Keep Calm and Cope On: How Families Cope with Childhood Cancer

The purpose of the current study was to examine how childhood cancer affects the family system after a period of time (at least one year) has passed. A questionnaire was developed by the author and given to families that were recruited through a snowball sampling procedure. The final sample consisted of 17 families in various stages of coping after a child in the family was diagnosed with cancer. Findings showed that overall, the women in the study tended to cope in more positive ways than men, that siblings often reported to their parents that they felt excluded and can experience emotional and behavioral issues long after the cancer diagnosis, and that family roles are threatened when families are dealing with cancer

First results with the ORPHEUS dark matter detector

The ORPHEUS dark matter detector is operating at our underground laboratory in Bern (70 m.w.e.). The detector relies on measuring the magnetic flux variation produced by weakly interacting massive particles (WIMPs) as they heat micron-sized superheated superconducting tin granules (SSG) and induce superconducting-to-normal phase transitions. In an initial phase, 0.45 kg of tin granules in a segmented detector volume have been used. In this paper a general description of the experimental set-up, overall performance of the detector, and first results are presented.Comment: 20 pages, Latex, submitted to Astropart. Phy

Nuclear recoil measurements in Superheated Superconducting Granule detectors

The response of Superheated Superconducting Granule (SSG) devices to nuclear recoils has been explored by irradiating SSG detectors with a 70Me$\!$V neutron beam. In the past we have tested Al SSG and more recently, measurements have been performed with Sn and Zn detectors. The aim of the experiments was to test the sensitivity of SSG detectors to recoil energies down to a few ke$\!$V. In this paper, the preliminary results of the neutron irradiation of a SSG detector made of Sn granules 15-20$\mu$m in diameter will be discussed. For the first time, recoil energy thresholds of $\sim$1ke$\!$V have been measured.Comment: 7pages in Latex format, Preprint Bu-He 93/6 (University of Berne, Switzerland), four figures available upon request via [email protected] or [email protected]

Completion of a city block Urban development study of a city block between the streets Koliště, Cejl a Vlhká

Takto velkých zastavitelných parcel v centru v Brna už moc není, navíc je parcela umístěná těsně za bývalým hradebním pásem, jehož stopa je v uliční síti čitelná dodnes, a do současností stanoví jakousi bariéru - citelné rozmezí centra a širšího centra Brna. Úkol byl tedy výzvou, jak rozvinout město a jeho centrum, aby prorostlo do okolí a zahustilo jej při zachování jeho kvalit. Možná je otázkou, zda je potřeba, aby město rostlo. Na to mám jednoduchou odpověď. Základní zákon přírody říká: co se nerozvíjí, umírá. Svůj stavební program jsem si zvolil a formy architektonického jazyka používám tak, abych vytvořil městotvornou zástavbu velkoměstského charakteru. Jakýsi městský palác se vším vybavením. Jako vzor si beru městské paláce v centru Brna, které jsou multifunkčními komplexy s parkováním, koncertními sály, pasážemi, obchody, kancelářemi, holičstvími, službami a bydlením vybaveným vším, co městský člověk dnes potřebuje.There is no large land plots in the center of Brno anymore, the plot is located just behind the former embankment, the trace of which is still legible in the street network, and to the present it establishes a certain barrier - the range of the center and the wider center of Brno. The task was therefore to develop the city and its center to penetrate the area and thaw it while preserving its qualities. Perhaps the question is whether there is a need for the city to grow. I have a simple answer to that. The basic Law of nature says: what does not develop, dies. I have chosen my building program and used architectonic forms to create a city-built urban development. A sort of city palace with all the equipment. As a model I took the city palaces in the center of Brno, which are multifunctional complexes with parking, concert halls, passages, shops, offices, barber shops, services and housing equipped with everything that an urban person needs today.

Light response of pure CsI calorimeter crystals painted with wavelength-shifting lacquer

We have measured scintillation properties of pure CsI crystals used in the shower calorimeter built for a precise determination of the pi+ -> pi0 e+ nu decay rate at the Paul Scherrer Institute (PSI). All 240 individual crystals painted with a special wavelength-shifting solution were examined in a custom-build detection apparatus (RASTA=radioactive source tomography apparatus) that uses a 137Cs radioactive gamma source, cosmic muons and a light emitting diode as complementary probes of the scintillator light response. We have extracted the total light output, axial light collection nonuniformities and timing responses of the individual CsI crystals. These results predict improved performance of the 3 pi sr PIBETA calorimeter due to the painted lateral surfaces of 240 CsI crystals. The wavelength-shifting paint treatment did not affect appreciably the total light output and timing resolution of our crystal sample. The predicted energy resolution for positrons and photons in the energy range of 10-100 MeV was nevertheless improved due to the more favorable axial light collection probability variation. We have compared simulated calorimeter ADC spectra due to 70 MeV positrons and photons with a Monte Carlo calculation of an ideal detector light response.Comment: Elsevier LaTeX, 35 pages in e-print format, 15 Postscript Figures and 4 Tables, also available at http://pibeta.phys.virginia.edu/~pibeta/subprojects/csipro/tomo/rasta.p

Limits on Neutrino Mixing with new Heavy Particles

We study the effects induced by new neutral fermions below their mass threshold, due to their possible mixing with the standard neutrinos. We use as experimental constraints the recent results on lepton universality, together with the measurement of the $\mu$ decay rate and the updated LEP data. In particular, the inclusion in our data set of the most recent determinations of the $\tau$ branching fractions, mass and lifetime implies that a previous indication of a non-vanishing mixing for $\nu_\tau$ is no longer present. We obtain new stringent limits on the mixing parameters between $\nu_e$, $\nu_\mu$, $\nu_\tau$ and heavy neutral states of different weak isospin. If no assumption on the type of neutrinos involved in the mixing is made, we find \snue^2<0.0071, \snumu^2<0.0014 and \snutau^2<0.033.Comment: 12 pages, FTUV/93-47, UM-TH-93-28, CERN-TH/7150/9

T-Odd Correlations in pi->e nu_e gamma and pi->mu nu_mu gamma Decays

The transverse lepton polarization asymmetry in pi_l2gamma decays may probe T-violating interactions beyond the Standard Model. Dalitz plot distributions of the expected effects are presented and compared to the contribution from the Standard Model final state interactions. We give an example of a phenomenologically viable model, where a considerable contribution to the transverse lepton polarization asymmetry arises.Comment: 19 pages, 5 figures.
