    Notizen: Summary Cerebral cysticercosis is the result of infestation of the brain with the larval stage of the intestinal tape worm Taenia Solium. The disease, endemic in some parts of the world, especially Mexico, South America, India, Eastern Europe, is still encountered practically all over the world. There appear to be distinct geographical variations not only in the incidence but also the pattern of the disease. The commonly accepted modes of infection do not stand a critical analysis of available epidemiological data. The brain is a site of predilection for this infestation, where it results in meningeal racemose, parenchymatous ventricular or mixed types of lesions. It may thus produce meningo-encephalitis, granulomatous meningitis, ependymitis, focal granulomas, solitary or multiple parenchymatous cysts, hydrocephalus or a combination of these. Clinically its manifestations are protean and often perplexing, consisting, either alone or in combination, of raised intracranial pressure, focal or multifocal or generalized epileptic seizures, signs and symptoms of a focal mass lesion, hydrocephalus or chronic meningo-encephalitis. Important features of the disease are remissions and recurrences. Laboratory diagnostic investigations are generally unrewarding, there being so far, no single completely reliable test. Recent CAT scan studies have been helpful but not always diagnostic. There is no known medical treatment. Excision of a solitary parenchymatous or intraventricular lesion provides gratifying results but the management of diffuse lesions, presenting with raised intracranial pressure (“pseudo-tumour”) is often frustrating. Extensive bilateral decompression, with or without an additional thecoperitoneal shunt, is helpful in some of these cases.

    Notizen: Abstract Thirty cases of anterior encephalocele treated in our centre over an 18-year period (from 1973 to 1990) are presented. At the time of surgery over 60% of the patients were under the age of 2 years, and 40% were aged under 1 year. Only one child was over 10 years of age. Twenty-six patients had the frontoethmoidal type of defect, while two each had frontonasal- and nasoorbital-type lesions. Twenty-five children had varying degrees of hypertelorism. Four had an enlarged head and four microcephaly. In 26 patients one-stage repair of the encephalocele and reconstruction of the orbits was undertaken. A ventriculoperitoneal shunt was performed prior to definitive surgery in three patients with gross hydrocephalus. There was no post-operative mortality. Six patients had postoperative CSF rhinorrhoea, three of them requiring a lumboperitoneal shunt. This study highlights the role of one-stage repair of this defect.

    Notizen: Abstract Measurements of transient magnetic fields in Fe for Coulomb-excited24Mg(2↓)-ions at high velocity confirm strong attenuations as observed earller for single-electron28Si ions. In a measurement in which the beam was stopped in a non-magnetic buffer layer sandwiched between the target and the Fe layer the perturbation was shown to result from the interaction of the heavy Ni beam with the ferromagnet. The attenuations seem to be correlated with the dE/dx of the beam-ions in the ferromagnet.

    Notizen: Abstract From hyperfine interaction studles on free single electron16O(3−) ions. in a time differential mode using the recoil distance technique. It is shown that these ions are polarized when emerging from magnetized thin layers of Fe. The observed degree of polarization $$\overline {P_{1s} } = 0.05(1)$$ , however, is smaller than expected from transient field measurements.

    Notizen: Abstract Salient features of transient magnetic fields are brought out from nuclear spin precession measurements on light ions penetrating polarized Fe-, Ni- and Gd-hosts. At low velocities ion fractions with singleK-shell vacancies, at high velocities H-like charge state fractions, can account for the observed precessions. The data suggest a sharp reduction of theK-shell field at a velocityv ion≃0.5v 0. Large degrees ofK-shell polarization have been derived for C- and O-ions. Measurements in different ferromagnets show that the transient fields scale with the polarized electron density of the host.

    Notizen: Abstract Single and double K-vacancy fractions at sulphur ions inside Gd are measured for ion velocities between 7v 0 and 14v 0 (v 0=c/137) using the probe layer technique. These measurements, in combination with the available transient field (TF) precession data at 8v 0, yield the degree of polarizationp 1s =0.15(3) for such ions in polarized Gd host. This value is considerably smaller than the generally accepted value of 0.24 for light ions. The present results when considered along with the recently reported small values ofp 1s for32S and40Ar ions at a velocity ofZv 0 in Gd suggestvelocity independence andZ dependence in the polarization transfer mechanism for TF.

    Notizen: Abstract Salient features of transient magnetic fields, like the degree of polarization, host dependence etc. emerging from studies of high velocity single-electron light ions,Z ≦ 16, are well described by spin exchange scattering as the polarization transfer mechanism. Inclusion of density enhancement effects of the electrons of the solid in the Coulomb field of the moving ion are necessary for a quantitative understanding of the observed large degrees of polarization of the ions.

The derived values for the degree of polarization of these ions from the available transient magnetic field data at a velocity of 8v 0 in Fe and Ni agrees with the general trends seen for light ions.

    Notizen: Abstract A biphasic continuum model for the flow of intraocular fluid, the aqueous humour, in the trabecular meshwork is proposed in the paper. The model considers the meshwork as a circular ring with uniform thickness of homogeneous, isotropic, viscoelastic material swollen with continuously percolating aqueous humour. The model further assumes the permeability of the meshwork as a function of dilation in its solid phase. The study considers steady and quasisteady states. Approximate solutions to the problem are obtained by Picard's type iterative procedure and computational results for the dimensionless solid displacement, permeability and pressure profiles are presented. It is concluded that intraocular pressure has a permeabilitydecreasing effect, whereas the elasticity of the meshwork shows a permeabilityincreasing effect. Thus, rising intraocular pressure develops a further rise in itself, whereas the elasticity tends to diminish the intraocular pressure through facilitating aqueous outflow.
