To obtain such positron microbeam, it is necessary to use objective lenses, which are commonly used in the electron microscopy. We also attempted to form the positron microbeam using a positron beam for the positron diffraction experiment and a SEM optics [6]; [7] ; [8].
1 BERLIN â Ikea has long been famous for its inexpensive, some-assembly-required furniture. 2  A report by auditors at Ernst & Young concluded that Ikea, a Swedish company, knowingly benefited from forced labor in the former East Germany to manufacture some of its products in the 1980s.

The Soviet system of forced labor camps was first established in 1919 under the Cheka, but it was not until the early 1930s that the camp population reached significant numbers.fter Stalin died in 1953, the Gulag population was reduced significantly, and conditions for inmates somewhat improved. Forced labor camps continued to exist, although on a small scale, into the Gorbachev period, and the government even opened some camps to scrutiny by journalists and human rights activists.
