Recently, the enterprise application integration has been a crucial requirement for the progress of EIS. However, the integration of those heterogeneous or distributed information systems often encounters problems related to complex management and maintenance, as well as low compatibility. Nevertheless, to totally abandon the former system or to re-develop a new great EIS may result in costly i...

In the commentary to our paper [Electrochimica Acta 63 (2012) 55], Roling and Drüschler raised a very important issue regarding the measurements and comparison of the differential and integral capacitances retrieved using electrochemical impedance spectroscopy (EIS). They clearly explained that EIS measures differential capacitance rather than integral capacitance. The present letter aims to co...

we study copper corrosion inhibition by ethanolamine (eta)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm nacl solution. this work is carried out by potentiodynamic measurements and electrochemical impedance spectroscopy (eis). the substrates' surface morphologies are examined by scanning electron microscopy (sem). etais characterized by nmr spectra of eta1h and 13c and fourier ...

steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. consequently, electrochemical impedance spectroscopy (eis) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect and electrolyte type, on cathodic di...

An embedded system is a small autonomous computer system that is encapsulated in the device it is controlling. Examples of device with embedded systems are TVs, microwaves, and dishwashers. A modern car can hold as much as 60 microprocessors. Embedded systems sales are rapidly increasing. In fact processor sales for embedded system are much larger than those for personal computers. PC processor...

Background: Endoscopic injection sclerotherapy (EIS) is one of the most commonly applied techniques in the treatment of patients with esophageal varices (EV) bleeding. However, the role of EIS in the long-term management of patients with EV bleeding remains controversial. We conducted a retrospective 30-year survey of EIS in patients with EV bleeding. Patients and Methods: Sclerosant with radio...

This paper aims to clarify the intrinsic limitations of electrochemical impedance spectroscopy (EIS) in measuring electric double layer (EDL) capacitance. For more than two decades, capacitances measured using EIS at low frequencies have been reported to be significantly smaller than those measured using other techniques without any definitive explanations. In this paper, EIS measurements were ...

BACKGROUND AND PURPOSE Previous acute stroke studies found diffusion-weighted (DW) imaging superior to CT for detection of early ischemic signs (EIS). However, these findings were confounded by a large time interval in favor of DW imaging. We compared DW images and CT scans obtained with a short time delay in patients with acute stroke to define the sensitivity and interrater agreement of both ...

Intracellular survival plays a central role in the pathogenesis of Mycobacterium tuberculosis. To identify M. tuberculosis genes required for intracellular survival within macrophages, an M. tuberculosis H37Rv plasmid library was constructed by using the shuttle vector pOLYG. This plasmid library was electroporated into Mycobacterium smegmatis 1-2c, and the transformants were used to infect the...

The seed oil of Crepis eonyzaefolia (Gouan) Daile Torre contains previously unidentified (± )-eis-12,13epoxyoctadeca-trans-6-cis-9-dienoic (14 and eis-12,13-epoxyoctadeca-cis-6-cis-9-dienoic (2 ~{) acids and the more common vernolic [( ±)-12,13-epoxyoctadec-cis-9-enoic] (32 %) acid.
