Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The idea of sharing a medium between signals originated sometime in the late 18th century and first appeared in wired telephone systems in the United States in the early 19th century. Multiplexing (MUX), a method by which multiple analog or digital signals are combined into one signal over a shared medium, increases the capacity of the communication channel by dividing it into several logical channels, one for each message signal or data stream to be transferred. On the receiver side, the reverse process known as de-multiplexing (DEMUX) helps to extract the original channel. This book examines recent advances and novel applications in MUX and DEMUX. It discusses how MUX is applied in free-space optics (FSO) applications and how 5G and 6G signals benefit from MUX, among other topics. 140 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book addresses some of the major challenges of food systems associated with a diversity of agricultural contexts and priorities. It contributes to the conversation on global food and nutrition security by unpacking the intertwined connections between food system resilience, food policies, and global food markets. The contributing authors provide careful analyses of how shocks to food systems (e.g., COVID-19 pandemic lockdowns) and crises to global food systems (e.g., the global food price crisis of 2008) have disrupted the food value chains in ways that undermine global initiatives to achieve food and nutrition security for all. The book is divided into two sections. Section 1 focuses on global food systems transformation with the goal of moving towards resilience. Two chapters in this section employ a global context approach to address the key factors undermining food systems¿ resilience and sustainability. Section 2 presents case studies drawn from Africa, Asia, and Europe with different pathways for the transition to food systems resilience, highlighting the importance of policy approaches as well as smart and innovative strategies to ensure the production of nutritious foods at affordable costs, the reduction of food wastage, and the valorization of sub-products. 230 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Modern medicine is impossible without antibiotics, but global antibiotic usage has led to the development of increasing numbers of multi-drug resistant (MDR) bacteria. Thus, we still have problems with infectious disease treatment despite an arsenal of antibiotics. This has forced researchers to develop new drugs that will be effective against resistant bacteria. Some of these prospective molecules are antimicrobial peptides (AMPs), which are an important component of the innate immune system of various organisms in nature. Currently, more than 3,000 AMPs have been reported with different activities against different bacterial species including resistant phenotype bacteria. AMPs display remarkable structural and functional diversity that is not completely understood. As such, this book presents a comprehensive overview of AMPs and their mechanism of action against MDR bacteria.Books on Demand GmbH, Überseering 33, 22297 Hamburg 166 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book presents several new, important explanations for dark matter, all dissimilar to the discredited subatomic particle-like but invisible matter. One chapter presents evidence that abundant cold hydrogen, baryonic matter, is the source of the missing gravity. Another chapter suggests that dark matter is better explained by stars in spiral galaxies that follow non-Keplerian orbits. A third chapter proposes that gravity attributed to dark matter is due to the sprinkling of black holes throughout galaxies, which is supported by LIGO/Virgo observations. Another chapter questions the assumptions of the Friedmann (FLRW) model, proposing a better method for handling astrophysical data. Additional chapters discuss cosmic ray propagation, axion decay, the cosmological scale factor, and the philosophical outlook of cosmologists when dealing with the questions of dark matter and dark energy.Books on Demand GmbH, Überseering 33, 22297 Hamburg 134 pp. Englisch.
