AbstractAbstract
[en] The Frascati Φ-factory DAΦNE has successfully completed experimental runs for the three main detectors, KLOE, FINUDA and DEAR. The best peak luminosity achieved so far is 1.6 × 1032 cm-2 s-1, while the best daily integrated luminosity is 10 pb-1. At present the DAΦNE team is preparing an upgrade of the collider based on the novel crab waist collision scheme. The upgrade is aimed at pushing the luminosity towards 1033cm-2s-1. In this paper we describe present collider performance and discuss ongoing preparatory work for the upgrade.

AbstractAbstract
[en] This paper discusses the techniques used to select online promising events at high energy and high luminosity colliders. After a brief introduction, explaining some general aspects of triggering, the more specific implementation options for well established machines like the Tevatron and Large Hadron Collider (LHC) are presented. An outlook on what difficulties need to be met is given when designing trigger systems at the Super Large Hadron Collider, or at the International Linear Collider

AbstractAbstract
[en] The concept of 'Sequences' of early-type galaxies has been introduced to describe the magnitude Bsub(T) effective radius Asub(e) relation in clusters, according to the definitions and data in the Second Reference Catalogue of Bright Galaxies. For Main Sequence objects, a formula involving the average brightness msub(e) within Asub(e) and the color U-B (or U-V) can be used to estimate relative luminosities and distances of E-SO galaxies

AbstractAbstract
[en] Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadron and electron machines. They should thus be regarded as complementary. Parameters are given of 4 TeV and 0.5 TeV high luminosity μ+μ- colliders, and of a 0.5 TeV lower luminosity demonstration machine. We discuss the various systems in such muon colliders, starting from the proton accelerator needed to generate the muons and proceeding through muon cooling, acceleration and storage in a collider ring. Detector background, polarization, and nonstandard operating conditions are discussed

AbstractAbstract
[en] The Fermilab accelerator complex is in the middle of a major upgrade to increase the luminosity beyond the original design goal. During Phase I of this upgrade, there have been major modifications to the Tevatron. These modifications were commissioned at the start of the latest collider run and include the installation of electrostatic separators to separate the orbits of the stored beams and new low beta insertions to squeeze the colliding proton and antiproton beams at both experiment interaction regions. These modifications have already enabled the Tevatron to achieve a record peak luminosity of 6.93 x 10"3"0 per sq cm per s and a record weekly integrated luminosity of 10"6"0 inverse nanobarns. The peak goal for the present run of 5.0 x 10"3"0 has already been exceeded

AbstractAbstract
[en] Absolute magnitudes of Ba II stars determined from the width of Hα indicate that these stars have, on the average, the luminosity of normal G and K giants. There may, however, be some Ba stars of luminosity class IV. The distribution of stars in absolute magnitude does not seem to depend on Ba line strength. (3 figs, 10 refs) (auth)

AbstractAbstract
[en] The stellar spectroscopy laboratory is the flagship of a wide-ranging work of curriculum counselling fostered by the Physics Department of the Milan University and the high school 'G. Parini' in Milan. In time, valuable results were gained in setting up a new way of collaboration between the high school and university worlds and in spurring secondary-school students to embark in a scientific, and more specifically physical, career. The present work briefly discusses the contents of the laboratory, its didactical value, its role of curriculum counselling and its effectiveness in directing students to take into consideration the physical sciences as a possible university choice.
