        Formulation Plausibility Check

        In accordance with § 7 German Ordinanceon the Operation of a Pharmacy

        by Dr. Andreas S. Ziegler

        The Ordinance on the Operation of a Pharmacy states that a plausibility check must be undertaken for each new formulation. The tabular compilations of this book help pharmacists to complete this task quickly and reliably. All the information required for the check is clearly laid out and easy to find. New in the 6th edition: Many new active substance – ointment base combinations with demonstrated compatibility | more than 50 new ointment bases | 30 new active substances Bonus: The information about standard doses for paediatric dermatology enables pharmacists to also prepare paediatric formulations. | References to the Ziegler Rezepturbibliothek® (Ziegler Formulation Library), where completely formulated manufacturing instructions for the named active substance – ointment base – combinations can be found. This makes it even easier to supply patients with tested standard preparations. The set includes 50-sheet pads of the complementary form Plausibility Check. The form makes documentation easier and enables rapid and reliable navigation through the tables. This allows both the prescriber’s treatment concept and also possible incompatibilities to be checked in less than no time.

        Entomopathogenic nematodes (EPNs) are biocontrol agents that are used to control a wide variety of insect pests within agriculture and forestry. In addition to their use as bio-pesticides, EPNs have a fascinating biology and are thus considered model organisms in ecology, symbiosis and pathogenesis. This book presents basic knowledge and diverse applications to illustrate how EPNs play an important role as potent biocontrol solutions. It describes: Fundamental concepts such as biology, taxonomy, symbiosis genomics and behavioural ecology. Aspects of commercialization, including mass production, formulation, safety and regulation, and marketing. Diverse cropping systems e.g. maize, wheat and grains, citrus, orchard systems, berries, vine crops, vegetables and turf. Other applications including urban, nursery, forestry, greenhouse, veterinary and medical. Ecological considerations and applications in conservation biocontrol. This book is a must have for all pest management professionals including those practicing integrated pest management strategies.

        Spy without a Cause

        by Neil Thomas

        A fast-paced story of an ordinary man who becomes accidentally involved with villains in business and government in Hong Kong, Manila and Singapore, this is Neil Thomas’ third gripping novel.​ With a background of intrigue, corruption and tax avoidance, this intricate novel is set against events in the early 1980s in Britain’s Hong Kong, the Manila of Marcos and Lee Kuan Yew’s Singapore. A young publisher travelling through the East on business is confronted with personal greed, kleptocracy, espionage and murder as matters move, Eric Ambler style, out of his control.  In Hong Kong, still British at that time, he first meets Jimmy Chan – a ruthless operator he is supposed to do business with – whose tentacles reach far and wide and prove tricky to escape. A side trip to the Philippines affords him no respite and his contact with the corruption of the Marcos regime only serves to make life more unpleasant as developments take a sinister turn. In this fast-paced story, an ordinary man, confronted with shady and unsavoury characters, becomes accidentally involved with villains in business and government in three different locations who operate according to a different moral code from his own.

        Agents of European overseas empires

        Private colonisers, 1450-1800

        by Elodie Peyrol-Kleiber, L. H. Roper, Bertrand Van Ruymbeke, Agnès Delahaye

        Agents of European overseas empires involves contributors who specialise on often overlooked aspects of imperial endeavour: 'private' European interests, companies, merchants or courtiers, who conducted their own activities both with and without the benediction of polities. The chapters adopt intra- as well as inter-imperial perspectives and transport the reader to colonial America, the West Indies, the Cape of Good Hope, Batavia, or Ceylon, through the Dutch, English, French and Spanish empires. Agents of European overseas empires offers crucial insight on how these actors acquired profits and power and, in turn, laid the platforms for European global empires.

        by Kathrin Bielfedt, Jürgen Bürger, Ben Macintyre

        Ursula Kuczynski wuchs in einer großbürgerlichen jüdischen Familie in Berlin-Schlachtensee auf. In New York bewegte sie sich in den besten Kreisen. Sie hatte Affären, war mehrmals verheiratet und hatte Kinder. Doch ihre große, wahre Liebe galt dem Kommunismus. Ihm diente sie als Saboteurin, Bombenbauerin und Geheimagentin. Ihr Codename: »Agent Sonja«. 1923, Ursula ist gerade einmal sechzehn Jahre alt, wird sie bei einer 1.-Mai-Demonstration von einem Polizisten niedergeknüppelt. Es ist nur ein Grund mehr für sie, der Kommunistischen Partei beizutreten und deren Ideen in die Welt hinauszutragen. Mit Anfang zwanzig begleitet sie ihren ersten Ehemann nach Shanghai, wo sie Richard Sorge kennenlernt. Der Meisterspion wirbt sie für den russischen Geheimdienst an und sorgt dafür, dass sie in Moskau eine Ausbildung zur Agentin absolviert. Von dort aus geht es für sie in die Mandschurei und anschließend in die Schweiz, wo sie ein Bombenattentat auf Hitler plant. In den 50er Jahren wird sie in der DDR unter dem Namen Ruth Werner zur Erfolgsautorin.Den größten Dienst erweist sie der Sowjetunion aber, indem sie zwischen 1943 und 1949 Informationen über das britische Atomprogramm an Moskau weitergibt – eine der gefährlichsten Spionageaktionen des 20.

        Consumerism and the Co-operative movement in modern British history

        Taking stock

        by Lawrence Black, Nicole Robertson

        Despite the abundance and quality of recent historical writing on consumerism, it cannot be said that the modern Co-operative movement (Co-op) has been well served. It has also been by-passed in studies that locate Britons' identity in their consumption. The reasons for this can be found in the widely perceived decline of the Co-op since the 1950s, but also in various historiographical agendas that have resulted in its relative invisibility in modern British history. This book, by demonstrating the variety of broader issues that can be addressed through the Co-op and the vibrancy of new historical research into consumption, seeks to remedy this. Taking stock, both of the Co-op in a broader context and of new approaches to the history of consumption, combines the work of leading authorities on the Co-op with recent scholarly research. It explores the Co-op's distinctive interface between everyday issues and grander idealistic concerns. The chapters intersect to examine a broad range of themes, notably: the politics of consumerism including consumer protection, ethical and fair trading and alternatives to corporate commerce; design and advertising; the Co-op's relations with other components of the labour movement; and its ideology, image and memory. The collection looks at the Co-operative movement locally (through specific case studies), nationally and also in comparison to the European movement. This collection will appeal to academics, researchers, teachers and students of the economic, cultural and political history of twentieth-century Britain. It will also be of interest to academics and students of business studies, and co-operative members themselves. ;
