    Notes: Abstract. A closed fish culture recirculation system consisting of 36 20-gallon aquaria in series with a rotating plate biofilter, a diatomaceous earth filter, and an ultraviolet (UV) light sterilizer was evaluated for the effectiveness of UV light in preventing spread of Ichthyophthirius multifiliis. Water from the aquaria, the reservoir, and a valve 29 cm beyond the UV light source was analysed bacteriologically to assess its effectiveness. The spread of I multifiliis from one aquarium to another was controlled with 91 900 μW s/cm8 of UV light. No significant differences in the bacterial counts from the water of the reservoir or the aquaria could be demonstrated when the UV light was either on or off, although a significant difference could be demonstrated between the sterilizer effluent and the reservoir and aquaria.

    Notes: Summary. A prospective study of the treatment of unconsummated marriage was carried out by 16 doctors trained by the Institute of Psycho-sexual Medicine. This training stresses the development of skills in using the doctor/patient interaction therapeutically, rather than in the acquisition of knowledge. The 159 couples admitted to the study had a mean duration of symptoms of 4.2 years; 60% of them had consummated by 6 months and 72% by 24 months. Other improvements in sexual function occurred even among those failing to consummate; 135 couples had previously consulted 253 other agents. The average cumulative length of treatment at the 6-month review was 3 h. Partners attending alone did as well as couples who attended together.

    Asymmetry of gait in normal children demonstrated by polarized light goniometry (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Child 9 (1983), S. 0

    Notes: Summary Polarized light goniometry recordings were obtained from 46 neurologically normal children aged 4–15 years. Asymmetry in terms of thigh and knee angle differences between right and left legs was common in children aged less than 10 years but uncommon in children aged more than 10 years. This asymmetry was predominantly in the direction of more flexion on the right side. The tendency for goniometric asymmetry to mirror asymmetry on clinical examination was slight and did not reach statistical significance. It is suggested that angular asymmetry during gait which occurs in some children under 10 years of age may be related to unequal rates of maturation of the two hemispheres. Other minor neurological asymmetries, neuro-anatomical asymmetries and postural asymmetries which may be found in normal children are discussed.

    A comparison of the thick-target model with stereo data on the height structure of solar hard x-ray bursts (1983)

    Notes: Abstract The height structure of a thick-target solar hard X-ray source is predicted for a beam injected vertically downward with a power-law spectrum and dominated by Coulomb collisional energy losses. This structure is characterised by the ratio of hard X-ray flux from an upper part of the source to that from the entire source, and is essentially a function only of the atmospheric column density ΔN (cm−2) in the upper region. These predictions are compared with the flux ratios at 150 keV and 350 keV observed by two spacecraft for five events in which the solar limb occults part of the source for one spacecraft. In three events the occulting levels h ranged from 0 to 2500 km. For these the theoretical and observed ratios are found to be comparable for values of ΔN in reasonable accord with those found at these altitudes by optical and UV spectroscopic modelling of flare chromospheres. In one event the occultation ratio was observed to rise after the burst peak and it is found that this rise is consistent with an increase in ΔN due to conductively driven chromospheric evaporation. However the energy dependence of the occultation ratio is not consistent with that predicted by the model and it is concluded that non-collisional losses must be significant in beam dynamics. In the other two events, the occultation level h was ≳ 25 000 km. For these the energy dependence of the occultation ratio is comparable with the model predictions. However the values of ΔN required demand extremely high coronal densities and/or acceleration altitudes. Furthermore, the one observed evolution of the occultation ratio is entirely inconsistent with the model. It is concluded that in these, bremsstrahlung emissions other than that from a beam must be important.

    Inversion of synchrotron spectra (1983)

    Notes: Abstract The problem of synchrotron radiation spectra is treated from the viewpoint of deconvolving the spectrum of ultrarelativistic source electrons from the observed photon spectrum. It is shown that for homogeneous sources the problem amounts to inversion of a Meijer transform with a modified Bessel finction kernel. A precise analytic inversion is only possible in the complex plane but Meijer transform tables are available for a wide range of functions. More convenient inversion formulae prove possible by use of a Laplace transform approximation or by analysing the spectra in terms of their integral moments. The filtering property of the transform is also established showing that the contribution to the synchrotron spectrum of high frequency components in the electron spectrum declines exponentially with their frequency. Thus, as with other Laplace-like transforms, only a few terms in an electron spectrum expansion can be deconvolved for any plausible noise level in the synchrotron spectrum.

    Notes: Abstract Cytologic and direct fluorescent antibody techniques were used to detect the presence of Actinomyces israelii and Arachnia propionica in cervicovaginal smears collected from 100 women, 94 of whom did not use intrauterine contraceptive devices. In no case were these organisms found. The possible significance of these results is discussed.

    Notes: Summary The epithelial ultrastructure of the glomerulus of fresh- and sea-water adapted rainbow trout, Salmo gairdneri was examined by scanning and transmission electron microscopy after in vivo-perfusion fixation. Adaptation to seawater for a period of up to 9 weeks was not associated with a change in glomerular size, although after one year in seawater both glomeruli and their capsules were significantly smaller than the glomeruli of freshwater adapted fish. In freshwater adapted trout the epithelial ultrastructure conformed to the general vertebrate pattern, with rounded podocytes, well-defined primary processes and interdigitating pedicels. Adaptation to seawater was associated with a marked increase in the frequency of cytoplasmic microprojections. In many glomeruli there was a flattening of the podocytes, broadening of the primary processes, and areas of closely-packed pedicels were common. These observations are discussed in the light of previous studies on the mammalian kidney and the changes of single nephron function known to be associated with adaptation of trout to increased environmental salinities.
