Three-dimensional (3D) reconstruction experiments were carried out by observing high-resolution 3D electrostatic potential distributions of Pt nanoparticles using off-axis electron holographic tomography. These Pt nanoparticles were mounted on the surfaces of amorphous silicon pillars. In order to realize high-resolution observation, we developed a mechanically stable 3D specimen holder with sm...

A an initial diagnostic procedure in diffuse and localized lung disease, transbronchial lung biopsy ( TBB ) offers an attractive alternative to open lung biopsy. In the past, TBB was carried out by inserting a flexible forceps through a rigid, opentube bronchoscope or a catheter.’5 More recently, this technique has been popularized by passing the forceps through the channel of a flexible fibero...

Image analysis technique is introduced to characterize fiber distribution in steel fiber reinforced cementitious composites. Through cutting and polishing of specimen, image acquisition of specimen surface, extraction of fiber feature, and measurement of related fiber parameters, i.e., dispersion coefficient and orientation factor, are given to quantitatively analyze fiber distribution. Effects...

When measuring the compressive strength of rock, size and strain rate are two main influencing factors. To study rock effect, specimens with length-to-diameter ratios 0.5, 0.6, 0.7, 0.8, 0.9 1 were subjected to static loading tests using RMT mechanics test system dynamic split Hopkinson pressure bar, respectively. Based on Weibull size-effect formula, experimental results compared improved form...

INTRODUCTION Insulinomas are the most common endocrine tumours of the pancreas. They are more frequent in females, and they are commonly less than 2 cm in diameter. If conservative treatment of typical clinical symptoms fails, detailed diagnostic procedures are necessary and surgical treatment is indicated.The aim of this report was to emphasize the need of pancreatic resection when insulinoma ...

There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...
