Straight Wire

A practical and well-illustrated guide to microbiological, haematological, and blood transfusion techniques.

Hoping to simplify matters for engineers overwhelmed by inductance calculations, the author brings together an invaluable collection of formulas and tables. For virtually every type of inductor, Dr. Grover provides a single simple formula, together with tables from which essential numerical factors may be interpolated. Starting with a survey of general principles, the text explains circuits with straight filaments; parallel elements of equal length; mutual inductance of unequal parallel filaments and filaments inclined at an angle to each other; and inductance of single-layer coils on rectangular winding forms. Additional topics include the mutual inductance of coaxial circular filaments and of coaxial circular coils; self-inductance of circular coils of rectangular cross section; mutual inductance of solenoid and a coaxial circular filament and coaxial single-layer coils; single-layer coils on cylindrical winding forms; and special types of single-layer coil. 1946 ed.

Beneath the surface of Aardenburg, a small town in the south-western part of the Netherlands, lie the remains of a Roman settlement that is presumed to have been named Rodanum. Extensive archaeological excavations from the late 1950s to the late 1980s revealed that the settlement was similar in size or even larger than the modern town. Its centre was formed by a large castellum-type fortification wall that enclosed several large stone buildings. The settlement was connected to the sea by a natural watercourse that defined its economic and logistical importance in the region. Rodanum's military function was to secure the regional coast against attacks by Germanic tribes via the North Sea, which occurred around AD 175. It continued to be inhabited until the late third century or the beginning of the fourth century, after which the settlement was deserted until the early Middle Ages. The first part of this study provides an overview of Aardenburg during the Roman period, in which its economic and military functions within the region are explored. In particular, the military and civilian character of the town is discussed. The second part contains a study of the metal objects and aims to present significant additional information. This part concludes with a critical review of the current state of research at this site.

The main concern of this book is to present the methods used to calculate the most important rope quantities as well as to explain how they are applied by means of a large number of calculations as examples. The book, based on the most important chapters of the German book DRAHTSEILE, has been kept up to date and takes into account the most recent developments.
