    Projektin tarkoituksena oli toteuttaa neljä viriketuokiota Lohipuron ja Hopeapuron ikääntyneille asukkaille. Virikemuotoina käytettiin liikuntaa, musiikkia ja tietovisaa. Tavoitteena oli asukkaiden toimintakyvyn ylläpitäminen ja edistäminen sekä tuottaa mallit viriketuokioista palvelutalon käyttöön. Projekti aloitettiin syksyllä 2015. Viriketuokiot pidettiin 13.- ja 14. helmikuuta 2016. Viriketuokiot järjestettiin Lohipuron ruokasalissa ja Hopeapuron päiväsalissa. Yksi viriketuokio kesti aina 15 minuuttia ja ne toteutettiin iltapäivällä. Viriketuokioita oli kaksi päivää kohden. Liikuntaviriketuokiot sisälsivät tuolijumppaa erilaisin jalkaliik-kein ja käsiliikkein. Tietovisaviriketuokiot sisälsivät tietovisan, jossa oli myös mu-siikkiin liittyviä kysymyksiä. Viriketuokioista saatu palaute koottiin haastattelemalla osallistujia arviointilomakkeen kysymysten avulla. Hoitajilta arviointi koottiin sekä suullisella että arviointilo-makkeen avulla. Viriketuokioihin osallistuneiden ikääntyneiden ja hoitajien palaute oli erittäin positiivista. Molemmat viriketuokiot olivat pidettyjä sekä Lohipurossa että Hopeapurossa. Viriketuokiot koettiin hyvin viihdyttäviksi ja virkistäviksi. Viri-ketuokioiden koettiin tuovan myös paljon iloa. Lohipuron ja Hopeapuron asukkaat osallistuisivat viriketuokioihin uudelleen. Kumpikin hoitoyksikkö otti viriketuokio-mallit käyttöönsä. Jatkotutkimusaiheena voitaisiin selvittää kuinka paljon virike-tuokioita toteutetaan ikääntyneiden hoitoyksiköissä ja millainen vaikutus niillä on ikääntyneiden asukkaiden toimintakykyyn ja hyvinvointiin.The purpose of this thesis was to carry out four activity events for the elderly people in the nursing home of Lohipuro and Hopeapuro. As activities, exercise, music and quiz. The objectives for the activity event were to improve and maintain ability to function as well as produce models of the activity events for the use of nursing home. This thesis was started during autumn of 2015. Activity events took place 13th and 14th of February 2016. Activity events were arranged in the ballroom of the nursing home of Lohipuro and Hopeapuro. One activity event lasted 15 minutes and took place in afternoon. Exercise activities included chair exercise practice with various foot movements and hand movements. Quiz activities included quizlet, which included also guestions of music. Feedback of the events were gathered by using feedback temple`s question during participant interviews. Nurses also gave feedback both in written and verbally. Received feedback were very positive. Experiences of events were very braicing and entertainment. Events bring a lot of joy for the elderly people. Elderly people wants to take part in events again. Elderly people liked both of the events. Produce models of activities to use of nursing home were wanted. Both of the nursing units take willing produce models of the activity for their use. As a further studies may be presented explain how much activity events arrange in the elderly people nursing units and how it affect for the elderly people´s ability of function and their well-being

    Search for low lying dipole strength in the neutron rich nucleus 26^{26}Ne

    Coulomb excitation of the exotic neutron-rich nucleus 26^{26}Ne on a nat^{nat}Pb target was measured at 58 A.MeV in order to search for low-lying E1 strength above the neutron emission threshold. Data were also taken on an nat^{nat}Al target to estimate the nuclear contribution. The radioactive beam was produced by fragmentation of a 95 A.MeV 40^{40}Ar beam delivered by the RIKEN Research Facility. The set-up included a NaI gamma-ray array, a charged fragment hodoscope and a neutron wall. Using the invariant mass method in the 25^{25}Ne+n channel, we observe a sizable amount of E1 strength between 6 and 10 MeV. The reconstructed 26^{26}Ne angular distribution confirms its E1 nature. A reduced dipole transition probability of B(E1)=0.49±\pm0.16 e2fm2e^2fm^2 is deduced. For the first time, the decay pattern of low-lying strength in a neutron-rich nucleus is obtained. The results are discussed in terms of a pygmy resonance centered around 9 MeV

    SD electronics: simulations on the dynamic range

    Get PDF
    The surface detector electronics of the Pierre Auger Observatory is characterized by a large dynamic range due to the variation of the signal intensity of the Cherenkov tanks as a function of the distance from the core. In this paper, we present results of simulations and discuss the impact of the dynamic range on the shower reconstruction

