- Double-differential cross sections for neutron production were measured in 96-MeV neutron-induced reactions at The Svedberg Laboratory in Uppsala, Sweden. Measurements for Fe and Pb targets were performed using two independent setups: DECOI-DEMON, time-of-flight telescope dedicated to the detection of emitted neutrons with energies between a few and 50 MeV and CLODIA-SCANDAL device devoted to measuring emitted neutrons with energies above 40 MeV. Double-differential cross sections were measured for an angular range between 15 and 98 deg and with low-energy thresholds (approximate to 2 MeV). Angular and energy distributions and total neutron emission cross sections have been obtained from those measurements. Results have been compared with predictions given by different models included in several transport codes (MCNPX, GEANT, TALYS, PHITS, and DYWAN) and with other experimental data (the EXFOR database).

- Recent socio-economic changes, developments in school policy, and increased migration have added new dimensions to debates about educational inequalities. They concern one of the major challenges facing Sweden today, which is to offer all its students an equal education. What we know so far is that growing up in a disadvantaged neighbourhood with high rates of poverty, joblessness, and single parenthood are often used to explain lower levels of schooling, but that their mechanisms and interactions are not well understood. This is the focus of the present article. In it we use meta-ethnography to explore expressions about the education experiences of youths from suburban areas with high levels of unemployment and migration and educational performances lower than the national average to try to cast further light on these problems. We suggest that the common arguments used to account for the problem of school performance are strongly correlated with proficiency in the language of instruction and socio-economic conditions, but that these factors cannot account for the full extent of the problem. What it means to live within specific multicultural urban contexts is important as is the segregation and media representation of these areas and those who live in them.

- Inelastic neutron scattering for (12)C, (58)Fe, (89)Y and (208)Pb have been measured at 96 MeV at the The Svedberg Laboratory in Uppsala and double-differential cross sections are reported. Data cover an excitation energy range of 0-45 MeV and the angular intervals are 28 - 58 degrees for (12)C, 26 - 65 degrees for (58)Fe and 26 - 52 degrees for (89)Y and (208)Pb. In this experiment, neutron detection is based on conversion to protons in an active scintillator converter. An analysis technique in which the neutron spectra have been obtained through a folding procedure using the response of the detector system has been used. The results are compared to and are in reasonable agreement with several model predictions and with inelastic neutron scattering data at 65 MeV from University of California, Davis, USA.
