It discusses the application of matrices, which has become an area of great importance in many scientific fields. The theory of row/column determinants of a partial solution to the system of two-sided quaternion matrix equations is analyzed. It introduces a matrix that has the exponential function as one of its eigenvectors and realizes that this matrix represents finite difference derivation of vectors on a partition. Mixing problems and the corresponding associated matrices have different structures that deserve to be studied in depth. Special compound magic squares will be considered. Finally, a new type of regular matrix generated by Fibonacci numbers is introduced and we shall investigate its various topological properties. 96 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Global wheat consumption in the 2016/2017 season is forecasted to reach a record high 736m tonnes, showing a growth of 25% in the last 15 years. This raises the question which outlets the wheat is going into, what the growth of these outlets is, which regions or countries have grown the most, and where do we see future potential. Strong competition of other feed grains like corn is expected to slow the growth of wheat used for feed in the next years, and in the future, companies involved in the grain supply chain and feeding industry will need to be flexible enough to continue to meet this fast-changing demand for feed grains. For feed producers, this means they need to be able to access supplies of different grains from different origins to allow for the cheapest composition of their feed, while grain suppliers need to be able to continuously best engage with global trading opportunities to originate grains in various regions and move them to demand regions as cost-effectively as possible. 250 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Tropical forests occupy only one-tenth of the world's land area but are home to more than half of the world's flora and fauna. They comprise extremely complex labyrinth of ecological interactions. The astounding richness and biodiversity of tropical forests are rapidly dwindling. There is a fear that the burgeoning human population and industrialization, where a majority of these tropical forests are found, may lead to the clearing or modification or may be a complete disappearance of the remaining tropical forests within few decades. This has severely altered the vital biogeochemical cycles of carbon, phosphorus, nitrogen, and so on and has led to the change in global climate and pristine natural ecosystems. Hence, there is an urgent need to protect, restore, conserve, and improve the forest resources before they are irrevocably lost. In this second edition of the book Tropical Forests, the chapters share the above issues and help in understanding, educating, and creating awareness on the role of 'tropical forests' for the very survival of mankind, climate change, and the diversity of biota across the globe. This book will be of great use and could be useful to students, scientists, ecologists, population and conservation biologists, and forest managers across the globe. 194 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Water is accepted as the most important source of life. It is assumed that life began in water and spread from there to the whole world. But water has been polluted anthropogenically since the beginning of the industrial revolution in the late 19th century.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth. 294 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Measurements in present experiments have dramatically advanced our understanding of ultrahigh-energy cosmic rays. The suppression of the flux at the highest energies is now confirmed without any doubt, and strong limits have been placed on the photon and neutrino components. There are indications for a small, large-scale anisotropy both below and above the energy of the angle and for a correlation on smaller angular scales at E > 5.5\*1019 eV. Around 3\*1018 eV, there is a distinct change of slope with energy, and the shower-to-shower variance decreases. Interpreted with the leading LHC-tuned shower models, this implies a gradual shift to a heavier composition, and a number of fundamentally different astrophysical model scenarios have been developed to describe this evolution. 172 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Evolving Strategies in Peritoneal Dialysis is intended as a concise compilation of articles designed to understand the basics of the current practice of the most cost-effective form of life support for patients with end-stage renal disease who require dialysis. Current strategies are understood best with a review of the historical development of catheter materials, solution packaging, and simplified machinery, which allow safe and effective nocturnal treatments. Quantitation of the efficacy of peritoneal dialysis is also reviewed because such calculations were also developed by the pioneers of nephrology to ensure adequacy of dialysis and daily fluid balance, which are responsible for the best chance for long-term patient survival. Comparison of methods for catheter placement is presented as well as the role that a dialysis center plays in the health and success of this form of end-stage renal disease patient care. The novel concept of assisted peritoneal dialysis for the infirm or institutionalized patients is probably the next direction needed to make available this treatment to many more patients than are currently eligible to receive it. This concept is explored in a separate chapter. Finally, professional dialysis staff must monthly assess individuals' nutritional status, bone health, and infection prevention and treatment to ensure the greatest functional status for these patients. This book concludes with a review of each of these topics to expand the mandatory monthly surveillance performed by dialysis centers for each patient who receives home peritoneal dialysis therapy. 114 pp. Englisch.