    Centaurus A at Ultra-High Energies

    Full text link
    We review the importance of Centaurus A in high energy astrophysics as a nearby object with many of the properties expected of a major source of very high energy cosmic rays and gamma-rays. We examine observational techniques and the results so far obtained in the energy range from 200 GeV to above 100 EeV and attempt to fit those data with expectations of Centaurus A as an astrophysical source from VHE to UHE energies.Comment: 11 pages, 4 figures, accepted for publication in PAS

    Design of the photomultiplier bases for the surface detectors of the Pierre Auger Observatory

    Get PDF
    The design of the photomultiplier bases for the surface detectors of the Pierre Auger Observatory is presented. The bleeder is purely resistive. The base comprises two outputs: one from the anode and another one from the last dynode followed by an amplifier. The charge ratio between the anode and the amplified dynode is around 30. The design ensures a low consumption (less than 100 mu A at 2 kV), a stability of the gain and of the base line during the whole period of measurement (20 mu s per event) and for the whole dynamic range (max. 1 to 3x10^4 in amplitude). First measurement with a prototype base on the Hamamatsu R5912 photomultiplier tube are presented

    Processing of the Signals from the Surface Detectors of the Pierre Auger Observatory

    Get PDF
    Abstract The detectors of the surface array of the Pierre Auger Observatory are water Cherenkov tanks. The signals from each tank are read out using three photomultipliers. The energy of the primary particle is inferred from signal densities and requires good linearity of the PMTs and a large dynamic range. The absolute time of arrival of the shower front at each tank is obtained from the Global Positioning System (GPS) with a resolution of about 10 ns, ensuring an accurate primary angular reconstruction. Additionally, it is intended to use the rise time and shape of the signals to constrain the nature of the primary particle: this sets further requirements on the signal processing. In this paper, the main features of the signal processing associated with the surface detector will be presented and its performance will be discussed in the context of the extraction of shower parameters

    Interfering Doorway States and Giant Resonances. II: Transition Strengths

    Get PDF
    The mixing of the doorway components of a giant resonance (GR) due to the interaction via common decay channels influences significantly the distribution of the multipole strength and the energy spectrum of the decay products of the GR. The concept of the partial widths of a GR becomes ambiguous when the mixing is strong. In this case, the partial widths determined in terms of the KK- and SS-matrices must be distinguished. The photoemission turns out to be most sensitive to the overlapping of the doorway states. At high excitation energies, the interference between the doorway states leads to a restructuring towards lower energies and apparent quenching of the dipole strength.Comment: 17 pages, LaTeX, 5 figures as JPEG, to appear in PRC (July 1997

    Compilation of Giant Electric Dipole Resonances Built on Excited States

    Get PDF
    Giant Electric Dipole Resonance (GDR) parameters for gamma decay to excited states with finite spin and temperature are compiled. Over 100 original works have been reviewed and from some 70 of which more than 300 parameter sets of hot GDR parameters for different isotopes, excitation energies, and spin regions have been extracted. All parameter sets have been brought onto a common footing by calculating the equivalent Lorentzian parameters. The current compilation is complementary to an earlier compilation by Samuel S. Dietrich and Barry L. Berman (At. Data Nucl. Data Tables 38(1988)199-338) on ground-state photo-neutron and photo-absorption cross sections and their Lorentzian parameters. A comparison of the two may help shed light on the evolution of GDR parameters with temperature and spin. The present compilation is current as of January 2006.Comment: 31 pages including 1 tabl

    Probing the 6He halo structure with elastic and inelastic proton scattering

    Full text link
    Proton elastic scattering and inelastic scattering to the first excited state of 6He have been measured over a wide angular range using a 40.9A MeV 6He beam. The data have been analyzed with a fully microscopic model of proton-nucleus scattering using 6He wave functions generated from large space shell model calculations. The inelastic scattering data show a remarkable sensitivity to the halo structure of 6He.Comment: 9 pages, 3 figures. RevTeX. Replaced figure 3 with updated figur

    Chaotic Scattering in Heavy--Ion Reactions

    Get PDF
    We discuss the relevance of chaotic scattering in heavy--ion reactions at energies around the Coulomb barrier. A model in two and three dimensions which takes into account rotational degrees of freedom is discussed both classically and quantum-mechanically. The typical chaotic features found in this description of heavy-ion collisions are connected with the anomalous behaviour of several experimental data.Comment: 35 pages in RevTex (version 3.0) plus 27 PostScript figures obtainable by anonymous ftp from VAXFCT.CT.INFN.IT in directory kaos.
