This paper compares two reduction principles in child language, Tense/Agreement Omission (Schütze 1997, Wexler 1998) and Root Peripheral Truncation (Rizzi 1994, 2001). The paper argues that the empirical content of these proposals as well as their partial overlap follows from an inherent hierarchy of acquisition steps of the kind predicted in Jakobson (1942). The empirical support for this rein...

The pressure drop of refrigerant R-134a flow boiling inside a horizontal tube has been investigated experimentally. The test set-up which was used in this investigation is a well instrumented vapor compression refrigeration system. These instruments are thermocouples, flow meter, pressure gauges and the pressure drop measuring apparatus. This system consisted of three electrically heated evapor...

The force, f, required to slide a drop past a surface is often considered in the literature as linear with the drop width, w, so that f/w = const. Furthermore, according to the Dussan equation for the case that the advancing and receding contact angles are constant with drop size, one can further simplify the above proportionality to f/V(1/3) = const where V is the drop volume. We show, however...

PURPOSE The effectiveness of VNS was evaluated in thirty-nine encephalopatic patients with drug-resistant epilepsy characterized by multiple seizures and drop attacks. Twenty-five patients were affected by severe epilepsy with multiple independent spike foci (SE-MISF) and fourteen patients by Lennox-Gastaut syndrome (LGS). METHOD Changes in seizure frequency, cognition, adaptive behaviour and...
