Establishing Trafficking in Human Beings for the Purpose of Organ Removal and Improving Cross-Border Collaboration in Criminal Cases: Recommendations.

In this short summary report on the legal definition of trafficking in human beings for the purpose of organ removal and improving cross-border collaboration in criminal cases, challenges, and recommendations in the areas of defining the crime, criminal investigation and prosecution, and cross-border cooperation are made. These are the outcomes of a working group discussion during the writers' conference of the HOTT project, a European Union-funded project against trafficking in human beings for the purpose of organ removal.

Active optics system of the VLT Survey Telescope.

This paper describes the active optics system of the VLT Survey Telescope, the 2.6-m survey telescope designed for visible wavelengths of the European Southern Observatory at Cerro Paranal, in the Atacama desert. The telescope is characterized by a wide field of view (1.

Removing static aberrations from the active optics system of a wide-field telescope.

The wavefront sensor in active and adaptive telescopes is usually not in the optical path toward the scientific detector. It may generate additional wavefront aberrations, which have to be separated from the errors due to the telescope optics. The aberrations that are not rotationally symmetric can be disentangled from the telescope aberrations by a series of measurements taken in the center of the field, with the wavefront sensor at different orientation angles with respect to the focal plane.

Active optics control of VST telescope secondary mirror.

In telescopes based on active optics, defocus and coma are usually compensated for by secondary mirror movements. They are performed at the Very Large Telescope Survey Telescope (VST) with a hexapod--a parallel robot with six degrees of freedom positioning capability. We describe the application of the two-mirror telescope theory to the VST case and the solutions adopted for the hexapod control.

Active optics primary mirror support system for the 2.6 m VST telescope.

The Very Large Telescope Survey Telescope (VST) is equipped with an active optics system in order to correct low-order aberrations. The 2.6 m primary mirror is supported both axially and laterally and is surrounded by several safety devices for earthquake protection.
