204 8.8 hen using a cast polyurethane processW ing machine, purging o r flushing the mixing head a t frequent intervals is required. Over the years the standard method of purging has been to blow out most of the polyurethane with air or nitrogen followed by pumping through a solvent. The favored solvent for purging has been methylene chloride (MeCI), which functions well technically. Recently, ...

In this paper we present ideas and architectural principles upon which we are basing the development of a distributed, open-source infrastructure that, in turn, will support the expression of business models, the dynamic composition of software services, and the optimisation of service chains through automatic self-organising and evolutionary algorithms derived from biology. The target users ar...

Patients with a left ventricular assist device (LVAD) have increased risk of gastrointestinal (GI) bleeding. They are prone to develop angiodysplasia of the small intestine, and have a higher risk of bleeding as these patients are all required to be on permanent therapeutic anticoagulation. Here we report a case of a critically ill 55-year-old male on pressors and inotropes with an LVAD, who su...

Formation and accumulation of polycyclic aromatic hydrocarbons (PAHs) are responsible major topical issues related to the conversion petroleum vacuum gas oils (VGOs) in transportation fuels through hydrocracking process. To achieve an efficient management these hydrocarbons, a detailed semi-quantitative description PAHs contained VGOs was provided by three-dimensional off-line analytical approa...

Abstract Background Crohn’s disease (CD) can involve the upper gastrointestinal (GI) tract as well small and large bowel. PillCam colon capsule endoscopy (PCCE-2) enables observation of whole GI tract, but its diagnostic yield for CD lesions in remains unknown. Aim To elucidate PCCE-2 patients with CD. Methods Patients who underwent double-balloon (DBE) using oral anal approaches were evaluated...

Echocardiographic analysis of regional left ventricular function is based upon the assessment of radial motion. Long-axis motion is an important contributor to overall function, but has been difficult to evaluate clinically until the recent development of tissue Doppler techniques. We sought to compare the standard visual assessment of radial motion with quantitative tissue Doppler measurement ...

National (or regional) seismic hazard maps, determined from probabilistic seismic hazard analysis, quantify the expected intensity of shaking in a region(s) over the course of one or more desired time interval(s). Building codes use these maps to define the lateral force levels for the design of new and the retrofit of existing structures. In the past, the maps depicted the shaking intensity me...

Background and study aims Diagnosis of Meckel's diverticulum (MD) before surgery may be challenging; double-balloon endoscopy (DBE) facilitates identification of MD in the setting of a gastrointestinal bleeding; however, MD can be found incidentally without this condition. The purpose of this research was to determine specific characteristic of hemorrhagic MD and incidental MD at DBE. Patients ...
