Status of Evidence for Neutrinoless Double Beta Decay

The present experimental status in the search for neutrinoless double beta decay is reviewed, with emphasis on the first indication for neutrinoless double beta decay found in the Heidelberg-Moscow experiment, giving first evidence for lepton number violation and a Majorana nature of the neutrinos. Future perspectives of the field are briefly outlined.Comment: 37 pages, latex, 23 figures, Published in Found.

A new and little known species of the genus Aspistes Meigen (Diptera, Scatopsidae) from Finland

Flies of the genus Aspistes Meigen from the collection of the Zoological Museum, University of Helsinki, Finland, (ZMH) have been revised. One new species, A. helleni sp.n., is described from Finland. Data on the morphology and the distribution of A. freyi Cook are given, including the description of the female. A key to the Palaearctic species of the genus Aspistes Meigen is presented

Search for neutrinoless double beta decay with enriched 76Ge in Gran Sasso 1990-2003

The results of the HEIDELBERG-MOSCOW experiment which searches with 11 kg of enriched 76Ge for double beta decay in the GRAN Sasso underground laboratory are presented for the full running period August 1990 - May 2003. The duty cycle of the experiment was ~80%, the collected statistics is 71.7 kg y. The background achieved in the energy region of the Q value for double beta decay is 0.11 events/ kg y keV. The two-neutrino accompanied half-life is determined on the basis of more than 100 000 events. The confidence level for the neutrinoless signal has been improved to 4.2 sigma.Comment: 19 pages, latex, 9 figures, 2 table

The Palaearctic species of the genus Sylvicola Harris, 1776 (Diptera, Anisopodidae).

Die Beschreibungen für 9 bisher bekannte paläarktische Arten von Sylvicola Harris werden präzisiert. Auf der Basis von Exemplaren, die in der Vergangenheit als S. fuscatus (Fabricius) bestimmt wurden, werden mit S. subfuscatus spec. nov. und S. stackelbergi spec. nov. zwei neue Arten beschrieben. Für alle paläarktischen Spezies wird eine Bestimmungstabelle gegeben.Nomenklatorische Handlungenstackelbergi Krivosheina & Menzel, 1998 (Sylvicola (Anisopus)), spec. n.subfuscatus Krivosheina & Menzel, 1998 (Sylvicola (Anisopus)), spec. n.The descriptions of the 9 previously known Palaearctic species of Sylvicola Harris are revised, 2 new species close to S. fuscatus (Fabricius) [S. subfuscatus spec. nov. and S. stackelbergi spec. nov.] are described.

Measurement of the 214Bi spectrum in the energy region around the Q-value of 76Ge neutrinoless double-beta decay

In this work we present the results obtained measuring the 214Bi spectrum from a 226Ra source with a high purity germanium detector. Our attention was mostly focused on the energy region around the Q-value of 76Ge neutrinoless double-beta decay (2039.006 keV). The results of this measurement are strongly related to the first indication for the neutrinoless double beta decay of 76Ge, given by a recent analysis \cite{Evidence,KK02-PN,KK02-Found,KK-BigArt02} of the data collected during ten years of measurements from the HEIDELBERG-MOSCOW experiment.Comment: 10 pages, latex2e, 5 figures, see also Home Page of HEIDELBERG Non-Accelerator Particle Physics Group: http://www.mpi-hd.mpg.de/non_acc

First Results from the HDMS experiment in the Final Setup

The Heidelberg Dark Matter Search (HDMS) is an experiment designed for the search for WIMP dark matter. It is using a special configuration of Ge detectors, to efficiently reduce the background in the low-energy region below 100 keV. After one year of running the HDMS detector prototype in the Gran Sasso Underground Laboratory, the inner crystal of the detector has been replaced with a HPGe crystal of enriched $^{73}$Ge. The final setup started data taking in Gran Sasso in August 2000. The performance and the first results of the measurement with the final setup are discussed.Comment: 8 pages, revtex, 7 figures, Home Page of Heidelberg Non-Accelerator Particle Physics Group: http://www.mpi-hd.mpg.de/non_acc

To the knowledge of insects, pollinators of Sorbus aucuparia Linnaeus, 1753 and Aronia mitschurinii A.K. Skvortsov et Maitul., 1982 in Moscow Region, Russia

Composition of insect species pollinating Sorbus aucuparia and Aronia mitschurinii in Moscow Region, Russia was studied. It was collected 39 species – representatives of 4 orders and 21 families. The hypothesis that these two plants with same inflorescences and blossoming simultaneously are visited by the same insect species was not proved: 18 species were captured only on S. aucuparia and 16 species only on A. mitschurinii. Insects demonstrated selectivity towards aboriginal (Sorbus) and adventive (Aronia) plants. Only five species were registered on both plants: Bombus ruderarius Müller, 1776, Andrena haemorrhoa (Fabricius, 1781), Bellardia viarum obineauDesvoidy, 1830, Anthrenus scrophulariae Linnaeus, 1758 and Anaspis frontalis (Linnaeus, 1758). Sorbus aucuparia was more attractive for Diptera from the families Calliphoridae and Milichiidae, and Aronia mitschurinii – for Anthomyiidae, Calliphoridae and Sarcophagidae. Selectivity was discovered at species level also: Andrena ruficrus Nylander, 1848 and Myopa polystigma Rondani, 1857 visited Aronia mitschurinii only and Andrena subopaca Nylander, 1848 and Myopa testacea (Linnaeus, 1767) – Sorbus aucuparia. The majority of collected insect species are polyphagous. Additional data on other plants visited by the same insects during the period of bloom of Sorbus and Aronia are given, including those from the genera Malus, Spiraea, Pyrus, Prunus, Rosa, Rubus, Cerasus Crataegus, Barbarea and Taraxacum

New data on morphology and biology of soldier flies Adoxomyia cinerascens (Loew, 1873) and A. heminopla (Wiedemann, 1819) (Diptera: Stratiomyidae)

Imaginal characters of Palaearctic species of Adoxomyia cinerascens (Loew, 1873) and Oriental species of A. heminopla (Wiedemann, 1819) are improved. The morphology and biology on larva of Adoxomyia cinerascens with additional data on larva of A. heminopla are studied for the first time. Imago are well distinguished by the structure of antennae, pollination of frons and position of spines on scutellum, larvae by the structure of integument and the topography of seta
