quest fryer An unusually extended period (5 h) of polar cap auroral display on 3 August 1986 is examined.Auroras have been investigated using ground-based data as well as measurements from the IMP-8 spacecraft in interplanetary space and simultaneous observations from the polar-orbiting satellites Viking and DE-1 in the northern and southern hemisp

Predicting the volume of corrosion products (CP) and their distribution in here the steel rebar periphery will play an essential role in estimating the expansion stresses and, consequently, the behaviour of concrete in extreme environmental circumstances.In this respect, using the outcomes of performed laboratory studies, an attempt has been made t

Aiming at the vibrations of the multistage gear transmission system aroused by the gear meshing excitation, a novel active vibration control structure with built-in piezoelectric actuators (PZT) was established.The active control forces generated by the PZT were transmitted to the shafts through the additional supporting bearings.In addition, an ad

Optimal defibrillation timing guided by ventricular fibrillation (VF) waveform analysis would contribute to improved survival of out-of-hospital cardiac arrest (OHCA) patients by minimizing myocardial damage caused by futile defibrillation shocks here and minimizing interruptions to cardiopulmonary resuscitation.Recently, fuzzy entropy (FuzzyEn) ta

The present study explores synovex one grass the spatial pattern of selected soil sealing indicators in the province of Barcelona as a contribution to the debate on land consumption driven by urban growth in southern Europe.Four indicators of soil sealing (percentage of pervious land, per-capita sealed land, soil sealing intensity and diversity in
