Research complex linac-300 upgrade project and the lines of nuclear research

The paper describes the problems of upgrading the research complex LINAC-300 and the program of physical studies expected to be performed at it. The acceleration complex LINAC-300 includes three electron beam ejection channels, the beam translation system and the spectrometer SP-95. Some special features of already upgraded systems of the complex LINAC-300 are considered in detail, as well as the plan of activities for its further modernization is given together with the expected electron beam characteristics. Special attention is paid to the program of physical investigations that are underway or expected to be performed at the experimental complex.Робота присвячена питанням реконструкцiї дослiдницького комплексу ЛПЕ-300 та програмi фiзичних дослiджень якi на ньому плануються.

A review is given about electron linacs of NSC KIPT and their some applications for research of radiation effects in reactor materials, channeling, plasma-beam interactions, geology (gamma-activation analysis of ore samples), as well as sterilization of single-use medical products, modification of polymers and semiconductors, isotope production for nuclear medicine etc

Age at first birth in women is genetically associated with increased risk of schizophrenia

Prof. Paunio on PGC:n jäsenPrevious studies have shown an increased risk for mental health problems in children born to both younger and older parents compared to children of average-aged parents. We previously used a novel design to reveal a latent mechanism of genetic association between schizophrenia and age at first birth in women (AFB). Here, we use independent data from the UK Biobank (N = 38,892) to replicate the finding of an association between predicted genetic risk of schizophrenia and AFB in women, and to estimate the genetic correlation between schizophrenia and AFB in women stratified into younger and older groups. We find evidence for an association between predicted genetic risk of schizophrenia and AFB in women (P-value = 1.12E-05), and we show genetic heterogeneity between younger and older AFB groups (P-value = 3.45E-03). The genetic correlation between schizophrenia and AFB in the younger AFB group is -0.16 (SE = 0.04) while that between schizophrenia and AFB in the older AFB group is 0.14 (SE = 0.08). Our results suggest that early, and perhaps also late, age at first birth in women is associated with increased genetic risk for schizophrenia in the UK Biobank sample. These findings contribute new insights into factors contributing to the complex bio-social risk architecture underpinning the association between parental age and offspring mental health.Peer reviewe
