designs were considered – such as ones involving collimation by Al or heavier materials that may allow some screening of annihilations coming directly from the source, but all were found to have some disadvantage.
Finally it was decided that a source with no backing material and no collimation provided the best results.

Software package includes the databases, which store the materials of predefined courses, a tool for presentation of materials in the network (including multimedia and interaction with the system), logging mechanisms and mechanisms for recognition of students and lecturers, tools for for assessment of academic progress, e-mail, forums, chat.
Another element are additional tools for creating the content, eg. interactive materials, multimedia presentations, educational games, project management, testing of knowledge and many others.
Description of research Materials and methods.
These include first and foremost: - students skip e-learning courses as they treat it as addition to contact classes, - perfunctory studying of e-learning materials, - Low quality of e-learning materials, - improper selection of issues to be taught with e-learning (knowledge versus skills).

With the appearance of advanced technologies and materials, there is an increasing need for dies that can accurately produce parts with complex geometries, particularly in the aerospace, automotive, and electronics sectors [2].
Machining accuracy was evaluated based on the amount of leftover material.
In this study, NAK80 (hardness 40HRC), a common metal for molds, was used as the workpiece material.
