In this paper we investigate a microfluidic device designed for separation of particles having different densities. Separating mechanism employs Standing Surface Acoustic Waves (SSAWs). Simulation studies have shown that Polyethylene microspheres with diameter of 10μm, having a density of 1200 kg/m3, can easily be detected from the same sized Melamine microspheres having a density equal to 1710...

Infinite families of linear binary nested completely regular codes with covering radius ρ equal to 3 and 4 are constructed. In the usual way, i.e., as coset graphs, infinite families of embedded distance-regular coset graphs of diameter D = 3 or 4 are constructed. In some cases, the constructed codes are also completely transitive codes and the corresponding coset graphs are distance-transitive.

In 526 patients undergoing a first percutaneous transluminal coronary angioplasty (PTCA) of a single native vessel, we studied the influence of length and eccentricity of the lesion on complications and primary success. Long stenoses (greater than or equal to 5 mm, n = 153) did not differ from short stenoses (less than or equal to 4 mm, n = 265) in terms of overall complications or gain in lume...

BACKGROUND In a study of normal and abnormal growth of the aorta before birth, high-resolution echocardiographic imaging of the aortic arch in 92 normal fetuses aged 16-38 weeks was used to establish normal values for aortic arch dimensions at varying gestational ages. METHODS AND RESULTS From long-axis views of the aortic arch, the internal diameter of the aortic root, ascending aorta, trans...

BACKGROUND Many types of projectiles, including modern hollow point bullets, fragment into smaller pieces upon impact, particularly when striking bone. This study was performed to examine the effect on time to union with retained bullet material near a fracture site in cases of gunshot injury. METHODS All gunshot injuries operatively treated with internal fixation at a Level 1 Trauma Center b...

An experiment was conducted to describe the characteristics of Angora rabbit fiber using optical fiber diameter analyzer (OFDA). A total of 349 fleece samples were collected from 60 French Angora rabbits. Recorded measurements of OFDA were as follows: mean fiber diameter, CV of fiber diameter, comfort factor, spinning fineness, mean fiber curvature, SD of fiber curvature, mean opacity of fibers...

the objective of the present study was to scan the whole genome in sheep for identifying the loci associated with wool diameter. blood samples were collected from 94 animals, consisting 47 samples per each lori-bakhtiary and zel breeds. genotyping of samples were performed using ovine 50k snp chip arrays. quality control filters were applied for the initial genotyping data and 48,056 snps belon...
