On the occasion of the 100th anniversary of the detection of the pancreatic diabetes by the two German physicians von Mering and Minkowski the multilayered way of the development lasting for centuries is described. Scientifically this detection deserves particular consideration so far as it was one of the most important and essential prerequisites in search(More)
As intended by its name, Physically Unclonable Functions (PUFs) are considered as an ultimate solution to deal with insecure storage , hardware counterfeiting, and many other security problems. However , many different successful attacks have already revealed vulnera-bilities of certain digital intrinsic PUFs. Although settling-state-based PUFs, such as(More)
This article describes the knowledge-based system THEMPO (Therapy Management in Pediatric Oncology), which supports protocol-directed therapy planning and configuration in pediatric oncology. THEMPO provides a semantic network controlled by graph grammars to cover the different types of knowledge relevant in the domain, and offers a suite of acquisition(More)

In this study is the period of the morphological exploration of the pancreas from the discovery of islets of LANGERHANS (1869) to the discovery of pancreas-diabetes through von MERING and MINKOWSKI (1889) investigated. In his thesis has PAUL LANGERHANS the islets of pancreas and the centro-acinar cells described. In the period from 1869 to 1889 has the(More)

In this study is the history of the pancreas-research between 1889 and 1921 described. In this period are any important discoverys detected: The islets have 2 cell types (TSCHASSOW-NIKOW 1900, 1906); the connection between diabetes mellitus and islet-alterations (OPIE 1900); the independence of islets on exocrine parenchyma (SCHULZE 1900); the discovery of(More)
Spinal Ewing's sarcomas are rare and cause problems in differential diagnosis. The radiologic, nuclear medicine and CT findings in two children with histologically proven Ewing's sarcoma are presented and problems in differential diagnosis discussed. Biopsy should be done early.
