    Notes: Representation of the nerves of the wings in the blue-fronted Amazon and the African grey parrot using a digital photographic techniqueIn four blue-fronted Amazon and five African grey parrots, the nerves innervating the muscles of the wings were carefully dissected and described. The preparation steps were recorded with a digital camera. This technique has now advanced so far that the image quality is almost the same as that of a normal camera. The pictures are stored in a computer. They can be enhanced and published via the Internet.

    Notes: Das Rettungszentrum der Medizinischen Hochschule Hannover gründet sich auf die gemeinsame Stationierung eines Rettungshubschraubers und eines Notarztwagens an der Medizinischen Hochschule mit einer mittlerweile 28-jährigen Erfahrung und insgesamt weit über 85.000 Einsätzen. Der Begriff Rettungszentrum steht aber auch insbesondere für die beispielhaft enge Anbindung der Rettungsmittel an die zentrale Notaufnahme der MHH. Gerade die präklinisch begonnene Versorgungskette darf bei der Übergabe des Patienten in der Notaufnahme nicht unterbrochen werden.

    Notes: Summary The organic matter and nitrogen contents of soils from cultivated lands were compared with those from adjacent veld sites at 0–30, 30–60, and 60–90 cm depths. At 0–30 cm depth the veld and adjacent cultivated soils did not differ much in organic matter and nitrogen contents. The largest differences were found at 60–90 cm depth, where the soils under cultivated lands contained considerably less organic matter and nitrogen than the veld soils. This was particularly evident in two sites at the Glen College of Agriculture and to a lesser degree in two sites in the Theunissen district where the soil was more sandy. The soil from the cultivated lands showed a marked decrease in organic matter and nitrogen contents and a distinct narrowing of the C : N ratio with increasing depth whereas the C- and N-contents and the C : N ratios of veld soils differed much less between depths. These results were explained by the soil moisture conditions prevailing under veld and cultivated lands during the course of the year. Judging from the decreases in organic matter and nitrogen contents since cultivation commenced, Central Orange Free State soils may vay considerably in the amounts of mineral nitrogen liberated following cultivation.

    Description / Table of Contents: The Alcotest 7110 Evidential MK III breath analyser calibrated and approved by PTB in Brunswick is a reliable instrument for measuring breath alcohol concentrations. The results obtained from experimental investigations of the variability of the blood alcohol-to-the breath alcohol ratio expressed by the quotient QBlAC/BrAC were basically identical to the theoretical calculations presented by Wehner et al. Based on the results obtained from experimental investigations to establish a factor for converting breath alcohol into blood alcohol concentrations, an opinion of the Bundesgesundheitsamt of 1992 indicated a blood alcohol to breath alcohol ratio of 2.098 ±0.11 rounded to 2.1 as proposed by Schoknecht [17]. The mean value established in the present paper from 455 sample pairs taken at the same time was 2.2. The maximum value was 3.29 and the minimum value was 0.74. The standard deviations were basically identical to the theoretical calculations of Wehner et al. [19]. Theoretically, the quotients established could be used as factors for converting breath alcohol into blood alcohol concentrations. However, due to large variability breath alcohol concentrations should not be converted into blood alcohol concentrations and vice versa in forensic opinions. This seems to be also true for the use of „transformed“ blood alcohol concentrations for back calculation to the time of offence and alleged after-drink. In particular, as a breath alcohol limit value relevant to criminal law cannot be calculated by a simple multiplication operation, solid research into the physiological and traffic-medical foundations as well as experiments are required to provide a reliable solution.
    Notes: Mit dem Alcotest 7110 Evidential MK III, durch die PTB in Braunschweig zugelassen und geeicht, steht ein hochwertiges Gerätesystem zur Messung der Alkoholkonzentration in der Ausatemluft zur Verfügung. Der Umrechnungsfaktor von Atem- in Blutalkoholkonzentrationen wurde von Schoknecht [17] im Gutachten des Bundesgesundheitsamtes 1992 experimentell als BAK/AAK-Quotient mit 2,098 ±0,11 bestimmt und auf 2,1 gerundet. Der Mittelwert von 455 zeitgleichen Wertepaaren der vorliegenden Arbeit lag bei 2,2. Der Maximalwert betrug 3,29, der Minimalwert 0,74. Die Streubreite stimmte im Wesentlichen mit den theoretischen Berechnungen von Wehner et al. [19] überein. Die gefundenen Quotienten wären theoretisch als Umrechnungsfaktoren von AAK in BAK denkbar. Aufgrund der sehr großen Variabilität sollte aber grundsätzlich in forensischen Gutachten eine Transformation von AAK in BAK und umgekehrt nicht erfolgen. Demzufolge erscheint auch eine Rückrechnung mit „transformierten” BAK-Werten oder die Berücksichtigung von angegebenem Nachtrunk nicht möglich. Insbesondere ist ein strafrechtsrelevanter AAK-Grenzwert auch nicht durch einfache Multiplikation zu errechnen, sondern bedarf einer breiten experimentellen psycho-physiologischen und verkehrsmedizinischen Grundlagenforschung.
