Title: Ionizing Radiation – what is the risk of cancer at low doses?
Abstract: There exists a vast number of studies of biological effects of ionizing radiation, mostly dedicated to radiation-induced cancers. Whereas the field of early effects is quite well understood, the low doses (below, say, 100 mGy) that may at best create only late or very late delatorious effects are a subject of on-going research. Estimation of a cancer risk for low doses or ionizing radiation requires universal biology-based model taking into account essential processes that take place in irradiated cells. I will try to present a relatively simple approach which can show what could be expected for the dose-effect dependence in the colony of cells as well as theoretical background of this subject.

Title: High performance computer processing and computational fluid dynamics
Abstract: The presentation consists of two part. In the first one a general introduction to high performance computing will be given including basic information of two main programming standards: Message Passing Interface (MPI) and Open Multi-Processing (OpenMP). The second part will be devoted to solving the problems of computational fluid dynamics on CIS cluster. In particular ANSYS tools, like Fluent, available at NCBJ will be presented, basing on exemplary simulations for nuclear application reasoning the use of HPC.
Speakers: Michał Wójcik, Piotr Wasiuk, Henryk Giemza

Title: Hypernuclear physics with ALICE at LHC
Abstract: Hypernucleus was first discovered in Warsaw. A historic prospective of its discovery will be presented. A short review of strangeness in particle physics will be followed by a brief discussion of the importance of the study of hypernuclei in varios fields of physics. The study of production of Hypertritium and Antihypertritium in the ALICE experiment will be presented. Its measured yield and lifetime will be compared with theoretical models and various results obtained with ALICE will be discussed.

Title: Application of the Recombination Microdosimetric Method into Mixed Radiation Dosimetry
Abstract: Recombination methods can be applied in the radiation fields of poorly known composition and practically unlimited energy range. Main dosimetric parameters, such as absorbed dose, photon component to the absorbed dose, radiation quality factor, dose equivalent, ambient dose equivalent and some other can be determined with a single instrument. During the lecture will be presented the application of such methods to experimental results.
