    Canine leishmaniasis in the Gargano promontory (Apulia, South Italy) (1992)
    Springer
    European journal of epidemiology 8 (1992), S. 273-276 
    Details
    ISSN: 1573-7284

    Thema: Medizin
    Notizen: Abstract We examined 444 dogs by visiting farms and peripheral districts on the Gargano promontory (Province of Foggia, Apulia, South Italy). Clinical examination and immunofluorescence antibody test for leishmaniasis were performed. Bone marrow and lymph node samples obtained from 25 dogs with positive serological test were cultured on Tobie-Evans medium. The results obtained show both a higher seropositivity rate for canine leishmaniasis (14.4%) and a higher percentage of asymptomatic dogs with positive serological test (53.1%) compared to previous research in the same area. Seven strains isolated from infected dogs belonged to Leishmania infantum species zymodeme Montpellier 1. None of 82 sera of humans living in close contact with infected dogs were positive for leishmaniasis.

    Frequency measurements of far infrared laser lines by means of MIM point contact diodes (1994)
    Springer
    International journal of infrared and millimeter waves 15 (1994), S. 1347-1360 
    Details
    ISSN: 1572-9559
    Schlagwort(e): methanol ; Far Infrared laser ; frequency measurement
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract We present frequency measurements of 85 Far Infrared (FIR) laser lines ranging from 2 748 GHz to 421 GHz. We use the heterodyne technique of mixing FIR laser transitions and microwave radiation on MIM point contact diodes to determine the FIR frequencies.

    Optical properties of YBaCuO thin films at Far-Infrared monochromatic light (1995)
    Springer
    International journal of infrared and millimeter waves 16 (1995), S. 1189-1199 
    Details
    ISSN: 1572-9559
    Schlagwort(e): YBaCuO ; MgO ; Far-Infrared ; reflectivity ; transmission ; losses ; damage-diagnostic
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract By using monochromatic sources of radiation we measured the reflectivity and transmission vs temperature behavior of YBaCuO thin film in the Far Infrared region in the range 300-20 K. A smooth change of optical properties is observed from critical temperature down to 40 K with an evident reduction of the losses for all the frequencies we examined. To analyze the use of YBaCuO films as semireflecting elements in submillimeter devices we made a preliminary study of the optical properties of the substrate in the same conditions. The permanence of the sample in a superconducting phase can be deduced from its room-temperature transmittance, as it changes drastically if some degeneracy occurs in the film.

    Assignments of methanol laser lines by frequency measurements and Fourier transform spectroscopy (1994)
    Springer
    International journal of infrared and millimeter waves 15 (1994), S. 619-633 
    Details
    ISSN: 1572-9559
    Schlagwort(e): methanol ; FIR laser ; frequency measurement
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract We have measured the frequencies of four CH3OH far-infrared laser lines that were previously known only by wavelength measurement. Two of these lines turned out to be doublets, bringing the total number of measured lines to six. We can now confirm the assignments of five of them and definitely disprove the assignments proposed for the sixth. In particular we confirm the assignments for the four strong laser lines at 205 and 208 µm pumped by the 9-P(34) CO2 laser line. These lines share a common upper level in the first excited CO-stretch state, and terminate in the upper and lower levels of a hybrid state with J=5. Heterodyne frequency measurements and conventional microwave spectroscopy show that both lines are split into two components approximately 3.5 MHz apart. The origin of this further splitting is interpreted as a perturbed K-splitting.

    Electric field effects on roto-vibrational transitions of13CD3OH1 (1995)
    Springer
    International journal of infrared and millimeter waves 16 (1995), S. 2233-2248 
    Details
    ISSN: 1572-9559
    Schlagwort(e): Stark spectroscopy ; Far Infrared laser ; methanol

    Thema: Physik
    Notizen: Abstract We used a Stark-Optoacoustic cell and hybrid waveguide resonators to perform an Infrared and Far Infrared Stark Spectroscopy study on some transitions of13CD3OH. Different behaviours of the transitions in the presence of a d.c. electric field were observed. The Stark splittings of six FIR laser lines ranging from 34 to 136 MHz/kVcm−1 were determined. The analysis of the behaviour of the IR and FIR transitions in the presence of the external electric fields gives important and exclusive information on the levels involved in the transitions.
