David MacKenzie directs this British drama in which a troubled teenager and his father bond in the unusual surroundings of a prison. 19-year-old Eric (Jack O'Connell) has had an extremely difficult childhood. Taken into care after the death of his mother and the sentencing of his father (Ben Mendelsohn), Eric's subsequent struggles with authority are highlighted by the fact that he has been 'starred up' from juvenile prison to the real thing, despite his tender years. Eric is happy with the outcome, though, as it gives him a chance to reconnect with his father and to demonstrate his toughness. However, with certain prison wardens not averse to using extreme violence to enforce order and protect others, Eric may have to tread carefully and pay attention to the calming words of his father if he is to make it out of the facility in one piece.

In our everyday activities we use material objects in different shapes and forms to solve various practical problems. We may use a knife to tighten a screw, turn an old washing machine drum into a fireplace, use the edge of a kitchen countertop to open a bottle, or place a hammer on the puncture patch glued to a bike's inner tube to exert pressure on the patch until the glue dries. How should we identify these objects? What functions do they have? If we want to understand the role which material objects play in our everyday activities, we need to move away from universal identifications of objects. This is because universal identifications are not sensitive to contextual differences and cannot describe how each individual user connects to their surrounding objects in an infinite variety of contexts. Problem Solving Technologies provides a user-friendly understanding of technological objects. This book develops a framework to characterise and categorize technological objects at the level of users' subjective experiences.

Safety or protective grounding is of vital importance for the protection of individuals from electric shock and structures and industrial concerns from potentially damaging lightning and electrostatic discharges. To many electrical engineers the notion of grounding is nebulous and safety grounding is quite often confused with neutral grounding of the power supply. The main objective of this book is to give the reader a better understanding of safety grounding, why it is needed, where it is needed, and what are the requirements which must be met in order to have an effective grounding system. The text as a whole serves to provide the reader with the necessary background for a better appreciation of the various National and International Standards concerned with safety grounding. This book gives the reader a good understanding of the fundamentals of safety grounding. It is a practical guide that provides a comprehensive coverage of all types of grounding requirements and is intended for students and practicing electrical engineers alike. Summarizes the physiological effects of current on the human body and the effect of current duration Gives the various methods of measuring soil resistivity and measuring the resistance to ground of an electrode or grounding system Reviews different types of ground electrodes and the effect of their geometry and numbers on the resistance to ground Presents the components of a ground system, methods of improving soil resistivity, the types of welds and joints, the criteria for determining conductor cross-sections, galvanic corrosion, and a survey of the different grounding practices used at substations and the different types of grounding systems used for the protection of consumers Deals with electrostatic and lightning hazards that can cause serious damage and the measures used to protect against such damage Throughout the text frequent reference is made to various National and International Standards and their requirements as compliance with these standards is highly advised Asser A. Zaky, Ph.D., FIET, F.Inst.P., FIEEE, is Emeritus Professor of Electrical Engineering at University of Alexandria, Egypt.

Haile Selassie I, the last emperor of Ethiopia, was as brilliant as he was formidable. An early proponent of African unity and independence who claimed to be a descendant of King Solomon, he fought with the Allies against the Axis powers during World War II and was a messianic figure for the Jamaican Rastafarians. But the final years of his empire saw turmoil and revolution, and he was ultimately overthrown and assassinated in a communist coup. Written by Asfa-Wossen Asserate, Haile Selassie s grandnephew, this is the first major biography on this final king of kings. Asserate, who spent his childhood and adolescence in Ethiopia before fleeing the revolution of 1974, knew Selassie personally and gained intimate insights into life at the imperial court. Introducing him as a reformer and an autocrat whose personal history with all of its upheavals, promises, and horrors reflects in many ways the history of the twentieth century itself, Asserate uses his own experiences and painstaking research in family and public archives to achieve a colorful and even-handed portrait of the emperor."

By describing and analysing the process which precedes decision-making in the Council of Ministers, an insider's view is presented in this book of the process of decision-making in the European Union. The main subject is the Permanent Representatives Committee, comprising Ambassadors of the Member States to the European Union, the Permanent Representatives. Coreper has the general responsibility for preparing the work of the Council.

