    Fleas were collected from mammals during the period 1990-1992 in two upper peninsula counties. Identified specimens were compared to existing distribution records for both parasite and host. Only those records which are newly documented for county, upper peninsula or Michigan are listed. We report one previously unknown flea species and five new host records for Michigan. One host record is new for the upper peninsula. In addition, seven new host/parasite combinations are recorded for two central upper peninsula counties

    Fleas were collected from birds and mammals over a five year period in four upper peninsula counties. Identified specimens were compared to published records of distribution for the parasite species and its host species, and only those records which are new county distributions for host or parasite are listed. Four new host records for Michigan, four new flea distribution records for the upper peninsula, and 26 new county records are listed

To do this, we studied social well-being indicators and analyze the environmental situation in g. Yurga

    Optical Spectroscopy of IRAS 02091+6333

    We present a detailed spectroscopic investigation, spanning four winters, of the asymptotic giant branch (AGB) star IRAS 02091+6333. Zijlstra & Weinberger (2002) found a giant wall of dust around this star and modelled this unique phenomenon. However their work suffered from the quality of the optical investigations of the central object. Our spectroscopic investigation allowed us to define the spectral type and the interstellar foreground extinction more precisely. Accurate multi band photometry was carried out. This provides us with the possibility to derive the physical parameters of the system. The measurements presented here suggest a weak irregular photometric variability of the target, while there is no evidence of a spectroscopic variability over the last four years.Comment: 5 pages, Latex, 3 tables, 4 figures, Astron. & Astrophys. - in pres

    Nuclear magnetic resonance measurements reveal the origin of the Debye process in monohydroxy alcohols

    Full text link
    Monohydroxy alcohols show a structural relaxation and at longer time scales a Debye-type dielectric peak. From spin-lattice relaxation experiments using different nuclear probes an intermediate, slower-than-structural dynamics is identified for n-butanol. Based on these findings and on diffusion measurements, a model of self-restructuring, transient chains is proposed. The model is demonstrated to explain consistently the so far puzzling observations made for this class of hydrogen-bonded glass forming liquids.Comment: 4 pages, 4 figure
