The Van Speijk class frigates were equipped with Dutch electronics/sensors. The British Leander design was chosen to enable rapid construction to replace elderly escorts for ASW duties and NATO patrol. The ships were thoroughly modernised in the late 1970s. Between 1986-1990 all six were transferred to the Indonesian Navy.

Both Tromp-class frigates entered service in 1975/76. Their primary task was area air defence. They acted as flagships for the COMNLTG (Commander Netherlands Task Group). Because of their large radome (wich housed a 3D radar antenna) the ships had the nickname "Kojak" after the bald-headed actor in the famous action crime tv-series.

The aim of this volume is to revitalise the debate about the concepts of time implicit in the study of aging. The many problems related to aging and the aged put an enormous pressure on the gerontological community to come up with practical applications and solutions. In considering research findings, we must keep in mind the basic assumptions that shape and influence even the most obvious statements about aging. In this multidisciplinary volume, the contributors take on the important task of exploring real issues concerning temporal concepts and approaches to aging; and the concepts of time that are used in thinking about aging determine to a large extent the way aging is approached. Most studies of aging still use a chronological approach to define populations for research purposes (that is, to determine which "aged" should be studied) and to establish how people's characteristics (social, economic, health and so forth) change as a function of age. This approach may lead to an accumulation of data, but does not in itself lead to explanatory knowledge. The step from chronological time to chronological age should be taken cautiously if we want to consider aging processes seriously, especially because chronological age is widely used in contemporary societies as a basis for regulating all kinds of processes, with many consequences for individuals. The arguments presented here do not deny the finitude of human life, nor do they deny that "aging" can be observed in any individual if we compare the characteristics of that person over a relatively long period. The question is how to approach these themes to get a better understanding. To achieve this, we need to understand the specific significance and relativity of chronological time and uncover unfounded deductions about time in relation to aging. This book will be of interested to students and professors of the social sciences, humanities and aging, including the methodology of aging studies; professionals working in the field of aging, including sociologists, psychologists and biologists.

In the last century, developments in mathematics, philosophy, physics, computer science, economics and linguistics have proven important for the development of logic. There has been an influx of new ideas, concerns, and logical systems reflecting a great variety of reasoning tasks in the sciences. This book embodies the multi-dimensional interplay between logic and science, presenting contributions from the world's leading scholars on new trends and possible developments for research.

In the last century developments in mathematics, philosophy, physics, computer science, economics and linguistics have proven important for the development of logic. There has been an influx of new ideas, concerns, and logical systems reflecting a great variety of reasoning tasks in the sciences. This volume reflects the multi-dimensional nature of the interplay between logic and science. It presents contributions from the world's leading scholars under the following headings: - Proof, Knowledge and Computation;- Truth Values beyond Bivalence;- Category-Theoretic Structures;- Independence, Evaluation Games, and Imperfect Information;- Dialogue and Pragmatics

To counter a growing threat of Soviet submarines and aircraft shortly after WWII, the Royal Netherlands Navy ordered new ships. Classified as ASW destroyer (onderzeebootjager), but so close to contemporary destroyers in terms of specifications. Still suffering from the havoc of war the national industry managed to design and construct these ships in two classes. Drenthe was of the more capable Type 47B series.
