Wirtschaftsmathematik
Dieses Lehrbuch richtet sich an alle, die Wirtschaftsmathematik im Grundstudium belegen müssen (aber vielleicht nicht immer möchten). Konzepte der Analysis und linearen Algebra im Rahmen einer einsemestrigen Vorlesung werden auf einer anwendungsorientierten Ebene erläutert. Im Vordergrund steht die Anwendung von Formeln und Konzepten, auf langwierige Herleitungen und Beweise wird verzichtet. Die Methoden werden schrittweise erklärt und mit detaillierten Beispielen und vielen Zwischenergebnissen vorgeführt. Daher sind sie gerade auch für diejenigen Studierenden besonders lesenswert und hilfreich, deren Kontakt mit Mathematik bereits einige Jahre zurückliegt.

Übungsbuch Wirtschaftsmathematik
Dieses Übungsbuch ergänzt das Lehrbuch Wirtschaftsmathematik - Einfach und verständlich und bietet ausführliche Lösungen mit detaillierten Ausführungen zu allen 109 Übungsaufgaben des Lehrbuchs, aber darüber hinaus mit über 60 zusätzlichen Aufgaben auch weiteres Übungsmaterial zur Vertiefung des Gelernten. Häufig hemmen fehlende Zwischenschritte das Verständnis bei der Bearbeitung des Übungsmaterials. Dieses Problem wird hier durch strukturierte und schrittweise Darstellung der Lösungswege ausgeschlossen. Viele Abbildungen veranschaulichen die Lösungen. Benötigte Lösungskonzepte werden wiederholt. Somit können diese auch von Lesern nachvollzogen werden, die sich die mathematische Theorie an anderer Stelle als dem zugrundeliegenden Lehrbuch erarbeitet haben und nun ergänzend praktische Anwendungsbeispiele wie Gewinnmaximierungsprobleme, Elastizitäten, Konsumenten- und Produzentenrente im Marktgleichgewicht suchen.

Wirtschaftsstatistik
Statistik gilt im wirtschaftswissenschaftlichen Studium oft als trockene Hürde voller abstrakter Formeln. Dieses Lehrbuch zeigt, dass es auch anders geht: Es setzt auf einen anwendungsorientierten Zugang, der Statistik als praktisches Werkzeug begreift - zur Datenanalyse, Entscheidungsfindung und zum Erkennen von Zusammenhängen. Statt theoretischer Herleitungen stehen konkrete Rechenwege im Mittelpunkt, erklärt wie in einem Rezept: Was wird gebraucht, wie wird vorgegangen, was kommt dabei heraus? Formeln werden Schritt für Schritt eingesetzt und anhand nachvollziehbarer Beispiele aus Wirtschaft, Nachhaltigkeit, Tourismus und Sport erklärt - ganz ohne Kugeln und Urnen. Jedes Kapitel enthält zahlreiche Übungsaufgaben mit ausführlich kommentierten Lösungen, die jeden Zwischenschritt transparent machen. Die behandelten Themen decken alle Grundlagen ab, die in ein- oder zweisemestrigen Statistikmodulen typischerweise verlangt werden: von beschreibender Statistik über Wahrscheinlichkeitsrechnung und Verteilungen bis hin zu Schätzverfahren, Hypothesentests und Regressionsanalysen.

Surface Chemistry of Froth Flotation
th The technology of froth flotation, invented in the early 20 century was first used for the concentration of sulfide minerals. Since then it has been applied for the processing of many nonsulfide ores as weIl, including oxides, carbonates, silicates, soluble minerals like halite and sylvite and energy minerals like coal and bitumen. In recent years it has been used for several nonrnineral applications, such as waste water treatment, deinking of paper for recycling and resource recovery from industrial wastes he technology continues to grow with new applications reported every year. Flotation is based on chemical phenomena occurring at the interfaces, solid/water and air/water. Surface Chemistry principles have played a significant role in the development of flotation technology. Knowledge of aqueous solution chemistry and electrochemistry has added to our understanding of the reactions in flotation systems. Professor Jan Leja's book has weIl served researchers and students as they tried to understand the chemistry of flotation, and it is a significant contribution to the advancement of knowledge. However, since the book was first published, new research techniques and ever growing information have made an update necessary. The revised edition compiled by Dr. S. R. Rao has brought together fundamental aspects of the chemistry of flotation and how they apply to practical systems. It should serve all who are working in the area of flotation and interested in exploring new applications of flotation technology.

