Written for geodesists using computers of modest capacity, the book reviews the latest development in geodetic computation techniques. The aim is to take stock of available data (datums, ellipsoids, units etc.), to focus on applications and to illuminate spatial developments. Topics cover datums and reference systems, geodetic arc distances, different projections and coordinate systems. The material has been specially chosen and covers the practical aspect of geodesy, including the demonstration of global examples. Stressing the how-to-do approach, the book is of interest to students in geodesy, GIS consultants, hydrographers and land surveyors.

Surveying a Century Ago As it was based on the principles of geometry and trigonometry, surveying may be may be looked upon as a branch of practical mathematics. Hence, it was necessary that land surveyors and hydrographers should have a fair general knowledge, not only of these subjects, but also of all the subjects comprised by the term mathemat ics. In addition, the knowledge of mathematics required in ordinary chain surveying and levelling was not very extensive but in geodetical work, the highest mathematical ability and great organising power were required for a proper conception and supervision of the operations (Threlfall, 1940). Only small area of a few hundred square kilometres can be accurately mapped and surveyed without a frame work, since no difficulty is encountered because of Earth-curvature. In the past, especially in hydrography due to the type of work, surveying was carried out on the principles of ordinary practice, but in a very rough man ner, rapidity of execution being of paramount importance, the permissible error was sometimes large. The relative positions of the main surface features were obtained by aid of portable instruments, such as sextants and lead lines, tide poles, and logships. Sketching, just like military surveying was often filling in the smaller detail. In contrary, survey works done by the national mapping agencies (NMAs) were of a higher-level, and comprised the delimitation of boundaries as well as topographical surveys.

"Affective Health and Masculinities in South Africa explores how different masculinities modulate substance use, interpersonal violence, suicidality, and AIDS as well as recovery cross-culturally. With a focus on three male protagonists living in very distinct urban areas of Cape Town, this comparative ethnography shows that men's struggles to become invulnerable increase vulnerability. Through an analysis of masculinities as social assemblages, the study shows how affective health problems are tied to modern individualism rather than African 'tradition' that has become a clichâe in Eurocentric gender studies. Affective health is conceptualized as a balancing act between autonomy and connectivity that after colonialism and apartheid has become compromised through the imperative of self-reliance. This book provides a rare perspective on young men's vulnerability in everyday life that may affect the reader and spark discussion about how masculinities in relationships shape physical and psychological health. Moreover, it shows how men change in the face of distress in ways that may look different than global health and gender transformative approaches envision. Thick descriptions of actual events over the life course make the study accessible to both graduate and undergraduate students in the social sciences. Contributing to current debates on mental health and masculinity, the volume will be of interest to scholars from a number of disciplines including anthropology, gender studies, African studies, psychology and global health"--

Due to steadily improving experimental accuracy, relativistic concepts – based on Einstein’s theory of Special and General Relativity – are playing an increasingly important role in modern geodesy. This book offers an introduction to the emerging field of relativistic geodesy, and covers topics ranging from the description of clocks and test bodies, to time and frequency measurements, to current and future observations. Emphasis is placed on geodetically relevant definitions and fundamental methods in the context of Einstein’s theory (e.g. the role of observers, use of clocks, definition of reference systems and the geoid, use of relativistic approximation schemes). Further, the applications discussed range from chronometric and gradiometric determinations of the gravitational field, to the latest (satellite) experiments. The impact of choices made at a fundamental theoretical level on the interpretation of measurements and the planning of future experiments is also highlighted. Providing an up-to-the-minute status report on the respective topics discussed, the book will not only benefit experts, but will also serve as a guide for students with a background in either geodesy or gravitational physics who are interested in entering and exploring this emerging field.

The objective of these volumes is to combine solid practical information with sufficient background material to ensure that the novice can understand how a technique works, what it achieves, and how to make modifications to suit personal requirements. The second volume details procedures for isolating and studying individual genes (preparation and screening of libraries, polymerase chain reactions, DNA sequencing and studying gene expression).
