This book is an introductory text for students of property law

The book provides undergraduate students with an extensive exposition of the general principles of South African Property Law. It is a sister title to Silberberg and Schoeman's The Law of Property which is written for postgraduate students and legal practitioners.

Real security law is where property law and credit law meet to regulate the rights that creditors have to property belonging to their debtors – either as agreed upon between the parties or as imposed by the law. Security rights facilitate affordable borrowing, investment in property and industry, and thus the promise of economic prosperity. Secured lenders are also empowered with stronger rights than other creditors and with more beneficial debt enforcement options. In our ever-changing economic and social context, a sophisticated system of law is necessary to maintain a fine balance between the rights of debtors, creditors, third parties and the general public – especially when things go wrong. Financial crises, rising consumer over-indebtedness and the fight against homelessness are but some important considerations that challenge this area of law.

Real Security Law covers all of the conventional forms of real security, such as the mortgage of land, the pledge of movables, general and special notarial bonds, security cessions, the landlord’s tacit hypothec and rights of retention. It also includes security mechanisms imposed by statutes, for example municipal charges, embargo powers, the instalment-agreement hypothec and statutory pledges.

The aim of this volume is to describe and analyse the current state of real security law in South Africa, starting with our common law foundation but with a particular focus on developments inspired by the Bill of Rights and other statutory and socio-economic changes in society. Therefore, the most recent developments in constitutional, statutory and case law are incorporated, and the aim is to strike a balance between legal theory, constitutional imperatives, commercial realities and the needs of practice.

Out-of-print for years, this highly sought-after volume, remains the most popular reference on inertial navigation systems analysis. Finally, this classic book is back in print and readily available only from Artech House. Authored by a pioneer in the field, this authoritative resource focuses on terrestrial navigation, but is also useful for air and sea applications. Packed with valuable, time-saving equations and models, the book helps engineers design optimal navigation systems by comparing the performance of the various types of system mechanizations. Although applications and technology have changed over the years, this book remains the best source for fundamental inertial navigation system knowledge, from notational conventions, reference frames, and geometry of the earth, to unified error analysis, self-alignment techniques, and the development of a system error model. This well-illustrated, timeless reference belongs on the shelf of every practicing engineer working in this area. It is suitable for electrical engineers working in the area of GPS and other navigation systems, as well as for graduate engineering students in related courses.

Transformative Property Law honours Professor AJ Van der Walt (1956-2016) - scholar, mentor, and teacher. As the first incumbent of the DST/NRF South African Research Chair in Property Law his primary research goal was to develop the theoretical foundations for the transformation of property law in post-apartheid South Africa. Covering topics that are at the forefront of global thinking on property law, Transformative Property Law consists of 20 essays by a combination of senior and young scholars from South Africa, the United States of America, the United Kingdom, Ireland, the Netherlands, Belgium, and Zimbabwe. The essays focus on the themes that Professor Van der Walt developed during the first 10 years of the research chair, namely: (a) the single system of law and subsidiarity principles; (b) the marginality principle; (c) the development of the common law of property; (d) constitutional property law; and (e) property theory. This volume also includes a list of all Professor Van der Walt's research outputs and a list of all the Masters and Doctoral students that he supervised during his career.

Klinefelter's syndrome occurs relatively frequently, being diagnosed for one in 600 male infants, yet it is probably very rare that it is recognized early enough to make effective treatment possible. Often the person afflicted does not go to a doctor until physical and emotional disturbances have developed on the ba sis of the syndrome. The appropriate therapy at the correct time can prevent many of these disturbances. In our andrology outpatient clinic we encountered Klinefelter's syndrome almost three decades ago in patients suffering from impotentia generandi. It was not until later that we dealt with it in our capacities as dematologists. It was observed at a rate too high to be coincidental among younger men suffer ing from ulcera crurum. On the other hand, we failed to see the condition during our work as con sultants in other specialities, especially internal medicine, although we re peatedly attempted to identify it. We should have encountered it at least occa sionally in our 10 years working in the Munich hospitals with their more than 4000 beds. It was this imbalance between the allegedly relative frequency of this condition and its rare detection which led us to plan a Klinefelter sympo sium. We soon determined, during a first search of the literature, that there was information in many more subject areas that we had expected or even guessed."
