To repair corroded subsea pipelines, composite fiber-reinforced polymer (CFRP) patches are often attached to the defected area. The aim of this paper is present a method assure if strength repaired pipelines sufficient enough sustain burst pressure loads. A computational model for predicting with CFRP presented. An algorithm artificial neural networks (ANN) applied. geometry corrosion damage de...

INTRODUCTION Ferromagnetic heating is a new electrosurgery energy modality that has proven effective in hemostatic tissue dissection as well as sealing and dividing blood vessels and vascularized tissue. The purpose of this study was to evaluate a ferromagnetic-based laparoscopic vessel sealing device with respect to sealing and dividing vessels and vascularized tissue and to compare performanc...

Two different perspectives on El Niño are dominant in the literature: it is viewed either as one phase of a continual southern oscillation (SO), or alternatively as the transient response to the sudden onset of westerly wind bursts (WWBs). Occasionally those bursts do indeed have a substantial effect on the SO—the unusual strength of El Niño of 1997/98 appears to be related to a sequence of bur...

The detection in 10 bursts of an optical counterpart emission (i.e. during the prompt GRB phase) that is 10−104 brighter than the extrapolation of the burst spectrum to optical frequencies suggests a synchrotron self-Compton origin for the GRB emission, synchrotron producing the optical counterpart emission. In this model, the second upscattering of the burst photons yields a prompt GeV–TeV emi...

The aim of the study was to compare the effect duration of two different protocols of repetitive transcranial magnetic stimulation (rTMS) on saccade triggering. In four experiments, two regions (right frontal eye field (FEF) and vertex) were stimulated using a 1-Hz and a theta burst protocol (three 30Hz pulses repeated at intervals of 100ms). The same number of TMS pulses (600 pulses) was appli...

The role of endogenous cellular properties and network interactions due to electrotonic coupling were investigated in two bilateral populations of 2-7 peripheral neurones ('Peripheral Bursters') in the snail Lymnaea stagnalis. 1. These cells are endogenously capable of bursting. Their burst frequency does not depend on the level of steady membrane polarization. Short hyperpolarizing current pul...
