A new diffractometer for microcrystallography has been developed for the three macromolecular crystallography beamlines of the Swiss Light Source. Building upon and critically extending previous developments realised for the high-resolution endstations of the two undulator beamlines X06SA and X10SA, as well as the super-bend dipole beamline X06DA, the new diffractometer was designed to the foll...
An automated system for mounting and dismounting pre-frozen crystals has been implemented at the Stanford Synchrotron Radiation Laboratory (SSRL). It is based on a small industrial robot and compact cylindrical cassettes, each holding up to 96 crystals mounted on Hampton Research sample pins. For easy shipping and storage, the cassette fits inside several popular dry-shippers and long-term stor...
Total knee arthroplasty (TKA) is the most common treatment for degenerative osteoarthritis of that articulation. However, either in rehabilitation clinics or in hospital wards, the knee range of motion (ROM) can currently only be assessed using a goniometer. In order to provide continuous and objective measurements of knee ROM, we propose the use of wearable inertial sensors to record the knee ...
Most macromolecular crystallography (MX) diffraction experiments at synchrotrons use a single-axis goniometer. This markedly contrasts with small-molecule crystallography, in which the majority of the diffraction data are collected using multi-axis goniometers. A novel miniaturized κ-goniometer head, the MK3, has been developed to allow macromolecular crystals to be aligned. It is available on ...
Q angle is defined as an acute angle between two imaginary lines drawn from the ASIS to the center of patella and from the center of the patella to the tibial tuberosity. Measuring of Q angle usually was conducted in the supine position by two main methods, invasive methods such as radiography and CT scan and non-invasive methods, including goniometer and photogrammetry. The purpose of this stu...
Purpose: To present a new method of arthroscopic measurement of the surface and location of condylar lesions. Methods: We propose measuring the height of the condylar lesion by using the lesion’s arc (∆°) obtained from the difference between the angle of flexion at the beginning of the lesion and the angle of flexion at the end of the lesion. The first goal of the study was to determine the int...

A mathematical approach has been developed to determine the optical orientation of biaxial minerals by combining spindle stage and X-ray-diffractometer measurements. First, a goniometer head, with crystal affixed, is screwed onto a spindle stage, and its orientation matrix for the biaxial indicatrix is determined. Next, the same goniometer head is transferred to a single-crystal Xray diffractom...
