The seismic refraction technique has demonstrated its efficiency as a cost-effective geophysical approach for bedrock investigation, which is very important for major construction projects. In the southern part of New Qena City, in the Eastern Desert of Egypt, construction of many domestic facilities is planned. Therefore, a prior investigation focusing on bedrock is required to validate the site for construction and other projects.

Here, a nanospecimen diffracts a single X-ray flash before it disintegrates. The sample structure can be reconstructed from the coherent diffraction image (CDI).

Methods: Patients who underwent curative-intent surgery for CLM from 2001 to 2020 were selected for the study.
Objective: To assess the prevalence of changes on computed tomography (CT) in Graves' orbitopathy (GO) and to correlate those changes with disease activity, as well as with clinical and biochemical variables.
Materials And Methods: This was a retrospective study, conducted at a tertiary hospital, of clinical, biochemical, and imaging data from consecutive patients with GO who underwent at least one orbital CT scan between July 2012 and December 2020. A single observer quantified the thickness of the extraocular muscles and the degree of proptosis.
