Outdoor substations placed in coastal areas are affected by saline environments. In the technical literature it is found extensive information regarding insulations problems in presence of saline environments [1]. The accumulation of salts and other contaminants promotes the onset of partial discharges on the devices subjected to very high voltages. Insulators are also affected by this phenomen...

Running title: Sharp wave activity in Cx36 knock out mice. ABSTRACT Bath application of kainate (100-300 nM) induced a persistent gamma frequency (30-80 Hz) oscillation that could be recorded in stratum (s) radiatum of the CA3 region in vitro. We have previously described that in knockout mice lacking the gap junction protein connexin 36, (Cx36KO), gamma frequency oscillations are reduced but s...

Bath application of kainate (100-300 nM) induced a persistent gamma-frequency (30-80 Hz) oscillation that could be recorded in stratum radiatum of the CA3 region in vitro. We have previously described that in knockout mice lacking the gap junction protein connexin 36 (Cx36KO), gamma-frequency oscillations are reduced but still present. We now demonstrate that in the Cx36KO mice, but not in wild...

In this paper a method for extracting Partial Discharge (PD) signals is introduced, which is implemented for evaluating electrical measured partial discharges on a 66 kV / 25 MVA fully interleaved winding of a power transformer. Applying wavelet transform to a signal produces a wavelet detail coefficient distribution throughout the time-scale, which depends on the mother wavelet chosen. This me...

The aim of this article is to create a novel filtering algorithm for the emitted electromagnetic signals corona discharges, using special time-domain features continuous wavelet transform. first part therefore focuses on examination these find characteristic that are compatible with second utilizes and validate algorithm. This an important step toward creating accurate three-dimensional partial...

Partial discharge measurement is an important means of assessing the condition and integrity of insulation systems in high voltage power apparatus. Commercially available partial discharge detectors display them as patterns by an elliptic time base. Over the years, experts have been interpreting and recognising the nature and cause of partial discharges by studying these patterns. A way to auto...

A cerebral network comprising precuneus, medial frontal, and temporoparietal cortices is less active both during goal-directed behavior and states of reduced consciousness than during conscious rest. We tested the hypothesis that the interictal epileptic discharges affect activity in these brain regions in patients with temporal lobe epilepsy who have complex partial seizures. At the group leve...

OBJECTIVE To test the hypothesis that treatment with cefepime hydrochloride leads to higher incidence of periodic epileptiform discharges compared with treatment with other β-lactams. DESIGN Data from hospital pharmacy databases of patients treated with cefepime or meropenem during a 42-month period (from January 1, 2007, through June 30, 2010) were retrospectively crossed with data from the ...

Perfusion of rat brain slices with low millimole CsCl elicits slow oscillations of </=1 Hz in hippocampal CA1 pyramidal neurons. These oscillations are GABAA receptor-mediated hyperpolarizations that permit a coherent fire-pause pattern in a population of CA1 neurons. They can persist without the activation of ionotropic glutamate receptors but require adenosine-dependent inhibition of glutamat...
