The platform enabled the validation of critical aseptic parameters. In parallel, one series of microbiological count reduction tests was performed using highly resistant spores of B. atrophaeus DSM 675 to act as the reference method for sterility validation. By means of the multi-sensing platform together with microbiological tests, we examined sterilization process parameters to define the most effective conditions with regards to the highest spore kill rate necessary for aseptic packaging. As these parameters are mutually associated, a correlation between different factors was elaborated. The resulting correlation indicated the need for specific conditions regarding the applied H₂O₂ gas temperature, the gas flow and concentration, the relative humidity and the exposure time. Finally, the novel multi-sensing platform together with the mobile electronic readout setup allowed for the online and on-site monitoring of the sterilization process, selecting the best conditions for sterility and, at the same time, reducing the use of the time-consuming and costly microbiological tests that are currently used in the food package industry.}, language = {en} } @article{InfantinoPaulssenMostaccietal.2016, author = {Infantino, Angelo and Paulßen, Elisabeth and Mostacci, Domiziano and Schaffer, Paul and Trinczek, Michael and Hoehr, Cornelia}, title = {Assessment of the production of medical isotopes using the Monte Carlo code FLUKA: Simulations against experimental measurements}, series = {Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms}, volume = {366}, journal = {Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1872-9584}, doi = {10.1016/j.nimb.2015.10.067}, pages = {117 -- 123}, year = {2016}, abstract = {The Monte Carlo code FLUKA is used to simulate the production of a number of positron emitting radionuclides, ¹⁸F, ¹³N, ⁹⁴Tc, ⁴⁴Sc, ⁶⁸Ga, ⁸⁶Y, ⁸⁹Zr, ⁵²Mn, ⁶¹Cu and ⁵⁵Co, on a small medical cyclotron with a proton beam energy of 13 MeV. Experimental data collected at the TR13 cyclotron at TRIUMF agree within a factor of 0.6 ± 0.4 with the directly simulated data, except for the production of ⁵⁵Co, where the simulation underestimates the experiment by a factor of 3.4 ± 0.4. The experimental data also agree within a factor of 0.8 ± 0.6 with the convolution of simulated proton fluence and cross sections from literature.

Bei den Bildschirmsystemen wird zwischen zwei Arten unterschieden. Aktive Bildschirmeinheiten besitzen als {\"a}ußeres Merkmal einen Lichtstift und eine Funktionstastatur zur Programmverzweigung. Passive Bildschirmeinheiten lassen demgegen{\"u}ber einen Eingriff in das Programm in der oben aufgef{\"u}hrten Form nicht zu. Zwischen diesen extremen Formen gibt es noch eine Reihe Mischformen.
