To study endocardial wall motion and thickness as indexes of infarction, we used two-dimensional echocardiography to examine regional percentages of systolic wall thickening (%Th) and endocardial motion (%EM) in infarcted canine hearts. Thirteen dogs were studied 48 hours after occlusion of the circumflex or left anterior descending coronary artery. Two-dimensional echocardiographic cross secti...

Wavelet Transform was applied to Acoustic Emission (AE) signals from Scratch Tests (ST) on stainless steel samples with Cr and Ti nitride surface coatings obtained by PVD. The implementetion of the signal processing method was aimed at characterizing the coating failure stages and evaluating the quality of and the differences between both type of coatings. In previous work we had identified dif...

and S. L. MillerFrost Advances in global network connectivity over the past 10 years have significantly reduced the effects that physical separation has on geographically distributed development teams. It is increasingly clear that time zones, rather than physical distances, are becoming the most significant factor which separates potential collaborators. Collaboration across time zones often i...

We have studied the intrinsic connections of the anterior dorsal ventricular ridge (ADVR) in the lacertid lizard Psammodromus algirus by means of retrograde transport of horseradish peroxidase (HRP) and fluorescent labeling with the lipophilic carbocyanine dye DiI. We injected HRP into different regions in the ADVR arrayed in a medial-to-lateral sequence, with each consisting of three distinct ...

Streptococci that were dependent for their growth upon staphylococci were isolated from a patient with sub-acute bacterial endocarditis and subsequently identified as nutritionally-variant streptococci (NVS). Failure of the isolate to grow on agar media supplemented with pyridoxal hydrochloride or L-cysteine, the known supporting growth factors for NVS, made conventional antimicrobial disc diff...

Ocean acidification is predicted to impact all areas of the oceans and affect a diversity of marine organisms. However, the diversity of responses among species prevents clear predictions about the impact of acidification at the ecosystem level. Here, we used shallow water CO(2) vents in the Mediterranean Sea as a model system to examine emergent ecosystem responses to ocean acidification in ro...

In thin-layered reservoirs, drilling engineers face tough challenges—planning their drilling programs to follow the most productive reservoir layers while avoiding nearby water, gas or high-pressure zones. The rewards for a successful drilling strategy are clear—increased oil production and reduced water cut. In an oil field in the Persian Gulf, for example, oil production was increased four- t...

Different types of iron oxides deposits have been identified along the Khaf – Dorouneh volcanic and plutonic belt in north east of Iran. Kuh-e-Zar is one of these ore deposits known as Fe- oxide gold deposit. The main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the ETM+ data. Data processing has been done by ENVI (Environment for Visualizing...

Non bacterial thrombotic endocarditis presenting as a stroke is a rare presentation as a result of an underlying occult ovarian clear cell adenocarcinoma. Embolic events secondary to non bacterial thrombotic endocarditis are potentially a life-threatening condition if not diagnosed and treated promptly. High clinical suspicion for an underlying neoplasm is one of the key elements to be consider...
