BACKGROUND AND AIMS Plaque fissuring, a phenomenon morphologically distinct from the classical rupture of a thinned fibrous cap, has not been well characterized in carotid atherosclerosis. The aim of this study was to establish the prevalence of plaque fissures in advanced carotid plaques with an otherwise intact luminal surface, and to determine whether they might be a source of intraplaque he...

Fissures substantially impact the engineering stability of rock masses, making research on masses with preexisting fissures essential for activities. The development specimens different fissure types was examined in this study. Three can be broadly categorized: few fissures, multiple and other flaws. Uniaxial compression tests two unequal lengths were conducted, influence angle, distance betwee...

Bituminous crack sealants are used to seal cracks and joints in pavements. In Canada and in regions experiencing harsh climates, sealants often fail prematurely, however. This is, in part, because it is difficult to select the best sealants, those that can withstand demanding conditions, based on the existing ASTM D3405 specification. Consequently, users would like to have a performance-based s...

Earth fissures are widely distributed worldwide, and the Fenwei Basin in China is one of regions with most significant number scale world. The Yuncheng an important constituent basin China, where earth densely developed cause severe damage. In particular, impact on seismic response site still unknown urgent problem that needs to be solved. Based microtremor tests, three types typical fissure si...

The perianal appearances were studied prospectively of 136 constipated children (mean age 3.9 years, 67 boys, 69 girls). Anal dilatation, fissures, tags, warts, perianal oedema, redness, blueness, and veins were recorded. It was noted whether dilatation occurred immediately or at 30 and 60 seconds with the buttocks minimally separated, and on subsequent firm lateral traction of the buttocks. Th...

The purpose of this study was to evaluate the effect of acid conditioning and occlusal sealant on microbial colonization of pit and fissures submitted to ameloplasty or left intact. Human enamel blocks containing fissures prepared from the occlusal surfaces of unerupted third molars were implanted in occlusal fillings in molars of 12 patients for seven, 30, 60, and 120 days. After seven days of...
