Definition: These may take the form of ideas, mental images, or impulses to act, which are nearly always distressing to the subject. Sometimes the ideas are an indecisive, endless consideration of alternatives, associated with an inability to make trivial but necessary decisions in day-to-day living. The relationship between obsessional ruminations and depression is particularly close and a diagnosis of obsessive-compulsive disorder should be preferred only if ruminations arise or persist in the absence of a depressive episode.

Definition: Personality disorder characterized by a definite tendency to act impulsively and without consideration of the consequences; the mood is unpredictable and capricious. There is a liability to outbursts of emotion and an incapacity to control the behavioural explosions. There is a tendency to quarrelsome behaviour and to conflicts with others, especially when impulsive acts are thwarted or censored. Two types may be distinguished: the impulsive type, characterized predominantly by emotional instability and lack of impulse control, and the borderline type, characterized in addition by disturbances in self-image, aims, and intern ...[+++]al preferences, by chronic feelings of emptiness, by intense and unstable interpersonal relationships, and by a tendency to self-destructive behaviour, including suicide gestures and attempts. | Personality (disorder):aggressive | borderline | explosive

Definition: Reliance on some non-living object as a stimulus for sexual arousal and sexual gratification. Many fetishes are extensions of the human body, such as articles of clothing or footwear. Other common examples are characterized by some particular texture such as rubber, plastic or leather. Fetish objects vary in their importance to the individual. In some cases they simply serve to enhance sexual excitement achieved in ordinary ways (e.g. having the partner wear a particular garment).

The pulse trawl gear consists of a number of electrodes, attached to the gear in the towing direction, that emit short electric pulses.

where Vis the peak electron energy in million electron volts and Q is the total accelerated charge in coulombs if the accelerator beam pulse duration is less than or equal to 1 µs, if the acceleration beam pulse duration is greater than 1µs, Q is the maximum accelerated charge in 1 µs [Q equals the integral of i with respect to t, over the lesser of 1 µs or the time duration of the beam pulse (Q =ƒidt), where i is beam current in amperes and t is the time in seconds]; or

(a) for the purpose of determining susceptibility to conducted interference, the register and ancillary equipment that operate from the main power supply are tested with test spikes superimposed on the supply, each having the wave-form shown in the schedule, with a pulse repetition rate of 10 spikes per second for a period of 10 minutes; and

In this context a number of hearings took place with petitioners representing the rights of blind persons who were fighting for the right to have access to reading material under the terms of the UN WIPO Convention which was under negotiation throughout 2013, and which was following pressure from the European Parliament on the Commission and Member States, eventually concluded and signed.
