    The paper presents the list of spontaneous medicinal plants in Romania, for each taxon being indicated the scientific and vernacular name, the type of collection and plant organs collected. A special mention is made for medicinal plants in Romania that are included on the Red Lists. For these a series of recommendations are made regarding their collection from the spontaneous flora and special protection measures

    The development of a physical model of an advanced gas cooled reactor core: Outline of the feasibility study

    The ageing issues of the Advanced Gas Cooled Reactor (AGR) cores need addressing to maintain their safe and reliable operation, hence the requirement for the computer models of the cores used for the seismic resilience assessments to be conservative and to represent larger percentages of damaged graphite components. The current models have undergone limited experimental validation for high levels of degradation, so there is a need to validate those numerical models and also to enhance the understanding of core dynamics by physical modelling and testing. This paper outlines the feasibility study of a quarter scale model rig of an AGR core developed by the University of Bristol. The damage scenarios to be considered in demonstrating the core seismic tolerability were defined. The principles of scale modelling were put under scrutiny in parallel with several practical aspects of material selection and component design and manufacturing. Several variants of physical models of different size and shape were proposed and their merits with respect to their feasibility and outcomes were discussed. Aspects of instrumentation design are presented together with relevant measurement results. The rig is a viable experimental tool whose outputs can be employed directly in computer model validation

    AREAL LIMIT IN THE ROMANIAN TERRITORY: 6. SECALE STRICTUM

    In this paper are presented data on the areal limit of the species Secale strictum (C. Presl) C. Presl on the Romanian territory. There are included observations on species distribution in Romania and also some ecological and coenological considerations. Secale strictum is one of the Poaceae species rarely found by botanists and therefore less researched. It is a species with southern area which does not pass north of the Carpathian
