    Canine leishmaniasis in the Gargano promontory (Apulia, South Italy) (1992)

    Notes: 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
    Keywords: methanol ; Far Infrared laser ; frequency measurement

    Topics: Physics
    Notes: 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.

    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

    Notes: 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.
