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...

OBJECTIVE We aimed to evaluate the direct costs of pulmonary lobectomy hospitalization, comparing surgical techniques for the division of interlobar fissures: stapler (ST) versus electrocautery and hemostatic sealant patch (ES). METHODS The cost comparison analysis was based on the clinical pathway and drawn up by collecting the information available from the Thoracic Surgery Division medical...

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...

Air leaks are a common complication of pulmonary resection. The aims of this study were to analyze risk factors for postoperative air leak and to evaluate the role of air leak measurement in identifying patients at increased risk for cardiorespiratory morbidity and prolonged air leak. From March to December 2009, 142 consecutive patients underwent pulmonary resection for malignancy and were pro...

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...

Radiol Bras. 2013 Jan/Fev;46(1):IX In this volume of Radiologia Brasileira, our readers can find an interesting paper from Koenigkam-Santos et al.. The study from the department of Prof. Kauczor and Prof. Heussel describes the results of their research on the pre-operative assessment of the completeness of the lung fissures and pre and post operative quantification of lung volumes and emphysema...

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...

The morphological features of disproportionately enlarged subarachnoid-space hydrocephalus (DESH), the core type of idiopathic normal pressure hydrocephalus, can not be explained by the classical theory of CSF absorption at the arachnoid villi and the hypothesis of CSF flow blocking at the convexity subarachnoid spaces. By using MRI Time-SLIP CSF flow imaging, we demonstrated that CSF freely mo...

AIM Sealing of pits and fissures is one of the most effective techniques in caries prevention: however incomplete removal of plaque debris, can cause lack of retention of the sealant. MATERIALS AND METHODS Sixty first permanent molars were sealed for this study. The teeth were divided into four groups. All teeth were isolated with a dental dam before cleaning and coronal polishing was perform...
