    Notes: The deuterated dicyanoquinonediimine salt Cu(2-CD3,5-CD3-DCNQI)2, (d6), a highly conductive organic metal, exhibits a phase transition from the metallic to the insulating state at Tc≈60 K. In a wide temperature range we observe an anticoincidence of high conductivity and electron spin resonance (ESR). These experiments were performed simultaneously in our ESR apparatus equipped for application of He pressure up to 200 bar. Near Tc there is a coexistence of conducting (ESR-silent) and insulating (ESR-detectable) domains. This correlation of ESR and conductivity σ points to a percolation limited conductivity. Upper and lower limits of the size of the domains are given. Light shifts Tc to lower temperatures, pressure to higher ones. This could be due to shrinking of the lattice which induces the phase transition when critical structural parameters are approached. This is most probably explained by a simultaneous development of a charge density wave (CDW) and a spin pairing within the DCNQI stack together with the trimerization of the lattice. Systematic measurements by variation of temperature, pressure, and light led to phase diagrams of (d6) and to the understanding of the mechanism of the phase transitions. © 1996 American Institute of Physics.

    Description / Table of Contents: Zusammenfassung Es wird über einen zwölfjährigen Jungen berichtet, der an einer akuten basalen Subarachnoidalblutung nach einer tätlichen Auseinandersetzung — von Augenzeugen nur als Rangelei bezeichnet — mit einem Klassenkameraden verstarb. Als Blutungsquelle wird eine Gefäßruptur im System der Vena cerebri magna Galeni und der Vv. cerebri parvae (internae) auf dem Boden einer möglichen mikrodysontogenetischen Vorschädigung der Gefäße diskutiert.
    Notes: Summary Report of the case of a 12-year-old boy who had died due to massive basal subarachnoid hemorrhage after moderate fight with a class mate. Findings at autopsy and by microscopic examination indicated that a lesion in the system of the great vein of Galen and the internal cerebral veins might have been the source of the bleeding. The nature of an underlying pre-existing vascular change favoring a rupture is discussed on the basis of the clinical history and the pathoanatomic findings.

    Description / Table of Contents: Summary The deflection of a plane turbulent jet in a crossflow is described by a model which takes the effects of entrainment as well as those of crossflow pressure into account. Using this model the centerline and the spread of the jet and the mean velocity averaged over its cross-section can be calculated. Asymptotic analytic solutions are given for the case where the velocity of the unperturbed crossflow is much smaller than that of the unperturbed jet. A comparison of the present calculations with experimental results of other authors shows good agreement.
    Notes: Übersicht Zur Beschreibung der Umlenkung eines ebenen turbulenten Freistrahles durch eine Querströmuug wird ein Modell entwickelt, bei dem sowohl die Einsaugwirkung des Strahles als auch die Druckwirkung der Querströmung auf den Strahl berücksichtigt werden. Hiermit können die Strahlmittellinie, die Strahlbreite und die über einen Strahlquerschnitt gemittelte Geschwindigkeit berechnet werden. Es werden analytische Näherungslösungen für die Fälle angegeben, in denen die Geschwindigkeit der ungestörten Querströmung wesentlich kleiner als diejenige des ungestörten Strahles ist. Ein Vergleich der berechneten Größen mit experimentellen Ergebnissen anderer Autoren zeigt gute Übereinstimmung.

    Notes: Abstract Thin sections in the thickness range down to 3–5 μm were produced from bariumtitanate ferroelectric ceramics. The small signal dielectric constant, as well as hysteresis loops were measured. Significant deviations from the bulk properties were observed, when the thickness of the sample was decreased to the average diameter of the grains. The measured results are discussed proposing a model with internal stresses and a distorted surface layer.

