Review of even element super-heavy nuclei and search for element 120

Abstract: The reaction 54Cr$ + $248Cm was investigated at the velocity filter SHIP at GSI, Darmstadt, with the intention to study production and decay properties of isotopes of element 120. Three correlated signals were measured, which occurred within a period of 279ms. The heights of the signals correspond with the expectations for a decay sequence starting with an isotope of element 120. However, a complete decay chain cannot be established, since a signal from the implantation of the evaporation residue cannot be identified unambiguously. Measured properties of the event chain are discussed in detail. The result is compared with theoretical predictions. Previously measured decay properties of even element super-heavy nuclei were compiled in order to find arguments for an assignment from the systematics of experimental data. In the course of this review, a few tentatively assigned data could be corrected. New interpretations are given for results which could not be assigned definitely in previous studies. The discussion revealed that the cross-section for production of element 120 could be high enough so that a successful experiment seems possible with presently available techniques. However, a continuation of the experiment at SHIP for a necessary confirmation of the results obtained in a relatively short irradiation of five weeks is not possible at GSI presently. Therefore, we decided to publish the results of the measurement and of the review as they exist now. In the summary and outlook section we also present concepts for the continuation of research in the field of super-heavy nuclei.

Culture and identity in higher education research

Abstract: The aim of this article is to develop a cultural approach in higher education studies. It will be argued that the cultural approach is rooted mainly in two different intellectual starting points to analyze academic communities as cultural entities: studies of disciplinary cultures and institutional cultures. Notions of disciplines as cultural entities have been developed in Europe in relation to the “two cultures” topic and to issues developed in the sociology of knowledge. The institutional studies tradition is, in turn, rooted in the American intellectual tradition, where cultural concerns emerge from institutional level phenomena whether they concern students, faculty or higher education institutions. The article discusses the pros and cons of these traditions in order to find new avenues for future research. It will be argued that academic identity provides a seminal perspective for cultural studies in higher education.

Baculovirus-mediated periadventitial gene transfer to rabbit carotid artery.

Abstract: Recombinant Autographa californica multiple nuclear polyhedrosis viruses (AcMNPV) have recently been shown to transduce mammalian cells in vitro. Since baculoviruses offer many advantages over viruses currently used in gene therapy, we have tested them for in vivo gene transfer by constructing a baculovirus bearing a nuclear targeted beta-galactosidase marker gene (LacZ) under a CMV promoter. Both rabbit aortic smooth muscle cells (RAASMC) and human ECV-304 cells were susceptible to LacZ-baculovirus transduction. Transgene expression was evaluated in vivo by applying 1 x 10(9) p.f.u. of LacZ-baculoviruses or LacZ-adenoviruses in a silastic collar placed around rabbit carotid arteries in the absence of contact with blood components. As a result, baculoviruses led to transgene expression in adventitial cells in rabbit carotid arteries with efficiency comparable to adenoviruses. The beta-galactosidase gene expression was transient staying at a high level for 1 week but disappearing at the 14 day time-point. The arterial structure and endothelium remained intact in the baculovirus-transduced arteries, but macrophage-specific immunostaining detected signs of inflammation comparable to adenoviruses. Baculoviruses are thus able to mediate transient gene transfer in vivo and may become useful tools for gene therapy.

HE-LHC : The High-Energy Large Hadron Collider Future Circular Collider Conceptual Design Report Volume 4

Abstract: In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider (FCC-hh), a highest-luminosity high-energy lepton collider (FCC-ee), the corresponding 100 km tunnel infrastructure, as well as the physics opportunities of these two colliders, and a high-energy LHC, based on FCC-hh technology. This document constitutes the third volume of the FCC Conceptual Design Report, devoted to the hadron collider FCC-hh. It summarizes the FCC-hh physics discovery opportunities, presents the FCC-hh accelerator design, performance reach, and staged operation plan, discusses the underlying technologies, the civil engineering and technical infrastructure, and also sketches a possible implementation. Combining ingredients from the Large Hadron Collider (LHC), the high-luminosity LHC upgrade and adding novel technologies and approaches, the FCC-hh design aims at significantly extending the energy frontier to 100 TeV. Its unprecedented centre-of-mass collision energy will make the FCC-hh a unique instrument to explore physics beyond the Standard Model, offering great direct sensitivity to new physics and discoveries.
