Opis:: Neptunium-237 samples were irradiated in a spallation neutron fi eld produced in accelerator-driven system (ADS) setup QUINTA. Five experiments were carried out on the accelerators at the JINR in Dubna – one in carbon (C6+), three in deuteron, and one in a proton beam. The energy in carbon was 24 GeV, in deuteron 2, 4 and 8 GeV, respectively, and 660 MeV in the proton beam. The incineration study method was based on gamma-ray spectrometry. During the analysis of the spectra several fi ssion products and one actinide were identifi ed. Fission product activities yielded the number of fi ssions. The actinide (Np-238), a result of neutron capture by Np-237, yielded the number of captures. The main goal of this work was to fi nd out if and how the incineration rate depended on parameters of the accelerator beam.

Opis:: Objective. The aim of this study is to evaluate neurological scales, as well as biochemical and radiological parameters measured on day 10 after ischemic stroke (IS), according to their value as predictors of the long-term outcome. Materials and method. 45 patients were assessed according to the Barthel Index (BI) and National Institute of Health Stroke Scale (NIHSS) on day 10, and according to Modified Rankin Scale (mRS) 3 months after the onset of IS. On day 10 of IS, the serum level of C-reactive protein (CRP), albumin, D-dimers (DD), S100BB and Tau proteins was measured and the volume of ischemic focus assessed with the use of Computed Tomography (CT). The patients were divided into groups with good outcome (GO) and mRS 0–2, and with bad outcome (BO) and mRS 3–6. Results. NIHSS and BI scores (p<0.001), the volume of ischemic focus (p<0.01), CRP (p<0.01) and albumin level (p<0.05), but not DD, S100BB and Tau protein levels evaluated on day 10, correlated with mRS after 3 months since IS onset. Patients from the BO group were observed to have lower BI (p=0.001), higher NIHSS (p<0.01) and CRP levels (p<0.05), and bigger volume of ischemic focus (p<0.05) measured on day 10 of IS. In the GO group, there were more patients with atherosclerotic etiology (p=0.02 x2=7.856). Regression analysis showed that only the BI score assessed on day 10 of IS can predict the outcome after 3 months assessed by mRS (OR=1.102, 95%, CI:1.01–1.203; p=0.001). Conclusions. BI assessed on day 10 has a predictive value for the outcome evaluated by mRS 3 months after the onset of IS.