    Evidence for induction of polysaccharide specific B-cell-memory in the 1st year of life: plain Haemophilus influenzae type b - PRP (Hib) boosters children primed with a tetanus-conjugate Hib-DTPa-HBV combined vaccine (1996)

    Notes: Abstract  The lack of an adequate immune response to the major polysaccharide of the Haemophilus influenzae type b (Hib) capsule (polyribosyl ribitol phosphate) (PRP) in very young infants (〈 18 months) can be overcome by conjugating PRP to a T-cell dependent carrier protein. We studied whether administration of a tetanus-PRP conjugate vaccine reconstituted with a diphtheria-tetanus-acellular pertussis-hepatitis B (DTPa-HBV) vaccine as a three dose primary course at 3, 4 and 5 months of age induced PRP-specific immunological memory, by examining the anti-PRP response to a dose of unconjugated PRP given with the DTPa-HBV booster approximately 1 year later. The unconjugated PRP elicited protective anti-PRP antibody levels (≥ 0.15 μg/ml) in all but 3 of the 369 vaccinees, including 13 infants who failed to demonstrate a measurable immune response after the primary course. In a sub-cohort of 54 subjects all had anti-PRP levels ≥ 0.5 μg/ml within 7–14 days of the booster showing a rapid anamnestic type response. Both primary and booster responses were predominantly IgG1 indicating a T-cell dependent response. The DTPa-HBV components elicited protective anti-diphtheria, anti-tetanus and anti-HBs antibody levels in ≥ 98.5% of vaccinees, and immune responses to each of the acellular pertussis vaccine components in 92.3%–97.3% of subjects. Conclusion The tetanus-PRP conjugate vaccine not only elicited a good primary humoral response, but also induced immunological memory so that the infants were able to mount a large and rapid immune response to subsequent exposure to plain PRP, indicating that protection against circulating wild-type Hib had been generated. Successful induction of immunological memory occurred even when there was no measurable humoral anti-PRP response to the primary course. Tetanus-PRP conjugate vaccine can be used in combination with DTPa-HBV vaccine, when administered separately or as a single injection in the same syringe, in primary immunisation schedules at 3, 4 and 5 months of age.

    A grading study of gliomas using computer aided malignancy classification and histologic morphometry (1996)

    Notes: Abstract Forty three cases of astrocytic tumors and mixed gliomas were studied with the aim of evaluating the reproducibility of the Kernohan grading system vis a vis (a) grading using computer-aided malignancy classifier TESTAST 268 and (b) grading by quantitative morphometric evaluation of the various histological parameters of TESTAST 268. These patients were then followed up for variable periods with a maximum of forty months. High inter and intra-observer variability were observed in the Kernohan grading system. TESTAST 268 was found to be simpler, rapid and more reproducible. However, one drawback observed of this system was that it did not completely eliminate inter-observer variability because there was still some subjectivity in assignment of the categorical values against the histological features. Morphometric evaluation of the semiquantitative assignment values of the 4 histological variables in the TESTAST 268 classifier using Zeiss Morphomat-30 revealed a statistically significant difference between the clusters of the measured quantitative values. A repeat grading using TESTAST 268 and categorical assignment values of histological features derived from the absolute values obtained by morphometry resulted in complete elimination of inter-observer variability. Thus, this study highlights the importance of objectivisation using TESTAST 268 and histologic morphometry in the grading of gliomas. However, since this is a preliminary study on a small number of cases, no cut off values of these measurements have been proposed.

    Notes: Abstract Using the nonmagnetic BONANZA detector for the detection of antineutrons and antiprotons, we measured branching ratios of theJ/ψ into baryonic final states. Our measurements give the new results: $$BR\left( {{J \mathord{\left/ {\vphantom {J {\psi \to \overline {\Sigma ^ - } }}} \right. \kern-\nulldelimiterspace} {\psi \to \overline {\Sigma ^ - } }}\Sigma ^ - } \right) = \left( {0.24 \pm 0.26} \right)\% ;BR\left( {{J \mathord{\left/ {\vphantom {J {\psi \to }}} \right. \kern-\nulldelimiterspace} {\psi \to }}\bar nn\pi ^ + \pi ^ - } \right) = \left( {0.38 \pm 0.36} \right)\% $$ and an independent test for the data of the magnetic detectors.
