We describe X-ray computed tomography (CT) datasets from three specimens recovered from Early Cretaceous lakebeds of China that illustrate the forensic interpretation of CT imagery for paleontology. Fossil vertebrates from thinly bedded sediments often shatter upon discovery and are commonly repaired as amalgamated mosaics grouted to a solid backing slab of rock or plaster. Such methods are pro...
Advanced applications of materials need sophisticated measurement methods for research, process development and quality control. X-ray Computed Tomography (CT) is a very powerful method for non-destructive testing of materials. A CT-scanner generates a series of X-ray attenuation measurements, which are used to produce computed reconstructed images of an object. In the last years 3D-CT systems ...
Background: F-FDG PET/CT imaging is widely utilized in the clinical evaluation of patients with suspected or documented lymphoma. The aim was to describe our cumulative experience with a multimodal F-FDG-directed lymph node surgical excisional biopsy approach in patients with suspected lymphoma. Methods: Thirteen patients (mean age 51 (±16;22–76) years), with suspected new or suspected recurren...
CT scanning uses X-rays crossing the sample to image sections of the specimen in study. Specimen can be a living being, a part of if (e.g. the abdomen, a knee, the head, ...) or whatever non-living object. X-rays travel ballistically inside most of the materials (living tissue included), so measuring absorption of X-rays we can guess the composition of the sample we are measuring. Changing the ...
The safety and efficacy of an implantable left atrial pressure (LAP) monitoring system is being evaluated in a clinical trial setting. Because the number of available specimens from the clinical trial for histopathology analysis is limited, it is beneficial to maximize the usage of each available specimen by relying on integrated microscopy techniques. The aim of this study is to demonstrate ho...
During the Ebola virus outbreak of 2013-2016, the Viral Special Pathogens Branch field laboratory in Sierra Leone tested approximately 26 000 specimens between August 2014 and October 2015. Analysis of the B2M endogenous control Ct values showed its utility in monitoring specimen quality, comparing results with different specimen types, and interpretation of results. For live patients, blood is...
Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed temperatures up to 560°C. This paper presents the numerical simulation a CT-specimen, using finite element method. The analysis was performed Ansys Workbench R21, represents initial stage extensive research involving behaviour steel. goal simulate real experimental conditions, including boundary conditions lo...
Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...
