    Bhabha to Møller cross section ratios in the energy range 2.15–2.45 MeV (1993)

    Notes: Abstract The cross sections for Bhabha and Møller scattering have been investigated in the energy range 2.1–2.4 MeV using monoenergetic positrons and electrons to search for hypothetical resonances superimposed to the continuum predicted by quantum electro dynamics. Bhabba-to-Mott, Møller-to-Mott and Møller-to-Bhabha cross section ratios were measured. The Bhabha-to-Mott ratios could be determined with statistical errors of typically 1% and remaining systematic errors not exceeding the statistical ones. No resonances in Bhabha scattering were observed. Limits for the intrinsic widths of hypothetical resonances are given. For the first time upper limits are deduced from our data for hypothetical resonances in the Møller scattering cross section in the MeV range. Additionally, Møller-to-Bhabha cross section ratios could be determined with good precision. A good agreement between the experimental and theoretical Møller-to-Bhabha ratios can be stated calling in question the recently predicted existence of series of narrow, unresolvable resonances in the Bhabha scattering cross section.

    Thermogenic effects of thyrotrophin-releasing hormone and its analogues in the rat (1988)
    Springer

    Notes: Summary Acute or chronic injection of RX 77368 (a TRH analogue; 1 mg/kg s.c.) stimulated oxygen consumption (VO2) and brown adipose tissue activity in the rat, and decreased weight gain Other TRH analogues (CG 3509, RGH 2202) and TRH itself also stimulated VO2. These thermogenic actions are probably mediated centrally by stimulation of sympathetic outflow to brown fat.

    Stygofauna of the Canary Islands, 6 A new Rhipidogammarus (Crustacea, Amphipoda) from Tenerife: first record of the genus outside the Mediterranean region and its biogeographic implications (1988)

    Notes: Abstract The discovery of a new species ofRhipidogammarus, Rh. nivariae n. sp., in water supply shafts of Tenerife (Canary Islands), presents an interesting biogeographic problem. Up to now, members of the genus were known exclusively from stygohabitats in the peri-Mediterranean belt. Its sister-genus is found in very shallow waters of the Mediterranean, and on morphological grounds the genus seems to have got adapted only fairly recently to continental hypogean waters. The occurrence of a member ofRhipidogammarus on an oceanic island like Tenerife can be explained by one of the following two scenarios: (1) Tenerife is a fragment of the African plate, or (2) the island's volcanic outcrops arose from a very shallow submarine bank and drifted later into deeper waters.
