    Notes: An analysis of the coherent states for the noncompact supergroup Osp(2/2N,R) is presented. In contrast to Osp(1/2N,R), both typical and atypical representations have to be considered. The measure of integration, in general, for Osp(2/2N,R) coherent states is calculated; it is then used to construct the decomposition of unity for the special case of Osp(2/2,R). It is found, however, that the typical and atypical representations of Osp(2/2,R) have to be treated separately. It is verified that the coherent states for Osp(2/2,R) are "closest to classical'' in the sense of Perelomov.

    Notes: Some physically realizable positive discrete series representations of the noncompact orthosymplectic superalgebra Osp(4/2,R) are considered. The decomposition of these Osp(4/2,R) representations on reduction to Sp(2,R)×SO(4) is studied in detail, and the corresponding state vectors are explicitly constructed by acting with the generators on a general lowest weight state. Some examples are given to illustrate these results for particular single-particle spaces.

    Notes: Coherent states for the harmonic oscillator representations of the noncompact supergroup Osp(1/2N,R) are introduced and the invariant integration measure is calculated by studying transformation properties of supercoset variables. The generalized Bogoliubov transformation for mixed systems of bosons and fermions is also obtained. An example for the simple harmonic oscillator is given.

    Notes: 1. Dibutyryl cyclic AMP (Db CAMP, 75–500 μg/kg), injected into the lateral ventricle of the brain of the cat increased blood pressure, heart rate and splanchnic discharge rate.2. ATP, but not AMP, induced similar changes; GMP in small doses increased blood pressure.3. A number of drugs are known to activate adenylate cyclase-induced hypertension, tachycardia and increase splanchnic discharge rate. This was shown for TRH, tetracosactide and a new β2-adrenoceptor stimulant, NAB 365.4. Injection into the lateral ventricle of theophylline or Ro 7/ 2956, both inhibitors of phosphodiesterase, similarly increased blood pressure.5. Histamine administered by the same route induced similar reactions; it is not known if this action was exerted by activation of H1- or H2-receptors.6. Somatostatin, known to reduce cAMP levels, induced a small but significant decrease in blood pressure. Melanocyte stimulating hormone release inhibiting factor (MIF) and TSH were ineffective.7. These results provide evidence for the possibility of a role for cAMP in the central regulation of blood pressure at suprabulbar levels.

    Notes: Abstract The heavy liquid bubble chamber, Gargamelle, has been used to investigate the gross features of the annihilation of antineutrons in light nuclei (mainly Carbon). Results are presented on the distributions of multiplicity, momentum and emission angle for charged pions and protons together with a simple model to describe them.

    Notes: Abstract Theβ-ray spectrum of Cs137 has been measured with an iron-free spectrometer. The energy of the soft component was found to beE 0=514±2 keV. The parameterk of the hard-component shape factorC 2VA (2) (W)=q 2+kp 2 was determined to bek=0.015±0.004. Theβ intensities amount to 6.5% (hard component) and 93.5% (soft component). TheK conversion coefficient of the isomeric transition was measured to beα K=0.093±0.003, in excellent agreement withSliv's theoretical value.

    Notes: Abstract In the decay Eu152→Gd152 fiveβ(circularly polarizedγ) correlations have been measured (Table). The Fermi matrix element of the 3−–3− β transition is small or vanishing. The levels of 344 and 755 keV (I=2+ and 4+, respectively) seem to be collective states.

    Notes: Summary The blood pressure is not disturbed by a local injection of norepinephrine into the hypothalamus, but the excitability of vasopressor centres is affected. Often, the excitability of these centres is decreased; sometimes, it is increased, and, more rarely, it is first potentiated and then inhibited. Epinephrine has the same action, but dopamine is less potent; isoprenaline produces both facilitation and inhibition of these centres, but the facilitating effect is more frequent than with norepinephrine.

    Notes: Summary In dogs, anaesthetized with chloralose, fentanyl (5 μg/kg i.v.) augmented the bradycardia produced by electrical stimulation of the carotid sinus nerves. In contrast, the same dose of the drug did not change the bradycardic response to stimulation of the nucleus of the solitary tract (NTS) indicating that a central facilitation of baroreceptor impulses occurs within the NTS, probably at the first synapse of baroreceptor reflex fibres. Bilateral destruction of the NTS caused a ful-minating hypertension and tachycardia similar to that after cutting the baroreceptor afferent fibres. After both procedures, fentanyl (20 μg/kg i.v.) produced marked hypotension and bradycardia. The bradycardic effect was abolished by cutting both vagal nerves when the dogs were pretreated with a β-adrenoceptor blocking agent (S 2395, 50 μg/kg i.v.). The results provide evidence that the NTS is not the main site of action either for the hypotensive effect or for the vagally mediated bradycardia of fentanyl. Since the dorsal nucleus of the vagal nerve was destroyed together with the NTS, this nucleus does also not appear to be a major site of the action of fentanyl. Blockade of dopamine receptors by haloperidol or pimozide or of serotonin receptors by methysergide did not change the hypotensive, bradycardic and sympathoinhibitory effects of fentanyl.
