UNLABELLED In response to U.S. Pharmacopeia general chapter <797> standards, a clean room was constructed for our in-house radiopharmacy. Previously, most patient doses were prepared as needed just before injection. Currently, to minimize repeated entries into the clean room, most patient doses are prepared in batches; that is, early morning and noontime preparation of doses to be injected at v...

The discovery of the topological states has become a key topic in condensed matter physics with focus evolving from Dirac or Weyl points to high-dimension nodal lines and surfaces. For material manifest its quantum properties useful applications, need be genuine clean so that they lie close Fermi level without other trivial bands existing at level. While number materials are predicted, only few...

The main features of the lazy functional language Concurrent Clean and of its semantics based on Term Graph Rewriting are presented. 1 History The pure, lazy functional language Concurrent Clean (version 1.0) is a major upgrade of the previous release (0.84b) of Clean ((3,10,11]). Clean was originally designed as an experimental intermediate language and deliberately kept syntactically as poor ...

In diesem Beitrag wird der Zusammenhang zwischen Code-Qualität und UMLModellen in einem Software-Entwicklungsprozess in der Informatik-Ausbildung vorgestellt. Es wird untersucht, welche der im Code sichtbar werdenden Mängel bereits im Modell erkannt werden können. Werkzeuge zur statischen Code-Analyse und Refactoring-Techniken unterstützen die Studierenden beim Entdecken und Beseitigen der Qual...

Bulk analysis of environmental swipe samples taken within nuclear installations as part of routine IAEA inspections has proven to be a very sensitive analytical technique. The combination of chemical separations under very clean conditions with highly sensitive mass spectrometric measurements assists in the identification and characterization of uranium and plutonium signatures at ultratrace le...

One-loop off-shell contributions to the three-gluon vertex are calculated, in arbitrary covariant gauge and in arbitrary space-time dimension, including quark-loop contributions (with massless quarks). It is shown how one can get the results for all on-shell limits of interest directly from the general off-shell expression. The corresponding general expressions for the one-loop ghost-gluon vert...

The potential of a Super Flavor Factory (SFF) for searches of New Physics is reviewed. While very high luminosity B physics is assumed to be at the core of the program, its scope for extensive charm and τ studies are also emphasized. The possibility to run at the Υ(5S) as well as at the Υ(4S) is also very briefly discussed; in principle, this could provide very clean measurements of Bs decays. ...

In quantum solids composed of fermion particles, such as helium-3 and electrons, the low-temperature physics is governed by spin exchanges, according to the Thouless theory. We present path integral Monte Carlo calculations of ring exchange energies on ‘clean’ two-dimensional crystals of both helium-3 and electrons. We see a remarkable similarity of the results for these two ‘opposite’ systems....
