Die Wirkung von Cyproheptadin auf die Winterschlafbereitschaft und die jahreszeitlichen Körpergewichtsänderungen beim sibirischen BackenhörnchenTamia…

1971

The effect of cyproheptadin (4 mg/kg per os) on the typical weight cycle of sibirian chipmunksTamias (Eutamias)sibiricus before and during the hibernation period was studied. The substance leads to a complete inhibition of hibernation and the bodyweight reaches a lower level than in control animals.

Direkte Dickenmessung an Muskelstreifenpräparaten und Gewebsschnitten

1967

An apparatus for direct measurement of the thickness of tissue slices and muscle strips is described. Micrometer callipers are used, the proper adjustment of which is indicated by the sudden scale deflection of an ohmmeter. In comparison with the method of calculation based on a measurement of the area of the slice, this technique is time-saving and the results are more accurate and reproducible.

Serologisch-hämatologische und immunologische Untersuchungen an winterschlafenden Fledermäusen (Myotis myotis S.)

1963

Antibody deficiency in hibernating bats (Myotis myotis S.) was shown by precipitin reaction. Theγ-globulins in serum of hibernating bats decreased to one half of the normal value. There is significant leukopenia, lymphopenia and eosinopenia. Injected bovine albumin was completely removed within 9 days in active animals, in torpid animals only 1/25 was absorbed from the 6th to the 23rd day.

Preparation of serum for paper electrophoresis from small animals

1963

1 bis 2 Tropfen Blut werden in einer Kapillare 10 min bei 10 000 U/min zentrifugiert. Die Kapillare wird an der Schichtgrenze zerschnitten. Das Serum kann so leicht auf die Papierstreifen zur Elektrophorese aufgetragen werden.

Measurement of the mass and lifetime of the Ω(−)(b) baryon

2016

A proton-proton collision data sample, corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at $\sqrt{s}=7$ and 8 TeV, is used to reconstruct $63\pm9$ $\Omega_b^-\to\Omega_c^0\pi^-$, $\Omega_c^0\to pK^-K^-\pi^+$ decays. Using the $\Xi_b^-\to\Xi_c^0\pi^-$, $\Xi_c^0\to pK^-K^-\pi^+$ decay mode for calibration, the lifetime ratio and absolute lifetime of the $\Omega_b^-$ baryon are measured to be \begin{align*} \frac{\tau_{\Omega_b^-}}{\tau_{\Xi_b^-}} &= 1.11\pm0.16\pm0.03, \\ \tau_{\Omega_b^-} &= 1.78\pm0.26\pm0.05\pm0.06~{\rm ps}, \end{align*} where the uncertainties are statistical, systematic and from the calibration mode (for $\tau_{\Omega_b^-}$ only).
