatment of the physics of operation of advanced power rectifiers. Analytical models for explaining the operation of all the advanced power rectifier devices will be developed. The results off numerical simulations will be provided to provide additional insight into the device physics and validate the analytical models. The results of two-dimensional simulations will be provided to corroborate the analytical models and provide greater insight into the device operation.
The advent of low temperature superconductors in the early 1960's converted what had been a laboratory curiosity with very limited possibilities to a prac tical means of fabricating electrical components and devices with lossless con ductors. Using liquid helium as a coolant, the successful construction and operation of high field strength magnet systems, alternators, motors and trans mission lines was announced. These developments ushered in the era of what may be termed cryogenic power engineering and a decade later successful oper ating systems could be found such as the 5 T saddle magnet designed and built in the United States by the Argonne National Laboratory and installed on an experimental power generating facility at the High Temperature Institute in Moscow, Russia. The field of digital computers provided an incentive of a quite different kind to operate at cryogenic temperatures. In this case, the objective was to ob tain higher switching speeds than are possible at ambient temperatures with the critical issue being the operating characteristics of semiconductor switches under cryogenic conditions. By 1980, cryogenic electronics was established as another branch of electric engineering."

The 21st century is often characterized as the age of globalization, with the world's economies becoming more and more interconnected at an unprecedented rate. And while the phenomenon of globalization isn't necessarily new, it has taken on a drastically different form since the 1980s: competition amongst multinational and global organizations is more intense, and non-Western multinationals are now emerging as important players in the global economy. Today, professional managers need to reconcile the opportunities and challenges associated with the rapid growth of Asian, Eastern European, and Latin American countries. To do so, adopting what's called 'the global mindset' is becoming an essential skill for managers within these global organizations. The key advantages of developing a global mindset are many. In Global Organizations: Challenges, Opportunities, and the Future, authors Rabi S. Bhagat, Annette S. McDevitt, and B. Ram Baliga offers an insightful and comprehensive overview of the most important issues today for managers looking to develop and nurture their own global mindset for their company's future. Global Organizations expertly provides readers with research- and evidence-based knowledge on the significance of developing a sophisticated global mindset regardless of national identity or geographic locale.

This is the first comprehensive resource of power device electrical characteristics in a cryogenic environment. Using theoretical and experimental knowledge from the literature, temperature dependence of fundamental silicon material parameters like intrinsic carrier concentration, carrier mobilities, lifetimes and bandgap narrowing was identified. The temperature dependent model of avalanche breakdown was developed using experimental data on numerous devices. A wide range of power devices, each with its own unique features, was chosen for theoretical and experimental analysis. Using these analyses, Schottky diodes, power MOSFETs, power BJTs, and power JFETs were optimized in the 300-77K temperature range. Cryogenic Operation of Silicon Power Devices presents the different characteristics of power devices operated below -55 C (220K). It provides data and physics based models for power devices operated at temperatures down to 77K for the first time within a single source. All commercially available devices have been included to provide comprehensive coverage.Also, a fundamental analysis of devices identifies the suitability of various devices to applications requiring cryogenic operations. A quantitative analysis of the relative strengths and weaknesses of these devices is also presented.

Clinical practice consensus guidelines for management of heart failure are available from the American Heart Association/American College of Cardiology, Heart Failure Society of America, Canadian Cardiovascular Society, and European Society of Cardiology. The guidelines from these organizations, based on evidence from clinical trials and expert agreement, are largely concordant and provide useful information for practitioners. Yet, the organization of the guidelines may confound efforts by a practitioner to determine which specific intervention, or combination of interventions, are most appropriate for an individual patient. As part of the Oxford American Cardiology Library, Heart Failure utilizes the staging of heart failure proposed by the ACC/AHA guidelines as a framework to develop a systematic approach for diagnosis and treatment across a broad spectrum of clinical presentations. Each chapter addresses a different stage in the progression of heart failure and provides a patient-centered description of the appropriate diagnostic and treatment options for that setting. Each chapter also incorporates discussion of the diagnosis and treatment options for both low ejection fraction heart failure patients and preserved ejection fraction heart failure patients, of which the latter group comprises at least 50% of all heart failure cases in clinical practice. Heart Failure restructures the information in the clinical guidelines to a format that is more accessible and clinically useful to practitioners.

Dyslipidemia affects almost half of American adults and is the most prevalent manageable risk factor for atherosclerosis. Lipid disorders often co-occur with other prevalent conditions such as diabetes and kidney disease; they are also often a concern with certain medication regimens (such as anti-retroviral and certain anti-psychotic agents). Proper treatment of dyslipidemia can reduce the risk of peripheral arterial disease, revascularization procedures, nonfatal myocardial infarction, stroke, and cardiac death. However, only 20% of adults meet the national guidelines for cholesterol control.
