This paper examines the dowel-bearing strength of laminated flattened-bamboo lumber (LFBL) perpendicular to grain under influence arrangement method, bolt diameter, and specimen size in accordance with ASTM D5764-97a. There were 360 specimens tested total. As a result test results, it was demonstrated that method flattened bamboo panels significantly affected LFBL. In two groups (bolt direction...

The purpose of this research is to evaluate the potential for identifying malignant breast lesions and their margins on large specimen MRI, in comparison to specimen radiography and clinical dynamic contrast enhanced MRI (DCE-MRI). Breast specimens were imaged with an MR scanner immediately after surgery, with an IRB-approved protocol and with the patients' informed consent. Specimen sizes were...

In this paper we investigate which probe size maximizes the throughput when measuring the radius of nanoparticles in high angle annular dark field scanning transmission electron microscopy (HAADF STEM). The size and the corresponding current of the electron probe determine the precision of the estimate of a particle's radius. Maximizing throughput means that a maximum number of particles should...

A 41-year-old female was admitted with respiratory distress. Chest radiographs showed opacity in the right hemithorax with mediastinal shift. Computed tomography (CT) scan showed a pleural mass with a 22 cm diameter occupying the whole right hemithorax and causing atelectasis. Magnetic resonance imaging (MRI) showed lower position of the right hemidiaphragm and the liver. Superior vena cava and...

The numerical investigations of size effects in granular bodies during a quasi-static plane strain compression test are performed. To describe a mechanical behaviour of a cohesionless granular material during a monotonous deformation path in a plane strain compression test, a micro-polar hypoplastic constitutive model was used. It includes particle rotations, curvatures, non-symmetric stresses,...

Laboratory fracture toughness tests of concrete using wedge-loaded round double beam specimens with a length to diameter ratio of 2:1 show two distinctly different specimen behaviors. Either the crack remains in the plane of the notch, and a valid test result can be obtained, or there is lateral cracking around mid-length which invalidates the results. Results of a controlled study show that th...

This study compared gradient gel electrophoresis (GGE) and light-scattering (LS) methods of determining low density lipoprotein (LDL) particle size. LDL was isolated from 27 fasting subjects. Peak particle size was determined by GGE on 3-13% gradient gels (Gradipore, Sydney, Australia) and by LS using a Zetasizer 3000 (Malvern Instruments, Malvern, UK). Repeated measurements on a single specime...

The membrane penetration effect will significantly influence the measurement of specimen volume deformation in triaxial test. This paper presents a novel procedure for measuring and correcting rubber by using newly developed multiscale apparatus. A series tests on coarse granular materials was conducted with different diameters, it is found that proportion change due to decreases linearly incre...
