This is a comprehensive work summarizing the current state of knowledge of the biology of the hard ticks (Acari: Ixodidae) of Southern Africa (South Africa, Namibia, Botswana, Swaziland, Lesotho and Maputo Province, Mozambique). It provides an overview of the history of tick research in Southern Africa and the evolution of our knowledge of the ticks’ distribution and biology, as well as the methods used to determine tick distribution, abundance and host preference. The morphologies of most of the tick species known to occur in Southern Africa are described and illustrated, and their distributions are described and mapped in relation to the biomes of the region. The known hosts for each tick species are listed, and the tick’s host preferences are discussed. Information on most species life cycle in the laboratory and the field, and their seasonal occurrence, is summarized. The diseases of animals and humans transmitted or caused by each tick species are summarized in relation to tick ecology. Aspects of the biology of the major hosts relevant to tick infestations are described, and extensive tick/host and host/tick lists are provided for each country
Heat Kernel on Lie Groups and Maximally Symmetric Spaces
This monograph studies the heat kernel for the spin-tensor Laplacians on Lie groups and maximally symmetric spaces. It introduces many original ideas, methods, and tools developed by the author and provides a list of all known exact results in explicit form – and derives them – for the heat kernel on spheres and hyperbolic spaces. Part I considers the geometry of simple Lie groups and maximally symmetric spaces in detail, and Part II discusses the calculation of the heat kernel for scalar, spinor, and generic Laplacians on spheres and hyperbolic spaces in various dimensions. This text will be a valuable resource for researchers and graduate students working in various areas of mathematics – such as global analysis, spectral geometry, stochastic processes, and financial mathematics – as well in areas of mathematical and theoretical physics – including quantum field theory, quantum gravity, string theory, and statistical physics.

Originating at the beginning of the eighteenth century, Windsor chairs have been produced as disposable garden and verandah chairs and as finely carved royal furniture and, whether made by hand or machine, their basic, simple country lines have made them very collectable. To many people, the wide range of Windsor chairs is completely unknown, linking the name as they do with only the most popular type, the wheelback Windsor chair. This book attempts to introduce these to the reader and to point out some of the basic characteristics which help in the naming and dating of Windsor chairs.

This book has been designed to summarize current, essential information for every one of the world’s 700+ hard tick species. Under each species name, we will cite the original description, followed by information on type depositories, known stages, distribution (by zoogeographic region and ecoregion), hosts, and human infestation (if any). Each species account will also include a list of salient references and, where necessary, remarks on systematic status. We envision eight chapters: six devoted to the major ixodid tick genera (Amblyomma, Dermacentor, Haemaphysalis, Hyalomma, Ixodes, Rhipicephalus), one covering eight minor genera (including two that are fossil), and a concluding summary chapter. There will be two tables on host associations and zoogeography in each major genus chapter, as well as five tables in the summary chapter, for a total of 17 tables. No similar synopsis of the world’s hard tick species exists in any language.?

In the Name of Oil

In the Name of Oil

Ivan L G Pearson

LIVERPOOL UNIVERSITY PRESS

Traditional historiographies of the Cold War in the Middle East contend that the Suez Crisis marked the demise of Britain's political influence in the region. By contrast, using recently declassified documents, Ivan Pearson argues that although the Suez Crisis was cataclysmic on many dimensions, it did not mark a precipitous turning point in Britain's ability to affect events in the Middle East decisively. Although Suez wholly undermined British prestige, and revealed severe shortcomings in its military capabilities, these losses were considerably offset by the increasing ability of British policy-makers to influence the United States a country with an emerging presence in the region. In several critical instances during the 1950s both before and after the Crisis British policy-makers were successful in shaping events in the Middle East through a concerted lobbying effort that swayed the course of policy action pursued by the US. In the Name of Oil documents the frequent bureaucratic infighting between the Administration, State Department, and CIA on the American side, as well as the way in which the British took advantage of the blurred line between communism and Arab nationalism in the Middle East to mislead the US into pursuing policies that would protect the cheap oil supplied by British-owned oil giants such as the Anglo-Iranian Oil Company and the Iraq Petroleum Company. The narrative explains the crucial role of local actors, and the tangled web of interests and circumstances: Western-backed coups, counter-coups, political intimidation, rigged elections, misinformation, and bribery. Barely a decade after the end of World War II, the war's liberal democratic victors were engaged in dubious acts in the name of protecting Europe's access to cheap Middle Eastern Oil.

Reign of Terror: Ivan IV

Ruslan Grigor'evitch Skrynnikov unfolds the drama of terror under Ivan the Terrible and his oprichnina. He uses new kinds of evidence paying close attention to primary sources. The conflicts between Ivan and the gentry, the crushing of Novgorod autonomy, the ways in which Ivan interpreted his authority and sought to create an alternative base of power in a loyal body of henchmen-followers known as the oprichnina, the alienation of different groups in society from the government, the impoverishment and weakening of whole regions leading to the Time of Troubles are among the themes that Skrynnikov develops. The details of Ivan’s confrontations with those he perceived as opponents, the forms of execution he inflicted on his enemies, the atmosphere of peril and suspicion that he created justify the description of his reign as one of terror, relevant of course to later periods of history with obvious echoes of the Stalinist period.

Uno de los mayores xitos de los ltimos a os ha sido el avance alcanzado en la atenci n al reci n nacido pret rmino, sin embargo, la prematurez contin a siendo el principal problema de la neonatolog a contempor nea. Dentro de los prematuros, reviste gran importancia, por su morbilidad, el grupo de neonatos ventilados. La ventilaci n ha sido una de las tecnolog as del cuidado intensivo que m s ha contribuido al descenso de la mortalidad infantil, sobre todo en neonatos de muy bajo peso. Sin embargo, las alteraciones de neurodesarrollo a largo plazo no disminuyen. Una posible explicaci n es que las pr cticas ventilatorias tan tiles cuando se utilizan en forma proporcionada y adecuada pueden da ar el cerebro en desarrollo al usarlas excesivamente (ej. hipocarbia, hiperoxia). Objetivo: Demostrar neurodesarrollo anormal en reci n nacidos prematuros con peso menor a 1500 gramos que presentaron alteraciones en los niveles de CO y O por la ventilaci n.
