Buch. Zustand: Neu. Neuware -In the world of physical science, important physical quantities like sound, pressure, electrical current, voltage, and electromagnetic fields vary with time. Such quantities are labeled as signals/waveforms and include oral signals, optical signals, acoustic signals, biomedical signals, radar, and sonar. Time-frequency analysis is a vital aid in signal analysis, which is concerned with how the frequency of a function (or signal) behaves in time, and it has evolved into a widely recognized applied discipline of signal processing. This book discusses the Fourier transform (FT), which is one of the most valuable and widely used integral transforms that converts a signal from time versus amplitude to frequency versus amplitude. It is one of the oldest tools in the time-frequency analysis of signals. The book includes five chapters that discuss general Fourier transforms as well as new and novel transforms such as hybrid transforms, quadratic-phase Fourier transforms, fractional Fourier transforms, linear canonical transforms, and more.Books on Demand GmbH, Überseering 33, 22297 Hamburg 98 pp. Englisch.

Buch. Zustand: Neu. Neuware -Plastics are crucial materials that are used in daily life. They are manufactured and used until they become waste that negatively impacts the environment and public health. These plastic wastes break down into small particles known as microplastics (MPs) via changes in environmental conditions (i.e., sunlight, temperature, weathering, and irradiation). This reduction in size increases the toxic potential of MPs. This book provides a comprehensive overview of MPs, including the challenges and advances in their effective removal from our environment.Books on Demand GmbH, Überseering 33, 22297 Hamburg 242 pp. Englisch.

Buch. Zustand: Neu. Neuware -Sexual education is a worldwide concern that intersects with various attitudes, values, and cultural norms. It is an area of life that has for many years been kept private, but now there is recognition that there is a need to support people, especially young people in modern societies. The way sexual education is taught and applied within institutions shapes the way we understand and approach human sexuality. Various societies have chosen various means to provide sexual education both at school and to the wider society. There is still much more development and support needed, however. We can begin to identify strategies for overcoming challenges in sex education, promoting healthier attitudes, and empowering individuals to make informed decisions about their own bodies and relationships. This book is organized into three sections. The first section focuses on issues in sexual education, such as sexual harassment, sexuality and relationship education and advocacy by people with disabilities, future challenges, and sex differences in physical attractiveness. The second section focuses on the means of sexual health education interventions, including the use of technology. The last section includes a chapter on sex education and the invisibility of intersex people in the curriculum.Books on Demand GmbH, Überseering 33, 22297 Hamburg 144 pp. Englisch.

It addresses recent advances in induction motors, optimal solutions in field-oriented control, the association of converters to induction motors, dynamic analysis, optimized design of synergetic control, fault-tolerant control, mathematical modeling, an adaptive system scheme for a sensorless drive, modeling, and simulation of a system with inter-turn faults, sensorless speed observer for industrial drives, and induction motor applications in electric vehicles. This book is useful for undergraduates, graduate students, researchers, professors, and field engineers due to its combination of both theoretical coverage and real-world application concepts.Books on Demand GmbH, Überseering 33, 22297 Hamburg 222 pp. Englisch.

Buch. Zustand: Neu. Neuware -Hemodialysis (HD) is the commonest form of kidney replacement therapy worldwide with a prevalence rate close to 90%. Despite significant improvements in HD techniques and related devices and solutions, the cardiovascular and all-cause mortality of HD patients remains unacceptably elevated. More recently, there have been significant improvements in the creation and maintenance of vascular access as well as the knowledge of types, classification, and monitoring of uremic toxins and their relationship with inflammation, atherosclerosis and vascular classification, and cardiovascular and all-cause mortality. More interesting is the innovation in dialysis membranes/dialyzers, which resulted in the creation of the medium cut-off membrane, which enables the safe, simple, and effective removal of middle- and large-sized uremic toxins. This type of HD treatment is called expanded hemodialysis (HDx) therapy, which so far has resulted in significant improvement in the quality of life of HD patients as well as reductions in hospitalization, medications, and non-fatal cardiovascular events. Updates on Hemodialysis discusses these innovations and how they can be used to improve daily practice and achieve the best possible medical outcomes in HD patients.Books on Demand GmbH, Überseering 33, 22297 Hamburg 210 pp. Englisch.

Buch. Zustand: Neu. Neuware -High levels of toxic elements have harmful effects on all aspects of the environment (water, air, plants, etc.). Trace elements, many of which are heavy metals, can compromise soil quality, cause toxicity to plants, and ultimately contaminate the food chain.

Buch. Zustand: Neu. Neuware -Producers spend a great deal of money, natural resources (especially water and soil), labor, and time every year in order to feed the world¿s population. However, almost one-third of the products produced as a result of all these efforts are lost before reaching consumers due to postharvest losses, which threaten both the food supply and agricultural sustainability. For this reason, it is extremely important to prevent postharvest losses of fruits and vegetables. In this context, this book provides general and new information about the physiology of postharvest losses and the latest technological developments in postharvest systems. Each chapter provides up-to-date information about the postharvest physiology and technology of fruits and vegetables for students, teachers, professors, scientists, farmers, food packers and sellers, and entrepreneurs engaged in the fresh food preservation industry.Books on Demand GmbH, Überseering 33, 22297 Hamburg 372 pp. Englisch.