Flotsam
‘By turns beguiling and unsettling, Flotsam examines grief and loss through the eyes of an extraordinary child’ Rachel SeiffertTrine and her mother live in a cottage on the German coast. The mudflats that surround them disappear and reappear with the North Sea tides. The family leads a lonely existence, but each person has adapted in their own way. Anna roams the beaches collecting flotsam and jetsam to make art, while Trine loves playing on a wartime shipwreck. That is, until she loses her brother.In her taut style, Meike Ziervogel tells a coming-of-age story from 1950s Germany – a place still haunted by war. A place where people pretend not to notice the ghosts.

Lives of Galba and Otho
Plutarch's "Lives of Galba and Otho" constitute the earliest surviving history of the shocking events that shook the Roman Empire in AD 68 and 69 - the rebellions against Nero, his betrayal and suicide, and Galba's disastrous reign, which ended in his murder. No other source preserves such a coherent account of the extraordinary events of 68, and for 69 Plutarch's "Lives" are comparable with Tacitus' "Histories". As well as including a translation, this useful companion explains the background, and provides a commentary that makes serious use of the numismatic evidence.

Klotho
Klotho is the latest edition of a series first published in 1943 on Vitamins and Hormones and the longest-running serial published by Academic Press. It provides up-to-date information on vitamin and hormone research spanning data from molecular biology to the clinic, with volumes focusing on a single molecule or on a disease that is related to vitamins or hormones that are interpreted broadly so that related substances, such as transmitters, cytokines, growth factors, and others can be reviewed.

Flotsametrics and the Floating World
Curtis Ebbesmeyer is no ordinary scientist. He's been a consulting oceanographer for multinational firms and a lead scientist on international research expeditions, but he's never held a conventional academic appointment. He seized the world's imagination as no ordinary scientist could when he and his worldwide network of beachcomber volunteers traced the ocean's currents using thousands of sneakers and plastic bath toys spilled from storm-tossed freighters. Now, for the first time, Ebbesmeyer tells the story of his lifelong struggle to solve the sea's mysteries, and shares his most surprising discoveries. He recounts how flotsam has changed the course of history-leading Viking mariners to safe harbours, Columbus to the New World, and Japan to open up to the West - and how it may even have made the origin of life possible. He explores the vast floating garbage patches and waste-heaped junk beaches that collect the flotsam and jetsam of industrial society. Finally, he reveals the music-like mathematical order in oceanic gyres and the threats that global warming and disintegrating plastic waste pose to the seas ...and to us.

Secret Flotillas
This authoritative publication by the official historian, the late Sir Brooks Richards, vividly describes and analyses the clandestine naval operations that took place during World War II. The account has been made possible through Sir Brooks' access to closed government archives, combined with his own wartime experiences and the recollections of many of those involved.In addition to operations off French North Africa this second volume also includes descriptions of operations in the Adriatic around Italy. More than half of the 390 operations in Italian and adjacent waters were carried out by Italian vessels with Italian crews. It was a contribution to the Allied war effort which ought not to be forgotten.

Dissolved Air Flotation
This book provides an overview of the dissolved air flotation clarification technology. It brings together the three strands of knowledge and experience accumulated in this field - the analysis of the main phenomena involved and the interactions between them, the equipment for its implementation and its main applications in water treatment. The author draws attention to the design and operation of the different equipment used in practice, their advantages, and disadvantages in the different fields of application of this technology.The book is intended for:•Engineers and technicians working on the design of equipment and its integration into the overall water treatment plant as well as in the operation of flotation plants.•Consultants and engineering offices, hoping that it will help them to make the most appropriate choices regarding the applications of this process, as well as in the equipment selections.•Wastewater treatment plants operators, in the hope that it will help them to optimise the operation of their plants and improve their understanding and analysis of some problems they may encounter.•Purchasers and contractors, who have to make sometime difficult choices for reducing costs and, at the same time, ensure and guarantee the long-term performance and reliability of the plant.The book is oriented towards the practical side of implementing the technology. It contains a lot of information about the equipment (much more than in all other available publications on the same subject) as well as practical comments and recommendations that are very rarely found in this kind of book, written mostly by researchers. It will appeal to specialists who are comfortable with water chemistry, but it may also be of interest to water professionals who are more interested in the equipment, design and operation of water treatment plants.

Flotsam
A bright, science-minded boy goes to the beach equipped to collect and examine flotsam-anything floating that has been washed ashore. Bottles, lost toys, small objects of every description are among his usual finds. But there's no way he could have prepared for one particular discovery: a barnacle-encrusted underwater camera, with its own secrets to share . . . and to keep.