The book is based on a legal thesis, which was published in Dutch at the end of 1993. For the English version the text has been revised and, where necessary, updated. The content, which is largely derived from practical experience, should provide a clearer picture of the current state of affairs of European integration in general, and the functioning of the European institutions in particular. To this extent the book serves the political objective of creating transparency in the decision-making of the European Union.

Audience:

All those working in the public services, international organizations, universities, liberal professions and economic life whose everyday work brings them into contact with aspects of the European Union and its institutions.

This comprehensive collection includes Asser’s Life of Alfred, extracts from The Anglo-Saxon Chronicle, and Alfred’s own writings, laws, and will.

Dieser Band enthalt fotomechanische Nachdrucke klassischer Arbeiten von Giuseppe Peano zur Analysis und zur mathematischen Logik aus den Jahren 1886 bis 1899, denen fur die Herausbildung der gegenwartigen Mathematik grosse Bedeutung zukommt. Im Nachwort berichtet der Herausgeber uber die Entstehungsgeschichte der abgedruckten Arbeiten, uber deren Stellung im Gesamtwerk Peanos und uber ihre Verflechtung mit der Entwicklung der Mathematik um die Jahrhundertwende. Fotos und Archivalien komplettieren das Buch. Aus den Besprechungen: "Die mathematische Behandlung der Grundlagen der Mathematik ... ist aus der Verbindung zweier verschiedener Forschungsrichtungen ... hervorgegangen. Einerseits das Werk der Meister der Analysis und der Geometrie, sofern sie ihre Axiome formulierten und systematisierten, und das Werk von Cantor und anderen uber Gebiete wie die Mengentheorie. Andererseits die symbolische Logik, die nach der notwendigen Entwicklungsperiode jetzt dank Peano und seinen Nachfolgern die technische Verwendbarkeit und logische Bundigkeit erreicht hat, die wesentlich sind fur ein mathematisches Hilfsmittel zur Behandlung dessen, was bisher die Grundlagen der Mathematik gebildet hat." "A.N. Whitehead, B. Russell"#1"

Nachdem seit dem Erscheinen des ersten Teiles del' "Einfiihrung in die Mathematische Logik" me hI' als 12 Jahre vergangen sind, bin ich nun mehr in del' Lage, den zweiten Teil vorzulegen. Entsprechend dem ur sprunglichen Plan enthalt er die wichtigsten Ergebnisse iiber die Pradi katenlogik del' ersten Stufe, die hie I' konsequent als Logik (einsortiger) elementarer Sprachen entwickelt wird. Ich behandle dabei sofort den Pradikatenkalkiil mit Identitat und Operationssymbolen; die zum Teil abweichenden Ergebnisse fiir den Pradikatenkalkiil ohne Identitat er scheinen als Resultate iiber Ausdrucke und Ausdrucksmengen, in denen das Gleichheitszeichen nicht vorkommt. Das hat den Vorteil, daB die Pradikatenlogik del' ersten Stufe sofort in einer solchen Allgemeinheit aufgebaut wird, wie man sie in del' mathematischen Grundlagenforschung (Metamathematik) beim Studium formalisierter elementarer Theorien in del' Regel auch tatsachlich benotigt. Wie auch im ersten Tei , geht es mil' VOl' allem um die Darstellung del' Wechselbeziehungen zwischen semantischen und syntaktischen Frage stellungen. Dabei habe ich mich insbesondere darum bemiiht, die Rolle des Modellbegriffs und des auf ihm basierenden Begriffs des logische'n Folgerns deutlich herauszuarbeiten. Ich halte den Folgerungsbegriff fiir den eigentlichen zentralen Begriff del' Logik, des sen formale (syntaktische) Erfassung das Hauptproblem del' mathematischen Logik darstellt. Dabei kommt diesel' formalen Erfassung in del' Pradikatenlogik wegen del' Nichtentscheidbarkeit d r Folgerungsrelation, die allerdings erst im dritten Teil bewiesen wird, grundsatzliche Bedeutung zu."
