Vanillin is an interesting corrosion inhibitor because of its safe use and high solubility inwater. The effect of vanillin on the corrosion inhibition of carbon steel in 1.0 Mhydrochloric acid solution has been studied using potentiodynamic polarization,electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques.The effect of temperature on the rate of corrosion in th...

Stroke complicating infective endocarditis (IE) poses a therapeutic dilemma, particularly in patients with prosthetic valves (PV). Most experts recommend against the use of anticoagulation because of increased risk of intracerebral hemorrhage (ICH). Some worry that stopping anticoagulation increases the risk of clot formation on the PV and further embolization. Brain embolization in the setting...

The effect of Mentha spicata L. extract on the corrosion behaviour of carbon steel in 1.0 M HCl solution was investigated using polarization, electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (IE). The effect of temperature on the rate of corrosion ...

How do we scale information extraction to the massive size and unprecedented heterogeneity of the Web corpus? Beginning in 2003, our KnowItAll project has sought to extract high-quality knowledge from the Web. In 2007, we introduced the Open Information Extraction (Open IE) paradigm which eschews handlabeled training examples, and avoids domainspecific verbs and nouns, to develop unlexicalized,...

A standardized protocol for the evaluation of hand disinfection by surgical scrub formulations was applied to volunteers in a multicenter trial. Povidone iodine (PVI), chlorhexidine (CHX), and a nonmedicated soap (NMS) were tested. The scrubbing procedure involved three daily hand washings for five consecutive days; surviving bacteria were counted daily after being collected in a suitable neutr...

Information in visually rich formats such as PDF and HTML is often conveyed by a combination of textual and visual features. In particular, genres such as marketing flyers and info-graphics often augment textual information by its color, size, positioning, etc. As a result, traditional text-based approaches to information extraction (IE) could underperform. In this study, we present a supervise...

Correspondence Aspirin Use in Infective Endocarditis To the Editor—Chan et al. [1], are to be congratulated for their prospective in-terventional study of aspirin use in patients with infective endocarditis (IE). Their study did not fin that aspirin reduced the frequency of major embolic events and showed a trend towards an increase in the number of major bleeding episodes in the intervention g...
